[0004] At present, when spraying medicine in the sedimentation tank, except for professional super-large sedimentation tanks, conventional sedimentation tanks with ordinary conditions need manual or medicine spraying machines to spray the medicine separately to achieve the treatment of wastewater. Regardless of whether it is operated manually or with a medicine sprayer, it is necessary to manually control the power of the sprayer and the angle and direction of the spraying. Therefore, it is difficult to control it to spray to the center of the sedimentation tank and spread it evenly during spraying, resulting in uneven fusion of the medicine and the wastewater. In addition, when spraying manually, the medicine is likely to splash onto the surrounding workers, causing certain hidden dangers to health during long-term work. Summary of the invention

[0018] The present invention provides an automatic dosing device for an industrial wastewater treatment sedimentation tank. It has the following beneficial effects:

[0019] 1. The present invention provides a lifting and spraying mechanism to automatically lift the water jacket to different angles, and cooperates with the spraying range of the medicine sprayed through the water spray hole under different pressures to accurately and quickly control the final landing point of the medicine sprayed through the water spray hole in the sedimentation tank, and finally stabilize it at a water pump pressure value, so that the continuous medicine spraying at a stable position can be maintained after the water jacket is lifted, without manually adjusting the spraying angle of the water jacket, and the operating parameters are single, so that the operation is convenient and not prone to errors, and the medicine is controlled to rotate synchronously in the water jacket in cooperation with the rotation of the blades, so that after the medicine collides with the water jacket and is broken up, when the rotating medicine passes through the inside of the water spray hole, since the inner wall of the water spray hole is in a vertical shape, the rotating medicine will be impacted by the inner wall of the water spray hole again and dispersed into multiple water beams, so that it is sprayed outward more evenly, reducing the uneven mixing in the medicine.

[0020] 2. The present invention sets a lifting spraying mechanism. When spraying medicine through the water sleeve in a smaller sedimentation tank, since the water pump pressure is small and the flow rate does not need to be too fast, the lifting angle of the water sleeve is small at this time, so the height of throwing the medicine is also low. When the medicine is thrown in the smaller sedimentation tank, the lower throwing angle is used to reduce the splash of the medicine falling in the center of the sedimentation tank, thereby preventing a large amount of water and medicine in the sedimentation tank from being splashed to the staff and environmental items outside the sedimentation tank, reducing the impact and damage to the environment and personnel outside the sedimentation tank, and avoiding the problem of imbalance in the ratio of medicine and water in the sedimentation tank caused by a large amount of water being splashed due to the small sedimentation tank.

[0021] 3. The present invention provides a lifting spraying mechanism. When the sedimentation tank is large, the water-passing jacket is automatically lifted to a higher angle to achieve high-altitude concentrated sprinkling, thereby increasing the impact force of the medicine when it falls into the center of the sedimentation tank, so that it can be quickly dissolved into the surrounding water that needs to be precipitated, increasing the speed of the medicine integration, and the medicine will naturally disperse when it is thrown down from the high altitude, so that when it falls into the sedimentation tank, a part of the medicine will naturally disperse to the surroundings, achieving a uniform sprinkling effect.

[0022] 4. The present invention sets a lifting spraying mechanism. When the water is sprayed through the spray hole, the sliding sleeve is subjected to the elastic force of the spring to continuously slide back and forth in the annular groove, thereby continuously squeezing the medicine normally sprayed in the water sleeve, so that the water pressure of the medicine in the water sleeve changes continuously. When the sliding sleeve slides into the annular groove, more water in the water sleeve is squeezed to spray out through the spray hole, so that the flow rate becomes faster at this time. When the sliding sleeve slides away from the annular groove, the pressure in the water sleeve is released, so that the speed of the water sprayed through the spray hole becomes slower, so that as the sliding sleeve slides back and forth in and out, the speed of the water sprayed out of the spray hole changes continuously, so that the water sprayed through the spray hole is more diffused in the air, and the water is more evenly mixed after falling.

[0023] 5. The present invention sets an observation mechanism. As the water-passing sleeve is lifted, the water-passing sleeve will drive the rotating shaft to rotate synchronously. The specific lifting angle of the water-passing sleeve can be judged by observing the rotation angle of the scale on the rotating shaft corresponding to the different positions in the pointer rod. Therefore, the approximate diameter of the sedimentation tank can be calculated and judged through the angle and whether the spraying position is in the center of the sedimentation tank, which is convenient for the staff to make a quick preliminary judgment on different sedimentation tanks.

[0024] 6. The present invention sets an observation mechanism, and through the impact of the medicine on the interception, the mixture in the medicine that is agglomerated due to accumulation and precipitation is fully broken up. After being broken up, it will be sprayed out along with the reciprocating vibration of the water spray hole and the sliding sleeve, and the medicine with high flow rate can be fully broken up when maintained at a high flow rate. Even if there is resistance, the impact is small due to the high pressure and high flow rate of the water pump. When spraying medicine on a sedimentation tank with a smaller area, the rotation speed of the blade is slower, and the centrifugal force at this time cannot pull the elastic force, so the blade is kept contracted at a position close to the center of the cylinder, so as to achieve the goal of not extending at a low flow rate, so as to avoid resistance to the circulation of medicine under low flow rate spraying. For different scenes and situations, a relatively good solution can be achieved adaptively. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] Example 1: Please refer to Figure 1-4 , the present invention provides a technical solution: an automatic dosing device for an industrial wastewater treatment sedimentation tank, comprising a lifting and spraying mechanism 3;

[0044] The lifting and spraying mechanism 3 comprises:

[0045] The fixing seat 301 is a circular columnar structure. A water pump is arranged inside the fixing seat 301. A water inlet 302 is fixedly connected to one side of the fixing seat 301, and a water outlet 303 is fixedly connected to the other side of the fixing seat 301. The fixing seat 301 is used to use the internal water pump to extract medicine from the water inlet 302 and discharge it through the water outlet 303, so as to play the role of spraying medicine;

[0046] The water-passing sleeve 305 is a hollow circular cylindrical structure. One end of the water-passing sleeve 305 is fixedly connected to a telescopic hose 311. One end of the telescopic hose 311 is fixedly connected to one end of the water outlet 303. The water-passing sleeve 305 is used to spray the medicine.

[0047] When it is necessary to add medicine to the sedimentation tank, the fixing seat 301 is fixed to the table around the sedimentation tank by bolts, and then one end of the water inlet 302 is connected to the previously prepared medicine through a pipeline, and the water pump inside the fixing seat 301 is started to pump the medicine into the water inlet 302 and the fixing seat 301 through the water inlet 302 and the pipeline, and enter the water outlet 303, enter the water sleeve 305 through the telescopic hose 311 at one end of the water outlet 303, and finally spray out through the water spray hole 308, so as to realize the automatic addition of medicine to the sedimentation tank;

[0048] Example 2: Please refer to Figure 1-12 Based on the first embodiment, the present invention provides a technical solution: the water inlet 302 is connected to the inside of the water outlet 303 through the water pump inside the fixing seat 301, and the inside of the water outlet 303 is connected to the inside of the water jacket 305 through the telescopic hose 311.

[0049] An annular groove 306 is formed on the inner wall of the water-passing sleeve 305 , a sliding sleeve 307 is slidably connected to the inner wall of the annular groove 306 , and a water spray hole 308 is formed on one side of the sliding sleeve 307 .

[0050] The inner wall of the water-passing jacket 305 is rotatably connected with blades 310 via a bearing. There are six blades 310 , and a cylinder 309 is fixedly connected to one side of the six blades 310 that are close to each other.

[0051] A spring 314 is fixedly connected to one side of the sliding sleeve 307 , and one end of the spring 314 is fixedly connected to one side of the inner wall of the annular groove 306 . A magnetic block A312 is fixedly connected to one side of one blade 310 .

[0052] A magnet B313 is fixedly connected to the outer ring position of the inner wall of the sliding sleeve 307 away from the center. The magnet A312 and the magnet B313 are magnetic and the magnetism of the same poles repel each other.

[0053] A connecting pipe 315 is fixedly connected to the bottom of the water-passing sleeve 305, one end of which is fixedly connected to an elastic telescopic rod 316, the interior of the connecting pipe 315 is connected to the interior of the water-passing sleeve 305, the interior of the connecting pipe 315 is connected to the interior of the elastic telescopic rod 316, both ends of the elastic telescopic rod 316 are fixedly connected to rotating balls 317, the outer wall of one of the rotating balls 317 is rotatably connected to a rotating sleeve 318, and the outer wall of the rotating sleeve 318 is fixedly connected to the bottom of the water-passing sleeve 305.

[0054] The outer wall of the rotating ball 317 of the elastic telescopic rod 316 away from the rotating sleeve 318 is rotatably connected to the outer wall of the fixed seat 301, the outer wall of the water-passing sleeve 305 is hinged with a hinge block 320, one side of the hinge block 320 is fixedly connected to the outer wall of the fixed seat 301, the outer wall of the water-passing sleeve 305 is provided with a one-way valve hole 321, and the outer wall of the elastic telescopic rod 316 is provided with a fine air hole 319;

[0055] When the liquid medicine is connected for spraying, when the liquid medicine passes through the water-passing sleeve 305, it will collide with the blade 310 inside the water-passing sleeve 305, and drive the blade 310 to rotate. When the blade 310 rotates, the magnet block A312 and the magnet block B313 on the outer wall repel each other through the magnetism of the same poles, pushing the magnet block B313 and the sliding sleeve 307 fixed thereto to slide outward in the annular groove 306, and pulling the spring 314 to deform it. When the magnet block A312 rotates away from the magnet block B313, the magnet block B313 loses the magnetic repulsion, and the sliding sleeve 307 is pulled back by the elastic force of the spring 314.

[0056] When the sliding sleeve 307 is pushed out and pulled back, the air in the annular groove 306 is squeezed through the connecting pipe 315 and enters the elastic telescopic rod 316, and the air in the annular groove 306 is replenished into the annular groove 306 through the one-way valve hole 321. As the liquid medicine in the water-passing sleeve 305 is continuously pressurized and sprayed outward by the water pump, the sliding sleeve 307 is continuously pushed out in the annular groove 306 and then pulled back by the spring 314, and the air is continuously drawn into the annular groove 306 from the outside through the one-way valve hole 321, and then the air is pushed back and forth by the sliding sleeve 307 and squeezed into the elastic telescopic rod 316 through the connecting pipe 315, so that the elastic telescopic rod 316 is continuously stretched and lengthened.

[0057] The outer wall of the elastic telescopic rod 316 itself is also provided with fine air holes 319 with smaller diameters. Therefore, the speed at which air enters the elastic telescopic rod 316 each time is greater than the speed at which the air inside the elastic telescopic rod 316 is squeezed out when the elastic telescopic rod 316 is retracted by the internal spring during the period of time when no air enters. At this time, the air intake of the elastic telescopic rod 316 is greater than the air discharge. At this time, the elastic telescopic rod 316 will stretch and lengthen, so that under the hinge connection of the rotating balls 317 at both ends of the elastic telescopic rod 316, the water-passing sleeve 305 is pushed upward through the rotating sleeve 318, and the water-passing sleeve 305 is rotated and lifted through the hinge block 320. As the water pump is pressurized, the water-passing sleeve 305 is 5, the flow rate in the water jacket 305 becomes faster, and the water jacket 305 begins to rise continuously. As the water jacket 305 rises higher, the elastic force inside the elastic telescopic rod 316 becomes greater. As a result, during the period from when the sliding sleeve 307 is rebounded by the spring 314 to when the air is squeezed into the elastic telescopic rod 316 next time, the elastic telescopic rod 316 is pulled by the elastic force of the built-in spring, thereby squeezing out more air in the elastic telescopic rod 316. As a result, as the angle of the water jacket 305 continues to rise, it will eventually rise to a fixed position and cannot continue to rise. The air inlet and outlet volumes in the elastic telescopic rod 316 reach a balance. When the water jacket 305 needs to continue to rise, the spraying volume of the water pump needs to be increased.

[0058] The one-way valve hole 321 is a one-way air inlet and outlet valve. The one-way valve hole 321 can only allow external air to enter the annular groove 306. The air in the annular groove 306 will not be squeezed and discharged through the one-way valve hole 321, thereby realizing one-way air circulation. In addition, the one-way valve hole 321 has a large diameter and the caliber does not affect the air circulation. The small diameter of the fine air hole 319 will cause a certain resistance to the air inlet and outlet of the elastic telescopic rod 316.

[0059] Therefore, when spraying medicine through the water-passing sleeve 305 in the sedimentation tank, if you want to spray the center of the sedimentation tank to make the medicine spread evenly, you only need to control the pressure of the water pump in the fixed seat 301 to change the water flow rate, and you can freely control the lifting angle of the water-passing sleeve 305, so as to automatically lift the water-passing sleeve 305 to different angles, and cooperate with the spraying range of the medicine sprayed through the water-spraying hole 308 under different pressures to accurately and quickly control the final landing point of the medicine sprayed through the water-spraying hole 308 in the sedimentation tank, and finally stabilize it at a water pump pressure value, so as to ensure After the water-passing sleeve 305 is lifted, the medicine is sprayed continuously at a stable position. There is no need to manually adjust the spraying angle of the water-passing sleeve 305. The operating parameters are single, which makes the operation convenient and not prone to errors. In addition, the medicine is controlled to rotate synchronously in the water-passing sleeve 305 in coordination with the rotation of the blade 310, so that after the medicine hits and breaks up the water-passing sleeve 305, when the rotating medicine passes through the inside of the water spray hole 308, the rotating medicine will be impacted by the inner wall of the water spray hole 308 again because the inner wall of the water spray hole 308 is in a vertical shape, and dispersed into multiple water beams, so as to be sprayed outward more evenly, reducing the unevenness of mixing in the medicine.

[0060] Moreover, when the fixing seat 301 is mounted on the side of sedimentation tanks of different sizes, the corresponding water pump pressure can be adjusted by the corresponding sedimentation tank, so that the angle after the water sleeve 305 is automatically lifted can spray the medicine to the center of the sedimentation tank. When the medicine is sprayed through the water sleeve 305 in a smaller sedimentation tank, since the water pump pressure is small and the flow rate does not need to be too fast, the angle of the water sleeve 305 lifting is small at this time, so the height of the medicine is also low. When the medicine is sprayed in the smaller sedimentation tank, the lower throwing angle is used to reduce the medicine splash caused by the medicine falling in the center of the sedimentation tank, so as to avoid a large amount of water and medicine in the sedimentation tank from being splashed to the staff and environmental items outside the sedimentation tank, reduce the impact and damage to the environment and personnel outside the sedimentation tank, and avoid the problem of imbalance in the ratio of medicine and water in the sedimentation tank caused by a large amount of water being splashed due to the small sedimentation tank.

[0061] In the case of a large sedimentation tank, the water jacket 305 is automatically raised to a higher angle to achieve high-altitude concentrated throwing, increase the impact force of the medicine when it falls into the center of the sedimentation tank, so that it can quickly dissolve into the surrounding water that needs to be precipitated, increase the speed of the medicine into the water, and when the medicine is thrown down from the high altitude, it will naturally disperse, so that when it falls into the sedimentation tank, it will naturally disperse a part of the medicine to the surrounding, so as to achieve a uniform throwing effect;

[0062] When the water is sprayed out through the spray hole 308, the sliding sleeve 307 is subjected to the elastic force of the spring 314 to continuously slide back and forth in the annular groove 306, thereby continuously squeezing the medicine normally sprayed in the water sleeve 305, so that the water pressure of the medicine in the water sleeve 305 is continuously changed. When the sliding sleeve 307 slides into the annular groove 306, it squeezes more water in the water sleeve 305 to spray out through the spray hole 308, so that the flow rate is faster at this time. When the sliding sleeve 307 slides away from the annular groove 306, the pressure in the water sleeve 305 is released, so that the speed of the water sprayed out of the spray hole 308 is slowed down. As the sliding sleeve 307 slides back and forth in and out, the speed of the water sprayed out of the spray hole 308 is continuously changed, so that the water sprayed through the spray hole 308 is more diffused in the air, and the water is more evenly mixed after falling.

[0063] Example 3: Please refer to Figure 1-17 , on the basis of the first embodiment and the second embodiment, the present invention provides a technical solution: an observation mechanism 4 is arranged outside the water-passing jacket 305, and the observation mechanism 4 includes a connecting plate 401, and the top of the water-passing jacket 305 is fixedly connected with the connecting plate 401, and the top of the connecting plate 401 contacts the limiting plate 402, and one end of the limiting plate 402 is fixedly connected with the outer wall of the fixing seat 301, and the limiting plate 402 is used to resist the connecting plate 401 to prevent the water-passing jacket 305 from excessive rotation, and the outer wall of the water-passing jacket 305 is fixedly connected with a rotating shaft 403, and both sides of the water-passing jacket 305 are rotatably connected with the inner wall of the hinge block 320 through the rotating shaft 403, and the outer wall of the rotating shaft 403 is fixedly connected with a pointer rod 404, and the inner wall of the hinge block 320 is provided with a scale 405;

[0064] And as the water-passing sleeve 305 is lifted, the water-passing sleeve 305 will drive the rotating shaft 403 to rotate synchronously. The specific lifting angle of the water-passing sleeve 305 can be judged by observing the rotation angle of the scale 405 on the rotating shaft 403 corresponding to the different positions in the pointer rod 404. Thus, the approximate diameter of the sedimentation tank can be calculated and judged by the angle and whether the spraying position is in the center of the sedimentation tank, which can facilitate the staff to make a quick preliminary judgment on different sedimentation tanks.

[0065] When spraying a large sedimentation tank under high pressure, the rotation speed of blade 310 increases, so that 407 will be thrown out with the centrifugal force, pulling 408 to deform, and the two ends of 407 slide on 406 at the two ends, and the more centrifugal the position of the left and right 406 is, the farther the distance is. Therefore, when 407 is thrown out along 406 at both ends, 407 stretches the side length and moves away from the center of the circle where blade 310 rotates. Therefore, when a large sedimentation tank is sprayed with a water pump at high pressure and quickly, 407 automatically stretches the side length and slides to the far end of blade 310, thereby intercepting the passing medicine, and through the impact of the medicine on 407 during the interception, the mixture in the medicine that has agglomerated due to accumulation and precipitation is fully After being dispersed, it will be sprayed out with the reciprocating vibration of the water spray hole 308 and the sliding sleeve 307. When the flow rate is kept high, the high-flow rate medicine can be fully dispersed. Even if it is subject to the resistance of 407, it is less affected by the high pressure and high flow rate of the water pump. When spraying medicine on a sedimentation tank with a smaller area, the rotation speed of the blade 310 is slower, and the centrifugal force on 407 cannot pull the elastic force of 408. Therefore, 407 remains retracted at a position close to the center of the cylinder 309, so that 407 does not extend at a low flow rate to avoid resistance to the circulation of medicine under low flow rate spraying. For different scenes and situations, adaptive implementation of a relatively good solution is achieved;

[0066] Finally, after stopping spraying, the built-in spring inside the elastic telescopic rod 316 will pull the elastic telescopic rod 316 back with the elastic force, and the air inside the elastic telescopic rod 316 will continue to be slowly discharged through the fine air holes 319, so that the elastic telescopic rod 316 gradually retracts to its original position, waiting for the next spraying and telescopic work.

[0067] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
