Therefore, these and other directional terms should not be construed as limiting terms.
Example 1:
referring to fig. 1-7, a light material mold filter plate comprises a filter plate 1 and a filter plate frame 2. The filter plate 1 is in a flat square structure, the filter plate frame 2 is in a square structure matched with the size of the filter plate 1, and the filter plate frame 2 is arranged on the edge of the filter plate 1. The filter plate frame 2 comprises an outer frame 21 and an inner frame 22, the outer frame 21 is arranged on the edge of the filter plate 1, the thickness of the outer frame 21 is larger than that of the filter plate 1, and the edge of the filter plate 1 is arranged in the middle of the outer frame 21, so that the cut surfaces of the filter plate 1 and the outer frame 21 are in a T shape. The inner frame 22 is arranged on the inner peripheral surface of the outer frame 21 and the surface of the filter plate 1, the thickness of the inner frame 22 is gradually reduced from outside to inside, and the cross section of the inner frame 22 is of a slope-shaped structure, so that the filter plate frame 2 is gradually transited from the surface of the outer frame 21 to the surface of the filter plate 1.
The material mould filter plate of this application need use with the water mould cooperation, and at the in-process of filter-pressing thick liquids, the water mould is to pressing to filter plate 1, thereby thick liquids are extruded moisture by water mould and filter plate 1 and are formed the filter cake sediment, consequently filter plate 1 is higher to structural strength's requirement. The filter plates of the stock mold are covered with filter cloth layers on both sides (refer to the applicant's prior patent application 2020105859958), the width of the outer frame 21 is larger than that of the filter plate 1, so that the filter cloth layers, the outer frame 21, the inner frame 22 and the filter plate 1 define a cavity for containing the slurry, and the outer frame 21 has high requirements on deformation resistance due to the sealing property because the filter cloth layers are clamped by the frames of the outer frame 21 and the water mold to prevent the slurry from escaping; in addition, the outer frame 21 is used as an edge frame structure of the material mold filter plate, and components for installation are required to be arranged to assemble the material mold filter plate on the filter press, and other functional components are required to be arranged based on other functional requirements, so that the requirement on structural strength is relatively high. The inner frame 22 has the structural characteristic that the cross section is in a slope shape, so that the acting force applied to the unit area in the filter pressing process is smaller than that applied to the filter plate 1, and the requirement on the structural strength is relatively low.
In order to reduce the overall weight of the material mold filter plate, the inner frame 22 is at least partially made of a synthetic resin-based casting body, and the remaining parts of the material mold filter plate are made of rigid metal bodies. More specifically, the synthetic resin-based casting is preferably an epoxy casting, and other casting such as a PP casting, a PVC casting, or the like may be used. The rigid metal body is preferably made of steel, and other materials such as cast iron and stainless steel can be selected. The synthetic resin casting body, especially the epoxy resin casting body has strong cohesive force and compact molecular structure, so that the synthetic resin casting body has strong mechanical property and strong pressure load bearing performance in the filter pressing process. In addition, since the synthetic resin curing system contains polar groups such as epoxy groups, hydroxyl groups, ether bonds, amine bonds, and ester bonds, which are extremely active, and the epoxy cured product is provided with excellent adhesion to polar substrates such as metals, ceramics, glass, concrete, and wood, the fastness of the synthetic resin molded body to the outer frame 21 and the filter plate 1 is extremely reliable.
The inner frame 22 includes four corner portions 221 located at corners of the filter plate 1, and four frame sides 222 connecting adjacent corner portions 221. The frame side portion 222 is a synthetic resin casting, and the corner portion 221 is a rigid metal body. First, since the volume of the frame side portion 222 is larger than that of the corner portion 221, the frame side portion 222 is more required to be provided as a synthetic resin cast body in view of maximally reducing the weight of the material membrane filter plate 1. Secondly, based on the pressure condition of the filter plate frame 2 during pressure filtration, the surface of the filter plate frame is not suitable to have edges, and the filter plate frame is easy to damage under high-strength extrusion, so that the surface of the frame edge 222 is a plane, the surface of the corner part 221 is a curved surface, the frame edge 222 is set into a synthetic resin casting body, the material mold filter plate can be cast by inclining the material mold filter plate, the corner parts 221 at the two ends of the frame edge 222 can also limit the casting range, the casting process does not need other tools, and the operation is simple; when the corner portion 221 is a synthetic resin casting, the casting process is troublesome because the surface is a curved surface.
At least one slurry channel 31 is arranged inside the inner frame 22, one end of the slurry channel 31 for feeding, namely a feeding end 311, penetrates through the outer frame 21 and forms a feeding hole 3-1 on the outer peripheral surface of the outer frame 21, the slurry channel 31 is connected with at least one discharging channel 32, and the discharging channel 32 is positioned inside the inner frame 22 and forms a discharging hole 3-2 on the surface of the inner frame 22. In general, the slurry passage 31 may be provided with a pipe for transporting slurry, which is externally connected to the feed port 3-1, and the feed port 3-1 is preferably provided at the lower portion of the outer frame 21 on the left or right side, for the convenience of installation of the pipe. The discharge passages 32 are usually provided in two, and discharge ports 3-2 are formed on the surfaces of the inner frame 22 on both sides of the die plate, and the discharge passages 32 are preferably provided in the inner frame 22 on the upper side in view of no backflow and rapid injection of the slurry.
In the present embodiment, the slurry passage 31 passes through the frame side portion 22, the corner portion 221, and a discharging portion 223 described below.
In the high-strength pressed state, the synthetic resin-based molded body is more likely to be deformed than the rigid metal body, and therefore, the portion of the slurry channel 31 located at the frame side portion 222 is likely to be pressed and narrowed, which affects the flow rate of the slurry and is likely to cause clogging. Therefore, the slurry pipe 3-a is inserted into the slurry passage 31 in the frame side portion 222, and the end of the slurry pipe 3-a extends to the slurry passage 31 of the corner portion 221. The slurry pipe 3-A is a seamless pipe, especially a carbon steel seamless pipe, which has better structural strength, can maintain the shape of the slurry channel 31 under high-strength extrusion, provides stable and reliable slurry conveying, and improves the sealing property when the end part of the slurry pipe 3-A extends to the corner part 221.
The provision of the slurry pipe 3-a also simplifies the pouring process by inserting the end portion of the slurry pipe 3-a into the slurry passage 31 of the corner portion 221 before pouring, and then pouring the synthetic resin into the frame side portion 222.
The feeding end 311 of the slurry channel 31 is positioned in the corner part 221, and the corner part 221 and the outer frame 21 are both rigid metal bodies, so that the connection between the feeding end 311 and the feeding port 3-1 is reliable, and the stable circulation and conveying of the slurry are ensured.
In addition, the inner frame 22 further comprises a discharging part 223 cutting and splicing the frame edge part 222, the discharging channel 32 is arranged in the discharging part 223, the discharging port 3-2 is formed on the surface of the discharging part 223, and the discharging part 223 is a rigid metal body, so that the discharging channel 32 is not deformed and narrowed under pressure, and the stability of discharging is ensured.
At least one drainage channel 41 is arranged inside the inner frame 22, one end of the drainage channel 41 for drainage, namely a water outlet end 411, penetrates through the outer frame 21 and forms a drainage port 4-1 on the outer periphery of the outer frame 21, a plurality of drainage through holes 42 are arranged on the frame edge 222, and two ends of the drainage through holes are respectively communicated with the surface of the frame edge 222 and the drainage channel 41. According to the above, the slurry passage 31 occupies two frame side portions 222, and thus the remaining two frame side portions 222 are each provided with one drain passage 41.
For the same purpose of providing the slurry pipe 3-a in the slurry passage 31, a water pipe 4-a is inserted into the water discharge passage 41 of the frame side portion 222, the end of the water pipe 4-a extends into the water discharge passage 41 of the corner portion 221, the water pipe 4-a is provided with a through hole to engage with the water discharge through hole 42, so that the two ends of the water discharge through hole 42 communicate with the surface of the frame side portion 222 and the water pipe 4-a, respectively, and the water pipe 4-a is also seamless pipe. Before casting, the end of the water pipe 4-a is inserted into the drainage channel 41 of the corner 221, the synthetic resin is cast into the frame edge 222, and then the drainage through hole 42 is drilled by using a drill.
Also, the water outlet end 411 of the drain passage 41 is located in the corner portion 221, thereby ensuring stable drainage.
The surface of the filter plate 1 is provided with a plurality of filter plate bosses 11, the filter plate bosses 11 are uniformly distributed on the front surface and the back surface of the filter plate 1, and structurally, the filter plate bosses 11 are formed along the front surface/the side surface of the filter plate 1 in a protruding mode, so that the effect of distributing stress load is achieved. In addition, the side surface of the filter plate boss 11 is sleeved with a wear-resistant sleeve 111 to reduce the friction damage between the filter plate boss and slurry.
Example 2:
referring to fig. 7 and 8, a lightweight material die-cast filter plate of the present embodiment differs from embodiment 1 in that a resin-based casting body is synthesized in all corner portions 221 and frame side portions 222 of an inner frame 22 except for a discharge portion 223. Further, since the corner portion 221 and the frame edge portion 222 are synthetic resin molded bodies, a continuous slurry pipe is inserted into the slurry passage, and a continuous drain pipe is inserted into the drain passage.
The overall weight of the material mold filter plate is lighter than in embodiment 1, but the casting process is relatively complicated.
The casting may be performed using tooling that includes a mold frame a1 adapted to fit within interior casing 22, a plurality of clevis a2, and a plurality of strip fasteners A3. The casting process is as follows:
injecting synthetic resin into the inner frame 22 (corner portion 221, frame portion 222); covering the mold frame A1 on the inner frame 22 and applying a certain acting force, specifically, after the material mold filter plate is flatly placed, pressing down the mold frame A1, and cleaning the overflowing synthetic resin; the U-shaped clamp A2 is used for buckling into the outer frame 21, and fasteners (such as screws) are used for fixing the die frame A1 so that the die frame A1 cannot fall off the material die filtering plate; fixing two ends of the strip fixing piece A3 on two opposite sides of the die frame A1 by using fasteners, wherein a plurality of strip fixing pieces A3 are arranged in a cross shape, and channel steel can be used as the strip fixing pieces A3; and (3) putting the material mold filter plate into a heating furnace, heating and curing the synthetic resin, taking out the synthetic resin, and removing the mold frame A1, the plurality of U-shaped clamps A2 and the strip fixing pieces A3.
Example 3:
