Description

Technical Field

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

[0002] A filter is a device used to separate solid particles from a mixture of solid and liquid. It uses a certain filter medium to retain solid particles on the filter medium and allow the liquid to pass through, thereby achieving the purpose of solid-liquid separation.

[0003] When installing a filter on a liquid pipeline, the filter is often connected to an inlet pipe, a drain pipe and a sewage pipe. In this case, the entire filter needs to be disassembled to replace the filter element inside the filter. When dismantling the pipeline, not only is the operation relatively troublesome, but the sealing and stability of the threaded connection at the pipeline connection will decrease to a certain extent after multiple disassembly and assembly. Therefore, it is necessary to design a filter that can independently remove the filter element. Utility Model Content

[0006] Preferably, the fixing assembly includes a fixing column and a fixing hole, the fixing column is fixed to the side of the filter housing away from the side groove, fixing blocks are installed at both ends of the fixing column, a fixing hole is opened on the side close to the annular rotating plate, and the upper end of the fixing block is inserted into the fixing hole.

[0007] Preferably, telescopic grooves are provided at both ends of the fixed column and at positions corresponding to the fixed block, a telescopic block is slidably connected in the telescopic groove, one end of the fixed block is located in the telescopic groove and fixed on the telescopic block, and a telescopic spring is fixed between the telescopic block and the inner wall of the telescopic groove.

[0008] Preferably, a push-pull block is slidably connected to the outer side of the fixed column, and the outer side of the telescopic block is fixed to the push-pull block.

[0009] Preferably, the sealing sleeve is a semicircular arc structure, and a sealing gasket is fixed at the connection between the periphery and the side groove.

[0010] Preferably, an anti-slip bump is fixed at the middle position of the inner side of the baffle.

[0011] Compared with the prior art, the utility model has the following beneficial technical effects: a detachable sealing sleeve is installed on the side wall of the filter housing. When the filter is disassembled, only the sealing sleeve needs to be removed to replace the filter element. The operation is relatively simple and there is no need to remove the water inlet pipe and the water outlet pipe connector. At the same time, the weakening of the sealing effect caused by multiple disassembly and assembly can be avoided. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Example

[0019] like Figure 1-4As shown, a detachable filter proposed by the utility model comprises a filter housing 1 and a mounting head 2, the mounting head 2 is fixed at the upper end of the filter housing 1, a filter element 11 is installed in the filter housing 1, a sewage pipe 12 is fixed at the bottom of the filter housing 1, an inlet pipe 21 and an outlet pipe 22 are respectively fixed on both sides of the mounting head 2, a side groove 3 is opened in the middle position of the side wall of the filter housing 1, a sealing sleeve 4 is clamped in the side groove 3, an annular rotating plate 5 is rotatably connected at the upper and lower ends of the side groove 3 on the outside of the filter housing 1, a baffle 51 is fixed on the side close to the annular rotating plate 5, and the inner wall of the baffle 51 is against the sealing sleeve 4, a fixing component 6 is arranged on the side of the filter housing 1 away from the side groove 3, the sealing sleeve 4 is a semicircular arc structure, and a sealing pad 41 is fixed at the connection between the periphery and the side groove 3, and an anti-slip protrusion 52 is fixed at the middle position of the inner side of the baffle 51.

[0020] The fixing assembly 6 includes a fixing column 61 and a fixing hole 62. The fixing column 61 is fixed to the side of the filter housing 1 away from the side groove 3. Fixing blocks 63 are installed at both ends of the fixing column 61. A fixing hole 62 is opened on the side close to the annular rotating plate 5. The upper end of the fixing block 63 is inserted into the fixing hole 62. Telescopic grooves 64 are opened at both ends of the fixing column 61 and at positions corresponding to the fixing block 63. A telescopic block 65 is slidably connected in the telescopic groove 64. One end of the fixing block 63 is located in the telescopic groove 64 and is fixed on the telescopic block 65. A telescopic spring 66 is fixed between the telescopic block 65 and the inner wall of the telescopic groove 64. A push-pull block 67 is slidably connected to the outer side of the fixing column 61, and the outer side of the telescopic block 65 is fixed to the push-pull block 67.

[0021] In this embodiment, after the water inlet pipe 21, the water outlet pipe 22 and the sewage pipe 12 are connected to the corresponding pipes, the filter element 11 can be disassembled by removing the sealing sleeve 4, taking out the internal filter element 11, and then installing the sealing sleeve 4 after replacing the filter element 11. In this process, the rotation of the annular rotating plate 5 drives the baffle 51 to rotate around the outer periphery of the filter housing 1. When the baffle 51 rotates to abut against the sealing sleeve 4, the sealing sleeve 4 can be squeezed and fixed in the side groove 3. Conversely, after the sealing sleeve 4 loses the obstruction of the baffle 51, the sealing sleeve 4 can be easily removed. The platform is removed, and when the annular rotating plate 5 rotates to the specified position, the telescopic block 65 is pushed by the telescopic spring 66, which can drive the telescopic block 65 to slide to the outside of the telescopic groove 64, and then the fixed block 63 is pushed out, and finally the end of the fixed block 63 is inserted into the fixing hole 62 to prevent the rotation of the annular rotating plate 5, so as to fix the position of the annular rotating plate 5 and the baffle 51. During the whole process, when the filter element 11 is replaced, there is no need to remove the water inlet pipe 21, the sewage pipe 12 and the water outlet pipe 22. The operation is relatively simple and there is no need to destroy the sealing of the connection.

[0022] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
