Referring to fig. 1, as a specific embodiment of the present invention, the pneumatic pulse unloading system includes a compressed gas production mechanism, a gas adjusting mechanism, a gas return noise elimination and dust removal mechanism, and a fluidized bed 140. The gas regulating mechanism includes a buffer gas tank 111, a first pulse solenoid valve 112, a first branch pipe 113, and a main pipe 114. The air inlet of the buffer air storage tank 111 is communicated with the compressed gas production mechanism, and the air outlet is communicated with the input end of the first pulse electromagnetic valve 112. The output end of the first pulse solenoid valve 112 is connected to one end of a first branch pipe 113. The other end of the first branch pipe 113 is connected to one end of the main pipe 114. The other end of the main tube 114 is connected to the gas permeable zone of the fluidized bed 140. The return air noise elimination and dust removal mechanism comprises a noise elimination dust remover 121, a second pulse electromagnetic valve 122, a second branch pipe 123 and a main pipe 114. The air inlet of the noise elimination dust remover 121 is connected with one end of the second branch pipe 123; the other end of the second branch pipe 123 is also connected to one end of the main pipe 114.

In this embodiment, the compressed gas production means is capable of compressing the gas to become compressed gas. Here, the gas may be air, and the source of the raw material is wide. The gas regulating mechanism can regulate the flow rate of the compressed gas entering the fluidized bed 140, greatly improving the unloading effect and further improving the unloading efficiency. The air return noise elimination and dust removal mechanism can carry out dust removal treatment on air return rushing out from the fluidized bed, and can effectively reduce noise caused by gas backflow in the dust removal process. The gas regulating mechanism includes a buffer gas tank 111, a first pulse solenoid valve 112, a first branch pipe 113, and a main pipe 114. The buffer air storage tank 111 can store compressed air, wherein the buffer air storage tank 111 is made of steel, so that the mechanical strength is high, and the pressure resistance is high. The first pulse solenoid valve 112 is capable of regulating the flow rate of the compressed gas such that the flow rate of the compressed gas is banded by the opening and closing of the first pulse solenoid valve 112. The first pulse electromagnetic valve 112 is instantaneously opened, so that the compressed gas in the buffer gas storage tank 111 can instantaneously flow out, the fluidized bed is further vibrated, and the dust removal and unloading effect is effectively improved. When the first pulse solenoid valve 112 is opened, the compressed gas can flow through the gas storage tank 111, the first pulse solenoid valve 112, the first branch pipe 113, the main pipe 114, and the gas permeable zone of the fluidized bed 140 in sequence into the fluidized bed 140. The return air noise elimination and dust removal mechanism comprises a noise elimination dust remover 121, a second pulse electromagnetic valve 122, a second branch pipe 123 and a main pipe 114.

Specifically, in the initial state, the first pulse solenoid valve 112 and the second pulse solenoid valve 122 are in the closed state, and the gas permeable belt of the fluidized bed 140 is in the flat state. When the pressure in the buffer air tank 111 reaches 0.2mpa, the first pulse solenoid valve 112 and the second pulse solenoid valve 122 are ready to be opened. When the pressure in the buffer air tank 111 falls back to 0.14mpa, the first pulse solenoid valve 112 and the second pulse solenoid valve 122 are opened to form a pneumatic pulse. The gas pulses pulse the gas permeable zone of the fluidized bed 140. When the pressure in the buffer air tank 111 is lower than 0.1mpa, the first pulse solenoid valve 112 and the second pulse solenoid valve 122 are closed.

In an embodiment of the present invention, a pressure sensor is disposed in the buffer gas tank 111. The pneumatic pulse unloading system further comprises a programmable logic controller, and the programmable logic controller is electrically connected with the first pulse solenoid valve 112, the second pulse solenoid valve 122 and the pressure sensor respectively. The pressure sensor can sense the pressure in the buffer air tank 111, and control the first pulse solenoid valve 112 and the second pulse solenoid valve 122 to be closed and opened according to the value of the sensed pressure. Here, it should be noted that the process of receiving the pressure value transmitted by the pressure sensor by the programmable logic controller and the logic program executed by the first pulse solenoid valve 112 and the second pulse solenoid valve 122 are all known in the art.

Wherein, the output end of the first exhaust port 1111 is provided with a first relief valve 1112. When the pressure in the buffer air tank 111 is too high, the first safety valve 1112 is opened, and the compressed air in the buffer air tank 111 can be discharged to the outside of the buffer air tank 111 through the first exhaust port 1111 and the first safety valve 1112, so that the purpose of pressure relief is achieved.

In an embodiment of the present invention, the compressed gas production mechanism includes a low-pressure screw air compressor 131, an oil-gas separator 132, and a driving assembly 133. The driving assembly 133 is connected to the rotary rod of the low pressure screw air compressor to drive the rotary rod of the low pressure screw air compressor 131 to rotate. The air outlet of the low-pressure screw air compressor 131 is communicated with the air inlet of the oil-gas separator 132, and the air outlet of the oil-gas separator 132 is communicated with the air inlet of the buffer air storage tank 111. Thus, the air is compressed by the low pressure screw compressor 131 to become compressed air. Then enters a buffer gas storage tank 111 after being processed by an oil-gas separator. Specifically, the drive assembly 133 includes a motor 1331 and a v-belt 1332.

Furthermore, the compressed gas production mechanism further includes an air filter 134, and an air outlet of the air filter 134 communicates with an air inlet of the low pressure screw compressor 131. The air filter 134 can filter air to remove dust from the air.

In an embodiment of the present invention, the second gas outlet 1322 is fixed to the outer sidewall of the oil-gas separator 132, and the second gas outlet 1322 communicates with the inside of the oil-gas separator 132. The output end of the second exhaust port 1322 is provided with a second relief valve 1321. When the pressure in the oil-gas separator 132 is too high, the second safety valve 1321 is opened, and the compressed gas in the oil-gas separator 132 can be discharged to the outside of the buffer oil-gas separator 132 through the second exhaust port 1322 and the second safety valve 1321, so that the purpose of pressure relief is achieved. The first and

second relief valves

1112, 1321 are both pulse relief valves. The pulse type safety valve is flexible in action, small in opening and closing delay and high in accuracy. The first and

second relief valves

1112, 1321 are electrically connected to a programmable logic controller. A pressure sensor is also provided in the gas-oil separator 132, and the pressure sensor in the gas-oil separator 132 is also electrically connected to the programmable logic controller. The pressure sensor in the air-oil separator 132 and the pressure sensor in the buffer air tank 111 transmit the detected pressure values to the programmable logic controller, and the programmable logic controller controls the opening and closing of the first relief valve 1112 and the second relief valve 1321 according to the pressure values.

In an embodiment of the present invention, the first branch pipe 113, the second branch pipe 123 and the main pipe 114 are made of rubber or resin. When the output end of the first pulse solenoid valve 112 is communicated with the ventilation belt of the fluidized bed 140 through the first branch pipe 113 and the main pipe 114, the first branch pipe 113 and the main pipe 114 are made of soft materials, so that the connection is high in air tightness, the abrasion resistance of rubber or resin is high, and the service lives of the first branch pipe 113 and the main pipe 114 are effectively prolonged. When the output end of the second pulse solenoid valve 122 is communicated with the ventilation belt of the fluidized bed 140 through the second branch pipe 123 and the main pipe 114, the connection is relatively airtight due to the fact that the second branch pipe 123 and the main pipe 114 are made of relatively soft materials.
