DETAILED DESCRIPTION

[0029] The application will be further described below with reference to the accompanying drawings and embodiments. Figures 1-7

[0030] Embodiment one

[0031] The embodiment discloses a drying reactor for rapid drying of domestic waste.

[0032] With reference to Figures 1 to 3 The drying reactor for rapid drying of domestic waste comprises a main control room 1, a ventilation room 2 and a biological drying room 3, the ventilation room 2 and the biological drying room 3 are adjacent to each other on the left and right, the main control room 1 is arranged at the top of the ventilation room 2 and the biological drying room 3, and the structure and function of the main control room 1, the ventilation room 2 and the biological drying room 3 are prior art, so that they will not be described in detail. In the application, the biological drying room 3 comprises a drying box 4, a turning structure, a turning driving element, a lifting driving element and a hydraulic system. ​

[0033] With reference to Figure 1 , Figure 2 and Figure 6 , the drying box 4 is arranged on the ground of the biological drying chamber 3, and the drying box 4 is a top-opened trapezoidal box body, which comprises a bottom plate 41, two inclined plates 42 and two vertical plates 43. The bottom plate 41 is in a rectangular plate shape. The bottom portions of the two inclined plates 42 are respectively connected to the two sides in the width direction of the bottom plate 41. The top portions of the two inclined plates 42 are both inclined away from the bottom plate 41. The two vertical plates 43 are respectively connected to the two ends in the length direction of the bottom plate 41 and are respectively connected to the two ends of the two inclined plates 42. Through the above design, the width of the drying box 4 gradually increases from the bottom to the top. In addition, the same as the prior art, the ventilation corridor is arranged between the ventilation chamber 2 and the biological drying chamber 3, and the ventilation corridor also extends into the bottom of the drying box 4 to realize oxygen supply and cooling of the garbage in the drying box 4 by blowing.

[0034] With reference to Figure 2 and Figure 3 , the two ends in the length direction of the drying box 4 are provided with lifting parts 5, that is, the two vertical plates 43 are both provided with the lifting parts 5. Specifically, the vertical plate 43 is provided with a vertical strip-shaped hole 431. The lifting part 5 comprises a sliding block 51 and a mounting plate 52. The sliding block 51 is slidingly arranged in the vertical direction in the strip-shaped hole 431. In this embodiment, the strip-shaped hole 431 is a rectangular hole, and the sliding block 51 is a rectangular block. The mounting plate 52 is fixedly connected with the outer end of the sliding block 51, so that the mounting plate 52 and the sliding block 51 are synchronous lifting. In addition, in order to avoid the garbage in the drying box 4 from falling out of the strip-shaped hole 431, the top surface and the bottom surface of the strip-shaped hole 431 are both provided with a vertical insertion slot. The top and bottom of the sliding block 51 are both fixedly connected with a vertical insertion rod 511. The two insertion rods 511 are respectively inserted into the two insertion slots. In this embodiment, the insertion slot is a rectangular slot, and the insertion rod 511 corresponds to a rectangular rod. It should be noted that it is necessary to ensure that the insertion rod 511 above does not come off the insertion slot above when the sliding block 51 slides to the lowest point, and it is necessary to ensure that the insertion rod 511 below does not come off the insertion slot below when the sliding block 51 slides to the highest point. Finally, through the insertion rod 511 and the sliding block 51 which are movable up and down, it is ensured that the strip-shaped hole 431 is always closed to prevent the garbage in the drying box 4 from falling out of the strip-shaped hole 431,

[0035] With reference to Figure 3 and Figure 4, the turning shaft 61 is a round shaft, the length of the turning shaft 61 is longer than the length of the drying box 4, the turning shaft 61 is rotationally arranged between the sliding blocks 51 of the two lifting parts 5, so that the axis of the turning shaft 61 is a horizontal line. Moreover, the two ends of the turning shaft 61 respectively extend to the outer ends of the two sliding blocks 51. The turning surface of the turning structure includes hydraulic control rods 62 and driven telescopic rods 63. In the embodiment, the number of the hydraulic control rods 62 is two, the two hydraulic control rods 62 are arranged on the circumferential surface of the turning shaft 61 along the axis direction of the turning shaft 61, and the two hydraulic control rods 62 are located on the same side of the turning shaft 61. The number of the driven telescopic rods 63 is several, the several driven telescopic rods 63 are arranged on the circumferential surface of the turning shaft 61 along the axis direction of the turning shaft 61, and the several driven telescopic rods 63 are located on the same side of the turning shaft 61. Further, the several driven telescopic rods 63 are located between the two hydraulic control rods 62, and the outer ends of the two hydraulic control rods 62 and the outer ends of the several driven telescopic rods 63 are connected by connecting rods 64. The hydraulic control rods 62, the driven telescopic rods 63 and the connecting rods 64 jointly constitute the turning surface of the turning structure. It should be noted that, in order to ensure that the turning surface is large enough to better turn the garbage in the drying box 4, the two hydraulic control rods 62 need to be as close as possible to the inner side of the two vertical plates 43.

[0036] With reference to Figure 3 , the turning driving part is a motor 7, the motor 7 is fixedly arranged on the mounting plate 52 of one of the lifting parts 5, and the motor 7 is used to control the rotation of the turning structure. Specifically, the mounting plate 52 of the lifting part 5 is also provided with a speed reducer 71, the motor 7 is located below the speed reducer 71, and the output shaft of the motor 7 is connected with the input shaft of the speed reducer 71. Further, the output shaft of the speed reducer 71 is coaxially connected with a small bevel gear, and the outer end of the turning shaft 61 is coaxially connected with a large bevel gear. The small bevel gear is engaged with the large bevel gear, so that the output shaft of the motor 7 drives the turning structure to turn after two times of speed reduction, so as to turn the garbage in the drying box 4.

[0037] With reference to Figure 3 In the embodiment, the lifting driving part is an oil cylinder 8, the oil cylinder 8 is used to control the lifting of the turning structure. In the remaining embodiments, the lifting driving part can also be a gas cylinder, a screw mechanism and other driving parts capable of lifting. The oil cylinder 8 is arranged on the ground of the biological drying room 3, and the number of the oil cylinder 8 is two. The two oil cylinders 8 are respectively located on the outer sides of the two vertical plates 43 of the drying box 4. Further, the telescopic end of the oil cylinder 8 is provided with a bearing seat 81, and the two outer ends of the turning shaft 61 are rotationally connected with the bearing seats 81 of the telescopic ends of the two oil cylinders 8. Therefore, the oil cylinder 8 can lift the turning structure without affecting the turning of the turning structure.

[0038] With reference to Figure 3 and Figure 4, the two hydraulic control rods 62 of the turning-up surface are connected with the hydraulic system, so that the turning-up surface is elongated with the supplement of liquid and shortened with the extraction of liquid. Therefore, when the living garbage is treated by the drying reactor, if the amount of garbage in the drying box 4 is large, the turning-up structure is first lifted by the lifting driving element, and then the liquid is supplemented into the turning-up surface by the hydraulic system to elongate the turning-up surface, and then the turning-up structure is rotated by the turning-up driving element to turn up the garbage in the drying box 4. If the amount of garbage in the drying box 4 is small, the turning-up structure is first lowered by the lifting driving element, and then the liquid is extracted from the turning-up surface by the hydraulic system to shorten the turning-up surface, and then the turning-up structure is rotated by the turning-up driving element to turn up the garbage in the drying box 4. Since the amount of liquid is reduced after the turning-up surface is shortened, the weight of the turning-up surface after being shortened is lower, so that the turning-up driving element consumes less energy when driving the turning-up structure after the turning-up surface is shortened. Therefore, the drying reactor for rapid drying of living garbage can adjust the turning-up structure according to the actual amount of garbage, so as to reduce energy consumption under the condition of small amount of garbage, so as to achieve the energy saving effect.

[0039] Referring to Figures 3 to 5 , the hydraulic system comprises a hydraulic cylinder 9, a piston 91 and a connecting pipe 92, the hydraulic cylinder 9 is arranged on the ground of the biological drying chamber 3 and located outside one of the vertical plates 43 of the drying box 4, the hydraulic cylinder 9 is provided with a first liquid cavity, the piston 91 is movably arranged in the hydraulic cylinder 9 and used for adjusting the size of the first liquid cavity, and the first liquid cavity is connected with the two hydraulic control rods 62 of the turning-up surface through the connecting pipe 92. Further, the piston 91 is arranged in the hydraulic cylinder 9 in a lifting manner, the first liquid cavity is formed between the top of the hydraulic cylinder 9 and the piston 91, the first liquid cavity is reduced by the upward movement of the piston 91, and then the liquid is supplemented into the hydraulic control rods 62 of the turning-up surface, and the first liquid cavity is increased by the downward movement of the piston 91, and then the liquid is extracted from the hydraulic control rods 62 of the turning-up surface. It should be noted that the bottom of the hydraulic cylinder 9 is provided with an air hole to ensure that the air pressure below the piston 91 is always balanced with the atmospheric pressure, so as to facilitate the lifting of the piston 91. In addition, the piston 91 is lifted synchronously with the turning-up structure, so that the hydraulic system can automatically supplement the liquid into the turning-up surface with the lifting of the turning-up structure, and can automatically extract the liquid from the turning-up surface with the lowering of the turning-up structure. Therefore, the lifting of the turning-up structure of the drying reactor for rapid drying of living garbage and the stretching and shrinking of the turning-up surface are always synchronous, so as to conveniently adjust the turning-up structure according to the change of the actual amount of garbage, and conveniently achieve the energy saving effect.

[0040] Referring to Figures 3 to 5The hydraulic control rod 62 comprises a first guide rod 621 and a first sleeve 622, and the driven telescopic rod 63 comprises a second guide rod 631 and a second sleeve 632, the first guide rod 621 and the second guide rod 631 are arranged on the circumferential surface of the rotating shaft 61 along the axial direction of the rotating shaft 61, the first sleeve 622 and the second sleeve 632 are movably sleeved on the first guide rod 621 and the second guide rod 631 respectively, so as to realize the telescopic movement of the hydraulic control rod 62 and the driven telescopic rod 63, and the connecting rod 64 is connected between the first sleeve 622 and the second sleeve 632, so as to realize the synchronous telescopic movement of the hydraulic control rod 62 and the driven telescopic rod 63. Further, the second liquid cavity is arranged in the hydraulic control rod 62, the second liquid cavity is formed between the first guide rod 621 and the first sleeve 622, and the inner pipeline is arranged between one end of the rotating shaft 61 and the second liquid cavity, and the first liquid cavity, the connecting pipe 92, the inner pipeline and the second liquid cavity are sequentially communicated.

[0041] With reference to Figure 3 and Figure 5 , the connecting pipe 92 is arranged on the hydraulic cylinder 9 in a lifting manner, the connecting pipe 92 is in an L shape, the lower end of the connecting pipe 92 extends into the first hydraulic cavity of the hydraulic cylinder 9 and is fixed relative to the piston 91, and the upper end of the connecting pipe 92 is located outside the hydraulic cylinder 9 and is rotationally connected with the end of the rotating shaft 61. When the lifting driving part controls the lifting of the pile turning structure, the connecting pipe 92 is lifted relative to the hydraulic cylinder 9, and when the pile turning driving part controls the rotation of the pile turning structure, the connecting pipe 92 and the rotating shaft 61 of the pile turning structure relatively rotate.

[0042] With reference to Figure 3 and Figure 5 , the top of the piston 91 is fixedly connected with the third guide rod 911, the upper end of the third guide rod 911 penetrates through the top of the hydraulic cylinder 9, and the piston 91 drives the third guide rod 911 to be arranged on the hydraulic cylinder 9 in a lifting manner. Further, the piston 91 is fixedly connected with the mounting plate 52 of the lifting part 5 through the third guide rod 911, so as to realize the synchronous lifting of the piston 91 and the pile turning structure, and the lower end of the connecting pipe 92 is fixedly connected through the third guide rod 911, so as to realize the relative fixation of the piston 91 and the connecting pipe 92.

[0043] With reference to Figure 3 and Figure 5, the connecting pipe 92 and the third guide rod 911 all pass through the top of the hydraulic cylinder 9, and the top of the hydraulic cylinder 9 is also provided with a liquid supplementing opening 93, which is detachably provided with a cylinder plug. By pulling out the cylinder plug, liquid can be supplemented into the first hydraulic cavity in the hydraulic cylinder 9. In addition, the top edge of the hydraulic cylinder 9 is provided with a closed recovery frame 94, which surrounds the connecting pipe 92, the third guide rod 911 and the liquid supplementing opening 93. During long-term use, the connecting pipe 92 and the third guide rod 911 will gradually bring out liquid from the first hydraulic cylinder 9 to the top surface of the hydraulic cylinder 9. The recovery frame 94 can prevent the liquid from overflowing from the edge of the top surface of the hydraulic cylinder 9 and facilitate the recovery of the liquid brought out to the top surface of the hydraulic cylinder 9 through the liquid supplementing opening 93.

[0044] With reference to Figure 6 , the inner bottom surface of the drying box 4 and the two inner surfaces in the width direction are both provided with a round corner. The round corner is arranged to reduce the blind area of the turning pile surface of the turning pile structure during the turning pile process, so as to achieve a more sufficient turning pile effect.

[0045] With reference to Figure 4 , in order to make the turning pile structure more fully turn the garbage in the drying box 4, it is necessary to ensure that the gap between the adjacent hydraulic control rods 62 and the driven telescopic rods 63 and the gap between the adjacent two driven telescopic rods 63 are small enough, so as to reduce the situation that the garbage passes through the gap of the turning pile structure during the turning pile process.

[0046] Example two

[0047] With reference to Figure 4 and Figure 7 , the difference from example one is that a spring 65 is connected between the first guide rod 621 and the first sleeve 622. On the one hand, the arrangement of the spring 65 can avoid the first sleeve 622 from easily separating from the first guide rod 621, and make the hydraulic control rod 62 have a tendency to automatically contract. On the other hand, the arrangement of the spring 65 can make the turning pile surface of the turning pile structure have a buffering effect during the turning pile process, reduce the hard contact, and achieve a better protection effect.

[0048] Example three

[0049] With reference to Figure 8 , the difference from example one is that a turning pile bucket 10 is connected between the adjacent two second sleeves 632 and between the adjacent second sleeve 632 and the first sleeve 622. The opening of the turning pile bucket faces the rotation direction of the turning pile structure. By arranging the turning pile bucket 10, the turning pile structure can more fully turn the garbage in the drying box 4, reduce the situation that the garbage passes through the gap of the turning pile structure, and thus improve the turning pile effect.

[0050] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, and thus: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
