Description

Technical Field

[0001] This utility model relates to the field of cooling water sterilization, and more specifically, to a circulating water descaling and sterilization device. Background Technology

[0002] With the widespread application of industrial and domestic water systems, circulating water is increasingly used in various fields. However, due to the large amount of dissolved calcium, magnesium, and other metal ions in circulating water, scale easily forms during long-term circulation. Scale formation not only reduces the heat exchange efficiency of equipment but can also clog pipes, leading to decreased system operating efficiency and even equipment damage. Furthermore, prolonged water circulation in circulating water systems can breed a large number of bacteria, affecting water quality and adversely impacting both the system and users. Therefore, descaling and sterilization treatment of circulating water has become an important technical challenge in this field.

[0003] Existing circulating water treatment equipment typically removes scale by adding chemical descaling agents or through physical filtration, but this approach presents several technical challenges. Firstly, the mixing efficiency of descaling agents with water in existing equipment is low, easily leading to insufficient agent utilization or uneven mixing, thus affecting the descaling effect. Secondly, many existing systems lack effective filtration devices, making it difficult to thoroughly remove tiny scale particles from the circulating water, thereby impacting water quality. Furthermore, some equipment lacks precise control over the addition, mixing, and drainage of descaling agents during operation, increasing the difficulty of use and maintenance costs.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] This utility model provides a circulating water descaling and sterilization device. By setting a stirring mechanism inside the mixing tank, it achieves efficient mixing of circulating water and descaling agent. The stirring blades and drive motor work together to enable the descaling agent to fully react with calcium and magnesium ions in the circulating water through complexation or chelation reactions, preventing the formation of large scale particles and decomposing them into tiny scale particles for easy filtration. The design structure of the mixing tank ensures that the descaling agent and water are mixed evenly according to the set ratio, improving the descaling efficiency and overcoming the problem of poor descaling effect caused by uneven mixing in the prior art.

[0018] By incorporating an inlet pipe, an injection bend, and a descaling agent storage tank into the mixing tank, along with a combination of a movable plate, a fixing bolt, and a spring, the equipment can precisely control the inflow of circulating water and descaling agent. The movable plate is designed with a spring providing reset power, enabling the first and second plugs to open and close synchronously during the circulating water flow, thus ensuring accurate mixing ratios of circulating water and descaling agent. This design effectively solves the problem of difficulty in controlling the amount of descaling agent added in existing technologies, improving the safety and stability of the system operation.

[0019] The equipment features a filter cartridge at the end of the outlet pipe, which performs secondary filtration of tiny scale particles in the circulating water using a filter screen. The replaceable filter screen design allows for the selection of filter cloth or ultrafiltration membrane based on different water quality environments, thus meeting the filtration needs of various scenarios. Simultaneously, the inclusion of a drain pipe and sealing cap enables rapid cleaning of deposits inside the filter cartridge, ensuring continuous and efficient operation of the equipment. This structure improves upon the poor filtration performance of existing technologies, effectively enhancing water purification.

[0020] This utility model has a compact overall structure and is easy to operate. By setting up mounting blocks to provide stable support for the mixing tank, the equipment remains stable during operation, reducing the impact of vibration or displacement on the system. The functional modules of the equipment are reasonably designed, fully considering the maintenance and cleaning needs in actual use, significantly reducing the cost of use and maintenance difficulty, and improving the service life and reliability of the equipment.

[0028] Example 1:

[0029] Please see Figure 1 , Figure 2 and Figure 5 As shown, a circulating water descaling and sterilization device includes a mixing tank 1 and a descaling agent storage tank 4. The mixing tank 1 is hollow inside and is used to contain the mixing of circulating water and descaling agent for reaction.

[0030] The mixing tank 1 is equipped with a stirring mechanism 3 for thoroughly mixing the circulating water and the descaling agent. The descaling agent storage tank 4 is positioned above the inlet pipe 12, allowing the molten descaling agent to flow smoothly into the mixing tank 1 under gravity. An injection bend 41 is connected to the bottom of the descaling agent storage tank 4; the bend design of the injection bend 41 ensures smooth flow of the molten descaling agent. The end of the injection bend 41 connects to the upper part of the mixing tank 1, allowing the descaling agent to be directly injected into the mixing tank 1. A fixing bolt 14 is installed on the inner wall of the mixing tank 1 to support and guide the movable plate. The movement of 6; the fixing bolt 14 is placed between the water inlet pipe 12 and the injection bend 41 to adjust the on / off state of the water inlet pipe 12 and the injection bend 41; a movable plate 6 is slidably installed on the surface of the water inlet pipe 12, and the movable plate 6 can move along the axial direction of the fixing bolt 14; a first plug 61 adapted to the flow channel of the water inlet pipe 12 is provided below one side surface of the movable plate 6 to seal the water inlet pipe 12; a second plug 62 adapted to the flow channel of the injection bend 41 is provided above one side surface of the movable plate 6 to seal the injection bend 41, so as to realize synchronous opening or closing.

[0031] refer to Figure 2 and Figure 5 As shown, a limiting plate 15 is provided at the end of the fixing bolt 14. The limiting plate 15 is used to limit the range of movement of the movable plate 6 and ensure the stability of the movement. A spring 5 is sleeved on the surface of the fixing bolt 14. The spring 5 is placed between the movable plate 6 and the fixing bolt 14 to provide a reset elastic force to ensure that the movable plate 6 can return to the initial position when there is no circulating water. The elastic design of the spring 5 can adjust the movement force of the movable plate 6 as needed.

[0032] refer to Figure 2 and Figure 3 As shown, the stirring mechanism 3 includes a sealing plate 31 fixed to the top of the mixing tank 1; a drive motor 32 is installed on the upper surface of the sealing plate 31, which serves as the power source for the stirring mechanism 3, and its output end is connected to a rotating shaft 33; the rotating shaft 33 is vertically placed inside the mixing tank 1 and is used to transmit the power of the drive motor 32 to the stirring blades 34; the bottom of the rotating shaft 33 is equipped with stirring blades 34, which are used to fully stir the circulating water and descaling agent inside the mixing tank 1 to ensure that they are mixed evenly and that the descaling agent fully undergoes complexation or chelation reaction with the calcium and magnesium ions in the water.

[0033] refer to Figure 2 and Figure 4As shown, the filter cartridge 2 is connected to the outlet pipe 13 to ensure that the circulating water can smoothly enter the filter cartridge 2 after descaling treatment; a drain pipe 21 is provided on the lower side of one side of the filter cartridge 2 to discharge the wastewater collected during the filtration process; the bottom of the filter cartridge 2 is open for easy maintenance and cleaning; a sealing cap 22 is screwed and sealed at the bottom of the filter cartridge 2 to prevent leakage at the bottom of the filter cartridge 2; a knob 23 is provided at the center of the lower surface of the sealing cap 22, which can be used to easily install and remove the sealing cap 22; a filter screen cylinder 24 is installed on the top of the sealing cap 22, which wraps the inner flow channel of the filter cartridge 2 to filter out small scale particles and other particulate foreign objects in the circulating water; the filter screen cylinder 24 can be selected with filter screens or ultrafiltration membranes of different pore sizes as needed to achieve the best filtration effect.

[0034] refer to Figure 1 As shown, mounting blocks 11 are symmetrically arranged on the side surface of the mixing tank 1 away from the water inlet pipe 12. The mounting blocks 11 are used to support and fix the structure of the mixing tank 1 to ensure the stability and reliability of the equipment during operation.

[0035] Working principle: Descaling agent melt is injected into the descaling agent storage tank 4. The descaling agent and water are mixed in a certain proportion to form the descaling agent melt. Due to the presence of spring 5, the movable plate 6 has an outward force. At this time, the second plug 62 blocks and seals the injection bend 41, and the first plug 61 blocks and seals the flow channel inside the water inlet pipe 12. Then, the circulating water pipe is connected to the water inlet pipe 12, and the water flows into the mixing tank 1 through the water inlet pipe 12. When the circulating water enters, it can push the movable plate 6 out, so that the movable plate 6 moves along the axis of the fixing bolt 14 towards the central axis of the mixing tank 1. At this time, the second plug 62 is released from the seal on the injection bend 41, and the descaling agent melt inside the descaling agent storage tank 4 will flow into the mixing tank 1, so that the descaling agent and circulating water flow into the mixing tank 1 in equal proportion, and can be opened or closed at the same time.

[0036] Then, the stirring mechanism 3 is activated to mix the flowing circulating water and descaling agent through the stirring blades 34. The descaling agent undergoes complexation or chelation reactions with calcium, magnesium and other ions in the water, preventing them from forming scale deposits, or dispersing the already formed small scale particles in the water, making it less likely to aggregate into large scale blocks. The circulating water will flow into the filter cylinder 2 through the outlet pipe 13. When entering the filter cylinder 2, it will flow through the filter screen cylinder 24 to filter the small scale particles in the circulating water. The water will then be discharged through the drain pipe 21. The filter screen cylinder 24 can also be lined with filter cloth. In special environments, a 0.01-0.1 micron ultrafiltration membrane can also be laid for filtration.

[0037] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
