Description

Technical Field

[0001] This utility model relates to the field of concentrate recovery and utilization technology, specifically a reverse osmosis concentrate recovery and utilization device. Background Technology

[0002] Reverse osmosis is a highly efficient and clean desalination technology widely used in various industries. However, during the production process, approximately 25% of the total influent water is discharged as concentrated water. This results in a significant waste of water resources in today's increasingly scarce water situation and seriously hinders the further promotion of reverse osmosis technology.

[0003] Chinese Patent CN214319755U discloses a reverse osmosis concentrate recovery and utilization device, belonging to the field of reverse osmosis equipment. The device includes a tank with a liquid outlet fixedly installed on the lower outer wall of the tank's center. A valve is fixedly installed inside the liquid outlet. Base plates are movably installed at the four corners of the lower outer wall of the tank. Wheels are movably installed inside the center of the base plates. Slots A and B are installed inside the outer sides of the wheels and base plates, respectively. Insert plates are inserted into slots A and B. Slides are installed on the four sides of the lower side of the tank, with sliding plates sliding inside each slide. Through grooves are installed on the outer walls of the slides, and connecting plates are fixedly connected to the outer ends of the sliding plates through the through grooves. By incorporating an elastic telescopic structure, an embedded fixing structure, and a rotating structure, the practicality of the utilization device is improved.

[0004] The existing technical solutions described above have the following drawbacks: When moving the tank, it is necessary to pull outwards the two sets of fixing plates A to separate the insert plate from the wheel. However, since the fixing plates A or the outer side of the insert plate are mounting and fixing components, when moving the tank, the user needs to keep pulling the two sets of fixing plates A to ensure that the insert plate does not contact the wheel. Furthermore, when using the insert plate to fix the wheel, the slot A opened on the outer side of the wheel needs to be aligned with the insert plate before the insert plate can be inserted into the slot A. However, since the wheel is installed in the base plate, the position of the slot A is not easy to observe, making it difficult to conveniently insert the insert plate into the slot A. To address the above issues, a technical innovation is proposed based on the existing reverse osmosis concentrate recovery and utilization device. Utility Model Content

[0005] The purpose of this invention is to provide a reverse osmosis concentrate recovery and utilization device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a reverse osmosis concentrate recovery and utilization device, comprising:

[0007] The concentrate recovery tank has a set of first connecting frames on both its left and right sides. Support feet and third springs are evenly distributed at the bottom of each first connecting frame. Anti-slip pads are placed on the bottom of each support foot. A second connecting frame is placed on the outer side of each support foot. Pins and second springs are evenly distributed on the side of the second connecting frame near the support foot. An installation groove is formed on the side of the pin near the support foot. A roller is rotatably mounted in the installation groove via a rotating shaft. An arc-shaped positioning groove and a locking groove are formed on the outer side of each support foot. The roller is located in the arc-shaped positioning groove, and the pin and roller correspond to the locking groove.

[0008] Preferably, the arc-shaped positioning groove is located above the locking groove, and a set of support frames is provided on both the left and right sides of the concentrate recovery tank. The first connecting frame is located above the support frame, the third spring is located on the outer ring of the support foot and is fixedly disposed between the first connecting frame and the support frame, the second connecting frame is located on the outer side of the support frame, and the second spring is located on the outer ring of the pin and is fixedly disposed between the second connecting frame and the support frame.

[0009] Preferably, the top of the support frame has a first through hole evenly distributed through it, the inner wall of the first through hole has a second through hole distributed through it, the bottom of the support foot is connected to the anti-slip pad through the first through hole, and the pin and roller are inserted into the second through hole.

[0010] Preferably, the bottom of the concentrate recovery tank is evenly provided with casters, and the bottom casters of the anti-slip mat are flush with each other.

[0011] Preferably, the top of the anti-slip pad is provided with a screw, and a positioning hole is provided on the outer side of the screw.

[0012] Preferably, the bottom of the support foot is provided with a threaded hole, the screw is screwed into the threaded hole, the inner side wall of the threaded hole is provided with a mounting hole, a first spring is provided in the mounting hole, a round-headed pin is provided on the outer side of the first spring, the round head of the round headed pin is magnetically attracted to a magnetic block, the round head of the round headed pin is inserted into the positioning hole, and the magnetic block is magnetically attracted to the positioning hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In this invention, by pulling the first connecting frame upward to separate the anti-slip pad from the ground, the pin can be automatically inserted into the locking groove by the second spring, thereby automatically locking the support foot. This makes it convenient for workers to push the concentrate recovery tank to move. Furthermore, by pulling the second connecting frame outward to separate the pin and roller from the locking groove, the third spring can drive the anti-slip pad to move downward automatically to fit against the ground and fix the concentrate recovery tank. Both the first and second connecting frames can be controlled by the worker's feet, eliminating the need for the worker to bend over, thus greatly improving the ease of use of the device.

[0015] The screw is screwed into the threaded hole of the support foot to fix the anti-slip pad to the bottom of the support foot. When the screw is tightened, the first spring will drive the round-headed pin to insert into the positioning hole. With the magnetic attraction of the magnet, the screw connection between the screw and the support foot can be improved, so that the anti-slip pad can be stably fixed to the bottom of the support foot. When the anti-slip pad needs to be replaced due to wear, simply rotate the anti-slip pad to separate the screw from the threaded hole of the support foot, and then the anti-slip pad and the screw can be removed and replaced.

[0016] By using rollers, the sliding friction between the support foot and the pin can be changed to rolling friction between the support foot and the rollers, thereby improving the ease with which the support foot moves upward. Attached Figure Description

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3 A reverse osmosis concentrate recovery and utilization device includes a concentrate recovery tank 1. A set of first connecting frames 13 are slidably arranged on both the left and right sides of the concentrate recovery tank 1. Support legs 15 and third springs 23 are evenly fixedly arranged at the bottom of the first connecting frames 13. Anti-slip pads 16 are placed on the bottom of the support legs 15. A second connecting frame 14 is placed on the outer side of the support legs 15. A pin 2 and a second spring 21 are evenly fixedly arranged on the side of the second connecting frame 14 near the support legs 15. An installation groove is opened on the side of the pin 2 near the support legs 15. A roller 22 is rotatably arranged in the installation groove via a rotating shaft. An arc-shaped positioning groove 24 and a locking groove 25 are opened on the outer side of the support legs 15. The roller 22 is located in the arc-shaped positioning groove 24. The pin 2 and the roller 22 are locked. Corresponding to the fixed groove 25, the bottom of the concentrate recovery tank 1 is uniformly fixed with casters 11. The casters 11 at the bottom of the anti-slip mat 16 are flush with each other. The rebound force of the third spring 23 causes the first connecting frame 13 to have a downward pulling force. This causes the support foot 15 to press down on the anti-slip mat 16 through the first connecting frame 13, thereby making the anti-slip mat 16 fit tightly against the ground. This uses friction to stably fix the concentrate recovery tank 1 on the ground. At the same time, the second spring 21 uses its own rebound force to drive the pin 2 to move inward through the second connecting frame 14, thereby causing the roller 22 to press into the arc-shaped positioning groove 24, thereby limiting the inward pressure on the support foot 15, thereby improving the stability of the support foot 15 and the anti-slip mat 16.

[0023] The arc-shaped positioning groove 24 is located above the locking groove 25. A set of support frames 12 are fixedly installed on both the left and right sides of the concentrate recovery tank 1. The first connecting frame 13 is located above the support frame 12. The third spring 23 is located on the outer ring of the support foot 15 and is fixedly installed between the first connecting frame 13 and the support frame 12. The second connecting frame 14 is located on the outside of the support frame 12. The second spring 21 is located on the outer ring of the pin 2 and is fixedly installed between the second connecting frame 14 and the support frame 12. A first through hole is evenly distributed through the top of the support frame 12, and a second through hole is distributed through the inner wall of the first through hole. The bottom of the support foot 15 is connected to the anti-slip pad 16 through the first through hole. The pin 2 and the roller 22 are inserted into the second through hole. Inside, when the concentrated water recovery tank 1 needs to be moved, the worker only needs to insert their toes into the first connecting frame 13 and pull the first connecting frame 13 upwards to move it. This raises the first connecting frame 13, causing the support foot 15 and the anti-slip pad 16 to move upwards. At this time, the support foot 15 will move downwards along the roller 22. The roller 22 changes the original sliding friction between the support foot 15 and the pin 2 to rolling friction between the support foot 15 and the roller 22, thereby improving the ease of upward movement of the support foot 15. When the support foot 15 moves upwards and aligns the locking groove 25 with the pin 2, the second spring 21 uses its own rebound force to drive the pin 2 and the second spring 21 to insert into the locking groove 25 through the second connecting frame 14. The height of the support foot 15 is fixed in this way, and the anti-slip mat 16 is separated from the ground. Then the concentrated water recovery tank 1 can be easily moved by the casters 11. A screw 161 is fixedly installed on the top of the anti-slip mat 16. A positioning hole is opened on the outer side of the screw 161. A threaded hole is opened on the bottom of the support foot 15. The screw 161 is screwed into the threaded hole. An installation hole is opened on the inner side wall of the threaded hole. A first spring 162 is fixedly installed in the installation hole. A round-headed pin 163 is fixedly installed on the outer side of the first spring 162. A magnetic block 164 is magnetically attracted to the round head of the round headed pin 163. The round head of the round headed pin 163 is inserted into the positioning hole, and the magnetic block 164 is magnetically attracted to the positioning hole. The screw 161 is then fixed in place. The anti-slip pad 16 is screwed into the threaded hole of the support foot 15, thereby fixing the anti-slip pad 16 to the bottom of the support foot 15. When the screw 161 is tightened, the first spring 162 will drive the round head pin 163 to insert into the positioning hole, thereby stabilizing the screw 161. At the same time, with the magnetic attraction of the magnetic block 164, the insertion stability of the round head pin 163 can be further improved, thereby further improving the screw connection stability between the screw 161 and the support foot 15, so that the anti-slip pad 16 can be stably fixed to the bottom of the support foot 15. When the anti-slip pad 16 needs to be replaced due to wear, simply rotate the anti-slip pad 16 to separate the screw 161 from the threaded hole of the support foot 15, and then the anti-slip pad 16 together with the screw 161 can be removed and replaced.

[0024] Working principle: The rebound force of the third spring 23 causes the first connecting frame 13 to have a downward pulling force. This causes the first connecting frame 13 to drive the support foot 15 to press down on the anti-slip pad 16, thereby making the anti-slip pad 16 fit tightly against the ground. This uses friction to stably fix the concentrated water recovery tank 1 on the ground. At the same time, the second spring 21 uses its own rebound force to drive the pin 2 to move inward through the second connecting frame 14, thereby causing the roller 22 to press tightly into the arc-shaped positioning groove 24. This applies inward limiting pressure to the support foot 15, thereby improving the stability of the support foot 15 and the anti-slip pad 16.

[0025] When the concentrated water recovery tank 1 needs to be moved, the worker only needs to insert their toes into the first connecting frame 13 and pull the first connecting frame 13 upwards to move it. This raises the first connecting frame 13, causing the support foot 15 and the anti-slip pad 16 to move upwards. At this time, the support foot 15 will move downwards along the roller 22. The roller 22 changes the original sliding friction between the support foot 15 and the pin 2 to rolling friction between the support foot 15 and the roller 22, thereby improving the ease of moving the support foot 15 upwards. When the support foot 15 moves upwards and aligns the locking groove 25 with the pin 2, the second spring 21 uses its own rebound force to drive the pin 2 and the second spring 21 to insert into the locking groove 25 through the second connecting frame 14, thereby fixing the height of the support foot 15. At this time, the anti-slip pad 16 separates from the ground, and then the concentrated water recovery tank 1 can be moved conveniently by the caster wheel 11.

[0026] Once the concentrated water recovery tank 1 is moved to the designated position, the worker only needs to insert their toes into the second connecting frame 14 and pull the second connecting frame 14 outward. At this time, the second connecting frame 14 pulls the pin 2 and roller 22 to separate from the locking groove 25. The third spring 23 uses its own rebound force to drive the support foot 15 and anti-slip pad 16 downward through the first connecting frame 13, thereby making the anti-slip pad 16 fit tightly with the ground. Then, when the foot is separated from the second connecting frame 14, the second spring 21 uses its own rebound force to drive the pin 2 and roller 22 inward through the second connecting frame 14, and drives the roller 22 to move into the arc-shaped positioning groove 24.

[0027] The screw 161 is screwed into the threaded hole of the support foot 15, thereby fixing the anti-slip pad 16 to the bottom of the support foot 15. When the screw 161 is tightened, the first spring 162 will drive the round-headed pin 163 to insert into the positioning hole, thereby stabilizing the screw 161. At the same time, with the magnetic attraction of the magnetic block 164, the insertion stability of the round-headed pin 163 can be further improved, thereby further improving the screw connection stability between the screw 161 and the support foot 15. Thus, the anti-slip pad 16 can be stably fixed to the bottom of the support foot 15. When the anti-slip pad 16 needs to be replaced due to wear, simply rotate the anti-slip pad 16 to separate the screw 161 from the threaded hole of the support foot 15, and then the anti-slip pad 16 together with the screw 161 can be removed and replaced.
