Description

Technical Field

[0001] The utility model relates to the technical field of tail gas treatment, in particular to a device for repairing and removing dirt from tail gas pipelines in drying rooms. Background Art

[0002] During the painting process, in order to quickly dry the paint on the surface of the object, a drying room is generally used to dry the surface of the parts. However, drying will cause volatile substances to evaporate quickly, and there is a certain amount of tar in the exhaust gas, so the exhaust gas needs to be effectively filtered.

[0003] Existing exhaust filtration first requires coarse filtration with a fine filter, and then the remaining toxic and harmful substances are processed. The filter mesh used for coarse filtration is easily clogged by tar in the exhaust gas, resulting in the need for frequent filter replacement. Therefore, an inspection port is opened on one side of the inspection box to facilitate the disassembly and cleaning of the internal filter. However, it is very inconvenient to disassemble and install the filter through the inspection port, and it takes a lot of time to disassemble and clean the oil stains. Therefore, a maintenance device that is convenient for disassembly and cleaning of the internal filter is needed. The smoke oil also adheres to the inner wall of the inspection box, affecting the filtering work, so it is also necessary to facilitate the cleaning of the internal pipes. Utility Model Content

[0023] The following detailed description of preferred embodiments of the present invention, combined with the accompanying drawings, will facilitate understanding of the advantages and features of the present invention by those skilled in the art, thereby more clearly defining the scope of protection of the present invention. Directional terms used in this invention, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are intended solely to refer to the directions in the accompanying drawings. Therefore, these directional terms are intended to illustrate and facilitate understanding of the present invention and are not intended to limit the present invention.

[0024] like Figure 1-5 The exhaust pipe maintenance and decontamination device for a drying room shown in the figure includes an inspection box 1, an exhaust inlet pipe 2, an exhaust pipe 3, a holder 4, a filter device 5, a cleaning mechanism 6, a guide pipe 7, a sewage cover 8 and an inspection cover 9. The exhaust inlet pipe 2 is installed on one side of the inspection box 1, the exhaust pipe 3 is arranged on the top of the inspection box 1, the holder 4 is fixedly arranged inside the inspection box 1, the filter device 5 is clamped in the holder 4, the cleaning mechanism 6 is installed inside one side of the inspection box 1, and the guide pipe 7 is fixedly arranged on the top of the inspection box 1. On the other side, the sewage cover 8 is installed at one end of the bottom of the maintenance box 1, and the maintenance cover 9 is arranged on the outside of the maintenance box 1. The cleaning mechanism 6 includes an electric telescopic rod 61, a rotating sleeve 62, a connecting pipe 63, a nozzle 64 and a steam pipe 65. The electric telescopic rod 61 is installed on the outside of the maintenance box 1, the rotating sleeve 62 is sleeved on the telescopic end of the electric telescopic rod 61, the connecting pipe 63 is clamped in the inside of the rotating sleeve 62, the nozzle 64 is clamped on the inner side of the top of the connecting pipe 63, and the steam pipe 65 is connected to the bottom of the connecting pipe 63.

[0025] Specifically, the filtering device 5 includes a panel 51 and a filter 52. The filter 52 is fixedly arranged on the inner side of the panel 51. A socket that cooperates with the filter 52 is opened on the surface of the maintenance box 1. The filter 52 is clamped in the inner slot of the base 4. The inner side of the panel 51 is attached to the outer surface of the maintenance box 1 and fixed by screws. The electric telescopic rod 61 passes through and extends to the inside of one side of the maintenance box 1. The steam outlet end of the nozzle 64 is located on the outside of the bottom of the filter 52. A sewage outlet is opened at the bottom of the maintenance box 1. The sewage cover 8 is installed outside the sewage outlet. A sewage guide plate is provided on the inner side of the bottom of the maintenance box 1. The sewage guide plate is inclined toward the sewage outlet at the bottom of the maintenance box 1. The steam pipe 65 is a hose, one end of which is clamped inside the guide pipe 7.

[0026] In this embodiment, the gas generated in the drying room enters the interior of the maintenance box 1 through the exhaust gas inlet pipe 2 under the action of the fan, is preliminarily filtered by the filter device 5, and is output from the exhaust pipe 3 for further filtration and purification. The filter device 5 is composed of a panel 51 and a filter 52. The filter 52 is clamped in the internal holder 4 of the maintenance box 1, so that the holder 4 has a supporting installation effect. The panel 51 and the maintenance box 1 are fixed with screws to achieve a sealing effect, thereby reducing the overflow of unfiltered gas. A handle is provided on the surface of the panel 51, which is convenient for pulling out and replacing the internal filter 52 when the filter device 5 is disassembled.

[0027] Furthermore, during daily use, the fine filter holes on the surface of the filter 52 are easily affected by impurities such as tar in the exhaust gas and become clogged. At this time, high-temperature and high-pressure steam is connected to the steam pipe 65 and input into the interior of the maintenance box 1. After being transmitted through the connecting pipe 63, it is sprayed out from the nozzle 64, acting on the bottom of the filter 52, and under the adjustment of the electric telescopic rod 61, the steam cleaning area is changed to achieve the effect of effectively cleaning the filter 52. During maintenance, the maintenance cover 9 can be opened to manually adjust the direction of the rotating sleeve 62 so that the high-pressure steam acts on the inner wall of the maintenance box 1, thereby cleaning the oil stains adhered to the inner wall of the maintenance box 1. The sewage generated by cleaning will be guided by the inner side sewage guide plate at the bottom of the maintenance box 1 and discharged from the sewage outlet. After opening the sewage cover 8, the sewage can be quickly cleaned to achieve effective maintenance effect.
