Embodiment 1

[0040] This scheme includes two sets of dust removal devices arranged symmetrically to the center line of the locomotive track on both sides of the track. The two top suction dust removal devices can be arranged in a mirrored combination with the center line of the locomotive track as the axis line. The top suction dust removal device is connected to the pipeline inspection door. The access door includes a door frame, a flange, a door handle, and nuts and bolts. The dust removal device includes a top suction cover 4, which is a long air outlet top suction type. The top suction cover 4 is an inverted triangle steel structure, and the upper part is a dust suction The top suction hood 4 is an arc-shaped flat steel structure protruding from the middle to the outside along the vertical direction. The projecting range here is guaranteed to be within the scope of the entire dust removal device. The bottom of the top suction hood 4 and the discharge port along the track The pipeline 5 a...

Embodiment 2

[0046] Example 2 On the basis of Example 1, the seal of the high-position silo discharge valve 1 was redesigned. Under the condition of keeping the discharge unblocked, a top sealing plate 2 and a top sealing plate 2 and The enclosure 3 around the discharge valve 1, the sealing plate 2 between the upper silo and the platform of the discharge port platform below; minimize the possibility of material divergence; the top sealing plate 2 surrounds the periphery of the lower port of the silo The set steel structure plate, the top sealing plate 2 includes: the lower port of the silo and the outer steel structure of the lower port of the silo. One solves the need for rooting of the steel structure around the silo discharge valve 1; the other solves the problem of achieving the vertical change from the open type to the closed type above the platform of the silo discharge valve 1 during the dusty gas capture period. The purpose of silo discharge valve 1 above the platform to induce wind...

Embodiment 3

[0048] Example 3 On the basis of Example 1 or 2, the two sides of the outer track of the low-level transfer station are arranged in parallel with a closed enclosure structure using the combination of the upper lighting belt 10 and the lower color steel plate 11, the upper lighting belt 10 and the lower color steel plate 11 Respectively adopt the light structure of (lighting belt + thin steel plate) steel frame; for the clearance between the closed envelope structure of the lighting belt 10 and the lower color steel plate 11 and the existing transfer station, supplemented by flexible materials to strengthen the sealing effect . The flexible material here can be soft. The purpose of adding the daylighting belt 10 and the windshield wall of the lower color steel plate 11 includes: one is to solve the large influence factor of the low-level container blanking to withstand the lateral wind during the dusty gas capture; the other is to take into account the factors of the daylighting...

Abstract

The invention discloses a dust removal device for dusty gas generated during discharging of a transfer station material bin, and belongs to the field of dust removal system equipment. According to theproblems that in the prior art, due to insufficient space, arrangement of dust removal devices is difficult, the open area of a transfer station is prone to being influenced by surrounding transversewind, consequently, dust and smoke are diffused, timely observation and material level leveling work of workers cannot be ensured, and normal production is influenced, lateral top suction hoods are adopted and arranged on the two sides and are strewn at random for top suction and downward drawing, whole top suction dust removal devices are connected with transfer station stand columns through profile steel structures of light steel structures, and overall frame structures are formed by the top suction dust removal devices, material bins at high positions, the transfer station stand columns atlow positions and supporting legs additionally arranged on operation platforms correspondingly. According to the dust removal device, the efficient dust removal effect can be achieved, the structureis simple, demounting is convenient, the labor intensity is reduced, and normal production work of a locomotive container is not influenced.

Description

Technical field [0001] The invention relates to the field of dust removal system equipment, and more specifically, to a dust removal device for discharging dust-containing gas in a silo of a transfer station. Background technique [0002] The dust-laden gas top suction dust removal device for the silo discharge of the transfer station is a supporting device of the coke product dust removal system. For the coke transfer station that serves as a storage buffer between two blast furnaces, the transfer station silo discharges dusty gas top suction The dust removal device is through the cover top and the concrete platform at the lower end of the transfer station silo, that is, the transfer station silo discharge and dust removal adopts the method of strong dust collection in the silo discharge area, that is, the width and length characteristics of the transfer station The bin unloading area is effectively enclosed. A top suction hood is installed above the side of the airspace between...
