[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] Embodiment 1

[0025] like Figure 1-Figure 3As shown, the present embodiment discloses a filtering and screening device for removing rust and sediment from steel pipes, comprising a box body 1, a top surface of the box body 1 is provided with an opening 101, a plurality of support frames 2 are provided on the inner wall in the vertical direction, a filter frame 3 is movably provided on the support frame 2, a filter screen 4 is provided in the filter frame 3, and the mesh size of the filter screen 4 decreases from top to bottom; a push-pull handle 5 is connected to the side wall of the filter frame 3, and a long hole 102 for the filter frame 3 and the push-pull handle 5 to pass through is provided on the side wall of the box body 1; a limit assembly 6 is provided on the outer wall of the box body 1, and the limit assembly 6 limits and fixes the push-pull handle 5.

[0026] In this embodiment, the support frame 2 is a U-shaped structure, and there are two support frames 2. The two support frames 2 are fixedly connected to the inner wall of the box body 1 respectively; a filter frame 3 is movably provided on the top surface of each support frame 2, and the filter frame 3 is a U-shaped structure. A filter net 4 is fixedly connected to the middle part of each filter frame 3, and the mesh size of the filter net 4 located above is larger than the mesh size of the filter net 4 located below, and the filter net 4 below only allows water to pass through; a push-pull handle 5 is fixedly connected to the outer wall of each filter frame 3, and the push-pull handle 5 is a U-shaped structure.

[0027] The working principle of the above technical solution is as follows: first, the utility model is moved to the lower part of the steel pipe to be cleaned, and then the rust layer at this place can be cleaned with high-pressure water; the rust residue and part of the water after cleaning will fall onto the filter screen 4 in the upper filter frame 3, and part of the rust residue will be retained on the upper filter screen 4, and the other part of the rust residue and water will fall onto the lower filter screen 4, and the part of the rust residue will be retained on the lower filter screen 4, and the water will fall onto the bottom wall of the box body 1 through the filter screen 4 for temporary storage; after the rust layer at this place is cleaned, the utility model can be moved to the next position to be cleaned; when there is a lot of rust residue retained on the filter screen 4, the limit fixation of the push-pull handle 5 is released by the limit assembly 6, and then the push-pull handle 5 is pulled outward to move the filter frame 3 and the filter screen 4 to the outside of the box body 1, so that the rust residue on the filter screen 4 can be recovered.

[0028] By adopting this solution, the utility model greatly improves the convenience of recycling the removed rust residue through the arrangement of the above structure.

[0029] In a further optimized solution, both sides of the support frame 2 are provided with a slide groove 201, a slider 202 is slidably connected in the slide groove 201, and the top surface of the slider 202 is fixedly connected to the bottom surface of the filter frame 3. Specifically, the slide groove 201 is a cross-shaped structure, and the slider 202 has the same structure as the slide groove 201, and the two are adapted; the size of the long hole 102 can meet the requirements of the slider 202, the filter frame 3 and the push-pull handle 5 to penetrate together.

[0030] By adopting this solution, the provided slide groove 201 and the slider 202 can limit the filter frame 3, so that the filter frame 3 can only move in a straight line.

[0031] According to a further optimization scheme, the number of the limiting components 6 is the same as the number of the push-pull handles 5 , and the two correspond one to one.

[0032] Specifically, there are two limit assemblies 6, which are arranged up and down, and are respectively located above the corresponding push-pull handles 5; the limit assemblies 6 include a threaded sleeve 61 fixedly connected to the outer wall of the box body 1, and a limit bolt 62 is threadedly connected in the threaded sleeve 61, and the bottom of the limit bolt 62 is inserted into the push-pull handle 5. The threaded sleeve 61 is arranged vertically, and the top surface of the push-pull handle 5 is provided with an insertion hole 501, and the bottom of the limit bolt 62 is inserted into the insertion hole 501.

[0033] With this solution, by rotating the limiting bolt 62 , the bottom of the limiting bolt 62 can be inserted into the insertion hole 501 or removed from the insertion hole 501 , thereby achieving the effect of limiting and fixing the push-pull handle 5 and the filter frame 3 .

[0034] Further optimizing the scheme, the bottom surface of the box body 1 is equipped with running wheels 7 at the four corners. The running wheels 7 are arranged as universal wheels with built-in brakes. The running wheels 7 are arranged to facilitate the movement of the box body 1.

[0035] In a further optimized solution, a water outlet pipe 8 is fixedly connected to the bottom outer wall of the box body 1, and the water outlet pipe 8 is arranged below the filter screen 4 located at the bottom, and a control valve 9 is installed on the water outlet pipe 8. In this embodiment, one end of the water outlet pipe 8 is connected to the interior of the box body 1, and the water falling on the bottom wall of the box body 1 can flow out to the outside of the box body 1 through the water outlet pipe 8.

[0036] Embodiment 2

[0037] like Figure 4 As shown, based on the above-mentioned embodiment one, the difference from embodiment one is that: the box body 1 of this embodiment two is fixedly installed on a small electric flatbed vehicle 10, and the electric flatbed vehicle 10 reciprocates on a track 11 laid on the ground. A mounting frame 12 is fixedly connected to one side of the electric flatbed vehicle 10, and a nozzle 13 is fixedly installed on the mounting frame 12. The nozzle 13 is connected to an external water source through a pipe, and a water pump is fixedly installed on the pipe.

[0038] In this embodiment, the box 1 is driven by an electric flatbed car 10 to move on the track 11. During the movement, the rust layer on the steel pipe is washed away by high-pressure water sprayed from the nozzle 13. At the same time, the rust residue is filtered and recovered through the filter net 4 in the box 1; by rotating the steel pipe, the rust removal and recovery effect of the entire periphery of the steel pipe can be achieved.

[0039] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
