Description

Technical Field

[0001] The utility model relates to the technical field of gangue brick manufacturing, in particular to a device for quickly drying gangue brick blanks. Background Art

[0002] The main component of gangue bricks is gangue. Gangue is solid waste discharged during coal mining and coal washing. The production cost of gangue bricks is lower than that of ordinary clay bricks. Using gangue to make bricks not only saves land, but also consumes mine waste. It is an environmentally friendly low-carbon building material.

[0003] Gangue brick blanks need to be dried before sintering. Usually, the hot air from the sintering room is sent into the drying room through the hot air channel for drying. At the same time, the exhaust fan of the drying room discharges the humid air inside. However, the hot air channel is usually set at the upper end of the drying room. The density of humid air and hot air is lower than that of normal air. The humid air is concentrated at the upper end of the drying room. The mixed temperature of hot air and humid air is reduced, and the moisture content is increased, resulting in a longer drying time. For this reason, we propose a rapid drying device for gangue brick blanks. Utility Model Content

The output shaft of the motor 75 drives the adjacent rotating shafts and gears 74 to rotate respectively. The gears 74 drive the adjacent rack plates 73 to mesh downward. The slide grooves 72 slide downward on the outside of the adjacent guide rails. The closed door 71 moves downward to contact with the upper surface of the base 1, so that a relatively closed space is formed between the drying room 4 and the closed door 71. The hot air grooves 6 increase the distance between the bottom of the coal gangue brick blank and the ground, reducing the contact between the humid air on the ground surface and the bottom of the coal gangue brick blank. The hot air covers most of the hot air grooves 6, so that the bottom of the coal gangue brick blank can also be fully dried.

[0023] The drying mechanism 2 includes an exhaust duct 21, a hot air duct 1 22, a clamp 23 and a base 24. The upper surface of the base 1 is provided with a base 24, and the base 24 is located inside the drying room 4. The outer wall of the hot air duct 1 22 is fixedly sleeved with uniformly distributed clamps 23, and the lower ends of the clamps 23 are fixedly connected to the upper surface of the base 24. The top wall of the drying room 4 is fixedly connected with the uniformly distributed exhaust duct 21, and the rear side of the drying room 4 is fixedly connected with an air intake duct 3. The upper end of the air intake duct 3 is connected to the hot air channel of the sintering room, and the lower end of the air intake duct 3 is connected to the rear end of the hot air duct 1 22. The drying mechanism 2 also includes a hot air duct 26. The top wall of the drying room 4 is fixedly connected with a uniformly distributed hot air duct 26.

When the fans 25 are started, the humid air inside the drying room 4 is extracted through the evenly distributed exhaust ducts 21. The exhaust ducts 21 are evenly distributed from left to right, and can cover most areas of the drying room 4, so as to more fully extract the humid air. At the same time, the hot air duct 1 22 delivers the hot air from the sintering room into the interior of the drying room 4 through the hot air duct 1 22 and the hot air duct 2 26. The hot air duct 1 22 is located at the lower end of the drying room 4, so that the hot air is distributed throughout the drying room 4. The height of the air outlet of the hot air duct 26 is similar to the height of the air inlet of the exhaust duct 21, so that the hot air contacts the humid air at the air inlet of the exhaust duct 21, so as to thoroughly dry the air.

The output shaft of the motor 75 drives the adjacent rotating shaft and the gear 74 to rotate respectively, and the gear 74 drives the adjacent rack plate 73 to mesh downward, and the slide groove 72 slides downward on the outside of the adjacent guide rail, and the closed door 71 moves downward to contact with the upper surface of the base 1, so that a relatively closed space is formed between the drying room 4 and the closed door 71, and then the fan 25 is started, and the humid air inside the drying room 4 is extracted through the evenly distributed exhaust ducts 21. The exhaust ducts 21 are evenly distributed from left to right and can cover the dry room 4. Most areas of the drying room 4 are convenient for more fully extracting humid air. At the same time, the hot air duct 22 delivers the hot air from the sintering room into the interior of the drying room 4 through the hot air duct 22 and the hot air duct 26. The hot air duct 22 is located at the lower end of the drying room 4, which is convenient for the hot air to spread throughout the entire drying room 4. The outlet height of the hot air duct 26 is similar to the inlet height of the exhaust duct 21, so that the hot air contacts the humid air at the inlet of the exhaust duct 21, which is convenient for thoroughly drying the air. The hot air trough 6 increases the distance between the bottom of the coal gangue brick blank and the ground, reducing the contact between the humid air on the ground surface and the bottom of the coal gangue brick blank. The hot air covers most of the hot air trough 6, so that the bottom of the coal gangue brick blank can also be fully dried.
