At the same time, the activated carbon powder escapes into the air through the pipe opening of the dissolving tank 6, causing environmental pollution. Operators who are exposed to the polluted environment for a long time may suffer from occupational diseases and affect their physical and mental health. Utility Model Content

[0023] Example 1: Reference Figure 2This utility model discloses a dust prevention device for an activated carbon dissolving tank, comprising an activated carbon silo 1, a screw conveyor 2, a pneumatic butterfly valve 3, a clamp 4, a flexible connecting pipe 5, a dissolving tank 6, a stirrer 7, and an ultrasonic level gauge 8. The activated carbon silo 1 is installed on the screw conveyor 2, the pneumatic butterfly valve 3 is installed on the discharge pipe of the screw conveyor 2, the top end of the flexible connecting pipe 5 is connected to the discharge pipe through the clamp 4, the stirrer 7 and the ultrasonic level gauge 8 are installed on the dissolving tank 6, and also includes a dust prevention device 9, the discharge port of the flexible connecting pipe 5 is connected to the dust prevention device 9, and the dust prevention device 9 is installed on the dissolving tank 6.

[0024] Reference Figure 3 The dustproof device 9 includes a housing 91 and a vortex bucket 92. The housing 91 has a cavity that runs vertically through it, and the vortex bucket 92 is installed in the cavity. The top inlet of the housing 91 is connected to the outlet of the flexible connecting pipe 5, and the bottom outlet of the housing 91 is detachably fixed to the dissolving tank 6 and communicates with the inside of the dissolving tank 6. The side wall of the housing 91 is connected to a main water inlet pipe 93 that communicates with the cavity, and the side wall of the vortex bucket 92 is connected to a vortex bucket inlet pipe 94 that communicates with its interior.

[0025] Reference Figure 5 The vortex bucket inlet pipe 94 includes a main pipe 941 and a secondary pipe 942. The outlet end of the main pipe 941 extends through the outer shell 91 and the vortex bucket 92 into the interior of the vortex bucket 92. One end of the secondary pipe 942 is connected to the main pipe 941, and the outlet end of the other end extends through the outer shell 91 and the vortex bucket 92 into the interior of the vortex bucket 92. The outlet ends of the main pipe 941 and the secondary pipe 942 are symmetrically arranged about the central axis of the vortex bucket 92.

[0026] Reference Figure 4 The cyclone bucket 92 has a conical structure with a cone angle ranging from 50° to 70°. An overflow channel 95 is formed between the top of the cyclone bucket 92 and the inner wall of the outer shell 91, with a gap ≥ 50mm. Mounting flanges 96 are fixedly connected to the bottom of the outer shell 91 around its perimeter, allowing the outer shell 91 to be detachably fixed to the dissolving tank 6 via these flanges.

The source water enters the vortex bucket 92 through the outlet of the main pipe 941 and the outlet of the secondary pipe 942, where it rotates and flows. At the same time, activated carbon powder falls in through the powder inlet 921 and undergoes preliminary mixing in the vortex bucket 92. Then, it is injected into the dissolving tank through the outlet at the mounting flange 96. During this process, if the water volume is too large or the activated carbon powder is excessive, the mixture can overflow into the dissolving tank through the overflow channel 95 above the vortex bucket 92, preventing the solution from escaping from the powder inlet 921.

[0028] The implementation principle of this utility model is as follows: This utility model discloses a dust prevention device for an activated carbon dissolving tank. Through a swirling bucket 92 and a dual-inlet design, the activated carbon is initially mixed in the swirling water before being injected into the dissolving tank, thus suppressing dust dispersion at the source. An overflow channel 95 prevents solution backflow, ensuring accurate liquid level detection and a safe working environment.
