In addition, existing kitchen waste drying equipment also generally has the problem of uneven drying. This is mainly due to the fact that during the drying process, the garbage is piled up or stacked in the equipment, and the heat source is unevenly distributed, which greatly reduces the drying effect of the kitchen waste.

[0022] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0023] Example 1, as Figure 1-6 As shown, a continuous spiral drying mechanism comprises a drying tube column 1, a hot air inlet 2 is provided at the lower end of the drying tube column 1, a spiral conveying pipe 3 is installed on the outer surface of the drying tube column 1 in a spirally wound manner, conveyor belt support seats 4 are installed on both sides of the inner cavity of the spiral conveying pipe 3, a spiral conveyor belt 5 is installed above the conveyor belt support seat 4, the surface of the spiral conveyor belt 5 is a mesh structure, a blowing frame 6 is provided below the conveyor belt support seat 4, a plurality of blowing holes 7 are evenly opened on the upper surface of the blowing frame 6, the blowing holes 7 correspond to the upper and lower surfaces of the spiral conveyor belt 5, an air inlet 8 is provided on the side of the blowing frame 6, the air inlet 8 passes through the side surface of the drying tube column 1 and is connected to the inner cavity of the drying tube column 1; a plurality of air outlet hoods 9 are evenly provided on the upper surface of the spiral conveying pipe 3, the air outlet hoods 9 are respectively connected to the exhaust pipe 10, and the discharge ends of the exhaust pipe 10 are all connected to the air outlet pipe 18.

[0024] In this embodiment, the upper end of the conveyor belt support base 4 is connected to the upper end of the conveyor belt loop support 11, and the lower end of the conveyor belt support base 4 is connected to one end of the feed frame 12. The other end of the feed frame 12 and the upper and lower ends of the conveyor belt loop support 11 are all equipped with a conveyor belt drive shaft. The spiral conveyor belt 5 passes through the upper surface of the conveyor belt support base 4, the conveyor belt drive shaft at the upper end of the conveyor belt loop support 11, the conveyor belt drive shaft at the lower end of the conveyor belt loop support 11, and the conveyor belt drive shaft at the end of the feed frame 12, and then is connected end to end to form a complete conveyor belt loop. One end of one of the conveyor belt drive shafts is connected to the drive end of the conveyor belt drive motor, which is installed on the outer side of the feed frame 12 or the outer side of the conveyor belt loop support 11 corresponding to the conveyor belt drive shaft.

[0025] Working principle:

[0026] Before use, the hot air inlet 2 at the lower end of the drying column 1 is connected to a hot air blower, and the hot air blower is used to deliver continuous hot air to the inner cavity of the drying column 1. The conveyor belt drive motor is started to drive the spiral conveyor belt 5 to run.

[0027] During use, the crushed kitchen waste can be uniformly and continuously fed from the position of the feed rack 16 to the upper surface of the spiral conveyor belt 5, so that the spiral conveyor belt 5 can drive the kitchen waste to move spirally upward along the inner cavity of the spiral conveying pipe 3; during the upward movement and transportation process, since the blowing frames 6 in the spiral conveying pipe 3 are connected to the inner cavity of the drying column 1, the hot air in the inner cavity of the drying column 1 can enter the blowing frames 6 from the air inlet 8 on the side of each blowing frame 6, and then blow air to the spiral conveyor belt 5 through the blowing holes 7 on the upper surface of each blowing frame 6. Since the surface of the spiral conveyor belt 5 is a mesh structure, the hot air can pass through the spiral conveyor belt 5, and then the kitchen waste on the upper surface of the spiral conveyor belt 5 can be dried by hot air. Moreover, along the route of the entire spiral conveying pipe 6, the kitchen waste can be continuously dried by hot air through the evenly distributed blowing frames 11, thereby effectively ensuring the drying effect of the kitchen waste. The dried kitchen waste is output from the upper end of the spiral conveyor belt 5, and the spiral conveyor belt 5 itself passes around the conveyor belt drive shaft at the upper end of the conveyor belt loop bracket 11, then moves downward along the conveyor belt loop bracket 11, and then passes around the conveyor belt drive shaft at the lower end of the conveyor belt loop bracket 11, moves to the end of the feed rack 12, and then returns to the initial position to form a complete conveyor belt loop.

[0028] Because the spiral conveying pipe 3 is wound around the outer surface of the drying column 1, the entire device occupies a very small area. Furthermore, the spiral conveyor belt 5 can achieve continuous conveying and drying of kitchen waste. Furthermore, the spiral structure of the spiral conveying pipe 3 significantly increases the length of the kitchen waste's travel path, thereby effectively ensuring the hot air drying effect on the kitchen waste.

[0029] In Example 2, as a further preferred embodiment of Example 1, a feed cover 13 is mounted above the feed frame 12, a feed pipe 14 is mounted above the feed cover 13, and a hollow discharge block 15 with an open lower end is mounted at the end of the feed pipe 14. A feed hole is defined at the front end of the upper surface of the feed cover 13, and the lower end of the discharge block 15 is mounted directly above the feed hole. In this embodiment, scraping teeth 16 are mounted at the rear end of the lower surface of the feed cover 13.

[0030] The kitchen waste conveying pipeline is connected through the feed pipe 14, so that the kitchen waste can be conveyed to the discharge block 15 through the feed pipe 14, and then fall to the upper surface of the spiral conveyor belt 5 through the opening at the lower end of the discharge block 15. Thereafter, during the process of conveying the kitchen waste through the spiral conveyor belt 5, the scraping teeth 16 can be used to evenly scrape the kitchen waste, thereby effectively ensuring the uniformity and continuity of the kitchen waste transportation.

[0031] In the third embodiment, as a further preferred embodiment of the first embodiment, a water collecting tank 17 is provided below the feed rack 12, and the water collecting tank 17 is directly opposite to the feed cover 13. The water collecting tank 17 can collect the sewage in the kitchen waste input through the feed pipe 34, thereby preventing the sewage in the kitchen waste from flowing out and polluting the environment.

[0032] In the fourth embodiment, as a further preferred embodiment of the first embodiment, the blowing frame 6 and the air outlet cover 9 are arranged in a staggered manner. By staggering the blowing frame 6 and the air outlet cover 9, the hot air blown out of the blowing frame 6 can fully stay in the spiral conveying pipe 3, thereby further ensuring the hot air drying effect on the kitchen waste.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
