Abstract
The utility model provides an industrial furnace with a safety explosion protection device, which mainly comprises a furnace chamber surrounded by furnace walls and a furnace roof, and a nozzle installed on the furnace wall. The utility model is characterized in that a glow heater is installed inside the furnace chamber, explosion protection holes are formed on the furnace walls and/or the furnace roof, a fiber module is arranged inside each explosion protection hole, a hydraulic automatic reset device is installed outside the furnace chamber, and the hydraulic automatic reset device is connected with one explosion protection hole through a crank connecting rod. When the concentration of combustible gases inside the furnace chamber reaches a certain level (nozzle flame is inactive), the glow heater can instantly kindle the combustible gases, thereby generating slight impact waves. The explosion protection holes automatically open to protect the safety of the entire furnace chamber. At the same time, the hydraulic device outside the furnace chamber resets the explosion protection holes in a short period of time, to minimize the heat losses of the furnace chamber and to ensure continuous, safe operation of the production line. The utility model has the advantages of simple structure, practicality, less investment, high efficiency, simple maintenance, high reliability and low failure rate, and can effectively guarantee the safety of both the furnace chamber and operators.
Description
Technical field
The utility model relates to a kind of industrial furnace, especially a kind of industrial furnace that has the safety anti-explosive device.
Background technology
In the past, some middle-size and small-size industrial furnaces of China owing to fail to install flame detection, warning and explosion-protection equipment, cause furnace explosion to collapse and jeopardize the serious consequence of personal safety.After this, people generally adopt lever gravity explosion-protection equipment, but its effect is unsatisfactory.Reason be cover plate behind blastic deformation, its displacement of center of gravity, therefore the lever balance counterweight can not effectively compress the sealing burner hearth, needs often to change holddown plate and lever.
Summary of the invention
The purpose of this utility model is to provide a kind of industrial furnace that has the safety anti-explosive device; by in burner hearth, increasing glow heater and cooperating hydraulic pressure automatic reset device outside the burner hearth; protect whole burner hearth safety, simultaneously the outer hydraulic means of burner hearth resets at chien shih explosionproof hole in short-term.
The purpose of this utility model is to realize like this, a kind of industrial furnace that has the safety anti-explosive device, mainly comprise the burner hearth that furnace wall, furnace roof surround, and be installed in burner on the furnace wall, it is characterized in that: glow heater is installed in the burner hearth, furnace wall and/or furnace roof are provided with explosionproof hole, are provided with fibre module in the explosionproof hole; Burner hearth is equipped with the hydraulic pressure automatic reset device outward, is connected by crank connecting link between hydraulic pressure automatic reset device and the explosionproof hole.
The utility model is by increasing glow heater and cooperating hydraulic pressure automatic reset device outside the burner hearth in burner hearth; when satisfying that flammable atmosphere reaches finite concentration in the burner hearth (burner fray-out of flame state); glow heater can in time be lighted it; the shock wave that it produced is less; explosionproof hole is opened automatically; protect whole burner hearth safety; simultaneously the outer hydraulic means of burner hearth resets at chien shih explosionproof hole in short-term; ensure that the burner hearth heat is the least possible lost; and production line safe operation continuously; it is simple to have device structure; practical; small investment; the efficient height; safeguard simple; the reliability height; advantages such as fault rate is extremely low can effectively ensure burner hearth and operative employee's safety.Solve the industrial furnace that in the past adopted lever gravity explosion-protection equipment, blast impulse power is big, and cover plate can not effectively compress problems such as sealing burner hearth through the displacement of blastic deformation tailheaviness.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, now comprise H with a kind of being applicable to
2The heat treatment furnace of protective atmosphere is an example.A kind of industrial furnace that has the safety anti-explosive device of the present utility model, mainly comprise the burner hearth 3 that furnace wall 1, furnace roof 2 surround, and be installed in burner 4 on the furnace wall, it is characterized in that: glow heater 5 is installed in the burner hearth, furnace wall and/or furnace roof are provided with explosionproof hole 6, are provided with fibre module 7 in the explosionproof hole; Burner hearth is equipped with hydraulic pressure automatic reset device 8 outward, is connected by crank connecting link 9 between hydraulic pressure automatic reset device 8 and the explosionproof hole 6.The hydraulic pressure automatic reset device is made up of cylinder and pressure switch, and is by remote PLC control, chain with switching cylinder.
H
2Explosive range from 0～75%, possess extremely strong lethality.Therefore be necessary the H of low concentration very
2After-flame adopts electric glow heater to cooperate burner can effectively ensure the burner hearth security fast.Its reason is: when the flame detector system UV of burner photoelectric tube breaks down, burner is after-flame H effectively
2During etc. flammable atmosphere, glow heater can play a role, can be with H
2In time light, the shock wave that it produced is less, and explosionproof hole is opened automatically, protects whole burner hearth safety, and simultaneously the outer hydraulic means of burner hearth resets at chien shih explosionproof hole in short-term, ensure that the burner hearth heat is the least possible to scatter and disappear, and production line safe operation continuously.
Capital equipment parameter of the present utility model is as follows:
(1), cylinder parameter: a) rod diameter
B) stroke 160～170mm; C) pressure 0.4MPa;
(2), electric glow heater parameter: peak power: 4Kw;
(3), explosionproof hole material: the full fiber of steel construction housing+liner.
When burner hearth is built by laying bricks or stones, at first fibre module is placed in the explosionproof hole, and requires explosionproof hole and furnace lining to closely cooperate.Next installs hydraulic means, and requires operation freely.By designing requirement, when shock wave in the burner hearth during greater than 0.4MPa, explosionproof hole needs to eject automatically rush down pressure.Glow heater is installed at last at the intensive place of protective gas, is convenient in time light.
