[0022] The inner filter barrel 201 and the outer filter barrel 1 are both made of polypropylene material, and the connection pipe 103 is provided to evacuate the interior of the outer filter barrel 1 .

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the connection assembly 21 includes a top plate 211 arranged on the top of the inner filter barrel 201, the upper end of the top plate 211 penetrates the mounting ring 102, the bottom of the top plate 211 is fixedly connected with a connection block 212, the surface of the connection block 212 is provided with an external thread, the inner wall of the inner filter barrel 201 is provided with an internal thread, the connection block 212 is threadedly connected with the inner filter barrel 201 through the external thread, the top of the top plate 211 is provided with an injection pipe 2112, the lower end of the injection pipe 2112 penetrates the top plate 211 and the connection block 212 in sequence, and the top of the injection pipe 2112 is provided with a detachable blocking block;

[0024] The forward and reverse rotation of the top plate 211 can drive the connecting block 212 to be installed or separated from the inner filter barrel 201 through the internal thread and the external thread. After the installation is completed, the mixed liquid to be filtered can be added to the interior of the inner filter barrel 201 by removing the blocking block.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the outer edge of the connection block 212 is provided with two receiving cavities, the inner wall of the receiving cavity is slidably connected with a clamping block 216, the inner edge of the mounting ring 102 is provided with a clamping groove 2111 corresponding to the clamping block 216, one side of the clamping block 216 extends to the inside of the adjacent clamping groove 2111, and the bottom of the clamping block 216 close to the clamping groove 2111 is provided with a wedge surface, the other side of the clamping block 216 is fixedly connected with a spring 217, the other end of the spring 217 is fixedly connected to the inner wall of the receiving cavity, and the top plate 2 A pull block 215 is provided at the top of the top plate 11, and a rotating rod 218 is fixedly connected to the bottom of the pull block 215. The lower end of the rotating rod 218 passes through the top plate 211 and is rotatably connected to the inner wall of the top plate 211. A spring 219 is fixedly connected to the surface of the rotating rod 218, and the other end of the spring 219 is fixedly connected to the inner wall of the top plate 211. A connecting rope 2110 is fixedly connected to the side of the clamping block 216 away from the mounting ring 102, and the other end of the connecting rope 2110 is fixedly connected to the surface of the rotating rod 218.

[0026] When the inner filter barrel 201 is connected to the top plate 211 through the connecting block 212, it can be inserted into the inner part of the outer filter barrel 1 through the mounting ring 102. During this process, the surface of the mounting ring 102 can squeeze the wedge surface of the block 216, so that it compresses the spring 217 until the bottom of the inner filter barrel 201 contacts the top surface of the support plate 101 and the top plate 211 cannot be moved down further. At this time, the top plate 211 is rotated until the block 216 corresponds to the slot 2111 and can be inserted into the slot 2111 under the action of the spring 217. The staff can hear the knocking sound of the block 216 and the inner wall of the slot 2111, which indicates that the installation is in place. The position of the inner filter barrel 201 is limited by the mutual cooperation of the block 216 and the slot 2111.

[0030] When the utility model is in use, the blocking block is disassembled and the mixed liquid to be filtered is introduced into the interior of the inner filter barrel 201 through the injection pipe 2112 for filtering treatment. When the impurities collected in the inner filter barrel 201 need to be cleaned, the pull block 215 is rotated, and the rotating rod 218 and the connecting rope 2110 cooperate with each other to drive the clamping block 216 to retract into the interior of the storage chamber, so that the clamping block 216 is separated from the clamping groove 2111, and the inner filter barrel 201 can be quickly taken out to clean the impurities collected inside. In the process of separating the inner filter barrel 201, the inner wall of the inner filter barrel 201 can be cleaned with the cooperation of the connecting rod 213 and the scraper 214, so as to reduce the adhered impurities, facilitate the removal of the collected impurities, reduce the cleaning time of the inner filter barrel 201, and facilitate the subsequent needs After the impurities in the filtered mixed liquid are separated and collected and cleaned, the inner filter barrel 201 is threadedly connected to the connecting block 212 through the cooperation of the internal thread and the external thread, and then inserted into the interior of the outer filter barrel 1 through the mounting ring 102. During this process, the surface of the mounting ring 102 can squeeze the wedge surface of the block 216, so that it compresses the spring 217 until the bottom of the inner filter barrel 201 contacts the top surface of the support plate 101 and the top plate 211 cannot move down further. At this time, the top plate 211 is rotated until the block 216 corresponds to the slot 2111 and can be inserted into the slot 2111 under the action of the spring 217. The staff can hear the knocking sound of the block 216 and the inner wall of the slot 2111, which indicates that the installation is in place. The position of the inner filter barrel 201 is limited by the cooperation of the block 216 and the slot 2111.

[0031] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
