The purpose of pretreatment is primarily to ensure the raw water meets the feed water requirements of the reverse osmosis membrane separation components, guaranteeing the stable operation of the reverse osmosis purification system. The reverse osmosis purification system is the most economical and efficient purification method, removing over 98% of ions, organic matter, and theoretically 100% of microorganisms from raw water in a single pass. The ultrapure post-treatment system further removes trace ions, organic matter, and other impurities remaining in the reverse osmosis purified water through various integrated technologies, meeting the final water quality requirements for different applications.
[0003] Currently, reverse osmosis water treatment equipment is widely used in the food processing industry. It can effectively remove dissolved salts, organic matter, heavy metal ions and other impurities from water.
[0004] However, in actual use, traditional water supply devices suffer from unstable pressure, which can affect the normal operation of reverse osmosis equipment, reduce water treatment efficiency, and consequently affect the quality and output of food processing. Utility Model Content

[0011] Beneficial effects
[0012] This utility model provides a constant pressure water supply device for a reverse osmosis water treatment equipment.

[0019] 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.
[0020] In practical use, traditional water supply devices suffer from unstable pressure, which can affect the normal operation of reverse osmosis equipment, reduce water treatment efficiency, and consequently affect the quality and output of food processing.
[0021] In view of this, the present invention provides a constant pressure water supply device for reverse osmosis water treatment equipment, which solves the problem of unstable pressure in traditional water supply devices during actual use. This problem affects the normal operation of reverse osmosis equipment, reduces water treatment efficiency, and consequently affects the quality and output of food processing.
[0022] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0023] Example 1: By Figure 1-4As can be seen, a constant pressure water supply device for reverse osmosis water treatment equipment includes a base 1, a constant pressure box 11 fixedly connected to one side of the top of the base 1, and a filter box 12 fixedly connected to the other side of the top of the base 1. A filter screen 13 is installed inside the filter box 12. The constant pressure water supply device for reverse osmosis water treatment equipment also includes a pressure control device 2, a sealing device 3, and a connecting device 4. The pressure control device 2 is installed inside the constant pressure box 11; the sealing device 3 is installed on the top of the constant pressure box 11; and the connecting device 4 is installed between the constant pressure box 11 and the filter box 12. The pressure control device 2 controls the pressure inside the constant pressure box 11, the sealing device 3 seals the constant pressure box 11, and the connecting device 4 connects the reverse osmosis water treatment equipment and the filter box 12 together.
[0024] In the specific implementation process, it is worth noting that the device is mainly supported by the base 1. Inside the filter box 12, a fine filter screen 13 is carefully installed. Its function is to perform preliminary filtration on the incoming water source, remove larger particles of impurities in the water, and provide higher quality raw water for subsequent reverse osmosis treatment. The sealing device 3 adopts special sealing materials and structural design, which can effectively prevent air from entering the constant pressure box 11 and avoid affecting the stability of water pressure due to gas mixing. The connecting device 4 can smoothly introduce the water that has been pre-filtered by the filter box 12 into the constant pressure box 11. At the same time, it can also transport the water in the constant pressure box 11 that has been treated to meet the constant pressure requirements to the subsequent water use stage, ensuring the continuity and efficiency of the entire water treatment process. The connecting device 4 tightly connects the reverse osmosis water treatment equipment and the filter box 12 together. This constant pressure water supply device of the reverse osmosis water treatment equipment realizes efficient and stable water supply function, providing reliable guarantee for various scenarios with strict requirements on water quality and water pressure.
[0025] Furthermore, the pressure control device 2 includes a sealing block 21, a slot 22, a fixing post 23, a threaded rod 24, and a drive device 25. The sealing block 21 is inserted into the interior of the constant pressure chamber 11; the slot 22 is located below the sealing block 21 and is formed at the bottom of the inner wall of the constant pressure chamber 11; the fixing post 23 is fixedly connected to the top of the sealing block 21 and inserted into the inner wall of the constant pressure chamber 11; the threaded rod 24 is threadedly connected to the inner wall of the fixing post 23 and is rotatably connected to the inner wall of the fixing post 23 through a sealed bearing; the drive device 25 is installed at one end of the threaded rod 24 that extends to the outside of the constant pressure chamber 11; wherein, through the cooperation of the slot 22 and the fixing post 23, the sealing block 21 changes the pressure inside the constant pressure chamber 11, and the drive device 25 drives the threaded rod 24 to rotate;
[0026] In the specific implementation process, it is worth noting that the sealing block 21 is made of a special sealing material and its shape is adapted to the internal shape of the constant pressure box 11. It can be tightly inserted into the inside of the constant pressure box 11, thereby effectively preventing pressure leakage. Moreover, the shape of the slot 22 will match the shape of the sealing block 21. By using the drive device 25 to rotate the threaded rod 24 and the threaded connection between the threaded rod 24 and the fixed column 23, the sealing block 21 is driven to move inside the constant pressure box 11 and the slot 22, thereby changing the internal space of the constant pressure box 11 and thus changing the pressure inside the constant pressure box 11.
[0027] Furthermore, the drive device 25 includes a servo motor 251, a controller 252, and a limiting post 253. The output end of the servo motor 251 is fixedly connected to the top of the threaded rod 24; the controller 252 is electrically connected to the servo motor 251; the limiting post 253 is fixedly connected to the top of the sealing block 21 and inserted into the inner wall of the constant pressure tank 11. The sealing block 21 moves through the cooperation of the servo motor 251 and the controller 252, and the limiting post 253 ensures the stability of the sealing block 21 during movement. The models of the servo motor 251 and the controller 252 are not limited, as long as they meet the actual usage requirements. A pressure sensor is installed inside the reverse osmosis device and is connected to the controller 252, which ensures that the pressure inside the constant pressure tank can be changed according to the pressure inside the reverse osmosis device.
[0028] In the specific implementation process, it is worth noting that when the pressure inside the permeation device decreases, the internal pressure sensor will transmit a signal to the controller 252, and the controller 252 will control the servo motor 251 to rotate, which will drive the threaded rod 24 to rotate, thereby changing the pressure space inside the constant pressure box 11.
[0029] Specifically, when using the constant pressure water supply device of this reverse osmosis water treatment equipment, the pressure inside the osmosis device is determined by the pressure sensor inside the osmosis tank. When the pressure changes, a signal is transmitted to the controller 252, which then controls the controller 252 to rotate the threaded rod 24. When the threaded rod 24 rotates, it connects with the inner wall of the fixed column 23, thereby causing the sealing block 21 to move inside the constant pressure tank 11, changing the internal space of the constant pressure tank 11, and thus changing the liquid pressure inside the constant pressure tank 11, thereby ensuring the water pressure inside the reverse osmosis water treatment equipment.
[0030] Example 2: From Figure 1-4It is known that the sealing device 3 includes a sealing plate 31 and a rubber gasket 32. The sealing plate 31 is installed on the top of the constant pressure box 11 and is fixedly connected to the bottom of the servo motor 251 and the controller 252. The rubber gasket 32 is pressed against the sealing plate 31 and the constant pressure box 11. The interior of the constant pressure box 11 is sealed by the cooperation of the sealing plate 31 and the rubber gasket 32.
[0031] In the specific implementation process, it is worth noting that the rubber pad 32 is placed between the sealing plate 31 and the constant pressure box 11, and the sealing plate 31 is fixed to the top of the constant pressure box 11 with bolts. In this way, when the sealing plate 31 is installed, the rubber pad 32 can be squeezed, so that the connection between the sealing plate 31 and the constant pressure box 11 is tighter, thereby avoiding leakage when adjusting the pressure inside the constant pressure box 11.
[0032] Furthermore, the connecting device 4 includes an inlet pipe 41, a water pump 42, a one-way valve 43, and an outlet pipe 44. The inlet pipe 41 is connected to the outer wall of the filter box 12; the water pump 42 is connected between the filter box 12 and the constant pressure box 11; the one-way valve 43 is installed on one side of the outer wall of the constant pressure box 11; and the outlet pipe 44 is connected to the end of the one-way valve 43 away from the constant pressure box 11. Through the cooperation of the inlet pipe 41 and the water pump 42, the water in the constant pressure box 11 is discharged through the outlet pipe 44. The one-way valve 43 can ensure that the water does not flow back. The model of the one-way valve 43 is not limited, as long as it meets the actual use. The model of the water pump 42 is not limited.
[0033] In the specific implementation process, it is worth noting that when the raw water enters the filter box 12 through the inlet pipe 41, larger impurities will be removed, and the water will enter the constant pressure box 11 through the water pump 42, and then enter the reverse osmosis water treatment device through the one-way valve 43 and the outlet pipe 44.
[0034] Specifically, based on the above embodiments, when the raw water enters the filter box 12 through the inlet pipe 41, impurities will be removed. Then, the water enters the constant pressure box 11 through the water pump 42, and the pressure is adjusted in the constant pressure box 11 so that the adjusted water is discharged through the one-way valve 43 and enters the reverse osmosis water treatment device through the outlet pipe 44.
