Description

Technical Field

[0001] The utility model relates to a quick-cut filter, belonging to the technical field of filters. Background Art

[0002] Filters are a crucial device in chemical production. Most filters are installed in pipelines and are primarily used to separate and remove solid impurities, suspended matter, colloids, and other substances from fluids (including liquids and gases) to ensure the purity and quality of the fluids during production, ensuring the smooth progress of subsequent chemical processes and the quality of chemical products. Filters are prone to clogging after prolonged use and require frequent replacement. During replacement, the production line must be shut down, and workers must then remove the bolts connecting the filter to the pipeline, remove the clogged filter, and reconnect the new filter to the pipeline. This entire replacement process is time-consuming, severely impacting normal production. Furthermore, residual toxic gases in the pipeline can leak during replacement, posing a significant safety hazard. Utility Model Content

[0003] In view of the above deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a quick-cut filter which can be quickly switched when the filter is clogged, thereby shortening the filter switching time, avoiding long shutdown of the production line, and eliminating safety hazards.

[0004] The quick-cut filter described in the utility model includes a base, a fixed valve body and a movable valve body are installed above the base, the movable valve body is driven by a valve body driving device and can move along the axial direction of the valve body, a valve plate is provided between the fixed valve body and the movable valve body, the valve plate is rotatably connected to the fixed valve body, the valve plate is driven to rotate by the valve plate driving device, and two groups of basket filters are detachably connected to the valve plate.

[0005] The technical solution of the utility model is to provide a quick-cut filter, in which two groups of basket filters are installed on the valve plate, one group is in normal operation and the other group is on standby; when the normally operating filter is blocked, the valve plate is rotated to quickly switch to the standby filter to continue working, and the replaced filter can be disassembled and replaced by the worker, thereby shortening the replacement time.

[0006] Preferably, the basket filter is barrel-shaped and fixed to the valve plate by bolts; a filter screen is provided on one side of the basket filter.

[0007] Preferably, the movable valve body is provided with a bellows compensator for compensating for the displacement of the movable valve body.

[0008] Preferably, sealing members are provided on both sides of the valve plate. When the valve body is pressed against the valve plate, the sealing members can effectively prevent the fluid in the pipeline from leaking out.

[0009] Preferably, a screw pair is connected to the top of the movable valve body, and the valve body drive device is connected to the screw pair through a connecting rod group; when the valve body drive device is actuated, the connecting rod group drives the screw pair to rotate, and then the screw pair pushes the movable valve body to move.

[0010] Preferably, teeth are provided at the bottom of the valve plate, and the teeth are engaged with gears in the valve plate driving device, and the rotation of the gears can drive the valve plate to rotate.

[0011] Preferably, a toxic gas alarm is installed on the fixed valve body to monitor the concentration of toxic gas.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The quick-cut filter described in the utility model has two sets of basket filters installed on the valve plate. When the filter working normally is blocked, the valve plate can be rotated to quickly switch to the spare filter to continue working. The replaced filter can then be disassembled and replaced by workers. The utility model realizes the rapid switching of filters, shortens the filter switching time, avoids the long-term shutdown of the production line affecting normal production, and at the same time monitors the concentration of toxic gases nearby through the toxic gas alarm. When the toxic gas dissipates, the workers can replace the filter to eliminate safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] like Figures 1 to 4As shown, this embodiment is implemented through the following technical solutions: it includes a base 5, a fixed valve body 11 and a movable valve body 10 are installed above the base 5, the movable valve body 10 is driven by a valve body driving device 3, and can move along the axial direction of the valve body, a valve plate 7 is provided between the fixed valve body 11 and the movable valve body 10, the valve plate 7 is rotatably connected to the fixed valve body 11, the valve plate 7 is driven to rotate by the valve plate driving device 6, and two groups of basket filters 2 are detachably connected to the valve plate 7.

[0020] In this embodiment, the basket filter 2 is barrel-shaped and is fixed to the valve plate 7 by bolts; a filter screen 13 is provided on one side of the basket filter 2. A bellows compensator 9 is provided on the movable valve body 10 to compensate for the displacement of the movable valve body 10. Seals 12 are provided on both sides of the valve plate 7. When the valve body is pressed against the valve plate, the seals 12 can effectively prevent the fluid in the pipeline from leaking out. A screw pair 8 is connected to the top of the movable valve body 10, and the valve body drive device 3 is connected to the screw pair 8 through a connecting rod group 1. When the valve body drive device 3 is activated, the connecting rod group 1 drives the screw pair 8 to rotate, and the screw pair 8 then pushes the movable valve body 10 to move. The bottom of the valve plate 7 is provided with teeth, which mesh with the gears in the valve plate drive device 6. The rotation of the gears can drive the valve plate 7 to rotate. A toxic gas alarm 4 is installed on the fixed valve body 11 to monitor the concentration of toxic gases.

[0021] The working process of this utility model is:

[0022] 1. When the basket filter in the working position is clogged, the valve body drive device 3 is activated to push the movable valve body 10 away from the valve plate 7;

[0023] 2. The valve plate drive device 6 is activated, driving the valve plate 7 to rotate, switching the clogged basket filter to the standby position, and switching the basket filter in the standby position to the working position;

[0024] 3. The valve body drive device 3 moves again to clamp the valve plate 7 and seal it;

[0025] 4. The concentration of toxic gas in the vicinity is monitored by the toxic gas alarm 4. When the toxic gas alarm 4 does not sound an alarm, it indicates that the surrounding environment is safe. At this time, workers can go to replace the clogged basket filter.
