Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a modular high-salt reverse osmosis concentrated water treatment integrated device. Background Technology

[0002] With the rapid development of industry and the increasing prominence of water scarcity, reverse osmosis technology has been widely used in the field of water treatment. However, the reverse osmosis process produces a large amount of concentrated water with high salinity. If discharged directly, it will not only waste water resources but also cause serious pollution to the environment.

[0003] Existing concentrated wastewater treatment processes include pretreatment, desalination, concentration, and water storage. Currently, the water treatment equipment in the pretreatment process has many shortcomings. On the one hand, traditional pretreatment equipment is often complex in structure, with cumbersome connections between treatment units, making installation and maintenance difficult and hindering rapid deployment and subsequent repairs. On the other hand, most existing equipment occupies a large area, which greatly limits its application in spaces with limited space. Furthermore, during the initial filtration of concentrated wastewater in the pretreatment process, the filtration efficiency is affected as impurities gradually increase.

[0004] Therefore, developing a high-salt reverse osmosis concentrate treatment equipment that is easy to install and maintain, occupies a small area, and has high-efficiency filtration is of great practical significance. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a modular high-salt reverse osmosis concentrate treatment integrated equipment that is easy to install and maintain, saves land space, and improves treatment efficiency, thus effectively solving the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular high-salt reverse osmosis concentrate treatment integrated equipment, including a box body, with a longitudinal partition plate on the inner side of the box body and a transverse partition plate on the side of the longitudinal partition plate. The longitudinal partition plate and the transverse partition plate divide the interior of the box body into a first chamber, a second chamber and a third chamber. A filtration module is provided in the first chamber, a flocculation module is provided in the second chamber, and a sedimentation module is provided in the third chamber.

[0007] The top of the diaphragm is provided with a guide channel connecting the first chamber and the second chamber. The bottom of the inner wall of the third chamber is provided with a manifold. Water distribution pipes are evenly provided on the side of the manifold. Water inlet holes are provided on the water distribution pipes.

[0008] A drainage pump is provided on the side of the box. The input end of the drainage pump is connected to the second chamber through a drainage pipe, and the output end of the drainage pump is connected to the manifold.

[0009] The bottom of the third chamber is provided with a sludge collection trough, the cross-section of which is triangular, and the bottom of which is provided with a sludge discharge pipe, the end of which penetrates the side of the box body.

[0010] The filtration module is used for preliminary filtration of concentrated water, the flocculation module is used for mixing concentrated water with flocculant, and the sedimentation module is used for removing suspended solids from the concentrated water.

[0011] Furthermore, the filter module includes a grid located on the top side inside the first chamber. A collection groove is provided on one side of the grid, and a through groove is provided on the side of the collection groove. A detection plate is provided on the top of the grid, and a level gauge is provided on the detection plate. A magnetic seat is provided on the top of the detection plate.

[0012] Furthermore, a guide rod is provided on the side of the detection plate, the guide rod passes through the side of the transverse partition, and a spring is sleeved on the guide rod.

[0013] Furthermore, the flocculation module includes a frame base, which is slidably connected between the inner walls of the second chamber. A slide block is slidably connected to the top of the frame base, and a stirring rod is rotatably connected to the bottom of the slide block. A motor is provided on the top of the slide block, and the output shaft of the motor is fixedly connected to the end of the stirring rod.

[0014] Furthermore, a first electric push rod is provided between the side of the frame base and the inner wall of the box, and a second electric push rod is provided on the inner wall of the frame base. The telescopic end of the second electric push rod is fixedly connected to the slide, and an electromagnetic seat is provided on the side of the frame base.

[0015] Furthermore, the sedimentation module includes an inclined tube assembly, an overflow weir, and a drain outlet. The inclined tube assembly is mounted inside the third chamber via a support. The overflow weir is located on the inner wall of the third chamber and above the inclined tube assembly. The drain outlet is located on the side of the tank and is connected to the overflow weir.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. The equipment in this application adopts a modular design. The housing is divided into three chambers with integrated filtration, flocculation and sedimentation functions by longitudinal and transverse partitions. Each treatment unit is built into the same housing, which reduces the complicated connection pipelines between units in traditional equipment and simplifies the overall structure. This integrated structure eliminates the need for complicated on-site assembly during equipment installation and allows for individual operation of a single module during later maintenance, reducing the difficulty of maintenance and facilitating rapid deployment and subsequent maintenance.

[0018] 2. The filtration module of this application is equipped with a level gauge and an automatic cleaning mechanism. When the screen becomes clogged due to the accumulation of impurities, the level gauge can detect the rise in liquid level in real time. At this time, the electromagnetic seat and the magnetic seat cooperate to drive the detection plate to reciprocate through the guide rod and spring, pushing the impurities on the screen surface into the collection tank to achieve automatic cleaning. This avoids the trouble of frequent manual cleaning, effectively prevents screen clogging from affecting filtration efficiency, and ensures the continuity and stability of concentrated water treatment.

[0019] 3. The flocculation module of this application drives the stirring rod to move in multiple dimensions in the horizontal direction through the first electric push rod and the second electric push rod. Combined with the stirring action driven by the motor, the stirring range is expanded, making the concentrated water and flocculant mix more evenly and enhancing the flocculation reaction effect.

[0031] The first chamber is equipped with a filter module 2, which is used for preliminary filtration of concentrated water. The filter module 2 includes a grid 201, which is located on the top side of the interior of the first chamber. A collection tank 202 is provided on one side of the grid 201, and a through groove is opened on the side of the collection tank 202. A detection plate 203 is provided on the top of the grid 201, and a level gauge 204 is provided on the detection plate 203. A magnetic seat 205 is provided on the top of the detection plate 203. A guide rod 206 is provided on the side of the detection plate 203, and the guide rod 206 passes through the side of the transverse partition 102. The collection tank 202 is used to collect impurities intercepted by the grid 201. A spring 207 is sleeved on the guide rod 206. The level gauge 204 is used to detect the liquid level above the grid 201.

[0032] The second chamber is equipped with a flocculation module 3, which is used to mix concentrated water with flocculant. The flocculation module 3 includes a frame base 301, which is slidably connected between the inner walls of the second chamber. A slide block 302 is slidably connected to the top of the frame base 301, and a stirring rod 303 is rotatably connected to the bottom of the slide block 302. A motor 304 is provided on the top of the slide block 302. The output shaft of the motor 304 is fixedly connected to the end of the stirring rod 303. A stirring blade is provided on the stirring rod 303. The stirring rod 303 drives the stirring blade to rotate for mixing concentrated water and flocculant.

[0033] A first electric push rod 305 is provided between the side of the frame base 301 and the inner wall of the housing 1. A second electric push rod 306 is provided on the inner wall of the frame base 301. The telescopic end of the second electric push rod 306 is fixedly connected to the slide 302. The first electric push rod 305 is used to drive the frame base 301 to slide, and the second electric push rod 306 is used to drive the slide 302 to slide.

[0034] An electromagnetic seat 307 is provided on the side of the frame 301. The electromagnetic seat 307 corresponds to the magnetic seat 205 and uses magnetic force to drive the detection plate 203 to move.

[0035] The third chamber is equipped with a sedimentation module 4, which is used to remove suspended solids from the concentrate. The sedimentation module 4 includes an inclined tube assembly 402, an overflow weir 403, and a drain outlet 404. The inclined tube assembly 402 is installed inside the third chamber via a support 401. The overflow weir 403 is located on the inner wall of the third chamber and above the inclined tube assembly 402. The drain outlet 404 is opened on the side of the housing 1 and is connected to the overflow weir 403.

[0036] In use, the concentrated water generated by reverse osmosis is introduced from the top of the first chamber. After passing through the grid 201, the concentrated water enters the first chamber and is filtered by the grid 201 to remove large-volume impurities and floating objects. As the liquid level of the concentrated water in the first chamber gradually rises, when the liquid level reaches the lower edge of the guide channel 1021, it enters the second chamber through the guide channel 1021. During this process, small-volume, high-weight impurities that have passed through the grid 201 are trapped in the first chamber, achieving further impurity removal.

[0037] After the concentrated water enters the second chamber and reaches the specified liquid level, flocculant is added to the second chamber. The flocculant is preferably polyaluminum chloride. At the same time, the motor 304 is started to drive the stirring rod 303 and stirring blade to rotate slowly. The first electric push rod 305 drives the frame seat 301 to reciprocate linearly, and the second electric push rod 306 drives the slide seat 302 to reciprocate linearly, thereby expanding the stirring range of the stirring rod 303 in the second chamber, so that the flocculant and concentrated water are fully mixed and the mixing uniformity is improved.

[0038] After the flocculant and concentrated water are mixed, the electric valve is turned on, and the mixture of flocculant and concentrated water is drawn out through the drainage pipe 108 by the drainage pump 107 and pumped into the manifold 103 through the output end of the drainage pump 107. Finally, it enters the third chamber through the water distribution pipe 104. The mixture of flocculant and concentrated water reacts and precipitates at the bottom of the third chamber, removing suspended solids from the concentrated water. The sludge produced by flocculation falls into the sludge collection tank 105 for sedimentation and collection. At the same time, as the liquid level in the third chamber continues to rise, the concentrated water after flocculation reaction is further purified after passing through the inclined tube assembly 402. The resulting clean water moves upward through the top of the inclined tube assembly 402 and overflows after the clean water level reaches the overflow weir 403. It is then discharged into the next process for further treatment through the drain outlet 404.

[0039] As the concentrated wastewater continues to be processed, more and more impurities accumulate on the screen 201, causing it to become clogged and reducing its flowability. This leads to a rise in the concentrated wastewater level on the screen 201. When the level gauge 204 detects that the concentrated wastewater level on the screen 201 is higher than the set threshold, it indicates that the screen 201 is clogged. At this point, the electromagnetic base 307 is energized to generate magnetism. The first electric push rod 305 drives the frame base 301 and the electromagnetic base 307 towards the magnetic base 205. The electromagnetic base 307 and the magnetic base 205 then... The magnetic repulsion force generated between the five points drives the detection plate 203 to slide horizontally. The bottom of the detection plate 203 contacts the surface of the grid 201, pushing the impurities accumulated on the surface of the grid 201 into the collection groove 202. At the same time, the spring 207 is elastically compressed. At this time, the reciprocating extension and retraction of the first electric push rod 305 drives the frame base 301 to reciprocate. Under the action of the spring 207, the detection plate 203 reciprocates, realizing continuous cleaning of the surface of the grid 201, ensuring the flow of the grid 201, and improving the processing efficiency.
