Abstract
The utility model relates to a quartz glass liquid electric heating tube. The inner cavity of a quartz glass tube is divided into an upper part and a lower part which are a non heating zone and a heating zone by a heat insulating plate. A supporting tube on which a heating resistance wire is wound is positioned in the quartz tube and the heating zone which is positioned on the lower section of the quartz glass tube are supported by buffering fillings on the bottom of the quartz tube. An asbestos lining pad is arranged between the heating resistance wire and a supporting tube. The utility model can ensure the reliability, the durability, and the safety of an electric heating system. The service life is improved.
Description
The utility model relates to the electric-heating technology field, is a kind of solar water heater electrical auxiliary heater tool.
Present metal electric heating tube adopts metal tube to do oversheath, as copper pipe, stainless steel tube etc., puts in metal tube behind the heating resistance wire with magnesia filling insulation, seals port with silica gel then.In normal use, because its long period of soaking is in water or other liquid, insulating properties can progressively go down, and acid and alkali-resistance not, if lack liquid in the heating container, and electrical heating is when in running order, electric heating tube splits cruelly because of the sky burning can produce or is out of shape, once above-mentioned situation takes place, there is not the possibility of repairing, have only replacing.So not only service life short, and whole electric heating system reliability and security are difficult to ensure.
Existing conventional quartz electric heating pipe, its power outlet is drawn by two ends, because the restriction of structure, can only adopt horizontal mounting means, be about to the middle and lower part that the electric heating tube level is loaded on heating container, could operate after fluid discharge in the container must being gone out when maintenance and replacing, not only cause certain loss, also increase the maintenance of electric heating system and changed difficulty to the family.
At the problem that above-mentioned prior art exists, the utility model provides a kind of improved quartz glass liquid electric heating tube, and reliability, durability and security that it can guarantee electric heating system have improved service life.
The purpose of this utility model reaches by the following technical programs: electric heating tube is made of a quartz glass tube, there is a coiling on it to send out the pipe that drives away of thermal resistance wire in the pipe, its quartz glass tube cavity is divided into non-hot zone and hot zone up and down two partly by a thermal insulation board, and the stay pipe that thermal resistance wire is sent out in coiling is positioned at the hot zone of hypomere and is supported by the buffering filler of bottom.Between described thermal resistance wire and stay pipe, asbestos lining is arranged.
The heating tube resistivity height that the utility model provides, the dielectric strength height can not produce the insulating properties phenomenon that goes down in the liquid such as long period of soaking Yu Shui; Has preventing dry combustion design: under the empty situation of burning high temperature of no heating liquid,, can not produce and split cruelly and be out of shape, can not pollute and be heated liquid owing to the quartz glass coefficient of expansion is lower; Can be used for the heating of corrosive liquids; Be convenient to regular maintenance and replacing.
Further specify below in conjunction with embodiment of the present utility model itself and accompanying drawing.
Fig. 1 is the structural representation sketch of utility model.
As shown in the figure, the utility model is made of a milky white quartz glass tube 3 as oversheath, in order to give liquid central heating and quartz ampoule centrally connected power supply, and be convenient to later maintenance, with the port of electric power incoming line binding post 1 and ceramic insulation cap 2 designs at quartz ampoule, and another end is made termination process, and quartz ampoule just can be in the overhead mode like this, one or more is installed on the heating container side by side, promptly vertically installs.Quartz ampoule diameter, wall thickness and length are selected for use according to the power of electric adding system.Be fixed with coiling in the quartz ampoule and send out the stay pipe 5 of thermal resistance wire 6, on stay pipe 5 outer walls asbestos lining 7 is arranged, guaranteeing to send out thermal resistance wire 6 can firmly be around on the stay pipe.In quartzy stay pipe, be filled with buffering filler 8.
In order to guarantee that operate as normal under good insulation performance and the high temperature is arranged between the conductor, adopt the insulator cap of the ceramic insulating power supply inlet wire of making.
Quartz glass tube is empty in the heating process burns in order to avoid, and quartz ampoule electric power incoming line ceramic insulation cap design down is divided into hot zone and non-hot zone 9 with thermal insulation board 4 with it, and non-hot zone 9 length are 300～350mm.The hot zone is in is heated in the liquid, and the quartz ampoule part sky of avoiding not being in the heating liquid burns, consumes energy.
Claims (3)
1, a kind of quartz glass liquid electric heating tube, constitute by a quartz glass tube (3), there is a coiling on it to send out thermal resistance wire (6) stay pipe (5) in the pipe, it is characterized in that: quartz glass tube (3) inner chamber is divided into non-hot zone (9) and hot zone up and down two partly by a thermal insulation board (4), and the stay pipe that thermal resistance wire is sent out in coiling is positioned at the hot zone of hypomere and is supported by the buffering filler (8) of bottom.
2, electric heating tube according to claim 1 is characterized in that: between a thermal resistance wire and stay pipe asbestos lining (7) is arranged.
