Movable efficient environment-friendly grain impurity cleaning device

Abstract

The embodiment of the invention discloses a movable efficient environment-friendly grain impurity cleaning device. The movable efficient environment-friendly grain impurity cleaning device comprises adrum screen, a vibrating screen and a circulating winnowing system which are sequentially arranged from top to bottom; the drum screen comprises a screen drum, a rotating shaft is arranged in the screen drum, and an auger blade is arranged on the rotating shaft; the screen drum is in driving connection with a first rotating motor; the rotating shaft is in driving connection with a second rotatingmotor; and the circulating winnowing system comprises an air suction device, an air blowing device, a filtering device and a dust filtering device, a winnowing channel is arranged between the air suction device and the air blowing device, the air suction device and the air blowing device are connected through the filtering device, and the dust filtering device is connected with the air blowing device through a pressure reducing pipe. In this way, during use, the screen drum and the rotating shaft can rotate, so that the flowing speed of grains in the screen drum is changed, and the utilization rate of the screen surface is increased; and meanwhile, dust pollution of the equipment operation environment during use is avoided through the pressure reducing pipe and the dust filtering device.

Description

technical field [0001] The invention relates to a cleaning device, in particular to a mobile high-efficiency and environment-friendly food impurity cleaning device. Background technique [0002] In the process of grain production, it is necessary to clean various sizes of soil, sand and chaff in the grain, so as to reduce the impurities in the grain. At present, when screening grain, it is often necessary to use different screening equipment for coarse screening, fine screening and winnowing of the grain, but in the process of screening through these equipment, the grain is easy to accumulate when the cylindrical screen for coarse screening is used. At the feed inlet and the first half of the screen cylinder, the screen surface of other parts of the screen cylinder is in an empty state, which leads to the problem that the utilization rate of the screen surface in the screen cylinder is not high. There is often a large amount of dust in the gas discharged from the system dur...

Problems solved by technology

[0003] In order to solve the above technical problems, the embodiment of the present invention provides a mobile high-efficiency and environment-friendly grain impurity cleaning device, which can make reasonable use of the position on the mobile car body and pass through the grain collection space at the lower part of the cylindrical sieve to vibrate The processing of fine sieves improves the space utilization rate of the entire equipment and improves the problem of large floor area and inconvenient movement. At the same time, the air pollution degree of the exhaust gas after the air sieve is also reduced through the gas purification device.
