The leachate treatment is the last step of the sanitary landfill, if the treatment is not thorough, immeasurable pollution and harm can be brought to the surrounding environment, and meanwhile, the threat to the human health is brought. The existing landfill leachate needs to be collected and concentrated at high power before being treated in a centralized way. At present, high-temperature evaporation is usually adopted to carry out high-power concentration on percolate, but the method has the defects of high energy consumption and low efficiency; therefore, the waste combustion is tried to be used for assisting in heat supply to reduce energy consumption at present, but the waste is complex in components, difficult to combust, insufficient in combustion and unstable in heat supply. As shown in figures 1 and 2, in the invention, untreated garbage is put into the drying bin 21 from the feeding port 24, the garbage is dried in the drying bin 21, and percolate is rapidly seeped into the percolate storage 31 in the filtering mechanism 3. The dried garbage enters the combustion bin 41 of the combustion mechanism 4 for combustion, the waste heat of the combustion in turn dries the garbage in the drying bin 21, and the heat supply for the percolate in the percolate bin 31 assists evaporation and concentration. The garbage drying device can utilize the waste heat of garbage combustion to dry garbage, not only can assist garbage leachate to be filtered out from the garbage, is convenient for collecting the leachate, improves the collection efficiency, but also can utilize the filtered grease to be sprayed on the garbage, so that the garbage can be fully combusted during subsequent combustion, and heat can be continuously supplied; in addition, the invention utilizes the waste heat of garbage combustion to evaporate and concentrate the percolate, thereby saving energy consumption.

As a further scheme of the present invention, the drying mechanism 2 includes a drying chamber 21, a first rotating shaft 22 rotatably mounted in the drying chamber 21 and externally connected to a driving source, a twisted cage blade 23 fixedly mounted on the first rotating shaft 22, a feeding port 24 formed at one end of the drying chamber 21, and the other end communicated with the combustion mechanism 4, and the lower portion of the drying chamber 21 is connected to the filtering mechanism 3. As shown in figure 4, when the garbage treatment device works, the garbage is conveyed by the twisting cage blades 23, and the garbage is dried, stirred and extruded while being conveyed, so that the garbage is crushed into small blocks to be convenient to burn, and the garbage is extruded to extrude leachate, and the solid-liquid separation efficiency is improved.

As a further scheme of the present invention, the filtering mechanism 3 comprises a percolate storage 31, and the interior of the percolate storage 31 is communicated with the working box 1; a second rotating shaft 32 externally connected with a driving source is rotatably arranged in the percolate storage 31, and a return heating pipe 33 is arranged on the second rotating shaft 32; the below that 31 tops in leachate storehouse are passed through oily water filter tube 34 and are dried storehouse 21 links to each other, the filter screen 35 of filtering the solid is installed to oily water filter tube 34 upper end, and the filtration membrane 36 of filtering the grease is installed to the lower extreme, and the middle part is equipped with the opening and connects grease collection storehouse 37, grease collection storehouse 37 is close to one side of combustion mechanism 4 and installs and be used for spraying the grease to the piston mechanism 5 in the combustion mechanism 4. As shown in fig. 4, since the domestic garbage contains a large amount of grease, when the present invention is in operation, the garbage leachate dried and extruded from the upper drying bin 21 firstly enters the oil-water filtering pipe 34 to filter out the grease, and then falls into the leachate bin 31 below to be heated at high temperature, so as to complete high-power concentration. The invention adopts the mode of stirring and heating by the square-shaped heating pipe 33 to heat and evaporate the percolate in the percolate storage 31, and the design of the square-shaped heating pipe 33 increases the heating area and improves the heating efficiency. The middle part of the oil-water filter pipe 34 is provided with an opening which is connected with a grease collecting bin 37, and filtered grease is collected into the grease collecting bin 37, so that the grease can be sprayed into a combustion bin 41 for ignition through a piston mechanism 5. In the practical work of the invention, in order to prevent a large amount of water evaporated from the percolate storage 31 from reentering the drying storage 21 through the oil-water filter pipe 34 to wet the dried garbage, the invention adopts an oil seal mode to seal the oil-water filter pipe 34. As shown in fig. 5, because the connection port of the grease collection bin 37 is disposed in the middle of the oil-water filter pipe 34, when the working is performed, a part of grease can still be accumulated at the bottom of the oil-water filter pipe 34, and because the boiling point of grease is much higher than that of water, when the liquid in the percolate storage 31 is evaporated, the grease at the bottom of the oil-water filter pipe 34 is still liquid, an oil seal can be formed, so that the transpired water vapor below is prevented from entering the drying bin 21 through the oil-water filter pipe 34, and the water vapor can only escape into the working tank 1 and finally be discharged through the air outlet 14. The oil-water filtering pipe 34 in the invention can not only filter and collect the grease in the percolate so that the grease can be sprayed into the combustion bin 41 for ignition through the piston mechanism 5 in the following process, thus the garbage in the combustion bin 41 can be fully combusted, and the heat can be stably supplied, but also an oil seal can be formed by utilizing the gravity of the grease accumulated on the next work part of the oil-water filtering pipe 34, so that a large amount of moisture evaporated by the percolate bin 31 is prevented from entering the drying bin 21 again through the oil-water filtering pipe 34 to wet the dried garbage, the subsequent garbage combustion is hindered, the structure is simple, and the energy consumption is saved.

As a further scheme of the invention, the combustion mechanism 4 comprises a combustion chamber 41 and a preheating chamber 42 for preheating the grease, a bearing plate 43 for bearing the dried garbage is vertically and slidably mounted in the combustion chamber 41, the bottom end of the bearing plate 43 is connected with the bottom surface of the combustion chamber 41 through a first compression spring 44, and a communicating port 45 is formed on one side chamber wall of the combustion chamber 41 close to the drying concentration area 11 and communicated with the drying concentration area 11.

As shown in fig. 2, 4 and 6, the garbage dried by the present invention falls on the carrying plate 43 in the combustion chamber 41 for combustion, the provided heat enters the drying concentration region 11 through the communicating port 45, the garbage in the drying mechanism 2 is dried, and the percolate in the filtering mechanism 3 is evaporated and concentrated, so that energy consumption is saved.

As a further scheme of the invention, the piston mechanism 5 comprises a compression plate 51 which is slidably mounted in the grease collection bin 37, the compression plate 51 is hinged with a rotating disc 53 which is arranged in the preheating bin 42 through a connecting rod 52, the rotating disc 53 is rotatably mounted in the preheating bin 42, a preheating box 54 is arranged in the preheating bin 42, the preheating box 54 is communicated with the grease collection bin 37 and the combustion bin 41, and a spray nozzle 55 is mounted at the communication position of the preheating bin 42 and the combustion bin 41.

Most of the grease collected in the household garbage is vegetable oil, which has the advantages of large heat value and long burning time, but the burning point is higher. In order to be ignited as an ignition product to promote the garbage to be fully combusted, the garbage needs to be preheated before being sprayed. As shown in fig. 8 and 9, the rotating disc 53 of the present invention rotates, the rotating disc 53 drives the compression plate 51 to reciprocate in the grease collection bin 37 through the connecting rod 52, the compression plate 51 firstly extrudes the grease into the preheating tank 54, and the preheating tank 54 is located near the combustion bin 41, so that the temperature is high, and the grease in the preheating tank 54 can be automatically heated when the garbage is combusted. When the compression plate 51 presses the next grease into the preheating tank 54, the grease which has been preheated in the preheating tank 54 is pressed through the spray nozzles 55, and is sprayed onto the garbage in the combustion chamber 41 in an atomized manner to serve as a combustion initiator for sufficient combustion. The invention collects the grease in the garbage percolate and sprays the ignition substances into the combustion bin 41, thereby promoting the garbage to be fully combusted and stably supplying heat.

As a further aspect of the present invention, a sliding groove 531 is formed on the disc surface of the rotating disc 53, a guide post 532 is fixedly installed in the sliding groove 531 along the radial direction of the rotating disc 53, a sliding block 533 is slidably installed on the guide post 532, and the sliding block 533 is hinged to the connecting rod 52; the sliding groove 531 is provided with an air pressure type telescopic rod 534, one end of the air pressure type telescopic rod 534 is connected with the bottom of the sliding block 533, and the other end is connected with an air bag 535 fixedly installed on the inner wall of the preheating bin 42; the bearing plate 43 is fixedly provided with a squeezing block 536, the squeezing block 536 is slidably arranged on the bin wall of the preheating bin 42, and the squeezing block 536 is arranged above the air bag 535.

In practical operation, the burning rate of the garbage in the burning bin 41 of the present invention varies, and the weight of the garbage stacked on the carrying plate 43 varies. When the garbage is difficult to burn, the weight of the garbage stacked on the bearing plate 43 is larger, and more ignition agent needs to be sprayed to assist burning, so that the garbage is fully burnt; when the garbage is easy to burn, the weight of the garbage stacked on the bearing plate 43 is smaller, and only a small amount of ignition agent needs to be sprayed at the moment. As shown in fig. 9 and 10, the present invention can automatically adjust the amount of the sprayed grease according to the weight of the garbage stacked on the carrying plate 43. When the weight of the garbage accumulated on the bearing plate 43 is large, the bearing plate 43 moves downwards, the pressing block 536 fixed on the bearing plate 43 presses the air bag 535, the air in the air bag 535 drives the air pressure type telescopic rod 534 to extend and jack up the sliding block 533 sliding on the guide post 532, because the connecting rod 52 enables the sliding block 533 to be hinged on the sliding block 533, when the sliding block 533 moves upwards, the crank in the piston mechanism 5 of the invention is lengthened, the stroke of the reciprocating motion of the piston mechanism 5 is lengthened, so that the amount of grease compressed by the compression plate 51 is also increased, and the grease sprayed into the combustion chamber 41 in the preheating tank 54 is also increased; similarly, when the weight of the garbage stacked on the bearing plate 43 is small, the bearing plate 43 moves up under the restoring force of the first compression spring 44, the pressing block 536 fixed on the bearing plate 43 does not press the air bag 535, the air bag 535 recovers, the sliding block 533 moves down, the crank in the piston mechanism 5 is shortened, and the grease sprayed into the combustion chamber 41 in the preheating tank 54 due to the shortened stroke of the reciprocating motion of the piston mechanism 5 is also reduced. The invention can automatically adjust the spraying amount of the grease according to the weight of the garbage stacked on the bearing plate 43, and when the weight of the garbage stacked on the bearing plate 43 is larger, the atomizing nozzles 55 spray more grease, so that the garbage is fully combusted; when the weight of the garbage accumulated on the bearing plate 43 is smaller, the atomizing nozzles 55 spray less grease, so that the garbage is combusted to supply heat, the combustion is sufficient, the heat is stably supplied, and the energy consumption is saved.

As a further scheme of the invention, the working box 1 is provided with an air inlet 13 on the top surface of the combustion heat supply area 12, and an air outlet 14 on the top surface of the drying and concentrating area 11. The invention arranges the air inlet 13 to ensure that the garbage in the combustion bin 41 can be fully combusted.
