Abstract
The utility model discloses a coal dust collector anti-explosion device and belongs to coal dust collecting equipment. The coal dust collector anti-explosion device is characterized in that the device is formed by a rectangular door frame and an explosion door, the door frame is fixed around the outer side of an anti-explosion hole, and the explosion door is fixed in the door frame. The explosion door is composed of a rectangular frame, an anti-explosion film and a silicon rubber sealing strip, and the anti-explosion film is pressed and sealed through the silicon rubber sealing strip and fixedly laid on the rectangular frame through bolts. The coal dust collector anti-explosion device has the advantages that the door frame is arranged on the outer side of the anti-explosion hole, the anti-explosion film is laid on the angle steel explosion door, the periphery of the angle steel explosion door is pressed through the silicon rubber sealing strip, and the sealing effect is good; when the anti-explosion film bursts, only the angle steel explosion door is replaced with an angle steel explosion door made well in advance, the maintenance process is convenient and rapid, high-altitude overhaul operation time is shortened, and overhaul quality is guaranteed.
Description
Technical field
The utility model belongs to coal powder collection equipment, relates in particular to the explosion-protection equipment that coal dust is manufactured collecting device.
Background technology
The powder coal milling system of metallurgy, electric power, selects sack cleaner to carry out coal powder collection conventionally.In order to prevent that coal dust explosion occurs in collection process, a safety anti-explosive hole is installed in each chamber of sack cleaner, and rupture pressure disc is installed above explosionproof hole.Shortcoming is rupture pressure disc explosion often in manufacturing process, need to change in time, in order to guarantee the sealing of the installation of rupture pressure disc, whole explosionproof hole framework has more or less a hundred bolt, changing a rupture pressure disc need to be at hundred bolt of high empty position demolition, installation, repair time is long, and labour intensity is large, the normal operation that impact is produced.
Summary of the invention
The defect existing in order to overcome prior art, the purpose of this utility model is to provide a kind of coal collector explosion-protection equipment, realizes quick-replaceable rupture pressure disc, shortens the repair time.
Coal collector explosion-protection equipment, comprises sack cleaner casing, and sack cleaner casing is provided with explosionproof hole, is characterized in, this device consists of rectangle doorframe and explosion proof door, and doorframe is fixed on surrounding outside explosionproof hole, and explosion proof door is fixed in doorframe; Described explosion proof door is comprised of rectangular frame, rupture pressure disc and silastic sealing strip, and rupture pressure disc, by silastic sealing strip press seal, is bolted and is laid on rectangular frame.
The utility model further improves, and described rectangle doorframe is made by steel plate, establishes 4-6 explosion proof door installing hole on it, and door frame welding is in the outside of explosionproof hole surrounding.
The utility model further improves, described explosion proof door is made by angle steel, the rectangle matching with doorframe, it is corresponding that angle steel one side is established the explosion proof door installing hole that 4-6 installing hole and doorframe establish, by positioning bolt, fixed, angle steel opposite side is established silastic sealing strip fixing hole, and rupture pressure disc is placed on rectangular frame, by silastic sealing strip, along rectangular frame surrounding, sealed, be bolted and be laid on rectangular frame; Described rupture pressure disc physical dimension is greater than rectangular frame physical dimension, and redundance turnup is folding, fills in rectangular frame and doorframe gap, increases the tightness of explosion proof door.
Compared with prior art, advantage is: in explosionproof hole outside, increase doorframe, rupture pressure disc is laid on angle steel explosion proof door, and angle steel explosion proof door surrounding is compressed by silastic sealing strip, good sealing effect; When rupture pressure disc explosion, as long as the angle steel explosion proof door of a well in advance is changed, maintenance process is convenient and swift, shortens the high-altitude maintenance activity duration, guarantees repair quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of coal collector explosion-protection equipment;
Fig. 2 is the utility model rupture pressure disc scheme of installation.
In figure: 1-sack cleaner casing, 2-explosionproof hole, 3-rectangle doorframe, 4-explosion proof door, 5-rectangular frame, 6-rupture pressure disc, 7-silastic sealing strip, 8-bolt, 9-positioning bolt.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model will be further described.
Embodiment can find out that by Fig. 1,2 coal collector explosion-protection equipment comprises sack cleaner casing 1, sack cleaner casing is provided with explosionproof hole 2, this device consists of rectangle doorframe 3 and explosion proof door 4, and doorframe is fixed on surrounding outside explosionproof hole, and explosion proof door is fixed in doorframe; Explosion proof door is comprised of rectangular frame 5, rupture pressure disc 6 and silastic sealing strip 7, and rupture pressure disc, by silastic sealing strip press seal, is fixedly laid on rectangular frame by bolt 8.
As seen from Figure 1, rectangle doorframe 3 is made by steel plate, establishes 4-6 explosion proof door 4 installing holes on it, and door frame welding is in the outside of explosionproof hole 2 surrounding.
As seen from Figure 2, explosion proof door 4 is made by angle steel, the rectangle matching with doorframe 3, it is corresponding that angle steel one side is established the explosion proof door installing hole that 6 installing holes and doorframe establish, by positioning bolt 9, fixed, angle steel opposite side is established silastic sealing strip 7 fixing holes, rupture pressure disc 6 is placed on rectangular frame 5, by silastic sealing strip, along rectangular frame surrounding, sealed, by bolt 8, be fixedly laid on rectangular frame, rupture pressure disc physical dimension is greater than rectangular frame physical dimension, and redundance turnup is folding, fill in rectangular frame and doorframe gap, increase the tightness of explosion proof door.
