This device offers advantages such as simple operation, time and labor saving, and automatic addition of agents to ensure a complete reaction. However, the device has the following shortcomings during use:

[0004] First, the quantitative addition structure of the reagent in this device is achieved through a rotating rod, a second motor, a driving rod, a connecting rod, a hinge rod, a reaction box, and a sliding rod. However, the range of reagent suction remains unchanged, and it is impossible to adjust the maximum and minimum quantitative suction volume, thus limiting its applicability.

[0005] In addition, the device needs to draw the liquid from the medicine tank, and the liquid in the medicine tank needs to be replenished manually. This can easily lead to insufficient liquid and failure to supply the liquid in time, thus affecting the quantitative addition of the medicine. Utility Model Content

[0006] To address the aforementioned problems, this invention proposes a quantitative addition device for water treatment tanks, which more accurately solves the issues of the inability to adjust the maximum and minimum quantitative suction volume in the tank and the need for manual replenishment of the solution.

[0007] This utility model is achieved through the following technical solution:

[0008] This utility model proposes a quantitative dosing device for water treatment tanks, including a storage tank, a stirring tank at the bottom of the storage tank, and a quantitative dosing mechanism between the storage tank and the stirring tank. A central column is fixedly connected to the center of the inner wall of the top of the storage tank, and a float plate is slidably connected to the outer wall of the central column. A liquid level control mechanism is provided on one side of the outer wall of the storage tank.

[0016] The beneficial effects of this utility model are:

[0017] This utility model proposes a water treatment tank chemical quantitative addition device. Through the cooperation of a dosing cylinder, a cylinder, a pusher piston, a lead screw, a baffle plate, and a long rod, the cylinder pushes the pusher piston back and forth to achieve quantitative addition of chemicals. By rotating the long rod to drive the lead screw to rotate, the baffle plate can be controlled to move closer to or further away from the pusher piston, changing the volume between the pusher piston and the baffle plate. This allows for adjustment of the maximum and minimum quantitative suction volume according to needs, effectively increasing the applicability of the device.

Detailed Implementation

[0026] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0027] Please refer to Figures 1-5 This utility model proposes a quantitative dosing device for water treatment tanks, including a storage tank 1, a stirring tank 14 at the bottom of the storage tank 1, and a quantitative dosing mechanism 2 between the storage tank 1 and the stirring tank 14. A central column 3 is fixedly connected to the center of the inner wall of the top of the storage tank 1, and a float plate 4 is slidably connected to the outer wall of the central column 3. A liquid level control mechanism 5 is provided on one side of the outer wall of the storage tank 1.

[0028] The quantitative dosing mechanism 2 includes a dosing cylinder 21 disposed between the storage tank 1 and the mixing tank 14, a cylinder 22 fixedly connected to the outer wall of one end of the dosing cylinder 21 by screws, a pusher piston 23 fixedly connected to the piston rod of the cylinder 22, a lead screw 24 screwed to the inner wall of one side of the pusher piston 23, a baffle plate 25 welded to the outer wall of one end of the lead screw 24, and a long rod 26 welded to the outer wall of the other side of the baffle plate 25, wherein the long rod 26 is slidably connected to the outer wall of the other end of the dosing cylinder 21.

[0029] The liquid level control mechanism 5 includes two adjacent fixed plates 51 welded to one side of the outer wall of the liquid storage tank 1, a guide rod 52 fixedly connected between the two fixed plates 51, a sliding sleeve 53 with a fastening knob and adjacently distributed on the outer wall of the guide rod 52, and a liquid level sensor 54 fixedly connected to one side of the outer wall of the sliding sleeve 53.

[0030] In this embodiment, through the cooperation of the dosing cylinder 21, cylinder 22, pusher piston 23, lead screw 24, baffle plate 25 and long rod 26, the cylinder 22 pushes the pusher piston 23 back and forth to achieve quantitative addition of the agent. By rotating the long rod 26 to drive the lead screw 24 to rotate, the baffle plate 25 can be controlled to move closer to or further away from the pusher piston 23, changing the volume between the pusher piston 23 and the baffle plate 25. The maximum and minimum quantitative suction volume can be adjusted according to the needs, effectively increasing the applicability of the device.

[0031] Meanwhile, through the cooperation of the fixing plate 51, guide rod 52, sliding sleeve 53 and liquid level sensor 54, the two liquid level sensors 54 can act as limit switches. By observing the height of the float 4, the water level change of the storage tank 1 can be monitored in real time, avoiding the problem of overflow due to excessive reagent or difficulty in adding reagent due to insufficient reagent. This realizes the automatic monitoring of the water level inside the storage tank 1 and ensures the normalization of quantitative addition of reagent.

[0032] A liquid intake pipe 6 is welded between the storage tank 1 and the dosing cylinder 21, and a drain pipe 7 is welded between the dosing cylinder 21 and the mixing tank 14. The reagent in the storage tank 1 flows into the dosing cylinder 21 through the liquid intake pipe 6, and then flows into the mixing tank 14 through the drain pipe 7. A limit ring 8 is provided on the inner wall of the dosing cylinder 21 near the push piston 23. The limit ring 8 is used to block the push piston 23, facilitating the intake or exhaust of air through the vent pipe 9.

[0033] Both ends of the top outer wall of the dosing cylinder 21 are equipped with vent pipes 9, and the top outer wall of the storage tank 1 is equipped with a second vent pipe 10. During the movement of the push piston 23 and the baffle plate 25, air will be introduced or exhausted through the vent pipes 9 to maintain the internal air pressure balance of the dosing cylinder 21. A replenishment pipe 11 is fixedly connected to the top outer wall of the storage tank 1, and a water pump 12 and a solenoid valve 13 are installed on the outer wall of the replenishment pipe 11. After opening the solenoid valve 13, the water pump 12 can replenish the agent into the storage tank 1.

[0034] A stirring motor 15 is bolted to the outer wall of the mixing tank 14, and a stirring rod is fixedly connected to the output shaft of the stirring motor 15 via a coupling. The stirring rod is located inside the mixing tank 14. A water inlet pipe 16 is fixedly connected to the top outer wall of the mixing tank 14, and a solenoid valve 17 is installed on the outer wall of the water inlet pipe 16. A discharge valve 18 with a discharge pipe is installed on the bottom outer wall of the mixing tank 14. After opening the solenoid valve 17, the water inlet pipe 16 can replenish water into the storage tank 1 to mix and dilute the agent, facilitating the subsequent addition of the agent to the water treatment tank in proportion.

[0035] When using this device, firstly, according to the liquid supply requirements, the long rod 26 is rotated to drive the lead screw 24 to rotate and control the baffle plate 25 to move closer to or further away from the pusher piston 23, thereby changing the volume between the pusher piston 23 and the baffle plate 25. After the volume is determined, the agent in the storage tank 1 will flow into the dosing cylinder 21 through the liquid extraction pipe 6. Then, the cylinder 22 pushes the pusher piston 23 to squeeze the agent into the drain pipe 7 and flow into the mixing tank 14 for stirring. The mixed and diluted agent can be added to the water treatment tank in proportion.

[0036] At the same time, the height of the float 4 is observed by two liquid level sensors 54 to monitor the water level change of the storage tank 1. If the agent is too low, the liquid can be supplied by the water pump 12 until the water level is on one side of the liquid level sensor 54 at the higher position and then the liquid supply is stopped.

[0037] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
