Description

Technical Field

[0001] The invention relates to the technical field of water treatment equipment, in particular to a water-saving device suitable for a circulating cooling water system. Background Art

[0002] As the global water shortage problem becomes increasingly serious, water-saving technology has become a focus of attention in various industries. As an important part of industrial water, the operating efficiency of the circulating cooling water system not only affects the operating costs of the factory, but is also directly related to its environmental performance. Although the circulating cooling water systems on the current market have a certain recycling capacity, there are still many challenges in actual operation. Problems such as scaling and corrosion have caused the water quality to deteriorate continuously, which not only increases the system maintenance cost, but also significantly increases energy consumption, thereby affecting production efficiency.

[0003] In order to deal with the scaling and corrosion problems of circulating cooling water systems, the market generally adopts two solutions: physical and chemical methods. The physical method removes scale in the pipes through high-frequency vibrators, ultrasound and other means, which can effectively remove existing deposits, but has limited effect in preventing the formation of new scale. The chemical method prevents scale formation and protects the metal surface by adding chemicals such as scale inhibitors and corrosion inhibitors, but this method is prone to environmental pollution problems, and long-term use may lead to water quality deterioration. Both methods have their own advantages and disadvantages, but it is difficult to fundamentally solve the core problems in the circulating cooling water system.

[0004] Although physical and chemical methods can alleviate the scaling problem to a certain extent, their application in large cooling water systems still has many shortcomings. These methods are complex to operate, have high operating costs, and are difficult to maintain efficient and stable operation of the system for a long time, thus restricting the improvement of overall economic benefits. Therefore, there is an urgent need for an innovative solution that can combine the advantages of existing methods while overcoming their limitations, achieve comprehensive breakthroughs in water saving, cost reduction and environmental protection, and provide technical support for the sustainable development of industrial circulating cooling water systems.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Please see attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 7 , Attachment Figure 8 and attached Fig. 9 The embodiment of the present invention provides a water-saving device suitable for a circulating cooling water system, including a treatment box 1. The device improves water resource utilization, operation stability and maintenance convenience by optimizing structural design and multiple innovative functions. The left and right side walls of the treatment box 1 are respectively provided with a water inlet pipe 2 and a water outlet pipe 3. A reverse osmosis processor 4 is installed inside the water inlet pipe 2, which is used to preliminarily purify the circulating cooling water entering the system, remove dissolved salts, calcium and magnesium ions and other tiny impurities in the water, reduce the possibility of scale formation, and ensure the stable operation of subsequent equipment. A control box 7 and a sensor module 13 are also provided inside the treatment box 1. The control system inside the control box 7 dynamically adjusts the electromagnetic field intensity according to the data fed back by the sensor module 13, which not only ensures the descaling efficiency but also saves electric energy. An electromagnetic descaling device 8 is installed inside the treatment box 1, and a descaling controller 9 is arranged above it. Its function is to generate an electromagnetic field of a specific frequency to inactivate the calcium and magnesium ions in the water and generate floccules, thereby reducing the adhesion of scale in the pipeline. The two ends of the electromagnetic descaling device 8 are connected to the water inlet pipe 2 and the water outlet pipe 3 respectively through flanges 20. In order to increase the sealing performance of the flanges 20 and prevent water leakage, a hoop 10 is sleeved on the outer side of the two flanges 20. The hoop 10 adopts an elastic design and can adapt to different connection pressures during installation. At the same time, a buckle assembly 11 is provided on the outer side thereof; The buckle assembly 11 is composed of a fixing block 111 and a card box 113. The fixing block 111 is provided with inner fixing grooves 112 on both sides thereof. A control rod 114 is slidably connected to the inside of the card box 113. A force spring 115 is sleeved on the outside of the control rod 114. One end of the spring is fixedly connected to a force plate 116 of the control rod 114, and the other end is fixed to the inner wall of the card box 113. Both sides of the force plate 116 are connected to the clamping block 118 through a rotating rod 117. The clamping block 118 can be inserted into the inner fixing groove 112 of the fixing block 111, thereby realizing the rapid installation and fixation of the hoop 10. This design not only enhances the sealing of the pipe connection, but also facilitates the disassembly and replacement of the hoop 10, greatly improving the maintenance efficiency.

[0025] See attached Figure 7 and attached Fig.10 In order to solve the vibration problem generated during the operation of the electromagnetic descaling device 8, two shock absorbing rings 12 are sleeved on the outside thereof, and a shock absorbing block 18 is fixedly connected to the bottom of the shock absorbing ring 12. A shock absorbing assembly 19 is arranged inside the shock absorbing block 18, and the shock absorbing assembly 19 includes a top plate 191 and two bottom blocks 192. Two dampers 194 are arranged between the top plate 191 and the two bottom blocks 192. The damper 194 is used to absorb vibration energy and reduce the impact during the operation of the equipment. A sliding rod 195 is arranged between the two bottom blocks 192, and a pressure spring 197 is sleeved on the outside of the sliding rod 195. The two sides of the pressure spring 197 are respectively slidably connected in the sleeve 196, and the sleeve 196 is connected to the top plate 191 through a force rod 193, thereby forming a complete shock absorbing structure. The shock absorbing assembly 19 can effectively absorb the vibration generated during the operation of the equipment, avoid problems such as loose connection of the equipment and leakage of circulating water caused by vibration, and further improve the reliability and safety of the equipment operation.

[0026] See attached Figure 1 , Attachment Figure 3 and attached Figure 4 In order to ensure the working environment inside the processing box 1 and prevent the influence of water vapor on the electronic components and the sensor module 13, the front and rear side walls of the processing box 1 are respectively installed with a filter 6 and an exhaust fan 14. The filter 6 is equipped with a desiccant inside, which can absorb the moisture in the box and prevent the external water vapor from entering, so as to maintain the dry environment inside the box. The filter 6 is sealed with the processing box 1 through a rubber sealing ring and can be quickly disassembled to replace the desiccant. The exhaust fan 14 is used to discharge excess moisture and maintain internal air circulation, thereby protecting the electronic components and the sensor module 13 in the processing box 1 and ensuring the long-term stable operation of the equipment.

[0027] See attached Figure 1 , Attachment Figure 5 , Attachment Figure 6 and attached Fig.10In order to deal with the floccules generated after the operation of the electromagnetic descaling device 8, a filter plate 21 is installed inside the water outlet pipe 3. The filter plate 21 is used to intercept the floccules and impurities generated after the operation of the electromagnetic descaling device 8 to prevent them from entering the outlet of the circulating cooling water. At the same time, a backwash pump 15 is arranged at the top of the water outlet pipe 3. The filter plate 21 is regularly cleaned by the backwash pump 15 to ensure the permeability of the filter plate 21 and avoid the system flow rate from decreasing or blocking due to the accumulation of impurities. A sewage outlet 16 is arranged at the bottom of the water outlet pipe 3, and an anti-blocking component 17 is installed inside the sewage outlet 16. The anti-blocking component 17 includes an impeller 171 and a filter cartridge 174. A connecting rod 175 is fixedly connected to the middle of the impeller 171, and a fixed plate 172 is rotatably connected to the outer side of the connecting rod 175. A brush 173 is fixedly connected to the bottom of the connecting rod 175. The brush 173 abuts against the inner wall of the filter cartridge 174 to clean the impurities inside the filter cartridge 174. The outside of the sewage outlet 16 is connected to the filter pipe 5, and the filter cartridge 174 is fixed to the bottom of the sewage outlet 16 by threaded connection and is located inside the filter pipe 5. The impeller 171 drives the connecting rod 175 to rotate under the action of the water flow, thereby driving the brush 173 to automatically clean the filter cartridge 174 to prevent impurities from clogging the filter cartridge 174 and affecting the sewage discharge effect. At the same time, the filter cartridge 174 can be quickly disassembled, which is convenient for cleaning the accumulated floccules and impurities, ensuring that the sewage outlet 16 is unobstructed and improving the reuse efficiency of circulating water.

[0028] Working principle: First, the circulating water enters the device from the water inlet pipe 2, and after the reverse osmosis processor 4 preliminarily purifies the dissolved salts and impurities in the water, it enters the treatment box 1. The electromagnetic descaling device 8 in the treatment box 1 generates an electromagnetic field of a specific frequency to inactivate the calcium and magnesium ions in the water and form flocs to prevent scaling. The flanges 20 at both ends of the electromagnetic descaling device 8 are sealed and connected to the pipeline through the hoop 10 to prevent water leakage, and the hoop 10 can be quickly disassembled and assembled through the snap assembly 11. The shock absorbing ring 12 and the shock absorbing assembly 19 on the outside of the electromagnetic descaling device 8 absorb the vibration during operation to avoid loose connection or leakage of the equipment. The water after electromagnetic treatment flows into the outlet pipe 3, where the filter plate 21 intercepts part of the flocs and impurities, and the backwash pump 15 at the top regularly cleans the filter plate 21 to ensure patency. The filtered water enters the circulating cooling water system for continued use, and the separated flocs are discharged through the sewage outlet 16 at the bottom of the outlet pipe 3. The anti-blocking component 17 inside the sewage outlet 16 drives the connecting rod 175 to drive the brush 173 through the impeller 171 to clean the impurities on the inner wall of the filter cartridge 174 to ensure smooth sewage discharge. The filter cartridge 174 is fixed by a threaded connection and can be quickly disassembled for deep cleaning. The circulating water that has been further filtered by the filter cartridge 174 can be returned to the circulating cooling water system through the filter pipe 5. In order to ensure the stability of the humidity inside the treatment box 1, the filter 6 and the exhaust fan 14 work together. The desiccant inside the filter 6 absorbs water vapor and prevents external moisture from entering. The exhaust fan 14 discharges excess moisture to protect the normal operation of the control box 7 and the sensor module 13. The above multi-stage treatment design ensures the purification and water-saving effects of the circulating water. At the same time, the optimized equipment structure improves the operational stability and maintenance convenience.

[0029] Working principle: First, the circulating water enters the device from the water inlet pipe 2, and after the reverse osmosis processor 4 preliminarily purifies the dissolved salts and tiny impurities in the water, it flows into the treatment box 1. In the treatment box 1, the electromagnetic descaling device 8 acts on the water flow by generating an electromagnetic field of a specific frequency, so that the calcium and magnesium ions in the water are inactivated and floccules are generated, which prevents the deposition of scale on the surface of the pipe or equipment, thereby reducing the scaling problem. The circulating water treated by the electromagnetic descaling device 8 flows into the outlet pipe 3 with the generated floccules. The filter plate 21 inside the outlet pipe 3 preliminarily intercepts part of the floccules and impurities to ensure the cleanliness of the outlet water; the backwash pump 15 installed on the top of the filter plate 21 regularly cleans the filter plate 21 to prevent blockage caused by impurity accumulation, thereby ensuring the smoothness of the water flow. The clean water flows back to the circulating cooling water system through the outlet pipe 3 for continued use, and the separated floccules and impurities are discharged through the sewage outlet 16 at the bottom of the outlet pipe 3.

[0030] An anti-blocking component 17 is designed inside the sewage outlet 16, which includes an impeller 171, a connecting rod 175, a brush 173 and a filter cartridge 174. During the sewage discharge process, the water flow drives the impeller 171 to rotate, and the brush 173 is driven by the connecting rod 175 to automatically clean the inner wall of the filter cartridge 174 to prevent impurities from clogging the filter cartridge 174, thereby ensuring smooth drainage of the sewage outlet 16. The filter cartridge 174 is fixed to the sewage outlet 16 by a threaded connection, which is convenient for quick disassembly and deep cleaning. The circulating water further filtered by the filter cartridge 174 can flow back to the circulating cooling water system through the filter pipe 5, further improving the utilization efficiency of water resources.

[0031] The flanges 20 at both ends of the electromagnetic descaling device 8 are sealed and connected to the water inlet pipe 2 and the water outlet pipe 3 through the hoop 10. The hoop 10 is fixed by a buckle assembly 11, which is composed of a fixing block 111, a card box 113 and a control rod 114. The hoop 10 can be quickly disassembled and assembled through simple operations, which is convenient for equipment maintenance. At the same time, the sealing of the pipeline connection is ensured to effectively prevent leakage of circulating water. In order to cope with the vibration generated during the operation of the electromagnetic descaling device 8, a shock absorbing ring 12 is designed on the outside, and a shock absorbing block 18 and a shock absorbing assembly 19 are set at the bottom. The shock absorbing assembly 19 is composed of a top plate 191, a bottom block 192, a damper 194, a slide rod 195 and a pressure spring 197, which can absorb vibration energy, avoid loosening of equipment connection or water leakage caused by vibration, and improve operation stability and equipment service life.

[0032] In order to ensure the stability of the humidity environment inside the processing box 1, the device is designed with a moisture control system. The front and rear side walls of the processing box 1 are respectively installed with a filter 6 and an exhaust fan 14. The filter 6 is filled with a desiccant to absorb the moisture inside the processing box 1 and prevent the entry of external moisture. The filter 6 is sealed with the side wall of the box through a rubber sealing ring and can be quickly disassembled to replace the desiccant. The exhaust fan 14 works in coordination to timely discharge the excess moisture inside the box and maintain the internal dry environment, thereby protecting the normal operation of the control box 7 and the sensor module 13 and ensuring the long-term stability of the equipment operation.
