Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a filtering device for a pre-coating filter. Background Art

[0002] At present, surface pre-coating filtration equipment is suitable for filtering liquids that have very high filtering accuracy requirements on the one hand, but are difficult to filter at the same time. For example, when finishing casting materials, fine abrasive particles will enter the grinding oil. Since fine graphite is dispersed in the grinding powder, it will quickly cause the filter medium to be blocked, and it is difficult for the grinding oil to flow through the filter cake containing such fine particles to complete the filtration, and it is also accompanied by huge pressure loss. In this case, the filtering method of forming the filter cake will consume a lot of energy and is very inefficient, so it is necessary to optimize the filtering device of the pre-coating filter.

[0003] For example, a constant pressure pre-coat filter is disclosed in the Chinese utility model patent with announcement number CN211585611 U. In the above prior art, although the I-shaped disc of the filter assembly has a stirring function to prevent material sedimentation, and the dry residue is automatically discharged intermittently by unloading, and the dry residue and clarified filtrate are discharged from different positions, the filter plate needs to be cleaned and replaced after a long period of filtration. Since the filter cartridge is an integral whole, the filter cartridge needs to be disassembled and opened for replacement to replace the internal filter plate. This replacement not only takes a long time but also requires the filter to be shut down during replacement, affecting the working efficiency of the machine. Therefore, it is necessary to design a filtering device for a pre-coat filter that can quickly clean and replace the filter plate inside the filter cartridge. Utility Model Content

[0004] In order to solve the technical problem that the filter plate inside the filter cartridge is difficult to replace and clean, the utility model provides a filtering device for a pre-coating filter.

[0005] The utility model is implemented by the following technical scheme: a filtering device for a pre-coat filter, comprising a box body, a slag discharge component is installed on one side of the box body, a fixed block is fixedly installed on one side of the slag discharge component, a plurality of filter cartridges are arranged on one side of the fixed block, a filter component for filtering is arranged inside each of the filter cartridges, a replacement component for quickly replacing and cleaning the filter component is arranged on one side of each of the filter components, and a clamping component is arranged on one side of each of the replacement components to prevent vibration from loosening the filter component.

[0006] Through the above technical solution, when the filter plate needs to be replaced, the pressing component is rotated to release the pressing effect on the replacement component, and the replacement component is taken out from the filter cartridge, and the filter plate can also be taken out for cleaning and replacement.

[0007] As a further improvement of the above solution, a plug interface is provided on one side of each filter cartridge, and the filter assembly includes a filter plate arranged inside the filter cartridge and a limiting ring arranged on both sides of the filter plate and fixedly mounted to the inner wall of the filter cartridge.

[0008] Through the above technical solution, after the filter plate is placed into the filter cartridge, it will be clamped and limited by the two limiting rings.

[0009] As a further improvement of the above solution, the replacement assembly includes a mounting ring fixedly mounted on the filter plate and a first sealing plate fixedly mounted on one side of the mounting ring, and the first sealing plate is adapted to the plug interface.

[0010] Through the above technical solution, the filter plate is installed on the installation ring and matched with the first sealing plate, and can be inserted into the plug-in port of the filter cartridge for use.

[0011] As a further improvement of the above solution, a second sealing plate is fixedly installed on one side of the first sealing plate, one side of the second sealing plate is in contact with the outer surface of the filter cartridge, a limiting block is fixedly installed on one side of the second sealing plate, and a clamping groove is provided on one side of the limiting block.

[0012] Through the above technical solution, the second sealing plate cooperates with the first sealing plate to prevent the first sealing plate from leaking.

[0013] As a further improvement of the above scheme, the clamping assembly includes a connecting rod fixedly installed on one side of the fixed block, a connecting plate rotatably mounted on one end of the connecting rod, a clamping plate arranged on one side of the connecting plate, and multiple limiting rods fixedly installed on one side of the clamping plate, one end of each of the limiting rods passes through the connecting plate, and the clamping plate is adapted to the clamping groove.

[0014] Through the above technical solution, the clamping plate is placed in the clamping groove to clamp the limit block to prevent vibration from loosening the filter cartridge seal.

[0015] As a further improvement of the above solution, each of the limit rods is sleeved with a compression spring, one end of which is fixedly mounted to the compression plate and the other end of which is fixedly mounted to the connecting rod.

[0016] Through the above technical solution, the compression spring will always press the compression plate to prevent the seal of the filter cartridge from loosening due to vibration.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model provides a filter assembly, a replacement assembly and a pressing assembly. When the filter plate inside the filter cartridge needs to be replaced or cleaned, the pressing assembly is removed to release the pressing effect of the replacement assembly, and then the pressing assembly is pulled out from the plug-in interface of the filter cartridge. The filter plate on the pressing assembly can be taken out for cleaning or replacement. After completion, the filter plate is mounted on the pressing assembly, reinserted into the filter cartridge and pressed using the pressing assembly. In this way, the filter plate inside the filter cartridge can be quickly replaced and cleaned. BRIEF DESCRIPTION OF THE DRAWINGS
