Abstract
The utility model relates to a safe explosion-proof device of a pipe type sintering furnace, which comprises a furnace pipe. A furnace pipe cover is arranged at the front end of the furnace pipe, an air inlet is arranged on the lower portion of the furnace pipe, an air outlet is arranged on the upper portion of the furnace pipe, a support sleeve pipe is arranged on the furnace pipe, a lower press plate is arranged at the top end of the support sleeve pipe, an upper press plate is fixed on the lower press plate, and an explosion-proof film is arranged between the upper press plate and the lower press plate. A sealing ring is respectively arranged on the inner sides of the upper press plate and the lower press plate, and the explosion-proof film adopts an aluminum foil. The explosion-proof device can remind operators to timely cut off a power supply before explosion happens in the furnace pipe. The safe explosion-proof device is simple in structure, related materials are easy to manufacture, and the aluminum foil is adopted to be the explosion-proof film. The aluminum foil cannot be reacted with hydrogen due to good stability and can be reused if no abnormal operation is conducted. The aluminum foil can bear pressure of air in the furnace under normal condition, and cannot crack caused by the normal pressure in the furnace.
Description
Technical field
The utility model relates to a kind of structure of tubular type sintering furnace, especially relates to a kind of safety anti-explosive device of tubular type sintering furnace.
Background technology
The tubular type sintering furnace is mainly used in the sintering of powder metallurgy contact, and tube furnace is made up of two parts: sintering furnace body, sintering furnace boiler tube.Sintering furnace body is made up of heating element heater and heat-insulation layer; Sintering furnace boiler tube as shown in Figure 1 is made up of boiler tube body, boiler tube lid, air inlet pipe, escape pipe, and sintered products holds in the boiler tube, and logical hydrogen is as the protection gas of sintered products, to avoid the oxidation of product in sintering process effectively in the boiler tube.Hydrogen is inflammable and explosive gas; When the aerial volumetric concentration of hydrogen is between 4.0%～75.6%; Meeting burning things which may cause a fire disaster will explode, and the sintering furnace boiler tube is a closed container, removes after the hydrogen that gives off must burn; Otherwise the hydrogen that gives off can cause potential safety hazards such as fire easily in indoor enrichment.In boiler tube, charge into hydrogen, at this moment igniting afterwards is difficult to measure the hydrogen content in the boiler tube; When hydrogen content in explosive range, hydrogen and oxygen reaction discharge huge energy; Cause the rapid expansion of gas in the boiler tube, can cause the boiler tube blast, cause security incident.
Summary of the invention
The utility model technical problem to be solved provides a kind of safety anti-explosive device of tubular type sintering furnace, and it can the preceding operator of prompting that blasts in boiler tube in time be cut off the electricity supply, and prevents the generation of security incident.
The technical scheme that its technical problem of the utility model solution is taked is: a kind of safety anti-explosive device of tubular type sintering furnace, comprise boiler tube, and the front end of boiler tube is provided with the boiler tube lid; The bottom of boiler tube is provided with air inlet; Top is provided with the gas outlet, and described boiler tube is provided with supporting sleeve, and the supporting sleeve top is provided with lower platen; Be fixed with top board on the lower platen, between top board and lower platen, be provided with rupture pressure disc.
For being can keep the safety in production in the boiler tube, gas leak phenomenon can not take place, the inboard of described top board and lower platen is provided with sealing ring.
Further, what described rupture pressure disc adopted is aluminium foil, and it can use for a long time, can not cause breakage because of weather, environmental factor.
The beneficial effect of the utility model is: after having increased explosion-protection equipment, the preceding operator of prompting that blasts in boiler tube in time cuts off the electricity supply; This apparatus structure is simple, and related material is easy to make; Adopt aluminium foil as rupture pressure disc because aluminium foil is stable very good, it not can with hydrogen reaction; If no abnormal operation, aluminium foil can use repeatedly; Under the normal condition, aluminium foil is enough to bear the gas pressure in the stove, can not break because of normal furnace pressure.
Description of drawings
Fig. 1 is the existing structure sketch map;
Fig. 2 is the utility model structural representation;
Fig. 3 is the utility model explosion-protection equipment sectional structure sketch map.
Among the figure: 1, boiler tube; 2, gas outlet; 3, boiler tube lid; 4, air inlet; 5, explosion-protection equipment; 5-1, locking nut; 5-2, rupture pressure disc; 5-3, top board; 5-4, sealing ring; 5-5, lower platen; 5-6, supporting sleeve.
The specific embodiment
A kind of as shown in Figures 2 and 3 safety anti-explosive device of tubular type sintering furnace comprises boiler tube 1, and the front end of boiler tube 1 is provided with boiler tube lid 3; The bottom of boiler tube 1 is provided with air inlet 4; Top is provided with gas outlet 2, and described boiler tube 1 is provided with supporting sleeve 5-6, and supporting sleeve 5-6 top is provided with and presses down the 5-5 plate; Be fixed with top board 5-3 on the lower platen 5-5, between top board 5-3 and lower platen 5-5, be provided with rupture pressure disc 5-2; The inboard of described top board 5-3 and lower platen 5-5 is provided with sealing ring 5-4; What described rupture pressure disc 5-2 adopted is aluminium foil.
When manipulating, when the pressure in the boiler tube 1 reached certain value, the aluminium foil in the explosion-protection equipment 5 can be broken through.Have explosion during the breaking of aluminium foil, operating personnel cut off source of the gas after hearing explosion, will effectively avoid the generation of accident.The general used thickness of aluminium foil is 0.2mm, and under normal circumstances, aluminium foil can use for a long time, can not cause breakage because of weather, environmental factor.After aluminium foil breaks, only need unclamp locking nut 5-1, take out the aluminium foil that breaks, change new aluminium foil, cover top board 5-3, locking locking nut 5-1, whole apparatus function has just recovered; This device is simple to operate, easy to maintenance, greatly reduces the generation of security incident.
