A coal gangue brick drying equipment

Abstract

The invention relates to the field of drying of coal gangue green bricks, in particular to coal gangue green brick drying equipment. The coal gangue green brick drying equipment comprises an outer rack; a drying chamber is installed inside the outer rack; a carrying box is arranged inside the drying chamber; the top of the drying box is provided with an air inlet; the outer wall of the drying chamber is provided with a heat exchange chamber; the edge of an inner frame of the outer rack is provided with a supporting horizontal frame; a heat exchange tube is installed on the supporting horizontal frame; the heat exchange tube is spirally installed on the supporting horizontal frame; the heat exchange tube is inserted into the heat exchange chamber and is attached to the outer wall of the carrying box; the bottom of the drying chamber is provided with a moisture discharging chamber; an exhaust end is installed at the bottom end of the moisture discharging chamber; the side of the exhaustend is connected with a pressurization tube; and a drying box is installed at the bottom of the outer rack. The coal gangue green brick drying equipment provided by the invention achieves a three-dimensional drying effect from inside to outside and increases the flowing speed by quickening flow-in of hot air flow.

Description

technical field [0001] The invention relates to the field of drying coal gangue bricks, in particular to drying equipment for coal gangue bricks. Background technique [0002] Brick drying is the process of using hot air to remove the absorbed water in the brick body. When drying, the temperature should be moderate, generally controlled at about 120 degrees Celsius. If the temperature is too high, it will easily cause the body to dehydrate too quickly and cause cracks; if the temperature is too low, If the dehydration of the green body is too slow, the output will be affected. The dehydration of the green body should be stable, and the high-temperature water vapor in the kiln whose air humidity is close to saturation should be discharged in time through ventilation and drying, so as to prevent the bricks from absorbing moisture and collapsing. Therefore, the drying of coal gangue bricks directly affects coal production. The quality and output of gangue bricks. [0003] At p...

Problems solved by technology

However, at present, the air ducts of the drying kiln are all fixed, which cannot be flexibly adjusted according to the quantity and position of the piled gangue bricks, and the hot air mainly contacts the outer surface of the bricks, and the hollow part of the bricks cannot fully contact with the hot air, resulting in heat in the kiln. Insufficient use of air, high energy consumption, low efficiency, and high economic costs

[0004] Chinese patent (authorized announcement number: CN105486057B) discloses a coal gangue brick drying device, the hot air of the device can take away moisture from the inner surface and the outer surface of the coal gangue brick, so that the coal gangue brick is dried more thoroughly, but the There are also certain technical defects in the patent. The patent cannot bring wet and cold air in time, so that the drying rate of coal gangue bricks near the wet and cold air area is low.
