Description

Open hopper with dust collection function

Technical Field

The utility model relates to a cement manufacture technical field specifically is an uncovered formula hopper from area gathers dust.

Background

At present, cement plant's material transfer chain in-process, the material generally gets into the feed bin earlier, then carry other positions that need this type of material through the lower part conveyer belt, for example, the emergent feed bin of the transportation of material and multiple material on the cement clinker grinding station etc., the transport flow generally uses forklift or overhead traveling crane to load into the material of fighting earlier to the feed bin, then just at the uniform velocity carry the production line through the belt feeder on, in order to ensure the continuous reliable operation of production line, but when the material was loaded into to the hopper, raise dust and fly ash are great, consequently, it is urgent to improve on-the-spot operational environment and become the problem of waiting to solve to restrain the material when getting into the feed bin through outside conveying mechanism.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem and providing a dust when can restrain the material and get into the feed bin open hopper from area gathering dust.

The utility model provides a problem, the technical scheme who adopts is:

the utility model provides a from uncovered formula hopper of taking gathering dust, includes casing, bag collector, and casing upper portion is double-deck shell structure, including interior casing and shell body, and the last port of interior casing is the feed inlet, and the lower port of shell body is the discharge gate, forms the crack that is used for absorbing raise dust and flying dust when the material whereabouts between interior casing and the shell body, and the crack department between shell body and the shell body is located in the setting of bag collector.

Adopt above-mentioned technical scheme the utility model discloses, compare with prior art, its outstanding characteristics are:

① the material has no fly ash and flying dust during blanking, thereby avoiding atmospheric pollution, and being safe and environment-friendly.

② has simple structure, easy production and manufacture, low cost, and convenient maintenance.

③ has wide application, high wear resistance and long service life.

Preferably, the present invention further provides:

the lower port of the inner shell is provided with a plurality of hammer sealing flap valves which are arranged in a grid shape, so that the materials can pass through and enter the lower part of the storage bin, and meanwhile, the valve plate is closed to prevent flying ash from overflowing when no material exists.

The bag type dust collector is of a modular structure and comprises a plurality of dust collecting modules which are uniformly arranged in a crack, and the number of the dust collecting modules can be increased or decreased according to needs.

The lower part of the outer shell is of an inverted cone structure.

And a plurality of dust suction holes are uniformly arranged on the side wall of the middle upper part of the inner shell and used for a bag type dust collector to absorb dust-containing gas at the inner upper part of the storage bin.

The dust suction hole is arranged in an upward inclined way towards the direction of the bag type dust collector.

The casing sets up on supporting platform, and the casing periphery is provided with stair and safety barrier.

Drawings

Fig. 1 is a schematic front view structure diagram of an embodiment of the present invention;

fig. 2 is a schematic top view of the embodiment of the present invention;

FIG. 3 is a schematic side view of an embodiment of the present invention;

in the figure: a bag-type dust collector 1; a dust collection module 1-1; an inner housing 2; an outer shell 3; the flap valve 4 is sealed by a heavy hammer; a feed port 5; a discharge port 6; a stock bin 7; a dust suction hole 8; a staircase 9; a safety barrier 10; a support platform 11; the nip 12.

The specific implementation mode is as follows:

the invention will be further described with reference to the following examples, which are intended only for better understanding of the invention and therefore do not limit the scope of the invention.

Referring to fig. 1, 2 and 3, an open hopper with dust collection function comprises a shell and a bag type dust collector 1, wherein the upper part of the shell is of a double-layer shell structure and comprises an inner shell 2 and an outer shell 3, the upper port of the inner shell 2 is a feed inlet 5, the lower port of the outer shell 3 is a discharge outlet 6, a crack 12 used for absorbing the dust and fly ash when the material falls is formed between the inner shell 2 and the outer shell 3, the bag type dust collector 1 is arranged at the crack 12 between the inner shell 2 and the outer shell 3, the double-layer shell structure is a double-layer shell structure, the crack 12 formed between the inner shell and the outer shell 3 can absorb the dust and fly ash when the material falls, and the material filtered by the bag type dust collector 1 slides into a feed bin 7.

The lower port department of interior casing 2 is provided with a plurality of hammer seal flap valves 4 that are latticed range, and the material is by in the interior sealed flap valve 4 of interior casing 2 through the weight advance lower part feed bin 7 in, lower part ash and dust can only get into in the crack 12 between interior casing 2 and the shell body 3 through bag dust collector 1 filtration owing to set up the reason of the sealed flap valve 4 of weight, set up the sealed flap valve 4 of weight and can guarantee that the material can pass through and advance feed bin 7 lower part, and the valve plate is closed when there is not the material simultaneously and is prevented the flying dust excessive.
