Description
Technical Field
The utility model belongs to the technical field of the dust remover, concretely relates to bag collector top cap seal structure.
Background
The bag type dust collector is a dry type dust filtering device, is mainly used for collecting fine, dry and non-fibrous dust, and is widely applied to various industries such as steel, building materials, electric power and the like. Has the advantages of high dust removal efficiency, stable performance, easy dust recycling and the like. It is composed of leg part, ash bucket part, box body part, top cover part, back-blowing ash-cleaning device, air-intake (exhaust) smoke box, air-intake valve, air-exhaust valve and inclined ladder platform.
The working principle of the bag type dust collector equipment is as follows: the dust-containing smoke enters the dust hopper through the flow guide pipe after being expanded by the air inlet smoke box and then slowly rises to the filter chamber, and dust particles with larger particle sizes are settled in the dust hopper under the action of gravity because the sectional area of the airflow is suddenly enlarged and the flow speed is reduced. The dust particles with fine particle size pass through the outer surface of the filter bag and are trapped on the outer surface of the filter bag to form a dust cake layer under the comprehensive actions of inertia collision, screening, electrostatic attraction, hook-attaching effect and the like. The purified clean gas enters the air purifying chamber through the interior of the filter bag and is discharged by the exhaust smoke box.
The main functions of the top cover part of the bag-type dust collector include: (1) the interior of the equipment is isolated from the outside, so that the sealing effect is achieved, external air can be prevented from channeling into the interior, and rainwater can be drained to prevent the rainwater from permeating into the interior; (2) the equipment can be used as an overhaul platform when the filter bag and the framework are replaced.
The top cover part of the bag-type dust collector adopts a flat-top structure and comprises a top cover frame, a cover plate, a rubber sealing strip, a pressing plate, a fastening bolt and the like. The fastening bolt is welded in the top cover frame in advance, and during the use, detain the apron of embedded sealing strip on the top cover frame, sheathe in the clamp plate, screw up the nut with the spanner, can not only fix the apron and prevent its removal, with the tight pressure of sealing strip on the frame moreover, reach sealed effect. However, the existing structure of the top cover part is easy to cause the following problems in the long-term operation process: 1. the local sinking phenomenon occurs: the dust remover bears negative pressure load in the operation process, and the top cover is easy to partially sink and generate the phenomena of unevenness, so that air leakage (air is sucked into the equipment) is generated, and the negative pressure and the oxygen content of the system are influenced. When the rainfall is large, the local water seepage phenomenon is possible to occur; 2. the rubber sealing strip is easy to fall off: the rubber sealing strip is usually arranged in a circle of U-shaped sealing groove on the periphery of the back surface of the cover plate, but the phenomenon that the sealing strip falls off or falls off easily occurs when the cover plate is covered due to the fact that the U-shaped sealing groove is too wide or the rubber sealing strip is aged; 3. the pressure plate is not enough in rigidity and is easy to deform, so that the cover plate is not pressed tightly: the flat pressing plate made of thick steel plate is easy to deform due to insufficient rigidity, and the two ends of the flat pressing plate are tilted, so that the cover plate cannot be completely pressed, and the phenomenon of local air leakage occurs.
