[0002] Nitrile rubber is a synthetic rubber with excellent oil resistance, wear resistance, aging resistance and chemical stability. It is synthesized by copolymerization of butadiene and acrylonitrile, hence the name nitrile rubber. Due to its special properties, nitrile rubber is widely used in various industrial fields, including automobiles, aerospace, petrochemicals, wires and cables, seals, etc.

[0003] The production of nitrile rubber adopts emulsion polymerization method. During the rubber post-processing process, it needs to be washed, which produces a large amount of rubber wastewater. Affected by the characteristics of nitrile rubber itself and the wastewater treatment process, the wastewater generated by the device carries a large number of rubber particles with a particle size of less than 6mm, so it is necessary to use a filtering device to filter the rubber particles in the wastewater. At present, most filtering equipment is fixed with multiple bolts during installation, so when the filter element needs to be cleaned, it takes a lot of time to remove the bolts, thereby reducing the cleaning efficiency. For this reason, a filtering device for nitrile rubber wastewater treatment is proposed. Utility Model Content

[0030] like Figures 1 to 5As shown, a filtering device for treating nitrile rubber wastewater comprises: a fixed barrel 1, which is open at one end, and an outlet pipe 101 and a sewage pipe 102 are respectively arranged on the outside of the fixed barrel 1, and the outlet pipe 101 and the sewage pipe 102 are both connected to the fixed barrel 1; a sealing cover 2, which is arranged on the outside of the fixed barrel 1 and is used to filter the sewage; a connecting component 3, which is arranged on the outside of the sealing cover 2 and is used to fix the sealing cover 2; a limiting component 4, which is arranged inside the connecting component 3 and is used to limit the connecting component 3. Specifically, when in use, the sewage is filtered by the cooperation of the sealing cover 2 and the fixed barrel 1. When the filter screen needs to be cleaned, the sealing cover 2 and the fixed barrel 1 are quickly installed and disassembled by the cooperation of the limiting component 4 and the connecting component 3, thereby shortening the cleaning time and improving the filtering efficiency of the sewage.

[0031] like Figures 1 to 5 As shown, a filter plate 103 is further provided inside the fixed barrel 1, and there are multiple filter plates 103. Specifically, filter materials are provided between the filter plates 103, so that the filtered sewage is filtered again through the filter materials, further ensuring the filtering effect of the sewage.

[0032] like Figures 1 to 5 As shown, the sealing cover 2 is arranged at the open end of the fixed barrel 1, and the outer side of the sealing cover 2 is respectively provided with an inlet pipe 201 and a filter element 202, and the water inlet pipe 201 is communicated with the filter element 202. Specifically, the filter element 202 is made of metal, and a plurality of drainage holes are opened on the outer side of the filter element 202. A plurality of filter materials are arranged inside the filter element 202, and the filter element 202 provides support for the plurality of filter materials to avoid displacement of the filter materials when filtering sewage, thereby ensuring stability during use. The filter element 202 and the sealing cover 2 can be connected by means of threads or snaps, so as to facilitate replacement and cleaning of the filter materials inside the filter element 202 during long-term use. When filtering sewage, the sewage is blocked by the cooperation of the sealing cover 2 and the fixed barrel 1, thereby avoiding overflow of sewage through the top of the fixed barrel 1 during use, thereby ensuring stability during use.

[0033] like Figures 1 to 5As shown, the connecting assembly 3 includes a first fixing ring 301 and a first fixing ring 301, the first fixing ring 301 and the second fixing ring 302 are respectively connected to the sealing cover 2 and the fixed barrel 1, the first fixing ring 301 is provided with an insert ring 303 on one side relative to the second fixing ring 302, the second fixing ring 302 is provided with a groove 306 on one side relative to the first fixing ring 301, the insert ring 303 is adapted to the groove 306, a cavity 304 is provided inside the first fixing ring 301, a sliding hole 305 is provided on the side wall of the cavity 304, and there are multiple sliding holes 305, and an annular groove 307 is provided on the side wall of the groove 306, specifically, the insert ring 303 cooperates with the groove 306 to guide the positions of the second fixing ring 302 and the first fixing ring 301, so as to avoid the first fixing ring 301 and the second fixing ring 302 being staggered when fixed, resulting in a gap between the sealing cover 2 and the fixed barrel 1, thereby causing sewage leakage.

[0034] like Figures 1 to 5 As shown, the limiting assembly 4 includes a wedge ring 401, which slides inside the cavity 304, and a threaded rod 402 is provided at one end of the wedge ring 401, and the threaded rod 402 is multiple, and one end of the threaded rod 402 passes through the first fixed ring 301, and a ball 404 is provided on the outside of the wedge ring 401, and the ball 404 is multiple, and the ball 404 corresponds to the sliding hole 305, and the ball 404 slides inside the sliding hole 305, and the ball 404 is adapted to the annular groove 307. Specifically, the threaded rod 402 is movably connected to the first fixed ring 301, and the diameter of the sliding hole 305 relative to the annular groove 307 is smaller than the diameter of the ball 404, so that the sliding hole 305 limits the ball 404 , to prevent the ball 404 from sliding out of the sliding hole 305, the contact surface between the wedge ring 401 and the ball 404 is an inclined surface, so that the position of the ball 404 can be controlled while the wedge ring 401 moves along the cavity 304. When the insert ring 303 is inserted into the groove 306, the wedge ring 401 is first driven to move by the threaded rod 402. When the wedge ring 401 moves, the ball 404 is squeezed to slide out of the sliding hole 305 along the sliding hole 305, so that the outer side of the ball 404 fits with the annular groove 307, thereby fixing the position of the second fixing ring 302 and the first fixing ring 301, and preventing the first fixing ring 301 from separating from the second fixing ring 302 during use, causing sewage leakage.

[0035] like Figures 1 to 5As shown, a rotating ring 403 is provided on the outer side of the threaded rod 402, and the rotating ring 403 is screwed to the threaded rod 402. Specifically, since the threaded rod 402 is connected to the wedge ring 401, the wedge ring 401 is moved while the threaded rod 402 is pulled to move. After the threaded rod 402 stops moving, the rotating ring 403 is rotated to abut against the first fixed ring 301, so that the positions of the threaded rod 402 and the wedge ring 401 are fixed through the cooperation of the threads, thereby preventing the wedge ring 401 and the threaded rod 402 from moving downward during the disassembly process.
