The design of the polytetrafluoroethylene coating and the non-woven fabric structure formed by needle punching basalt fiber in the utility model enables the filter cloth body to have a better high-temperature resistance effect when in use.

[0004] In the process of implementing this application, it was found that the technology has the following problems: most of the existing high-temperature resistant industrial filter cloths are designed with a non-woven fabric structure of polytetrafluoroethylene coating and basalt fiber needle-punched to make the filter cloth body have better high-temperature resistance when in use, but the internal metal filter mesh of most industrial filter cloths is prone to softening and deformation during long-term use, resulting in gaps between the metal filter mesh and multiple groups of filter layers, which makes the filter cloth unable to continue to be used, thereby reducing the practicality of the equipment.

[0005] For this reason, a high temperature resistant industrial filter cloth is proposed. Utility Model Content

[0006] The purpose of the utility model is to solve the problem that the internal metal filter screen of most industrial filter cloths is easily softened and deformed during long-term use, resulting in gaps between the metal filter screen and multiple groups of filter layers, which makes the filter cloth unable to continue to be used. The utility model provides a high-temperature resistant industrial filter cloth.

[0007] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0008] A high-temperature resistant industrial filter cloth comprises a U-shaped positioning frame, wherein a filter layer 1 and a filter layer 2 are installed inside the U-shaped positioning frame, grooves are provided on the left and right inner walls of the U-shaped positioning frame, a filter mechanism for adjusting the inner diameter of the filter holes of the industrial filter cloth is installed inside the groove of the U-shaped positioning frame, and a protective mechanism is provided on the side of the filter mechanism away from the U-shaped positioning frame.

[0010] Furthermore, a base fabric is provided on the outer surface of the U-shaped positioning frame.

[0011] Furthermore, the protective mechanism includes a cloth strip and a Velcro hook surface, the cloth strip is sewn on the front side of the base cloth, the side of the cloth strip close to the screw is provided with a Velcro fleece surface, the outer surface of the base cloth close to the screw is provided with a Velcro hook surface, the Velcro hook surface is located on the moving path of the Velcro fleece surface, and the screw is located at the directly lower end of the moving path of the Velcro fleece surface.

[0013] Furthermore, the U-shaped positioning frame is made of metal nickel.

[0014] The beneficial effects of the utility model are as follows:

[0015] 1. The utility model drives the screw to move inside the threaded hole of the fixing plate by rotating the screw, and then the bottom end of the screw is rotatably connected to the inside of the groove of the U-shaped fixing frame, so that the screw synchronously drives the U-shaped fixing frame to move inside the two groups of grooves of the U-shaped positioning frame during the movement, and pushes the U-shaped fixing frame out of the positioning groove at the bottom end of the U-shaped positioning frame, so that the filter mechanism can be disassembled from the inside of the industrial filter cloth, so that the subsequent filter mechanism or the filter layer 1 and the filter layer 2 can be disassembled and replaced during the damage process, thereby reducing the time spent on the subsequent maintenance of the industrial filter cloth, thereby improving the practicality of the device.

[0016] 2.

[0026] like Figures 1 to 4 As shown, a high-temperature resistant industrial filter cloth comprises a U-shaped positioning frame 1, a filter layer 1 3 and a filter layer 2 4 are installed inside the U-shaped positioning frame 1, grooves are provided on the inner walls on the left and right sides of the U-shaped positioning frame 1, a filter mechanism 5 for adjusting the inner diameter of the filter holes of the industrial filter cloth is installed inside the groove of the U-shaped positioning frame 1, and a protective mechanism 6 is provided on the side of the filter mechanism 5 away from the U-shaped positioning frame 1; specifically, the filter mechanism 5 is slidably connected to the two groups of grooves of the U-shaped positioning frame 1 by part of the internal equipment of the filter mechanism 5, so that the filter mechanism 5 can be disassembled from the inside of the industrial filter cloth, so that the subsequent filter mechanism 5 or the filter layer 1 3 and the filter layer 2 4 can be disassembled and replaced during damage, thereby reducing the time spent on the subsequent maintenance of the industrial filter cloth, thereby improving the practicality of the device.

[0027] like Figures 1 to 4 As shown, the filtering mechanism 5 includes a Chinese-shaped fixed frame 501 and a fixed plate 503, the Chinese-shaped fixed frame 501 is slidably connected to the inside of the two groups of grooves of the U-shaped positioning frame 1, a metal filter screen 502 is arranged inside the Chinese-shaped fixed frame 501, the left and right sides of the fixed plate 503 are respectively installed on the opposite sides of the two groups of grooves of the U-shaped positioning frame 1, a threaded hole is provided on the upper surface of the fixed plate 503, a screw 504 is connected to the internal thread of the fixed plate 503, a groove is provided on the side of the Chinese-shaped fixed frame 501 close to the fixed plate 503, the bottom end of the screw 504 is rotatably connected to the inside of the groove of the Chinese-shaped fixed frame 501, a positioning groove is provided at the bottom end of the U-shaped positioning frame 1, and the outer contour of the Chinese-shaped fixed frame 501 is adapted to the inner contour of the positioning groove of the U-shaped positioning frame 1;

[0028] Specifically, after the industrial filter cloth has been used for a long time, the screw 504 is driven to move inside the threaded hole of the fixing plate 503 by rotating the screw 504, and then the bottom end of the screw 504 is rotated and connected to the inside of the groove of the U-shaped fixing frame 501, so that the screw 504 simultaneously drives the U-shaped fixing frame 501 to move inside the two groups of grooves of the U-shaped positioning frame 1 during the movement, and pushes the U-shaped fixing frame 501 out of the positioning groove at the bottom end of the U-shaped positioning frame 1, so that the filter mechanism 5 can be disassembled from the inside of the industrial filter cloth, so that the subsequent filter mechanism 5 or the filter layer 1 3 and the filter layer 2 4 can be disassembled and replaced during the damage process, thereby reducing the time spent on the subsequent maintenance of the industrial filter cloth, thereby improving the practicality of the device.

[0029] like Figure 1 and Figure 2 As shown, a base cloth 2 is provided on the outer surface of the U-shaped positioning frame 1; specifically, the base cloth 2 is wrapped around the outer surface of the U-shaped positioning frame 1 so that the base cloth 2 shields and protects the exposed portion of the U-shaped positioning frame 1, thereby minimizing damage to the U-shaped positioning frame 1 caused by oxidation or collision during daily use; the exposed portion of the U-shaped positioning frame 1 is shielded by the base cloth 2, and the exposed portion of the base cloth 2 is relatively smooth and flat, thereby improving the aesthetics of the industrial filter cloth during use.

[0030] like Figure 1 and Figure 2 As shown, the protective mechanism 6 includes a cloth strip 601 and a Velcro hook surface 603. The cloth strip 601 is sewn on the front side of the base fabric 2. The side of the cloth strip 601 close to the screw 504 is provided with a Velcro fur surface 602. The outer surface of the side of the base fabric 2 close to the screw 504 is provided with a Velcro hook surface 603. The Velcro hook surface 603 is located on the moving path of the Velcro fur surface 602. The screw 504 is located at the lower end of the moving path of the Velcro fur surface 602. Specifically, by rotating the cloth strip 601, the Velcro fur surface 602 is bonded to the side of the Velcro hook surface 603 away from the base fabric 2, and the position of the screw 504 is located at the lower end of the moving path of the Velcro fur surface 602, so that when the cloth strip 601 is bonded to one side of the Velcro hook surface 603, the exposed part of the screw 504 is covered, thereby trying to avoid the subsequent accumulation of excessive dust on the exposed part of the screw 504, which will cause the staff to be unable to normally adjust the position of the movable metal filter 502, thereby reducing the number of times the staff regularly cleans the screw 504.

[0031] like Figure 1 and Figure 2As shown, the front and rear inner walls of the metal filter mesh 502 are respectively in contact with the adjacent sides of the filter layer 1 3 and the filter layer 2 4; specifically, the front and rear inner walls of the metal filter mesh 502 are respectively in contact with the adjacent sides of the filter layer 1 3 and the filter layer 2 4, thereby preventing the subsequent filtered gas or liquid from flowing or floating along the connection between the filter mechanism 5 and the filter layer 1 3 and the filter layer 2 4, thereby preventing the filter mechanism 5 from being able to adjust the filter aperture of the industrial filter cloth during use.

[0032] like Figure 2 As shown, the material of the U-shaped positioning frame 1 is metallic nickel; specifically, metallic nickel has strong corrosion resistance and high temperature resistance, so that the U-shaped positioning frame 1 is not easily corroded, melted and deformed by flowing media and gases during long-term use, thereby increasing the service life of the U-shaped positioning frame 1 and the industrial filter cloth, thereby improving the practicality of the device; the U-shaped positioning frame 1 has strong hardness during use, so that the staff only needs to support the two ends of the industrial filter cloth during the installation of the industrial filter cloth to limit the moving position of the industrial filter cloth, thereby reducing the time spent by subsequent staff in installing the industrial filter cloth.

[0033] In summary, the screw rod 504 is driven to move inside the threaded hole of the fixing plate 503 by rotating the screw rod 504, and then the bottom end of the screw rod 504 is rotated and connected to the inside of the groove of the U-shaped fixing frame 501, so that the screw rod 504 synchronously drives the U-shaped fixing frame 501 to move inside the two groups of grooves of the U-shaped positioning frame 1 during the movement, and the U-shaped fixing frame 501 is pushed out from the positioning groove at the bottom end of the U-shaped positioning frame 1, so that the filter mechanism 5 can be disassembled from the inside of the industrial filter cloth, so that the subsequent filter mechanism 5 or the filter layer 1 3 and the filter layer 2 4 can be disassembled and replaced during the damage process. The replacement can be realized, thereby reducing the time spent on the subsequent maintenance of the industrial filter cloth, thereby improving the practicality of the device; by rotating the cloth strip 601, the Velcro fleece surface 602 is bonded to the side of the Velcro hook surface 603 away from the base cloth 2, and then the screw 504 is located at the lower end of the moving path of the Velcro fleece surface 602, so that when the cloth strip 601 is bonded to one side of the Velcro hook surface 603, the exposed part of the screw 504 is covered, thereby minimizing the accumulation of excessive dust on the exposed part of the screw 504, which may cause the staff to be unable to normally adjust the position of the movable metal filter 502.

[0034] At the same time, the front and rear inner walls of the metal filter mesh 502 are respectively abutted against the adjacent sides of the filter layer 1 3 and the filter layer 2 4, so as to minimize the flow or drift of the subsequent filtered gas or liquid along the connection between the filter mechanism 5 and the filter layer 1 3 and the filter layer 2 4, thereby causing the filter mechanism 5 to be unable to adjust the filter aperture of the industrial filter cloth during use.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected.
