[0050] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0051] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0052] A reverse osmosis ultrafiltration water treatment device provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0053] Embodiment 1:

[0054] Combination Figure 1-Figure 12 As shown, a reverse osmosis ultrafiltration water treatment equipment provided by the present invention includes a transmission mechanism 200 and a liquid boosting mechanism 100, the transmission mechanism 200 is arranged on the liquid boosting mechanism 100, a slag discharge mechanism 300 is arranged at the bottom of the liquid boosting mechanism 100, a primary filtration mechanism 500 is arranged at the top of the liquid boosting mechanism 100, and a solid-liquid separation mechanism 400 is arranged in the liquid boosting mechanism 100.

[0055] The liquid boosting mechanism 100 includes a pressure-resistant outer chamber 110 and two flow guide pipes 120 installed at the bottom of the pressure-resistant outer chamber 110;

[0056] A water inlet pipe 130 and an external pipe 140 connected to the water inlet pipe 130 are installed on the top of the pressure-resistant outer chamber 110;

[0057] A first sealing groove 150 is formed at the top of the pressure-resistant outer chamber 110, a second sealing groove 160 is formed at the bottom of the pressure-resistant outer chamber 110, and an annular groove 170 is formed on the inner side of the bottom of the pressure-resistant outer chamber 110;

[0058] The transmission mechanism 200 is used to provide kinetic energy for squeezing the sewage in the inner cavity of the pressure-resistant outer chamber 110 and emptying the impurities;

[0059] The transmission mechanism 200 includes two sets of clamping seats 210 installed on the outer wall of the pressure-resistant outer chamber 110, hydraulic rods 220 installed in the two sets of clamping seats 210, and a support plate 230 connected to the top of the hydraulic sub-rod in the hydraulic rod 220;

[0060] The extended vertical rod passes through the column head outside the top cover 510 and is adapted to be inserted into the hole at the other end of the support plate 230;

[0061] The slag discharge mechanism 300 includes a bottom bin 310 disposed at the bottom end of the pressure-resistant outer bin 110, a middle filter assembly 350 disposed inside the bottom bin 310, a first sealing gasket 320 disposed at the top end of the bottom bin 310, an auxiliary pressure pad 330 installed at the top of the bottom bin 310, and a dirt discharge pipe 340 connected to the outer end pipe of the bottom bin 310;

[0062] The outer end of the dirt discharge pipe 340 is connected to an external sewage tank, and the middle filter assembly 350 is used to guide the discharge of solid impurities;

[0063] The solid-liquid separation mechanism 400 includes a liquid blocking end head 430 disposed outside the middle filter assembly 350 and located in the inner cavity of the pressure-resistant outer chamber 110, a slag discharge end pipe 440 installed at the bottom of the liquid blocking end head 430, a tension spring 450 connected to the top of the slag discharge end pipe 440 and located in the inner cavity of the liquid blocking end head 430, and a sealing gasket 460 connected to the top of the tension spring 450 and under pressure in the port of the liquid blocking end head 430;

[0064] The primary filter mechanism 500 includes a top cover 510 disposed on the top of the pressure-resistant outer chamber 110, an annular cover 540 disposed in the top cover 510, an ultrafiltration mesh pad 560 disposed in the annular cover 540, a drain pipe 520 installed on the top cover 510, and a second sealing pad 530 disposed at the bottom end of the top cover 510;

[0065] The port at the outer end of the drain pipe 520 is connected to the water inlet pipe of the ultrafiltration device.

[0066] When traditional reverse osmosis ultrafiltration water treatment equipment treats sewage, the components of the water treatment equipment for initial sewage treatment need to be cleaned regularly, and the equipment needs to be shut down for cleaning. At this time, the components for initial sewage filtration need to be disassembled and repaired and cleaned. At the same time, the sewage is transferred from top to bottom, and the solid impurities inside the sewage will impact the initial filtration components under the action of water pressure. In severe cases, the initial filtration components will be damaged, which will lead to a lower solid-liquid separation efficiency.

[0067] At the same time, the corrosive dirt in the sewage adheres to the inner wall of the equipment, which will cause corrosion of the inner wall of the equipment over a long period of time, thereby increasing the metal content in the sewage.

[0068] When the external pipe 140 injects sewage into the inner cavity of the pressure-resistant outer chamber 110, the plugging end 430 disposed in the inner cavity of the pressure-resistant outer chamber 110 and used for pressurized sewage can quantitatively store the sewage to be treated. When the sewage is filled to the same level as the bottom surface of the ultrafiltration pad 560, the rising plugging end 430 will squeeze the sewage upward, and finally the solid impurities in the sewage will not directly impact the ultrafiltration pad 560 due to the impact of water pressure. As the sewage is squeezed upward, the sewage will eventually pass through the ultrafiltration pad 560 and flow into the pipe of the external ultrafiltration device, while the solid impurities at the bottom will accumulate in the plugging end 430.

[0069] When the liquid blocking end 430 falls downward along the sewage inner pipe 351 until the slag discharge end pipe 440 pushes the plug pad 353 to extend downward, the end column 354 can squeeze the sealing pad 460 upward, and the solid impurities accumulated in the liquid blocking end 430 can quickly enter the cavity formed by the sewage inner pipe 351 and the plug pad 353 under the pressure of part of the sewage, and finally the solid impurities and part of the sewage can be discharged into the external sewage tank through the scale discharge pipe 340. After the liquid blocking end 430, which is lifted in an instant, is evacuated from the top of the auxiliary pressure pad 330, the sealing pad 460 will be quickly reset under the action of water pressure and the tension spring 450, so as to continue to squeeze out the sewage in the above manner.

[0070] Embodiment 2:

[0071] Combination Figure 4-Figure 12 As shown, on the basis of Example 1, the middle filter assembly 350 includes a sewage inner pipe 351 fixedly installed inside the bottom bin 310, and the sewage inner pipe 351 as a whole is composed of a cylindrical bottom pipe and a beam pipe, and the cylindrical bottom pipe is provided with symmetrically distributed notches;

[0072] The inner cavity of the sewage inner tube 351 is connected with a reinforcing spring 352, the top of the reinforcing spring 352 is connected with a plugging pad 353, and the plugging pad 353 is movably installed in the cylindrical bottom tube, and the middle of the cylindrical bottom tube is installed with an end column 354, and the end column 354 is adapted to penetrate into the plugging pad 353, and the top of the sewage inner tube 351 is installed with a plug 355;

[0073] Symmetrically distributed slide grooves are provided on both sides of the beam tube;

[0074] The liquid blocking end 430 is in a funnel-shaped structure as a whole, and evenly distributed slots are provided in the inclined surface inside the liquid blocking end 430, and holes for draining impurities are provided in the inner wall of the liquid blocking end 430;

[0075] The two clamping plates at the top of the liquid blocking end 430 are both movably mounted with inclined frames 420, and the two inclined frames 420 are connected with traction members 410;

[0076] The traction member 410 is composed of an extended vertical rod, a scraper head and a clamping seat, and two inclined frames 420 are connected to the clamping seat, and the scraper head is adapted to fit in the inner wall of the beam tube;

[0077] The top and bottom ends of the liquid blocking end 430 are provided with cutting edges, and both cutting edges are adapted to fit the inner wall of the pressure-resistant outer chamber 110;

[0078] The two cutting edges in the liquid blocking end 430 are used to clean the corrosive dirt on the inner wall of the pressure-resistant outer chamber 110;

[0079] The pipe wall of the liquid blocking end 430 is provided with a communicating hole groove and a port for discharging solid impurities.

[0080] By operating the hydraulic rod 220, as the hydraulic sub-rod in the hydraulic rod 220 rises and falls, the traction member 410 connected through the support plate 230 will pull the liquid blocking end head 430 as a whole to rise and fall at a uniform speed along the inner wall of the pressure-resistant outer chamber 110, and the two blades in the liquid blocking end head 430 can scrape off the dirt attached to the inner wall of the pressure-resistant outer chamber 110, wherein the scraped dirt will accumulate inside the liquid blocking end head 430 under the impact of sewage and solid impurities, and after operating according to the above steps, the corrosive dirt will also be discharged at the same time when the solid impurities are discharged into the inner cavity of the bottom chamber 310;

[0081] As the traction member 410 reciprocates and rises and falls along the inner cavity of the sewage inner pipe 351, the scraper head in the traction member 410 can stably scrape the inner wall of the beam tube in the sewage inner pipe 351. At this time, the dirt attached to the inner wall of the beam tube can be scraped off by the scraper head. At this time, the device can provide anti-corrosion protection for the component pipe wall without stopping operation, thereby improving the safety of the initial filtration of sewage.

[0082] Embodiment 3:

[0083] Combination Figure 7-Figure 12 As shown, on the basis of Example 1, a pressure-bearing cushion 550 is provided at the bottom end of the inner cavity of the top cover 510, and the pressure-bearing cushion 550 is composed of a plurality of end rods and a positioning cover, and a scraper 570 is movably installed in the positioning cover;

[0084] The scraper 570 is composed of a T-shaped shaft sleeve, a plurality of evenly distributed blades and a plurality of evenly distributed scrapers, and the plurality of evenly distributed scraper blade edges are adapted to fit the bottom surface of the ultrafiltration mesh pad 560 .

[0085] By movably installing the scraper 570 in the hydraulic rod 220, as the blocking end 430 applies pressure to the sewage upward, the sewage can push the evenly distributed blades before passing through the ultrafiltration pad 560 until the scraper 570 rotates. At the same time, the evenly distributed multiple scrapers can obtain kinetic energy to assist the rotation, and some dirt attached to the bottom surface of the ultrafiltration pad 560 can be continuously cleaned by the evenly distributed multiple scrapers. At this time, the ultrafiltration pad 560 can treat the sewage in a highly efficient filtering manner, and can reduce the blockage of the mesh of the ultrafiltration pad 560 caused by excessive dirt attachment, while reducing the water pressure and the damage of the ultrafiltration pad 560 to the solid impurities.

[0086] Embodiment 4:

[0087] Combination Figure 10-12 As shown, in the above embodiment, the slag discharge end pipe 440 is composed of a cross-shaped clamp and a U-shaped pipe, and a portion connected to the U-shaped pipe is opened in the middle of the cross-shaped clamp, and the U-shaped pipe is located inside the beam pipe.

[0088] The U-shaped pipe is used to push the plug pad 353 downward. At this time, the upward thrust given to the plug pad 353 by the reinforcing spring 352 is greater than the water pressure of the sewage. At this time, the plug pad 353 in the initial state can effectively block the cylindrical bottom pipe. When the U-shaped pipe is pressurized and pushes the plug pad 353 downward, the pressure exceeding the pressure range of the reinforcing spring 352 can cause the U-shaped pipe to extend into the inner cavity of the cylindrical bottom pipe. At this time, the groove opened in the U-shaped pipe can smoothly transfer the solid impurities accumulated inside the liquid blocking end 430 to the cavity formed by the cylindrical bottom pipe and the plug pad 353. Finally, under the impact of some sewage, the solid impurities can be smoothly transferred from the bottom bin 310 to the scale discharge pipe 340, thereby effectively ensuring that the solid impurities and part of the sewage are discharged into the external sewage tank.

[0089] The working principle and use process of the present invention are as follows: when the ultrafiltration water treatment equipment is treating sewage, the gravel and other particles mixed in the sewage will cause blockage to the pipeline of the ultrafiltration water treatment equipment. Therefore, after treating the water for a period of time, workers are required to remove the primary filter component from the water treatment equipment and empty the gravel and other particles inside it. In addition, the frequent loading and unloading of the filter gravel and other particle components at intervals makes the filter component susceptible to contamination by external dirt, and at the same time affects the continuity of the equipment in treating sewage.

[0090] The device sets the traditional filter components for crushed stones and other particles to clean the impurities autonomously. When the external pipe 140 is connected to the sewage pipe, and the drain pipe 520 is connected to the ultrafiltration water treatment pipeline, and then the scale pipe 340 is connected to the sewage tank, the device can be placed between the sewage and the subsequent ultrafiltration components;

[0091] As the external pipe 140 continues to inject sewage, the sewage will enter the cavity between the pressure-resistant outer chamber 110 and the liquid blocking end 430 under the drainage of the water inlet pipe 130. At this time, the sewage continues to increase until the sewage in the inner cavity of the pressure-resistant outer chamber 110 is filled with the bottom of the ultrafiltration pad 560, and then the hydraulic rod 220 needs to be operated. As the hydraulic sub-rod in the hydraulic rod 220 is lifted upward, the support plate 230 fixed on the top of the hydraulic sub-rod can drive the traction member 410 is lifted upward at a uniform speed along the inner cavity of the sewage inner pipe 351. At this time, the liquid blocking end 430 connected to the traction member 410 through two inclined frames 420 can pressurize and squeeze the sewage in the inner cavity of the pressure-resistant outer chamber 110 into the ultrafiltration mesh pad 560. Finally, the solution squeezed out from the mesh of the ultrafiltration mesh pad 560 can be transferred from the drainage pipe 520 to the ultrafiltration pipeline system, and the gravel and other particles in the sewage can be stored in its inner cavity through the notch at the top of the liquid blocking end 430.

[0092] As the hydraulic sub-rod contracts downward until the plugging end 430 is pressurized and drops to the bottom of the auxiliary pressure pad 330, the slag discharge end pipe 440 can squeeze the plug pad 353 pressed in the inner cavity of the sewage discharge inner pipe 351 downward until the inner cavity of the slag discharge end pipe 440 is connected with the cavity at the bottom end of the sewage discharge inner pipe 351, and the top of the end column 354 can push the sealing pad 460 to stretch upward. At this time, the cavity above the plugging end 430 will be connected with the cavity at the bottom end of the sewage discharge inner pipe 351. As the external pipeline 140 continues to inject sewage, the inflowing sewage can quickly flush the gravel and other particles stored in the plugging end 430 into the cavity at the bottom end of the sewage discharge inner pipe 351. Finally, the gravel and other particle impurities can be transferred from the gap formed by the sewage discharge inner pipe 351 and the plug pad 353 to the bottom of the bottom bin 310, and finally the gravel and other particle impurities can be discharged from the descaling pipe 340 into the sewage pool without separating the sewage;

[0093] When the above operation forms a closed loop, the hydraulic sub-rod can drive the liquid blocking end 430 to lift upward from the top of the auxiliary pressure pad 330 until a sufficiently safe gap is maintained between the liquid blocking end 430 and the auxiliary pressure pad 330. At this time, the sealing gasket 460 is pulled by the tension spring 450 and can be pressed against the port of the inner cavity of the liquid blocking end 430. At this time, the liquid blocking end 430 and the sealing gasket 460 in a sealed state can quickly separate impurities such as particulate matter in the sewage without stopping the equipment, thereby improving the efficiency of ultrafiltration water treatment.

[0094] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
