Abstract
The utility model provides an explosion-proof device which comprises a burning furnace body. A hearth is arranged in the burning furnace body, an explosion-proof device body is further installed on the burning furnace body, and the number of the explosion-proof device body is at least one. The explosion-proof device comprises a flange cover, a spring, a pressure release plate, an end cover and a bolt. The pressure release plate is fixed on the flange cover, connected with the end cover through the bolt, the spring is arranged between the pressure release plate and the end cover, and two ends of the spring are respectively fixed in the pressure release plate and the end cover. The explosion-proof device is capable of preventing explosion due to the fact that air pressure in the burning furnace is too high.
Description
Technical field
The utility model relates to a kind of flameproof apparatus, refers to especially the flameproof apparatus of a kind of combustion gas or oil fired furnace.
Background technique
Existing oil fired furnace needs oil spout to light a fire when igniting, enters in stove as loss of ignition oil, needs oil spout again in igniting, if repeatedly have the phase to acquire a certain degree in not successful stove, easily produces blast during igniting; Furnace inner space is less, and is as excessive in the concentration of fuel oil or rock gas, and flue gas is too fast because of flue gas velocity, can't in time discharge, and produce blast, and the excessive oil circuit that easily makes of air pressure damages and easily injure operator.
The model utility content
The utility model proposes a kind of flameproof apparatus, solved in prior art too fastly because of flue gas velocity, can't in time discharge, and produce the problem of blast.
The technical solution of the utility model is achieved in that a kind of flameproof apparatus, comprise the burner body, be provided with burner hearth in described burner body, on described burner body, flameproof apparatus is installed also, the number of described flameproof apparatus is one at least, described flameproof apparatus comprises blind flange, spring, pressure relief plate, end cap, bolt, described being bolted on blind flange, described pressure relief plate and end cap all are connected on bolt, described spring is arranged between pressure relief plate and end cap, and the two ends of described spring are separately fixed in pressure relief plate and end cap.
Further comprise, also be provided with flange on described burner body, described flange and blind flange are equipped with.
Further comprise, the number of described flameproof apparatus is two.
Beneficial effect: the utility model has solved the defective that exists in the background technique, by an explosion-proof air releasing device is installed on burner, has solved because furnace inner space is little the excessive problem that easily sets off an explosion of air pressure during burning.By a spring mechanism is installed on flange, when making the stove internal air pressure acquire a certain degree, can back down the plate that loses heart and lose heart, reach the purpose of pressure release.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is an embodiment's of the utility model structural representation;
Fig. 2 is flameproof apparatus structure for amplifying schematic diagram in Fig. 1;
Wherein: 1, the burner body; 2, flameproof apparatus; 3, burner hearth; 21, blind flange; 22, spring; 23, pressure relief plate; 24, bolt; 25, end cap.
Embodiment
as Fig. 1, shown in Figure 2, a kind of flameproof apparatus, comprise burner body 1, be provided with burner hearth 3 in burner body 1, burner body 1 is provided with outlet pipe, flange is installed on outlet pipe, flange is provided with blind flange 21, these practical characteristics are to arrange flameproof apparatus 2 on blind flange, flameproof apparatus 2 is minimum on whole burner body 1 is provided with one, the utility model is selected 2 flameproof apparatuss 2, flameproof apparatus 2 comprises blind flange 21, spring 22, pressure relief plate 23, end cap 25, bolt 24, bolt 24 is fixedly welded on blind flange 21, described pressure relief plate 23 and end cap 25 are arranged on bolt 24, described spring 22 is arranged between pressure relief plate 23 and end cap 25, the two ends of spring 22 are separately fixed in pressure relief plate 23 and end cap 25.Pressure in furnace 3 surpasses specified value, gas is by the relief hole on blind flange 21, pressure relief plate 23 is pressed on the top, make Compress Spring 22, pressure relief plate 23 separates with blind flange 21, and gas is just discharged by space between pressure relief plate 23 and blind flange 21, carries out pressure release, protection burner hearth 3 is not excessive because of the concentration of fuel oil or natural gas, produces detonation; Flue gas is too fast because of flue gas velocity, can't in time discharge, and produce blast, and this device can solve.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
