Description

Swing hopper

Technical field

The utility model relates to solid granular mass transport field, especially a kind of hopper for conveying solid substance granular material.

Background technology

The most of structure of hopper of current feed is the infundibulate of vertical laying, the upper end of hopper is inlet point, lower end is discharging opening, lower end discharging is arranged on the top of the belt conveyor of feeder, when material is thrown something and fed to hopper from top to bottom, by the gravity fall of self of material on the belt conveyor of feeder, thus be sent in boiler, because hopper mostly is up big and down small cone tubular structure, when material more flows downward, flow area is less, and material and headwall, friction force between material and material and squeese pressure are increasing; When material particles is little, ash large, high humidity, stickiness large time, the non-constant of flowing power in material and hopper, often understand blockage phenomenon, material is once blocking can have a strong impact on device security.When material blockage phenomenon, in prior art, the normal method adopted is as vibrator, artificial sledgehammer, air bubbles etc. are implemented to produce vibration to the shock of hopper outer wall to make the material of hopper inside, thus reach the problem alleviating blocking, but for humidity, during the larger material of stickiness, it is stocky that vibrator makes the material originally just blocked in hopper further obtain vibration, originally the material of blocking has vibrated into stock column, situation is also further severe, therefore fundamentally blockage problem cannot be solved by the mode of knocking of vibrating, particularly humidity and the large material of stickiness on the contrary can be further serious.

Summary of the invention

The purpose of this utility model is that providing a kind of swings hopper, can guarantee that material implements blanking smoothly.

For realizing above object, the technical solution adopted in the utility model is: a kind of swing hopper, comprise the hopper unit that above-below direction is disposed in order, hopper unit is the Taper Pipe shape setting of upper big, lower small, the lower nozzle of the hopper unit of adjacent layout is inserted in upper orifice, connected by floating coupling unit between hopper unit, described hopper unit is also provided with exciting agency, the oscillation action that described exciting agency provides hopper unit to float.

Compared with prior art, there is following technique effect in the utility model: is connected by floating coupling unit between adjacent skips unit, when material unimpededly cannot cause Severe blockage in hopper unit, utilize the oscillation action of exciting agency enforcement to hopper unit, can make hopper unit under the effect of impulsive force, form the thrust of different directions, hopper unit at different levels presents the attitude of swing on floating coupling unit, and then the die plane of adjacent hopper unit can be made to present the swing attitude of dislocation, and then the agglomerating force of material can be destroyed, and then can be broken by stock column, play prevention and eliminate material agglomerate, knot arch, put up a bridge, the generation of stock column phenomenon, guarantee that material is unimpeded smoothly in hopper unit, this hopper is particularly useful for Fossil-fired Power Plants and burns the more coal charge of coal slime and fine coal inferior, it is a kind of environmentally friendly machine.
