Description

Technical Field

[0001] This utility model relates to the technical field of plate and frame filter press mechanisms, specifically a split-type plate and frame filter press. Background Technology

[0002] When replacing filter cloth or disassembling filter plates in a plate and frame filter press, the filter plates need to be lifted from above using a hoisting mechanism. For stability reasons, only one filter plate can usually be hoisted at a time. This method is inefficient when disassembling multiple filter plates. If multiple filter plates are hoisted directly using wire ropes, the filter plates are prone to slippage and falling, causing damage. Furthermore, this method is not conducive to the tight arrangement of filter plates during installation. Utility Model Content

[0003] To address the issues of low efficiency and inability to position the filter plates correctly when directly hoisting them with wire ropes, this invention provides a split-type plate and frame filter press.

[0004] The technical solution of this utility model is as follows:

[0005] A split-type plate and frame filter includes a filter body, the filter body is provided with a guide rail arranged along the length direction, and multiple filter plates are arranged along the guide rail along the length direction. A pressure bearing mechanism and a pressing mechanism are respectively provided at both ends of the guide rail.

[0006] The guide rail includes a support rail fixed to the filter body, and multiple split lifting blocks are arranged above the support rail along the length of the guide rail. The filter plate is arranged above the split lifting blocks and can move. The split lifting blocks are inserted into the support rail in the vertical direction, and lifting mechanisms are provided at both ends of the split lifting blocks in the length direction.

[0007] By setting the original guide rail to two layers, multiple filter plates can be lifted simultaneously when lifting the split lifting block, resulting in higher efficiency.

[0008] The specific structure of the aforementioned split lifting block is as follows: the split lifting block includes a track assembly block that is vertically inserted into the support rail and lifting ropes set at both ends of the track assembly block.

[0009] To avoid affecting the movement of the filter plate, grooves are provided at both ends of the track assembly block, and the lifting rope is placed in the grooves.

[0010] To prevent the track assembly block from moving, the lower surface of the track assembly block is provided with multiple insertion parts spaced apart along the length direction.

[0011] The specific structure of the above-mentioned plug-in part is that the plug-in part is conical, and the support rail is provided with a conical plug-in interface.

[0012] To ensure the stability of the filter plate during the lifting process, the length of the track assembly block is a positive integer multiple of the filter plate thickness.

[0013] As a preferred embodiment, the end of the lifting rope away from the track assembly block is located on the side of the track assembly block away from the filter plate, and this end is provided with an opening.

[0014] As a preferred embodiment, the contact surface between the track assembly block and the filter plate is configured to mimic the shape of the filter plate.

[0015] To avoid misalignment of the filter plates, the filter plates can only move in their length direction relative to the track assembly block.

[0016] To ensure that the position of the filter plate remains constant after installation, one end of a split lifting block is flush with the contact surface between the pressure-bearing mechanism and the filter plate.

[0017] The beneficial effects of this utility model are as follows: This utility model is a split-type plate and frame filter. Based on the original structure, the guide rail is set as an upper and lower two-layer structure. While ensuring that its original function does not change, the filter plate is supported by split lifting blocks that are positive integer multiples of the filter plate thickness. Moreover, the split lifting blocks can be lifted after being equipped with lifting ropes. This method can replace the original lifting of individual filter plates. Instead, multiple filter plates are lifted at the same time by lifting the split lifting blocks. The disassembly and assembly efficiency is higher, the position of the filter plates is constant after installation, and the tight fit is relatively stable during movement, so it will not tip over.

[0029] Example

[0030] like Figure 1 The illustrated split-type plate and frame filter includes a filter body 1. The filter body 1 is provided with a guide rail arranged along the length direction, and multiple filter plates 2 are arranged along the guide rail along the length direction. A pressure bearing mechanism 4 and a pressing mechanism 3 are respectively provided at both ends of the guide rail. The movement of the pressing mechanism 3 can drive the filter plates 2 to move and cooperate with the pressure bearing mechanism 4 to press all the filter plates 2. Since its structure has not changed, it will not be described in detail.

[0031] The key feature of this device is that the guide rail includes a support rail 11 fixed to the filter body 1. The support rail 11 is horizontal and in a constant position for bearing weight. Furthermore, multiple separate lifting blocks 5 are arranged above the support rail 11 along the length of the guide rail. Figure 1 , 2 As shown, multiple split lifting blocks 5 combined with the support rail 11 form a complete guide rail structure. In order to ensure the normal use of the equipment, the filter plate 2 is set above the split lifting blocks 5 and can move. That is to say, the combination of the above structure does not affect the original guiding and supporting function. However, compared with the existing guide rail, the split lifting blocks 5 are inserted into the support rail 11 in the vertical direction. That is to say, after being subjected to an upward pulling force, the split lifting blocks 5 can separate from the support rail 11 and be lifted. For this purpose, lifting mechanisms are provided at both ends of the split lifting blocks 5 in the length direction. By fixing the two ends, the stability of the lifting can be ensured and the horizontal position can be maintained as much as possible.

[0032] After that, as Figure 3 , 6 As shown in Figure 7, the specific structure of the aforementioned split lifting block 5 is as follows: the split lifting block 5 includes a track assembly block 51 vertically inserted into the support rail 11 and lifting ropes 52 disposed at both ends of the track assembly block 51. The track assembly block 51 is fixedly connected to one end of the lifting rope 52, and the lifting rope 52 can be a thin steel wire rope. Furthermore, as shown in Figure 7... Figure 2-7 As shown, in order to avoid affecting the movement of the filter plate 2, the two ends of the track assembly block 51 are provided with grooves 511, and the lifting rope 52 is set in the grooves 511. Therefore, even if the lifting rope 52 is set, it will not bulge outward and thus affect the movement of the filter plate 2. It should be noted that the overall width of the grooves 511 of two adjacent track assembly blocks 51 is less than the thickness of the filter plate 2 support, so as to avoid obstruction during the movement.

[0033] Subsequently, to ensure the stability of the filter plate 2 during the lifting process, the length of the track assembly block 51 is a positive integer multiple of the thickness of the filter plate 2. That is, after the pressing mechanism 3 moves the filter plates 2 to a state of close contact, the aforementioned split lifting blocks 5 can align with the corresponding number of filter plates 2. Figure 2 As shown, multiple filter plates 2 can be lifted simultaneously using a hoisting structure and lifting rope 52, resulting in high assembly and disassembly efficiency.

[0034] Furthermore, to prevent the track assembly block 51 from moving, a plurality of insertion portions 512 are provided at intervals along the length of the lower surface of the track assembly block 51. The insertion portions 512 can be inserted and connected to the support rail 11 at corresponding positions, and their positions remain constant when not subjected to lifting force. The specific structure of the insertion portions 512 is that the insertion portions 512 are conical, and the support rail 11 is provided with a conical insertion interface. In this way, when installing the filter plate 2, it can be accurately fixed in the corresponding position without the need for a pushing and arranging process.

[0035] Moreover, as Figure 5 As shown, in a preferred embodiment, the contact surface between the track assembly block 51 and the filter plate 2 is contoured to ensure a tight fit. Furthermore, to prevent misalignment of the filter plate 2, the filter plate 2 can only move relative to the track assembly block 51 along its length. That is, the filter plate 2 cannot move perpendicular to the track length, thus ensuring the constant position of the filter plate 2. During assembly and disassembly, the position of the filter plate 2 remains constant relative to the track assembly block 51.

[0036] In addition to the above structure, to facilitate hoisting operations, in a preferred embodiment, the end of the lifting rope 52 away from the track assembly block 51 is located on the side of the track assembly block 51 away from the filter plate 2, and this end is provided with an opening. The hoisting device can then pass through the opening for hoisting.

[0037] Finally, that is, as Figure 1 , 2As shown, to ensure the filter plate 2 remains in a constant position after installation, one end of a split lifting block 5 is flush with the contact surface between the pressure-bearing mechanism 4 and the filter plate 2. In this way, after installation, the filter plate 2 can be tightly fitted to the pressure-bearing mechanism 4, and during the placement operation, the conical insertion part 512 facilitates guidance, allowing the track assembly block 51 to fall into a fixed preset position, thereby ensuring the filter plate 2 remains in a constant position after installation.

[0038] The above method allows for the simultaneous installation and removal of multiple filter plates 2 as needed, resulting in higher efficiency. This setup ensures the stability of the filter plates 2 during movement, and the position of the installed filter plates 2 is controllable. Conventionally, installing a single filter plate 2 requires pressing and pushing to ensure tight adhesion, but this method directly achieves a tight fit. Furthermore, each individual split lifting block 5 can be individually installed and removed, and its length can be changed to improve applicability according to actual needs.
