Description

Technical Field

[0001] The invention belongs to the field of drying and storage of agricultural products, and in particular relates to an integrated drying and storage bin and an operating method. Background Art

[0002] Agricultural products such as grain and oilseeds have a high moisture content when harvested and need to be dried in time to avoid mold and deterioration. According to statistics, the mechanization rate of post-harvest preservation of grain in my country, such as drying and storage, is only 38%, and the mechanization rate of post-harvest preservation of oilseeds is about 26.7%, which cannot meet the demand for mechanized drying and storage of grain and oilseeds. At present, the comprehensive post-harvest loss rates of grain and oilseeds in my country are 15.28% and 14.97% respectively. Among them, the loss rates of drying and storage of farmers' grain storage are 5.2% and 10.09%, 6.21% and 20.04% respectively. The loss rate in the whole link from post-harvest harvest to sales is the highest, which affects the effective supply of grain and oil and the increase of farmers' income. In recent years, mechanized drying has been vigorously developed, but it still faces the problems of difficult approval of construction land, high investment cost, high operating cost and low profit margin. Mechanical ventilation is a globally recognized green drying and storage technology that can reduce drying energy consumption, integrate drying and storage functions, reduce construction land area, improve equipment utilization, and maintain appropriate moisture content to meet subsequent processing needs. In addition, business entities can temporarily store grain and oil and sell them at the right time to improve the comprehensive benefits of grain production.

The drying device includes a cylindrical drying bin, a ventilation pipe, an air distribution column, a fan, a belt conveyor and a support frame. The cylindrical drying bin equipment has a conical upper cover and an inverted conical lower cover. This invention can realize electric heating grain drying and avoid the problem of environmental pollution caused by traditional coal-fired drying. However, there are problems such as complex ventilation pipe structure, easy discharge stagnation in the existing structure, and lack of effective insulation measures for the bin body. The prior art discloses a grain production site dry storage integrated warehouse and operation method, and its application number is: 202311293005. Its structure includes a cylindrical silo, a ventilation system and a material distribution system, which greatly improves the uniformity of grain ventilation and drying, but the ventilation cage horizontal pipe has certain obstacles to the circulation of grain, which is easy to accumulate, and its fan needs to be suspended, which is inconvenient to install and repair.

[0068] Embodiment three:

[0069] like Figure 7 As shown, the present invention also provides an operation method of an integrated dry storage bin, comprising the following steps:

[0070] Step 1, removing impurities from the raw materials through the dust removal fan 4 and the dust collecting pipe 5 of the conveying system;

[0071] Step 2, the impurity-removed material is sent into the silo body through the upper chute 3 of the conveying system;

[0072] Step 3, testing and judging the moisture content of the material sent into the silo body;

[0073] If the moisture content of the material fed into the silo body is less than or equal to the target moisture content, it enters the storage mode. If the moisture content is greater than the target moisture content, it enters the drying mode for ventilation, precipitation and grain circulation.

[0074] The ventilation and precipitation process in step 3 includes mechanical ventilation and natural ventilation, with mechanical ventilation being the main method. Mechanical ventilation can achieve alternating use of forced air and induced air through a reversing ventilation system, promoting uniform distribution of temperature or moisture in the inner and outer layers of the material.

[0075] The grain circulation in step 3 includes two types: whole-bin circulation and part circulation. The whole-bin circulation is achieved by opening the four cone valves as a whole, and the part circulation is achieved by regulating the opening of different cone valves. The form of part circulation is divided into a single cone circulation in sequence and a combination of opposite cones in sequence. Used in conjunction with the ventilation process, it ensures that the material temperature, moisture and other states are evenly distributed.

[0076] Step 4: When the moisture content of the material in the silo body is less than or equal to the target moisture content, stop ventilation and enter storage mode;

[0077] Step 5: When the temperature of the material in storage mode rises due to environmental conditions, ventilation or grain circulation is performed to cool the material under the condition that the external environment temperature is lower than the material temperature. When the material temperature drops to a certain temperature, ventilation or material circulation is stopped.

[0078] Compared with the prior art, the beneficial effects of the present invention include at least:

[0079] (1) The present application sets up a cone discharging system, which solves the problem of uneven discharging of the inner and outer layers of the bin and stagnation of discharging when the existing equipment circulates grain in and out;

[0080] (2) The ground ventilation system and ventilation pipe combination provided in the present application can not only realize ventilation, but also play the role of supporting and fixing the ventilation cage, avoiding the grain blocking effect caused by the support rods and transverse ventilation pipes provided in the warehouse. The structure is simple and easy to install, which improves the uniformity of ventilation and reduces the energy consumption of drying.

[0081] (3) This application is equipped with a material discharge circulation and material position circulation process in the bin. On the basis of realizing the self-circulation of the material discharge of the entire bin, the circulation of materials at different positions in the bin is realized by controlling the opening and closing of the cone valve, thereby further improving the uniformity of material circulation and ventilation effects;

[0082] (4) The present application sets inner and outer warehouse walls, and sets shutters on the outer warehouse wall, which can be used as the inlet and outlet of air during mechanical ventilation, and can also be used as the inlet and outlet of natural wind, so as to realize the combination of mechanical ventilation and natural ventilation and reduce ventilation energy consumption. At the same time, the inner and outer warehouse walls are connected by a support frame, so that there is an air gap between the inner and outer warehouse walls, which can play a role of heat insulation together;

[0083] (5) The present application sets up a wind distribution chamber and a multi-layer ventilation cage to realize ventilation of grain piles at different heights, and ventilates from the center to the warehouse wall, and the ventilation path is short.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it.
