Embodiment 1

[0023] Such as figure 1 As shown, a brick kiln for firing coal gangue bricks is mainly composed of a firing furnace, a fuel control device and a waste heat collection device; the firing furnace is mainly composed of a gas booster 1, a gas inlet 2, and a kiln 4 , an air inlet 9, a blower 10, a burner 11, a gas valve 12, and an air valve 13; the kiln 4 is a cuboid hollow structure, the furnace wall of the kiln 4 has two layers, and a hollow flue is between the inner and outer layers; The burner 11 is arranged on the bottom of the kiln 4, and the flame nozzle of the burner 11 is arranged on the inside of the kiln 4, and the burner 11 passes through the furnace wall and is the same as the outside, and the burner 11 has two air inlets, and the burner 11 One air inlet is connected with gas valve 12, another air inlet of burner 11 is connected with air valve 13; The gas outlets are connected; the gas supercharger 1 is provided with a gas inlet 2 , and the blower 10 is provided with ...

Embodiment 2

[0030] On the basis of Example 1, this embodiment discloses a preferred structure of a brick kiln for firing gangue bricks, such as figure 1 As shown, the temperature sensor 14 is an optical temperature sensor. The optical temperature sensor can detect the temperature inside the kiln according to the infrared light emitted from the inside of the kiln.

[0031] Further, an air filter device is arranged on the air inlet 9 . The air filter device can reduce the dust entering the air inside the pipeline and improve the stability of the equipment.

[0032] Further, the gas valve 12 and the air valve 13 are electromagnetic brake valves. The solenoid valve can be controlled by the power supply, and the response is fast, which can improve the stability of the system. Other parts of this embodiment are the same as those of Embodiment 1, and will not be repeated here.

Abstract

The invention discloses a brick kiln for firing coal gangue bricks, mainly comprising a fuel gas booster (1), a fuel gas inlet (2), a control system (3), a kiln (4), an exhaust opening (5), a water inlet (6), a water outlet (7), an afterheat collector (8), an air inlet (9), a fan (10), a nozzle (11), a gas valve (12), an air valve (13) and a temperature sensor (14). Through arranging a heat circulation channel in the kiln wall, the coal gangue bricks can be rapidly processed, the energy source is fully utilized and the economic benefit is improved. Through arranging the brick kiln, temperature of the kiln can be accurately controlled, the product quality is improved, and product quality stability is guaranteed; besides, the afterheat can be fully used and the economic benefit is improved.

Description

technical field [0001] The invention relates to the field of gangue bricks and the field of machinery, in particular to a brick kiln for firing gangue bricks. Background technique [0002] The main component of gangue bricks is gangue. Coal gangue is solid waste discharged during the coal mining process and coal washing process. Its main components are Al2O3 and SiO2, and it also contains varying amounts of Fe2O3, MgO, Na2O, K2O, P2O5, SO3 and trace rare elements. The production cost of using coal gangue to produce coal gangue bricks is lower than that of ordinary clay bricks. Using coal gangue to make bricks not only saves land, but also consumes waste from mines. It is a low-carbon building material that is conducive to environmental protection. A mixer is a machine with a bladed shaft that rotates in a cylinder or a tank to stir and mix various raw materials to make it a mixture or a suitable consistency. In the process of traditional gangue brick processing, gangue bri...
