Detailed description of the invention
Fig. 1 is the schematic diagram of sludge transport control system provided by the embodiment of the present invention.
Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with specific embodiment, and reference
Attached drawing, the present invention is described in further detail.
As shown in Figure 1, a kind of sludge transport control system, including sequentially connected belt feeder 1, bucket elevator 2 and pipe conveyer
3, sludge is elevated into bucket elevator 2 along belt feeder 1 and enters pipe conveyer 3, and moves from system along pipe conveyer 3；The pipe
The position of feeding end is provided with the first Weighing module 31, belt feeder 1, bucket elevator 2, the motor of pipe conveyer 3 and first with machine 3
Weighing module 31 is electrically connected with a control module 4 respectively；The pan feeding situation of pipe conveyer 3 is obtained by the first Weighing module 31, such as
When fruit discovery charging is excessive, pipe conveyer 3 is controlled by control module 4 in time and is accelerated, and reduces its front end belt feeder 1 and bucket
The working frequency of machine 2 is proposed, to prevent sludge blockage；When the inlet amount of pipe conveyer 3 is lower, in order to improve working efficiency, control
Molding block 4, which issues order, reduces the working frequency of pipe conveyer 3, while the work of its front end belt feeder 1 and bucket elevator 2 can be improved
Frequency, to make the basic full-load run of pipe conveyer 3.
In order to more accurately understand material operating condition, the operating condition of each component of more precise control, the belt feeder 1
One end close to bucket elevator is additionally provided with the second Weighing module 11, and the second Weighing module 11 is also electrically connected with control module 4.
The invention also discloses the control methods of sludge transport control system, comprising the following steps:
It is the setting delivery conveying of pipe conveyer 3 section by control module 4；
The numerical value for obtaining the first Weighing module 31 obtains 3 delivery value of pipe conveyer；It is compared with delivery conveying section；
If delivery value is more than the conveying section upper limit, 3 speed of service of pipe conveyer is improved, pipe conveyer 3 is otherwise reduced and runs speed
Degree.
Specific control process is as follows:
User is that a conveying optimum value v in conveying section is arranged in pipe conveyer 30, as delivery value vtMore than delivery area
Between the upper limit when, then the adjusted value Δ v of conveying capacity are as follows:
Wherein, v is present speed, and present speed is increased Δ v in 10~60s.
As delivery value vtWhen lower than conveying interval limit, the adjusted value Δ v of conveying capacity are as follows:
Present speed is reduced into Δ v in 30~120s.
In actual use, determine that conveying capacity, speed and frequency can consider in just generally by the frequency of motor
Than variation, therefore, the parameter in formula above is revised as corresponding frequency.
In preferred embodiment, also by introducing the numerical value of the second Weighing module 11, whole system is more accurately controlled
System, the specific method is as follows:
It is the setting carrying range of bucket elevator 3 by control module 4；
The difference for calculating the integral of the weighing value of the second Weighing module 11 and the first Weighing module 31, works as bucket elevator 2
The actual bearer value at preceding moment；
According to the relationship of actual bearer value and carrying range, working method is adjusted, specific as follows:
Situation A: when actual bearer value determines range less than load, control module 4 reduces the motor working frequency of pipe conveyer 3, together
The working frequency of Shi Tigao bucket elevator 2；Material at this time in bucket elevator 2 is less, is rapidly entered in pipe conveyer 3 by things material,
Pipe conveyer 3 can be allowed to keep higher delivery horizontal, improve working efficiency.
Situation B: when actual bearer value determines range greater than load, control module 4 improves the working frequency of pipe conveyer 3, drops simultaneously
The working frequency of low bucket elevator 2；Material at this time in bucket elevator 2 is more, by improving the speed of pipe conveyer 3, reduces bucket elevator 2
Blanking amount, guarantee will not occur block tube expansion.
Particular embodiments described above has carried out further in detail the purpose of the present invention, technical scheme and beneficial effects
It describes in detail bright, it should be understood that the above is only a specific embodiment of the present invention, is not intended to restrict the invention, not
It is any modification that those of ordinary skill in the art make the present invention, equivalent under the premise of being detached from the spirit and principles in the present invention
Replacement, improvement etc., should all fall within the protection scope that claims of the present invention determines.
