Abstract
The utility model relates to an electric heater which is mainly composed of a main pipe 1, a connection box 2, a heat exchange tube 3, an electric heating wire 4 and a filler 5, wherein, the main pipe 1 is provided with a position vane 6; the heat exchange tube 3 is coiled on the main pipe 1 in the spire mode and is fixed by the vane 6; the electric heating wire 4 is arranged in the heat exchange tube 3; the filler 5 is arranged between the heat exchange tube 3 and the electric heating wire 4; the connection box 2 is arranged on the end part of the main pipe 1; both ends of the heat exchange tube 2 enter the connection box 2 from the inner hole of the main pipe 1. The utility model has the advantages of simple structure, convenient use, good effect of the heat and high anticorrosion performance.
Description
The utility model relates to a kind of immersion electric heater that is used for solution.
At present, the existing electric heater that is used for the immersion heating of solution generally is to make of materials such as iron, aluminium, copper, titanium, stainless steel and quartz glass, its structural shape is that the single tube with certain above-mentioned material curves V-type, W type or straight barrel type, required resistance wire of placement and heatproof insulating packing seal and form in pipe, the electric heater of being made by above-mentioned material and method only is adapted to some not strong solution of corrosivity, to heating of some deep-etching solution, as hydrofluoric acid, sulfuric acid etc., there is not the electric heater of good corrosion resistance that can be general so far.
The purpose of this utility model is to provide a kind of electric heater of spiral straight pipe type highly corrosion resistant.
The purpose of this utility model is achieved in that it is by being responsible for 1, terminal box 2, heat exchanger tube 3, resistance wire 4, filler 5 is formed, and is provided with locating blades 6 on the person in charge 1, heat exchanger tube 3 is spirally coiled in to be responsible on 1, and fixing by blade 6, heating wire 4 is housed in heat exchanger tube 3, establishing between heat exchanger tube 3 and heating wire 4 completely has filler 5,2 of terminal boxes are located at is responsible for 1 end, and the two ends of heat exchanger tube 2 enter terminal box 2 by being responsible for 1 endoporus.
The utility model is simple in structure, and is easy to use, heats effectively, and resistance to corrosion is strong.
Below in conjunction with accompanying drawing structure of the present utility model is done detailed explanation
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the utility model joint design schematic diagram
Fig. 3 is the utility model vertical view
The utility model is responsible for 1, terminal box 2, heat exchanger tube 3, resistance wire 4, filler 5 is formed, be provided with locating blades 6 on the person in charge 1, heat exchanger tube 3 is spirally coiled in to be responsible on 1, and fixing by blade 6, heating wire 4 is housed in heat exchanger tube 3, establishing between heat exchanger tube 3 and heating wire 4 completely has filler 5, and 2 of terminal boxes are located at is responsible for 1 end, and the two ends of heat exchanger tube 2 enter terminal box 2 by being responsible for 1 endoporus.
Heat exchanger tube 3 of the present utility model adopts the thin arm tubule of polytetrafluoroethylene (PTFE), and filler 5 is a silica, is responsible for 1 and adopts insulating materials to make.
Heat exchanger tube 3 of the present utility model adopts the thin arm pipe of polytetrafluoroethylene (PTFE) to be spirally coiled in to be responsible for and goes up shaping, prolonged the length of heat exchanger tube 3, increased heat transfer surface area, it is low to have remedied the thermal conductivity factor of material own, the low weakness of surface power, to satisfy the needs of power, be full of silica filler in the heat exchanger tube 3, the heat that resistance wire is sent can distribute as early as possible, heat exchanger tube adopts the mode of many parallel connections simultaneously, its power load is shared by many resistance wires, is difficult for blowing, even blow one, remaining endure, because terminal box adopts full-closed structure, prevent that solution drippage and etchant gas from infiltrating, and guarantees that wiring is good.
