DETAILED DESCRIPTION

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0030] This implementation method is successful. The specific implementation method is as follows:

[0031] like Figs. 1 to 3 As shown, an automatic cleaning device for the aftercooler of an air compressor in an electrolytic aluminum crane is described. In this embodiment 1, an external air duct 5 is used to connect to the air compressor or other fans. After the air enters the external air duct 5, it is transmitted to each dust blowing pipe 41 through a double-pass pipe 42. There are ten dust blowing pipes 41, and each dust blowing pipe 41 is located above the gap groove of the top fin cover plate 2. High-pressure air is used to blow away the dust, catkins and other impurities blocking the fin cover plate 2. The air pressure is also blown out from the bottom fin cover plate 2 after passing through the frame 1. By adding a DC air blowing cleaning method, daily cleaning can be carried out, which can effectively reduce the high temperature shutdown caused by dust accumulation, and also reduce the number of times that need to be stopped for cleaning, thereby improving the efficiency of the crane and reducing manual labor.

[0032] In addition, the external air duct 5 can also be used in conjunction with a hot air blower to make the air blown into the dust blowing pipe 41 hot air, thereby improving the dust removal effect.

[0033] like Figs. 1 to 3 As shown, in this embodiment 2, an automatic purging device for the aftercooler of an air compressor in an electrolytic aluminum crane is described. The external air duct 5 is connected to the return pipe 7 via a first solenoid valve 6, and the other end of the return pipe 7 away from the first solenoid valve 6 is connected to a second solenoid valve 9. The second solenoid valve 9 is also connected to the outlet pipe 8. During normal use, both the first solenoid valve 6 and the second solenoid valve 9 are closed, and there is no gas inside the return pipe 7. When cleaning is required, the first solenoid valve 6 and the second solenoid valve 9 are opened, and the hot gas inside the frame 1 after heat dissipation is discharged through the outlet pipe 8. A portion of the hot gas enters the external air duct 5 through the return pipe 7 and is mixed with the hot gas from the external high-pressure wind and rain and then sprayed out again through the air nozzle 43. The hot gas helps to loosen the dust, preventing the dust from clumping and clogging the fin cover plate 2 due to water stains or other weather factors, which makes it difficult to clean.

[0034] Need to explain, the mounting plate 31 is through the bolt penetrates the threaded hole 33 and is connected with the threaded groove, can be disassembled to maintain, and the return pipe 7 is also located above the dust blowing pipe 41, does not affect the disassembly and assembly work of the dust blowing pipe 41 and the mounting assembly 3 and other components, very convenient for the maintenance and assembly of the frame 1 as a whole.

[0035] Working principle: through the bolt, the mounting plate 31 is installed with the frame 1, and the mounting bracket 4 is inserted into the inside of the insertion slot 32, so that the dust blowing pipe 41 can be located above the top fin cover plate 2, when the crane stops working, the external air pipe 5 is connected with the air compressor or other air source, so that the high pressure air is delivered to the dust blowing pipe 41 through the external air pipe 5 and is sprayed through the air outlet nozzle 43, and the fin cover plate 2 has a gap heat dissipation part, which is often prone to blockage, resulting in the problem of reduced heat dissipation effect, therefore, each dust blowing pipe 41 is just located above the gap groove, and the dust is pushed out of the gap groove by the vertical high pressure air, and the dust is discharged from the bottom fin cover plate 2, after daily cleaning in this way, the dust is greatly reduced, and the small amount of dust that is not blown out of the bottom fin cover plate 2 is relatively concentrated, which is more convenient for the staff to regularly handle, can reduce the cleaning frequency of shutdown and reduce the labor intensity of the staff, and can effectively ensure the safe temperature of the crane air compressor in the summer high temperature season.

[0036] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
