Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a constant liquid level control mechanism and a water treatment device comprising the same. Background Technique

[0002] With the improvement of environmental protection awareness, water treatment devices are more and more widely used in various fields. In many industrial production processes, including water treatment, the stable control of liquid level is a key factor to ensure production efficiency and product quality. Due to the changes in the feeding amount and discharging amount during the operation of the equipment, the liquid level often fluctuates. As an important part of the water treatment device, the constant liquid level control mechanism is of great significance for ensuring the stability and efficiency of the water treatment process.

[0003] After retrieval, the utility model patent with the Chinese patent number CN216092374U discloses a constant liquid level control device for a water plant filter tank, which relates to the technical field of constant liquid level control devices for filter tanks, and includes a filter tank body. The filter tank body is a hollow cuboid with an open top surface. A water level stabilizing mechanism is arranged inside the filter tank body. The water level stabilizing mechanism includes a first drain pipe, a water pump, a water intake tank, a second drain pipe and a water inlet hole. The first drain pipe is fixedly connected to the filter tank body. The second drain pipe is slidably connected to the first drain pipe. The water intake tank is fixedly connected to the second drain pipe. A water inlet hole is opened on the side wall of the water intake tank. The water pump is fixedly connected to the first drain pipe. Compared with the prior art, the utility model patent with the Chinese patent number CN216092374U realizes the adjustment of the height of the water intake tank, and further realizes the purpose of taking water at different liquid level heights inside the filter tank body. The water entering the water intake tank through the water inlet hole is discharged outside the first drain pipe through the second drain pipe and the first drain pipe by energizing the water pump.

[0004] However, in the actual use process of the above device, the liquid level inside the filter tank rises abnormally many times. The change of the liquid level inside the filter tank will cause the sliding column to act, and the sliding column will drive the two conductive columns to reciprocally collide and contact with the conductive rods of the fixed column. Frequent collision and contact will lead to an increase in the breakage rate of the device, and seriously affect the use of the device. Therefore, a constant liquid level control mechanism and a water treatment device comprising the same are proposed. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problem in the prior art that the liquid level inside the filter tank rises abnormally many times, resulting in the collision and contact between the conductive column and the conductive rod of the fixed column, leading to an increase in the breakage rate of the device, and seriously affecting the use of the device, and to propose a constant liquid level control mechanism and a water treatment device comprising the same.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A constant liquid level control mechanism, including a support plate, a drain pipe is arranged outside the support plate, a drainage pump for absorbing water is arranged outside the drain pipe, and a water intake tank is arranged outside the drain pipe;

[0008] A first control rod is movably connected to the outside of the water intake tank. A float ball for controlling the sliding of the first control rod is fixedly connected to one side of the first control rod close to the water surface. A second control rod is threadedly connected to the side of the first control rod away from the float ball. A sliding cylinder is fixedly connected to the side of the support plate away from the drainage pump. The sliding cylinder is slidably connected to the second control rod. A control air cavity for storing inert gas is formed between the second control rod and the sliding cylinder. A conductive column for controlling the start of the drainage pump is fixedly connected to the side of the second control rod away from the first control rod. A first buffer pad for buffering the second control rod is fixedly connected to the side of the support plate close to the sliding cylinder.

[0009] The above technical solution further includes:

[0010] A control frame is fixedly connected to the side of the support plate close to the drainage pump. A control switch is slidably connected inside the control frame. The control switch forms a closed circuit for starting the drainage pump by contacting the conductive column.

[0011] A through groove is opened on the outside of the water intake tank. A second buffer pad for buffering the float ball is fixedly connected inside the water intake tank.

[0012] The conductive column is slidably connected to the support plate.

[0013] A water treatment device including the constant liquid level control mechanism includes a water treatment pool. The support plate is fixedly connected to the water treatment pool. The water treatment pool is fixedly connected to the outside of the water treatment pool. The adjustment pool is fixedly connected to a sedimentation tank through a channel outside. An inlet is arranged outside the sedimentation tank.

[0014] The above technical solution further includes:

[0015] A filter grid is arranged outside the inlet.

[0016] An inlet and an outlet are arranged outside the water treatment pool.

[0017] The present utility model has the following beneficial effects:

[0018] 1. In the present utility model, the water in the water treatment device enters the inside of the water intake tank. The buoyancy of the water pushes the floating ball to drive the conductive column to slide upward through the first control rod and the second control rod. At the same time, the second control rod squeezes the inert gas inside the control air chamber formed by it and the sliding cylinder. After being squeezed, the density of the inert gas increases, preventing the upward trend of the second control rod. After the conductive column contacts the control switch, the control circuit for controlling the drainage pump is closed, and the drainage pump is energized to work to pump the water in the water treatment device.

[0019] 2. In the present utility model, when the conductive column is about to contact the control switch, the second control rod contacts the first buffer pad, which plays a buffering role in the movement of the second control rod. At the same time, the inert gas inside the control air chamber prevents the upward trend of the second control rod from increasing, and the moving speed of the second control rod decreases rapidly, so that the conductive column can normally contact the control switch without problems such as collision.

[0020] 3. In the present utility model, when it is necessary to adjust the height of the control liquid level, only the rotation between the first control rod and the second control rod needs to be controlled. Since the first control rod and the second control rod are threadedly connected, the rotation of the first control rod relative to the second control rod will drive the floating ball to change its height. By pulling the drain pipe, the first control rod slides down in the drain pipe of the drainage pump, and the height of the position where the second control rod is located at the water inlet is adjusted, thereby realizing the adjustment of the height of the control liquid level.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment 1

[0028] As Figures 1-4 shown, a constant liquid level control mechanism and a water treatment device including the same proposed by the present invention include a support plate 7. A drain pipe 10 is arranged outside the support plate 7. A drainage pump 11 for sucking water is arranged outside the drain pipe 10. A water intake tank 13 is arranged outside the drain pipe 10.

[0029] The water intake tank 13 is movably connected with a first control rod 16. The first control rod 16 is a vertical round rod and is in close contact with the water intake tank 13. A floating ball 15 for controlling the sliding of the first control rod 16 is fixedly connected to one side of the first control rod 16 close to the water surface. A second control rod 17 is threadedly connected to the side of the first control rod 16 away from the floating ball 15. The first control rod 16 changes the total length between the first control rod 16 and the second control rod 17 by rotation to realize the adjustment of the control liquid level. A sliding cylinder 21 is fixedly connected to the side of the support plate 7 away from the drainage pump 11. The sliding cylinder 21 is slidably connected with the second control rod 17. A control air cavity 22 for storing inert gas is formed between the second control rod 17 and the sliding cylinder 21. The inert gas is selected with good damping ratio, and the actual selection scheme is evaluated according to the installation cost. The sliding cylinder 21 is in close contact with the second control rod 17 to ensure that the control air cavity 22 is in a closed state. A conductive column 18 for controlling the start of the drainage pump 11 is fixedly connected to the side of the second control rod 17 away from the first control rod 16. A first buffer pad 20 for buffering the second control rod 17 is fixedly connected to the side of the support plate 7 close to the sliding cylinder 21.

[0030] A control frame 12 is fixedly connected to the side of the support plate 7 close to the drainage pump 11. The control frame 12 is used for fixing and protecting the control switch 19. The control frame 12 is box-shaped on the support plate 7. A control switch 19 is fixedly connected inside the control frame 12. The control switch 19 is two contact switches. The control frame 12 ensures that the control switch 19 is isolated from external moisture. The control switch 19 forms a closed loop for starting the drainage pump 11 by contacting the conductive column 18.

[0031] A through groove 14 is provided outside the water intake tank 13. A second buffer pad 23 that buffers the floating ball 15 is fixedly connected inside the water intake tank 13. The second buffer pad 23 is slidably connected to the first control rod 16, and the conductive column 18 is slidably connected to the support plate 7. Both the first buffer pad 20 and the second buffer pad 23 are made of rubber.

[0032] In this embodiment, during use, the water in the water treatment device will enter the inside of the water intake tank 13. The buoyancy of the water pushes the floating ball 15 to drive the first control rod 16 and the second control rod 17 to slide upward. During the upward sliding process of the second control rod 17, it will drive the conductive column 18 to slide upward. At the same time, the second control rod 17 squeezes the inert gas inside the control air chamber 22 formed by it and the sliding cylinder 21. After being squeezed, the density of the inert gas becomes larger, preventing the upward trend of the second control rod 17. After the water surface in the water treatment device reaches the upper limit, the conductive column 18 contacts the control switch 19, thereby closing the control circuit of the control drainage pump 11, and the drainage pump 11 is powered on to pump the water in the water treatment device. When the water level in the water treatment device is lower than the position of the floating ball 15, the conductive column 18 falls under the action of the floating ball 15, the first control rod 16, the second control rod 17, and the inert gas inside the control air chamber 22. The conductive column 18 is separated from the control switch 19, and thus the control circuit of the control drainage pump 11 is no longer closed, and the drainage pump 11 stops working.

[0033] When the conductive column 18 is about to contact the control switch 19, the second control rod 17 contacts the first buffer pad 20, buffering the movement of the second control rod 17. At the same time, the inert gas inside the control air chamber 22 prevents the upward trend of the second control rod 17 from becoming larger, and the moving speed of the second control rod 17 decreases rapidly, and the conductive column 18 contacts the control switch 19 normally without problems such as collision.

[0034] When it is necessary to adjust the height of the control liquid level, only the rotation between the first control rod 16 and the second control rod 17 needs to be controlled. Since the first control rod 16 and the second control rod 17 are threadedly connected, the rotation of the first control rod 16 relative to the second control rod 17 will drive the floating ball 15 to change in height. By pulling the drain pipe, the first control rod 16 slides down in the drain pipe 1 and the drainage pump 11, and the height of the position where the second control rod 17 is located is adjusted, thereby realizing the adjustment of the height of the control liquid level.

[0035] Embodiment Two

[0036] As Figures 1-4 shown, based on Embodiment One, it includes a water treatment pool 1. The support plate 7 is fixedly connected to the water treatment pool 1. The water treatment pool 1 is fixedly connected to the outside of the water treatment pool 1. The adjustment pool 2 is fixedly connected to the sedimentation pool 3 through a channel 6 on the outside, and a water inlet 5 is arranged outside the sedimentation pool 3.

[0037] A filter grid 4 is provided outside the water inlet 5, and a water inlet 9 and a discharge outlet 8 are provided outside the water treatment tank 1.

[0038] In this embodiment, during use and operation, the water to be treated enters the sedimentation tank 3 through the water inlet 5. In this process, it first passes through the filter grid 4, which is used to remove larger solid particles and impurities in the water to be treated. When the water to be treated passes through the filter grid 4, large particle substances will be intercepted on the grid, while the sewage passes through the grid and enters the sedimentation tank 3. Then, the water to be treated flows into the sand hopper of the sedimentation tank 3 along the tangent direction from the inlet. The water to be treated forms a swirling state, and the sand grains in the water to be treated are subjected to the action of centrifugal force and are thrown towards the inner wall of the sedimentation tank 3 and slide down along the inner wall to the sand hopper at the bottom of the sedimentation tank 3. The water after sedimentation of sand then enters the regulation tank 2 through the channel 6 to regulate the water quality and water volume. After being regulated, it enters the water treatment tank 1 from the water inlet 9, and after the water treatment inside the water treatment tank 1 is completed, it is discharged through the discharge outlet 8.

[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
