Description

A kind of heat treatment carburizing continuous oven igniter

Technical field

The utility model is related to a kind of heat treatment carburizing continuous oven manual ignition devices.

Background technology

In heat treatment procedure, part need to be inserted in the carburizing medium with protective atmosphere, be heated to 890~910 DEG C of list Phase austenitic area after keeping the temperature enough time, makes the active atoms of carbon decomposited in carburizing medium penetrate into steel part surface layer.Wherein n-formyl sarcolysine Alcohol atmosphere is protection gas, and acetone gas is carburizing medium.At present, the process is all complete on heat treatment carburizing continuous oven transfer matic Into.Carburizing continuous oven transfer matic is divided into preceding cleaning, pre-oxidation furnace, carburizer（By heating zone, Qiang Shen areas, diffusion region and heat preservation zone Composition）, quenching area, rear cleaning, tempering furnace, air-cooled.Carburizer is n-formyl sarcolysine alcohol protective atmosphere, and methanol and nitrogen are according to 1:1.1 Ratio enter in stove, nitrogen methanol atmospheres and acetone gas react the flammable gas such as CH4, CO and H2 of generation under the high temperature conditions Body, this flammable mixed gas is toxic and harmful gas, to reach《Discharge standard of air pollutants》, this combustibility mixing Gas part need to be discharged as exhaust gas after floss hole fully burns, therefore generally can set igniting in carburizer Waste gas outlet Device for lighting exhaust gas, makes flammable mixed gas fully burn.Its another effect is to generate to bear in carburizer stove When overwhelming suck, the air of suck-back can fully be burnt, to ensure that fuel gas does not contact generation with air in carburizer stove The danger of explosion.The discharge of existing carburizing furnace exhaust is using normally opened igniter, at the same time, there exists a further problem in that, if Standby power failure liquefied gas interruption or exhaust gas ignitor failure, line clogging etc., ignition tip extinguishes, and discharge is useless in carburizer stove Environment is polluted in the not ignited direct discharge workshop of gas, while exhaust gas is toxic to human body, assembles in smoke discharging pipe and also easily causes Fire and risk of explosion.There is the fuel gas of high concentration in the furnace lifting of carburizer, gas making and production process in stove, in order to ensure The leakproofness of carburizer need to hold torch and each maintenance door of carburizer, fire door, furnace roof etc. are detected, in case gas leakage is made The security risks such as forming apparatus and product quality.Industry universal way is to make the instruments such as torch with cloth wrapping viscous oil on iron staff To carry out combustible gas leakage detection to heat treatment carburizing continuous oven.There are the problem of be that can instill ground and to set after cloth viscous oil It is standby upper, there is the security risk for slipping, catching fire.

The content of the invention

The purpose of this utility model is to provide a kind of heat treatment carburizing continuous oven igniters, overcome former normally opened igniting dress The shortcomings that putting easily extinguishing and poor former leak detection torch security.

A kind of heat treatment carburizing continuous oven igniter, it is characterised in that：Including holding rod, outer tube, inner tube, fiery core, lock Tight screw, upper shield, holding rod connection outer tube, holding rod have Telescopic, inner tube insertion outer tube, and outer tube opens inverted f slot, and fiery core is inserted Entering inner tube, inner tube outer circle drilling and tapping, lock screw is mounted on fixing pipe endogenous fire core on inner tube screw hole, prevents fiery core from falling, Inner tube bottom seal prevents fuel from instilling ground, and after ignition operation, upper shield is sleeved on outer tube knock down the flame, and flame need not Extinguished with the methods of air blowing.

The utility model has the advantages that：The utility model holding rod has Telescopic, easy to operation, flexibly uses；Lock Tight screw can be by outer tube card slot fixed inner tube, fiery core, upper shield simultaneously, by lock screw, and when use pulls out inner tube and solid It is scheduled on outer tube card slot, exposes fiery core, the size of flame can be adjusted, and the longer flame of fiery core exposing is bigger, conversely, flame is more Small, when placement, pulls down, and fiery core is hidden in outer tube.Fiery core replacement is convenient and efficient, unclamps lock screw, removes fiery core, insert again Enter；After ignition operation, upper shield can need not be extinguished with knock down the flame with the methods of air blowing.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawings and detailed description：

A kind of heat treatment carburizing continuous oven igniter, it is characterised in that：Including holding rod 1, outer tube 2, inner tube 3, fiery core 4th, lock screw 5, upper shield 6, holding rod 1 connect outer tube 2, and holding rod 1 has Telescopic, can be extended when lighting exhaust gas, right Carburizer can shorten when being hunted leak, convenient for being operated in real work.Inner tube 3 is inserted into outer tube 2, and fiery core 4 is inserted into inner tube 3, 3 outer circle drilling and tapping of inner tube, 5 fixing pipe endogenous fire core 4 of installation locking screw, prevents fiery core 4 from falling, and 3 bottom seal of inner tube prevents Fuel instills ground.Fiery core 4 replace it is convenient and efficient, unclamp lock screw 5 remove fiery core 4, again insertable into.Outer tube 2 opens inverted f Slot, inner tube 3 are inserted into, and use or while placing can fix inner tube 3 position by lock screw 5, and when use, which pulls out, exposes fiery core 4, It is pulled down during placement, fiery core 4 is hidden in outer tube 2.Fiery core 4 is replaced with high-temperature fibre ceramics packing, is injected fuel, is made fiery core 4 Fuel is permeated, lights that rear flame combustion is lasting, the size of flame can be adjusted, and it is bigger that fiery core 4 exposes longer flame, conversely, fiery Flame smaller.Upper shield 6 is sleeved on outer tube 2, and after ignition operation, upper shield 6 puts on flame hole, while knock down the flame, and flame need not Extinguished with the methods of air blowing.

The above content is combine specific preferred embodiment further detailed description of the utility model, it is impossible to Assert that the specific implementation of the utility model is confined to these explanations.For the ordinary skill of the utility model technical field For personnel, make several equivalent substitute or obvious modifications without departing from the concept of the premise utility, and performance or Purposes is identical, then should be considered as belonging to the protection domain that claims that the utility model is submitted determine.
