Announcement No. CN217141123U proposes a screening device for the production of dipotassium hydrogen phosphate. The existing screening device is complicated to operate and the screening is time-consuming, which seriously affects the production efficiency of dipotassium hydrogen phosphate. The raw materials to be screened are placed in the screen box, and the screen box is driven by the driving component to move back and forth to achieve the screening effect, so that the raw materials are screened under the screening action of the screen plate. During the screening process, the raw materials are continuously disturbed by the disturbance component, thereby accelerating the screening rate and reducing the time consumption, which is beneficial to improving the production efficiency of dipotassium hydrogen phosphate.

[0003] However, after the screening is completed in the above device, larger raw materials will be accumulated above the screen plate. After the screening is completed, the raw materials located above the screen plate are inconvenient to take out. Utility Model Content

[0006] A further solution is that there are several screening plates, and several screening holes are opened on the upper surface of the screening plates. The aperture of the screening holes on the screening plates gradually decreases from top to bottom. An inclined blocking plate is fixedly connected to the lower surface of the screening plate, and the height of the inclined blocking plate is greater than the height of the through-port.

[0008] Technical effects and advantages of the utility model:

[0009] 1. The multi-stage screening equipment for potassium phosphate salts, the vibration platform drives the screening box to vibrate, and the screening plate in the screening box vibrates to screen the potassium phosphate salts. The setting of multiple screening plates can perform multi-stage screening, and the potassium phosphate salts larger than the aperture of the screening hole are blocked above the screening plate. When these need to be taken out, the drive motor can be started, and the drive motor drives the lead screw to rotate, and the moving bar drives the push plate to move away from the screening plate.

[0010] 2. Before the screening starts, the multi-stage potassium phosphate screening equipment can start the heater to heat the inside of the heating box, and use the fan to transport hot air to the screening box to dry the inside of the screening box. Since potassium phosphate is soluble in water, it can avoid excessive moisture inside the screening box that causes the surface of the potassium phosphate to melt, thereby achieving the effect of easy use.
