Description

A device for separating defective alumina carrier balls

Technical Field

The utility model relates to an alumina carrier separation technology, in particular to an alumina carrier defective ball separation device.

Background Art

Alumina carrier refers to white powder or formed aluminum oxide solid, which is the most widely used catalyst carrier, accounting for about 70% of industrial supported catalysts. Alumina has many forms, such as spheres, strips, etc. Not only do different forms have different properties, but even the same form has different properties due to its different sources, such as density, pore structure, specific surface area, etc.

There are often some defective balls after the production of alumina carrier balls. The presence of defective balls will affect the carrier performance, so it is necessary to separate the defective balls from regular balls. However, the existing means lack efficient separation equipment to separate the defective balls from the carrier balls to improve product performance.

Utility Model Content

The technical problem to be solved by the utility model is: how to realize the rapid separation of defective balls and regular balls of alumina carrier balls.

In order to solve the above technical problems, the utility model has obtained the technical solution of the utility model through practice and summary, and the utility model adopts the following technical solution:

A defective alumina carrier ball separation device comprises a frame, which is arranged obliquely along the width direction, a conveying structure is installed on the frame along the length direction, a feed bin is arranged above one end of the conveying structure, a collection port 1 is arranged at the tail of the other end of the conveying structure, and a collection port 2 is installed on one side of the conveying structure, the feed bin, the collection port 1 and the collection port 2 are all installed on the frame, and the collection port 2 is installed on the lower side of the frame.

Preferably, the bottom of the feed bin is installed with beam one and beam two arranged in sequence along the conveying direction of the conveying structure, the bottom of beam one is provided with a baffle, the distance between the bottom of beam two and the conveying surface of the conveying structure is greater than the size of the alumina carrier and less than 2.5 times the size of the alumina carrier, the bottom of the feed bin is provided with a baffle, the baffle is vertically arranged between beam one and beam two, and the distance between the bottom of the baffle, the bottom of the baffle and the conveying surface of the conveying structure is less than the size of the alumina carrier.

Preferably, the conveying structure is a conveyor belt driven by a servo motor.

Preferably, the feed port of the second material collection bin is a flat structure, and a discharge port is provided on the second material collection bin.

Preferably, a screen is provided inside the second aggregate bin, and the screen is suitable for separating the alumina carrier and the ash powder.

Preferably, the second collection bin includes a primary selection area and a secondary selection area. The primary selection area is suitable for collecting the oxide ball carriers separated in the front half of the conveying structure, and the secondary selection area is suitable for collecting the alumina carriers separated in the second half of the conveying structure. The feed ports of the primary selection area and the secondary selection area are both wide-mouth structures, and a discharge port is provided at the bottom.

Preferably, a side of the second material collecting bin away from the frame protrudes upward to form a barrier portion.

Preferably, an elastic pad is provided on the side of the baffle portion facing the frame, or the end thereof gradually approaches the side of the frame.

Compared with the prior art, the utility model has the following beneficial effects:

The utility model adopts a horizontal arrangement of the frame, with the front lower and the back higher. It has been verified by the inventor in practice that regular carrier balls can be obtained when the angle is controlled within the range of 3 to 15 degrees. If the balls are larger or smaller, the separation effect will not be obvious. By discharging the materials from one end of the conveyor belt and the high end of the frame and transporting them horizontally through the conveyor belt, the relatively regular alumina balls will roll down to the second collecting bin by gravity for unified collection. The defective balls will be hindered from falling due to their irregular surfaces during the rolling process, and will be spread on the conveyor belt and transported to the tail together with the conveyor belt, and finally collected and processed in the first collecting bin.

The utility model improves the second aggregate bin, and the improvement lies in adding a screen inside to screen the ash powder and the regular oxide ball carrier, so as to prevent dust from polluting the workshop atmosphere when sorting carriers of different particle sizes in the later stage. At the same time, the second aggregate bin is divided into zones, with the front half set as the primary selection zone and the back half set as the secondary selection zone. The more regular carrier balls will roll first and no longer need to be separated in the later stage. The aluminum oxide balls separated in the secondary selection zone will have a relatively small proportion of defective balls, which can be re-separated and removed as needed to obtain regular carrier balls.

The utility model provides a baffle on the front side of the second collecting bin, and an elastic pad or an end thereof is provided on the baffle gradually approaching one side of the frame, which can reduce the rebound effect of the carrier ball or prevent the carrier ball from falling to the ground after rebounding and causing waste.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

Embodiment 1, as shown in Figures 1 and 2, an alumina carrier defective ball separation device includes a frame 10, the frame 10 is arranged obliquely along the width direction, a conveying structure 20 is installed on the frame 10 along the length direction, a feed bin 30 is arranged above one end of the conveying structure 20, a collection bin 1 50 is arranged at the other end of the conveying structure 20, and a collection bin 2 40 is installed on one side of the conveying structure 20, the feed bin 30, the collection bin 1 50 and the collection bin 2 40 are all installed on the frame 10, and the collection bin 2 40 is installed on the lower end side of the frame 10.

The frame 10 has an inclination angle of 3 to 15°, preferably 8°.

The feed bin 30 is located at the top of the frame 10 .

Wherein, the conveying structure 20 is a conveyor belt driven by a servo motor.

The produced alumina carrier is put into the feed bin 30 and transported to the tail of the conveying structure 20 by the conveying structure 20. During the transportation, the regular carrier balls will roll into the collecting bin 2 40 under the action of gravity. The defective balls have uneven surfaces on their surfaces, so the rolling effect is not obvious or even do not roll at all in severe cases. Then, the regular carrier balls will fall into the collecting bin 2 40 and the defective balls will enter the collecting bin 1 50, thus completing the efficient separation of the defective balls and the regular balls.

Embodiment 2, based on the above embodiment, the following improvements are made, as shown in Figure 3, the bottom of the feed bin 30 is installed with a beam 1 31 and a beam 2 32 arranged in sequence along the conveying direction of the conveying structure 20, the distance between the bottom of the beam 2 32 and the conveying surface of the conveying structure 20 is larger than the size of the alumina carrier and smaller than 2.5 times the size of the alumina carrier, and a baffle 35 is provided at the bottom of the feed bin 30, the baffle 35 is a U-shaped structure with an open top, and the distance between the bottom of the baffle 35 and the conveying surface of the conveying structure 20 is smaller than the size of the alumina carrier.

The output thickness of the alumina carrier balls is precisely controlled by the beam 1 31 and the beam 2 32 , the baffle and the baffle. A larger thickness is not conducive to separation, and a smaller thickness cannot effectively complete the separation.

Embodiment 3, based on the above embodiment, the following improvements are made, as shown in Figure 5, the feed port of the second collecting bin 40 is a flat structure, and the second collecting bin 40 is provided with a discharge port 33. The flat structure, that is, the top is a wide-mouth structure, which is suitable for collecting carrier balls and processing them uniformly.

Embodiment 4, based on the above embodiment, the following improvements are made, as shown in FIG8 , a screen 34 is provided inside the second collecting bin 40 , and the screen 34 is suitable for separating the alumina carrier and the ash powder.

Embodiment 5, based on the above embodiment, the following improvements are made, as shown in Figures 5 and 8, the collecting bin 2 40 includes a primary selection area 41 and a secondary selection area 42, the primary selection area 41 is suitable for collecting the oxide ball carriers separated in the front half of the conveying structure 20, and the secondary selection area 42 is suitable for collecting the alumina carriers separated in the second half of the conveying structure 20, and the feed ports of the primary selection area 41 and the secondary selection area 42 are both wide-mouth structures.

The front half is set as the primary selection area 41, and the back half is set as the secondary selection area 42. The relatively regular carrier balls will first roll down and be collected in the primary selection area 41, and no separation is required at the later stage. The alumina balls separated from the secondary selection area 42 will contain a small proportion of defective balls, which can be re-separated and eliminated as needed to obtain regular carrier balls.

Embodiment 6, based on the above embodiment, the following improvements are made, as shown in Figures 1, 7, 5 and 8, the side of the second collecting bin 40 away from the frame 10 protrudes upward to form a blocking portion 43. The blocking portion 43 is used to block the falling carrier ball to prevent it from falling to the ground.

Embodiment 7, based on the above embodiment, the following improvements are made, as shown in Figures 1 and 7, the side of the baffle 43 facing the frame 10 is provided with an elastic pad or the end gradually approaches the side of the frame 10. The use of the elastic pad can reduce the rebound force, and the use of the end gradually approaches so that the carrier ball will not be separated from the collection end.

The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
