Fig. 2 is a schematic perspective view of another direction of a bin with anti-blocking function according to an embodiment of the present disclosure. Fig. 3 is a schematic perspective view of a compressed air pipeline and an annular connecting pipe used in a bin with anti-blocking function according to an embodiment of the present application. Fig. 4 is a schematic perspective view of a vibrating screen used in a bin with anti-blocking function according to an embodiment of the present disclosure.

The embodiment of the application provides a feed bin with anti-blocking function, as shown in fig. 1 and 2, including feed bin main part 100, compressed air pipeline 200, vibration screen 300 and controller (not shown in the figure), wherein, feed bin main part 100 is the container of storage material, and compressed air pipeline 200 is the pipeline of transport and jetting compressed air, and the compressed air of jetting can break up the material, and vibration screen 300 can shake the material, avoids the material to gather, and the controller realizes automatic control.

As shown in fig. 1, the bin main body 100 includes an upper bin body 110 and a lower bin body 120 which are connected up and down, the upper bin body 110 is cylindrical, the lower bin body 120 is in a shape of a circular truncated cone with a big upper part and a small lower part, and the bottom of the lower bin body 120 is an opening, so that the discharge of materials is realized.

As shown in fig. 2, the compressed air pipe 200 is connected to the wall of the lower bin 120, so that compressed air is blown out from the wall of the lower bin 120, and the materials can be scattered. The compressed air line 200 is disposed obliquely downward, i.e., is blown obliquely downward, and also contributes to the falling of the material. The compressed air pipe 200 is provided with a solenoid valve (not shown in the drawing) that controls the opening and closing of the compressed air pipe 200.

Of course, the compressed air conduit 200 needs to be in communication with a source of compressed air to provide compressed air.

As shown in fig. 2, the vibrating screen 300 is disposed at the bottom opening of the lower bin 120, and the vibrating screen 300 vibrates up and down, so as to shake materials up and down, thereby avoiding the materials from being adhered to the bottom opening of the lower bin 120 due to factors such as humidity, and further avoiding the materials from being gradually accumulated, and ensuring that the materials can well and smoothly fall down.

The electromagnetic valve and the vibrating screen 300 are electrically connected with the controller, the controller controls the electromagnetic valve and the vibrating screen 300 to be periodically opened and closed, and the controller controls the electromagnetic valve and the vibrating screen 300 to be started and stopped, so that the materials can be periodically blown, scattered and periodically beaten.

It should be noted that, the purpose of the vibrating screen 300 is not to screen the material, but to shake the material to avoid the material from piling up and adhering to the bottom opening of the lower bin 120, so the grid of the vibrating screen 300 may be as large as possible, and the impact on the falling of the material is avoided. For example, the particle size of the powdery material in the silo may be about 1mm, and the mesh of the vibrating screen 300 may be about 10 times the particle size of the powdery material, so that the powdery material may smoothly fall from the vibrating screen 300 without being affected by the mesh size of the vibrating screen 300.

When the vibrating screen 300 is used, compressed air can be sprayed from the bin wall of the lower bin body 120 through the compressed air pipeline 200, so that the possibility that materials adhere to the bin wall of the lower bin body 120 is reduced, the vibrating screen 300 vibrates at the bottom opening of the lower bin body 120, the materials at the bottom opening can be beaten, the materials are prevented from being accumulated at the bottom opening of the lower bin body 120, and accordingly the materials are prevented from accumulating and blocking.

Compared with the prior art, the bin can blow compressed air through the compressed air pipeline 200, so that materials are prevented from adhering to the bin wall of the lower bin body 120, the materials at the bottom opening of the lower bin body 120 are vibrated through the vibrating screen 300, the materials are prevented from being piled up, the possibility of blockage is reduced, blockage is prevented, and the blanking efficiency is improved.

In some embodiments, as shown in fig. 2, the number of the compressed air pipes 200 is plural, and the plural compressed air pipes 200 are disposed at intervals along the circumference of the lower bin 120, so that substantially all of the circumference of the lower bin 120 can be blown, avoiding adhesion and accumulation of materials.

In some embodiments, as shown in fig. 1 and 2, a plurality of compressed air pipelines 200 are connected through an annular connecting pipe 400, the annular connecting pipe 400 is communicated with an air source through an air inlet pipe 410, a heating wire 420 is arranged in the air inlet pipe 410, compressed air from the air source is heated through the heating wire 420, so that compressed air sprayed from the compressed air pipelines 200 has higher temperature, materials can be heated to a certain extent, the materials can be wetted, the possibility of adhesion of the materials which are not wetted is extremely low, and the problem that the materials possibly adhere to the bin wall of a discharging bin is solved.

It should be noted that, the purpose of the heating wire 420 is to avoid the material from being wet, rather than to heat the material to a certain temperature, so the temperature of the heating wire 420 is not required to be too high, and the material can be dried.

In some embodiments, as shown in fig. 1 and 2, the heating wire 420 is spirally extended along the length direction of the air inlet pipe 410, so that the contact area and contact time between the compressed air and the heating wire 420 can be increased, and the heating effect on the compressed air can be improved.

In some embodiments, the pressure in the compressed air pipeline 200 is 0.2MPa to 0.4MPa, so that the sprayed compressed air has a certain impact force, and the materials can be scattered, so that the materials are prevented from being accumulated in a lump.

Specifically, in some embodiments, the pressure within the compressed air conduit 200 is 0.3MPa. The specific pressure may be appropriately adjusted according to the kind of the material, and is not limited herein.

In some embodiments, the vibratory screen 300 is coated with a release coating to prevent material from adhering to the vibratory screen 300, so as to prevent the mesh of the vibratory screen 300 from becoming smaller and affecting the normal fall of the material. The release coating may be polytetrafluoroethylene, which has good non-tackiness and prevents adhesion of materials.

In some embodiments, the mesh size of the vibratory screen 300 is at least 15mm by 15mm, and the mesh size is about 10 times to 20 times the size of the material stored in the bin, avoiding the vibratory screen 300 from affecting the drop of the material.

In some embodiments, the vibratory screen 300 is an electromagnetic vibratory screen that achieves vibration of the screen by an electromagnetic vibrator, and is simple in structure and reliable in operation.

In some embodiments, the frequency of the vibratory screen 300 is 2500 times/min to 3000 times/min, which is of the type of high frequency vibration, increasing the vibration frequency of the vibratory screen 300, increasing the rapping effect on the material, avoiding material accumulation.
