Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly relates to a sewage treatment device for industrial use. Background Art

[0002] The basic process of industrial sewage treatment usually includes several stages such as physical treatment, chemical treatment, biological treatment, and advanced treatment. Among them, chemical treatment includes neutralization, coagulation precipitation, oxidation-reduction, etc., and devices such as neutralization reactors, coagulation stirring tanks, and oxidation towers are used. The purpose of the neutralization reaction is to adjust the pH value of the sewage, which is usually achieved by adding acid or alkali. During the reaction process, acid and alkali react to form salt and water. For example, sulfuric acid and sodium hydroxide react to form sodium sulfate.

[0003] In the prior art, the addition of powder depends on manual experience, which is prone to overdosage or underdosage, resulting in pH fluctuations. Moreover, the powder is scattered on the surface of the sewage, and simple agitation is not sufficient to quickly and fully dissolve the powder, so the neutralization reaction of the sewage is not sufficient. Summary of the Invention

The top of the quantitative cylinder 701 abuts against the bottom of the chemical powder cylinder 3. A weighing cavity in a ring structure is opened at the bottom of the quantitative cylinder 701. A quantitative plate 703 is slidably installed in the weighing cavity. Multiple filter holes are opened at the top of the quantitative plate 703. Multiple steel balls 705 are rolled on the top of the quantitative plate 703. Multiple convex strips 704 are fixedly installed at the top of the quantitative plate 703 in a circumferential and uniform manner. A guide block 710 in a conical structure is fixedly installed at the bottom of the quantitative plate 703. A first groove is opened in the middle of the bottom of the quantitative cylinder 701. A connecting shaft 707 in a stepped structure is fixedly installed in the first groove. A second groove is opened at the top of the connecting shaft 707. A storage battery and an electric telescopic rod 702 are fixedly installed in the second groove. A second plug block 709 is fixedly embedded in the second groove. The telescopic end of the electric telescopic rod 702 passes through the second plug block 709 and a connecting block 708 is fixedly installed at the end. Two push rods 706 are symmetrically fixedly installed at the bottom of the connecting block 708. The other ends of the two push rods 706 both pass through the outer surfaces of the connecting shaft 707 and the guide block 710 and are fixedly installed with the bottom of the quantitative plate 703. An impeller 10 is fixedly installed at the center of the bottom end of the connecting shaft 707;

[0030] On both sides of the surface of the medicine mixing cylinder 1, there are respectively a water inlet 101 and a water outlet 103. At the bottom of the medicine mixing cylinder 1, there is a slag discharge port 102. The chemical powder cylinder 3 is made of transparent material, and the bottom of the chemical powder cylinder 3 is of an open structure. The bottoms of both the medicine mixing cylinder 1 and the chemical powder cylinder 3 are of a funnel-shaped structure. A water pump 2 is fixedly installed in the water inlet 101. The water outlet end of the water pump 2 is connected to a water pipe, and the other end of the water pipe is arranged on one side of the impeller 10. An outlet pipe 9 is fixedly installed outside the water outlet 103. A slag collection box 8 is connected to the slag discharge port 102 by internal threads. Bottom brackets 13 and first stoppers 16 are respectively fixedly installed in the slag discharge port 102 and the open bottom of the chemical powder cylinder 3.

The material discharge switch 15 is of a fan-shaped structure. Each push rod 706 is of a J-shaped structure, and two avoidance grooves for avoiding the push rod 706 are symmetrically formed on the surface of the connecting shaft 707.

[0031] During use, the water inlet end of the water pump 2 is connected to the previous process device of the sewage treatment, and the outlet pipe 9 is connected to the next process device of the sewage treatment. By setting the metering mechanism 7, the electric telescopic rod 702 is started to control the height of the metering plate 703 in the metering cylinder 701, so that the volume of the weighing chamber in the metering cylinder 701 meets the volume of the required medicament powder. After the metering cylinder 701 is filled, the electric telescopic rod 702 is used to control the metering plate 703 to descend until the diversion block 710 extends out from the bottom of the metering cylinder 701. Then, the medicament powder is evenly scattered on the surface of the impeller 10 through the diversion block 710. The water pump 2 continuously pumps the sewage after impurity removal onto the surface of the impeller 10 to drive the impeller 10 to rotate, and at the same time, the medicament powder is quickly dissolved under the impact of the sewage, improving the sufficiency of the medicament powder dissolution.

[0032] By setting the impeller 10 to be fixedly connected to the metering cylinder 701, as the impeller 10 rotates, the metering cylinder 701 is driven to rotate synchronously through the connecting shaft 707. The steel balls 705 inside the metering cylinder 701 roll irregularly in the metering cylinder 701, so that the agglomerated medicament powder is fully crushed. A plurality of convex strips 704 are provided to block the steel balls 705, so that the steel balls 705 intermittently impact the metering plate 703 during the rolling process, enabling the medicament powder to pass more smoothly through the filter holes of the metering plate 703 and then enter the medicine mixing cylinder 1, improving the utilization rate of the medicament powder.

[0033] In this embodiment, a servo motor 4 and a controller 5 are fixedly installed at the top of the chemical powder cartridge 3. A second stirring mechanism 14 is provided inside the chemical powder cartridge 3. The second stirring mechanism 14 is used to assist the powder in flowing downward and level the top of the powder, facilitating the accurate observation of the remaining amount of the powder. The second stirring mechanism 14 includes a second main shaft 1401. The second main shaft 1401 is rotatably installed inside the chemical powder cartridge 3 and its bottom end passes through the first plug 16 and is fixedly installed at the rotation center of the top of the blanking switch 15. A plurality of second stirring shafts 1402 adapted to the inner wall of the chemical powder cartridge 3 are fixedly installed on the surface of the second main shaft 1401 near the bottom end. A retaining ring 1409 is fixedly sleeved on the surface of the second main shaft 1401. Two limiting ridges 1403 are provided on the surface of the second main shaft 1401. A counterweight 1405 is slidably sleeved on the surface of the second main shaft 1401. A chute adapted to the limiting ridge 1403 is provided on the inner surface of the inner ring of the counterweight 1405. A second scraper 1404 is fixedly installed on one side of the counterweight 1405. A fourth groove is provided on the top of the counterweight 1405. A magnet 1406 is fixedly installed in the fourth groove. A sealing cover 1407 adapted to the fourth groove is fixedly installed on the surface of the magnet 1406. An electromagnet 1408 is fixedly installed at the top inside the chemical powder cartridge 3.

[0034] During use, the controller 5 is provided with a PLC control system for controlling the operation of the servo motor 4, the electric telescopic rod 702 and the electromagnet 1408. Starting the servo motor 4 can drive the second main shaft 1401 to rotate, and then drive the blanking switch 15 to rotate, so that the first plug 16 is intermittently aligned with the blanking hole 18 opened in the metering cylinder 701 for blanking. As the second main shaft 1401 rotates, it drives a plurality of second stirring shafts 1402 to stir the powder, making the blanking more smooth. At the same time, the second scraper 1404 arranged on the top of the powder rotates with the second main shaft 1401 and slides down along the second main shaft 1401 as the powder decreases, thereby leveling the top of the powder. The surface of the second scraper 1404 is uneven, forming a large frictional force with the powder, preventing the second scraper 1404 from being buried inside the powder, facilitating the staff to clearly observe the remaining amount of the powder, and improving the convenience of equipment use; when loading the powder, first start the electromagnet 1408 to generate a suction force on the magnet 1406, and then bring the second scraper 1404 to the top inside the chemical powder cartridge 3 to prevent the powder from burying it.

[0035] In this embodiment, a first stirring mechanism 12 is provided in the medicine mixing cylinder 1. The first stirring mechanism 12 includes a first main shaft 1201 and two first scraping plates 1203. The bottom end of the first main shaft 1201 is rotatably installed on the top of the bottom bracket 13. The top end of the first main shaft 1201 is fixedly installed at the rotation center of the bottom of the impeller 10. A plurality of first stirring shafts 1202 adapted to the inner wall of the medicine mixing cylinder 1 are symmetrically and fixedly installed on the surface of the first main shaft 1201. The two first scraping plates 1203 are respectively fixedly installed at the ends of the corresponding first stirring shafts 1202. The two first scraping plates 1203 are symmetrically arranged and are in contact with the inner wall of the medicine mixing cylinder 1. Cleaning blocks 17 are fixedly installed at the tops of the two first scraping plates 1203. A filter box 11 is fixedly installed in the medicine mixing cylinder 1. The filter box 11 covers the periphery of the water outlet 103. A plurality of through holes for filtering solid reactants are formed at the bottom of the filter box 11. The bottom of the filter box 11 is flush with the top of the cleaning block 17.

[0036] During use, by setting the first stirring mechanism 12, solid reactants will be generated as a result of the chemical reaction between the medicine powder and the sewage. The filter box 11 can isolate the solid reactants in the medicine mixing cylinder 1 to prevent them from entering the next process. The impurities accumulated on the inner wall of the medicine mixing cylinder 1 can be scraped off by the first scraping plates 1203 and fall into the slag collection box 8 below for convenient centralized treatment later. As the first scraping plates 1203 rotate, the cleaning blocks 17 can also be driven to clean the impurities accumulated at the bottom of the filter box 11 to keep it unobstructed. Moreover, with the operation of the first stirring mechanism 12, the reaction between the medicine powder and the sewage can be further accelerated.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
