Abstract

The invention discloses a device for filtering biogas slurry by using corn stalks and a process for concentrating and separating biogas slurry. The lower end of the device is fixedly connected with a transmission shaft, the transmission shaft is driven to rotate by a motor, the lower end of the transmission shaft is covered with a bearing, the shaft wall of the transmission shaft is fixedly connected with a pair of upper support arms and lower support arms, and a pair of upper support arms A filter cartridge is fixedly connected with the end of the lower support arm away from the transmission shaft, the lower end of the filter cartridge is hinged with a screen through the connecting shaft, and a fixing plate is arranged below the filter cartridge. The device can use corn stalk filter material to filter the biogas slurry, so that the suspended solids in the biogas slurry can be effectively removed, and the filtered filter material is composted, and the filtered biogas slurry is recycled after treatment, which reduces the cost of biogas slurry treatment and has a good effect. economic benefits.

Description

technical field [0001] The invention relates to the field of resource recycling of agricultural organic waste, in particular to a device for filtering biogas slurry by using corn stalks and a biogas slurry concentration and separation process. Background technique [0002] Biogas slurry is rich in nutrients such as nitrogen, phosphorus and potassium, and most of them are available nutrients. In addition, it is also rich in amino acids, B vitamins, various hydrolytic enzymes, certain plant hormones, substances or factors that can inhibit pests and diseases, and a large amount of micronutrients such as calcium, copper, iron, zinc and manganese. Therefore, biogas slurry has favorable factors as a high-quality organic fertilizer. [0003] The existing methods of using biogas slurry as fertilizer mainly include drip irrigation direct application and film concentration and then dilution application. Both of the above two application methods have a common technical obstacle, that...
