DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] The utility model provides a kind of rigid polyurethane filter cartridge, as shown in Figure 1 、 Figure 2 And Figure 3 It includes support 1, first connecting end 6 fixedly installed on one end of support 1, second connecting end 7 fixedly installed on the other end of support 1, top cover 2 movably installed on first connecting end 6 and bottom cover 3 movably installed on second connecting end 7, placing groove 11 is formed in bottom cover 3, protective bag 12 is arranged in the inside of placing groove 11, one end of protective bag 12 is fixedly connected to the bottom inner wall of placing groove 11, the other end of protective bag 12 is fixedly connected with connecting ring 13, the side of connecting ring 13 close to protective bag 12 is attached to the side of bottom cover 3 close to second connecting end 7.

[0025] The side surface of support 1 is sleeved with filter material 4, one end of filter material 4 is attached to the side of top cover 2 close to first connecting end 6, the other end of filter material 4 is attached to the side of bottom cover 3 close to second connecting end 7, protective band 5 is movably connected to the side surface of filter material 4

[0026] When the filter cartridge is used, it needs to be installed in the inside of dust removal machine, dust removal machine can suck the air with dust and particulate matter into its inside, the air with dust and particulate matter comes to the inside of dust removal machine and will have direct contact with filter material 4, filter material 4 is made of polyurethane material, this material has good oil resistance, acid and alkali resistance, high temperature resistance, high strength and wear resistance, wrinkle design can increase the filter area of filter cartridge and improve the filtering efficiency, to remove dust and particulate matter in air, protective band 5 is made of elastic material, which can stably fix filter material 4 on support 1.

[0027] The protective bag 12 can be retracted in the placing groove 11. When the dust and particles adsorbed on the surface of the filter material 4 are cleaned, the protective bag 12 can be unfolded by lifting the connecting ring 13. The connecting ring 13 is inlaid with a magnet, and the top cover 2 is also inlaid with a magnet. The connecting ring 13 can be fixed on the top cover 2 by the adsorption force of the magnet, and at the same time, the protective bag 12 can completely wrap the filter material 4, thereby reducing the possibility of dust and particles falling into the dust removal machine and falling onto the ground. At this time, when the dust and particles adsorbed on the surface of the filter material 4 are cleaned, the dust and particles will fall into the placing groove 11 on the bottom cover 3, and then the bottom cover 3 is detached from the support 1 for processing the dust and particles.

[0028] Further, in order to enable the bottom cover 3 to be connected with the support 1, as shown in Figure 2 , Figure 3 and Figure 4 , the bottom cover 3 is provided with a first insertion slot 9 matched with the second connecting end 7, the second connecting end 7 is fixedly connected with a clamping block 8, the bottom cover 3 is provided with an L-shaped clamping slot 10, and the side of the bottom cover 3 away from the second connecting end 7 is fixedly connected with a handle 17.

[0029] When the bottom cover 3 is connected with the support 1, first, the second connecting end 7 on the support 1 needs to be aligned with the first insertion slot 9 on the bottom cover 3, and the clamping block 8 needs to be aligned with the L-shaped clamping slot 10. Then, the bottom cover 3 is moved so that the second connecting end 7 and the clamping block 8 are respectively inserted into the first insertion slot 9 and the L-shaped clamping slot 10. When the clamping block 8 comes into contact with the inner wall of the L-shaped clamping slot 10, the bottom cover 3 is rotated by the handle 17 so that the clamping block 8 continues to move in the L-shaped clamping slot 10 for a distance. At this time, the inner wall of the L-shaped clamping slot 10 fixes the clamping block 8, thereby connecting the bottom cover 3 with the support 1.

[0030] Further, in order to enable the top cover 2 to be connected with the support 1, as shown in Figure 1 , Figure 2 and Figure 5 , the top cover 2 is provided with a second insertion slot 14 matched with the first connecting end 6.

[0031] When the top cover 2 is connected with the support 1, the first connecting end 6 of the support 1 needs to be aligned with the second insertion slot 14 on the top cover 2. The first connecting end 6 is provided with a thread, and the inner wall of the second insertion slot 14 is provided with a thread matched with the first connecting end 6. Then, the top cover 2 is rotated, so that the top cover 2 is connected with the support 1.

[0032] It should be noted that, in order to improve the stability when the bottom cover 3 is connected with the support 1, as shown in Figure 2 , Figure 3 and Figure 4As shown, a pressure plate 16 is slidably connected inside the first slot 9. One side of the pressure plate 16 is in contact with the side of the second connecting end 7 away from the bracket 1. A spring 15 is provided inside the first slot 9. One end of the spring 15 is fixedly connected to the bottom inner wall of the first slot 9, and the other end of the spring 15 is fixedly connected to the side of the pressure plate 16 away from the second connecting end 7.

[0033] Multiple springs 15 are provided, and the multiple springs 15 are distributed in a ring array.

[0034] When the bottom cover 3 is connected to the bracket 1, the second connecting end 7 will contact the pressure plate 16 when it is inserted into the first slot 9, and will press the pressure plate 16, causing the pressure plate 16 to slide inside the first slot 9. While the pressure plate 16 is sliding, it will compress the spring 15. After the bottom cover 3 is connected to the bracket 1, the pressure plate 16 can be pushed by the spring 15, so that the pressure plate 16 is in close contact with the second connecting end 7. The setting of the spring 15 driving the pressure plate 16 to push the second connecting end 7, combined with the friction between the surface of the pressure plate 16 and the surface of the second connecting end 7, can make the bottom cover 3 stably fixed on the bracket 1. The multiple springs 15 are evenly distributed, which can improve the load-bearing capacity and stability of the pressure plate 16, and can also more effectively distribute the load, reduce the stress concentration of a single spring 15, thereby extending the service life of the spring 15.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
