Technical Field
[0001] The invention belongs to the technical field of heat recovery devices for waste incineration, and in particular relates to a garbage storage device for a garbage power plant. Background Art
[0002] Waste-to-energy plants are facilities that generate electricity by incinerating domestic waste. This method of power generation can effectively reduce the volume of waste and achieve harmless and resourceful treatment of waste. In waste-to-energy plants, the heat energy generated by the incineration of waste is converted into electrical energy, which not only reduces the total amount of waste, but also achieves the reuse of energy.
[0003] The existing Chinese invention patent with classification number CN114216125B provides a coal chemical solid slag recycling system. The raw materials left on the bottom wall of the crushing furnace are pushed by the scraper. Under the action of centrifugal force, the raw materials will be rolled against the inner wall of the crushing furnace. The crushed raw materials are then incinerated to improve the utilization rate.
[0004] The incineration waste used in the waste-to-energy plant is partly mixed waste with biomass waste. It is inevitable that it will deteriorate and produce odor during storage. When incinerated, it is transported to the incinerator using a cart or a hanging basket. The slag produced will be removed from the incinerator. During the process, the waste is exposed to the air. The high-temperature slag will cause the temperature in the plant to be high. The combination of the two will lead to poor air quality in the storage and incineration space. In view of this, a waste storage device for a waste-to-energy plant is provided. Summary of the invention
[0005] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a garbage storage device for a garbage power plant.
[0006] The technical solution adopted to solve the above technical problems is:
[0007] A garbage storage device for a garbage power plant comprises a storage box, wherein the storage box is connected to an incinerator via a first conveyor and a second conveyor;
[0008] The storage box comprises an outer box and an inner box, the inner diameter of the top opening end of the inner box is increased to fix and block the top opening of the outer box, an interlayer is formed between the outer wall of the inner box and the inner wall of the outer box, an ashtray is provided at the bottom of the outer box, the inner box is located above the ashtray, a drainage hole connected to the interlayer is provided on the bottom surface of the inner box, and a drainage cavity is provided at the bottom edge of the outer box;
[0009] The incinerator comprises a furnace wall, the furnace wall is enclosed to form a combustion chamber and a slag chamber arranged up and down, the combustion chamber and the slag chamber openings are respectively provided with sealing doors, and the bottom surface of the slag chamber is provided as an inclined bottom surface whose height is inclined downward toward the opening;
[0010] Through the above technical scheme, when in use, excess moisture of the garbage to be incinerated in the inner box enters the drainage cavity through the drainage hole, slowing down the decomposition and odorization of the garbage to be incinerated, and the inner box transports the garbage to be incinerated to the combustion cavity through the conveyor 1, and the garbage to be incinerated is ignited and incinerated in the combustion cavity, and the generated slag falls downward into the slag cavity, slides down to the position of the conveyor 2 under the guidance of the inclined bottom surface, and the slag cavity pushes the accumulated slag into the ash tube through the conveyor 2, and the heat of the slag is transferred through the ash tube to heat the inner box and the interlayer, and the ash tube heats and vaporizes the waste water dripping into the drainage cavity, and the water vapor contacts the outer wall of the inner box to condense and release heat, thereby heating and drying the garbage to be incinerated in the inner box, so that the garbage to be incinerated is heated and sterilized to further reduce the decomposition phenomenon, and can be preheated before incineration, and the heat of the slag can be recycled to reduce energy consumption during garbage incineration.
[0011] Furthermore, the furnace wall is located between the combustion chamber and the slag chamber to form an overhead cavity, grates are installed between the combustion chamber, the slag chamber and the overhead cavity respectively, and a chimney is arranged on the top of the furnace wall.
[0012] Through the above technical scheme, the overhead cavity is arranged below the combustion cavity, and a combustion nozzle with an ignition device and an air supply pipe can be placed therein to ignite natural gas for garbage incineration. The air supply pipe ensures sufficient oxygen. The separation design can keep a distance between the combustion nozzle and the garbage. The garbage burns above the grate to prevent the combustion nozzle from being suffocated by the solid garbage that suddenly enters. The generated smoke will be discharged from the chimney, and the generated slag will fall into the slag cavity due to its reduced volume, thereby preventing the slag from accumulating in the combustion cavity and affecting the flame generated by the combustion nozzle from directly contacting the garbage, thereby improving the garbage incineration efficiency and ensuring the utilization rate of the fuel.
[0013] Furthermore, a slag discharge channel is provided in the middle of the sealing door located at the opening of the slag chamber, and the slag discharge channel connects the opening of the slag chamber with the second conveyor in series, and a sealing flap is provided in the slag discharge channel.
[0014] Through the above technical scheme, the slag discharge channel runs through the sealing door and is opened in the middle of the sealing door, and the highest point of the slag discharge channel is not higher than the lowest point of the slag chamber opening, thereby ensuring that the slag is discharged from the slag chamber smoothly. The sealing flap in the sealing door can block the slag discharge channel when slag is not discharged, thereby reducing the waste of heat overflowing from the slag discharge channel, and also reducing the impact of high temperature on conveyor two, thereby ensuring that the working temperature of conveyor two is within a reasonable range.
[0015] Furthermore, the outer box is provided with a discharge shell installed through the lowest part of the box body, the highest part of the discharge shell is conductively connected to the box body, and the lowest part of the discharge shell is conductively connected to the conveyor.
[0016] Through the above technical scheme, the bottom of the box is high in front and low in the back, which can ensure that the garbage to be incinerated in the box can slide smoothly to the first position of the conveyor. The discharge shell passes through the outer box and the rear side wall of the box, and is not higher than the bottom of the box, which ensures that the garbage to be incinerated can smoothly enter the conveyor. The bottom of the box is thick in front and thin in the back, the temperature of the ashtray is high in the front and low in the back, and the special-shaped bottom of the box can reduce the probability of heat deformation and ensure smooth conduction of the drainage hole.
[0017] Furthermore, the bottom surface of the box body is installed with equidistantly arranged lining plates, a dispersion plate is arranged between the lining plates and the top surface of the ashtray, and fins are fixedly installed on the vertical outer wall of the box body at the end of the lining plates.
[0018] Through the above technical scheme, the lining plates are arranged equidistantly front and back, and equidistant gaps are left. The dispersion plates are divided into upper and lower layers. Slits are provided between the dispersion plates on the same layer, and horizontal gaps are also left between the upper and lower dispersion plates to ensure that the waste water dripping downwards can be dispersed and contact the ashtray below, to ensure that the slag inside the ashtray is evenly cooled. The water vapor heated and moving upward at the ashtray will be dispersed front and back by the dispersion plates, and guided and dispersed left and right by the lining plates, so that the water vapor is dispersed and moves upward along the bottom of the box to both sides, and finally contacts the fins. The fins are good conductors of heat, so that the water vapor is cooled here and condensed into water droplets and flows downward, heating the box more evenly and covering a wider range.
[0019] Furthermore, a top cover is hingedly installed at the top opening of the outer box, an embedding opening is opened at the bottom of the box body, a bottom plate is detachably installed in the embedding opening, and a vertical micro hole is opened in the middle of the bottom plate.
[0020] Through the above technical solution, if the water content in the garbage to be incinerated is high and there are many fine particles, it is easy to cause the drainage holes to be blocked. The bottom of the box is replaced with a removable bottom plate. The bottom plate can ensure that the moisture of the garbage to be incinerated flows down smoothly, and it can also be disassembled, cleaned or replaced after blockage, making maintenance more convenient.
[0021] Furthermore, the drainage cavity is located at the bottom of the outer box, a water outlet is provided at the lower part of the vertical side wall of the outer box, the drainage cavity penetrates the vertical side wall of the outer box through the water outlet and is connected to the external pipeline, and a sealing plate is installed at one end of the ashtray away from the conveyor.
[0022] Through the above technical scheme, the moisture in the garbage to be incinerated can be heated and vaporized in the box and can also enter the interlayer. Finally, the excess waste water and water vapor can be discharged from the external pipe of the water outlet to avoid excessive pressure in the interlayer, and connected to the collector for collection to prevent the spread of odor. The sealing plate can reduce the heat loss of the waste slag in the ashtray. The sealing plate seals the rear end of the ashtray and can continuously push the slag as the conveyor 2 pushes the slag, squeezing the waste slag in the ashtray into blocks, which are in full contact with the inner wall of the ashtray, ensuring that the heat of the slag can be fully transferred to the entire side wall of the ashtray. The compressed block waste slag is more convenient for centralized treatment.
[0023] Furthermore, the blocking plate includes a vertical plate, the lower part of which is hingedly assembled with the outer wall of the outer box, the bottom end of the vertical plate is rotatably mounted with a horizontal plate, one end of the horizontal plate away from the vertical plate is connected to a telescopic cylinder, and the telescopic cylinder is fixedly connected to the outer box.
[0024] Through the above technical scheme, the vertical plate directly blocks the rear end opening of the ashtray and can swing backward around the rotating shaft below. The rotating shaft is fixed at the vertical outer wall of the outer box, which improves the stable rotation limit of the vertical plate. When opening, the telescopic cylinder is shortened and the bottom end of the vertical plate is pulled by the horizontal plate to a horizontal state. The vertical plate extends a distance to the rear of the outer box to guide the slag. When the slag is taken out of the ashtray backward, the scattered slag can be prevented from falling under the outer box, thereby ensuring thorough cleaning. Rotating the horizontal plate connected between the vertical plate and the telescopic cylinder can ensure that the telescopic cylinder is always in a horizontal state when the vertical plate swings, thereby ensuring the firmness of the installation of the telescopic cylinder.
[0025] Furthermore, a pushing disk is embedded and installed at the inclined bottom surface of the slag cavity, and the pushing disk includes an active disk parallel to the inclined bottom surface and a pushing plate fixed to the top surface of the active disk, and the pushing plates are equidistantly arranged along the radius of the active disk.
[0026] Through the above technical scheme, the pushing disk is provided with an active disc and a pushing plate, and an installation cavity is arranged on the furnace wall below the active disc. A motor can be installed in the installation cavity to drive the pushing disk to rotate. The pushing disk provides centrifugal force for the slag in the slag cavity, thereby ensuring that the slag can be smoothly pushed into the conveyor 2, and preventing the slag from being stuck in the slag cavity due to adhesion.
[0027] Furthermore, the active circular disc of the pushing disc is replaced by an annular chain 1 and chain ring 2, the pushing plate is installed on the top of chain 1 and chain ring 2, the corner position of the slag chamber is provided with an arc-shaped side surface coinciding with the center of the circle of the bending part of chain 1, the inclined bottom surface is provided with a slide groove cooperating with chain 1 and chain ring 2, the inclined bottom surface is provided with a protrusion at the position of the center hole of chain 1, the bottom of chain 1 and chain ring 2 is provided with a limiting ring, and the vertical side walls of chain 1 and chain ring 2 are provided with symmetrically arranged driving wheels and idle wheels.
[0028] The above technical scheme can be used to adapt to the rectangular slag cavity, and the fixed circular active disc can be changed into chain one and chain ring two. Chain one and chain ring two are flexible and can adapt to slag cavities of different sizes. The center of the arc side coincides with the center of the chain one and chain ring two, which can ensure that the push plate always slides along the arc side. A convex block is provided at the hole position of chain one, and the convex block is high in the middle and low around. When the slag falls to the convex block, it will be pushed to the surrounding areas to contact the push plate, thereby eliminating the dead angle at the corner of the slag cavity. The size of the limit ring is larger than the thickness of chain one and chain ring two, thereby preventing chain one and chain ring two from falling off the chute when rotating. At the same time, a driving wheel and an idler wheel are provided as a group, and two groups are respectively arranged on both sides of the straight section of chain one and chain ring two in groups. The driving wheel is rotated by a motor and a belt. The idler wheel ensures that chain one and chain ring two are in stable contact with the driving wheel, thereby ensuring the smooth rotation of the push plate, having stronger adaptability to the pushing of slag, eliminating dead angles and preventing slag from staying in the slag cavity for a long time.
[0029] The beneficial effects of the present invention are as follows:
[0030] (1) The present invention can form a tubular sealed passage between the storage box and the incinerator through the design of the conveyor and the ash canister, thereby ensuring that the transported garbage will not be exposed to the atmosphere. The slag generated during the incineration will be transported to the ash canister to heat the stored garbage, and the heat contained in the slag will be recycled, so that the garbage can be heated and sterilized to avoid deterioration during storage, and the garbage can be preheated to improve the utilization rate of the heat generated by the incineration of garbage and fuel;
[0031] (2) The present invention optimizes the storage box so that the excess water of the waste to be incinerated in the inner box enters the drainage cavity through the bottom surface, thereby slowing down the decomposition and odorization of the biomass waste to be incinerated due to moisture. The ashtray heats and vaporizes the waste water dripping into the drainage cavity from the inner box. After passing through the dispersion plate, the water vapor evenly contacts the outer wall of the inner box to condense and release heat, thereby further improving the uniformity and efficiency of heating the waste.
[0032] (3) The present invention improves the storage box, and the sealing plate seals the rear end of the ashtray. As the conveyor 2 continues to push the slag, the waste slag in the ashtray is squeezed and compacted, and is in full contact with the inner wall of the ashtray, ensuring that the heat of the slag can be fully transferred to the entire side wall of the ashtray, thereby improving the heat recovery efficiency. The vertical plate is pulled to a horizontal state and extends a certain distance to the rear of the outer box to guide the slag, making it more convenient to clean the waste slag.

[0044] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0045] like Figure 1-Figure 10As shown, this embodiment provides a garbage storage device for a garbage power plant, including a storage box 1, which is used to temporarily store garbage to be incinerated. If it is mixed garbage mixed with biomass garbage, it will inevitably deteriorate and produce odor during storage. When incineration, it is transported to the incinerator 3 using a cart or a hanging basket. During the process, the garbage is exposed to the atmosphere for a long time, resulting in poor air quality in the storage and incineration space. In view of the actual problems caused by garbage storage in garbage power plants, the storage equipment is optimized, referring to Figure 1 The storage box 1 is connected to the incinerator 3 through the conveyor 1 2 and the conveyor 2 4. The conveyor 1 2 and the conveyor 2 4 use a spiral auger conveyor, which can form a tubular sealed passage between the storage box 1 and the incinerator 3 and provide a pushing force to prevent garbage from being blocked in the conveying path;
[0046] For incinerator 3, used for burning garbage, see Figure 3 The incinerator 3 includes a furnace wall 31, which is formed by stacking refractory bricks. The furnace wall 31 is surrounded by a combustion chamber 32 and a slag chamber 34 arranged up and down. The garbage is incinerated in the combustion chamber 32. The openings of the combustion chamber 32 and the slag chamber 34 are respectively provided with sealing doors 37, which can ensure that the combustion is carried out in a limited space, which is safe and efficient, and can reduce heat loss. The bottom surface of the slag chamber 34 is set as an inclined bottom surface 36 with a height inclined downward toward the opening. The generated slag will fall into the slag chamber 34 and slide forward along the inclined bottom surface 36 with a lower front and a higher rear, so that the slag can be smoothly moved forward into the conveyor 2 4, so as to be centrally transported to the storage box 1 position;
[0047] Regarding the storage box 1, which is used for temporarily storing the garbage to be incinerated, refer to Figure 4 The storage box 1 includes an outer box 11 and an inner box 8. Both the outer box 11 and the inner box 8 are opened upward. The top cover 12 of the outer box 11 can seal the space inside the inner box 8. The inner diameter of the top opening end of the inner box 8 is increased to fix and block the top opening of the outer box 11. An interlayer 19 is formed between the outer wall of the inner box 8 and the inner wall of the outer box 11. The inner box 8 can store the garbage to be incinerated. An ash tube 14 is provided at the bottom of the outer box 11. The high-temperature slag transported will enter the ash tube 14, and the ash tube 14 will be heated and heated by using the large amount of heat contained in the slag. In addition, the body of the inner box 8 A drainage hole 82 connected to the interlayer 19 is provided on the bottom surface of 81, which can discharge the excess water contained in the garbage downwards. The inner box 8 is located above the ashtray 14. The heated ashtray 14 heats the air and water inside the interlayer 19, and then transfers it to the entire outer wall of the inner box 8, heats and sterilizes the garbage, and preheats it. A drainage cavity 15 is provided at the bottom edge of the outer box 11, which can discharge excess waste water and prevent the ashtray 14 from being submerged in waste water. The cooled slag can be further processed to improve the heat utilization rate of the garbage and optimize the temperature environment of the factory.
[0048] In a further embodiment, in order to ensure that waste incineration completely improves fuel utilization, refer to Figure 3 The furnace wall 31 is located between the combustion chamber 32 and the slag chamber 34 to form an overhead chamber 33. The overhead chamber 33 is arranged below the combustion chamber 32, and a combustion nozzle with an ignition device and an air supply pipe can be placed to ignite natural gas for garbage incineration. The air supply pipe ensures sufficient oxygen. Grates 35 are respectively installed between the combustion chamber 32, the slag chamber 34 and the overhead chamber 33. The separation design can leave a distance between the combustion nozzle and the garbage. The garbage burns above the grate 35 to prevent the combustion nozzle from being suffocated by the solid garbage that suddenly enters. The generated smoke will be discharged from the chimney, and the generated slag will fall into the slag chamber 34 due to its reduced volume, avoiding the slag accumulation in the combustion chamber 32 to affect the flame generated by the combustion nozzle to directly contact the garbage, thereby improving the garbage incineration efficiency and ensuring the utilization rate of the fuel. A chimney is arranged on the top of the furnace wall 31 to lead out the high-temperature smoke for heat recovery.
[0049] In a further embodiment, referring to Figure 1 and Figure 3 A slag discharge channel 38 is provided in the middle of the sealed door 37 at the opening of the slag chamber 34. The slag discharge channel 38 runs through the sealed door 37 and is opened in the middle of the sealed door 37. The highest point of the slag discharge channel 38 is not higher than the lowest point of the opening of the slag chamber 34, so as to ensure that the slag is discharged from the slag chamber 34 smoothly. The slag discharge channel 38 connects the opening of the slag chamber 34 with the conveyor 24 in series. A sealing flap is provided in the slag discharge channel 38, and the sealing flap in the sealed door 37 can be rotated to block the slag discharge channel 38 when slag is not discharged, so as to reduce the waste of heat from the slag discharge channel 38 and the influence of high temperature on the conveyor 24, so as to ensure that the working temperature of the conveyor 24 is within a reasonable range. When slag discharge is required, the sealing flap can be rotated to reset and the slag discharge channel 38 can be connected. The structure can be manually ensured to be stable, or the motor can be used for electric control to improve the convenience of operation.
[0050] In a further embodiment, referring to Figure 2 and Figure 4The outer wall of the bottom end of the box body 81 is horizontal front to back, while the inner wall of the bottom end of the box body 81 is high front and low back, that is, the bottom of the box body 81 is thick in front and thin in back (not shown in the figure, but according to the text description, the bottom shape of the box body 81 can be clearly understood). The outer box 11 is located at the lowest part of the box body 81 and is penetrated by a discharge shell 13. The highest point of the discharge shell 13 is conductively connected with the box body 81 and is not higher than the bottom surface of the box body 81. The lowest point of the discharge shell 13 is conductively connected with the conveyor 2 to ensure that the incinerated garbage enters the conveyor 2 smoothly. The discharge shell 13 penetrates the outer box 11 and the rear side wall of the box body 81. The bottom of the box body 81 is thick in front and thin in back. Because the ashtray 14 takes in slag at the front and discharges slag at the rear, the temperature of the ashtray 14 is high at the front and low at the rear. The bottom surface of the special-shaped box body 81 can be thickened at high temperature to improve the mechanical strength, reduce the probability of thermal deformation, and ensure smooth conduction of the drainage hole 82.
[0051] In a further embodiment, referring to Figure 5 and Figure 7 The bottom surface of the box body 81 is installed with equidistantly arranged lining plates 17. The lining plates 17 are equidistantly arranged front and back, and there are equidistant gaps. A dispersion plate 18 is separated from the top surface of the liner plate 17 and the ashtray 14. The dispersion plate 18 is divided into two layers, the upper and lower layers. There are slits between the dispersion plates 18 on the same layer, and there is a horizontal gap between the upper and lower layers of the dispersion plates 18. When the wastewater in the box body 81 drips downward, the wastewater dripping downward can flow forward and backward along the dispersion plate 18 and disperse, and evenly contact the ashtray 14 below, ensuring that the ashtray 14 is evenly dispersed. The slag inside the cylinder 14 is cooled evenly. When the waste water is heated and vaporized, the vertical outer wall of the box body 81 at the end of the lining 17 is fixedly installed with fins 83. The water vapor heated and moving upward in the ash cylinder 14 will be dispersed front and back by the dispersion plate 18, and guided and dispersed left and right by the lining 17, so that the water vapor is dispersed upward to both sides along the bottom surface of the box body 81, and finally contacts the fins 83. The fins 83 are good conductors of heat, so that the water vapor is cooled here, condensed into water droplets and flows downward, thereby heating the box body 81 more evenly and covering a larger area.
[0052] In a further embodiment, if the water content in the waste to be incinerated is high and there are many fine particles, it is easy to cause the drainage hole 82 to be blocked. Figure 2 and Figure 7 A top cover 12 is hingedly installed at the top opening of the outer box 11, which can be opened to add garbage to be incinerated, and can also be opened to clean the bottom surface of the box body 81. At the same time, an embedding opening is opened at the bottom of the box body 81, and a bottom plate 84 is detachably installed in the embedding opening. A vertical microhole is opened in the middle of the bottom plate 84. The bottom plate 84 can ensure that the moisture of the garbage to be incinerated flows down smoothly, and can also be lifted from the embedding opening after being blocked and taken out of the box body 81 for quick disassembly, cleaning or replacement, making maintenance more convenient.
[0053] In a further embodiment, in order to ensure that the heat of the slag is fully absorbed and transferred by the ash tube 14, refer to Figure 4 and Figure 6 A blocking plate 9 is installed at one end of the ashtray 14 away from the conveyor 24. The blocking plate 9 blocks the rear end of the ashtray 14, which can reduce the heat loss of the waste slag in the ashtray 14. As the conveyor 24 continues to push the slag, the waste slag in the ashtray 14 can be squeezed into blocks, which are in full contact with the inner wall of the ashtray 14, ensuring that the heat of the slag can be fully transferred to the entire side wall of the ashtray 14. The compressed block waste slag is more convenient for centralized treatment.
[0054] In a further embodiment, referring to Figure 2 and Figure 6 The drainage chamber 15 is located at the bottom of the outer box 11, and a water outlet is provided at the lower part of the vertical side wall of the outer box 11. The moisture in the incinerated garbage is heated and vaporized in the box body 81 and can also enter the interlayer 19. Finally, the excess waste water and water vapor can be discharged from the external pipe of the water outlet to avoid excessive pressure in the interlayer 19. The drainage chamber 15 passes through the vertical side wall of the outer box 11 through the water outlet and is connected to the external pipe, and is connected to the collector for collection to prevent the spread of odor.
[0055] In a further embodiment, a specific blocking plate 9 is provided for blocking the rear end of the ashtray 14, referring to Figure 7 The blocking plate 9 includes a vertical plate 91, which directly blocks the rear end opening of the ashtray 14 and can swing backward around the rotating shaft below. The rotating shaft is fixed to the vertical outer wall of the outer box 11, so that the lower part of the vertical plate 91 is hingedly assembled with the outer wall of the outer box 11, and the vertical plate 91 is stabilized and limited in rotation. At the same time, a horizontal plate 92 is rotatably installed at the bottom end of the vertical plate 91, and a telescopic cylinder 93 is connected to the end of the horizontal plate 92 away from the vertical plate 91. When closing, the vertical plate 91 seals the rear end of the ashtray 14, and when opening, the telescopic cylinder 93 shortens through The horizontal plate 92 pulls the bottom end of the vertical plate 91 to pull the vertical plate 91 to a horizontal state. The vertical plate 91 extends a distance to the rear of the outer box 11 to guide the slag. When the slag is taken out of the ashtray 14 backwards, the scattered slag can be prevented from falling under the outer box 11, thereby ensuring thorough cleaning. The telescopic cylinder 93 is fixedly connected to the outer box 11, and the horizontal plate 92 connected between the vertical plate 91 and the telescopic cylinder 93 is rotatably connected to ensure that the telescopic cylinder 93 is always in a horizontal state when the vertical plate 91 swings, thereby ensuring the firmness of the installation of the telescopic cylinder 93.
[0056] In a further embodiment, in order to prevent the slag from being blocked in the slag cavity 34 due to adhesion, refer to Figure 8A pushing disk 5 is embedded and installed at the inclined bottom surface 36 of the slag cavity 34. The pushing disk 5 includes an active disk parallel to the inclined bottom surface 36 and a pushing plate 51 fixed to the top surface of the active disk. An installation cavity is set on the furnace wall 31 below the active disk. A motor can be installed in the installation cavity to drive the pushing disk 5 to rotate. The pushing plates 51 are arranged equidistantly along the radius of the active disk. The pushing disk 5 provides centrifugal power for the slag in the slag cavity 34 through the pushing plate 51, ensuring that the slag can be smoothly pushed out of the opening at the front end of the slag cavity 34 and sent to the conveyor 4.
[0057] In a further embodiment, in order to adapt to the rectangular slag chamber 34 of different sizes, refer to Fig. 9 and Fig.10 , the active disc of the push disc 5 is replaced by an annular chain 1 52 and a chain ring 2 53. The chain 1 52 and the chain ring 2 53 are flexible and can be bent into approximately rectangular shapes of different lengths and widths to adapt to slag chambers 34 of different sizes. The push plate 51 is installed on the top of the chain 1 52 and the chain ring 2 53. The corners of the slag chamber 34 are provided with arc-shaped side surfaces 39 coinciding with the center of the circle at the bending point of the chain 1 52, which can ensure that the push plate 51 always slides against the arc-shaped side surfaces 39 at the corners. At the same time, the inclined bottom surface 36 is located at the middle hole position of the chain 1 52 and is provided with a protrusion 6. The protrusion 6 is high in the middle and low around. When the slag falls to the position of the protrusion 6, it will be pushed to the surroundings to contact the push plate 51, eliminating the dead angle at the corners of the slag chamber 34. It should be noted that a limit ring 54 is provided at the bottom of the chain 1 52 and the chain ring 2 53, and the inclined bottom surface 36 is provided with a The size of the limit ring 54 of the slide 7 matched with the chain 1 52 and the chain ring 2 53 is larger than the thickness of the chain 1 52 and the chain ring 2 53, and the embedded installation method is used to prevent the slag from entering the slide 7 and prevent the chain 1 52 and the chain ring 2 53 from falling off the slide 7 when rotating. In terms of power, the vertical side walls of the chain 1 52 and the chain ring 2 53 are provided with symmetrically arranged driving wheels 56 and idler wheels 57. A driving wheel 56 and an idler wheel 57 are set as a group, and two groups are provided, which are respectively arranged in groups on both sides of the straight sections of the chain 1 52 and the chain ring 2 53. The driving wheel 56 is rotated by the motor and the belt. The idler wheel 57 ensures that the chain 1 52 and the chain ring 2 53 are in stable contact with the driving wheel 56, ensuring the smooth rotation of the push plate 51, and having stronger adaptability to the pushing of slag, eliminating dead angles to prevent the slag from remaining in the slag cavity 34 for a long time.
[0058] The working principle of this embodiment is as follows:
[0059] The excess water of the waste to be incinerated in the inner box 8 enters the drainage cavity 15 through the drainage hole 82, slowing down the decomposition and odorization of the waste to be incinerated due to moisture;
[0060] The inner box 8 conveys the garbage to be incinerated to the combustion chamber 32 through the conveyor 2, and the garbage to be incinerated is ignited and incinerated in the combustion chamber 32, and the generated slag falls downward into the slag chamber 34, so as to prevent the slag from accumulating in the combustion chamber 32 and affecting the combustion of the garbage;
[0061] Under the guidance of the inclined bottom surface 36, the furnace slag chamber 34 slides down to the position of the conveyor 24, and the slag chamber 34 pushes the accumulated slag into the ash tube 14 through the conveyor 24, and performs automatic slag discharge, thereby improving the automatic degree of garbage incineration;
[0062] The heat of the slag is transferred through the ash can 14 to heat the inner box 8 and the interlayer 19. The ash can 14 heats and vaporizes the waste water dripping into the drainage chamber 15 from the inner box 8. The water vapor contacts the outer wall of the inner box 8 to condense and release heat, and heats and dries the waste to be incinerated in the inner box 8, so that the waste to be incinerated is heated and sterilized to further reduce the corruption phenomenon.
[0063] The slag in the ash tube 14 heats the inner box 8 through waste water, so that the garbage can be preheated before incineration, the heat of the slag can be recycled, the energy consumption during garbage incineration can be reduced, the temperature of the slag that needs to be transported can be reduced, and the temperature environment of the factory building can be optimized.
[0064] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.
