Description

Vacuum suction loading and pressure unloading vehicle

The present invention sucks and loads dust or quicklime into the tank using a vacuum suction device, and then vacuum-loaded the cargo loaded into the tank with compressed air to the unloading place to suppress the generation of dust during unloading to increase the unloading efficiency and It relates to an unloading vehicle.

In the production of products in the form of powder, or in cement plants where the generation of dust is extremely heavy, and cement plants that use quicklime as the main raw materials, transporting powdered raw materials has been pointed out from a large perspective. Since the raw material is in the form of a powder, heavy dust is generated when loading or unloading the transport vehicle, which makes transportation work difficult and damages the surrounding environment.

A vehicle conventionally used for transporting the raw material in powder form is loaded into a tank using a separate loading device for loading the raw material of the powder so that dust does not occur, and moves to the unloading place, injecting compressed air into the tank, Unloading raw materials.

In addition, in steel mills where large amounts of dust and dust are generated and piled up in the surroundings or powder materials leak and fall off during transportation, dust collected by using a vacuum suction device is used to cleanly collect dust and powder raw materials accumulated in various places. And powder raw materials are inhaled and collected.

The transport vehicle of the powder raw material for transporting and unloading the contents loaded in the tank using compressed air has to be equipped with a separate loading device so that no dust is generated during loading, thus increasing the installation cost and limiting the loading location. The vacuum suction vehicle that collects dust and powder raw materials accumulated in the tank is unloaded with the dust and powder raw materials sucked into the tank by dumping method, so that a large amount of dust is generated during unloading, which makes the working environment difficult and the manual unloading work is performed. Efficient unloading work is not the situation.

Therefore, there is a need for a vehicle capable of pumping and unloading that does not rely on dumping or manual operation to suppress the generation of dust scattering when loading dust and powder in the loading tank and to limit the location of the loading and to suppress the generation of dust during unloading.

The present invention is to provide a vehicle capable of vacuum suction and loading dust and powder raw materials without generating dust and also injecting compressed air into the tank and capable of pumping and unloading, the present invention is rotatable to suck the dust A suction pipe connected to a cyclone outlet formed by bending a suction boom and a semi-circle is installed, and a tank capable of unloading by a dump method, and sucks air in the tank to make a vacuum so that dust is sucked into the suction boom and the suction pipe. It is characterized in that it comprises a vacuum suction device, and a pumping and unloading device for unloading the loaded dust by injecting compressed air into the tank loaded with the vacuum suction device.

In the present invention, the dust or powder raw materials piled up by vacuum suction is loaded, thereby suppressing the generation of dust and injecting compressed air into the tank to transport and unload the loaded dust or powder raw materials to efficiently carry out the unloading operation.

The vacuum suction load of the present invention sucks air in a tank provided with a loading space with a vacuum suction device to make a vacuum in the tank, where dust or powder raw materials are sucked and loaded, and the compressed dust or powder loaded by injecting compressed air into the tank. Pressurized unloading to unload the raw material is to inject compressed air into the tank to increase the air pressure in the tank to discharge and unload it.

Such an overall configuration of the present invention can be seen by looking at the Figures 1 and 2 shown in the drawings.

On the upper and rear sides of the tank (1) having a space in which dust and powder raw materials are loaded, a suction boom (2) and a suction pipe (3) for sucking dust and powder raw materials are mounted. Installed to be configured to be rotatable to suck the dust accumulated on the side and rear of the vehicle and the suction pipe (3) is configured to be installed by suction-loading coupled to the hose is installed at the rear.

Under the side of the tank (1) is attached a vibrator (5) vibrating by electric force to drop the dust attached to the inner circumferential surface of the tank (1) so that the discharge is made smoothly, the lower side of the air pipe ( A plurality of chambers 71 in which 75 are formed are mounted and a discharge pipe 77 for discharging dust is installed.

The front side of the tank (1) is provided with a vacuum suction device 10 for sucking the air in the tank 1 to make a vacuum state, the vacuum suction device 10 is a suction port (21) for sucking air is a tank ( 1) The air sucked in the inlet 21 is collected through the cyclone dust collector 20 and the bag filter 30 to collect dust or powder mixed with the intake air, and then the micro Into the strainer (microstrainer) 40 is introduced into the outside through the silencer 60 through the vacuum pump 50, the fine particles impurities and dust is filtered and sucks air.

The suction port 21 mounted in the tank 1 is mounted on the front side of the tank 1 as shown in FIGS. 3 to 5 as shown in the drawing. The suction of the powder is prevented and the suction port 21 is connected to the cyclone dust collector 20 to allow the air to be sucked in.

A shutoff valve 23 is installed at the connection portion between the suction port 21 and the cyclone dust collector 20 so that foreign matters can be suppressed into the cyclone dust collector 20 when the vacuum suction device 10 is not operated.

The cyclone dust collector 20 has an outer cylinder 24 having a conical cone portion 25 formed at a lower side thereof in an enclosed space, and an inner cylinder 26 having a short length through which air is sucked is installed. A spiral screw blade 27 is attached between the inner cylinders 26 so that the air sucked into the inlet hole 22 connected to the inlet port 21 on the upper side between the outer cylinder 24 and the inner cylinders 26 is connected to the screw blades 27. Vortex to cause a swirl in the lower cone 25 of the outer cylinder 24.

While the sucked air is swirled in the cone portion 25, the dust or powder having a greater specific gravity than the air falls to the lower discharge hole 28 of the cone portion 25 and is discharged into the sealed space and the air is collected in the upper inner cylinder. Sucked into 26 and passed through an inflow path 29 formed downward again to flow into the bottom of the bag filter 30.

The bag filter 30 is for collecting particulates that are not collected by the cyclone dust collector 20, and is collected by passing the dust mixed in the air into the bag filter and the dust is collected under the filter in the closed space. Sometimes.

The cyclone dust collector 20 and the bag filter 30 are cleaned and replaced after a predetermined period of use to increase dust collection efficiency, and the suction air passing through the bag filter 30 is discharged upward to the micro strainer 40. Impurities and dust in the introduced air are filtered and sucked into the vacuum pump 50.

The driving force of the air in the tank 1 to be in a vacuum state is made by the operation of the vacuum pump 50, and the air discharged from the vacuum pump 50 passes through the silencer 60 to the vacuum pump 50. The noise generated is significantly reduced and emitted.

Since the vacuum suction device 10 becomes a vacuum state in the tank 1, dust or powder is sucked and sucked into the suction boom 2 and the suction pipe 3 and is loaded into the tank 1, and the suction pipe 3 is The dust that is sucked in connection with the cyclone outlet 4 formed by bending a semicircle in the rear of the tank 1 is stacked and stacked from the rear side of the tank 1 by the cyclone outlet 4.

The pumping and unloading device 70 according to the present invention for unloading dust or powder material sucked and loaded in the tank 1 so that dust does not occur is provided with a plurality of chambers 71 concave at the bottom of the tank 1. The discharge pipe 77 is mounted and drawn out from the outside of the tank 1 to the central one side of the chamber 71 in the tank 1, and is formed in each chamber 71, and one discharge pipe 77 is formed from the outside. By being connected to the pipe of the dust discharged to the plurality of discharge pipes 77 are collected in one discharge pipe 77 to be transported to be unloaded.

A coupling valve 79 to which the air hose 76 is coupled is attached to an end of the discharge pipe 77 opposite to the discharge direction so that the compressed air can be directly injected into the discharge pipe 77 so that the discharge pipe 77 is blocked. When the compressed air is discharged and the valve 80 is installed at the distal end of the discharge pipe 77, the pressure feed hose 81 is combined and unloaded to block and prevent the inflow of foreign substances.

The chamber 71 of the pumping and unloading device 70 for injecting compressed air into the tank 1 to unload the dust loaded in the tank 1 is concave and circular as shown in FIGS. A circular plate-shaped filter 72 mounted on the lower part of 1) and having a plurality of small sized air vents 73 is mounted on the inner side of the chamber 71 and attached to the fixing plate 74 to fix the outer surface of the chamber 71. An air pipe 75 is formed on one side of which the air hose 76 is coupled, and compressed air is injected into the air pipe 75 and flows into the inner bottom of the chamber 71 through the vent hole 73 of the filter 72. To be injected into tank (1).

Here, the air pipe 75 to which the air hose 76 is coupled is mounted to the side of the concave chamber 71, and the compressed air is injected along the inner circumferential surface of the chamber 71, causing a tornado to generate a whirlwind. The dust is scattered by the whirlwind and the air pressure increases, but before the compressed air is injected into the tank 1, the pressure of the compressed air is closed by closing the shutoff valve 23 mounted between the inlet 21 and the cyclone dust collector 20. This prevents dust from entering the cyclone dust collector 20.

When the air pressure in the tank 1 is 1 kg / cm 2 or more, the pressure hose 81 is connected to the distal end of the valve 80 of the discharge pipe 77, and when the valve 80 is opened, the discharging formed at the central upper side of the chamber 71 is discharged. Dust and air are introduced into the discharge port 78 of the pipe 77 at the pressure of the compressed air and discharged.

Compressed air injected through the filter 72 is introduced into the tank 1 by the filter 72 attached to the inside of the chamber 71 to prevent the backflow of dust and to prevent the compressed air injected into the chamber 71. Since the dust is scattered, air and dust are mixed to prevent the exhaust pipe 77 from clogging.

Pressurized unloading of compressed air can be unloaded at the height of 15-20m from the ground, thus improving the efficiency of unloading work.

In addition, after opening and closing the discharge door 6 to the rear lower side of the tank 1 so that the loading operation can be performed even in an emergency where the loading operation is difficult due to the injection of compressed air, the tank 1 is inclined by the conventional dumping method. To make it possible.

According to the present invention, the dust or powder raw materials piled up in a vacuum are sucked and loaded, so that they are loaded while suppressing the generation of dust. It will not damage the surrounding environment and can be unloaded even in an emergency.
