Abstract
The utility model belongs to the high temperature experiment furnace specially used for laboratories of the cement industry. The utility model comprises a furnace body, a heating element and a temperature controlling box. The utility model is characterized in that the furnace body adopts a double-layer furnace structure which is composed of an inner furnace and an outer furnace. Besides, the utility model is provided with double layer furnace doors. The inner furnace is composed of a hearth formed by that a steel plate is coated on heat insulation and refractory materials and the heating element in the hearth. The outer furnace is formed by that the heat insulation material is filled in steel plates, and the inside of the inner layer of steel plate is provided with a heat insulation plate in an inlaid way. A thermocouple connected with a digital display thermometer of the temperature controlling box is penetrated into the hearth of the furnace. Both the inner furnace door and the outer furnace door are formed by that the interiors of steel plates are filled with the heat insulation material. The utility model has the advantages of time saving, electricity saving, accurate temperature control, favorable heat insulation and convenient use and maintenance.
Description
The utility model relates to the high temperature experimental furnace of a kind of cement industry laboratory special use, is to the improvement of current experiments chamber with stove.
At present, the high temperature experimental furnace that generally uses of cement industry still is traditional electric furnace of making heater element of electric furnace heating wire.Because the insulation material, refractory material, heating element heater and the structure thereof that adopt are unreasonable, and its service efficiency is reduced greatly, waste energy maintenance difficult.In addition, because the heating-up time is long, the body of heater external temperature is too high, and operating ambient temperature is raise, and brings inconvenience to the operator.
The purpose of this utility model is that a kind of selection of development is reasonable, good heat insulating, and thermal efficiency height, cement high temperature experimental furnace easy to maintenance is to solve above shortcomings in the prior art.
The utility model comprises body of heater, heating element heater, temperature control case.Be characterized in that body of heater adopts the double-deck furnace structure that is made of interior stove, outer stove, and be provided with Bilayer oven door.Burner hearth that interior stove is made by steel plate bag insulation, refractory material and the heater element in the burner hearth constitute.Outer stove is by filled heat insulating material in the steel plate, constitute at the inboard insert warming plate of inner layer steel plate.The thermocouple that is connected with the digital display temperature meter of temperature control box penetrates in the burner hearth of this stove.Inside and outside fire door constitutes by filled heat insulating material in the steel plate.Better heat preservation like this.
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is circuit theory diagrams of the present utility model;
Body of heater of the present utility model adopts the double-layer furnace body that is made of interior stove, outer stove.Interior stove is steel plate 6 an inwalls edge no stone calcium silicate heat-preserving plate 5 (this warming plate maximum temperature can be anti-1050 ℃, and heat insulation effect is good), warming plate 5 interior burner hearths 7 by alumina cement and the xoncrete structure that Gu is expected, spheroidal graphite powder refractory material is made.Heater element is set in the burner hearth---silicon carbide rod 10.Laying heat-conducting plate 9 on heater element silicon carbide rod 10.Heat-conducting plate 9 selects for use quartz glass plate to get final product.Outer stove does not have stone calcium silicate heat-preserving plate 5 by filling varicosity perlite in the double-layer plate 2 or sole of the foot stone flours 3 at the inboard insert of inner layer steel plate, and scribbles insulation glue carry out adhering and sealing between steel plate and warming plate, and heat can not be seen through between the slave plate seam.Outer fire door 1 is made of filling varicosity insulation material in the steel plate (perlite or sole of the foot stone flour).Interior fire door 4 is made of steel plate bag varicosity insulation material and interior edge refractory material.Be convenient for maintaining, interior stove and outside be provided with track 11 between the stove, only need during maintenance pull out interior stove, push after having repaiied and get final product.Temperature control box of the present utility model mainly is to adopt noncontacting switch controllable silicon and digital display temperature meter T to control furnace temperature.R is a heater element silicon carbide rod 10, and DR is a thermocouple 8, and XD is an indicator lamp, and TK is the digital display temperature meter switch, and 1RD, 2RD are fuse, and DK is a knife-like switch.
The utility model is worked as general shape and is of a size of 550 * 575 * 550 (mm), insulation layer thickness is 160mm, size of burner hearth is 220 * 180 * 100 (mm), heating element heater is 4 silicon carbide rods, rated power is 4KW, supply voltage is 220V, and the furnace temperature adjustable range is (0--1000) ℃, and temperature control box is of a size of 330 * 260 * 180 (mm).
The used high-temperature experimental furnace of the utility model--cement high temperature experiment furnance and existing cement industry is compared has following advantage:
1, from furnace binding, this stove is inside and outside double-deck furnace structure, and is provided with bilayer Fire door, heat leakage is little, and high efficiency, crust temperature only have 40 ℃, use than existing Experimental furnace crust temperature low about 30 ℃.
2, use stretched formula silicon carbide rod to do heater element, do heater element than resistance wire Thermal efficiency height. Same rated power 4KW electric furnace is warmed up to 1000 ℃, and this practicality is new Type only needs 25 minutes, needs 2.5--3 hour and the existing electric furnace that uses is minimum, and this greatly Saved the energy.
3, the control of thyristor controlled digital display temperature meter is partly adopted in temperature control, thereby makes temperature control device more perfect, has easy to adjustly, and temperature control is accurate, advantages such as noiselessness.
In sum, the utlity model has save time, power saving, temperature control be accurate, rational in infrastructure, insulation is good, is convenient to characteristics such as maintenance, is the renewal product of present cement industry laboratory usefulness high temperature experimental furnace.
