Description

Technical Field

[0001] This utility model relates to the technical field of production equipment in the sugar industry, specifically a novel circulating water quality adjustment device for production. Background Technology

[0002] In the sugar production process, the water quality of circulating cooling water is particularly important. Currently, some sugar factories monitor water quality mainly by manually taking samples periodically for testing to further determine the water quality. Water quality is also adjusted by manually adding bactericides and scale inhibitors. While this method effectively controls and monitors water quality, it requires significant manpower and resources, is labor-intensive, cannot provide real-time monitoring, and exhibits a delay in responding to and adjusting water quality conditions. Therefore, the previous methods for monitoring and adjusting circulating water quality cannot adequately meet current needs. A new type of circulating water quality adjustment device for production is required to help achieve the aforementioned functions.

[0003] Patent document CN222108974U discloses a water quality adjustment device for a small-scale recirculating aquaculture system. It states that "belonging to the field of aquaculture technology, the filter chamber has a quartz sand filter layer and a biologically active filler layer arranged sequentially from top to bottom. A water spray pipe is located at the top of the filter chamber, connected to a guide pipe. The guide pipe, rubber hose, and outlet of the aerator pump are connected sequentially. The inlet, outer pipe, and inner pipe of the aerator pump are connected sequentially. The inner wall of the outer pipe has grooves on both sides, and spring plates are fixedly connected to both sides of the outer wall of the inner pipe, slidingly engaging with the grooves. The aerator pump interface of the three-way aerator connector is connected to one side of the aerator pump. The air inlet of the three-way aerator connector is connected to an aerator flow regulator via a hose, and the air outlet of the three-way aerator connector is used to discharge air into the aquaculture water. This device has filtration and pest removal functions, increases beneficial microorganisms in the water, improves water quality, enhances the practicality of the device, increases safety and environmental friendliness, and simplifies the device structure."

[0004] However, the water quality regulation device for a small-scale recirculating aquaculture system mentioned in the above-mentioned literature mainly focuses on increasing safety and environmental protection, simplifying the device structure, but it is not convenient for automatic water quality detection and automatic dosing.

[0005] Therefore, it is necessary to develop an automated mechanism that can automatically detect water quality and automatically add chemicals. Utility Model Content

[0006] The purpose of this utility model is to provide a new type of circulating water quality conditioning device for production, so as to solve the technical problem mentioned in the background art of enabling the circulating water quality conditioning device to have an automatic detection function.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a novel circulating water quality adjustment device for production, comprising: a circulating water cooling tower, a mounting plate and a circulating water pump, wherein the outer wall of the circulating water cooling tower is provided with an automatic mechanism, which is used for automatically detecting water quality and automatically adding chemicals;

[0008] The automatic mechanism includes an automatic circulating water detection device, a DCS central control system, a scale inhibitor buffer tank, and a bactericide buffer tank. A plate heat exchanger is installed on the outer wall of the mounting plate. The circulating water cooling tower is located on the outer wall of the mounting plate. The automatic circulating water detection device is installed on the outer wall of the mounting plate. A DCS central control system is installed on the outer wall of the inlet end of the automatic circulating water detection device. The scale inhibitor buffer tank and the bactericide buffer tank are installed on the outer wall of the mounting plate. Automatic control valves are installed at the bottom of both the scale inhibitor buffer tank and the bactericide buffer tank. A dosing pump is installed on the outer wall of the mounting plate. A circulating water pump is installed on the outer wall of the mounting plate. A chemical supply pipe is installed at the outlet end of the chemical supply pump, and one end of the chemical supply pipe extends into the interior of the circulating water cooling tower.

[0009] Preferably, the inlet of the automatic detection circulating water device extends into the interior of the plate heat exchanger and the outlet extends into the interior of the drug supply pipeline; the inlet of the dosing pump extends into the interior of the automatic control valve; the inlet of the circulating water pump extends into the interior of the circulating water cooling tower and the outlet extends into the interior of the plate heat exchanger.

[0010] Preferably, the inner wall of the circulating water cooling tower is provided with a mixing mechanism, which is used to assist the automatic mechanism in mixing the medicine more evenly.

[0011] Preferably, the mixing mechanism includes a mixing motor and a mixing shaft. The mixing motor is located at the top of the circulating water cooling tower. An assembly plate is installed at the output end of the mixing motor. An assembly screw groove is provided on the outer wall of the assembly plate. An assembly screw is provided on the inner wall of the assembly screw groove. A mixing shaft is installed at the bottom of the assembly screw. A rotation anti-slip block is installed at the bottom of the mixing shaft.

[0012] Preferably, the outer wall of the circulating water cooling tower is fitted with hinges, and the outer wall of the hinges is fitted with an inspection door.

[0013] Preferably, the inner wall of the circulating water cooling tower is provided with a maintenance groove.

[0014] Preferably, the outer wall of the circulating water cooling tower is provided with a locking screw groove, and the outer wall of the inspection door is equipped with a locking screw, with one end of the locking screw extending into the interior of the locking screw groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model features an automatic mechanism that automatically detects water quality and adds chemicals. The circulating water first enters a cooling tower for cooling, serving as the starting point to lower the water temperature for subsequent reuse. The cooled circulating water then flows out of the cooling tower and into a plate heat exchanger for heat exchange to meet the cooling requirements of the production process. The cooled circulating water then flows out of the heat exchanger outlet. During this process, the automatic circulating water detection device monitors the water quality in real time, including key indicators such as impurities, pH value, and hardness. This device feeds back the detected water quality information to the DCS central control system in real time. The DCS central control system intelligently analyzes the received water quality data and determines whether scale inhibitors or bactericides need to be added to adjust the water quality. If so, the DCS... The control system determines that chemicals need to be added. It controls the automatic valve to open, allowing the scale inhibitor or bactericide to flow out from the corresponding buffer tank (scale inhibitor buffer tank, bactericide buffer tank). The dosing pump provides power to accurately add the chemicals to the circulating water return pipe, where they are fully mixed with the circulating water. The circulating water with added chemicals continues to circulate in the device under the action of the circulating water pump. After a period of mixing and adjustment, the water quality of the circulating water will gradually stabilize and meet the requirements of the production process. The regulated circulating water re-enters the circulating water cooling tower to start a new cycle. Throughout the entire circulation process, the automatic detection circulating water device continuously monitors the water quality and feeds the data back to the DCS central control system so that the amount of chemicals added can be adjusted in a timely manner to ensure that the circulating water quality is always kept at the optimal level.

[0017] 2. This utility model, by installing a mixing mechanism, assists the automatic mechanism in achieving more uniform mixing of the medicine. Existing models lack an auxiliary function to ensure thorough mixing of the medicine and circulating water when adding medicine to the circulating water, thus requiring improvement. When the circulating water is first added with medicine and circulates into the cooling tower, the mixing motor drives the mixing shaft to rotate, thus fully mixing the medicine and circulating water, facilitating the continued flow of circulating water for further testing. Simultaneously, when the mixing shaft needs to be inspected and disassembled, the locking screw is removed from the locking screw groove, and then the inspection door is opened through the inspection slot via the hinge. The anti-slip slider is then manually rotated to twist the mixing shaft. The mixing motor has a self-locking function when it stops working, allowing the assembly screw to be removed from the assembly screw groove, thus enabling the mixing shaft to be disassembled, inspected, or replaced.

Therefore, previous methods for monitoring and adjusting circulating water quality cannot adequately meet current needs and require improvement. Circulating water first enters the circulating water cooling tower 1 for cooling treatment. This is the starting point of the circulating water system, used to lower the water temperature for subsequent circulation. The cooled circulating water then flows out of the cooling tower and enters the plate heat exchanger 4 for heat exchange to meet the cooling requirements of the production process. The heat-exchanged circulating water flows out from the heat exchanger outlet. At this point, the automatic circulating water detection device 2 monitors the water quality in real time.

It feeds back the detected water quality information to the DCS central control system 3 in real time. The DCS central control system 3 performs intelligent analysis based on the received water quality data and determines whether scale inhibitors or bactericides need to be added to adjust the water quality. If the DCS central control system 3 determines that chemicals need to be added, it controls the automatic valve 7 to open, allowing the scale inhibitor or bactericide to flow from the corresponding buffer tanks (scale inhibitor buffer tank 5, bactericide buffer tank 6). The dosing pump 8 provides power to accurately add the chemicals to the circulating water return pipe, ensuring thorough mixing with the circulating water.

The existing system, when adding chemicals to circulating water, lacks an auxiliary function to ensure thorough mixing of the chemicals and circulating water. Therefore, this needs to be improved. When the circulating water is first added with chemicals and circulates into the circulating water cooling tower 1, the mixing motor 11 drives the mixing shaft 15 to rotate, thus fully mixing the chemicals and circulating water. This facilitates the continued flow of circulating water for further testing. When the mixing shaft 15 needs to be inspected and disassembled, the locking screw 21 is removed from the locking screw groove 20. Then, the inspection door 18 is opened through the inspection slot 19 via the hinge 17. The anti-slip slider 16 is then manually rotated to twist the mixing shaft 15.

The mixing shaft 15 can then be disassembled, inspected, or replaced.

[0028] Working principle: Currently, some sugar factories monitor water quality primarily through regular manual sampling and testing to determine water quality conditions. Water quality is adjusted by manually adding bactericides and scale inhibitors. While this method effectively controls and monitors water quality, it requires significant manpower and resources, is labor-intensive, and cannot provide real-time monitoring. There is a delay in responding to and adjusting water quality conditions. Therefore, the existing methods for monitoring and adjusting circulating water quality cannot adequately meet current needs and require improvement. The circulating water first enters the circulating water cooling tower 1 for cooling treatment. This is the starting point of the circulating water system, used to lower the water temperature for subsequent recycling. The cooled circulating water... The water flows out of the cooling tower and enters the plate heat exchanger 4 for heat exchange to meet the cooling requirements of the production process. After heat exchange, the circulating water flows out from the heat exchanger outlet. At this time, the automatic circulating water detection device 2 will monitor the water quality in real time, including monitoring key indicators such as impurities, pH value, and hardness. The automatic circulating water detection device 2 will feed back the detected water quality information to the DCS central control system 3 in real time. The DCS central control system 3 will perform intelligent analysis based on the received water quality data and determine whether it is necessary to add scale inhibitors or bactericides to adjust the water quality. If the DCS central control system 3 determines that it is necessary to add agents, it will control the automatic control valve 7 to open, so that the scale inhibitor or bactericide is released from the corresponding buffer tank (scale inhibitor buffer tank 5, bactericide buffer tank 6). The chemical flows out of tank 6), and the dosing pump 8 provides power to accurately add the chemical to the circulating water return pipe, mixing it thoroughly with the circulating water. The dosing water, now with the added chemical, continues to circulate within the system under the action of the circulating water pump 9. After a period of mixing and adjustment, the water quality gradually stabilizes, meeting the requirements of the production process. The adjusted circulating water then re-enters the circulating water cooling tower 1 to begin a new cycle. Throughout the entire circulation process, the automatic circulating water detection device 2 continuously monitors the water quality and feeds the data back to the DCS central control system 3, allowing for timely adjustments to the chemical dosage to ensure the circulating water quality remains at its optimal state. Currently, there is no auxiliary system for adding chemicals to the circulating water. The auxiliary function ensures that the medicine and circulating water are fully mixed, so this needs to be improved. When the circulating water is first added to the medicine and circulates into the cooling tower 1, the mixing motor 11 drives the mixing shaft 15 to rotate, which fully mixes the medicine and circulating water, thus facilitating the continued circulation of the circulating water for testing. When the mixing shaft 15 needs to be inspected and disassembled, the locking screw 21 is moved out of the locking screw groove 20, and then the inspection door 18 is opened through the inspection groove 19 via the hinge 17. Then, the anti-slip block 16 is manually rotated to twist the mixing shaft 15. The mixing motor 11 has a self-locking function when it stops working, which allows the assembly screw 14 to be moved out of the assembly screw groove 13, so that the mixing shaft 15 can be disassembled, inspected, or replaced.
