Abstract
A kind of efficiently discharging rotary valve is the utility model is related to, including valve body, impeller, rotating shaft, impeller are installed in valve pocket, are connected by rotating shaft with motor output shaft, feed pipe, lower end connection outlet passage are connected on the intake channel of valve body upper end；Blast pipe mainly is set in feed pipe side, the blast pipe is connected by the steam vent in feed pipe and valve body import passage with valve pocket.Gas when impeller rotates in valve pocket is discharged from blast pipe, improves material conveying effect, and unloading efficiency is high.Suitable for powdery, the valve of granule materials conveying operating mode.
Description
Technical field
The utility model belongs to valve field, more particularly to a kind of discharge valve.The utility model is applied to powdery, particulate matter
The valve of material conveying operating mode.
Background technology
Discharge gate is applied to the handling of the powderies and granule materials of equipment such as each plant feed bin, dryer, by motor driven
Impeller rotation conveying material, in course of conveying, because discharge valve friction rotor power is big, it is necessary to which heavy-duty motor moves as valve
Power, impeller rotation are mingled with a large amount of gases when conveying material, and transfer efficiency is very low.
The content of the invention
The purpose of this utility model is the shortcomings that presence for prior art, there is provided a kind of high efficient discharging of transfer efficiency
Rotary valve.
Technical solutions of the utility model include valve body, impeller, rotating shaft, and impeller is installed in valve pocket, passes through rotating shaft and motor
Axis connection is exported, feed pipe, lower end connection outlet passage are connected on the intake channel of valve body upper end；Mainly set in feed pipe side
Blast pipe is put, the blast pipe is connected by the steam vent in feed pipe and valve body import passage with valve pocket.
In above technical scheme, rotating shaft both ends are installed on valve body by bearing, the rotating shaft on the inside of bearing with
Axle envelope is set between valve body, and axle envelope uses PTFE material, and the valve body lower portion between axle envelope and bearing sets discharging opening.
The utility model has the advantages that valve pocket connects blast pipe, gas when impeller rotates in valve pocket is discharged from blast pipe,
Material conveying effect is improved, unloading efficiency is high.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the installation diagram between rotating shaft and valve body in the utility model Fig. 1.
Embodiment
Efficient discharging rotary valve as shown in Figure 1, including valve body 4, impeller 5, rotating shaft 8, impeller 5 are installed in valve pocket, are led to
Cross rotating shaft 8 to be connected with motor output shaft, feed pipe 3 is connected on the upper end intake channel of valve body 4, the feed pipe 3 is by bolt 2 and nut
1 is fixedly mounted on the intake channel of valve body 4, and the lower end connection outlet passage of valve body 4, motor driven impeller 5 rotates, by material from valve
The intake channel of body 4 is sent to exit passageway；Blast pipe 10 mainly is set in the side of feed pipe 3, the blast pipe 10 passes through feed pipe 3
Connected with the steam vent 11 in the intake channel of valve body 4 with valve pocket, in the rotary course of impeller 5, the gas in valve pocket passes through exhaust
Hole 11 is discharged from blast pipe 10, improves material transfer efficiency.The blade tip of impeller 5 uses knife-edge structure, can scrape in operation
The residual material of the internal chamber wall of valve body 4, there is self-cleaning function.
The both ends of rotating shaft 8 are installed on valve body 4 by bearing 6, are set between the rotating shaft 8 of the inner side of bearing 6 and valve body 4
Axle envelope 7, axle envelope use PTFE material, and PTFE material is smaller relative to the coefficient of friction of metal material, make axle envelope 7 and rotating shaft 8
Frictional force reduces, and reduces energy consumption of electrical machinery.Secondly the good seal performance of PTFE material, ensure that sealing effectiveness.In axle envelope 7 and axle
The bottom of valve body 4 held between 6 sets discharging opening 9, will be discharged from the material that axle envelope 7 leaks from the discharging opening, prevents medium from entering
Bearing 6 influences its performance and used life, as shown in Figure 2.
