Description

Technical Field

[0001] This application relates to the technical field of sewage treatment, and particularly to a sewage treatment device for factories. Background Art

[0002] Sewage treatment in factories is an essential and important link in the industrial production process. Especially in industries such as metallurgy and chemical engineering, if sewage containing impurities such as iron oxide is directly discharged without effective treatment, it will cause serious pollution to the environment.

[0003] Currently, in the field of factory sewage treatment, a common treatment method is to add chemicals such as coagulants and flocculants to the sewage, and use the chemicals to react with the pollutants in the sewage to generate large particulate substances that are easy to separate, so as to achieve the separation of pollutants and water.

[0004] However, the traditional static chemical addition method is prone to uneven distribution of chemicals such as flocculants, resulting in a large difference in the concentration of the chemical solution at different depths in the sewage, making it difficult to achieve efficient and uniform mixing of the chemical solution and the sewage, and leading to poor sewage treatment effects.

[0005] In the above related technologies, there are defects in the uneven distribution of chemicals such as flocculants during sewage treatment. Summary of the Invention

[0006] In order to improve the problem of uneven distribution of chemicals such as flocculants during sewage treatment, this application provides a sewage treatment device for factories.

[0007] The sewage treatment device for factories provided by this application adopts the following technical solutions: A sewage treatment device for factories includes: a cylinder body with an open top, and the cylinder body is provided with an input port and an output port; a support column, the bottom of the support column is connected to the bottom of the cylinder body, and the axis of the support column coincides with the axis of the cylinder body; a chemical addition mechanism, the chemical addition mechanism includes a sleeve and several blades, the sleeve is movably sleeved on the support column, the blades are circumferentially distributed on the sleeve, the sleeve is provided with a first accommodation cavity, several of the blades are each provided with a second accommodation cavity, the first accommodation cavity is communicated with several of the second accommodation cavities, the first accommodation cavity and the second accommodation cavities form a chemical addition cavity for carrying the chemical solution, and the blades are provided with chemical solution outlets; a pushing mechanism, the pushing mechanism includes a first pusher and a second pusher, both the first pusher and the second pusher are movably sleeved on the support column, the first pusher is arranged above the sleeve for pushing the chemical addition mechanism from top to bottom, the second pusher is arranged below the sleeve for pushing the chemical addition mechanism from bottom to top, so that the chemical addition mechanism can move along the support column, and the blades can stir the sewage in the cylinder body.

[0008] By adopting the above technical solutions, the sewage treatment efficiency and quality of the factory can be effectively improved. Specifically: The cylinder body is used to hold sewage, so that the sewage can enter through the input port and discharge through the output port, so as to smoothly pass through the equipment for sewage treatment. At the same time, the top opening facilitates the operation of the dosing mechanism. The setting of the support column provides a guiding and supporting function for the dosing mechanism. The accommodating cavity is used to hold the liquid medicine, so that the liquid medicine can be discharged into the sewage through the medicine outlet for sewage treatment. The first pusher and the second pusher of the pushing mechanism are respectively located above and below the sleeve. By alternately pushing from top to bottom and from bottom to top, the dosing mechanism can move flexibly on the support column. On the one hand, the sewage is stirred through the blades, and on the other hand, the medicine can be evenly mixed at different depths in the sewage during the whole treatment process, optimizing the sewage treatment effect. Optionally, the dosing mechanism includes a medicine discharging component. A medicine discharging port is provided at the lower end of the sleeve. The medicine discharging component includes a first support plate, a first sealing block and a plurality of first elastic members. The first support plate is fixedly connected to the first accommodating cavity. One end of the first elastic member is connected to the first support plate, and the other end of the first elastic member is connected to the first sealing block. The first sealing block can block the medicine discharging port. A ball component is provided at the upper end of the second pusher. The ball component protrudes from the upper end surface of the second pusher. When the second pusher pushes the sleeve, the ball component pushes the first sealing block to open the medicine discharging port.

[0009] By adopting the above technical solutions, when the second pusher pushes the sleeve upward, the ball component will push the first sealing block, causing the medicine discharging port to open, thereby realizing the discharge of the liquid medicine. This design enables the dosing mechanism to add medicine during the rising process after moving to the bottom of the cylinder body, so that the liquid medicine can reach the bottom of the sewage, realizing the dosing of the bottom of the sewage, which helps to improve the uniformity of the liquid medicine distribution.

[0010] Optionally, the blades are inclined, so that the connecting line between the blades and the sleeve spirally winds around the outer periphery of the axis of the sleeve.

[0011] By adopting the above technical solutions, the inclined setting of the blades makes the connecting line between the blades and the sleeve spirally wind around the outer periphery of the axis of the sleeve, which can effectively reduce the resistance suffered by the blades during the stirring process and improve the stirring efficiency. At the same time, this design also enables the dosing mechanism to automatically rotate around the axis of the support column during the movement along the support column, further enhancing the uniformity of the mixing of the medicine and the sewage and the sewage treatment effect.

[0012] Optionally, the pushing mechanism includes a first connecting rope and a winding assembly. The winding assembly is mounted on the cylinder body. The first end of the first connecting rope is connected to the first pushing member, and the second end of the first connecting rope is wound around the winding assembly through a first reversing assembly. The first connecting rope can pull the first pushing member downward.

[0013] By adopting the above technical solution, the combined use of the first connecting rope and the winding assembly can effectively control the downward movement of the first pushing member, ensuring that the medicine adding mechanism accurately reaches the bottom of the cylinder body for medicine delivery. At the same time, this structural design simplifies the mechanical transmission system, reducing the complexity and maintenance cost of the equipment.

[0014] Optionally, the pushing mechanism includes a second connecting rope. The first end of the second connecting rope is connected to the second pushing member, and the second end of the second connecting rope is wound around the winding assembly through a second reversing assembly. The second connecting rope can pull the second pushing member upward.

[0015] By adopting the above technical solution, the second connecting rope can effectively pull the second pushing member upward, ensuring that the medicine adding mechanism can smoothly move upward along the support column, so that the liquid medicine in the medicine adding cavity is evenly distributed in the sewage, improving the sewage treatment effect.

[0016] Optionally, the winding assembly includes a driving member and a winding shaft. The cylinder body is provided with a support platform. The driving member is mounted on the support platform. The output end of the driving member is drivingly connected to one end of the winding shaft. The other end of the winding shaft is rotatably connected to the side wall of the cylinder body. The winding shaft is used for winding the first connecting rope and the second connecting rope.

[0017] By adopting the above technical solution, the driving member can accurately control the rotation of the winding shaft, thereby realizing the synchronous or asynchronous pulling of the first connecting rope and the second connecting rope. This design not only improves the stability and accuracy of the up and down movement of the medicine adding mechanism, but also effectively reduces the need for manual operation, improving the automation degree of the equipment. At the same time, the support platform provides a stable installation foundation for the driving member, ensuring the operation reliability of the entire system.

[0018] Optionally, the pushing mechanism includes a connecting sleeve. The connecting sleeve is sleeved on the outer periphery of the support column. The two ends of the connecting sleeve are respectively connected to the first pushing member and the second pushing member. The sleeve is sleeved on the outer periphery of the connecting sleeve. Both the first connecting rope and the second connecting rope pass through the sleeve.

[0019] By adopting the above technical solution, the setting of the connecting sleeve makes the linkage between the first pushing member and the second pushing member more stable and reliable, contributing to the realization of the pushing effect on the medicine adding mechanism.

[0020] Optionally, the pushing mechanism includes a first horn-shaped cylinder and a second horn-shaped cylinder, both of which are horn-shaped. The small end with a smaller diameter of the first horn-shaped cylinder is connected to one end of the first pushing member away from the sleeve. The large end with a larger diameter of the first horn-shaped cylinder extends away from the sleeve. The first horn-shaped cylinder is used to limit the position of the second connecting rope and accelerate the flow rate of sewage from the large end to the small end of the first horn-shaped cylinder, so as to impact the first pushing member. The small end with a smaller diameter of the second horn-shaped cylinder is connected to one end of the second pushing member away from the sleeve. The large end with a larger diameter of the first horn-shaped cylinder extends away from the sleeve. The second horn-shaped cylinder is used to limit the position of the first connecting rope and accelerate the flow rate of sewage from the large end to the small end of the second horn-shaped cylinder (48), so as to impact the second pushing member and reduce the residence time of impurities in the pushing mechanism.

[0021] By adopting the above technical solution, the design of the first horn-shaped cylinder and the second horn-shaped cylinder can effectively limit the positions of the second connecting rope and the first connecting rope, preventing them from deviating too much during use. At the same time, the structural design of the horn-shaped cylinder gradually narrowing from the large end to the small end can significantly accelerate the speed of sewage flowing through, thereby generating a greater impact force on the first pushing member and the second pushing member, ensuring that they can complete the reciprocating motion up and down more stably and efficiently. In addition, this accelerated flow can effectively reduce the residence time of impurities inside the pushing mechanism, reduce the risk of blockage, and improve the working efficiency and reliability of the entire sewage treatment equipment.

[0022] Optionally, the blade is provided with a medicine adding port, and the medicine adding mechanism is provided with a medicine adding component. The medicine adding component includes a second support plate, a second sealing block and a second elastic member. The second support plate is fixedly arranged in the second accommodating cavity. One end of the second elastic member is connected to the second support plate, and the other end of the second elastic member is connected to the second sealing block. The second sealing block can block the medicine adding port.

[0023] By adopting the above technical solution, when medicine needs to be added, press the second sealing block, and the medicine can be sent into the second accommodating cavity from the medicine adding port. After the medicine adding is completed, release the second sealing block. At this time, the second sealing block will block the medicine adding port under the action of the second elastic member to prevent medicine leakage.

[0024] Optionally, a maintenance platform is provided around the outer circumference of the cylinder body, and the maintenance platform is arranged above the input port.

[0025] By adopting the above technical solution, the setting of the maintenance platform facilitates the operators to carry out inspection and maintenance work during the operation of the equipment, improving the work efficiency. Setting the maintenance platform above the input port enables the operators to more conveniently approach the input port position, facilitating the observation and cleaning of the water inlet situation to ensure the normal operation of the equipment; meanwhile, the maintenance platform facilitates the replenishment of the liquid medicine in the dosing mechanism, reducing the operation difficulty.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the dynamic dosing of the dosing mechanism and the stirring function of the blades, the uniform distribution of the liquid medicine in the sewage is achieved, increasing the contact probability between the liquid medicine and the impurities in the sewage, thus significantly improving the sewage treatment effect; 2. The design of the support column enables the dosing mechanism to move up and down in the cylinder. At the same time, the inclined setting of the blades reduces the movement resistance, enhancing the stirring efficiency and effectively avoiding the problem of uneven distribution of liquid medicines such as flocculants caused by the traditional static dosing method; 3. The first pusher and the second pusher of the pushing mechanism are used in cooperation to ensure that the dosing mechanism can move stably along the support column, further ensuring the uniform release of the liquid medicine and the full mixing of the sewage, and solving the problem of the separation of high-density impurities such as iron oxide from water.

[0037] The following will further describe the present application in detail with reference to the attached Figure 1 - attached Figure 9 For the present application, a further detailed description is made.

Moreover, in the description of this embodiment, the orientation or positional relationship terms such as "above", "below", "left" and "right" are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application. Without contrary description, the orientation terms such as "inside, outside" used in the present application refer to the outline of the corresponding component itself.

[0039] As Figure 1 、 Figure 2 and Figure 3 shown, the embodiment of the present application discloses a factory sewage treatment device (hereinafter simply referred to as "device"). The device includes a cylinder body 1, a support column 2, a chemical dosing mechanism 3 and a pushing mechanism 4, which are used to uniformly distribute liquid medicines such as flocculants in the sewage in the cylinder body 1 and optimize the separation effect of impurities such as iron oxide in the sewage.

[0040] As shown in Figure 1 , Figure 3 and Figure 4 , the cylinder body 1 is used to carry sewage. The cylinder body 1 is provided with an input port 11 and an output port 12, so that sewage can enter through the input port 11 and be discharged through the output port 12 after being processed. The top of the cylinder body 1 is open, which is convenient for adding medicine to the medicine adding mechanism 3. The bottom of the support column 2 is connected to the bottom of the cylinder body 1, and the axis of the support column 2 coincides with the axis of the cylinder body 1. The support column 2 provides a guiding and supporting function for the medicine adding mechanism 3. The medicine adding mechanism 3 includes a sleeve 31 and a plurality of blades 32. The sleeve 31 is movably sleeved on the support column 2, and the blades 32 are circumferentially distributed on the sleeve 31. The sleeve 31 is provided with a first accommodating cavity 311, and a plurality of blades 32 are each provided with a second accommodating cavity 321. The first accommodating cavity 311 communicates with the plurality of second accommodating cavities 321. The first accommodating cavity 311 and the second accommodating cavities 321 form a medicine adding cavity, which is used to carry the liquid medicine. The blade 32 is provided with a medicine outlet 322, so that the liquid medicine can be initially discharged into the sewage through the medicine outlet 322 for sewage treatment. In this embodiment, the medicine outlet 322 is inclined upward, so that the liquid medicine can initially flow out and the discharge speed of the liquid medicine can be slowed down to a certain extent, so that the liquid medicine can continue to be discharged after reaching the bottom of the cylinder body 1, alleviating the problem that the liquid medicine is concentrated on the upper layer of the sewage due to the too fast output speed of the medicine outlet 322. At the same time, according to actual needs, the diameter of the medicine outlet 322 is made smaller, so that a large amount of liquid medicine still remains in the medicine adding cavity when it moves to the bottom of the cylinder body 1.

[0041] As shown in Figure 3 , Figure 4 and Figure 5 , the pushing mechanism 4 includes a first pusher 41 and a second pusher 42. Both the first pusher 41 and the second pusher 42 are movably sleeved on the support column 2. Among them, the first pusher 41 is arranged above the sleeve 31 and is used to push the medicine adding mechanism 3 from top to bottom; the second pusher 42 is arranged below the sleeve 31 and is used to push the medicine adding mechanism 3 from bottom to top. The pushing mechanism 4 enables the medicine adding mechanism 3 to move along the support column 2, and the blade 32 can stir the sewage in the cylinder body 1 to improve the mixing degree. The first pusher 41 and the second pusher 42 of the pushing mechanism 4 are respectively located above and below the sleeve 31. By alternately pushing from top to bottom and from bottom to top, the medicine adding mechanism 3 can move flexibly on the support column 2. On the one hand, the sewage can be stirred through the blade 32, and on the other hand, the medicine can be evenly mixed at different depths in the sewage during the whole treatment process, optimizing the sewage treatment effect.

[0042] As shown in Figure 3 , Figure 4 and Figure 5As shown, optionally, the blade 32 is inclined such that the connecting line between the blade 32 and the sleeve 31 spirally winds around the outer periphery of the axis of the sleeve 31. The inclined setting of the blade 32 enables the connecting line between the blade 32 and the sleeve 31 to spirally wind around the outer periphery of the axis of the sleeve 31, which can effectively reduce the resistance suffered by the blade 32 during the stirring process and improve the stirring efficiency. At the same time, this design also enables the chemical dosing mechanism 3 to automatically rotate around the axis of the support column 2 under the pushing action of the sewage during the movement along the support column 2, further enhancing the uniformity of the mixing of the drug and the sewage and the sewage treatment effect.

[0043] As Figure 3 , Figure 6 and Figure 7 shown, optionally, the pushing mechanism 4 includes a first connecting rope 43 and a winding assembly 44. The winding assembly 44 is mounted on the cylinder body 1. The first end of the first connecting rope 43 is connected to the first pusher 41, and the second end of the first connecting rope 43 is wound around the winding assembly 44 through a first commutation assembly. The first connecting rope 43 can pull the first pusher 41 downward. The combined use of the first connecting rope 43 and the winding assembly 44 can effectively control the downward movement of the first pusher 41 to ensure that the chemical dosing mechanism 3 accurately reaches the bottom of the cylinder body 1 for drug delivery. At the same time, this structural design simplifies the mechanical transmission system and reduces the complexity and maintenance cost of the equipment. A commutation groove is provided on the side wall of the cylinder body 1 for mounting the first commutation assembly and enabling the first connecting rope 43 to move in the commutation groove.

[0044] As Figure 3 , Figure 6 and Figure 7 shown, optionally, the pushing mechanism 4 includes a second connecting rope 45. The first end of the second connecting rope 45 is connected to the second pusher 42, and the second end of the second connecting rope 45 is wound around the winding assembly 44 through a second commutation assembly. The second connecting rope 45 can effectively pull the second pusher 42 upward to ensure that the chemical dosing mechanism 3 can smoothly move upward along the support column 2, so that the liquid medicine in the chemical dosing cavity is evenly distributed in the sewage and the sewage treatment effect is improved. In this embodiment, both the first commutation assembly and the second commutation assembly include a plurality of fixed pulleys, so that the first connecting rope 43 and the second connecting rope 45 can extend from the chemical dosing mechanism 3 to the winding assembly 44.

[0045] Optionally, the winding assembly 44 includes a driving member 441 and a winding shaft 442. The cylinder body 1 is provided with a support platform 13, and the driving member 441 is mounted on the support platform 13. The support platform 13 provides a stable installation foundation for the driving member 441, ensuring the operation reliability of the entire system. The output end of the driving member 441 is drivingly connected to one end of the winding shaft 442, and the other end of the winding shaft 442 is rotatably connected to the side wall of the cylinder body 1. The winding shaft 442 is used for winding the first connecting rope 43 and the second connecting rope 45. The driving member 441 can be a motor, and the driving member 441 can precisely control the rotation of the winding shaft 442, thereby realizing the synchronous or asynchronous pulling of the first connecting rope 43 and the second connecting rope 45. This design not only improves the stability and accuracy of the vertical movement of the chemical dosing mechanism 3, but also effectively reduces the need for manual operation and improves the automation level of the equipment. In this embodiment, there is a set of winding assemblies 44. The second ends of the first connecting rope 43 and the second connecting rope 45 are connected and wound around the winding shaft 442. The outer periphery of the winding shaft 442 is provided with a rough layer. The second ends of the first connecting rope 43 and the second connecting rope 45 can both be flexible ropes made of rough materials such as hemp ropes, so that there is sufficient friction between both the first connecting rope 43 and the second connecting rope 45 and the winding shaft 442, and there is no relative sliding between the first connecting rope 43 and the second connecting rope 45 and the winding shaft 442. Thus, through the rotation of the winding shaft 442, the first pusher 41 and the second pusher 42 can be lifted or lowered synchronously, reducing the risk of interference caused by the reverse pulling of the first connecting rope 43 and the second connecting rope 45. In other embodiments, two sets of winding assemblies 44 can be provided, and the two sets of winding assemblies 44 respectively correspond to the first pusher 41 and the second pusher 42.

[0046] Such as Figure 3 , Figure 4 and Figure 5As shown, optionally, the pushing mechanism 4 includes a connecting sleeve 46 sleeved on the outer periphery of the support column 2. The two ends of the connecting sleeve 46 are respectively connected to the first pushing member 41 and the second pushing member 42. The sleeve 31 is sleeved on the outer periphery of the connecting sleeve 46. Both the first connecting rope 43 and the second connecting rope 45 pass through the sleeve 31. The setting of the connecting sleeve 46 can improve the integrity of the pushing mechanism 4, so as to improve the reliability during the up-and-down movement, reduce the abrasion of the rope caused by relative movement, and improve the service life of the rope. The first ends of both the first connecting rope 43 and the second connecting rope 45 can be made of steel wire ropes. The pulling force of the first connecting rope 43 on the first pushing member 41 is set at a first angle with the axis of the support column 2, and the pulling force of the second connecting rope 45 on the second pushing member 42 is set at a second angle with the support column 2. The setting of the connecting sleeve 46 makes the linkage between the first pushing member 41 and the second pushing member 42 more stable and reliable. To improve the pulling reliability, two connecting heads can be provided at the first end of the first connecting rope 43, and two connecting heads can be provided at the first end of the second connecting rope 45 to increase the connection points with the first pushing member 41 and the second pushing member 42, and the two connecting heads on the same rope are symmetrically arranged. The pulling force of the first connecting rope 43 on the first pushing member 41 is set at a first angle with the axis of the support column 2, and the pulling force of the second connecting rope 45 on the second pushing member 42 is set at a second angle with the support column 2. Both the first angle and the second angle change periodically, making the dosing mechanism 3 as a whole in an inclined state, which helps to make the blades 32 rotate due to uneven force, thereby improving the stirring degree.

[0047] As Figure 3 , Figure 4 and Figure 5 shown, optionally, the pushing mechanism 4 includes a first horn tube 47 and a second horn tube 48 both in a horn shape. The small end with a smaller diameter of the first horn tube 47 is connected to the end of the first pushing member 41 away from the sleeve 31, and the large end with a larger diameter of the first horn tube 47 extends away from the sleeve 31. The first horn tube 47 is used to limit the second connecting rope 45 and accelerate the flow rate of the sewage flowing from the large end to the small end of the first horn tube 47, so as to achieve an impact on the first pushing member 41. The small end with a smaller diameter of the second horn tube 48 is connected to the end of the second pushing member 42 away from the sleeve 31, and the large end with a larger diameter of the first horn tube 47 extends away from the sleeve 31. The second horn tube 48 is used to limit the first connecting rope 43 and accelerate the flow rate of the sewage flowing from the large end to the small end of the second horn tube 48, so as to achieve an impact on the second pushing member 42 and reduce the residence time of impurities in the pushing mechanism 4.

[0048] The designs of the first horn 47 and the second horn 48 can effectively limit the positions of the first connecting rope 43 and the second connecting rope 45, preventing excessive deviation during use. At the same time, the structural design of the horn gradually narrowing from the large end to the small end can significantly accelerate the flow rate of the sewage when it passes through, thereby generating a greater impact force acting on the first pusher 41 and the second pusher 42, ensuring that they can complete the reciprocating up and down movement more stably and efficiently. In addition, this accelerated flow can effectively reduce the residence time of impurities inside the pushing mechanism 4, reduce the risk of blockage, and improve the working efficiency and reliability of the entire sewage treatment equipment.

[0049] As Figure 3 , Figure 4 and Figure 8 shown, optionally, the dosing mechanism 3 includes a medicine discharging assembly 33, and a medicine discharging port is provided at the lower end of the sleeve 31. The medicine discharging assembly 33 includes a first support plate 331, a first sealing block 332 and a plurality of first elastic members 333. The first support plate 331 is fixedly connected inside the first accommodating cavity 311. One end of the first elastic member 333 is connected to the first support plate 331, and the other end of the first elastic member 333 is connected to the first sealing block 332. The first sealing block 332 can block the medicine discharging port. A ball component 421 is provided at the upper end of the second pusher 42. The ball component 421 protrudes from the upper end surface of the second pusher 42. When the second pusher 42 pushes the sleeve 31, the ball component 421 pushes the first sealing block 332 to open the medicine discharging port.

[0050] When the second pusher 42 pushes the sleeve 31 upward, the ball component 421 will push the first sealing block 332 to open the medicine discharging port, thereby realizing the discharge of the liquid medicine. This design enables the dosing mechanism 3 to dose during the upward movement after moving to the bottom of the cylinder body 1, so that the liquid medicine can reach the bottom of the sewage, realizing dosing at the bottom of the sewage, which helps to improve the uniformity of the liquid medicine distribution. The medicine discharging port is used for further discharging the medicine based on the medicine outlet 322, and the flow rate of the medicine discharging port is greater than that of the medicine outlet 322. The ball component 421 includes a mounting groove provided on the upper end surface of the second pusher 42 and a plurality of balls. The balls roll in the mounting groove to reduce the friction on the dosing mechanism 3 and enable the dosing mechanism 3 to rotate freely.

[0051] As Figure 3 , Figure 4 and Figure 9As shown, optionally, the blade 32 is provided with a medicine adding port, and the medicine adding mechanism 3 is provided with a medicine adding component 34. Since sewage will enter the medicine adding cavity during the medicine discharging process, before adding medicine again, clean water can be poured into the medicine adding cavity through the medicine adding port to improve the cleanliness of the medicine adding cavity. The medicine adding component 34 includes a second support plate 341, a second sealing block 342 and a second elastic member 343. The second support plate 341 is fixedly arranged in the second accommodating cavity 321. One end of the second elastic member 343 is connected to the second support plate 341, and the other end of the second elastic member 343 is connected to the second sealing block 342. The second sealing block 342 can block the medicine adding port. When medicine needs to be added, press the second sealing block 342, and the medicine can be sent into the second accommodating cavity 321 through the medicine adding port. After the medicine adding is completed, release the second sealing block 342. At this time, the second sealing block 342 will block the medicine adding port under the action of the second elastic member 343 to prevent medicine leakage. Both the first elastic member 333 and the second elastic member 343 can be springs.

[0052] As Figure 3 As shown, optionally, a maintenance platform 14 is provided around the outer circumference of the cylinder body 1. The maintenance platform 14 is arranged above the input port 11, reducing the interference of operators on the sewage input and improving safety. The setting of the maintenance platform 14 facilitates the operators to carry out inspection and maintenance work during the operation of the equipment, improving work efficiency.
