[0040] The inclined surface 215a of the guide plate 215 is inclined in the transfer section, the first guide rail 217 is fixed to the body 210 through the bracket 217a, and the second guide rail plate 218 is located at the lower side of the body 210 and at the lower side of the return direction of the transfer section.

[0041] The first guide rail 217 is at the lower end of the transfer part in the departure direction, and the second guide rail 218 is at the lower end of the transfer part in the return direction, which ensures the stable transfer of the transfer part as a whole; the first guide rail 217 is used to set the deflector 223 of the moving part, which together with the first guide rail 217 has the function of guiding the transfer part, and the second guide rail 218 is located on the lower side of the transfer part in the return direction to support the return of the transfer part to prevent the transfer chain from being attracted by the sagging inside the fuselage and causing friction damage; the inside of the fuselage needs to keep a certain distance from the ground, and the fuselage can use the transfer plate that can start and return to collect the incineration materials.

[0042] The transfer part 220 includes a plurality of transfer chains 221 repeatedly connected to each other, the transfer chain 221 is provided with a bracket 222 and a deflector 223, the bracket 222 is provided with a horizontal transfer plate 224b and a vertical transfer plate 224b. The transfer plate 224 is shaped such that a storage space for the incinerated materials is formed between the horizontal transfer plate 224a and the vertical transfer plate 224b.

[0043] In some implementations, in order to reduce the gap between adjacent horizontal transfer plates 224a, the length of the horizontal transfer plates 224a may be increased.

[0044] The transfer chain 221 controls the rotation of the deflector 223 through the pins 221 a , and the rotatable action sprocket 225 connected to the driving unit 230 is disposed on both sides of the body 210 .

[0045] The driving unit 230 includes an engine 231, a driving chain 232 to which the driving force is transmitted by the engine 231, a driving sprocket 233 connected to the shaft of the engine 231 and capable of starting the driving chain, a longitudinal gear 234 connected to the driving chain and bundled with the driving shaft 234a, and a supporting section 235; wherein the longitudinal gear 234 can rotate according to the driving chain and start the driving shaft to rotate; the supporting section 235 is connected to the bearing on the driving shaft 234a, and can be used to adjust the interval of the driving shaft 234a, and adjust the transfer chain and the driving chain.

[0046] The supporting section 235 includes a bearing chamber 235b and a guide platform 235a for moving in a certain direction.

[0047] The injection part 240 is supplied with air through an air supply system 241 , and the injection port 243 is provided with air nozzles 242 distributed at equal intervals to provide air, which are arranged at the upper side and the lower side of the discharge port 212 respectively.

[0048] The working principle of the transfer device 20 described in the present invention is as follows: the transfer device 20 is a device that receives the crushed incineration material from the crushing device 10 and transfers it to the incineration device. The crushed incineration material can be moved from the input port to the discharge port by the transfer plate 224 fixed to the transfer chain 221, relying on the rotational force of the driving part. In this process, in order to facilitate the input of the incineration material into the incineration device, an injection part that injects air in the same direction as the incineration device is provided at the discharge port to facilitate the input of the incineration material. The incineration device can prevent the incineration material put into the incineration furnace from being discharged again by the injected air, and can form an "air curtain" to prevent the high-temperature hot air of the incineration device from moving to the side of the transfer device.

[0049] In addition, the stacking space in the transfer plate of the transfer part can store and transfer a certain amount of incineration materials, and can supply uniform incineration materials; and through the first guide rail and the second guide rail, the transfer chain can be prevented from sagging and guidance can be provided, thereby minimizing friction damage caused by detachment and dragging of the incineration materials.

[0050] In some embodiments, the transfer plate is preferably made of polyurethane material to facilitate replacement and prevent noise caused by friction.

[0051] The incineration device 30 is composed of a base plate 310 , an incineration body 320 , a combustion system 330 , an air supply system 340 , an inspection door 350 , and an exhaust system 360 .

[0052] The substrate 310 is composed of a plurality of The three parts are connected in a Chinese character, which can stably support the structure of the ground incinerator.

[0053] The interior of the incineration machine body 320 has a combustion space 321 of a certain size, and an incineration material port 325 for feeding incineration materials is arranged at the upper part of the combustion space 321. The combustion space is provided with an inner wall 322 and an outer wall 324. The inner wall 322 is made of refractory material and is provided with fixed blocks 323 at equal intervals to firmly fix the refractory material.

[0054] In some embodiments, the inner wall 322 is prepared by mixing aluminum alloy, water, aluminum powder, aluminum alloy, and original infrared powder.

[0055] In some embodiments, the original infrared powder is selected from any one or more combinations of thorium maline, loess, sericite, amethyst, raw ore, bamboo charcoal, Yiwang stone, Guiyang stone, obsidian, Maipan stone, Guangming stone, lava, and guixian stone.

[0056] In some embodiments, the inner wall 322 is made of a ceramic ingredient to form a fire-resistant wall to prevent deformation or damage caused by high-temperature incineration heat.

[0057] The combustion system 330 is a combustion box 331 that supplies fuel to multiple nozzles arranged on the lower outer side of the incineration body 320 to burn the input combustion materials.

[0058] When the combustion system 330 is in operation, the heat of the heating igniter is used to ignite the fuel injected from the lower side of the incinerator, so that the combustible material can be burned.

[0059] In actual use, either one nozzle or multiple nozzles can be used simultaneously. When the flame temperature sensed by the temperature sensor is lower than the necessary temperature, multiple nozzles can be used to spray fuel.

[0060] The air supply system 340 supplies air to the interior of the incineration body 320 through the blower 341, so that the incineration material can be fully burned through the supply of fuel and air.

[0061] In the air supply system, air nozzles are distributed at equal or unequal distances in the vertical direction of the center of the lower side of the incinerator body and in the upper direction. The spray direction of the air nozzle is opposite to that of the adjacent air nozzle, and an air curtain is formed on the upper part. Due to the different spray directions, vortexes are generated inside, thereby improving combustion efficiency.

[0062] The inspection door 350 is formed by opening one side of the incinerator body 320, and can be used to confirm the incineration status and the discharge of ash after the incineration material is burned.

[0063] In some embodiments, the inspection door 350 includes a handle 353, a locking ring 355, and a padlock 354; wherein the inspection door 350 is fixed to the incinerator via a hinge shaft 351 and can rotate around it, thereby locking or unlocking the locking ring 355 or the padlock 354 as the handle 353 rotates.

[0064] The exhaust system 360 is located at the upper part of the incinerator body 320, and exhausts the smoke of the incineration material burned in the combustion space; that is, the exhaust system 360 exhausts the combustion smoke, including the structure of minimizing the discharge of fine dust to the outside.

[0065] The fuel supply device 40 includes a combustion chamber 410, an auxiliary tank 420 for evenly supplying fuel, and an auxiliary combustion chamber 430 and a temperature sensor 440 used according to the degree of burning of the burning fuselage.

[0066] The combustion chamber 410 is supplied with fuel through the combustion system 330, and the combustion system 330 controls the supply of fuel through the valve 333 and the pump 332 for supplying fuel. During operation, according to the signal of the control unit, during the opening and closing of the valve 333, the pump 332 is started to replenish the fuel to the auxiliary tank 420. A water level sensor for fuel measurement is provided in the auxiliary tank 420. According to the signal of the water level sensor, the control unit will generate the signal of opening and closing the valve 333 and the pump switch.

[0067] During the operation of the auxiliary combustion chamber 430, the fuel is controlled by the valve 434 and the pump 433 on the auxiliary combustion system 431, and the action is performed according to the sensing signal of the installed water level sensor or can be manually started according to the user's needs.

[0068] In some embodiments, the auxiliary combustion chamber 430 can be structurally adjusted according to the amount of incineration material input, such as providing a sensor that can measure the transfer amount of the incineration material. When the transfer amount is too much, the sensor can generate a control signal to start the auxiliary combustion chamber; when the transfer amount is less, a control signal can be generated to only start the combustion chamber for operation.

[0069] In some embodiments, a plurality of auxiliary combustion systems are arranged at equal intervals on the incinerator body 320, located above the combustion chamber.

[0070] In actual operation, combustion is generally performed only through the combustion chamber 410. However, when there are a lot of incineration materials in the incineration device or the combustion is not smooth, fuel can be injected into the auxiliary combustion chamber to achieve uniform combustion of the entire incineration body. The method can be achieved through the signal of the control unit or by manual operation of the user.

[0071] The auxiliary tank 420 is connected to the combustion system 330 at the top and bottom respectively with transparent connecting pipes, and a flow meter 425 is provided for the user to confirm the extent of the fuel filling in the auxiliary tank. The combustion chamber 410 is at the bottom, and the top of the combustion chamber 410 is connected to the supply system 421 and valve 422 for supplying fuel, and also has a return pipe 423, which can return to the fuel tank 331 when the fuel is overfilled into the auxiliary tank.

[0072] In some embodiments, the combustion chamber 410 is connected to the incinerator body 320 through the socket 411 and is connected to the supply system 421. The hot igniter 414 heats and ignites the fuel sprayed from the nozzle 412 to the combustion space 413.

[0073] The auxiliary combustion chamber 430 is located at the upper side of the combustion chamber 410. Compared with the combustion chamber, the combustion efficiency can be improved by the auxiliary combustion chamber located at the upper part.

[0074] The temperature sensor 440 measures the temperature inside the incinerator body, so that the user can confirm the temperature inside the incinerator or start the auxiliary combustion chamber based on the measured temperature when the temperature is below the necessary temperature, thereby achieving additional combustion.

[0075] The air supply device 50 includes an air injection unit.

[0076] The air supply device 50 is connected to the air supply system 340 , and the air supplied by the blower 341 will reach the air injection part 510 inside the incinerator body. The air injection part 510 includes a cover 520 at the upper end and an injection nozzle 511 .

[0077] The injection nozzles 511 are holes 511 a opened along the outer direction of the air injection portion 510 , and the injection nozzles 511 are arranged at equal or unequal distances in the longitudinal direction of the air nozzle portion 510 .

[0078] In actual work, the spacing between the injection nozzles may vary due to the different total lengths, and the spacing between the injection nozzles from bottom to top may be arranged to be gradually narrower. The size of the hole 511a of the injection nozzle may be different as it goes up, and the size of the hole of the injection nozzle may gradually increase as it goes up. While the diameters of the injection nozzles arranged at the upper end (part B) and the lower end (part B) of the air injection part and the injection nozzles (part A) arranged between the above-mentioned injection nozzles (part B) are different, the angle formed by part B and the angle of the holes formed by part A, as well as the number of holes may also be different. (For example Fig.18 As shown: when the opening angle formed by part A is 10, the opening angle formed by part B is 20, and the number of holes in part A and part B will be different)

[0079] In some embodiments, when installing the incinerator, the amount of air injected at the lower end is different from the amount of air injected upward. Inside the incinerator, the amount of air injected can form an air curtain effect, and the air inside forms a vortex for a long time, which can make the incineration material burn. When the internal size of the incinerator is different, the corresponding various injection nozzle structures can also be installed. In this way, the air curtain formed inside the incinerator body can make the incineration material burn fully, and the air stagnation can be maintained for a long time to achieve complete combustion.

[0080] The opening angle is the opening angle (θ°) of the hole formed by the jet nozzle with the central axis of the air injection part, that is, when the opening angle of the jet nozzle located at the lower end of the air injection part is clockwise, the adjacent jet nozzle opens in the counterclockwise direction. Once again, the jet nozzle that opens in the counterclockwise direction, and its adjacent jet nozzle adopts the method of opening angle in the clockwise direction. The jet nozzles located at a certain interval have different injection angles. The injection directions of the air are interlaced clockwise or counterclockwise inside the incinerator to form a vortex. If the time is long, the incineration time of the incineration material is extended accordingly, and the incineration material can be completely burned.

[0081] In some embodiments, the injection direction of the fuel injection nozzle is arranged between the injection nozzles 511, so that the fuel and air can be mixed, thereby further promoting the combustion of the incineration material.

[0082] The stirring device 60 is partially located inside the incinerator body and partially located outside the incinerator body, and improves the combustion efficiency by stirring the incineration material put into the incinerator body. The stirring device 60 is composed of a support frame 610 located above the base plate 310, a driving means 620, a guiding means 630, an operating rod 640 and a sensor 650.

[0083] The supporting frame 610 is formed by connecting a plurality of frames to each other.

[0084] The driving means 620 includes an engine 621 and its driving shaft 622, a driving sprocket 623, a longitudinal sprocket 625, and a chain 624 for transmitting rotational force, and can rotate both forward and reverse.

[0085] The guiding means 630 includes a support platform 631 connected to the chain 624, a guide block 632 fixed to the support platform 631, a guide rod 633 having a guiding function in the length direction of the guide block 632, and a fixing platform 634 for fixing the guide rod 633 to the supporting frame.

[0086] The above-mentioned operating rod 640 has a certain length, and an air injection system 641 for supplying air is provided at the bottom. Air is supplied through an internal air passage 642. The supplied air is sprayed into the interior of the incinerator body through a nozzle hole 643. A plate-shaped stirring table 644 is provided at the bottom, and the incineration material is stirred using the operating rod.

[0087] The working principle of the stirring device of the present invention is as follows: the stirring device 60, under the action of the engine, makes the guide means connected to the chain 624 move forward or backward, and the operating rod moves in the incinerator body to stir, and the forward and backward movement is sensed between the guide blocks through the sensors 650 respectively arranged on both sides of the direction of the guide means. In this way, the incineration material in the incinerator body can be stirred, and during the stirring process, air is supplied to the operating rod from the incineration material, thereby further promoting the incineration.

[0088] In addition, in the present invention, two operating rods are connected to one driving means, and the two operating rods can be staggered with each other to connect two driving means respectively.

[0089] A stirring platform is installed at the lower end of the operating rod, but in order to improve the stirring efficiency, a pin-shaped stirring platform can also be installed around the operating rod.

[0090] The exhaust device 70 is composed of an exhaust hood 710 connected to the upper part of the incinerator body, a spray nozzle 720 and a water reservoir 730.

[0091] The exhaust hood 710 is composed of a flange 711 connected to the upper part of the incineration machine body and an exhaust passage 712 for exhausting the incineration smoke.

[0092] The spray nozzle 720 utilizes externally supplied water for spraying. In order to prevent the fine dust contained in the exhaust smoke from being discharged to the outside, the spray nozzle is located at the upper part or side of the moving passage; a plurality of spray nozzles may also be provided to spray in all directions.

[0093] The water storage platform 730 is located inside the moving passage 712, and is used to recover the water sprayed from the spray nozzle and discharge it to the outside through the drainage system 731, so that the fine dust in the treated water can be recovered.

[0094] Various configurations of the exhaust device can effectively collect the exhausted combustion fumes, thereby removing most of the combustion fumes exhausted to the outside.

[0095] The control device 80 is for controlling the operation of each element (10, 20, 30, 40, 50, 60, 70), and is composed of a closed circuit for control.

[0096] The working principle of the present invention is:

[0097] First, when the operating power is turned on by the control unit, each component (10, 20, 30, 40, 50, 60, 70) starts to operate.

[0098] At the start of operation, when the driving motor 131 starts working, the connected driving shaft 133 rotates and the driving shaft engaged with the driven gear 135 rotates in directions facing each other, at this time, the cutter is arranged along the axial direction of the driving shaft so that the blade is in a screw form.

[0099] At the same time, when the incineration materials are injected through the hopper 122, the rotating shredder breaks the incineration materials into a certain size and then drops to the bottom. The fallen incineration materials fall through the input hopper 211 of the transfer device 20, fall into the transfer part 220 in the main body 210, and start to move after a certain amount is accumulated on the transfer plate 224 in the transfer part 220.

[0100] When the incineration materials accumulated on the transfer plate are transferred to the discharge hopper 212, they freely fall into the incinerator on the discharge hopper side according to the return stroke of the transfer unit.

[0101] At this time, the injector 240 located on the side of the discharge hopper 212 injects air from the discharge hopper side into the incinerator, so that the falling incineration materials can be naturally introduced into the incinerator, thereby preventing them from being lost to the outside of the incinerator during the input process, and can also be used as an air curtain to prevent the flame of the incinerator from flowing back through the discharge hopper.

[0102] The incineration material put into the combustion space 321 inside the incineration device 30 is heated and burned by the fuel supplied by the combustion system 330 , and is completely burned by the combustion air supplied by the blower 341 .

[0103] In addition, during the combustion process, auxiliary fuel is supplied as needed through the auxiliary combustion chamber 430, which is located above the combustion chamber 410 to facilitate combustion in the combustion chamber. The operation of the auxiliary combustion chamber is carried out by a temperature sensor installed on the incinerator body.

[0104] In addition, the air to be supplied is sprayed at a certain interval in the height direction through multiple spray nozzles 511 in the air spray part, and the spray direction is alternately sprayed in the clockwise direction or the counterclockwise direction; the interval between the nozzles gradually narrows toward the height direction, and the diameter of the nozzle gradually increases toward the height direction.

[0105] The amount of air injected from the upper nozzle is increased compared to the amount of air injected from the lower nozzle to prevent the flame of the combustion process from rising to the upper side and being discharged to the outside, and to form an air curtain on the upper side to burn the incompletely burned incineration materials, which are incinerated again to ensure complete combustion.

[0106] The configuration, installation and structural form of the spray nozzle can be referred to Fig.17 and Fig.18 .

[0107] During the incineration process in the incinerator, the incineration material is stirred by the stirring device 60 to further improve the incineration efficiency. To this end, the stirring device operates the operating rod 640 through the driving device 620, and at the same time, the air is directly sprayed onto the incineration material through the operating rod 640, and the operating rod is controlled by the sensor to repeatedly move forward and backward, so that the stirring efficiency can be improved and the incineration material can be completely burned.

[0108] Fine dust that may be generated during the incineration process may be treated by water sprayed from a nozzle mounted on the upper side of the exhaust device 70, and the sprayed water may also be treated to facilitate the collection and treatment of the fine dust.

[0109] Therefore, when the present invention is used, the incineration material can be completely burned, and the entire structure can be installed in a small incineration site, which can greatly reduce the cost of installing the incinerator and the odor and fine dust generated during the incineration process and can be installed into an environmentally friendly incineration site.
