Description

Dust suppression bucket

Technical Field

The utility model belongs to the field of material transportation, and particularly relates to a dust suppression bucket.

Background

During the material transporting, loading and unloading process, the bulk grains, oil and bean pulp are transported in warehouse, and the material moves downwards from the blanking port in high speed. The high-speed air flow extruded by the material under the shearing action of the moving material and the air brings dust to fly around, and a large amount of dust is generated and is diffused into the surrounding environment when the blanking impacts the ground due to the large fall of the material. The control of dust is critical to the safety, environment and health of a grain and oil processing plant, and the dust generated by a grain and oil processing plant warehouse belongs to tiny dust, and the particle size of the dust is less than 10 microns. The dust particles have smaller mass and slower sedimentation speed, so that the sedimentation lasts for a period of time, and the smaller particle size is in a floating state for a long time. The grains in the grain dust are inflammable substances, the dust has potential explosion hazard, is harmful to the health of operators, pollutes the atmosphere environment, and simultaneously, a large amount of dust is escaped to cause the economic loss of grain and oil factories.

The utility model discloses a dust suppression hopper, and a specific implementation mode of the utility model is further described below with reference to a preferred embodiment.

Preferred embodiments.

The embodiment provides a dust suppression bucket, which comprises a supporting frame 200, the upper end of support frame 200 is equipped with upper hopper 100, the below of support frame 200 is equipped with down hopper 300, down hopper 300 pass through telescopic spring 500 with support frame 200 is connected, the lower extreme of upper hopper 100 is equipped with first discharge gate, first discharge gate corresponds the top of lower hopper 300, be equipped with the case in the lower hopper 300, the middle part of case is equipped with support axostylus axostyle 400, the upper end of support axostylus axostyle 400 is fixed and is equipped with dead lever 430, dead lever 430 with support frame 200 fixed connection, the lower extreme of lower hopper 300 is equipped with second discharge gate 310, the case with second discharge gate 310 assorted.

When a certain weight is reached after the material enters the hopper 300, the extension spring 500 is extended, and the hopper 300 is lowered relative to the valve core fixed at the center. A ring is opened between the hopper 300 and the spool to allow the discharge of material. Material will remain flowing only when there is sufficient material in the hopper 300 to cause the extension of the extension spring 500. Otherwise, the ring will close. In actual operation, the hopper 300 is gently oscillated up and down to discharge material due to the fluctuation of the force balance between the telescopic spring 500 and the weight of the material, which is nonlinear.

Different from the common telescopic corrugated pipe, the dust suppression hopper is directly arranged at the unloading point and is hung above a certain height of receiving equipment and a place, such as a container truck. This height remains constant throughout the discharge process, except for the up and down fluctuation of the hopper 300. Thus, most of the complexity associated with bellows design is eliminated. The dust suppression hopper has no internal moving parts and does not require any tools for operation.

The dust hopper operation of the present utility model results in a dense material discharge pattern with little air in the nearly solid stream. Natural agitation and settling from the hopper 300 results in limited air release as material enters the hopper 300. Then, since the material is expelled from the ring pushed under the relative pressure of the extension spring 500, it undergoes a further 'squeezing' action. As a result, a "dense" mass flow can tolerate a relatively high level, any dust being carried away during the fall and dragged into the column, and the dust emissions being minimal when the mass reaches the ground.

Further, the second discharge port 310 is in a truncated cone shape with a gradually reduced cross-sectional area, the valve core includes a first cone and a second cone 410, the bottom surface of the first cone coincides with the bottom surface of the second cone 410, the first cone is disposed at the lower end of the second cone 410, and the second cone 410 is matched with the second discharge port 310. When the materials in the discharging hopper 300 are proper, the telescopic spring 500 can tighten the discharging hopper 300, so that the upper end of the second cone 410 is attached to the inner wall of the discharging hopper 300, the materials can not fall down, when the materials are more, the discharging hopper 300 moves down, a gap with a circular ring structure is formed between the second cone 410 and the discharging hopper 300, and the materials in the discharging hopper 300 can flow out through the gap.

Further, the included angle between the side wall of the second cone 410 and the central axis of the second cone 410 is A1, the included angle between the side wall of the second discharge port 310 and the central axis of the second discharge port 310 is A2, and the A2< A1 can ensure that the material in the discharging hopper 300 can flow out from the gap between the valve core and the discharging hopper 300.

Further, a first hook 510 is arranged at the upper end of the telescopic spring 500, a plurality of screws 550 are arranged on the supporting frame 200, a first hanging ring 551 is hinged to the lower end of each screw 550, the first hook 510 is matched with the first hanging ring 551, a second hook 520 is arranged at the lower end of the telescopic spring 500, a plurality of lifting lugs 320 are arranged at the lower end of the discharging hopper 300, a second hanging ring 321 is hinged to each lifting lug 320, and the second hook 520 is matched with the second hanging ring 321. The first hook 510 is hung in the first hanging ring 551, the second hook 520 is hung in the second hanging ring 321, when the materials in the discharging hopper 300 are enough, the telescopic spring 500 is stretched, the discharging hopper 300 moves downwards, a gap with a circular ring structure is formed between the valve core and the discharging hopper 300, and the materials in the discharging hopper 300 can flow out through the gap.

Further, a plurality of support rods 530 are fixedly arranged at the lower end of the support frame 200, a plurality of rollers 540 are arranged on the support rods 530, and the rollers 540 are correspondingly arranged between the support rods 530 and the discharging hopper 300. The roller 540 is in rolling connection with the discharging hopper 300 in multiple directions, so that the discharging hopper 300 is ensured to be vertical and does not shake transversely.

Further, a connection ring 440 is disposed below the support frame 200, the connection ring 440 is sleeved on the outer side of the support rod 530, and the connection ring 440 is fixedly connected with the support rod 530. The connecting ring 440 fixedly connects the lower ends of the support rods 530 together, thereby enhancing the stability of the support rods 530, and further ensuring the stability of the discharging hopper 300 during lifting without transverse shaking.
