Abstract
The utility model provides an explosion-proof heater, which comprises an upper shell and a lower shell, wherein the upper shell and the lower shell are connected in a fastened and sealed manner, a heating body is arranged on the upper shell, the heating body is mainly composed of a heating sleeve and a heating rod sleeved in the heating sleeve, a material inlet and a material outlet are formed on the sidewall of the lower shell, and a flow shielding plate is arranged inside the lower shell. The explosion-proof heater provided by the utility model is simple in structure, easy and simple to manufacture, low in manufacturing cost, convenient for maintenance and high in safety factor.
Description
Technical field
The utility model relates to a kind of explosion-proof heater.
Background technology
In industries such as chemical industry, often need some hydrocarbons of heating, like petroleum crude oil, paraffin and water-gas etc. because these materials all belong to inflammable, explosive material, therefore, to the specification requirement of these materials heating than higher.At present, the main method that these materials are heated is that the heating rod threading is formed calandria, between heating rod and sleeve pipe, is full of heated oils.Use heated oils as heat medium, avoided heater element and the direct of gas to contact.But there is following defective in this method: owing to the gas of heating has corrosivity usually, heated oils is leaked easily (1), dusty gas, and heater element is overheated, and the serious heater that possibly make burns, and causes the generation of accident; (2) complex structure, because the loss of heated oils, thereby need a whole set of systems such as fuel tank and fuel-quantity transducer; (3) maintenance cost is high.
The utility model content
The utility model technical problem to be solved is, improves a kind of simple in structurely, and safety coefficient is high, the explosion-proof heater that maintenance cost is low.
The utility model solves the technical scheme that its technical problem adopted: a kind of explosion-proof heater; Comprise upper shell and lower house; Said upper shell and lower house are fastened and connected, and said upper shell is provided with calandria, said calandria mainly by heating muff with place the heating rod of heating muff to constitute; The sidewall of said lower house is provided with material inlet and material outlet, and the inside of said lower house is provided with aft cover plate.
Further, said aft cover plate is curved.
Further, said lower house is provided with heat-insulation layer.
Further, be equipped with heat medium between said heating muff and the heating rod.
Further, the preferred silica gel of said heat medium.
The utlity model has following advantage: (1) is simple in structure, and is easy and simple to handle, and low cost of manufacture is easy to maintenance; (2) adopt the arc aft cover plate, can reduce circulating resistance, accelerate velocity of liquid assets, improve convection transfer rate; (3) lower house is provided with heat-insulation layer, can reduce thermal losses, improves capacity usage ratio; (4) use silica gel to serve as heat transferring medium, can reduce the possibility that heat transferring medium leaks, security is higher; (5) omitted the parts such as fuel tank of general explosion-proof heater, improved sealing simultaneously, safety coefficient is high in inflammable and explosive environment.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
With reference to accompanying drawing; Present embodiment comprises upper shell 1 and lower house 6; Said upper shell 1 is fastened and connected with lower house 6, and said upper shell 1 is provided with calandria, and said calandria is by heating muff 5 and place the heating rod 3 of heating muff to constitute; The sidewall of said lower house 6 is provided with material inlet 7 and material outlet 2, and the inside of said lower house 1 is provided with aft cover plate 9.
Said aft cover plate 9 is curved.
Said lower house 6 is provided with heat-insulation layer 8.
Be equipped with heat medium 4 between said heating muff 5 and the heating rod 3.
Said heat medium 4 is a silica gel, certainly, also can adopt other similar heat mediums.
In the course of the work, because silica gel 4 is always solid state,,, also can guarantee safety even if sleeve pipe 5 is corroded so there is not the possibility of leakage; Since lower house 6 covering and heat insulating layers 8, thereby can reduce thermal losses, thus realize energy-conservation; Owing to be provided with arc aft cover plate 9, when gas enters into the process of discharging from material outlet 2 from following material inlet 7, the circulating resistance of gas is lower, and velocity of liquid assets is accelerated, and convection transfer rate is improved.
