Description
Technical field
The utility model is a kind of strong-ampere energy-saving explosion-proof electric heater, is used for flammable explosive gas environment (also can be used for non-flammable explosive gas environment), converts electrical energy into heat energy, and media such as various oil, gas, water are heated, and improves the temperature of medium.
Background technology
Original technical scheme mainly is made up of explosion-proof wiring cavity, tube sheet, electrothermal tube heat radiation sleeve pipe, temperature sensor heat radiation sleeve pipe, flanged plate, electrothermal tube, temperature sensor, thermometric pillar etc., has following defective:
1, undercapacity, poor safety performance.Anti-explosion electric heater heating cavity and external environment seal, in order to reach sealing effectiveness, earlier tube sheet, flanged plate are welded on electrothermal tube heat radiation sleeve pipe, temperature sensor heat radiation sleeve pipe two ends respectively, again with electrothermal tube and the welding of electrothermal tube heat radiation sleeve pipe, thermometric pillar and the welding of temperature sensor heat radiation sleeve pipe, the weld seam of solder side is many and disperse, crackle in use easily takes place in the bonding strength deficiency; The caliber of electrothermal tube heat radiation sleeve pipe, temperature sensor heat radiation sleeve pipe is less, and thickness of pipe wall has only 1-2mm, and intensity is limited, with tube sheet and flanged plate be to be welded to connect, be to guarantee radiating effect, long-term exposed outside, influenced by external force to cause the probability that damages bigger, very likely cause security incident.
2, thermometric is inaccurate, and temperature sensor is fragile.Temperature sensor is to be inserted in the thermometric pillar, with clamp thermometric pillar and electrothermal tube is fixed.During anti-explosion electric heater work, temperature is passed to the measurement pillar from the electrothermal tube surface, be passed to temperature sensor by the thermometric pillar again, the temperature of temperature sensor measurement and electrothermal tube surface actual temperature error are bigger, can not accurately measure real time temperature, can't accurately regulate and control power output, cause waste of electric energy; In electrothermal tube when heating,, along with the rising of temperature, electrothermal tube and thermometric pillar coefficient of thermal expansion are inconsistent, thereby thermometric pillar and electrothermal tube generation are misplaced, and the welding position of thermometric pillar is impacted; After stopping heating, the electrothermal tube temperature falls after rise, and length and thermometric pillar after electrothermal tube shortens are inconsistent, make the flexural deformation of thermometric pillar, causes temperature sensor to damage.
Summary of the invention
Technical problem to be solved in the utility model is: the anti-explosion electric heater that a kind of intensity height, safe and reliable and saves energy are provided.
For solving the technical scheme that above technical problem takes is such: remove electrothermal tube heat radiation sleeve pipe and temperature sensor heat radiation sleeve pipe, the mouth of pipe place of electrothermal tube and thermometric pillar is welded on the flanged plate respectively; The powder cylindrical shell is filled in welding on the flanged plate end face; Filling welding venting valve seat on the powder cylindrical shell circle; On filling powder body end surface, weld casting resin cylinder; On casting resin cylinder end face cylindrical, weld tube sheet; At tube sheet end surface circle welding explosion-proof wiring cavity.In filling the powder cylindrical shell, closely fill powder with insulation, heatproof, heat transfer; In casting resin cylinder, water and completely have insulation, heatproof, coagulate the firm resin in back.The fore-end of temperature sensor does not have the thermometric pillar; A Ω shape expansion joint is designed, is made in temperature sensor fore-end relevant position.
Because adopt above technical scheme, its effect is conspicuous:
1, strengthened security performance.Flanged plate is to be connected with filling powder cylindrical shell, casting resin cylinder, tube sheet with the explosion-proof wiring cavity, has only the solder side of four circumference between them altogether, and weld seam is few and concentrated, and the bonding strength height in use can not crack.The filling powder has the effect of insulation, heatproof, heat transfer, the electrothermal tube hot junction can be transmitted to the heat of the electrothermal tube terminals at cold junction place, and conduction is given and filled the powder barrel wall fast, be dispersed into the space, heat radiation is good, and the temperature of electrothermal tube terminals can be not higher, eliminates safe hidden trouble.Fill powder and can improve the insulation property of electrothermal tube wiring and temperature sensor wiring, improved security performance.Fill a venting valve seat on the powder cylindrical shell, be used to install automatic blow off valve valve air relief, in the anti-explosion electric heater course of work, fill in the powder cylindrical shell and can produce some gases gradually, cylinder internal pressure is strengthened gradually, and when pressure arrived certain numerical value greatly, automatic blow off valve valve air relief can be opened automatically, get rid of the gas of accumulation in the cylindrical shell, make cylindrical shell external and internal pressure unanimity.Casting resin has insulation, heatproof, coagulates the firm effect in back, further improves the insulation property of electrothermal tube wiring and temperature sensor wiring, fixes the position of each wiring, and with the powder sealing and fixing in filling the powder cylindrical shell.The temperature sensor front end is fixed with clamp and electrothermal tube, the design of temperature sensor fore-end relevant position, Ω shape expansion joint of making, Zhang Yuhe by this expansion joint, eliminate temperature sensor and electrothermal tube and produce the phenomenon of dislocation at work, can not influence the welding position, temperature sensor can not damage.
2, accurate thermometric, energy savings.The fore-end of temperature sensor does not have the thermometric pillar, and the electrothermal tube surface temperature is directly passed to temperature sensor, and thermometric is accurate.Temperature signal sends automatic control cabinet to accurately, and the output heating power what just can accurately be regulated, control, and avoids waste of electric energy.
