Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of livestock and poultry manure resource utilization, specifically relating to a molded body made of compressed livestock and poultry manure. Background Technology
[0002] Livestock and poultry farming enterprises generate enormous quantities of manure, which is both pollution and a resource. Pollution control is urgent and difficult, while resource utilization has broad prospects. A key technology for transforming high-moisture livestock and poultry manure from pollution into a resource is dehydration and precipitation of the manure or sludge. The cost of dehydration and precipitation is crucial to ensuring the economic efficiency and sustainable operation of manure resource utilization projects. When the moisture content is reduced to below 65%, the manure is no longer in the easily polluted and deteriorated zone; when the moisture content is reduced to below 35%, it is ready for use in fertilizer production; and when the moisture content is reduced to below 20%, it is ready for use in biomass fuel combustion.
[0003] Existing technologies for the resource utilization of livestock and poultry manure organic fertilizer have issues with fertilizer production costs and fertilizer quality, while technologies for the resource utilization of livestock and poultry manure biomass fuel have problems such as difficulty in drying. As a result, existing high-moisture manure cannot be utilized as a resource, which is not conducive to the development of green animal husbandry.
[0004] Therefore, there is a need to provide a new molded structure for compressing livestock and poultry manure, which can achieve low manufacturing costs and good drying to maximize the utilization of livestock and poultry manure resources. Utility Model Content
[0005] To address the problems existing in the prior art, this utility model develops a molded structure for compressing livestock and poultry manure, effectively solving the drying and cost issues associated with high-moisture manure in large-scale pig farms.
[0006] To achieve the above objectives, this utility model provides a molded body made of compressed livestock and poultry manure, the molded body comprising 80%-100% livestock and poultry manure, the livestock and poultry manure having vertical through holes.
[0007] Furthermore, the animal manure product is a honeycomb-shaped compressed body.
[0008] Furthermore, the pressed body is a cylinder or a cuboid.
[0009] Furthermore, when the pressed body is a cylinder, the diameter of the cylinder is 8-20cm.
[0010] The advantage of this invention lies in the fact that the honeycomb-shaped cylindrical or square frame is formed by hydraulic machinery or other machines. The resulting honeycomb-shaped molded body has a porous structure with interconnected pores. High-moisture manure molded bodies are stacked and placed in a drying room for natural air drying. The porous honeycomb structure increases the evaporation area of the structure and accelerates the flow of evaporating water from the inside of the structure to the evaporation surface. Therefore, the molded body structure of livestock and poultry manure produced by this invention effectively solves the drying and cost issues associated with high-moisture manure in large-scale pig farms, effectively maximizing the utilization of livestock and poultry manure resources.

[0015] See Figure 1 , Figure 2 , Figure 3 This utility model provides a molded body made of compressed livestock and poultry manure, the molded body comprising 80%-100% livestock and poultry manure, the livestock and poultry manure having vertical through holes.
[0016] The livestock and poultry manure material described in this embodiment is a honeycomb-shaped compressed material.
[0017] The pressed body described in this embodiment is a cylinder or a cuboid.
[0018] In this embodiment, when the pressed body is a cylinder, the diameter of the cylinder is 8-20cm.
[0019] The preparation method of this embodiment is as follows: Mix the mixed fecal material with a moisture content of 60-65%, and press it into a honeycomb-shaped cylinder or a honeycomb-shaped square frame by hydraulic machinery or other machines; the pressed honeycomb-shaped molded body has a porous structure with interconnected upper and lower holes; the pressed honeycomb-shaped molded bodies are stacked and placed in a drying room to air dry naturally.
[0020] The fabrication of a porous honeycomb structure increases the evaporation surface area and accelerates the flow of evaporating water from the interior to the evaporation surface. For example, the total evaporation surface area of a honeycomb cylindrical structure (12cm in diameter, 6cm in height, with 12 straight holes of 1.4cm in diameter) is: S 总 =0.063749197m 2 Excluding the top and bottom areas, the evaporation area of the honeycomb-shaped molded body during stacking is: S 蒸发 =0.05428672m 2 Depending on weather conditions (temperature, humidity) and season, the highest evaporation rate of the high-humidity honeycomb-shaped structure was measured to be E when the temperature was high and the humidity was low in summer, and the difference between the dew point temperature and the air temperature was >7℃. 高 =
[0021] 0.037555886 kg / m 2 • h, the material needs to be dried for 7 days to reach 20% dryness; during the spring rainy season, when humidity is high and the difference between the dew point temperature and the air temperature is <2℃, the minimum evaporation rate E under the most unfavorable conditions. 低 =
[0022] 0.009333280kg / m 2 •h, the material needs to be dried for 21 days to reach 35% moisture content. When the dew point temperature is artificially adjusted to be more than 5°C different from the air temperature, the dehydration speed of the material can be accelerated, and the moisture content can eventually reach around 20%.
[0023] This utility model provides a molded body for compressing livestock and poultry manure, which is easy to dry and suitable for dehydration treatment of high-moisture manure in large-scale pig farms. It features simple operation, safety, no energy consumption, and low cost. The development of this molded body structure effectively solves the problems of environmental pollution and high cost of manure resource utilization in large-scale farms.
[0024] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
