Principle of operation
Firstly, a heating device is placed below a heating barrel 10, then a feeding door 57 arranged on the surface of a feeding bin 25 is opened, the feeding door 57 is pulled out to drive a door connecting rod 59 to be pulled out, and the upper end and the lower end of a connecting shaft 61 are respectively connected with a filter plate pull column 63 and the door connecting rod 59 through rotating structures, so that the feeding door 57 can pull the upper filter plate pull column 63 to move outwards after being opened, and when the filter plate pull column 63 moves outwards, the other end of the filter plate pull column 63 is connected with a filter wall connecting piece 53 to drive a filter wall 26 to move to open a closed channel between the feeding bin 25 and the heating barrel 10 for a certain distance, so that soil needing to be repaired can be added into the heating barrel 10;
after soil is added, the feeding door 57 is closed, so that the filter wall 26 is reset to separate the feeding bin 25 from the heating barrel 10, and the accidental flying-out of soil in the operation process of the equipment is prevented;
after the rotating motor 12 is started, the driving gear 69 is driven to rotate through the output end, the driving gear 69 rotates to drive the driven gear 70 engaged with the driving gear to rotate, the driven gear 70 rotates to drive the heating barrel 10 fixedly connected with the driving gear to rotate, when the heating barrel 10 rotates, the driving internal gear 14 also rotates because the inner wall tongue of the heating barrel 10 is provided with the driving internal gear 14, the fixed column 15 sleeved in the driving internal gear 14 cannot rotate because the fixed column is fixedly arranged in the power source support column 13 below the motor sleeve 11, and simultaneously, the fixer 16 fixedly arranged outside the fixed column 15 in the heating barrel 10 cannot rotate, so that the stirring transmission rod sleeve 18 below the fixer 16 can position the stirring transmission rod 20 inside, the stirring transmission gear 19 at one end of the stirring transmission rod 20 can be engaged with the driving internal gear 14 above to drive the stirring transmission rod 20 to rotate, and the rotation of the stirring transmission rod 20 can drive the stirring driving bevel gear 21 at the other end to rotate, the rotation of the stirring driving bevel gear 21 drives the stirrer rotating wheel 22 which is meshed with the stirring driving bevel gear and is arranged on the lower end face of the fixed column 15 to rotate, and the stirrer rotating wheel 22 rotates to drive the stirrer rotating shaft 23 below to rotate, so that the cams 54 sleeved on the lower end face of the stirrer rotating shaft 23 can rotate and push the stirring plate connecting columns 56 on the two sides to move;
the cam 54 is in an eccentric design, so that the stirring plate connecting columns 56 on the two sides are intermittently pushed to move, but the two stirring plate connecting columns 56 are respectively pushed by the connecting column springs 55, so that the two stirring plate connecting columns can reset after being intermittently moved out, and the soil is stirred and is fully heated;
when the soil is heated to volatilize the organic substances and generate gas, the gas should be accumulated in the heating barrel 10, but since the feeding bin 25 rotates together with the heating barrel 10, when the feeding bin 25 rotates, the supporting rollers 32 which are in supporting contact with the feeding bin are driven to rotate, therefore, the rotation of the supporting rollers 32 drives the inner roller shafts 33 to rotate, so that the roller transmission gears 34 at the tail ends of the roller shafts 33 rotate, the roller transmission gears 34 rotate, so that the gear ring 28 which is meshed with the upper supporting rollers drives the air exhaust bin 27 to rotate, because the inner wall of the air extraction bin 27 is fixedly connected with the rotating shaft fixing column 40, the rotating shaft fixing column 40 drives the fan rotating shaft 41 in the middle to rotate along with the rotation of the air extraction bin 27, so that the fan blade 42 fixedly arranged outside the fan rotating shaft 41 rotates to extract the volatile gas in the heating barrel 10, and the volatile gas is filtered by the filter wall 26 to prevent the solid substances from being extracted together to enter the condenser 39, thereby achieving the protection purpose;
after the volatile gas enters the condenser 39, because the condenser 39 is designed to be inclined downwards, the volatile gas firstly contacts the upper inner wall of the condenser 39 and is condensed and dropped on the surface of the condensation and collection film 44 below under the action of condensate in the condensate channel 68, one part slides into the condensate collector 43 along the condensation and collection film 44 and the condenser 39 to be collected, and the other part is deposited on the surface of the condensation and collection film 44;
the roller transmission gear 34 rotates continuously to drive the driving eccentric wheel 36 connected with the roller transmission gear in a meshing way to rotate, the rotation of the driving eccentric wheel 36 enables the eccentric transmission rod 37 at the eccentric position to rotate around the driving eccentric wheel rotating shaft 35 to drive the eccentric telescopic rotating shaft 46 to rotate together, the eccentric driven wheel 47 is driven to rotate because the eccentric telescopic rotating shaft 46 can extend and contract, the force transmitted to the eccentric driven wheel 47 is approximately round, the eccentric driven wheel 47 rotates to throw the hammer connecting rod 48 and the collecting film hammer 49 at the other side, and the collecting film hammer 49 always strikes the condensing and collecting film 44 in one direction to strike the condensing and collecting materials on the surface of the condensing and collecting film into the condensate collector 43 because the hammer connecting rod 48 is provided with the hammer limit 66 behind to prevent the collecting film hammer 49 from reversing.
