Description

Technical Field

[0001] This utility model belongs to the technical field of filter press equipment, specifically relating to a filter press for high-efficiency purification of MBT. Background Technology

[0002] A filter press is a mechanical device that uses a special filter medium to apply pressure to a material, causing the liquid to seep out. It is a commonly used solid-liquid separation device. MBT purification requires a filter press. Currently, most filter presses used for MBT purification can only filter the slurry, resulting in low filtration efficiency and difficulty in cleaning the filter residue. Therefore, a high-efficiency filter press for MBT purification is needed to solve these technical problems. Utility Model Content

[0003] To address the aforementioned deficiencies in existing technologies, this utility model provides a high-efficiency MBT purification filter press, comprising an upper chamber and a lower chamber. The upper chamber is fixed to the lower chamber and communicates vertically with it. A drain pipe is located at the bottom of the upper chamber, and a slag discharge pipe is located at the bottom of the lower chamber. Both the drain pipe and the slag discharge pipe are equipped with on / off valves. A filter cartridge with openings at the top and bottom is located inside the upper chamber, with its bottom connected to the lower chamber. A pressure plate is located on the upper chamber, and a vertical telescopic rod is connected to the top of the pressure plate. A feed pipe that mates with the filter cartridge is located on the upper chamber. A filter plate that matches the filter cartridge is located inside the lower chamber, and a second vertical telescopic rod is connected to the bottom of the filter plate.

[0004] Preferably, the bottom of the filter cartridge is rotatably connected to the lower housing via a bearing. A limiting block is provided along the edge of the filter plate, and a matching groove is provided on the inner wall of the filter cartridge corresponding to the limiting block. The fixed end of the second vertical telescopic rod is rotatably connected to the lower housing via a bearing, and the telescopic end of the second vertical telescopic rod extends into the lower housing and is fixedly connected to the center of the filter plate. A bevel gear is fixed to the fixed end of the second vertical telescopic rod outside the lower housing, and the bevel gear meshes with a second bevel gear. The second bevel gear is connected to a stepper motor. The second vertical telescopic rod is an electric push rod and can be connected to a power source via a conductive slip ring. During filtration, the filter plate moves upward to seal the lower end of the filter cartridge. At this time, the limiting block is located in the groove, and the stepper motor drives the filter plate to rotate. Under the limiting action of the limiting block and the groove, the filter cartridge rotates synchronously with the filter plate. Under the action of centrifugal force, and simultaneously with the downward pressure of the pressure plate, the separation efficiency of the filtrate and filter residue is improved.

[0005] Preferably, the edge and bottom of the pressure plate are provided with bristles. The rotation of the filter plate helps to clean the filter residue on the inner wall of the filter cylinder and the filter plate, causing it to fall into the lower chamber and be discharged through the residue outlet pipe.

[0006] Preferably, the vertical telescopic rod is an electric push rod or a hydraulic cylinder.

[0007] Preferably, one end of the feed pipe extends into the upper housing and is located above the filter cartridge, while the other end of the feed pipe is connected to a guide hose. The feed pipe is also connected to a horizontal telescopic rod, which is fixedly connected to the outer wall of the upper housing. The position of the feed pipe within the upper housing is adjusted by extending and retracting the horizontal telescopic rod. During feeding, the feed pipe is located above the filter cartridge; after feeding, the feed pipe moves away from the filter cartridge to prevent it from obstructing the downward pressure of the pressure plate.

[0008] This invention also includes other components that enable the normal operation of a filter press for high-efficiency MBT purification, such as control components for stepper motors, electric actuators, hydraulic cylinders, and control components for controlling the feeding of the feed hose (e.g., a feed pump), all of which are conventional technologies in the field. Furthermore, devices or components not limited in this invention, such as stepper motors, electric actuators, hydraulic cylinders, and switching valves, all employ conventional technologies and equipment in the field.

[0009] Working principle: During operation, the material to be filtered enters the filter cylinder through the feed pipe. The stepper motor drives the inner filter cylinder to rotate, the pressure plate presses down, the filtrate enters the upper chamber and is discharged through the drain pipe, and most of the filter residue remains on the filter plate. The vertical telescopic rod retracts, the filter plate separates from the filter cylinder, and the bristles on the pressure plate clean the filter residue on the inner wall of the filter cylinder and the filter residue on the filter plate into the lower chamber and are discharged by the slag discharge pipe.

[0010] The beneficial effects of this utility model are: reasonable structure, simple to use, improved filter pressing effect and efficiency, easy to clean filter cake, and reduced filter cake residue on filter cylinder and filter plate. Attached Figure Description

The inner wall of the filter cartridge 2 corresponding to the limiting block 16 is provided with a matching groove 17. The fixed end of the vertical telescopic rod 2 is rotatably connected to the lower housing 4 via a bearing. The telescopic end of the vertical telescopic rod 2 extends into the lower housing 4 and is fixedly connected to the center of the filter plate 3. A bevel gear 1 7 is fixed on the fixed end of the vertical telescopic rod 2 6 located outside the lower housing 4. The bevel gear 1 7 meshes with a bevel gear 2 8. The bevel gear 2 8 is connected to a stepper motor 9. The vertical telescopic rod 2 6 is an electric push rod. The vertical telescopic rod 2 6 can be connected to a power source through a conductive slip ring. During filtration, the filter plate 3 moves upward to block the lower end of the filter cylinder 2. At this time, the limiting block 16 is located in the groove 17. The stepper motor 9 drives the filter plate 3 to rotate. Under the limiting action of the limiting block 16 and the groove 17, the filter cylinder 2 rotates synchronously with the filter plate 3. Under the action of centrifugal force, the pressure plate 10 presses down to improve the separation efficiency of filtrate and filter residue.

[0019] The pressure plate 10 is provided with brush bristles 12 along its edges and bottom. The brush bristles 12, when used in conjunction with the rotation of the filter plate 3, can clean the filter residue on the inner wall of the filter cylinder and the filter plate 3, causing it to fall into the lower box 4 and be discharged from the residue outlet pipe.

[0020] The vertical telescopic rod 15 is an electric push rod or a hydraulic cylinder.

[0021] One end of the feed pipe 13 extends into the upper housing 1 and is located above the filter cartridge 2. The other end of the feed pipe 13 is connected to a guide hose. The feed pipe 13 is connected to a horizontal telescopic rod 14, which is fixedly connected to the outer wall of the upper housing 1.

During feeding, the feed pipe 13 is located above the filter cartridge 2. After feeding, the feed pipe 13 moves away from the filter cartridge 2 to avoid obstructing the downward pressure of the pressure plate 10.

[0022] During operation, the material to be filtered enters the filter cylinder through the feed pipe. The stepper motor drives the inner filter cylinder to rotate, the pressure plate presses down, the filtrate enters the upper chamber and is discharged through the drain pipe, while most of the filter residue remains on the filter plate. The vertical telescopic rod retracts, the filter plate separates from the filter cylinder, and the brush on the pressure plate cleans the filter residue on the inner wall of the filter cylinder and the filter residue on the filter plate into the lower chamber and is discharged through the slag discharge pipe.
