Description

(54) VIBRATION HOPPER

The invention relates to the storage and unloading of bulk materials from bunkers and can be used in such areas of the national economy as building, food, and chemical. According to the main author. St. No. 688382, a vibrating bunker is known, comprising a housing, a bottom part, support members and vibrators, the bottom part being made of sections with vibrators freely suspended from the body and the vibrators are kinematically interconnected by a synchronizing, e.g. the casing is made in the form of a tube of elastic material, and the bunker is equipped with a conical flow divider located in its lower part with brackets attached to the bottom section of sections and a feeder in the form of sections of the bottom part of the fixed disk with a central discharge window and drive plate knives mounted above the disk symmetrically to the vertical axis of the p1 splitter. The disadvantage of this vibratory hopper is that the mixture is compacted directly above the blade knives and arching. The purpose of the invention is to provide material collapse. The above objective is achieved by the fact that rippers fixed in a form of rods located between the flow divider and the body at different distances from the vertical axis of the bunker are rigidly fixed on the blade knives in the vibrating bin. 1 shows a bunker, longitudinal section; in fig. 2 shows section A-A in FIG. one; in fig. 3 - node 1 in figure 1. The vibratory hopper includes a housing 1, support members 2, a bottom part, made of sections 3 and 4,

Ibrators 5 and 6, mounted on the ektsi and interconnected by a flexible synchronizing gear. The bunker is also provided with a feeder in the form of a fixed disk 10 with a central unloading window 11 and drive lamellar knives 12 installed above the bottom sections installed above the fixed disk Yu symmetrically to the vertical axis of the flow divider. Blade knives 12 are driven. movement from the drive 13. On lamellar knives 12, the rippers are firmly fixed in the form of rods 14 located between the flow divider 8 and the housing 1 at different distances x. vertical axis of the bunker.

Vibrating bunker works as follows.

By vibrating sections 3 and 4 of the bottom part and the entire mass of material located directly above the blade blades 12, the material reaches its mobility in the hopper, while the bottom part oscillates synchronously in antiphase during rotation of the unbalances of vibrators 5 and 6. The lamellar knives 12, when unloaded, rotate slowly, pick up the lower layers of material and move them through their inner side faces along the fixed disk 10 of the feeder to the discharge window 11. Thanks to the fact that the lamellas 12 are rigidly fixed loose, made in the form of rods 14 located between the flow divider and the housing, loosening and complete destruction of the material above the blades are ensured. Placing the rods 14 on the plate knives at different distances from the vertical axis of the hopper allows loosening all the material between the flow gage and the body.

The proposed bunker providing.

Material destruction, uniform supply of material over the entire cross section of the bunker, which ensures uniform distribution of material.
