Abstract

The utility model relates to a triple heat storage reuse mechanism for a household heat preservation electric furnace, which is an apparatus which is arranged on a heat preservation electric furnace body for preventing heat dissipation. When the electric furnace is operated, stored heat formed by the furnace body can be transferred to the outside through a furnace shell, and the decreasing amplitude of the stored heat of the furnace body is limited by using an aluminum silicate fiber product as a furnace liner. Moreover, the triple heat storage reuse mechanism can effectively solve the problem of stored heat loss of the household heat preservation electric furnace. The triple heat storage reuse mechanism is mainly formed by three heat-insulating materials, namely compact heat-insulating materials, loosened heat-insulating materials and bandgap heat-insulating materials, and a furnace shell the bottom plate of which is provided with holes; the compact heat-insulating materials closely adhere to the inner wall of the furnace shell, and then the resistance to heat flow is large and the heat resistance of a heat flow 'channel' which is formed by granular heat-insulating materials in the furnace body is small, thereby external cold air enters into the furnace from the bottom plate of the furnace shell, absorbs the stored heat, floats upwards and is converted into thermal current after the furnace body is heated, the thermal current can run upwards along the 'channel' and transfer heat to the furnace bottom, consequently realizing direct utilization of the stored heat in the furnace body and reducing the heat loss to the maximum degree.

Description

Family expenses electric mantle heater three material accumulation of heat reuse mechanisms

Affiliated technical field

The utility model relates to a kind of family expenses electric mantle heater three material accumulation of heat reuse mechanisms, and it is arranged on the facility that prevents heat leakage on the family expenses electric mantle heater body of heater.

Technical background

When the family expenses electric mantle heater can heat electric furnace body self in energising by the mode that the conduction and the width of cloth are penetrated during work, make and form accumulation of heat in the body of heater, accumulation of heat can be transmitted heat to the outside by furnace shell again, cause energy loss, in order to reduce this loss, people take to add the mode of thick insulation layer, but the body of heater accumulation of heat also increases thereupon.In recent years, adopt the less aluminum silicate fibre product of thermal capacitance to do heat insulation furnace lining again both at home and abroad, but the amount of decrease to the body of heater accumulation of heat is limited, if develop the littler material of thermal capacitance again, then difficulty is very big, therefore be necessary to open new thinking, the static heat insulation theory that breaks traditions, the heat insulation mode that development makes new advances solve the accumulation of heat loss problem of family expenses electric mantle heater.

Summary of the invention

The utility model provides a kind of family expenses electric mantle heater three material accumulation of heat reuse mechanisms for people, can solve the accumulation of heat loss problem of family expenses electric mantle heater effectively with it, makes the body of heater accumulation of heat obtain direct reuse, reduces heat loss to greatest extent.

The technical scheme of the utility model technical solution problem is: move this objective phenomenon and hot gas come-up principle towards the less direction of resistance easily according to fluid, in body of heater, set out resistance little " passage " that allow the hot-fluid directed flow, body of heater accumulation of heat fluidify, and the accumulation of heat reuse is realized in the guiding the bottom of a pan.The utility model is fine and close heat-barrier material, loose heat-barrier material and particle heat-barrier material by three kinds of heat-barrier materials mainly, and base plate furnace shell with holes constitutes, the hole on the furnace shell can by dash, processing mode such as brill makes.The particle heat-barrier material can be common heat-barrier material, circular or the erose particle of firing as the light-weight refractory clay, the average diameter minimum of particle is not less than 5mm, loose heat-barrier material can adopt aluminosilicate fiber cotton or rock wool etc., fine and close heat-barrier material adopts general fire-resistant heat insulating material, as asbestos---and waterglass fireproof coating, aluminosilicate fiberboard or rock cotton board.Fine and close heat-barrier material is close on inwall all inner surfaces except that plate hole of body of heater, and thickness is not less than 30mm and is advisable.Place a certain amount of loose heat-barrier material on the fine and close heat-barrier material, the light and band gap of this material, reducing thermal capacity, the particle heat-barrier material fills up all the other insulated spaces above the furnace shell bottom plate hole with the fine and close heat-barrier material of its instead of part and particle heat-barrier material.Like this after body of heater is heated, cool exterior air enters in the stove from the furnace shell base plate, absorb the upwards unsteady thermal current that becomes of accumulation of heat, owing to have fine and close heat-barrier material resistance big on the furnace wall, thermal current is difficult for passing through, and the thermal resistance of band gap heat-barrier material is little, and " passage " that thermal current then can form along this space upwards operation passed to the bottom of a pan with heat, thereby realize that the body of heater accumulation of heat directly utilizes, and has reduced heat loss to greatest extent.

The specific embodiment

Accompanying drawing 2 also is an application example of the present utility model, this is one and is provided with family expenses electric mantle heater body of heater of the present utility model, it mainly is drilled with the furnace shell 1 in hole 6 by base plate, thickness is the aluminosilicate fiberboard 2 of 40mm, and average diameter is that high-alumina lightening refractory particle 3, aluminosilicate fiber cotton 8, stone or metal plate for standing a stove on as a precaution against fire with holes 4, the resistance wire 5 of 10mm constitutes.During stove work, resistance wire 5 heatings, after body of heater is heated, the stove outer air enters the upwards unsteady thermal current that becomes of absorption accumulation of heat in the stove by the bottom outlet 6 of furnace shell 1, owing to have the heat insulation resistance of aluminosilicate fiberboard big on the furnace wall, by " passage " upwards operation that little, the most of hot-fluid of hot-fluid then constitutes along the gap of heat-barrier material particle 3, the bottom of a pan is passed to heat in the hole 7 of passing stone or metal plate for standing a stove on as a precaution against fire 4 with holes makes the body of heater accumulation of heat obtain reuse at any time.The thermal efficiency that experimental results show that this mechanism can reach more than 83%, and energy-saving effect obviously is better than the general family expenses electric mantle heater that thermal insulation layer is all clogged with alumina silicate fibre.
