[0003] In the existing technologies including the above-mentioned patents, the current water treatment dosing system has the following problems: First, the dosage accuracy of the reagent can only be achieved by controlling one dosing unit with one drive, which leads to high energy consumption. If a mechanical linkage structure is used, it will cause mutual interference between the dosing units, and it is impossible to achieve independent and precise control of different reagents (such as the dosage accuracy of scale inhibitors and corrosion inhibitors), thereby failing to carry out targeted dosing according to the quality of the water system.

[0004] Therefore, a dosing device with the function of quantitatively dosing multiple water treatment chemicals is needed to solve the above problems. Summary of the Invention

[0005] The object of the present invention is to provide a dosing device with a quantitative dosing function for a variety of water treatment chemicals, so as to solve the technical problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a dosing device with a function of quantitatively dosing multiple water treatment chemicals, comprising a chemical box, a driving device installed on the top of the chemical box, the driving device being transmission-connected to a rotary drive device, one of the rotary drive devices being transmission-connected to the other two rotary drive devices via a transmission rod, the transmission rod being rotationally connected to the support frame, the rotary drive device being rotationally connected to the upper end of the top block, and the rotary drive device being transmission-connected to the supply and discharge device.

[0007] Furthermore, the driving device includes a motor, which is connected to the medicine box, which is connected to a small gear, which is meshed with a large gear, and one side of the large gear is connected to a slide rod, which is rotated and slidably connected to a slide groove opened by a rocker, and the slide rod is connected to a rotary drive device.

[0008] Furthermore, the rotation drive device includes a half gear, which is connected to the transmission rod and the rocker transmission, the half gear is meshed with one side of the gear rod, and a slide groove is provided on the other side of the gear rod, the slide groove is slidably connected to the slider, the slider is connected to the support rod, the lower end of the gear rod is rotatably connected to the pressure rod, and the two sides of the pressure rod are rotatably connected to the top block.

[0009] Furthermore, symmetrical grooves are opened on both sides of the pressure rod, the symmetrical grooves are rotatably and slidingly 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 clamping block, the clamping block is clamped with the tooth block, and the tooth 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 the side blocks 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 the support frame, a mold block is provided at the upper end of the cylinder body, the mold block is slidably and rotatably connected to the pressure rod, the mold block is connected to one end of the pull rod, the other end of the pull rod is connected to the piston, the piston is slidably connected to the cylinder body, the outer ring of the lower end of the cylinder body is connected to one end of the liquid inlet pipe, one end of the liquid inlet pipe is installed with a first check valve, the other end of the liquid inlet pipe is connected to the medicine box, the bottom of the cylinder body is connected to one end of the discharge pipe, and the discharge pipe is installed with a second check valve.

[0013] Compared with the prior art, the present invention has the following beneficial effects: (1) The horizontal movement of the top block dynamically adjusts the displacement of the pressure rod and the inlet and outlet device by changing the position of the fulcrum connected to the pressure rod. When the top block moves toward the power end of the pressure rod, the lever ratio is reduced, so that the output end of the pressure rod obtains a larger reciprocating stroke and a stronger downward force, thereby increasing the amount of medicine injected. Conversely, when the top block moves away from the power end, the lever ratio is increased, which can achieve precise control of the discharge of small flow rates of medicine. At the same time, the fine-tuning function of the threaded rod can achieve the control of the injection accuracy, and the self-locking structure of the block and the tooth block ensures the long-term stability of the adjusted mechanical parameters and the stability of the flow control. The scale provides an intuitive displacement reference for the operator. In conjunction with the horizontal movement of the top block, high-precision fulcrum positioning can be achieved to ensure accurate control of the amount of medicine injected.

[0014] (2) The driving device drives the rotary drive device to move through the motor, and the driving device is linked to other driving devices through the transmission rod, driving the top block and the feed and discharge device to work together to realize the quantitative extraction and discharge of the medicine. By linking multiple driving devices through the transmission rod, the quantitative delivery of multiple medicines can be controlled at the same time to improve efficiency; the operator pulls the symmetrically arranged pull blocks outward to drive the side blocks to overcome the pre-tightening force of the reset elastic member and move outward to separate the contact surface of the side blocks and the symmetrical groove of the pressure rod, thereby realizing the immediate separation of the top block and the pressure rod, thereby stopping the addition of a certain medicine when it is no longer needed.

DETAILED DESCRIPTION

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0018] See also Figures 1 to 9 , the present invention provides a technical solution: a dosing device with a quantitative dosing function of multiple water treatment chemicals, including a chemical box 1, which is provided with several partition slots for loading chemicals according to several inlet and outlet devices 4. A driving device 2 is installed on the top of the chemical box 1, and the driving device 2 is transmission-connected to a rotary drive device 3, and one of the rotary drive devices 3 is transmission-connected to the other two rotary drive devices 3 through a transmission rod 7, and the transmission rod 7 is rotationally connected to the support frame 6, and the rotary drive device 3 is rotationally connected to the upper end of the top block 5, and the rotary drive device 3 is transmission-connected to the inlet and outlet device 4; the driving device 2 drives the rotary drive device 3 to move through the motor 21, and the driving device 2 is linked to other driving devices 2 through the transmission rod 7, driving the top block 5 and the inlet and outlet device 4 to work together to realize the quantitative extraction and discharge of chemicals, and by linking multiple driving devices 2 through the transmission rod 7, the quantitative dosing of multiple chemicals can be controlled at the same time, thereby improving efficiency.

[0019] The driving device 2 includes a motor 21, which is connected to the medicine box 1. The motor 21 is connected to the small gear 22, which is meshed with the large gear 23. One side of the large gear 23 is connected to the slide bar 25. The slide bar 25 is rotated and slidably connected to the slide groove 331 opened by the rocker 24. The slide bar 25 is connected to a rotary drive device 3. The motor 21 drives the small gear 22 to mesh with the large gear 23. The large gear 23 slides in the slide groove 331 of the rocker 24 through the slide bar 25, converting the rotational motion into the reciprocating swing of the rocker 24, and then driving the rotation drive device 3. This method converts the rotational motion into an incomplete circular reciprocating motion to ensure the stability of the movement.

[0020] The rotary drive device 3 includes a half gear 32, which is in transmission connection with the transmission rod 7 and the rocker 24. The half gear 32 is meshed with one side of the gear rod 33, and a slide groove 331 is provided on the other side of the gear rod 33.

The lower end of the gear rod 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.

[0021] Symmetrical grooves are provided on both sides of the pressure rod 36, and the symmetrical grooves 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, and the threaded rod 52 is rotatably connected to the block 51. The block 51 is engaged with the tooth block 53, and the tooth block 53 is fixedly connected to the support frame 6. The horizontal movement of the top block 5 is achieved by changing the position of the fulcrum connected to the pressure rod 36, dynamically adjusting the displacement of the pressure rod 36 and the feed and discharge device 4. When the top block 5 moves toward the power end of the pressure rod 36, the lever ratio is reduced, so that the output end of the pressure rod 36 obtains a larger reciprocating stroke and a stronger downward force, thereby increasing the amount of medicine added; conversely, when the top block 5 moves away from the power end, the lever ratio is increased, which can achieve precise control and discharge of small flow rates of medicine. At the same time, the fine-tuning function opened by the threaded rod 52 can achieve control of the dosing accuracy, and the self-locking structure of the block 51 and the tooth block 53 ensures the long-term stability of the adjusted mechanical parameters and stable flow control.

[0022] A scale 54 is provided on one side of the top block 5, and the scale 54 is fixedly connected to the support frame 6. The scale 54 provides an intuitive displacement reference for the operator, and cooperates with the horizontal movement of the top block 5 to achieve high-precision fulcrum positioning, ensuring accurate control of the dosage of the drug.

[0023] The top block 5 includes symmetrically arranged side blocks 502, and the side blocks 502 are each 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 slidingly connected to the bottom block 501 through a perforation. The operator pulls the symmetrically arranged pull blocks 504 outward to drive the side blocks 502 to overcome the pre-tightening force of the reset elastic member 503 and move outward to separate the contact surface of the side blocks 502 from the symmetrical groove of the pressure rod 36, thereby realizing the immediate separation of the top block 5 from the pressure rod 36, thereby stopping the addition of a certain medicine when it is no longer needed.

[0024] The inlet and outlet device 4 includes a cylinder 41, the outer ring of the cylinder 41 is connected to the support frame 6, a mold block 42 is provided at the upper end of the cylinder 41, the mold block 42 is slidably and rotatably connected to the pressure rod 36, the mold 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 outer ring of the lower end of the cylinder 41 is connected to one end of the liquid inlet pipe 45, and a first check valve is installed at one end of the liquid inlet pipe 45 that can only allow the medicine to be introduced into the cylinder 41. The other end of the liquid inlet pipe 45 is connected to the medicine box 1, and the bottom of the cylinder 41 is connected to one end of the liquid discharge pipe 46.
