Description
Technical field
The utility model belongs to powder industry technical field, and in particular to a kind of powder is continuous, uniformly, accurately feed fills
It sets.
Background technique
Continuous-feeding, essence with the continuous development of the industries such as fine chemistry industry, pharmacy, food, daily use chemicals, coal, to powder
True measuring requirement is higher and higher.It is suitble to the common charging gear of powder to have screw feeder and vibrating feed in modern industrial production
Device is most widely used especially with screw feeder.The basic principle is that the rotation of the helical axis using installation helical blade, makes object
Material generates the relative motion along helicoid, and material is acted on by the frictional force of hopper and dosing tube wall to be revolved together with spiral
Turn, and axially promoted along helical axis, realizes the quantitative conveying of material, pass through the revolving speed of rotating electric machine, spiral spacing and feed
The size of pipe can calculate or be determined by experiment delivery rate.The method is suitable for the rough feed of a large amount of powders, can not
Guarantee feed precision.Currently, having developed the screw feeder system of integrated Weighing system and frequency control motor, i.e. basis in the market
Powder weight required for process units and feed time calculate charging rate, preset motor speed, pass through the reality of Weighing system
The gap of numeric feedback practical charging value and theoretical values is surveyed, then motor speed is adjusted to control charging speed by frequency conversion frequency modulator
Degree keeps practical charging value and theoretical values close as far as possible.The deficiency of the method is that feeding system precision is not high, energy consumption is high, place
The problems such as managing low efficiency.
In the experiment of modern industry, lab scale and pilot process, it is often necessary to the process of industrial time production is imitated, to guarantee
The accuracy and reliability of experimental data, it is necessary to which accurate, continuous, even feeding, at present laboratory and scientific research are carried out to powder
Institutes is also usually fed using manual weighing, short cycle, multiple manual intervention mode.
Summary of the invention
In order to solve these technical problems, the utility model provides a kind of continuous, uniform, the accurate feed dress of powder
It sets, is arranged by using the design of cleverly structure, high-precision weighing sensor type selecting and control unit, while solving vibration
Powder breaking small, in feed bin is precisely weighed the technical issues of being fed four aspects with continuous uniform.The technology that the present invention uses
Scheme is: a kind of continuous, uniform, the accurate charging gear of powder, including pedestal, collector, feed hopper, dispenser, weighing biography
Sensor, bracket, shaft coupling, driving device, control unit, which is characterized in that weighing sensor one end is fixed on the base, another
End support feed hopper, dispenser, bracket, shaft coupling and driving unit.Arrangement quantity of the weighing sensor on pedestal is 1~8
It is a.Dispenser includes screw auger, shaft, broken arch item, connecting rod, and shaft coaxially fixes with screw auger, connecting rod one end and
Shaft is fixed, and the other end is connected with broken arch item.The arrangement quantity of broken arch item is 1~10, the every attachable connection of broken arch item
The quantity of bar is 1~10.Current feed weight is transferred to control unit in real time by weighing sensor, and control unit obtains current
Feed weight and the revolving speed for carrying out control driving device after data processing, driving device pass through shaft coupling and dispenser are driven to rotate.
Detailed description of the invention
Attached FIG. 1 is a schematic structural view of the utility model, and attached drawing 2 is the structural schematic diagram of the utility model component dispenser 4.
In figure: 1- pedestal, 2- collector, 3- feed hopper, 4- dispenser, 5- weighing sensor, 6- bracket, 7- shaft coupling,
8- driving device, 9- control unit.
Specific embodiment
Below in conjunction with attached drawing, elaborate to the utility model.As shown in Fig. 1: pedestal 1 is the base of whole device
This braced frame, collector 2 are placed on the bottom of pedestal 1, collect the powder material fallen from feed hopper 3.Control unit 9
It can independently place, can also be fixed on pedestal 1.1~8 high-precision weighing sensor 5 of top layout of pedestal 1, weighing pass
Sensor 5 it is more, precision is lower, considers from stability and accuracy synthesis, arrange 2~3 it is best.Feed hopper 3 and bracket 6 are solid
It is scheduled on weighing sensor 5, driving device 8 is fixed on 6 center of bracket, and is connect with dispenser 4 by shaft coupling 7.
As shown in Fig. 2, dispenser 4 includes the parts such as screw auger 401, shaft 402, broken arch item 403, connecting rod 404.
Broken arch item 403 can arrange 1~10, it is contemplated that stress is symmetrical and optimum efficiency, is circumferentially evenly arranged 2~4 most for 360 °
It is reasonable.Broken arch item 403 and shaft 402 are fixed by connecting rod 404, and connection sheet needed for every broken arch item 403 can be 1~
10, fixed form can be welding, riveting or fastener and fix.When 4 circular-rotation of dispenser, broken arch item 403 because with
Shaft 402 is fixed as one, so the inner wall that broken arch item also can against feed hopper 3 does circular-rotation, effectively solves powder arch camber
Problem.Screw auger 401 is coaxial fixed with shaft 402, the cylindrical discharge nozzle of screw auger 401 and 3 lower end of feed hopper vertically
Cooperation controls gap value, and when shaft 402 rotates, screw auger 401 is also being rotated, and screw auger 401 can play two at this time
A effect: first is that uniform conveying powdery material downwards；Second is that the whereabouts of limitation powder material.Powder material is contained in feed hopper 3
Interior, when driving device 8 drives dispenser 4 to rotate, powder material will uniformly be dropped into collector 2 by screw auger 401,
Due to there is powder to leave feed hopper 3, the weight value that control unit 9 obtains in real time from weighing sensor 5 will change, control unit
9 can compare according to the changing rule of weight value with preset value, then obtain the theoretical rotational speed value of driving device 8 and issue
Driving signal, to realize accurate feeding.
Driving device 8 can be realized using modes such as stepper motor, servo motor, magnetic drives, while can also be used
Speed reducer increases torque.
Control unit 9 can be using PLC or single-chip microcontroller as data processing module, using touch screen or instrument or PC conduct
Human-computer interaction interface.
By described above it is found that obtaining real-time weight value using high-precision weighing sensor 5, control unit 9 realizes number
According to processing, dispenser 4 realizes broken arch and even feeding, final to realize the continuous, uniform of powder, accurate feeding.
