Description

TECHNICAL FIELD

[0001] The utility model relates to a drum type composting reaction equipment, concretely relates to a fermentation device for preparing carbon-based organic fertilizer by using wine brewing waste. BACKGROUND

[0002] China is a big country of liquor production and consumption, and the annual output of liquor is 13 million tons, of which Luzhou-flavor liquor accounts for 75% of the total output of liquor. About 3 tons of distiller's grains and 6-7 tons of wastewater are produced per ton of liquor. The moisture content of distiller's grains is about 80%, the rice hull content is more than 60% (dry basis), the pH is 4.0-4.5, and the main components are cellulose, silicon dioxide and a small amount of protein, which have low nutritional value and poor palatability, and are not suitable for feed. At present, incineration is the main way of harmless treatment of distiller's grains, which has high energy consumption, high cost and low resource utilization rate. However, it is worth noting that distiller's grains are rich in organic matter and plant nutrients, and are a potential source of organic fertilizer. The production of carbon-based organic fertilizer from distiller's grains can make full use of organic matter and nutrient resources, and fully combine harmless treatment with resource utilization. However, the pH of distiller's grains alone is low, and it is difficult to compost. The production of biochar from part of the distiller's grains and the fermentation of organic fertilizer together can neutralize the pH due to the alkalinity of biochar, increase the activity of microorganisms in the fermentation process, promote the efficient composting of distiller's grains organic fertilizer, and form carbon-based organic fertilizer, which can increase soil organic carbon storage, improve soil microbial activity, and promote crop growth, which is better than ordinary organic fertilizer. However, there are still few devices for producing distiller's grains carbon-based organic fertilizer, and the effect is not clear. The commonly used fermentation equipment at present is a drum type composting reactor, which mainly relies on the internal scoop of the drum to lift the material to form a curtain, which can mix the material and promote composting fermentation. In actual operation, the internal scoop of the drum will stick to the material, and as the material continues to accumulate, the original structural parameters of the scoop will be changed, resulting in reduced working efficiency. In addition, due to the high viscosity and low flowability of distiller's grains containing starch and other substances, the material cannot be fully mixed during fermentation, which seriously affects the degradation rate of fermentation.

[0003] Therefore, it is necessary to solve the technical problems of uneven mixing of materials during fermentation, poor fermentation effect and low working efficiency in the production of distiller's grains carbon-based organic fertilizer. UTILITY MODEL CONTENT

[0020] The fermentation device for preparing carbon-based organic fertilizer from distiller's grains in the embodiment comprises a horizontal fermentation drum 1 and a driving mechanism for driving the rotation of the drum 1, a plurality of scoop plates 2 are arranged along the inner wall of the drum 1 in a circumferential direction at intervals, the scoop plate 2 is an arc-shaped plate, the scoop plate 2 is arranged on the drum wall in a perpendicular manner to the axis of the drum, and the end of the scoop plate 2 is gradually inclined and curved in the direction of rotation of the drum 1, and the cross section of the fixed end of the scoop plate 2 to the drum wall is larger than that of the end. The fermentation drum 1 is horizontally placed, not vertically placed. The driving mechanism comprises a motor and a rotating shaft, etc., and the installation and setting of the driving mechanism and the driving principle are all prior art, which will not be described here. Of course, the fermentation drum 1 is the main place for composting experiments and the main structure of the experimental equipment, and is also provided with an inlet and outlet, an air outlet, an aeration device, a temperature sensor, etc., all of which are conventional designs. The scoop plate 2 is an arc-shaped plate, and is a variable cross-section arc-shaped plate. From the side of the drum, the scoop plate 2 is approximately triangular in shape with a large bottom and a small top, and the end of the plate is gradually inclined and curved to form an arc surface, and the direction of the inclined and curved end of the scoop plate 2 is consistent with the direction of rotation of the drum 1, which is conducive to the scoop plate 2 to scoop up the material while rotating with the drum, has a large scooping angle, can form a good material curtain, can fully mix the material during lifting, and can also increase the contact between the material and oxygen to strengthen the effect of aerobic fermentation.

[0021] In the embodiment, the inclination angle of the end of the scoop plate 2 is 30-40°, which can better form a material curtain and improve the uniformity of mixing.

[0022] In the embodiment, the scoop plate 2 is arranged in two circles along the axial direction of the drum, and the height of the scoop plate 2 is 1 / 10 of the inner diameter of the drum. The height of the scoop plate 2 is set to ensure the strength and service life of the scoop plate 2, and also to ensure the scooping effect of the scoop plate 2.

[0023] During the rotation of the drum 1, the scoop plate 2 can play a good stirring role, which can not only avoid the formation of stirring dead angles in the drum 1, but also prevent the accumulation of material at one end of the drum 1.

[0024] In the embodiment, the cross section of the scoop plate 2 gradually decreases from the fixed end to the end. In order to improve the strength of the scoop plate 2 and prolong the service life of the scoop plate 2, the thickness of the fixed end of the scoop plate 2 is increased, which is equivalent to a base, and the thickness gradually decreases from the fixed end to the end of the scoop plate 2 in the height direction. In order to ensure the strength of the scoop plate 2, the end can maintain a certain distance with the same thickness. That is, the scooping section of the scoop plate 2 can be a plate with the same thickness, and the scooping section to the fixed section is a variable cross-section.

[0025] In the embodiment, the blade 2 has a hollow structure; the temperature of the blade 2 has a significant influence on the adhesion amount of the material liquid and the material on the blade 2, and the thin sheet type blade 2 is greatly affected by the temperature, and the temperature rises quickly and falls quickly. The heat transfer mode of the solid is mainly heat conduction, and the heat transfer mode of the fluid such as air is mainly heat convection, and the heat transfer speed of the heat conduction is obviously slower than that of the heat convection, so the hollow structure can reduce the heat dissipation rate, thereby playing a heat preservation role. The hollow blade 2 design has heat insulation and heat preservation functions, and under the action of hot air and steam in the cylinder, the temperature of the cylinder and the blade 2 rises quickly, and at the same time, the cylinder temperature can be continuously transmitted to the blade 2, preventing the blade 2 from being accumulated with material liquid and condensed water due to temperature drop, thereby effectively reducing the adhesion of the material on the blade 2.

[0026] In the embodiment, a hollow structure is arranged at the part of the blade 2 close to the mounting portion; the cross section (thickness) of the mounting portion is large, which can not only meet the design of the hollow structure, but also ensure the strength. The hollow part can be arranged in communication along the length direction of the blade 2 (parallel to the axis direction of the cylinder), or arranged at intervals.

[0027] In the embodiment, the blade 2 is made of stainless steel, the inner side surface 201 of the blade 2 in the inclined direction is a smooth surface with a Teflon coating, and the outer side surface 202 in the inclined direction is provided with a rib 203, which is distributed at equal intervals along the height direction of the blade 2; the "inner side surface" refers to the surface in the bending direction, which is equivalent to one side of the concave arc, and this surface has a Teflon coating and is smooth, and has the best anti-adhesion effect. The surface opposite to the bending direction is the outer side surface, which is equivalent to one side of the convex arc, and this surface is provided with the rib 203 extending and distributed along the height direction of the blade 2, which can crush the granules formed during the mixing process, improve the mixing uniformity, and avoid affecting the quality of the later composting. At the same time, the rib 203 also plays a role of reinforcing rib of the blade 2, prolonging the service life of the blade 2. Sharp teeth can also be arranged at the end of the blade 2, which is also convenient for crushing the granules formed during the mixing process, and also promotes the dispersion of the material.

[0028] In the embodiment, the rib 203 is a thin sheet structure; the crushing effect is better, and it is beneficial to be fixed on the blade 2.

[0029] In the embodiment, a heat preservation layer is arranged on the outer surface of the horizontal fermentation drum 1 cylinder; the thickness of the heat preservation layer is 15-25 mm, and the heat preservation layer is made of polyurethane material. The heat preservation effect is beneficial to improve the fermentation effect, and the thickness of the heat preservation layer should not be too large, otherwise it will affect the weight of the drum 1, and too small will affect the heat preservation effect, so the most suitable thickness of the heat preservation layer is 15-25 mm.

[0030] Finally, it is explained that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the purpose and scope of the present application. The technical solutions of the present application should be covered in the scope of the claims of the present application.
