Description

Technical Field

[0001] The utility model relates to the technical field of filter press equipment, in particular to a novel high-pressure filter plate system. Background Art

[0002] As a key component of filter press equipment, the filter press plate determines the efficiency and effectiveness of solid-liquid separation. Traditional filter press plates create a high-pressure medium chamber and a slurry chamber within the plate frame. The two chambers are separated by a diaphragm. The high-pressure medium squeezes the diaphragm and then the filter chamber to separate the solid and liquid in the slurry.

[0003] However, affected by the diaphragm strength and the pressure supply system, the high-pressure medium cavity can only provide a pressure of about 1.6 MPa to extrude the slurry, resulting in a low degree of solid-liquid separation and a high moisture content in the filter cake after solid-liquid separation. Utility Model Content

[0004] In view of this, the utility model provides a new type of high-pressure filter plate system, which can improve the drainage capacity, and the pressure of the telescopic mechanism during the filtration process can directly act on the pressed slurry. The pressure is increased during the slurry extrusion process, and the moisture content of the filter plate after filtration can be greatly reduced.

[0005] In order to achieve the above technical effects, the utility model provides a new high-pressure filter plate system, including:

[0006] A filter press plate, wherein the upper surface of the filter press plate is provided with a groove for accommodating filter press slurry;

[0007] A longitudinal hole is formed on the bottom surface of the groove and extends toward the interior of the filter press plate;

[0008] A water guide groove is provided on the bottom surface of the groove and is used to connect the multiple longitudinal holes, and the water guide groove passes through the filter press plate;

[0009] The top plate is movably installed just above the filter press plate through a telescopic mechanism, and a first protrusion that fits with the groove is provided at the bottom of the top plate.

[0010] Furthermore, a filter cloth is laid in the groove, and the edge of the filter cloth extends outside the edge of the groove.

[0011] Furthermore, there are multiple filter press plates, which are overlapped in the vertical direction, and a second protrusion that fits into a groove of the next filter press plate is provided at the bottom of each filter press plate.

[0012] Furthermore, sealing strips are provided at the contact points between the top plate and the edge of the groove of the filter press layer plate, and at the contact points between the bottom surface of the upper filter press layer plate and the edge of the groove of the next adjacent filter press layer plate.

[0013] Furthermore, the sidewall of the groove is provided with a plurality of step-shaped bosses.

[0014] Furthermore, a water outlet hole is provided on the side surface of the boss close to the groove and passes through the corresponding side surface position.

[0015] Furthermore, it also includes a transverse hole, which passes through one side wall of the filter press plate to the other side wall of the filter press plate. The transverse hole is used to connect multiple longitudinal holes, and the transverse hole is arranged crosswise with the water guide groove.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. When the top plate of the utility model moves downward, the spacing between the filter press plates decreases, thereby squeezing the material for filter pressing. The bottom surface of the filter press plate groove is distributed with evenly spaced longitudinal holes, which are connected by V-shaped water guide grooves to improve drainage capacity.

[0018] 2. During the filtration process, the pressure of the telescopic mechanism can directly act on the slurry being pressed. The pressure increases during the slurry extrusion process, and the moisture content of the filter plate after filtration can be greatly reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Example

[0030] See also Figures 1-6 , a new type of high-pressure filter plate system, including:

[0031] The filter press plate 1 has an upper surface provided with a groove 101 for accommodating the filter press slurry 5;

[0032] A longitudinal hole 102 is formed on the bottom surface of the groove 101 and extends toward the interior of the filter press plate 1;

[0033] A water guide groove 103 is provided on the bottom surface of the groove 101 and is used to connect the plurality of longitudinal holes 102 . The water guide groove 103 passes through the filter press plate 1 .

[0034] The top plate 2 is movably installed just above the filter press plate 1 through a telescopic mechanism. The bottom of the top plate 2 is provided with a first protrusion 201 that fits with the groove 101.

[0035] In this embodiment, the novel high-pressure filter plate system is primarily used in vertical filter press equipment. The top plate 2 can move up and down with a telescopic mechanism, and the filter press plates 1 follow the top plate 2. As the top plate 2 moves downward, the spacing between the filter press plates 1 decreases, squeezing the material for filtration. The bottom surface of the grooves 101 of the filter press plates 1 is distributed with evenly spaced longitudinal holes 102, which are connected by V-shaped water guides 103 to enhance drainage capacity. During the filtration process, the pressure of the telescopic mechanism (e.g., a hydraulic cylinder) directly acts on the slurry 5 being squeezed. This increases the pressure during the slurry 5 extrusion process, significantly reducing the moisture content of the filter plates after filtration.

[0036] According to tests, when the new high-pressure filter plate system in this embodiment is used for filtration, the pressure during the extrusion of the slurry 5 can reach 5 MPa, and the moisture content of the filter plate after filtration can be reduced to about 40%.

[0037] In this embodiment, a filter cloth 3 is also laid in the groove 101, and the edge of the filter cloth 3 extends outside the edge of the groove 101. The setting of the filter cloth 3 can prevent a large amount of solid material in the slurry 5 from entering the longitudinal hole 102 or the water guide groove 103, avoiding the problem of easy blockage.

[0038] In this embodiment, the filter press plates 1 are multiple in number, and the multiple filter press plates 1 are vertically overlapped. The bottom of each filter press plate 1 is provided with a second protrusion 104 that fits into the groove 101 of the next filter press plate 1. The number of filter press plates 1 can be increased or decreased according to the product.

[0039] In this embodiment, a sealing strip 4 is provided at the contact point between the top plate 2 and the edge of the groove 101 of the filter press layer plate 1, and at the contact point between the bottom surface of the upper filter press layer plate 1 and the edge of the groove 101 of the adjacent lower filter press layer plate 1. During the filtration process, the upper and lower surfaces are in contact with the sealing strip 4 and squeezed against each other to achieve a seal during the filtration process.

[0040] The sidewalls of the groove 101 are provided with a plurality of stepped bosses 105. As in the present embodiment, the arrangement of the plurality of bosses 105 enables the filter press plate 1 to include a plurality of active surfaces, namely a, b1, c1, d1, and e1. The bottom surface of the upper filter press plate 1 also includes a plurality of active surfaces, namely f, b2, c2, d2, and e2, that mate with the bosses 105. During filtration, the a, b1, and f surfaces of each adjacent filter press plate 1 wrap around the filter cloth 3 to form a closed space. The slurry 5 is dehydrated by filtration in the closed space formed by the a, b1, and f surfaces. At the same time, the edge of the filter cloth 3 is compressed between the continuous surfaces of c1, d1, and e1 and the continuous surfaces of c2, d2, and e2 of the upper filter press plate 1, further enhancing the leak-proofing effect.

[0041] The side of the boss 105 near the groove 101 is provided with a water outlet hole 106 extending through the corresponding side position. Furthermore, it includes a transverse hole 107, which extends from one side wall of the filter press plate 1 to the other side wall of the filter press plate 1. The transverse hole 107 is used to connect the multiple longitudinal holes 102 and is arranged crosswise with the water guide groove 103. In this embodiment, the b1 surface and the g surface are connected by the water outlet hole 106, and the water outlet holes 106 are evenly spaced. At the same time, the longitudinal holes 102 on the a surface are connected by the transverse hole 107 passing through the g surface, further improving the drainage capacity of the side of the filter press plate 1 and the bottom of the groove 101.

[0042] It should be noted that the transverse hole 107 and the water guide groove 103 may be connected or not connected.

[0043] The above are only specific embodiments of the present application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
