Description

Technical Field

[0001] This utility model relates to the field of reverse osmosis equipment technology, and in particular to a reverse osmosis device for water purification. Background Technology

[0002] Reverse osmosis (RO) equipment is a water treatment system that utilizes semi-permeable membrane technology. Its core principle is to selectively permeate the water through the membrane, removing impurities, salts, organic matter, bacteria, viruses, and other contaminants, thus purifying the water. RO equipment is widely used in drinking water production and industrial water treatment. During operation, the raw water contains suspended solids and dissolved substances such as inorganic salts, colloids, and microorganisms. These substances increase in concentration during RO, easily leading to membrane fouling and reduced performance. To improve performance, chemicals are added to the feed water to prevent membrane fouling and protect the membrane elements.

[0003] In the current technology, conventional dosing methods mainly rely on independent external dosing devices, which typically consist of a dosing pump, a solution tank, and supporting equipment. However, these devices are complex, occupy a large area, and have high procurement and maintenance costs. Furthermore, for small reverse osmosis equipment, installation layout is often difficult. In addition, some simple dosing devices on the market have dosing channels and main channels in a simple parallel mode, lacking effective isolation and control mechanisms. Therefore, we propose a reverse osmosis device for water purification to solve the above problems. Utility Model Content

By setting the handwheel, the threaded rod is driven to rotate upward, so that the drug release assembly moves upward.

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figures 1-3 As shown, a reverse osmosis device for water purification is disclosed, including a frame 1. The reverse osmosis device body 2 and a water pump 3 are fixedly connected inside the frame 1. A dosing tank 4 is fixedly connected inside the frame 1. The dosing tank 4 provides a closed dedicated chamber for mixing chemicals and sewage, so as to avoid the chemicals and sewage being contaminated by the outside during the treatment process. A concave ring 5 is fixedly connected to the inner wall of the dosing tank 4. The concave ring 5 ensures that the metal plate 6 will not shift during the up and down movement, and ensures its sealing fit with the end ring 16 and the rubber gasket 7.

[0021] A metal plate 6 is slidably connected to the inner wall of the concave ring 5, and a rubber pad 7 is fixedly connected to the bottom of the metal plate 6. The rubber pad 7 utilizes the elastic deformation properties of rubber. When the metal plate 6 contacts the end ring 16, the rubber pad 7 can tightly fit the inner wall of the end ring 16, completely blocking the connection between sewage and the dosing chamber, and avoiding waste or pollution caused by sewage mixing with the agent when no dosing is needed.

[0022] The top of the dosing tank 4 is fixedly connected to a dosing pipe, and the top of the dosing pipe is threaded with a sealing cap 13. The outer wall of the dosing tank 4 is fixedly connected to an inlet pipe 14 and an outlet pipe 15. The inside of the dosing tank 4 is fixedly connected to an end ring 16, and the inner wall of the end ring 16 is in contact with the outer wall of the metal plate 6 and the rubber pad 7.

[0023] The top of the metal plate 6 is provided with a drug release assembly, which includes a drive sleeve 8. The top of the metal plate 6 is fixedly connected to the bottom of the drive sleeve 8. The top of the drive sleeve 8 is provided with a T-shaped groove, and a T-shaped column 9 is rotatably connected to the inner wall of the T-shaped groove. The drive sleeve 8 converts the rotational motion of the T-shaped column 9 into the linear lifting motion of the metal plate 6.

[0024] The top of the T-shaped column 9 is fixedly connected to a threaded rod 10. The threaded rod 10 can move up or down when it rotates by engaging with the threaded hole on the top of the dosing tank 4, thereby driving the T-shaped column 9, the drive sleeve 8 and the metal plate 6 to move synchronously. In addition, scale lines are added to the outer wall of the thread to avoid excessive vertical movement.

[0025] A handwheel 12 is fixedly connected to the top of the threaded rod 10. A threaded hole is opened on the top of the dosing tank 4. The inner wall of the threaded hole is threadedly connected to the outer wall of the threaded rod 10. A sealing gasket 11 is fitted on the outer wall of the threaded rod 10. The bottom of the sealing gasket 11 is fixedly connected to the top of the dosing tank 4. The sealing gasket 11 fills the gap between the two through its own elastic deformation, effectively preventing sewage in the dosing tank 4 from leaking from the threaded hole. The output end of the water pump 3 is fixedly connected to one end of the inlet pipe 14, and one end of the outlet pipe 15 is fixedly connected to the outer wall of the reverse osmosis equipment body 2.

[0026] Working principle: During normal operation of the reverse osmosis equipment body 2, wastewater enters through the inlet pipe 14 as it passes through the dosing tank 4. Due to the blockage of the rubber gasket 7 and the metal plate 6 end ring 16, the wastewater passes through the bottom of the inner wall of the dosing tank 4 and is discharged from the outlet pipe 15. When chemical dosing is required, first rotate the sealing cap 13 to expose the dosing pipe, and then allow the chemical (scale inhibitor or reducing agent, etc.) to enter the dosing tank 4 through the dosing pipe. Rotate the sealing cap 13 to press the internal circular rubber gasket against the top of the dosing pipe to seal it. Then, turn the handwheel 1... 2 drives the threaded rod 10 to rotate. After the threaded rod 10 rotates, it rises through the threaded connection with the dosing tank 4, thereby driving the bottom T-shaped column 9 and the drive sleeve 8 to move upward. The drive sleeve 8 drives the metal plate 6 and the rubber pad 7 to move upward, so that they are located in the middle position of the concave ring 5. When the sewage enters the dosing tank 4, the sewage flows slowly into the dosing tank 4 from the gap along the annular guide surface of the concave ring 5 at a stable flow rate, forming a gentle convection mixing with the agent, reducing the problem of uneven concentration of the agent caused by local disturbance. Finally, the sewage mixed with the agent is discharged from the outlet pipe 15.

[0027] It should be noted that when actually put into use, an existing PLC controller can be added. The PLC controller is electrically connected to the reverse osmosis equipment body 2 and the water pump 3 to facilitate the control of the overall operation.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
