Description
Technical field
The utility model relates to coal preparation technology fields, and in particular to feed proportioning system before a kind of sieve.
Background technique
In coal preparation plant's production process, classifying screen is one of commonly used equipment, and Large Coal Washing Plant is usually arranged more points at present
Grade sieve carries out classification processing to raw coal, and scraper plate is usually used with sieve mode in the feeding system of raw coal sizing screen in the prior art,
Raw coal is delivered to heavy scraper conveyor by the head chute of belt conveyor, several dischargings are offered on drag conveyor
Gate, and feed opening is arranged in handpiece of scraper conveyer position, raw coal is under the drive of scraper plate from the tail portion of drag conveyor to head
When portion direction is mobile, raw coal is respectively enterd in each classifying screen by discharge gate and head feed opening, so realize scraper plate to point
Grade sieve uniformly matches sieve.But since classifying screen abrasion is big, accident rate is high, and the daily maintenance period is short, uses scraper plate to raw coal
With sieve mode existing defects, when the classifying screen failure that handpiece of scraper conveyer is divided into needs parking maintenance, scraper plate conveying
The existing later coal of chain-drive section can still be entered by head feed opening to be divided into classifying screen, and the blocking of classifying screen pan feeding is in turn resulted in,
Drag conveyor long-play will cause coal charge in machine kerve and overstock, and then influence the normal operation of drag conveyor, occur
The dead vehicle of choke breaks chain, burns the accidents such as motor, therefore, can only be to classifying screen when head, which divides into classifying screen, to break down
Drag conveyor is also stopped while maintenance, will so influence being normally carried out for other normal classifying screens, reduces production effect
Rate.
In view of the above drawbacks, the utility model creator obtains originally practical new finally by prolonged research and practice
Type.
Utility model content
To solve above-mentioned technological deficiency, the technical solution adopted in the utility model is, provides feed proportioning system before a kind of sieve,
Including belt conveyor, bifurcated chute, vibration coal feeder and classifying screen, the head of the belt conveyor is arranged the bifurcated and slips
Slot, the bifurcated chute include the first chute and the second chute, and first chute is connect with the classifying screen, and described first
Driven plate gate is set in chute, second chute is connect with the vibration coal feeder, the vibration coal feeder with it is described
Classifying screen connection.
Compared with the prior art the utility model has the beneficial effects that:
1, feed proportioning system can carry out continuous batching to raw coal sizing screen before sieve provided by the utility model, avoid giving birth to
It produces and interrupts, improve production efficiency.
Detailed description of the invention
It, below will be to institute in embodiment description in order to illustrate more clearly of the technical solution in various embodiments of the utility model
Attached drawing to be used is needed to be briefly described.
Fig. 1 is the utility model overall structure view.
Digital representation in figure: 1- belt conveyor;2- bifurcated chute;3- vibration coal feeder;The first classifying screen of 4-;5- second
Classifying screen;The first chute of 21-;The second chute of 22-.
Specific embodiment
Below in conjunction with attached drawing, the above and other technical features and advantages of the present invention are described in more detail.
The utility model provides feed proportioning system before a kind of sieve, including belt conveyor 1, bifurcated chute 2, vibration coal feeder 3
And classifying screen, feed proportioning system is used to carry out the classifying screen ingredient before the sieve, the classifying screen include the first classifying screen 4 and
The head of the belt conveyor 1 is arranged in second classifying screen 5, the bifurcated chute 2, and raw coal is defeated through the belt conveyor 1
Send into the bifurcated chute 2, the bifurcated chute 2 includes the first chute 21 and the second chute 22, first chute 21 with
The pan feeding chute of first classifying screen 4 connects, and driven plate gate is arranged in first chute 21, and described second slips
Slot 22 is connect with the feeding end of the vibration coal feeder 3, the discharge end of the vibration coal feeder 3 and second classifying screen 5
Pan feeding chute connection, wherein the feeding end of the vibration coal feeder 3 is provided with pan feeding gate, the discharging of the vibration coal feeder 3
End is provided with discharge gate.
In process of production, when first classifying screen 4 failure needs to stop pan feeding, first chute is closed
The driven plate gate on 21, raw coal enters in the bifurcated chute 2 through the belt conveyor 1, and then respectively enters
First chute 21 and second chute 22, due to the driven plate closing gate in first chute 21, into
Entering the coal charge in first chute 21 cannot be introduced into first classifying screen 4, instead in overflow to second chute 22, lead to
It crosses the vibration coal feeder 3 and enters second classifying screen 5, and then will not be indulged in since first classifying screen 4 breaks down
The accidentally normal production of second classifying screen 5.Likewise, closing the vibration when second classifying screen 5 breaks down and giving
The pan feeding gate of coal machine 3, raw coal are then directly entered in first classifying screen 4 by first chute 21, and then will not be by
The normal production of first classifying screen 4 is broken down and influenced in second classifying screen 5.
The utility model provides feed proportioning system before a kind of sieve, can continuously be matched to the raw coal sizing screen in coal preparation plant
Material avoids scraper plate batching mode often occurs in the prior art production disruption, the disadvantages of production efficiency is low and at high cost.
The above is only the preferred embodiment of the present invention, is merely illustrative for the utility model, and
It is unrestricted.Those skilled in the art understand that can be to it in the spirit and scope defined by the utility model claims
Many changes, modifications, and even equivalents are carried out, but all will fall within the protection scope of the utility model.
