Specific embodiment
In order to make those skilled in the art better understand the technical solutions in the application, below in conjunction with attached drawing, it is right
Technical solution in the embodiment of the present application is clearly and completely described.
As shown in Figure 1, the embodiment of the present application one provides a kind of vibrating sieving machine screening end-point control method, the method includes such as
Lower step:
In step s101, after vibrating sieving machine starting, the screening state of the vibrating sieving machine is obtained.
Screening state described here includes sufficiently screening and sufficiently screening, is going out according to the sieves at different levels of vibrating sieving machine
Situation is expected to determine, for example certain vibrating sieving machine from top to bottom includes 4 layers of sieve, sets gradually grade 5mm, 3mm, 1mm and 0.5mm tetra-
Layer sieve pore, material enter first order sieve from vibrating sieving machine top feed mouth, filter out the material that granularity is greater than 5mm, and granularity is less than
Or be equal to and enter second level sieve, filter out granularity in the material of 3mm-5mm, and so on, material successively passes through sieves at different levels,
To screen out five kinds of different grain sizes composition less than 0.5mm, 0.5mm-1mm, 1mm-3mm, 3mm-5mm and greater than 5mm.?
In the vibrating sieving machine course of work, if 4 layers of sieve pass through without material, then it is assumed that five kinds of granularmetric compositions are screened to be finished, vibration
Screen(ing) machine is sufficiently to sieve state;If at least one sieve is also discharging, then screening process is not in 4 layers of sieve, vibration
Screen(ing) machine is not sieve state sufficiently, and vibrating sieving machine is needed to work on.
Further, in step s101, the screening state of the vibrating sieving machine is obtained according to the following steps:
Corresponding stream sensor is set on the sieves at different levels of the vibrating sieving machine;
Passing through mass flow S1, S2 ... the Sn, n of the sieves at different levels of vibrating sieving machine by stream sensor detection is vibrating sieving machine
Sieve quantity;
According to mass flow S1, S2 ... Sn of the sieves at different levels of the vibrating sieving machine, the screening state of the vibrating sieving machine is obtained,
The screening state includes sufficiently screening and not sufficiently screening.
The stream sensor is used to detect the load of the mass flow namely sieve at different levels by sieves at different levels, material
The preferred photoelectric sensor of flow sensor or laser sensor, consequently facilitating measurement passes through the mass flow of vibrating sieving machine sieves at different levels,
Detection efficiency is improved, can also choose other kinds of sensor according to actual needs, the application is not construed as limiting this.It is burnt in evaluation
When tying mix size, it is assumed that certain vibrating sieving machine has 4 layers of sieve, then every layer of sieve requires that corresponding stream sensor is arranged,
Respectively MS1, MS2, MS3 and MS4, MS1 detection are sieved by mass flow S1, the MS2 detection of first order sieve by the second level
Mass flow S2, the MS3 detection of son pass through the material of fourth stage sieve by mass flow S3, the MS4 detection of third level sieve
Flow S4 carries out comprehensive judgement by the testing result to S1, S2, S3 and S4, to obtain the screening state of vibrating sieving machine.Stream passes
Sensor is mountable on sieve, may also be arranged on the support rod beside sieve.
In step s 102, according to the screening state of the vibrating sieving machine, judge whether to meet timing condition;
Further, judge whether to meet timing condition according to the following steps:
If mass flow S1, S2 ... Sn of the sieves at different levels by vibrating sieving machine are zero, it is determined that the vibration sieve
The screening state of machine is sufficiently screening, meets timing condition;
If at least one numerical value is greater than in mass flow S1, S2 ... Sn of the sieves at different levels by vibrating sieving machine
Zero, it is determined that the screening state of the vibrating sieving machine is not sufficiently screening, is unsatisfactory for timing condition.
Assuming that the testing result of each stream sensor is S1=0, S2=0, S3=0, S4=0 at current time, knot is determined
Fruit is that vibrating sieving machine is in sufficiently screening state, however, in time after current time, it is possible to there are also material pass through it is a certain
Sieve, so that the testing result Si ﹥ 0 of its corresponding stream sensor, i.e. the screening state of vibrating sieving machine is changed, by abundant
Screening variation is inabundant screening state, stops screening machine if at the current time, and material is not sieved sufficiently,
Subsequent size composition testing result is caused error occur, therefore, to guarantee that vibrating sieving machine sufficiently sieves material, while again not
The case where will appear sieving, the application continue step with the following method.
In step s 103, if meeting timing condition, start timer.
In step S104, during the timer reaches preset time T, if the screening shape of the vibrating sieving machine
Remaining unchanged of state stops the vibrating sieving machine then when the timer reaches preset time T.
In mass flow S1, S2 ... Sn by the sieves at different levels of vibrating sieving machine, at least one numerical value is greater than zero, then shakes
The screening state of screen(ing) machine is not sufficiently screening, is unsatisfactory for timing condition, timer does not start;And if only if each by vibrating sieving machine
When mass flow S1, S2 ... Sn of grade sieve are zero, it is believed that vibrating sieving machine is in sufficiently screening state, meets timing condition, this
Shi Qidong timer, judges in preset time T, and whether vibrating sieving machine remains abundant screening state, if vibrating sieving machine is at this
Remain that abundant screening state is constant in the section time, then it is believed that the indeed abundant screening materials carrying of vibrating sieving machine, to avoid being sieved,
It needs to control screening process in time and reaches terminal, stop vibrating sieving machine work, terminate screening.
If preset time T is too short, material may not sieved sufficiently, and if preset time T is too long, it also results in
Sieving, additionally increases energy consumption, therefore, in the present embodiment, preset time T is preferably 5 seconds.
As it can be seen that it is each that the application can obtain in real time screening process compared to the existing method for setting fixed sieving time
The variation of grade flow, the accurate screening terminal for automatically controlling vibrating sieving machine had both ensured that vibrating sieving machine carried out sufficient grade to material
Screening, and can prevent from being sieved, to effectively improve the working efficiency of material grade screening, and reduce the energy consumption of vibrating sieving machine.
As shown in Fig. 2, the present embodiment also provides another vibrating sieving machine screening end-point control method, due to mixed in evaluation sintering
When closing material granularity, tetra- layers of sieve pore of grade 0.5mm, 1mm, 3mm, 5mm are usually set, and therefore, this says for sentencing sieve quantity 4
Bright, the quantity of corresponding stream sensor is also 4, and detection data is respectively S1, S2, S3 and S4.
In step s 201, detection data S1, S2, S3 and S4 of each stream sensor are obtained.This data acquisition
It is real-time, and the detection process of Material Sensor continues to screening terminal, to guarantee the accurate control of screening terminal.
In step S202, judge whether S1, S2, S3 and S4 are zero.If it is judged that be it is yes, then meet timing item
Part executes step S203, conversely, then continuing to execute step S201.
In step S203, timer starts timing.
In step S204, after timer initiation, judge whether at least one is greater than zero by S1, S2, S3 and S4.If sentenced
Disconnected result is yes, execution step S205, conversely, thening follow the steps S206.
In step S205, timer is reset.Since after starting timer, the screening state of vibrating sieving machine changes,
Illustrate that material is not yet sufficiently sieved, then timer be zeroed out processing at this time, timer is made to restart timing, then after
It is continuous to execute step S203 and its subsequent step.In other words, after starting the timer, once the screening state of vibrating sieving machine becomes
Change, it is necessary to reset reclocking, until vibrating sieving machine screening state continue preset time T without variation, just can be in timing
After device reaches preset time T, terminate the screening work of vibrating sieving machine.
In step S206, judge whether timer registration is greater than or equal to preset time T.If it is judged that be it is yes,
Step S207 is executed, conversely, then continuing to execute step S204.
In step S207, stop vibrating sieving machine, screening terminates.
In the present embodiment, step S204 judging result be it is no, i.e., when S1, S2, S3 and S4 are zero, execute step S206,
In period i.e. in starting timer to preset time T, need to continue to judge whether S1, S2, S3 and S4 are zero, if
In the period, S1, S2, S3 and S4 be zero state continue it is constant, then when timer reaches preset time T, execute step
Rapid S207, stops vibrating sieving machine, and screening process is reached home.The present embodiment shows step S204 and step S206 according to successive
Sequence execute, actually control in, step S204 and step S206 parallel form also can be used, as long as guarantee S1, S2, S3 and
S4 is zero, and timer registration is more than or equal to preset time T and meets simultaneously, then when timer reaches preset time T i.e.
For the screening terminal of vibrating sieving machine, to not only guarantee sufficiently to sieve, but also it is avoided that sieving, realizes the exact automatic control of screening terminal
System, improves the working efficiency of material grade screening, and reduces the energy consumption of vibrating sieving machine.
