Description

Technical Field

[0001] This invention relates to the field of biogas slurry treatment technology, specifically to a controllable biogas slurry treatment device for aquaculture and its application. Background Technology

[0002] Biogas slurry not only contains abundant macronutrients such as nitrogen, phosphorus, and potassium, as well as micronutrients such as zinc, but also contains 17 kinds of amino acids and active enzymes. Current biogas slurry treatment is divided into two directions: one is mainly for resource utilization, which mainly uses simple anaerobic fermentation treatment to meet agricultural irrigation standards; the other is mainly for compliant discharge, which complies with the "Pollutant Discharge Standard for Livestock and Poultry Breeding Industry".

[0003] However, existing biogas slurry equipment suffers from difficulties in treating aquaculture biogas slurry, high costs, complex facilities and processes, large land occupation, and is often limited by the process, with effluent indicators restricted to a specific range and unable to be adjusted according to actual needs. For example: 1) Processes that favor resource utilization are simple to treat but require maximum retention of nutrients in the aquaculture biogas slurry. The continuous output of biogas slurry cannot be absorbed by the surrounding land, often requiring a large amount of land for temporary storage; 2) Processes that favor compliance with discharge standards are costly and require large investments, and all valuable nutrients are removed, which contradicts the principles of green circular economy and resource utilization.

[0004] Meanwhile, the treatment effect of aquaculture biogas slurry is determined by factors such as the dosage of chemicals, the degree of chemical mixing, and the reaction time of chemicals. Therefore, there is a need for a new type of aquaculture biogas slurry treatment equipment that can meet the needs of adjusting the treatment scenarios and improve the treatment effect of aquaculture biogas slurry. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a controllable aquaculture biogas slurry treatment device and its application.

[0006] The technical solution of the present invention is: a controllable aquaculture biogas slurry treatment device, comprising a box body, and a mixing chamber for mixing and reacting the agent with the aquaculture biogas slurry, a sedimentation chamber for settling the aquaculture biogas slurry after mixing and reacting, an ozone treatment chamber for treating the aquaculture biogas slurry with ozone, and a filter chamber for filtering and removing impurities from the aquaculture biogas slurry, which are separated from left to right by vertically arranged partitions.

[0007] The mixing chamber is equipped with multiple mixers. An inlet is located on one side of the chamber, and a dosing pipe is mounted on the side wall near the inlet. This dosing pipe is equipped with a controlled-release device for controlling the mixing and addition of chemicals. An outlet, connected to a sedimentation chamber, is located on a partition on the other side of the mixing chamber. Furthermore, multiple vertically staggered baffles are arranged within the mixing chamber between the inlet and outlet, creating an S-shaped flow path.

[0008] The sedimentation chamber and the ozone treatment chamber are connected by guide pipes, and the ozone treatment chamber and the filtration chamber are connected by guide pipes. The filter chamber is provided with a liquid outlet and a slag outlet on one side of the box.

[0009] Furthermore, the controlled-release drug device is divided into an electric-driven controlled-release drug device and a water-driven controlled-release drug device according to the power drive method. The electric-driven controlled-release drug device includes a controlled-release drug mechanism and a drive motor connected to the controlled-release drug mechanism via an output shaft. The water-driven controlled-release drug device includes a controlled-release drug mechanism and a water wheel connected to the controlled-release drug mechanism via a shaft.

[0010] Note: The controlled-release device of the present invention provides two driving methods. It can use a drive motor to drive the controlled-release mechanism, or it can use the biogas slurry to drive a water wheel to drive the controlled-release mechanism when the biogas slurry is injected into the dosing pipe, thus making it more energy-saving and environmentally friendly.

[0011] Furthermore, the controlled-release mechanism includes a controlled-release turntable, a controlled-release gear, a drug release bladder, and a drug cartridge;

[0012] The controlled-release turntable is fixedly connected to the turbine shaft and is also rotatably connected to the dosing pipe. The turntable has an annular flange with arc-shaped tooth segments formed by several tooth grooves. The controlled-release gear has a toothless slow-stop section. The controlled-release gear is perpendicular to the turntable and is rotatably connected to a carrier plate on the side wall of the tank via a rotating shaft. The shaft of the controlled-release gear extends into the internal cavity of the carrier plate and has a cam. A cam frame, fitted onto the cam and used for reciprocating motion by rotating the cam, is slidably mounted in the internal cavity of the carrier plate. A sealing plate is provided on one side of the baffle, and the sealing plate is slidably and sealingly connected to a sink in the side wall of the baffle. The sealing plate and the sink are connected by several springs. A connecting rope is provided on the cam frame, one end of which passes sequentially through the carrier plate, the tank, and the baffle and connects to the sealing plate.

[0013] A lever is provided on one side of the end face of the control gear in the slow-stop section, and a paddle is provided on the control turntable for moving the lever to make the teeth of the control gear mesh with the arc-shaped tooth segment. The paddle is rotatably connected to the support seat on the control turntable via a torsion spring shaft.

[0014] The drug-releasing liquid capsules are provided in multiple locations, each corresponding to a toothed groove and positioned within the groove. A liquid tube is located at the bottom of each drug-releasing liquid capsule, passing sequentially through an annular flange and a controlled-release disc. From top to bottom, the liquid tube consists of a first rigid tube located at the annular flange and the controlled-release disc, and a second rigid tube extending from the controlled-release disc.

[0015] The drug cartridge is detachably mounted on a carrier plate located on one side of the controlled-release gear, and the drug cartridge extends into the dosing tube and is located below the controlled-release turntable.

[0016] Explanation: The above-mentioned slow-release mechanism allows for the intermittent and controlled addition of medication to the aquaculture slurry, thereby improving the mixing and reaction effect between the slurry and medication in the mixing chamber. This structure also enables automatic medication administration and replenishment, allowing for multiple small additions. Compared to gravity-based medication addition, this method offers higher dosage control precision, enabling accurate and precise multiple controlled additions, saving processing costs, and further improving medication dispersion. This avoids problems such as slow dispersion and increased processing costs caused by large-scale localized addition.

[0017] Meanwhile, through the cooperation of components such as cams and cam frames with the drug slow-release mechanism, since the controlled-release gear only rotates within the arc-shaped tooth section of the controlled-release turntable, the opening interval of the sealing plate can be significantly extended and controlled compared to continuous meshing transmission. This allows the aquaculture biogas slurry and the drug to be stirred and retained for a longer time, and this function can be achieved without the need for an additional drive motor.

[0018] Furthermore, a groove is provided on the end face of one side wall of the medicine box, and a bevel gear and a first pulley are rotatably mounted in the groove. A bevel gear ring for meshing and driving with the bevel gear is provided on the bottom surface of the controlled-release turntable. The bevel gear and the first pulley rotate coaxially via a rotating shaft.

[0019] Several stirring shafts are arranged horizontally inside the medicine box. One end of the stirring shaft passes through the cavity of the inner wall of the medicine box and is equipped with a second pulley. Each of the second pulleys and the first pulley are connected by a transmission belt. The stirring shaft is rotatably and sealed to the inner wall of the medicine box.

[0020] Explanation: The above structure enables the controlled-release mechanism to automatically administer and replenish medication, while also preventing the mixed medication in the medication box from settling due to prolonged standing. Without the need for additional drive mechanisms, the mixed medication in the medication box can be stirred to prevent sedimentation.

[0021] Furthermore, the outer wall of the medicine box is provided with several air bladders, and the bottom surface of the controlled-release turntable is provided with an arc-shaped plate for pushing the air bladders. The air bladders are rotatably and sealed to one end of the stirring shaft through pipes.

[0022] The stirring shaft is hollow inside and has multiple stirring blades on it, and multiple disturbance plates connected to the inside of the stirring shaft through air bladder rods are also provided on the stirring shaft.

[0023] Explanation: The above structure, based on the anti-sedimentation design of the medicine box, utilizes components such as airbags, airbag rods, and disturbance plates to drive the disturbance plates to agitate the mixture during stirring by the stirring shaft. This enhances the stirring effect of the stirring shaft on the mixed medicine in the medicine box, preventing sedimentation and thus avoiding affecting the effectiveness of the medicine.

[0024] Furthermore, the medicine box is divided into a drug delivery compartment and a refill compartment. The refill compartment is located above the drug delivery compartment. A drug delivery tube is vertically arranged inside the refill compartment. The lower end of the drug delivery tube passes through the refill compartment and extends into the drug delivery compartment. A drug delivery port communicating with its lower end is provided on the middle side wall of the drug delivery tube. The upper end of the drug delivery tube passes through the refill compartment and is provided with a pressure tablet. A spring is sleeved on the drug delivery tube located between the pressure tablet and the refill compartment. A swing plate is provided on the refill compartment on one side of the drug delivery tube. The swing plate is rotatably connected to a bracket provided on the refill compartment. One end of the swing plate contacts the pressure tablet, and the other end of the swing plate extends to the control-release gear and is located above the lever.

[0025] Explanation: Since the liquid level in the drug delivery chamber drops significantly after each replenishment of the drug release sac, while a deeper drug delivery box design can slow down the liquid level consumption per dose, it does not effectively solve this problem. Furthermore, a deeper drug delivery box design not only affects the operation of the water impeller below, but also easily causes the drug inside the box to splash when the liquid pipe is bent and restored. Therefore, based on the controlled-release drug mechanism, we have set up a replenishment chamber that can automatically replenish the drug delivery chamber. This design effectively solves this problem.

[0026] Furthermore, the inlet of the guide pipe between the sedimentation chamber and the ozone treatment chamber is slidably connected to the partition plate, and the partition plate is equipped with a lifting motor for adjusting the height of the inlet of the guide pipe.

[0027] Note: By making the guide pipe between the sedimentation tank and the ozone treatment tank have a liftable function, the controllable aquaculture biogas slurry treatment equipment of the present invention can cope with various slag discharge methods of the sedimentation tank, such as floating slag discharge or sedimentation slag discharge.

[0028] Furthermore, the baffle is provided with interlaced arc-shaped spoilers with the curved side opposite to the flow direction of the S-shaped flow path. The arc-shaped spoilers are hinged to the baffle via a torsion spring shaft, and the baffle is provided with a baffle strip for limiting the swing angle of the arc-shaped spoilers.

[0029] Explanation: By installing arc-shaped baffles on the baffle plate, the residence time of the biogas slurry in the mixing chamber can be further increased. At the same time, with the effect of the torsion spring shaft, it can adaptively adjust according to the water flow. When the water flow rate is too fast, the arc-shaped baffles overcome the obstruction effect of the increased torque of the torsion spring shaft on the water flow, thereby ensuring that the biogas slurry can fully react with the agents in the mixing chamber while ensuring efficient treatment.

[0030] Furthermore, the box is covered with a cover, and the bottom of the box is equipped with casters.

[0031] Note: By placing the device in a movable housing, it can be easily moved as a whole and used in multiple scenarios. At the same time, the core components of the device can be covered to prevent damage caused by dust, collisions, etc., thereby improving the service life of the device.

[0032] The present invention also provides an application of a controllable aquaculture biogas slurry treatment device. Based on the above-mentioned controllable aquaculture biogas slurry treatment device, the controllable aquaculture biogas slurry treatment device is used for the treatment and discharge of aquaculture biogas slurry, or for the production of liquid fertilizer from aquaculture biogas slurry.

[0033] Description: By using the controllable aquaculture biogas slurry treatment equipment of the present invention, the mixing chamber, sedimentation chamber, ozone treatment chamber and filtration chamber are integrated in sequence, and different treatment agents are added according to the treatment needs using a controlled release device. Thus, the controllable aquaculture biogas slurry treatment equipment can be used for the treatment and discharge of aquaculture biogas slurry or for the production of liquid fertilizer from aquaculture biogas slurry. It has the advantages of being easy to use and operate.

[0034] The beneficial effects of this invention are:

[0035] (1) The controllable aquaculture biogas slurry treatment equipment of the present invention can achieve the controllable gradient treatment target from the nutrient output of aquaculture biogas slurry to the reuse of clean water through the controllable treatment intensity design. During the fertilization season, it can provide a large amount of nutrient-rich liquid fertilizer for agricultural planting, and during the non-production season, it can provide clean water for aquaculture enterprises to reuse, which can maximize the rational and full disposal of wastewater.

[0036] (2) The controllable aquaculture biogas slurry treatment equipment of the present invention, through the structural design of the drug slow-release mechanism, enables the intermittent and controlled addition of drugs to the aquaculture biogas slurry, thereby improving the mixing and reaction effect of the aquaculture biogas slurry and the drug that subsequently enter the mixing chamber. At the same time, it enables automatic drug administration and replenishment, and realizes multiple drug additions, thereby further improving the drug dispersion effect, avoiding the problem of slow drug diffusion and increased treatment costs caused by large local additions, and significantly increasing the residence time of aquaculture biogas slurry in the mixing chamber, without the need to add electric drive equipment such as motors.

[0037] (3) The controllable aquaculture biogas slurry treatment equipment of the present invention integrates a mixing chamber, a sedimentation chamber, an ozone treatment chamber and a filtration chamber in sequence, and uses a controlled-release device to add different treatment agents according to the treatment needs, so that the controllable aquaculture biogas slurry treatment equipment can be used for the treatment and discharge of aquaculture biogas slurry, and can also be used to manufacture liquid fertilizer from aquaculture biogas slurry.

Detailed Implementation

[0057] The present invention will now be described in more detail with reference to specific embodiments, so as to better demonstrate the advantages of the present invention.

[0058] Example 1:

[0059] like Figures 1-5 As shown, a controllable aquaculture biogas slurry treatment device includes a housing 1, and a mixing chamber 2 for mixing and reacting the agent with the aquaculture biogas slurry, a sedimentation chamber 3 for settling the aquaculture biogas slurry after mixing and reacting, an ozone treatment chamber 4 for ozone treatment of the aquaculture biogas slurry, and a filter chamber 5 for filtering and removing impurities from the aquaculture biogas slurry, which are separated from left to right by vertically arranged partitions 11. The inlet of the guide pipe between the sedimentation chamber 3 and the ozone treatment chamber 4 is slidably connected to the partitions 11, and the partitions 11 are equipped with a lifting motor for adjusting the height of the guide pipe inlet; it is understood that the lifting motor refers to a commercially available lifting motor.

[0060] The mixing chamber 2 is equipped with three mixers. A water inlet 21 is provided on one side of the box body of the mixing chamber 2. A dosing pipe 6 is provided on the side wall of the box body 1 located at the water inlet 21. The dosing pipe 6 is equipped with a controlled-release device for controlling the mixing and addition of the reagents. A water outlet 22 is provided on the partition 11 on the other side of the mixing chamber 2, which is connected to the sedimentation chamber 3. Two baffles 23 are vertically staggered in the mixing chamber 2 between the water inlet 21 and the water outlet 22, so that the mixing chamber forms an S-shaped flow path. A guide pipe is provided between the sedimentation chamber 3 and the ozone treatment chamber 4, and between the ozone treatment chamber 4 and the filter chamber 5. A drain outlet 51 and a slag outlet 52 are provided on the box body 1 on one side of the filter chamber 5. It can be understood that the mixer refers to a commercially available mixer, and the three mixers are respectively set in the three compartments.

[0061] The controlled-release device is an electrically driven controlled-release device, which includes a controlled-release mechanism 7 and a drive motor 8 connected to the controlled-release mechanism 7 via an output shaft; it is understood that the drive motor 8 refers to a commercially available motor.

[0062] like Figure 5 , Figures 9-13 As shown, the controlled-release mechanism 7 includes a controlled-release turntable 71, a controlled-release gear 72, a drug release bladder 73, and a drug container 74. The controlled-release turntable 71 is fixedly connected to the output shaft of the drive motor 8, and is also rotatably connected to the drug delivery tube 6. The controlled-release turntable 71 has an annular flange 711, and the annular flange 711 has an arc-shaped tooth segment 712 composed of several tooth grooves. The controlled-release gear 72 has a toothless slow-stop section 721. The controlled-release gear 72 is perpendicular to the controlled-release turntable 71, and the controlled-release gear 72 is connected to the side wall of the housing 1 via a rotating shaft. The carrier plate 75 is rotatably connected, and the shaft of the control gear 72 extends into the internal cavity of the carrier plate 75 and is provided with a cam 77. The internal cavity of the carrier plate 75 is slidably provided with a cam frame 771, which is sleeved on the cam 77 and is used for reciprocating motion by rotating the cam 77. A sealing plate 24 is provided on one side of the baffle 23. The sealing plate 24 is slidably and sealingly connected to the groove on the side wall of the baffle 23, and the sealing plate 24 and the groove are connected by several springs. A connecting rope 772 is provided on the cam frame 771. One end of the connecting rope 772 passes through the carrier plate 75, the box 1, and the baffle 23 in sequence and is connected to the sealing plate 24.

[0063] The release gear 72 in the slow-stop section 721 has a lever 722 on one side of its end face, and the release control turntable 71 has a paddle 713 for moving the lever 722 to engage the teeth of the release gear 72 with the arc-shaped tooth segment 712. The paddle 713 is rotatably connected to the support base 714 on the release control turntable 71 via a torsion spring shaft.

[0064] The drug-releasing liquid capsule 73 is provided in eight parts, each corresponding to one of the toothed grooves and disposed in the groove. The bottom of the drug-releasing liquid capsule 73 is provided with a liquid tube 76, which passes through the annular flange 711 and the controlled-release rotating disk 71 in sequence. The liquid tube 76 is composed of a first rigid tube 761 located in the annular flange 711 and the controlled-release rotating disk 71, a flexible tube 762 extending out of the controlled-release rotating disk 71, and a second rigid tube 763 from top to bottom.

[0065] The drug box 74 is detachably mounted on the carrier plate 75 located on one side of the controlled-release gear 72, and the drug box 74 extends into the dosing tube 6 and is located below the controlled-release turntable 71.

[0066] The box 1 is covered with a cover 10, and the bottom surface of the box 1 is provided with six sets of casters, including four sets of casters located at the four corners of the bottom surface of the box 1 and two sets of casters located at the center of the bottom surface of the box 1. It can be understood that the casters are selected from commercially available products.

[0067] It is understood that the agents mentioned above are commercially available agents used to treat aquaculture biogas slurry or nutrients used to supplement the nitrogen, phosphorus and potassium content of aquaculture biogas slurry, etc., and are not limited here, such as commercially available PAC flocculants.

[0068] The working method of the above-mentioned controllable aquaculture biogas slurry treatment equipment is as follows:

[0069] The biogas slurry is injected through the dosing pipe 6, and the drive motor 8 is started to rotate the controlled-release turntable 71. When the arc-shaped tooth segment 712 on the annular flange 711 of the controlled-release turntable 71 moves to the controlled-release gear 72, the controlled-release gear 72 engages with each tooth groove of the arc-shaped tooth segment 712 in sequence under the cooperation of the lever 722 and the paddle 713, and presses down the drug release bladder 73, thereby releasing the drug through the liquid pipe 76 into the dosing pipe 6, and entering the mixing chamber 2 along with the biogas slurry.

[0070] As the controlled-release disc 71 continues to rotate, the drug release bladder 73 loses the pressure of the controlled-release gear 72, and the liquid tube 76 enters the drug container 74. Under the action of the side wall of the drug container 74, the flexible tube 762 of the liquid tube 76 is bent. At this time, the inside of the drug release bladder 73 is under negative pressure. Then the liquid tube 76 enters the drug container 74 to restore its original position. Under negative pressure, the drug is drawn into the drug release bladder 73 in preparation for the next rotation of the controlled-release disc 71 to engage with the controlled-release gear 72.

[0071] Meanwhile, the controlled-release gear 72 drives the cam 77 to rotate intermittently via the rotating shaft. The cooperation between the cam 77 and the cam frame 771 causes the sealing plate 24 to intermittently open the partition that directly connects the mixing chamber 2 and the dosing pipe 6, thereby increasing the time for the aquaculture biogas slurry and the medicine to mix and remain.

[0072] Since the controlled release gear 72 rotates only within the arc-shaped toothed section 712 of the controlled release turntable 71, the opening interval of the sealing plate 24 can be significantly extended and controlled, thereby allowing the aquaculture biogas slurry and the agent to be stirred and retained for a longer period of time, and this function can be achieved without the need for an additional drive motor.

[0073] Example 2:

[0074] An application of a controllable aquaculture biogas slurry treatment device, based on a controllable aquaculture biogas slurry treatment device in Example 1, wherein the controllable aquaculture biogas slurry treatment device is used for the treatment and discharge of aquaculture biogas slurry, or for the production of liquid fertilizer from aquaculture biogas slurry.

[0075] Example 3:

[0076] The difference between this embodiment and Embodiment 1 is that, Figures 6-8 As shown, the controlled-release device is a water-driven controlled-release device, which includes a controlled-release mechanism 7 and a water wheel 9 connected to the controlled-release mechanism 7 via a shaft; the controlled-release turntable 71 is fixedly connected to the shaft of the water wheel 9.

[0077] The baffle 23 is provided with interlaced arc-shaped baffles 25 whose curved side is opposite to the flow direction of the S-shaped flow path. The arc-shaped baffles 25 are hinged to the baffle 23 by a torsion spring shaft, and the baffle 23 is provided with a baffle bar for limiting the swing angle of the arc-shaped baffles 25.

[0078] The working method of the above-mentioned controllable aquaculture biogas slurry treatment equipment is as follows:

[0079] Unlike the working method of Example 1, the water turbine 9 is driven to rotate by the injected biogas slurry, which in turn drives the controlled release turntable 71 to rotate via the shaft.

[0080] Based on the working method of Example 1, when the biogas slurry enters the mixing chamber 2, the arc-shaped baffle 25 can adaptively adjust according to the flow rate of the biogas slurry. For example, when the flow rate is high, the biogas slurry can push the arc-shaped baffle 25 to overcome the torque of the torsion spring shaft and deflect it, thereby reducing the width of the flow path and increasing the residence time of the biogas slurry, thereby improving the mixing time and effect of the biogas slurry and the agent.

[0081] Example 4:

[0082] The difference between this embodiment and Embodiment 1 is that, Figures 14-17As shown, a groove is provided on the end face of one side wall of the medicine box 74, and a bevel gear 741 and a first pulley 742 are rotatably arranged in the groove. A bevel ring 715 for meshing and driving with the bevel gear 741 is provided on the bottom surface of the controlled-release turntable 71. The bevel gear 741 and the first pulley 742 rotate coaxially through a rotating shaft.

[0083] The medicine box 74 is provided with several stirring shafts 743 along the horizontal direction. One end of the stirring shaft 743 passes through the cavity of the inner wall of the medicine box 74 and is provided with a second pulley 744. Each second pulley 744 and the first pulley 742 are connected by a transmission belt. The stirring shaft 743 is rotatably and sealedly connected to the inner wall of the medicine box 74.

[0084] The outer wall of the medicine box 74 is also provided with several air bladders 745, and the bottom surface of the controlled-release turntable 71 is provided with an arc-shaped plate 716 for pushing the air bladders 745. The air bladders 745 are rotatably and sealed to one end of the stirring shaft 743 through pipes.

[0085] The stirring shaft 743 is hollow inside and has multiple stirring blades 746 on it. The stirring shaft 743 also has multiple disturbance plates 748 that are connected to the inside of the stirring shaft 743 through airbag rods 747.

[0086] The medicine box 74 is divided into a drug delivery compartment and a replenishment compartment. The replenishment compartment is located above the drug delivery compartment. A drug delivery tube 78 is vertically arranged inside the replenishment compartment. The lower end of the drug delivery tube 78 passes through the replenishment compartment and extends into the drug delivery compartment. A drug delivery port 781 communicating with its lower end is provided on the middle side wall of the drug delivery tube 78. The upper end of the drug delivery tube 78 passes through the replenishment compartment and is provided with a tablet 783. A spring is sleeved on the drug delivery tube 78 located between the tablet 783 and the replenishment compartment. A swing plate 782 is provided on the replenishment compartment on one side of the drug delivery tube 78. The swing plate 782 is rotatably connected to the bracket provided on the replenishment compartment. One end of the swing plate 782 contacts the tablet 783, and the other end of the swing plate 782 extends to the controlled release gear 72 and is located above the lever 722.

[0087] The working method of the above-mentioned controllable aquaculture biogas slurry treatment equipment is as follows:

[0088] Based on the working method of Example 1, when the controlled release turntable 71 rotates, the bevel gear 741 is driven to rotate by the bevel gear ring 715, thereby causing the first pulley 742 to rotate. Through the belt drive action of the first pulley 742 and the second pulley 744, each stirring shaft 743 is rotated.

[0089] Meanwhile, as the controlled-release turntable 71 rotates, the arc plate 716 pushes the airbag 745 on the medicine box 74, thereby causing the airbag rod 747 to extend and retract, which in turn drives the disturbance plate 748 to disturb the medicine in the medicine box 74, enhancing the stirring effect.

[0090] During the rotation of the controlled-release gear 72, the swing plate 782 is periodically pushed, causing the swing plate 782 to periodically press down the drug delivery tube 78. This allows the drug delivery port 781 of the drug delivery tube 78 to periodically connect the replenishment chamber and the administration chamber, enabling the drug to be periodically and quantitatively replenished to the administration chamber, thus preventing the liquid tube 76 from failing to be submerged in the drug to complete the drug absorption operation.

[0091] Example 5:

[0092] The difference between this embodiment and Embodiment 1 is that, Figure 18 As shown, an MBR device is also installed above the sedimentation tank 3. The inlet of the MBR device is connected to the outlet 22 of the mixing tank 2 through a pipe, and the outlet of the MBR device is connected to the ozone reaction tower through a pipe. By adding the MBR device, the quality of the liquid fertilizer can be effectively improved, and suspended solids can be removed better. It can be understood that the MBR device refers to a commercially available membrane bioreactor. In addition, a commercially available filter press can be installed in the sedimentation tank 3, and the effluent can be reintroduced into the dosing pipe 6 for circulation treatment through a pipe.
