The rotating rod 72 is installed at one side of the third adjusting roller 322 departing from the deviation rectifying assembly 7, and both ends of the rotating rod 72 are hinged with the third adjusting roller 322 and the main body shell 31 respectively.
Under the driving of the driving part 71, the moving shaft can perform linear motion along the length direction of the moving shaft, and drives the end part of the third adjusting roller 322 to deflect to a certain extent in the horizontal plane, so that the filter cloth 23 at the position of the third adjusting roller 322 is stressed and changed, the effect of adjusting the position of the filter cloth 23 is achieved, and the position of the filter cloth 23 can be kept at the center of the roller way.
In order to make the deviation rectifying assembly 7 easier to control, a linear bearing 73 is fixed on the main body shell 31, and the moving shaft of the driving member 71 is slidably connected in the linear bearing 73.
In order to facilitate the uniform adjustment of the filtering device by the staff, a master control box is fixedly connected to the equipment frame 1 at the position of the water inlet. The staff can control each subassembly of filter equipment through the master control case.
The implementation principle of the filtration equipment for quickly and efficiently removing the sludge, sand and oil in the sewage is as follows: after the filtering device is started, domestic sewage enters the water filtering cavity through the sewage pipe 21, the domestic sewage is deposited in the water filtering cavity, and most of the domestic sewage enters the inner cavity of the main body shell 31 after being filtered by the filter cloth 23 and then is discharged from the water outlet pipe 22.
The filter cloth 23 is rotated counterclockwise on the surface of the main body housing 31 by the circulating assembly 3, and the filter residue is brought to the position of the scraper 24. The filter residue is scraped away from the filter cloth 23 by the scraper 24 and then is output to the filter equipment through the residue sliding hopper 241, so that the continuous filtering performance of the filter cloth 23 is ensured, and the dependence of the filter equipment on the flow state of the sewage is further reduced.
When the position of the filter cloth 23 deviates in the continuous use, a worker can control the deviation rectifying assembly 7 to enable the third adjusting roller 322 to deflect, so that the acting force between the filter cloth 23 and the third adjusting roller 322 is changed, the filter cloth 23 is adjusted to the central position of the main body shell 31 in the rotating process, and the stability and the reliability of the filtering device in the continuous sewage filtering process are improved to a certain extent.
The above are preferred embodiments of the present application, and the scope of protection of the present application is not limited thereto, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
