Description
Technical field
The utility model relates to coal handling system technical fields, and in particular to a kind of herringbone curve coal spout structure.
Background technique
For coal in exploitation, processing and use process, transmission is essential step.Existing frequently-used coal transmits dress
It sets including support frame, splicing belt and coal spout, ground is stood in support frame fixation, to be used to support the entire coal transmission dress of carrying
It sets, coal spout is fixedly installed on the support frame and is located at the top of splicing belt to guide coal to fall on the splicing belt
On, splicing belt is installed on the support frame to transmit coal.When entire coal transmitting device is started to work, coal is fallen from this
The opening of coal pipe upper end enters in the coal spout, and falls on the splicing belt below the coal spout along coal spout, splicing
Belt continuous back and forth or left and right side under the drive of other power devices is rotated up will fall off coal transmission thereon
To pre-set destination, to realize the transmission to coal.
In the prior art, coal transmitting device as shown in Figure 1, inverted V type connecting tube 2 is connected below hopper 1, and inverted V type connects
Two branch pipes of adapter tube 2 are connected respectively inclination coal spout 3, and the lower end of tipping tube 3 is connected with vertical pipe 4, two tipping tubes 3 it
Between angle and 2 two branch pipes of inverted V type connecting tube between angle it is identical, be all 60 degree.When coal falls, in tipping tube 3
The inner tubal wall and vertical pipe 4 of side and the outside inner tubal wall of 3 joining place of tipping tube are primary wear surfaces, the impact force by coal stream
Greatly, the service life is short.Furthermore the corner of vertical pipe 4 and 3 joining place of tipping tube is easy to appear long-pending coal, viscous coal, fluffy coal phenomenon, causes
Coal spout blocks.The excessive sideslip that will cause splicing belt of impact force of splicing belt is dropped down onto since coal flows down, vertical
Be provided with buffering air lock device 5 in the lumen of pipe 4, be used for a long time, the turnover panel of buffering air lock device 5 be easy it is stuck, while in locker
There are many places dead angles in portion, easily cause viscous coal, fluffy coal phenomenon, do not have buffer function, be unfavorable for the conveying of coal charge.
Utility model content
The purpose of the utility model is to provide one kind can reduce coal stream to the frictional force of tube wall, eliminates chute blockage and effectively delays
Punching and structure is simple, herringbone curve coal spout structure with long service life.
To achieve the goals above, the technical solution adopted in the utility model are as follows: a kind of herringbone curve coal spout structure,
Including the inverted V type connecting tube being connected with the lower end hopper A, the lower nozzle of two branch pipes of connecting tube is connected respectively tipping tube, and two
The angle α of the tube core of a tipping tube is less than the tube core angle β of connecting tube branch pipe, and the tube core of tipping tube and horizontally angle theta
Greater than the angle of repose of material.
In above scheme, since the angle α of the tube core of tipping tube is less than the tube core angle β of connecting tube branch pipe, coal stream passes through
Connecting tube changes the direction of coal stream, increases coal stream speed when entering tipping tube effectively eliminates under inverted V type connecting tube
Portion accumulates the phenomenon that coal, viscous coal, fluffy coal, while coal stream reduces the frictional force of inner wall on the inside of tipping tube, and abrasion reduces, and increases and falls
The service life of coal pipe entirety.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of coal spout in the prior art；
Fig. 2 is the structural schematic diagram of herringbone curve coal spout in the utility model；
Specific embodiment
As shown in Fig. 2, a kind of herringbone curve coal spout structure, including the inverted V type connecting tube being connected with the lower end hopper A
10, the lower nozzle of two branch pipes of connecting tube 10 is connected respectively tipping tube 20, and the angle α of the tube core of two tipping tubes 20 is less than
The tube core angle β of 10 branch pipe of connecting tube, and the tube core of tipping tube 20 is greater than the angle of repose of material with horizontally angle theta.Due to
The angle α of the tube core of tipping tube 20 is less than the tube core angle β of 10 branch pipe of connecting tube, and coal stream enters tipping tube 20 by connecting tube 10
When the speed that changes the direction of coal stream, increase coal stream, effectively eliminate 10 accumulating at lower part coal of inverted V type connecting tube, viscous coal, fluffy
The phenomenon that coal, while coal stream reduces the frictional force of 20 inside inner wall of tipping tube, abrasion reduces, and increases making for coal spout entirety
Use the service life.The tube core of tipping tube 20 is greater than angle of repose this set of material with horizontally angle theta, effectively avoids coal stream
The phenomenon that blocking at 20 lower nozzle of tipping tube, is conducive to the conveying of coal stream.
As a preferred embodiment of the present invention, it is connected at the lower nozzle of tipping tube 20 by curve radian plate vertical short
Pipe 30 is provided with cushioning fender 40 in the inner cavity of vertical short tube 30, and cushioning fender 40, which closes on the outside of vertical short tube 30, to be arranged, buffering
The upper end of baffle 40 is fixedly connected at 20 lower nozzle position of tipping tube, lower end protrudes out to outside vertical short tube 30.Due to coal stream
Very big in the impact force for falling to splicing belt, the sideslip for being likely to result in splicing belt is even torn, and the utility model takes
Disappear buffering air lock device 5, and is changed to be provided with cushioning fender 40 in the inner cavity of vertical short tube 30, and coal, which flows down, falls a part in the process
Coal, which impacts, makes the coal stream direction of this part change on cushioning fender 40, reduced velocity flow, the coal stream that direction changes is again
It is impacted with straight coal stream, slows down overall coal flow velocity degree, achieve the purpose that buffering, be effectively protected splicing belt and exempt from
It is damaged, increases the service life of splicing belt.It closes on the outside of vertical short tube 30 and arranges as cushioning fender 40, be because of coal stream
In dropping process, most coal is impacted on vertical 30 outside inner wall of short tube, so not needing to be arranged at the inner wall of inside
Cushioning fender 40, and when 40 long-time of cushioning fender washes away impaired, it replaces also very simple and convenient.
In order to guarantee that coal stream can be reduced coal flow velocity degree by buffering in dropping process, and it not will cause coal stream and exporting
Place's blocking, face where the plate face of cushioning fender 40 and vertical angle δ are acute angle, and 40 lower end of cushioning fender and vertical short tube
There is distance between the extended line of 30 tube cores.
Due to coal stream whereabouts during, mainly impact tipping tube 20 inside and preceding latter linked inner wall, tipping tube
Wear-resistant liner 50 is provided on 20 inner wall, wear-resistant liner 50 is positioned close on the inner wall of inside and front and rear sides.
It is obtained by constantly testing, the angle α of the tube core of tipping tube 20 is 37 °, the tube core angle β of 10 branch pipe of connecting tube
It is 60 °, the tube core of tipping tube 20 is 72 ° with horizontally angle theta.These angles are selected, the whereabouts of coal stream is the most smooth, falls
The service life longest of coal pipe.
For the ease of maintenance test, door to access 21 is provided on 20 outside tube wall of tipping tube.Surfaceman can be from entering hole
Door 21, which enters in coal spout, to be checked, is repaired.
