[0058] Detailed instructions for use: When the solid waste crushing and recycling energy-saving utilization device is needed to crush solid waste, the following steps need to be performed:

[0059] S1, before installing the heat recovery waste drying mechanism onto the crushing roller and the feed hopper, first rotate the threaded rod to separate it from the screw hole on the auxiliary plate, then move the sealing plate to drive the auxiliary plate to separate from the inner wall of the arch plate, so as to complete the removal of the sealing plate, thereby completing the opening of the auxiliary hole;

[0060] S2, when the auxiliary hole is opened, the connecting plate is moved to drive the heat conducting plate and the elastic heat conducting ring to pass through the auxiliary hole and the feed hopper in turn to reach the inside of the crushing frame, and then the connecting plate is moved to drive several elastic heat conducting rings to be respectively inserted into the inside of several annular holes on the crushing roller, and then the connecting plate is rotated to drive the mounting hole, and the mounting rod on the inner wall of the crushing frame is inserted into the mounting hole, and then the adjusting ring is sleeved on the arc surface of the mounting rod, and finally the adjusting ring is rotated to move along the arc surface of the mounting rod. When the adjusting ring drives the rubber pad to abut against the connecting plate, the positioning of the connecting plate is completed, and the above steps are repeated to make the two sets of connecting plates and elastic heat conducting rings fixed firmly in the crushing frame;

[0061] S3, first move the two drying plates and put them into the two rectangular holes on the inner wall of the feed hopper respectively. When the drying plates are fitted with the inner walls of the rectangular holes, rotate the baffle along the inner wall of the fixing seat so that one side of the baffle presses against the drying plates, and then rotate the nut along the arc surface of the screw so that one side of the nut presses against the fixing seat, thereby limiting the baffle so that the baffle can limit the drying plates to prevent the drying plates from falling off from the rectangular holes during use. When the drying plates are firmly fixed, move the fixing block and insert it into the fixing hole. When the fixing block is inserted into the fixing hole, adjust the insertion rod and insert it into the insertion hole. The spring will push the slider to move along the inner wall of the sliding hole, and the slider drives the insertion rod. When the insertion rod is inserted into the insertion hole on the arc surface of the fixing block, the limiting of the fixing block can be completed, thereby achieving the effect of making the connection between the fixing block and the fixing hole more firmly.

[0062] S4, after completing the above steps S2-S3, the installation of the heat recovery waste drying mechanism can be completed, and then the positioning rod fixed on the crushing frame is inserted into the positioning hole on the lower surface of the sealing plate. When the positioning rod is inserted into the positioning hole, the auxiliary plate will fit with the inner wall of the arch plate, and the screw hole on the auxiliary plate will be aligned with the threaded rod. Then, the threaded rod is rotated to connect with the screw hole, and the sealing of one side of the feed hopper can be completed;

[0063] S5, when the above steps are completed, first put the solid waste into the feed hopper, the solid waste will fall into the crushing frame through the feed hopper, and then start the driving motor to drive one of the gears to rotate, and the other gear of the gear rotates synchronously with it, the gear drives the shaft to rotate, and the shaft drives the two crushing rollers inside the crushing frame to rotate, so that the crushing rollers crush the solid waste. In the process of crushing the solid waste by the crushing rollers, the temperature of the crushing rollers will increase due to the friction and impact of the solid waste. The heat of the crushing rollers is transmitted to the drying plate along the elastic heat-conducting ring, the heat-conducting plate, the heat-conducting wire, and the fixed block in turn, and then the drying plate can be used to dry the wet solid waste;

[0064] S6, before using the drying plate to dry the wet solid waste, first start the servo motor to drive the driving wheel to rotate, the driving wheel drives the driven wheel to rotate with the help of the belt, the driven wheel drives the screw to rotate, the screw drives the connecting plate, so that the connecting plate moves along its arc surface in the direction close to the feed hopper, the connecting plate drives the two partitions to move through the side of the feed hopper, so that the partition abuts against one side of the sealing plate, when the partition abuts against the sealing plate, the personnel can put the wet solid waste into the space formed by the feed hopper and the partition for drying;

[0065] S7, when the wet solid waste is dried, the servo motor is started to drive the screw to rotate in the opposite direction, the screw drives the connecting plate to move away from the feed hopper, and the connecting plate drives the two partitions to move away from the sealing plate, and then the solid waste falls into the crushing frame along the inclined surface of the drying plate. When the solid waste falls into the crushing frame along the inclined surface of the drying plate, the step S5 is repeated to continue crushing the waste and transmitting the heat on the crushing roller;

[0066] S8, repeating steps S5-S7, thereby repeatedly crushing and drying the solid waste.
