Problems solved by technology

However, in the process of developing high-value transformation of straw, a large amount of soil impurities contained in straw have a huge impact on the comprehensive utilization of straw.
The papermaking and biomass power generation industries have made clear regulations on the soil trash content of straw, and soil trash will undoubtedly become the tailings of these industries, which will greatly increase the subsequent processing procedures and costs

Embodiment 1

[0063] The technology of the invention provides a complete set of equipment for high-efficiency impurity removal of corn stalks, including a gravity separation tank, a vibrating separation screen and a double-layer rolling separation screen. According to the principle of physical separation, firstly, the principle of gravity separation is used to separate the large pieces of soil and impurities contained in the straw in the gravity separation tank. Then, the soil and impurities adhered to the surface are further separated through the double-layer rolling separation screen. In the double-layer rolling separation screen, three rows of 15-30-degree wedge-shaped baffles (120-degree interval between each row) are set around the center line of the feed inlet. , evenly arranged along the axial direction, the inner drum screen is provided with evenly arranged sieve holes with a diameter of 30-50mm, the soil and impurities adhering to the surface of the straw are discharged from the sie...

Embodiment 2

[0065] The technology of the invention provides a complete set of equipment for high-efficiency impurity removal of corn stalks, including a gravity separation tank, a vibrating separation screen and a double-layer rolling separation screen. According to the principle of physical separation, firstly, the principle of gravity separation is used to separate the large pieces of soil and impurities contained in the straw in the gravity separation tank. Then, the soil and impurities adhered to the surface are further separated through the double-layer rolling separation screen. In the double-layer rolling separation screen, four rows of 15-30-degree wedge-shaped deflectors are arranged around the center line of the feed inlet (the interval between each row is 90 degrees). , evenly arranged along the axial direction, the inner drum screen is provided with evenly arranged sieve holes with a diameter of 30-50mm, the soil and impurities adhering to the surface of the straw are discharge...

Embodiment 3

[0067] The technology of the invention provides a complete set of equipment for high-efficiency impurity removal of corn stalks, including a gravity separation tank, a vibrating separation screen and a double-layer rolling separation screen. According to the principle of physical separation, firstly, the principle of gravity separation is used to separate the large pieces of soil and impurities contained in the straw in the gravity separation tank. Then, the soil and impurities adhered to the surface are further separated through the double-layer rolling separation screen. In the double-layer rolling separation screen, three rows of 15-30-degree fish-scale deflectors are arranged around the center line of the feeding port (the interval between each row is 120 degrees). ), evenly arranged along the axial direction, the inner drum screen is provided with evenly arranged sieve holes with a diameter of 30-50mm, the soil and impurities adhering to the surface of the straw are discha...

Abstract

The invention discloses a complete set of equipment for efficiently removing impurities from corn stalks and a method for removing impurities. The complete set of equipment includes a crusher, a gravity separation tank, a vibrating separation sieve, and a double-layer rolling separation sieve connected in sequence; the steps of the method for removing impurities It is: S1, put the whole straw into the crusher for crushing; S2, put the broken straw into the gravity separation tank for gravity separation, and separate the large pieces of soil contained in the straw; S3, pass through the gravity separation tank The separated straw is put into the vibrating separation screen for vibration separation, and the separated part is bonded to the soil impurities on the surface of the straw; S4. Put the straw separated by the vibrating separation screen into the double-layer rolling separation screen, and separate the straw by the inner cylinder rolling screen For the soil on the surface, the stalks blocked in the sieve hole of the inner cylinder are retrieved by the roller sieve of the outer cylinder.

Description

technical field [0001] The invention relates to the technical field of corn stover treatment, in particular to a complete set of equipment for high-efficiency impurity removal of corn stover and a method for removing impurities. Background technique [0002] Crop straw is a valuable renewable resource.
