[0012] More than one cleaning liquid injection port can be arranged on the tank.

[0013] The cleaning inlet and outlet are provided with a cleaning inlet and outlet gate valve.

[0014] The tank is provided with a feeding port, and the feeding port is provided with a feeding port gate valve.

[0015] A waste liquid discharge pipe is arranged in the lower part of the tank, the waste liquid discharge pipe penetrates through the tank to the outside of the tank and is communicated and provided with a waste liquid discharge pipe gate valve.

[0016] The tank is provided with a flow blocking device for blocking and hindering the upward movement of liquid and airflow.

[0017] The flow blocking device comprises a hollow long shaft, a column and a flow blocking piece, the lower end side of the hollow long shaft is provided with a certain length and number of columns, and the columns are arranged in a spiral upward direction around the hollow long shaft.

[0018] The spiral arranged columns are provided with a flow blocking piece above, and the flow blocking piece is arranged in a spiral upward direction;

[0019] A nozzle is arranged on the hollow long shaft and is fixed in communication with the rotatable cleaning liquid injection pipe, and the rotatable cleaning liquid injection pipe drives the hollow long shaft to rotate and block the flow.

[0020] The lower end of the hollow long shaft is sealed.

[0021] The settling tank is a closed cavity with a conical bottom flow guide structure, and the closed cavity is provided with a waste discharge gate valve below.

[0022] The settling tank is provided with a settling tank airflow inlet and a settling tank airflow outlet, the settling tank airflow inlet is communicated with the pneumatic conveying airflow outlet through a pipeline, and the settling tank airflow outlet is communicated with the pneumatic conveying airflow generator through a pipeline.

[0023] The working principle of the first embodiment of the application is as follows:

[0024] During the cleaning of solid particles, the pneumatic conveying airflow generator is activated. Pneumatic airflow enters the tank from the cleaning inlet and outlet, exits from the outlet, and then flows through pipelines back into the generator, creating suction at the inlet and outlet. When the solid particles to be cleaned approach the inlet and outlet, they are drawn into the tank by the pneumatic airflow. Because the tank's inner diameter is larger than the inlet and outlet diameters, the conveying capacity of the incoming airflow decreases rapidly, causing the solid particles to be retained within the tank. Simultaneously, a certain amount of cleaning fluid is injected through a rotating cleaning fluid spray pipe. Inside the tank, the cleaning fluid continuously washes away the surface deposits of the solid particles under the turbulence of the airflow until the deposits detach from the surface of the solid particles. The pneumatic conveying airflow generator is then turned off, and the cleaning inlet and outlet lose their pneumatic conveying airflow function. The cleaned solid particles and cleaning fluid mixture fall into the filter cup, where solid-liquid separation occurs and solid particles precipitate out. The rotating cleaning fluid spray pipe then sprays cleaning fluid into the tank again to clean the solid particle residue on the inner wall of the tank. The cleaning fluid that has cleaned the inner wall of the tank carries the solid particle residue out of the cleaning inlet and outlet and falls into the filter cup, where solid-liquid separation occurs, thus completing the solid particle cleaning operation.

[0025] The working principle of the second embodiment of the present invention is as follows:

[0026] During the cleaning of solid particles, the pneumatic conveying airflow generator is activated, the inlet gate valve is opened, and the pneumatic conveying airflow enters the tank through the inlet and exits through the outlet. It then enters the settling tank through the settling tank inlet and exits through the settling tank outlet into the pneumatic conveying airflow generator. This generates suction at the inlet. When the solid particles to be cleaned approach the inlet, they are drawn into the tank by the pneumatic conveying airflow. Because the inner diameter of the tank is larger than the inner diameter of the inlet, the conveying capacity of the pneumatic conveying airflow entering the tank decreases rapidly, and the solid particles drawn into the tank are retained inside. Simultaneously, a fixed obstruction is formed by the rotatable cleaning liquid spray pipe. The nozzle on the hollow long rod shaft of the flow device injects a certain amount of cleaning liquid into the tank, driving the flow-blocking device to rotate. The inlet gate valve is closed, and the inlet and outlet gate valves of the cleaning device are opened. The pneumatic conveying airflow enters the tank from the cleaning inlet and outlet. Under the disturbance of the upward airflow, the cleaning liquid in the tank continuously washes away the adhering substances on the surface of the solid particles. At the same time, the rotating flow-blocking device in the tank blocks and reduces the running height of the solid-liquid mixture thrown upward by the inertia of the pneumatic conveying airflow, reducing the loss of cleaning liquid and increasing cleaning efficiency. A small amount of cleaning liquid and solid particles carried out of the pneumatic conveying airflow outlet settle at the bottom of the settling tank. The cleaning continues until the adhering substances are removed from the surface of the solid particles.

[0027] The pneumatic conveying airflow generator is started, the waste liquid discharge pipe gate valve is closed, the cleaning inlet and outlet gate valve is opened, the cleaning liquid is sprayed into the tank through the nozzle on the resistance flow device, the cleaning liquid in the tank is diluted and renewed, and the solid particles are secondarily cleaned for a certain period of time.

[0028] The pneumatic conveying airflow generator is started, the waste liquid discharge pipe gate valve is closed, the cleaning inlet and outlet gate valve is opened, the cleaning liquid is sprayed into the tank through the nozzle on the resistance flow device, the cleaning liquid in the tank is diluted and renewed, and the solid particles are secondarily cleaned for a certain period of time.

[0029] The pneumatic conveying airflow generator is started, the waste liquid discharge pipe gate valve is closed, the cleaning inlet and outlet gate valve is opened, the cleaning liquid is sprayed into the tank through the nozzle on the resistance flow device, the cleaning liquid in the tank is diluted and renewed, and the solid particles are secondarily cleaned for a certain period of time.

[0030] The waste liquid discharge pipe gate valve is closed, the cleaning inlet and outlet gate valve is opened, the mixture of the solid particles to be cleaned and the cleaning liquid falls into the filter cup and is separated into solid and liquid, and the solid particles are separated out; then the nozzle on the rotating resistance flow device and the cleaning liquid injection port spray cleaning liquid into the tank to clean the residual solid particles on the inner wall of the tank and the resistance flow device; the cleaning liquid that has cleaned the inner wall of the tank and the resistance flow device carries the residual solid particles and flows out of the cleaning inlet and outlet, falls into the filter cup and is separated into solid and liquid, so that the cleaning work of the solid particles is completed.

The resistance flow device can be any device that can block and hinder the upward movement of liquid and airflow, and can be installed and fixed on any position and device inside the tank.
