Detailed ways

In order to further understand the characteristics, technical means, and specific purposes and functions of the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific implementation modes.

As shown in Figures 1-10, the present invention provides:

A grinding wheel production mixing equipment with an inner wall cleaning function, including a mixing tank 1 and a rotary drive bracket 2, a first funnel 3, a second funnel 4 and a scraper 5 arranged in the mixing tank 1;

The mixing tank 1 has a cylindrical inner cavity. The top of the mixing tank 1 is provided with a central feeding opening 101 coaxial with the inner cavity and an edge feeding opening 102 arranged circumferentially around the central feeding opening 101. The mixing tank 1 The bottom end of 1 is provided with a discharge port 103 coaxial with the inner cavity;

The rotary drive bracket 2 is arranged in the inner cavity. The rotary drive bracket 2 has a downwardly extending and rotatable mounting part in the inner cavity; the first funnel 3 is coaxially arranged on the mounting part, and the second funnel 4 is coaxially installed upside down. On the bottom, the second funnel 4 is located at the bottom of the first funnel 3. The narrow mouth of the first funnel 3 is larger than the narrow mouth of the second funnel 4. The wide mouth of the second funnel 4 and the inner wall of the mixing tank 1 form a dropping channel;

The scraper plate 5 is arranged outside the first funnel 3, and the scraper plate 5 can contact the inner wall of the mixing tank 1 and extend along the axis of the inner cavity.

When mixing materials, different materials are put in from the center feeding port 101 and the edge feeding port 102 respectively. The first material falls into the inner cavity from the center feeding port 101 and passes through the narrow openings of the first funnel 3 and the second funnel 4. port, and then discharged outward through the discharge port 103;

During this process, the second material falls into the inner cavity through the edge feeding port 102. The second material first falls on the inner cone of the first funnel 3. Under the action of gravity, the second material falls on the inner cone of the first funnel 3. The inner conical surface of the first funnel 3 slides, thereby causing the second material to collide with the first material at the center of the narrow mouth of the first funnel 3 under the action of gravity, thereby completing the mixing, because the narrow mouth of the first funnel 3 is larger than The narrow mouth of the second funnel 4 allows the first part of the mixed material to pass through the second funnel 4, while the second part of the mixed material falls on the outer cone surface of the second funnel 4. Under the action of gravity, the second part of the mixed material passes through the second funnel 4. The mixed materials pass through the discharge channel and fall on the inner conical surface of the first funnel 3 of the next stage, so that the second part of the mixed materials is changed in the direction of movement and collides with the first part of the mixed materials, thereby completing the second time. For mixing, the first funnel 3 and the second funnel 4 have multiple groups, both of which are arranged in the mixing tank 1, so that the first material and the second material are reciprocally mixed in the inner cavity;

When it is necessary to clean the inner wall of the mixing tank 1, stop putting materials into the mixing tank 1 and start the rotary drive bracket 2, so that the installation part of the rotary drive bracket 2 rotates in the mixing tank 1, and the first funnel 3 and the second funnel 4 are both arranged on the mounting part, so that the mounting part can rotate when the first funnel 3 and the second funnel 4 are in the mixing tank 1, so that the scraper 5 can scrape the inner wall of the mixing tank 1. removal operation to prevent materials from being attached to the inner wall of the mixing tank 1 and affecting the mixing of different types of materials;

In the present invention, by arranging the first funnel 3 and the second funnel 4 in the mixing tank 1, materials of different weights collide in the inner cavity of the mixing tank 1 for mixing. At the same time, the inner wall of the mixing tank 1 needs to be cleaned. At this time, by starting the rotating drive bracket 2, the inner wall of the mixing tank 1 can be cleaned through the scraper 5, thereby preventing the adhered material from affecting the mixing efficiency of the material.

As shown in Figure 8, the mixing equipment also includes an elastic component 6. The inner wall of the first funnel 3 is provided with a first material-moving piece 301 extending in its radial direction. The outside of the wide mouth of the first funnel 3 is provided with a coaxial The mounting ring 302 is provided with an opening 3021 extending in the radial direction on the outer circumferential surface of the mounting ring 302; the outer wall of the second funnel 4 is provided with a second material-picking piece 401 extending in the radial direction; the scraper plate 5 is provided along the radial direction. The radial direction of the inner cavity is slidingly matched with the opening 3021. The scraper plate 5 is elastically connected to the mounting ring 302 through the elastic component 6. When the rotating drive bracket 2 is in a stationary state, the distance between the outside of the scraper plate 5 and the axis of the inner cavity is smaller than the inner cavity axis. The radius of the cavity.

When different types of materials are put into the mixing tank 1 for mixing, the first funnel 3 and the second funnel 4 can be rotated in the mixing tank 1 by starting the rotating drive bracket 2. When the materials fall into the first funnel 3 or the second funnel 4, the rotating first material-driving piece 301 and the second material-driving piece 401 can generate a rotational force on the materials falling on them, thereby allowing the materials to be mixed more evenly in the mixing tank 1 , and the scraper plate 5 is arranged outside the wide mouth of the first funnel 3 through the mounting ring 302, which makes the scraper plate 5 in contact with the inner wall for a long time when the first funnel 3 and the second funnel 4 are rotating and mixing. It will cause it to scratch the inner wall of the rotating drum, so it is necessary to keep the scraper plate 5 from contacting the inside of the mixing tank 1 when the first funnel 3 and the second funnel 4 are rotating and mixing, that is, by connecting the scraper plate 5 with the inside of the mixing tank 1 The opening 3021 is slidingly connected, and the scraper plate 5 and the mounting ring 302 are elastically connected through the elastic component 6, so that when the first funnel 3 rotates at a low speed, the outside of the scraper plate 5 cannot contact the inner wall of the mixing tank 1 , to prevent the scraper plate from scratching the inner wall. When the rotating drive bracket 2 drives the second funnel 4 to rotate at a high speed, the opening 3021 extends along the radial direction of the mounting ring 302, and at the same time, the scraper plate 5 is aligned with the radial direction of the mounting ring 302. The opening 3021 slides and fits, so that the scraper plate 5 overcomes the elastic force of the elastic component 6 under the action of centrifugal force and conflicts with the inner wall of the mixing tank 1. The rotating scraper plate 5 cleans the inner wall of the mixing tank 1, thereby Prevent materials from adhering to the inner wall of the mixing tank 1.

As shown in Figure 6, the scraper plate 5 is provided with a connection port 501 near the opening 3021. The elastic component 6 includes a rubber ring 601, a first fixed pin 602 and a second fixed pin 603. The first fixed pin 602 and the second fixed pin The pins 603 are all arranged on the mounting ring 302. The first fixing pin 602 and the second fixing pin 603 are located on both sides of the scraper plate 5. The rubber ring 601 passes through the connection port 501 and its two ends are respectively sleeved on the first fixing pin. 602 and the second fixing pin 603.

A connection port 501 is provided on the scraper plate 5 close to the opening 3021, and the first fixing pin 602 and the second fixing pin 603 are arranged on the mounting ring 302 and located on both sides of the connection port 501, and the rubber ring 601 is passed through connection port 501, and the two ends of the rubber ring 601 are respectively sleeved on the first fixing pin 602 and the second fixing pin 603, which requires the scraper 5 to overcome the elastic force of the rubber ring 601 so that its outside is in contact with the mixing tank. 1 are in contact with each other, and the pin caps of the first fixing pin 602 and the second fixing pin 603 can prevent the end of the rubber ring 601 from detaching, and facilitate installation and disassembly.

As shown in FIG. 9 , the scraper plate 5 fits and slides with the opening 3021 to prevent the scraper plate 5 from sliding along the axis direction in the inner cavity.

By fitting and sliding the scraper plate 5 with the opening 3021, the scraper plate 5 cannot slide towards the opening 3021 along the axis of the mixing tank 1, and thus the scraper plate 5 can only mix materials along the opening 3021. The radial displacement of the tank 1 can make the overall structure more stable, so that the scraper 5 needs to overcome the elastic force of the elastic component 6 before it can contact the inner wall of the mixing tank 1, thereby preventing the first funnel 3 and the second When the funnel 4 rotates and mixes, the inner wall of the mixing tank 1 is scratched due to the long-term contact of the scraper 5.

As shown in FIG. 9 , the connection port 501 and the elastic component 6 are both located at the bottom of the opening 3021 .

By arranging the connection port 501 and the elastic component 6 at the bottom of the opening 3021, the unloaded material cannot directly contact the connection port 501 and the elastic component 6, thereby preventing the material from being blocked in the connection port 501, and at the same time preventing the material from affecting the elasticity. The impact of the component 6 reduces the life of the elastic component 6, thereby improving the stability of the scraper plate 5 and the elastic component 6.

As shown in Figure 6, the mounting ring 302 is provided with a mounting groove 3022 that is inclined to its radial direction and runs through the opening 3021; the mixing equipment also includes a forward and reverse rotation locking assembly, and the forward and reverse rotation locking assembly includes an abutment block 701 and a spring 702 , the abutment block 701 is slidably disposed in the abutment groove 3022 along the extension direction of the abutment groove 3022, the spring 702 is disposed in the abutment groove 3022, and the two ends of the spring 702 abut against the opposite ends of the abutment groove 3022 and the abutment block 701 respectively. .

When it is necessary to control the rotation speed of the first funnel 3 to prevent the outside of the scraper plate 5 from contacting the inner wall of the mixing tank 1, this control method is more complicated. The scraper plate 5 and the mounting ring 302 are controlled by the forward and reverse rotation locking assembly. Phase locking, that is, when the first funnel 3 rotates forward, the forward and reverse rotation locking mechanism can lock the scraper plate 5 and the opening 3021 to prevent the scraper plate 5 from direct contact with the inner wall of the mixing tank 1; When the funnel 3 rotates in the opposite direction, the forward and reverse rotation locking mechanism can release the scraper plate 5 relative to the opening 3021, so that the scraper plate 5 can slide in the opening 3021;

By opening a mounting groove 3022 in the mounting ring 302 that penetrates one side of the opening 3021 and is inclined with the radial direction of the mounting ring 302 , the abutting block 701 is slidably disposed in the mounting groove 3022 , so that the abutting block 701 is in the mounting groove 3022 It can slide along its extension direction, and elasticity is set in the placement groove 3022, so that when the first funnel 3 is stationary, the abutment block 701 abuts the scraper plate 5 through the elastic force of the spring 702. When the first funnel 3 is at rest, When rotating in the direction, the contact block 701 can contact the scraper plate 5 under the action of the placement groove 3022, centrifugal force and the elastic force of the spring 702, so that the scraper plate 5 cannot slide toward the opening 3021; when the third When a funnel 3 rotates in the opposite direction, the abutting block 701 generates a differential speed relative to the mounting ring 302, causing the abutting block 701 to move toward the inside of the mounting groove 3022. The abutting block 701 overcomes the elastic force of the spring 702 and releases the scraping material relative to the opening 3021. The scraper plate 5 makes the scraper plate 5 overcome the elastic force of the elastic component 6 under the action of centrifugation and contact the inner wall of the upper mixing tank 1, thereby cleaning the inner wall of the mixing tank 1.

As shown in Figure 6, the connection between the scraper plate 5 and the opening 3021 is provided with tooth slots at equal intervals; the abutting surface of the contact block 701 and the scraper plate 5 is provided with racks that can engage with the tooth slots at equal intervals. 7011.

By providing tooth grooves at the connection between the scraper plate 5 and the opening 3021 and setting racks 7011 at the contact surface between the abutment block 701 and the scraper plate 5 , when the abutment block 701 abuts on the scraper plate 5 , the tooth grooves and the rack 7011 can mesh with each other, thereby increasing the friction between the abutment block 701 and the scraper plate 5 to prevent the scraper plate 5 from passing through the larger when the first funnel 3 rotates forward at high speed. The centrifugal force directly breaks away from the contact force of the abutment block 701 and slides in the opening 3021, so that only when the first funnel 3 rotates in the opposite direction, the abutment block 701 slides in the placement hole so that the rack 7011 is separated from the tooth groove. Only then can the material plate 5 slide on the opening 3021 to scrape off the material on the inner wall of the mixing tank 1.

As shown in Figure 10, the top of the mounting ring 302 is also provided with a coaxial arc-shaped block 303. The top of the arc-shaped block 303 is inclined and extends toward the axis of the inner cavity.

Since the top of the mounting ring 302 is flat, there is a possibility of materials docking or adhering to the top of the mounting ring 302. The arc block 303 is coaxially located on the top of the mounting ring 302, and the top of the arc block 303 is directed toward the top of the mounting ring 302. The axial direction of the mixing tank 1 is tilted, so that the inner side of the arc-shaped block 303 is inclined, so that the material slides downward on the inclined surface and cannot be accumulated on the top of the mounting ring 302.

As shown in Figure 7, the mixing tank 1 includes a tank body 104 with a top opening 3021 and a tank lid 105 provided on the top of the tank body 104. The center feeding port 101 and the edge feeding port 102 are located on the tank lid 105, and the discharge port 103 is located on the tank lid 105. At the bottom of the tank 104, the rotary drive bracket 2 includes an external ring gear 201, a gear 202, a mounting rod 203 and a motor 204. The external ring gear 201 is coaxially disposed between the tank 104 and the tank lid 105, and the gear 202 rotates is disposed on the outside of the tank 104, the gear 202 meshes with the external ring gear 201, the mounting rod 203 extends downward from the bottom end of the external ring gear 201 to the inner cavity of the tank 104, the first funnel 3 and the second funnel 4 are arranged on the mounting rod 203.

The tank body 104 and the tank lid 105 form an inner cavity for mixing materials, so that the central feeding port 101 and the edge feeding port 102 are located on the tank lid 105, and the discharge port 103 is located at the bottom of the tank body 104, thereby realizing feeding. and discharging materials. When the motor 204 is started, its output shaft can drive the gear 202 to rotate outside the tank 104, and the gear 202 meshes with the external ring gear 201, so that the external ring gear 201 is between the tank 104 and the tank lid 105. The rotation can drive the downwardly extending mounting rod 203 to rotate stably in the inner cavity, and at the same time, can drive the first funnel 3 and the second funnel 4 to rotate in the inner cavity, so that the scraper 5 can rotate against the inner wall of the mixing tank 1 of cleaning.

As shown in Figures 3, 7 and 10, the inner diameter of the bottom end of the inner cavity 1 gradually decreases downward, and the bottom end of the scraper plate 5 is bent to fit with the bottom end of the inner cavity.

By gradually reducing the inner diameter of the bottom end of the inner cavity downward, the bottom end of the scraper plate 5 is bent to match the bottom end of the inner cavity, so that the mixed materials cannot accumulate in the inner cavity of the mixing tank 1 The bottom end of the scraper plate 5 can be used to clean the bottom end of the inner cavity of the mixing tank 1 to prevent materials from adhering.

The above embodiments only express one or several implementation modes of the present invention, and their descriptions are relatively specific and detailed, but should not be construed as limiting the patent scope of the present invention. It should be noted that, for those of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the scope of protection of the patent of the present invention should be determined by the appended claims.
