Description

Technical Field

[0001] The utility model relates to the technical field of corn raw material processing, in particular to a corn raw material impurity removal and separation system. Background Technique

[0002] The corn raw material impurity removal and separation system is a pretreatment process for deep processing of corn and is the premise and basis for deep processing of corn. In existing equipment, after storage and purification of raw corn, broken corn is obtained, and there is also a situation where some organic garbage is crushed and mixed into corn fiber. This requires that the purified corn coming out of the corn bin needs to be subjected to iron removal, dust removal, metering, and then hydraulically transported to the soaking tank. After soaking, the corn is crushed and finely ground and then enters the fiber washing system. The slurry after fine grinding is separated, washed, dehydrated by a screw extruder, and then sent to the fiber drying process.

[0003] However, in actual production, there is a problem of insufficient treatment of organic garbage, which in turn leads to impurities in the subsequent raw materials and affects the product quality. Summary of the Utility Model

[0004] Based on the above deficiencies in the prior art, the purpose of the utility model is to provide a corn raw material impurity removal and separation system. Through the combined use of a filtering drum and an impurity removal box, at the filtering drum, organic small particle impurities mixed in the corn are removed. Then the corn freely falls by gravity into the impurity removal box, and the remaining organic garbage is blown out by the hot air at the heating air outlet. The blown-out impurities are recycled and treated, greatly improving the impurity treatment ability and solving the problem of insufficient treatment of organic garbage.

[0005] The utility model is realized by adopting the following technical solutions:

[0006] The corn raw material impurity removal and separation system includes a filtering drum. The filtering drum is connected to an iron removal tank through an impurity removal box. The iron removal tank is connected to a crushing separator through a sulfurous acid soaking tank. There is a heating air outlet on the vertical wall of the impurity removal box, and there is a discharge port on the vertical wall of the iron removal tank. The inside of the filtering drum is provided with a filtering mesh.

[0007] The corn enters the filtering drum, the impurity removal box, and the iron removal tank in sequence by gravity for impurity removal. When the corn falls from the filtering mesh into the impurity removal box, it is blown by the heating air outlet to remove organic garbage impurities.

[0008] A hoist is connected to the filtering mesh. The filtering drum is inclined, and a driving motor is connected to the filtering drum.

[0009] The filtering drum is connected to an impurity storage tank through a pipeline, and a blower is connected to the heating air outlet.

[0010] The described heating air outlet is located on one side close to the filtering roller net. An air outlet is provided on the impurity removal box, and an induced draft fan is connected to the air outlet.

[0011] A baffle is provided inside the described impurity removal box. The baffle is fixed to the bottom surface of the impurity removal box, and an impurity outlet is provided on the outer side of the vertical wall of the impurity removal box.

[0012] A water conveying inlet pipe is connected to the described iron removal tank, and the connection part between the discharge port and the iron removal tank is located above the bottom surface of the iron removal tank.

[0013] The described discharge port is connected to a sulfurous acid soaking tank through a delivery pump, and a stirring paddle is provided inside the sulfurous acid soaking tank.

[0014] The working principle of the present utility model is as follows:

[0015] Corn raw materials enter the filtering drum through a hoist. The driving motor drives the filtering roller net to start rotating. After the corn is processed by the filtering drum, it enters the impurity removal box by gravity. The heating air outlet, the blower and the induced draft fan start to work. Through the hot air at the heating air outlet, the organic garbage is blown out, and the blown-out impurities are recycled and processed. Then the corn enters the iron removal tank. The conveying water enters the iron removal tank through the water conveying inlet pipe. The iron impurities precipitate at the bottom of the iron removal tank. Then the corn enters the sulfurous acid soaking tank through a delivery pump. The stirring paddle starts, and the processed corn enters the crushing separator. Among them, the corn enters the filtering drum, the impurity removal box and the iron removal tank in sequence by gravity for impurity removal. When the corn falls from the filtering roller net to the impurity removal box, it is blown by the hot air at the heating air outlet to remove the organic garbage impurities.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] By adopting the corn raw material impurity removal and separation system of the present utility model, through the combined use of the filtering drum and the impurity removal box, at the filtering drum, the organic small particle impurities mixed in the corn are removed. Then the corn freely falls into the impurity removal box by gravity.
