Abstract
The utility model relates to a spring type explosion preventing door of a heating furnace, and relates to a spring type explosion preventing door of an oil convey pipeline heating furnace, aiming to solve the problems such as poor safety, possibility of hurting working personnel in case of explosion of the heating furnace, poor leak tightness, and overheat of the explosion preventing door and surface of surrounding furnace body, of the explosion preventing door of a known oil convey pipeline heating furnace, which adopts a negative pressure dead weight type explosion preventing door. The explosion preventing door provided by the utility model is mounted on the rear wall of a radiating chamber of the furnace body through flanges, an explosion door is arranged on the explosion preventing door and is movably connected to screw rods fixed on the flanges of the explosion preventing door, and the explosion door is fixed on the furnace body through springs and nuts on the screw rods. The explosion preventing door improves the leak tightness and safety of the heating furnace, combines the explosion preventing door and the personnel in/out hole into one, and reduces holes on the furnace body, so that air leakage and overheat caused by holes are avoided.
Description
Technical field
The utility model relates to a kind of heating furnace explosion proof door, relates to a kind of oil pipeline heating furnace spring explosion proof door that is used for specifically.
Background technology
Existing oil pipeline heating furnace, mostly be the direct-type tubular heater, be the negative pressure stove, exist fuel gas to surpass furnace pressure in the stove when heating furnace is worked and quick-fried spray takes place, and heating furnace body is damaged, need on heating furnace body, to install explosion proof door additional and carry out pressure release, known explosion proof door is on heating furnace radiation chamber Hou Qiang top explosion proof door to be set, explosion proof door is a negative pressure dead-weight explosion proof door, and extensively adopt as the most frequently used explosion proof door of oil pipeline heating furnace, its advantage is simple in structure, low price.Its shortcoming is to have poor stability, defective such as injure the staff easily during the quick-fried spray of heating furnace, sealing is poor, and explosion proof door and peripheral body of heater surface are overheated easily.In addition, the staff who also is provided with maintenance body of heater inside on body of heater goes out the entry and exit hole, owing to increased the perforate quantity of body of heater, therefore, because perforate causes hot-spot and defective such as leaks out.
Summary of the invention
The purpose of this utility model is at above-mentioned deficiency, and a kind of security, the good seal performance that propose, the heating furnace spring explosion proof door that explosion proof door and staff's access hole are united two into one.
Technical solution of the present utility model is: heating furnace spring explosion proof door is: be installed in that the explosion proof door on the wall is provided with the explosion door behind the body of heater radiation chamber, the explosion door is movably connected on the screw rod fixing on the explosion proof door flange, and the explosion door is fixed on the body of heater by spring on the screw rod and nut.
Explosion proof door described in the technical solution of the present utility model adopts bolt to be connected by the flange of the shell ring on flange and the body of heater, and the side of explosion proof door is connected with shell ring by rotating shaft.
Screw rod described in the technical solution of the present utility model evenly is fixed on its same radius circumference along the vertical of explosion proof door flange, and an end of spring withstands on the explosion door, and the other end is fixed with steel plate and nut.
Quick-fried end behind the door described in the technical solution of the present utility model is provided with peephole.
The operation principle of explosion proof door is when having fuel gas in the stove; may cause burner hearth or back-end ductwork generation detonation or second-time burning; cause furnace pressure to raise, when pressure is increased to certain value, can open pressure release voluntarily, with the safety device of protection heating furnace body.The utility model is owing to adopt the spring explosion proof door, having solved the oil transportation heating furnace adopts deadweight turnover plate type explosion proof door to have poor stability, the defective of sealing difference, explosion proof door of the present utility model adopts bolt to be connected with body of heater, also be connected with rotating shaft between explosion proof door and the body of heater, therefore, special staff's access hole must be set, avoided explosion proof door and staff's access hole place to leak out easily, thereby improved the security and the serviceability of oil transportation heating furnace with overheated.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
The specific embodiment
As Fig. 1, shown in 2, on wall behind the heating furnace radiation chamber, be provided with the hole of a 400mm, to be welded on this place, hole by the shell ring 9 that steel plate is made, the end that shell ring 9 stretches out body of heater is provided with adpting flange 6, be used for being connected with explosion proof door, the adpting flange of explosion proof door is connected with shell ring 9 adpting flanges 6, and be connected and fixed with bolt, adopt the sealing of asbestos seal band behind explosion proof door and the radiation chamber between wall, the screw rod 1 that to be vertically installed with four length on the explosion proof door flange be 370mm, four screw rods 1 are evenly distributed on the same radius circumference of explosion proof door flange, on explosion proof door, be provided with explosion door 5, the circumference of explosion door 5 is provided with and corresponding hole, four deep-rooted screw rod 1 positions, and explosion door 5 is contained on the screw rod 1 by this hole, and explosion door 5 can move horizontally on screw rod 1, on four screw rods 1, spring 4 is housed respectively, one end of spring 4 withstands on the explosion door 5, and the other end is by steel plate circle 8 and nut 2, the spring 4 that pad 3 will be inserted on the screw rod 1 carries out fastening compression, thereby explosion door 5 is fixed on the body of heater.When quick-fried spray took place heating furnace, quick-fried spray pressure promoted explosion door 5 and the spring 4 on the explosion proof door, discharged furnace pressure.Spring 4 rapid pressurizeds shorten; When venting of dust explosion pressure during less than certain value, spring 4 can recover automatically, closes the explosion door 5 on the explosion proof door.Because spring 4 design surplus capacities are bigger, problem can not deform.The side of explosion proof door also is connected with shell ring 9 on the body of heater by rotating shaft 10, when shutdown maintenance, unload the connecting bolt between shell ring flange 6 and the explosion proof door flange, can open explosion proof door easily, thereby play the effect that explosion proof door and staff's access hole unite two into one.Simultaneously be provided with one and see convex lens 11, can observe situation in the stove from the stove rear portion in the explosion proof door rear end.
