Description

Technical Field

[0001] The utility model relates to the technical field of filter presses, in particular to a combined stainless steel filter plate structure. Background Technique

[0002] Efficient, energy-saving and environment-friendly solid-liquid separation technology has become an indispensable important process in various industries. Solid-liquid separation technology is a process used to separate solids and liquids, and is widely applied in fields such as industry, environmental protection and food processing. Its main purpose is to improve the utilization rate of resources, reduce pollution and improve product quality. To meet the increasingly severe filtration tasks required by the market, it is necessary to continuously shorten the filtration time and improve the filtration effect.

[0003] The filter plates used in the existing solid-liquid separation have the following problems in the use process: the filter plate frames mostly adopt an integrated design, which has high processing difficulty and high subsequent replacement and maintenance costs. Secondly, for the filter screen structure used in the middle of the filter plate, when receiving a large amount of solid-liquid mixture for filtration, when the force is uneven, it is easy to be squeezed and damaged, and when encountering solids with different particles, it is extremely easy to cause the blockage of the filter screen, affecting the filtration efficiency;

[0022] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0023] Please refer to Figures 1-4A combined stainless steel filter plate structure includes a filter plate body; the filter plate body includes a filter plate frame and a filter mechanism, the filter plate frame is wrapped around the outside of the filter mechanism, and is used to firmly position the filter mechanism and maintain the overall strength and rigidity of the filter plate body. The filter mechanism is set to a polygonal structure, and the filter plate frame includes an angle insert 1 and an edge insert 2, which are staggered and wrapped around the filter mechanism to form a rectangular structure. The filter mechanism includes two layers of perforated mesh 8 embedded inside the rectangular structure formed by the angle insert 1 and the edge insert 2, and the perforated mesh 8 is used to filter the solid-liquid mixture to be filtered. Double filtration is carried out, a layer of woven mesh 9 is clamped in the middle of the two layers of perforated mesh 8, and a feed port is connected to the outside from the center of the perforated mesh 8 on one side. The solid-liquid mixture to be filtered is input along the feed port, and then diffused toward the surroundings with the feed port as the center, and first-level filtration is performed through the upper perforated mesh 8 in advance, and then transferred under the action of gravity, through the woven mesh 9, and finally through the lower perforated mesh 8 for secondary filtration before being discharged. The woven mesh 9 plays a supporting role inside the perforated mesh 8 to prevent the filter plate from being squeezed and damaged during operation, thereby increasing the service life of the filter plate. In addition, the setting of the woven mesh 9 can prevent the filter plate filter holes from being blocked, thereby improving the filtration and dehydration efficiency.

[0024] In the embodiment of the present invention, adjacent corner inserts 1 and side inserts 2 are connected by a snap-fit ​​connection, which facilitates installation and disassembly. When the filter mechanism is partially damaged, the corresponding corner insert 1 or side insert 2 can be removed to repair it. A through hole is opened on the corner insert 1, and the through hole is used to cooperate with the external fastening structure to fix the filter plate frame.

[0025] In one embodiment of the present invention, a group of feed port inserts Ⅱ7 with an annular structure are installed around the feed port, and a circle of feed port inserts Ⅰ6 are installed in a clamping manner between the feed port inserts Ⅱ7 and the surrounding perforated mesh 8 and woven mesh 9. The feed port inserts Ⅰ6 are used to stably connect the feed port with the surrounding perforated mesh 8 and woven mesh 9, and at the same time cooperate with the feed port inserts Ⅱ7 to reduce the direct impact of the solid-liquid mixture to be filtered on the filter plate, reduce the wear on the filter plate, and at the same time, the feed port inserts Ⅰ6 and the feed port inserts Ⅱ7 can improve the sealing of the connection, prevent material leakage, and increase the diversion function.

[0026] As a preferred embodiment of the present invention, a plurality of boss assemblies are evenly installed on the filter mechanism centered on the feed port, and the boss assemblies include detachably connected boss inserts Ⅰ4 and Ⅱ5, wherein the boss inserts Ⅰ4 and Ⅱ5 are longitudinally penetrated and installed on the punching nets 8 and woven nets 9 on both sides. The boss assemblies can improve the overall strength and rigidity of the filter plate to prevent deformation or rupture under working pressure, better fix the filter medium to ensure that it does not move during the filtration process, and improve the fluid distribution: the design of the boss assemblies helps to improve the flow distribution of the fluid on the filter plate, so that the fluid can pass through the filter medium evenly, thereby improving the filtration efficiency.

[0027] The above describes in detail the preferred embodiments of the present patent. However, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the scope of knowledge possessed by those of ordinary skill in the art.
