For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0025] The following will be combined with the drawings Figures 1-4 Further illustrate the utility model.

[0026] In order to solve the problems in the background art, the application proposes the following technical scheme: a multistage filtering structure of a recyclable waste acid filter.

[0027] The specific technical solution includes a filter bucket 1 and a dirt removal component 3;

[0028] like Figures 1-2 As shown, the filter barrel 1 is equipped with three vertically arranged filter screens 2, which can filter waste acid. A cleaning assembly 3 is installed inside the filter barrel 1 to clean impurities from each filter screen 2. The cleaning assembly 3 includes a motor 301 fixedly installed above the filter screen 2 at the top of the filter barrel 1, a central rod 302 passing through the center of each filter screen 2, and three levers 303 respectively installed above each filter screen 2. 01 can drive the central rod 302 to rotate, the central rod 302 can support the lever 303, the lever 303 can support the impurity removal brush 304, each lever 303 is fixedly sleeved on the outside of the central rod 302, and each lever 303 is fixedly installed with an impurity removal brush 304 that is movably connected to the top surface of each filter screen 2. The impurity removal brush 304 can clean the impurities on the filter screen 2. The central rod 302, lever 303 and impurity removal brush 304 are all located inside the filter barrel 1.

[0029] according to Figure 2 As shown, the motor 301 drives the central rod 302 to rotate counterclockwise. The counterclockwise rotation of the central rod 302 drives the lever 303 to rotate counterclockwise. The counterclockwise rotation of the lever 303 drives the cleaning brush 304 to rotate counterclockwise. The cleaning brush 304 can clean the impurities on the filter screen 2. When the cleaning brush 304 rotates counterclockwise, the front side wall is tangent to the side wall of the central rod 302. Therefore, after the cleaning brush 304 brushes the impurities on the filter screen 2, the cleaning brush 304 can drive the impurities to make centrifugal motion along the central axis of the central rod 302, which can push the impurities to the edge of the filter screen 2, which can help improve the ability of the filter screen 2 to pass waste acid.

[0030] like Figure 1 and Figures 3-4As shown in the figure, one side of the filter barrel 1 is provided with a collection filter assembly 4 for collecting impurities. Four vertical through holes 5 are arranged on the side wall of the filter barrel 1, which can facilitate the communication between the filter barrel 1 and the collection box 401. Each filter screen 2 is located between two adjacent through holes 5. The collection filter assembly 4 includes a collection box 401 movably connected to the outer side wall of the filter barrel 1 and located on one side of each through hole 5. The collection box 401 can be arranged on the through hole 5 to facilitate the collection of impurities and seal the side wall of the through hole 5. Three vertical filter screens 402 are fixedly arranged in the collection box 401. The filter screen 402 can further filter the waste acid carried by the impurities, which is beneficial to the more sufficient filtration of the waste acid. The three filter screens 402 are respectively located in the lower three through holes 5. The top wall of each filter screen 402 is movably connected to the inner top wall of each through hole 5. Two vertical support plates 403 are fixedly arranged in the collection box 401. The support plate 403 can facilitate the collection of impurities. Each support plate 403 is fixedly connected to the upper two filter screens 402.

[0031] When the impurities are pushed to the edge of the filter screen 2 by the impurity removing brush 304, the impurities are continuously accumulated and pushed. The impurities can fall into the collection box 401 through the through hole 5. The impurities in the collection box 401 can fall onto the inner bottom surface of the collection box 401 and the support plate 403. The inner bottom surface of the collection box 401 and the support plate 403 can support the impurities. The waste acid in the impurities flows to the filter screen 402, which can further filter the impurities. The waste acid passing through the filter screen 402 enters the inside of the filter barrel 1, and the impurities are retained in the collection box 401, which is beneficial to the more sufficient filtration of the waste acid and the collection of the impurities.

[0032] As shown in the figure, Figure 1 and Figure 4 The outer side of the collection box 401 is fixedly provided with a compression ring 6, which can support a sealing ring 7.

[0033] As shown in the figure, Figure 1 and Figure 4 The side wall of the compression ring 6 is bonded with a sealing ring 7 arranged outside the collection box 401. The sealing ring 7 can improve the sealing between the compression ring 6 and the outer side wall of the filter barrel 1. Since the compression ring 6 is fixedly connected to the collection box 401 and there is no connecting gap in the middle, the sealing ring 7 can improve the sealing between the collection box 401 and the filter barrel 1. The sealing ring 7 is located between the compression ring 6 and the filter barrel 1.

[0034] As shown in the figure, Figures 3-4 The side wall of the collection box 401 is symmetrically provided with two connecting pieces 8, which can facilitate the support of the collection box 401 after being fixed.

[0035] AsFigure 4 As shown, the bolt 9 is arranged through the side wall of the filter barrel 1 and the connecting plate 8, and is fixed between the connecting plate 8 and the filter barrel 1, so as to fix the collecting box 401 and the filter barrel 1, and facilitate the installation of the collecting box 401.

[0036] The standard parts used in the utility model can be purchased from the market, the special-shaped parts can be ordered according to the description and the drawings, the specific connection mode of each part adopts the conventional means such as bolts, rivets and welding in the prior art, the machinery, parts and equipment adopt conventional models in the prior art, the circuit connection adopts the conventional connection mode in the prior art, and details are not described herein, and the contents not described in detail in the description belong to the prior art known by the person skilled in the art.
