[0025] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0026] First embodiment: Please refer to Figures 1 to 3 , wherein Figure 1 is the overall structural diagram of the first embodiment of the present invention, Figure 2 is the overall cross-sectional view of the first embodiment of the present invention, Figure 3 is of the present invention Figure 2Local structure enlarged view at position A. The present invention provides a vertical driving grate system for waste incineration, including a furnace body 101 and an incineration component. The incineration component includes a feeding channel 102, a slag discharging channel 103, a support frame 104, a sealing plate 105, a plurality of static grates 106, a plurality of moving grates 107, a plurality of fixing plates 108, a plurality of first bolts 109, a plurality of second bolts 110, a driving unit, a lifting unit, two door panels 111 and two handles 114. The furnace body 101 has a reaction chamber 112 and a disassembly chamber 113. The driving unit includes a first motor 115, a first rotating shaft 116, a swing frame 117 and a plurality of cylinders 118. The lifting unit includes a second motor 119, a lead screw 120 and a lead screw nut 121.

[0027] For this specific embodiment, waste enters the reaction chamber 112 through the feeding channel 102 for incineration. At the same time, the first motor 115 is started to drive the first rotating shaft 116 to rotate, driving the swing frame 117 to rotate. Through the connection of the first cylinder 118, the moving grate 107 is driven to move up and down, continuously forming a height difference with the static grate 106, thereby continuously conveying the waste and playing a role in stirring and dispersing. At the same time, the first cylinder 118 can be telescoped, so as to adjust the movement range of each different moving grate 107, so that the relative positions between the grates are adjustable, achieving the effect of adjusting the movement range and movement rhythm of each moving grate 107 to be different, maximizing the incineration effect. Finally, after the incineration is completed, it is discharged from the slag discharging channel 103. When the grates need to be disassembled and maintained, the second motor 119 is started to drive the lead screw 120 to rotate. The lead screw 120 is adapted to the lead screw nut 121, thereby driving the support frame 104 to move downwards, so that the plurality of static grates 106 and the plurality of moving grates 107 move down to the disassembly chamber 113. At this time, by opening the door panel 111, the first bolt 109 and the second bolt 110 can be unscrewed to complete the disassembly of the grates.

[0028] Among them, the feeding channel 102 and the slag discharge channel 103 are both connected to the furnace body 101 and are respectively located on both sides of the furnace body 101. The furnace body 101 has a reaction chamber 112 and a disassembly chamber 113. The support frame 104 is placed inside the disassembly chamber 113. The sealing plate 105 is fixedly connected to the support frame 104 and is located above the support frame 104. The sealing plate 105 is located between the reaction chamber 112 and the disassembly chamber 113. A plurality of static grate bars 106 are all fixed above the sealing plate 105 through corresponding first bolts 109. A plurality of moving grate bars 107 are all slidably connected to the sealing plate 105. One ends of the plurality of moving grate bars 107 are respectively connected to the fixing plate 108 through corresponding second bolts 110. The driving unit is arranged inside the support frame 104. A plurality of fixing plates 108 are all arranged on the driving unit. The lifting unit is arranged inside the disassembly chamber 113 and is located on one side of the support frame 104. Both door panels 111 are rotatably connected to the furnace body 101. Garbage enters the reaction chamber 112 through the feeding channel 102 for incineration. At the same time, the driving unit is started to drive the moving grate bars 107 to move up and down in the reaction chamber 112, continuously forming a height difference with the static grate bars 106, so as to continuously convey the garbage, playing a role in stirring and dispersing. Finally, after the incineration is completed, it is discharged from the slag discharge channel 103. When the grate bars need to be disassembled and maintained, the lifting unit drives the support frame 104 and the sealing plate 105 to move downwards, so that the plurality of static grate bars 106 and the plurality of moving grate bars 107 move down to the disassembly chamber 113. At this time, by opening the door panels 111, the first bolts 109 and the second bolts 110 can be unscrewed to complete the disassembly of the grate bars. Thus, after the grate bars are used for a long time, the grate bars can be quickly taken out and disassembled from the reaction chamber 112, and at the same time, reliable installation stability can be provided. Compared with the traditional grate bars, it is more convenient for the staff to maintain and operate.

[0029] Secondly, the two handles 114 are respectively rotatably connected to the corresponding door panels 111 and are located on one side of the door panels 111. The handles 114 can facilitate opening the door panels 111.

[0030] Meanwhile, the first motor 115 is fixedly connected to the support frame 104 and is located above the support frame 104. One end of the first rotating shaft 116 is fixedly connected to the output end of the first motor 115, and the other end of the first rotating shaft 116 is rotatably connected to the inner wall of the disassembly chamber 113. The swing frame 117 is fixedly connected to the first rotating shaft 116 and is sleeved on the outer surface wall of the first rotating shaft 116. A plurality of the cylinders 118 are all rotatably connected to the swing frame 117, and the output ends of the plurality of the cylinders 118 are respectively rotatably connected to the corresponding fixing plates 108. When the first motor 115 is started, it drives the first rotating shaft 116 to rotate, drives the swing frame 117 to rotate, and through the connection of the first cylinder 118, it further drives the moving grate 107 to move up and down. At the same time, the first cylinder 118 can be telescoped, so as to adjust the movement ranges of the different moving grates 107, so that the relative positions between the grates are adjustable, achieving the effect of adjusting the movement ranges and movement beats of each moving grate 107 to be different, and maximizing the incineration effect.

[0031] In addition, the second motor 119 is fixedly connected to the furnace body 101 and is located on the inner bottom wall of the disassembly chamber 113. One end of the lead screw 120 is fixedly connected to the output end of the second motor 119, and the other end of the lead screw 120 is rotatably connected to the inner top wall of the disassembly chamber 113. The lead screw nut 121 is fixedly connected to the support frame 104 and is located on one side of the support frame 104. The lead screw 120 and the lead screw nut 121 are mutually adapted. When the second motor 119 is started, it drives the lead screw 120 to rotate, and the lead screw 120 is adapted to the lead screw nut 121, so as to drive the support frame 104 to move downward.

[0032] When using a vertical driving grate system for waste incineration according to this embodiment, waste enters the reaction chamber 112 through the feeding channel 102 for incineration. At the same time, the first motor 115 is started to drive the first rotating shaft 116 to rotate, driving the swing frame 117 to rotate. Through the connection of the first cylinder 118, the moving grate 107 is driven to move up and down, continuously forming a height difference with the static grate 106, thereby continuously conveying waste and playing a role in stirring and dispersing. At the same time, the first cylinder 118 can be telescoped to adjust the movement range of each different moving grate 107, so that the relative positions between the grates are adjustable, achieving the effect of adjusting the movement range and movement rhythm of each moving grate 107 to be different, maximizing the incineration effect. Finally, after incineration is completed, it is discharged from the slag discharge channel 103. When the grate needs to be disassembled and maintained, the second motor 119 is started to drive the lead screw 120 to rotate. The lead screw 120 is adapted to the lead screw nut 121, thereby driving the support frame 104 to move downwards, so that multiple static grates 106 and multiple moving grates 107 move down to the disassembly chamber 113. At this time, by opening the door panel 111, the first bolt 109 and the second bolt 110 can be unscrewed to complete the disassembly of the grate. Through the above structural settings, after the grate has been used for a long time, the grate can be quickly taken out and disassembled from the reaction chamber 112, and at the same time, reliable installation stability can be provided. Compared with the traditional grate, it is more convenient for the staff to maintain and operate.

[0033] Second Embodiment: Based on the first embodiment, please refer to Figures 4 to 6 , where Figure 4 is the overall cross-sectional view of the second embodiment of the present invention, Figure 5 is the Figure 4 local enlarged view of the structure at B of Figure 6 is the structural schematic diagram of the third bolt of the present invention. The present invention provides a vertical driving grate system for waste incineration, which further includes a plurality of grate angle adjustment components. The grate angle adjustment components include a rotating plate 201, a baffle 202, a slider 203, a third bolt 204, and a blade 209.

[0034] For this specific embodiment, rotate the rotating plate 201 to an appropriate angle. At the same time, due to the rotation of the rotating plate 201, the baffle 202 is taken out of the groove 205, and the slider 203 slides in the chute 206. Then, the baffle 202 can block the area below the rotating plate 201 to prevent garbage from entering and accumulating below the rotating plate 201. Finally, rotate the third bolt 204 to cooperate with the threaded hole 208. After tightening, the third bolt 204 abuts against the baffle 202. After the baffle 202 is fixed, the slider 203 cannot slide in the chute 206, thereby fixing the rotating plate 201. At the same time, the garbage is conveyed above the baffle 202 and rubs when passing through the blade 209, playing a role in cutting and dispersing.

[0035] Among them, a plurality of the grate angle adjustment components are arranged on the corresponding moving grate 107 and the static grate 106. The grate angle adjustment component can adjust the angle of the working surface of the grate, so as to adapt to the conveying of materials with different stacking angles.

[0036] Secondly, the rotating plate 201 is rotatably connected to the moving grate 107 and is located above the moving grate 107. The moving grate 107 has a groove 205, the baffle 202 is located inside the groove 205, the rotating plate 201 has a chute 206, the slider 203 is slidably connected to the chute 206, one end of the baffle 202 is rotatably connected to the slider 203 and is located below the slider 203. The moving grate 107 has a mounting hole 207 and a threaded hole 208. The third bolt 204 is located inside the mounting hole 207, the third bolt 204 is mutually adapted to the threaded hole 208, and one end of the third bolt 204 penetrates through the threaded hole 208 and abuts against the baffle 202. Rotate the rotating plate 201 to an appropriate angle. At the same time, due to the rotation of the rotating plate 201, the baffle 202 is taken out of the groove 205, and the slider 203 slides in the chute 206. Then, the baffle 202 can block the area below the rotating plate 201 to prevent garbage from entering and accumulating below the rotating plate 201. Finally, rotate the third bolt 204 to cooperate with the threaded hole 208. After tightening, the third bolt 204 abuts against the baffle 202. After the baffle 202 is fixed, the slider 203 cannot slide in the chute 206, thereby fixing the rotating plate 201.

[0037] At the same time, the blade 209 is fixedly connected to the rotating plate 201 and is located above the rotating plate 201. The garbage is conveyed above the baffle 202 and rubs when passing through the blade 209, playing a role in cutting and dispersing.

[0038] When using a garbage incineration vertical drive grate system of the present embodiment, the rotating plate 201 is rotated to a suitable angle, and at the same time, the baffle 202 is brought out of the groove 205 due to the rotation of the rotating plate 201, and the slider 203 slides in the slide groove 206, so that the baffle 202 can block the area below the rotating plate 201 to prevent garbage from entering the bottom of the rotating plate 201 and causing accumulation. Finally, the third bolt 204 is rotated to cooperate with the threaded hole 208. After tightening, the third bolt 204 abuts against the baffle 202. After the baffle 202 is fixed, the slider 203 cannot slide in the slide groove 206, thereby fixing the rotating plate 201. At the same time, the garbage is transported above the baffle 202, and friction occurs when passing through the blade 209, which plays a role of cutting and breaking up. Through the above-mentioned structural arrangement, the angle of the working surface of the grate can be adjusted to adapt to the transportation of materials with different accumulation angles.

[0039] Third embodiment: The vertical driven grate system for garbage incineration further includes two sliding assemblies, both of which are arranged inside the furnace body 101. The sliding assembly includes a slide rail 301 and a moving block 302, wherein the slide rail 301 is fixedly connected to the furnace body 101 and is located on the inner side wall of the furnace body 101, one end of the moving block 302 is slidably connected to the slide rail 301, and the other end of the moving block 302 is fixedly connected to the support frame 104 and is located on a side of the support frame 104 away from the screw nut 121.

[0040] Based on the second embodiment, please refer to Figure 7 and Figure 8 ,in Figure 7 is a cross-sectional view of the entire third embodiment of the present invention, Figure 8 The present invention Figure 7 The present invention provides a vertical driven grate system for garbage incineration, which also includes two sliding assemblies, wherein the sliding assemblies include a slide rail 301 and a moving block 302 .

[0041] According to this specific embodiment, when the support frame 104 moves, the moving block 302 slides in the slide rail 301, thereby playing an auxiliary supporting role and reducing shaking during movement, thereby improving the stability of the support frame 104 moving up and down, making the disassembly and installation of the grate safer.

[0042] The two sliding assemblies are both disposed inside the furnace body 101. The sliding assemblies can improve the stability of the support frame 104 in moving up and down, making the removal and installation of the grate safer.

[0043] Secondly, the slide rail 301 is fixedly connected to the furnace body 101 and is located on the inner side wall of the furnace body 101. One end of the moving block 302 is slidably connected to the slide rail 301, and the other end of the moving block 302 is fixedly connected to the support frame 104 and is located on the side of the support frame 104 away from the lead screw nut 121. When the support frame 104 moves, the moving block 302 slides in the slide rail 301, thereby playing a role in auxiliary support and reducing the shaking during movement.

[0044] When using a vertical driving grate system for waste incineration according to this embodiment, when the support frame 104 moves, the moving block 302 slides in the slide rail 301, thereby playing a role in auxiliary support and reducing the shaking during movement. Thus, the stability of the up-and-down movement of the support frame 104 can be improved, making the disassembly and installation of the grate safer.
