SU139922A1 - Crushing-screening unit, for example, for squash - Google Patents

Description

Horizontal shredders for shredding squash or sieve or double-shaker used for sifting flour are known. In the proposed unit, a crushing rotoping device, a sieve for sifting flour, equipped with a hopper at the top, a collection for flour at the bottom and a device for reducing the amount of dust released are combined.

A pipe with a screw located on the outer side of the housing, or a pipe and impeller with shortened wings in the collector, may be used to re-feed the unground shvara. In the crushing device, mills can be used instead of hammers.

The use of an aggregate makes it possible to crush the squib while simultaneously sifting out the flour obtained from it with the return of the raw product to secondary grinding. In addition, the replacement of one unit of the machine complex significantly reduces the production area and improves the performance of the squash treatment.

FIG. 1 schematically shows a crushing-screening unit; in fig. 2 - version of the unit.

The unit consists of a housing / mounted on a foundation 2, a hopper 3 with loading hatches 4, 5, a vertically mounted shaft 6. spherical roller bearings 7 located on the shaft and s 8 holder 9 plates with axles passing through them 10 hammers on them //. The impeller 12 is rigidly fixed on the shaft 6. A cylindrical sieve 13 is placed inside the body, in some parts of which there are no holes, and longitudinal grooves are cut from the inside. A pipe 14 with a screw 15 for returning an unsolicited product, an electric motor 16 with a V-belt drive is attached to the outer side of the housing.

No. 139922-2. The operation of the unit is performed according to the following scheme: the squib through the loading port 4 enters the working cavity of the unit. Under the impact of hammer blows / 7, the squash breaks up and is thrown at the sieve 13. The finely ground squash passes through the sieve holes and is discharged through the outlet 17 with the help of a scraper 18 on the shaft 1 :. The remaining, not passed through the holes on the sieve, large particles of squash by the impeller 12 are fed into the auger 15, with which the empty particles of squash return through the hatch 5 for re-grinding.

The process is repeated until the squam is completely crushed. At the same time, 7 u; -a, a version of the unit is proposed, in which some units have been replaced.

Instead of plates with axes and hammers sitting on them on a vertical shaft 6, cruciform plates 20 are rigidly seated, the fingers of which are fixedly fixed to the fingers 21. On these fingers, flat milling cutters 22 are placed with a gap, separated by washers 23.

Instead of an unsweeted wastewater return device consisting of a pipe 14 and a screw 15, a return pipe 24 is attached to the outside of the casing, through which the empty squash particles are transferred through a hatch 5 through the hatch 5 to regrind it.

The scraper 18, which sits on the shaft 19, facilitates the unloading of the finished product, is replaced by an unloader mechanism consisting of a case-shell 25, rotating blades 26 connected by a coupling 27 with a vertical shaft 6.

The All-Union Scientific Research Institute of the Meat Industry VNIIMP, in conclusion to the industrial utility of the proposal, notes that the option of transporting the unsuccessful shredding of squaws using a screw is more reliable from an operational point of view, compared to the trapsporium pipe using an impeller.

Subject invention

Claims (4)

1. A crushing-screening unit, for example, for a squash consisting of a body, a hopper and a collection, characterized in that, in order to crush the squash and simultaneously sift out the flour produced from it, it includes a crushing and screening device with a loading conic a bunker at the top and a collector for flour at the bottom, with the crushing device made in the form of a vertical shaft with nlastinas rigidly stuck on it with holes and axes passing through them parallel to the shaft with pivotally hammers E), and the screening device is composed of a four-part cylindrical screen surrounding the crushing device, and is provided at the bottom for collection uspevschey not undergo grinding Shkvarov. 2.
