Description
Technical field
The utility model relates to a kind of sealing gasket device of Explosion-proof globe, relates in particular to the sealing device of the body implosion guard lampshade of feeder, belongs to Belt Conveying machinery technical field.
Background technology
Feeder is widely used in the coal-grinding pulverized coal preparation system of thermal power generation unit.The raw coal that feeder is carried be by run coal bin on the body conveying belt that upper coal spout and the coal gate of feeder enters feeder, then be transported to the coal pulverizer import by the conveying belt through dropping coal pipeline and coal gate, complete the course of conveying of whole raw coal.Required in order to guarantee the normal operation of unit and repair and maintenance, it must be withstand voltage closed requiring the feeder body, good seal.Sealing air pressure in casing must be greater than the blast of coal pulverizer inlet, thereby can prevent that so just the coal pulverizer hot blast is by channeling to the burning that the feeder body causes belt conveyor on the dropping coal pipeline.Consider illuminating lamp mounting seat on the feeder body; pressure ring and Explosion-proof globe are installed all are positioned at casing inside; the three connection place is because sealing is not in place; often can cause the leakage of sealing air; cause the interior blast of body too small; alter on hot blast, coal dust raises up, and whole internal body observation degree is smudgy.Can not in time observe in body ature of coal ruuning situation and take measures for corresponding situation by the observation window of end door and side door.Alter on hot blast simultaneously that the accumulation that raises up can cause the situations such as internal body spontaneous combustion with coal dust, body is in transportation, due to Explosion-proof globe and mounting seat, between the installation pressure ring, the corresponding sealing gasket of nothing cushions the extruding force in transportation, easily causes breaking of lampshade.
Summary of the invention
The purpose of this utility model is to solve on hot blast to alter, and coal dust produces the accumulation generation spontaneous combustion that raises up because pressure is too small, and the problem that in transportation, lampshade breaks provides a kind of sealing gasket device of simple in structure, sealing effectiveness is good, cost is low Explosion-proof globe.
In order to achieve the above object, the utility model provides a kind of sealing gasket device of Explosion-proof globe, it is characterized in that, comprise the lampshade mounting seat, the lampshade mounting seat is connected with the outer ring that lampshade is installed pressure ring, the inner ring that lampshade is installed pressure ring is connected with sealing gasket, and the top of sealing gasket is connected with the lampshade mounting seat, and the bottom of sealing gasket is connected with the glass lamp shade coupling.
Preferably, described sealing gasket is shaped as the annular that two ends communicate.
Preferably, described sealing gasket comprises reducing and lower enlarging, is lower lock seaming around upper reducing and lower enlarging.
Preferably, the lower end of described lower lock seaming is provided with the circular arc chamfering side.
Preferably, the openings of sizes of the openings of sizes of described upper reducing and glass lamp shade is complementary.
The utility model by will a kind of special heat-resisting rubber gasket between Explosion-proof globe with mounting seat, install between pressure ring, prevent the interior sealing air leakage of body, seal, and prevent from transporting the improper lampshade that causes and break.The utility model is simple in structure, simple installation, easy to operate, cost is low, sealing effectiveness is good, reduced the leakage point on the body, can be widely used on Explosion-proof globe.

Description of reference numerals
1 is that lampshade mounting seat, 2 is installed pressure ring, 3 for spring washer, 4 is that glass lamp shade, 5 is that sealing gasket, 6 is bolt for lampshade, and 7 is body, and 8 is upper reducing, and 9 is lower enlarging, and 10 is lower lock seaming, and 11 is the circular arc chamfering side.
The specific embodiment
For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
Embodiment
The utility model is a kind of sealing gasket device of Explosion-proof globe, as shown in Figure 1, is a kind of structure assembling schematic diagram of sealing gasket device of Explosion-proof globe.Mainly formed by lampshade mounting seat 1, lampshade installation pressure ring 2, glass lamp shade 4, sealing gasket 5.By the sealing device that is interconnected to constitute to each other.
Lampshade mounting seat 1 is welded on the body 7 of feeder, under sink to body 7 inside lampshade mounting seat 1 bottom the connecting thread hole is arranged.Sealing gasket 5 directly is sleeved on the boss limit of glass lamp shade 4, and coupling mutually.After sealing gasket 5 was completed assembling with glass lamp shade 4, lampshade was installed pressure ring 2 and is sleeved on from bottom to top on the glass lamp shade 4 boss limits that are separated with sealing gasket 5, and namely lampshade inner ring that pressure ring 2 is installed is connected with sealing gasket 5.Lampshade mounting seat 1 is connected with the outer ring that lampshade is installed pressure ring 2, when lampshade is installed pressure ring 2 upwards suit is touched lower lock seaming 10 around sealing gasket 5, by rotary lampshade, pressure ring 2 is installed and is made the construction bolt hole on lampshade installation pressure ring 2 corresponding with the screwed hole of lampshade mounting seat 1 bottom.Complete the mutual connection of lampshade mounting seat 1, lampshade installation pressure ring 2, glass lamp shade 4, sealing gasket 5 by spring washer 3 and bolt 6, make top and lampshade mounting seat 1 close contact of sealing gasket 5.Thereby complete the integral sealing assembling of Explosion-proof globe.
As shown in Figure 2, be the schematic diagram of sealing gasket 5.Sealing gasket 5 adopts the heat resistant rubber materials, sealing gasket 5 be shaped as the annular that two ends communicate, its opening is up-small and down-big.Sealing gasket 5 comprises reducing 8, lower enlarging 9 and lower lock seaming 10, is lower lock seaming 10 around upper reducing 8 and lower enlarging 9.The lower end of lower lock seaming 10 is circular arc chamfering side 11.Good sealing function is played in circular arc chamfering side 11 and the glass lamp shade 4 tangent parcels in boss limit, namely goes up the openings of sizes of reducing 8 and the openings of sizes of glass lamp shade 4 and is complementary.Sealing gasket 5 is wrapped on Explosion-proof globe (glass lamp shade 4), comes whole fixed lamp-socket that pressure ring 2, lamp socket mounting seat 1, the mutual connection of Explosion-proof globe, the circulation that has effectively completely cut off body 7 inner airs are installed by attachment bolt.Tangent being close to of illuminating lamp overhead guard in the sealing surface of upper reducing 8 and glass lamp shade 4, the circulation that has completely cut off glass lamp shade 4 inside and body 7 inner airs, lower being close to along tangent on the sealing surface of lower enlarging 9 and glass lamp shade 4 boss limits, the leakage that has effectively completely cut off sealing air in body.
The utility model is located in the middle of can being widely used in feeder body lampshade mounting seat and pressure ring, owing to having fixed the once sealing gasket 5 of thickness, lampshade is installed pressure ring 2 and is not contacted with glass lamp shade 4, has avoided because the transportation extruding causes the break generation of situation of glass lamp shade 4.
