Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical and chemical technology, and in particular to a concentrated water recovery and reuse device. Background Technology

[0002] Recycling and reuse devices are equipment used to treat and process waste (such as solid waste, liquid waste, and gaseous waste) and extract usable resources. They achieve resource recycling through physical, chemical, or biological methods and are applied in environmental protection, industry, and other fields to reduce waste. Concentrated water recycling devices are used to treat high-concentration wastewater generated in industrial and sewage treatment. They remove impurities through membrane separation, ion exchange, and other technologies, purify the concentrated water, and reuse it. This can save water resources and reduce emissions, and is widely used in chemical, power, and other fields.

[0003] In existing technologies, some water purification equipment removes suspended solids, colloids and other impurities from raw water through pretreatment, then uses a reverse osmosis membrane to retain most of the ions and organic matter, supplemented by ion exchange resin for deep adsorption of the remaining ions, and ultraviolet sterilization to inactivate microorganisms, ultimately producing purified water that meets purity standards for use in the pharmaceutical, electronics and other fields.

[0004] However, in existing technologies, some purified water preparation equipment uses a two-stage reverse osmosis device. The concentrated water produced by the first-stage reverse osmosis has high hardness and high conductivity, making it difficult to reuse and is directly discharged as wastewater. Therefore, a concentrated water recycling and reuse device is proposed to solve the above problems. Utility Model Content

[0024] 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.

[0025] Reference Figures 1 to 3 This utility model provides an embodiment of a concentrate recovery and reuse device, including a support frame 1. The support frame 1 serves as the mounting foundation for the entire device, providing a stable support platform for each component and ensuring that the device does not shake or shift during operation. A direct discharge pipe 2 for primary concentrate from a reverse osmosis system is fixedly connected to the top left side of the support frame 1. The direct discharge pipe 2 for primary concentrate from the reverse osmosis system is used to transport the primary concentrate produced by the reverse osmosis system to the subsequent treatment mechanism. A quick-release mechanism 3 for inlet pipe a is fixedly connected to the outer right side of the direct discharge pipe 2 for easy access. To enable quick connection and disassembly between pipes, it facilitates subsequent cleaning and maintenance of the pipe interior, and also improves the installation efficiency of the device. The high-pressure pump inlet pipe b4 is slidably connected to the outer right side of the quick-disassembly mechanism 3 of the inlet pipe a. The high-pressure pump inlet pipe b4 plays the role of conveying concentrated water, and delivers the concentrated water that has passed through the quick-disassembly mechanism 3 of the inlet pipe a to the primary concentrated water recovery mechanism 5. The primary concentrated water recovery mechanism 5 is fixedly connected to the outer right side of the high-pressure pump inlet pipe b4. The primary concentrated water recovery mechanism 5 is the core mechanism for the recovery and treatment of concentrated water, and can perform concentrated water filtration operation to realize the reuse of concentrated water.

[0026] The primary concentrate recovery mechanism 5 includes a high-pressure water pump 51, which is a key power source. The high-pressure water pump 51 draws in concentrate and pressurizes it to provide sufficient pressure for subsequent filtration. The input end of the high-pressure water pump 51 is fixedly connected to the outside right side of the high-pressure pump inlet pipe b4. Through this connection, it can smoothly receive the delivered concentrate. The control end of the high-pressure water pump 51 is fixedly connected to a frequency converter support assembly 52, which provides a stable mounting support for the frequency converter 522. On the other hand, the speed of the high-pressure water pump 51 can be adjusted by the frequency converter 522, thereby changing the delivery pressure and flow rate of the concentrate to adapt to different treatment needs. A high-pressure pump outlet pipe 53 is fixedly connected to the output end of the high-pressure water pump 51. The high-pressure pump outlet pipe 53 is used to transport the concentrate pressurized by the high-pressure water pump 51 to the concentrate treatment pipe 55. A pressure gauge assembly 54 is fixedly connected inside the high-pressure pump outlet pipe 53. The pressure gauge assembly 54 can monitor the water pressure changes in the high-pressure pump outlet pipe 53 and the high-pressure pump inlet pipe b4 in real time. The operator can adjust the pressure according to the pressure changes. The pressure gauge reading is used to adjust the operating parameters of the high-pressure water pump 51 in a timely manner to ensure the safe and stable operation of the device. A concentrated water treatment pipe 55 is fixedly connected to the right side of the high-pressure pump outlet pipe 53. The concentrated water treatment pipe 55 is the main site for filtering the concentrated water, and it is equipped with a filter assembly 57 to effectively remove impurities from the concentrated water. Two support rings 56 are fixedly connected to the outside of the concentrated water treatment pipe 55. The two support rings 56 can firmly fix the concentrated water treatment pipe 55 to the support frame 1 to prevent the concentrated water treatment pipe 55 from being damaged by water flow during operation. Displacement and vibration occur, and the bottom of the two support rings 56 are fixedly connected to the top of the support frame 1, which further enhances the stability of the concentrated water treatment pipe 55. The concentrated water treatment pipe 55 is fixedly connected to the inside of the filter assembly 57, which is composed of multi-stage filter membranes, which can perform deep filtration of concentrated water, improve the purification effect of concentrated water, and enable the treated water to meet the standards for reuse. The middle of the inside of the concentrated water treatment pipe 55 is fixedly connected to the extra-concentrated water discharge pipe 58, which is used to discharge the extra-concentrated water generated after filtration to the sewage treatment plant.

[0027] The frequency converter support assembly 52 includes a frequency converter 522. The frequency converter 522 adjusts the speed of the high-pressure water pump 51 by changing the output frequency, thereby achieving precise control of water pressure and flow rate. The output end of the frequency converter 522 is fixedly connected to the control end of the high-pressure water pump 51, enabling accurate transmission of control signals to the high-pressure water pump 51. L-shaped support plates 521 are fixedly connected to both external sides of the frequency converter 522. The L-shaped support plates 521 can stably support the frequency converter 522 on the support frame 1. The bottom of the two L-shaped support plates 521 are fixed. The pressure gauge assembly 54 includes a post-pump pressure gauge 541, which is installed inside the high-pressure pump outlet pipe 53. This gauge displays the real-time water pressure at the output of the high-pressure pump 51, allowing operators to monitor the concentrated water pressure after pressurization. The bottom of the post-pump pressure gauge 541 is fixedly connected inside the high-pressure pump outlet pipe 53 using a threaded connection for easy installation and replacement. The high-pressure pump inlet pipe b4 is also fixedly connected to the pre-pump pressure gauge. Pressure gauge 542, the pressure gauge before the pump, is used to monitor the water pressure at the input end of the high-pressure water pump 51. By comparing the reading with that of the pressure gauge after the pump, it can be determined whether the high-pressure water pump 51 is working properly. The filter assembly 57 includes membrane housing 571, which provides installation space and protection for the primary filter membrane 572, ensuring that the concentrate can pass through the primary filter membrane 572 evenly. The external of membrane housing 571 is fixedly connected to the inside left side of the concentrate treatment pipe 55, and is firmly installed and not easy to loosen. The internal of membrane housing 571 is fixed. A primary filter membrane 572 is connected, which can remove larger particles of impurities and some soluble substances from the concentrate. A second membrane housing 573 is fixedly connected to the inside right side of the concentrate treatment pipe 55. The function of the second membrane housing 573 is similar to that of the first membrane housing 571, providing support and protection for the second-stage filter membrane 574. The second membrane housing 574 is fixedly connected inside the second membrane housing 573. The filtration accuracy of the second-stage filter membrane 574 is higher than that of the primary filter membrane 572, which can further remove fine impurities and organic matter in the concentrate and improve the purification quality of the concentrate.

[0028] Reference Figure 1 , Figure 3 and Figure 4The quick-release mechanism 3 of the inlet pipe a includes a high-pressure pump anti-clogging component 31. This component effectively blocks large particles of impurities in the concentrate from entering the high-pressure pump 51, preventing damage due to blockage and extending the equipment's lifespan. The outer left side of the high-pressure pump anti-clogging component 31 is fixedly connected to the outer right side of the first-stage concentrate direct discharge pipe 2 of the reverse osmosis equipment, ensuring a tight connection and preventing concentrate leakage. A ball-positioning component 32 is fixedly connected to the outer side of the high-pressure pump inlet pipe b4. This component provides installation and movement space for the sliding ball retainer 35, ensuring that the sliding ball retainer 35 can... To ensure normal operation and facilitate rapid pipe connection, the ball-holding assembly 32 has an external sliding connection with a T-ring 33. The T-ring 33 can slide outside the ball-holding assembly 32. By squeezing and releasing the sliding ball 35, pipe connection and disconnection are achieved. A spring 34 is located on the outer left side of the ball-holding assembly 32. The spring 34 has an elastic return function, providing continuous pressure to the T-ring 33 during pipe connection, keeping the sliding ball 35 engaged with the trapezoidal groove 313, ensuring the sealing and stability of the connection. The ball-holding assembly 32 also has multiple internal sliding connections. The movable ball 35, or sliding ball 35, serves as a connection between the ball placement assembly 32 and the high-pressure pump anti-clogging assembly 31. Through its cooperation with the trapezoidal groove 313, it enables quick pipe connection. The high-pressure pump anti-clogging assembly 31 includes a high-pressure pump inlet pipe a311, which is the channel for concentrated water to enter the quick-release mechanism 3 of the inlet pipe a. It connects to the first-stage concentrated water direct discharge pipe 2 of the reverse osmosis equipment and the ball placement assembly 32, ensuring smooth flow of concentrated water. The outer left side of the high-pressure pump inlet pipe a311 is fixedly connected to the outer right side of the first-stage concentrated water direct discharge pipe 2 of the reverse osmosis equipment. The pump anti-clogging component 31 has an anti-clogging filter 312 fixedly connected inside. The anti-clogging filter 312 can effectively intercept large particulate impurities in the concentrated water. The high-pressure pump inlet pipe a311 has multiple trapezoidal grooves 313 inside. The shape of the trapezoidal grooves 313 matches the sliding ball 35. When the sliding ball 35 is inserted into the trapezoidal groove 313, the high-pressure pump inlet pipe a311 and the ball placement component 32 can be firmly connected. The inside of the trapezoidal groove 313 is slidably connected to the outside of the sliding ball 35, ensuring that the sliding ball 35 can slide flexibly in the trapezoidal groove 313, which facilitates the disassembly of the pipe.

[0029] The ball placement assembly 32 includes a ball placement ring 321, which is fitted onto the outside of the high-pressure pump inlet pipe b4, providing an installation base for the ball placement grooves 322 and the fixing ring 323. The ball placement ring 321 is internally and fixedly connected to the outside of the high-pressure pump inlet pipe b4, ensuring a secure connection and preventing it from easily falling off. Multiple ball placement grooves 322 are provided inside the ball placement ring 321, the number and position of which correspond to the sliding ball retainer 35, providing movement space for the sliding ball retainer 35. The inside of the ball placement grooves 322 is slidably connected to the outside of the sliding ball retainer 35, allowing the sliding ball retainer 35 to slide freely within the ball placement grooves 322. A fixing ring 323 is fixedly connected to the outside of the ball placement ring 321, providing support for the spring 34 and also limiting the sliding range of the T-shaped ring 33. The outside of the fixing ring 323 is slidably connected to the inside of the T-shaped ring 33. To ensure that the T-ring 33 can slide smoothly along the outside of the fixed ring 323, the outer right side of the spring 34 is set on the outer left side of the fixed ring 323. One end of the spring 34 is in contact with the fixed ring 323, and the other end is connected to the T-ring 33. The other end of the spring 34 is fixedly connected to the outside of the T-ring 33. When the T-ring 33 is pushed, the spring 34 is compressed, generating elastic potential energy. After the T-ring 33 is released, the spring 34 returns to its original state, driving the T-ring 33 back to its initial position. The inside of the ball-holding ring 321 is slidably connected to the outside of the high-pressure pump inlet pipe a311, so that the ball-holding ring 321 can slide outside the high-pressure pump inlet pipe a311, which facilitates the connection and disassembly of the pipe. The outside of the ball-holding ring 321 is slidably connected to the inside of the T-ring 33, ensuring that the T-ring 33 can effectively squeeze the sliding ball 35 inside the ball-holding ring 321.

[0030] Working principle: The primary concentrate produced by the reverse osmosis equipment first enters the primary concentrate direct discharge pipe 2 of the reverse osmosis equipment, and is then transported to the quick-release mechanism 3 of the inlet pipe a. At the quick-release mechanism 3 of the inlet pipe a, the high-pressure pump inlet pipe a311 is connected to the primary concentrate direct discharge pipe 2 of the reverse osmosis equipment. The concentrate first undergoes preliminary filtration through the anti-clogging filter screen 312 in the high-pressure pump anti-clogging component 31 to intercept larger particles of impurities in the water. At the same time, the ball-placement ring 321 in the ball-placement component 32 is sleeved on the outside of the high-pressure pump inlet pipe a311. The sliding retaining ball 35 in the ball-placement groove 322 cooperates with the trapezoidal groove 313 on the high-pressure pump inlet pipe a311. Under the elastic force of the spring 34, the T-shaped ring 33 presses the fixing ring 323, realizing a quick sealing connection between the high-pressure pump inlet pipe a311 and the high-pressure pump inlet pipe b4.

[0031] The filtered concentrate enters the high-pressure water pump 51 in the primary concentrate recovery mechanism 5 through the high-pressure pump inlet pipe b4. The high-pressure water pump 51 is controlled by the frequency converter support assembly 52. ​​The frequency converter 522 is fixed to the support frame 1 by the L-shaped support plate 521. The operating frequency of the high-pressure water pump 51 is adjusted according to system requirements. After being pressurized by the high-pressure water pump 51, the concentrate enters the high-pressure pump outlet pipe 53. At this time, the pressure gauge 542 before the pump monitors the pressure in the high-pressure pump inlet pipe b4, and the pressure gauge 541 after the pump monitors the pressure in the high-pressure pump outlet pipe 53 to ensure stable system pressure. The concentrated water enters the concentrated water treatment pipe 55 through the high-pressure pump outlet pipe 53. The concentrated water treatment pipe 55 is fixed to the top of the support frame 1 by two support rings 56. The concentrated water first flows through the membrane housing 571 in the filter assembly 57 and is filtered again by the internal primary filter membrane 572 to remove some solutes and impurities in the water. Then it enters the membrane housing 573 and is further filtered by the secondary filter membrane 574. After two stages of filtration, the qualified water can be recycled and reused, while the concentrated extra-concentrated water is discharged through the extra-concentrated water discharge pipe 58 in the middle of the concentrated water treatment pipe 55.
