Technical Field
[0001] The utility model relates to the technical field of burners, in particular to a particle fuel conveying device. Background Art
[0002] A burner is a device that mixes fuel and air and burns them after being ejected in a certain way. Biomass pellet burners use biomass pellets as fuel and are widely used in various thermal energy industries such as boilers, die-casting machines, industrial kilns, incinerators, and smelting furnaces. They have the advantages of obvious environmental benefits and low operating costs. During the delivery of biomass pellet fuel, it is necessary to open the fuel bin door, use a trolley or other tool to move the hopper to dump the biomass pellet fuel into the fuel bin of the burner, and close the fuel bin door after the dumping is completed. Since the hopper is at a certain height from the bottom of the fuel bin, fine fuel particles will be raised during the dumping process, polluting the working environment and being detrimental to the health of the operators.

[0015] By adopting the above technical solution, the mobile driving cylinder can be arranged at a higher position, away from the fuel bin, so as to reduce the contact and adhesion of the particle fuel to the mobile driving cylinder.
[0016] The utility model is further configured as follows: the lifting seat is provided with a slide groove, the slide seat is slidably connected to the slide groove, and the slide groove penetrates the lifting seat from top to bottom.
