Description

Technical Field

[0001] This invention relates specifically to the field of wastewater treatment technology, and more specifically to a wastewater treatment device for soybean processing. Background Technology

[0002] Soybeans are annual herbaceous plants belonging to the genus *Glycine* of the legume family. Native to my country, they have been cultivated there for over 5000 years and are now widely grown throughout the country, particularly in Northeast China, North China, Shaanxi, Sichuan, and the lower reaches of the Yangtze River. The Yangtze River basin and Southwest China have the largest cultivation areas, with soybeans from Northeast China considered to be of the highest quality. Soybeans are rich in isoflavones, which can cut off the nutrient supply to cancer cells. They contain all eight essential amino acids, various vitamins, and trace elements, and can lower blood cholesterol, prevent hypertension, coronary heart disease, and arteriosclerosis. They also have beauty benefits. Soybeans contain linoleic acid, which promotes nerve development in children. Soybeans can be processed into tofu, soy milk, soy sauce, or fermented bean curd. The processing of soybeans requires washing with a weak acid solution, and the wastewater used needs to be treated for reuse.

[0003] Currently, the wastewater treatment equipment for soybean processing on the market is not only complex in structure but also has limited functionality. In particular, the slag removal device installed on the flotation tank cannot be used continuously, which leads to a decrease in the efficiency of soybean wastewater treatment.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1

[0025] Please see Figures 1-4 In this embodiment of the invention, a wastewater treatment device for soybean processing includes a flotation tank 10, a scum cleaning mechanism 20, and a scraper mechanism 30. The scum cleaning mechanism 20 is installed on the upper side of the flotation tank 10 and is used to clean the scum on the surface of the flotation tank 10 to keep the interior of the flotation tank 10 clean. The scum cleaning mechanism 20 includes a conveyor belt and several cleaning mechanisms 21 disposed on the surface of the conveyor belt. The conveyor belt drives the cleaning mechanisms 21 to move. When the cleaning mechanism 21 moves to the bottom of the conveyor belt, the cleaning mechanism 21 carries away the scum from the upper part of the flotation tank 10. To keep the interior of the flotation tank 10 clean; the scraper mechanism 30 is installed on one side of the flotation tank 10. The scraper mechanism 30 includes a frame 31 fixedly installed on the flotation tank 10, an installation roller 32 rotatably installed on the frame 31, and a number of scrapers 33 evenly distributed on the surface of the installation roller 32. The installation roller 32 rotates on the frame 31 to drive the scrapers 33 to rotate. When the scrapers 33 come into contact with the cleaning mechanism 21, the scrapers 33 scrape off the scum collected by the cleaning mechanism 21 and clean the cleaning mechanism 21, thereby maintaining the cleanliness of the cleaning mechanism 21 and enabling the cleaning mechanism 21 to continuously remove scum.

[0026] Furthermore, in this embodiment, the mounting roller 32 has several grooves inside, the scraper 33 is slidably installed inside the grooves, and a drive screw 36 is rotatably installed inside the grooves. The drive screw 36 is threadedly connected to the scraper 33, and the drive screw 36 controls the sliding distance of the scraper 33 in the grooves. Also, a cleaning cotton strip 37 is embedded in the contact surface between the grooves and the scraper 33. The cleaning cotton strip 37 is an elastic structure. It can be understood that when the scraper 33 is retracted into the grooves, the surface of the scraper 33 contacts the cleaning cotton strip 37, and the cleaning cotton strip 37 cleans the scraper 33 to keep the surface of the scraper 33 clean.

[0027] Furthermore, in the embodiment of the application, a control shaft is rotatably mounted at the center of the mounting roller 32, a second bevel gear 39 is fixedly mounted on the control shaft, and a first bevel gear 38 is fixedly mounted at the end of the drive screw 36, the first bevel gear 38 meshing with the second bevel gear 39; a cleaning motor (not shown in the figure) is also fixedly mounted inside the mounting roller 32, and the output end of the cleaning motor is fixedly connected to the control shaft for driving the control shaft to rotate, thereby adjusting the sliding of the scraper 33.

[0028] In this embodiment, the cleaning mechanism 21 includes a base 211 fixedly mounted on the conveyor belt and an adsorption plate 212 rotatably mounted on the base 211. The bottom of the adsorption plate 212 is connected to the base 211 by several springs. It can be understood that the adsorption plate 212 can rotate on the base 211. When the scraper 33 contacts the adsorption plate 212, the scraper 33 squeezes the adsorption plate 212, causing the spring to deform. Under the elastic force of the spring, the adsorption plate 212 and the scraper 33 are tightly attached, so that the scraper 33 can effectively scrape off the scum adsorbed on the surface of the adsorption plate 212.

[0029] Furthermore, in this embodiment, a drive shaft 22 for driving the conveyor belt to rotate is provided on the inner side of the conveyor belt, and a drive motor 23 is fixedly installed on the outer side of the pool body 11. The output end of the drive motor 23 is fixedly connected to the drive shaft 22 to drive the conveyor belt to move. In addition, pulleys are fixedly installed on both the drive shaft 22 and the rotating shaft of the mounting roller 32. The two pulleys are connected by a synchronous belt 34 to drive the mounting roller 32 to rotate synchronously when the conveyor belt moves.

[0030] In this embodiment, the pool body 11 is provided with an inlet 12 for adding wastewater to be treated, and a drain outlet 16 is provided on one side of the bottom of the pool body 11 for discharging waste residue from the bottom of the pool body 11. The lower part of the pool body 11 is provided with a slag discharge mechanism for discharging the waste residue from the bottom of the pool body 11 from the drain outlet 16. The slag discharge mechanism includes an adjusting screw 17 rotatably installed at the bottom of the pool body 11, a baffle 15 slidably installed at the bottom of the pool body 11, and a rotary motor 13 for controlling the rotation of the adjusting screw 17. The baffle 15 is threadedly connected to the adjusting screw 17, and the output end of the rotary motor 13 is fixedly connected to the adjusting screw 17. The rotary motor 13 controls the adjusting screw 17 to rotate, thereby driving the baffle 15 to slide at the bottom of the pool body 11 and discharging the waste residue from the bottom of the pool body 11 from the drain outlet 16.

[0031] In addition, a baffle 15 is provided on the pool body 11 at the sewage outlet 16. The baffle 15 is used to close the sewage outlet 16 to prevent sewage from leaking into the pool body 11.

The scum cleaning mechanism 20 includes a conveyor belt and several cleaning mechanisms 21 disposed on the surface of the conveyor belt. The conveyor belt drives the cleaning mechanisms 21 to move. When the cleaning mechanism 21 moves to the bottom of the conveyor belt, the cleaning mechanism 21 carries away the scum from the upper part of the flotation tank 10.

The installation roller 32 rotates on the frame 31 to drive the scrapers 33 to rotate. When the scrapers 33 come into contact with the cleaning mechanism 21, the scrapers 33 scrape off the scum collected by the cleaning mechanism 21 and clean the cleaning mechanism 21, thereby maintaining the cleanliness of the cleaning mechanism 21 and enabling the cleaning mechanism 21 to continuously remove scum.

When the scraper 33 contacts the adsorption plate 212, the scraper 33 squeezes the adsorption plate 212, causing the spring to deform. Under the elastic force of the spring, the adsorption plate 212 and the scraper 33 are tightly attached, so that the scraper 33 can effectively scrape off the scum adsorbed on the surface of the adsorption plate 212.
