Description

Technical Field

[0001] This application relates to the field of water treatment equipment technology, and in particular to a water treatment agent dosing device. Background Technology

[0002] In many fields involving water treatment, such as industrial production, wastewater treatment, and drinking water purification, various water treatment agents, such as disinfectants, flocculants, and descaling agents, need to be added to remove impurities, kill bacteria, and adjust the pH of the water to meet corresponding water treatment standards. Currently, common methods of agent dosing have some shortcomings, for example:

[0003] Some traditional dosing devices rely solely on simple manual timed and quantitative pouring, which makes it difficult to guarantee the accuracy of dosing. Human error can easily lead to excessive or insufficient dosage of chemicals, affecting the water treatment effect.

[0004] In addition, since most water treatment agents are in powder form, when a large amount of water treatment agent is required, directly adding a large amount of water treatment agent into the wastewater at once results in a slow dissolution rate. Furthermore, direct addition into the wastewater can easily cause the powder to clump or settle at the bottom, making it difficult to mix and dissolve, thus leading to low wastewater treatment efficiency. Therefore, a water treatment agent dosing device is proposed to solve the above problems. Utility Model Content

[0024] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0025] This application discloses a water treatment agent dosing device. (Refer to...) Figure 1-4 A water treatment agent dispensing device includes a frame 1. A hopper 2 is fixedly connected to the top outer wall of the frame 1 by a plurality of telescopic columns 5. A mixing box 3 is fixedly connected to the bottom outer wall of the frame 1. The hopper 2 is located directly above the mixing box 3. A quantitative dispensing mechanism is installed on the outer wall of the hopper 2. A stirring mechanism is installed inside the mixing box 3.

[0026] The quantitative dispensing mechanism includes a first door 8 and a second door 9 rotatably connected to the outer wall of the hopper 2 via a rotating shaft. The first door 8 and the second door 9 are symmetrically arranged. Two connecting plates 10 are fixedly connected to the top outer wall of the first door 8, and a fixed shaft 11 is fixedly connected to the outer wall of the connecting plate 10. Fixed shafts 12 are fixedly connected to the outer walls of the two sides of the second door 9. A connecting rod 13 is movably connected to the outer walls of the first and second fixed shafts 11 and the second fixed shaft 12. Two electric push rods 7 are movably connected to the top two outer walls of the frame 1. The output end of the electric push rod 7 is movably connected to the outer wall of the fixed shaft 11.

[0027] A controller 14 is installed on the outer wall of the frame 1. Two weight sensors 6 are fixedly installed on the top outer wall of the frame 1. The tops of the two weight sensors 6 abut against the bottom outer walls of both sides of the hopper 2. The two weight sensors 6 and the two electric push rods 7 are electrically connected to the controller 14.

[0028] The stirring mechanism includes a stirring shaft 16 rotatably connected to the inner wall of the bottom of the mixing tank 3 via a bearing 15. Two mounting rods 17 are fixedly connected to the outer wall of the stirring shaft 16, and two spiral belts 18 are fixedly connected to the outer wall of the two mounting rods 17.

[0029] The stirring mechanism also includes multiple stirring rods 19 fixedly connected to the outer wall of the stirring shaft 16. The multiple stirring rods 19 are evenly distributed in an array with equal spacing, and the multiple stirring rods 19 are located between two mounting rods 17.

[0030] A motor 20 is fixedly installed on the bottom middle outer wall of the mixing box 3. The output shaft of the motor 20 extends into the bearing 15 and is fixedly connected to the bottom end of the stirring shaft 16. The motor 20 is electrically connected to the controller 14.

[0031] The inner wall of the bearing 15 is provided with two sealing rings 23, which are tightly fitted to the outer wall of the stirring shaft 16.

[0032] A discharge port 21 is provided on the outer wall of the mixing box 3 near the bottom inner cavity, and a valve 22 is installed on the discharge port 21.

[0033] Multiple support legs 4 are fixedly connected to the bottom outer wall of the frame 1, and the multiple support legs 4 are evenly distributed at equal intervals.

[0034] The implementation principle of the water treatment agent dispensing device in this application embodiment is as follows: During use, a large amount of agent is added to the silo 2 at once, and then the controller 14 is set with a preset dispensing amount and dispensing speed. During the dispensing process, the weight sensor 6 monitors the weight of the agent in the silo 2 in real time and transmits the data to the controller 14. The controller 14 controls the operation of the quantitative dispensing mechanism according to the preset values.

[0035] Specifically, when it is necessary to open the bottom of the hopper 2, the controller 14 controls the electric push rod 7 to start. The output end of the electric push rod 7 retracts, driving the hopper door 8 to rotate around the pivot through the fixed shaft 11 and the connecting plate 10. When the fixed shaft 11 is pulled by the output end of the electric push rod 7, it pushes the connecting rod 13 to the right. The connecting rod 13 moves to the right and drives the hopper door 9 to rotate around the pivot through the fixed shaft 12. At this time, the hopper door 8 and the hopper door 9 rotate in opposite directions around the pivot, and the bottom ends of the hopper door 8 and the hopper door 9 move away from each other, opening the bottom of the hopper 2 and discharging the medicine in the hopper 2. The controller 14 can control the opening and closing size of the bottom ends of the hopper door 8 and the hopper door 9 by real-time control of the degree of retraction of the electric push rod 7, thereby controlling the dispensing speed.

[0036] When the weight sensor 6 detects that the weight of the medicine in the hopper 2 has decreased to the preset value of the controller 14, it transmits a signal to the controller 14. The controller 14 then controls the output end of the electric push rod 7 to fully extend according to the signal, thereby pushing the fixed shaft 11 to move to the left. The fixed shaft 11 drives the connecting plate 10 and the hopper door 8 to rotate in the opposite direction around the rotating shaft. At this time, the fixed shaft 11 pulls the connecting rod 13 to the left. The connecting rod 13 pulls the hopper door 9 to rotate in the opposite direction around the rotating shaft through the fixed shaft 2 12. The bottom ends of the hopper door 8 and the hopper door 9 move closer and touch each other synchronously, closing the bottom of the hopper 2 and stopping the dispensing. This achieves accurate measurement and automated dispensing, completing one dispensing process.

[0037] When the agent falls into the silo 2, water is added to the silo 2 and the motor 20 is started. The output shaft of the motor 20 drives the stirring shaft 16 to rotate, which in turn drives the stirring rod 19 to rotate. The mounting rod 17 drives the spiral belt 18 to rotate. Through the cooperation of the stirring rod 19 and the spiral belt 18, the agent and water can be fully and evenly mixed, improving the dissolution rate of the agent. After the mixing is completed, the valve 22 is opened and the mixed agent is discharged through the discharge port 21 to enter the subsequent water treatment stage.
