Description

Technical Field

[0001] This utility model relates to the field of water resource recycling technology, specifically an overpressure drainage recovery device. Background Technology

[0002] Water recycling refers to the process of treating and purifying used water (such as industrial wastewater and domestic sewage) through human intervention and then reusing it in production or domestic systems, thus achieving multiple uses of water resources. This process not only includes wastewater reuse but also involves improving water resource utilization efficiency and reducing over-reliance on natural water bodies through water-saving technologies and ecological restoration.

[0003] In the industrial silicon production process, the temperature and composition of demineralized water change after a large amount of water is used. Trace impurities in the water are difficult to remove effectively, and external trace impurities alter the physical properties of the water. As a result, when the recycled water is reinjected into the circulation system, it may cause scaling and corrosion, affecting the system's performance and service life. To address these issues, we provide an overpressure drainage and recovery device. Utility Model Content

[0004] The purpose of this invention is to provide an overpressure drainage recovery device to solve the problems raised in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an overpressure drainage and recovery device, comprising an overpressure drainage pipe and a demineralized water tank, wherein the overpressure drainage pipe is fixedly connected to a water storage tank, the bottom end of the water storage tank is fixedly connected to a power water pump, the output end of the power water pump is fixedly connected to a connecting pipe, the other end of the connecting pipe is fixedly connected to a water tank cover plate adapted to the demineralized water tank, and a purification block is provided inside the demineralized water tank.

[0006] Preferably, a first water level probe and a second water level probe are fixedly connected inside the water storage tank. The first water level probe is located at the lower end of the water storage tank, and the second water level probe is located at the upper end of the water storage tank. When the water level is higher than the second water level probe, the power water pump is started to transport water to the demineralized water tank. When the water level drops below the first water level probe, the staff is notified in time to check for equipment leaks and avoid the power water pump running dry, which could damage the equipment.

[0007] Preferably, the water tank cover is snapped into the demineralized water tank, and the water tank cover is connected to the demineralized water tank by bolts. A shut-off valve is fixedly connected to the surface of the connecting pipe. The water tank cover seals the demineralized water tank and facilitates opening the demineralized water tank for maintenance and replacement of its internal mechanisms.

[0008] Preferably, a water quality detector is fixedly connected inside the demineralized water tank, a third water level probe is fixedly connected to the bottom of the demineralized water tank, and a fourth water level probe is fixedly connected to the middle of the demineralized water tank. The water quality detector is used to monitor the treated water resources inside the demineralized water tank, and if the value exceeds the standard, the staff will be notified in time to replace and maintain the purification block.

[0009] Preferably, a filter box is slidably connected inside the demineralized water tank, and the purification block is fixedly connected to the filter box. A handle groove is provided at the top of the filter box. The purification block is fixed through the filter box, thereby preventing the discharged water from directly entering the bottom of the demineralized water tank and improving the impurity filtration effect.

[0010] Preferably, the demineralized water tank is internally fixedly connected with a support ring, and the filter box is snapped into the support ring. The support ring fixes and seals the filter box, thereby preventing gaps between the purification block and the demineralized water tank and improving the filtration and purification effect of the purification block on the water quality.

[0011] Preferably, the bottom of the demineralized water tank is fixedly connected to a circulating water pipe, and the surface of the circulating water pipe is fixedly connected to a solenoid valve. When the solenoid valve is opened, the water resources inside the demineralized water tank enter the water circulation system through the circulating water pipe for secondary utilization of the water resources.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When the equipment pressure is too high, this application will drain the water through the overpressure drainage pipe to reduce the pressure. The water discharged from the overpressure drainage pipe will be stored in a water storage tank. When there is a lot of water in the water storage tank, the water will be transported to the demineralized water tank through a power water pump and connecting pipe. The discharged water will be filtered and desalinated by the purification block to ensure that the water quality meets the process requirements of the circulation system. This will achieve efficient recycling of water resources, reduce production costs, reduce dependence on fresh water resources, and improve the stability and economy of production.

[0014] 2. This application uses a first water level probe and a second water level probe to limit the water level inside the storage tank. When the water level is higher than the second water level probe, the power water pump is started to transport water into the demineralized water tank. When the water level drops below the first water level probe, staff are notified in a timely manner to check for leaks in the equipment, preventing the power water pump from running dry and causing equipment damage, and extending the service life of the water pump. The demineralized water tank is sealed by a water tank cover, and the tank can be easily opened for maintenance and replacement of internal mechanisms. A shut-off valve prevents backflow of water in the connecting pipes, improving the stability of equipment operation. A filter box fixes the purification block, thereby preventing discharged water from directly entering the bottom of the demineralized water tank and improving the impurity filtration effect.

[0015] 3. This application uses a support ring to fix and seal the filter box, improving the absence of gaps between the purification block and the demineralized water tank and enhancing the filtration and purification effect of the purification block. A water quality detector monitors the treated water inside the demineralized water tank. If the reading exceeds the standard, staff are promptly notified to replace and maintain the purification block. Third and fourth water level probes monitor the water level inside the demineralized water tank. When the water level is below the third water level probe, the solenoid valve closes, storing the water inside the demineralized water tank. When the water level exceeds the fourth water level probe, the solenoid valve opens, allowing the water inside the demineralized water tank to enter the water circulation system through the circulating water pipe for secondary utilization.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 - Figure 4As shown, this utility model provides a technical solution for an overpressure drainage recovery device, including an overpressure drainage pipe 1 and a demineralized water tank 4. The overpressure drainage pipe 1 is fixedly connected to a water storage tank 2. The furnace body and the main outlet pipe of the furnace variable circulation pump are also fixedly connected to the overpressure drainage pipe 1. All the pipes of the overpressure drainage outlet are connected in series through a reasonable layout so that the overpressure drainage can be collected into the water storage tank 2. When the equipment is running, in order to maintain the pressure balance of the pipe and the equipment, the overpressure drainage pipe 1 will be drained to reduce the pressure, and the water resources discharged from the overpressure drainage pipe 1 will be stored in the water storage tank 2.

[0023] The water storage tank 2 is internally fixedly connected to a first water level probe 15 and a second water level probe 16. The first water level probe 15 is located at the lower end of the water storage tank 2, and the second water level probe 16 is located at the upper end of the water storage tank 2. The water level inside the water storage tank 2 is limited by the first water level probe 15 and the second water level probe 16. When the water level is higher than the second water level probe 16, the power water pump 3 is started to transport water into the demineralized water tank 4. When the water level drops below the first water level probe 15, the staff is notified in time to check for equipment leaks, avoid the power water pump 3 running dry and causing equipment damage, and improve the service life of the water pump.

[0024] A power water pump 3 is fixedly connected to the bottom of the water storage tank 2. A connecting pipe 6 is fixedly connected to the output end of the power water pump 3. A water tank cover 5 that is compatible with the demineralized water tank 4 is fixedly connected to the other end of the connecting pipe 6. A purification block 12 is installed inside the demineralized water tank 4. When there is a lot of water in the water storage tank 2, water is transported to the demineralized water tank 4 through the power water pump 3 and the connecting pipe 6. The purification block 12 filters and desalinates the discharged water, so that the water quality meets the process requirements of the circulation system, realizes the efficient recycling of water resources, reduces production costs, reduces dependence on fresh water resources, and improves the stability and economy of production.

[0025] The water tank cover 5 is snapped into the demineralized water tank 4, and the water tank cover 5 is connected to the demineralized water tank 4 by bolts. A shut-off valve 7 is fixedly connected to the surface of the connecting pipe 6. The water tank cover 5 seals the demineralized water tank 4 to prevent external impurities from contaminating the water resources, and facilitates the opening of the demineralized water tank 4 for maintenance and replacement of the internal mechanism. The shut-off valve 7 prevents backflow of water inside the connecting pipe 6, thereby improving the stability of equipment operation.

[0026] The demineralized water tank 4 has a filter box 11 slidably connected inside, and the purification block 12 is fixedly connected to the filter box 11. The top of the filter box 11 has a handle groove 13. The filter box 11 is used to fix the purification block 12, thereby preventing the discharged water from directly entering the bottom of the demineralized water tank 4, improving the impurity filtration effect. The handle groove 13 makes it easy to take out and put in the filter box 11, reducing the maintenance difficulty of the purification block 12 and improving the equipment maintenance efficiency.

[0027] The demineralized water tank 4 is internally fixedly connected with a support ring 10, and the filter box 11 is snapped into the support ring 10. The support ring 10 fixes and seals the filter box 11, thereby preventing gaps between the purification block 12 and the demineralized water tank 4 and improving the filtration and purification effect of the purification block 12 on the water quality.

[0028] A water quality detector 14 is fixedly connected inside the demineralized water tank 4. A third water level probe 17 is fixedly connected to the bottom of the demineralized water tank 4, and a fourth water level probe 18 is fixedly connected to the middle of the demineralized water tank 4. The water quality detector 14 is used to detect the treated water resources inside the demineralized water tank 4. When the value exceeds the standard, the staff will be notified in time to replace and maintain the purification block 12. The water level inside the demineralized water tank 4 is detected by the third water level probe 17 and the fourth water level probe 18.

[0029] The bottom of the demineralized water tank 4 is fixedly connected to a circulating water pipe 8, and the surface of the circulating water pipe 8 is fixedly connected to a solenoid valve 9. When the water level is lower than the third water level probe 17, the solenoid valve 9 is closed, so that the water resources are stored inside the demineralized water tank 4. When the water level inside the demineralized water tank 4 exceeds the fourth water level probe 18, the solenoid valve 9 is opened, so that the water resources inside the demineralized water tank 4 enter the water circulation system through the circulating water pipe 8 for secondary utilization of the water resources.

[0030] The overpressure drainage pipe 1 and the connecting pipe 6 are made of high-pressure resistant and corrosion-resistant materials, which extends the service life of the pipes and reduces the risk of pipe damage.

[0031] The power water pump 3, water quality detector 14, first water level probe 15, second water level probe 16, third water level probe 17 and fourth water level probe 18 are all electrically connected to an external processor. Through the processor, the operation of the device can be controlled and monitored, and alarm information can be issued in a timely manner when the equipment is abnormal, so as to notify the staff to handle it in time, realize automated operation and precise control, and ensure system stability through fault diagnosis and alarm functions, thereby reducing labor costs and operational risks.

[0032] In use, this invention works as follows: when the equipment pressure is too high, it drains water through the overpressure drain pipe 1 to reduce pressure, and stores the discharged water in the storage tank 2. When the water level is higher than the second water level probe 16, the power water pump 3 is started, and the water is transported to the demineralized water tank 4 through the connecting pipe 6. The water is then filtered and purified by the purification block 12. The water quality detector 14 detects the treated water in the demineralized water tank 4. When the water level in the demineralized water tank 4 exceeds the fourth water level probe 18, the solenoid valve 9 is opened, allowing the water in the demineralized water tank 4 to enter the water circulation system through the circulating water pipe 8 for secondary utilization. By installing a liquid level sensor, the water pump is immediately started when the liquid level reaches the upper limit to prevent water overflow; when the liquid level is too low, the water pump stops to avoid dry pumping and damage to the equipment. This achieves automated operation and precise control. The fault diagnosis and alarm function ensures system stability, reduces labor costs and operational risks, reduces the damage to the equipment caused by water pressure fluctuations, extends the service life of the equipment, enhances the stability and reliability of system operation, reduces drainage treatment costs, and achieves dual control of economic costs.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
