Description

Technical Field

[0001] The utility model belongs to the technical field of filters, and particularly relates to a basket filter which is convenient for cleaning a filter cartridge. Background Technique

[0002] The basket filter is one of the most common devices in filters. It mainly consists of a main pipe, a filter basket and a flange. An inlet pipe and an outlet pipe are also arranged on the main pipe. The inlet pipe is arranged above the filter basket, and the outlet pipe is arranged outside the filter basket. Thus, the water entering the main pipe through the inlet pipe will first flow into the filter basket. After being filtered by the filter basket, it will escape to the outside through the filter holes, and then flow out through the outlet pipe on the main pipe, forming a complete filtering process.

[0003] A Chinese patent application (or patent) with the publication number of CN221287131U discloses a basket filter, including a main pipe. A flange cover is arranged on the main pipe. A telescopic column is fixedly installed under the flange cover. A return spring is sleeved on the telescopic column. A connecting snap ring is fixedly installed on the inner wall of the main pipe. A filter basket is arranged in the main pipe. The filter basket cooperates with the connecting snap ring. A handle is fixedly installed on the filter basket. An inlet pipe is fixedly installed on one side of the main pipe and above the connecting snap ring. A discharge pipe is fixedly installed on the other side of the main pipe and below the connecting snap ring. The flange cover is fixed on the main pipe through bolts. The return spring will provide a certain thrust to the limit gasket. The limit gasket will squeeze the handle downward under the thrust. The handle will drive the filter basket to move downward, so that the clamping edge fits on the connecting snap ring. An O-shaped rubber ring can be relied on to ensure the tightness of the seal and avoid the occurrence of penetration due to gaps.

[0004] For the above-mentioned basket filter, a connecting snap ring is arranged at the inner top end of the main pipe, that is, the main pipe contacts the bottom side wall of the clamping edge at the bottom of the filter basket through the connecting snap ring, and an O-shaped rubber ring for improving the sealing performance is additionally arranged between them. However, when the filter basket is pulled out of the main pipe, the outer wall of the filter basket will contact the inner wall of the connecting snap ring on the main pipe. And some particulate matters are blocked in the filter holes of the filter basket. Then, this part of particulate matters will contact the inner wall of the connecting snap ring until the particulate matters are broken. Then, part of the powder of the particulate matters will fall outside the filter basket through the filter holes, affecting the output water quality. And, when the filter is in use, the water input from the inlet pipe flushes into the filter basket, and the water filtered by the filter basket is output through the outlet pipe. In this process, because the filter basket receives the impact of high-pressure water for a long time, and a sealing ring is additionally arranged between the filter basket and the main pipe, it will cause the pressure between the filter basket and the main pipe to be too high and it is difficult to take out the filter basket from the main pipe. Therefore, we provide a basket filter which is convenient for cleaning the filter cartridge to solve the problems occurring above. Content of the Utility Model

[0005] The purpose of the present utility model is to provide a basket filter that is convenient for cleaning the filter cartridge. Through the mutual cooperation between the limiting blocks on the inner wall of the outer shell and the top plate welded to the top of the filter cartridge, when the filter cartridge is taken out, the outer wall of the filter cartridge does not rub against the inner wall of the outer shell. By using the support assembly, an elastic sliding fit is achieved between the filter cartridge and the outer shell, facilitating the disassembly and assembly of the filter cartridge, and solving the problems that occur in the above-mentioned basket filter.

[0006] To solve the above technical problems, the present utility model is realized through the following technical solutions:

[0007] The present utility model is a basket filter that is convenient for cleaning the filter cartridge, including an outer shell. A cylinder cover is provided on the top of the outer shell, and a rotating handle is welded on the outer wall of the top of the cylinder cover. The filter cartridge is placed inside the outer shell; a filtering groove is arranged inside the filter cartridge, and limiting blocks are welded on the inner wall of the top of the filtering groove. A top plate is welded on the outer wall of the top of the filter cartridge, and a chute opening is formed on the top plate. The top plate is slidably matched with the limiting blocks on the filter cartridge through the chute opening. An outlet pipe, an inlet pipe, and an auxiliary pipe are also threadedly connected to the outer wall of the outer shell. A support assembly is further installed on the inner wall of the bottom of the filtering groove. A spring is bonded to the bottom plate in the support assembly, and the bottom plate is connected to the abutting plate through the spring. The abutting plate is in contact and cooperation with the outer wall of the bottom of the filter cartridge.

[0008] The present utility model is further provided that a water outlet hole is formed at the bottom of one side outer wall of the outer shell, and a water inlet hole is formed on the upper outer wall of the outer shell on the opposite side of the water outlet hole, and a bottom hole is formed below the water inlet hole.

[0009] The present utility model is further provided that the outer shell is threadedly connected to the outlet pipe through the water outlet hole, and a second flange is installed at the end of the outlet pipe. The outer shell is threadedly connected to the inlet pipe through the water inlet hole, and a first flange is installed at the end of the inlet pipe. The outer shell is threadedly connected to the auxiliary pipe through the bottom hole, and a plug sleeve is sleeved at the end of the auxiliary pipe.

[0010] The present utility model is further provided that a bottom groove is formed inside the bottom of the filtering groove in the outer shell, and the outer shell is cooperatively clamped with the bottom plate in the support assembly through the bottom groove. Side plates are welded on the outer peripheral side wall of the bottom plate.

[0011] The present utility model is further provided that an installation groove is formed on the upper side wall of the bottom plate, and one end of the spring is bonded to the bottom plate through the installation groove. A conical plate is also welded on the upper side wall of the abutting plate.

[0012] The present utility model is further provided that filter holes are formed on the outer peripheral side wall of the filter cartridge, and a conical groove is formed on the outer wall of the bottom of the filter cartridge. The conical groove at the bottom of the filter cartridge is mutually matched with the conical plate on the abutting plate.

[0013] The present utility model is further configured such that the limiting blocks and the chute openings are arranged in one-to-one correspondence, a rubber sleeve is also sleeved on the outer wall of the limiting block, and the limiting block contacts the inner side wall of the chute opening through the rubber sleeve.

[0014] The present utility model is further configured such that there are four limiting blocks in total, and the four limiting blocks are respectively arranged on the inner walls at the four quadrant points of the filtering tank, and a handle rod is welded between the chute openings on the upper side wall of the top plate.

[0015] The present utility model has the following beneficial effects:

[0016] 1. By providing a housing and a filter cartridge, limiting blocks are arranged on the inner wall of the housing, a top plate is welded on the outer wall of the top of the filter cartridge, and chute openings are also provided on the top plate. When the filter cartridge is inserted into the interior of the housing, the chute openings on the top plate cooperate with the limiting blocks on the inner wall of the housing. At the same time, the outer diameter of the top plate is larger than the outer diameter of the filter cartridge. Thus, when the filter cartridge is lifted and taken out, the limiting blocks on the inner wall of the housing are slidably connected with the chute openings. Moreover, the length of the limiting block is greater than the thickness of the top plate, that is, only the top plate will contact the housing and the limiting blocks on its inner wall, and the filter cartridge itself will not contact them. Therefore, it is possible to avoid excessive rubbing between the filter cartridge and the housing during the process of extracting the filter cartridge.

[0017] 2. By providing a support assembly, a support assembly is also arranged at the bottom of the housing. A spring is arranged on the chassis in the support assembly, and the chassis is connected to the abutting plate through the spring. The abutting plate contacts the bottom of the filter cartridge through the frustum plate thereon. When the filter works, due to the impact force of the water flow and the self-weight of the filter cartridge, the spring will be compressed. When the filter does not work, that is, when there is no impact force of the water flow, the spring is less stressed and will have a certain rebound phenomenon. Thus, an elastic sliding fit is achieved between the filter cartridge and the housing, facilitating the disassembly and assembly of the filter cartridge.

[0018] Of course, it is not necessary for any product implementing the present utility model to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS
