[0023] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0024] like Figures 1-2 As shown, this embodiment provides a cleaning device for a powder slurry spray drying equipment. The powder slurry spray drying equipment includes a drying tower 1, which is equipped with an atomizer 2. The cleaning device includes a lifting mechanism, a cleaning nozzle 3, and a water supply pipe. The water supply pipe is located inside the drying tower 1, and a cleaning nozzle 3 is installed at one end of the water supply pipe. The cleaning nozzle 3 is located between the atomizer 2 and the inner wall of the drying tower 1. The other end of the water supply pipe extends from the top of the drying tower 1 and is connected to the lifting mechanism. The lifting mechanism is used to control the water supply pipe to move up and down along the height direction of the drying tower 1.

The nozzle head of the cleaning nozzle 3 is configured to rotate under water pressure. The spray angle of the cleaning nozzle 3 ranges from 0° to 110°. The rotation speed of the cleaning nozzle head is adjusted by the water pressure, which is controlled between 0.2 MPa and 0.4 MPa. The water pressure can be adjusted by a water pump, i.e., water is pumped into the water supply pipe by the water pump. Figure 2As shown, the cleaning nozzle 3 has 3 nozzles, and each nozzle sprays water in a fan shape.

Through pre-setting, the servo motor 7 can control the cleaning nozzle 3 to clean for 2-5 minutes at each fixed point position. The lifting height range of the cleaning nozzle 3 is determined according to the height of the drying tower 1 and the cleaning requirement, and generally should be able to cover the area from the top of the tower body to the bottom, so as to ensure effective cleaning of the entire tower inner surface.

[0031] The first water pipes 4 can be connected to the same second water pipe 10 or different second water pipes 10, and can be set according to actual requirements. Each second water pipe 10 can be controlled by one set of lifting mechanisms or by multiple sets of lifting mechanisms, and no specific limitation is made herein.
