DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] A sewage treatment equipment, such as Figures 1-6 As shown, it includes two symmetrically arranged mounting frames 1, and a treatment tank 2, a first mounting plate 3 and a second mounting plate 4 are arranged between the two mounting frames 1 from bottom to top. A driving mechanism 5 is provided between the first mounting plate 3 and the second mounting plate 4, and two stirring mechanisms 6 are provided on the driving mechanism 5. The stirring mechanism 6 is located in the treatment tank 2, and a detection mechanism 7 is also provided on the treatment tank 2. A feeding mechanism 8 is also provided on the stirring mechanism 6. The feeding mechanism 8 is used to add purification and other related agents to the sewage in the treatment tank 2 to treat the sewage, and the set driving mechanism 5 can drive the two stirring mechanisms 6 to stir the sewage, so that the agents can be better and faster integrated with the sewage, thereby speeding up the treatment efficiency. A controller 9 is provided on the mounting frame 1, and the controller 9 is used to receive the detection results of the detection mechanism 7, and adjust the feeding mechanism 8 to perform feeding operations according to the results. The controller 9 can not only be used to control all electrical components on the treatment equipment, thereby facilitating operation, but also obtain the detection results of the detection mechanism 7, and judge whether the sewage in the treatment tank 2 is treated to meet the standards based on the detection results. If it does not meet the standards, the detection results can be used to calculate the amount of medicine that needs to be continued to be added to control the opening time of the electric control switch valve 804 on the feeding mechanism 8. For example, to treat the ammonia nitrogen content in sewage, potassium permanganate chemical agent is installed in the feeding mechanism 8, and the initial ammonia nitrogen content G1 of the sewage is first detected by the detector 705 of the detection mechanism 7 (the detector 705 can be an ammonia nitrogen detector), and then the obtained ammonia nitrogen content G1 is compared with the standard value H1 of the ammonia nitrogen content in sewage preset in the controller 9. If G1≥H1, it indicates that the ammonia nitrogen content in the sewage does not meet the standard and needs to be treated, otherwise no treatment is required; the steps that need to be treated are to calculate the time T1 for the electric control switch valve 804 on the corresponding feeding mechanism 8 to open by the formula T1=|G1-H1|*α1, and to add the corresponding content of potassium permanganate chemical agent to purify the sewage. α1 is the conversion coefficient corresponding to the ammonia nitrogen content in the sewage, and the conversion coefficient α1 can be obtained according to experimental data, so that the amount of medicine input can be accurately controlled to make the sewage treatment more accurate.

[0036] like Figure 2As shown, the driving mechanism 5 includes a mounting cylinder 501 rotatably connected to the first mounting plate 3 and a mounting shaft 502 rotatably connected to the second mounting plate 4. The mounting shaft 502 extends through the mounting cylinder 501 into the processing tank 2. Two stirring mechanisms 6 are respectively mounted on the outer walls of the mounting cylinder 501 and the mounting shaft 502. The mounting cylinder 501 is further provided with a first turntable 503, and the mounting shaft 502 is provided with a second turntable 504. The top of the first turntable 503 is provided with a circle of first end face teeth 505, and the second turntable 504 is provided with a circle of first end face teeth 505. A circle of second end face teeth 506 is provided at the bottom, and a rotating shaft 507 is also provided on the mounting frame 1. A first driving motor 508 is provided at one end of the rotating shaft 507, and a gear 509 is provided at the other end of the rotating shaft 507. The gear 509 is arranged between the first end face teeth 505 and the second end face teeth 506, and the gear 509 is engaged with the first end face teeth 505 and the second end face teeth 506. A plurality of threaded mounting holes 510 are also provided on the first turntable 503, and the feeding mechanism 8 can be detachably mounted in the threaded mounting hole 510. The first drive motor 508 drives the rotating shaft 507 to rotate, driving the gear 509 to rotate. Since the first end face teeth 505 and the second end face teeth 506 are both meshed with the gear 509, the rotation of the gear 509 will drive the two turntables to rotate. Since the gear 509 is arranged between the two turntables, the rotation directions of the first turntable 503 and the second turntable 504 will be opposite, and the rotation direction of the stirring mechanism 6 installed on the mounting cylinder 501 will be opposite to the rotation direction of the stirring mechanism 6 installed on the mounting shaft 502. The two stirring mechanisms 6 are arranged up and down in the treatment tank 2, so that the sewage in the treatment tank 2 can be layered and stirred, and the stirring directions are also different, which can improve the stirring efficiency and make the medicine and sewage mixed more evenly and thoroughly. In addition, the feeding mechanism 8 for adding medicine is installed on the first turntable 503. When the medicine is added, it will also rotate with the rotation of the first turntable 503, so that the medicine can be evenly scattered in the treatment tank 2, which is more conducive to the mixing of the medicine and sewage.

[0037] like Figure 3As shown, the stirring mechanism 6 includes a sleeve 601, and fixed plates 602 are symmetrically provided on both sides of the sleeve 601. A mounting groove 603 is provided on the sleeve 601 below the fixed plate 602, and a slide plate 604 is slidably connected in the mounting groove 603. A first waterproof cylinder 605 is also provided in the mounting groove 603, and the output end of the first waterproof cylinder 605 is connected to the slide plate 604. Two connecting plates 606 are rotatably connected to the side wall of the slide plate 604. A slide groove 607 is also provided on the fixed plate 602, and a slider 608 is provided in the slide groove 607. A stirring plate 609 is installed on the slider 608. The end of the connecting plate 606 is rotatably connected to the side wall of the stirring plate 609. A first inclined plate 610 and a second inclined plate 611 are staggered on the stirring plate 609. The inclination angle of the first inclined plate 610 is opposite to the inclination angle of the second inclined plate 611, and the first inclined plate 610 and the second inclined plate 611 are both provided with a plurality of water permeable holes 612. When the stirring mechanism 6 rotates and stirs, the first waterproof cylinder 605 expands and contracts, driving the slide plate 604 to move back and forth within the mounting groove 603. With the cooperation of the connecting plate 606, it drives the stirring plate 609 to move back and forth within the chute 607. In this way, when the stirring mechanism 6 stirs, the sewage on the horizontal surface can also be agitated by the lateral back and forth movement of the stirring plate 609, which can achieve more comprehensive agitation of the sewage, promote the mixing and dispersion of suspended matter in the water, the thorough mixing of the reagent and sewage, and the more uniform distribution of dissolved oxygen in the water, thereby further facilitating the sewage treatment operation. The staggered arrangement of the first inclined plate 610 and the second inclined plate 611 can increase the contact area with the water, ensuring thorough agitation, while the permeable holes 612 can reduce the resistance of the water to the inclined plates during agitation.

[0038] like Figure 4 、 Figure 5As shown, the detection mechanism 7 includes a detection box 701 connected to the processing tank 2, and a slot 702 is provided on the top of the inner wall of the detection box 701. A second waterproof cylinder 703 is provided in the slot 702. The output end of the second waterproof cylinder 703 is connected to a third mounting plate 704. The third mounting plate 704 is slidably connected to the slot 702, and a number of detectors 705 are installed on the third mounting plate 704. A third waterproof cylinder 706 is also provided on the inner wall of the detection box 701, and an arc plate 707 is provided at the output end of the third waterproof cylinder 706. The curvature of the arc plate 707 is the same as the curvature of the inner wall of the processing tank 2, and a layer of sealing gasket 708 is provided on the outer wall of the arc plate 707. When inspection is required, the third waterproof cylinder 706 can be driven to contract, driving the curved plate 707 to move, so that part of the sewage in the treatment tank 2 will enter the inspection box 701. At this time, the second waterproof cylinder 703 is driven to extend, and the detector 705 is extended into the sewage to detect whether the various indicators in the sewage meet the standards. The detector 705 can be set with corresponding detection equipment according to the inspection indicators. When the inspection is completed, the second waterproof cylinder 703 retracts and each detector 705 is recovered into the slot 702. At the same time, the third waterproof cylinder 706 is extended and retracted, and the water entering the inspection box 701 is discharged through the squeezing operation of the curved plate 707, waiting for the next inspection.

[0039] like Figure 6 As shown, the feeding mechanism 8 includes a storage barrel 801, the outer wall of which is provided with a threaded groove 802, which cooperates with the threaded mounting hole 510. The bottom of the storage barrel 801 is provided with a discharge funnel 803, and the discharge funnel 803 is provided with an electrically controlled on / off valve 804. The feeding mechanism 8 can be multiple, and the storage barrel 801 of each feeding mechanism 8 is placed with the required pharmaceutical agent and is mounted on the first rotating disk 503 via the threaded groove 802. The controller 9 can control the opening time of the electrically controlled on / off valve 804 of the required pharmaceutical agent according to the calculated results, thereby accurately feeding the material.

[0040] When in use, the sewage is put into the treatment tank 2, and the third waterproof cylinder 706 is first started to contract, driving the curved plate 707 to move, and part of the sewage in the treatment tank 2 is introduced into the detection box 701. At this time, the second waterproof cylinder 703 is driven to extend, and the detector 705 is extended into the sewage. The initial content of various indicators that need to be purified in the sewage is detected by each detector 705, and then the curved plate 707 is restored to its original position, and the first drive motor 508 is started. Through the engagement of the gear 509 with the two end teeth, the two stirring mechanisms 6 are driven to rotate in the opposite direction in the treatment tank 2 to stir the sewage. During stirring, the first waterproof cylinder 605 can be controlled to extend and retract to drive the slide plate 604 to move back and forth in the installation groove 603. With the cooperation of the connecting plate 606, the stirring plate 609 is driven. At the same time, the controller 9 calculates the amount of reagent required for each indicator based on the initial content of each indicator detected, and then controls the corresponding detection mechanism 7 to open the time for the electric control switch valve 804 to open, and puts the reagent into the sewage to mix with the sewage; after a certain period of time, the third waterproof cylinder 706 is started to contract, and the sewage is tested for the second time by the detector 705. If there is still a situation where a certain indicator does not meet the standard, the controller 9 continues to calculate the amount of reagent required for the project, and continues to control the opening time of the electric control switch valve 804 under the project indicator to treat the sewage until all the indicators that need to be purified for the sewage meet the requirements, and then the sewage is discharged for the next process.

[0041] A sewage treatment system is implemented by the above-mentioned sewage treatment equipment.

[0042] The above content is merely an example and explanation of the concept of the present invention. Those skilled in the art may make various modifications or additions to the described specific embodiments or replace them in a similar manner.
