Abstract
The utility model relates to a long effect typed explosion-proof electric heater which belongs to the electric heating facility technological field. A chamber of the long effect typed explosion-proof electric heater is equipped with an inlet and an outlet, wherein heat insulation material is equipped on the outside portion, the upper portion fixes an explosion-proof chamber by a tube, the electric heating facility is connected with the inside of the chamber through the explosion-proof chamber by a tube, the upper cover of the flange mouth on the explosion-proof chamber is equipped with an explosion-proof chamber cover, a dent matched with the flange mouth on the explosion-proof chamber is made on the lower surface of the explosion-proof chamber cover, when deducting the cover, the flange mouth is equipped on the dent, a fastener goes through a flange hole from up to down and is fixed on a blind hole of the explosion-proof chamber cover. Although the explosion-proof electric heater is still vertically equipped outdoor, the possibility of a weeping doesn't exist, no matter for a seam crossing or for a gap between fasteners, thereby ensuring a faying face of the explosion-proof chamber over and the explosion-proof chamber flange, which can maintain a long time sealing and ensure the long-effect using life of the explosion-proof electric heater.
Description
Technical field
The utility model relates to a kind of anti-explosion electric heater, and especially a kind of improvement of anti-explosion electric heater hermetically-sealed construction belongs to electrical heating facility technology field.
Background technology
The function of existing anti-explosion electric heater is the fluid media (medium) heating with hydrogen, oil and so on, its basic structure is: the container system has import and outlet, the outside insulation material that coats, the upper end is fixed with explosion-proof chamber by one group of sleeve pipe, and electric heating device is penetrated in the container body by explosion-proof chamber by sleeve pipe.During work, the electric heating device energising is with the fluid heating that enters in the container body, again by outlet output.Because anti-explosion electric heater is the vertical open air that is installed in usually, bear the invasion and attack of natural climates such as wind, rain, snow all the year round, for fear of seepage, between explosion-proof chamber chamber cap and the explosion-proof chamber flange as shown in Figure 1, adopt flat seal (special provision is arranged, and surface smoothness need reach 6 grades).Yet, facts have proved, though above explosive-proof sealed face has O type rubber seal 3 sealing, aging with rubber ring As time goes on, rainwater will be easy to leak sealing surface from the hole of bolt 2.In addition, also having water between explosion-proof chamber chamber cap 1 and the explosion-proof chamber flange 4 immerses.Time one is long, the corrosion gradually of explosive-proof sealed face, and it is indoor that final infiltration just enters explosion-proof chamber, makes it can't reach requirement of explosion proof, also can produce electric spark when serious, destroys whole electric-control system, causes damage.
The utility model content
The purpose of this utility model is: the problem at above prior art exists by architecture advances, proposes a kind of long-acting type anti-explosion electric heater that can guarantee sealing effectiveness all the time.
In order to reach above purpose, the container system of long-acting type anti-explosion electric heater of the present utility model has import and outlet, the outside insulation material that coats, the upper end is by the fixing explosion-proof chamber of sleeve pipe, electric heating device is penetrated in the container body by explosion-proof chamber by sleeve pipe, buckle closure has the explosion-proof chamber chamber cap on the flange port of explosion-proof chamber, its improvement is: the lower surface of described explosion-proof chamber chamber cap is shaped on the groove that matches with the flange port of explosion-proof chamber, during buckle closure, described flange port is inlaid in the groove, securing member passes flange hole from the bottom to top, is fixed in the blind hole of explosion-proof chamber chamber cap.
Like this, though anti-explosion electric heater is still outdoor vertical installation, but owing to no matter be seam crossing or securing member gap, the possibility of all not having infiltration, therefore guaranteed that the faying face of explosion-proof chamber chamber cap and explosion-proof chamber flange can not get rusty, can keep sealing for a long time, guarantee anti-explosion electric heater long-acting service life.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the sealed structural representation of existing anti-explosion electric heater.
Fig. 2 is the structural representation of an embodiment of the utility model.
Fig. 3 is the partial enlarged drawing at A place among Fig. 1 embodiment.
The specific embodiment
Embodiment one
The long-acting type anti-explosion electric heater of present embodiment as shown in Figure 2, the corresponding relation of part and label is among the figure: explosion-proof chamber chamber cap 1, bolt 2, O shape rubber seal 3, explosion-proof chamber flange 4, explosion-proof chamber 5, sleeve pipe 6, electric heater 7, container body 8, heat-insulation layer 9, waterproof ring 10, blind hole 11, thermal insulation layer 12.
As seen from Figure 2, container body 8 is shaped on import and outlet, the outside heat-insulation layer 9 that coats the insulation material formation, and the upper end is by sleeve pipe 6 fixing explosion-proof chambers 5.Electric heater 7 is penetrated in the container body 8 by explosion-proof chamber 5 by sleeve pipe 6.Buckle closure explosion-proof chamber chamber cap 1 on the flange 4 of explosion-proof chamber 5.As seen from Figure 3, the lower surface of explosion-proof chamber chamber cap 1 is shaped on the groove that matches with explosion-proof chamber flange 4, forms the waterproof ring 10 of periphery.During buckle closure, be bumped into O shape rubber seal 3 on the flange after, be inlaid in the groove three applyings.Fastener bolt 2 passes flange hole from the bottom to top, screws in blind hole 11 internal threads that are fixed on the explosion-proof chamber chamber cap.
Theoretical and experiment all proves, even the long-acting type anti-explosion electric heater of present embodiment bears wind, rain, snow invasion and attack all the year round, because the explosion-proof chamber chamber cap is provided with waterproof ring structure (keeping) when machined into, can prevent that therefore sealing invades between explosion-proof chamber chamber cap and explosion-proof chamber flange.Bolt 2 is changed blind threaded (be commonly called as half hole thread, add the man-hour hole and do not get through) that upwards is screwed on the explosion-proof chamber chamber cap from following, can intercept water fully, make it can't enter explosive-proof sealed.In addition, fitting tightly (meeting explosive-proof sealed the special provision among GB3836.1～3-2000) of explosion-proof chamber chamber cap and explosion-proof chamber flange composition surface helps avoid the aging of O type rubber seal, thereby guarantees long-term anhydrous infiltration, can not get rusty, have long-acting service life.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
