Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wastewater treatment technology, and in particular to a wastewater treatment device for cogeneration. Background Technology
[0002] Cogeneration inevitably generates wastewater, which must be treated at a wastewater treatment plant before it can be discharged. Wastewater treatment plants, also known as sewage treatment plants, are often referred to as treatment stations when they are located in factories. When the effluent is discharged into the city's drainage system, the treatment station is actually a pretreatment facility. A wastewater treatment plant is a complex system composed of multiple unit processes. The cost and efficiency of each unit process are interconnected and influence each other, ultimately determining the cost and efficiency of the entire system.
[0003] In existing wastewater treatment plants for cogeneration, the dosing of chemicals to wastewater mostly involves introducing the chemicals into the wastewater and then using a motor to drive a stirring mechanism to mix the wastewater and chemicals. This mixing method creates vortices in the wastewater, which increases the time required for the chemicals and wastewater to mix thoroughly. Therefore, there is an urgent need for a wastewater treatment plant for cogeneration to solve this problem. Utility Model Content
[0004] The purpose of this invention is to provide a wastewater treatment device for combined heat and power generation to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a wastewater treatment device for cogeneration, comprising a treatment tank for cogeneration wastewater treatment and two agitating plates for wastewater treatment. The top surface of the treatment tank has two symmetrically formed strip grooves, and sliders are slidably connected in the two strip grooves. A vertical plate is fixedly installed on the top surface of the sliders.
[0006] A lead screw is installed laterally and rotatably inside the strip groove, and a slider is threadedly connected to the outer wall of the lead screw;
[0007] A horizontal plate is fixedly installed between the two vertical plates, and a horizontal pipe and a pesticide spray pipe are installed between the top and bottom surfaces of the horizontal plate.
[0008] The two agitator plates are symmetrically fixedly installed at the bottom of the horizontal plate, and multiple rectangular holes are provided on the side walls of the agitator plates. A guide plate is fixedly installed at an angle in each of the multiple rectangular holes, and the guide plates installed on the two agitator plates are set at opposite angles.
[0009] Preferably, a circulation pipe is installed on the outer wall of the processing box, and a circulation pump and a filter cartridge are installed on the wall of the circulation pipe.
[0010] Preferably, a water inlet pipe is installed above one side of the inner wall of the treatment tank, and the circulation pipe is connected to the water inlet pipe.
[0011] Preferably, the side wall of the filter cylinder is provided with an arc-shaped hole, and an arc-shaped plate is slidably installed inside the arc-shaped hole.
[0012] Preferably, a circular frame is fixedly installed on the inner wall of the arc-shaped plate, and a filter screen is fixedly installed inside the circular frame.
[0013] Preferably, two limiting blocks are symmetrically fixedly installed on the side wall of the slider, and two limiting grooves are symmetrically opened on the inner wall of the strip groove.
[0014] Preferably, the two limiting blocks fixedly installed on the side wall of the slider are slidably connected to the inside of the limiting groove opened on the inner wall of the strip groove.
[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:
[0016] This wastewater treatment device for cogeneration benefits from the arrangement of horizontal pipes above the horizontal plate and chemical spray pipes below the horizontal plate, with the chemical spray pipes located between two agitator plates. This allows the chemical spray pipes to move synchronously with the agitator plates, spraying the chemicals into the wastewater, thereby further improving the mixing effect between the wastewater and the chemicals.
[0017] This wastewater treatment device for cogeneration benefits from the configuration of a lead screw, slider, horizontal plate, two agitator plates, and multiple guide plates. The lead screw drives the slider, which is threaded onto its wall, to move synchronously. Subsequently, the slider drives the horizontal plate and the two agitator plates to move synchronously. The guide plate on one agitator plate diverts the wastewater below the treatment tank upwards, while the guide plate on the other agitator plate causes the wastewater inside the treatment tank to tumble downwards. This up-and-down movement of the wastewater accelerates the mixing of wastewater and chemicals within the treatment tank, thereby further improving the wastewater treatment effect.
[0018] This wastewater treatment device for cogeneration benefits from the arrangement of a circulation pipe, a circulation pump, a filter cartridge, and an inlet pipe. One end of the circulation pipe's inlet is located below the side wall of the treatment tank. Therefore, the wastewater below the treatment tank can be pumped into the inlet pipe and then discharged back into the treatment tank by the circulation pump, thereby achieving further circulation of the wastewater and further improving the wastewater treatment effect.
[0019] Compared with existing technologies, this wastewater treatment device for cogeneration can improve the mixing efficiency of wastewater and reagents, and further improve the treatment effect of wastewater. Attached Figure Description

In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0029] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.
[0030] like Figures 1 to 4The main structure of a wastewater treatment device for cogeneration is a wastewater treatment tank 1 and two agitator plates 9. Two strip-shaped grooves 2 are symmetrically opened on the top surface of the treatment tank 1. Slider plates 4 are slidably connected within the two strip-shaped grooves 2. A vertical plate 5 is fixedly installed on the top surface of the slider 4. A lead screw 3 is horizontally rotatably installed within the strip-shaped grooves 2, and the slider 4 is threaded to the outer wall of the lead screw 3. The two agitator plates 9 are symmetrically fixedly installed at the bottom of a horizontal plate 6. Multiple rectangular holes are opened on the side walls of each agitator plate 9, and guide plates 10 are obliquely fixedly installed within each of these rectangular holes. The guide plates 10 installed on the two agitator plates 9 are respectively... With the opposite angles, thanks to the screw 3, slider 4, horizontal plate 6, two agitator plates 9, and multiple guide plates 10, the screw 3 drives the slider 4, which is threaded onto its wall, to move synchronously. Then, the slider 4 drives the horizontal plate 6 and the two agitator plates 9 to move synchronously. The guide plate 10 on one of the agitator plates 9 will guide the sewage below the treatment tank 1 to turn upwards, while the guide plate 10 on the other agitator plate 9 will cause the sewage inside the treatment tank 1 to turn downwards. In this way, by turning the sewage up and down, the mixing of sewage and chemicals in the treatment tank 1 is accelerated, thereby further improving the sewage treatment effect.
[0031] A horizontal plate 6 is fixedly installed between two vertical plates 5. A horizontal pipe 7 and a chemical spray pipe 8 are installed between the top and bottom surfaces of the horizontal plate 6. Thanks to the horizontal pipe 7 above the horizontal plate 6 and the chemical spray pipe 8 below the horizontal plate 6, and the fact that the chemical spray pipe 8 is located between two stirring plates 9, the chemical spray pipe 8 can spray the chemical into the sewage in sync with the movement of the stirring plates 9, thereby further improving the mixing effect of sewage and chemical.
[0032] A circulation pipe 12 is installed on the outer wall of the treatment tank 1, and a circulation pump 13 and a filter cartridge 14 are installed on the pipe wall of the circulation pipe 12. An inlet pipe 16 is installed on the upper side of one side of the inner wall of the treatment tank 1, and the circulation pipe 12 is connected to the inlet pipe 16. Thanks to the arrangement of the circulation pipe 12, circulation pump 13, filter cartridge 14 and inlet pipe 16, and the inlet end of the circulation pipe 12 is located below the side wall of the treatment tank 1, the sewage below the treatment tank 1 can be pumped into the inlet pipe 16 by the circulation pump 13 and discharged back into the interior of the treatment tank 1, thereby achieving further circulation of sewage and further improving the sewage treatment effect.
[0033] The side wall of the filter cylinder 14 has an arc-shaped hole, and an arc-shaped plate 15 is slidably installed inside the arc-shaped hole. A circular frame 17 is fixedly installed on the inner wall of the arc-shaped plate 15, and a filter screen 18 is fixedly installed inside the circular frame 17. The circulation pump 13 is started to draw sewage into the circulation pipe 12 and pass the sewage into the filter cylinder 14. At the same time, the sewage is filtered by the filter screen 18 installed inside the filter cylinder 14, and the filtered sewage is passed into the treatment tank 1 again through the inlet pipe 16. When too much debris accumulates on the side wall of the filter screen 18, the circulation pump 13 can be stopped, the arc-shaped plate 15 can be pulled out, and the filter screen 18 can be removed and processed simultaneously.
[0034] Two limiting blocks 11 are symmetrically fixedly installed on the side wall of the slider 4, and two limiting grooves are symmetrically opened on the inner wall of the strip groove 2. The two limiting blocks 11 fixedly installed on the side wall of the slider 4 are slidably connected to the inside of the limiting grooves opened on the inner wall of the strip groove 2. Thanks to the setting of the two limiting blocks 11, the sliding direction of the slider 4 can be limited, and the stability of the slider 4 during sliding can be further improved.
[0035] Working principle
[0036] In operation, the wastewater treatment device for cogeneration first introduces the chemical agent into the horizontal pipe 7, which then guides the agent into the spray pipe 8 and sprays it into the wastewater. Simultaneously, two lead screws 3 are activated, which in turn drive two sliders 4 to move synchronously. The sliders 4 then drive the horizontal plate 6 to move laterally, which in turn drives two agitator plates 9 at the bottom of the horizontal plate 6 to move laterally. This, along with two guide plates 10 at opposite angles on the agitator plates 9, stirs the wastewater in the treatment tank 1 upwards and downwards, respectively, ensuring thorough mixing of the wastewater and the chemical agent. Meanwhile, the circulation pump 13 is activated to draw the wastewater into the circulation pipe 12 and then into the filter cylinder 14. The wastewater is filtered by the filter screen 18 inside the filter cylinder 14 and then reintroduced into the treatment tank 1 through the inlet pipe 16. When too much debris accumulates on the side wall of the filter screen 18, the circulation pump 13 is stopped, the arc plate 15 is pulled out, and the filter screen 18 is removed and disposed of.
