Description
Technical field
This utility model is related to a kind of scrapper conveyor and in particular to a kind of scrapper conveyor explosion relief door, belongs to the technology of grain conveying
Field.
Background technology
The scrapper conveyor middle node deck portion of many domestic producers using explosion relief door in the form of be between two flanges
Press against one piece of stainless venting of dust explosion piece, can be by venting of dust explosion piece crimp until inciting somebody to action when the instantaneous pressure in scrapper conveyor housing is excessive
Whole venting of dust explosion piece is blown, thus reaching the effect of release pressure, but this design three weak point of presence:
(1) after venting of dust explosion piece pops, chip can splash everywhere, is likely to result in personnel's injury；
(2) venting of dust explosion piece price is higher, and the whole venting of dust explosion piece of each venting of dust explosion is required for changing completely；
(3) pressure in different operating mode housings is different, like this just may require that venting of dust explosion piece has a variety of types
Number could meet specific use requirement, for equipment general maintenance cause larger constant.
Utility model content
The purpose of this utility model is, provides scrapper conveyor explosion relief door, to overcome the disadvantages mentioned above existing for prior art
And deficiency.
First, it is to avoid personnel can be damaged during venting of dust explosion；
Secondly, reduce manufacturing cost, improve maintainability and the operability of equipment.
The drip irrigation device of solve problem, the form improved at present is the venting of dust explosion door using venting of dust explosion bolt, such as Fig. 1
With shown in Fig. 2:
The technical problem solving required for this utility model, can be achieved through the following technical solutions:
Scrapper conveyor explosion relief door is it is characterised in that include: scrapper conveyor body, cover plate, explosion relief door, venting of dust explosion bolt, flange, hinge
Chain etc..
Described scrapper conveyor body is provided with cover plate, and described cover plate is provided with explosion relief door, and described explosion relief door arranges venting of dust explosion bolt,
Described venting of dust explosion bolt is connected using flange with explosion relief door.
Wherein, venting of dust explosion pad is set between described venting of dust explosion bolt and flange.
Wherein, described cover plate makes rectangle or square structure using metal, and described cover plate arranges a plurality of letting out
Explosion bolt.
Wherein, hinge be by the clamping screw on explosion relief door together with being bolted on cover plate.
Wherein, described cover plate and flange arrange a plurality of hinges, and described hinge is 4 length is 25cm metal bracelet.
In normal use, explosion relief door can be fitted with flange under the pressuring action of venting of dust explosion bolt, excessive in instantaneous pressure
When, can by one of four venting of dust explosion bolts or all quick-fried fall, simply destroy venting of dust explosion pad, splashing will not be produced, in addition cover
Plate and flange be by 4 be up to 25cm about chain connection together with, even if cover plate pops to lift and also can in venting of dust explosion
Held by hinge, prevent cover plate from splashing and cause personnel to injure, after only needing to after the completion of venting of dust explosion change several venting of dust explosion bolts
Normal use, changes very convenient, will meet different pressure demand it is only necessary to incite somebody to action under different working conditions simultaneously
The size of explosion relief door suitably adjusts, and using the venting of dust explosion bolt of same model, versatility is extremely strong.
The beneficial effects of the utility model:
1st, this utility model adopts venting of dust explosion bolt, it is to avoid the possibility that can be caused casualties due to splashing during venting of dust explosion.
2nd, this utility model can be reconstructed on the basis of existing equipment, greatly reduces design and use maintenance cost.
3rd, this utility model only needs to improve the size of explosion relief door in the case of needing to meet different pressure requirements, increases
The design versatility of equipment, advantageously reduces unit type and promotes standardization.
Brief description
Fig. 1 is structural representation of the present utility model.
Fig. 2 is structural representation of the present utility model.
Reference:
Scrapper conveyor body 1, cover plate 2, explosion relief door 3, venting of dust explosion bolt 4, venting of dust explosion pad 5, flange 6.
Specific embodiment
Below in conjunction with specific embodiment, this utility model is made with progressive explanation.It should be understood that following examples are merely to illustrate
This utility model is not for restriction scope of the present utility model.
Embodiment 1
Fig. 1 is structural representation of the present utility model.Fig. 2 is structural representation of the present utility model.As shown in Figure 1-2,
Scrapper conveyor explosion relief door, comprising: scrapper conveyor body 1, cover plate 2, explosion relief door 3, venting of dust explosion bolt 4, venting of dust explosion pad 5, flange 6 and hinge 8.
Scrapper conveyor body 1 is provided with cover plate 2, and described cover plate 2 is provided with explosion relief door 3.Venting of dust explosion bolt 4 is arranged on explosion relief door 3.Let out
Explosion bolt 4 is connected using flange 6 with explosion relief door 3.
Venting of dust explosion pad 5 is set between venting of dust explosion bolt 4 and flange 6.
Cover plate 2 makes rectangle or square structure using metal, and described cover plate 2 arranges 4 venting of dust explosion bolts 4.
Cover plate 2 and flange 6 arrange a plurality of hinges.Hinge is 4 length is 25cm metal bracelet, and hinge 8 passes through locking
Bolt 7 is fixed together with the clamping screw 7 on cover plate flange.
As shown in Figure 1-2, venting of dust explosion bolt 4, in normal use explosion relief door 3 can under the pressuring action of venting of dust explosion bolt with method
Blue 6 laminatings.
When instantaneous pressure is excessive, can by one of four venting of dust explosion bolts 4 or all quick-fried fall, simply destroy venting of dust explosion pad
Piece 5, will not produce splashing, in addition cover plate 2 and flange 5 be by 4 be up to 25cm about the non-accompanying drawing of hinge illustrate to be connected to
Together, even if cover plate pops to lift and also can be held by hinge in venting of dust explosion, prevent cover plate from splashing, only need to more after the completion of venting of dust explosion
Can normally use after changing several venting of dust explosion bolts 4, change very convenient, will meet under different working conditions simultaneously
Different pressure demand is it is only necessary to suitably adjust the size of explosion relief door 3, using the venting of dust explosion bolt of same model, general
Property is extremely strong.
Above specific embodiment of the present utility model is illustrated, but this utility model is not limited thereto, only
Will be without departing from objective of the present utility model, this utility model can also have various change.
