Description

Technical Field

[0001] The present application relates to the technical field of drug dosing, and in particular to a device for controlling drug concentration in industrial circulating cooling water. Background Art

[0002] Industrial circulating cooling water is a water system that is recycled during industrial production to achieve cooling purposes. Industrial circulating cooling water chemicals are added on demand during the operation of the circulating water system. The main purpose is to maintain stable water quality and ensure the efficient and safe operation of the system. Chilled brine corrosion inhibitor is a common industrial circulating cooling water chemical. It is a chemical additive specifically used to slow down or prevent metal corrosion in the chilled brine system.

[0003] The uneven concentration of the frozen brine corrosion inhibitor added in the industrial circulating cooling water circulation system will cause the drug efficacy in some areas of the system to be too strong and in other areas to be insufficient, which will directly affect the overall treatment effect of the system. For example, it may cause scaling or corrosion problems in some areas, while other areas may have side effects due to excessive dosage of the drug. The areas with excessive dosage of the drug not only waste the drug, but also increase the cleaning frequency and maintenance cost of the system. The areas with insufficient dosage of the drug may require additional treatment to make up for it, which ultimately leads to an increase in the overall operating cost. In order to solve the above problems, an industrial circulating cooling water drug concentration control and dosing device is proposed.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-5 This application is described in further detail.

[0023] The embodiment of the present application discloses an industrial circulating cooling water agent concentration control and dosing device. Figure 1-5 A device for controlling and dosing a concentration of a cooling water agent in industrial circulation includes a clamp 1 fixed to a circulating cooling water pipe 101, a detachable mixing chamber 2 provided on the clamp 1, a stirring assembly for uniformly distributing the concentration of the cooling water agent provided in the mixing chamber 2, an outlet pipe 14 for dosing the cooling water agent into the circulating cooling water pipe 101 provided on the mixing chamber 2, and a solenoid valve 9 provided on the outlet pipe 14;

[0024] The stirring assembly includes a motor 6, a stirring shaft 7, and stirring blades 8. The stirring shaft 7 rotates in the mixing chamber 2. The stirring blades 8 are C-shaped and staggeredly fixed on the stirring shaft 7. The motor 6 is fixed on the mixing chamber 2, and the rotor end of the motor 6 is fixed to the stirring shaft 7.

[0025] It should be noted that in order to more effectively ensure the rapid and uniform distribution of cooling water chemicals throughout the system and reduce the problem of localized excessive or low concentrations, dispersed dosing can be performed at multiple key locations in the circulating cooling water system. In a multi-point dosing system, each dosing point may need to be equipped with a different type of mixing chamber 2 based on its specific location in the circulating water system and treatment requirements. The removable mixing chamber 2 can easily adjust the type or position of the mixing chamber 2 based on actual operating results, optimizing the mixing and dispersion of cooling water chemicals.

[0026] It should be further explained that the C-shaped stirring blades 8 can generate strong axial and radial flows, which help the cooling water agent circulate fully in the mixing chamber 2 and improve the mixing uniformity. The stirring blades 8 are staggered and fixed on the stirring shaft 7, which can form a three-dimensional flow pattern for the cooling water agent in the mixing chamber 2. The cooling water agent is fully stirred at different depths and directions, which helps to eliminate the stirring dead angle and improve the overall mixing uniformity.

[0027] By adopting the above technical solution, when in use, start the motor 6 to make the stirring shaft 7 drive the stirring blades 8 thereon to stir the coolant agent in the mixing chamber 2 to make its concentration uniform, then the solenoid valve 2 9 is energized and opened, and an appropriate amount of cooling water agent with uniform concentration is added to the circulating cooling water pipe 101. When it is necessary to clean the agent residue or precipitation in the mixing chamber 2, the mixing chamber 2 can be disassembled and replaced.

[0028] Reference Figure 5 A fixing block 13 is provided at the bottom of the mixing chamber 2, and a fixing groove 15 for the fixing block 13 to pass through is provided on the clamp 1, and the fixing block 13 and the fixing groove 15 are wedge-shaped matched;

[0029] By adopting the above technical solution, the wedge-shaped cooperation between the fixing block 13 and the fixing groove 15 can provide strong supporting force in the vertical and horizontal directions, ensuring that the mixing chamber 2 is stable and does not shift during operation.

[0030] Reference Figure 3 , a water inlet pipe 4 is provided on the mixing chamber 2, the other end of the water inlet pipe 4 is connected to the water inlet end of the circulating cooling water pipe 101, a solenoid valve 3 is provided on the water inlet pipe 4, and a water outlet pipe 14 is located downstream of the water inlet pipe 4, and the solenoid valve 3 and the water outlet pipe 14 are respectively located on both sides of the mixing chamber 2;

[0031] By adopting the above technical solution, the solenoid valve 3 is energized and opened, so that an appropriate amount of water in the circulating cooling water pipe 101 enters the mixing chamber 2 through the water inlet pipe 4, and the concentration of the cooling water agent in the mixing chamber 2 is adjusted. The cooling water agent with uniform concentration flows into the circulating cooling water pipe 101 through the water outlet pipe 14. The positions of the water inlet pipe 4 and the water outlet pipe 14 also play a certain limiting role on the position of the mixing chamber 2.

[0032] Reference Figure 3 , the mixing chamber 2 is provided with a cooling water agent tank 5 which is in communication with the inner cavity of the mixing chamber 2;

[0033] It should be noted that a solenoid valve 3 (not shown) is further provided at the connection between the cooling water agent tank 5 and the mixing chamber 2 to control the dosage of the cooling water agent tank 5 entering the mixing chamber 2;

[0034] By adopting the above technical solution, the cooling water agent tank 5 is allowed to add an appropriate amount of high-concentration cooling water agent into the mixing chamber 2 by switching the electromagnetic valve 3.

[0035] Reference Figure 3 , a second measuring ruler 12 is provided on the mixing chamber 2, and a first measuring ruler 11 is provided on the cooling water tank 5;

[0036] By adopting the above technical solution, the water in the water inlet pipe 4 and the high-concentration cooling water agent in the cooling water agent tank 5 are added into the mixing chamber 2 in the required proportion by referring to the scale indexes of the measuring ruler 2 12 and the measuring ruler 1 11, thereby ensuring that the concentration of the cooling water agent entering the circulating cooling water pipe 101 is appropriate.

[0037] Reference Figure 3 , a one-way valve 10 is provided in the circulating cooling water pipe 101, and the one-way valve 10 is located between the solenoid valve 3 and the water outlet pipe 14;

[0038] By adopting the above technical solution, the setting of the one-way valve 10 prevents the cooling water agent of uniform concentration injected into the circulating cooling water pipe 101 from the outlet pipe 14 from flowing back, thereby ensuring the injection effect of the cooling water agent.

[0039] The implementation principle of the device for controlling the concentration of a chemical dosing device for circulating cooling water of the present application is as follows: when in use, the clamp 1 is fixed to one end of the water inlet of the circulating cooling water pipe 101 by bolts, and then the mixing chamber 2 is fixed to the clamp 1 by the wedge-shaped fit of the fixing block 13 and the fixing groove 15. After the water inlet pipe 4 and the water outlet pipe 14 are connected in sequence, the solenoid valve 13 is energized to open and water enters the mixing chamber 2 through the water inlet pipe 4. The reading of the measuring ruler 12 is observed. When the water reaches the required height, the solenoid valve 3 is de-energized and closed. At this time, the solenoid valve in the cooling water tank 5 is closed. The third switch is turned on, and when the indication of the measuring scale 11 drops to the required position, the solenoid valve 3 is turned off and closed. At this time, the motor 6 is started to make the stirring shaft 7 drive the stirring blade 8 thereon to stir the coolant agent in the mixing chamber 2 to make its concentration uniform. The solenoid valve 2 9 is powered on and opened, and the coolant agent with uniform concentration enters the circulating cooling water pipe 101 through the outlet pipe 14. When it is necessary to clean the agent residue or precipitation in the mixing chamber 2, remove the connection between the water inlet pipe 4 and the outlet pipe 14 and the circulating cooling water pipe 101, and release the wedge-shaped fit between the fixing block 13 and the fixing groove 15.
