DETAILED DESCRIPTION

In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

As shown in Figures 1 to 4, a sewage filtering and impurity removal device comprises a sewage treatment cabinet 1 and a filter portion 3 fixedly connected to a treatment chamber 2 provided in the sewage treatment cabinet 1, the filter portion 3 is used for sewage filtering and purification, the sewage filtering and impurity removal device further comprises a partition plate 4 fixed between the lower surface of the filter portion 3 and the lower surface of the treatment chamber 2, one side of the partition plate 4 and a part of the treatment chamber 2 are combined to form a collection chamber 5, the filter portion 3, the partition plate 4 and another part of the treatment chamber 2 are combined to form a filter chamber 6, and the filter portion 3 comprises:

Two filter elements 33 for filtering and purifying sewage.

The arc-shaped lower filter frame 31 is used to support and fix one of the filter elements 33 .

The arc-shaped upper filter frame 32 is used to support and fix another filter element 33. The lengths of the two filter elements 33 are different, and other dimensions and specifications remain the same.

The lower filter frame 31 comprises:

The lower water grid 311 is fixed in the filter chamber 6 and has an arc shape.

Relative to the support bars 312 fixed at both ends of the lower water gate 311 , the opposite surfaces of the two support bars 312 are provided with engaging grooves 313 .

As shown in FIG. 2 and FIG. 3 , in this embodiment, the upper filter frame 32 includes:

The upper water grid 321 fixed in the filter chamber 6 is also in the shape of an arc, and the arc radius of the upper water grid 321 is smaller than the arc radius of the lower water grid 311, and the center height corresponding to the arc of the upper water grid 321 is greater than the circular height corresponding to the arc of the lower water grid 311. At the same time, the arc length of the upper water grid 321 is smaller than the arc length of the lower water grid 311, so that the sewage filtered by the upper filter frame 32 can be completely held from below, the effect of sewage filtration and purification is improved, and it is also convenient for sewage filtration. Impurities left on the filter element 33 can slide into the aggregate chamber 5 under the action of water flow impact force and gravity, and the impurities are collected in a centralized manner, so as to facilitate centralized cleaning in the later stage, and the cycle of efficient filtration of the filter element 33 can also be extended.

The mounting bars 322 are fixed to both ends of the upper water fence 321 , and the opposite surfaces of the two mounting bars 322 are both provided with mounting grooves 323 .

As shown in FIG. 1 , FIG. 2 and FIG. 4 , in this embodiment, the filter element 33 includes:

The filter plate 331 is arranged on the lower water grid 311 .

A water filter net 333 fixedly connected to the fitting groove 332 provided on the filter plate 331 .

The engaging strips 334 are fixed on both sides of the filter plate 331 .

As shown in FIGS. 2, 3 and 4, in this embodiment, the fitting strip 334 matches the fitting groove 313 and the mounting groove 323, and the support strip 312 and the mounting strip 322 are longitudinally distributed in the filter chamber 6, so that the fitting strip 334 can be installed in the fitting groove 313 or the mounting groove 323 by plugging, so that the filter plate 331 can be highly fitted to the surface of the lower water grid 311 or the upper water grid 321, so that the filter net 333 can also be consistent with the shape of the lower water grid 311 or the upper water grid 321, so that the sewage can pass through the two filter plates from top to bottom. When the filter element 33 is removed, the impurities filtered out of the sewage are easily concentrated and slide into the collecting chamber 5 under the impact force of the water flow and gravity, thereby preventing the impurities from accumulating and adhering to the surface of the water filter net 333, which would affect the filtering effect of the water filter net 333, and save the workers from the operation of frequently cleaning the surface of the water filter net 333, thereby reducing the workers' labor intensity. The filter element 33 can also be disassembled and turned over once, and the impact force of the downward flow of sewage can be used to clean the water filter net 333, thereby avoiding the frequent disassembly and cleaning operations of the water filter net 333, extending the cleaning cycle of the water filter net 333, and greatly reducing its cleaning frequency.

As shown in Figures 2 and 3, in this embodiment, the sewage filtering and impurity removal device also includes a drainage groove 9 arranged on the lower surface of the filter chamber 6. The drainage groove 9 is located below the lower filter frame 31, which is convenient for directly discharging the sewage after filtering and purification, and avoids the sewage staying in the sewage treatment cabinet 1 and affecting the effect of sewage filtering and purification.

As shown in FIG. 1 and FIG. 2 , in this embodiment, the sewage filtering and impurity removal device further includes:

A water baffle 7 is fixed to the inner edge of the filter chamber 6 .

A sewage input member 8 is arranged on the upper surface of the sewage treatment cabinet 1, and a water baffle 7 is located on one side of the water outlet of the sewage input member 8, so that the water outlet of the sewage input member 8 is located between the water baffle 7 and the top of the filter part 3, thereby preventing the sewage from impacting the surface of the filter 33 and generating splashes everywhere, affecting the working environment.

As shown in FIG. 1 and FIG. 2 , in this embodiment, the sewage input member 8 includes:

A water delivery box 81 is fixed to the upper surface of the sewage treatment cabinet 1 .

Several water pipe joints 82 are arranged in parallel on the upper surface of the water delivery box 81. When in use, the drain outlet of the wool processing tank is connected to the water pipe joint 82 through a conduit, so that when the sewage in the wool processing tank is discharged, the sewage is preliminarily filtered and purified, so as to clean out wool fibers, soil, gravel and other impurities that are easy to cause blockage in the sewage, avoid these impurities from clogging the subsequent sewage discharge pipes, affect the sewage discharge efficiency, avoid polluting the environment, and facilitate centralized treatment of these filtered impurities.

Working principle: When installing, first insert one of the fitting strips 334 on the filter plate 331 into the fitting groove 313 at the top of the lower water grid 311, or into the installation groove 323 at the top of the upper water grid 321, and then insert the other fitting strip 334 on the filter plate 331 into the fitting groove 313 at the bottom of the lower water grid 311, or into the installation groove 323 at the bottom of the upper water grid 321, and the installation of the filter element 33 can be completed. When removing, just pull the filter element 33 obliquely upward from the middle of the filter element 33 to pull out the filter element 33. The operation is simple and quick, and it is convenient for turning over or replacing at a later time, so as to utilize the impact force during sewage filtration to reversely flush the water filter net 333, so that the water filter net 333 can be kept in a good filtering state for a long time. The impurities filtered out of the sewage slide along the surface of the water filter net 333 into the collecting cavity 5 under the impact of gravity and water flow. The water flow wets the surface of the water filter net 333 and also has a lubricating effect, thereby reducing the resistance of the impurities when sliding down, avoiding the impurities from staying and accumulating on the water filter net 333, and also increasing the speed at which the impurities slide down, so as to facilitate the subsequent centralized cleaning of the collected impurities.

The above description is only the preferred embodiment of the utility model, and the parts not described in the utility model can be implemented by adopting or drawing on existing technologies. Of course, the above description is not a limitation of the utility model, and the utility model is not limited to the above examples.
