Description

Technical Field

[0001] The utility model relates to a pulverized coal burner, in particular to a pulverized coal full combustion device. Background Art

[0002] In the process of lime kiln calcining and producing lime, coal powder needs to be transported and distributed to the burner for combustion to provide heat source for the calcination of lime in the lime kiln. At present, the coal powder transportation and distribution device mainly includes coal powder bin, distributor and coal powder injection device, and the coal powder injection device mainly includes injection pipe and Roots blower.

[0003] However, the existing coal powder full combustion device is easily subjected to impact force when placed, which makes the coal powder full combustion device easily damaged and shortens its service life. In addition, the existing coal powder full combustion device is not provided with a baffle on the coal powder machine, which makes it easy for the coal powder to fly around when poured in, thereby causing unnecessary waste of coal powder.

[0011] Preferably, the lower end of the wind direction tube is connected to a support seat, and a step is provided on one side of the support seat.

[0012] The embodiment of the utility model provides a coal powder full combustion device, which has the following beneficial effects: the coal powder full combustion device can be subjected to impact force when being placed, and the coal powder full combustion device is not easily damaged by the setting of a shock absorber, and the coal powder full combustion device is provided with a baffle on the coal powder machine so that when the coal powder is poured in, the coal powder will not fly around, thereby causing unnecessary waste of the coal powder.

[0013] By setting up the shock absorber, the staff can use a crane to lift the burner onto the fixed plate, and use the setting of the shock absorber of the pulverized coal full combustion device to transmit the generated vibration force downward. It must first pass through the fixed plate to the shock absorber and then be transmitted to the bottom plate. At this time, the shock absorber will dampen the vibration force received, thereby reducing the vibration force received by the bottom plate, reducing the friction between the bottom plate and the ground, and making the pulverized coal full combustion device not easily damaged.
