Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of thermal power plant sewage treatment, in particular to a thermal power plant sewage treatment device. BACKGROUND

[0002] As a high energy consumption power generation method, thermal power generation determines its water consumption and the huge amount of waste water generated. In order to save water resources, the plant realizes waste water classification, recycling and reduction of production water, and reduces cost. For example, the patent number CN109351032B discloses a thermal power plant sewage treatment and recycling technology, which can remove suspended solids and other impurities in sewage. However, the conveying distance of the conveyor belt is relatively long during the process of salvaging suspended solids from sewage. During the conveying process, the salvaged impurities contain a large amount of water, which will be scattered everywhere with the conveyor belt, making the working environment humid. At the same time, the sewage contains a large amount of harmful substances, which can easily scatter on the body of the workers, causing damage to the workers.

[0003] Therefore, the present application designs a thermal power plant sewage treatment device to solve the above problems. SUMMARY

[0005] To achieve the above purpose, the present application provides the following technical scheme: a thermal power plant sewage treatment device, comprising a treatment box, the inside of the treatment box is provided with two symmetrical decontamination plates about it, the two ends of each decontamination plate are fixedly connected with rotating shafts, the end close to the decontamination plate of the rotating shaft is rotatably connected with a sliding block, and sliding grooves for the up and down sliding of the sliding blocks are formed in the two sides of the treatment box; the middle part of the rotating shaft is fixedly connected with a first gear; a first rack for driving the first gear to rotate by ninety degrees is arranged on the side of the first gear, the first rack is fixedly connected on the side of the treatment box, driving mechanisms are arranged on the two sides of the decontamination plate, and a storage mechanism is arranged on the side of the treatment box.

[0006] As a further scheme of the present application, the driving mechanism comprises a connecting plate, the two ends of the connecting plate are rotatably connected with the end parts of the rotating shafts, connecting rods are fixedly connected on the two sides of the connecting plate, the upper end of each connecting rod is fixedly connected with a second rack, a second gear that can drive rotation is arranged above the second rack, a first winding roller is fixedly connected on the second gear, a first traction rope is wound around the first winding roller, a cleaning plate is fixedly connected at the end of the first traction rope away from the second gear, the cleaning plate is an extension plate, a first spring for resetting the cleaning plate is fixedly connected between the first winding roller and the cleaning plate; a discharge groove for discharging sundries is formed in the side of the treatment box.

[0007] A second traction rope is fixedly connected to the connecting plate, and a second take-up roller is fixedly connected to the upper end of the second traction rope. A first motor is fixedly connected to the shaft on the lower surface of the second take-up roller, and the first motor is fixedly connected to the processing box through a fixing plate.

[0008] As a further embodiment of the present invention, the storage mechanism includes a storage box, which is fixedly connected to the side of the processing box. A partition plate is movably installed in the upper middle part of the storage box, and the partition plate has a drainage hole.

[0009] As a further embodiment of the present invention, a baffle plate is provided below the discharge trough to block debris. During operation, the baffle plate can block the debris pushed out by the discharge trough from falling onto the structure on the side of the processing box, thus preventing the debris from affecting the rotation between the structures and improving work efficiency.

[0010] As a further embodiment of the present invention, a guide roller is provided at each corner of the second traction rope to ensure that the second traction rope is not excessively worn during operation and to improve the service life of the second traction rope.

[0013] As a further aspect of the present invention, the width of the shield is adapted to the width of the inner wall of the storage box.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The sludge removal plate first enters the sewage in a vertical position, and then becomes horizontal. This process allows suspended solids in the sewage to be scooped onto the sludge removal plate. As the sludge removal plate moves upward a certain distance, most of the water in the impurities can be drained out first. This draining process also occurs inside the treatment tank, preventing splashing onto the workers. Since the area of ​​the sludge removal plate is equal to the cross-sectional area of ​​the treatment tank, the sludge removal plate can more comprehensively and quickly remove impurities from the treatment tank, reducing the time required and improving work efficiency. Then, the cleaning plate can scrape off the impurities from the sludge removal plate, preventing them from adhering to the sludge removal plate and being reintroduced into the sewage in subsequent processes, thus affecting the subsequent treatment of impurities in the sewage and further improving the time required for sewage impurity treatment.

[0016] 2. When debris is pushed out through the discharge chute, it will not fall onto the gears or other structures on the side of the processing box due to the obstruction of the baffle plate. Instead, the debris will fall onto the partition plate, which separates the debris from the moisture in the debris. This allows the water to enter the bottom of the storage box, and the debris will gradually dry after being isolated by the partition plate. This facilitates subsequent processing by the staff and prevents wastewater from splashing when the staff is handling the water-containing debris. By preventing wastewater from falling onto the staff's clothes, the safety of the staff is ensured.

[0017] 3. The baffle plate can block the debris pushed out by the discharge trough from the cleaning plate and drop it onto the structure on the side of the processing box, preventing the debris from affecting the rotation between the structures and improving work efficiency.

Detailed Implementation

[0026] Please see Figures 1-6This invention provides a technical solution: a wastewater treatment device for a thermal power plant, comprising a treatment tank 1, wherein two symmetrically arranged cleaning plates 2 are arranged inside the treatment tank 1, and a rotating shaft 3 is fixedly connected to both ends of each cleaning plate 2. A sliding block 4 is rotatably connected to one end of the rotating shaft 3 near the cleaning plate 2. Sliding grooves 7 for the sliding blocks 4 to slide up and down are provided on both sides of the treatment tank 1. A first gear 5 is fixedly connected to the middle of the rotating shaft 3. A first rack 6 for driving the first gear 5 to rotate 90 degrees is arranged on the side of the first gear 5. The first rack 6 is fixedly connected to the side of the treatment tank 1. A driving mechanism is arranged on both sides of the cleaning plates 2, and a storage mechanism is arranged on the side of the treatment tank 1.

[0027] As a further embodiment of the present invention, the driving mechanism includes a connecting plate 22, both ends of which are rotatably connected to the ends of the rotating shaft 3. Connecting rods 8 are fixedly connected to both sides of the connecting plate 22. A second rack 9 is fixedly connected to the upper end of the connecting rod 8. A second gear 10 that can be driven to rotate is provided above the second rack 9. A first take-up roller 11 is fixedly connected to the second gear 10. A first traction rope 13 is wound around the first take-up roller 11. A cleaning plate 14 is fixedly connected to the end of the first traction rope 13 away from the second gear 10. The cleaning plate 14 is a telescopic plate. A first spring 12 for resetting the cleaning plate 14 is fixedly connected between the first take-up roller 11 and the cleaning plate 14. A discharge slot 15 for discharging debris is provided on the side of the processing box 1.

[0028] A second traction rope 16 is fixedly connected to the connecting plate 22. A second take-up roller 17 is fixedly connected to the upper end of the second traction rope 16. A first motor 18 is fixedly connected to the shaft on the lower surface of the second take-up roller 17. The first motor 18 is fixedly connected to the processing box 1 through the fixing plate 23.

[0029] During operation: The sewage is always kept in the lower position of the treatment tank 1 and on the lower surface of the cleaning plate 2. Then, the first motor 18 is started to rotate. The first motor 18 drives the second winding roller 17 to rotate, so that the second winding traction rope 16 is released. As the second traction rope 16 is released, the connecting plate 22 gradually moves down. At this time, the second rack 9 gradually moves below the second gear 10 and disengages from the second gear 10. Then, when the connecting plate 22 drives the cleaning plate 2 to move down to the bottom of the chute 7 through the rotating shaft 3, the first gear 5 meshes with the first rack 6. The first rack 6 drives the first gear 5 to rotate 90 degrees. At this time, the cleaning plate 2 changes from a horizontal state to a vertical state. At this time, the connecting plate 22 drives the sliding block 4 to move to the bottom of the chute 7 through the rotating shaft 3.

[0030] Then, the first motor 18 is driven to wind up the second traction rope 16, and the first gear 5 reverses the first rack 6. At this time, the cleaning plate 2 gradually changes from a vertical state to a horizontal state. The cleaning plate 2 then scoops up the debris on the sewage and onto itself. Then, the second traction rope 16 continues to wind up, and the cleaning plate 2 continues to move upward under the action of the sliding block 4. When the second rack 9 moves to mesh with the second gear 10, the continuously moving second rack 9, through meshing with the second gear 10, causes the first winding roller 11 to rotate continuously, winding up the first traction rope 13. Through the winding of the first traction rope 13, the cleaning plate 14 moves from left to right on the cleaning plate 2, gathering the debris on the cleaning plate 2 together, and then pushing it out through the discharge trough 15. The plate enters the sewage vertically and then becomes horizontal. This process allows suspended solids in the sewage to be collected onto the cleaning plate 2. As the cleaning plate 2 moves upward a certain distance, most of the water in the impurities can be drained out first. This draining also occurs within the treatment tank 1, preventing splashing onto the workers. Since the area of ​​the cleaning plate 2 is equal to the cross-sectional area of ​​the treatment tank 1, the cleaning plate 2 can collect the impurities in the treatment tank 1 more comprehensively, quickly, and in less time, improving work efficiency and saving time. Then, the cleaning plate 14 can scrape off the impurities on the cleaning plate 2, preventing them from adhering to the cleaning plate 2 and being reintroduced into the sewage in subsequent work, thus affecting the subsequent treatment of impurities in the sewage and further improving the time for treating impurities in the sewage.

[0031] As a further embodiment of the present invention, the storage mechanism includes a storage box 20, which is fixedly connected to the side of the processing box 1. A partition plate 21 is movably installed in the upper middle part of the storage box 20, and the partition plate 21 has a leakage hole.

[0032] During operation: When debris is pushed out through the discharge trough 15, it will not fall onto the gears or other structures on the side of the processing box 1 due to the obstruction of the baffle 19. Instead, the debris will fall onto the partition plate 21, which separates the debris from the water in it, allowing the water to enter the bottom of the storage box 20. After being isolated by the partition plate 21, the debris gradually dries, making it easier for staff to handle. This also prevents wastewater from splashing when staff are handling water-containing debris, ensuring staff safety by preventing wastewater from getting onto their clothes.

[0033] As a further embodiment of the present invention, a baffle plate 19 for blocking debris is provided below the discharge trough 15. During operation, the baffle plate 19 can block the debris pushed out by the discharge trough 15 by the cleaning plate 14 and drop it onto the structure on the side of the processing box 1, so as to avoid the debris affecting the rotation between the structures and improve work efficiency.

[0034] As a further embodiment of the present invention, a guide roller is provided at each corner of the second traction rope 16 to ensure that the second traction rope 16 is not excessively worn during operation and to improve the service life of the second traction rope.

[0035] As a further embodiment of the present invention, the partition 21 is capable of longitudinal height adjustment in the storage box 20.

[0036] As a further embodiment of the present invention, the second traction rope 16 located on both sides of the processing box 1 is fixed on the same side of the second take-up roller 17.

[0037] As a further embodiment of the present invention, the width of the shield 19 is adapted to the width of the inner wall of the storage box 20.

[0038] Working principle: The sewage is kept in the lower position of the treatment tank 1 and on the lower surface of the cleaning plate 2. Then, the first motor 18 is started to rotate. The first motor 18 drives the second winding roller 17 to rotate, so that the second winding traction rope 16 is released. As the second traction rope 16 is released, the connecting plate 22 gradually moves down. At this time, the second rack 9 gradually moves below the second gear 10 and disengages from the second gear 10. Then, when the connecting plate 22 drives the cleaning plate 2 to move down to the bottom of the chute 7 through the rotating shaft 3, the first gear 5 meshes with the first rack 6. The first rack 6 drives the first gear 5 to rotate 90 degrees. At this time, the cleaning plate 2 changes from a horizontal state to a vertical state. At this time, the connecting plate 22 drives the sliding block 4 to move to the bottom of the chute 7 through the rotating shaft 3.

[0039] Then, the first motor 18 is driven to wind up the second traction rope 16, and the first gear 5 reverses the first rack 6. At this time, the cleaning plate 2 gradually changes from a vertical state to a horizontal state. The cleaning plate 2 then scoops up the debris on the sewage and onto itself. Then, the second traction rope 16 continues to wind up, and the cleaning plate 2 continues to move upward under the action of the sliding block 4. When the second rack 9 moves to mesh with the second gear 10, the continuously moving second rack 9, through meshing with the second gear 10, causes the first winding roller 11 to rotate continuously, winding up the first traction rope 13. Through the winding of the first traction rope 13, the cleaning plate 14 moves from left to right on the cleaning plate 2, gathering the debris on the cleaning plate 2 together, and then pushing it out through the discharge trough 15. The plate enters the sewage vertically and then becomes horizontal. This process allows suspended solids in the sewage to be scooped onto the cleaning plate 2. As the cleaning plate 2 moves upward a certain distance, it can drain most of the water from the impurities. The draining process also occurs within the treatment tank 1, preventing splashing onto the workers. Since the area of ​​the cleaning plate 2 is equal to the cross-sectional area of ​​the treatment tank 1, the cleaning plate 2 can more comprehensively and quickly scoop up the impurities in the treatment tank 1, reducing the time required and improving work efficiency. Then, the cleaning plate 14 can scrape off the impurities from the cleaning plate 2, preventing them from adhering to the cleaning plate 2 and being reintroduced into the sewage in subsequent work, thus affecting the subsequent treatment of impurities in the sewage and further improving the time required for treating impurities in the sewage.

[0040] When debris is pushed out through the discharge trough 15, it will not fall onto the gears or other structures on the side of the processing box 1 due to the obstruction of the baffle 19. Instead, the debris will fall onto the partition plate 21, which separates the debris from the water in it, allowing the water to enter the bottom of the storage box 20. After being isolated by the partition plate 21, the debris gradually dries, making it easier for staff to handle it. This also prevents wastewater from splashing when staff are handling water-containing debris and ensures staff safety by preventing wastewater from getting onto their clothes.
