Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and in particular to a device for treating electrochemical hydrogen production wastewater. Background Art

[0002] The electrochemical hydrogen production wastewater treatment device combines the two processes of hydrogen production and wastewater treatment. While treating wastewater, it can produce valuable hydrogen, thus realizing the recycling of resources.

[0003] For example, some industrial wastewater treatment plants use this method to not only reduce the cost of wastewater treatment, but also obtain certain economic benefits by selling hydrogen. Compared with traditional wastewater treatment methods (such as biological treatment, chemical precipitation, etc.), electrochemical hydrogen production wastewater treatment can be carried out under relatively mild conditions (normal temperature and normal pressure), and the reaction speed is fast. It can effectively treat high-concentration, difficult-to-degrade organic wastewater. At the same time, by reasonably controlling the electrolysis conditions (such as current density, voltage, etc.), the efficiency of wastewater treatment and the output of hydrogen can be further improved.

[0004] In the prior art, the wastewater electrolysis hydrogen production device disclosed in CN117926278A performs membrane filtration and concentration treatment on wastewater through a wastewater membrane filtration and concentration device to obtain clean water and concentrated water respectively, and then purifies the concentrated water and electrolyzes it to produce hydrogen. Since the processing volume of concentrated water is greatly reduced, the operating cost and floor space of the wastewater electrolysis hydrogen production device can be reduced. Since the wastewater electrolysis hydrogen production device has strong adaptability to saline wastewater, the desalination efficiency of the concentrated water can be ensured. The above-mentioned wastewater treatment and hydrogen production system is particularly suitable for low-salt wastewater.

[0005] However, there are still some defects in the actual treatment process. During the electrochemical hydrogen production wastewater treatment process, in order to adjust the pH value of the wastewater and optimize the electrochemical reaction conditions, the pH value will be adjusted to the acidic or alkaline range to improve the electrolysis efficiency or the removal effect of specific pollutants. Therefore, certain pH regulators will be added during the treatment process, such as sulfuric acid, hydrochloric acid (for lowering the pH value) or lime, sodium hydroxide (for raising the pH value). However, when adding the pH regulator, the existing device needs to manually add the barreled pH into the reagent box, which is not only time-consuming and labor-intensive, but also requires workers to be on duty for a long time.

DETAILED DESCRIPTION

[0029] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] like Figures 1-9The electrochemical hydrogen production wastewater treatment device shown in the figure includes a wastewater hydrogen production pool 1 and a dosing mechanism 2. The dosing mechanism 2 is mainly composed of a mixing cylinder, a stirring structure and a water pump, etc., which can automatically mix the reagents and add them to the wastewater hydrogen production pool 1 in a quantitative manner. The dosing mechanism 2 is connected to the wastewater hydrogen production pool 1 through a pipeline. The front side of the dosing mechanism 2 is provided with a placement plate 3 fixed on the ground for placing a tray, a fixing frame 4 is provided above the placement plate 3, and the fixing frame 4 is fixedly connected to the ground on both sides of the placement plate 3. The bottom end of the fixing frame 4 is slidably connected to a fixing frame 5, and the placement plate 3 is fixedly connected to a movable guide rail 6, which is provided with a mechanism for automatically opening the bottle cap of the reagent barrel. The bottle opening mechanism 7 is mainly composed of components such as a motor, a telescopic cylinder and an air suction structure. It can automatically move on the movable guide rail 6 to open multiple medicine barrels. It is a mature technology in the existing technology and will not be described in detail here. The side wall of the fixed frame 5 is fixedly connected to an L-shaped plate 8, and the inner side of the fixed frame 5 is slidably connected to an L-shaped block 9. The inner side of the fixed frame 5 is provided with a driving mechanism for driving the L-shaped block 9 to move back and forth. The fixed frame 4 is provided with a flipping mechanism for flipping the medicine barrel. The side wall of the L-shaped block 9 is provided with a straight groove 10, and the inner side of the straight groove 10 is slidably connected to a loading block 11. The loading block 11 is provided with a hooking barrel mechanism for hooking the handle of the medicine barrel;

[0032] The side wall of the L-shaped plate 8 is provided with a horizontal groove 12, and the bottom of the horizontal groove 12 away from the dosing mechanism 2 is provided with a vertical groove 13, and a horizontal V-shaped groove 14 is provided on the bottom side of the vertical groove 13. An inclined groove 15 is provided between the top of the V-shaped groove 14 and the top of the horizontal groove 12. A circular hole is provided on the side wall of the loading block 11, and a round rod 16 is slidably connected to the inside of the circular hole, and one end of the round rod 16 is inserted into the inner side of the V-shaped groove 14, and an upper spring 18 is fixedly connected between the other end of the round rod 16 and the inner side of the circular hole. A return spring 17 is fixedly connected between the top of the straight groove 10 and the top of the loading block 11. An inward groove 19 is provided at the corner of the V-shaped groove 14, and the connection between the top of the groove 19 and the V-shaped groove 14 is inclined. Through the setting of the groove 19, the corner of the V-shaped groove 14 and the inclined groove at the bottom can be made to have a step, thereby limiting the round rod 16 from sliding downward and moving according to the specified path;

[0033] The hook barrel mechanism includes a quarter-circular ring-shaped hook ring 20, and a ring frame 21 is fixedly connected to the side wall of the loading block 11. The hook ring 20 is rotatably connected to the inner side of the ring frame 21, and the end of the hook ring 20 passes through the side wall of the loading block 11. An arc spring 22 is fixedly connected between the top of the hook ring 20 and the top inside the ring frame 21. The arc spring 22 facilitates the rapid pulling of the hook ring 20 for reset. At the same time, the material selection and structural design of the hook ring 10 fully consider its bearing capacity to ensure that it can withstand the weight of the medicine barrel in the pulled-out state. The setting of the arc spring 22 further enhances the reset ability and stability of the hook ring 20. A top groove is provided at the top of the loading block 11, and an electric telescopic cylinder 23 is fixedly connected to the bottom end of the top groove. A pulling groove is provided at the bottom end of the top groove. The top inner side of the hook ring 20 is fixedly connected A pull rope 24 is connected, and a guide roller 25 is rotatably connected to the inner side of the pull groove. The guide roller 25 guides the sliding of the pull rope 24 and avoids friction between the pull rope 24 and the corner of the pull groove, which affects the service life of the pull rope 24. The other end of the pull rope 24 passes under the guide roller 25 and is fixedly connected to the output end of the electric telescopic cylinder 23. A quarter-circular ring-shaped limiting ring 26 is fixedly connected to the side wall of the loading block 11. The limiting ring 26 can seal the medicine barrel handle between the hook ring 20, the loading block 11 and the limiting ring 26 after the hook ring 20 is pulled out, so as to avoid the medicine barrel from falling off when it is turned over. The design of the limiting ring 26 ensures that the medicine barrel always remains stable during the hooking process. Even if the supporting effect of the hook ring 20 is limited, the limiting ring 26 can provide additional fixation and support.

[0034] The drive mechanism includes a drive motor 27, an upper screw 28 is rotatably connected to the inner side of the fixed frame 5, the drive motor 27 is fixedly connected to the front side of the fixed frame 5, the output end of the drive motor 27 passes through the inner side of the fixed frame 5 and is fixedly connected to the side wall of the upper screw 28, and an upper threaded hole is opened on the side wall of the L-shaped block 9, and the upper screw 28 is threadedly connected to the upper threaded hole;

[0035] The flip mechanism includes an L-shaped flip plate 29, a flip motor 30 is fixedly connected to the side wall of the fixing frame 4, the output end of the flip motor 30 passes through the fixing frame 4 and is fixedly connected to the flip plate 31, and the L-shaped flip plate 29 is fixedly connected to the side wall of the flip plate 31;

[0036] In the process of adding reagents to the wastewater treatment hydrogen production, first, the reagent fork on the pallet is placed on the placement plate 3 by a forklift (if the reagent barrels on the pallet are not neat at this time, the driver needs to use the forklift's cargo fork to squeeze the reagent barrels on the limit plate 32 and the side wall of the rear plate 34 to ensure that the reagent barrels on the pallet are neatly placed, thereby ensuring the normal operation of the subsequent drug pouring work), and then the bottle opening mechanism 7 can be controlled to unscrew the bottle cap of the reagent barrel (the unscrewed bottle cap can be sucked by the bottle opening mechanism 7, and then moved on the moving guide rail 6 by the bottle opening mechanism 7, transferred to the side of the placement plate 3 and discarded, and then transferred to the top of the next reagent bottle), and then the drive motor 27 is controlled to start and drive the upper screw 28 to rotate, thereby driving the screw The L-shaped block 9 connected with the groove moves, and at the same time drives the loading block 11 to move, and drives the round rod 16 to move in the horizontal groove 12 (the round rod 16 in the initial position needs to be located in the horizontal groove 12 to avoid affecting the normal fork placement of the tray and hindering the normal operation of the bottle opening mechanism 7). Then, when the loading block 11 moves to the top of the handle of the medicine barrel where the medicine needs to be poured, the drive motor 27 needs to be controlled to stop running, and the round rod 16 will move to the corner of the horizontal groove 12 and the vertical groove 13, thereby releasing the limit on the round rod 16. Subsequently, the loading block 11 is pushed downward under the elastic force of the return spring 17, and the round rod 16 is driven to slide in the vertical groove 13, and at the same time, the hook ring 20 is driven to move to the handle of the medicine barrel;

[0037] The electric telescopic cylinder 23 is then controlled to start the retraction output end, thereby pulling the pull rope 24 to move upward, and the pull rope 24 will drive the hook ring 20 to rotate inside the ring frame 21, and then it will be rotated out from the other side of the loading block 11 and pass through the handle of the medicine barrel, while gradually stretching the arc spring 22. Subsequently, the screwed-out end of the hook ring 20 moves below the limit ring 26, thereby completing the hooking of the handle. Subsequently, the driving motor 27 can be controlled to operate, driving the loading block 11 to move forward, while driving the round rod 16 to slide into the V-shaped groove 14, and then the round rod 16 is squeezed by the inclined surface of the V-shaped groove 14 and gradually moves upward, and drives the loading block 11 to slide inside the straight groove 10, while gradually compressing the return spring 17, and the hook ring 20 will hook the medicine barrel forward, away from the moving guide rail 6, and then the round rod 16 moves to the corner of the V-shaped groove 14 and is located next to the groove 19, so that under the elastic force of the upper spring 18, the side end of the upper round rod 16 is pushed into the groove 19;

[0038] The cam 20 is pressed against the inner wall of the V-shaped groove 14 so that the loading block 11 can move upwards, and the round rod 16 can only slide upwards gradually because of the restriction of the step between the groove 19 and the inclined groove below the V-shaped groove 14, thereby driving the loading block 11 to continue to move upwards. At the same time, the hook ring 20 drives the medicine barrel to move backwards and upwards, and then the round rod 16 moves out of the V-shaped groove 14, slides through the inclined groove 15 and into the transverse groove 12 (at this time, the medicine barrel will pass over the moving guide rail 6), and finally the hook ring 20 hooks the medicine barrel to the L-shaped flap 29 (it should be noted here that as long as the cross section of the hook ring 20 is wide enough and the inner side of the handle is flat, the medicine barrel will not shake back and forth when it is hooked up, and will accurately fall on the L-shaped flap 29);

[0039] Then the flip motor 30 can be controlled to start and drive the flip plate 31 and the L-shaped flip plate 29 to rotate, thereby dragging the bottom of the medicine barrel to flip upward. At this time, the handle of the medicine barrel will flip on the hook ring 20, thereby pouring the pH adjuster in the medicine barrel into the mixing cylinder of the dosing mechanism 2 (it should be noted here that due to the limitation of the hook ring 20, the flip mechanism cannot completely flip the medicine barrel 90 degrees, but the inner side wall of the medicine barrel is tilted toward the bottle mouth, so the medicine in the barrel can be completely poured out without flipping 90 degrees). After the pouring is completed, the flip motor 30 is controlled to reverse and drive the medicine barrel to reset. Then the drive motor 27 is controlled to rotate forward to drive the loading block 11 to reset and put the empty medicine barrel back on the tray. Then the electric telescopic cylinder 23 is controlled to extend back, the hook ring 20 is retracted, and then the loading block 11 is removed (the round rod 16 needs to be driven through the V-groove 14 and the inclined groove 15 to move into the horizontal groove 12).

[0040] In order to be able to hook up the medicine barrels on the tray in sequence for pouring the medicine, a through slot is provided at the top of the fixing frame 4. A T-shaped block 37 is fixedly connected to the top of the fixing frame 5 relative to the inner position of the through slot. A lower screw 38 is rotatably connected to the inner side of the through slot. A lower threaded groove is provided on the side wall of the T-shaped block 37. The lower screw 38 is threadedly connected to the lower threaded groove. A displacement motor 33 is fixedly connected to the side wall of the fixing frame 4. The output end of the displacement motor 33 passes through the inner side of the through slot and is fixedly connected to the side wall of the lower screw 38.

[0041] When the first medicine barrel is emptied and the loading block 11 is reset, the displacement motor 33 can be controlled to start and drive the lower screw 38 to rotate, thereby driving the threaded T-block 37 to move inside the through groove, and at the same time driving the fixed frame 5 to move above another medicine barrel, and driving the loading block 11 to move above the handle, then the drive motor 27 can be controlled to rotate forward to drive the hook ring 20 to move to the side of the handle, and then the electric telescopic cylinder 23 can be controlled to start to hook up the handle, and then the drive motor 27 can be started to hook up the medicine barrel. When the medicine barrel is completely hooked up, the displacement motor 33 can be controlled to reverse and drive the fixed frame 5 to reset. This can be repeated to hook up the medicine barrels in the front row of the tray in turn for pouring medicine.

[0042] The rear side of the lower block 35 is fixedly connected to the rear side of the lower block 35, and the output ends of the cylinders 36 are fixedly connected to the front side of the lower block 35 and the rear side of the rear plate 34.

[0043] When the front row of medicine barrels on the pallet are emptied, the cylinder 36 can be controlled to start and drive the rear plate 34 to move, thereby pushing the pallet forward and moving the rear row of medicine barrels to the loading position (it should be noted here that when the second row of medicine barrels are loaded, the empty barrels in the front row will be pushed to move, but they will not fall off the pallet. Therefore, before the forklift driver changes the pallet, he needs to use the fork to push the front row of empty barrels backward and place them completely on the pallet before he can change it).

[0044] The above shows and describes the basic principles, main features and advantages of the present invention, and it should be noted that the drive motor 27, the electric telescopic cylinder 23, the air cylinder 36, the flip motor 30 and the displacement motor 33 are all electrically connected to the PLC controller, and all the above-mentioned strokes can be automatically controlled by the automated program setting for loading.

[0045] Those skilled in the art should understand that the present invention is not limited to the above-mentioned embodiments. The above-mentioned embodiments and the specification only describe the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. These changes and improvements all fall within the scope of the present invention to be protected.
