Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a T-shaped horizontal filter. Background Art

[0002] A filter is a small device for removing a small amount of solid particles in a liquid, which can protect the normal operation of the device. When a fluid enters a filter cartridge provided with a filter screen of a certain specification, its impurities are blocked, and the clean filtrate exits from the filter outlet. In order to ensure the permeability of the liquid, the filter element needs to be periodically taken out for cleaning. To take out the filter element, the flange cover needs to be disassembled first.

[0003] Traditional filters need to replace the entire filter element to meet the requirements. Moreover, the structure of traditional T-shaped filters is complex, the filter element is inconvenient to disassemble, and the maintenance is difficult. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a T-shaped horizontal filter, which overcomes the deficiencies of the prior art and effectively solves the problems of complex structure, inconvenient disassembly of the filter element and difficult maintenance in the prior art for traditional T-shaped filters.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

One end of the T-shaped pipe is connected with a water inlet mechanism, and the water inlet mechanism includes a water inlet pipe, a limit ring fixed at one end of the water inlet pipe, a first external thread pipe fixed on the outer wall of one side of the limit ring, and a fixed pipe fixed at one end of the first external thread pipe. On one side of the water inlet mechanism, there is a positioning ring fixed on the inner wall of the T-shaped pipe, and on one side of the positioning ring, there is a filter element. The tail end of the filter element is connected with an installation mechanism, and the installation mechanism includes a cover plate, a second external thread pipe fixed on the outer wall of one side of the cover plate, a connecting pipe fixed on the outer wall of one side of the cover plate, a connecting rod inserted into the connecting pipe, a pressing block fixed at one end of the connecting rod, and a telescopic spring connected between the pressing block and the cover plate.

[0007] Close the pipeline valve at one end of the water inlet mechanism. By rotating the cover plate, the second external thread pipe rotates in the T-shaped pipe, so that the whole installation mechanism moves away from the T-shaped pipe. Use the pressing block to pull out the filter element from the other end of the T-shaped pipe. After taking out the filter element for cleaning, insert the filter element back into the other end of the T-shaped pipe, and screw the installation mechanism with the T-shaped pipe. Through the elastic expansion and contraction of the telescopic spring, one end of the filter element abuts against the positioning ring, completing the disassembly, assembly and cleaning of the filter element.

[0008] Preferably, threads are provided at both ends of the inner wall of the T-shaped pipe, and the threads form a threaded fit with the first external thread pipe and the second external thread pipe.

[0009] The water inlet mechanism and the installation mechanism are connected to both ends of the T-shaped pipe by screwing with the first external threaded pipe and the second external threaded pipe through the threaded openings provided.

[0010] Preferably, sealing rings are bonded to the outer walls on both sides of the positioning ring, and both the first external threaded pipe and the filter element form a sealed fit with the positioning ring through the sealing rings.

[0011] The first external threaded pipe and the filter element are abutted against both sides of the positioning ring through the sealing rings.

[0012] Preferably, the outer diameter of the fixed pipe is smaller than the inner diameter of the positioning ring, and the outer diameter of the fixed pipe is adapted to the inner diameter of the filter element.

[0013] The fixed pipe is inserted into the positioning ring and is inserted into one end of the filter element.

[0014] Preferably, the outer diameter of the filter element is smaller than the inner diameter of the T-shaped pipe, and the tail end of the filter element is engaged with the pressing block.

[0015] After the fluid passes through the filter element and is filtered and screened, it enters the T-shaped pipe and is discharged from the bottom end.

[0016] Preferably, the telescopic spring is sleeved and movable on the outer walls of the connecting pipe and the connecting rod.

[0017] Through the elastic expansion and contraction of the telescopic spring, one end of the filter element is abutted against the positioning ring.

[0018] The beneficial effects of the present utility model are as follows:

[0019] By closing the pipeline valve at one end of the water inlet mechanism, rotating the cover plate, rotating the second external threaded pipe in the T-shaped pipe, moving the installation mechanism away from the T-shaped pipe as a whole, pulling out the filter element from the other end of the T-shaped pipe by using the pressing block, taking out the filter element for cleaning, then inserting the filter element back into the other end of the T-shaped pipe, screwing the installation mechanism with the T-shaped pipe, and through the elastic expansion and contraction of the telescopic spring, making one end of the filter element abut against the positioning ring, the disassembly, assembly and cleaning of the filter element are completed, effectively solving the problems in the prior art that the structure of the traditional T-shaped filter is complex, the disassembly of the filter element is inconvenient, and the maintenance is difficult.
