Background
The four-channel pulverized coal burner is literally understood to be four channels which are respectively a central air channel, a pulverized coal channel or a coal gas channel, a rotational flow air channel and an outer air channel from inside to outside. The working principle is as follows: pulverized coal is blown into the kiln by the pulverized coal blowing fan, the flame thickness is adjusted by the shrinkage of the central air pipe (the central air pipe is generally adjustable and has a certain expansion amount), and the pulverized coal is scattered by the rotational flow air in a certain direction in a rotating manner, so that the pulverized coal is atomized and fully combusted. In the production process, because the raw coal contains light impurities such as plastic bags, fibrofelt, plastic bottle crushed shells, thin iron sheets and the like, the impurities enter a coal mill along with a raw coal belt to be ground, part of the light impurities enter a coal dust bin and then enter a burner coal dust channel under the driving of coal air, and part of the impurities cannot be deposited on the inner wall of the channel through the coal dust channel. Along with the increase of the operation time, sundries are deposited more and more, so that the direction of coal wind is changed, the abrasion of a channel is increased, and the abrasion is serious. The burner is damaged and cannot be used, and the burner can only be shut down and returned to a factory for maintenance. The maintenance cost is high, the time consumption is long, and major equipment accidents and process accidents are caused. The coal air channel is cleared and blocked every two months on average, the inner wall of the coal air channel is seriously abraded, the coal air channel needs to be returned to a factory for maintenance every two years, the maintenance cost is about 20 ten thousand yuan, and the production cost is greatly increased.
SUMMERY OF THE UTILITY MODEL

Furthermore, the diameters of the air inlet and the air outlet are the same, the cross section through which the pulverized coal passes is a right-angled triangle, and the air inlet and the air outlet are both positioned on the same right-angled side line of the right-angled triangle.
Furthermore, the spacing between the grate bars of the filtering grate is 0.8-1.2cm.
Furthermore, a cleaning door is rotatably arranged at the bottommost part of the pulverized coal conveying pipe and is closed through a bolt.
Furthermore, the filtering grate is obliquely arranged towards the air inlet.
Furthermore, the vibration mechanism comprises a vibration ball, a connecting rope is fixed on the vibration ball, and the free end of the connecting rope is fixedly connected with the filtering grate.
Further, vibrations ball diameter is 10cm, it is half of vibrations ball diameter to connect rope length, it adopts the nylon material to connect the rope.
