Description

Technical Field

[0001] This utility model relates to a high-efficiency sealing connector for ceramic membrane filtration devices, and belongs to the technical field of sealing connectors. Background Technology

[0002] Ceramic membrane filtration equipment uses pump pressure as the driving force and relies on the selectivity of the membrane to separate components in a liquid. During the filtration process, the microporous structure on the surface of the ceramic membrane only allows molecules or particles of a specific size to pass through, while retaining other substances, thereby achieving the purposes of separation, concentration, and purification of the liquid.

[0003] Chinese Patent Publication No. (CN 211738347 U) discloses a high-efficiency sealing pipe connector, including a steel pipe connector and a sealing component disposed on the inner wall of a connecting groove. A steel pipe is connected to one side of the steel pipe connector, and a connecting groove for connecting the steel pipe is formed on the inner wall of the steel pipe connector. The sealing component includes a sealing ring, a clamping element, and a sealing ring disposed on the connecting pipe. The sealing ring is fixedly connected to the inner wall of the steel pipe connector. When the steel pipe connector is inserted into the steel pipe connector, the sealing ring is pressed together with the sealing ring. The steel pipe and the steel pipe connector are pressed together by the clamping element. This utility model has the effect of improving the sealing performance between the steel pipe and the steel pipe connector.

[0004] However, during filtration, the material to be filtered needs to be transported by connecting pipes to the filtration equipment. During transport, the pipes are directly fixed with bolts. Over time, gaps can easily appear at the connection points, leading to material leakage and making it inconvenient for operators to work.

[0005] To address this, a high-efficiency sealing connector for ceramic membrane filtration devices is proposed. Utility Model Content

[0006] In view of this, the present invention provides a high-efficiency sealing connector for ceramic membrane filtration devices to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial alternative.

[0007] The technical solution of this utility model is implemented as follows: a high-efficiency sealing connector for a ceramic membrane filter includes a fixed tube, a connecting tube movably connected to the right side of the fixed tube, and connecting mechanisms provided at the top and bottom of the fixed tube. The connecting mechanism includes a telescopic cylinder, a fixing nut, and an extension rod. The inner side of the telescopic cylinder is fixedly connected to the surface of the fixed tube, the left side of the extension rod is fixedly connected to the right side of the telescopic cylinder, and the fixing nut is threadedly connected to the surface of the extension rod.

[0008] More preferably, a limiting plate is fixedly connected to the left side of the connecting pipe, and the left side of the limiting plate extends through to the left side of the fixed pipe.

[0009] More preferably, the surface of the fixed tube is provided with a insertion groove, and the surface of the limiting plate is movably connected to the inside of the insertion groove.

[0010] More preferably, a fixing ring is fitted on the surface of the fixing tube and the connecting tube, a bolt is provided on the right side of the connecting tube, and the left side of the bolt passes through the connecting tube and the fixing ring and extends to the left side of the fixing tube.

[0011] More preferably, both the fixed tube and the connecting tube have threaded holes on their surfaces, and the surface of the bolt is movably connected to the inside of the threaded holes.

[0012] More preferably, a sealing gasket is fixedly connected inside the fixing ring. The sealing gasket is made of rubber, and the surface of the sealing gasket is in contact with the surfaces of the fixing tube and the connecting tube.

[0013] More preferably, there are two connecting mechanisms, which are located at the top and bottom of the fixed tube, respectively.

[0015] I. This utility model uses a connecting mechanism where a telescopic cylinder drives the extension rod to retract, ensuring a stable connection and fixation between the fixed pipe and the connecting pipe. This prevents gaps from appearing at the connection point during use. By setting a limiting plate, the movement direction and stroke of the connecting pipe are restricted during connection, ensuring the normal use of the structure.

[0016] Second, this utility model uses a fixing ring to fix the connection between the fixing pipe and the connecting pipe after docking. By setting a sealing gasket, the sealing performance is further improved during connection, preventing leakage during long-term use.

The connecting mechanism 3 includes a telescopic cylinder 301, a fixing nut 302, and an extension rod 303. The inner side of the telescopic cylinder 301 is fixedly connected to the surface of the fixed tube 1, the left side of the extension rod 303 is fixedly connected to the right side of the telescopic cylinder 301, the fixing nut 302 is threadedly connected to the surface of the extension rod 303, a limiting plate 4 is fixedly connected to the left side of the connecting tube 2, the left side of the limiting plate 4 extends through to the left side of the fixed tube 1, and an insertion groove 5 is provided on the surface of the fixed tube 1. The surface of the limiting plate 4 is movably connected to the inside of the insertion groove 5. There are two connecting mechanisms 3, which are located at the top and bottom of the fixed tube 1, respectively.

[0029] Through the connecting mechanism 3, the telescopic cylinder 301 drives the extension rod 303 to retract, so that the fixed pipe 1 and the connecting pipe 2 are stably connected and fixed, preventing gaps from appearing at the connection during use. By setting the limiting plate 4, the movement direction and stroke of the connecting pipe 2 are restricted when it is connected, ensuring the normal use of the structure.

[0030] Example 2

[0031] like Figure 3-5 As shown, in one embodiment, a fixing ring 6 is fitted on the surface of the fixing pipe 1 and the connecting pipe 2. A bolt 7 is provided on the right side of the connecting pipe 2. The left side of the bolt 7 passes through the connecting pipe 2 and the fixing ring 6 and extends to the left side of the fixing pipe 1. Threaded holes 8 are opened on the surface of both the fixing pipe 1 and the connecting pipe 2. The surface of the bolt 7 is movably connected to the inside of the threaded hole 8. A sealing gasket 9 is fixedly connected inside the fixing ring 6. The sealing gasket 9 is made of rubber, and the surface of the sealing gasket 9 is in contact with the surface of the fixing pipe 1 and the connecting pipe 2.

[0032] The fixing ring 6 is used to fix the connection between the fixing pipe 1 and the connecting pipe 2 after docking, thereby improving the sealing performance of the connection. The sealing gasket 9 is also used to improve the sealing performance during connection and prevent leakage during long-term use.

[0033] When this utility model is in operation: First, the telescopic cylinder 301 is activated, which extends the extension rod 303. The extension rod 303 is then fixed to the extension rod 303 by the fixing nut 302. After that, the telescopic cylinder 301 is activated, which drives the extension rod 303 to move to the left. The limiting plate 4 moves along the trajectory provided by the insertion slot 5 to connect the fixing tube 1 and the connecting tube 2. After the fixing is completed, the fixing ring 6 is inserted and fixed by the bolt 7. This allows the sealing gasket 9 to contact the surfaces of the fixing tube 1 and the connecting tube 2, increasing the sealing at the connection and preventing loosening.
