Description

Technical Field

[0001] The utility model belongs to the technical field of coating devices for catalysts, and particularly relates to a coating device for automobile exhaust treatment catalysts. Background Technique

[0002] Automobile exhaust is the waste gas generated when an automobile is in use, containing hundreds of different compounds, and the pollutants therein include solid suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead, sulfur oxides, etc. While directly endangering human health, the exhaust gas will also have a profound impact on the environment in which humans live. The sulfur dioxide in the exhaust gas has a strong pungent smell, and when it reaches a certain concentration, it is likely to cause the occurrence of "acid rain", resulting in the acidification of soil and water sources, and affecting the growth of crops and forests. Therefore, an exhaust gas treatment structure is provided in the exhaust pipe of the automobile to make the exhaust gas meet the emission standards before being discharged. When processing the exhaust gas treatment structure, it is necessary to spray the catalyst onto the inner wall of its inner cavity, so a coating device for catalysts is needed for spraying operations.

[0003] The existing catalyst spraying equipment has a single function and can only spray the inner wall of the exhaust pipe singly. If there is a lot of dust and rust in the exhaust gas pipeline, it will affect the spraying effect of the catalyst, and manual cleaning will increase the labor cost. Content of the Utility Model

[0004] The purpose of the utility model is to provide a coating device for automobile exhaust treatment catalysts, which solves the problems that the existing catalyst spraying equipment has a single function and can only spray the inner wall of the exhaust pipe singly. If there is a lot of dust and rust in the exhaust gas pipeline, it will affect the spraying effect of the catalyst, and manual cleaning will increase the labor cost.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a coating device for automobile exhaust treatment catalysts, including a workbench, a linkage assembly and a hose. One side of the upper surface of the workbench is fixedly connected with a fixed block. The linkage assembly includes a threaded block and a driving rod. One end of the driving rod is arranged inside the fixed block and is rotationally matched with it. A first worm gear is fixedly connected to the circumferential side of the driving rod. The first worm gear is arranged outside the fixed block. One end of the driving rod is fixedly connected with a threaded rod. The threaded rod is arranged on one side of the first worm gear.

One end of the mounting bracket is fixedly connected with a circular ring buckle. The hose is arranged inside the mounting bracket, and a guide rod is fixedly connected to the circumferential side of one end of the hose. The guide rod is arranged on one side of the circular ring buckle.

[0007] A number of telescopic sheets are installed inside the circular buckle, and the telescopic sheets are arranged on the circumferential side of the hose. A piece of sandpaper is arranged on one side of the telescopic sheet.

A second worm 502 is rotatably connected inside the installation box 5. One end of the second worm 502 is fixedly connected with a driven rod. The driven rod is arranged outside the installation box 5. A transmission belt 302 is installed between the driven rod and the output end of the motor 3, and a pulley transmission structure is formed among the three.

[0029] A connecting rod is rotatably connected to one side of the installation box 5. One end of the connecting rod is fixedly connected with a second worm gear 503. The second worm gear 503 meshes with the second worm 502. The other end of the connecting rod is fixedly connected with a rotating blade 501, and the rotating blade 501 is arranged outside the installation box 5.

[0030] On one side of the upper surface of the workbench 1, a fixing frame 101 is installed, and a collection groove 103 is provided on the upper surface of the workbench 1 near the fixing frame 101.

[0031] It should be supplemented that during actual use, the exhaust gas pipeline to be sprayed is placed on the fixing frame 101 for fixation. The motor 3 is started, and the forward rotation of the motor 3 drives the first worm 301 to rotate. The rotation of the first worm 301 drives the first worm gear 204 to rotate, and then the driving rod 203 is used to drive the threaded rod 201 to rotate, so that the threaded block 202 drives the mounting frame 401 to extend into the inner wall of the exhaust pipe. At the same time, under the action of the pulley structure, the driven rod is used to drive the second worm 502 to rotate, and then the second worm gear 503 is driven to rotate.

The hose 4 expands to extrude the expansion sheet 61 from the ring buckle 6, so that the frosted paper surface on one side of the expansion sheet 61 is closely attached to the pipe wall. The pipe wall is sprayed through the annular nozzle 402. The motor 3 is started, and the motor 3 rotates in reverse, so that the mounting frame 401 moves outward, thereby scraping the pipe wall through the expansion sheet 61, enabling the pipe wall to be better sprayed, and pushing the scraped dust and rust into the collection groove 103 for the convenience of the staff to handle.
