Description

Technical Field

[0001] This application relates to the technical field of wastewater treatment, and in particular to a filter media replacement device for a V-type filter bed. Background Technology

[0002] A V-type filter is a rapid filter that uses a constant water level for filtration. The inlet channels on both sides of the filter are V-shaped. An ultrasonic automatic water level control device inside the filter adjusts the outlet clear water valve, which automatically adjusts its opening degree according to the water level to maintain a constant water level. The V-type filter uses a single layer of sand filter media, typically with a particle size of 0.95–1.35 mm, a uniformity coefficient of 1.2–1.6, and a filter layer thickness of 1.0–1.5 μm.

[0003] The filter media inside the V-type filter needs to be cleaned and replaced in a specific location. When replacing the filter media, the old filter media must first be discharged from the inside of the filter using a suction pump. Then, the filter plates and filter heads need to be inspected and maintained. Finally, the new filter media is evenly laid inside the filter. Therefore, in order to discharge all the old filter media, the suction head of the suction pump needs to be moved constantly, which takes up a lot of time.

[0004] Regarding the aforementioned related technologies, the inventors have discovered the following drawbacks: the prior art lacks a shaking mechanism, the single suction range of the suction pump is small, the suction operation is slow, and it takes a long time. In order to solve the shortcomings of the prior art in terms of not being able to improve the efficiency of the suction operation, this application sets up components such as an inner positioning frame and an outer positioning frame, so that the positioning column can drive the hollow tube to swing back and forth inside the inner positioning frame through the support rod, and at the same time, the inner positioning frame can rotate back and forth inside the outer positioning frame, thereby expanding the suction range and improving the operation efficiency.

Two support rods are rotatably connected to the positioning block. A hollow tube is provided below the positioning column. An inner positioning frame is rotatably connected to the outer surface of the hollow tube. An outer positioning frame is rotatably connected to the outer surface of the inner positioning frame. Four support bars are fixedly connected to the outer surface of the outer positioning frame. The top end of each support bar is fixedly connected to the lower surface of the support box.

[0007] Optionally, a bottom frame is fixedly connected to the upper surface of the filter body, a support frame is provided above the bottom frame, and several bottom wheels are rotatably installed at the bottom of the support frame.

[0008] Optionally, a gantry frame is fixedly connected to the upper surface of the base frame, and a second slider is slidably connected inside the gantry frame.

This utility model, by setting up components such as a positioning rod and a positioning block, and through the cooperation between the positioning rod and the positioning block, allows the positioning rod to rotate and drive the positioning block to slide, thereby causing the positioning block to drive the hollow tube to rotate inside the inner positioning frame via the support rod.

[0018] The following is in conjunction with the appendix Figure 1-7 The figure provides a further detailed description of this application.

[0019] This application discloses a filter media replacement device for a V-type filter bed. For example... Figure 1 , 3 As shown in Figures 6 and 7, a filter media replacement device for a V-type filter includes a filter body 1. A support box 2 is disposed above the filter body 1.

Two support rods 6 are rotatably connected to the positioning block 5. A hollow tube 7 is disposed below the positioning column 4. The top end of the hollow tube 7 is rotatably connected to the bottom end of the support rods 6. A suction pump 3 is fixedly installed on the upper surface of the support box 2. The output end of the suction pump 3 is connected to the inside of the hollow tube 7 through a hose.

The positioning rod 17 is rotated by the rotating wheel, and the positioning rod 17 drives the positioning block 5 to slide. The positioning block 5 drives the hollow tube 7 to rotate inside the inner positioning frame 8 through the support rod 6, so that the swing amplitude of the hollow tube 7 changes.

[0022] Please see Figure 1 , 2 A bottom frame 14 is fixedly connected to the upper surface of the filter body 1. A support frame 11 is provided above the bottom frame 14.

Several bottom wheels 22 are rotatably installed at the bottom of the support frame 11.

[0023] Please see Figure 1 , 3 6. Each bottom wheel 22 is in contact with the upper surface of the bottom frame 14, thereby supporting the support frame 11. The upper surface of the bottom frame 14 slides in contact with the bottom end of the support frame 11. The robotic arm 13 can extend itself to drive the support box 2 and hollow tube 7 and other components to achieve lifting and lowering, which is a conventional technology. The first slider 12 can drive the robotic arm 13 to move, thereby adjusting the lateral position of the hollow tube 7 and other components.

[0024] Please see Figure 1 , 3 6. A first motor is fixedly installed on the outer surface of the support frame 11. A first drive rod 20 is fixedly connected to the output end of the first motor.

[0027] The implementation principle of a filter media replacement device for a V-type filter bed according to an embodiment of this application is as follows: When extracting old filter media, the mechanical arm 13 drives the support box 2 and other components to descend, so that the bottom end of the hollow tube 7 is close to the filter media inside the filter bed body 1. The suction pump 3 is started, and the suction pump 3 extracts the filter media through the hose and the hollow tube 7 and transports it to the outside of the filter bed body 1. The first motor is started, and the output end of the first motor drives the first drive rod 20 to rotate. The first drive rod 20 drives the first slider 12 to slide. The first slider 12 moves the robotic arm 13 and support box 2, thereby adjusting the lateral position of the suction pump 3 and hollow tube 7. The second motor is started, and its output drives the second drive rod 21 to rotate. The second drive rod 21 drives the second slider 16 to slide, and the second slider 16 moves the support frame 11, thereby adjusting the longitudinal position of the hollow tube 7. The positioning rod 17 is rotated, causing the positioning block 5 to slide. The positioning block 5, through the support rod 6, causes the hollow tube 7 to deflect inside the inner positioning frame 8. The drive motor is started, and its output... The output end drives the worm gear 19 to rotate, the worm gear 19 drives the worm wheel 18 to rotate, the worm wheel 18 drives the positioning column 4 to rotate, and the positioning column 4 drives the hollow tube 7 to reciprocate inside the inner positioning frame 8 through the positioning block 5 and the support rod 6. The amplitude of the reciprocating rotation is twice the deflection amplitude of the hollow tube 7. At the same time, the inner positioning frame 8 reciprocates inside the outer positioning frame 9, so that the bottom end of the hollow tube 7 makes a circular motion, thereby expanding the suction range and improving the suction efficiency. When laying the filter material, the input end of the suction pump 3 is inserted into the new filter material through a hose, and the output end of the suction pump is connected to the hollow tube 7 through a hose.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
