Drying passage for external tile roller kiln

Abstract

The invention provides a drying passage for an external tile roller kiln. The drying passage has one layer, and the bottom of the drying passage is provided with an air distributor; the air distributor is communicated with a heat supply main pipe through a communicating pipe; an air distribution valve is arranged between the communicated air distributor and the communicating pipe; the side wall of the drying passage positioned above a roller is provided with a dehumidifying port; the dehumidifying port is connected on a dehumidifying main pipe through a dehumidifying pipe; the dehumidifying main pipe is connected with a dehumidifying fan positioned on the outer side of the drying passage; and a dehumidifying chimney is arranged at the outlet of the dehumidifying fan. The drying passage has the advantages of reasonable structure, yield increment, loss reduction, energy conservation, emission reduction and reduction of management cost and labor cost.

Description

Technical field: [0001] The invention relates to the technical field of kilns, in particular to a drying channel for a roller kiln for exterior wall bricks. Background technique: [0002] At present, domestic small-sized ceramic exterior wall tiles, such as: 45mmx95mm, 95mmx95mm and other specifications, in the production process, there is a process to dry the body of ceramic exterior wall tiles. Common drying equipment includes 1-3 layers of dryers, using small rollers Generally, the diameter of the roller is about φ30~φ35mm, and the roller distance is about 40~45mm. Due to the small roller, small load capacity and poor bending strength, the dryer should not be too wide or too long. If the dryer is too wide, the rollers will be bent, and the adobes will not run neatly, resulting in messy adobes, which will be difficult to handle in the subsequent process, and the drying loss of the product will be large. Similarly, if the dryer is too long, the adobe will run to the back ...

AI Technical Summary

Problems solved by technology

If the dryer is too wide, the rollers will be bent, and the adobes will not run neatly, resulting in messy adobes, which will be difficult to handle in the subsequent process, and the drying loss of the product will be large

Similarly, if the dryer is too long, the adobe will run to the back stage, which will aggravate the messy state of the adobe and seriously affect the subsequent process.

Therefore, this kind of dryer limits the output increase of the production line, and is the bottleneck of the output of ceramic manufacturers.

In addition, due to the limitation of the roller distance and the roller bar, this dryer cannot produce ceramic exterior wall tiles with smaller specifications, such as 45mmx45mm

In addition, due to the limitation of the roller distance, the green body is easy to fall in the dryer during operation, which increases the drying loss rate of the product
