Production line for automatically producing perforated bricks

Abstract

The invention discloses a production line for automatically producing perforated bricks. The production line comprises a shale screening device (1), a stirrer (2), a perforated brick extrusion forming machine (3), a perforated brick cutting machine (4), a machine (5) for arranging the perforated bricks in order, a drying device (6) and a calcination device (7). A feed pipe (22) of the stirrer (2) is connected with a discharge port (16) of the shale screening device (1), a rack A and a rack E are spliced, a rack B and a rack F are spliced, a discharge pipe (25) of the stirrer (2) is connected with the inlet end of the perforated brick extrusion forming machine (3), the outlet end of the perforated brick extrusion forming machine (3) is arranged above a flat plate (30) and located between two vertical plates (33), and the drying device (6) is communicated with the calcination device (7). The production line has the advantages that the screening efficiency is improved, shale and water are fully mixed, notches are flat, the cutting efficiency is high, and the perforated bricks can be conveyed into the drying device in order.

Description

technical field [0001] The invention relates to the technical field of porous brick production, in particular to a production line for automatically producing porous bricks. Background technique [0002] At present, with the continuous development of the city, high-rise buildings have sprung up, and the consumables used to construct the non-load-bearing walls of the buildings are mainly porous bricks. The porous bricks replace the solid bricks, which reduces the cost of building non-load-bearing walls, and Reduced construction time for erecting non-load bearing walls. The main material of the porous brick is shale on the mountain. The existing processing technology is: first crush the large shale into small-sized shale in the crusher, and then screen out the shale with a particle size of 2~3mm. Then shale with a particle size of 2~3mm is mixed with water and binder in a mixing mixer to increase the viscosity. After mixing, the material is sent to a porous brick extrusion mo...

AI Technical Summary

Problems solved by technology

However, the existing equipment for producing porous bricks has a complex structure, and it is difficult to achieve continuous production of porous bricks, which greatly reduces the production efficiency and product qualification rate of porous bricks. The extrusion molding machine cannot ensure the dimensional accuracy and surface quality of the blank, the manual coding of blanks leads to a significant increase in workload and scrap rate, the natural drying before roasting greatly prolongs the production cycle, the traditional tunnel kiln roasting technology causes atmospheric acid pollution, and the finished bricks are damaged. Manual stacking leads to difficulties in loading and unloading trucks and untidy stacking, etc. Therefore, the low-efficiency and backward existing brick and tile production line technology and the high-efficiency and environmental protection industry development needs have become the main contradictions that need to be resolved in the brick and tile field.
