Abstract

The utility model discloses a microwave sintering box which comprises a box body and a base plate, wherein the box body is matched with the base plate, a wave absorbing layer is arranged on the cavity wall of the box body, and an observation hole is arranged at the top of the box body. The microwave sintering box has a simple structure and is convenient to use.

Description

A kind of microwave sintering box

Technical field

The utility model relates to micro-wave oven, particularly a kind of microwave sintering box.

Background technology

Existing household microwave oven generally is used in cooking food in the family kitchen, but is used in burning glass or ceramic process small sample seldom; Because household microwave oven is at cooking food when design, serviceability temperature is no more than 300 ℃; And burning glass or ceramic process small sample then need 800 ℃ to 1200 ℃ high temperature, directly can not bear so high temperature with little stove at all.Traditional burning glass or ceramic small sample are to fire in the kiln of electric furnace or special use, and the furnace heating-up time of electric furnace, special use is long, and power consumption is big.The utility model uses the high temperature resistant heat insulation material ceramic fibre and the resistant to elevated temperatures absorbing material carborundum of high-quality reasonably to make up, and solves burning glass or ceramic process small sample in the family expenses micro-wave oven easily.

Summary of the invention

Long in order to solve the special-purpose kiln heating-up time of existing electric furnace, the big problem that consumes energy, the utility model provides a kind of microwave sintering box, can be in the family expenses micro-wave oven burning glass or ceramic process small sample.

The technical solution of the utility model is as follows:

A kind of microwave sintering box, described microwave sintering box comprises box body and backing plate two parts; Described box body matches with described backing plate, and the internal chamber wall of described box body is provided with one deck and inhales the ripple layer, and the top of described box body offers a peep hole.

Further, the thickness of described suction ripple layer is 1-1.5mm.

The technique effect that technique scheme reaches is as follows:

The chamber wall of microwave penetration sintering box, microwave is transformed into heat on the microwave absorbing material of internal chamber wall, make cavity temperature rising in the microwave sintering box, and the chamber wall of microwave sintering box is heat insulation, resistant to elevated temperatures, the interior cavity temperature of microwave sintering box is constantly raise, reach the temperature of burning glass or pottery.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Referring to Fig. 1, a kind of microwave sintering box 100 of the utility model comprises box body 101, backing plate 102.

Box body 101 is cylindrical, and its inside is provided with a heating chamber 103, and box body is made by ceramic fibre wet method vacuum forming method, and quality is even, and unit weight is little, and thermal capacitance is little, and thermal conductivity factor is low, and heat-proof quality is good, and is high temperature resistant, and microwave penetration power is strong, does not absorb microwave.

Referring to Fig. 2, the inwall of heating chamber 103 is provided with one deck and inhales ripple layer 104.This suction ripple layer 104 by one deck absorb microwave very strong, resistant to elevated temperatures absorption microwave material coating processing forms; The material that absorbs microwave is carborundum or zirconia, and its effect is to absorb microwave, and microwave is changed into heat, makes cavity temperature rising in the microwave sintering box.

Referring to Fig. 3, the utility model is provided with peep hole 105 at the top of box body, is used for observing the state that article are fired in the box body the inside.

Referring to Fig. 2 and Fig. 4, backing plate 102 matches with box body 101, is circular (as shown in Figure 5), and it is provided with one and is used to place the boss 106 of waiting to fire thing, and boss 106 matches with heating chamber 103 on the box body 101.

The operation principle of microwave sintering box of the present utility model is: the chamber wall of microwave penetration sintering box, microwave is transformed into heat on the microwave absorbing material of internal chamber wall, make cavity temperature rising in the microwave sintering box, and the chamber wall of microwave sintering box is heat insulation, resistant to elevated temperatures, the interior cavity temperature of microwave sintering box is constantly raise, reach the temperature of burning glass or pottery.

Based on such scheme, concrete enforcement of the present utility model is as follows:

Embodiment 1:

Microwave sintering box 100, backing plate 102 is selected the high-quality ceramic fibre for use, and making beating, batching, mould vacuum forming, oven dry, high temperature are removed organic matter.With 200 purpose carborundum powders and an amount of inorganic binder furnishing pasty state, inorganic binder can be selected Ludox, aluminium colloidal sol, aluminum phosphate, sodium metasilicate etc. for use; The carborundum of pasty state is brushed to microwave sintering box inwall, and THICKNESS CONTROL is 1---1.5mm, and oven dry.

As shown in Figure 6, the utility model is put into glass small sample 107 on backing plate 102 boss 106 in use, covers box body 101; Together put into the micro-wave oven that power is 800w together with backing plate 102, small sample 107, box body 101, microwave power is transferred to maximum, start micro-wave oven, after 3 minutes, cavity temperature rises to 800 in the microwave sintering box 100---900 ℃, glass small sample 107 can be baked under this temperature, and microwave sintering box 100 outside wall temperatures are no more than 40 ℃, can directly backing plate 102 and box body 101 be taken out outside the micro-wave oven with hand fully under this temperature, after the cooling, sample bakes naturally.
