Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a stirring mechanism for a water treatment dosing device. Background Technology

[0002] A stirring mechanism in a water treatment dosing system is a specialized device used for dissolving, mixing, and transporting chemicals during water treatment processes. It is widely used in wastewater treatment, industrial circulating water, and drinking water purification. Its core function is to promote uniform mixing of chemicals and water through mechanical stirring, ensuring that the chemicals fully exert their chemical or physical effects, thereby improving water treatment efficiency. Traditional stirring mechanisms typically consist of a motor, reducer, stirring shaft, and blades, achieving mixing through the generation of eddies by rotation. With advancements in water treatment technology, the design of stirring mechanisms has been gradually optimized, resulting in various forms such as paddle, turbine, and propeller types to adapt to chemicals of different viscosities and operating conditions.

[0003] Existing stirring mechanisms have relatively simple structures, relying solely on a motor to drive the stirring shaft and blades to rotate within the mixing tank. The blades then drive the chemical solution to rotate and mix. This stirring method has a limited range of mixing, resulting in low stirring efficiency. Therefore, further improvements are needed. To address this, we propose a stirring mechanism for a water treatment dosing device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stirring mechanism for a water treatment dosing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a stirring mechanism for a water treatment dosing device, comprising a horizontal plate, a shaft tube rotatably connected through the middle of the horizontal plate via a bearing, the bottom end of the shaft tube being open, and an end plate being fixed to the bottom end of the shaft tube by bolts, a square hole being provided in the middle of the end plate, a square rod being slidably connected through the square hole, a stirring blade being fixed to the bottom end of the square rod, a detachable piston being fixed to the top end of the square rod, and the piston being slidably connected to the shaft tube, a spring being provided between the lower surface of the piston and the upper surface of the end plate, a motor for driving the shaft tube to rotate being mounted on the upper surface of the horizontal plate, an air pump for inflating the shaft tube being mounted on the other side of the upper surface of the horizontal plate, a hollow cover being fixed on the upper surface of the horizontal plate, the motor and the air pump being located inside the hollow cover, and a controller being fixed to the inner wall of the hollow cover.

[0006] Furthermore, a driven gear is fixed to the top surface of the shaft tube, a driving gear is fixed to the output end of the motor, the driving gear meshes with the driven gear, and the motor is electrically connected to the controller.

[0007] Furthermore, a hollow cover is rotatably sleeved on the top surface of the shaft tube via a sealed bearing, and multiple air holes are opened on the side wall of the shaft tube located inside the hollow cover. An air supply pipe is fixedly connected between the exhaust port of the air pump and the hollow cover.

[0008] Furthermore, a three-way solenoid valve is fixedly installed in the middle of the gas pipeline, and both the three-way solenoid valve and the gas pump are electrically connected to the controller.

[0009] Furthermore, an inspection cover is bolted to the top of the top shell.

[0010] Furthermore, ventilation openings are provided on the side wall of the top shell.

[0011] The beneficial effects of this utility model are:

[0012] 1. In use, this utility model is equipped with a horizontal plate, shaft tube, square rod, stirring blade, motor, hollow cover, air pump and spring. The motor drives the shaft tube, square rod and stirring blade to rotate, thereby stirring water and medicine. During the process, the air pump fills the shaft tube with air, causing the square rod and stirring blade to descend. When the air is exhausted, the spring pushes the square rod and stirring blade to rise, thereby realizing the rotation of the stirring blade and its up-and-down reciprocating motion, thus improving the stirring efficiency.

[0013] 2. In use, this utility model is provided with a shaft tube, a square rod, an end plate, a spring, and a piston. After the end plate is removed from the bottom of the shaft tube, the square rod and the piston can be pulled out from the bottom of the shaft tube, which facilitates the disassembly and replacement of the piston and ensures the sealing between the piston and the shaft tube.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 As shown, a stirring mechanism for a water treatment dosing device is disclosed, comprising a horizontal plate 1, a shaft tube 2 rotatably connected to the middle of the horizontal plate 1 via a bearing, the bottom end of the shaft tube 2 being open, and an end plate 3 being fixed to the bottom end of the shaft tube 2 by bolts, a square hole being provided in the middle of the end plate 3, a square rod 4 being slidably connected through the square hole, a stirring blade 5 being fixed to the bottom end of the square rod 4, and a detachable piston 11 being fixed to the top end of the square rod 4, the piston 11 being slidably connected to the shaft tube 2, a spring 12 being provided between the lower surface of the piston 11 and the upper surface of the end plate 3, a motor 6 for driving the shaft tube 2 to rotate being mounted on the upper surface of the horizontal plate 1, an air pump 8 for inflating the shaft tube 2 being mounted on the other side of the upper surface of the horizontal plate 1, a hollow cover 7 being fixed on the upper surface of the horizontal plate 1, the motor 6 and the air pump 8 being located inside the hollow cover 7, and a controller 14 being fixed to the inner wall of the hollow cover 7.

[0023] In this embodiment, the controller 14 adopts an S7-1200 series (small and medium-sized automation) CPU 1214C (6ES7214-1BG40-0XB0), and controls the operation of the motor 6 and the air pump 8 through the controller 14.

[0024] A driven gear 201 is fixed on the top surface of the shaft tube 2, and a driving gear 601 is fixed on the output end of the motor 6. The driving gear 601 meshes with the driven gear 201, and the motor 6 is electrically connected to the controller 14.

[0025] By starting the motor 6, the drive gear 601 at the output end of the motor 6 can drive the driven gear 201 to rotate, thereby driving the shaft tube 2 to rotate. Since the end plate 3 at the bottom of the shaft tube 2 has a square hole, the end plate 3 at the bottom of the shaft tube 2 will drive the square rod 4 to rotate synchronously, finally realizing the rotation of the stirring blade 5.

[0026] A hollow cover 7 is rotatably sleeved on the top surface of the shaft tube 2 through a sealed bearing. Multiple air holes 202 are opened on the side wall of the shaft tube 2 located inside the hollow cover 7. An air supply pipe 9 is fixedly connected between the exhaust port of the air pump 8 and the hollow cover 7.

[0027] By starting the air pump 8, air can be supplied into the hollow cover 7 through the air supply pipe 9. The air passes through the air hole 202 on the side wall of the shaft tube 2 and enters the interior of the shaft tube 2, thereby pushing the piston 11 to move downward. The piston 11 then drives the square rod 4 and the stirring blade 5 to descend. During the descent, the spring 12 will be compressed.

[0028] A three-way solenoid valve 10 is fixedly installed in the middle of the gas pipeline 9. Both the three-way solenoid valve 10 and the air pump 8 are electrically connected to the controller 14.

[0029] In this embodiment, the three-way solenoid valve 10 is an SMC VQZ332-5G-1. The controller 14 controls the three-way solenoid valve 10 to open or close, so that the air in the shaft tube 2 can be discharged along the three-way solenoid valve 10, thereby realizing the air discharge in the shaft tube 2. When the air inside the shaft tube 2 is discharged, the spring 12 will push the piston 11 and the square rod 4 to move upward, thereby driving the stirring blade 5 to move upward.

[0030] A maintenance cover is bolted to the top of the top shell 13. The maintenance cover facilitates internal maintenance of the top shell 13 by removing it.

[0031] The top shell 13 has ventilation openings 15 on its side wall. The ventilation openings 15 serve to dissipate heat and facilitate air extraction and exhaust.

[0032] Working principle: The horizontal plate 1 is installed on the top of the water treatment tank. During use, the controller 14 controls the motor 6 to drive the shaft tube 2, square rod 4 and stirring blade 5 to rotate, thereby mixing the medicine. At the same time, the controller 14 periodically controls the air pump 8 and the three-way solenoid valve 10 to work. When air is charged to the top of the shaft tube 2, the piston 11 pushes the square rod 4 and stirring blade 5 to descend. When air is vented from the inside of the shaft tube 2, the spring 12 pushes the piston 11, square rod 4 and stirring blade 5 to move upward and reset, so that the stirring blade 5 rotates and moves up and down inside the tank, increasing the mixing range and thus improving the mixing efficiency.

[0033] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
