Description

Technical Field

[0001] The present invention relates to the field of sewage treatment, and in particular to a sponge city sewage treatment system. Background Art

[0002] With the acceleration of urbanization, urban water shortage and water pollution problems are becoming increasingly prominent. To alleviate this problem, the concept of sponge city has been widely used in the planning and construction of urban water systems, aiming to achieve rainwater resource utilization, runoff pollution control and urban waterlogging control through measures such as "infiltration, retention, storage, purification, use and discharge". Among them, sewage treatment is an important link in the construction of sponge cities, which is directly related to the recycling of water resources and the improvement of the ecological environment.

[0003] In the process of sewage treatment, in order to improve the efficiency of sedimentation and removal of suspended solids, it is usually necessary to add flocculants to aggregate the colloidal particles into larger flocs and accelerate sedimentation. At present, the common ways of adding flocculants include: one is to rely on gravity dripping through opening and closing pipes, and control the opening and closing time and interval time to adjust the dosage; the second is to use pumps and nozzles to atomize or spray the agent into the sewage to make it evenly distributed. However, it is difficult to accurately control the dosage by gravity dripping, and the uniformity of dosage is affected by pressure fluctuations. In the pump spraying method, the sprayed agent may diffuse in the air due to unreasonable nozzle angle or too small particle size, reducing the effective dosage. On the other hand, long-term operation of the nozzle may cause uneven spraying due to agent deposition or pipeline blockage, affecting the dosage accuracy. At the same time, in the sewage pool or pipeline, the water flow is affected by the pump, agitator, etc., which may form turbulence or backflow, further interfering with the diffusion of the agent, causing it to accumulate in a specific area, resulting in uneven distribution of flocculant concentration, which not only affects the flocculation effect, but may also cause the problem of local overdose of the agent, increase agent consumption and subsequent treatment burden. In addition, the operation of the nozzle depends on the stable supply pressure of the pump. If the system pressure fluctuates greatly, it will not only affect the dosage of the agent, but also shorten the service life of the nozzle and increase the equipment maintenance cost.

[0015] In summary, the present invention mainly has the following beneficial effects: In the present application, a storage chamber and a release component a are arranged in the medium chamber. When the treatment chamber moves upward to a preset position, the release component a pushes the connecting rod to insert the storage chamber into the treatment chamber, thereby ensuring that the agent is stably released into the treatment chamber. Compared with the traditional gravity dripping method, this design is easier to control the amount of agent added, and is not affected by external pipeline pressure fluctuations, thereby improving the addition accuracy. During the movement of the treatment chamber, the mixing frame and spiral blades arranged inside can rotate simultaneously, so that the agent and sewage are fully mixed under the action of turbulence, avoiding the accumulation of agents in local areas and improving the coagulation efficiency.

[0016] In addition, the rotation of the mixing frame can enhance the dispersibility of the flocculant, make the agent evenly distributed in the sewage, and improve the stability of sewage treatment. This equipment uses the periodic vibration of the vibrating plate to keep the powder or granular agent loose in the medium cavity, reduce the adhesion between particles, and reduce the stacking resistance, thereby improving the agent filling efficiency, ensuring that the agent can smoothly enter the storage cavity and be accurately released, avoiding abnormal dosing due to blockage, and using spiral blades to accelerate the speed of sewage entering the treatment cavity. The storage cavity can be flushed with sewage, further reducing the agent residue, improving the dosing efficiency, and ensuring a balanced ratio of agent to sewage in each treatment process.

[0017] When the processing chamber moves downward to the release chamber position, the release component c is triggered to open the release port at the bottom of the processing chamber, allowing the mixed liquid to be discharged smoothly. At the same time, the inlet port is opened synchronously. Opening the inlet port can create a relatively open flow channel, allowing air or other gases to enter the processing chamber, thereby reducing the resistance of the liquid. This design can help balance the flow of the liquid, prevent flow obstruction caused by negative pressure, and enable the mixed liquid to be discharged more smoothly from the release port, preventing discharge obstruction and improving discharge efficiency.

[0018] This application can adapt to different types of sewage treatment needs. The core is to enable the agent to be accurately delivered and fully react according to the different sewage components through controllable dosing methods, dynamic mixing mechanisms and efficient release processes. Compared with the existing technology, this application has higher flexibility and adaptability in the agent dosing method. It can select the appropriate agent form according to the different sewage components, including granular, powdered or liquid agents, and ensure that it is evenly and stably added to the sewage.

[0019] To summarize, this application overcomes the problems of uneven dosage, waste of reagents, poor mixing effect, etc. existing in traditional sewage treatment devices by accurately controlling the dosage of reagents, enhancing the mixing effect, optimizing the release process, and adapting to different sewage treatment needs. It improves the efficiency and stability of sewage treatment, reduces maintenance costs, and provides an efficient, stable, and controllable technical solution for sewage purification.

DETAILED DESCRIPTION

[0022] 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.

[0023] refer to Figure 1-Figure 10 , a sponge city sewage treatment system, comprising: Processing box 100; A medium chamber 101, a sewage chamber 102, a processing chamber 103 and a release chamber 104 are arranged in the processing box 100. A mixing frame 105 is arranged in the processing chamber 103. A vibration plate 106 is arranged at the bottom of the medium chamber 101. The capacity of the sewage chamber 102 is smaller than that of the processing chamber 103. An inlet 107 is provided at the top of the processing chamber 103, and a release port 108 is provided at the bottom of the processing chamber 103; A plurality of connecting rods 109 are disposed in the medium cavity 101, and a storage cavity 114 is provided at the bottom of the connecting rods 109 to temporarily store the medium; A sewage outlet 110 is provided at the bottom of the sewage chamber 102, and a spiral blade 111 is provided therein; A release component a disposed between the processing chamber 103 and the medium chamber 101 is used to push the connecting rod 109 when the processing chamber 103 moves upward to a preset position, and to insert the storage chamber 114 into the processing chamber 103. The release component a can reset the connecting rod 109 when the processing chamber 103 moves downward to a preset position; The release component b disposed between the treatment chamber 103 and the sewage chamber 102 is used to open the inlet 107 and the sewage outlet 110 when the treatment chamber 103 moves upward to a preset position, so that the sewage enters the treatment chamber 103; The release component c disposed between the processing chamber 103 and the release chamber 104 is used to open the release port 108 and the inlet port 107 when the processing chamber 103 moves downward to a preset position, so that the mixed liquid enters the release chamber 104; The moving part provided in the processing box 100 is used to drive the processing chamber 103 to move up and down and act on the vibration plate 106 to move up and down; The moving component can rotate the mixing frame 105 and the spiral blade 111 when moving the processing chamber 103 , and continue to drive the mixing frame 105 and the spiral blade 111 to rotate after the processing chamber 103 moves to a preset position.

[0024] By setting the medium chamber 101 and the sewage chamber 102, when used, the sewage to be treated can be first introduced into the sewage chamber 102, and the medium for purifying sewage can be filled into the medium chamber 101, wherein the medium can include purification agents in granular, powdered or liquid form to meet different sewage treatment needs. Granular agents are usually composed of polymer flocculants, ion exchange resins or activated carbon particles, which can be slowly released in sewage or provide a large specific surface area to adsorb pollutants; powdered agents such as aluminum sulfate, polyaluminum chloride (PAC) or powdered activated carbon can quickly dissolve and fully mix with sewage to improve coagulation, adsorption or oxidation efficiency. Liquid agents include iron salts, aluminum salt flocculants, hydrogen peroxide, potassium permanganate, etc. The addition method can select a suitable solution according to the characteristics of the sewage and treatment requirements. Specifically, the operator can start the moving component to move the processing chamber 103 upwards close to the medium chamber 101 and the sewage chamber 102. During this process, the mixing frame 105 and the spiral blade 111 can rotate, and the vibration plate 106 can move up and down. The up and down movement of the vibration plate 106 can help the medium in the medium chamber 101 enter the storage chamber 114, and the method includes the periodic vibration of the vibration plate 106 to generate an upward thrust, loosen the medium and reduce the adhesion between particles, thereby reducing the stacking resistance. In addition, the vibration can cause the powder or particles to flow along the entrance direction of the storage chamber 114, thereby improving the filling efficiency. When the processing chamber 103 moves upward to the preset position, the release component a set pushes the connecting rod 109 to insert the storage chamber 114 into the processing chamber 103, and the release component b opens the inlet 107 and the sewage outlet 110, so that the medium in the storage chamber 114 is released into the processing chamber 103, and enters the processing chamber 103 synchronously with the sewage in the sewage chamber 102. When the storage chamber 114 is inserted into the treatment chamber 103 and the sewage is released into the treatment chamber 103, the medium in the storage chamber 114 can slide or flow out due to gravity, and be further dispersed under the flushing of the sewage, which helps to clean the medium in the storage chamber 114, avoid the problem of residual and insufficient release, and ensure that the amount of medium added each time is in a suitable ratio with the amount of sewage, so as to achieve the best coagulation, adsorption or oxidation effect. In addition, when the treatment chamber 103 moves upward to the preset position and stops receiving drugs and sewage, the mixing frame 105 and the spiral blade 111 can continue to rotate. This continuous rotation action can not only enhance the release of the agent in the storage chamber 114, ensure that the medium is evenly dispersed in the sewage, but also enhance the power of the water flow, so as to promote the mixing of sewage and the agent more quickly and effectively. By enhancing the flushing effect, the retention of the agent in the storage chamber 114 can be effectively prevented, the reaction rate can be improved, and the treatment efficiency and effective use of the agent can be ensured. The spiral blade 111 is designed to rotate to increase the speed at which sewage enters the treatment chamber 103 from the sewage chamber 102. The shape and arrangement of the spiral blade 111 cause the water flow to rotate when passing through the spiral blade 111, thereby forming an effective flow channel.This rotation not only enhances the power of the water flow, but also creates local negative pressure and promotes the rapid transportation of sewage. As the flow rate of sewage increases, it can accelerate the mixing with the medium and improve the efficiency of the reaction. At the same time, the rotation of the spiral blade 111 also helps to evenly distribute the suspended matter in the sewage, ensure that the fluid state in the entire treatment chamber 103 is more uniform, and further optimize the effect of sewage treatment. After stopping the movement of the treatment chamber 103 to ensure that all sewage enters the treatment chamber 103, the moving part starts to drive the treatment chamber 103 to move downward. During this process, the inlet 107 and the sewage outlet 110 are closed, and sewage can be poured into the sewage chamber 102 again for the next round of treatment. When the treatment chamber 103 moves downward to the position of the release chamber 104, the release part c is triggered to open the release port 108 at the bottom of the treatment chamber 103, so that the mixed liquid is smoothly discharged into the release chamber 104, and the inlet 107 can also be opened. Opening the inlet 107 can create a relatively open flow channel, allowing air or other gases to enter the treatment chamber 103, thereby reducing the resistance of the liquid. This design can help balance the flow of liquid, prevent flow obstruction caused by negative pressure, and enable the mixed liquid to be discharged more smoothly from the release port 108. At the same time, the entry of gas can break the tension on the surface of the liquid, make the liquid flow more smoothly, and reduce the impact of viscosity. By opening the release port 108 and the inlet port 107 at the same time, the flow rate of the mixed liquid can be effectively improved, the discharge time can be shortened, and the efficiency and continuity of the treatment process can be ensured. This design not only improves work efficiency, but also ensures that the release of the liquid can be completed quickly after each treatment, so as to prepare for subsequent treatment links. In addition, in the process of the processing chamber 103 moving downward, the mixing frame 105 provided can rotate, and this rotation action helps to further improve the fluidity and uniformity of the mixed liquid. The rotating mixing frame 105 can effectively break the laminar state in the liquid and promote the full mixing between different components by forcibly stirring the mixed liquid. Specifically, the rotation of the mixing frame 105 will generate eddy currents in the mixed liquid, forming multiple flow cycles, so that the suspended matter and the agent in the liquid can be dispersed and fused faster. This not only enhances the reaction efficiency of the agent, but also improves the removal effect of pollutants in sewage.

[0025] In the present application, a storage chamber 114 and a release component a are arranged in the medium chamber 101. When the treatment chamber 103 moves upward to a preset position, the release component a pushes the connecting rod 109 to insert the storage chamber 114 into the treatment chamber 103, thereby ensuring that the agent is stably released into the treatment chamber 103. Compared with the traditional gravity dripping method, this design is easier to control the amount of agent delivered, and is not affected by the pressure fluctuation of the external pipeline, thereby improving the dosing accuracy. During the movement of the treatment chamber 103, the mixing frame 105 and the spiral blade 111 arranged inside can rotate at the same time, so that the agent and sewage are fully mixed under the action of turbulence, avoiding the aggregation of the agent in a local area and improving the coagulation efficiency. In addition, the rotation of the mixing frame 105 can enhance the dispersibility of the flocculant, so that the agent is evenly distributed in the sewage, and the stability of sewage treatment is improved. The traditional nozzle spraying method is easily affected by the deposition of the agent, resulting in nozzle blockage or uneven dosing. This device maintains the powder or granular medicine in a loose state in the medium cavity 101 through the periodic vibration of the vibration plate 106, reduces the adhesion between particles, reduces the stacking resistance, thereby improving the filling efficiency of the medicine, ensuring that the medicine can smoothly enter the storage cavity 114 and be accurately released, avoiding abnormal addition caused by blockage, and using the spiral blade 111 to accelerate the speed of sewage entering the treatment cavity 103. The storage cavity 114 can be flushed with sewage to further reduce the residual medicine, improve the addition efficiency, and ensure that the ratio of medicine to sewage is balanced during each treatment process. When the treatment cavity 103 moves downward to the release cavity 104 position, the release component c is triggered to open the release port 108 at the bottom of the treatment cavity 103, so that the mixed liquid can be discharged smoothly. At the same time, the inlet port 107 is opened synchronously. Opening the inlet port 107 can create a relatively open flow channel, allowing air or other gases to enter the treatment cavity 103, thereby reducing the resistance of the liquid. This design can help balance the flow of liquid, prevent flow obstruction caused by negative pressure, and enable the mixed liquid to be discharged more smoothly from the release port 108, preventing discharge obstruction and improving discharge efficiency. The present application can adapt to different types of sewage treatment needs. Its core lies in the controllable addition method, dynamic mixing mechanism and efficient release process, so that the agent can be accurately delivered and fully reacted according to the different components of sewage. For example, for sewage containing a large number of suspended particles, granular or powdered polymer flocculants can be used to enhance the bridging effect between particles and increase the sedimentation rate; for sewage containing soluble pollutants, liquid oxidants or precipitants, such as potassium permanganate or iron salts, can be selected to promote the degradation of pollutants or form insoluble precipitates. Compared with the prior art, the present application has higher flexibility and adaptability in the method of agent addition, and can select suitable agent forms according to different sewage components, including granular, powdered or liquid agents, and ensure that they are evenly and stably added to the sewage.In summary, this application overcomes the problems of uneven dosage, waste of reagents, poor mixing effect, etc. existing in traditional sewage treatment devices by accurately controlling the dosage of reagents, enhancing the mixing effect, optimizing the release process, and adapting to different sewage treatment needs. It improves the efficiency and stability of sewage treatment, reduces maintenance costs, and provides an efficient, stable, and controllable technical solution for sewage purification.

[0026] As a further solution of the present invention, the moving part includes a screw a200 rotatably connected to the processing box 100, the processing chamber 103 is threadedly connected to the screw a200, a motor 201 is provided in the processing box 100, the driving shaft of the motor 201 is connected to the screw a200, and the processing box 100 is also rotatably connected to a connecting shaft 202, the connecting shaft 202 passes through the processing chamber 103, and a spline a203 is provided on the connecting shaft 202. A gear a204 is rotatably connected in the processing chamber 103, and the gear a204 is slidably connected to the spline a203. The side wall of the mixing frame 105 is connected to a gear b205 meshing with the gear a204, and the screw a200 and the connecting shaft 202 are provided with gears c206 meshing with each other.

[0027] By setting the motor 201, by setting the motor 201, the screw a200 can be driven to rotate, so that the processing chamber 103 moves up and down along the threaded structure of the screw a200. When the motor 201 drives the screw a200 to rotate, the processing chamber 103 moves axially therewith, and at the same time, since the screw a200 and the connecting shaft 202 are provided with a gear c206 that meshes with each other, the connecting shaft 202 rotates synchronously during the movement of the processing chamber 103. The rotation of the connecting shaft 202 rotates the gear a204 through the spline a203, and further rotates the gear b205, thereby driving the mixing frame 105 to rotate. The purpose of arranging the spline a203 is that in the process of allowing the processing chamber 103 to move up and down, the gear b205 can follow the movement and slide on the connecting shaft 202, and can still be driven by the rotation of the connecting shaft 202 and rotate synchronously, thereby ensuring that the mixing frame 105 always keeps a rotating state during the movement of the processing chamber 103, so that the medicament and the sewage can be continuously and evenly mixed. The advantage of this design is that even if the processing chamber 103 is at different heights, the mixing frame 105 can still maintain effective rotation and stirring, avoiding the decrease in stirring efficiency caused by height changes. At the same time, due to the spline structure, the gear b205 can adaptively adjust its position when the processing chamber 103 moves, reducing the possible jamming problem caused by the rigid connection and improving the stability and durability of the overall transmission system.

A connecting groove 210 is provided at the bottom of the partition a207, and the gear c206 is located in the connecting groove 210 to avoid the processing chamber 103.

The top of the connecting shaft 202 extends to the inner top surface of the processing box 100, and a spring b213 is connected to the processing box 100. The top of the processing chamber 103 is connected to a top contact frame 214. A spline b215 is also provided on the connecting shaft 202, and the gear c206 is slidably connected to the spline b215. A connecting pipe 216 is connected in the sewage outlet 110, and the spiral blade 111 is rotatably connected to the connecting pipe 216. A chain transmission mechanism 217 is provided between the shaft of the spiral blade 111 and the connecting shaft 202. In this embodiment, the spring b213 is a torsion spring.

[0029] Furthermore, in order to prevent the gear c206 on the connecting shaft 202 from meshing with the gear c206 on the screw a200 when it moves downward, a limit baffle can be set on the connecting shaft 202. When the gear c206 on the connecting shaft 202 moves downward and is limited on the baffle, the two gears c206 are just meshed. The baffle is only set in the middle of the gear c206 to avoid obstruction to the top contact frame 214.

[0030] By setting the spring b213, when the lead screw a200 rotates through the two gears c206 to drive the connecting shaft 202 to rotate, the spring b213 can be twisted to generate potential energy. When the processing chamber 103 moves upward to the limit position, the top contact frame 214 can contact the gear c206 on the connecting shaft 202 and touch the gear c206, so that the gear c206 on the connecting shaft 202 moves upward and disengages from the gear c206 on the lead screw a200, and the spring a212 is compressed to generate potential energy. When the two gears c206 do not mesh, the potential energy of the spring b213 is released, thereby driving the connecting shaft 202 to rotate in the opposite direction. The purpose of this setting is that even if the processing chamber 103 has stopped moving at this time, the mixing frame 105 can still perform additional rotation and mixing to improve the full contact between the reagent and the sewage. And it can produce the effect of allowing the sewage to flush the storage chamber 114. In addition, the spring a212 is in a compressed state when the gear c206 is touched. When the processing chamber 103 moves downward again, the restoring force of the spring a212 will push the gear c206 back to its original position, so that it meshes with the gear c206 on the lead screw a200 again, thereby restoring the normal rotation drive of the connecting shaft 202, so that the entire system can continuously and stably perform mixing operations. This design can not only maintain the rotation of the mixing frame 105 during the movement of the processing chamber 103, but also extend the mixing time at the moment when the processing chamber 103 stops moving, ensure uniform distribution of the reagent, improve the effect of coagulation or reaction, and thus enhance the efficiency and stability of sewage treatment. By setting a chain transmission mechanism 217, the axis of the spiral blade 111 is synchronized with the rotation of the connecting shaft 202, so as to realize the linkage rotation of the mixing frame 105 and the spiral blade 111. When the connecting shaft 202 is driven to rotate by the lead screw a200 and the gear c206, the chain transmission mechanism 217 transmits the rotational motion to the spiral blade 111, causing it to rotate synchronously, thereby accelerating the speed at which the sewage enters the treatment chamber 103, and providing additional disturbance during the flow of sewage, thereby enhancing the diffusion effect of the agent. In addition, after the treatment chamber 103 moves upward to the preset position, the spring b213 releases potential energy to drive the connecting shaft 202 to continue rotating, and the chain transmission mechanism 217 also synchronously drives the spiral blade 111 to continue rotating. Even if the treatment chamber 103 has stopped moving and is receiving the medium and sewage, the spiral blade 111 can still rotate. This design ensures that the sewage is fully stirred and accelerated during the process of entering the treatment chamber 103. This setting helps to reduce the flow resistance of the sewage when entering the treatment chamber 103, so that the sewage can enter the treatment chamber 103 more smoothly through the connecting pipe 216, thereby improving the sewage transportation efficiency. The sewage can maintain a certain fluidity before entering the treatment chamber 103 to prevent the sedimentation caused by the accumulation of suspended particles or sediments in the sewage chamber 102 .

[0031] As a further solution of the present invention, the release component a includes a plurality of limit rods 300 connected to the outer wall of the partition tube 208, the connecting rod 109 is slidably connected to the limit rod 300, a spring c301 is connected between the limit rod 300 and the connecting rod 109, a through hole 302 is provided at the bottom of the partition a207, the connecting rod 109 is slidably connected in the through hole 302, a positioning groove 303 is provided on the outer wall of the connecting rod 109, a connecting groove 304 is provided between the connecting groove 210 and the through hole 302, a positioning rod 305 adapted to the positioning groove 303 is slidably connected in the connecting groove 304, and the connecting groove 304 is provided with a positioning rod 305 adapted to the positioning groove 303. A push rod 306 is slidably connected in the connecting groove 210, a spring d307 for limiting the position of the push rod 306 is connected between the push rod 306 and the connecting groove 210, a spring e308 for limiting the positioning rod 305 is connected between the positioning rod 305 and the connecting groove 304, a traction rope a309 is connected between the positioning rod 305 and the push rod 306, a delivery port 310 is opened at the top of the processing chamber 103, a stopper 311 is sleeved in the delivery port 310, a spring telescopic rod 312 is connected between the stopper 311 and the processing chamber 103, and the potential energy of the spring c301 is greater than the potential energy of the spring telescopic rod 312.

[0032] By setting the spring c301, in the initial state, the spring c301 is in a compressed state, and the positioning rod 305 is inserted into the positioning groove 303, which can limit the position of the connecting rod 109, ensuring that the storage chamber 114 will not protrude from the partition a207 and cause leakage. When the processing chamber 103 moves upward to the limit position, the gear c206 on the connecting shaft 202 moves upward and disengages from the gear c206 on the lead screw a200 through the top contact frame 214. As the gear c206 moves, it can contact the bottom of the top rod 306 and press the top rod 306 to force the top rod 306 to move upward. When the top rod 306 moves, it can pull the positioning rod 305 through the traction rope, so that the positioning rod 305 can be disengaged from the positioning groove 303. At this time, the compression potential energy of the spring c301 is released, pushing the connecting rod 109 to slide along the limiting rod 300, so that the storage chamber 114 moves downward and reaches the position of the stopper 311 through the insertion port 302. Since the potential energy of the spring c301 is greater than the spring telescopic rod 312, the bottom of the connecting rod 109 will press the stopper 311, forcing the stopper 311 to move and open the delivery port 310. The storage chamber 114 on the connecting rod 109 can enter the processing chamber 103 through the delivery port 310, achieving the purpose of automatically releasing the medium into the processing chamber 103. In the process of the storage chamber 114 releasing the medium, the potential energy of the spring c301 ensures that the storage chamber 114 moves downward stably, avoids violent shaking or tilting during the medium delivery process, and ensures the uniformity of delivery. When the storage chamber 114 completely reaches the position of the delivery port 310 and completes the medium release, the processing chamber 103 can be driven by the moving parts to reset and move downward. During this process, the spring telescopic rod 312 gradually restores its extended state, pushes the stopper 311 to reset upward, and recloses the delivery port 310 to prevent the liquid in the processing chamber 103 from leaking. At the same time, during the downward movement of the processing chamber 103, the top contact frame 214 gradually disengages from the gear c206, and the gear c206 returns to the initial position under the restoring force of the spring a212, and re-engages with the gear c206 on the lead screw a200, so that the connecting shaft 202 resumes the rotation drive. This design enables the medium to be automatically delivered at the right time through the combined action of the spring c301, spring e308 and spring telescopic rod 312, while ensuring that the storage chamber 114 remains fixed in the non-delivery state to avoid leakage or accidental release, further improving the delivery accuracy and treatment efficiency of the agent in the sewage treatment process. In addition, the automatic reset function of the structure ensures that the entire system can operate continuously and stably without additional manual intervention, thus improving the automation level of the equipment.

[0033] As a further solution of the present invention, the release component a further comprises a connection chamber 313 opened in the connection rod 109, a traction shaft 314 is rotatably connected in the connection chamber 313, a spring f315 is connected between the traction shaft 314 and the connection chamber 313, a traction rope b316 is connected to the top of the processing chamber 103, one end of the traction rope b316 passes through the partition tube 208 and the limit rod 300 and extends into the connection chamber 313, and is wound around the traction shaft 314. In this embodiment, the spring f315 is a torsion spring.

[0034] By setting a traction rope b316, one end of the traction rope b316 is wound on the traction shaft 314, and the other end is connected to the processing chamber 103, and the bent part in the middle is turned through a fixed pulley to reduce friction. In the initial state, the traction rope b316 is wound on the traction shaft 314. When the connection rod 109 is released from the limit, the spring c301 can overcome the force of the spring f315, so that the traction shaft 314 rotates to release the traction rope b316, providing the conditions for the connection rod 109 to move downward. In the process of the subsequent moving parts driving the processing chamber 103 to move downward, since the potential energy of the spring c301 is greater than that of the spring f315, when the processing chamber 103 initially moves, the traction rope b316 will not pull the traction shaft 314 to allow the connecting rod 109 to return upward. At this time, the traction rope b316 will use the traction force to rotate the traction shaft 314 in the connecting chamber 313 and allow the spring f315 to twist to generate potential energy. When the processing chamber 103 moves downward until the traction rope b316 is completely released, , the continued movement of the treatment chamber 103 can pull the traction shaft 314 through the traction rope b316, so that the connecting rod 109 can be reset upward. When the connecting rod 109 moves upward so that the positioning groove 303 corresponds to the positioning rod 305, the energy stored in the previous spring e308 and spring f315 is released, so that the positioning rod 305 can cooperate with the positioning groove 303 again, so that the connecting rod 109 is re-positioned, ensuring that the storage chamber 114 is stably fixed on the partition a207, ready for the next operation. The whole process ensures the coordinated synchronization of the medium release and the reset of the storage chamber 114 through the energy conversion of the spring c301 and the spring f315, and the sequential release and recovery of the traction rope b316, so that the treatment chamber 103 can efficiently and continuously perform sewage treatment operations. It is worth noting that the purpose of allowing the processing chamber 103 to leave the connecting rod 109 and then allowing the connecting rod 109 to generate a reset action is that when the processing chamber 103 moves upward to the extreme position to receive the release of the medium, the processing chamber 103 is in close contact with the partition a207, the delivery port 310 and the insertion port 302 are connected, and the vertical height of the storage chamber 114 is lower than the height of the combination of the partition a207 and the processing chamber 103. If the connecting rod 109 is reset when the delivery port 310 is received and the processing chamber 103 has not moved downward, the outer wall of the storage chamber 114 is in a closed state when passing through the delivery port 310 and the insertion port 302, and the air cannot smoothly enter the storage chamber 114. Since the storage chamber 114 is in contact with the sewage during delivery, when the storage chamber 114 leaves, the sewage in it cannot flow out smoothly, and the sewage will also enter the medium chamber 101. Therefore, it is necessary to ensure that the processing chamber 103 moves downward first to form a certain space between the processing chamber 103 and the partition a207, and then reset the connecting rod 109 to prevent sewage from flowing back into the medium chamber 101 and affecting the purity of the medium.

[0035] As a further solution of the present invention, the release component b includes a plurality of connection ports 400 opened on the partition a207, which are connected to the sewage outlet 110, the axis of the spiral blade 111 extends into the sewage outlet 110, a plurality of baffles 401 are slidably connected in the connection port 400, one end of the baffle 401 is in contact with the axis of the spiral blade 111, and the combination of the baffle 401 and the axis of the spiral blade 111 can close the sewage outlet 110, a lead screw b402 is rotatably connected in the connection port 400, the baffle 401 is threadedly connected to the lead screw b402, a gear d403 is provided on the lead screw b402, a spring g404 is connected between the gear d403 and the connection port 400, a ratchet mechanism 405 is provided between the gear d403 and the lead screw b402, a rack 406 meshing with the gear d403 is slidably connected in the connection port 400, and a spring h407 is connected between the rack 406 and the connection port 400. In this embodiment, the spring g404 is a torsion spring.

[0036] By setting the rack 406, in the initial state, the rack 406 is meshed with the gear d403, and the spring h407 can limit the position of the rack 406. When the processing chamber 103 moves upward to the preset position, it can contact the rack 406 and touch the rack 406 to make it move. The meshing relationship between the rack 406 and the gear d403 can make the gear d403 rotate. At this time, the spring g404 is twisted to generate potential energy, and the ratchet mechanism 405 can be idle outside the lead screw b402 when the gear d403 rotates this time. When the processing chamber 103 moves upward to the limit position, the rack 406 moves upward to the preset position and will be separated from the gear d403. At this time, the spring g404 releases the potential energy to make the gear d403 rotate in the opposite direction. The ratchet mechanism 405 can drive the lead screw b402 to rotate in the opposite rotation of the gear d403, so as to make the baffle 401 displaced, thereby achieving the purpose of opening the sewage outlet 110. After the sewage is subsequently released into the treatment chamber 103, the treatment chamber 103 will gradually move away from the partition a207 during the process of resetting downward. At this time, the potential energy of the spring h407 generated by the movement of the rack 406 is released, allowing the rack 406 to move downward. At this time, the screw b402 can be rotated again through the gear d403 and the ratchet mechanism 405 to allow the baffle 401 to move backward and close the sewage outlet 110 again to prevent sewage from overflowing and leaking when sewage is poured into the sewage chamber 102 again.

[0037] As a further solution of the present invention, the release component b further includes a connecting frame 408 connected to the entrance 107, a through hole 409 is provided on the connecting frame 408, a baffle 410 is rotatably connected to the top of the through hole 409, a spring i411 is connected between the baffle 410 and the through hole 409, a traction rope c412 is wound on the axis of the baffle 410, one end of the traction rope c412 passes through the connecting frame 408 and extends to the bottom of the connecting frame 408, a vertical shaft 413 is slidably connected to the connecting frame 408, a spring j414 is connected between the vertical shaft 413 and the connecting frame 408, a guide tube 415 is connected to the bottom of the connecting frame 408, and one end of the traction rope c412 passes through the guide tube 415 and is connected to the vertical shaft 413. In this embodiment, the spring i411 is a torsion spring.

[0038] By setting the baffle 410, in the initial state, the baffle 410 can close the opening 409 to prevent the overflow and leakage of sewage in the processing chamber 103. When the processing chamber 103 moves upward to the position close to the axis of the spiral blade 111, the vertical shaft 413 can contact the axis of the spiral blade 111, and under the restriction of the axis of the spiral blade 111, the vertical shaft 413 will slide on the connecting frame 408 and pull the traction rope c412, which can rotate the baffle 410 to open the opening 409. With the opening of the sewage outlet 110, the sewage can smoothly pass through the opening 409 into the sewage outlet 110, and then enter the processing chamber 103 for further treatment. After the treatment chamber 103 completes the sewage receiving task, when the treatment chamber 103 moves downward to reset, the vertical axis 413 gradually leaves the axis of the spiral blade 111. At this time, the spring j414 releases its accumulated potential energy, causing the vertical axis 413 to reset and move. At the same time, the traction rope c412 relaxes, and the baffle 410 returns to its original position under the action of the spring i411, and the opening 409 is reclosed to ensure that the sewage will not continue to leak out.

[0039] As a further solution of the present invention, the release component c includes a blocking tube 500 slidably connected to the release port 108, a plurality of connecting holes a501 are provided on the side wall of the blocking tube 500, a spring k502 is connected between the blocking tube 500 and the processing chamber 103, a release tube 503 connected to the release chamber 104 is connected to the top of the partition b209, a plurality of connecting holes b504 matching the connecting holes a501 are provided on the outer wall of the release tube 503, and the bottom of the vertical axis 413 extends to the position of the blocking tube 500 and is slidably connected to the blocking tube 500.

[0040] By setting the blocking tube 500, the blocking tube 500 cooperates with the spring k502 to close the release port 108. When the processing chamber 103 moves downward to the position of the release tube 503 under the driving of the moving part, the release tube 503 will touch the blocking tube 500, allowing the blocking tube 500 to move, and allowing the connecting hole a501 to communicate with the internal cavity of the processing chamber 103. At this time, the mixed sewage liquid in the processing chamber 103 can flow into the release chamber 104 through the connecting hole a501 and the connecting hole b504 to wait for sedimentation or other treatment. In addition, when the release tube 503 touches the blocking tube 500 to cause the blocking tube 500 to be displaced, it will also touch the vertical shaft 413 to move the vertical shaft 413, so as to rotate the baffle 410 through the traction rope c412 to open the inlet 409, so that when the sewage is released, air can enter the processing chamber 103, thereby avoiding the slow release of sewage or the backflow phenomenon caused by uneven pressure inside and outside the cavity. By allowing air to enter the processing chamber 103, the internal negative pressure can be reduced, allowing the sewage to flow more smoothly into the release chamber 104 under the action of gravity, thereby improving the discharge efficiency.

[0041] As a further solution of the present invention, the top of the screw a200 extends into the medium cavity 101 and is connected to a rotating frame 600, and a plurality of rollers 601 are rotatably connected to the rotating frame 600. The bottom of the vibration plate 106 is connected to a concave-convex frame 602. A plurality of air ports a603 are provided on the side wall of the medium cavity 101, and a plurality of air ports b604 corresponding to the storage cavity 114 are provided on the vibration plate 106. A one-way valve mechanism for air intake is provided in the air port a603, and a one-way valve mechanism for air exhaust is provided in the air port b604. A spring l605 is provided between the vibration plate 106 and the medium cavity 101.

[0042] By setting the rotating frame 600, when the lead screw a200 rotates to drive the rotating frame 600 to move, the roller 601 contacts the concave-convex frame 602 and applies force periodically, and cooperates with the spring l605 to allow the vibration plate 106 to move up and down, generating vibration to the medium in the medium cavity 101. During the vibration process, the medium can overcome the accumulation resistance and enter the storage cavity 114 more evenly. In addition, during the up and down movement of the vibration plate 106, the one-way valve mechanism of the air port a603 allows external air to enter the medium cavity 101, while the one-way valve mechanism of the air port b604 releases air into the storage cavity 114, further promoting the dispersion and filling of the medium through the action of the air flow, and preventing the medium from agglomerating due to static electricity, adhesion or moisture, which affects the delivery effect. The one-way valve mechanism can be a spring check valve (spring check valve), a diaphragm check valve (flexible diaphragm valve), a duckbill valve (rubber check valve), a ball check valve, etc. This is a prior art and will not be described in detail here.

[0043] As a further solution of the present invention, the bottom of the release chamber 104 is connected to a drain pipe 112 , and a valve 113 is provided on the drain pipe 112 .

[0044] By setting the valve 113, the discharge of sewage in the release chamber 104 can be controlled to prevent sewage from flowing out at unscheduled times, thereby ensuring the controllability of the treatment process. After the treatment chamber 103 completes the sewage treatment, the drain pipe 112 can be used as a sewage discharge channel, and the opening and closing of the valve 113 can be regulated according to the progress of the sewage treatment and the operation requirements of the system. Specifically, the valve 113 can be an electric valve, a pneumatic valve or a manual valve to meet different automation control requirements.
