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 bric...

Embodiment 1

[0041] Embodiment 1: see figure 1 , figure 2 , image 3 and Figure 4 , this embodiment provides a multifunctional tunnel kiln drying equipment, including a drying chamber 16, a first air supply duct 1 above the drying chamber, a first blower 2, and a second exhaust fan arranged at the lower left of the drying chamber 11 and the second moisture exhaust pipeline 12, the air inlet of the first air supply pipeline 1 communicates with the hot air outlet of the tunnel kiln, the air outlet is arranged on the upper part of the drying chamber cavity, the air inlet of the second moisture exhaust pipeline 12 is connected with the second The air outlet of the suction fan 11 is connected, and the air outlet is arranged on the outside of the drying chamber 16 .

[0042] Specifically, the air inlet of the first air supply pipe can also be connected to the air outlet of the desulfurization and dust removal tower, and the tunnel kiln hot air outlet is connected with the air inlet of the d...

Embodiment 2

[0061] Example 2: see Figure 5 , on the basis of the multifunctional tunnel kiln drying equipment provided in Example 1, this embodiment provides a process for making sintered bricks by using the multifunctional tunnel kiln drying equipment for multiple drying and firing, including the following steps.

[0062] a) The adobes after passing through the strip cutting and blank cutting machine enter the automatic adobe stacking machine 27 respectively, and the adobes are stacked on the kiln car 22 of the third auxiliary road 26 by the automatic adobe stacker 27 .

[0063] Specifically, the work of stacking bricks on the kiln car is not limited to stacking with the automatic stacking machine, but can also be stacked manually. The bricks stacked this time are low-level wet bricks, and the number of bricks is generally about 8 layers.

[0064] b) The kiln car 22 walks to the left along the third auxiliary road 26 to the drying chamber 16 for low-temperature drying.

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...
