Description

Technical Field

[0001] This invention relates to the field of reverse osmosis water treatment, and more particularly to a reverse osmosis purified water device. Background Technology

[0002] In fields such as pharmaceuticals, chemicals, and bioengineering where high-purity water is required, reverse osmosis technology is a core water purification method. Reverse osmosis water purification equipment uses a high-pressure pump to apply pressure to the raw water, causing it to overcome osmotic pressure and pass through a reverse osmosis membrane that only allows water molecules to pass through. This effectively removes most impurities in the water, such as dissolved salts, colloids, bacteria, and viruses, to obtain high-purity product water.

[0003] In order to ensure a stable water production flow and system recovery rate, existing reverse osmosis purified water equipment requires high-pressure pumps to run for a long time or even continuously to maintain a constant high-pressure environment within the membrane module. This results in high energy consumption and significantly increases operating costs. For pharmaceutical and chemical production lines that require continuous operation, energy consumption has become a significant operational burden. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a reverse osmosis water purification device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a reverse osmosis purified water device, comprising a treatment tank, a stirring device fixedly connected to the top of the treatment tank, a bottom cover fixedly connected to the bottom of the treatment tank, a support fixedly connected to the outside of the treatment tank, a fixed frame fixedly connected to the upper part of the inside of the treatment tank, a rotating column fixedly connected to the lower part of the fixed frame, a lifting plate movably connected to the upper part of the inside of the treatment tank, a guide cylinder fixedly connected between the lifting plate and the treatment tank, the lifting plate comprising a plate body movably connected to the upper part of the inside of the treatment tank, an inner sealing sleeve fixedly connected to the inside of the plate body, an outer sealing sleeve fixedly connected to the outside of the plate body, columns fixedly connected to both sides of the top of the plate body, a rotating shaft movably connected to the inside of the column, and a ball bearing movably connected to one end of the rotating shaft near the rotating column.

[0006] Further: The processing tank includes a tank body, with a water inlet pipe fixedly connected to the left side of the tank body, a waste pipe fixedly connected to the right side of the tank body, and an upper sealing gasket fixedly connected to the lower part of the tank body.

[0007] Further: The rotating column includes a column body fixedly connected to the lower part of the fixed frame. The outer side of the column body is provided with an inclined groove and a spiral groove, and the beginning and end of the inclined groove and the spiral groove are connected to each other.

[0008] Further: The fixing frame includes a frame body fixedly connected to the upper part of the inside of the processing barrel. The frame body is movably connected to the inside of the processing barrel by a rotating rod. A limit ring is fixedly connected to the lower part of the outer side of the rotating rod, and a driven gear is fixedly connected to the upper part of the outer side of the limit ring.

[0009] Further: The stirring device includes a variable speed motor fixedly connected to the top of the processing tank, a drive shaft fixedly connected to the output end of the variable speed motor, a drive gear fixedly connected to the upper outer side of the drive shaft, a stirring blade fixedly connected to the middle of the outer side of the drive shaft, and a spiral guide plate fixedly connected to the lower outer side of the drive shaft.

[0010] Further: The guide cylinder includes a cylinder body fixedly connected to the upper part of the inside of the processing tank and a lifting rod on the top of the lifting plate. A limit block is fixedly connected to the top of the lifting rod. A spring is fixedly connected between the cylinder body and the limit block. The cylinder body is movably connected to the limit block and the lifting rod.

[0011] Further: The bottom cover includes a cover body fixedly connected to the lower part of the treatment tank. A flow guide is fixedly connected to the lower part of the cover body. A pure water pipe is fixedly connected to the lower part inside the flow guide. A backflushing pipe is fixedly connected to the left side inside the flow guide. A lower sealing gasket is fixedly connected to the top of the tank body. A reverse osmosis membrane is placed on the top of the lower sealing gasket. Bolts are movably connected to the inside of the cover body, the reverse osmosis membrane, and the lower sealing gasket.

[0012] Further: The support includes a fixing sleeve fixedly connected to the outside of the processing tank, a support column fixedly connected to the lower part of the fixing sleeve, a fixing block fixedly connected to the lower part of the support column, and a fixing hole provided inside the fixing block.

[0013] The present invention has the following beneficial effects:

[0014] 1. Compared with the prior art, the present invention, by providing a lifting plate, rotating column and fixed frame, helps to reduce equipment energy consumption. While the stirring device is started to stir the raw water, the driven gear drives the rotating rod to rotate, which in turn drives the column to rotate counterclockwise. When the ball is in the spiral groove, as the column rotates counterclockwise, the column will squeeze the ball, which will cause the rotating shaft to drive the column to rise and fall, and then drive the plate to rise and fall. The rising and falling of the plate can intermittently apply pressure to the raw water, reducing the running time of the high-pressure pump and reducing energy consumption.

[0015] 2. Compared with the prior art, the present invention, by incorporating a stirring device, helps to reduce the accumulation of impurities on the reverse osmosis membrane. Activating the variable speed motor enables the drive shaft to rotate the stirring blades and the spiral guide plate. The rotation of the stirring blades facilitates the stirring of the raw water, ensuring a more uniform concentration throughout the raw water. The rotation of the spiral guide plate continuously pushes the raw water from the bottom upwards, preventing excessive accumulation of impurities on the reverse osmosis membrane and ensuring better separation efficiency of the reverse osmosis membrane.

[0026] Reference Figure 1-8The present invention provides a reverse osmosis purified water device, comprising a treatment tank 1, a stirring device 5 fixedly connected to the top of the treatment tank 1, a bottom cover 7 fixedly connected to the bottom of the treatment tank 1, a support 8 fixedly connected to the outside of the treatment tank 1, a fixing frame 4 fixedly connected to the upper part of the inside of the treatment tank 1, a rotating column 3 fixedly connected to the lower part of the fixing frame 4, a lifting plate 2 movably connected to the upper part of the inside of the treatment tank 1, a guide cylinder 6 fixedly connected between the lifting plate 2 and the treatment tank 1, the lifting plate 2 including a plate body 201 movably connected to the upper part of the inside of the treatment tank 1, an inner sealing sleeve 202 fixedly connected inside the plate body 201, the inner sealing sleeve 202 being made of rubber material to ensure better sealing between the plate body 201 and the tank body 101, and a fixed connection on the outside of the plate body 201. An outer sealing sleeve 203, made of rubber, is provided to ensure a better seal between the disc body 201 and the drive shaft 503. Columns 204 are fixedly connected to both sides of the top of the disc body 201. A rotating shaft 205 is movably connected inside the column 204, allowing rotation within the column 204. A ball bearing 206 is movably connected to one end of the rotating shaft 205 near the rotating column 3, allowing it to roll inside the rotating column 3 and fit against the column body 301. A high-pressure pump is installed on the water inlet pipe 102. During use, raw water is introduced into the tank 101 through the water inlet pipe 102 for separation. Simultaneously, the variable speed motor 501 is activated, causing the drive shaft 503 to rotate clockwise, which in turn drives the stirring blade 504 to rotate, facilitating the separation of the raw water. During stirring, the spiral guide plate 505 rotates synchronously, facilitating the continuous upward movement of the raw water from the bottom. This prevents excessive accumulation of impurities on the reverse osmosis membrane 704, ensuring better separation efficiency. Simultaneously, the rotation of the drive shaft 503 drives the active gear 502, which meshes with the driven gear 402. The rotation of the active gear 502, in turn, causes the driven gear 402 to drive the rotating rod 404, which in turn drives the column 301 to rotate counterclockwise. When the ball bearing 206 is in the spiral groove 303, the counterclockwise rotation of the column 301 compresses the ball bearing 206, causing the rotating shaft 205 to drive the column 204 downward, which in turn drives the disc 201 downward. The descent of the disc 201 allows it to compress the raw water, enabling pure water to pass through the reverse osmosis membrane 704, thus facilitating normal separation. When the ball bearing 206 is in the inclined groove 302, the disc 201 moves upward to prepare for the next descent. The circumferential length of the inclined groove 302 is much smaller than that of the spiral groove 303, allowing the disc 201 to rise quickly and descend slowly, preventing excessive descent from damaging the reverse osmosis membrane 704. The high-pressure pump can be activated when the disc 201 rises to prevent insufficient system pressure, and it stops operating when descending. This intermittent pressure application to the raw water while stirring it reduces the operating time of the high-pressure pump and lowers energy consumption.

[0027] Preferably, the treatment tank 1 includes a tank body 101. A water inlet pipe 102 is fixedly connected to the left side inside the tank body 101 for the entry of raw water. A waste pipe 104 is fixedly connected to the right side inside the tank body 101 for the discharge of wastewater after separation. An upper sealing gasket 103 is fixedly connected to the lower part of the tank body 101. The upper sealing gasket 103 is made of rubber.

[0028] Preferably, the rotating column 3 includes a column body 301 fixedly connected to the lower part of the fixed frame 4. The outer side of the column body 301 is provided with an inclined groove 302 and a spiral groove 303. The beginning and end of the inclined groove 302 and the spiral groove 303 are connected to each other. When the ball 206 is in the spiral groove 303, the column body 301 can drive the ball 206 to make the rotating shaft 205 descend, thereby driving the column 204 to make the disc 201 descend. When it is in the inclined groove 302, it drives the disc 201 to rise.

[0029] Preferably, the fixing frame 4 includes a frame body 401 fixedly connected to the upper part of the inside of the processing barrel 1. A rotating rod 404 is movably connected to the inside of the frame body 401 and the processing barrel 1. The rotating rod 404 can rotate inside the frame body 401 and the barrel 101. A limiting ring 403 is fixedly connected to the lower part of the outer side of the rotating rod 404. The limiting ring 403 is used to limit the position of the rotating rod 404. A driven gear 402 is fixedly connected to the upper part of the outer side of the limiting ring 403. The driven gear 402 meshes with the driving gear 502.

[0030] Preferably, the stirring device 5 includes a variable speed motor 501 fixedly connected to the top of the treatment tank 1. The output end of the variable speed motor 501 is fixedly connected to a drive shaft 503. An active gear 502 is fixedly connected to the upper outer side of the drive shaft 503. An stirring blade 504 is fixedly connected to the middle of the outer side of the drive shaft 503. A spiral guide plate 505 is fixedly connected to the lower outer side of the drive shaft 503. Starting the variable speed motor 501 causes the drive shaft 503 to rotate clockwise, which in turn drives the stirring blade 504 to rotate, facilitating the stirring of the raw water. The spiral guide plate 505 can rotate synchronously, which facilitates the continuous upward pushing of the raw water at the bottom, preventing excessive accumulation of impurities in the raw water on the reverse osmosis membrane 704, and ensuring better separation efficiency of the reverse osmosis membrane 704.

[0031] Preferably, the guide cylinder 6 includes a cylinder 601 fixedly connected to the upper part of the inside of the processing tank 1 and a lifting rod 604 on the top of the lifting plate 2. A limiting block 602 is fixedly connected to the top of the lifting rod 604. A spring 603 is fixedly connected between the cylinder 601 and the limiting block 602. The spring 603 is in a compressed state. The cylinder 601 is movably connected to the limiting block 602 and the lifting rod 604. The limiting block 602 and the lifting rod 604 can move up and down inside the cylinder 601 to guide the lifting of the plate 201. Under the action of the spring 603, the plate 201 can rise more easily.

[0032] Preferably, the bottom cover 7 includes a cover body 701 fixedly connected to the lower part of the treatment tank 1. A flow guide 703 is fixedly connected to the lower part of the cover body 701. A pure water pipe 706 is fixedly connected to the lower part of the inside of the flow guide 703. The pure water pipe 706 is used for the discharge of pure water flowing through the reverse osmosis membrane 704. A backflushing pipe 707 is fixedly connected to the left side of the inside of the flow guide 703. The backflushing pipe 707 is used for the introduction of pure water for backflushing and cleaning the reverse osmosis membrane 704. A lower sealing gasket 705 is fixedly connected to the top of the tank body 101. The reverse osmosis membrane 704 is placed on top of the lower sealing gasket 705. The lower sealing gasket 705 is made of rubber. The cover 701, the reverse osmosis membrane 704 and the lower sealing gasket 705 are internally connected by bolts 702. The lower part of the barrel 101 is provided with a screw groove that matches the bolts 702. By placing the cover 701 at the lower part of the barrel 101 and screwing in the bolts 702, the bottom cover 7 can be fixed, and the reverse osmosis membrane 704 can be pressed between the upper sealing gasket 103 and the lower sealing gasket 705. While fixing the reverse osmosis membrane 704, it can also ensure better sealing between the reverse osmosis membrane 704 and the barrel 101 and the cover 701.

[0033] Preferably, the support 8 includes a fixed sleeve 801 fixedly connected to the outside of the processing tank 1. A support column 802 is fixedly connected to the lower part of the fixed sleeve 801. A fixed block 803 is fixedly connected to the lower part of the support column 802. The fixed block 803 has a fixed hole 804 inside. The fixed block 803 can be fixed on the plane through the fixed hole 804, which makes it easier to ensure better stability when the equipment is running.

[0034] Working Principle: During use, raw water is introduced into the tank 101 through the inlet pipe 102 for separation. Simultaneously, the variable speed motor 501 is activated, causing the drive shaft 503 to rotate clockwise, which in turn drives the stirring blades 504 to rotate, facilitating the stirring of the raw water. The spiral guide plate 505 rotates synchronously, continuously pushing the raw water from the bottom upwards, preventing excessive accumulation of impurities on the reverse osmosis membrane 704, and ensuring better separation efficiency of the reverse osmosis membrane 704. At the same time, the rotation of the drive shaft 503 drives the drive gear 502 to rotate. The drive gear 502 meshes with the driven gear 402, and the rotation of the drive gear 502 causes the driven gear 402 to drive the rotating rod 404 to rotate, which in turn drives the column 301 to rotate counterclockwise. When the ball bearings 206 are in the spiral groove 303, as the column 301 rotates counterclockwise, the column 301 will squeeze the ball bearings 206, causing the rotating shaft 205 to rotate. The column 204 descends, which in turn drives the disc 201 to descend. The descent of the disc 201 allows it to squeeze the raw water, enabling the pure water in the raw water to pass through the reverse osmosis membrane 704, thus allowing the raw water to be separated normally. When the ball bearing 206 is in the inclined groove 302, the disc 201 moves upward to prepare for the next descent. The circumferential length of the inclined groove 302 is much smaller than that of the spiral groove 303, allowing the disc 201 to rise quickly and descend slowly, preventing the reverse osmosis membrane 704 from being damaged by excessively fast descent. When the disc 201 rises, the high-pressure pump can be started to prevent insufficient system pressure, and when it descends, the high-pressure pump stops operating. While stirring the raw water, pressure can be applied to the raw water intermittently, reducing the running time of the high-pressure pump and reducing energy consumption. The pure water flowing through the reverse osmosis membrane 704 flows out through the pure water pipe 706. After use, the waste pipe 104 can be opened to discharge the wastewater.
