[0027] Wherein, it also includes a mounting frame 21, the filter cloth 2 is fixedly mounted on the mounting frame 21, the mounting frame 21 is plugged into the inside of the filter tube 14, and an insert block 211 is integrally formed at the bottom of the mounting frame 21, the insert block 211 is engaged and snap-fitted into the inner wall of the filter tube 14, and the top of the mounting frame 21 is fixedly connected to the outer wall of the filter tube 14 by bolts. By mounting the filter cloth 2 on the mounting frame 21, it is convenient to disassemble and assemble the filter cloth 2, and the filter cloth 2 is in a taut state on the mounting frame 21, so that the cleaning component can effectively clean the inside of the filter cloth 2, and the insert block 211 is used to limit the mounting frame 21 and increase the stability of the installation of the mounting frame 21.

[0028] Among them, the sedimentation bottle 3 is a plastic transparent bottle, and the sedimentation bottle 3 is threadedly connected to the filter tube 14. The upper end opening of the sedimentation bottle 3 is located on the inner side of the filter cloth 2. The transparent sedimentation bottle 3 can intuitively observe the amount of sediment inside it, which is convenient for timely cleaning of the sedimentation bottle 3. The sedimentation bottle 3 is threadedly connected to the filter tube 14, which facilitates the disassembly and cleaning of the sedimentation bottle 3.

[0029] Among them, the filter cloth cleaning component includes a driving motor 4 fixedly installed on the top of the filter tube 14, a first bearing 5 is fixedly installed on the top of the filter tube 14, the output shaft of the driving motor 4 is fixedly installed in the inner ring of the first bearing 5, and the output shaft of the driving motor 4 extends into the interior of the filter tube 14 and is fixedly connected to the first bevel gear 41 through a coupling; it also includes a fixing rod 6 fixedly installed inside the filter tube 14, a second bearing 61 is fixedly installed on the fixing rod 6, a second bevel gear 62 is fixedly connected in the inner ring of the second bearing 61, one end of the second bevel gear 62 is fixedly connected to a mounting rod 63, and one end of the mounting rod 63 is fixedly connected to a cleaning brush 7. When a large amount of sludge is attached to the inner surface of the filter cloth 2, the first bevel gear 41 is driven to rotate by starting the driving motor 4, the first bevel gear 41 drives the second bevel gear 62 to rotate, and then drives the cleaning brush 7 to rotate. The rotation of the cleaning brush 7 can clean the sludge on the surface of the filter cloth 2, and the cleaned sludge falls into the interior of the sedimentation bottle 3, wherein the width of the cleaning brush 7 is narrow, which can reduce water resistance.

[0030] The cleaning brush 7 comprises a plate body and bristles fixedly mounted on the plate body. The bristles are nylon bristles. The nylon brush is durable and wear-resistant, can achieve an effective polishing effect, and has a long service life.

[0031] The first bearing 5 is a sealed bearing to prevent sewage from seeping out from the motor output shaft.

[0033] As is well known to those skilled in the art, the working principle and wiring method of the drive motor 4 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can select any model thereof according to their needs or convenience.

[0034] Working principle: when in use, the waste gas enters the waste gas treatment tank 1 from the waste gas inlet pipe 11, and the nozzle 121 is opened to spray the waste gas entering the tank body. The spray water contacts the waste gas to generate water dust beads that fall on the inner bottom of the waste gas treatment tank 1, and flow into the sedimentation bottle 3 along the inner bottom slope of the waste gas treatment tank 1. As the waste water inside the sedimentation bottle 3 increases, the water level rises and overflows the filter cloth 2. The filter cloth 2 filters the waste water, and the filtered waste water is discharged from one end of the filter tube 14.

[0035] During this period, when the wastewater flows into the sedimentation bottle 3, it will be precipitated, so that the sludge in the wastewater falls to the bottom of the sedimentation bottle 3. When the sedimentation bottle 3 is full of sludge, the sedimentation bottle 3 is separated from the filter tube 14 by rotating, so as to facilitate the cleaning of the precipitated sludge in the sedimentation bottle 3.

[0036] When it is found that the water output of the filter tube 14 is not smooth, the first bevel gear 41 is driven to rotate by starting the driving motor 4, and the first bevel gear 41 drives the second bevel gear 62 to rotate, thereby driving the cleaning brush 7 to rotate. The cleaning brush 7 rotates to clean the sludge on the surface of the filter cloth 2, and the cleaned sludge falls into the interior of the sedimentation bottle 3, so that the normal filtering use of the filter cloth 2 is restored;

[0037] The waste gas treatment tank 1 may be provided with a plurality of filter tubes 14 to increase the efficiency of waste water discharge and reduce the number of cleaning times of the sedimentation bottle 3 .
