Description

Technical Field

[0001] This utility model relates to the field of reverse osmosis technology, specifically to a reverse osmosis device for a seawater desalination pump. Background Technology

[0002] Seawater desalination is the process of producing fresh water by desalinating seawater. It is an incremental technology for realizing the utilization of water resources, which can increase the total amount of fresh water and is not affected by time, space and climate. It can ensure a stable water supply for drinking water for coastal residents and feedwater for industrial boilers. The process of obtaining fresh water from seawater is called seawater desalination. The seawater desalination methods currently used include seawater freezing, electrodialysis, distillation and reverse osmosis.

[0003] According to a public notice of a seawater desalination water pump (publication number: CN212130699U), when seawater enters the pump, it needs to be filtered through a filter box first. The filter box is designed to trap impurities in the seawater that can easily clog the pump inside, thus preventing the pump from clogging due to impurities in the seawater. This allows the pump to maintain a good working condition and avoids the pump from malfunctioning.

[0004] However, in actual use, the amount of liquid entering the permeation chamber of the above-mentioned equipment is difficult to control. Excessive seawater will cause the permeation membrane to be contaminated, and the system also needs to continuously increase the inlet water pressure to overcome higher osmotic pressure and flow resistance, which will affect the reverse osmosis efficiency. In view of this, we propose a reverse osmosis equipment for seawater desalination pumps. Utility Model Content

[0005] The purpose of this invention is to provide a reverse osmosis device for seawater desalination pumps to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a reverse osmosis device for a seawater desalination pump, comprising a filter chamber, an inlet fixedly connected to the side of the filter chamber, a filter plate fixedly installed on the inner wall of the filter chamber, a purification chamber fixedly connected to the side of the filter chamber away from the inlet, a control panel provided on the outer side of the purification chamber, a water pipe fixedly connected to the side of the purification chamber away from the filter chamber, a permeation chamber fixedly connected to the end of the water pipe away from the purification chamber, a permeation membrane fixedly installed in the permeation chamber, a glass window provided on the outer side of the permeation chamber, an outlet fixedly connected to the side of the permeation chamber, an electric valve one fixedly installed on the outlet, a waste liquid outlet fixedly connected to the side of the outlet of the permeation chamber, an electric valve two fixedly installed on the waste liquid outlet, and a control mechanism for pressurizing and controlling the water flow provided in the purification chamber.

[0007] Preferably, the control mechanism includes a connection port, a connection port is provided between the purification chamber and the water pipe, a butterfly valve is rotatably connected in the connection port, a rotating rod is fixedly connected to the side wall of the butterfly valve, a handle is fixedly connected to the end of the rotating rod away from the butterfly valve, a fixed shell is fitted on the outer wall of the water pipe, a centrifugal pump is fixedly installed on the top of the fixed shell, and the centrifugal pump is fixedly connected to the water pipe.

[0008] Preferably, the top of the filter chamber is hinged, and the water inlet is located on the upper part of the side wall of the filter chamber, allowing the filter plate to be cleaned and replaced by opening from the top.

[0009] Preferably, the glass window is provided in two sets, and the two sets of glass windows are located on both sides of the permeation membrane to observe the situation on both sides of the permeation membrane.

[0010] Preferably, the butterfly valve is sized to match the connection port size, and the rotating rod passes through the purification chamber and is fixedly connected to the butterfly valve. Turning the handle causes the butterfly valve to rotate, controlling the liquid flow rate.

[0011] Preferably, the purification chamber is provided with a stirring mechanism for stirring the liquid. The stirring mechanism includes a rotary motor, which is fixedly connected to the top of the purification chamber. A rotating shaft is fixedly connected to the output end of the rotary motor, and stirring blades are fixedly installed on the rotating shaft.

[0012] Preferably, the stirring blades are arranged in several groups on the rotating shaft, and the length of the several groups of stirring blades is adapted to the purification chamber, so that the liquid and the purification liquid are fully mixed.

[0013] Preferably, the stirring mechanism is located at the top of the purification chamber, and the top cover of the purification chamber is hinged. The top cover is opened to add purification liquid to remove impurities from the seawater.

[0014] Compared with the prior art, this utility model provides a reverse osmosis device for seawater desalination pumps, which has the following beneficial effects: 1. This seawater desalination pump uses a reverse osmosis system. By setting up a control mechanism, the system can control the operation rhythm of the entire equipment. The control mechanism, through the combination of a manual butterfly valve and a centrifugal pump, enables flexible and reliable adjustment of the influent flow rate and pressure. This allows the equipment to quickly adapt to different water qualities and changing influent conditions, protecting the cleanliness of the permeate membrane. The same equipment can adapt to different influent conditions. The operation is simple and intuitive, and the application is highly flexible, improving the practicality and adjustability of the equipment.

[0015] 2. This seawater desalination pump uses a reverse osmosis system. By setting up a stirring mechanism, the rotating shaft and multiple layers of stirring blades driven by a rotating motor rotate in the purification chamber, agitating the incoming seawater and the added chemicals. This ensures that the chemicals diffuse and mix in the purification chamber, avoiding uneven mixing and preventing local chemical concentrations from being too high or too low. This improves the treatment effect, provides more stable and safer feed water conditions for the downstream reverse osmosis membrane, and extends the membrane life. Attached Figure Description

[0020] In one embodiment of this utility model, an inlet 2 is fixedly connected to the side of the filter chamber 1 for introducing seawater into the equipment. A filter plate 3 is fixedly installed on the inner wall of the filter chamber 1. The filter plate 3 adopts a multi-layer stainless steel screen structure to effectively intercept larger suspended particles and impurities in the seawater. A purification chamber 4 is fixedly connected to the side of the filter chamber 1 away from the inlet 2. A control panel 5 is installed on the outer wall of the purification chamber 4 for centrally displaying the equipment operating parameters and operating system functions. A water pipe 6 is connected to the side of the purification chamber 4 away from the filter chamber 1 through a pipe. The water pipe 6 is made of high-pressure resistant stainless steel. The end of the water pipe 6 away from the purification chamber 4 is connected to a permeation chamber 7. A reverse osmosis membrane 8 is fixedly installed inside the permeation chamber 7 by a special clamp. A multi-layer tempered glass window 9 is opened on the outer wall of the permeation chamber 7 to facilitate observation of the operation of the reverse osmosis membrane 8. In the purification chamber 7, an outlet 10 and a waste liquid outlet 12 are respectively provided on the side. An electric valve 11 is installed on the outlet 10 to control the discharge of fresh water, and an electric valve 13 is installed on the waste liquid outlet 12 to regulate the discharge of concentrated brine.

[0021] In addition, the top of the filter chamber 1 is hinged, which facilitates opening and cleaning of the internal filter plate 3.

[0022] In this invention, when seawater enters the filter chamber 1 through the inlet 2, it is first initially filtered by the filter plate 3 to intercept larger particles of impurities. The initially filtered seawater flows into the purification chamber 4, which contains a cleaning solution. The rotating shaft 152 and stirring blade 153 of the stirring mechanism 15 are driven by the rotating motor 151 to perform mixing treatment, thus cleaning the seawater again. Subsequently, the water flows into the water pipe 6 through the connection port 141. The seawater volume is adjusted by adjusting the opening degree of the butterfly valve 142, and the centrifugal pump 146 is started to pressurize the water flow. The pressurized seawater enters the permeation chamber 7 and, under pressure, permeates through the reverse osmosis membrane 8 to complete desalination. The resulting fresh water is discharged through the outlet 10 and the first electric valve 11, while the concentrate is discharged through the waste liquid outlet 12 and the second electric valve 13. The operator observes the working status of the permeation membrane 8 and the amount of liquid on both sides of the permeation membrane 8 through the glass window 9 to proceed with the next operation. Finally, the entire system is controlled through the control panel 5.
