Description

Technical Field

[0001] This utility model relates to the technical field of connection methods for novel slurry filtering devices, and in particular to a novel slurry filtering device. Background Technology

[0002] Existing technology connects pipes and filters using traditional pipe fittings. However, since the pipes are in a fixed position, and traditional pipe fittings require moving both ends of the connection during installation, the pipes also need to be moved, making disassembly and replacement inconvenient.

[0003] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content

[0004] A novel slurry filtration device includes a filter body with filter tube connectors at both ends, and slurry pipes respectively connected to the filter tube connectors. The slurry pipes are fixed in position. The device also includes a quick connector connecting the filter tube connectors and the slurry pipes. The quick connector has a tube section that can extend and retract along the axial direction and remains sealed at the moving part during extension and retraction. After being compressed, the quick connector extends between the slurry pipes and the filter tube connectors, and after being coaxially aligned with the slurry pipes, it returns to its original position, thereby connecting with the slurry pipes and the filter tube connectors and sealing the connection.

[0005] Preferably, the quick connector includes a supporting connecting sleeve and telescopic connectors inserted at both ends of the supporting connecting sleeve. A sealing ring is embedded in the inner end of the supporting connecting sleeve, and a spring is also provided in the supporting connecting sleeve to open the two telescopic connectors. Manually pressing the telescopic connectors shortens the total length of the quick connector for easy installation.

[0006] Preferably, a tail ring is fixedly provided at the tail end of the telescopic pipe joint, the end of the spring abuts against the tail ring, and when the telescopic pipe joint is fully extended, the tail ring is pressed against the sealing ring under the pressure of the spring, thereby further improving the sealing effect.

[0007] Preferably, a rubber end is fixedly provided at the outer end of the telescopic pipe joint, and a through hole with the same diameter as the inner hole of the telescopic pipe joint is provided in the middle of the rubber end. The rubber end is used to abut against the slurry pipe or the filter body.

[0008] Preferably, a stepped hole is provided at the inner end of the telescopic pipe joint, and an embedded connecting pipe with both ends inserted into the stepped hole is provided inside the supporting connecting pipe sleeve. The outer wall of the embedded connecting pipe is glued and fixed with a rubber sealing layer for sealing against the inner wall of the telescopic pipe joint.

[0009] Preferably, a support connecting frame is fixedly provided inside the support connecting tube sleeve. The support connecting frame is fixedly connected to the embedded connecting tube to maintain the position of the embedded connecting tube. The two ends of the embedded connecting tube are provided with stepped countersunk holes. The front end of the filter tube connector or the slurry tube is inserted into the stepped countersunk hole at the end of the embedded connecting tube. A sealing gasket is provided at the joint between the slurry tube and the embedded connecting tube for sealing. The inner wall of the telescopic tube connector is also provided with a rubber sealing layer. The telescopic tube connector is interference-fitted with the slurry tube or the filter tube connector.

[0010] The advantages and positive effects of this utility model are:

[0011] It is more suitable for the operating conditions of existing filters, and can be quickly connected via quick connector 13 without displacement or disassembly of slurry pipeline 11, while meeting the requirements of delivery and sealing, making it more convenient and faster.

The position of the slurry pipe 11 is fixed. The device also includes a quick connector 13 connecting the filter pipe connectors 12 and the slurry pipe 11. The quick connector 13 has a pipe section that can extend and retract along the axial direction and remains sealed at the moving part during the extension and retraction process.

A sealing ring 15 is embedded in the inner end of the supporting connecting sleeve 14. A spring 19 is also provided in the supporting connecting sleeve 14 to open the two telescopic connectors 21. Manually pressing the telescopic connectors 21 shortens the total length of the quick connector 13 for easy installation.

[0021] Preferably, a tail ring 16 is fixedly provided at the tail end of the telescopic pipe joint 21, and the end of the spring 19 abuts against the tail ring 16. When the telescopic pipe joint 21 is fully extended, the tail ring 16 is pressed against the sealing ring 15 under the pressure of the spring 19, thereby further improving the sealing effect.

[0022] Preferably, a rubber end 20 is also fixedly provided at the outer end of the telescopic pipe joint 21. The rubber end 20 has a through hole in the middle that is coaxial with the inner hole of the telescopic pipe joint 21 and has the same diameter. The rubber end 20 is used to abut against the slurry pipe 11 or the filter body 10.

[0023] Preferably, a stepped hole is provided at the inner end of the telescopic pipe joint 21, and an embedded connecting pipe 18 with both ends inserted into the stepped hole is provided in the supporting connecting pipe sleeve 14. The outer wall of the embedded connecting pipe 18 is glued and fixed with a rubber sealing layer for sealing against the inner wall of the telescopic pipe joint 21.

[0025] It should be noted that the elastic force of the spring 19 is selectable by those skilled in the art. The selection of the spring 19 based on the delivery pressure of the slurry pipeline 11 should ensure that all sealing positions are completely sealed and stable after the quick connector 13 is unfolded.
