Description

Technical Field

[0002] Circulating water often contains a large amount of calcium, magnesium and other ions. Under certain conditions, scale will form and adhere to the inner wall of pipes and equipment, reducing heat exchange efficiency, increasing energy consumption, and even damaging equipment; various bacteria and algae are also easy to breed in circulating water. These microorganisms will not only affect the water quality, but also block pipes and equipment, reducing the operating efficiency of the system. During the use of circulating water, the circulating water is usually hydrolyzed by a circulating water automatic hydrolysis device. It can kill bacteria and algae in the circulating water by producing specific chemicals or physical effects to keep the water clean, and promote the hydrolysis reaction of calcium and magnesium ions in the water to form substances that are not easy to precipitate, thereby effectively preventing the occurrence of scaling. Nowadays, the circulating water automatic hydrolysis device is usually composed of a hydrolysis reactor, a control system, a dosing system and other parts. The hydrolysis reactor is the core component to promote the hydrolysis reaction of water. The control system can automatically monitor and adjust the operating parameters of the device to ensure its stable operation. The dosing system adds specific agents to the circulating water as needed to enhance the hydrolysis effect.

[0032] In this embodiment, the drug dispensing mechanism includes a medicine tank 16, a tank cover 17, a drug outlet pipe 18 and a baffle plate 19. The medicine tank 16 is fixedly installed on the top of the box body 1. A drug discharge port is provided on the top of the medicine tank 16. The tank cover 17 is threadedly installed in the drug discharge port. The drug outlet pipe 18 is fixedly installed at the bottom of the medicine tank 16. The bottom end of the drug outlet pipe 18 extends into the box body 1. The baffle plate 19 is fixedly mounted on the vertical shaft 7 and is located in the box body 1.

[0035] In this embodiment, the pressure relief mechanism includes a pressure relief cylinder 21, a piston 22, a spring 23, a drain pipe 26 and a guide column 28. The pressure relief cylinder 21 is fixedly installed at the bottom of the box body 1. The top of the pressure relief cylinder 21 is an open structure and is connected to the inside of the box body 1. The piston 22 is arranged in the pressure relief cylinder 21. The piston 22 is in sliding and sealing contact with the inner wall of the pressure relief cylinder 21. The bottom end of the spring 23 is fixedly connected to the bottom inner wall of the pressure relief cylinder 21. The top of the spring 23 is fixedly connected to the bottom of the piston 22. An L-shaped water flow hole 24 is opened on the top of the piston 22. A mounting hole 25 is opened on the right side wall of the pressure relief cylinder 21. The left end of the drain pipe 26 is fixedly installed in the mounting hole 25. The L-shaped water flow hole 24 is located just above the mounting hole 25. The guide column 28 is fixedly mounted on the bottom inner wall of the pressure relief cylinder 21, and a guide groove 29 is provided at the bottom of the piston 22. The top end of the guide column 28 is slidably mounted in the guide groove 29. The arrangement of the guide column 28 and the guide groove 29 ensures the stable movement of the piston 22 in the pressure relief cylinder 21. When the water pressure in the box body 1 exceeds the elastic force of the spring 23, the piston 22 will move downward, so that the L-shaped water flow hole 24 is connected to the drain pipe 26, and the excess water is discharged from the drain pipe 26, thereby reducing the pressure inside the box body 1, which helps to protect the equipment and pipelines and prevent rupture or damage due to excessive pressure. It should be supplemented that the end of the drain pipe 26 away from the pressure relief cylinder 21 is connected to an external water receiving container.

[0036] In this embodiment, an L-shaped baffle rod 27 is fixedly installed on the bottom inner wall of the pressure relief cylinder 21, and the top of the piston 22 extends outside the pressure relief cylinder 21 and contacts the L-shaped baffle rod 27. The L-shaped baffle rod 27 can limit the maximum rising stroke of the piston 22 to prevent the piston 22 from excessive movement and damaging the equipment.

[0037] In this embodiment, an inspection port is opened on the front side of the box body 1, and an inspection door 30 is detachably installed and fixed on the front outer wall of the box body 1. The inspection door 30 is adapted to the inspection port, which facilitates the maintenance and overhaul of the equipment. The staff can inspect, clean and repair the inside of the equipment through the inspection port, thereby improving the maintainability of the equipment.

[0038] In this embodiment, it should be noted that the motor 11 and the ultraviolet sterilization lamp 15 can be purchased on the market. The motor 11 uses a low-speed motor. The motor 11 and the ultraviolet sterilization lamp 15 are equipped with a power supply. Their circuit connection method and control method are mature technologies in this field, so they will not be described in detail in this article.

[0039] Through the above structure, the circulating water automatic hydrolysis device provided by the present application has efficient hydrolysis processing capacity when in use, can accurately control the dosing, improves the quality of the circulating water automatic hydrolysis processing, and has a safe and reliable pressure relief function, which helps to protect the equipment and pipelines from rupture or damage due to excessive pressure, and can provide a strong guarantee for the stable operation of the circulating water system. During the specific operation, the circulating water first enters the box 1 on the left side through the circulating water input pipe 2, controls the motor 11 to run and turns on the ultraviolet sterilization lamp 15. At this time, the motor 1 1 drives the main gear 12 to rotate, and the meshing transmission effect of the main gear 12 and the sub-gear 13, and the transmission effect of the two pulleys 9 and the belt 10, can make the two vertical shafts 7 rotate at the same time, and the multiple stirring blades 8 rotate with the vertical shaft 7. The two vertical shafts 7 drive the corresponding baffle plates 19 to rotate. When the baffle plate 19 on the left rotates, the medicine leakage hole 20 on the left baffle plate 19 and the medicine outlet pipe 18 on the left are intermittently aligned, and the scale inhibitor in the left medicine tank 16 can intermittently flow into the left box 1 and mix with the circulating water. The rotation of the stirring blade 8 inside can fully stir and mix the scale inhibitor and the circulating water, which can promote the hydrolysis reaction of calcium, magnesium and other ions in the water to form substances that are not easy to precipitate, thereby effectively preventing the occurrence of scaling. The circulating water in the left box 1 can pass through the activated carbon filter plate 6 and pass through the channel 5 to enter the right box 1 after the initial hydrolysis treatment. The activated carbon filter plate 6 can effectively remove impurities and organic matter in the circulating water. When the baffle plate 19 on the right side rotates, the medicine leakage hole 20 on the baffle plate 19 on the right side and the medicine outlet pipe 1 on the right side are connected. 8 intermittently aligned, the nano titanium dioxide catalyst in the right medicine tank 16 can intermittently flow into the right box 1 and mix with the circulating water. By utilizing the rotation of the stirring blade 8 in the right box 1, the nano titanium dioxide catalyst and the circulating water can be fully stirred and mixed evenly. Under the ultraviolet light emitted by the ultraviolet sterilization lamp 15, the organic matter in the water can be fully and effectively decomposed, the pollutants in the circulating water can be effectively degraded, and the bacteria can be killed to achieve the effect of disinfection. Finally, the circulating water treated by secondary hydrolysis is discharged through the circulating water output pipe 3; During the process of automatic hydrolysis treatment of circulating water, when the circulating water pressure inside the box body 1 is too high and exceeds the set value, the water pressure can be used to apply a downward force to the piston 22, which can overcome the elastic force of the spring 23 and push the piston 22 downward. When the L-shaped water flow hole 24 on the piston 22 moves down to align with the mounting hole 25, the circulating water will be discharged from the drain pipe 26 through the L-shaped water flow hole 24 and the mounting hole 25 in turn, reducing the pressure inside the box body 1. When the pressure inside the box body 1 stabilizes at a suitable value, under the action of the rebound force of the spring 23, the piston 22 can be pushed upward to return to its position and conflict with the L-shaped stop rod 27. At this time, the L-shaped water flow hole 24 and the mounting hole 25 are no longer connected, and the circulating water will no longer flow out of the drain pipe 26, thereby achieving the purpose of automatic pressure relief, protecting equipment and pipelines from rupture or damage due to excessive pressure.
