Be provided with the straight carrying roller 7 in the end for fixing lower belt between the baffle plate 2 of the both sides of this lower house 3, guarantee that lower belt is not unsettled, also be provided with on the baffle plate 2 of its both sides and clear up slag door 4, be convenient to the dross coal that falls in this box Belt Conveying passage is cleared up, and needn't carry out whole dismounting to this device, improved efficiency.
Described movable flashboard 9 is rectangle, and bottom is the arc surface of evagination; Described upper sealing plate 5 is rectangle, and top is the concaved circular cambered surface that the outer convex arc surface with movable flashboard 9 bottoms adapts.
Described upper sealing plate 5 is rectangle, and the upper and lower of upper sealing plate 5 is equipped with rubber wear-resisting plate 8; Described lower shrouding 6 is rectangle, and the top of lower shrouding 6 is provided with rubber wear-resisting plate 8.
This distinguished and admirable spacer assembly in full-automatic belt lane, as belt lane counterflow-preventing air door casing for colliery, its structure is rectangle, and each specification manufactures and designs according to the dimensional requirement of standard belt, this casing is divided into upper shell 1 and lower house 3 two parts, and be formed by fixedly connecting with bolt, this upper shell 1 and lower house 3 form by whole sheet material compacting, and this body structure is simple, lightweight, compressive strength is high, and this casing is assembly, tears fortune open convenient.
The application state of this distinguished and admirable spacer assembly in full-automatic belt lane as shown in Figure 3, in order not to be subject to 15 distortion of air door stone walling, the distinguished and admirable spacer assembly 14 in full-automatic belt lane is damaged, this device adopts casing and the parallel connected mode of air door stone walling 15, when 15 construction of air door stone walling, pre-buried connection leading screw need to be placed in advance around air door stone walling 15 preformed holes, leading screw is inserted on the flange 12 of this device upper shell 1, this device level that guarantees two ends is consistent, then travelling belt 17 is passed to the corresponding passage of all casings, the straight carrying roller 7 in the end is installed, guarantee that belt is not unsettled, travelling belt 17 is connected with the large lane 16 of travelling belt.Connect cylinder 11 and movable flashboard 9, the debugging of ventilating.
The operating principle of this distinguished and admirable spacer assembly in full-automatic belt lane is: as shown in Figure 4, belt shipper is started to contact 18 extracting power supply cords, and receive on Pneumatic solenoid valves 23, opening, stopping forming of the open and close of cylinder 11 and belt conveyor is chain, when work plane produces coal, be arranged on the electromagnetic valve action in the conveyer switch, open air line, Pneumatic solenoid valves 23 control cylinders 11 shrink and pull open movable flashboard 9, and belt conveyer time delay 10-15 opens second; When work plane stops producing coal, when belt conveyor shuts down, electromagnetic valve action in the conveyer switch, Pneumatic solenoid valves 23 control cylinders 11 stretch out, close movable flashboard 9, simultaneously, tunnel blast source of the gas 19 is controlled airduct stop valve 20 and is opened, the gas of box house is discharged after air filter 21 filters, the whereabouts of assurance activity flashboard 9, control and leak out to greatest extent, reduces distinguished and admirable loss.When work, with the gas breaker device, support the use, when work plane generation coal and Gas Outburst, certainly will cause gas exceeding limit, make the gas electric shutting action by firedamp sensor, cut off all power in tunnel, thereby disconnect the gauge tap of belt conveyor, Pneumatic solenoid valves band dynamic air cylinder 11 falls rapidly movable flashboard 9, and movable flashboard 9 falls the space between rear enclosed casing and belt automatically, cut off the pernicious gas counter-flowing path, avoid the expansion of accident.
When the laggard wind that works of installation is debugged, adjust exhaust regulating valve 22, make the falling speed of movable flashboard 9 meet the belt inertia time, the phenomenon of card appears if descend, need control cylinder 11 that it is raised to the highest, then by the method for shimming, make movable flashboard 9 in suitable position.
This device is when belt is pneumatic, these activity flashboard 9 automatic liftings are to the casing top, do not affect the transportation of raw coal, once coal and Gas Outburst occur, gas outage locking makes tunnel power supply dead electricity, and Pneumatic solenoid valves 23 is opened cylinder 11 automatically, movable flashboard 9 falls, by channel enclosed, prevent that the coal of adverse current and gas from entering by the protrusion-dispelling air door fresh distinguished and admirable, the disaster that causes the accident enlarges.This device adapts to the zone of all mine belts transportations lane needs Ventilation Control, and this device has the outage closing function in addition, with the gas breaker device, supports the use, more outstanding at high gas, its safety effect of high projecting mine.
Add flame retardant rubber screen 13 at the middle part of this device box, play the reduction blast, prevent that air door from producing dust in running, minimizing is leaked out, can in casing, add a plurality of flame retardant rubber screens 13, the fresh wind in high blast district is carried out to the prevention of continuous interval, further enclosure space.
