Description

Equipment for drying chicken manure by hot air and chicken manure treatment system thereof Technical Field The invention relates to the technical field of livestock raising manure treatment, in particular to equipment for drying chicken manure by hot air and a chicken manure treatment system thereof. Background In the agricultural waste treatment field, the equipment for drying chicken manure by hot air rapidly removes water through high-temperature air flow, combines intelligent control and environmental protection design, solves the problems of low treatment efficiency and large pollution of the traditional chicken manure, and realizes the recycling, harmless and high-value utilization of wastes. The technology is mature and simple and convenient to operate, so that the technology becomes one of core equipment of a large-scale farm and an organic fertilizer processing enterprise, and is developed based on the requirements of efficient dehydration, sterilization and resource recycling of wet chicken manure and by combining thermodynamic, heat and mass transfer principles and mechanical engineering. The equipment for drying chicken manure by hot air is used for solving the limitations of the traditional airing, such as low natural airing efficiency, long time consumption, easiness in weather influence, incapability of killing pathogenic bacteria and eggs, and difficulty in meeting the requirement of large-scale cultivation. The initial water content of the fresh chicken manure is generally 75-80%, and is reduced to 15-20% for safe storage and transportation so as to prevent mildew and reduce weight. For organic fertilizer production, energy utilization, direct field returning and the like, the water content of 10% -15% is usually required to facilitate granulation and preservation. Chinese patent document CN221139758U discloses a dirty excrement board guiding mechanism of using of excrement, including the mounting panel that two intervals set up, its characterized in that, two the guide component is installed to mounting panel one side in opposite directions, the guide component includes along vertical setting and is fixed in the fixed part on the mounting panel, and it has the mobile part of slope setting to slide along the horizontal direction on the mounting panel that is located the fixed part below, elastic connection and mobile part, fixed part cooperate between mobile part, the mounting panel and realize the removal orbit of adjustment excrement board. The prior art can air-dry the upper layer chicken manure and the lower layer chicken manure on one drying line at the same time. Chinese patent document CN206905488U discloses a chicken manure hot air drying equipment, including sealing connection at the wind collecting chamber of chicken coop afterbody, the chicken coop afterbody is equipped with a plurality of first row wind windows that link to the wind collecting chamber, be equipped with the stoving box in the wind collecting chamber, the one end of stoving box stretches out to the wind collecting chamber outside, the part that the wind collecting chamber was arranged in to the stoving box is opened, vertical interval is equipped with the multilayer conveyer belt on the stoving box, and staggered arrangement makes lower floor's conveyer belt can follow the excrement and urine that upper conveyer belt falls down between the multilayer conveyer belt, be equipped with the air exhauster on the end that the wind collecting chamber was arranged in to the stoving box, be equipped with chicken manure spreading device on the transport head end of first floor's conveyer belt, the conveyer belt of last one deck has the conveyer device that exports chicken manure below the transport end. At present, in order to air-dry a large amount of chicken manure simultaneously and promote output, a plurality of groups of manure board guiding mechanisms are required to be arranged in the equipment for drying the chicken manure by hot air, and in the prior art, the drying box of the equipment for drying the chicken manure by hot air is poor in drying effect of a multi-layer conveying belt, because heat is easy to directly drain away along with wind in the drying equipment, and the chicken manure close to a hot air outlet is easy to dry, and the chicken manure far away from an air drying port is not easy to dry, so that the drying uniformity is poor, and the repeated air drying or the air drying temperature of the drying box is required to be increased, and the cost is further increased. Disclosure of Invention In order to solve the technical problem, the invention provides equipment for drying chicken manure by hot air, which can simultaneously dry multi-layer chicken manure, and comprises a drying box and a heating box, wherein a multi-layer conveying mechanism is arranged in the drying box. Preferably, the hot air outlets of the heating box and the air return box correspond to different levels of transportation mechanis
