Description
Technical field
The invention belongs to technical field of petrochemical industry, and in particular to a kind of powder feeder.
Background technique
In the production process of petroleum chemicals, many chemical reactions need the participation of granular material or catalyst.It is existing to add
The method for adding material is that directly the feed opening of reaction kettle is opened, and is manually added from feed opening.But chemical reaction is usual
It can generate along with poisonous and hazardous gas, and powder-material is also easy to produce dust during addition, therefore need in process of production
To be sealed processing to consersion unit, while existing charging process cannot be guaranteed that continuous uniform feed, Er Qieyou
In the particularity of powder, during charging, powder is easy to happen hardened, influences charging process.
Summary of the invention
The present invention be directed to the above-mentioned problems of the prior art and deficiency, provide it is a kind of charging uniformly and effectively prevent feeding
The hardened powder feeder of powder in the process.
The present invention is achieved by the following technical solutions: a kind of powder feeder, can dismantle including being provided with
The feed bin of top pressure closure, the bin bottom have discharge port, and discharge outlet is connected with feed pipe；Pass through in the feed pipe
Rotation axis is fixed with rotating roller, and rotation axis side is fixed with transmission gear one；Discharge outlet is provided with rotation in the feed bin
Screw rod, rotary screw side are fixed with transmission gear two；The rotation roller surface has several stock chests being disposed adjacent；It is described
Rotation axis on be additionally provided with several driving wheels.
Specifically, the transmission gear one and transmission gear two are intermeshed.Driving wheel is connected with motor, electronic
While machine drives rotating roller, the transmission gear one coaxial with rotating roller is rotated with nutating gear two, and transmission gear two drives
Rotary screw rotation, so that rotating roller and rotary screw be made to drive by same motor.
Specifically, the driving wheel radius is unequal, to control the different rotating speeds of rotating roller and rotary screw.
Specifically, the stock chest is equal in magnitude.
The beneficial effects of the present invention are: device design structure is simple, it can be achieved that uniform discharge, can prevent because powder is hardened
Charging is influenced, while realizing charging in a sealed meter environment, alleviates the pollution of dust and pernicious gas to environment.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is rotating roller schematic diagram of the invention.
1- top pressure closure, 2- feed bin, 3- feed pipe, 4- rotation axis, 5- rotating roller, 6- rotary screw, 7- transmission gear one,
8- transmission gear two, 9- stock chest, 10- driving wheel, 11- flange butterfly.
Specific embodiment
Technical scheme of the present invention will be further explained in detail below by way of examples and with reference to the accompanying drawings.
A kind of powder feeder, the feed bin 2 including being provided with the top pressure closure 1 that can be dismantled, 2 bottom of feed bin
There is discharge port, discharge outlet is connected with feed pipe 3；Rotating roller 5, rotation axis are fixed with by rotation axis 4 in the feed pipe 3
4 sides are fixed with transmission gear 1；Discharge outlet is provided with rotary screw 6 in the feed bin 2, and 6 side of rotary screw is fixed
There is transmission gear 28；There are several stock chests 9 being disposed adjacent on 5 surface of rotating roller；It is also set up in the rotation axis 4
There are several driving wheels 10；Transmission gear 1 and transmission gear 28 are intermeshed, and rotating roller 5 is with rotary screw 6 by same electronic
Machine drives.
In this embodiment, it is preferred that each stock chest 9 is equal in magnitude.
Preferably, 10 radius of driving wheel is unequal.
Preferably, the driving wheel 10 is connect with motor (being not drawn into figure).
Preferably, described 3 one end of feed pipe is provided with dismountable sealing cover, the convenient maintenance and cleaning to rotating roller 5.
Preferably, 2 bottom surface of feed bin is taper, is slipped in stock chest 9 conducive to the powder in feed bin 2.
Preferably, 3 bottom of feed pipe is equipped with the flange butterfly 11 of control feed pipe nozzle size.
The principle of the present invention are as follows: powder is added in feed bin 2, and top pressure closure 1 is sealed, motor is by driving transmission
Wheel 10 drives rotation axis 4 to rotate, and rotating roller 5 is rotated with rotation axis 4, and the transmission gear 1 in rotation axis 4 drives driving cog simultaneously
28 rotations are taken turns, so that rotary screw 6 is synchronized and rotated, rotary screw 6 is in the course of rotation constantly to the powder of discharge outlet
Material plays stirring action, prevents powder because pressure itself bottom is hardened, the powder in feed bin 2 is in rotary screw 6 and self gravity
Under the action of fall into the stock chest 9 in rotating roller 5, as the rotation of rotating roller 5 is gradually trickled down in feed pipe 3 and then is entered
It is equal in magnitude due to each stock chest 9 in other containers such as reaction kettle, in 5 velocity of rotation of rotating roller, one timing, it can be achieved that powder
The uniform addition of material.The different driving wheel 10 of radius is connected with motor, the revolving speed of rotating roller 5 can be changed, to control
The adding speed of powder, rotary screw 6 and rotating roller 5 are driven using same motor, can guarantee that the revolving speed of the two is adapted,
6 velocity of rotation of rotary screw is avoided to cause the hardened velocity of rotation mismatch to the falling speed and rotating roller 5 that make powder slowly,
Influence charging rate.3 bottom of feed pipe is equipped with the flange butterfly 11 of control feed pipe nozzle size, can further control charging
Speed, and control valve can be closed upon completion of the addition, the top pressure closure 1 for opening feed bin 2 again at this time can be reduced effectively
The gas in container such as dust and reaction kettle leak.
The beneficial effects of the present invention are: device design structure is simple, it can be achieved that uniform discharge, can prevent because powder is hardened
Charging is influenced, while realizing charging in a sealed meter environment, alleviates the pollution of dust and pernicious gas to environment.
