Description

Technical Field

[0001] This invention relates to the field of solid-liquid separation equipment technology, and in particular to a multifunctional chamber filter press. Background Technology

[0002] A chamber filter press can extract solids from a liquid mixture, achieving solid-liquid separation. It is used in industries such as pharmaceuticals, chemicals, standard parts, pharmaceutical manufacturing, metallurgy, non-standard screws, dyes, food, brewing, ceramics, oil refining, and wastewater treatment. A chamber filter press includes a frame, multiple movable filter mechanisms mounted on the frame, a clamping device to press the filter mechanisms together, a drive device to open the filter mechanisms one by one, and a drainage device mounted on the frame and connected to the filter mechanisms.

[0003] In existing chamber filter presses, the drive unit pulls open the filter mechanisms one by one, allowing the filter cake between the two filter mechanisms to fall and be cleaned. However, this method of cleaning the filter cake is slow and affects the solid-liquid separation efficiency of the filter press. Summary of the Invention

[0004] The purpose of this invention is to provide a multifunctional chamber filter press that can simultaneously open multiple filtration mechanisms to improve the efficiency of cleaning filter residue.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a multi-functional chamber filter press, comprising a frame, multiple filtration mechanisms movably mounted on the frame, a pressing device for pressing the multiple filtration mechanisms, a driving device for pulling the filtration mechanisms apart one by one, and a draining device mounted on the frame and communicating with the multiple filtration mechanisms. The filter plates of each filtration mechanism are provided with driving blocks on both sides for clamping by the driving device. The driving device includes a movable seat movably mounted on the frame, a power mechanism disposed between the side of the frame and the movable seat and driving the movable seat, multiple adjusting blocks movably mounted on the movable seat, an adjusting mechanism disposed between the multiple adjusting blocks and the movable seat and maintaining the same distance between the multiple adjusting blocks, a locking seat rotatably mounted on the adjusting block, and a driving mechanism disposed between the adjusting mechanism and the locking seat and locking the multiple locking seats after rotation and locking them onto the driving blocks. The operation steps of the drive device are as follows: (S1) The power mechanism causes the moving seat to move to the drive block of the corresponding multiple filter mechanisms; (S2) The drive mechanism drives the fastening seat to rotate, so that the fastening seat fastens onto the drive block of the filter plate of the filter mechanism; (S3) The power mechanism drives the moving seat to move towards the pressing device, and during the movement, the adjustment mechanism drives the multiple adjustment blocks to move away from each other and maintain the same distance, so that the filter plates of the multiple filter mechanisms open at the same distance, so that the filter residue falls off; (S4) The power mechanism drives the moving seat to move towards the pressing device to the limit position, and the adjustment mechanism adjusts the distance between the multiple adjustment blocks to the minimum position, so that the corresponding multiple filter mechanisms overlap; (S5) The drive mechanism drives the fastening seat to disengage from the drive block of the filter plate of the filter mechanism; (S6) Repeat steps S1 to S5, so that the filter residue in all filter mechanisms falls off.

[0006] A further feature of the present invention is that, in step (S3), the spacing between multiple adjusting blocks is repeatedly reduced and increased by the adjusting mechanism, thereby accelerating the falling of filter residue between the two filtering mechanisms.

[0007] A further embodiment of the present invention is that the power mechanism includes a rack disposed on the side of the frame, a first motor disposed on the movable seat, and a gear disposed on the output shaft of the first motor and meshing with the rack.

[0008] A further configuration of the present invention is as follows: the adjusting mechanism includes an adjusting screw rotatably connected at both ends to a movable seat and passing through the lower ends of multiple adjusting blocks; a screw nut disposed on an adjusting block near one end of the pressing device and mating with the adjusting screw; multiple first connecting rods hinged in the middle to the sides of multiple adjusting blocks without screws; a second connecting rod hinged at one end to an adjusting block with a screw nut; a third connecting rod hinged at one end to the movable seat away from the pressing device; a second motor disposed on the movable seat and linked to one end of the adjusting screw; the end plates of the multiple first connecting rods that are close to each other are hinged together and form a zigzag shape; the other end of the second connecting rod is hinged to the end of the first connecting rod that is close to it; and the other end of the third connecting rod is hinged to the end of the first connecting rod that is close to it.

[0009] A further configuration of the present invention is as follows: the driving mechanism includes a support plate disposed on the side of the movable seat away from the filter mechanism and extending along the length direction of the movable seat; a plurality of driving cylinders laterally disposed on the support plate; and a wedge-shaped driving plate disposed on the cylinder rods of the plurality of driving cylinders. The fastening seat is provided with a wedge-shaped portion that matches the wedge-shaped driving plate. When the wedge-shaped driving plate abuts against the wedge-shaped portion of the fastening seat, the fastening seat fastens onto the driving block. The center of gravity of the fastening seat is located on the side of the fastening seat away from the filter mechanism from the hinge axis. When the wedge-shaped driving plate and the wedge-shaped portion of the fastening seat separate, the fastening seat rotates outward under the action of gravity to separate from the driving block.

[0010] A further provision of the present invention is that: the side of the fastening seat is provided with an arc-shaped sleeve having an arc-shaped hole centered on the hinge axis of the fastening seat; the adjusting block is provided with an arc-shaped rod passing through the arc-shaped sleeve; a first compression spring is provided at one end of the arc-shaped rod passing through the arc-shaped sleeve; and an anti-detachment end cap is provided at the end of the arc-shaped rod to prevent the compression spring from falling off.

[0011] A further feature of the present invention is that: the fastening seat is provided with a fastening groove, and the fastening groove has opening slots on both sides. An elastic pad assembly is provided in the opening slot. During the process of the fastening seat fastening the driving block, the driving block first contacts only the two elastic pad assemblies, and then contacts the inner walls on both sides of the fastening groove. In step (S3), the spacing between multiple adjusting blocks is repeatedly reduced and increased by the adjusting mechanism, and the driving block contacts only the two elastic pad assemblies, thereby accelerating the fall of filter residue between the two filtering mechanisms by forming vibration.

[0012] A further embodiment of the present invention is that the elastic pad assembly includes a buffer plate disposed in the opening groove, a guide shaft disposed on the buffer plate and extending through the fastening seat, a limiting nut disposed at one end of the guide shaft extending through the fastening seat, and a second compression spring sleeved on the guide shaft and with both ends pressed against the buffer plate and the opening groove.

[0013] In summary, the beneficial effects of this invention are:

[0014] 1. The operation steps of the drive device are as follows: (S1) The power mechanism causes the moving seat to move to the drive block of the corresponding multiple filter mechanisms; (S2) The drive mechanism drives the fastening seat to rotate, so that the fastening seat fastens onto the drive block of the filter plate of the filter mechanism; (S3) The power mechanism drives the moving seat to move towards the pressing device, and during the movement, the adjustment mechanism drives the multiple adjustment blocks to move away from each other and maintain the same distance, so that the filter plates of the multiple filter mechanisms open at the same distance, allowing the filter cake to fall off; (S4) The power mechanism drives the moving seat to move towards the pressing device to the limit position, and the adjustment mechanism adjusts the distance between the multiple adjustment blocks to the minimum position, so that the corresponding multiple filter mechanisms overlap; (S5) The drive mechanism drives the fastening seat to disengage from the drive block of the filter plate of the filter mechanism; (S6) Repeat steps S1 to S5, so that the filter cake in all filter mechanisms falls off; finally, multiple filter mechanisms can be opened at the same time to improve the efficiency of cleaning the filter cake.

[0015] 2. During the operation of the adjustment mechanism, the second motor drives the adjustment screw to move, and the adjustment block with the screw nut moves along the adjustment screw as it rotates. Through the linkage of multiple first links, second links and third links, the multiple moving blocks can be expanded or retracted while maintaining the same distance between them.

[0016] 3. The drive mechanism includes a support plate, a drive cylinder, and a wedge-shaped drive plate. When the drive cylinder moves the wedge-shaped drive plate towards the fastening seat, the fastening seat can be fastened onto the drive block of the filter plate of the filter mechanism. As the fastening seat moves with the adjusting block, the drive mechanism can maintain its driving state. At the same time, after the wedge-shaped drive plate and the fastening seat separate, the fastening seat can automatically reset due to the setting of the center of gravity of the fastening seat, the arc sleeve, the arc rod, the first compression spring, and the anti-detachment end cap.

[0017] 4. A fastening groove is provided on the fastening seat, and an opening groove is provided on both sides of the fastening groove. An elastic pad assembly is provided in the opening groove. During the process of the fastening seat fastening the driving block, the driving block first contacts only the two elastic pad assemblies, and then contacts the inner walls of both sides of the fastening groove. In step (S3), the distance between multiple adjusting blocks is repeatedly reduced and increased by the adjusting mechanism, and the driving block contacts only the two elastic pad assemblies, forming a vibration to accelerate the falling of filter residue between the two filtering mechanisms.
