The dust removal system, the mixing station and the dust removal control method of the proportioning bin of the invention are described below with reference to fig. 1 to 9.

This embodiment provides a dust pelletizing system of proportioning bin 1 for proportioning bin 1, wherein one side of proportioning bin 1 is equipped with the entry. Referring to fig. 1, during production, sand and stone materials of various specifications are respectively shoveled into a proportioning bin 1 by a proportioning transportation device such as a loader 2, are proportioned, fall onto a belt conveyor 5 through a feeding hopper 4, and are conveyed to the next link by the belt conveyor 5. When the loader 2 is used for batching, a large amount of dust can be generated in the walking process and the falling process of the sand and stone materials of the loader 2, so that the operation environment and the atmospheric environment quality are seriously influenced, and the physical health of workers is greatly damaged.

Referring to fig. 2, the dust removing system provided in this embodiment includes: a dust hood 6, a dust remover 3, a blast hood assembly and a wind curtain mechanism 12. The dust hood 6 is arranged inside the proportioning bin 1 and at least positioned on one side of the proportioning bin 1 opposite to the inlet. I.e. the dust hood 6 can be provided at least on the side opposite the inlet to enable better suction of fugitive dust. The dust hood 6 may be located at the top, middle upper part or middle part of the proportioning bin 1, and is not limited in particular. The outlet of the dust hood 6 is connected with the inlet of the dust remover 3. The outlet of the dust hood 6 can be communicated with the inlet of the dust remover 3 through the air inlet pipeline 7, and when the dust remover 3 is opened, negative pressure is formed in the air inlet pipeline 7, so that the dust absorption effect of the dust hood 6 is realized.

The blast hood subassembly is established inside the proportioning bins 1 and being located proportioning bins 1 is close to one side of entry, the blast hood subassembly orientation dust hood 6 sets up, is used for blowing the air current to dust hood 6. The blast hood subassembly is used for blowing to 1 inside of proportioning bins, establishes in the one side relative with suction hood 6 for the air-out of blast hood subassembly is blown to suction hood 6, is favorable to forming the air current towards suction hood 6 in 1 inside of proportioning bins, does benefit to the suction of suction hood 6 to the raise dust.

The air curtain mechanism 12 is arranged outside the proportioning bin 1 and faces the inlet; i.e. the air curtain mechanism 12 is arranged outside the dosing bin 1 at the inlet. And the air curtain mechanism 12 is movable between a position near the inlet and a position away from the inlet. The air curtain mechanism 12 is provided as a movable structure, the air curtain mechanism 12 can be initially located at a position far away from the inlet, namely, a distance can exist between the initial position and the inlet, and the air curtain mechanism 12 can move back and forth between the initial position and a position close to the inlet. The air curtain 12 is intended to move from away from the inlet towards the inlet when the ingredient conveying device is driven towards the ingredient silo 1 and/or away from the ingredient silo 1.

Specifically, the loader 2 drives to the proportioning bin 1, that is, the loader 2 moves to the inlet of the proportioning bin 1, and the process of unloading the inside of the proportioning bin 1 is performed; the loader 2 leaves the proportioning bin 1, namely the loader 2 gradually leaves the inlet of the proportioning bin 1 after the unloading is finished. The air curtain mechanism 12 may form an air curtain outside the inlet of the batching plant 1 to prevent the space between the air curtain and the inlet and the dust inside the batching plant 1 from escaping. This embodiment sets up air curtain mechanism 12 and is movable structure, and proposes when loader 2 enters the mouth and removes towards proportioning bins 1, and air curtain mechanism 12 moves towards the entry, and not only the accessible forms the air curtain and plays the effect that prevents the raise dust and spill over, and along with the removal of air curtain mechanism 12, still can blow the raise dust that produces on the loader 2 movement path to proportioning bins 1 inside through the air curtain gradually, is favorable to realizing the absorption to this part raise dust.

Similarly, when loader 2 leaves proportioning bins 1 and drives away from the entry promptly, air curtain mechanism 12 can follow initial position and move towards the entry equally, not only plays the effect that prevents the raise dust and spill over through forming the air curtain, and along with air curtain mechanism 12's removal, still can blow the raise dust that produces on loader 2 moving path to proportioning bins 1 inside through the air curtain gradually, is favorable to realizing the absorption to this part raise dust.

According to the dust removal system for the proportioning bins, the blast hood assembly is arranged inside the proportioning bin 1 and matched with the dust hood 6, so that an airflow field blowing towards the dust hood 6 can be formed inside the proportioning bin 1, the dust collection effect of the dust hood 6 can be improved, and raised dust can be effectively sucked; the air curtain mechanism 12 is arranged outside the inlet of the proportioning bin 1, the effect of preventing the flying dust from overflowing can be achieved by forming an air curtain, and the air curtain mechanism 12 is arranged to be a movable structure, so that when the loader 2 drives in and out, the flying dust generated on the moving path of the loader 2 can be blown into the proportioning bin 1 through the air curtain by the movement of the air curtain mechanism 12, and the suction of the flying dust is favorably realized; this dust pelletizing system is favorable to realizing the effective absorption to raise dust on 1 inside and the entrance loader 2 removal route of proportioning bins, and is favorable to improving the absorption effect, improves the control efficiency to gaseous pollutants, raise dust concentration when effectively reducing the material loading.

Further, the wind direction of the wind curtain mechanism 12 may be inclined toward the inlet of the surge bin 1.
