A chemical waste liquid anti-blocking treatment device

Abstract

The invention discloses an anti-blocking treatment device for chemical waste liquid, which comprises a tank body, the upper side wall of the tank body is connected with a water inlet pipe, and a valve is installed on the water inlet pipe, and the lower side wall of the tank body passes through a soft The tube is connected with a diversion tube, the tank is rotatably connected with a filter screen, the lower side of the tank is provided with a support tube, and the lower side wall of the tank is fixedly connected with a lifting rod inserted in the support tube. A return spring is fixedly connected between the lower end of the lift rod and the inner bottom wall of the support tube, a pressing rod is fixedly connected to the outer wall of the lift rod, and a horizontal horizontal plate is fixedly connected to the outer wall of the support tube. The present invention stops the discharge of water when there are too many impurities on the filter screen and rotates the filter screen to clean the filter screen impurities, and switches the filter core through the rotation of the connecting pipe when the filter core is blocked, ensuring the normal flow of waste water in the diversion tube , to ensure the normal treatment of subsequent waste liquid.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to an anti-blocking processing device for chemical waste liquid. Background technique [0002] Chemical wastewater is the process wastewater, cooling water, exhaust gas washing water, equipment and site washing water and other wastewater discharged in chemical production. Wastewater has changed its original physical or chemical properties in the process of use. It contains different types of impurities. If it is discharged without treatment, it will cause different properties and different degrees of pollution of the water body, thereby endangering human health and affecting industry and agriculture. production. [0003] At present, coagulation treatment is required in the treatment of wastewater. The impurities in the wastewater are precipitated by mixing the coagulant with the wastewater, and the precipitated impurities are filtered through the filter screen, and the wa...

Wastewater has changed its original physical or chemical properties in the process of use. It contains different types of impurities. If it is discharged without treatment, it will cause different properties and different degrees of pollution of the water body, thereby endangering human health and affecting industry and agriculture. production

[0003] At present, coagulation treatment is required in the treatment of wastewater. The impurities in the wastewater are precipitated by mixing the coagulant with the wastewater, and the precipitated impurities are filtered through the filter screen, and the wastewater after the preliminary treatment is discharged. However, the traditional sewage The sediment filtered by the treatment device accumulates in the device, which will easily affect the filtering effect of the filter screen or filter element, thereby affecting the treatment of waste liquid
