Description

Technical Field

[0001] This utility model relates to the technical field of filter presses, and in particular to a filter pressing mechanism for a plate and frame filter press. Background Technology

[0002] A plate and frame filter press is a common solid-liquid separation device. It consists of a fixed plate, filter frames, filter plates, a pressing plate, and a pressing device. The filter plates and frames are arranged alternately, with filter cloth covering them to form the filter medium. The filter frames are hollow, and the filter plates and frames are supported by lugs on two horizontal parallel beams. One end is the fixed plate, and the pressing plate at the other end is tightened or loosened during operation by the pressing device. The working principle of the plate and frame filter press is to use the pressure difference between the plates and frames to separate solid particles from the suspension. Specifically, during operation, the suspension enters the filter chamber through the inlet. Under the action of the pressing device, the plates and frames are pressed tightly together, causing the liquid in the suspension to pass through the filter cloth and exit the filter chamber, while the solid particles remain inside. Typically, older plate and frame filter presses require manual separation of the plates after each operation to remove the solid particles.

[0003] The prior art Chinese utility model patent with application number CN202321245733.2 relates to a plate and frame filter press, including a base plate, a plate and frame filter press body, a filtration mechanism, a barrel, a motor, a rotating rod, filter plates, scrapers, guide pipes, valves, and a sliding plate, etc., which can push the solid particles intercepted on the filter plates into the filter frame for storage, thereby avoiding the clogging of the filter plates and ensuring the normal operation of secondary liquid filtration.

[0004] However, in actual use, the above-mentioned device requires manual separation of the plates and peeling off of the mud plates, which increases the labor intensity of the operators. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a filter press mechanism for a plate and frame filter press. The mechanism uses a horizontal moving device to move the equipment, a separating device to separate the plates sequentially, and a sludge scraping device to separate the mud pieces from the plates, allowing the mud pieces to fall off normally. This reduces the labor intensity of the operators and improves the practicality of the device.

[0006] This utility model discloses a plate and frame filter press mechanism, including a frame, support rods, and plates. Multiple sets of support rods are horizontally mounted on the frame, and multiple sets of plates are installed inside the frame, with each set of plates being limited by the support rods. The mechanism includes a transverse movement device, a separation device, and a sludge scraping device. The separation device and the sludge scraping device are mounted on the transverse movement device. The transverse movement device moves the equipment, cooperating with the separation device to sequentially separate the plates. The sludge scraping device separates the sludge from the plates, allowing the sludge to fall off normally, reducing the labor intensity of operators and improving the practicality of the device.

[0007] Preferably, the transverse movement device includes lead screws, a dual-output reducer, a motor, a transverse movement platform, and nuts. A set of lead screws is mounted on each of the left and right sides of the upper end face of the frame via brackets. A dual-output reducer is mounted on the front bracket, with its two output ends connected to the two sets of lead screws respectively. A motor is mounted on the dual-output reducer. The left and right sides of the transverse movement platform are each connected to the lead screw on their respective side via a set of nuts. Turning on the motor transmits power to the two sets of lead screws through the dual-output reducer, causing them to rotate. The rotating lead screws, in conjunction with the nuts, move the transverse movement platform back and forth between the plates, working with the separation device to separate adjacent plates. This reduces the labor intensity of operators during plate separation and can be installed on most older plate and frame filter presses, improving the device's practicality.

[0008] Preferably, the separation device includes an electric cylinder, a conical plate, and a chamfer. The electric cylinder is installed on the upper end face of the transverse platform, and a rectangular groove is provided on the lower end face of the transverse platform. The moving end of the electric cylinder extends through the upper end face of the transverse platform into the rectangular groove of the transverse platform and connects with the conical plate. The lower part of the conical plate is pointed, and the front and rear edges of the upper end face of the plate are chamfered. The transverse device moves the conical plate between two adjacent sets of plates. Then, the electric cylinder is controlled to extend so that the lower part of the conical plate is inserted between the two adjacent sets of plates through the chamfer, separating the connected plates. This facilitates the subsequent removal of the mud plates between the plates, reduces the labor intensity of the operators during the plate separation process, and improves the practicality of the device.

[0009] Preferably, it also includes a vibration motor. A rectangular hole is provided in the middle of the conical plate, and a vibration motor is installed on the upper surface of the rectangular hole of the conical plate. After the separation device presses the conical plate against the plate, the vibration motor is turned on to transmit power through the conical plate to the plate, causing the plate to vibrate. The adjacent plates loosen, reducing the pressure required to separate the plates, thereby reducing the pressure on the lead screw, and speeding up the separation process of the plates, thus improving the practicality of the device.

[0010] Preferably, it also includes limiting light rods. A set of limiting light rods is provided on the left and right sides of the upper end face of the conical plate. Both sets of limiting light rods extend through the transverse platform to the upper side of the transverse platform. The lifting and lowering process of the conical plate is limited by the two sets of limiting light rods, which reduces the vibration amplitude of the conical plate itself during the lifting and lowering process and improves the stability and practicality of the device.

[0011] Preferably, the sludge scraping device includes a rotating shaft, a separating shovel, and a drive rod. A set of grooves is provided on the left and right sides of the front and rear sides of the conical plate. Four sets of separating shovels are respectively installed in the four sets of grooves of the conical plate via the rotating shaft. A drive rod is provided on the upper part of the separating shovel. The drive rod extends upwards and outwards from the conical plate, and the angle between the drive rod and the horizontal plane is smaller than the angle between the front and rear end faces of the conical plate and the horizontal plane. After the conical plate is inserted between the two sets of plates, as the conical plate continues to move downwards, the plates contact the drive rod, pushing the drive rod to rotate, which in turn drives the separating shovels to rotate, causing the separating shovels to separate from the grooves on the conical plate. Then, the separating shovels rotate until they contact the plates, separating the mud from the plates, thus improving the practicality of the device.

[0012] Preferably, it also includes a rubber sleeve and a tension spring. The lower part of the separating shovel is fitted with a rubber sleeve, and the top of the drive rod is connected to the adjacent surface of the rectangular groove of the transverse platform by a tension spring. The rubber sleeve reduces the scratches between the separating shovel and the plates during the sludge scraping process. After the conical plate is pulled out from between the plates by the tension spring, the tension spring applies a pulling force to the drive rod to make the separating shovel automatically return to the groove of the conical plate, which improves the practicality of the device and enables the equipment to operate continuously.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the equipment is moved by the transverse moving device, the plates are separated in sequence by the separating device, and the mud pieces in the plates are separated from the plates by the mud scraping device, so that the mud pieces fall off normally, which reduces the labor intensity of the operators and improves the practicality of the device.

[0022] First, the motor 6 is turned on, and the power is transmitted to the two sets of lead screws 4 through the dual output reducer 5, which drives the two sets of lead screws 4 to rotate. The rotating lead screws 4, together with the nut 8, drive the transverse platform 7 to move back and forth between the plates 3. Then, the electric cylinder 9 is controlled to extend so that the lower part of the conical plate 10 is inserted between the two sets of adjacent plates 3 through the chamfer 11 of the two sets of adjacent plates 3, separating the connected plates 3. Then, as the conical plate 10 continues to move downward, the plates 3 contact the drive rod 16 and push the drive rod 16 to rotate, which in turn drives the separating shovel 15 to rotate, so that the separating shovel 15 separates from the groove on the conical plate 10. Then, the separating shovel 15 rotates to contact the plates 3 and separates the mud plates on the plates 3.

[0023] The transverse movement device includes a lead screw 4, a dual-output reducer 5, a motor 6, a transverse movement platform 7, and a nut 8.

[0025] It also includes a vibration motor 12, and a rectangular hole is provided in the middle of the conical plate 10. The vibration motor 12 is installed on the upper surface of the rectangular hole of the conical plate 10.

[0026] It also includes limiting light rods 13. A set of limiting light rods 13 is provided on the left and right sides of the upper end face of the conical plate 10. Both sets of limiting light rods 13 extend through the transverse platform 7 to the upper side of the transverse platform 7.

[0027] The sludge scraping device includes a rotating shaft 14, a separating shovel 15, and a drive rod 16. The left and right sides of the front and rear sides of the conical plate 10 are respectively provided with a set of grooves. The four sets of separating shovels 15 are respectively installed in the four sets of grooves of the conical plate 10 through the rotating shaft 14. The upper part of the separating shovel 15 is provided with a drive rod 16. The drive rod 16 extends to the outside of the conical plate 10 and the angle between it and the horizontal plane is smaller than the angle between the front and rear end faces of the conical plate 10 and the horizontal plane.

[0029] The equipment is moved by the transverse movement device, and the separation device separates the plates 3 in sequence. The mud scraper separates the mud pieces from the plates 3, allowing the mud pieces to fall off normally. This reduces the labor intensity of the operators and improves the practicality of the equipment.

[0030] like Figures 1 to 4 As shown, the filter pressing mechanism of the plate and frame filter press of this utility model, when working, firstly, the motor 6 is turned on and the power is transmitted to two sets of lead screws 4 through the double output reducer 5 to drive the two sets of lead screws 4 to rotate. The rotating lead screws 4, together with the nut 8, drive the transverse platform 7 to move back and forth between the plates 3. Then, the electric cylinder 9 is controlled to extend so that the lower part of the conical plate 10 is inserted between the two sets of adjacent plates 3 through the chamfer 11 of the two sets of adjacent plates 3, separating the connected plates 3. Then, as the conical plate 10 continues to move downward, the plates 3 contact the drive rod 16 and push the drive rod 16 to rotate, which in turn drives the separating shovel 15 to rotate, so that the separating shovel 15 separates from the groove on the conical plate 10. Then, the separating shovel 15 rotates to contact the plates 3 and separates the mud plates on the plates 3.
