Description

[0002] In recent years, with the rapid development of the economy and society, water conservation, energy conservation, emission reduction and pollution reduction have become the consensus of environmental protection. More and more companies have begun to adopt membrane-based water reuse equipment. Water refers to wastewater or rainwater that has been properly treated to meet certain water quality indicators and certain usage requirements and can be used for beneficial purposes. When treating water, reuse equipment is needed to filter out large debris and small particles mixed in it.

The other end of the air supply pipe 11 passes through the cavity 103 and is connected to the air bag 1031. The other end of the drain pipe 1024 is connected to the funnel cavity 104. The bottom of the funnel cavity 104 is connected with a pipe 5. The bottom end of the pipe 5 is connected to the water receiving box 702. Several water receiving boxes 702 are provided with inverted frustum-shaped chambers.

[0034] A solenoid valve 1025 is installed on the drain pipe 1024, and a guide triangle plate 1023 is welded to the bottom of the side wall of the filter chamber 102 located at the water supply pipe 901. The length of the pretreatment box 1 is greater than that of the membrane treatment box 6. Support legs 701 are symmetrically welded on one side of the bottom of the pretreatment box 1. An air supply pipe 803 communicating with the cavity 103 and the air bag 1031 is provided on the side of the bottom of the pretreatment box 1 close to the support legs 701. An air supply valve 8031 ​​is installed on the air supply pipe 803. An annular pressure supply plate 8 is fixed to the upper surface of the water receiving box 702. An air storage cavity 801 is opened inside the pressure supply plate 8. A plurality of air jets 802 communicating with the air storage cavity 801 are evenly provided on the bottom of the pressure supply plate 8. The plurality of air jets 802 all penetrate the wall of the water receiving box 702 and communicate with its interior. The end of the air supply pipe 803 penetrates the support plate 7 and the pressure supply plate 8 in sequence and communicates with the air storage cavity 801.

[0035] A mounting plate 605 is provided inside the membrane treatment box 6, and several reverse osmosis membranes 601 are installed on the lower surface of the mounting plate 605. The tops of the several reverse osmosis membranes 601 are provided with water inlet pipes 6011 that pass through the mounting plate 605. The tops of the several water inlet pipes 6011 are communicated with the water receiving box 702. A water collecting plate 603 is installed on the inner bottom plate of the membrane treatment box 6. A chamber is opened inside the water collecting plate 603. The bottom ends of the several reverse osmosis membranes 601 are connected to the downpipes 602.

The outlet pipe 604 passes through the wall of the membrane treatment box 6 and extends to the outside. The outer wall of the mounting plate 605 is snap-connected with the inner wall of the membrane treatment box 6. The water collecting plate 603 is arranged in a circular shape, and the diameter of the water collecting plate 603 is smaller than the diameter of the mounting plate 605.

[0036] When reusing reclaimed water, the staff starts the water supply pump 9 through the control panel 10. The water supply pump 9 sends the raw water into the filter chamber 102 in the pretreatment box 1 through the water supply pipe 901. At this time, the solenoid valve 1025 of the drain pipe 1024 is in a closed state. The water entering the filter chamber 102 passes through the first filter screen 1021 and the second filter screen 1022 under the action of pressure to filter impurities. At the same time, the air originally existing in the filter chamber 102 is squeezed into the air supply pipe 11 through the exhaust component 4. The air enters the air bag 1031 in the cavity 103 through the air supply pipe 11, and the air bag 1031 begins to expand. As more and more water enters, more air is squeezed out, and the air bag 1031 also expands larger and larger. At this time, the exhaust component 4 will press the air supply pipe 1 under the action of water. 1 is blocked, and at this time the control panel 10 opens the solenoid valve 1025. The filtered water enters the funnel cavity 104 through the drain pipe 1024 and enters the water receiving box 702 through the pipe 5 under gravity. Then, under the action of gravity, it is diverted through several water inlet pipes 6011 and enters several reverse osmosis membranes 601 in the membrane treatment box 6 for filtration treatment. In the water receiving box 702, the air supply valve 8031 ​​on the air supply pipe 803 will be opened briefly from time to time, and the air in the air bag 1031 will enter the water receiving box 702 through the air supply pipe 803. The incoming air will increase the internal pressure, so as to play the role of auxiliary pressure supply. The water filtered by the reverse osmosis membrane 601 will enter the chamber in the water collecting plate 603 through the downpipe 602 and be discharged from the outlet pipe 604.

[0037] Therefore, the present application can effectively reduce the floor space by vertically stacking the pretreatment box 1 and the membrane treatment box 6. At the same time, a water supply pump 9 can be used to directly perform subsequent membrane treatment after pretreatment of the raw water, eliminating the need for secondary pressurization. The membrane treatment uses a reverse osmosis membrane 601 with a high permeation flux, and a large flux can be achieved at low pressure, thereby reducing the use of the pump body, significantly reducing the power consumption of the equipment operation, and reducing the potential for failure.

[0038] See also Figure 2-4 As shown, the exhaust assembly 4 includes a sleeve 401, in which a blocking ball 402 is movably disposed. Guide arc plates 403 are integrally connected to both sides of the outer wall of the sleeve 401. Air inlet holes 404 are formed on the two guide arc plates 403 and the top of the outer wall of the sleeve 401. The top of the sleeve 401 is fixedly connected to the top wall of the filter cavity 102, and the length of the sleeve 401 is less than the height of the filter cavity 102. The blocking ball 402 is made of a relatively light material and can float on water.

[0039] When water enters the filter chamber 102, the water filtered by the first filter screen 1021 and the second filter screen 1022 will push the blocking ball 402 to float. As the water level rises, the blocking ball 402 will also rise along the inner wall of the sleeve 401 along with the water level. At this time, the air in the filter chamber 102 enters the air pipe 11 through the air inlet 404 under the rising water level. When the blocking ball 402 is lifted to the bottom of the air pipe 11, the blocking ball 402 will block the air pipe 11 to prevent water from entering the air pipe 11.

[0040] See also Figure 2 、 Figure 3 and 7 As shown, the cleaning component 3 includes a horizontal plate 301 arranged at the bottom of one side of the first filter 1021 and the second filter 1022, and a cleaning brush 3011 is fixed on one side of the two horizontal plates 301 close to the first filter 1021 and the second filter 1022. The wall bodies on both sides of the filter chamber 102 are located at the ends of the horizontal plate 301 and are provided with grooves 302. A pull rod 303 is provided in each groove 302. The bottom end of each pull rod 303 is welded to the end of the horizontal plate 301, and the top of each pull rod 303 passes through the top wall of the pretreatment box 1 and is fixedly connected to a lifting plate 304. Both sides of the lifting plate 304 are in contact with the side walls of the L-shaped protective shell 2 and are slidably connected. The L end of the L-shaped protective shell 2 is connected to the pretreatment box 1. The side walls of the box 1 are in contact with each other, and an electric telescopic cylinder 308 is fixedly installed on the inner wall of the side of the L-shaped protective shell 2 away from the L end. The telescopic end of the electric telescopic cylinder 308 is fixedly connected to a scraper 309. A threaded hole 3041 is provided at the center of the lifting plate 304. A driving motor 307 is installed on the top of the L-shaped protective shell 2 by a bolt. The output end of the driving motor 307 passes through the wall of the L-shaped protective shell 2 and is fixedly connected to a threaded rod 306. The threaded rod 306 is threadedly connected to the threaded hole 3041. There is a gap between the bottom of the threaded rod 306 and the top wall of the pretreatment box 1. The height of the scraper 309 is less than the gap between the threaded rod 306 and the pretreatment box 1. A sealing door 201 is installed on the outer wall of the L top end of the L-shaped protective shell 2;

[0041] The two cleaning brushes 3011 are in contact with the first filter 1021 and the second filter 1022, the outer wall of each pull rod 303 is in contact with the inner wall of the groove 302, and a stopper 305 is welded between the tops of each two pull rods 303. The two stoppers 305 are slidably arranged in the top wall of the pretreatment box 1.

[0042] When the raw water passes through the first filter 1021 and the second filter 1022, impurities will be filtered out. In order to prevent the impurities from blocking the meshes of the first filter 1021 and the second filter 1022, the water supply pump 9 is stopped every once in a while. At this time, the driving motor 307 in the cleaning component 3 works, and the electric threaded rod 306 at the output end of the driving motor 307 rotates. The rotating threaded rod 306 causes the lifting plate 304 to move vertically along the inner wall of the L-shaped protective shell 2. The moving lifting plate 304 drives the pull rod 303 and the stop block 305 to move. The multiple pull rods 303 drive the two horizontal plates 301 to rise along the groove 302. The two rising horizontal plates 301 drive the cleaning brush 3011 to move upward. During the process, the impurities attached to the first filter 1021 and the second filter 1022 are cleaned off respectively, and the impurities are pushed up together until the cleaning brush 3011 pushes the impurities into the L-shaped protective shell 2. At this time, the electric telescopic cylinder 308 works, and its telescopic end pushes the scraper 309 to move. The moving scraper 309 pushes the impurities attached to the removed cleaning brush 3011 and the impurities accumulated on the top of the box toward the L end, so that the impurities fall into the inside of the L end, which is convenient for the staff to handle by opening the sealing door 201. After the cleaning is completed, the electric telescopic cylinder 308 contracts to drive the scraper 309 to reset, and then the drive motor 307 is reversed to reset the horizontal plate 101 and the cleaning brush 3011, and then continue the reclaimed water reuse treatment.

[0043] The working principle of the present invention is:

[0044] When reusing reclaimed water, the staff starts the water supply pump 9 through the control panel 10. The water supply pump 9 sends the raw water into the filter chamber 102 in the pretreatment box 1 through the water supply pipe 901. At this time, the solenoid valve 1025 of the drain pipe 1024 is in a closed state. The water entering the filter chamber 102 passes through the first filter screen 1021 and the second filter screen 1022 under the action of pressure to filter impurities. At the same time, the air originally existing in the filter chamber 102 is squeezed into the air supply pipe 11 through the exhaust component 4. The air enters the air bag 1031 in the cavity 103 through the air supply pipe 11, and the air bag 1031 begins to expand. As more and more water enters, more air is squeezed out, and the air bag 1031 also expands larger and larger. At this time, the exhaust component 4 will press the air supply pipe 1 under the action of water. 1 is sealed, and at this time the control panel 10 opens the solenoid valve 1025, and the filtered water enters the funnel cavity 104 through the drain pipe 1024, and enters the water receiving box 702 through the pipe 5 under gravity, and then is diverted through several water inlet pipes 6011 under the action of gravity to enter several reverse osmosis membranes 601 in the membrane treatment box 6 for filtration treatment, wherein in the water receiving box 702, the air supply valve 8031 ​​on the air supply pipe 803 will be opened briefly from time to time, and the air in the air bag 1031 will enter the water receiving box 702 through the air supply pipe 803. The incoming air will increase the internal pressure so as to play an auxiliary pressure supply effect, and the water filtered by the reverse osmosis membrane 601 will enter the chamber in the water collecting plate 603 through the downpipe 602, and be discharged from the water outlet pipe 604.
