[0033] Specifically, when the motor 203 drives the gear 207 to rotate, the inner ring gear 204 is driven to rotate in the upper limiting ring 201 under the assistance of the upper limiting ring 201, thereby driving the arc-shaped plate 208 symmetrically arranged at the bottom of the inner ring gear 204 to rotate circumferentially, thereby achieving the effect of driving the arc-shaped plate 208 to rotate circumferentially.

[0035] Specifically, under the assistance of the lower limiting ring 202, when the arc-shaped plate 208 rotates circumferentially, the T-shaped block 209 is driven to slide circumferentially in the lower limiting ring 202, so that the arc-shaped plate 208 can rotate circumferentially in a vertical state.

[0038] Example 2
[0039] Referring toFigure 4 With Figure 5 , the second embodiment of the utility model, this embodiment is based on the last embodiment, can scrape out after the sodium phosphate block into the push-pull mechanism 3.
[0040] Push-pull mechanism 3, including fixedly installed in the drying tank 1 bottom and the communication pipeline 302, the pipeline 302 one side is provided with box 301.
[0041] Specifically, after the scraping mechanism 2 is scraped into the sodium phosphate block, falls into the pipeline 302, and the block-shaped sodium phosphate is collected through the box 301.
[0042] The inside fixed mounting of box 301 has telescopic rod 304, and the output of telescopic rod 304 is provided with baffle 305, and the upper and lower sides of baffle 305 are symmetrically provided with L-shaped plate 303.

[0046] Working principle: the sodium phosphate spray drying integrated device mainly includes solution preparation, atomization, drying, gas-solid separation and product collection, and the working principle is the same as the existing disclosed one. When the sodium phosphate is sprayed in the inner cavity of the drying tank 1 by using centrifugal force for a long time, a part of the sodium phosphate will be sprayed on the inner wall of the drying tank 1. Because the sodium phosphate is in a wet state when sand blasting, a part of it will adhere to the inner wall of the drying tank 1. Because the inner cavity of the drying tank 1 is a high temperature environment, the sodium phosphate adhering to the inner wall of the drying tank 1 will form a block, stopping the operation of the device. At this time, the operation of the motor 203 is controlled, the output end of the motor 203 drives the gear 207 to rotate, thereby driving the inner ring gear 204 in the upper limit ring 201 to rotate in a circle. When the inner ring gear 204 rotates in a circle, the arc-shaped plate 208 symmetrically installed at the bottom of the inner ring gear 204 rotates. When the T-shaped block 209 rotates in the lower limit ring 202, it ensures that the arc-shaped plate 208 rotates in a circle in a vertical state. The arc-shaped plate 208 drives the fixed rod 205 to rotate, thereby driving the scraper 206 in contact with the inner wall of the drying tank 1 to rotate, and scraping off the blocky sodium phosphate on the inner wall of the drying tank 1. The blocky sodium phosphate after scraping falls into the pipeline 302. The operation of the telescopic rod 304 is controlled, the output end of the telescopic rod 304 drives the baffle 305 to move, thereby opening the communication between the pipeline 302 and the box 301. The blocky sodium phosphate falls into the pipeline 302. A tool is used to clean out the blocky sodium phosphate falling in the pipeline 302. After cleaning, the reverse operation of the telescopic rod 304 is controlled, so that the baffle 305 is blocked in the communication between the pipeline 302 and the box 301.
[0047] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, without necessarily requiring or implying any such actual relationship or order between these entities or operations.
