Both pipelines are vertically downward, and solenoid valves are arranged on both pipelines. A number of anti-caking spheres are arranged inside the anti-caking ball storage tank, and the diameter of the anti-caking spheres is smaller than the inner diameter of the pipeline.

[0009] Preferably, an electric heating layer is arranged on the inner wall of the activated carbon storage tank. A powder conveying pump is arranged on one side of the activated carbon storage tank. The output end and the input end of the powder conveying pump are respectively communicated with the upper and lower sides of the activated carbon storage tank through pipelines. A moisture-absorbing cotton is arranged above the inside of the activated carbon storage tank.

[0010] Preferably, both the activated carbon storage tank and the anti-caking ball storage tank include a tank body and a cover body, and the cover body is connected to the corresponding tank body by bolts.

[0012] Preferably, a vibration motor is arranged on one side of the anti-caking ball storage tank.

[0013] Preferably, the anti-caking spheres are porcelain balls.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] In the present utility model, by arranging the anti-caking ball storage tank, when the powdered activated carbon is fed from the activated carbon storage tank into the chain bucket elevator, anti-caking spheres can be fed into the chain bucket elevator through the anti-caking ball storage tank.

A number of anti-caking spheres 5 are arranged inside the anti-caking ball storage tank 2, and the ball diameter of the anti-caking spheres 5 is smaller than the inner diameter of the pipeline.

[0022] When this device is in use, when the powdered activated carbon is fed from the activated carbon storage tank 1 into the chain bucket elevator 3, the anti-caking spheres 5 can be fed from the anti-caking ball storage tank 2 into the chain bucket elevator 3. The anti-caking spheres 5 collide and mix with the powdered activated carbon in the horizontal conveying part of the chain bucket elevator 3, which can effectively avoid the caking of the powdered activated carbon, effectively ensure the integrity of the activated carbon transportation and the normal progress of subsequent processes, and the use effect is excellent.

[0023] Embodiment 2

[0024] As Figure 2 shown, the difference between this embodiment and Embodiment 1 is that:

[0025] In this embodiment, an electric heating layer 6 is arranged on the inner wall of the activated carbon storage tank 1. A powder conveying pump 7 is arranged on one side of the activated carbon storage tank 1. The output end and the input end of the powder conveying pump 7 are respectively communicated with the upper and lower sides of the activated carbon storage tank 1 through pipelines. The electric heating layer 6 is a copper layer with a cavity, and electric heating wires are arranged inside. The activated carbon in the activated carbon storage tank 1 can be pumped out through the powder conveying pump 7, so that the activated carbon can continuously move in the activated carbon storage tank 1 before being fed into the chain bucket elevator 3, and drying can be realized in cooperation with the electric heating wires to avoid moisture.

[0026] In this embodiment, both the activated carbon storage tank 1 and the anti-caking ball storage tank 2 include a tank body 8 and a cover body 9. The cover body 9 is connected to the corresponding tank body 8 by bolts. The separation of the cover body 9 from the tank body 8 facilitates the addition of anti-caking balls 5 or powdered activated carbon into the tank body 8.

[0027] In this embodiment, a rotary drive motor 10 is provided at the top of the cover body 9 of the activated carbon storage tank 1. The drive end of the rotary drive motor 10 penetrates the cover body 9 and is equipped with a stirring structure 11. The stirring structure 11 (the stirring mechanism is composed of several stirring rods) can be rotated by the rotary drive motor 10, further promoting the movement of the activated carbon in the activated carbon storage tank 1 and making it evenly heated. On the one hand, the activated carbon can be preheated to facilitate the subsequent regeneration process. At the same time, the activated carbon can be dried (a moisture-absorbing cotton 17 is provided above the inner part of the tank body 8 of the activated carbon storage tank 1 to absorb water vapor and keep the tank body 8 in a closed state to prevent powder from escaping). It should be noted here that a pressure relief hole is provided on the cover body 9 (not shown in the figure to avoid pressure changes in the tank body 8 caused by heating).

[0028] In this embodiment, a vibration motor 14 is provided on one side of the anti-caking ball storage tank 2. The vibration of the vibration motor 14 is beneficial for the anti-caking balls 5 to enter the bucket elevator 3.

[0029] In this embodiment, the anti-caking balls 5 are porcelain balls.
