Description

Technical Field

[0001] The utility model relates to the technical field of filter screens and filter materials, in particular to a pull-out and scraping type anti-blocking filter plate. Background Art

[0002] The sieve plate is also called a porous plate, which is suitable for workplaces such as ore washing, screening, grading, slag removal, and mud removal. The sieve plate can be rectangular, square, round, herringbone, rod, narrow hole, rectangular, flower plate, oblong hole, triangular hole, square hole, plum blossom hole, shell hole, fish scale hole and other hole-shaped punching sieve plates.

[0003] The filter plate is used in the environmental protection industry to filter wastewater to remove debris and impurities in the wastewater. Some flocculent debris will adhere to the mesh plate and it is difficult to clean them. Therefore, this application discloses a pull-out and scraping anti-blocking filter plate. Utility Model Content

[0004] The utility model aims to solve the existing problems and provides a pull-out and scraping anti-blocking filter plate.

[0005] The utility model is realized through the following technical scheme: a pull-out scraping anti-blocking filter plate, comprising a frame, a filter screen is arranged in the frame, slots are symmetrically arranged on opposite sides of the side frames of the frame, sliders are symmetrically arranged in the slots, a brush is arranged on the front side of the filter screen, the brush is connected under the brush plate, the brush plate is connected between the sliders, a scraper is arranged on the back side of the filter screen, both ends of the scraper are connected to the slider, one end of a pull rod is symmetrically connected to the scraper and the brush plate, the other end of the pull rod passes through the frame, the end of the pull rod is connected to the end plate, and the outer side of the end plate is connected to a handle.

[0006] As a further improvement to the above solution, a spring is mounted on the pull rod, and the spring is arranged between the end plate and the frame; it is used to reset the pull rod so that the brush and the scraper are reset back to the inside of the frame.

[0007] As a further improvement to the above scheme, notches are symmetrically arranged on the upper and lower sides of the side frame and are arranged on the upper and lower sides of the filter, and U-shaped sliders are clamped in the notches on the upper and lower sides; the U-shaped slider is clamped in the notch, so that the brush and the scraper can move back and forth.

[0008] Compared with the prior art, the utility model has the following advantages: simple structure, reasonable design, novel and unique concept, and uses symmetrically arranged brushes and scrapers to clean the front and back sides of the filter to remove materials or large debris adhered to the filter. At the same time, the brushes and scrapers exert reverse force on the filter to ensure a good filtering effect of the filter and avoid damage to the filter due to single-sided force. In addition, the pull rod is pushed and pulled by the handle to move the brush back and forth to reset, and the force of the spring on the pull rod has a reset function for the brush. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a front structural schematic diagram of the utility model.

[0010] Figure 2 It is a schematic diagram of the reverse structure of the utility model.

[0011] Figure 3 This is a schematic diagram of the cross-sectional installation structure of the filter. DETAILED DESCRIPTION

[0012] The utility model is further described below in conjunction with the accompanying drawings.

[0013] like Figures 1 to 3 As shown in the figure, a pull-out scraping anti-blocking filter comprises a frame 1, a filter 2 is arranged in the frame 1, slots 3 are symmetrically arranged on opposite surfaces of the side frames of the frame 1, sliders 4 are symmetrically arranged in the slots 3 located on the left and right sides and the upper and lower sides of the filter 2, a brush 6 is arranged on the front side of the filter 2, the brush 6 is connected to the bottom of the brush plate 5, the brush plate 5 is connected to the slider 4, a scraper 11 is arranged on the back side of the filter 2, both ends of the scraper 11 are connected to the slider 4, one end of the pull rod 7 is symmetrically connected to the scraper 11 and the brush plate 5, the other end of the pull rod 7 passes through the frame 1, the end of the pull rod 7 is connected to the end plate 8, and the outer side of the end plate 8 is connected to the handle 9.

[0014] As a further improvement to the above solution, a spring 10 is mounted on the pull rod 7 and is disposed between the end plate 8 and the frame 1 ; the spring 10 is used to reset the pull rod 7 so that the brush 6 and the scraper 11 are reset back to the inner side of the frame 1 .

[0015] As a further improvement to the above scheme, slots 3 are symmetrically arranged on the upper and lower sides of the side frame, and are arranged on the upper and lower sides of the filter 2, and U-shaped sliders 4 are clamped in the slots 3 on the upper and lower sides; the U-shaped slider 4 is clamped in the slot 3, so that the brush 6 and the scraper 11 can move back and forth.

[0016] The working principle of a pull-out scraping anti-blocking filter 2: when the filter 2 is used to filter flocs and other debris in wastewater, the flocs adhere to the front side of the filter 2, that is, the mesh surface of the filter 2 facing the inner wall of the container, and the handle 9 applies force to the end plate 8, so that the force acts on the pull rod 7. The displacement of the pull rod 7 drives the brush plate 5 and the scraper 11 to move. At this time, the spring 10 is compressed. During the process of the brush 6 cleaning the flocs on the front side of the filter 2, the scraper 11 also scrapes the back side of the filter 2. The brush 6 and the scraper 11 simultaneously apply force to the front and back sides of the filter 2, and the force directions on the front and back sides are opposite, so as to avoid damage to the mesh plate of the filter 2.

[0017] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
