Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and specifically to a dosing device for river treatment with a uniform dosing function. Background Art

[0002] In the treatment of river pollution, the precise dosing of chemical agents (such as flocculants, disinfectants, algaecides, etc.) is a key link to improve the efficiency of sewage treatment. However, traditional dosing technologies have the following limitations in practical applications: 1. Insufficient uniformity of agent dosing Dependence on manual operation: The early manual dosing method requires estimating the dosing amount based on experience, which is prone to problems such as uneven distribution or over-dosing of agents, resulting in too high a concentration of agents in local water bodies and threatening the aquatic ecosystem.

[0003] Defects of fixed dosing devices: Most existing automated devices use single-point dosing or simple diversion structures, with a limited diffusion range of agents and difficulty in covering the cross-section of the river. Especially in wide rivers or areas with fast-flowing water, the agents are easily diluted or accumulated, affecting the treatment effect.

[0004] 2. Low mixing efficiency and high ecological risks Limitations of static mixing: Some devices promote the mixing of agents and river water through agitators or static mixers, but due to limitations in equipment volume and energy consumption, the mixing effect is poor, and the agents are easily concentrated in a high-concentration area near the dosing point, causing a toxic impact on microorganisms, fish, etc. in the short term.

[0005] Lack of pre-mixing mechanism: Traditional technologies mostly directly pump agents into the river without pre-dilution, resulting in the agents relying on natural water flow to slowly diffuse, prolonging the treatment cycle and possibly causing sediment pollution due to sedimentation. Summary of the Invention

[0006] The purpose of the present invention is to provide a dosing device for river treatment with a uniform dosing function to solve the problems proposed in the prior art.

[0007] To achieve the above purpose, the present invention provides the following technical solution: The dosing device includes a base, a medicine storage tank, a control cabinet, a water pump, and a dosing mechanism. The medicine storage tank is fixedly connected to the base, the water pump is fixedly connected to the base, the water pump is electrically connected to the control cabinet, the water inlet of the water pump is communicated with the medicine storage tank, and the dosing mechanism is communicated with the water outlet of the water pump. The dosing mechanism is used to uniformly dose the agent into the river for sewage treatment.

[0008] The base is used to provide an installation foundation for each mechanism. This application is used to treat river sewage. The dosing device can be installed in the river. The medicine storage tank is used to store the medicine. During the dosing operation, the control cabinet starts the water pump. The water pump pumps out the medicine in the medicine storage tank and pumps it into the dosing mechanism. The dosing mechanism can evenly distribute the medicine into the river.

[0009] Furthermore, the dosing mechanism includes a main pipe, branch pipes, and a mixing component. The main pipe is fixedly connected to the base. The water inlet of the main pipe is connected to the water outlet of the water pump. The water outlet of the main pipe is connected to the branch pipes. The outlets of the branch pipes are connected to the mixing component. A number of branch pipes are evenly arranged on the main pipe. The mixing component is submerged in the river and can mix the medicine evenly with the river water.

[0010] Through the pumping of the water pump, the medicine passes through the main pipe, branch pipes, and mixing component in sequence. Through a number of branch pipes evenly arranged on the main pipe, the medicine can be evenly distributed into the river with a large diffusion area. However, the medicine needs to be fully mixed with the water body to avoid the impact of short-term high-concentration medicine on the local ecology. And if directly put into the river, the medicine takes a long time to spread out. When dosing the medicine, a certain amount of water body is introduced through the mixing component to pre-mix with the medicine, thereby reducing the risk of instantaneous high concentration before the medicine spreads. And the mixed medicine solution is more likely to be evenly distributed with the water flow, which can avoid the precipitation or accumulation of the medicine at the dosing place and promote the diffusion of the medicine.

[0011] Furthermore, the mixing component includes a mixing pipe, a detection pipe, and a spray head. The mixing pipe, the detection pipe, and the spray head are arranged in sequence along the flow direction of the water. The water inlet of the mixing pipe is connected to the water outlet of the branch pipe. A vortex generator and a vortex street sensor are provided in the detection pipe. The vortex generator is located in the middle of the detection pipe. The vortex street sensor is arranged behind the vortex generator. The vortex street sensor is electrically connected to the control cabinet. An adjustment component is provided in the mixing pipe, and the adjustment component can automatically control the flow rate according to the data measured by the vortex street sensor.

[0012] The mixing pipe uses the power generated when the medicine flows to suck the water body in the river for pre-mixing. When the mixed medicine flows to the detection pipe, it will collide with the vortex generator, thereby forming alternating eddies behind the vortex generator. The vortex generator can guide the generation of controllable vortices to form a spiral fluid motion, enhancing the contact area between the medicine and the water body, thereby promoting the mixing of the medicine and the water body. In addition, the vortex street sensor arranged behind the vortex generator can detect the flow rate in the pipeline. After the medicine is mixed with the water body, the flow rate will have a certain fluctuation. Through the cooperation of the vortex street sensor and the adjustment component, the flow rate is automatically adjusted to ensure the even dosing of the medicine.

[0013] Further, the mixing tube is provided with a contraction section, a liquid guiding channel, a water outlet annular channel, a first outlet and a second outlet. The water inlet of the liquid guiding channel is communicated with the branch pipe, the water outlet of the liquid guiding channel is communicated with the adjusting assembly, the water inlet of the water outlet annular channel is communicated with the adjusting assembly, and the water outlet of the water outlet annular channel is communicated with the second outlet; A liquid distribution tray is arranged on the outer side of the contraction section. A liquid inlet pipe is arranged on the liquid distribution tray. The liquid inlet pipe penetrates through the mixing tube and is communicated with the outside. The water outlet of the liquid distribution tray is communicated with the first outlet.

[0014] When the medicament flows through the contraction section, the flow rate increases and the pressure decreases, so that the pressure at the contraction section is less than the pressure of the external water body. Under the action of the pressure difference, the external water body will flow into the liquid distribution tray through the liquid inlet pipe, and then flow into the contraction section through the first outlet, so as to realize the primary mixing of the medicament and the water body; in addition, a part of the medicament will flow into the water outlet annular channel through the liquid guiding channel and then return to the inside of the mixing tube through the second outlet, so that the medicament and the water body are mixed for the second time, that is, by arranging corresponding channels in the mixing tube, the multiple mixing of the medicament and the water body is realized, thereby improving the mixing degree of the medicament and the water body.

[0015] Further, the diameter of the liquid inlet pipe is smaller than the diameter of the contraction section.

[0016] If the diameter of the liquid inlet pipe is too large, sufficient negative pressure may not be generated. By controlling the ratio of the diameter of the liquid inlet pipe to the diameter of the contraction section within a suitable range, it can be ensured that the external water body is smoothly sucked into the contraction section.

[0017] Further, the first outlet and the second outlet are obliquely arranged on the mixing tube, and the inclination directions of the first outlet and the second outlet are opposite.

[0018] The first outlet and the second outlet with opposite inclination directions can form two spiral fluids with opposite rotation directions in the mixing tube, and these two fluids will collide with each other, thereby improving the mixing uniformity of the medicament and the water body.

[0019] Further, the adjusting assembly includes a rotating disk, an electromagnet and a supporting spring. The rotating disk is rotatably connected with the mixing tube. The rotating disk is provided with a flow-through hole, and the flow-through hole is communicated with the water inlet of the water outlet annular channel. The flow-through hole and the water inlet of the water outlet annular channel are arranged staggeredly. An arc-shaped groove is arranged on the mixing tube, and an arc-shaped slider is arranged on the rotating disk. The arc-shaped slider is slidably connected with the arc-shaped groove. The arc-shaped slider is made of ferromagnetic material. The electromagnet is fixedly connected with the inner wall of the arc-shaped groove. The electromagnet is electrically connected with the control cabinet. One end of the supporting spring is fixedly connected with the arc-shaped slider, and the other end of the supporting spring is fixedly connected with the inner wall of the arc-shaped groove.

[0020] Through the water inlet of the staggered flow-through holes and the water outlet annular channel, the flow-through cross-section formed by the two is relatively small and the flow rate is relatively small in the initial state; when the vortex street sensor detects a decrease in the flow rate, the electromagnet is activated. Under the action of the magnetic force, the ferromagnetic arc-shaped slider will shift towards the electromagnet side, the supporting spring is stretched under force, and the rotating disk deflects by a certain angle, increasing the overlapping area between the flow-through holes and the water inlet of the water outlet annular channel, thereby increasing the flow-through cross-section and increasing the flow rate; moreover, the smaller the flow rate detected by the vortex street sensor, the greater the current transmitted by the control cabinet to the electromagnet, the greater the deflection angle of the rotating disk, and the greater the overlapping area between the flow-through holes and the water inlet of the water outlet annular channel, increasing the water flow rate flowing out of the mixing pipe, that is, it realizes automatically controlling the water flow rate flowing out of the mixing pipe according to the flow rate detected by the vortex street sensor, enabling the medicament to be evenly dosed.

[0021] Furthermore, a clamping groove is provided on the base, and a medicine adding port is provided on the medicine storage tank.

[0022] The clamping groove on the base can facilitate the installation of the medicine dosing device at the required position, and the medicine adding port is used to add the medicament into the medicine storage tank.

[0023] Compared with the prior art, the beneficial effects of the present invention are: 1. The medicament is evenly dosed, avoiding local pollution, and a multi-stage diffusion design: the main pipe is combined with the uniformly distributed branch pipes to disperse the medicament to multiple dosing points, expanding the coverage range and significantly reducing the risk of excessive local medicament concentration.

[0024] 2. The mixing pipe automatically sucks in river water and the medicament for primary mixing through the negative pressure generated by the change in flow velocity in the contraction section, reducing the impact of the initial concentration of the medicament on the water body.

[0025] Reverse swirl enhanced mixing: The design with opposite inclination directions of the first outlet and the second outlet forms a reverse spiral flow, enhancing the contact area between the medicament and the river water through collision and disturbance, improving the mixing efficiency; in addition, the spiral structures of the vortex generator and the liquid guiding channel can reduce impurity accumulation, reduce the probability of blockage, and extend the service life of the equipment.

[0026] Intelligent flow regulation: Based on the real-time monitoring of flow fluctuations by the vortex street sensor, the adjustment component drives the rotating disk through the electromagnet to adjust the overlapping area between the flow-through holes and the water inlet of the water outlet annular channel, achieving dynamic flow balance and ensuring the stability of the medicament dosing amount.

[0027] 3. Pre-mixing reduces the instantaneous concentration: The medicament and the river water are pre-mixed into a uniform solution in the mixing pipe, avoiding the toxic effects of short-term high-concentration medicament on aquatic organisms during direct dosing; in addition, the mixed medicament solution is more likely to diffuse with the water flow, reducing the deposition of the medicament in the riverbed or sediment, reducing the long-term ecological risk, and realizing green water treatment.

Specific embodiments

[0030] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment: As Figures 1-8 shown, the present invention provides a technical solution for a river treatment dosing device with a uniform dosing function. The dosing device includes a base 1, a medicine storage tank 2, a control cabinet 3, a water pump 4, and a dosing mechanism 5. The medicine storage tank 2 is fixedly connected to the base 1, the water pump 4 is fixedly connected to the base 1, the water pump 4 is electrically connected to the control cabinet 3, the water inlet of the water pump 4 is communicated with the medicine storage tank 2, and the dosing mechanism 5 is communicated with the water outlet of the water pump 4. The dosing mechanism 5 is used to uniformly dose the medicine into the river to treat sewage.

[0032] The base 1 is used to provide an installation foundation for each mechanism. This application is used to treat river sewage. The dosing device can be installed in the river. The medicine storage tank 2 is used to store the medicine. During the dosing operation, the control cabinet 3 starts the water pump 4. The water pump 4 pumps out the medicine in the medicine storage tank 2 and pumps it into the dosing mechanism 5. The dosing mechanism 5 can evenly dose the medicine into the river.

[0033] The dosing mechanism 5 includes a main pipe 51, branch pipes 52 and a mixing component 53. The main pipe 51 is fixedly connected to the base 1. The water inlet of the main pipe 51 is communicated with the water outlet of the water pump 4. The water outlet of the main pipe 51 is communicated with the branch pipes 52. The outlets of the branch pipes 52 are communicated with the mixing component 53. A number of branch pipes 52 are evenly arranged on the main pipe 51. The mixing component 53 is submerged in the river, and the mixing component 53 can evenly mix the medicine with the river water.

[0034] Through the pumping of the water pump 4, the medicine sequentially passes through the main pipe 51, the branch pipes 52 and the mixing component 53. Through a number of branch pipes 52 evenly arranged on the main pipe 51, the medicine can be evenly dosed into the river with a large diffusion area; however, the medicine needs to be fully mixed with the water body to avoid the impact of short-term high-concentration medicine on the local ecology, and if directly dosed into the river, the medicine takes a long time to spread; when dosing the medicine, a certain amount of water body is introduced through the mixing component 53 to pre-mix with the medicine, so as to reduce the risk of instantaneous high concentration before the medicine spreads, and the mixed medicine solution is more likely to be evenly distributed with the water flow, which can avoid the precipitation or accumulation of the medicine at the dosing place and promote the diffusion of the medicine.

[0035] The mixing component 53 includes a mixing pipe 531, a detection pipe 532 and a spray head 533. The mixing pipe 531, the detection pipe 532 and the spray head 533 are arranged in sequence along the flow direction of the water flow. The water inlet of the mixing pipe 531 is communicated with the water outlet of the branch pipe 52. A vortex generator 534 and a vortex street sensor 535 are arranged in the detection pipe 532. The vortex generator 534 is located in the middle position of the detection pipe 532. The vortex street sensor 535 is arranged behind the vortex generator 534. The vortex street sensor 535 is electrically connected to the control cabinet 3. An adjustment component 54 is arranged in the mixing pipe 531, and the adjustment component 54 can automatically control the flow rate according to the data measured by the vortex street sensor 535.

[0036] The mixing tube 531 sucks in the water in the river channel by using the power when the medicament flows, and conducts pre-mixing. When the mixed medicament flows to the detection tube 532, it will collide with the vortex generator 534, thereby forming alternating eddies behind the vortex generator 534. The vortex generator 534 can guide the generation of controllable vortices, forming a spiral fluid motion, enhancing the contact area between the medicament and the water, and thus promoting the mixing of the medicament and the water. In addition, the vortex street sensor 535 arranged behind the vortex generator 534 can detect the magnitude of the flow rate in the pipeline. After the medicament is mixed with the water, the flow rate will have a certain fluctuation. By cooperating with the adjustment component 54 through the vortex street sensor 535, the flow rate is automatically adjusted, so as to ensure the uniform dosing of the medicament.

[0037] The mixing tube 531 is provided with a contraction section 5311, a liquid guiding flow channel 5312, a water outlet annular channel 5313, a first outlet 5314 and a second outlet 5315. The water inlet of the liquid guiding flow channel 5312 is communicated with the branch pipe 52, the water outlet of the liquid guiding flow channel 5312 is communicated with the adjustment component 54, the water inlet of the water outlet annular channel 5313 is communicated with the adjustment component 54, and the water outlet of the water outlet annular channel 5313 is communicated with the second outlet 5315. A liquid distribution disc 536 is arranged outside the contraction section 5311. The liquid distribution disc 536 is provided with a liquid inlet pipe 5361. The liquid inlet pipe 5361 penetrates through the mixing tube 531 and is communicated with the outside. The water outlet of the liquid distribution disc 536 is communicated with the first outlet 5314.

[0038] When the medicament flows through the contraction section 5311, the flow rate increases and the pressure decreases, so that the pressure at the contraction section 5311 is less than the pressure of the outside water body. Under the action of the pressure difference, the outside water body will flow into the liquid distribution disc 536 through the liquid inlet pipe 5361, and then flow into the contraction section 5311 through the first outlet 5314, thereby realizing the primary mixing of the medicament and the water. In addition, a part of the medicament will flow into the water outlet annular channel 5313 through the liquid guiding flow channel 5312, and then return to the inside of the mixing tube 531 through the second outlet 5315, so that the medicament and the water are mixed for the second time. That is, by setting corresponding flow channels in the mixing tube 531, the multiple mixing of the medicament and the water is realized, thereby improving the mixing degree of the medicament and the water.

[0039] The diameter of the liquid inlet pipe 5361 is smaller than the diameter of the contraction section 5311.

[0040] If the diameter of the liquid inlet pipe 5361 is too large, sufficient negative pressure may not be generated. By controlling the ratio of the diameter of the liquid inlet pipe 5361 to the diameter of the contraction section 5311 within a suitable range, it can be ensured that the outside water body is smoothly sucked into the contraction section 5311.

[0041] The first outlet 5314 and the second outlet 5315 are inclinedly arranged on the mixing tube 531, and the inclination directions of the first outlet 5314 and the second outlet 5315 are opposite.

[0042] The first outlet 5314 and the second outlet 5315 with opposite inclination directions can form two helical fluids with opposite rotation directions in the mixing tube 531, and these two fluids will collide with each other, thereby improving the mixing uniformity of the medicament and the water body.

[0043] The adjusting assembly 54 includes a rotating disk 541, an electromagnet 542 and a support spring 543. The rotating disk 541 is rotatably connected to the mixing tube 531. The rotating disk 541 is provided with a flow-through hole 5411, and the flow-through hole 5411 is communicated with the water inlet of the water outlet annular channel 5313. The flow-through hole 5411 and the water inlet of the water outlet annular channel 5313 are arranged staggeredly. The mixing tube 531 is provided with an arc-shaped groove 5316, and the rotating disk 541 is provided with an arc-shaped slider 5412. The arc-shaped slider 5412 is slidably connected to the arc-shaped groove 5316. The arc-shaped slider 5412 is made of ferromagnetic material. The electromagnet 542 is fixedly connected to the inner wall of the arc-shaped groove 5316. The electromagnet 542 is electrically connected to the control cabinet 3. One end of the support spring 543 is fixedly connected to the arc-shaped slider 5412, and the other end of the support spring 543 is fixedly connected to the inner wall of the arc-shaped groove 5316.

[0044] Through the staggeredly arranged flow-through hole 5411 and the water inlet of the water outlet annular channel 5313, the flow-through cross-section formed by the two is small and the flow rate is small in the initial state; when the vortex street sensor 535 detects a decrease in the flow rate, the electromagnet 542 is started. Under the action of the magnetic force, the ferromagnetic arc-shaped slider 5412 will deflect towards the electromagnet 542 side, the support spring 543 is stretched under force, and the rotating disk 541 deflects by a certain angle, so that the overlapping area of the flow-through hole 5411 and the water inlet of the water outlet annular channel 5313 increases, thereby increasing the flow-through cross-section and increasing the flow rate; and the smaller the flow rate detected by the vortex street sensor 535, the greater the current transmitted by the control cabinet 3 to the electromagnet 542, the greater the deflection angle of the rotating disk 541, and the greater the overlapping area of the flow-through hole 5411 and the water inlet of the water outlet annular channel 5313, so that the water flow rate flowing out of the mixing tube 531 increases, that is, it realizes automatically controlling the water flow rate flowing out of the mixing tube 531 according to the flow rate detected by the vortex street sensor 535, so that the medicament can be evenly dispensed.

[0045] The base 1 is provided with a card slot 11, and the medicine storage tank 2 is provided with a medicine adding port 21.

[0046] The card slot on the base 1 can facilitate the installation of the medicine dispensing device at the required position, and the medicine adding port 21 is used to add the medicament into the medicine storage tank 2.

[0047] Working principle of the present invention: The medicament is pumped by the water pump 4 and sequentially passes through the main pipe 51, the branch pipe 52 and the mixing assembly 53. Through a number of branch pipes 52 evenly arranged on the main pipe 51, the medicament can be evenly put into the river with a large diffusion area; when putting the medicament, a certain amount of water body is introduced through the mixing assembly 53 to pre-mix with the medicament. When the medicament flows through the contraction section 5311, the flow rate increases and the pressure decreases, so that the pressure at the contraction section 5311 is less than the pressure of the external water body. Under the action of the pressure difference, the external water body will flow into the liquid distribution tray 536 through the liquid inlet pipe 5361 and then flow into the contraction section 5311 through the first outlet 5314, thus realizing the primary mixing of the medicament and the water body; in addition, a part of the medicament will flow into the water outlet ring channel 5313 through the liquid guiding flow channel 5312 and then return to the inside of the mixing pipe 531 through the second outlet 5315, so that the medicament and the water body are secondarily mixed, that is, by setting corresponding flow channels in the mixing pipe 531, multiple mixing of the medicament and the water body is realized, thereby improving the mixing degree of the medicament and the water body; the vortex generator 534 and the vortex street sensor 535 in the detection pipe 532 monitor the flow rate of the mixed liquid in real time. If the flow rate is abnormal, the control cabinet 3 drives the electromagnet 542 to drive the rotating disk 541 to deflect, adjusting the overlapping area between the flow through hole 5411 and the water outlet of the water outlet ring channel 5313 to increase or decrease the flow rate and ensure the stable delivery of the medicament.
