Abstract
The utility model provides a double zipper type moving sealing device which is composed of an opening main duct (1), a movable ventilating opening (2), a movable sealing strip (3), a convex pressing wheel (4), a guiding wheel (5), a concave pressing wheel (6), an inner pressing wheel (7) and a wedge-shaped block (8). Movable integration is composed of the movable ventilating opening which is supported by the guiding wheel shaft, the convex and concave pressing wheels, the inner pressing wheel and the wedge-shaped block. A guide track on the opening part of the opening main duct is in bidirectional walking. The movable sealing strip bypasses the elbow of the ventilating opening to make the ventilating opening communicated with the main duct. The rest of the opening of the main duct is sealed. The utility model has the advantages that the ventilating system composed of the device can thoroughly solve the problem that the northern railway carriage preparing library has serious smoke pollution and does not influence the temperature in the library.
Description
The utility model belongs to the HVAC technical field.
Now the northern area of China passenger train is reorganized and outfit the storehouse working environment and is had serious smoke contamination problem winter, independent greenhouse, the drinking water boiler chimney of every joint passenger vehicle are primary pollution source, domesticly be a lot of ways of head it off, as electrostatic precipitator, thermostatic air exchanger etc., but it is not thorough, pollute because flue dust has formed in the storehouse, and energy consumption is bigger, what have also can influence storehouse temperature.
The utility model is exactly for solving a kind of double slide fastener formula moving sealing device that an above-mentioned difficult problem designs, and this device makes packaged type ventilated port two-way moving on the guide rail of main pipe opening, and can not influence the sealing of main pipe.The utility model is added advanced control system and rational additional device, as exhaust fume collecting hood etc., can realize the automatic contraposition to the passenger vehicle chimney, and flue dust is focused on and discharges, thorough head it off, and can not influence storehouse temperature.
This device comprises open type main pipe (1); Packaged type ventilated port (2); Sealing strip (3) alive; Convex guide pulley (4); Upper saw pulley (5); Spill guide pulley (6); Interior guide pulley (7); Wedge shape chunk (8); The portable seal arrangement of common composition.Supporting the packaged type ventilated port by upper saw pulley, and with protruding, recessed guide pulley and in guide pulley, wedge shape chunk etc. form one movably whole, two-way moving on the guide rail of open type main pipe opening, the sealing strip of living is walked around the packaged type ventilated port, and the remaining part of pipeline tapping is sealed, the packaged type ventilated port is communicated with main pipe, and flue dust enters the packaged type ventilated port by exhaust fume collecting hood by arm, focuses on discharging by the open type main pipe then.
Its advantage is that the packaged type ventilated port can two-way long distance move on the guide rail of main pipe opening, and can not influence the sealing of main pipe in moving process.Fume extractor with its assembling can thoroughly solve smoke contamination problem in the coach servicing shed, and does not influence storehouse temperature, and energy consumption is few.

Accompanying drawings is as follows: this device has open type main pipe (1), angle steel or other stiffening device are arranged as guide rail on the both sides of its opening portion, head is moved thereon, opening portion has other movable sealing device sealing such as sealing strip alive or venetian blinds, open type main pipe one end links to each other with soot processing device, the other end sealing; Packaged type ventilated port (2) is a dihedral, the sealing strip of being convenient to live is walked around from its bottom, and the bottom has flange plate to link to each other with arm, and top has the movable sealing device to seal with the open type main pipe around the packaged type ventilated port, and be connected with upper saw pulley (5), described upper saw pulley is made the train wheel shape; The sealing strip (3) of living is made by flame-retardant elastomer, its top has the interrupted uniform interior hook of two rows to hook the guide rail of main pipe, to support sealing strip alive, both sides respectively have a projection and guide rail bottom to be close to the gap between the sealing hook rail, and the two ends of the sealing strip of living are fixed on the main pipe; Convex guide pulley (4) is a convex, is hooked in the guide rail in the sealing strip of being convenient to live and opens, and play the effect of supporting sealing strip, and the convex guide pulley links to each other with upper saw pulley; It is for cooperating interior guide pulley with the sealing strip bending, making its turnover guide rail easy that spill guide pulley (6) is done concavity; Interior guide pulley (7) is made convex and is made sealing strip bending alive for cooperating recessed guide pulley; Wedge shape chunk (8) is done wedgewise, and hook backs down in the sealing strip in order living, and makes its getaway and sagging.The packaged type ventilated port is housed on the upper saw pulley, the bilateral symmetry of packaged type ventilated port movement direction is equipped with protruding guide pulley, recessed guide pulley, interior guide pulley and a pair of wedge shape chunk, their common compositions one are movably whole, two-way moving on the guide rail of main pipe opening, its working procedure is: when the packaged type ventilated port moves right, to the live interior hook of sealing strip of a pair of wedge shape chunk that right inner side links to each other with the packaged type ventilated port backs down, make sealing strip alive sagging naturally, and walk around from packaged type ventilated port bottom by guide pulley in right and the guiding of recessed guide pulley, recessed guide pulley in left side and interior guide pulley are pressed into spill with sealing strip earlier, be convenient to the sealing strip of living is pressed into the main pipe opening portion by the protruding guide pulley of back, after the sealing strip of living is pressed into opening portion, the interior hook of the sealing strip of living supports sealing strip alive owing to elastic reaction opens, and the projection on the sealing strip both sides of living and guide rail bottom are close to the gap between the sealing hook rail, reach the order ground of hydrodynamic reciprocating sealing.Otherwise when the packaged type ventilated port moves to left then.
The material and the shape of sealing strip of implementing key of the present utility model and be to live will be selected suitably, and material tensile deformation is little, and elasticity will be got well, and abrasion resistant fire blocking is good, and shape will be convenient to be pressed into the main pipe opening, can support sealing strip alive when interior hook is opened.
The utility model also can derive from into other need grow the movable seal arrangement of distance.
