Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a device for treating fluorescent whitening agent production wastewater to prevent filter clogging. Background Technology

[0002] Fluorescent brightener production wastewater refers to the wastewater generated during the production of fluorescent brighteners. Fluorescent brighteners are chemical substances that can significantly improve the whiteness and gloss of items and are widely used in textiles, papermaking, coatings, detergents, and other fields. Their production process generates a large amount of wastewater, which is characterized by high concentration and difficulty in degradation, and contains various toxic and harmful substances such as aniline, DSD acid, and melamine.

[0003] Wastewater is generated during the production of fluorescent whitening agents. This wastewater needs to be filtered. The traditional method is to block the filter screen, but the screen will become clogged over time, resulting in a decrease in filtration efficiency. Regular manual cleaning is required, which is very troublesome. Therefore, there is a need for a wastewater treatment device for fluorescent whitening agent production that prevents the filter screen from clogging. Utility Model Content

A square cylinder is fixedly connected to the lower surface of the stirring drum. A drain pipe and an inlet bend are fixedly connected to the inner wall of the square cylinder. A sludge pump is fixedly connected to the surface of the square cylinder. A motor is fixedly connected to the upper surface of the stirring drum. A first inclined plate and a second inclined plate are fixedly connected to the inner wall of the stirring drum.

[0008] Furthermore, an L-shaped plate is fixedly connected to the upper surface of the stirring cylinder, and an additive cylinder is rotatably connected to the inner wall of the L-shaped plate. A flow hole is opened on the inner bottom wall of the additive cylinder. The lower surface of the additive cylinder is rotatably connected to the upper surface of the second friction wheel. A first O-ring is fixedly connected to the upper surface of the second friction wheel, and a second O-ring is fixedly connected to the lower surface of the second friction wheel. The surface of the first O-ring is in pressure contact with the lower surface of the additive cylinder, and the surface of the second O-ring is in pressure contact with the upper surface of the baffle.

[0009] Preferably, the sludge pump is equipped with a sludge suction pipe at its inlet end, a sludge collection trough is formed on the surface of the first inclined plate, and a plurality of through holes are formed on the surface of the sludge suction pipe, with the surface of the sludge suction pipe in contact with the inner wall of the sludge collection trough.

[0010] Furthermore, the output end of the motor passes through the inner top wall of the mixing drum and is fixedly connected to a mixing shaft, a baffle plate is fixedly connected to the surface of the second inclined plate, and a controller is fixedly connected to the surface of the square cylinder.

[0012] The beneficial effects of this utility model are as follows:

[0013] During the rotation of the stirring shaft, the first friction wheel is driven to rotate. The first friction wheel rubs against the second friction wheel, driving the second friction wheel to rotate. When the position of the water outlet corresponds to the position of the liquid flow hole, the chemical reagent in the additive cylinder flows into the stirring drum through the water outlet, mixes with the fluorescent whitening liquid in the stirring drum, and causes a chemical reaction and precipitation. After precipitation, the impurity particles are deposited in the sludge collection tank under the guidance of the first and second inclined plates. The solid impurities in the sludge collection tank are sucked out by the sludge pump, effectively preventing the filter screen from becoming clogged after long-term use. Attached Figure Description
