Description

Technical Field

[0001] This utility model belongs to the field of plate and frame filter presses and relates to a device for quickly replacing filter cloth in plate and frame filter presses. Background Technology

[0002] This utility model belongs to the field of tool modification and optimization application technology. Specifically, it is a practical modification for a plate and frame filter press located on the second floor of a wastewater treatment building. In this scenario, the lower part of the plate and frame filter press is directly connected to a cake hopper for storing the treated cake. While this design effectively utilizes space, it presents considerable challenges to operators during actual operation, especially when replacing the filter cloth—a core component of the plate and frame filter press.

[0003] Because the filter plates in a plate and frame filter press are tightly packed with narrow gaps, it is difficult for workers to directly enter the interior to operate the filter. Traditional replacement methods require workers to lean out and drag the filter cloth by extending their arms. This method is not only extremely inconvenient, but more importantly, workers often lose their balance while leaning out, leading to instability and significantly increasing the risk of accidents.

[0004] To address this challenge, a rather rudimentary alternative has been adopted: a simple tool for replacing filter cloths. This tool primarily consists of a steel pipe and a rope. To use it, the rope is threaded in two strands through the steel pipe, one end is tied into a loop to secure the filter cloth, and the other end protrudes outside the pipe for the worker to pull. While this simple tool alleviates the difficulty of direct, inefficient operation to some extent, its rudimentary design makes the process still quite laborious and inefficient, and it offers limited improvement in operational safety.

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] The following is in conjunction with the appendix Figure 1 To be continued Figure 4 The present invention will be described in detail with reference to specific embodiments:

[0027] refer to Figure 1 , 2 A device for quickly replacing filter cloth in a plate and frame filter press includes a handle 1, one end of which is connected to an mounting plate 2. The surface of the mounting plate 2 is provided with a strip-shaped groove 3. Two sliders 4 of the same size are slidably connected in the groove 3. The surface of the sliders 4 is fixed with claws 5 for clamping filter cloth and other items.

[0028] The top of the grip 1 has a mounting cavity, inside which a servo motor 6 is installed. The output end of the servo motor 6 passes through the mounting plate 2, and a drive rod 7 is horizontally fixed to the output end. The installation position of the output end is located at the midpoint of the drive rod 7. A connecting rod 8 is hinged to each end of the drive rod 7. One end of each connecting rod 8 is hinged to the drive rod 7, and the other end is hinged to the slider 4.

[0029] Initially, the drive rod 7 and the two connecting rods 8 are in the same straight line. When the servo motor is started, the drive rod 7 rotates. The two ends of the drive rod 7 pull one end of the connecting rod 8 away from the straight line of the initial position. The other end of the connecting rod 8 pulls the slider 8, and the distance between the two sliders 8 decreases accordingly. The two grippers 5 begin to close and clamp the item between the grippers 5.

[0030] A button 9 is provided on the surface of the grip 1, and the button 9 is electrically connected to the servo motor. The button 9 controls the rotation direction of the servo motor output shaft, thereby realizing the opening or closing function of the gripper 5. This design makes operation simpler and faster, and improves work efficiency.

[0031] It also includes a support rod 10, which is connected to the outer wall of the handle 1, and the bottom end of the support rod 10 is fixed to the ground. The support rod 10 plays the role of a fixed fulcrum, effectively replacing the lever fulcrum function that was originally borne by the arm in the dragging action, thus making the dragging process more effortless and convenient.

[0032] Example 1

[0033] This embodiment provides a device for quickly replacing the filter cloth of a plate and frame filter press. The support rod 10 has a radially opened channel, through which the handle 1 passes. A gear 11 is provided on the top and bottom surfaces of the channel, and the outer wall of the handle 1 is provided with serrations 12. The handle 1 is inserted between the two gears 11, and the serrations of the handle 1 mesh with the gears 11.

[0034] Through the meshing connection between the serration 12 and the gear 11, the operator can quickly and easily fix or release the handle 1. After the gripper 5 clamps the filter cloth, the handle 1 can be pushed forward or pulled backward to remove the filter cloth from the plate frame.

[0035] The bottom end of the support rod 10 is rotatably connected to the surface of the base 13. The precise meshing of the serrations 12 and the gear 11 ensures the stability of the handle 1 in a fixed position. By rotating the support rod 10, the filter cloth can be dragged out of the plate frame.

[0036] The lower surface of the base 13 is provided with an anti-slip pad 14, which helps to prevent accidents caused by the movement of the handle 1 during filter cloth replacement, thereby improving the safety of operation.

[0037] The working process of the quick-change filter cloth device for plate and frame filter presses provided in this embodiment is as follows: First, the operator installs the support rod 10 on the base 13 and ensures that the support rod 10 can rotate stably on the base. Next, the operator inserts the handle 1 through the channel on the support rod 10 and ensures that the serrations 12 on the handle 1 are correctly engaged with the two gears 11.

[0038] By adjusting the position of the handle 1 so that its serrations mesh tightly with the gear 11, the handle 1 is fixed, and the gripper 5 is used to clamp the filter cloth to be replaced. Once the gripper 5 has clamped the filter cloth, the operator can move the filter cloth by pushing forward or pulling backward on the handle 1. If it is necessary to drag the filter cloth out of the plate frame, the operator can fix the position of the handle 1 and then rotate the support rod 10. Due to the rotatable connection between the support rod 10 and the base 13, this rotation can smoothly remove the filter cloth from the plate frame.

[0039] In summary, this embodiment utilizes the meshing connection of saw teeth and gears, allowing operators to quickly and easily secure or release the lever, thus significantly reducing the time required to change the filter cloth. Furthermore, the device's design enables operators to replace the filter cloth simply by pushing, pulling, and rotating, eliminating the need for complex operating procedures.

[0040] Example 2

[0041] The embodiment provides a device for quickly replacing the filter cloth of a plate and frame filter press. A universal ball joint 15 is mounted at the top of the support rod 10, and the outer wall of the handle 1 is rotatably connected to the support rod 10 via the universal ball joint 15. The handle 1 can rotate at any angle on the support rod 10, allowing the filter cloth to be dragged outwards from the plate and frame.

[0042] The bottom end of the support rod 10 is fixed to the surface of the base 13. The bottom of the base 13 is equipped with casters 16. By moving the base, the handle 1 can be pushed forward or pulled backward to remove the filter cloth from the plate frame.

[0043] The working process of the quick-change filter cloth device for plate and frame filter press provided in this embodiment is as follows: Assemble the device completely, ensuring that the top universal ball joint 15 of the support rod 10 is firmly connected to the outer wall of the handle 1, and the bottom end of the support rod 10 is firmly fixed to the base 13. By pushing or pulling the universal wheels 16 on the base 13, move the device to the vicinity of the plate and frame filter press where the filter cloth needs to be replaced. Use the gripper 5 to clamp the filter cloth to be replaced. Once the gripper 5 has clamped the filter cloth, hold the handle 1 and use the rotation connection of the universal ball joint 15 to drag the filter cloth outward from the plate and frame. During the dragging process, the angle of the handle 1 can be adjusted as needed to ensure that the filter cloth can be smoothly removed from the plate and frame.

[0044] In summary, this device, through the design of the universal ball joint 15 and universal wheels 16, allows operators to quickly adjust the angle and position of the handle 1, thereby rapidly replacing the filter cloth. Furthermore, the device's structural design enables operators to replace the filter cloth with simple pushing, pulling, and adjusting actions, eliminating the need for complex operating procedures.
