Description

TECHNICAL FIELD

[0001] The utility model relates to the field of internal cooling water treatment technology, especially to an internal cooling water quality stabilizing device. BACKGROUND

[0002] The circulating internal cooling water removes the heat generated by the equipment through circulation, ensures the equipment to operate in the normal temperature range, improves the production efficiency and guarantees the stability of the production process, and the internal cooling water quality stability is very important, which relates to the continuity and safety of the machining center production, generally speaking, the water scaling, corrosion and microbial contamination are three major elements of water quality control, and the internal cooling water can be used in the high-tech and high-growth industries such as laser welding, mobile phone screen and shell deep processing cleaning, and the continuity and technical requirements of production are very high, but the internal cooling water is prone to water quality problems due to the water scaling, corrosion and microbial contamination and other factors.

[0003] At present, the industry has no good solution to the above problems, and the direct filling of mixed ion exchange resin and filter core is widely adopted, but the water quality stability is still poor, the internal cooling water is replaced frequently, the production continuity and production efficiency are affected, and the maintenance cost is high.

[0004] Therefore, it is necessary to provide an internal cooling water quality stabilizing device to solve the above technical problems. SUMMARY

[0005] The utility model discloses a kind of internal cooling water quality stabilizing devices, to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model solves the above technical problems by the following scheme: a kind of internal cooling water quality stabilizing device, including internal cooling water tank and water delivery pipe, the inside of the internal cooling water tank is provided with filter bucket, pipeline type ultraviolet sterilizer is connected on the internal cooling water tank by water delivery pipe, the output end of the pipeline type ultraviolet sterilizer is connected with filter by water delivery pipe, the side of the internal cooling water tank is provided with application machining center, the output end of the filter is connected with the input end of application machining center by water delivery pipe, and the internal cooling water output end of the application machining center is returned to the inside of internal cooling water tank by water delivery pipe.

[0007] As a further scheme of the utility model, the top of the filter bucket is provided with filter screen plate.

[0008] As a further scheme of the utility model, the inside of the filter bucket is provided with mixed ion resin.

[0009] As a further embodiment of this utility model, a breather is fixed on the top of the internal cooling water tank, and the output end of the breather is connected to the inside of the internal cooling water tank.

[0010] As a further embodiment of this invention, a water pump is connected between the filter and the application processing center.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] First, when water flows through the mixed ion exchange resin at a certain laminar flow rate, it can efficiently and quickly exchange anions and cations, increasing the water's resistivity and adjusting the water quality to a slightly alkaline state, reducing water corrosion. Second, the internal cooling water flow through the pipeline ultraviolet sterilizer is irradiated by the ultraviolet light emitted at an effective dose of 30 mJ / cm², sufficient to kill most microorganisms in the internal cooling water. Thus, ultraviolet light can effectively control microorganisms in the internal cooling water system, greatly reducing their adhesion ability. Furthermore, the ultraviolet-irradiated internal cooling water flows into the filter, which filters and isolates microorganisms, intercepting them or their remains. Finally, the breather isolates airborne microorganisms and water vapor while simultaneously connecting to the atmosphere, removing carbon dioxide from the air, ensuring the slightly alkaline state of the circulating water, and allowing air to freely enter and exit the upper space of the internal cooling water tank, maintaining atmospheric pressure and providing some heat dissipation. Through the combination of these multiple purification steps, scaling, corrosion, and microbial adhesion in the internal cooling water system are greatly reduced, stabilizing the internal cooling water quality and significantly reducing the frequency of circulating internal cooling water replacement.

[0017] 1. Internal cooling water tank; 2. Pipeline ultraviolet sterilizer; 3. Filter; 4. Breather; 5. Filter barrel; 6. Mixed ion exchange resin; 7. Water supply pipe; 8. Water pump; 9. Application machining center. Detailed Implementation

[0018] The present invention will be further described below with reference to the embodiments.

[0019] Please see Figures 1-2This utility model provides an internal cooling water quality stabilization and regulation device, including an internal cooling water tank 1 and a water supply pipe 7. A filter barrel 5 is fixed inside the internal cooling water tank 1, and a filter screen plate is fixed to the top of the filter barrel 5. The filter screen plate can be made of stainless steel, etc. A pipeline-type ultraviolet sterilizer 2 is connected to the output end of the internal cooling water tank 1 through the water supply pipe 7. A filter 3 is connected to the output end of the pipeline-type ultraviolet sterilizer 2 through the water supply pipe 7. An application processing center 9 is arranged on one side of the internal cooling water tank 1. The output end of the filter 3 is connected to the input end of the application processing center 9 through the water supply pipe 7. The internal cooling water output end of the application processing center 9 returns the internal cooling water to the internal cooling water tank 1 through the water supply pipe 7. The internal cooling water circulates in the system, carrying away heat from the application processing center 9 for heat dissipation and cooling. The internal cooling water tank 1 adopts a completely sealed structure. Cold water systems are typically in a relatively oxygen-deficient environment, where anaerobic bacteria multiply rapidly. Firstly, the internal cold water flow is irradiated through a pipeline-type ultraviolet sterilizer 2. The emitted ultraviolet light uses an effective dose of 30 mJ / cm², sufficient to kill most microorganisms in the internal cold water. This effectively controls microorganisms in the internal cold water system, significantly reducing their adhesion. Secondly, the ultraviolet-irradiated internal cold water flows into a filter 3, which contains a pleated filter element with an absolute filtration precision of 0.45 microns or less. This filter isolates microorganisms, intercepting them or their remains, greatly reducing scaling, corrosion, and microbial adhesion in the internal cold water system. This stabilizes the water quality and significantly reduces the frequency of circulating internal cold water replacement.

[0020] Further as Figure 1 As shown, it is worth noting that the filter tank 5 is equipped with a mixed ion exchange resin 6. In the prior art, the internal cooling water is usually commercially available purified water. This water inevitably has the problems of microorganisms and acidity, i.e., it has a corrosive tendency. The mixed ion exchange resin 6 is composed of a uniform mixture of high-purity hydrogen-type cation exchange resin and hydroxide-type anion exchange resin. When water passes through the mixed ion exchange resin 6 at a certain laminar flow rate, it can efficiently and quickly carry out cation and anion exchange. Anions replace hydroxide ions, and cations replace hydrogen ions. The replaced hydrogen ions and hydroxide ions react almost simultaneously to generate water, thereby increasing the resistivity of the water and adjusting the water quality to weak alkalinity, reducing water corrosion.

[0021] Further as Figure 1 and Figure 2As shown, it is worth noting that a breather 4 is fixed on the top of the internal cooling water tank 1, and the output end of the breather 4 is connected to the inside of the internal cooling water tank 1. If the internal cooling water tank 1 is directly connected to the atmosphere, on the one hand, the carbon dioxide in the air will directly affect the resistivity of the water in the internal cooling water tank 1, and on the other hand, microorganisms in the air will continuously inoculate into the water, causing the microorganisms in the water to multiply continuously. In this case, the water quality deteriorates quickly and needs to be changed frequently. However, the processing center 9 usually does not have time to frequently stop production to change the water. The main function of the breather 4 is to vent the internal cooling water tank 1 to the outside atmosphere, which makes it easier to achieve circulation control. At the same time, the breather 4 is equipped with a 0.22-micron air filter element, which isolates microorganisms and water vapor in the air on the one hand, and connects to the atmosphere on the other hand, removing carbon dioxide from the air to ensure the weak alkalinity of the circulating water. Therefore, by setting the breather 4, the water quality is ensured to remain stable while allowing air to freely enter and exit the upper space of the internal cooling water tank 1, maintaining atmospheric pressure and some heat dissipation, thus ensuring good water quality.

[0022] Further as Figure 1 As shown, it is worth noting that a water pump 8 is installed between the filter 3 and the application processing center 9, and the water pump 8 is connected to the filter 3 and the application processing center 9 through a water supply pipe 7.

[0023] In summary: First, when water flows through the mixed ion exchange resin 6 at a certain laminar flow rate, it can efficiently and rapidly perform cation and anion exchange, increasing the water's resistivity and adjusting the water quality to a slightly alkaline state, thus reducing water corrosion. Second, the pipeline-type ultraviolet sterilizer 2 irradiates the flowing internal cooling water, emitting ultraviolet light at an effective dose of 30 mJ / cm², sufficient to kill most microorganisms in the internal cooling water. Therefore, ultraviolet light can effectively control microorganisms in the internal cooling water system, significantly reducing their adhesion ability. Furthermore, after ultraviolet light... The irradiated internal cooling water flows into filter 3, which filters and isolates microorganisms, thereby intercepting microorganisms or their remains. Finally, the respirator 4 isolates microorganisms and water vapor in the air on the one hand, and connects to the atmosphere on the other hand, removing carbon dioxide from the air, ensuring the weak alkalinity of the circulating water, and allowing air to freely enter and exit the upper space of the internal cooling water tank 1, maintaining atmospheric pressure and some heat dissipation. Through the combination of the above multiple purification steps, the scaling, corrosion and microbial attachment of the internal cooling water system are greatly reduced, the internal cooling water quality is stabilized, and the frequency of internal cooling water replacement is effectively reduced.
