The heating device 102 is arranged above the sintering box 101 and is used for heating the sintering box 101 from top to bottom; and controls the sintering temperature in the sintering box 101 by controlling the heating device 102; the four upper supporting wheels 203 at the upper end are symmetrically arranged on the front side and the rear side, so that the two transmission chains 201 can be supported by matching with the two lower wheel frames, the two transmission chains 201 are positioned in the sintering box 101 and are rectangular, the two transmission chains 201 at the lower end are pushed upwards by the tensioning mechanism, the two transmission chains 201 are kept in a tensioning state, a first motor is arranged on the lower wheel frame at the lower right end, and the lower wheel frames are driven, so that the two transmission chains 201 are driven to slowly rotate;
since the lower end of the sintering box 101 is in an open state, the pressed compact can be placed on a supporting frame positioned at the lower end at the opening of the lower end of the sintering box 101; as the two driving chains 201 slowly rotate, the two driving chains 201 drive the supporting frame to pass through the lower wheel frame at the left end through the transverse shaft 202, and then slowly move upwards, in the process, the temperature of the pressed compact is slowly raised, when the supporting frame moves to the two driving chains 201 between the four upper supporting wheels 203, as the two driving chains 201 are horizontally arranged and positioned at the highest position and are closest to the heating device 102, the temperature of the pressed compact is highest, the pressed compact reaches the sintering temperature in the rising process, and when the pressed compact moves on the two driving chains 201 between the four upper supporting wheels 203, constant-temperature sintering is achieved, after the pressed compact passes through the two upper supporting wheels 203 at the right end, the pressed compact starts to descend along with the driving chains 201, sintering is completed, and after the pressed compact passes through the lower wheel frame at the right end, the pressed compact is slowly lowered, and moves to the opening at the lower end of the sintering box 101, the sintered compact is taken down, and then naturally cooled, and the ceramic material is obtained; thus, the green compacts are sintered continuously in a circulating way, and the sintering efficiency is improved.
As shown in fig. 2-13:
