Description

A kind of block wet billet drying chamber and its manufacturing method

technical field

The invention relates to a block-shaped wet billet drying chamber and a manufacturing method thereof, and belongs to the technical field of building material wet billet drying.

Background technique

At present, in the prior art, the production of bricks and tiles, wall materials, ceramics, refractory materials, etc. often adopts a chamber-type drying room for drying. The traditional chamber-type drying room is a structure with maintenance structures on the side and top, with doors at both ends (or one end), and hot air (or hot flue gas) inlets and humid air outlets on the other sides. When bricks, tiles, wall materials, ceramics, refractory materials and other products are formed, they are often made into block-shaped wet billets containing a certain amount of water, and then pushed into the chamber-type drying room with a trolley, and manually stacked in the drying room. , After the drying chamber is full, close the door of the drying chamber, send hot air into the drying chamber through the main heating air duct, and the hot air evaporates the water in the wet billet, so that the wet billet is gradually dried to the required moisture content to obtain a dry billet. After the wet billet is dried, open the door of the drying chamber, manually put the dry billet on the trolley, and push it out of the drying room, and the whole drying process ends. The chamber-type drying chambers in the prior art generally adopt an independent structure. In this independent structure, each drying chamber is set independently, and the hot air from the main heat supply duct is directly input into a single drying chamber. To dry block-shaped wet billets, this independent structure of the drying chamber not only has the problem of high energy consumption, but also has the problems of large footprint, high production cost, and difficulty in automatic control; in addition, in the prior art The drying room directly discharges the moisture in the room to the outside through the ventilation hole set in the drying room and communicates with the outside world. This natural moisture drainage method not only wastes energy, but also has a certain impact on the drying quality and the environment. ; In addition, in the existing drying room, the uniform distribution of the drying medium mainly depends on the axial flow fan and the rotating air distributor installed in the drying room. Because the working environment in the drying room is humid and the sulfur content is high, the drying room These devices are very vulnerable to damage. So the use effect of existing massive wet billet drying chamber is still not ideal enough.
