Description
Technical field
The present invention relates to a kind of pneumatic conveying equipment and a kind of method for running pneumatic conveying equipment.
Background technology
This conveying equipment is mainly for delivery of pipe tobacco.It is this to convey generally to borrow by way of the suction conveying of pipeline
Help and be arranged on the compressor (especially ventilation blower) of generation pressure difference in pipe-line system in downstream to carry out.In general it can also make
Operating conveying device is run or aspirated in pressure with other.By material enter conveyance conduit material input unit and
The pressure difference between air and the separator that separates of conveying material will be conveyed by being arranged on being used in conveyance conduit, air and therefore
Conveying material is moved in pipe-line system.Material is conveyed on separator to separate with air stream.Generally, compressor is multiple conveyings
Pipeline produces negative pressure, and these conveyance conduits are configured to the pipeline of connection.Each conveyance conduit is equipped with individually regulation system herein
System, this is for example as known to the B1 of DE 10 2,006 011 742.
The task of these adjustment units is, it is considered to which (such as length of pipe, conveying equipment receive conveying to the parameter changed all the time
The product performance of the mode of material and conveying material) maintain special default regulation transporting velocity.Adjustment unit is by throttling
Device produces air drag, and the air drag causes the use that material enters between the material input location and separator of transfer pipeline
Reduce in the pressure drop of conveying.The expection transporting velocity of conveying air is realized by degree of throttling and conveying material is therefore realized
It is expected that transporting velocity.
Select herein with so big Power operation conveying device, i.e. especially ventilation blower so that the pressure in pipe-line system
Difference is so big all the time, so that independently maintaining certain minimum delivery speed with the position of corresponding choke valve.Convey in practice
Device generally produces negative pressure in induction system, because it is generally arranged at separator downstream.
In practice, conveying device, which is generally produced, is significantly higher than the actually required negative pressure of induction system.Therefore, conveying device
Power consumption it is higher than required.
This be in many systems because conveying device completely with firm power without adjustably running.Unnecessary energy is herein
Generally consumed by being arranged on the choke valve of pipe tobacco separator downstream.Although whole or can in the presence of the power adjustable of its conveying device
The conveying equipment of regulation, but the adjusted value of the setting of the regulation of conveying device conveying device in other words in such devices is necessary
Select so high, so that ensuring do not have in systems in the whole adjustable range of the restriction being conditioned of each conveyance conduit
There is any position to be less than required tobacco minimum delivery speed.It means that in the conveying device being conditioned, this is defeated
Device is sent to produce so big negative pressure all the time, so that all throttling arrangements for being used to adjust transporting velocity are in its whole adjustment
Can be independently of one another while work in scope, and be all not less than on any position of conveying equipment required minimum defeated
Send speed.
The content of the invention
Therefore, task of the invention is to provide a kind of pneumatic conveying equipment and a kind of for running pneumatic conveying equipment
Method, the energy expenditure of conveying device in operation is significantly reduced by them.
The present invention is utilized：Information on current throttling degree can be provided in each adjustment unit.It can be changed according to the present invention
The pressure for becoming conveying device is produced, and so as to influence the energy expenditure of system, the conveying device can be suction conveying dress
Put or pressure-feeding apparatus.
Minimum throttling degree (R is defined for adjustment unitmin), the minimum throttling degree is not lower than in operation, therefore is limited
Maximal rate in each pipeline.RminCorresponding to the maximum allowable open position of the choke valve of the throttling arrangement of matching.
According to the present invention, control and adjusting means are set now, and it can so change the power of conveying device so that extremely
A few adjustment unit is in RminScope in work.“RminScope " represent so related choke valve of regulation so that it is use up
It may not open bigger.
By ensuring that conveying device only consumes required energy all the time according to the regulation of the present invention.
This can for example be achieved in that：For example controlled by bus system to center and adjusting means transmits working as adjustment unit
The actual value of preceding running status, especially throttling degree.In control and adjusting means the data of assessment report and for conveying dress
Put determination setting.In the case where ventilation blower is as conveying device, the electronic of driving ventilation blower can be adjusted by frequency converter
The rotating speed of motor.
Brief description of the drawings
Below the present invention is described in detail by accompanying drawing.
Embodiment
Accompanying drawing shows the significant components according to pneumatic conveying equipment of the invention, especially pipe tobacco conveying equipment with block diagram.
Provided with multiple conveyance conduits 10,11,12, they are supplied conveying material in feeding area 1 respectively.In delivery pipe
Separator 2 is integrated with road 10,11,12, these separators will convey material, especially pipe tobacco and be separated with conveying air.
In order to produce pressure drop, one common compressor (being referred to generically as conveying device) 4 is set in the downstream of conveyance conduit 10,11,12.Institute
Showing that equipment is configured to aspirate conveying equipment, but being arranged on the pressure conveyor of the upstream of separator 2 can also work according to the present invention.
One adjustment unit 31,32,33 is set respectively in these downstreams of separator 2, and the adjustment unit regulation is not (detailed
Carefully show) there is the throttling arrangement of choke valve.Therefore, it can provide and can be read on phase in adjustment unit 31,32,33
Answer open position, the information of i.e. corresponding throttling degree of choke valve.Described information can be transmitted to via the interface of matching control and
Adjusting means 5, the interface is shown as signal wire 315,325,335 herein, but also can wirelessly work.Control and regulation
Device 5 compares the throttling degree and (may be respectively) default minimum throttling degree R of each adjustment unit 31,32,33min.Change now
The power consumption of conveying device 4, until the current throttling degree of one (at least) throttling arrangement is in RminScope in.In the model
It is meant that so adjusting throttling degree by changing the power consumption of conveying device 4 by control and adjusting means 5 in enclosing, make
