Abstract

The utility model belongs to transport machinery. The purpose of the utility model is to solve the clogging problem thoroughly the of large-sized silo. The dispersing material is ensured to be outputted uniformly continuously. The cycle coal feeding machine is composed of a plough coal cart, a coal supply cart and a coal unloading plough. In order to solve the difficulties in the designing of manufacture of the large scale equipment, the utility model adopts a floating revolving mode. A small distance floating of the diametrical direction of the annular cart body is permitted. In order to ensure the normal rotation, the driveline adopts the driving means of three-point type synchronization, disposing the straight rack in annular and the engagement system of straight gear. The practical requirement is ensured and the cost is driven down.

Description

Cycle coal feeding machine

The utility model belongs to Transport Machinery.

The purpose of this utility model is the blockage problem that thoroughly solves large-scale silo, guarantees to export from silo equably continuously bulk material.

Existing ten thousand tons of silos outlets are generally several mini-funnels types outlets, feeding devices such as the following configuration electro-vibrating feeder of outlet.Because exit area and silo basal area differ greatly, therefore most of silo dischargings are obstructed, are easy to generate latch up phenomenon.The utility model changes ten thousand tons of silo outlets into the large-sized annular slit, has increased exit area exponentially, and has designed novel bulk material outdevice---ring type feeder.Guarantee continuously outputting material from silo equably.

The utility model is ring type feeder of ten thousand tons of silos configuration.This ring type feeder forms for coal car and Liang Tai plough three parts of unloading coal by a plough coal car, one.

The ring type feeder is installed in the annular gap place of ten thousand tons of silo bottoms, sees that accompanying drawing 1 ring type feeder principle of work is as follows: the plough coal car is that central diameter is the annulus car body of 15m, sees accompanying drawing 2B-B sequence number (4); The ring internal fixation has three three plough bodys that can change with the ring body angle, sees accompanying drawing 2B-B sequence number (5); The plough body Shen is gone in the annular gap of ten thousand tons of silos, sees accompanying drawing 1A-A sequence number (1); The annular car body is supported on the circular orbit with wheel, and makes the backstop of horizontal direction with roller.Annular is furnished with annular on the car body.Spur rack.The bikini synchronous driving mode is adopted in the driving of plough coal car: i.e. three driving stations of forming by motor, reductor, straight gear, see accompanying drawing 2B-B sequence number (3), and it is spaced apart 120 °; The straight gear of each driving station all with the annular spur rack engagement of annular car body, and drive its running.At this moment, annular car body drives plough body and rotates on circular orbit, and plough body is fallen followingly on the coal car the plough of the coal in the annular gap down simultaneously, sees accompanying drawing 1A-A sequence number (2).The annular car body allows floating of small distance in any diametric(al).To coal car is that central diameter is the annular car body of 13.8M, and top is that the annular of wide 1.4M is held the coal platform, and the bottom is supported on two circular orbits with wheel, and makes the backstop of horizontal direction with roller.Driving device is with the plough coal car.Unload coal plough by two seat supports across on to coal car, see accompanying drawing 4D-D sequence number (7), plough body can swing up and down, and upwards by the electric pushrod traction, falls by conducting oneself with dignity.In the time of on the plough plough body of unloading coal drops to coal car, can be all ploughing to the coal on the coal car in the other coal breakage bucket of car, see (8) two of accompanying drawing 1D-D sequence numbers unload coal the plough be installed at two positions, two belt transporters under distinguishing accordingly, see accompanying drawing 3C-C sequence number (6), can switchover operation, the ring type feeder adopts AC variable-frequency speed regulation system control, can regulate the flow that produces coal and change within 0～500 ton hour.When by control system control plough coal car with when giving coal car with suitable speed ratio run-in synchronism, output coal stream can reach continuously evenly, protects to levy belt transporter and normally move.

The utility model has the advantages that: 1,, reduced possibility of jamming owing to adopted large-scale ring type slit to increase the material outlet sectional area greatly.2, owing to adopted AC variable-frequency speed regulation system can realize infinite speed variation, therefore export the coal flow can be within 0～500 ton hour continuous and even variation.3, owing to plough coal car and give suitably speed ratio run-in synchronism of coal car, therefore can make output coal stream reach continuously even.4, when several this silo coupling, can have batching, batch mixing function.

Claims

1, ring type feeder.Ring type feeder of ten thousand tons of silos configuration.The ring type feeder forms for coal car and the Liang Tai plough of unloading coal by a plough coal car, one.

The plough coal car is that central diameter is the annular car body of 15M, the ring internal fixation has three three plough bodys that can change with the ring body angle, the annular car body is supported on the circular orbit with wheel, and makes the backstop of horizontal direction with roller.On the annular car body spur rack that is circular layout is arranged.Plough coal car by three driving station driven in synchronism, three driving station 120 ° of distributions at interval on circumference, driving station is made up of electrical motor and reductor, and the straight gear that reductor goes out axle head drives annular spur rack motion.Owing to be spur rack and straight gear engaged transmission, annular car body allows floating of small distance in diametric(al).

To coal car is the annular car body of central diameter 13.8M, and top is Cheng Meitai, is supported on two circular orbits with wheel, and makes the backstop of horizontal direction with roller.Driving system is with the plough coal car.

Unload coal plough by two bearings across on to coal car, plough body can rotate up and down, upwards by the electric pushrod traction, downwards by conducting oneself with dignity.In the time of on plough body drops to coal car, can be all ploughing to the coal on the coal car in the other coal breakage bucket of car.Two ploughs of unloading coal are installed in two positions, and two belts under accordingly can switch mutually respectively.

The ring type feeder adopts AC variable-frequency speed regulation system control, can regulate the flow that produces coal.When the plough coal car with when giving coal car with suitable speed ratio run-in synchronism, output coal stream can reach continuously evenly, guarantees that belt normally moves.

Feature of the present utility model is:

A, ring type feeder of ten thousand tons of silos configuration.
