Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically a multi-tube modular closed slurry filtration device. Background Technology

[0002] Slurry is a liquid mixture containing solid particles and appears in many industrial production and engineering applications. For example, in the chemical industry, some chemical reactions may produce products in slurry form; in the mining industry, after ore is processed by grinding and other preliminary processes, a slurry containing mineral powder is formed. Slurry filtration devices are used to separate the solid particles and liquid in the slurry.

[0003] In the existing technology, filtration devices for slurries still have drawbacks such as poor separation effect, easy clogging failure, and inconvenience in maintenance and replacement. Utility Model Content

[0004] The purpose of this invention is to provide a multi-tube modular closed slurry filtration device that has high filtration efficiency and is easy to inspect and replace.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multi-tube modular closed slurry filtration device includes a slurry filtration closed shell, and multiple horizontally arranged filter module support tubes are provided inside the slurry filtration closed shell. Multiple slurry filter plates with internal and external communication are installed on the side walls of the filter module support tubes.

[0007] Multiple clear liquid discharge pipes are fixed to the outer wall of the slurry filter enclosure. One end of each clear liquid discharge pipe extends into the slurry filter enclosure and is fitted with an end-sealing constraint pipe. Multiple filter module support pipes are coaxially fitted into each end-sealing constraint pipe and connected to the clear liquid discharge pipes.

[0008] Preferably, the outer wall of the slurry filter enclosure is fixed with multiple slurry inlet pipes that communicate with its interior, and the bottom of the slurry filter enclosure is fixed with multiple slurry discharge pipes that communicate with its interior.

[0009] Note: The multiple slurry inlet pipes and multiple slurry discharge pipes are all controlled by independent valves to open and close, which facilitates the adjustment and control of the input and output flow rates.

[0010] Preferably, the side wall of the filter module support pipe has multiple slurry filtration channels that are interconnected internally and externally. The inner side wall of the slurry filtration channel has a ring of filter plate mounting grooves, and the edge of the slurry filter plate is fixedly constrained in the filter plate mounting grooves.

[0011] Note: The modular assembly of slurry filter plates facilitates maintenance and replacement. When one slurry filter plate becomes clogged, the overall filtration effect is minimally affected.

[0012] Preferably, a filter tube constraint mechanism is provided on the side wall opposite to the multiple clear liquid discharge pipes of the slurry filter enclosure. The filter tube constraint mechanism includes multiple filter tube constraint support cylinders fixed on the outer side wall of the slurry filter enclosure. The multiple filter tube constraint support cylinders are arranged coaxially with each filter module support pipe. The side wall of the slurry filter enclosure has a sliding cylinder mating hole that communicates with the filter tube constraint support cylinder.

[0013] A filter tube constraint sliding cylinder with an outward opening is slidably connected inside the filter tube constraint support cylinder. The outer end of the filter tube constraint sliding cylinder extends through the sliding cylinder mating hole into the slurry filtration closed shell.

[0014] One end of the filter tube constraint sliding cylinder extending into the slurry filtration closed shell is fixed with an end constraint shell coaxial with the filter module support tube, and the end constraint shell is sleeved on the end of the filter module support tube.

[0015] Note: The filter tube constraint mechanism can firmly constrain and fix the filter module support tube inside the slurry filter enclosure, and facilitates the overall disassembly and replacement of the filter module support tube through the filter tube constraint mechanism.

[0016] Preferably, a drive mating column is fixed inside the filter tube constraint sliding cylinder. The drive mating column has a drive mating threaded hole that runs through the axis of the filter tube constraint sliding cylinder. A constraint drive threaded rod is threadedly connected inside the drive mating threaded hole. A constraint drive receiving shell is fixed at the outer end of the filter tube constraint support cylinder. One end of the constraint drive threaded rod extends into the constraint drive receiving shell. A constraint drive motor for driving the constraint drive threaded rod to rotate is fixed inside the constraint drive receiving shell.

[0017] Note: The threaded transmission between the constraint drive threaded rod and the drive mating column has self-locking properties, which can effectively prevent the filter module support tube from loosening during operation.

[0018] Compared with the prior art, the beneficial effects of this utility model are reflected in the following aspects:

[0019] 1. The present invention has a reasonable structural design. Multiple filter module support tubes are integrated together, which can filter a large amount of slurry at the same time. The multiple filter module support tubes can work in parallel, which can process more slurry per unit time compared with single tube filtration equipment.

[0020] 2. This utility model is easy to maintain and replace parts. Each filter module support tube can be maintained or replaced relatively independently. When one of the filter module support tubes is blocked or damaged, it has little impact on the operation of the entire device. Only the filter module support tube with the problem needs to be replaced.

[0021] 3. Because this utility model is a closed system, the slurry is confined inside the device during the filtration process and will not easily leak into the external environment. The closed environment can reduce the interference of external factors on the filtration process, such as dust and impurities, ensuring the accuracy and quality of filtration and making the filtered liquid purer.

[0028] Example 1:

[0029] A multi-tube modular closed-loop slurry filtration device, such as Figure 1As shown, it includes a slurry filter enclosure 10, and multiple horizontally arranged filter module support pipes 11 are provided inside the slurry filter enclosure 10. Multiple slurry filter plates 110 with internal and external communication are installed on the side wall of the filter module support pipes 11.

[0030] Multiple clear liquid discharge pipes 12 are fixed on the outer wall of the slurry filter enclosure 10. One end of the multiple clear liquid discharge pipes 12 extending into the slurry filter enclosure 10 is fitted with an end sealing constraint pipe 120. Multiple filter module support pipes 11 are coaxially fitted in each end sealing constraint pipe 120 and connected to the clear liquid discharge pipes 12.

[0031] like Figure 2 As shown, multiple slurry inlet pipes 101 connected to the interior are fixed on the outer wall of the slurry filter enclosure 10, and multiple slurry discharge pipes 102 connected to the interior are fixed on the bottom of the slurry filter enclosure 10.

[0032] like Figure 3 As shown, the side wall of the filter module support pipe 11 has multiple slurry filtration channels 111 that are interconnected internally and externally. The inner side wall of the slurry filtration channel 111 has a ring of filter plate mounting grooves 112. The edge of the slurry filter plate 110 is fixedly constrained in the filter plate mounting grooves 112.

[0033] The slurry filter plate 110 is a commercially available 400-mesh filter plate of the prior art.

[0034] Example 2:

[0035] Based on Example 1, such as Figure 4 As shown, a filter tube constraint mechanism 13 is provided on the side wall opposite to the multiple clear liquid discharge pipes 12 of the slurry filter closed shell 10. The filter tube constraint mechanism 13 includes multiple filter tube constraint support cylinders 131 fixed on the outer side wall of the slurry filter closed shell 10. The multiple filter tube constraint support cylinders 131 are arranged coaxially with each filter module support pipe 11. The side wall of the slurry filter closed shell 10 has a sliding cylinder mating hole 1310 that communicates with the filter tube constraint support cylinder 131.

[0036] One end of the filter tube constraint support cylinder 131 is open and the opening faces the inside of the slurry filtration closed shell 10.

[0037] A filter tube constraint sliding cylinder 132 with an outward opening is slidably connected inside the filter tube constraint support cylinder 131. The outer end of the filter tube constraint sliding cylinder 132 extends through the sliding cylinder mating hole 1310 into the interior of the slurry filtration closed shell 10.

[0038] The filter tube constraint sliding cylinder 132 extends into the slurry filter closed shell 10. One end of the cylinder is fixed with an end constraint shell 133 that is coaxial with the filter module support tube 11. The end constraint shell 133 is sleeved on the end of the filter module support tube 11.

[0039] Example 3:

[0040] Based on Example 2, such as Figure 4 As shown, a drive mating column 134 is fixed inside the filter tube constraint sliding cylinder 132. The drive mating column 134 has a drive mating threaded hole 1340 that passes through the axis of the filter tube constraint sliding cylinder 132. A constraint drive threaded rod 135 is threadedly connected inside the drive mating threaded hole 1340. A constraint drive receiving shell 136 is fixed at the outer end of the filter tube constraint support cylinder 131. One end of the constraint drive threaded rod 135 extends into the constraint drive receiving shell 136. A constraint drive motor 137 for driving the constraint drive threaded rod 135 to rotate is fixed inside the constraint drive receiving shell 136.

[0041] The constraint drive motor 137 is a commercially available servo motor of the prior art.

[0042] In practical application, each slurry input pipe 101 has an independent valve to control its opening and closing, each slurry discharge pipe 102 has an independent valve to control its opening and closing, and each clear liquid discharge pipe 12 has an independent valve to control its opening and closing.

[0043] During the filtration process, the slurry inlet pipe 101 is open, the clear liquid outlet pipe 12 is open, and the slurry residue outlet pipe 102 is closed.

[0044] Using existing technology, the slurry to be treated is fed into the slurry filter enclosure 10 through various slurry inlet pipes 101. The slurry to be treated passes through various slurry filter plates 110 from the outside to the inside and enters the filter module support pipe 11.

[0045] Each slurry filter plate 110 intercepts the slurry residue in the slurry to be treated outside the filter module support tube 11. After filtration, the slurry forms clear liquid that flows inside the filter module support tube 11. Finally, the clear liquid is discharged through each clear liquid outflow pipe 12.

[0046] When the slurry residue inside the closed shell 10 of the slurry filter accumulates to a certain extent, the slag discharge process begins. At this time, the slurry inlet pipe 101 is in the open state, the clear liquid outlet pipe 12 is in the closed state, and the slurry residue outlet pipe 102 is in the open state.

[0047] Using existing technology, clean water is introduced into the slurry filter enclosure 10 through each slurry inlet pipe 101 using a delivery pump. The clean water flushes the inside of the slurry filter enclosure 10. After cleaning, the clean water mixed with slurry residue is discharged from each slurry residue outlet pipe 102.

[0048] When the filter module support tube 11 needs to be repaired or replaced, the output shaft of the constraint drive motor 137 drives the constraint drive threaded rod 135 to rotate. Under the threaded transmission, the constraint drive threaded rod 135 drives the drive mating column 134 together with the filter tube constraint sliding cylinder 132 and the end constraint cylinder shell 133 to move along the axis of the filter tube constraint support cylinder 131, and causes the end constraint cylinder shell 133 to move away from the filter module support tube 11, so that the end constraint cylinder shell 133 is disengaged from the end of the filter module support tube 11. Then, the other end of the entire filter module support tube 11 can be pulled out from the end sealed constraint tube 120 to remove the filter module support tube 11.

[0049] Conversely, during the installation of the filter module support tube 11, one end of the filter module support tube 11 is first inserted into the end sealing constraint tube 120. Then, the output shaft of the constraint drive motor 137 drives the constraint drive threaded rod 135 to rotate. Under the threaded transmission, the constraint drive threaded rod 135 drives the drive mating column 134, together with the filter tube constraint sliding cylinder 132 and the end constraint cylinder shell 133, to move along the axis of the filter tube constraint support cylinder 131. The end constraint cylinder shell 133 moves towards the filter module support tube 11, so that the end constraint cylinder shell 133 is sealed and fitted onto the end of the filter module support tube 11.
