In addition, in one embodiment, the second spring 66 has a greater spring force than the first spring 42.
In an initial state, the separation motor 30 is located at the uppermost end under the elastic force of the supporting spring 31, the magnet 76 and the bearing plate 27 are in an adsorption state, the first rotating shaft 70 is connected with the second rotating shaft 29, the blocking rod 20 is located at the uppermost end, the water inlet 21 and the liquid inlet pipe 37 are blocked, the second shutter 39 is in an open state under the pulling of the second pull rope 62, the first shutter 32 is in a closed state under the elastic force of the first spring 42, the third rotating shaft 49 is connected with the fourth rotating shaft 50, the supporting circular plate 54 is located in the dewatering cavity 55, and the spout 38 is closed.
When recycling processing is needed, adding a plastic meal box into the hopper 69, wherein the plastic meal box is gathered on the upper side of the stirring blade 12, then starting the separation motor 30, wherein the motor 30 drives the second rotating shaft 29 to rotate, further drives the first rotating shaft 70 to rotate, further drives the stirring blade 12 to stir the plastic meal box, further causes meal box fragments to fall into the separation cavity 18, when the meal box fragments in the separation cavity 18 accumulate to a certain weight, the magnet 76 is separated from the bearing plate 27, the bearing plate 27 loses the suction force of the magnet 76 and moves downwards to the lowest end under the action of gravity, further the separation motor 30 moves downwards to the lowest end, and further the blocking rod 20 moves downwards and is communicated with the liquid inlet pipe 37 and the water inlet 21; at this time, the first rotating shaft 70 is disconnected from the second rotating shaft 29, so that the stirring blade 12 does not rotate, and the unbroken meal boxes are clamped on the upper side of the stirring blade 12; meanwhile, the separating motor 30 drives the connecting plate 33 to move downwards, and further drives the pull rod 60 to move downwards, and further the second pull rope 62 is loosened, and further the second spring 66 lifts up the push rod, and further the second shutter 39 rises and closes, and further the second shutter 39 pulls the first pull rope 41, and further the first shutter 32 moves downwards and opens, and meanwhile, the blocking rod 20 moves downwards and drives the connecting rod 24 to move downwards, and further drives the fourth rotating shaft 50 to move downwards and separate from the third rotating shaft 49 through the L-shaped rod 25 and the second bearing 47, and since the sleeve 52 is blocked by the block 57, the fourth rotating shaft 50 moves downwards and simultaneously drives the supporting circular plate 54 to move downwards and move out of the dewatering cavity 55, at this time, the object in the dewatering cavity 55 can be discharged, at this time, the dewatering motor 26 is not opened, and this part does not play a role; then the water level in the separation chamber 18 gradually rises and floats the fragments of the lunch box, the residual food residue which is not poured clean in the lunch box sinks at the bottom, the water level continuously rises until the food residue flows out of the outlet chamber 14 and carries the fragments of the lunch box out, the fragments of the lunch box are accumulated at the right side of the second baffle 39, at this time, the spray head 38 is opened and the fragments of the lunch box at the lower side are degreased, and the redundant waste water and the cleaning solution are discharged from the drain pipe 40 through the filtering inclined plate 36; when the infrared sensor 13 detects that no more fragments flow out, the infrared sensor 13 controls the switch valve 74 to be opened, because the diameter of the slag discharge pipe 16 is larger than that of the water inlet 21, the water level in the separation cavity 18 is quickly reduced, the weight on the bearing plate 27 is also quickly reduced, the separation motor 30 rises under the elastic force of the supporting spring 31 until the bearing plate 27 is adsorbed by the magnet 76, and at the moment, the infrared sensor 13 controls the switch valve 74 to be closed; at the moment, the separation motor 30 moves to the uppermost side again, the first rotating shaft 70 is connected with the second rotating shaft 29 again, fragments of the lunch box continue to accumulate in the separation cavity 18, and the water inlet 21 and the liquid inlet pipe 37 are blocked; meanwhile, the separation motor 30 moves upwards to drive the connecting plate 33 to move upwards, further drive the pull rod 60 to move upwards and pull the second pull rope 62 upwards, further drive the push rod 64 to move downwards and drive the second stop door 39 and the stop rod 63 to move downwards, further drive the first stop door 32 to move upwards and close under the elastic force of the first spring 42, and at the moment, fragments on the filtering inclined plate 36 slide into the dewatering cavity 55 through the discharge pipe 46;
meanwhile, the connecting plate 33 moves upwards to drive the fourth rotating shaft 50 to be connected with the third rotating shaft 49 again through the blocking rod 20, the connecting rod 24, the L-shaped rod 25 and the second bearing 47, and then the dewatering motor 26 is started to drive the third rotating shaft 49 and the fourth rotating shaft 50 to rotate, further drive the sleeve 52 and the supporting circular plate 54 to rotate and carry out rotary dewatering on the lunch box fragments;
when the weight of the pieces of lunch box in the separating chamber 18 is again accumulated and the separating motor 30 moves down again, the pieces of the lunch box dried are discharged from the lower side of the dehydrating chamber 55 and the first cycle is completed.
The invention has the beneficial effects that: a large amount of plastic meal box garbage generated due to the rise of the take-out industry in recent years is crushed, cleaned, separated, deoiled and dehydrated to be converted into polypropylene fragments which can be reused, namely, the plastic meal box type white garbage which is difficult to degrade is treated, meanwhile, the plastic meal box plays the residual value and becomes polypropylene raw materials with wide application, the operation of the whole recycling and processing process is very simple, the labor intensity is low, and the polypropylene meal box is worthy of popularization.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
