Abstract
The present invention relates to a kind of thermal power plant and the colliery rotary coal feeder that the coal blending coal supply is used in carrying the coal process.This machine is the power transmission shaft 6 that opened type hopper 7 is housed on the support 14 that has a inclination angle and connects with bearing and bearing block 4.The double threaded screw rotary body 9 of diffused is housed on the power transmission shaft, and power transmission shaft one end is equipped with cycloidal planetary gear speed reducer 13.Meet 16 times companies of storage bin on the hopper and carry adhesive tape 1.This batcher is simple and compact for structure, and installation and maintenance are convenient, and cost hang down the effect height, can continuous-feeding and be difficult for obstruction.
Description
The present invention is a kind of rotary coal feeder, is specially adapted to the coal blending in carrying the coal process of thermal power plant and colliery, the rotary coal feeder that coal supply is used.
At present, the coal blending coal supply equipment that thermal power plant and colliery are selected, external as GE, MIT, advanced countries such as Italy, Switzerland, domestic as Electric Power Design Institute such as East China, northwest, northeast, south China, and selected coal blending, the coal supply equipment in thermal power plant that moves at present, outer is coal supply, coal blending machineries such as bent axle is reciprocating type, impeller clearance type, buried scraper, Electromagnetically vibrating.Reciprocating structure heaviness, wasted work rate are big, because of being interrupted coal supply, conveyer belt and motor are impacted again; The clearance type construction investment is huge, and operation maintenance work is big; Scraper-type is heaviness but also fragile not only; Electromagnetically vibrating changes in the big large and medium-sized near coal-mine power plant very easily chute blockage and burns solenoid in coal, and electric and magnetic oscillation produces nearly 120 decibels noise and has a strong impact on the healthy of field personnel.Above-mentioned several coal blending, coal supply equipment cause in various degree threat for the safety in production of power plant.
The objective of the invention is to design a kind of simple in structure, compact, unit is in light weight, cost is low, installation and maintenance are convenient, effect is high, noise is little, adapt to coal changes and stop up greatly and not, rotary coal feeder safe and reliable to operation substitutes above-mentioned several common equipments.To guarantee the safety in production in thermal power plant and colliery.
Fig. 1 is the overall construction drawing of feeder.
Fig. 2 is that the feeder rotary body turns to selection figure.
Marking sequence number in the accompanying drawings is expressed as follows respectively:
1, carry that adhesive tape 2, support frame 3, running direction indicator 4, bearing and bearing block 5, blanking port 6, power transmission shaft 7, material are poor 8, fixture 9, double threaded screw rotary body 10, feed hopper 11, drive plate 12, flexible clutch 13, cycloidal planetary gear speed reducer 14, support 15, material blanking tube 16, storage bin.
Below in conjunction with accompanying drawing technical scheme of the present invention is described.
The present invention has powerful propulsive force and the design of steady characteristics of high efficiency according to the worm screw oil pump.Be installed on support 14 center lines by two bearings and bearing block 4 by poor 7, the power transmission shafts 6 of dress opened type material on the support 14 that has the α angle of inclination.Double threaded screw rotary body 9(is called for short down rotary body) with double end end chain directly be bumped on the drive plate 11 two breach chains poor in and fixture 8 fastening methods be installed on the power transmission shaft 6.This rotary body 9 flows are big, the work balance, and this fastening positioning mode is simple in structure, and dismounting is easy to maintenance.The twin-feed spiral angle of rotary body adopts level and smooth incremental method to make diffused.Rotary body 9 is the 50-60 millimeter with the distance of poor 7 bottoms of material, to form a scuff-resistant coating, improves and expects poor service life, and the uncovered size on the poor uncovered plane of material is 2～2.5 to 1 with the rotary body diameter ratio, in case the stops material is stuck at the place, both sides.Cycloidal planetary gear speed reducer 13 is connected power transmission shaft 6 one ends by flexible clutch 12, the power transmission shaft other end indicates the traffic direction that running direction indicator 3 can be known the indication batcher, batcher turn to the left-handed and dextrorotation of branch, so that the designer selects levoform or dextrorotation formula for use according to the situation design of production scene, its system of selection is P
1Direction and rotary body turn to forward, to lower the power attenuation of axle system.With power transmission shaft 6, rotary body 9, reductor 13 all becomes with horizontal plane-the α inclination angle with the axle system and the material poor 7 of bearing and bearing block 4 compositions.This structure can be improved the flowability of material and the axial thrust of balance rotating body.Support frame 2 generally is made up of steel structure frame and is supported on conveying adhesive tape 1 top, and material falls into by blanking port 5 and carries adhesive tape 1, and supplied materials connects feed hopper 10 and storage bins 16 by material blanking tube 15.
Feeder of the present invention is simple and compact for structure, and unit is in light weight, cost is low, and installation and maintenance are convenient, power height, noise are little, adapt to the coal variation and stop up greatly and not, safe and reliable to operation, and can be designed to series of products of all sizes according to the needs in each power plant and colliery.
