Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a deep denitrification wastewater treatment device. Background Technology
[0002] Wastewater treatment equipment is a purification system used to treat urban sewage. It primarily uses physical, chemical, or biological purification methods to remove harmful substances from the wastewater. Chemical precipitation, in particular, involves adding chemical agents to the wastewater, causing a chemical reaction between the agents and dissolved substances in the wastewater to form insoluble compounds. These insoluble compounds are then removed through solid-liquid separation, thus purifying the wastewater. In treating nitrogen-containing wastewater, commonly used chemical precipitation methods include reactions that produce magnesium ammonium phosphate precipitates.
[0003] In the prior art, when using chemical agents to denitrify wastewater, insoluble compound precipitates may be generated. These precipitates will adhere to the inside of the treatment tank. If they are not removed in time, they may deposit on the inner wall of the treatment tank. Since the wastewater treatment time is long, it is usually not convenient to clean the attached precipitates. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, this utility model proposes a deep denitrification wastewater treatment device.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a deep denitrification wastewater treatment device, comprising a treatment tank, an L-shaped plate fixedly connected to the top of the treatment tank, a motor fixedly connected to one side of the L-shaped plate, a rotating rod fixedly connected to the output end of the motor, a stirring rod fixedly connected to the bottom of the rotating rod, a first bevel gear fixedly connected to the outer wall of the rotating rod, a second bevel gear meshing with one side of the first bevel gear, a fixing rod fixedly connected to one side of the L-shaped plate, a collar fixedly connected to one side of the fixing rod, a round rod rotatably connected to the inner wall of the collar, the round rod fixedly connected to one side of the second bevel gear, a round plate fixedly connected to the other end of the round rod, a sliding rod fixedly connected to one end of the round plate, a sliding frame slidably connected to the outer wall of the sliding rod, a vertical plate fixedly connected to the bottom of the sliding frame, a cleaning plate fixedly connected to the bottom of the vertical plate, the cleaning plate being disposed on the inner wall of the treatment tank, a wastewater pipe fixedly connected to one side of the treatment tank, and a valve fixedly connected to the outer wall of the wastewater pipe.
[0006] Furthermore, the treatment tank has an internal interlayer, an inlet pipe is installed at the top of one side of the treatment tank, and a drain pipe is fixedly connected to the bottom of the other side of the treatment tank. Both the inlet pipe and the drain pipe are connected to the inner wall of the interlayer, and a temperature monitor is fixedly connected to one side of the treatment tank.
[0007] Furthermore, a groove is provided on one side of the inner wall of the treatment tank, and a filter plate is fixed to the inner wall of the groove. The filter plate is disposed on one side of the sewage pipe.
[0008] Furthermore, a baffle is fixedly connected to one side of the L-shaped plate, and the rotating rod is rotatably connected to the center of the baffle. The baffle is located at the bottom of the first bevel gear.
[0009] Furthermore, a reinforcing plate is fixed to the inner wall of the L-shaped plate, and the reinforcing plate is inclined.
[0010] The technical effects and advantages of this utility model of a deep denitrification wastewater treatment equipment are as follows:
[0011] (1) The motor is started to drive the rotating rod and stirring rod to rotate. The rotating rod can agitate the sewage in the treatment tank, so that the chemical agents can react fully with the sewage. The rotating rod will drive the first bevel gear to rotate at the same time. When the first bevel gear rotates, it will drive the second bevel gear, the round rod, the round plate and the sliding rod to rotate together. When the sliding rod moves in a circle, it will drive the sliding frame, the vertical plate and the cleaning plate to move up and down. The cleaning plate can clean the sediment attached to the treatment tank. At the same time, the agitation will break up the sediment and further prevent the sediment from re-attaching, thus solving the problem of the inconvenience of cleaning the sediment on the inner wall of the treatment tank.
[0012] (2) By setting a temperature monitor, the temperature in the treatment tank can be monitored. When the water temperature in the treatment tank is lower than the predetermined temperature, warm water of appropriate temperature can be added into the jacket through the inlet pipe to keep the treatment tank at a suitable temperature, which is conducive to promoting the reaction of wastewater.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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] Example 1
[0023] Reference Figure 1-6 A deep denitrification wastewater treatment device includes a treatment tank 1. An L-shaped plate 2 is fixedly connected to the top of the treatment tank 1. A motor 3 is fixedly connected to one side of the L-shaped plate 2. A rotating rod 4 is fixedly connected to the output end of the motor 3. A stirring rod 5 is fixedly connected to the bottom of the rotating rod 4. A first bevel gear 6 is fixedly connected to the outer wall of the rotating rod 4. A second bevel gear 7 meshes with one side of the first bevel gear 6. A fixing rod 8 is fixedly connected to one side of the L-shaped plate 2. A collar 9 is fixedly connected to one side of the fixing rod 8. The inner wall of the collar 9 rotates. A round rod 10 is connected to one side of the second bevel gear 7. A round plate 11 is fixed to the other end of the round rod 10. A sliding rod 12 is fixed to one end of the round plate 11. A sliding frame 13 is slidably connected to the outer wall of the sliding rod 12. A vertical plate 14 is fixed to the bottom of the sliding frame 13. A cleaning plate 15 is fixed to the bottom of the vertical plate 14. The cleaning plate 15 is disposed on the inner wall of the treatment tank 1. A sewage pipe 17 is fixed to one side of the treatment tank 1. A valve is fixed to the outer wall of the sewage pipe 17.
[0024] To address the difficulty of cleaning sediment from the inner wall of treatment tank 1, when denitrification treatment of wastewater is required, wastewater can be poured into treatment tank 1, and an appropriate amount of chemical agent can be added. Then, motor 3 is started, driving the rotating rod 4 and stirring rod 5 at the bottom to rotate. The rotation of stirring rod 5 agitates the wastewater in treatment tank 1, ensuring a thorough reaction between the chemical agent and the wastewater. The rotation of rotating rod 4 drives the first bevel gear 6 on the outer wall to rotate. The rotation of the first bevel gear 6 drives the second bevel gear 7 meshing on one side to rotate. The rotation of the second bevel gear 7 then drives the circular rod 10, circular plate 11, and sliding rod 12 on one side to rotate together. By setting a fixing rod 8 and a collar 9, the circular rod 10 can be... The position of 0 is defined. When the circular plate 11 and the sliding rod 12 rotate, since the sliding rod 12 is slidably set on the inner wall of the sliding frame 13, the sliding frame 13 will move up and down as the sliding rod 12 moves in a circle. When the sliding frame 13 moves up and down, it will drive the bottom vertical plate 14 and the cleaning plate 15 to move up and down together. Since the shape of the cleaning plate 15 fits the inner wall of the treatment tank 1, the cleaning plate 15 will clean the sediment attached to the treatment tank 1 when it moves up and down. At the same time, it will be stirred to break up the sediment and further prevent the sediment from re-attaching. Then, the sewage mixed with chemical agents is allowed to stand until the sewage reaches the specified level. Then, the valve can be opened and the sewage in the treatment tank 1 can be discharged by opening the valve.
[0025] Reference Figure 2-3 The treatment pool 1 has an internal interlayer 18. A water inlet pipe 16 is provided at the top of one side of the treatment pool 1, and a drain pipe 19 is fixedly connected to the bottom of the other side of the treatment pool 1. Both the water inlet pipe 16 and the drain pipe 19 are connected to the inner wall of the interlayer 18. A temperature monitor 20 is fixedly connected to one side of the treatment pool 1.
[0026] By setting a jacket 18 inside the treatment tank 1, water can be added into the jacket 18 through the water inlet pipe 16. By setting a temperature monitor 20, the temperature inside the treatment tank 1 can be monitored. When the water temperature inside the treatment tank 1 is lower than the predetermined temperature, warm water of appropriate temperature can be added into the jacket 18 through the water inlet pipe 16 to maintain the treatment tank 1 at a suitable temperature, which is conducive to promoting the wastewater reaction.
[0027] Reference Figure 3 A groove is provided on one side of the inner wall of the treatment tank 1, and a filter plate 21 is fixed to the inner wall of the groove. The filter plate 21 is located on one side of the sewage pipe 17.
[0028] By setting grooves in the inner wall of the treatment tank 1, the filter plate 21 can be installed inside the grooves. When sewage is discharged from the sewage pipe 17, the water entering the sewage pipe 17 can be filtered by the filter plate 21 to prevent sediment from flowing out. Subsequently, the sediment in the treatment tank 1 can be cleaned by the staff.
[0029] Reference Figure 6 A baffle 22 is fixedly connected to one side of the L-shaped plate 2, and the rotating rod 4 is rotatably connected to the center of the baffle 22. The baffle 22 is located at the bottom of the first bevel gear 6.
[0030] By setting a baffle 22 on one side of the L-shaped plate 2, when the stirring rod 5 agitates the sewage, the baffle 22 can be used to protect the connection between the first bevel gear 6 and the second bevel gear 7, preventing water splashes from agitating from getting on the first bevel gear 6 and the second bevel gear 7, and effectively preventing the first bevel gear 6 and the second bevel gear 7 from being corroded by sewage.
[0031] Reference Figure 4 The inner wall of the L-shaped plate 2 is fixed with a reinforcing plate 23, which is inclined.
[0032] By setting an inclined reinforcing plate 23 inside the L-shaped plate 2, the reinforcing plate 23 can provide stable support for the L-shaped plate 2 when the motor 3 is running, making the L-shaped plate 2 more stable.
[0033] Working principle: To address the difficulty of cleaning sediment from the inner wall of treatment tank 1, when denitrification treatment of wastewater is required, wastewater can be poured into treatment tank 1, and an appropriate amount of chemical agent can be added. Then, motor 3 is started, driving the rotating rod 4 and stirring rod 5 to rotate. The rotation of stirring rod 5 agitates the wastewater in treatment tank 1, allowing the chemical agent to react fully with the wastewater. Baffle 22 protects the connection between the first bevel gear 6 and the second bevel gear 7, preventing water splashes from the agitation from contaminating the first bevel gear. On the second bevel gear 7, the rotating rod 4 rotates, which simultaneously drives the first bevel gear 6 to rotate. When the first bevel gear 6 rotates, it drives the second bevel gear 7, the round rod 10, the round plate 11, and the sliding rod 12 to rotate together. By setting the fixing rod 8 and the collar 9, the position of the round rod 10 can be limited. When the round plate 11 and the sliding rod 12 rotate, since the sliding rod 12 is slidably set on the inner wall of the sliding frame 13, when the sliding rod 12 moves in a circle, it will drive the sliding frame 13 to move up and down reciprocally. When the sliding frame 13 moves up and down reciprocally, it will drive the bottom vertical plate 1 4. The cleaning plate 15 moves up and down together. Since the shape of the cleaning plate 15 fits the inner wall of the treatment tank 1, the cleaning plate 15 will clean the sediment attached to the treatment tank 1 when it moves up and down. At the same time, it will stir to break up the sediment and further prevent the sediment from re-attaching. By setting a jacket 18 inside the treatment tank 1, water can be added into the jacket 18 through the water inlet pipe 16. By setting a temperature monitor 20, the temperature inside the treatment tank 1 can be monitored. When the water temperature in the treatment tank 1 is lower than the predetermined temperature, warm water of appropriate temperature can be added into the jacket 18 through the water inlet pipe 16 to maintain the treatment tank 1 at a suitable temperature, which is conducive to promoting the reaction of sewage. Then, the sewage with uniformly mixed chemical agents is left to stand until the sewage reaches the specified level. Then, the valve can be opened to discharge the sewage in the treatment tank 1. When the sewage is discharged from the sewage pipe 17, the water entering the sewage pipe 17 can be filtered by the filter plate 21 to prevent the sediment from flowing out. Then, the sediment in the treatment tank 1 can be cleaned by the staff.
[0034] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
