Description

Technical Field

[0001] The utility model relates to the technical field of grain and oil processing, and specifically, to a system for impurity removal, crushing, recycling and utilization of raw materials in the grain and oil processing industry. Background Art

[0002] Taking soybeans as an example, the impurities contained in soybeans are divided into three categories: organic impurities, inorganic impurities and oil-containing impurities. Most impurities do not contain oil themselves. During the processing, not only do they not produce oil, but they will adsorb a certain amount of oil in the meal. Impurities such as soil, stems, leaves, husks, etc. will cause the color of the oil to deepen and produce bad smells; hard objects such as stones and iron will wear the equipment. Therefore, effective cleaning and impurity removal should be carried out before processing to reduce oil loss, increase the oil yield, and extend the service life of the equipment. Generally, after weighing, the soybeans are separated from the soybean stalk impurities (such as soybean pods and soybean stalks, referred to as large soybean impurities) in the soybeans through a vibrating screen, and the soybean stalks are deposited in the general solid waste temporary storage room for temporary storage.

[0003] Based on the above, the inventor found the following problems: The existing practice is to finally incinerate the large soybean impurities. However, smoking and fire are strictly prohibited in the plant areas of oil processing enterprises. Therefore, the incineration of soybean impurities is almost entrusted to a third party for payment, which increases the production cost. At the same time, the incineration of soybean impurities will cause great pollution to the atmospheric environment, does not meet the requirements of national environmental protection regulations, and wastes the fiber substances in the soybean impurities.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a system for impurity removal, crushing, recycling and utilization of raw materials in the grain and oil processing industry is provided, with the expectation of achieving a more practical value.

[0025] Embodiment 3

[0026] Referring to Figure 1 shown, the air inlet end of the cooling and air-drying device 115 is connected to a heater 118. The input end of the heater 118 is connected to a cooling fan 119. The input end of the cooling fan 119 is connected to a dry filter 120. A tail gas treatment device 116 is installed at the air outlet end of the cooling and air-drying device 115.

[0027] Specifically, the working principle of the raw material impurity removal, crushing and recycling system for the grain and oil processing industry: During use, the raw material of large soybean impurities is transported to the air separator 100. According to different specific gravities, it is screened into the following substances: 1. Large soybean impurities, namely organic impurities such as pods, straws, and husks; 2. Inorganic impurities such as soil, stones, and iron impurities. For the inorganic impurities, they are sent into the first inactivation tank 101 and fumigated with direct steam in the first inactivation tank 101. After an inactivation temperature of 121°C, an inactivation humidity of 95%, and an inactivation time of 30 minutes, the quarantine pests and other harmful organisms that may exist in them are completely killed, achieving the purpose of inactivation. Finally, they are treated as solid waste. For the large soybean organic impurities, they are transported to the first cyclone bag filter 103 through the pneumatic conveying pipe 102. First, the centrifugal force generated by the rotating airflow is used to separate the dust particles from the airflow to separate dust particles with a particle size greater than 10 μm. Then, when passing through the cloth bag, the fine dust particles in the waste gas are filtered out to achieve the emission target required by environmental protection. Finally, the tail gas is discharged into the atmosphere through the first induced draft fan 104. The first cyclone bag filter 103 will intercept the organic impurities and transfer them into the straw storage bin 106. When the material level of the straw storage bin 106 reaches 80%, the shredding auger 107 is started to make the crushed impurities enter the iron remover 108 to prevent the iron impurities in the impurities from entering the crusher 109. The iron products separated by the iron remover 108 are outsourced for treatment. The impurities passing through the iron remover 108 have separated the iron products and are sent into the crusher 109. The impurities are crushed into granular form about 3 mm in size. The crushed impurities enter the second cyclone bag filter 110. First, the centrifugal force generated by the rotating airflow is used to separate the dust particles from the airflow to separate dust particles with a particle size greater than 10 μm. Then, when passing through the cloth bag, the fine dust particles in the waste gas are filtered out to achieve the emission target required by environmental protection. Finally, the tail gas is discharged into the atmosphere through the second induced draft fan 111. The second cyclone bag filter 110 will also intercept the crushed organic impurities such as pods, straws, and husks and transport them into the second inactivation tank 114 through the screw conveyor 113. In the second inactivation tank 114, it is fumigated with direct steam. After an inactivation temperature of 121°C, an inactivation humidity of 95%, and an inactivation time of 30 minutes, the quarantine pests and other harmful organisms that may exist in them are completely killed, achieving the purpose of inactivation;After inactivation, the organic impurities are sent to the cooling air drying device 115. The cooling fan will send the fresh air that has passed through the dry filter 120 into the heater 118 for heating. After the temperature rises and becomes hot air, it is sent to the cooling air drying device 115 to heat the organic impurities. Then the heater 118 is turned off, and the room temperature fresh air that has passed through the dry filter 120 is sent to the cooling air drying device 115 to cool the organic impurities. After the intermittent treatment process of heating and cooling, the organic impurities can be controlled below 40°C and the humidity is 8%-10%. Then, they are sent to the bean curd silo 121 as raw materials for storage and reuse. The fresh air passes through the cooling air drying device After 115, it contains certain polluting and harmful components, which cannot be discharged directly. It will be sent to the tail gas treatment device 116 for treatment to remove harmful substances, and finally discharged through the third exhaust pipe 117. The utility model can effectively achieve the need to outsource the treatment of soybean waste, save costs, avoid the incomplete combustion process that may produce a large amount of nitrogen oxides, sulfur dioxide, hydrocarbons and smoke, and may also produce secondary pollutants such as ozone under the action of sunlight, effectively reduce the amount of pollutant emissions, and the treatment method is more environmentally friendly. It can also reuse organic impurities such as bean pods, straws, and husks to increase soybean meal production. ;
