Description

Technical Field

[0001] This utility model relates to a split-type unloading system for a vertical filter press, which can improve the operational reliability of the filter press unloading system and belongs to the field of filter press technology. Background Technology

[0002] Vertical filter presses, also known as fully automatic filter cloth walking filter presses, typically have a discharge system consisting of multiple plates and frames and a filter cloth. The filter cloth is arranged in a zigzag pattern between the plates and frames, meaning it moves around multiple parallel plates and frames (e.g., ...). Figure 1 As shown in the diagram, the resistance of the filter cloth during unloading increases with the load on the filter cloth. Large filter presses have large filtration areas, long filter cloths, and heavy loads, resulting in very high tensile forces on the filter cloth during unloading. This often leads to filter cloth joint breakage, reducing equipment operating rates and increasing maintenance costs. Therefore, designing a highly reliable split-type unloading system for vertical filter presses is essential. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a split-type unloading system for vertical filter presses, thereby reducing malfunctions in the unloading system, improving equipment operating rates, and lowering equipment maintenance costs.

[0032] See Figure 3 , Figure 6 and Figure 7 One end of the support plate 3 is provided with a support plate keyway 302 and bolt holes, and is fixed to the end of the plate frame 1 by connecting bolts 301. A flat key is provided in the support plate keyway 302, and the support plate 3 is precisely positioned by the flat key, so as to achieve positional constraint between the unloading roller 5, the guide roller 6 and the plate frame 1. The other end of the support plate 3 is provided with an unloading roller mounting hole 303 and a guide roller mounting hole 304 for mounting the unloading roller 5 and the guide roller 6. The function of the unloading roller 5 is to wind up the filter cloth 10 during the unloading process. The unloading roller 5 is powered by the unloading hydraulic motor 2, and the unloading action is achieved by winding up the filter cloth 10 layer by layer. The guide roller 6 is installed on the outside of the unloading roller 5. Its function is to redirect the filter cloth 10, so that the filter residue on the upper part of the filter cloth 10 is transferred to the lower part of the filter cloth 10, and then falls off under its own gravity.

[0033] See Figure 3 , Figure 4 and Figure 5 One end of the connecting plate 4 is provided with a connecting plate keyway 402 and a bolt hole, and is fixed to the end of the plate frame 1 by connecting bolts.

One end of the filter cloth 10 enters the unloading roller 5 through this slot and is fixedly connected to the filter cloth fixing rod 501. When the unloading roller 5 rotates, the filter cloth 10 is constrained by the filter cloth fixing rod 501 and gradually wraps around the unloading roller 5. The unloading roller 5 is rotatably connected to the support plate 3 via an unloading roller bearing 505. Unloading roller sealing grooves 502 are provided at the shoulders of both ends of the unloading roller 5 for installing rubber sealing rings 504 to prevent water ingress into the bearings.

Both the output shaft of the unloading hydraulic motor 2 and the journal of the transmission end of the unloading roller 5 are provided with keyways. They are connected to the transmission tube 506 via a flat key 201 and a flat key 503 of the unloading roller, respectively. The transmission tube 506 transmits the power of the self-unloading hydraulic motor 2 to the unloading roller 5 via the flat key 201 and the flat key 503 of the unloading roller.

[0035] See Figure 4 The reset roller 7 has a hollow structure with a filter cloth fixing shaft 701 inside. Each side of the reset roller 7 has a rectangular slot. One slot is wider than the diameter of the filter cloth fixing shaft 701, allowing the shaft to be inserted. The other slot is narrower than the shaft diameter. One end of the filter cloth 10 enters the reset roller 7 through this slot and is fixedly connected to the filter cloth fixing shaft 701. When the reset roller 7 rotates, the filter cloth 10 is constrained by the filter cloth fixing shaft 701 and wraps around the reset roller 7 layer by layer. The reset roller 7 is rotatably connected to the connecting plate 4 via a reset roller bearing 706. Reset roller sealing grooves 702 are provided at the shoulders of both ends of the reset roller 7 for installing O-ring seals 703 to prevent water ingress into the bearing. The housing of the reset hydraulic motor 8 is fixedly connected to the connecting plate 4 via a shorting sleeve 708. The shorting sleeve 708 and the connecting plate 4 are connected by shorting bolts. The shorting sleeve 708 and the housing of the reset hydraulic motor 8 are connected by fixing bolts. The output shaft of the reset hydraulic motor 8 is connected to the journal of the transmission end of the reset roller 7 via a transmission sleeve 707 that passes through the shorting sleeve 708. Both the output shaft of the reset hydraulic motor 8 and the journal of the transmission end of the reset roller 7 are provided with keyways. They are connected to the transmission sleeve 707 via a reset motor key 801 and a reset roller key 705, respectively. The transmission sleeve 707 transmits the power of the self-resetting hydraulic motor 8 to the reset roller 7 via the reset motor key 801 and the reset roller key 705.

[0036] The assembly and use methods of this utility model are as follows:

[0037] The flat key is installed in the keyway 302 of the support plate, and then the support plate 3 is fixed to both sides of the end of the plate frame 1 with bolts. The constraint of the flat key can ensure the positional accuracy of the guide roller 6 and the plate frame 1, and prevent the filter cloth from running off-center due to roller misalignment.

[0038] Install the rubber sealing ring 504 in the unloading roller sealing groove 502 on the shoulder of the unloading roller 5, and then insert the unloading roller 5 into the unloading roller mounting hole 303 on the support plate 3.

[0039] Install the unloading roller bearing 505 on the journal of the drive end of the unloading roller 5, and install the unloading roller flat key 503 in the keyway of the journal. Install the flat key 201 in the keyway of the output shaft of the unloading hydraulic motor 2, and then install the drive tube 506 on the journal of the output shaft of the unloading hydraulic motor 2. The short connector 507 is connected to the unloading hydraulic motor 2 via a female-female joint and a fixing bolt. Rotate the drive tube 506 so that its keyway corresponds to the unloading roller flat key 503 on the journal of the unloading roller 5, and connect them. Fix the short connector 507 to the support plate 3 with the short connector bolt 508.

[0040] Install the unloading roller bearing 505 on the journal of the free end of the unloading roller 5, and fix the end cover 601 to the support plate 3 on the other side of the plate frame 1 with bolts.

[0041] Install the sealing rings in the sealing grooves of the shoulders at both ends of the guide roller 6, and then insert the guide roller 6 into the guide roller mounting holes 304 on the support plate 3. Install the bearings on the journals at both ends of the guide roller 6, and install the end caps. The guide roller is a free roller.

[0042] The installation method of the reset roller 7 is the same as that of the unloading roller 5, except that the reset roller 7 is installed at the other end of the plate frame 1, and the reset hydraulic motor 8 and the unloading hydraulic motor 2 are installed at the same diagonal ends of the plate frame 1.

[0043] Both ends of the filter cloth 10 are provided with fixing sleeves. One fixing sleeve passes around the guide roller 6 and enters the narrow slot on one side of the unloading roller 5 and exits through the wide slot. The filter cloth fixing rod 501 is inserted into the filter cloth fixing sleeve, and then the filter cloth 10 is pulled to constrain the filter cloth fixing rod 501 in the roller body of the unloading roller 5. The other fixing sleeve of the filter cloth 10 is also inserted into the narrow slot of the reset roller 7 and constrains the filter cloth fixing shaft 701 in the roller body of the reset roller 7.

[0044] When the vertical filter press is unloading, the plates and frames 1 are pulled apart to maximize the distance between them. The unloading hydraulic motor 2 rotates, driving the unloading roller 5 to rotate. At this time, the reset roller 7 and guide roller 6 are driven. Because the filter cloth 10 is constrained by the filter cloth fixing rod 501 in the unloading roller 5, the filter cloth 10 moves horizontally as the unloading roller 5 rotates. The filter residue on the filter cloth 10 moves to the guide roller 6 and falls off under its own gravity. After unloading, the filter cloth 10 is wrapped around the unloading roller 5 layer by layer. After the material is unloaded, the reset hydraulic motor 8 rotates, driving the reset roller 7 to rotate. At this time, the unloading roller 5 and guide roller 6 are driven. The filter cloth 10 is gradually wrapped around the reset roller 7 due to the constraint of the filter cloth fixing shaft 701 in the reset roller 7, realizing the reset action of the filter cloth 10. When all plates and frames have completed the unloading and reset actions, the vertical filter press can start the next production cycle.
