Description

Technical Field

[0001] This utility model relates to the field of animal husbandry technology, and in particular to a production line for cattle bedding materials. Background Technology

[0002] In dairy farming, increasing milk production is a key objective, and improving the living environment of dairy cows, especially providing comfortable, clean, and dry bedding, is crucial for enhancing their rest quality, health, and milk yield. Cow manure, as bedding material, is an ideal material due to its hygiene, safety, comfort, and ease of waste management. However, the current common process involves separating the solid and liquid components of cow manure and then piling it for fermentation, a process that takes at least 12 days. This long fermentation time and production cycle make it difficult to meet the rapid replacement needs of dairy farms for bedding material, thus limiting the improvement of production efficiency and economic benefits. Optimization and improvement are urgently needed. Utility Model Content

[0003] The purpose of this utility model is to provide a production line for cow bedding materials, which is made from cow manure and has a shorter production cycle, thus improving production efficiency.

[0004] The technical solution to achieve the purpose of this utility model is: a cattle bedding material production line, comprising a filter press, a fermentation tank, and a dryer arranged sequentially along the production line direction; several aeration pipes are laid parallel to each other on the inner bottom of the fermentation tank, with the distance between two adjacent aeration pipes being 0.8 to 1.2 meters; each aeration pipe has several aeration holes along its length, with the distance between two adjacent aeration holes on the same aeration pipe being 0.8 to 1.2 meters; the aeration pipes are connected to an air compressor, which provides compressed air; the fermentation tank contains solid cattle manure obtained after filter pressing, and the top of the solid cattle manure is covered with a composting film; the dryer is a rotary dryer.

[0005] This invention improves the oxygen concentration in the fermentation tank by installing aeration pipes at the bottom inside the fermentation tank, limiting the distance between the aeration pipes and aeration holes, and setting up a compost membrane. At the same time, it ensures the uniformity of oxygen and temperature in the fermentation tank, thereby effectively accelerating the fermentation process. Furthermore, by using a rotary dryer for drying, the entire production cycle of cow bedding material is shortened to 7 days, which is beneficial to improving the production efficiency and economic benefits of dairy farms.

[0006] Furthermore, the diameter of the aeration holes is preferably 2 to 4 cm to avoid generating bubbles that are too large or too small, which would affect the oxygen transfer efficiency.

[0007] Furthermore, the fermentation tank is equipped with a material storage area and a material fermentation area; the filter press is correspondingly located in the material storage area of ​​the fermentation tank; and the material fermentation area of ​​the fermentation tank is correspondingly located in the dryer. During operation, the solid cow dung obtained from the filter press can be temporarily stored in the material storage area. After the material in the material fermentation area completes fermentation and is transferred away, the material in the material storage area is then transferred to the material fermentation area for further fermentation. While waiting for the material to ferment in the material fermentation area, the filter press can perform normal unloading operations. Furthermore, the material in the material storage area also naturally accumulates and ferments during the waiting process, reducing filter press downtime, achieving continuous operation, and further improving production efficiency.

[0010] The preferred embodiment of the cow mattress production line of this utility model is described in detail below with reference to the accompanying drawings.

[0011] Combination Figure 1 and Figure 2 A cattle bedding production line includes a filter press 10, a fermentation tank 20, and a dryer 30 arranged sequentially along the production line direction. Several aeration pipes 40 are laid parallel to each other on the inner bottom of the fermentation tank 20, with a distance of 0.8 to 1.2 meters between adjacent aeration pipes 40. Each aeration pipe 40 has several aeration holes 41 along its length, with a distance of 0.8 to 1.2 meters between adjacent aeration holes 41 on the same aeration pipe 40. The aeration pipes 40 are connected to an air compressor 50, which provides compressed air. Solid cow manure 60 obtained after filter pressing is accumulated in the fermentation tank 20, and a composting film 70 is placed over the pointed top of the solid cow manure 60. The dryer 30 is a rotary dryer.

[0012] During operation, the cow manure to be processed is first separated into solid and liquid components by a filter press 10 to obtain solid cow manure 60 with low moisture content. The solid cow manure 60 is then piled in a fermentation tank 20, and a composting film 70 is placed on the top of the solid cow manure 60 for fermentation. The composting film 70 can reduce heat loss and maintain a high-temperature environment (70-80°C) inside the compost, thereby accelerating the decomposition and fermentation process of organic matter. Furthermore, an intermittent aeration mode is adopted during the fermentation process, and aeration is carried out through an air compressor 50 and an aeration pipe 40. The specific aeration cycle is: aeration for 20 minutes, followed by a 10-minute aeration stop. This mode is repeated throughout the fermentation process to ensure the uniform distribution and effective utilization of oxygen in the fermentation tank 20. Finally, the fermentation product is sent to a dryer 30 for drying to obtain cow bedding material.

[0013] Using the cattle mattress production line of this invention, the entire production cycle of cattle mattress material can be shortened to 7 days.

[0014] Furthermore, the diameter of the aeration hole 41 is preferably 2-4 cm. The smaller the diameter of the aeration hole 41, the smaller the bubbles produced, and vice versa. Controlling the diameter of the aeration hole 41 to 2-4 cm avoids producing bubbles that are too large or too small, which would affect the oxygen transfer efficiency.

[0015] Furthermore, the fermentation tank 20 is provided with a material storage area 21 and a material fermentation area 22; the filter press 10 is correspondingly arranged with the material storage area 21 of the fermentation tank 20; the material fermentation area 22 of the fermentation tank 20 is correspondingly arranged with the dryer 30. During operation, the solid cow dung 60 obtained by pressing can be temporarily stored in the material storage area 21. After the material in the material fermentation area 22 has completed fermentation and been transferred away, the material in the material storage area 21 is then transferred to the material fermentation area 22 for fermentation. While waiting for the material in the material fermentation area 22 to ferment, the filter press 10 can perform normal unloading operations. Furthermore, the material in the material storage area 21 is also accumulating and fermenting during the waiting process, reducing the downtime of the filter press, achieving continuous operation, and further improving production efficiency. Of course, the fermentation tank 20 can also only have a material fermentation area 22. In this case, the filter press 10 is in a stopped state throughout the entire fermentation process, resulting in a longer waiting time.

[0016] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent process transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
