Abstract
The utility model discloses an electric heater for liquid, and belongs to an electric heater for heating liquid. A protective cylinder of the heater is welded on the sealed end face of a flange; a plurality of U-shaped electric heating pipes are uniformly distributed and fixed on a supporting flange, and extend into the protective cylinder from the rear part of the flange; the supporting flange is fixed on the non-sealed end face of the flange through screws; a heat conducting material layer is filled in the protective cylinder; a heat insulation material layer is filled between an inner hole of the flange and the U-shaped electric heating pipes; a waterproof cylinder is screwed on the front part of the flange, and a waterproof joint is fixed on the front end face of the waterproof cylinder and covered on a wire outlet in the front end face of the waterproof cylinder; and a grounding screw and a plurality of binding posts are fixed on the supporting flange, and each binding post is electrically connected with one end of each U-shaped electric heating pipe. Through the electric heater, the electric connecting part is separately isolated, and the liquid is indirectly heated, so that the operation safety is improved and the replacement operation is facilitated.
Description
Technical field
The utility model relates to electric heater, and particularly heat medium is the electric heater of liquid.
Background technology
Existing electric heating tube when particularly flammable oil product heats, is that heating tube directly is positioned over directly heating in the heat medium to liquid.Like this, on the one hand, because the electric connecting member of existing electric heating tube is exposed outside; Cause short trouble easily, the electric heater inside stuffing can pollute heat medium, on the other hand; Electric heater directly contacts with heat medium, in a single day electric heater itself the booster fault occurs, and inside stuffing can pollute heat medium; If heat medium is flammable oil, also have bigger potential safety hazard.The mounting means of general this type of electric heater is laterally inserted container bottom; In case break down; Need to stop production vessel empty could be changed, i.e. labor human and material resources, financial resources influence produced, and because flammable often oil of heat medium or corrosive liquids; Therefore also can bring other potential safety hazards, this product then can be changed by single light completion under the situation of the normal operation of equipment.
The utility model content
The purpose of the utility model provide a kind of electrical wiring part isolate separately, indirectly to heat medium liquid heated electric heater.
This novel purpose is achieved in that a kind of liquid electric heater, comprises electric heating tube, and protection cylinder is welded on the seal face of flange, and said electric heating tube is made up of several U font electric heating tubes; Several U font electric heating tubes are uniformly distributed with and are fixed on the pivot flange; The electric heating tube that is fixed on the pivot flange inserts protection cylinder from the non-tight end face of flange; And pivot flange is fixed on the flange non-tight end face through screw; Be filled with thermal conductive material layer in the protection cylinder, be provided with insulation material layer between flange endoporus and the several U font electric heating tube; Flange non-tight end face is connected with screw thread rotary joint style waterproof drum, and water joint is fixed on the waterproof drum front end face, and cover cap is on the wire hole on the waterproof drum front end face; The middle part of pivot flange is fixed with earthing screw, is fixed with a plurality of binding posts on the pivot flange, and each binding post is electrically connected with an end of a U font electric heating tube.
Above-mentioned thermal conductive material layer is made up of magnesia powder or heat-conducting daub.
Above-mentioned insulation material layer is made up of asbestos fibre or alumina silicate fibre.
Compare with existing electric heating tube, the utlity model has following characteristics:
1, the protection electric connecting member is avoided failed because.
2, when the electrothermal tube pipe explosion accident took place, the electrothermal tube content can not pollute heat medium, and heat medium can be not charged simultaneously.
3, be easy to after electrothermal tube breaks down change, can not influence user's manufacturing schedule.
The utility model all designs all electric connecting members in the protection terminal box; Degree of protection reaches IP56; Prevent that effectively short circuit accident from taking place, outside electrothermal tube, increase protecting sheathing simultaneously, fill Heat Conduction Material in the shell; When guaranteeing pyroconductivity, prevent electrothermal tube generation pipe explosion accident the adverse consequences that possibly bring.Changing more conveniently simultaneously, is replaceable electric heating tube under the situation that does not influence production, and need not be with the liquid emptying in the container.
Description of drawings
Fig. 1 is the structure chart of the utility model.
Fig. 2 is the profile of Fig. 1 along the A-A line.
The specific embodiment
Fig. 1, Fig. 2 illustrate; Protection cylinder 2 is welded on the seal face of flange 3 (being ring flange), and electric heating tube 1 is made up of several U font electric heating tubes, and several U font electric heating tubes are uniformly distributed with and are fixed on the pivot flange 11; The U-shaped electric heating tube is from ring flange non-tight end face backward (Fig. 1; Zuo Weiqian, right is the back) stretch in the protection cylinder, pivot flange is fixed on the flange 3 non-tight end faces through screw again; Be filled with thermal conductive material layer 8 in the protection cylinder, be filled with insulation material layer 7 between flange endoporus and the U-shaped electric heating tube; The anterior spiral of flange is connected with screw thread rotary joint style waterproof drum 4 (being lined with sealing ring 6 between waterproof drum 4 and the flange 3), and water joint 5 is fixed on the waterproof drum front end face, and cover cap is on the wire hole on the waterproof drum front end face; Above-mentioned pivot flange 11 (front end face) middle part is fixed with earthing screw 9, is fixed with a plurality of binding posts 10 (among Fig. 2 being 6) on the pivot flange (front end face), and each binding post is electrically connected with an end of a U-shaped electric heating tube.Power cable penetrates from water joint (the pg joint of standard), gets in the waterproof drum through the waterproof drum Top Leading-out Hole, is connected with binding post on the pivot flange.The U-shaped electric heating tube can be made the serial or parallel connection power supply mode as required.U-shaped electric heating tube place planar central is intersected between any two each other, and the intersection on two planes is crossed the axial line of protection cylinder.
Thermal conductive material layer 8 is formed (technology that heat-conducting daub can adopt ZL200610022543.9 the applicant development) by magnesia powder or heat-conducting daub.Insulation material layer 7 is made up of asbestos fibre or alumina silicate fibre.
