Description

Technical Field

[0001] The invention relates to the technical field of water treatment equipment, and in particular to a full-automatic pretreatment air-powered scale-inhibiting device. Background Art

[0002] Scale refers to solid deposits formed by the precipitation of dissolved calcium and magnesium ions in industrial water under specific conditions. It is widely present in industrial water treatment, boiler equipment, heat exchangers and piping systems. The formation of scale will significantly reduce the operating efficiency of industrial equipment, not only affecting heat transfer performance and increasing energy consumption, but also causing pipeline blockage, equipment corrosion and other problems. In severe cases, it may even cause equipment shutdown or damage, increasing production costs and maintenance difficulties. How to effectively prevent scale in industrial water pretreatment is a key technical problem that needs to be solved in the industry.

[0003] Traditional anti-scaling methods mainly include chemical anti-scaling, physical anti-scaling and electrochemical anti-scaling. Among them, anti-scaling agents are used in the pretreatment stage of industrial ultrapure water. Chemical anti-scaling agents are widely used because of their significant anti-scaling effect and simple operation. They react chemically with scale components such as calcium and magnesium ions in industrial water or form a protective film to effectively inhibit scaling. They are mainly concentrated before the reverse osmosis (RO) or nanofiltration (NF) membrane system to solve the scaling problem that may be caused by hardness ions in water (such as calcium, magnesium, sulfate, carbonate, etc.). The purpose of this application is to protect equipment and improve pretreatment efficiency.

[0004] However, traditional antiscaling technology still has significant limitations in actual industrial applications. For example, the way antiscalants are added is often difficult to evenly distribute in the target area and form effective coverage due to the uneven flow of liquids and the existence of local dead corners in industrial water systems. The antiscaling effect of antiscalants is highly dependent on their full contact with the target area. In circulating flow conditions, it is often difficult for antiscalants to be evenly distributed. Uneven distribution will directly lead to the inability to effectively solve local scaling problems, thereby reducing the overall system antiscaling efficiency and affecting the industrial water treatment effect.

[0030] The pretreatment device provided by the present application solves the problems of uneven liquid flow and uneven distribution of scale inhibitors in traditional scale inhibition technology through optimized mixing chamber design and dynamic disturbance of bubble tube. Specifically, the device of the present application can effectively improve the mixing efficiency and agent utilization rate of scale inhibitors, and ensure that the scale inhibitors are evenly distributed throughout the water treatment process. The rotating component drives the rotation of the connecting pipe and the connecting disk, and the pneumatic cavity delivers gas to the agent box, pushing the scale inhibitor into the connecting disk through the delivery pipe. The bubble tube releases gas to form turbulence, breaking the laminar flow state inside the water body, accelerating the contact and mixing of the scale inhibitor and water, and ensuring rapid and uniform mixing in the mixing chamber. The agent can be directly sprayed to the rotation center of the blade, and quickly diffused to the entire mixing chamber through the cutting action of the blade, avoiding the accumulation of agents or excessive local concentration. With the rotation of the connecting disk, the bubble tube is always in contact with the side wall of the mixing chamber by the elastic member (such as a spring). When the bubbles are sprayed, the bubbles can cover all areas in the mixing chamber well, ensuring that the bubbles are evenly distributed and effectively stir the liquid, promoting the rapid diffusion of the scale inhibitor. During the liquid release stage, the present application ensures that the bubbles stop gushing out and the agent stops outputting by precisely controlling the gas delivery and the output of the agent, thereby avoiding the adverse effects of residual bubbles entering the delivery chamber on the water treatment equipment, such as interfering with the measurement accuracy of the flow meter or increasing the complexity of the degassing step. The synchronous stop of the agent output ensures the ideal uniformity of the mixed liquid, further improving the stability of the anti-scaling effect and the reliability of the water treatment process. In addition, the continuously rotating blades maintain the dynamic fluidity of the liquid in the mixing chamber during the liquid release stage, prevent the deposition of antiscalants or other suspended particles, ensure the uniformity of liquid release and the stability of the flow rate, optimize the quality of the liquid in the delivery chamber, reduce interference in the operation of the system, and improve the operating efficiency of the device. In short, the present application not only improves the utilization efficiency of the antiscalant by optimizing the mixing, bubble release and agent gushing process, but also ensures the efficient and uniform mixing of the agent and the liquid through the disturbance of the bubbles and the rotating strong flow field, greatly improving the efficiency, stability and reliability of the water treatment process.

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] refer to Figure 1-Figure 10 , fully automatic pre-treatment air-powered anti-scaling device, including:

[0050] Pretreatment box 100;

[0051] A mixing chamber 101, a conveying chamber 110 and a pneumatic chamber 102 are provided in the pretreatment box 100, and a conveying port 103 is provided between the mixing chamber 101 and the conveying chamber 110;

[0052] A medicine box 104 is disposed in the mixing chamber 101, and one side of the medicine box 104 is connected to a delivery pipe 105;

[0053] A connecting disk 106 is disposed in the mixing chamber 101, and a plurality of bubble tubes 107 are slidably connected to the outside of the connecting disk 106, and an elastic member 108 is disposed between the bubble tubes 107 and the connecting disk 106;

[0054] A connecting pipe 111 is provided in the pre-processing box 100 , the connecting pipe 111 passes through the pre-processing box 100 and the conveying chamber 110 and extends into the pneumatic chamber 102 , and the connecting pipe 111 is in communication with the connecting plate 106 ;

[0055] A plurality of blades 109 disposed on the connecting plate 106;

[0056] A rotating component provided between the pre-treatment box 100 and the connecting pipe 111, used for rotating the connecting pipe 111;

[0057] The delivery port 103 can operate according to the following rules during the rotation of the connecting pipe 111:

[0058] When the connecting tube 111 rotates to a first preset angle, the delivery port 103 is placed in an open state;

[0059] When the connecting tube 111 rotates to a second preset angle, the delivery port 103 is placed in a closed state;

[0060] When the connecting pipe 111 rotates to the third preset angle, the delivery port 103 is placed in an open state, and the opening and closing states of the delivery port 103 are cycled in sequence according to the above rules;

[0061] The pneumatic cavity 102 can intermittently deliver gas to the connecting tube 111 and the medicine box 104 when the connecting tube 111 rotates. When the gas is delivered, the delivery port 103 is in a closed state, and when the gas stops being delivered, the delivery port 103 is in an open state.

[0062] By setting up the pretreatment box 100, when used, when the operator is performing industrial ultrapure water treatment, the water can be introduced into the mixing chamber 101 in the pretreatment box 100, and the scale inhibitor for treating the water can be put into the reagent box 104 to avoid scaling of the pipe wall during subsequent deep treatment, which affects the fluidity of the water. Specifically, the operator can use the rotating component to rotate the connecting pipe 111, and the rotation of the connecting pipe 111 can drive the connecting disk 106 connected thereto to rotate, and the rotation of the connecting disk 106 can drive the multiple blades 109 and the multiple bubble tubes 107 thereon to rotate. In this process, first, the pneumatic chamber 102 can deliver the gas therein to the connecting pipe 111 and the reagent box 104, and the scale inhibitor in the reagent box 104 can be pushed by the gas and reach the connecting disk 106 through the delivery pipe 105. The gas in the connecting pipe 111 can enter the connecting disk 106 and reach the bubble tube 107, and can be ejected from the bubble tube 107 into the mixing chamber 101. The gas ejected from the bubble tube 107 into the mixing chamber 101 will form a strong turbulence and gas-liquid contact area in the mixing chamber 101 under the action of the rotation of the blades 109. The bubbles can not only further promote the uniform dispersion of the scale inhibitor, but also disturb the liquid in the mixing chamber 101 through the rising airflow, breaking the laminar state inside the liquid, so that the scale inhibitor and water are quickly mixed, thereby improving the mixing efficiency and the utilization rate of the agent. At this time, the blades 109 in the mixing chamber 101 rotate together with the connecting disk 106, and the mixing effect is further enhanced by applying shear force and stirring force to the liquid. The design of the elastic member 108 enables the bubble tube 107 to vibrate slightly with the air flow pressure during the rotation process, thereby increasing the dynamic characteristics of the bubble gushing, preventing bubbles from accumulating or gathering in the mixing chamber 101, and ensuring a more uniform gas distribution. In addition, the delivery pipe 105 is extended to the top of the connecting disk 106, which is closer to the blades 109. When the connecting disk 106 and the blades 109 rotate, the medicine can be gushed directly toward the rotating center, and the gushing of the medicine fluid interacts with the turbulent area of ​​the rotating center, further improving the mixing efficiency of the medicine and the liquid. Since the blades 109 are evenly distributed around the rotating center, their rotation will form a strong flow field with the rotating center as the core in the mixing chamber 101. After the medicine is directly gushed to the rotating center, it is cut and dispersed by the rotating blades 109, and can quickly diffuse into the entire mixing chamber 101 to form a more uniform distribution of the liquid. This design can not only effectively reduce the problem of reagent accumulation or local excessive concentration, but also further improve the contact effect between the scale inhibitor and the liquid by strengthening the local shear force. This arrangement allows the reagent fluid to fully utilize the kinetic energy generated by the rotation when entering the mixing chamber 101, reducing the demand for external energy, thereby achieving energy consumption optimization. The turbulent environment formed during the rotation, combined with the dynamic disturbance of the reagent gushing and the gas released by the bubble tube 107, allows the concentration gradient of the liquid in the mixing chamber 101 to be quickly balanced, ensuring the efficiency and stability of the water treatment process.Secondly, when the connecting pipe 111 rotates to a preset angle (i.e., one circle), the gas delivery can be stopped and the delivery port 103 can be opened. When the gas delivery stops, the bubbles can be stopped from gushing out and the output of the agent can be stopped. At this time, the liquid in the mixing chamber 101 has been evenly mixed, and the mixed liquid can be released into the delivery chamber 110. This mode of operation can effectively avoid the following problems. During the liquid release stage, if the bubbles continue to gush out, the bubbles remaining in the mixing chamber 101 enter the delivery chamber 110, which may have an adverse effect on the subsequent water treatment equipment, such as interfering with the measurement accuracy of the flow meter or increasing the complexity of the degassing step. The output of the agent is stopped synchronously during the release stage to ensure that the liquid in the mixing chamber 101 has reached an ideal uniform state before being released, thereby avoiding the agent being released to the delivery chamber 110 in advance when the concentration is not evenly distributed, resulting in unstable scale inhibition effect. This design not only improves the utilization rate of the agent, but also optimizes the continuity and reliability of the water treatment process. In addition, during the liquid release process, the rotating component is still rotating the connecting pipe 111. Although the bubbles no longer continue to gush out, the connecting disc 106 and the blades 109 are still rotating. In the liquid release stage, in addition, during the liquid release process, although the bubbles no longer continue to gush out, the rotating component still drives the connecting pipe 111, the connecting disc 106 and the blades 109 to keep rotating. This design can continuously maintain the dynamic fluidity of the liquid in the mixing chamber 101 during the release stage, and prevent the scale inhibitor or other suspended particles from stagnating and settling to the bottom during the release process. At the same time, the liquid near the delivery port 103 is disturbed by the continuous movement of the blades 109 to prevent the accumulation of impurities and blockage problems, further ensuring the uniformity of liquid release and the stability of flow rate, and improving the quality of the liquid in the delivery chamber 110. In addition, the continuous rotation of the blades 109 can also effectively reduce the interference of the turbulence of the liquid flow on the operation of the system during the release process, prepare for the dynamic transition of the next round of mixing operations, improve the consistency and efficiency of the operation of the device, and optimize the stability of the liquid release process and subsequent water treatment as a whole. Furthermore, as the connecting disk 106 rotates, the bubble tube 107 is always in contact with the side wall of the mixing chamber 101 by the elastic member 108 (such as a spring). When the bubbles are gushing, the bubbles can well cover various areas in the mixing chamber 101, ensuring that the bubbles are evenly distributed and effectively stirring the liquid, thereby promoting the rapid diffusion of the scale inhibitor. After the liquid is released, the uniformity of the liquid in the delivery chamber 110 is guaranteed, and the next step will enter the next round of processing. The continuous rotation of the rotating parts not only ensures the full and uniform distribution of the reagents during the mixing process, but also makes full preparations for the next round of water treatment operations. Through efficient liquid mixing and bubble action, each round of liquid can be processed under efficient and uniform conditions, ensuring that each round of treatment can achieve the preset effect.In subsequent operations, the rotation of the connecting pipe 111 and the precise control of gas delivery will continue to play an important role, ensuring the optimal mixing effect of the scale inhibitor and water, and promoting more efficient distribution and contact of the agent through the disturbance of bubbles. In each round of water treatment, the system can switch the working state freely, maintain the continuity and stability of the fluid, thereby greatly improving the efficiency and reliability of the entire water treatment process. In the present application, the mixed liquid of water and scale inhibitor is released immediately after mixing, and the liquid is replenished in the delivery chamber 110 to ensure the uniform mixing of the scale inhibitor and water and effectively transfer to the area to be treated. In the water treatment process, for the working conditions of circulating flow, the present application enables the scale inhibitor to be evenly distributed in the entire flow system through the optimized design of the mixing chamber 101 and the dynamic action of the bubble tube 107. The synergistic effect of the rotating disk and the blades 109 enhances the stirring of the liquid and the disturbance of the bubbles, further ensuring the full contact between the scale inhibitor and the water. Compared with the pretreatment scale inhibitor in the prior art, it avoids the uneven distribution of scale inhibitors in the traditional technology due to uneven flow or low local flow rate.

[0063] As a further solution of the present invention, the rotating component includes a sleeve 200 connected to the connecting pipe 111, a cut-off port 201 is provided between the connecting pipe 111 and the sleeve 200, the sleeve 200 is connected to the connecting plate 106, a motor 202 is connected to the pretreatment box 100, and a driving shaft of the motor 202 is connected to the sleeve 200;

[0064] By setting the motor 202, the motor 202 is connected to the sleeve 200 through its drive shaft, and the rotation of the sleeve 200 is controlled, so as to drive the connecting pipe 111, the connecting disk 106, and the multiple blades 109 and the bubble tube 107 attached to the connecting disk 106 to rotate. The operation of the motor 202 can adjust the rotation speed and direction as needed to adapt to different water treatment needs. In addition, the sleeve 200 is arranged on the connecting pipe 111, and the two are connected through the cut-off port 201. When the gas enters the connecting pipe 111, it can enter the sleeve 200 through the cut-off port 201, and the sleeve 200 is guided. The gas can enter the connecting disk 106 and the bubble tube 107. The position of the cut-off port 201 is relatively high. This setting can avoid the problem that the liquid refluxes in the connecting pipe 111 when the bubble is no longer output due to the bubble tube 107 connecting the connecting disk 106 and the mixing chamber 101, and avoids the backflow of the liquid when the bubble is no longer gushing out, thereby optimizing the distribution process of the gas and the agent.

[0065] As a further solution of the present invention, a push plate 203 is provided in the pneumatic chamber 102, a threaded tube 204 is connected to the top of the push plate 203, a reciprocating screw 205 threadedly connected to the threaded tube 204 is connected to the bottom of the connecting tube 111, air holes a206 with a height higher than the push plate 203 are opened on both sides of the pneumatic chamber 102, a connecting rod 207 slidably connected to the reciprocating screw 205 is rotatably connected to the top of the push plate 203, a baffle 208 is provided on the connecting rod 207, a baffle ring a209 is provided at the bottom of the baffle 208, a baffle ring b210 is provided at the top of the baffle 208, and the baffle ring a209 and the baffle ring b210 are connected to the connecting tube 111;

[0066] By setting the push plate 203, in the initial state, the push plate 203 is at the lowest end of the pneumatic chamber 102, and when the connecting tube 111 rotates one circle, the push plate 203 can be moved upward to the extreme position through the reciprocating screw 205 and the threaded tube 204, and when the push plate 203 passes through and covers the air hole a206 and continues to move upward, the gas can be pushed into the reciprocating screw 205 and the connecting tube 111 through the threaded tube 204, and when the push plate 203 moves upward, the push plate 203 can allow the baffle 208 to leave the baffle ring a209 through the connecting rod 207, and at this time the gas can pass through the baffle 208 and enter the connecting disk 106, thereby realizing the gas transportation. As the connecting tube 111 continues to rotate, when the push plate 203 is reset downward, the baffle 208 can be timely re-set with the baffle ring a209, which can avoid the liquid being attracted into the connecting tube 111 due to the negative pressure. This design effectively controls the flow path of the gas and the reflux of the liquid through the movement of the push plate 203 in coordination with the action of the connecting rod 207 and the baffle 208. When the push plate 203 rises, the gas can smoothly enter the connecting disk 106, ensuring that the gas is smoothly transported to the mixing chamber 101. When the push plate 203 moves downward, the baffle 208 cooperates with the baffle ring a209 to avoid the reflux of the liquid caused by the negative pressure, ensuring the stability of the liquid flow and the precise delivery of the gas. This design makes the delivery of gas more reliable, while preventing the reflux of the liquid when the gas stops being delivered, thereby improving the overall work efficiency and reliability of the system.

[0067] As a further solution of the present invention, a plurality of limiting grooves 211 are provided on the side wall of the connecting rod 207, and a baffle 208 is slidably connected to the limiting groove 211. A damping groove 212 is provided on one side of the limiting groove 211, and the damping groove 212 is a semi-spherical groove. A damping rod 213 matching the damping groove 212 is slidably connected to the baffle 208, and one end of the damping rod 213 is a semi-spherical shape matching the damping groove 212, and a spring a214 is connected between the damping rod 213 and the baffle 208;

[0068] By setting the spring a214, the spring a214 can give the damping rod 213 and the damping groove 212 a force that matches, when the connecting rod 207 moves upward, the damping rod 213 and the damping groove 212 can make the baffle 208 move upward, and the set baffle ring b210 can limit the moving distance of the baffle 208. When the baffle 208 reaches the position of the baffle ring b210, since the push plate 203 continues to move, the potential energy of the spring a214 can be overcome at this time, so that the damping groove 212 and the damping rod 213 are separated, and the connecting rod 207 can slide on the baffle 208. The purpose of this setting is to ensure that the push plate 203 has a sufficient moving distance to push the gas, limit the moving distance of the baffle 208, and in the subsequent process of the push plate 203 resetting downward, timely close the bottom of the connecting pipe 111 to avoid the problem that the suction force generated by the resetting of the push plate 203 causes the liquid to be sucked into the connecting pipe 111.

[0069] As a further solution of the present invention, an air inlet pipe 215 is connected to the pneumatic chamber 102, and one end of the air inlet pipe 215 is connected to the medicine box 104;

[0070] By setting up the air inlet pipe 215, when the push plate 203 moves upward to push the gas, part of the gas can enter the connecting pipe 111, and part of the gas can reach the medicine box 104 through the air inlet pipe 215 to push the medicine in the medicine box 104 into the delivery pipe 105, so as to replenish the scale inhibitor for the liquid in the mixing chamber 101.

[0071] As a further solution of the present invention, the outside of the connecting tube 111 is connected with a gear a300, which is located in the delivery chamber 110. The bottom of the delivery chamber 110 is rotatably connected with a closed ring 301, and a connection port 302 adapted to the delivery port 103 is opened on the closed ring 301. The inner wall of the closed ring 301 is connected with a gear b303. The top of the delivery chamber 110 is connected with a gear c304 meshing with the gear b303 and the gear a300. The gear a300 is an incomplete gear.

[0072] By setting the gear a300, when the connection tube 111 rotates a preset angle, the gear a300 meshes with the gear c304 and drives the gear c304 to rotate, so that the gear b303 rotates with the closed ring 301. When the closed ring 301 rotates a preset angle, so that the connection port 302 and the delivery port 103 are docked and connected, the gear a300 disengages from the gear c304 to release the liquid. According to the design, the switch state of the delivery port 103 changes according to the rotation angle of the connection tube 111. For example, when the connection tube 111 rotates to the first circle, the delivery port 103 is in an open state, and the liquid can flow out smoothly; when the connection tube 111 rotates to the second circle, the delivery port 103 is in a closed state, and the liquid stops outputting; when the connection tube 111 rotates to the third circle, the delivery port 103 is in an open state again, and the liquid is released again. This design ensures the precise control and release process of the liquid, avoids excessive or unstable liquid delivery, and ensures the efficiency and reliability of the water treatment process. At the same time, the rotation angle of the closed ring 301 and the meshing accuracy of the gears can ensure that the switch operation of the delivery port 103 is accurate and correct, and the stable regulation of the liquid flow rate during the water treatment process is achieved. It is worth noting that every time the connecting tube 111 rotates one circle to allow the closed ring 301 to rotate the preset angle to open the delivery port 103, the push plate 203 moves upward to the limit position. When the connecting tube 111 continues to rotate, the push plate 203 starts to move downward, and no longer pushes the gas into the connecting tube 111 and the reagent box 104, so as to stop the gas delivery and avoid affecting the state of the mixed liquid and the problem of the continuous output of bubbles affecting the release of the liquid. In this way, the application can continuously and continuously treat the water liquid in the working condition of water flow.

[0073] As a further solution of the present invention, a liquid inlet 400 is provided on one side of the delivery tube 105, a connecting rod 401 is slidably connected in the medicine box 104, one end of the connecting rod 401 is connected to a blocking piece 402, a spring b403 is connected between the blocking piece 402 and the medicine box 104, one end of the connecting rod 401 passes through the medicine box 104 and the mixing chamber 101 and extends into the delivery chamber 110, and a top rod 404 is connected to the bottom of the closed ring 301;

[0074] By setting the push rod 404, when the closed ring 301 rotates, the connecting port 302 and the delivery port 103 are staggered, and the delivery port 103 is closed. When the release of liquid stops, the push rod 404 rotates with the closed ring 301, corresponding to the position of the connecting rod 401, and the connecting rod 401 is displaced by the push of the push rod 404, so that the blocking piece 402 can leave the liquid inlet 400. As the push plate 203 moves upward, when the gas enters the medicine chamber through the air inlet pipe 215, the medicine can be pushed into the delivery pipe 105 through the liquid inlet 400 by the pressure of the gas. By utilizing the different pressure differences between the mixing chamber 101 and the medicine box 104, the medicine can be pushed and the backflow of the liquid can be avoided. In addition, as the connecting tube 111 rotates, the closing ring 301 rotates, so that when the connecting port 302 corresponds to the delivery port 103, the top rod 404 leaves the connecting rod 401, and the connecting rod 401 and the blocking piece 402 can be reset by the force of the spring b403, and the liquid inlet 400 is closed again, so as to prevent the outflow of the medicine when releasing the liquid and affect the state of the mixed liquid.

[0075] As a further solution of the present invention, a flushing port 405 is respectively provided at the top and the bottom of the delivery pipe 105, a baffle 406 is slidably connected in the flushing port 405, a spring c407 is connected between the baffle 406 and the delivery pipe 105, a cross bar 408 is connected to one side of the blocking piece 402, and an inclined rod 409 rotatably connected to the cross bar 408 and rotatably connected to the baffle 406;

[0076] By setting a spring, the spring can limit the position of the baffle 406. When the blocking piece 402 closes the liquid inlet 400, the baffle 406 is in a state of leaving the flushing port 405, and the flushing port 405 is in an open state, which facilitates the liquid in the mixing chamber 101 to enter the delivery pipe 105 through the flushing port 405, and flush the residual liquid in the delivery pipe 105, so as to avoid the problem of incomplete mixing of the medicine in the delivery pipe 105. When the blocking piece 402 leaves the liquid inlet 400, the set cross bar 408 can move with the blocking piece 402, the inclined rod 409 is tilted, and the spring c407 releases potential energy, so that the baffle 406 and the flushing port 405 are set together. After the closed flushing, when the gas enters the medicine box 104 and the medicine enters the delivery pipe 105, the medicine can be sprayed at the blade 109, ensuring that the medicine can be effectively dispersed and mixed. This design effectively ensures the stability of each round of water treatment process, avoids the accumulation or uneven mixing of the agent in the delivery pipe 105, and at the same time allows the liquid in the delivery pipe 105 to be thoroughly cleaned, ready for the next round of water treatment operations. It is worth noting that when the delivery port 103 is opened, the flushing port 405 is also in an open state. This design ensures that the residual agent in the delivery pipe 105 is flushed while releasing the liquid. Specifically, during the liquid release process, the opening of the flushing port 405 allows the liquid in the mixing chamber 101 to enter the delivery pipe 105 through the flushing port 405, and flush the delivery pipe 105. However, it is worth noting that the outflow of the agent has stopped at this time, and the agent no longer continues to enter the mixing chamber 101 or the delivery pipe 105. Therefore, although flushing is performed, the total amount of the agent has not changed and is not affected by this process. The agent has been completely dispersed and fully mixed with water in the mixing stage, and has reached a predetermined uniform distribution during the release process, ensuring the stability of the water treatment effect. Through this design, the flushing operation is only used to clean the residual medicine in the delivery tube 105, and will not affect the uniformity of the liquid in the mixing chamber 101 or the distribution of the medicine, thereby avoiding any potential incomplete mixing problem. During the liquid release stage, the flushing operation is independent of the mixing and distribution of the medicine, ensuring that each liquid release can maintain the expected effect while avoiding medicine waste or uneven distribution.

[0077] As a further solution of the present invention, an air hole b500 is opened on the top of the medicine box 104, a stopper 501 is sleeved in the air hole b500, and a spring d502 is connected between the stopper 501 and the medicine box 104;

[0078] By setting the stopper 501 and the spring d502, a one-way air valve can be formed. And the elastic potential energy of the spring d502 is smaller than that of the spring b403. When the push plate 203 moves downward, the stopper 501 moves downward under the negative pressure to replenish air in the medicine box 104. When the push plate 203 moves upward, the position of the stopper 501 does not change, and the air hole b500 is continuously closed, so that a positive pressure is formed in the medicine box 104 to push the medicine.

[0079] As a further solution of the present invention, the top of the pretreatment box 100 is connected to a pipe a503 communicating with the mixing chamber 101, the top of the pretreatment box 100 is also connected to a pipe b504 communicating with the reagent box 104, and one side of the delivery chamber 110 is connected to a pipe c505;

[0080] By setting up pipeline a503 and pipeline b504, a channel can be provided for pretreated water and chemicals to enter the mixing chamber 101 and the chemicals box 104. When appropriate, pipeline b504 can also be closed to allow gas to enter the chemicals box 104, so that positive pressure can be formed in the chemicals box 104.

[0081] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
