Description

Technical Field

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

[0002] The electrochemical hydrogen production wastewater treatment device combines the two processes of hydrogen production and wastewater treatment. While treating wastewater, valuable hydrogen gas can be produced, realizing the recycling of resources. For example, some industrial wastewater treatment plants use this method, which can not only reduce the cost of wastewater treatment, but also obtain certain economic benefits by selling hydrogen gas. 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 (room temperature, atmospheric pressure), and the reaction speed is fast, which can effectively treat high-concentration and refractory 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 yield of hydrogen gas can be further improved.

[0003] In the prior art, the hydrogen production device by electrolyzing wastewater with the publication number of CN117926278A filters and concentrates the wastewater through a wastewater membrane filtration and concentration device to obtain clear water and concentrated water respectively, and then purifies and electrolyzes the concentrated water through the hydrogen production device by electrolyzing wastewater. Since the treatment amount of the concentrated water is greatly reduced, the operating cost and floor area of the hydrogen production device by electrolyzing wastewater can be reduced. Since the hydrogen production device by electrolyzing wastewater has strong adaptability to saline wastewater, the desalination efficiency of the concentrated water can be ensured. The above wastewater treatment and hydrogen production system is particularly suitable for low-salt wastewater.

[0004] However, there are still some defects in the actual treatment process. Since the device adjusts the pH value of the wastewater to optimize the electrochemical reaction conditions during the electrochemical hydrogen production wastewater treatment process, 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, a certain pH regulator will be added during the treatment process, such as sulfuric acid, hydrochloric acid (for reducing the pH value) or lime, sodium hydroxide (for increasing the pH value). However, when adding the pH regulator in the existing device, it is necessary to manually add the barreled pH into the reagent tank, which is not only time-consuming and laborious, but also requires workers to be on duty nearby for a long time.

[0005] Therefore, an electrochemical hydrogen production wastewater treatment device is proposed to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to propose an electrochemical hydrogen production wastewater treatment device to solve the disadvantages existing in the background art.

[0010] In the above technical solution, further, a guide roller is rotatably connected to the inside of the pulling groove. The other end of the pulling rope passes under the guide roller and is fixedly connected to the output end of the electric telescopic cylinder. A quarter-circular limiting ring is fixedly connected to the side wall of the feeding block.

[0011] In the above technical solution, further, the driving mechanism includes a driving motor. An upper screw rod is rotatably connected to the inside of the fixing frame. The driving motor is fixedly connected to the front side of the fixing frame, and the output end of the driving motor passes through the inside of the fixing frame and is fixedly connected to the side wall of the upper screw rod. An upper threaded hole is formed on the side wall of the L-shaped block, and the upper screw rod is threadedly connected to the upper threaded hole.

[0012] In the above technical solution, further, the flipping mechanism includes an L-shaped flap. A flipping motor is fixedly connected to the side wall of the fixed frame.

Through the arrangement of structures such as the air cylinder, the displacement motor and the lower screw rod, the present invention can automatically change the position of the hook barrel mechanism on the tray, thereby changing the hooking position, and can transfer the medicine barrels on the tray one by one for pouring medicine. At the same time, when the medicine barrels in the front row on the tray are emptied, the tray can be pushed forward through the cooperation of the air cylinder and the rear plate to change the position of the medicine barrel below the hook barrel mechanism, so that all the medicine barrels on the tray can be hooked for pouring medicine. Only the tray needs to be replaced by a forklift, without manual handling, further improving the convenience performance of the device. Description of the Drawings

Detailed implementation manners

[0019] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0020] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed below.

[0021] Such as Figures 1-9An electrochemical hydrogen production wastewater treatment device shown in the figure includes a wastewater hydrogen production pool 1 and a chemical dosing mechanism 2. The chemical dosing mechanism 2 is mainly composed of a chemical mixing cylinder, a stirring structure, a water pump and other structures, which can automatically mix chemicals and quantitatively add them into the wastewater hydrogen production pool 1. The chemical dosing mechanism 2 is connected to the wastewater hydrogen production pool 1 through a pipeline. There is a placement plate 3 fixed on the ground in front of the chemical dosing mechanism 2 for placing trays. Above the placement plate 3, there is a fixed frame 4, and the fixed frame 4 is fixedly connected to the ground on both sides of the placement plate 3. The bottom end of the fixed frame 4 is slidably connected with a fixed frame 5. A moving guide rail 6 is fixedly connected to the placement plate 3. On the moving guide rail 6, there is a bottle opening mechanism 7 for automatically opening the caps of chemical reagent barrels. The bottle opening mechanism 7 is mainly composed of components such as a motor, a telescopic cylinder and a suction structure, which can automatically move on the moving guide rail 6 to open the caps of multiple chemical reagent barrels. This 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 with an L-shaped plate 8. The inner side of the fixed frame 5 is slidably connected with an L-shaped block 9. Inside the fixed frame 5, there is a driving mechanism for driving the L-shaped block 9 to move back and forth. On the fixed frame 4, there is a flipping mechanism for flipping the chemical reagent barrels. A straight groove 10 is opened on the side wall of the L-shaped block 9. Inside the straight groove 10, a feeding block 11 is slidably connected. On the feeding block 11, there is a barrel hooking mechanism for hooking the handle of the chemical reagent barrel; A horizontal groove 12 is opened on the side wall of the L-shaped plate 8. At the bottom of the side of the horizontal groove 12 away from the chemical dosing mechanism 2, a vertical groove 13 is opened. At the bottom side of the vertical groove 13, a horizontal V-shaped groove 14 is opened. An inclined groove 15 is opened between the top end of the V-shaped groove 14 and the top of the horizontal groove 12. A round hole is opened on the side wall of the feeding block 11. Inside the round hole, a round rod 16 is slidably connected. One end of the round rod 16 is inserted into the inside of the V-shaped groove 14. A top spring 18 is fixedly connected between the other end of the round rod 16 and the inside of the round hole. A return spring 17 is fixedly connected between the top end of the straight groove 10 and the top of the feeding block 11. A recessed groove 19 is opened at the corner of the V-shaped groove 14. The connection between the top end of the recessed groove 19 and the V-shaped groove 14 is inclined. Through the setting of the recessed groove 19, a step can be formed between the corner of the V-shaped groove 14 and the inclined groove at the bottom, thereby restricting the downward sliding of the round rod 16 and making it move along a specified path; The bucket-hooking mechanism includes a quarter-circular hook ring 20. A circular ring frame 21 is fixedly connected to the side wall of the feeding block 11. The hook ring 20 is rotatably connected to the inner side of the circular ring frame 21, and the end of the hook ring 20 penetrates through the side wall of the feeding block 11. An arc-shaped spring 22 is fixedly connected between the top end of the hook ring 20 and the inner top end of the circular ring frame 21. The arc-shaped spring 22 facilitates the quick 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 bear the weight of the medicine bucket in the pulled-out state. The setting of the arc-shaped spring 22 further enhances the reset ability and stability of the hook ring 20. A top groove is opened at the top end of the feeding block 11. An electric telescopic cylinder 23 is fixedly connected to the bottom end of the top groove. A pulling groove is opened at the bottom end of the top groove. A pulling rope 24 is fixedly connected to the inner top end of the hook ring 20. A guide roller 25 is rotatably connected to the inner side of the pulling groove. The guide roller 25 plays a guiding role in the sliding of the pulling rope 24 and avoids the friction between the pulling rope 24 and the corner of the pulling groove, which affects the service life of the pulling rope 24. The other end of the pulling 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 limiting ring 26 is fixedly connected to the side wall of the feeding block 11. Through the limiting ring 26, after the hook ring 20 is pulled out, the handle of the medicine bucket can be sealed between the hook ring 20, the feeding block 11 and the limiting ring 26 to prevent the medicine bucket from falling off when it is flipped. And through the design of the limiting ring 26, it is ensured that the medicine bucket 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; The driving mechanism includes a driving motor 27. An upper screw rod 28 is rotatably connected to the inner side of the fixed frame 5. The driving motor 27 is fixedly connected to the front side of the fixed frame 5. The output end of the driving motor 27 passes through the inner side of the fixed frame 5 and is fixedly connected to the side wall of the upper screw rod 28. An upper threaded hole is opened on the side wall of the L-shaped block 9. The upper screw rod 28 is threadedly connected with the upper threaded hole; The flipping mechanism includes an L-shaped flipping plate 29. A flipping motor 30 is fixedly connected to the side wall of the fixed frame 4. The output end of the flipping motor 30 passes through the fixed frame 4 and is fixedly connected to the flipping plate 31. The L-shaped flipping plate 29 is fixedly connected to the side wall of the flipping plate 31; During the process of adding agents to hydrogen production from wastewater treatment, first, the forklift is used to fork the agents on the pallet onto the placement plate 3. (At this time, if the agent barrels on the pallet are not neatly arranged, the driver needs to use the forklift forks to squeeze the agent barrels against the side walls of the limit plate 32 and the rear plate 34 to ensure that the agent barrels on the pallet are neatly arranged, thus ensuring the normal operation of the subsequent medicine pouring work.) Subsequently, the bottle opening mechanism 7 can be controlled to unscrew the bottle cap of the agent barrel. (The unscrewed bottle cap can be sucked by the bottle opening mechanism 7, and then moved by the bottle opening mechanism 7 on the moving guide rail 6 and discarded beside the placement plate 3. After discarding, it can be moved above the next agent bottle.) Then, control the driving motor 27 to start and drive the upper screw rod 28 to rotate, which will drive the L-shaped block 9 connected by threads to move, drive the feeding block 11 to move, and drive the round rod 16 to move in the horizontal groove 12. (The round rod 16 at the initial position needs to be located in the horizontal groove 12 to avoid affecting the normal forking of the pallet and hindering the normal operation of the bottle opening mechanism 7.) Subsequently, when the feeding block 11 moves above the handle of the agent barrel that needs to pour medicine, at this time, control the driving motor 27 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. Then, under the elastic force of the return spring 17, the feeding block 11 is pushed downward to move, drive the round rod 16 to slide in the vertical groove 13, and drive the hook ring 20 to move beside the handle of the agent barrel; Then, control the electric telescopic cylinder 23 to start and retract the output end, thereby pulling the pull rope 24 upward. Subsequently, the pull rope 24 will drive the hook ring 20 to rotate inside the circular ring frame 21, and then unscrew from the other side of the feeding block 11 and pass through the handle of the agent barrel. At the same time, the arc spring 22 is gradually stretched. Subsequently, the screwed end of the hook ring 20 moves below the limit ring 26, thus hooking the handle. Then, continue to control the driving motor 27 to run, drive the feeding block 11 to move forward, drive the round rod 16 to slide into the V-shaped groove 14 at the same time, and then gradually push the round rod 16 upward by the inclined surface of the V-shaped groove 14, drive the feeding block 11 to slide inside the straight groove 10, gradually compress the return spring 17 at the same time, and the hook ring 20 will hook the agent barrel forward, away from the moving guide rail 6. Subsequently, the round rod 16 moves to the corner of the V-shaped groove 14 and is located beside the groove 19, so that the side end of the upper round rod 16 is pushed into the groove 19 under the elastic force of the upper spring 18; However, due to the limitation of the step between the groove 19 and the inclined groove below the V-shaped groove 14, it cannot move downward. At this time, the driving motor 27 can be controlled to reverse, driving the L-shaped block 9 and the feeding block 11 to move backward. At the same time, since the round rod 16 is inserted into the groove 19 and restricted, under the extrusion of the inner wall of the V-shaped groove 14, the round rod 16 can only gradually slide upward, driving the feeding block 11 to continue moving upward. At the same time, the hook ring 20 drives the medicine bucket to move backward and upward. Then, the round rod 16 moves out of the V-shaped groove 14 and slides into the horizontal groove 12 through the inclined groove 15 (at this time, the medicine bucket will pass above the moving guide rail 6). Finally, the hook ring 20 hooks the medicine bucket onto 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, when the medicine bucket is hooked, the medicine bucket will not shake back and forth, and thus will accurately fall on the L-shaped flap 29); Subsequently, the flipping motor 30 can be controlled to start, driving the flipping plate 31 and the L-shaped flap 29 to rotate, thereby dragging the bottom of the medicine bucket upward to flip. At this time, the handle of the medicine bucket will flip on the hook ring 20, so as to pour the pH regulator in the medicine bucket into the mixing cylinder of the medicine adding mechanism 2 (it should be noted here that due to the restriction of the hook ring 20, the flipping mechanism cannot completely flip the medicine bucket by 90 degrees. However, the inner side wall of the medicine bucket is inclined towards the bottle mouth, so the medicine in the bucket can be completely poured out without flipping the medicine bucket by 90 degrees). After the pouring is completed, control the flipping motor 30 to reverse to drive the medicine bucket to reset. Subsequently, control the driving motor 27 to rotate forward to drive the feeding block 11 to reset and put the empty medicine bucket back on the tray. Then, control the electric telescopic cylinder 23 to retract, retract the hook ring 20, and then take away the feeding block 11 (it is necessary to drive the round rod 16 to move into the horizontal groove 12 through the V-shaped groove 14 and the inclined groove 15).

[0022] In order to hook the medicine buckets on the tray one by one for pouring medicine, a through groove is opened at the top of the fixed frame 4. A T-shaped block 37 is fixedly connected to the top of the fixed frame 5 at a position corresponding to the inside of the through groove. A lower screw rod 38 is rotatably connected to the inside of the through groove. A lower thread groove is opened on the side wall of the T-shaped block 37, and the lower screw rod 38 is threadedly connected to the lower thread groove. A displacement motor 33 is fixedly connected to the side wall of the fixed frame 4, and the output end of the displacement motor 33 passes through the inside of the through groove and is fixedly connected to the side wall of the lower screw rod 38; After the first reagent barrel is emptied and the feeding block 11 resets, the displacement motor 33 can be controlled to start and drive the lower screw rod 38 to rotate, thereby driving the T-shaped block 37 connected by threads to move inside the through groove. At the same time, the fixed frame 5 is driven to move above another reagent barrel, and the feeding block 11 is driven to move above the handle. First, the driving motor 27 can be controlled to rotate forward to drive the hook ring 20 to move beside the handle, and then the electric telescopic cylinder 23 can be controlled to start to hook up the handle. Subsequently, the driving motor 27 is started to hook up the reagent barrel. When the reagent barrel is completely hooked up, the displacement motor 33 can be controlled to reverse to drive the fixed frame 5 to reset. Repeating this way, the reagent barrels in the front row of the tray can be hooked up in turn for pouring medicine.

[0023] To improve the stability during the operation of the device, a pair of limiting plates 32 for restricting the position of the tray are fixedly connected to the side wall of the placing plate 3. A rear plate 34 is provided at the rear side of the top end of the placing plate 3. Through the settings of the limiting plates 32 and the rear plate 34, the side and rear positions of the reagent barrels on the tray can be limited. And when the reagent barrels on the tray are not neatly arranged, the driver can use the forklift forks to squeeze the reagent barrels beside the limiting plates 32 and the rear plate 34, thereby ensuring that the reagent barrels on the tray are neatly arranged, so as to ensure that the subsequent hook ring 20 can hook the handle of the reagent barrel. An L-shaped lower block 35 is fixedly connected to the rear side of the placing plate 3. The rear plate 34 is arranged inside the lower block 35. A pair of cylinders 36 are fixedly connected to the rear side of the lower block 35. The output ends of the cylinders 36 all pass through the front side of the lower block 35 and are fixedly connected to the rear side of the rear plate 34. After the reagent barrels in the front row on the tray are emptied, the cylinders 36 can be controlled to start and drive the rear plate 34 to move, thereby pushing the tray forward to move the rear row of reagent barrels to the feeding position (it should be noted here that when feeding the second row of reagent barrels, the empty barrels that have been emptied in the front will be pushed to move, but will not fall off the tray. Therefore, before the forklift driver replaces the tray, the front row of empty barrels needs to be pushed backward by the forklift forks and completely placed on the tray before it can be replaced).

[0024] The above shows and describes the basic principle, main features and advantages of the present invention. And it should be noted here that the driving motor 27, the electric telescopic cylinder 23, the cylinder 36, the flipping motor 30 and the displacement motor 33 are all electrically connected to the PLC controller, and all the above-mentioned processes can be automatically controlled for feeding through an automated program setting.

[0025] Those skilled in the art of this industry should understand that the present invention is not limited by the above-mentioned embodiments. What is described in the above-mentioned embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
