[0002] Polyurethane resin, as a high-performance polymer material, is widely used in many fields such as foam plastics, coatings, adhesives, elastomers, and sealing materials due to its good mechanical properties, chemical resistance, adhesion, and molding flexibility. The performance of polyurethane resin is closely related to the purity of its main component. In the processing of polyurethane resin main components, the filtration process is a key step to ensure product quality.

[0003] As shown in the reference case "A Filter for Polyurethane Adhesive Production" (Publication No. CN218687079U), it includes a collection shell, with a drainage funnel fixedly connected to the bottom of the collection shell, and multiple support legs fixedly connected to the bottom of the outer wall of the collection shell. This utility model, by designing a filter barrel in the filtration mechanism, allows for continuous feeding while the filter barrel rotates to complete filtration, thus improving filtration efficiency and ensuring continuous feeding of polyurethane adhesive.

[0004] However, when using the above-mentioned device, the filter barrel has a sealed structure at both the top and bottom, making it difficult to remove impurities from the filter barrel, which affects its use. Furthermore, when removing the filter barrel, since the motor is located on top, the motor and the cross-shaped fixing plate need to be removed together first, making installation and disassembly quite troublesome. Utility Model Content

[0005] Therefore, it is necessary to provide a filter for processing polyurethane resin main agent to address the problems of difficulty in removing impurities from the filter cartridge and the cumbersome installation and disassembly.

[0007] In one embodiment, both the connecting cover and the limiting cover are fixedly connected to the top of a lifting lug, and the diameter of the feed pipe is set to correspond to the inner ring of the connecting bearing.

[0008] In one embodiment, both the collection housing and the filter cylinder are arranged in an upper column and lower cone shape, and the collection housing and the filter cylinder are arranged on the same axis, with a gap between the inner wall of the collection housing and the outer wall of the filter cylinder.

[0009] In one embodiment, the collection housing and the filter cylinder are further provided with a driving mechanism, the driving mechanism including a motor fixedly installed at the bottom of the collection housing, a limit block fixedly connected to the output shaft end of the motor, and a limit groove corresponding to the limit block being opened at the bottom of the filter cylinder.

[0010] In one embodiment, a conical block is fixedly connected to the lower part of the filter cylinder, and the diameter of the conical block is larger than the diameter of the motor.

[0011] In one embodiment, a discharge port is provided at the outer part of the bottom of the collecting housing, and the motor is located at the center of the bottom of the collecting housing.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined with Figure 1 - Figure 5 This invention describes a filter for processing polyurethane resin main components.

[0020] In one embodiment, a filter for processing polyurethane resin main agent includes: a collection housing 100, with a filter cylinder 200 rotatably connected inside the collection housing 100; and a maintenance mechanism 300 disposed on the collection housing 100 and the filter cylinder 200. The maintenance mechanism 300 includes a fixing ring 310 fixedly connected to the top of the filter cylinder 200, a connecting cover 320 fixedly connected to the top of the fixing ring 310 by bolts, a limit cover 330 fixedly connected to the top of the collection housing 100 by bolts, a feed pipe fixedly connected to the top of the connecting cover 320, a through hole opened on the top of the limit cover 330, a connecting bearing 350 fixedly connected inside the through hole, and the feed pipe passing through the inner wall of the connecting bearing 350.

[0021] like Figure 2 , Figure 3 and Figure 4As shown, both the connecting cover 320 and the limiting cover 330 are fixedly connected to the top with lifting lugs 340, and the diameter of the feed pipe corresponds to the inner ring of the connecting bearing 350. Both the collecting housing 100 and the filter cylinder 200 are arranged in an upper column and lower cone shape, and are coaxially aligned, with a gap between the inner wall of the collecting housing 100 and the outer wall of the filter cylinder 200. The cylinder wall of the filter cylinder 200 has a porous mesh structure, and the outer wall of the cylindrical section of the collecting housing 100 is provided with an observation window.

[0022] In this embodiment, when it is necessary to clean impurities or clean the filter cylinder 200, the bolts connecting the limiting cover 330 and the collecting housing 100 can be disassembled with the assistance of the lifting lug 340 to quickly remove the filter cylinder 200. The bolts connecting the connecting cover 320 and the fixing ring 310 can be disassembled to quickly open the filter cylinder 200 and clean the internal impurities. The connecting bearing 350 is used to limit the feed pipe, cooperating with the limiting block 420 to ensure the verticality of the filter cylinder 200 and its stability during rotation. The fixing ring 310 and the connecting cover 320 are connected by high-strength bolts, which not only ensures a stable connection and can withstand the radial force generated when the filter cylinder 200 rotates, but also facilitates disassembly. The connecting bearing 350 is a high-precision bearing, with its outer ring interference-fitted with the through hole of the limiting cover 330, and the feed pipe precisely fitted with the inner ring of the connecting bearing 350, avoiding shaking and offset during the filtration process and ensuring the stability of the filter cylinder 200 during rotation.

[0023] like Figure 1 , Figure 2 and Figure 5 As shown, a drive mechanism 400 is also provided on the collection housing 100 and the filter cylinder 200. The drive mechanism 400 includes a motor 410 fixedly installed at the bottom of the collection housing 100. A limit block 420 is fixedly connected to the output shaft end of the motor 410. A limit groove corresponding to the limit block 420 is opened at the bottom of the filter cylinder 200. A conical block 430 is fixedly connected to the lower part of the interior of the filter cylinder 200. The diameter of the conical block 430 is larger than the diameter of the motor 410. A discharge port is opened at the outer part of the bottom of the collection housing 100. The motor 410 is located at the center of the bottom of the collection housing 100. Several stirring blades are evenly distributed on the outer surface of the conical block 430. The stirring blades are arranged along the generatrix of the conical block 430.

[0024] In this embodiment, when filtering the polyurethane resin main agent, the motor 410 starts, and through the cooperation of the limiting block 420 and the bottom limiting groove of the filter cylinder 200, it drives the filter cylinder 200 to rotate stably within the collection housing 100. As the cylinder rotates, the stirring blades outside the conical block 430 reduce impurity blockage and improve the contact efficiency between the main agent and the filter screen, ensuring continuous filtration. The diameter of the conical block 430 is larger than the diameter of the motor 410, preventing the main agent from directly impacting the output shaft and connecting parts of the motor 410, thus extending the service life of the motor 410. The discharge port at the bottom of the collection housing 100 is located on the outer side, smoothly transitioning with the lower conical section of the collection housing 100, facilitating the smooth discharge of the filtered main agent, reducing material residue within the collection housing 100, and preventing contact between the main agent and the motor 410. The conical block 430 inside the filter cylinder 200 is made of wear-resistant and corrosion-resistant stainless steel. Its conical structure corresponds to the lower conical section of the filter cylinder 200, which can smoothly guide the main agent entering the bottom of the filter cylinder 200 to the cylinder wall, avoiding the accumulation of the main agent at the bottom and improving the filtration effect.

[0025] Working principle: The polyurethane resin main agent enters the filter cylinder 200 through the feed pipe. At this time, the motor 410 of the drive mechanism 400 starts and drives the filter cylinder 200 to rotate around the axis through the limit block 420. Under the action of centrifugal force, the main agent flows towards the porous mesh wall of the filter cylinder 200. Particulate impurities, gel blocks, etc. are trapped by the cylinder wall, and the pure main agent passes through the cylinder wall into the gap between the collection shell 100 and the filter cylinder 200.

[0026] During filtration, the stirring blades outside the conical block 430 rotate with the cylinder, continuously agitating the material to prevent impurities from accumulating on the cylinder wall surface and ensuring stable filtration efficiency. Operators can monitor the filtrate status through the observation window on the outer wall of the collection shell 100. The filtered main agent flows along the conical section and guide channel on the inner wall of the collection shell 100 and is finally discharged from the bottom discharge port.

[0027] When cleaning impurities or maintaining the equipment is required, turn off the motor 410. Use the lifting lug 340 to assisted in removing the fixing bolts of the connecting cover 320 and the limit cover 330 to remove the filter cylinder 200. After removing the connecting cover 320, the filter cylinder 200 can be cleaned. After maintenance, reassemble to resume operation. This eliminates the need to disassemble core components such as the motor 410, effectively reducing downtime.

[0028] It should be noted that the motor 410, filter cylinder 200, connecting bearing 350, and lifting lug 340 mentioned above are all components with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the motor 410 can be powered by mains power. The specific power supply method can be selected according to the situation, which will not be elaborated here.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
