A crushing method of a crushing device for solid waste treatment comprises the following operation steps:
Step 1: the waste is separated by the first separating roller 4 and the second separating roller 10, so that the waste with different sizes respectively passes through different charging barrels 5, and when the large waste passes through the charging barrels 5, the first processing component is used for primary crushing, and the waste and the small waste are conveyed into the processing chamber 102 by the feeding roller 3;
Step 2: the combustion chamber 101 heats the treatment chamber 102, the air inlet pipe 8 containing flue gas is connected with the bag-type dust collector body 7 through the heat exchanger 22 to remove dust, and discharged gas is conveyed into the air pipe 20 through the heat exchanger 22 to carry out secondary air flow crushing on the waste materials which are crushed primarily;
Step 3: the second fan 27 pumps the crushed waste particles into the third processing assembly for grinding, and pumps the crushed waste particles back into the bag-type dust collector body 7 for collection through the ash bucket.
Here, the entire operation is described again in general:
when the treatment chamber 102 reaches a preset temperature, the waste discharging end of the upper station of the treatment box 2 is positioned at one end of the first material distributing roller 4 and the second material distributing roller 10, smaller waste directly falls into the charging barrel 5 from the discharging cavity at the initial stage of conveying, larger waste falls into the charging barrel 5 from the discharging cavity at the widest of the first material distributing roller 4 and the second material distributing roller 10, the crushing roller 14 rotates at a high speed under the drive of the second gear 16 and the third gear 18 during working, the high-speed impact of the hammer head 1401 crushes the waste, the elastic plate 15 bumps the waste impacted by the hammer head 1401 again with the high-speed rotating hammer head, the crushing effect is carried out again to enable the size of the material conveyed into the reaction barrel 1 to be basically consistent, the waste is conveyed into the dust absorbing barrel 5 through the bag collector 7 at one side of the dust absorbing body 8 during working,
The air sucked by the first fan 23 is conveyed to the high-pressure nozzle 21 in the air pipe 20 through the air outlet pipe 24 which exchanges heat with the air inlet pipe 8 on the bag-type dust collector body 7, the supersonic air flow is blown into the collecting tray 19 to form a high-speed air flow vortex, the high-speed air flow vortex drives the waste which is primarily crushed to generate high-speed movement, in the movement process, the waste with lower speed and the waste with higher speed are subjected to strong collision and crushing, the generated centrifugal force moves the large-particle waste at the periphery of the collecting tray 19, the required collection of waste particles to the center is achieved,
Under the action of the second fan 27, the waste particles reaching the requirements are pumped between a pair of grinding rollers 28 for fine grinding, and ash generated by fine grinding is collected for uniform treatment under the action of the first fan 23 arranged on the bag-type dust collector body 7.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
