Description

Black soldier fly larva and worm sand separating device

Technical Field

The utility model belongs to the technical field of the heisui river horsefly facility of breeding, concretely relates to heisui river horsefly larva and separator of worm's sand.

Background

Black soldier fly (Hermetia illucensL.) is known as Hermetia illucens, a saprophytic Hermetia of the order Diptera; the black soldier flies are native to America, are widely distributed all over the world (between 40 degrees in south and north), are introduced into China in recent years, and are mainly cultured in tropical and warm temperate regions of China. The black soldier fly feeding behavior only occurs in a larva stage, the white fat larva body has higher nutritional value, and the black soldier fly larva can be quickly decomposed and converted into organic wastes such as livestock and poultry manure and the like to generate organic fertilizer and larva body protein, so that high-value animal protein or aquatic feed is produced, and the black soldier fly feeding behavior is widely applied to the aspect of treating wastes such as chicken manure, pig manure, kitchen waste and the like at present; the black soldier fly larvae can digest and generate a large amount of organic matter insect sand in the feeding and growing process, and the insect sand is a high-quality natural organic fertilizer and has quite high economic value.

At present, the existing black soldier fly larva breeding and cultivating technology is relatively mature, but in the black soldier fly breeding process, how to effectively separate the black soldier fly larvae from the generated worm sand is the next relatively complex problem, and the problem is also a big difficulty in limiting and reducing the breeding cost of the black soldier fly. Currently, a common method for screening a mixture of the black soldier fly larvae and the sand is to separate the black soldier fly larvae and the sand by means of air separation, a drum screen and a multi-layer vibrating screen. The separation mode of air separation mainly utilizes the different suspension speeds of larvae and the worm sand in the mixture so as to remove the worm sand, impurities and dust; however, the method has very strict requirements on the water content of the mixture, when the water content of the mixture is higher, the densities of the black soldier fly larvae and the sand are close, the masses of the black soldier fly larvae and the sand are close, and the suspension speeds of the black soldier fly larvae and the sand are close, so that the effective separation of the black soldier fly larvae and the sand is difficult to realize in a sorting mode. The separation mode of the drum screen is that a mixture entering the drum is overturned and rolled through a drum device obliquely arranged on the rack, so that qualified materials, namely black soldier fly larvae, are discharged through a discharge hole in the bottom of the rear end of the drum, and unqualified materials, namely worm sand, are discharged through a discharge hole in the tail part of the drum.

The existing separation mode is a mode of separating larvae by vibration of a multilayer vibrating screen, a motor is used as a vibration source, so that the mixture of the black soldier fly larvae and the sand is thrown up on a screen mesh and moves forwards in a straight line, the black soldier fly larvae are bunched together through a plurality of layers of screens, and the black soldier fly larvae and the worm sand are separated by combining manual separation, the method has single principle, complex working procedures and huge space requirements due to large consumption of manpower, and the mixture of the black soldier fly larvae and the sand is complex in components and difficult in uniform particle size after the breeding is finished, particularly the volume of the black soldier fly larvae is different, in the practical application process, the separation quality is poor, and due to different production requirements in the black soldier fly breeding process, the water content of the mixture changes greatly, and too high a moisture content of the mixture may cause the fine and soft insect sand in the mixture to stick to the screen. Therefore, how to improve the screening efficiency and the separation quality of the hermetia illucens larvae and the worm sand has important practical application value and higher economic value for the rapid and sustainable development of the existing hermetia illucens larva breeding industry.

The applicant has therefore made an advantageous design, in the context of which the solution to be described below is made.
