1. Principle and advantages of screw press
Screw press is a device that uses mechanical pressure to squeeze out water from livestock and poultry manure. Its working principle is to gradually push the manure to the pressing area through the rotation of the screw shaft, while applying increasing pressure to separate the water from the manure. This equipment has the following significant advantages:
Screw Press Livestock Sludge Dewatering Machine QXDL-402
(I) Efficient dehydration
The screw press can reduce the moisture content of livestock and poultry manure to 60% - 70% or even lower in a short time, greatly reducing the volume and weight of the manure and reducing the cost of subsequent treatment.
(II) Easy to operate
The equipment has a compact structure and simple operation. Just feed the manure into the feed port to automatically complete the dehydration process without manual intervention, saving a lot of manpower and time.
(III) Environmentally friendly and pollution-free
During the dehydration process, the water in the manure is effectively separated, reducing the generation of odorous gases, while avoiding the pollution caused by direct discharge of manure to the environment, meeting environmental protection requirements.
(IV) Resource recovery
The dehydrated feces has low water content and a relatively dry texture. It can be directly recycled as a raw material for organic fertilizer, realizing the recycling of resources and creating additional economic value for the enterprise.
2. Application cases of screw press
(I) Large pig farm
A large pig farm produces several tons of feces per day. In the past, it used traditional composting methods, which not only occupied a large area, but also had a foul smell and caused constant complaints from surrounding residents. Since the introduction of the screw press, the feces have been dehydrated, the volume has been greatly reduced, and the odor problem has been effectively solved. At the same time, the dehydrated feces are made into organic fertilizer, which brings hundreds of thousands of yuan of additional income to the company every year.
(II) Cattle farm
The feces in cattle farms have a high water content and are difficult to handle. The emergence of screw presses has brought new hope for the treatment of feces in cattle farms. Through dehydration treatment, the manure from the cattle farm is not only rendered harmless, but also provides high-quality organic fertilizer for the surrounding farmland, improves soil quality, promotes the growth of crops, and achieves a virtuous interaction between animal husbandry and agriculture.
