Description

Technical Field

[0002] Industrial wastewater includes production wastewater and sewage, etc. It refers to wastewater and waste liquid generated in the industrial production process, which contains industrial production materials, intermediate products, by-products and other pollutants generated in the production process that are lost with water. There are many types of industrial wastewater with complex components. Since industrial wastewater often contains a variety of toxic substances, it pollutes the environment and has great harm to human health. Therefore, it needs to be treated to meet the standards before it can be discharged.

[0003] Industrial wastewater can be treated by activated carbon adsorption filtration. Activated carbon has a lot of micropores, a huge specific surface area, and a strong physical adsorption capacity. It can effectively adsorb organic pollutants in wastewater, and some oxygen-containing functional groups are formed on the non-crystalline parts of the activated carbon surface during the activation process. These groups make the activated carbon have the properties of chemical adsorption and catalytic oxidation and reduction, and can effectively remove some metal ions in wastewater. Referring to the authorized patent, patent number: CN212174515U discloses an industrial wastewater filter tank, including a tank body, and an inlet and an outlet connected to the tank body. Through the industrial wastewater filter tank, the activated carbon can be easily unloaded from the upper part of the filter tank. Although the speed of activated carbon unloading can be increased, when the industrial wastewater is oxidized and filtered, the industrial wastewater transmitted to the tank body can only pass through the activated carbon vertically, and the contact oxidation time is short, resulting in poor oxidation filtration effect.

[0028] The working principle and process of this utility model are as follows:

[0029] First, the first motor 10 is operated to drive the linkage gear 8 to rotate. The rotation of the linkage gear 8 drives the annular gear plate 7 and the limiting ring plate 5 to rotate synchronously. The rotation of the limiting ring plate 5 drives the eight mounting frames 18 and the rollers 19 to run around the tank body 1. Since the lengths of the eight mounting frames 18 are not equal, the tank body 1 can be supported by the support legs 16 and the locking wheels 17 to swing in a circle inside the limiting ring plate 5. When the external industrial waste water is transmitted to the tank body 1 through the feed pipe 2, the activated carbon on the supporting grid 20 and the shaking of the tank body 1 are utilized until the oxidation filtration of the industrial waste water is achieved. Then, the valve on the sewage pipe 3 is opened to discharge the filtered waste water.

[0030] When the activated carbon needs to be replaced regularly, the user first operates the second motor 22 to drive the screw rod 21 to rotate. The rotation of the screw rod 21 drives the supporting grille 20 to move upward, and the activated carbon on the supporting grille 20 slowly rises and eventually overflows from the discharge pipe 4 and is discharged. When the inactivated activated carbon is completely discharged, the second motor 22 is operated in the reverse direction to drive the supporting grille 20 to move downward until the supporting grille 20 fits with the limit block 23, and then the second motor 22 is turned off, and a certain amount of activated carbon is poured through the feed pipe 2 onto the supporting grille 20 laid in the tank body 1.
