[0025] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0026] A preferred embodiment of the impurity filtering rotary joint provided by the utility model is as follows: Figures 1 to 5 Shown: An impurity filtering rotary joint, comprising:

[0027] Rotating sleeve 1;

[0028] The connecting pipe 2 is arranged at the right end of the rotating sleeve 1. A mounting groove 8 is provided on the left side of the connecting pipe 2. A filter plate 6 is clamped on the inner wall of the mounting groove 8.

[0029] The right end of the rotating sleeve 1 is clamped in the mounting groove 8 opened on the left side of the connecting pipe 2 and is in contact with the filter plate 6. The outer wall of the right end of the rotating sleeve 1 is slidably sleeved with a sealing ring 7. The outer wall of the sealing ring 7 is slidably arranged with the inner wall of the mounting groove 8, and the right side of the sealing ring 7 is fixedly installed with the left side of the filter plate 6. The sealing ring 7 can enhance the sealing performance of the clamping point between the rotating sleeve 1 and the connecting pipe 2.

[0030] The inner wall of the fixing ring 3 is fixedly installed with the outer wall of the left end of the connecting pipe 2. A clamping rod 4 is fixedly installed on the left side of the fixing ring 3. A rectangular groove is set at the bottom of the right end of the clamping rod 4, and the right end of the clamping rod 4 is made of rubber material, which is convenient for pushing the clamping rod 4 upward. The convex position of the left end of the clamping rod 4 is clamped with the clamping groove 5 opened on the outer wall of the rotating sleeve 1.

[0031] The outer wall of the rotating sleeve 1 is fixedly sleeved with a mounting ring 10, and a rubber tube 9 is fixedly installed on the side of the mounting ring 10. The right end of the rubber tube 9 is slidably sleeved on the outer wall of the clamping rod 4, and the left end of the rubber tube 9 has a corrugated setting and has telescopic performance;

[0032] A spring 12 is sleeved on the outer wall of the left end of the rubber tube 9, and the inner wall of the right end of the spring 12 is fixedly installed to the outer wall of the rubber tube 9, and the left end of the spring 12 is fixedly installed to the right side surface of the mounting ring 10. The installed spring 12 can prevent the left end of the rubber tube 9 from sliding and retracting easily, and the spring 12 will not affect the retraction and expansion of the rubber tube 9 when force is applied. An auxiliary ring 11 is fixedly installed on the outer wall of the left end of the rubber tube 9 to facilitate pushing the rubber tube 9 to retract and expand it.

[0033] In the specific implementation process, when the filter plate 6 needs to be cleaned, first, the left end of the rubber tube 9 is compressed by pushing the auxiliary ring 11 until the rubber tube 9 is no longer in contact with the clamping rod 4. At this time, the clamping rod 4 is pushed upward to disengage the left end of the clamping rod 4 from the clamping groove 5, and then the rotating sleeve 1 is extracted, and then the filter plate 6 can be taken out for cleaning.

[0034] The above description is only an illustrative specific implementation method of the utility model, and is not intended to limit the scope of the utility model. Any equivalent changes and modifications made by any technician in this field without departing from the concept and principle of the utility model should fall within the scope of protection of the utility model. It should also be noted that the various components of the utility model are not limited to the above-mentioned overall application. The various technical features described in the specification of the utility model can be selected for use alone or in combination according to actual needs. Therefore, the utility model should naturally cover other combinations and specific applications related to the utility model points of this case.
