In the present invention, the stirring member 8 is connected to the inner surface of the first screen box 44, the second screen box 45 and the third screen box 46 by rotation, and the first screen box 44, the second screen box 45 and the third screen box 46 are in the During the reciprocating motion, the gas-coal is driven to collide with the stirring member 8. During the shaking of the gas-coal, the stirring member 8 can further stir the shaking gas-coal, so that the gas-coal is heated more uniformly.

Since tar will be produced when gas coal is coking, the present invention has a third through hole 441 at the bottom of the first screen box 44, the second screen box 45 and the third screen box 46, so that the No. The tar in the screen box 45 and the third screen box 46 flows out in time.

In the present invention, by making the structures of the No. 1 moving plate 41 and the No. 2 moving plate 42 into a hollow structure, when the gas coal in the No. 1 sieve box 44 and the No. 2 sieve box 45 falls, they can be removed from the No. 1 moving plate 41 respectively. And the hollow part of the No. 2 moving plate 42 is directly dropped into the No. 2 screen box 45 and the No. 3 screen box 46 for screening, so as to achieve the effect of rapid screening.

Since the working temperature of the present invention is 500°C-1000°C, the materials of the sieve moving assembly 4, the power assembly 5, the round rod 6, the balance block 7 and the stirring member 8 in the present invention are high temperature resistant materials, such as high-speed steel, 3Cr2W8V, 5CrNiMo, 5CrMnMo, etc., so that it can move normally.

The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above-mentioned embodiments. The above-mentioned embodiments and descriptions only illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will also have Various changes and modifications fall within the scope of the claimed invention. The claimed scope of the present invention is defined by the appended claims and their equivalents.
