Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater treatment filter device that is easy to replace. Background Technology

[0002] As an indispensable and important part of the wastewater treatment process, the performance of filtration devices directly affects the effectiveness and efficiency of wastewater treatment.

[0003] Traditional filter replacement requires stopping the wastewater treatment equipment, closing the valves to prevent further wastewater inflow, and emptying the filter. This interruption disrupts wastewater treatment and disrupts its continuity. Furthermore, filter replacement in some systems is extremely cumbersome, often requiring complex disassembly and installation procedures. This often necessitates using various tools to remove the filter's components, and careful adjustment of its position and angle to ensure correct installation. Some filters also suffer from poor structural design, leading to unstable operation and potential loosening or detachment of the filter, resulting in unfiltered wastewater being discharged directly. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a wastewater treatment filter device that is easy to replace, solving the problem of replacing the filter without interrupting water supply or using multiple tools to disassemble the components that fix the filter screen.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a replaceable wastewater treatment filter device, comprising: a tank; a treatment device, the outer wall of which is fixedly connected to the outer wall of the tank; a locking device, the outer wall of which is fixedly connected to the outer wall of the treatment device; the treatment device includes a limiting frame, the outer wall of which is symmetrically rotatably connected to a frame door, both ends of which are fixedly connected to a connecting rod, the end of which is away from the frame door being fixedly connected to a linkage block, the inner wall of which is slidably connected to a filter screen, and the outer wall of which is symmetrically fixedly connected to a locking device. When replacing the filter screen, it is not necessary to stop the water supply; the locking device can be opened and the old and new filter screens replaced by rotating the device.

[0008] Preferably, the outer wall of the limiting frame is fixedly connected to the outer wall of the tank, the outer wall of the linkage rod is rotatably connected to the inner wall of the limiting frame, and the end of the frame door near the limiting frame contacts the outer wall of the filter screen. Manually rotating the buckles at both ends of the outer wall of the limiting frame can release one end of the frame door, and manually pulling the frame door can drive the relevant components to move the locking device and release the other end of the frame door.

[0009] Preferably, the outer wall of the limiting frame is symmetrically rotatably connected to a rotating rod, the outer wall of the rotating rod is fixedly connected to a buckle, and the outer wall of the buckle is slidably connected to the outer wall of the frame door. The frame door can be locked by using the buckle.

[0010] Preferably, the locking device includes two limiting blocks. An L-shaped locking rod is rotatably connected to the inner wall of each limiting block. A compression spring is fixedly connected to one end of the L-shaped locking rod near the limiting block. The L-shaped locking rod and the limiting block are rotatably connected, and automatic reset and locking are achieved through the compression spring. When the frame door is closed, it can reliably lock the frame door to the outer wall of the limiting frame, ensuring the stability of the filter screen during the operation of the device and preventing the filter screen from loosening or falling off and affecting the sewage treatment effect.

[0011] Preferably, the outer wall of the limiting block is fixedly connected to the outer wall of the limiting block, the outer wall of the L-shaped locking rod is in contact with the outer wall of the frame door, and the end of the compression spring away from the L-shaped locking rod is fixedly connected to the outer wall of the limiting frame.

[0012] Preferably, the outer wall of the linkage block is slidably connected to the outer wall of the L-shaped locking rod, and the inclined surface of the linkage block is parallel to the inclined surface of the L-shaped locking rod. The rotation of the linkage rod drives the linkage block to rotate, and the inclined surface of the linkage block cooperates with the inclined surface of the L-shaped locking rod to realize the movement of the locking rod.

[0013] (III) Beneficial Effects

[0014] This invention provides a wastewater treatment filter that is easy to replace. It has the following advantages:

[0015] This utility model, through the combination of a processing device and a locking device, allows for filter replacement without interrupting the water supply. For example, the rotation of the linkage rod drives the linkage block to rotate, and the inclined surface of the linkage block engages with the inclined surface of the L-shaped locking rod to move the locking rod. Automatic reset and locking are achieved through a compression spring. When the frame door is closed, it reliably latches the frame door onto the outer wall of the limiting frame, ensuring the stability of the filter screen during operation and preventing it from loosening or falling off, thus affecting the wastewater treatment effect. A new filter screen is pushed into the limiting frame from the end with the clip, pushing out the used filter screen. This method eliminates the need for cumbersome disassembly and installation steps, saving time on filter screen replacement. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] Please see Figure 1-4 This utility model provides a technical solution: a filter device for sewage treatment that is easy to replace, comprising:

[0024] Tank 1; processing device 2, the outer wall of the processing device 2 is fixedly connected to the outer wall of the tank 1; locking device 3, the outer wall of the locking device 3 is fixedly connected to the outer wall of the processing device 2. Wastewater enters from the inlet pipe above the tank 1 and is filtered through the tank 1. The filtered water is discharged from the outlet pipe at the bottom of the tank 1. When the filter screen 26 in the processing device 2 needs to be replaced, it is not necessary to stop the water supply. The locking device 3 can be opened by rotating the processing device 2, the new filter screen 26 can be pushed into the processing device 2, and the used filter screen 26 can be pushed out.

[0025] The processing device 2 includes a limiting frame 20. A frame door 21 is symmetrically and rotatably connected to the outer wall of the limiting frame 20. A connecting rod 22 is fixedly connected to both ends of the frame door 21. A linkage block 23 is fixedly connected to the end of the connecting rod 22 away from the frame door 21. A filter screen 26 is slidably connected to the inner wall of the frame door 21. A locking device 3 is symmetrically and fixedly connected to the outer wall of the frame door 21. The outer wall of the limiting frame 20 is fixedly connected to the outer wall of the tank 1. The outer wall of the connecting rod 22 is rotatably connected to the inner wall of the limiting frame 20. The end of the frame door 21 near the limiting frame 20 contacts the outer wall of the filter screen 26. When the frame door 21 is manually pulled, it rotates on the inner wall of the limiting frame 20. During this process, because the connecting rod 22 is fixedly connected to both ends of the frame door 21, the linkage block 23, which is fixedly connected to the section of the connecting rod 22 away from the frame door 21, also rotates synchronously, causing the locking device 3 to move.

[0026] The outer wall of the limiting frame 20 is symmetrically connected to a rotating rod 24, and the outer wall of the rotating rod 24 is fixedly connected to a buckle 25. The outer wall of the buckle 25 is slidably connected to the outer wall of the frame door 21. The buckles 25 at both ends of the outer wall of the limiting frame 20 are rotated manually. During this process, because the outer wall of the rotating rod 24 is fixedly connected to the buckle 24, the rotating rod 24 rotates synchronously while the buckle 25 rotates, until one end of the frame door 21 is released.

[0027] The locking device 3 includes two limiting blocks 30. An L-shaped locking rod 31 is rotatably connected to the inner wall of each limiting block 30. A compression spring 32 is fixedly connected to one end of the L-shaped locking rod 31 near the limiting block 30. The outer wall of the limiting block 30 is fixedly connected to the outer wall of the limiting block 30. The outer wall of the L-shaped locking rod 31 contacts the outer wall of the frame door 21. The end of the compression spring 32 away from the L-shaped locking rod 31 is fixedly connected to the outer wall of the limiting frame 20. The outer wall of the linkage block 23 is slidably connected to the outer wall of the L-shaped locking rod 31, and the inclined surface of the linkage block 23 is parallel to the inclined surface of the L-shaped locking rod 31. While the moving block 23 rotates, because the inclined surface of the linkage block 23 is parallel to the inclined surface of the L-shaped locking rod 31, the linkage block 23 presses the L-shaped locking rod 31 against the limiting frame 20. During this process, because the inner wall of the limiting block 30 is rotatably connected to the L-shaped locking rod 31, the other end of the L-shaped locking rod 31 is raised, which can loosen the frame door 21 at the other end of the limiting frame 20. Then, the new filter screen 26 is pushed into the limiting frame 20 from the end with the buckle 25, and the used filter screen 26 is pushed out. Then, the frame door 21 is closed manually, and the buckle 25 is rotated to fasten to the outer wall of the frame door 21.

[0028] When in use, wastewater enters through the inlet pipe above the tank 1 and is filtered through the tank 1. The filtered water is discharged through the outlet pipe at the bottom of the tank 1. When the filter screen 26 in the treatment device 2 needs to be replaced, there is no need to stop the water. The locking device 3 can be opened by rotating the treatment device 2, the new filter screen 26 can be pushed into the treatment device 2, and the used filter screen 26 can be pushed out.

[0029] When the filter screen 26 needs to be replaced, first manually rotate the buckles 25 at both ends of the outer wall of the limit frame 20. During this process, because the outer wall of the rotating rod 24 is fixedly connected to the buckles 25, the rotating rod 24 will rotate synchronously while the buckles 25 are rotating, until one end of the frame door 21 is released.

[0030] Manually pull the frame door 21 to make it rotate on the inner wall of the limiting frame 20. During this process, because the two ends of the frame door 21 are fixedly connected to the connecting rod 22, while the connecting rod 22 rotates, the linkage block 23, which is fixedly connected to the connecting rod 22 away from the frame door 21, also rotates synchronously, driving the locking device 3 to move.

[0031] While the linkage block 23 is rotating, because the inclined surface of the linkage block 23 is parallel to the inclined surface of the L-shaped locking rod 31, the linkage block 23 presses the L-shaped locking rod 31 against the limiting frame 20. During this process, because the inner wall of the limiting block 30 is rotatably connected to the L-shaped locking rod 31, the other end of the L-shaped locking rod 31 is raised, which can release the frame door 21 at the other end of the limiting frame 20.

[0032] Then push the new filter 26 into the limiting frame 20 from the end with the buckle 25, and push out the used filter 26. Then manually close the frame door 21 and rotate the buckle 25 to fasten it to the outer wall of the frame door 21.

[0033] When the frame door 21 is closed, the linkage rod 22 drives the linkage block 23 to rotate, releasing the L-shaped locking rod 31. During this process, because the end of the L-shaped locking rod 31 near the limit block 30 is fixedly connected to the compression spring 32, the compression spring 32 can make the L-shaped locking rod 31 rotate on the inner wall of the limit block 30 and lock the frame door 21 of the limit frame 20 without the handle onto the outer wall of the limit frame 20.
