[0017] The following is combined with Figure 1-2 This application is described in further detail.

[0018] The present application discloses a sand dust removal device for sandblasting and polishing of an evaporator, referring to Figure 1-2, including a dust removal tank 1, the main body of the dust removal tank 1 is square, the top of the dust removal tank 1 is detachably mounted with a top cover 11, the top of the top cover 11 is connected to a dust suction pipe 12, the dust suction pipe 12 is externally connected to a dust collector, and a feed port 13 is also provided on the top cover 11, and an upper equalizing plate 2 is fixed obliquely at a position corresponding to the feed port 13 in the dust removal tank 1, and a lower equalizing plate 3 is also provided parallel to the bottom of the upper equalizing plate 2. In order to facilitate ventilation, air holes are provided on the surfaces of the upper equalizing plate 2 and the lower equalizing plate 3 (not shown in the figure), and there is a gap between the ends of the upper equalizing plate 2 and the lower equalizing plate 3 and the inner wall of the dust removal tank 1, and an iron remover 4 is provided in the gap;

[0019] A spiral feeder 5 is provided on the outer wall of the dust removal tank 1. The top outlet of the spiral feeder 5 is connected to the dust removal tank 1, and the connecting position is set between the upper flow equalizing plate 2 and the lower flow equalizing plate 3. The spiral feeder 5 is used to transport the sand particles at the bottom of the dust removal tank 1 to the lower flow equalizing plate 3. The interior of the dust removal tank 1 is a storage bin 14, and the bottom wall of the storage bin 14 is inclined. The feed end of the spiral feeder 5 is connected to the bottom side wall of the storage bin 14, and a discharge port 15 is provided on the bottom wall of the storage bin 14.

[0020] Reference Figure 1 and Figure 2 The iron remover 4 includes a lifting cylinder 41, a bracket 42, an extension rod 43 and a magnetic rod 44. A makeshift groove is provided on the top cover 11, and the bracket 42 is matched and arranged in the makeshift groove. There are extension parts 421 on both sides of the bracket 42. The lifting cylinder 41 is symmetrically arranged on both sides of the bracket 42. The lifting cylinder 41 is vertically fixed on the top cover 11, and the output end of the lifting cylinder 41 is fixed on the extension part 421 to drive the bracket 42 to move up and down. A plurality of extension rods 43 are evenly fixed at the bottom of the bracket 42, and the magnetic rod 44 is vertically fixed to the bottom end of the extension rod 43. A guide hole is provided on the extension part 421, and a guide rod is fixed at the position corresponding to the guide hole on the top cover 11.

[0021] When the iron filings need to be cleaned, the lifting cylinder 41 drives the bracket 42 to rise, thereby driving the magnetic bar 44 to rise, and the staff can clean the iron filings on the magnetic bar 44.

[0022] The implementation principle of the sand dust removal device for sandblasting and polishing of an evaporator in the embodiment of the present application is as follows:

[0023] Sand enters the upper flow-balancing plate 2 from the feed port 13 and falls into the storage bin 14 under the action of gravity. During this process, the lighter dust in the sand is sucked away by the dust suction pipe 12 on the top cover 11. When the sand passes by the magnetic rod 44, the iron filings in the sand are attracted by the magnetic rod 44, thereby removing the dust and iron filings in the sand.

[0024] By providing a spiral feeder 5, the spiral feeder 5 transports the sand particles in the storage bin 14 to the lower flow equalizing plate 3 and drops them back into the storage bin 14 again. During this process, the dust can be raised again so that it can be sucked away by the dust suction pipe 12, and the iron filings in the sand particles can also be adsorbed by the magnetic rod 44 again. Multiple cycles can ensure that the sand particles are cleaned of impurities.

[0025] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
