Organic fertilizer screening device with fertility recycling function

Abstract

The invention provides an organic fertilizer screening device with a fertility recycling function. The organic fertilizer screening device comprises a first barrel, a second barrel and a third barrel, a hopper is installed on one side of the first barrel, a cyclone barrel is installed on the other side of the third barrel, a guide pipe is welded to the bottom of the hopper, an air barrel is welded to one side of the first barrel,one side of the first barrel is provided with a motor through a bolt, the other sides of the first barrel, the second barrel and the third barrel are welded with sleeves, and the outer side of the sleeves is sleeved with a clamping sleeve. According to the organic fertilizer screening device with the fertility recycling function, soil particles and sand can be separated out of organic fertilizer step by step, the situation that the soil particles and the sand are not thoroughly separated is avoided, effective fertility in soil grains, sand and stones is extracted, fertility waste is prevented, the filter screen is used for filtering when not needed, the air speed of airflow is effectively guaranteed, fertility in water is absorbed through organic fertilizer, the fertility in water does not need to be extracted, the production cost is reduced, and the device is suitable for screening of the organic fertilizer.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer screening equipment, in particular to an organic fertilizer screening device capable of recovering fertility. Background technique [0002] During the production and processing of organic fertilizers, in order to ensure the quality of organic fertilizers, organic fertilizers need to be screened.

[0002] During the production and processing of organic fertilizers, in order to ensure the quality of organic fertilizers, organic fertilizers need to be screened. The patent application number is CN201910221974.5, which discloses an organic fertilizer screening machine. The existing organic fertilizer screening equipment is basically It has the advantages of fast screening speed, large screening capacity, high working stability, no organic fertilizer clogged screen, long service life, etc., and can meet the needs of organic fertilizer screening operations. However, for the existing organic fertilizer As far as fertilizer screening equipment is concerned, on the one hand, in the process of screening, it is often only possible to classify the size of organic fertilizer particles, and cannot effectively remove soil particles and sandstones contained in organic fertilizers. Transportation and processing costs reduce the quality of organic fertilizer. On the other hand, after the soil particles and sand are separated from the organic fertilizer, the soil particles and sand are mixed with the organic fertilizer for a long time, making the soil and sand The stone absorbs part of the fertility of the organic fertilizer, resulting in the loss of the fertility of the organic fertilizer. On the other hand, in the process of screening, it is easy to generate a certain amount of dust. The traditional filter equipment is easy to reduce the wind speed, which is not conducive to the use of gravity. It is separated from soil particles and sand, which is not conducive to the collection of organic fertilizer dust under the condition of ensuring wind speed
