The utility model is a pre-pump filter with a self-slag discharge function, which realizes self-cleaning of the filter residue by designing an annular liquid outlet area and a slag discharge area in cooperation with the elastic valve plate. The advantage of the pre-pump filter is that it can effectively improve the operating reliability of the water pump, extend the service life of the pump, reduce maintenance costs, and improve the working efficiency of the system;

[0004] However, the above method still has the following defects in actual use: although it can self-clean impurities, when high-temperature coke appears, it is easy to adhere to the filter area, and if it is not cleaned in time, it is easy to cause the filter to be blocked.

[0005] Based on this, the utility model designs a pre-pump filter that is easy to disassemble and clean high-temperature coke to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to solve the problem that high-temperature coke easily adheres to the filter area when it appears, and the filter is easily blocked if it is not cleaned in time. A pre-pump filter that is easy to disassemble and clean high-temperature coke is proposed.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a pre-pump filter that is easy to disassemble and clean high-temperature coke, including a filter cartridge, a fixing ring overlapped inside the filter cartridge, a fixing cartridge connected to the filter cartridge, a filter screen connected under the fixing ring, two connecting plates connected to the outside of the fixing ring, a clamping structure slidingly connected to the outside of the filter cartridge, the fixing cartridge is connected to the clamping structure, an auxiliary structure is connected under the clamping structure, the auxiliary structure is connected to the outside of the filter cartridge, the clamping structure is clamped to the connecting plate, the connecting plate is connected to the auxiliary structure, the clamping structure includes a turntable and an auxiliary disk, a coil spring is connected to the auxiliary disk, an arc groove is opened in the turntable, an arc plate is connected to the turntable, and the arc plate is clamped in the connecting plate.

[0011] As a further description of the above technical solution: a chute is provided in the filter cartridge, and the connecting plate is clamped in the chute.

[0012] As a further description of the above technical solution: the auxiliary structure includes a positioning plate, a support plate, a first triangular plate and a second triangular plate, and the support plate is connected to the outside of the filter cartridge.

[0013] As a further description of the above technical solution: the positioning plate is connected under the turntable, and the positioning plate is overlapped with the support plate.

[0014] As a further description of the above technical solution: the second triangular plate is connected to the side of the connecting plate, and the first triangular plate is connected to the outside of the filter cartridge.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0016] 1. In the utility model, the clamping structure, the fixing ring, the filter screen and the connecting plate will cause the coil spring to deform when a rotational force is applied to the turntable and the auxiliary disk. When the connecting plate slides in the slide groove, it will intersperse with the arc groove. After the turntable is released, it will be reset by the coil spring. When the turntable is reset, the arc plate above the turntable will be clamped with the connecting plate. The filter can achieve the function of rapid assembly of the filter screen and the filter cartridge through the cooperation between the coil spring, the arc groove and the arc plate. When high-temperature coking materials come into contact with the filter area, they can be replaced in time to avoid the phenomenon of clogging of the filter caused by excessive accumulation of high-temperature coking materials.

[0017] 2. In the present invention, the auxiliary structure, when the rotational force is applied to the auxiliary disk, the positioning plate will overlap with the support plate, and when the filter screen is connected to the filter cartridge, the connecting plate will correspond to the position of the triangular plate 1 through the triangular plate 2, thereby playing a certain auxiliary role for the turntable and the connecting plate, and avoiding the position displacement of the turntable and the connecting plate during operation.

[0029] Specifically, such as Figure 1-3 As shown, an auxiliary ring 306 is connected to the turntable 301, and the auxiliary ring 306 is rotatably connected to the filter cartridge 1. The turntable 301 is connected to the auxiliary disk 302, and the connecting plate 7 is clamped in the arc groove 304. The auxiliary disk 302 is connected to the fixed cylinder 2 through the coil spring 303, and the auxiliary disk 302 is rotatably connected to the outside of the filter cartridge 1.

[0030] By providing the auxiliary ring 306, when the auxiliary disk 302 is affected by the rotational force, the auxiliary ring 306 will be driven to rotate in the filter cartridge 1, so that the auxiliary ring 306 provides a certain support for the rotation of the turntable 301; by providing the arc groove 304, when the connecting plate 7 is connected to the turntable 301, the connecting plate 7 will be inserted into the arc groove 304, so that the arc groove 304 plays a certain role in limiting the connecting plate 7, thereby preventing the turntable 301 from colliding with the connecting plate 7 when the turntable 301 is reset;

[0031] Second embodiment:

[0032] Specifically, such as Figure 4-5As shown, a chute 8 is opened in the filter cartridge 1, and the connecting plate 7 is clamped in the chute 8. The auxiliary structure 4 includes a positioning plate 401, a support plate 402, a triangular plate 1 403 and a triangular plate 2 404. The support plate 402 is connected to the outside of the filter cartridge 1, the positioning plate 401 is connected under the turntable 301, the positioning plate 401 and the support plate 402 overlap, the triangular plate 2 404 is connected to the side of the connecting plate 7, and the triangular plate 1 403 is connected to the outside of the filter cartridge 1.

[0033] By setting the slide groove 8, when the connecting plate 7 is connected to the filter cartridge 1, the connecting plate 7 will slide in the slide groove 8, so that the slide groove 8 plays a certain positioning role for the connecting plate 7, avoiding the position shift of the filter screen 6 when it is connected to the filter cartridge 1; by setting the triangle plate 1 403 and the triangle plate 2 404, when the filter screen 6 is connected to the filter cartridge 1, the connecting plate 7 will correspond to the triangle plate 1 403 through the triangle plate 2 404, so that the connecting plate 7 can realize the function of interpenetration with the slide groove 8 in the filter cartridge 1, avoiding the phenomenon of misalignment when the filter screen 6 is fixed to the filter cartridge 1.

[0034] Working principle: when in use: when the filter screen 6 in the filter cartridge 1 needs to be replaced, a rotational force can be applied to the turntable 301 and the auxiliary disk 302, and the auxiliary ring 306 in the turntable 301 will rotate in the fixed cylinder 2, and the coil spring 303 will deform with the rotation of the auxiliary disk 302. When the turntable 301 moves to the appropriate position, the positioning plate 401 will contact the support plate 402, and the arc plate 305 will be separated from the connecting plate 7, and then the filter screen 6 can be replaced. When the new filter screen 6 is connected to the filter cartridge 1, the triangular plate 2 404 on the surface of the connecting plate 7 can be aligned with the triangular plate 1 403 and a thrust can be applied to it. When the connecting plate 7 slides in the slide groove 8, it will be interspersed with the arc groove 304. After releasing the turntable 301, it will be reset by the coil spring 303. When the turntable 301 is reset, the arc plate 305 above it will be clamped with the connecting plate 7.
