Fine slurry is subjected to high-intensity pressure in the filter press, so that the liquid is dialyzed out, and the solid is called filter cake. For example, in the prior art, the diaphragm filter press model XMY-800-ue will cover the outer end of the filter plate with a filter cloth before the filter plate is used, so as to facilitate the discharge of the filter cake after filtration, and at the same time, it can also facilitate the service life of the filter plate and facilitate the cleaning of the filter plate.

DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0020] like Figure 1-4As shown, the utility model provides a technical solution: an ultra-high pressure filter press for liquid-solid separation of fine slurry, comprising a filter press body 1, a plurality of filter plates 2 are installed on the inner side of the filter press body 1, a through opening 201 is opened on the side end of each filter plate 2, and a filter assembly is installed on the outer end of each filter plate 2. The solid-liquid separation operation of the fine slurry can be realized by setting the filter press body 1, the plurality of filter plates 2 and the filter assembly. The top and bottom ends of each filter plate 2 are provided with a plurality of limiting mechanisms for fixing the filter assembly, the limiting mechanisms include a mounting assembly and a plurality of rebound assemblies, and the plurality of rebound assemblies are all located inside the mounting assembly. During implementation, through the setting of the limiting mechanism, not only the fixing effect of the filter assembly is improved, but also the filter assembly can be conveniently disassembled later, so that the filter assembly is not easy to loosen during the movement and use of the filter plate 2, thereby avoiding affecting the use effect of the filter press.
[0021] As an implementation method in this embodiment, Figure 2 and Figure 4 As shown, the filter assembly includes filter cloth 1 4, the side end of which is fixedly connected with connecting cloth 401, which is compatible with the through opening 201, and the side end of connecting cloth 401 is fixedly connected with filter cloth 2 402, and the top and bottom ends of filter cloth 1 4 are both provided with a plurality of sleeves 403, and the top and bottom ends of filter cloth 2 402 are both provided with a plurality of sleeves 403. In practice, by rolling filter cloth 2 402 together and passing it through the through opening 201, at this time, pulling filter cloth 2 402 so that connecting cloth 401 is located in the through opening 201, the preliminary installation of filter cloth 1 4 and filter cloth 2 402 on the filter plate 2 is completed.
[0022] As an implementation method in this embodiment, Figure 3As shown, the mounting assembly includes a fixing rod 3, the fixing rod 3 is fixedly connected to the top of the filter press body 1, the top of the fixing rod 3 is fixedly connected to a fixing box 301, the middle of the fixing box 301 is fixedly connected to a vertical plate 302, a plurality of rebound assemblies are respectively located at the left and right side ends of the vertical plate 302, the rebound assembly includes a round rod 303, the round rod 303 is fixedly connected between the inner wall of the fixing box 301 and the side end of the vertical plate 302, the outer end of the round rod 303 is sleeved with a spring 304, and the round rod 30 The outer end of the filter cloth 301 is sleeved with a sleeve plate 305, and the side end of the sleeve plate 305 is fixedly connected with a connecting plate 306, which penetrates the outer side end of the fixed box 301, and the side end of the connecting plate 306 is fixedly connected with a pressing plate 307. Since the pressing plate 307 is arranged in an arc shape, it is convenient to pass through the sleeve opening 403. In implementation, the sleeve opening 403 at the top of the filter cloth 4 is aligned with the position of the pressing plate 307. At this time, by pinching the pressing plates 307 at both ends, the pressing plates 307 drive the connecting plate 30 6 and the sleeve plate 305 move along the outer end of the round rod 303, at this time, the sleeve plate 305 can press the spring 304 to shrink, at this time, when the straight-line distance between the pressing plates 307 at both ends is less than the diameter of the sleeve 403, the sleeve 403 can be downwardly sleeved on the outer end of the fixed rod 3, at this time, after the pressing plate 307 is released, the spring 304 rebounds against the sleeve plate 305, driving the connecting plate 306 and the pressing plate 307 to expand outward, at this time, the straight-line distance between the two sets of pressing plates 307 is greater than the straight-line distance between the sleeve 403 diameter, so the sleeves 403 at the top and bottom ends of the filter cloth 1 4 can be respectively put on the outer ends of each fixed rod 3 to complete the installation of the filter cloth 1 4, and then the filter cloth 2 402 can be put on the outer ends of each fixed rod 3 in the same way as above to complete the installation of the filter cloth 2 402. At this time, the filter cloth 1 4 and the filter cloth 2 402 can be fixed on the outer ends of the filter plate 2, so that the filter cloth 1 4 and the filter cloth 2 402 are difficult to separate from the fixed rod 3 without pressing the two sets of pressing plates 307.
[0023] Working principle: by rolling the filter cloth 2 402 together and passing it through the through-port 201, the filter cloth 2 402 is pulled at this time so that the connecting cloth 401 is located in the through-port 201. After the filter cloth 2 402 is spread out at this time, the sleeve 403 at the top of the filter cloth 1 4 is aligned with the position of the pressing plate 307. At this time, by pinching the pressing plates 307 at both ends, the pressing plates 307 drive the connecting plate 306 and the sleeve plate 305 to move along the outer end of the round rod 303. At this time, the sleeve plate 305 can press the spring 304 to shrink. At this time, when the straight-line distance between the pressing plates 307 at both ends is less than the diameter of the sleeve 403, the sleeve 403 can be downwardly sleeved on the outer end of the fixed rod 3. At this time, after the pressing plate 307 is released, the spring 304 rebounds against the sleeve plate 305, driving the connecting plate 306 and the pressing plate 307 to expand outward. At this time, the straight-line distance between the two sets of pressing plates 307 is greater than the sleeve 4 03 in diameter, so the sleeves 403 at the top and bottom ends of the filter cloth 1 4 can be respectively sleeved on the outer ends of each fixing rod 3, thereby completing the installation of the filter cloth 1 4, and then the filter cloth 2 402 can be sleeved on the outer ends of each fixing rod 3 in the same manner as described above, thereby completing the installation of the filter cloth 2 402. At this time, the filter cloth 1 4 and the filter cloth 2 402 can be fixed to the outer ends of the filter plate 2, so that the filter cloth 1 4 and the filter cloth 2 402 are difficult to separate from the fixing rod 3 without pressing the two sets of pressing plates 307, which not only improves the fixing effect of the filter cloth 1 4 and the filter cloth 2 402, but also facilitates the subsequent disassembly of the filter cloth 1 4 and the filter cloth 2 402. Due to the limitation of the sleeves 403 by the pressing plates 307, the filter cloth 1 4 and the filter cloth 2 402 are not easy to loosen during the movement and use of the filter plate 2, thereby avoiding affecting the use effect of the filter press.
[0024] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
