Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a self-quantitative dosing device and method based on sewage flow changes. Background Art

[0002] With the rapid development of industrialization and urbanization, sewage treatment has become an important link in pollutant treatment that cannot be ignored. Especially in the treatment of industrial sewage and urban domestic sewage, accurate and effective dosing management is crucial to the purification effect of sewage. During the treatment process, it is usually necessary to adjust the sewage treatment agent according to the sewage quality and its changes.

[0003] However, sewage flow often fluctuates with time and environmental changes. Traditional dosing devices usually use a fixed ratio or manual adjustment method, which cannot accurately adjust the dosage of the agent in real time according to the change of sewage flow. The fixed dosing method can easily lead to insufficient or excessive dosage of the agent; for example, the automatic dosing device for sewage disinfection applied for by the Chinese patent application number: CN110255681 B uses the water flow to impact the impeller to achieve the operation of receiving and dosing the agent, and controls the conduction flow of the agent in the dosing tube through the speed regulating valve; although the automatic dosing effect can be achieved, the following technical problems still exist in actual use: 1. Although the impeller can automatically dosing according to the change of water flow, it can only achieve the automatic dosing effect, and cannot automatically adjust the dosage according to the current water flow speed. 2. The dosing tube is controlled separately by the speed regulating valve and there is no linkage structure between it and the impeller. It is impossible to dynamically adjust the output amount of the agent in the dosing tube according to the conduction speed of the water flow or the rotation speed of the impeller. 3. It is impossible to automatically detect the pollution concentration of sewage and increase the dosage of medicine according to the monitoring results, which may easily lead to technical problems such as insufficient dosage of medicine.

[0004] Therefore, it is difficult to adapt to the needs of sewage and wastewater treatment. In addition, with the urgent and strict requirements of sewage treatment, the dosing device needs to have a higher level of precision and automation to ensure the continuity, stability and efficiency of the sewage treatment process. Summary of the invention

[0005] In view of the above problems, a self-quantitative dosing device based on sewage flow changes is provided. By proposing a device that can not only automatically adjust the dosage of the agent according to the sewage flow but also dynamically compensate the dosage according to the water pollution concentration, the technical problem that the existing automatic dosing equipment cannot automatically adjust the dosage of the agent according to the sewage flow and the water pollution concentration is solved. The device can automatically control the dosing according to the sewage flow change and the water pollution concentration detection data in real time, thereby effectively improving the accuracy of dosing, reducing manual operations, and improving the automation level and treatment efficiency of sewage treatment.

[0008] Preferably, the dynamic adjustment module also includes a second spoiler and a third spoiler respectively hingedly arranged on both sides of the first spoiler and two counterweights respectively detachably arranged at the bottom of the second spoiler and the third spoiler; the two counterweights are used to counterweight the second spoiler and the third spoiler respectively, so that the second spoiler and the third spoiler are always perpendicular to the ground.

[0009] Preferably, a limiting vertical rod and a guide member coaxially sleeved outside the limiting vertical rod are also vertically arranged on the top of the second spoiler. The limiting vertical rod rod passes through the base frame and slidably cooperates with the base frame through the guide member. The guide member is used to guide the limiting vertical rod to slide horizontally along the long side direction of the base frame.

[0010] Preferably, the guide module includes a guide sleeve, a resistance reduction element and a first fixed frame; the guide sleeve is fixedly arranged on the base frame in a vertical state by the first fixed frame; the resistance reduction element is rotatably arranged in the guide sleeve and a plurality of groups are equidistantly arranged along the axis of the guide sleeve; the plurality of groups of resistance reduction elements are enclosed to form a conduction channel for conduction of the control module.

[0011] Preferably, the guide module is further provided with a return spring capable of elastically supporting the control module to return to the starting point; the return spring is coaxially fixedly arranged on the top of the guide sleeve.

[0012] Preferably, the control module also includes a control rod capable of longitudinally sliding in the guide module and a limit ring coaxially arranged outside the control rod; the limit ring is arranged close to the bottom of the control rod; the material control plate is detachably arranged on the top of the control rod in a vertical state.

[0013] Preferably, the discharge module includes a material storage barrel, a support frame and a material guide bin; the material storage barrel is fixedly arranged on the base frame in a vertical state by the support frame and is located above the guide module; the material guide bin is fixedly arranged at the discharge port of the material storage barrel; the material guide bin is a rectangular bin body with a hollow structure and an opening at the bottom, and the surface of the material guide bin is also penetrated by an oblong through hole connected to the discharge port of the material storage barrel; the material control plate is slidably inserted and arranged in the material guide bin and cooperates with the gap of the material guide bin, and when the material control plate is longitudinally away from the material guide bin, the opening of the discharge port of the material storage barrel becomes larger, and vice versa.

[0014] Preferably, the discharge module also includes a compensation barrel fixedly arranged on one side of the storage barrel and a material control valve arranged at the discharge port of the compensation barrel; the material control valve is electrically connected to the sewage monitoring module to receive the pollution concentration signal fed back by the sewage monitoring module, and automatically adjust the opening and closing of the material control valve and the size of the opening according to the pollution concentration signal.

[0015] Preferably, a dosing method of a self-dosing device based on sewage flow rate change is applied to a self-dosing device based on sewage flow rate change, comprising the following steps:

[0016] S1: First, install the self-quantitative dosing device at the water inlet area of ​​the sewage pool, and ensure that the height of the self-quantitative dosing device base frame is slightly higher than the highest water level of the sewage pool, so as to ensure that the self-quantitative dosing device can operate at different water levels; at the same time, the fixed end of the dynamic adjustment module is fixedly connected to the bottom of the sewage pool, and the dynamic adjustment module is kept inclined with respect to the water flow direction;

[0017] S2: When sewage flows into the sewage pool, the water flow impacts the dynamic adjustment module, causing its swing angle to automatically adjust with the change of water flow intensity; the greater the water flow, the greater the inclination angle of the dynamic adjustment module; conversely, the smaller the water flow, the smaller the inclination angle;

[0018] S3: Since the free end of the dynamic adjustment module is hinged to the control module, the control module is driven to slide up and down in the guide module as the inclination angle of the dynamic adjustment module changes; when the control module slides up and down in the guide module, the control module synchronously drives the material control plate to move, so that the material control plate can dynamically adjust the opening size of the discharge port of the discharge module according to the change of water flow;

[0019] S4: The control plate adjusts its position according to the sliding stroke of the control module to control the dosage. When the water flow is large, the sliding stroke of the control plate increases, so that the opening of the discharge port becomes larger, and the flow rate of the medicine increases accordingly. When the water flow decreases, the sliding stroke of the control plate decreases, so that the opening of the discharge port becomes smaller, and the flow rate of the medicine decreases accordingly.

[0020] S5: The pollution concentration of sewage is detected in real time through the sewage monitoring module, and the electrical signal is fed back to the control valve to dynamically open the control valve according to the water pollution concentration. The compensation barrel is used to add additional medicine into the sewage pool to ensure that the amount of sewage treatment agent can be changed at any time according to the water pollution concentration to avoid insufficient dosage of agents.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention can automatically adjust the dosage according to the real-time changes in sewage flow rate through the cooperation of the dynamic adjustment module, the control module and the discharge module. The impact of the water flow on the dynamic adjustment module causes the control module to automatically slide longitudinally, thereby adjusting the size of the discharge port of the discharge module according to the sewage flow rate to achieve accurate drug delivery. This dynamic adjustment avoids the problem of insufficient or excessive dosage caused by sewage flow fluctuations in the prior art.

[0023] 2. The present invention realizes how to automatically detect the pollution concentration of the current flowing sewage through the cooperation of the compensation barrel, the control valve and the sewage monitoring module, and automatically opens the discharge port of the compensation barrel according to the value of the current pollution concentration, thereby achieving the effect of additionally injecting chemicals into the sewage, thereby ensuring the final treatment effect of the sewage.

[0024] 3. Through the vertically designed second and third spoilers, the water flow can directly and effectively act on the spoilers, increasing the resistance and the reaction speed of the control module. This structural design not only simplifies the response stroke of the control module, but also greatly improves the accuracy and sensitivity of adjusting the delivery of sewage treatment drugs.

[0025] 4. The present invention can be adaptively adjusted according to the changes in different sewage flow rates and pollution concentrations, and is suitable for sewage treatment needs in different environments, ensuring the accuracy of the dosage and the stability of the treatment effect. Regardless of how the sewage flow rate fluctuates, the optimal dosage of the agent can be guaranteed, thereby improving the sewage treatment effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0044] See also Figures 1 to 10 As shown: A self-quantitative dosing device based on sewage flow change, used to achieve control of the dosing amount of the sewage pool, comprising: a base frame 1; a guide module 2, the guide module 2 is vertically fixedly arranged on the base frame 1; a discharge module 3, the discharge module 3 is fixedly arranged on the base frame 1 and located above the guide module 2; a control module 4, the control module 4 is longitudinally slidably arranged in the guide module 2; the control module 4 is provided with a control plate 41 capable of controlling the discharge amount of the discharge module 3, the control plate 41 is longitudinally slidably arranged at the discharge port of the discharge module 3; a dynamic adjustment module 5, the dynamic adjustment module 5 is arranged in an inclined state below the base frame 1; the dynamic adjustment module 5 is provided with a fixed end and a free end, and the free end of the dynamic adjustment module 5 is hinged to the lower end of the control module 4; the fixed end of the dynamic adjustment module 5 is fixedly connected to the bottom of the sewage pool; when the sewage impacts the dynamic adjustment module 5, the dynamic adjustment module 5 can be tilted toward the water flow direction with the fixed end as the center of the circle; the sewage monitoring module 6 is fixedly arranged on the base frame 1, and the sewage monitoring module 6 is provided with a collection head 61 that can extract sewage, and the collection head 61 is arranged vertically toward the bottom of the sewage pool.

[0045] When it is necessary to dynamically add medicine according to the change of sewage flow in the sewage pool, first install the base frame 1 at the water inlet of the sewage pool, and ensure that the base frame 1 is above the highest water level line of the sewage pool. At this time, the dynamic adjustment module 5 will be installed under the base frame 1, and the dynamic adjustment module 5 will be placed in the sewage, and the fixed end of the dynamic adjustment module 5 will be fixed to the bottom of the sewage pool to ensure that the dynamic adjustment module 5 can operate stably in the water flow. During installation, the dynamic adjustment module 5 will be slightly tilted toward the direction of water flow in the sewage pool. After completing the installation of the equipment, open the water inlet gate of the sewage pool and sewage begins to flow in.

[0046] When sewage flows into and impacts the dynamic adjustment module 5, the swing angle of the dynamic adjustment module 5 will change according to the strength of the water flow. If the sewage flow is large, the swing angle of the adjustment module increases; on the contrary, if the water flow decreases, the swing angle decreases. This swing angle change directly drives the control module 4 hinged to the free end of the dynamic adjustment module 5 to move, so that the control module 4 performs longitudinal reciprocating sliding in the guide module 2.

[0047] The longitudinal sliding of the control module 4 will control the discharge port of the discharge module 3 through the control plate 41. When the water flow is large, the inclination angle of the dynamic adjustment module 5 is larger, the downward stroke of the control module 4 will also increase accordingly, and the discharge port of the discharge module 3 will open wider, thereby increasing the dosage; when the water flow is small, the inclination angle is small, the downward stroke of the control module 4 is shortened, and the opening of the discharge port of the discharge module 3 is also reduced, thereby reducing the dosage. Through this principle, the dosing device can dynamically adjust the dosage according to the changes in the water flow in the sewage pool. The sewage monitoring module 6 is used to detect the sewage pollution concentration in real time. When the detected sewage concentration far exceeds the normal pollution index, it will additionally control the action of the discharge module 3 to add medicine into the sewage pool.

[0048] The swing angle change of the dynamic adjustment module 5 is directly linked to the water flow, thereby realizing automatic adjustment of the dosage of the medicine in the sewage pool. Compared with the traditional system that requires manual intervention or preset fixed dosage, the device can respond to the change of sewage flow in real time, avoid the situation of over-dosing or under-dosing, improve the accuracy and efficiency of dosing, ensure the stability and effect of sewage treatment, and also reduce the waste of medicine and save operating costs.

[0049] The sewage monitoring module 6 includes a sewage monitoring instrument 62 , a transmission hose 63 and a second fixing frame 64 ; the sewage monitoring instrument 62 is fixed on the base frame 1 through the second fixing frame 64 ; the collection head 61 is connected to the detection end of the sewage monitoring instrument 62 through the transmission hose 63 .

[0050] The sewage monitor 62 is a prior art and will not be described in detail here. Specifically, it is an automatic sampling online COD detector: it is used for automatic detection of chemical oxygen demand COD in sewage, is equipped with a suction pump, can realize automatic sampling and analysis of sewage, and display the concentration of organic pollutants in real time; but it is not limited to an automatic sampling online COD detector.

[0051] In the non-detection state, the collection head 61 is continuously immersed in the sewage pool in cooperation with the transmission hose 63. When real-time sampling and analysis of the current sewage pollution concentration is required, it is only necessary to connect an external power supply to drive the sewage monitor 62 to operate, and the suction pump in the sewage monitor 62 will operate. The sewage in the current sewage pool will be sucked into the sewage monitor 62 through the transmission hose 63 and the collection head 61, and the sewage will be analyzed, detected and recorded by the sewage monitor 62.

[0052] See also Fig.10 As shown: the dynamic adjustment module 5 includes a telescopic rod 51 that can swing in one direction, a first spoiler 52 detachably arranged in the middle of the telescopic rod 51, and a hinge seat 53 hingedly arranged at the bottom of the telescopic rod 51; the telescopic rod 51 is fixed to the bottom of the sewage pool through the hinge seat 53.

[0053] The top end of the telescopic rod 51 constitutes a free end, and the bottom end of the telescopic rod 51 constitutes a fixed end.

[0054] The telescopic rod 51 is composed of a rod and a sleeve rod with a sliding sleeve arranged outside the rod; the sleeve rod is placed on the top of the rod and is hinged to the lower end of the control module 4 through a hinged part arranged on the top; the sleeve rod is arranged above the highest water level.

[0055] Since the bottom end of the telescopic rod 51 is fixedly connected to the bottom of the sewage pool through the hinge seat 53, it can only swing in one direction along the water flow direction; when the water inlet gate is opened, the water flow hits the first baffle plate 52 and causes the first baffle plate 52 to tilt toward the water flow direction, and at this time, the top end is pulled, that is, the free end controls the control module 4 to move longitudinally downward in the guide module 2; thereby cooperating with the material control plate 41 to slide to different positions according to different traction strokes; thereby achieving the effect of exporting different amounts of medicine.

[0056] Since the bottom end of the telescopic rod 51 is fixedly connected to the bottom of the sewage pool through the hinge seat 53, it can only swing in one direction along the water flow direction, avoiding the phenomenon of shaking in multiple directions under the action of external force. When the water inlet gate is opened, the water flow quickly hits the first spoiler 52, forcing it to tilt in the direction of the water flow. As the first spoiler 52 tilts, the control module 4 at the free end is synchronously pulled and moves longitudinally downward in the guide module 2.

[0057] During the downward movement of the control module 4, the material control plate 41 moves synchronously to control the amount of medicine discharged from the material discharge module 3. The position of the material control plate 41 changes accordingly through the dynamic change of the water flow, thereby achieving the purpose of accurate medicine addition. This allows the system to flexibly respond to different water flow conditions during operation, automatically adjust the amount of medicine added, and ensure accurate and effective medicine delivery during the wastewater treatment process.

[0058] The force of the water flow impacting the first spoiler 52 directly drives the telescopic rod 51 to swing, and combined with the adjustment of the material control plate 41, automatic and accurate dosing amount control is achieved; and the effect of self-adjusting dosing can be achieved without the intervention of external power equipment.

[0059] See also Fig.10 As shown: the dynamic adjustment module 5 also includes a second spoiler 54 and a third spoiler 55 respectively hingedly arranged on both sides of the first spoiler 52, and two counterweights 56 respectively detachably arranged at the bottom of the second spoiler 54 and the third spoiler 55; the two counterweights 56 are used to counterweight the second spoiler 54 and the third spoiler 55 respectively, so that the second spoiler 54 and the third spoiler 55 are always perpendicular to the ground.

[0060] The second spoiler 54 and the third spoiler 55 are respectively hingedly arranged on both sides of the first spoiler 52 through bearing seats; the third spoiler 55 and the second spoiler 54 have the same structure.

[0061] Since the second spoiler 54 and the third spoiler 55 are both detachably provided with a counterweight 56 ​​at the bottom, the setting of the counterweight 56 ​​ensures that the second spoiler 54 and the third spoiler 55 can be stably in a vertical state, so as to further increase the flow blocking area and optimize the impact effect of the water flow on the second spoiler 54 and the third spoiler 55. By vertically arranging the second spoiler 54 and the third spoiler 55 respectively, the transmission efficiency of the water flow force can be effectively improved, so that the water flow acts more directly on the surface of the second spoiler 54 and the third spoiler 55, thereby prompting the control module 4 to move more quickly and sensitively. At the same time, since the water-facing area of ​​the second spoiler 54 and the third spoiler 55 in the vertical state is maximized, the blocking effect on the water flow is enhanced, and the longitudinal displacement of the control module 4 can be completed within a short stroke, and then the discharge port opening of the discharge module 3 is accurately adjusted according to the change of the water flow in the sewage pool, so as to realize the adaptive adjustment of the drug delivery amount.

[0062] Through the vertically designed second spoiler 54 and third spoiler 55, the water flow can directly and effectively act on the second spoiler 54 and the third spoiler 55, increasing the resistance and the reaction speed of the control module 4. The second spoiler 54 and the third spoiler 55 not only simplify the response stroke of the control module 4, but also greatly improve the accuracy and sensitivity of adjusting the delivery of sewage treatment drugs.

[0063] See also Fig.10As shown: a limiting vertical rod 541 and a guide member 542 coaxially sleeved outside the limiting vertical rod 541 are also vertically arranged on the top of the second spoiler 54. The rod portion of the limiting vertical rod 541 passes through the base frame 1 and is slidably matched with the base frame 1 through the guide member 542. The guide member 542 is used to guide the limiting vertical rod 541 to slide horizontally along the long side direction of the base frame 1.

[0064] The limiting vertical rod 541 vertically arranged on the top of the second spoiler 54 is used to further limit the second spoiler 54 so that it can only be arranged in a vertical state, so that the second spoiler 54 can contact the sewage with a maximum contact surface, so that the force of the sewage acting on the second spoiler 54 can be completely converted and acted on the control module 4, so that it moves longitudinally downward along the guiding direction of the guiding module 2; thereby adjusting the material control position of the material control plate 41;

[0065] The guide member 542 is a sliding block and has a through hole in the middle thereof for the limiting vertical rod 541 to pass through; the sliding block is slidably disposed in a sliding groove 11 that penetrates and is provided on the base frame 1 .

[0066] See also Figure 5 and Figure 8 As shown: the guide module 2 includes a guide sleeve 21, a resistance reducing element 22 and a first fixing frame 23; the guide sleeve 21 is fixedly arranged on the base frame 1 in a vertical state through the first fixing frame 23; the resistance reducing element 22 is rotatably arranged in the guide sleeve 21 and a plurality of groups are equidistantly arranged along the axis of the guide sleeve 21; the plurality of groups of resistance reducing elements 22 are enclosed to form a conduction channel for conduction of the control module 4.

[0067] The resistance reducing element 22 is preferably a roller, but is not limited to a roller;

[0068] The conduction channel formed by the multiple groups of resistance reduction elements 22 is used to provide guidance during the sliding process of the control module 4. Through the cooperation between the multiple groups of resistance reduction elements 22, the friction resistance of the control module 4 during the sliding process can be greatly reduced, and the control module 4 can slide smoothly and with low resistance in the guide sleeve 21. When the dynamic adjustment module 5 is impacted by the water flow and its free end is forced to move downward, the dynamic adjustment module 5 will synchronously drive the control module 4 to slide longitudinally in the guide module 2. In order to ensure the conduction efficiency and avoid the control module 4 being affected by the friction of the inner wall of the guide module 2 during the sliding process, multiple groups of resistance reduction elements 22 are provided, and the structural form of the multiple groups of resistance reduction elements 22 is preferably a roller or a low-friction slider, so as to enclose a conduction channel for the longitudinal sliding of the control module 4. When the control module 4 is driven by the dynamic adjustment module 5 to slide along the guide channel, it directly contacts the surface of the resistance reduction element 22, thereby reducing friction loss, ensuring that the longitudinal sliding operation is completed with minimum resistance, and improving the response speed and adjustment accuracy of the control module 4.

[0069] By arranging multiple groups of resistance reduction elements 22 in the guide module 2, the friction resistance of the control module 4 during the longitudinal sliding process can be effectively reduced, ensuring the rapid and smooth movement of the control module 4 and avoiding the response delay or reduced system efficiency caused by excessive friction.

[0070] See also Figure 5 As shown, the guide module 2 is further provided with a return spring 24 which can elastically support the control module 4 to return to the starting point; the return spring 24 is coaxially fixedly arranged on the top of the guide sleeve 21 .

[0071] When the sewage is continuously discharged, the dynamic adjustment module 5 starts to work under the continuous impact of the water flow, driving the control module 4 to move down longitudinally and cooperate with the material control plate 41, so as to gradually open the discharge port of the discharge module 3. In the process of the control module 4 moving down, the reset spring 24 will be compressed synchronously to be in a compressed state, and will remain compressed as the water flow continues to be discharged. When the sewage is discharged, the elastic force of the reset spring 24 will be automatically released and reset to the original state. At the same time, in the process of releasing the elastic force, the reset spring 24 pushes the control module 4 back from the downward position to the starting position, ensuring that the control module 4 returns to the initial setting point, so as to prepare for the next operation.

[0072] The automatic reset function is realized by combining the reset spring 24 with the control module 4. The reset spring 24 will automatically release its elastic force when the sewage stops being discharged, pushing the control module 4 to reset to the origin, ensuring that the equipment can quickly return to its initial state, providing continuity and reliability for the next sewage discharge and dosing operation.

[0073] See also Figure 5 and Figure 7 As shown: the control module 4 also includes a control rod 42 that can slide longitudinally in the guide module 2 and a limit ring 43 coaxially arranged outside the control rod 42; the limit ring 43 is arranged close to the bottom of the control rod 42; the material control plate 41 is detachably arranged on the top of the control rod 42 in a vertical state.

[0074] The material control plate 41 is specifically an arc-shaped vertical plate.

[0075] In the working state, the control rod 42 is coaxially slidably installed inside the guide module 2, and its bottom end is hingedly connected to the free end of the telescopic rod 51 through a hinged portion; a limit ring 43 is coaxially fixed to the outside of the control rod 42, and the limit ring 43 abuts against the top of the reset spring 24, thereby providing elastic support for the control rod 42. When the control rod 42 is subjected to external tension during operation, the limit ring 43 will compress the reset spring 24, so that the control rod 42 slides along the longitudinal direction of the guide module 2, thereby realizing the downward movement of the control rod 42. When the external tension disappears or is released, the elastic force of the reset spring 24 will prompt the control rod 42 to return to its original position, so that it automatically resets to the initial position, ensuring that the device can quickly return to the initial state for the next operation.

[0076] See also Figure 3 and Figure 4 As shown: the discharge module 3 includes a storage barrel 31, a support frame 32 and a material guide bin 33; the storage barrel 31 is fixedly arranged on the base frame 1 in a vertical state through the support frame 32 and is located above the guide module 2; the material guide bin 33 is fixedly arranged at the discharge port of the storage barrel 31; the material guide bin 33 is a rectangular bin body with a hollow structure and an opening at the bottom, and the surface of the material guide bin 33 is also penetrated by an oblong through hole connected to the discharge port of the storage barrel 31; the material control plate 41 is slidably inserted and arranged in the material guide bin 33 and is gap-matched with the material guide bin 33. When the material control plate 41 moves away from the material guide bin 33 longitudinally, the opening of the discharge port of the storage barrel 31 becomes larger, and vice versa.

[0077] When it is necessary to control the storage barrel 31 to have different outlet speeds and medicine outlet amounts according to different dosing requirements, it is only necessary to drive the control plate 41 to move so that the control plate 41 can slide and adjust in the guide bin 33. When no dosing is performed, the control plate 41 is fully inserted into the guide bin 33 and is close to the wall of the guide bin 33, thereby completely sealing the oblong through hole provided in the guide bin 33 to ensure that the medicine in the storage barrel 31 will not flow out. During the dosing operation, the control plate 41 is driven to be gradually pulled out of the guide bin 33. The longer the pull-out stroke of the control plate 41 is, the larger the exposed area of ​​the outlet of the storage barrel 31 is, so that the medicine in the storage barrel 31 can be discharged at a larger flow rate. According to the different pulling-out strokes of the material control plate 41, the opening size of the discharge port also changes accordingly, thereby realizing precise control over the medicine extraction speed and dosage; through the above principle, the material control plate 41 is linked with the dynamic adjustment module 5 and the guide module 2, and the pulling-out stroke of the material control plate 41 is adjusted through the changes in different sewage flow rates, thereby realizing different discharge effects when the material control plate 41 is displaced to different strokes.

[0078] See also Figure 3As shown: the discharge module 3 also includes a compensation barrel 34 fixedly arranged on one side of the storage barrel 31 and a material control valve 35 arranged at the discharge port of the compensation barrel 34; the material control valve 35 is electrically connected to the sewage monitoring module 6 to receive the pollution concentration signal fed back by the sewage monitoring module 6, and automatically adjust the opening and closing and the opening size of the material control valve 35 according to the pollution concentration signal.

[0079] The combined design of the compensation barrel 34 and the control valve 35 can provide more flexible dosing control during the sewage treatment process. The compensation barrel 34 is used to store additional reagents, and the release of the reagents is controlled by the control valve 35 arranged at its discharge port. The electrical signal connection between the control valve 35 and the sewage monitoring module 6 enables the control valve 35 to automatically adjust its switch state and opening size according to the real-time monitoring data of the pollutant concentration in the sewage. Through this design, the control valve 35 can adjust the discharge amount according to the different pollution concentrations, so as to achieve the effect of adding additional medicine when treating sewage with higher pollution concentrations.

[0080] A dosing method for a self-quantitative dosing device based on sewage flow change is applied to a self-quantitative dosing device based on sewage flow change, comprising the following steps:

[0081] S1: First, install the self-quantitative dosing device at the water inlet area of ​​the sewage pool, and ensure that the height of the self-quantitative dosing device base frame 1 is slightly higher than the highest water level of the sewage pool, so as to ensure that the self-quantitative dosing device can operate at different water levels; at the same time, the fixed end of the dynamic adjustment module 5 is fixedly connected to the bottom of the sewage pool, and the dynamic adjustment module 5 is kept inclined with respect to the water flow direction;

[0082] S2: When sewage flows into the sewage pool, the water flow impacts the dynamic adjustment module 5, causing its swing angle to automatically adjust with the change of water flow intensity; the greater the water flow, the greater the inclination angle of the dynamic adjustment module 5; conversely, the water flow decreases and the inclination angle decreases accordingly;

[0083] S3: Since the free end of the dynamic adjustment module 5 is hinged to the control module 4, the control module 4 is driven to slide up and down in the guide module 2 as the inclination angle of the dynamic adjustment module 5 changes; when the control module 4 slides up and down in the guide module 2, the control module 4 synchronously drives the material control plate 41 to move, so that the material control plate 41 can dynamically adjust the opening size of the discharge port of the discharge module 3 according to the change of the water flow;

[0084] S4: The control plate 41 adjusts its position according to the sliding stroke of the control module 4, thereby controlling the dosage of the medicine. When the water flow is large, the sliding stroke of the control plate 41 increases, so that the opening of the discharge port becomes larger, and the flow rate of the medicine increases accordingly. When the water flow decreases, the sliding stroke of the control plate 41 decreases, so that the opening of the discharge port becomes smaller, and the flow rate of the medicine decreases accordingly.

[0085] S5: The pollution concentration of the sewage is detected in real time through the sewage monitoring module 6, and fed back to the control valve 35 through the electrical signal, so as to dynamically open the control valve 35 according to the water pollution concentration, and additionally add medicine into the sewage pool through the compensation barrel 34 to ensure that the amount of sewage treatment agent can be changed at any time according to the water pollution concentration to avoid insufficient dosage of the agent.

[0086] The present invention can not only dynamically adjust the dosage according to the change of sewage flow, but also dynamically compensate the agent according to the sewage pollution degree.

[0087] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
