[0003] In the prior art, including the aforementioned patents, current water treatment dosing systems have the following problems: First, the dosage accuracy of the chemicals can only be controlled by one drive to control one dosing unit, resulting in high energy consumption. If it is a mechanical linkage structure, it will cause mutual interference between the dosing units, making it impossible to achieve independent and precise control of different chemicals (such as the dosage accuracy of scale inhibitors and corrosion inhibitors), thus making it impossible to dosing the chemicals in a targeted manner according to the quality of the water system.
[0004] Therefore, a dosing device with the function of quantitatively dispensing multiple water treatment agents is needed to solve the above problems. Summary of the Invention
[0005] The purpose of this invention is to provide a dosing device with multiple water treatment agents quantitative dispensing functions to solve the technical problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a dosing device with multiple water treatment agents quantitative dosing functions, comprising a agent tank, a driving device installed on the top of the agent tank, the driving device being connected to a rotary drive device, one rotary drive device being connected to two other rotary drive devices via a transmission rod, the transmission rod being rotatably connected to a support frame, the rotary drive device being rotatably connected to the upper end of a top block, and the rotary drive device being connected to an inlet / outlet device.
[0007] Furthermore, the driving device includes a motor connected to a medicine tank, a small gear meshing with a large gear, a slide rod connected to one side of the large gear, a rotatable and slidable connection between the slide rod and a rocker arm through a groove, and a rotary drive device.
[0008] Furthermore, the rotary drive device includes a half gear, which is connected to a transmission rod and a rocker arm. The half gear meshes with a rack on one side, and a sliding groove is formed on the other side of the rack. The sliding groove is slidably connected to a slider, the slider is connected to a support rod, the lower end of the rack is rotatably connected to a pressure rod, and both sides of the pressure rod are rotatably connected to a top block.
[0009] Furthermore, symmetrical grooves are provided on both sides of the pressure rod, the symmetrical grooves are rotatably and slidably connected to the top block, the bottom of the top block is threadedly connected to the threaded rod, the threaded rod is rotatably connected to the locking block, the locking block is engaged with the toothed block, and the toothed block is fixedly connected to the support frame.
[0010] Furthermore, a scale is provided on one side of the top block, and the scale is fixedly connected to the support frame.
[0011] Furthermore, the top block includes symmetrically arranged side blocks, each of which is connected to a pull block. The pull blocks are connected to both ends of a reset elastic member, and the reset elastic member is slidably connected to the bottom block through a perforation.
[0012] Furthermore, the inlet and outlet device includes a cylinder body, the outer ring of the cylinder body is connected to a support frame, a block is provided at the upper end of the cylinder body, the block is slidably and rotatably connected to the pressure rod, the block is connected to one end of a pull rod, the other end of the pull rod is connected to a piston, the piston is slidably connected to the cylinder body, the lower outer ring of the cylinder body is connected to one end of an inlet pipe, a first check valve is installed at one end of the inlet pipe, the other end of the inlet pipe is connected to a medicine tank, the bottom of the cylinder body is connected to one end of an outlet pipe, and a second check valve is installed on the outlet pipe.
[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] (1) The horizontal movement of the top block dynamically adjusts the displacement of the pressure rod and the inlet / outlet device by changing the position of the fulcrum connected to the pressure rod. When the top block moves towards the power end of the pressure rod, the lever ratio decreases, so that the output end of the pressure rod obtains a larger reciprocating stroke and a stronger downward pressure, thereby increasing the dosage of the drug. Conversely, when the top block moves away from the power end, the lever ratio increases, which can achieve precise control of the small flow rate of the drug. At the same time, the fine adjustment function of the threaded rod can achieve the control of the dosage accuracy. The self-locking structure of the locking block and the toothed block ensures that the mechanical parameters after adjustment are stable for a long time, ensuring stable flow control. The scale provides the operator with an intuitive displacement reference. With the horizontal movement of the top block, high-precision fulcrum positioning can be achieved, ensuring accurate control of the drug dosage.
[0015] (2) The drive device drives the rotary drive device to move through the motor. The drive device links other drive devices through the transmission rod, and drives the top block and the inlet and outlet devices to work together to realize the quantitative extraction and discharge of the agent. By linking multiple drive devices through the transmission rod, the quantitative dispensing of multiple agents can be controlled at the same time to improve efficiency. The operator pulls the symmetrically set pull block to the outside to drive the side block to overcome the pre-tightening force of the reset elastic element and move outward. The contact surface between the side block and the pressure rod symmetrical groove is separated, realizing the immediate separation of the top block and the pressure rod. Thus, when a certain agent is not needed, the addition of that agent is stopped. Attached Figure Description

Detailed Implementation
[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0027] Please see Figures 1 to 9 The present invention provides a technical solution: a dosing device with multiple water treatment agents quantitative dispensing functions, comprising a agent tank 1, which has several partitioned slots for holding agents for several inlet and outlet devices 4. A drive device 2 is installed on the top of the agent tank 1. The drive device 2 is driven by a rotary drive device 3. One rotary drive device 3 is driven by two other rotary drive devices 3 through a transmission rod 7. The transmission rod 7 is rotatably connected to a support frame 6. The rotary drive device 3 is rotatably connected to the upper end of a top block 5. The rotary drive device 3 is driven by the inlet and outlet devices 4. The drive device 2 drives the rotary drive device 3 to move through a motor 21. The drive device 2 is linked to other drive devices 2 through the transmission rod 7, driving the top block 5 and the inlet and outlet devices 4 to work together to realize the quantitative extraction and discharge of agents. By linking multiple drive devices 2 through the transmission rod 7, the quantitative dispensing of multiple agents can be controlled simultaneously, improving efficiency.
[0028] The driving device 2 includes a motor 21, which is connected to the medicine tank 1. The motor 21 is driven by a pinion 22, which meshes with a large gear 23. One side of the large gear 23 is connected to a slide rod 25. The slide rod 25 is rotatably and slidably connected to a groove 331 on a rocker arm 24. The slide rod 25 is driven by a rotary drive device 3. The motor 21 drives the pinion 22 to mesh with the large gear 23. The large gear 23 slides in the groove 331 of the rocker arm 24 through the slide rod 25, converting the rotational motion into the reciprocating oscillation of the rocker arm 24, thereby driving the rotary drive device 3. This method converts the rotational motion into an incomplete circular reciprocating motion, ensuring the stability of the operation.
[0029] The rotary drive device 3 includes a half gear 32, which is connected to the transmission rod 7 and the rocker arm 24. The half gear 32 meshes with the rack 33 on one side, and the rack 33 has a sliding groove 331 on the other side. The sliding groove 331 is slidably connected to the slider 35, and the slider 35 is connected to the support rod 34. The lower end of the rack 33 is rotatably connected to the pressure rod 36, and the two sides of the pressure rod 36 are rotatably connected to the top block 5. The half gear 32 drives the rack 33 to make vertical reciprocating motion, providing input force to one end of the pressure rod 36. The middle part forms a rotatable fulcrum with the top block 5 through a symmetrical groove, and the other end forms a pressure output end, thereby driving the inlet and outlet device 4 to pump out the medicine.
[0030] The pressure rod 36 has symmetrical grooves on both sides, which are rotatably and slidably connected to the top block 5. The bottom of the top block 5 is threadedly connected to the threaded rod 52, which is rotatably connected to the locking block 51. The locking block 51 engages with the toothed block 53, which is fixedly connected to the support frame 6. The horizontal movement of the top block 5 changes the position of the fulcrum connected to the pressure rod 36, dynamically adjusting the displacement of the pressure rod 36 and the inlet / outlet device 4. When the top block 5 moves towards the power end of the pressure rod 36, the lever ratio decreases, allowing the output end of the pressure rod 36 to obtain a larger reciprocating stroke and stronger downward pressure, thereby increasing the dosage. Conversely, when the top block 5 moves away from the power end, the lever ratio increases, enabling precise control of the small flow rate of the drug. Simultaneously, the fine-tuning function of the threaded rod 52 allows for precise control of the dosage, and the self-locking structure of the locking block 51 and the toothed block 53 ensures long-term stability of the adjusted mechanical parameters, guaranteeing stable flow control.
[0031] A scale 54 is provided on one side of the top block 5. The scale 54 is fixedly connected to the support frame 6. The scale 54 provides the operator with an intuitive displacement reference. In conjunction with the horizontal movement of the top block 5, high-precision fulcrum positioning can be achieved to ensure accurate control of the dosage of the agent.
[0032] The top block 5 includes symmetrically arranged side blocks 502, each of which is connected to a pull block 504. The pull blocks 504 are connected to both ends of a reset elastic member 503. The reset elastic member 503 is slidably connected to the bottom block 501 through a perforation. When the operator pulls the symmetrically arranged pull blocks 504 outward, the side blocks 502 overcome the preload of the reset elastic member 503 and move outward, separating the contact surface between the side blocks 502 and the symmetrical groove of the pressure rod 36, thereby realizing the immediate disengagement of the top block 5 from the pressure rod 36. This allows the addition of a certain agent to be stopped when it is not needed.
[0033] The inlet / outlet device 4 includes a cylinder 41. The outer ring of the cylinder 41 is connected to the support frame 6. A block 42 is provided at the upper end of the cylinder 41. The block 42 is slidably and rotatably connected to the pressure rod 36. The block 42 is connected to one end of the pull rod 43. The other end of the pull rod 43 is connected to the piston 44. The piston 44 is slidably connected to the cylinder 41. The lower outer ring of the cylinder 41 is connected to one end of the liquid inlet pipe 45. A first check valve that can only allow the drug to enter the cylinder 41 is installed at one end of the liquid inlet pipe 45. The other end of the inlet pipe 45 is connected to the medicine tank 1, and the bottom of the cylinder 41 is connected to one end of the drain pipe 46. A second check valve that can only introduce medicine into the water system is installed in the drain pipe 46. The piston 44 moves downward by pushing the pull rod 43 through the block 42. The first check valve closes and the second check valve opens, so the medicine is discharged into the water system. When the piston 44 moves upward, it generates negative pressure, which opens the first check valve and closes the second check valve. The medicine is then drawn into the cylinder 41 from the medicine tank 1, forming a complete cycle.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
