Description

[0002] Combustion equipment is an energy conversion device. Fuel containing energy is input into the combustion equipment, and the combustion equipment outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. Existing combustion equipment usually uses coal as fuel. After the fuel is lifted by a spiral elevator, the fuel is put into the combustion equipment. Some factories use biomass fuel, but biomass fuel is prone to incomplete combustion and low energy conversion rate.

[0064] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0091] The vibration motor 310 is disposed at the end of the vibration plate 36 away from the upper cylinder 12 , and is used to drive the vibration plate 36 to swing around the first fixed axis 37 and drive the material to fall into the upper cylinder 12 .

[0092] like Figures 2 to 6 As shown, after starting the vibration motor 310, the oscillation plate 36 swings around the first fixed axis 37, and the jumping axis 38 at the other end of the oscillation plate 36 will move back and forth in the limit groove 39, ensuring that the oscillation plate 36 will not separate from the scraper 34 while vibrating, and it is also convenient for the fuel to fall into the upper cylinder 12; optionally, a scraper 35 is provided on the edge of the scraper 34, and the scraper 35 extends along the inner wall curved surface of the mixing cylinder 31, so that when the scraper 34 rotates, the scraper 35 can better scrape the fuel accumulated on the inner wall of the mixing cylinder 31, so that more fuel falls onto the oscillation plate 36, thereby facilitating more fuel to be discharged outward.

[0093] In some embodiments, when the oscillation plate 36 is located above the spiral conveying rod 4 and the normal direction is perpendicular to the second direction, the oscillation plate 36 has a second angle with the first direction, and the second angle opens toward the inlet side;

[0094] like Figure 3As shown, the above-mentioned oscillation plate 36 is rotated to the top of the second conveying rod 42. Since the second angle opening is toward the inlet side, that is, the oscillation plate 36 is tilted downward toward the outlet side, even if the vibration motor 310 is not started, part of the fuel can fall along the oscillation plate 36 to the upper cylinder 12 on the right side.

Further, a first through hole 311 is provided on the blocking disk 33 for the rod body of the second conveying rod 42 to pass through, and a second through hole 312 is provided on the cylinder body for the spiral leaf of the second conveying rod 42 to pass through.

[0099] refer to Figure 2 During assembly, the second conveying rod 42 is inserted into the second through hole 312 from the barrel body, and then the scraper 34 of the oscillating part is pushed upward along the installation long groove 64, and then the internal thread ring 66 cooperates with the external thread 65 to make one end of the internal thread ring 66 abut against one end of each scraper 34, and the other end of each scraper 34 abuts against the inner wall of the installation long groove 64 to achieve the installation of the scraper 34 and other components, and then the blocking plate 33 is installed to make the rod body of the second conveying rod 42 pass through the first through hole 311, and then the first conveying rod 41 is installed to the bottom of the second conveying rod 42 through the matching connection of the card groove 61, the card block 62 and the installation through hole 63, and finally the lower barrel 11 is tilted and sleeved from bottom to top on the outside of the first conveying rod 41, and finally the assembly of the stirring mechanism 3 is completed, which is convenient for disassembly, transportation, maintenance and replacement of parts.

[0103] like Figure 2 , Figure 3 and Figure 7 As shown, the first conveying rod 41 delivers the fuel inside the lower cylinder 11 from the first discharge port 51, and the delivered fuel will fall into the cover box 52 and fall onto the annular block group in the outermost circle. The annular block group will rotate with the rotating disk 55, so that all the fuel passes through the staggered material channels 57 and is crushed for the second time by the cutting knife 59 between the annular block groups, thereby reducing large particles in the fuel and making the fuel burn more fully; the crushed fuel will rotate with the annular blocks 56 and the rotating disk 55, so that the fuel will fall onto the arc plate 54 in the center and be gradually discharged as the amount increases.
