[0034] The working principle and use process of the present invention are as follows: before use, add an appropriate amount of cleaning liquid into the water storage tank 2, and then place the catalyst to be cleaned inside the cleaning net box 393 (if the cleaning net box 393 is a large block structure, remove the removable cover plate 392, and then control the first position adjustment member 395 to extend so as to clamp and fix the catalyst through the limit clamping plate 396), and then control the third position adjustment member 54 to contract so that the catalyst enters the cleaning liquid;

[0035] The first limit driving plate 33 and the second limit driving plate 35 are controlled to repel each other intermittently, and the cleaning net box 393 is moved back and forth laterally at this time, so that the catalyst is washed by the cleaning liquid. At the same time, the third position adjusting member 54 is controlled to continuously extend and contract. When the adjustable support plate 31 presses the elastic feed pipe 399 to deform it, the cleaning liquid in the elastic feed pipe 399 is sprayed outward through the water spray hole 30 and the adjustable nozzle 391, and the catalyst is further washed by the sprayed cleaning liquid.

[0036] After cleaning is completed, the third position adjustment member 54 is controlled to extend so that the catalyst is located above the cleaning liquid, and then the power of the hot air blower 43 and the electric heating member 45 is turned on. At this time, the cleaned catalyst is dried. At the same time, the first limit driving plate 33 and the second limit driving plate 35 are controlled to intermittently repel each other. At this time, the cleaning net box 393 moves back and forth horizontally, thereby achieving dehydration of the catalyst to improve the drying efficiency of the catalyst;

[0037] Therefore, through the mutual cooperation of multiple structures, the catalyst can be flushed in multiple ways, and the catalyst position can be constantly changed to achieve rapid and sufficient cleaning of the catalyst. Secondly, the present invention can dehydrate and dry the cleaned catalyst to facilitate the user to perform subsequent treatment on the cleaned catalyst. In addition, the present invention can be applicable to catalysts of different types, making the application scope of the pretreatment device wider. In addition, the present invention has a simple structure, is easy to use, and is worthy of promotion and use.

[0038] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
