Abstract
Disclosed is a pneumatic conveying installation, in particular a cut tobacco conveying installation, for conveying a material to be conveyed, in particular cut tobacco, in a gas stream, comprising a plurality of conveying lines (10, 11, 12) that are filled with material to be conveyed in the gas stream, in particular the air steam, and comprising at least one separating device (2) for each of the conveying lines (10, 11, 12). The separating device (2) is integrated into each of the conveying lines (10, 11, 12) and is designed so as to separate the material to be conveyed and to further conduct the remaining gas stream that has been substantially separated from the material to be conveyed in the conveying line. A regulation unit (31, 32, 33) is arranged downstream of each separating device (2) in the conveying line, which regulation unit comprises and regulates a throttle device so as to set a predefined conveying speed in the respective conveying line (10, 11, 12) by setting a throttle level above or equal to a predefined minimum value (Rmin), wherein the conveying installation has a common conveying device for conveying the material to be conveyed through the conveying lines (10, 11, 12). The conveying installation comprises a control and regulation device (5), which communicates with the conveying device (4) and which is designed to record the momentary throttle levels of the throttle devices and to vary the conveying power of the conveying device (4). The control and regulation device (5) is further designed to vary the conveying power of the conveying device (4) such that the throttle level of at least one throttle device lies, in each case, in the range of the minimum throttle level (Rmin).
Description
Technical field
The present invention relates to a kind of pneumatic conveying equipment as described in the preamble according to claim 1 and a kind of method for running pneumatic conveying equipment as described in the preamble according to claim 5.
Background technology
This conveying equipment is mainly for delivery of pipe tobacco.This conveying is undertaken by the compressor (especially ventilation blower) producing pressure reduction in pipe-line system being arranged on downstream in the mode of being carried by the suction of pipeline usually.In general other also can be used to be in pressure run or aspirate operating conveying device.By enter at material conveyance conduit material input part and be arranged in conveyance conduit for by the pressure reduction between conveying air and the separator that is separated of conveying material, air and therefore carry material to move in pipe-line system.Separator is carried material and air flow open.Usually, compressor is that multiple conveyance conduit produces negative pressure, and these conveyance conduits are configured to the pipeline be communicated with.Each conveyance conduit is equipped with independent regulating system at this, and this is such as known by DE 10 2,006 011 742 B1.
The task of these regulons is, considers that the parameter (as length of pipe, conveying equipment receive the mode of conveying material and the product performance of conveying material) changed all the time maintains the special regulation transporting velocity preset.Regulon produces air drag by throttling arrangement, and this air drag causes material to enter reducing for the Pressure Drop carried between the material input location of transfer pipeline and separator.Realize the expection transporting velocity of conveying air by throttling degree and therefore realize the expection transporting velocity of conveying material.
Select, with Power operation conveying device large like this, i.e. especially ventilation blower, to make the pressure reduction in pipe-line system large so all the time, so that independently maintain certain minimum delivery speed with the position of corresponding choke valve at this.Conveying device produces negative pressure usually in induction system in practice, because it is arranged on separator downstream usually.
In practice, conveying device produces the negative pressure be significantly higher than needed for induction system reality usually.Therefore, the power consumption of conveying device is than required height.
This be in many systems because conveying device completely with firm power without adjustably running.Unnecessary energy is consumed by the choke valve being arranged on pipe tobacco separator downstream usually at this.Although the power adjustable that there is its conveying device is whole or adjustable conveying equipment, but the adjusted value of the setting of the adjustment of conveying device in such devices conveying device in other words must be selected high like this, thus guarantee in the whole adjustable range of the restriction be conditioned of each conveyance conduit in systems in which without any position lower than required tobacco minimum delivery speed.This means, even if in the conveying device be conditioned, this conveying device must produce negative pressure large so all the time, so that it is all for regulating the throttling arrangement of transporting velocity independently of one another and work, and can all be not less than required minimum delivery speed on any position of conveying equipment in its whole adjusting range simultaneously.
Summary of the invention
Therefore, task of the present invention is to provide a kind of pneumatic conveying equipment and a kind of method for running pneumatic conveying equipment, by they remarkable energy ezpenditure reducing conveying device and be in operation.
This task is by having the pneumatic conveying equipment of the feature of claim 1 and having the solving for the method running pneumatic conveying equipment of feature of claim 5.Favourable embodiment provides in the dependent claims.
The present invention utilizes: can provide the information about current throttling degree on each regulon.The pressure that can change conveying device according to the present invention produces, thus can the energy ezpenditure of influential system, and described conveying device can be suction conveyer or pressure-feeding apparatus.
For regulon defines minimum throttling degree (R
min), being in operation should lower than this minimum throttling degree, because which limit each ducted maximal rate.R
mincorresponding to the maximum permission open position of the choke valve of the throttling arrangement matched.
According to the present invention, arrange now control and adjusting device, it can change the power of conveying device like this, makes at least one regulon at R
minscope in work." R
minscope " represent and like this regulate relevant choke valve, make it not open larger as far as possible.
Guarantee that conveying device only consumes required energy all the time by adjustment according to the present invention.
This such as can realize like this: the actual value such as transmitting current operating conditions, especially the throttling degree of regulon by bus system to center-control and adjusting device.Control and adjusting device in assessment report data and be conveying device determination setting.When ventilation blower is as conveying device, the rotating speed of the electro-motor driving ventilation blower can be adjusted by frequency converter.
Accompanying drawing explanation
The present invention is described in detail below by accompanying drawing.
