Abstract
The invention relates to a door sealing structure and method for a special dusting machine for dust. The door sealing structure and method not only can prevent seal strips used for sealing the four corners of a door from rapidly ageing and fracturing, but also can eliminate noise on the premise of reliable sealing. The door sealing structure comprises the vertical type dusting machine for the dust. Door leaf four corners of an upper inspection door in the vertical type dusting machine for the dust are matched with the four corners of a door frame to form four arc-shaped corners. Door leaf corners of a middle inspection door in the vertical type dusting machine for the dust are matched with the four corners of a door frame to form four arc-shaped corners. Door leaf corners of a lower inspection door in the vertical type dusting machine for the dust are matched with the four corners of a door frame to form four arc-shaped corners. The door leaf corners of the upper inspection door and the four arc-shaped corners of the door frame are sealed through the arc-shaped seal strips, the door leaf corners of the middle inspection door and the four arc-shaped corners of the door frame are sealed through the arc-shaped seal strips, and the door leaf corners of the lower inspection door and the four arc-shaped corners of the door frame are sealed through the arc-shaped seal strips. The sealing structure and method have the advantages that the problems that in the background technology, because seal strips between the upper inspection door, the middle inspection door and the lower inspection door and the door frames are bent, stress is concentrated, and ageing and fracturing are prone to happen are solved; because the hollow seal strips are adopted for sealing between the upper inspection door, the middle inspection door and the lower inspection door and the door frames, sealing reliability is high, and noise which is possibly generated between the upper inspection door, the middle inspection door and the lower inspection door and the door frames is fundamentally eliminated.
Description
Technical field
The present invention relates to one and can either avoid four jiaos of weather strip quick aging be full of cracks of hermatic door, again can be under the prerequisite that realizes positiver sealing, the special dust removal machine door sealing structure of dust and the encapsulating method that abate the noise, belong to the special dust removal machine seal assembly of dust and manufacture field.
Background technology
Existing vertical dust dedusting gate is in structure design, and four jiaos of door is right angle with four jiaos of doorframe, and adopts weather strip to seal.Its weak point: four jiaos of door is that right-angle design must cause weather strip for sealing at four jiaos of place's knuckles with four jiaos of doorframe, and its knuckle causes the hard power of weather strip concentrated, not only affects sealing performance, and aging cracking very easily.
Summary of the invention
Purpose of design: exempt to keep away the weak point in background technology, design one can either be avoided four jiaos of weather strip quick aging be full of cracks of hermatic door, again can be under the prerequisite that realizes positiver sealing, the special dust removal machine door sealing structure of dust and the encapsulating method that abate the noise.
Design scheme: in order to realize above-mentioned purpose of design.1, in vertical dust dust removal machine, four jiaos between upper access door, middle access door and four jiaos of lower access door door leafs and doorframe are four jiaos of arcs and the design that adopts the sealing of arc weather strip, are one of technical characterictics of the present invention.The object of design is like this: four jiaos of upper access door, middle access door and lower access door door leafs adopt four jiaos of arcs, it can fundamentally solve for seal weather strip between four jiaos, four jiaos of door leafs and doorframe because the stress that right-angle bending causes sealing performance concentrated, that forced sealing brings is uncertain, the easy aging cracking of weather strip, the poor defect of noise reduction.2, arc weather strip is the design of hollow vapour-pressure type weather strip, is two of technical characterictic of the present invention.The object of design is like this: because hollow sealing strip has the function of inflating and exitting, when it is when sealing the sealing of upper access door door leaf, access door door leaf and lower access door door leaf and doorframe, as long as inflate, can realize after hollow sealing strip inflation the positiver sealing of upper access door door leaf, middle access door door leaf and lower access door door leaf and doorframe by the single direction inflating valve on hollow sealing strip; In the time that needs unload upper access door door leaf, middle access door door leaf and lower access door door leaf, as long as Aerating needle is inserted in the single direction inflating valve on hollow sealing strip and gas discharge, hollow sealing strip in hollow pneumatic seal can be become to flat, maintenance door leaf conveniently takes off.
Technical scheme 1: a kind of vertical dust dust removal machine door sealing structure, comprise vertical dust dust removal machine, four jiaos between four jiaos of upper access door in described vertical dust dust removal machine, middle access door and lower access door door leafs and doorframe coordinate for four jiaos of arcs, and four jiaos of arcs between upper access door, middle access door and four jiaos of lower access door door leaf arcs and doorframe adopt arc weather strips to seal.
Technical scheme 2: a kind of vertical dust dust removal machine door sealing structure encapsulating method, in vertical dust dust removal machine, upper access door, middle access door and lower access door door leaf are greater than between doorframe or upper access door, middle access door and lower access door door leaf and doorframe and are matched in clearance, being arcuate structure by four jiaos, hollow vapour-pressure type weather strip is placed between upper access door, access door and lower access door and doorframe, then by the unidirectional valve nozzle injecting gas on hollow vapour-pressure type weather strip, hollow vapour-pressure type weather strip will be sealed between upper access door, middle access door and lower access door and doorframe.
The present invention compared with background technology, the one, solved that the stress that between upper access door, middle access door and lower access door and the doorframe that background technology exists, weather strip bending causes is concentrated, the easily generation of aging cracking phenomenon; The 2nd, between upper access door, middle access door and lower access door and doorframe, adopt hollow sealing strip sealing, not only the reliability of sealing is high, and do not produce that stress is concentrated, easy aging cracking, the more important thing is owing to sealing by gasbag-type hollow sealing strip between upper access door, middle access door and lower access door and doorframe, fundamentally eliminated issuable noise between upper access door, middle access door and lower access door and doorframe.
