Abstract

The utility model relates to a high-frequency vibration mill, which is suitable for cereal crushing, wheat crushing, etc. The utility model can select and match vibration sources-a vibration motor or the vibration frame of an electromagnetic vibrator according to the thickness of cereal products; the utility model drives a roller to rotate by a motor after double reduction; the utility model actuates the vibration frame to do the moment peak of reciprocating parabolic motion under the action of the vibration motor or the electromagnetic vibrator; the utility model can carry out cutting, scraping and peeling to realize the purposes of milling and production through the inherent tooth pitch of the vibration frame and the tooth pitch of the roller simultaneously, when cereal is cracked. The power consumption of the utility model is only 1/10 of the electricity energy of the existing versatile mill. The dust content in the cereal products, such as wheat flour, etc. which are milled by the utility model is reduced. Besides, the quality rate is improved.

Description

The dither mill

The utility model relates to the dither mill of being produced in the broken or broken back of a kind of cereal material, particularly material such as wheat, corn.

China's day is produced flour, nearly 5,000 factories of the factory of corn flour more than 80 tons now, and these enterprises are all using at present four rollers in the mill, and every limit is made up of two rollers.And coincide attrition crushing wheat, corn with two rollers.Two rollers, one roller when extruding wheat, corn turns clockwise, and another roller is executed commentaries on classics counterclockwise.As shown in Figure 1, because the speed ratio difference (speed ratio of two rollers is 1: 2.5) of a slow roller of another root of fast roller was added and is processed with the tooth gradient on two rollers when two rollers changeed,, two rollers reach the purpose that cereal is produced so shearing, scrape stripping when rotating attrition crushing wheat, corn.

From China's reform and opening-up during the last ten years, Beijing and national each province have introduced " mill " of many countries as Britain " Siemon Co. ", " mill " its structural principle of Switzerland " Bu Le company " or the like country now uses the structural principle of " mill " the same with China, only Wai Guo " mill " is meticulous in processing, has added some Electronic Control again.No matter broken cereal (wheat, corn etc.) product is pushed by domestic or foreign country's " mill " with two rollers with regard to going forward in a word.Should " mill " be used on the slubbing operation and push wheat, per hour 44 kilowatts of " mill " minimum power consumption.Above-mentioned " mill " be with two roller attrition crushing wheats, this fashion of extrusion with so the wheat fragmentation, but the protein that will be close to the wheat bran internal layer is overlaying more firm with the wheat bran internal layer.So bring difficulty for following multiple working procedure.Therefore one grained wheat is worn into flour and must return and carry out the flour that 12 procedures just can be made again.

The flour that above-mentioned " mill " mainly comes out with extruding, power consumption is big, because its very complicated maintenance work amount of structure is big, expenses is also big.

The purpose of this utility model, it is simple to be to propose a kind of knot, use the attrition crushing wheat of above-mentioned " mill " or corn instead dither and beat broken wheat of power or corn, under the situation of same output, the latter only uses the former 1/10 electric energy, because after dither beats broken wheat, make that the protein that is close to the wheat bran internal layer is loose have been opened, give the barreling of later operation, a lot of bars have been created in screen, so it is a lot of dither mill of advantage.

Above-mentioned purpose realizes in the following manner: utilize existing at present with roller in " mill ", tooth gradient on this roller is to decide according to the needs that beat broken material, be generally 2.5 millimeter one tooth, gradient 1: 10, this roller is connected on the frame with bearing block, and can rotate nimbly and freely, by the random lifting moving of screw mandrel handwheel roller.By sheave, order about a roller turn with the motor after slowing down.There is one to make rack-plate with antifriction alloy and roller matches below the roller, it is according to wheat, the processing of corn product arts demand that the tooth gradient is arranged on this piece rack-plate, the rack-plate that processes is fixed on the vibrating grid, and vibrating grid hangs on the rubber spring seat that is positioned on frame four limits.Middle section position has the swash plate of enough stiffness below the vibrating grid, and vibrating motor or electromagnetic vibrator are fixed on this plate.Roller, motor, sheave, rack-plate, vibrating grid, vibrating motor or electromagnetic vibrator.Six parts have been formed the dither mill.After giving the initiating signal of electrical equipment when material has been arranged, roller begins rotation, and vibrating grid begins with vibrating motor with per second 15.5 times (amplitude 4-5.5 millimeter) or with electromagnetic vibrator per second 25 times (amplitude 1.2-2.7 millimeter), and frequency is done parabolical reciprocating motion.As shown in Figure 2, wheat or corn bound forward roller and rack-plate forward when matching the position along parabolic path, wheat in a flash or corn that vibrating grid is downward jump to below the roller, vibrating grid up jumps again utilizes the tooth on steel alloy rack-plate upper teeth and the roller to shear again when utilizing cusp on the rack-plate that wheat or corn are broken into pieces in a flash, because the different stripping power of scraping with the speed ratio of roller rotational line speed of movement velocity of vibrating grid save dither abrasion electric weight owing to used the power of beaing instead greatly.Make that the protein of being close to the wheat bran internal layer is loose to be opened owing to having used the broken wheat of the power of beaing instead, reduced content of ashes in the flour (is the principal element that influences flour quality because of ash content).Under the immovable situation of production technology, can improve simultaneously the output about 20%.

Can be described further the utility model in conjunction with following example and accompanying drawing:
