Powder delivery equipment proposed by the invention; It comprises at least one broach hopper, and this broach hopper comprises top material loading section and bottom blanking section, and the blanking section has spraying equipment and blade in the bottom; Wherein spraying equipment is below blade; The nozzle of spraying equipment is subordinate's section of expecting inwall jet gas down, and blade is connected with S. A., rotates through S. A..
Wherein, spraying equipment is connected with S. A., and S. A. is a hollow, for spraying equipment provides jet gas.
Wherein, the nozzle of the spraying equipment jet gas that makes progress.
Wherein, blade has the nozzle of subordinate's section of expecting inwall jet gas down.
Wherein, the downward jet gas of the nozzle on the blade.
Wherein, blade plan form shape, straight tabular or swash plate shape in the shape of a spiral.
Wherein, the outlet section of blanking section has flow measurement in the bottom.
The flow that measures when flow measurement drops to when a certain amount of, starts anti-blocking equipment, can only start spraying equipment, only start blade, also can start spraying equipment and blade simultaneously; When starting blade, the nozzle that can start blade also can not start the nozzle of blade.
According to the character of powder material the condition of startup is set, in general when flow drops to the 80%-40% of normal discharge, starts anti-blocking equipment, can maximal efficiency cut down the consumption of energy.Carry for power plant boiler fine coal, in general when flow drop to normal discharge 70% the time startup; And carry for the flying dust of flying dust treating system, in general when flow drop to normal discharge 50% the time startup.
This equipment is through being provided with two kinds of anti-block apparatus of nozzle and blade simultaneously, according to actual conditions select to start the two one of or start simultaneously, improved anti-blocking efficient, reduced energy consumption.Judge stopping state through discharge measurement, select start anti-block apparatus suitable opportunity, improved anti-blocking efficient, reduced energy consumption.Nozzle is set on blade, in rotation, sprays, improved anti-blocking efficient, reduced energy consumption.
Description of drawings
Fig. 1 representes the structural representation of this equipment.
The specific embodiment
This equipment is referring to Fig. 1.Its structure comprises: at least one broach hopper; This broach hopper comprises top material loading section 1 and bottom blanking section 2; Blanking section 2 has spraying equipment 5 and blade 4 in the bottom, and wherein spraying equipment 5 is below blade 4, and the nozzle of spraying equipment 5 is subordinate's section of expecting inwall jet gas down; Blade 4 is connected with S. A. 3, rotates through S. A..Spraying equipment 5 is connected with S. A. 3, and S. A. 3 is a hollow, for spraying equipment provides jet gas.The nozzle of the spraying equipment jet gas that makes progress.Blade has the nozzle of subordinate's section of expecting inwall jet gas down.The downward jet gas of nozzle on the blade.The outlet section of blanking section has flow measurement 6 in the bottom, and blade plan form is the swash plate shape.
When carrying powder material, flow measurement 6 is measured flowrate variation, when flow drops to when a certain amount of, starts anti-block apparatus, can only start spraying equipment 5, only start blade 4, also can start spraying equipment 5 and blade 4 simultaneously; When starting blade 4, the nozzle that can start blade 4 also can not start the nozzle of blade 4, thereby prevents that efficiently powder material from stopping up.
Comparative Examples 1:
