Description

Technical Field

[0001] This utility model relates to the technical field of cooling water dosing equipment, specifically a cooling water dosing device. Background Technology

[0002] The field of cooling water chemical dosing technology focuses on optimizing the performance, protecting equipment, and improving efficiency of industrial cooling water systems by adding specific chemical agents. These chemicals prevent scale formation, inhibit corrosion, control microbial growth, and stabilize water quality. This field involves knowledge from multiple disciplines, including chemistry, thermodynamics, fluid mechanics, and materials science, to ensure the safe and reliable operation of cooling systems and to meet environmental requirements. With increasing focus on energy efficiency and environmental protection, cooling water treatment technologies are constantly evolving to reduce the use of chemicals and wastewater discharge, while exploring more environmentally friendly and efficient alternatives, such as biodegradable agents and green technologies.

[0003] Cooling water dosing systems are devices specifically designed for industrial cooling water systems to precisely add necessary chemical agents to circulating water. These systems typically include a storage tank, metering pump, mixer, and control system to ensure the stable injection of chemicals at predetermined ratios to achieve purposes such as scale prevention, corrosion control, and microbial inhibition. By automatically monitoring and adjusting the dosage, cooling water dosing systems not only optimize water treatment results and extend equipment lifespan but also help reduce operating costs and environmental impact, making them an indispensable part of modern industrial cooling systems.

[0004] In existing technologies, cooling water dosing devices typically lack a pressure stabilizing mechanism. During the dosing process into the cooling water circulation system, the internal pipeline pressure of the cooling water circulation system will inevitably increase. The pressure fluctuation or increase in the internal pipeline may not only affect the accurate dosing of the agent, but may also have a negative impact on the stable operation of the system, such as causing a decrease in pump efficiency, increased energy consumption, damage to pipelines and equipment seals, and even leading to safety risks.

[0014] 1. The liquid medicine is stored in a storage tank. The connecting pipe is connected to the cooling water circulation system through the inlet and outlet valves. The liquid medicine in the storage tank is pumped into the connecting pipe through the inlet pipe by a metering pump. During this process, a spring provides elastic force to the connecting pipe, so that when the pressure inside the connecting pipe is too high, the liquid overcomes the elastic force of the spring and enters the liquid storage tank. When the pressure returns to normal, the liquid flows back from the liquid storage tank into the connecting pipe, thereby balancing the pressure inside the circulation system. During this process, a one-way valve prevents the cooling water on the inlet pipe side from flowing back, thus preventing the liquid medicine from flowing into the liquid storage tank.

In summary, when the motor is running, the stirring shaft will revolve around the axis of the connecting shaft and rotate around the axis of the third gear.

A connecting pipe 404 is installed, and a one-way valve 405 is provided on the side of the connecting pipe 404 away from the liquid inlet valve 402. A liquid inlet pipe 406 is provided on the side of the one-way valve 405 away from the connecting pipe 404.

A liquid storage shell 407 is fixedly connected to the top of the connecting pipe 404. An installation rod 408 is fixedly installed inside the liquid storage shell 407. A piston 409 is slidably installed on the installation rod 408. A spring 410 is provided on the side of the piston 409 away from the connecting pipe 404.

[0024] A control box 6 is fixedly installed on one side of the mounting bracket 1, and the operation of the entire equipment is controlled through the control box 6;

[0025] A flow meter 411 is installed between the liquid inlet valve 402 and the connecting pipe 404. The flow meter 411 detects the liquid flow rate inside the connecting pipe 401, and controls the operation of the metering pump 3 based on the flow data, thereby achieving the purpose of precise dosing according to the cooling water flow rate.

[0026] A level gauge 9 is fixedly installed on the top of the storage tank 2. The level gauge 9 is used to detect the liquid level inside the storage tank 2, so that personnel can easily replenish the liquid.

[0027] The specific implementation method is as follows: The storage tank 2 stores the liquid medicine. The connecting pipe 401 is connected to the interior of the cooling water circulation system through the inlet valve 402 and the outlet valve 403. The liquid medicine inside the storage tank 2 is pumped into the interior of the connecting pipe 401 through the inlet pipe 406 by the metering pump 3. During this process, the spring 410 provides elastic force towards the connecting pipe 404, so that when the pressure inside the connecting pipe 401 is too high, the liquid overcomes the elastic force of the spring 410 and enters the interior of the storage shell 407. When the pressure returns to normal, the liquid flows back from the interior of the storage shell 407 to the interior of the connecting pipe 401, thereby achieving the effect of balancing the internal pressure of the circulation system. During this process, the one-way valve 405 prevents the cooling water on the side of the inlet pipe 406 from flowing back, thereby preventing the liquid medicine from flowing into the interior of the storage shell 407.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a cooling water dosing device, wherein the stirring mechanism 5 includes a motor 501 and a mounting plate 502. The motor 501 is fixedly installed on the top of the storage tank 2, and the mounting plate 502 is fixedly installed on the bottom of the storage tank 2. The bottom of the output shaft of the motor 501 is fixedly connected to a connecting shaft 504 via a coupling. A geared disc 503 is fixedly installed on the bottom of the mounting plate 502. The connecting shaft 504 is rotatably installed inside the mounting plate 502 and the geared disc 503. A mounting block 505 is fixedly installed on the bottom of the connecting shaft 504. A plurality of first gears 506 are rotatably mounted on the top of the mounting block 505, a plurality of second gears 507 are rotatably mounted on the bottom of the mounting block 505, and a plurality of third gears 508 are rotatably mounted on the bottom of the mounting block 505.

[0029] The bottom of the mounting bracket 1 is fixedly installed with a pump pipe 7. The pump pipe 7 is fixedly connected to the bottom of the metering pump 3. The pump pipe 7 is made of rigid material. The metering pump 3 pumps the liquid medicine inside the storage tank 2 through the pump pipe 7. The pump pipe 7 is made of rigid material to ensure that the pump pipe 7 will not swing with the water flow and to prevent the pump pipe 7 from being stirred into the interior of the stirring mechanism 5.

[0030] A filter head 8 is fixedly connected to the bottom of the pump pipe 7. The filter head 8 prevents impurities inside the liquid from entering the metering pump 3 through the pump pipe 7.

[0031] The specific implementation method is as follows: the motor 501 drives the connecting shaft 504 to rotate, which in turn drives the mounting block 505 and the stirring shaft 510 to rotate. During this process, the gear disk 503 drives the first gear 506 to rotate, which in turn drives the third gear 508 to rotate through the second gear 507. Finally, the third gear 508 drives the stirring shaft 510 to rotate through the extension rod 509. In summary, when the motor 501 is running, the stirring shaft 510 will revolve around the axis of the connecting shaft 504 and rotate around the axis of the third gear 508. In summary, the stirring mechanism 5 in this device has a complex stirring trajectory and has the advantage of efficiently stirring the internal liquid of the mounting frame 1.

[0032] Working principle: When using this cooling water dosing equipment, the liquid medicine is stored in the storage tank 2. The connecting pipe 401 is connected to the interior of the cooling water circulation system through the inlet valve 402 and the outlet valve 403. The metering pump 3 pumps the liquid medicine in the storage tank 2 into the interior of the connecting pipe 401 through the inlet pipe 406. During this process, the spring 410 provides elastic force towards the connecting pipe 404, so that when the pressure inside the connecting pipe 401 is too high, the liquid overcomes the elastic force of the spring 410 and enters the interior of the storage shell 407. When the pressure returns to normal, the liquid flows back from the interior of the storage shell 407 into the interior of the connecting pipe 401, thereby achieving the effect of balancing the pressure inside the circulation system. During this process, the one-way valve 405 prevents the cooling water on the inlet pipe 406 side from flowing back, thereby preventing the liquid medicine from flowing into the interior of the storage shell 407.

[0033] The overall operation of the equipment is controlled by the control box 6. The flow meter 411 detects the liquid flow rate inside the connecting pipe 401. The operation of the metering pump 3 is controlled according to the flow data, so as to achieve the purpose of precise dosing according to the cooling water flow rate. The liquid level gauge 9 detects the liquid level inside the storage tank 2, so as to facilitate personnel to replenish the liquid.

[0034] The motor 501 drives the connecting shaft 504 to rotate, which in turn drives the mounting block 505 and the stirring shaft 510 to rotate. During this process, the gear disk 503 drives the first gear 506 to rotate, which in turn drives the third gear 508 to rotate through the second gear 507. Finally, the third gear 508 drives the stirring shaft 510 to rotate through the extension rod 509. In summary, when the motor 501 is running, the stirring shaft 510 will revolve around the axis of the connecting shaft 504 and rotate around the axis of the third gear 508. In summary, the stirring mechanism 5 in this device has a complex stirring trajectory and has the advantage of efficiently stirring the internal liquid of the mounting frame 1.

[0035] The metering pump 3 pumps the liquid medicine inside the storage tank 2 through the pumping pipe 7. The pumping pipe 7 is made of rigid material to ensure that the pumping pipe 7 will not swing with the water flow and to prevent the pumping pipe 7 from being stirred into the interior of the stirring mechanism 5. The filter head 8 prevents impurities inside the liquid medicine from entering the interior of the metering pump 3 through the pumping pipe 7.
