Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a detachable T-type filter. Background Technology

[0002] T-type filters are small devices that remove small amounts of solid particles from liquids, protecting the normal operation of equipment. When fluid enters the filter cartridge containing a filter screen of a certain size, impurities are blocked, while the clean filtrate is discharged from the filter outlet.

[0003] A T-type filter mainly consists of a T-tube, a sealing cap, and a filter cartridge. When cleaning is required, the connection between the sealing cap and the T-tube must be disconnected, and then the filter cartridge can be removed from the T-tube, cleaned, and reinstalled. For example, patent document CN219355512U provides a T-type filter. This device adjusts the position of the filter cartridge by rotating a screw, thereby ensuring the filter cartridge and the conical cylinder fit together. Furthermore, the conical cylinder is made of rubber, providing better sealing performance between the filter cartridge and the conical cylinder, preventing moisture from flowing out between them.

[0004] Currently, most existing sealing caps and T-tubes use flange connections, which makes disassembly and installation cumbersome and delays work efficiency. Therefore, there is an urgent need for a detachable T-tube filter to solve these problems. Utility Model Content

[0005] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0006] Specifically, the technical problem to be solved by this utility model is to provide a detachable T-type filter to solve the problem that the existing sealing cover and T-type tube are mostly connected by flange, which makes the operation more complicated during disassembly and installation and delays work efficiency.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] A detachable T-type filter includes a T-shaped tube and a filter cartridge, and also includes a sealing plate. The sealing plate is connected to the filter cartridge via a connecting rod. A drive limiting mechanism is installed on the sealing plate. A positioning element is inserted into one end of the T-shaped tube, and the drive limiting mechanism is inserted into the positioning element.

[0009] The drive limiting mechanism includes a drive plate that is rotatably connected to the sealing plate. A spiral strip is fixedly connected to one side of the drive plate. Multiple limiting blocks are slidably connected to the spiral strip. The positioning component includes multiple positioning rods. The limiting blocks and positioning rods are inserted into each other.

[0010] As an improved technical solution, the limiting block is slidably engaged with the groove opened on the sealing plate, and the limiting block is provided with an arc-shaped groove adapted to the spiral strip.

[0011] As an improved technical solution, the positioning component includes two semi-circular arc-shaped plates, which abut against one end of the T-shaped tube, and a plurality of positioning rods are distributed at equal intervals on the two arc-shaped plates.

[0012] As an improved technical solution, one end of the positioning rod is fixed with an external thread, which is threadedly connected to a threaded seat fixed on the arc plate. The other end of the positioning rod passes through the T-shaped tube and the sealing plate and has a positioning hole. The limiting block is inserted into the positioning hole.

[0013] As an improved technical solution, a rotating shaft is fixedly connected to the drive plate, the rotating shaft is rotatably connected to the sealing plate, and a handle is slidably connected to the rotating shaft.

[0014] As an improved technical solution, the handle is elastically connected to the rotating shaft by a spring, and both ends of the handle are fixedly connected to positioning plates. Multiple positioning strips are fixedly provided at the edge of the sealing plate, and the positioning plates and positioning strips are inserted into each other.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are:

[0016] 1. This utility model uses a spiral strip to drive each limiting block to expand or contract synchronously on the sealing plate when the drive plate is rotated, so that the limiting block can engage or disengage with the corresponding positioning rod, thereby achieving a quick sealing connection or disconnection between the sealing plate and the T-tube. The operation is simple and helps to improve work efficiency.

[0017] 2. When the handle is not subjected to external force, the spring drives the limiting plate on the handle to engage with the positioning strip. At this time, the handle cannot rotate, thus limiting the rotation of the drive plate. This helps to further improve the stability when the limiting block and the positioning rod are connected, and ensures the sealing between the sealing plate and the T-tube.

[0029] like Figure 1-4 As shown in the figure, this embodiment provides a detachable T-type filter. The detachable T-type filter includes a T-shaped tube 1 and a filter cartridge 2, and also includes a sealing plate 3. The sealing plate 3 is connected to the filter cartridge 2 through a connecting rod. A drive limiting mechanism 4 is installed on the sealing plate 3. A positioning element 5 is inserted and cooperated with one end of the T-shaped tube 1. The drive limiting mechanism 4 and the positioning element 5 are inserted and cooperated.

[0030] The drive limiting mechanism 4 includes a drive plate 401 that is rotatably connected to the sealing plate 3. A spiral strip 402 is fixedly connected to one side of the drive plate 401. Multiple limiting blocks 403 are slidably connected on the spiral strip 402. The positioning component 5 includes multiple positioning rods 502. The limiting blocks 403 and the positioning rods 502 are inserted into each other.

[0031] In the above technical solution, the sealing plate 3 is attached to one end of the T-tube 1. The positioning rod 502 passes through the flange through hole of the T-tube 1 and then through the sealing plate 3 again. When the drive plate 401 is rotated, the spiral strip 402 and the limiting block 403 cooperate to drive the limiting block 403 to slide outward. The limiting block 403 is inserted into the positioning rod 502, so that the sealing plate 3 is sealed and connected to the end of the T-tube 1. When the drive plate 401 is rotated in the opposite direction, the limiting block 403 is disconnected from the fixing rod 502, and the sealing plate 3 can be quickly removed from the end of the T-tube 1.

[0032] The limiting block 403 slides in a groove on the sealing plate 3, and the limiting block 403 has an arc groove 404 that matches the spiral strip 402. When the spiral strip 402 rotates, it slides in a groove with the arc groove 404, which can drive the limiting block 403 to slide straight in the groove, so as to connect or disconnect with the positioning rod 502.

[0033] The positioning component 5 includes two semi-circular arc-shaped plates 501, which abut against one end of the T-shaped tube 1, and multiple positioning rods 502 are evenly distributed on the two arc-shaped plates 501.

[0034] In the above technical solution, the arc plate 501 is located on the side of the T-tube 1 away from the sealing plate 3 and fits against the flange at that location to limit the positioning rod 502. By using the insertion and cooperation of the limiting block 403 and the positioning rod 502, the sealing plate 3 can be tightly attached to the port of the T-tube 1 to achieve sealing.

[0035] Understandably, a rubber sealing gasket is fixed on the side of the sealing plate 3 facing the T-tube 1 to improve the sealing performance during connection.

[0036] One end of the positioning rod 502 is fixed with an external thread 503, which is threadedly connected to the threaded seat 504 fixed on the arc plate 501. The other end of the positioning rod 502 passes through the T-tube 1 and the sealing plate 3 and has a positioning hole. The limiting block 403 is inserted into the positioning hole. The external thread 503 and the threaded seat 504 are inserted into each other, so that the positioning rod 502 and the arc plate 501 are modularly connected, which improves the convenience of later maintenance.

[0037] A rotating shaft 405 is fixedly connected to the drive plate 401. The rotating shaft 405 is rotatably connected to the sealing plate 3. A handle 406 is slidably connected to the rotating shaft 405. When the handle 406 is rotated, the rotating shaft 405 drives the drive plate 405 to rotate synchronously, so that the spiral strip 402 drives the limit block 403 to move.

[0038] The handle 406 is elastically connected to the rotating shaft 405 via a spring 407, and both ends of the handle 406 are fixedly connected to positioning plates 408. Multiple positioning strips 301 are fixedly provided at the edge of the sealing plate 3, and the positioning plates 408 and positioning strips 301 are inserted and engaged.

[0039] In the above technical solution, the positioning strips 301 are arranged in a ring with equal spacing. The positioning plate 408 has a positioning groove on the side facing the sealing plate 3 that matches the positioning strips 3. The spring 407 drives the handle 406 to move towards the sealing plate 3, so that the positioning plate 408 is inserted into the positioning strips 301. At this time, the handle 406 is restricted from rotation, so that the drive plate 401 cannot rotate, ensuring the connection stability between the limit block 403 and the positioning rod 502.

[0040] In use, insert the filter cartridge 2 into the T-tube 1 and fit the sealing plate 3 against one end of the T-tube 1. Fit the arc plate 501 against the flange at that end and pass the positioning rod 502 through the through hole of the flange and the through hole of the sealing plate 3. Then move the handle 406 so that the positioning plate 408 is not connected to the positioning strip 301. Then rotate the handle 406 to drive the drive plate 401 to rotate. The spiral strip 402 drives each limiting block 403 to move outward synchronously. The limiting block 403 passes into the positioning hole of the fixing rod 502 and abuts against it, so that the limiting block 403 drives the sealing plate 3 to fit tightly against the end of the T-tube 1, thus achieving a sealed connection.

[0041] When the handle 406 is rotated in the opposite direction, each limit block 403 can be moved inward synchronously. The limit block 403 is disconnected from the positioning rod 502, and the sealing plate 3 can be disconnected from the T-tube 1, so that the filter cartridge 2 can be taken out for cleaning.

[0042] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
