Multifunctional tunnel kiln type drying device and process by utilizing same for repeatedly drying and palletizing burning to manufacture sintered bricks

Abstract

The invention provides a multifunctional tunnel kiln type drying device. The device comprises a drying chamber (16), a first air supply pipeline (1), a first air blower (2), a second exhaust fan (11)and a second moisture removal pipeline (12); the multifunctional tunnel kiln type drying device is further characterized by comprising a first exhaust fan (8), a first moisture removal pipeline (9), atelescopic air pipe (13), a movable partition plate (6) with a first opening (14) and an air cylinder (3), wherein an air inlet of the telescopic air pipe (13) communicates with an air outlet of thefirst air supply pipeline (1), an air outlet of the telescopic air pipe (13) communicates with the first opening (14) of the movable partition plate (6), the air cylinder (3) comprises a piston rod (5), one end of the piston rod (5) is fixedly connected with the movable partition plate (6) and is used for driving the movable partition plate to move up and down. According to the device, the structure is simple, wet blank bricks with different heights can be uniformly dried, and the yield of sintered bricks is effectively improved.

Description

technical field [0001] The invention relates to the technical field of sintered brick production, in particular to a multi-functional tunnel kiln drying equipment and a process for making sintered bricks by using the same for multiple times of drying and stacking. Background technique [0002] Tunnel kiln is a modern thermal equipment for continuous firing. It is widely used in the firing production of sintered bricks and other products. The bricks are formed by extrusion, die-cutting, and must be dried before being pushed into the kiln for firing. [0003] At present, sintered brick production enterprises mostly use one-time drying brick firing process. Due to the limitation of the strength of the next wet brick, generally it can only be stacked to a certain height (12 floors), and it cannot continue to stack bricks. This process mainly There are the following disadvantages: first, the efficiency is low, and the requirements for raw materials and brick making machines are r...

Problems solved by technology

[0003] At present, sintered brick production enterprises mostly use one-time drying brick firing process. Due to the limitation of the strength of the next wet brick, generally it can only be stacked to a certain height (12 floors), and it cannot continue to stack bricks. This process mainly There are the following disadvantages: first, the efficiency is low, and the requirements for raw materials and brick making machines are relatively high; second, the output is low, and the green body is prone to serious deformation and even collapse

[0005] Although the above-mentioned process of making sintered bricks by multiple times of dry stacking and firing improves the production efficiency of sintered bricks compared with the process of firing bricks by one dry stacking, this process also has some disadvantages, such as the same drying chamber for wet bricks of different heights. The drying method makes the drying effect of wet adobe bricks of different heights uneven, especially the bottom adobe, which is prone to cracking after secondary drying, which affects the yield of the product. The rate is reduced and the time is longer, which limits the further improvement of the production efficiency of sintered bricks
