Description
Technical Field
The disclosure relates to the technical field of environmental protection, in particular to a system for sorting hermetia illucens larvae in a mixture and a using method thereof.
Background
The black soldier fly is a dipteran soldier fly which originates in the America, and can efficiently treat organic waste due to the characteristics of rapid propagation, large biomass, wide feeding habits, high absorption and conversion rate, easy management, low feeding cost, good animal palatability and the like. The larval white fat bodies formed by the black soldier flies after the organic waste is treated have high nutritive value, and are widely applied to the treatment of wastes such as chicken manure, pig manure, kitchen waste and the like at present.
The separation process of the mixture formed after the black soldier fly is treated with the organic solid waste is an important problem in the current black soldier fly processing process. The mixture formed after the organic solid waste is treated comprises the following components: black soldier fly larvae; black soldier fly dung; light substances such as the dermatophytes, the pepper skin and the fibers. Currently, the separation of the hermetia illucens larvae from other substances is realized by means of air separation, a parallel vibrating screen, a drum screen and the like.
The air separation is a method for removing impurities by wind power by utilizing the difference of the suspension speed between materials and impurities. The aim of air separation is to remove impurities and dust and also to remove heavier impurities, and air separation is suitable for separating solid wastes with similar particle shapes and sizes. The air separation is used for separating the black soldier flies, and the mixture is formed after the organic solid waste is treated, wherein the suspension speed of different components in the mixture is mainly utilized. However, the method has high requirements on the water content of the mixture, and when the water content is higher, the weight of the insect manure and the weight of the black soldier fly larvae are close, so that the separation is difficult to realize.
The parallel vibrating screen utilizes a motor as a vibration source to enable materials to be thrown up on the screen and to move forwards in a straight line, the materials uniformly enter an inlet and an outlet of the screening machine from the feeding machine, and oversize products and undersize products of tree species specifications are generated through the multiple layers of screen meshes and are respectively discharged from respective discharge ports. The method utilizes the differences of the weight, shape, volume and the like of the hermetia illucens larvae and the hermetia illucens larvae in the mixture to realize the separation of the hermetia illucens larvae and the insect feces in the mixture, but the method has a single principle and has a poor separation effect in the practical application process. The water content of the mixture, the uniformity of the size of the worms and other factors all influence the separation effect. Too high a water content of the mixture results in the attachment of the fine-textured faeces to the screen and the poor separation due to uneven size of the worms.
The drum screen is characterized in that the drum device is obliquely arranged on the frame. The motor is connected with the roller device through the speed reducer by the coupler, and the roller device rotates around the axis of the roller device. After the materials enter the roller device, the materials on the screen surface are overturned and rolled due to the inclination and rotation of the roller device, so that the qualified materials (undersize products) are discharged through a discharge hole at the bottom of the rear end of the roller, and the unqualified materials (oversize products) are discharged through a discharge hole at the tail part of the roller. The principle of the method is almost the same as that of a parallel vibrating screen, and the separation effect in the practical application process is poor. And is also affected by the water content of the mixture, the uniformity of the size of the worms and other factors.
Therefore, it is necessary to provide a sorting system having a good separation effect and less affected by the uniformity of the water content and the size of the worms.
