Description

Technical Field

[0001] This utility model relates to the technical field of building construction material processing equipment, specifically to a reversible and washable putty powder filter frame. Background Technology

[0002] A reversible and washable putty powder filter screen is a key piece of equipment used in putty powder production or construction to filter impurities. Its main function is to intercept large particles of impurities (such as sand, gravel, and lumpy powder) in the putty powder through the filter screen, ensuring the fineness and uniformity of the finished putty powder, thereby improving the construction quality.

[0003] Traditional putty powder filtration devices mostly use a fixed filter screen structure. After long-term use, the filter screen is prone to clogging due to powder adhesion and impurities, leading to a decrease in filtration efficiency. This requires manual disassembly and cleaning, which is cumbersome and time-consuming. Furthermore, the fixed structure cannot adjust the filtration angle according to actual production needs, making it difficult to adapt to different feed rates or material flow conditions. In addition, traditional devices have insufficient sealing performance, easily causing putty powder leakage during cleaning or disassembly, resulting in material waste and increased workshop cleaning costs. Therefore, there is an urgent need for a putty powder filter screen frame that can be flexibly adjusted in angle, is easy to clean, and has good sealing performance. Utility Model Content

[0004] The purpose of this invention is to provide a reversible and washable putty powder filter frame. Through structural optimization, it solves the problems of inconvenient cleaning, non-adjustable angle, poor sealing and low fixation reliability of traditional filter devices, thereby improving filtration efficiency and ease of operation.

[0005] The technical solution provided by this utility model is a reversible and washable putty powder filter frame, including a frame, a filter frame and a detachable filter module. The frame is rotatably connected to both sides of the filter frame, and the filter module is located at the bottom of the filter frame.

[0006] The filter frame has guide grooves on both sides perpendicular to the connection surface of the frame body. An adjustment plate connected to the filter frame is provided in the guide groove. One side of the adjustment plate is fixed to the position of the guide groove by an adjustment knob.

[0007] The filter module includes a support frame that is spliced ​​to the bottom of the filter frame, and a filter screen that is rotatably installed inside the support frame via a rotating shaft. The filter screen has a filtration accuracy of 80 to 300 mesh.

[0008] As a preferred technical solution of this utility model, the frame includes two side plates arranged opposite to each other and a bottom plate connecting the two side plates. The two sides of the filter frame are rotatably connected to the side plates through connecting columns fitted with bearings.

[0009] In a preferred embodiment of this invention, the side plate is provided with a positioning pin hole below the connecting column, and the filter frame is provided with multiple positioning insertion holes corresponding to the positioning pin holes below the connecting column.
