Description

Technical Field

[0001] This application relates to the field of water collection tank drainage and stirring technology, and in particular to a water collection tank drainage device. Background Technology

[0002] In industrial production, especially in the field of waste paper pulping lines, the collection tank is an important part of the wastewater treatment system. Its main function is to collect and preliminarily treat the wastewater generated during the production process. The white water collection tank contains certain impurities such as sand, plastic and foam. During the pumping process of the white water collection tank, these impurities will block the inlet or outlet. Sand and gravel are easy to settle at the bottom of the tank and need to be cleaned regularly using equipment such as excavators; while light impurities such as plastic and foam float on the surface of the liquid and also need to be treated regularly.

[0003] To prevent impurities from clogging the water collection tank, it is necessary to clean it regularly using equipment such as excavators. It is also necessary to use a mechanical mixer to stir the liquid in the water collection tank to prevent the deposition of solid particles such as sand and gravel. Although the mechanical mixer can effectively prevent the deposition of impurities, it has a complex structure, high maintenance costs, and requires a large amount of additional electricity. Using an excavator for cleaning is labor-intensive and poses safety hazards. Utility Model Content

[0004] The purpose of this application is to overcome the above-mentioned technical problems and provide a drainage device for a water collection tank.

[0005] A drainage device for a water collection tank, comprising:

[0006] A stirring mechanism, comprising an air outlet pipe and an air source, wherein one end of the air outlet pipe is disposed in a water collection tank and the other end of the air outlet pipe is connected to the air source to stir the liquid in the water collection tank.

[0007] A drainage mechanism is located on one side of the water collection tank. The drainage mechanism includes a water pump. The inlet of the water pump is connected to the water collection tank, and the outlet of the water pump is connected to the drainage tank. The drainage mechanism discharges the agitated white water into the drainage tank.

[0008] By adopting the above solution, when white water is collected in the collection tank, the white water contains certain impurities such as sand, plastic, and foam. These impurities will accumulate at the bottom of the collection tank, causing blockage of the collection tank outlet. When the stirring mechanism is activated, the air inlet pipe is connected to the air source, and the gas is sprayed out from the air outlet, causing the water at the bottom of the collection tank to tumble, thereby stirring up the impurities at the bottom of the collection tank and preventing the impurities at the bottom of the tank from blocking the water outlet of the collection tank.

[0009] In one embodiment, the vent pipe includes a main pipe and several branch pipes, and the branch pipes are provided with vent holes.

[0010] By adopting the above scheme and setting multiple branch pipes, the air outlets on each branch pipe can face different directions, so that the gas blown out of the air outlet pipe can more comprehensively and evenly cover the bottom area of ​​the water collection tank, reducing the dead corners of stirring.

[0011] In one embodiment, the branch pipe includes a flow control pipe and an exhaust pipe, the air outlets are arrayed on the surface of the exhaust pipe along the extension direction of the exhaust pipe, and a ball valve is provided on the flow control pipe.

[0012] By adopting the above solution and setting multiple air outlets, the air outlet area of ​​the branch pipe is increased, which allows the branch pipe to sweep across the bottom sediment of the water tank with a larger area, thereby improving the stirring effect of the stirring mechanism. The ball valve can control the gas flow rate according to user needs.

[0013] In one embodiment, the exhaust pipe is inclined relative to the bottom of the water collection tank.

[0014] By adopting the above solution, since the impurities at the bottom of the water collection tank have a certain thickness, by setting the air outlet pipe at an angle to the bottom surface of the water collection tank, the gas sprayed out by the air outlet pipe can fully contact the cross-section of the impurities at the bottom of the water collection tank, thereby agitating the impurities at the bottom of the water collection tank to a greater extent.

[0015] In one embodiment, the air source is an air compressor.

[0016] By adopting the above solution, a stable gas supply to the gas outlet pipe can be achieved.

[0017] In one embodiment, a level sensor is provided in the drainage pool, and the level sensor is located near the top of the drainage pool.

[0018] By adopting the above scheme, the liquid level sensor can sense the water level in the drainage tank, thereby controlling the start and stop of the water pump and preventing the liquid level in the drainage tank and collection tank from becoming too high.

[0019] In one embodiment, the side wall of the water collection tank is provided with an inlet pipe that communicates with the drainage tank, and the inlet pipe is close to the bottom of the water collection tank and communicates with the water pump.

[0020] By adopting the above scheme, the water collection tank and the drainage tank are connected by setting up an inlet pipe.

[0021] In one embodiment, the top of the water collection tank is provided with a support, and the stirring mechanism is supported on the support. The support is U-shaped and its two ends are respectively fixed to the two sides of the top of the water collection tank.

[0022] By adopting the above solution, the support bracket plays a supporting role for the mixing mechanism, enabling the mixing mechanism to mix directly in the center of the water collection tank, thus making the mixing more uniform.

[0023] In one embodiment, the support includes a support frame and a sliding frame. The support frame is perpendicular to the plane containing the top surface of the water collection tank. The sliding frame is supported on the support frame and is perpendicular to the support frame. The stirring mechanism is supported on the sliding frame and can slide along the extension direction of the sliding frame.

[0024] By adopting the above solution, since the water collection tank is large in volume, the stirring mechanism cannot stir every part of the bottom of the water collection tank. The stirring mechanism can slide along the sliding frame, thereby moving to various parts of the bottom of the water collection tank and avoiding the formation of stirring dead zones.

[0025] In one embodiment, the water collection tank drainage device further includes a drive mechanism, which includes a traction power source located on both sides of the support and a traction rope connected to the traction power source. The end of the traction rope away from the traction power source is connected to the stirring mechanism, and the traction rope is parallel to the extension direction of the sliding frame.

[0026] By adopting the above scheme, and by setting up a traction power source and a traction rope, the mixing mechanism can be driven to move along the extension direction of the sliding frame.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When the water collection tank contains white water, which contains impurities such as sand, plastic, and foam, these impurities will accumulate at the bottom of the water collection tank, causing blockage of the outlet. Activating the stirring mechanism connects the air inlet pipe to the air source, and the gas is ejected from the air outlet, causing the water at the bottom of the water collection tank to tumble, thereby stirring up the impurities at the bottom of the water collection tank and preventing them from blocking the outlet of the water collection tank.

[0029] 2. By setting multiple branch pipes and simultaneously tilting the drain pipes relative to the bottom of the collection tank, the air outlets on each branch pipe can face different directions. This allows the gas blown out by the air outlets to more comprehensively and evenly cover the bottom area of ​​the collection tank, reducing dead zones in the stirring. Since the impurities at the bottom of the collection tank have a certain thickness, by setting multiple air outlets and tilting the air outlets to the bottom of the collection tank, the gas sprayed out by the air outlets can fully contact the cross-section of the impurities at the bottom of the collection tank, thereby agitating the impurities at the bottom of the collection tank to a greater extent.

[0030] 3. Due to the large volume of the water collection tank, the stirring mechanism cannot stir every part of the bottom of the water collection tank. The stirring mechanism can slide along the sliding frame, so that it can move to various parts of the bottom of the water collection tank and avoid the formation of dead spots in the stirring.

[0035] Therefore, it is necessary to provide a water collection tank drainage device that has low energy consumption and can agitate the sediment at the bottom of the water collection tank 3.

[0036] Please see Figure 1 , Figure 1 The first embodiment of this application provides a structural schematic diagram of a water collection tank drainage device, which includes a stirring mechanism 1 and a drainage mechanism 2.

[0037] The stirring mechanism 1 includes an air outlet pipe 11 and an air source 12. One end of the air outlet pipe 11 is located in the water collection tank 3, and the other end is connected to the air source 12. The drainage mechanism 2 includes a water pump 21. The inlet of the water pump 21 is connected to the water collection tank 3, and the outlet is connected to the drainage tank 4. The air source 12 is a gas generating device such as an air compressor and an air storage tank. In this application, the air source 12 is an air compressor. The compressed air generated by the air compressor is delivered to the branch pipe 112 through the main pipe 111, and then ejected from the air outlet 1123 on the branch pipe 112. The working pressure of the air compressor can be adjusted according to actual needs, usually between 0.5 and 0.8 MPa, to meet the stirring requirements under different working conditions. This device effectively prevents impurities from settling by using compressed air to drive the liquid flow in the tank, while achieving efficient wastewater discharge.

[0038] Please refer to the following: Figure 2-3 , Figure 2 for Figure 1The enlarged view of area A shows that the air outlet pipe 11 in the stirring mechanism 1 includes a main pipe 111 and several branch pipes 112. The main pipe 111 can be made of stainless steel, which has good corrosion resistance and strength. The branch pipes 112 can be divided into two stainless steel pipes, each with an air outlet 1123. The diameter of the air outlet 1123 can be set to 2 mm and evenly distributed along the branch pipes 112 to ensure that the compressed air can fully agitate the liquid at the bottom of the pool when it is ejected from the holes. The branch pipes 112 can be further divided into a flow control pipe 1121 and an exhaust pipe 1122. The flow control pipe 1121 is equipped with a ball valve 1124 for regulating the flow rate of compressed air. The ball valve 1124 can be made of stainless steel, which has good sealing performance and long service life. Since the impurities at the bottom of the water collection tank 3 have a certain thickness, the air outlet pipe 11 is set at an angle relative to the bottom surface of the water collection tank 3. The gas sprayed out by the air outlet pipe 11 can fully contact the cross surface of the impurities at the bottom of the water collection tank 3, thereby agitating the impurities at the bottom of the water collection tank 3 to a greater extent.

[0039] In this application, multiple branch pipes 112 can be installed, with each branch pipe 112 distributed at one of the four corners or the center of the collection tank 3. This multi-point arrangement can more evenly agitate the liquid in the tank, further improving the stirring effect. The air outlets 1123 of the branch pipes 112 can be circular or elliptical, and the shape can be adjusted according to actual needs. For example, elliptical air outlets 1123 can change the direction of airflow within a certain range, thereby enhancing the stirring effect. In addition, the length of the branch pipes 112 can be customized according to the size of the collection tank 3 to ensure that the sprayed airflow can cover the entire bottom area of ​​the tank.

[0040] Branch pipe 112 can be further divided into control pipe 1121 and exhaust pipe 1122. Control pipe 1121 is equipped with ball valve 1124, allowing operators to adjust the compressed air flow rate according to the amount of impurities and actual needs. Ball valve 1124 can also be used for emergency shut-off of the air supply 12. For example, in case of system malfunction or maintenance, operators can quickly close ball valve 1124 to stop the compressed air supply, thus ensuring the safe operation of the system. Furthermore, ball valve 1124 is simple and convenient to operate, adaptable to various working conditions, and can be made of stainless steel, featuring good sealing performance and long service life.

[0041] The water pump 21 in the drainage mechanism 2 is a submersible pump 21, installed in the pump pit within the collection tank 3. The inlet of the submersible pump 21 is connected to the collection tank 3, and the outlet is connected to the drainage tank 4 via a pipe. The power of the submersible pump 21 can be selected according to the capacity of the collection tank 3 and the drainage volume requirements. The function of the drainage tank 4 is to collect the wastewater discharged from the collection tank 3 for centralized treatment and discharge. A liquid level sensor 41 is installed inside the drainage tank 4, located near the top of the drainage tank 4, to monitor the liquid level height within the drainage tank 4. When the liquid level reaches a preset value, the liquid level sensor 41 will send a signal to remind the operator to handle the situation promptly. The liquid level sensor 41 can be a float type or a capacitive type, featuring fast response speed and high measurement accuracy. The side wall of the collection tank 3 is equipped with an inlet pipe 31 connected to the drainage tank 4, located near the bottom of the collection tank 3 and connected to the water pump 21. The diameter of the inlet pipe 31 should be designed according to the flow requirements; for example, a steel pipe can be selected to ensure sufficient flow capacity.

[0042] The support frame 5 includes a support frame 51 and a sliding frame 52. The support frame 51 is perpendicular to the plane of the top surface of the water collection tank 3, and the sliding frame 52 is supported on the support frame 51 and perpendicular to the support frame 51, thus forming a U-shape. The stirring mechanism 1 is supported on the sliding frame 52 and can slide along the extension direction of the sliding frame 52. This design allows the stirring mechanism 1 to be adjusted in position as needed, thereby better covering different areas within the water collection tank 3. The support frame 5 also has drive mechanisms 6 on both sides. The drive mechanisms 6 include traction power sources 61 located on both sides of the support frame 5 and traction ropes 62 connected to the traction power sources 61. The end of the traction rope 62 facing away from the traction power source 61 is connected to the stirring mechanism 1, and the traction rope 62 is parallel to the extension direction of the sliding frame 52. The traction power source 61 can be an electric hoist or a pneumatic motor, which drives the stirring mechanism 1 to move along the sliding frame 52 via the traction rope 62, thereby achieving dynamic adjustment of the stirring range.

[0043] The working principle of this application is as follows: When white water is collected in the water collection tank 3, the white water contains certain impurities such as sand, plastic, and foam. These impurities will accumulate at the bottom of the water collection tank 3, causing the outlet of the water collection tank 3 to be blocked. The stirring mechanism 1 is started, the air inlet pipe is connected to the air source 12, and the gas is sprayed out from the air outlet 1123, which causes the water at the bottom of the water collection tank 3 to roll, thereby stirring up the impurities at the bottom of the water collection tank 3 and preventing the impurities at the bottom of the water collection tank 3 from blocking the outlet of the water collection tank 3. The operator can adjust the stirring position of the stirring mechanism 1 through the driving mechanism 6, so that the sediment at the bottom of the water collection tank 3 can be fully stirred.

[0044] 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.
