Abstract

The utility model relates to a mechanical fuel filled igniter, mainly comprising an adjusting hand wheel (1), an adjusting pressure pad (2), a barrel body (3), a fuel tank (4), a barrel body top cover (5), a connecting tube (9), a positioning pad (7), a connecting tube (10), a fan housing [11], an igniter [12], a burner tip [13] and one-way valves [4a], [14]. The utility model with the advantages of simple structure, reasonable structure, flexible switch when using, easy ignition and safe, clean and civilized operations is suitable for igniting various stoves in petrochemical industry.

Description

Igniter for gaseous fuel in stove

The utility model belongs to a kind of lighter that fuel is housed of machinery, is applicable to all kinds of stove igniting of petrochemical industry.

At present, each class A furnace A of petrochemical industry, pyrolysis furnace, SECTION TUBE FOR HYDROGEN MANNU-FACTURING FURNACE etc., when driving, great majority still adopt torch or Electric spark ignitor to ignite.

The igniting of torch formula generally is with ready-made torch, dips in fuel oil, and point catches fire, and sends into and goes in the stove to ignite.This mode was both dangerous, unclean again civilization.In addition, existing newly-designed all kinds of stoves according to requirement on environmental protection, have all increased muffler at the burner afterbody, thereby igniting brings bigger difficulty to torch.

Electric spark ignitor generally comprises increasing apparatus, electric firelock etc.Structure is complicated, and volume is big, needs power supply, lead during use, and program is various.More distinct issues are, general industry when driving, is negative pressure state with stove in the furnace chamber, and the spark of beating with Electric spark ignitor is little, is taken away easily, causes to be difficult for the disposable burner that ignites.

The purpose of this utility model is, in order to overcome the defective that above-mentioned igniter exists, designs a kind of simple in structurely, and safe and reliable during use, flexibly, health reaches the disposable burner that ignites, and is suitable for the novel igniter that all types of industries stove is used.

Formation of the present utility model comprises cylindrical shell (3), fuel tank (4), cylindrical shell top cover (5), tube connector (9), tracheae (10), fan housing (11), lighter (12), burner (13), its main points are in cylindrical shell (3) bottom an adjustment handwheel (1) to be housed, can promote to adjust pressure pad (2), fuel tank (4) is moved forward, and when the jet pipe on the fuel tank (4b) pushed up locating pad (7), the check valve (4a) on the fuel tank (4) was opened, the fuel gas ejection, by tracheae (10), back down the check valve (14) in the burner (13), through igniter (12), light the fuel gas of ejection from burner (13), just can light the stove burner.Move backward when adjusting handwheel (1), the check valve (4a) on the fuel tank (4) is closed immediately, and the check valve in the burner (14) is closed thereupon, and igniter just extinguishes immediately.

Now be described further in conjunction with the accompanying drawings:

Fig. 1 is the utility model assembling semi-section schematic diagram, also is case study on implementation of the present utility model.

Screw rod (1a) on the adjustment handwheel (1) among Fig. 1 passes cylindrical shell (3) bottom surface, withstands on to adjust on the pressure pad (2), adjusts pressure pad (2) another side and pastes mutually with fuel tank (4) bottom surface, and the adjustment along with adjusting handwheel (1) can move forward and backward.

Seal in the cylindrical shell (3) for fear of fuel gas, a boss is arranged, adorn a sealing software (6) between the jet pipe (4b) on it and the fuel tank (4) in cylindrical shell top cover (5) inboard.Near sealing software (6), a locating pad (7) is housed, it with tube connector (9) between put O ring (8), push down O by the pretightning force of tube connector and encircle, make that gas is unlikely to leak outside.The termination of the jet pipe (4b) that is connected with check valve (4a) withstands on the locating pad (7).Burner (13) is contained in tracheae (10) front end, in adorn a check valve (14), add a fan housing (11), on fan housing (11) breech face, have the air door hole.

In order to the lighter (12) of sparking, adopt piezoelectric ceramics, its end of a thread of igniting is assemblied in the exit of burner (13).

Fig. 2 is the structural representation of the check valve (4a) on the fuel tank (4).

Check valve (4a) is by valve body (4a ₁), valve seat (4a ₂), valve rod (4a ₃), spring (4a ₄) form.Valve body (4a ₁), valve rod (4a ₃) and the capping (4c) of fuel tank (4) between a rubber gasket (4a is arranged ₅).Valve body (4a ₁) bottom with sidewall on a through hole (4a is respectively arranged ₇).Valve rod (4a ₃) be hollow pipe, with sealing gasket (4a ₅) valve rod (4a that is complementary ₃) on the position, have 2 symmetries and with the mutually perpendicular through hole (4a of valve rod axis ₆).

Opening of check valve (4a) is to move forward in fuel tank (4), makes the jet pipe (4b) that withstands on the locating pad (7), promotes valve rod (4a with reaction force ₃) move 2 through hole (4a on the valve rod backward ₆) move in the body cavity, like this, by the through hole (4a on the valve body. thereupon ₇) go into the fuel gas in the valve pocket, just can pass through through hole (4a ₆) enter in the valve rod, and be discharged from through jet pipe (4b).On the contrary, be moved to the left when adjusting handwheel (1), because the spring (4a in the valve body ₄) elastic force, fuel tank is moved to the left, the through hole (4a on the valve rod ₆) move into sealing gasket (4a thereupon ₅) the position, through hole is shut, and reaches the purpose of closing valve.

The significant advantage of the utility model is, simple and reasonable for structure, cost is low, and use procedure does not need to connect power supply, lead, and open and close are flexible, and igniting easily, and is safe and reliable, the cleaning civilization. A diameter is 40 millimeters, and long 150 millimeters burn pot is filled butagas, and can reach about 30 minutes service time. Therefore, good economy performance is fit to all kinds of petrochemical industry stove igniting and uses.
