Description

Technical Field

[0001] This utility model relates to the technical field of equipment related to filter press repair and maintenance, and more specifically, to a filter press cloth clamping device installation tool. Background Technology

[0002] A filter press is a mechanical device that uses a special filter medium to allow liquid to separate, primarily for solid-liquid separation. It is widely used in industries such as chemical production, food processing, and wastewater treatment. A filter press consists of filter plates, and typically, a cloth clamp is installed on the feed hole of the filter plate. The main function of this device (cloth clamp) is to fix the filter cloth and ensure the sealing of the filter press system, thereby improving filtration efficiency and feed stability.

[0003] Common locking structures for filter press cloth clamps include nut locking, flange locking, and clamp locking. Clamp locking primarily uses the interference fit between the inner and outer grooves of the two cloth clamps and an O-ring to achieve the purpose of locking the cloth clamp. During installation, maintenance personnel place wooden blocks on the cloth clamps and use the impact force of a hammer to lock them in place. However, this method, due to the need for a hammer, is very prone to damaging the filter plates, cloth clamps, O-rings, and other spare parts. Furthermore, this method has low work efficiency and poor installation accuracy. Utility Model Content

[0033] Please refer to Figures 1 to 4 ,in, Figure 1 This is a schematic diagram of the structure of the filter press cloth clamping device installation tool in an embodiment of this utility model; Figure 2 This is a schematic diagram of the structure of the pull plate in an embodiment of this utility model; Figure 3 This is a schematic diagram of the filter press cloth clamping tool in use (not assembled onto the cloth clamping device) in an embodiment of the present utility model. Figure 4This is a structural diagram of the filter press cloth clamping tool in use (when it has been assembled onto the cloth clamping device) in an embodiment of this utility model.

[0034] This utility model provides a filter press cloth clamping device installation tool. The installation tool can apply pressure and tension to the cloth clamping device from both sides (one side of the inner cylinder 3 and one side of the outer cylinder 5, with the inner cylinder 3 and the outer cylinder 5 installed on the filter plate 4), thereby assembling the inner and outer cylinders of the cloth clamping device together.

[0035] In this invention, the filter press cloth clamping device installation tool comprises three main structural components: a screw 1, a pressure plate 2, and a pull plate 6. The pressure plate 2 is a single integral component, while the pull plate 6, which passes through the cloth clamp, employs a multi-component structure. The pull plate 6 can be stowed when passing through the cloth clamp and unfolded afterward. Furthermore, the pull plate 6 is fixed relative to the axis of the screw 1 (the pull plate 6 and the screw 1 are rotatably coupled), while the pressure plate 2 can move axially relative to the screw 1. Further, stop structures are provided on the screw 1 at both ends of the external thread 13. These stop structures can be retaining rings or protrusions, used to limit the movement of the pressure plate 2.

[0036] In this invention, the lead screw 1 is a long, straight, round rod structure, preferably made of stainless steel. The relative spacing between the pressure plate 2 and the pull plate 6 is designed based on the minimum thickness of the fabric clamp (the final thickness after the inner cylinder 3 and outer cylinder 5 of the fabric clamp are assembled together). Specifically, after the pressure plate 2 moves to its limit position on the lead screw 1, the minimum gap between the pressure plate 2 and the pull plate 6 is not greater than (can be equal to or slightly less than) the minimum thickness of the fabric clamp. The external thread 13 (either a partial section of the lead screw 1 or the entire length of the lead screw 1) is designed according to this standard. During use, the lead screw 1 rotates while the pressure plate 2 does not, allowing the pressure plate 2 to move along the axial direction of the lead screw 1. Simultaneously, the pull plate 6 rotates with the lead screw 1 but its axial position remains unchanged.

[0037] To facilitate the easy rotation of the lead screw 1, this invention proposes the following design for the lead screw 1: 1. One end of the lead screw 1 is a screwing end 14, which has an end structure (or the screwing end 14 is designed as a specific structure). The end structure is a solid metal structure, preferably a cylindrical structure with a diameter not less than that of the lead screw 1. The end structure is coaxial with the lead screw 1, and a through hole 9 is provided on the end structure. The center line of the through hole 9 intersects with and is perpendicular to the center line of the lead screw 1; 2. One end of the lead screw 1 is a screwing end 14, on which a nut is fixedly installed, or a component with the same external contour structure as the nut is provided. For the first structural design, an additional solid rod is required during use. After passing the solid rod through the through hole 9 of the end structure, the rotation of the lead screw 1 can be easily achieved. For the second structural design, this invention can use an electric device. After the nut is fitted with an internal hexagonal socket, the rotation of the lead screw 1 is achieved by mechanical drive. Of course, other structures, such as universal joints, can also be provided at the screw end 14 of the lead screw 1 to achieve power connection with mechanical equipment.

[0038] The pressure plate 2 is made of a rigid material, and its structural strength should ensure that it does not deform when pressure is applied to the fabric clamp. Preferably, the pressure plate 2 in this invention is made of metal. The pressure plate 2 is used to contact the outer cylinder 5 or the inner cylinder 3 of the fabric clamp (when the pressure plate 2 is in contact with the outer cylinder 5, the pull plate 6 is in contact with the inner cylinder 3; when the pressure plate 2 is in contact with the inner cylinder 3, the pull plate 6 is in contact with the outer cylinder 5). The pressure plate 2 is threaded with the lead screw 1 13, and the pressure plate 2 can move axially along the lead screw 1 while the lead screw 1 is rotating. The pressure plate 2 is used to apply a clamping force to the outside.

[0039] In one specific embodiment of this utility model, the pressure plate 2 has a centrally symmetrical structure, with a threaded hole at the center of symmetry, and an external thread 13 on the outer side of the lead screw 1. The pressure plate 2 can be designed as a disc, elliptical disc, rectangular plate, or spoke structure. In use, a pressure platform is provided on the side of the pressure plate 2 facing the fabric clamp, and the pressure platform has a planar contact structure with the inner cylinder 3 or outer cylinder 5 of the fabric clamp. Furthermore, this utility model can also provide a rubber or plastic pad at the part of the pressure plate 2 that contacts the fabric clamp, thereby providing structural protection for the fabric clamp.

[0040] The pull plate 6 is assembled from the pull plate body and the pull plate accessory 7. In this utility model, both the pull plate body and the pull plate accessory 7 are made of rigid materials. The structural strength of the pull plate 6 and the pull plate accessory 7 should ensure that the pull plate accessory 7 does not deform when pressure is applied to the fabric clamp. The pull plate 6 can be rotatably engaged with the lead screw 1 at a fixed position (preferably the other end of the lead screw 1, or understood as the tail end of the lead screw 1). As can be seen from the above, one end of the lead screw 1 (which can be understood as the head end) is the screwing end 14, which is used to drive the lead screw 1 to rotate. In order to realize the installation of the pull plate 6, an installation ring groove is provided at the other end of the lead screw 1. The pull plate 6 is set in the installation ring groove through the center hole. A baffle 8 is provided on the end face of the other end of the lead screw 1. Through the structure of the installation ring groove and the baffle 8, the axial positioning of the pull plate 6 on the lead screw 1 can be realized, preventing the pull plate 6 from axially moving on the lead screw 1. At the same time, the pull plate 6 and the lead screw 1 can also maintain a rotational fit (when the lead screw 1 rotates to drive the pressure plate 2 to move axially, the pull plate 6 can also remain relatively stationary with the fabric clamp).

[0041] Since the pull plate 6 needs to pass through the fabric clamp and also needs to pull the fabric clamp, the present invention proposes the following structural design for the pull plate 6: a pull plate attachment 7 is provided on the pull plate 6, and the pull plate attachment 7 is hinged to the pull plate 6. The pull plate 6 is used to exert a tensioning force on the external support. Specifically, the pull plate 6 and the pull plate attachment 7 are configured such that, at least after the pull plate attachment 7 is unfolded, the widest dimension of the pull plate attachment 7 and the pull plate 6 is greater than the inner diameter of the outer cylinder 5 or the inner cylinder 3 of the fabric clamp, and at least after the pull plate attachment 7 is retracted, the widest dimension of the pull plate attachment 7 and the pull plate 6 is less than the inner diameter of the outer cylinder 5 or the inner cylinder 3 of the fabric clamp. The pull plate attachment 7 can rotate 90° relative to the pull plate 6. At the two extreme rotation positions of the pull plate attachment 7, the pull plate attachment 7 can be parallel to or perpendicular to the lead screw 1. When the pull plate attachment 7 is parallel to the lead screw 1 (in the retracted state), the entire pull plate 6 assembly can pass through the fabric clamp. After passing through the fabric clamp, the pull plate attachment 7 rotates 90° and is perpendicular to the lead screw 1. Then the entire pull plate 6 assembly can be locked on the fabric clamp and exert a pulling force on the fabric clamp bracket.

[0042] Specifically, the pull plate 6 has a centrally symmetrical structure. The pull plate 6 can be circular or spoke-shaped. A central hole is provided at the center of symmetry of the pull plate 6, and the pull plate 6 is rotatably mounted on the lead screw 1 through the central hole. At least two mounting slots are provided on the outer edge of the pull plate 6. All the mounting slots are equally spaced around the center of symmetry of the pull plate 6. The pull plate accessory 7 is hinged to the mounting slots by fixing nails 10.

[0043] To enable the pull plate accessory 7 to rotate within the mounting slot (allowing only 90° rotation and stopping rotation in a set state), this utility model optimizes the mounting slot on the pull plate accessory 7 or pull plate 6 as follows: 1. One end of the pull plate accessory 7 is a hinged end, which is set in the mounting slot. In the unfolded state of the pull plate accessory 7, the top corner of the hinged end facing the pressure plate 2 is a rounded corner structure (the rounded corner structure can avoid the rotation of the hinged end in the mounting slot), which is used to enable the pull plate accessory 7 to rotate towards the pressure plate 2; the end face of the hinged end includes at least a flat structure, which is used to abut against the bottom of the mounting slot after the pull plate accessory 7 is unfolded to limit the rotation of the pull plate accessory 7; 2. The side of the mounting slot facing the pressure plate 2 is an open structure, which is used to enable the pull plate 6 to rotate towards the pressure plate 2; the side of the mounting slot facing away from the pressure plate 2 is a closed structure, which is used to limit the rotation of the pull plate 6 when it rotates away from the pressure plate 2.

[0044] The installation tool provided by this utility model is made of steel and mainly consists of a pressure plate 2, a pull plate 6, and a lead screw 1. The lead screw 1 and pressure plate 2 are machined with external and internal threads, respectively, and the lead screw 1 and pressure plate 2 are connected by a thread 13. The front end of the lead screw 1 is a screw-in end 14 with a through hole for inserting a round steel bar, facilitating rotation of the lead screw and increasing torque. The end of the pull plate 6 has a through hole 9, and a baffle 8 at the end of the lead screw 1 limits the pull plate 6. The pull plate 6 and the lead screw 1 are in clearance fit, and the pull plate 6 can rotate on the upper part of the lead screw. The pull plate accessory 7 is fixed to the pull plate 6 by a fixing nail 10, and the pull plate accessory 7 and the pull plate 6 are hinged, allowing them to rotate 90° around the fixing nail 10. Before use, the inner cylinder 3 and outer cylinder 5 of the cloth clamp are installed on the filter plate 4 to tighten the filter cloth. The inner cylinder 3 and outer cylinder 5 of the fabric clamp are connected by an O-ring 12 to the inner groove 11 of the outer cylinder 5. When the O-ring 12 enters the inner groove 11, the inner cylinder 3 and outer cylinder 5 are installed in place. In use, the tool rotates 90° between the pull plate attachment 7 and the pull plate 6 (the pull plate attachment 7 is parallel to the lead screw 1). Then, the tool passes through the fabric clamp, rotating the pull plate attachment 7 and pull plate 6 into a straight line (the pull plate attachment 7 is perpendicular to the lead screw 1). Then, the pull plate attachment 7 is pressed tightly against the outer cylinder 5. By turning the screw screw 14, the pull plate 2 approaches and presses against the inner cylinder 3 until the O-ring 12 enters the inner groove 11, thus installing the inner cylinder 3 and outer cylinder 5. Alternatively, the turning end 14 can be made into a nut shape, allowing for connection to a power tool to speed up the turning process and improve installation efficiency.

[0045] This invention utilizes the puller principle. By rotating the lead screw, pressure is generated between the pressure plate and the pull plate. This pressure is transmitted between the inner and outer sleeves of the fabric clamp, achieving nesting and assembly between them, thus meeting on-site inspection and maintenance requirements. The beneficial effects of this invention are: it improves the installation efficiency of fabric clamps for maintenance personnel and reduces their workload. Furthermore, it reduces the risk of damage to fabric clamps and other spare parts during installation, increases installation efficiency and equipment availability, and lowers spare parts costs and installation expenses.

[0046] After this utility model is put into use, the deep treatment system in the work area has two filter presses that use clamp-type locking cloth clamps. Maintenance personnel, lacking specialized tools, used wooden blocks and hammers to strike the clamps when reinstalling them, which damaged the clamps or diaphragms. Assuming the filter cloth is replaced twice a year, each filter press has 50 clamps. During the annual filter cloth replacement, at least one clamp and one diaphragm are damaged for every two filter presses. Using this tool effectively avoids the damage to these spare parts. A diaphragm costs approximately 10,000 yuan, and a clamp costs approximately 400 yuan, resulting in annual savings of approximately 10,400 yuan in spare parts costs. Using this tool will reduce the installation time for each set of filter cloth by approximately 4 hours, requiring a total of 3 on-site maintenance personnel. The annual cost savings are approximately 4 × 486 × 3 = 5,832 yuan. Therefore, the annual savings are approximately 10,400 + 5,832 = 16,232 yuan.

[0047] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
