Description

Technical Field

[0001] The utility model belongs to the technical field of storage transfer devices, and in particular relates to a storage transfer device for conveying powdery materials. Background Art

[0002] At present, most of the valves used in the reverse storage device are diverter valves, stop valves, flow control valves, gate valves, and flap valves. However, this device has the following defects: 1. The working principle of the reverse storage device is to use the kinetic energy of the airflow to make the bulk material suspended and transported along the chute with the airflow. There is a positive pressure in the trough shell, and it is very difficult to seal the plate and the slot of the upper shell, which can easily cause powder to overflow from the slot and pollute the environment; 2. The gate plate falls directly on the air permeable layer, which can easily cause damage to the air permeable layer over time; 3. There is still a gap between the gate plate and the side wall of the upper shell, and the material cannot be completely cut off. The flap valve opens or closes the valve plate by electric or pneumatic means to control the flow direction or flow of the powdered material. This device overcomes the problem of leakage on the slotted surface of the shell, but the airtightness between the valve plate and the upper shell is not easy to ensure, and leakage may occur when the valve plate is closed.

[0003] Therefore, it is necessary to design a reverse storage device for conveying powdered materials to solve the problem of material leakage, accurately control the flow rate, reduce manual labor intensity, and reduce item loss. Utility Model Content

[0023] like Figure 1 As shown in FIG. 2 , the utility model provides a powder material conveying device, including an elevator 1, a discharge chute, an air conveying chute 3, an electric flow valve 9, a distributor 7, a chute fan 4, a storage bin 6, and a dust collector 20.

[0024] The elevator 1 is vertically arranged, the entrance of the elevator 1 is located at the lower end, and the exit of the elevator 1 is located at the upper end. A discharging chute 2 is arranged at the exit of the elevator 1, the discharging chute 2 is arranged obliquely, the entrance of the upper end of the discharging chute 2 is connected with the exit of the upper end of the elevator 1, and an air conveying chute 3 is arranged at the exit of the lower end of the discharging chute 2. The air conveying chute 3 is arranged obliquely, and the entrance of the upper end of the air conveying chute 3 is connected with the exit of the lower end of the discharging chute 2.

[0025] There are two sets of inclined chute fans 4 arranged below the air conveying inclined chute 3. The outlets of the inclined chute fans 4 are connected to the inside of the air conveying inclined chute 3 through multiple parallel outlet air pipes 5, and the multiple outlet air pipes 5 are arranged along the extending direction of the air conveying inclined chute 3.

[0026] There are four storage bins 6 arranged horizontally below the air conveying inclined chute 3 along the extending direction of the air conveying inclined chute 3.

[0027] There are four distributors 7 arranged on the air conveying inclined chute 3. The four distributors 7 are respectively located above the four storage bins 6. The discharge ports at the lower ends of the distributors 7 are connected to the storage bins 6 below through a vertical distribution pipe 8. The distributors 7 output the materials inside the air conveying inclined chute 3 into the storage bins 6 below.

[0028] An electric flow valve 9 is respectively arranged at the rear side of each distributor 7 on the air conveying inclined chute 3. The electric flow valve 9 includes a housing 10, an electric actuator 11, a swing rod 12, a connecting rod 13, an acting rod 14, a gate plate 15, a gate plate shaft 16, a sealing seat 17, and a breathable cloth 19. The housing 10 is of a square box structure. An inlet is arranged on the front side wall of the housing 10, and an outlet is arranged on the rear side wall of the housing 10. An air inlet 18 is arranged on the bottom plate of the housing 10, and a breathable cloth 19 is arranged inside the air inlet 18 to block the air inlet 18 through the breathable cloth 19. A sealing seat 17 is arranged on the inner side of the rear side wall of the housing 10. An arc-shaped sealing groove is arranged on the sealing seat 17, and the sealing groove is communicated with the outlet of the housing 10. The electric actuator 11 is fixedly arranged at the upper end of the housing 10, and a swing rod 12 is fixedly arranged on the output shaft of the electric actuator 11. One end of the swing rod 12 away from the electric actuator 11 is hinged to one end of the connecting rod 13. A gate plate shaft 16 is rotatably arranged between the left and right inner side walls of the housing 10. One end of the gate plate shaft 16 is fixedly connected to one end of the acting rod 14, and the other end of the acting rod 14 is hinged to the end of the connecting rod 13 away from the swing rod 12. A semi-cylindrical gate plate 15 is fixedly arranged on the gate plate shaft 16. The gate plate 15 faces the sealing seat 17, and the outer diameter of the gate plate 15 is the same as the inner diameter of the sealing groove of the sealing seat 17. The opening or closing of the electric flow valve 9 is controlled by the blocking degree of the gate plate 15 to the sealing groove.

[0029] The air inlet 18 at the lower end of the housing 10 is connected to the outlet of the inclined chute fan 4 through the outlet air pipe 5.

[0030] Above the air conveying chute 3, there are two dust collectors 20, and each dust collector 20 corresponds to two storage bins 6 respectively. At the top of each storage bin 6, there is a dust collection port, and at the dust collection port, there is a dust collection pipe 21. The dust collection pipe 21 is connected to the side inlet of the corresponding dust collector 20. At the outlet at the lower end of the dust collector 20, there is a reflux pipe 22, and the reflux pipe 22 is connected to the reflux port at the top of the storage bin 6. The materials collected by the dust collector 20 are returned to the inside of the storage bin 6 through the reflux pipe 22.

[0031] The working principle of the present utility model is as follows:

[0032] The elevator 1 lifts the materials upward and outputs them into the discharge chute 2. The discharge chute 2 feeds the materials into the air conveying chute 3. The chute fan 4 supplies air into the air conveying chute 3, and the air conveying chute 3 conveys the materials backward in sequence.

[0033] The electric actuator 11 inside the electric flow valve 9 rotates, driving the swing rod 12 to rotate. The swing rod 12 drives the actuating rod 14 to swing through the connecting rod 13. The actuating rod 14 drives the gate plate 15 to rotate around the valve of the gate plate 15, thereby driving the gate plate 15 to rotate inside the sealing groove of the sealing seat 17. When the gate plate 15 completely blocks the sealing groove of the sealing seat 17, at this time, the electric flow valve 9 is closed, and the materials cannot pass through the electric flow valve 9. Then the materials accumulate in front of the closed electric flow valve 9 and are conveyed downward to the corresponding storage bin 6 through the distributor 7 corresponding to the closed electric flow valve 9. When the sealing groove of the sealing seat 17 is exposed by the gate plate 15, at this time, the electric flow valve 9 is opened, and the materials can smoothly pass through the electric flow valve 9 and enter the next section inside the air conveying chute 3. The chute fan 4 inputs air into the housing 10 of the electric flow valve 9 through the air outlet pipe 5 and the air inlet 18 at the lower end of the housing 10, so as to ensure that the materials can smoothly flow inside the housing 10. By controlling the rotation angle of the gate plate 15, the exposed opening degree of the sealing groove can be controlled, thereby controlling the flow rate of the passing materials.

[0034] When the materials enter the inside of the storage bin 6, dust will be generated. The raised material dust enters the dust collector 20 through the dust collection pipe 21. After the dust collector 20 collects the material dust, the collected material dust is returned to the inside of the storage bin 6 through the reflux pipe 22.

[0035] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
