Technical Field

The invention relates to the field of building material equipment, in particular to a shale brick sintering roller kiln.

Background

Shale brick refers to a brick which is fired at high temperature by using shale and coal gangue as raw materials. The standard requires intensity levels of MU30, MU25, MU20, MU15, and MU 10. When the brick is used as a building main body material, the radionuclide limit of the brick is in accordance with the regulation of GB6566-2001 building material radionuclide limit.

Most of the shale bricks at present are stacked once, then pushed into a kiln for sintering, and then opened and taken out after sintering is finished, the sintering process is discontinuous, the streamlined continuous sintering cannot be realized, and the production efficiency is low.

The invention aims to provide a shale brick sintering roller kiln capable of continuously sintering, thereby solving the problems.

In order to achieve the purpose, the invention discloses a shale brick sintering roller kiln which comprises a kiln body, wherein a sintering channel is arranged in the kiln body, a fireproof conveying roller used for conveying and placing a shale brick supporting plate is arranged at the bottom of the sintering channel, gate valves are arranged on two sides of the sintering channel of the kiln body, a heater is arranged on the outer side of the sintering channel in the kiln body, a feeding platform is arranged at the input end of the sintering channel, and a discharging platform is arranged at the output end of the sintering channel.

Furthermore, the sintering channel extends towards two sides of the furnace body to form an extension channel, and the gate valve is installed at the end part of the extension channel.

Furthermore, the fireproof conveying roller device further comprises a driving motor, wherein the driving motor is installed on the feeding platform or the discharging platform and is in synchronous transmission with the fireproof conveying roller.

Furthermore, the fire-resistant conveying roller is positioned outside the furnace body and is provided with a chain wheel, the adjacent chain wheels are in transmission connection through a chain, and the driving motor is in transmission connection with the chain wheel at the end part of the sintering channel.

Furthermore, the furnace body is provided with an exhaust hole, and a gravity sealing cover is sleeved on the exhaust hole.

Compared with the prior art, the invention has the advantages that:

the invention adopts a tunnel type hearth structure, thereby realizing the continuous flow hydration sintering production of the shale brick, realizing the automatic production of the shale brick and greatly improving the sintering efficiency of the shale brick.
