The specific embodiment
Below in conjunction with accompanying drawing, the technical scheme in the utility model is clearly and completely described.
The utility model comprises at least two-stage pneumatic separator, embodiment illustrated in fig. 1ly as an example of two-stage pneumatic separator example, describes.The utility model also comprises the front electronic scale 12 of baking that is located at first order pneumatic separator front end, be located at the electronic platform scale 8 at the feeder place of afterbody pneumatic separator, PLC controller 11, and be arranged on angle actuator (the first jiao of actuator 13 on the return air duct of every grade of pneumatic separator, second jiao of actuator 14), before drying, electronic scale 12 is for being metered into the pipe tobacco cumulative amount of pneumatic separator, electronic platform scale 8 is for measuring the stalk label weight of rejecting, before drying, the signal output part of electronic scale 12 and electronic platform scale 8 is connected with PLC controller 11, the angle actuator (13 of PLC controller 11 and every grade of pneumatic separator, 14) connect.
As shown in Figure 2, place pulp-collecting box 6 on electronic platform scale 8, pulp-collecting box 6 is limited to the Weighing Area of electronic platform scale 8 by fixed support 7.The exit of afterbody Winnowing box is provided with for the closing in 5 to pulp-collecting box 6 by the stalk label centralized collection of rejecting.
The working method of multistage pneumatic separation system is to produce negative pressure exhausting by blower fan, through deduster, by tiny filtrating smoke dust, angle actuator is installed on return air duct for controlling return air size, and then affects the vacuum magnitude in Winnowing box.Stalk label and foreign material heavier in Winnowing box can drop in pulp-collecting box, normal pipe tobacco can be siphoned away by negative pressure, in feeder, isolate, through the discharging groove that shakes, be transported to next link, multistage pneumatic separation by 2 times or repeatedly selection by winnowing reach and improve stalk and sign and the object of foreign material rejecting rate, the utility model is to describe as an example of two-stage pneumatic separator example.
Please refer to Fig. 2, the pipe tobacco of rejecting out from selection by winnowing and stalk are signed by the charging groove 1 that shakes and are sent into secondary Winnowing box 2(afterbody selection by winnowing), material is being dredged under the effect of roll dies 9 up and down, in selection by winnowing and conveying process, the pipe tobacco of conglomeration is broken up, lighter qualified pipe tobacco is seen off by wind, and heavier stalk label and foreign material fall.The effect of adjustable plate 3 is to regulate intake and guide functions, once lock no longer manual adjustment by fixed screw after mixing up.The filter screen cover 4 of becalming adopts stainless steel filtering nets to make, and when being arranged in this and preventing air intake, in air, subsidiary foreign material are inhaled into.Close up 5 for by reject stalk label centralized collection to pulp-collecting box 6, prevent stalk sign fall outside box, impact weigh accuracy.Fixed support 7 is limited to the position of pulp-collecting box 6 Weighing Area of electronic platform scale, prevents because pulp-collecting box 6 placement locations are not inaccurate to the weighing causing.Electronic platform scale 8 is for high-precision electronic scale is for weighing rejecting stalk label weight out.The present embodiment electronic platform scale 8, for guaranteeing stability and the accuracy of data communication, adopts the PROFIBUS-DP bus of Siemens, and high accuracy is guaranteed like this.When occurring in system that data transmission exception or pulp-collecting box completely etc. are reported to the police, warning is sent in audible-visual annunciator 10 actions, and alert is processed.
The utility model increases electronic platform scale 8(by the end one-level selection by winnowing feeder place (being the place of the final discharging of foreign material) and requires and every batch of maximum blanking amount according to the control accuracy of system, the weighing precision of selected this electronic platform scale 8 is 0.002KG, range is 200KG), and in conjunction with electronic scale 12 before the baking before selection by winnowing operation, can calculate the pipe tobacco cumulative amount through aidr bells blast system through time delay, by the pipe tobacco cumulative amount through selection by winnowing, can obtain theoretical eliminating stems label amount, to by network, pass in PLC controller 11 through the stalk label weight of electronic scale collection, in PLC program, comparison of design revision program changes the wind speed of current blast system, changing wind speed is to realize by the angle actuator of adjustment return air duct, and then automatically control material separating amount.
As described in Figure 2, arranging that electronic platform scale 8 gathers after the stalk label weight of rejecting, by increasing feedback closed loop link and designing control algolithm, make original manual control system become automatic control system, concrete, please refer to Fig. 3, before drying, electronic scale 12 can calculate the pipe tobacco cumulative amount T through aidr bells blast system through time delay, electronic platform scale 8 can measure the stalk label weight W of rejecting, suppose that it is p that stalk is signed rejecting preset proportion, stalk is signed and rejected difference is f, main air intake aperture is K1, secondary air register aperture is K2, if there is f=W-T*p f>0, secondary air register aperture K2+0.5, if f<0, secondary air register K2-0.5, main air intake K1+0.5 of f>0 when in continuous two comparisons, main air intake K2-0.5 of f<0 when in continuous two comparisons.PLC controller sends to corresponding first jiao of actuator 13 or second jiao of actuator 14 by the aperture signal calculating, and regulates the aperture of opening air door, with the stalk label rejecting amount to every grade of pneumatic separator, regulates.
Please refer to Fig. 3, the utility model also comprises the audible-visual annunciator 10 and the man-machine interface 15 that are connected with PLC controller 11, described man-machine interface 15 can be used for the parameter of input setting and carries out the demonstration of relevant parameter, and for example input stalk is signed rejecting preset proportion, carried out the real-time demonstration of current eliminating stems label weight etc.
The utility model has been realized after closed-loop control system, by the stalk label actual weight of rejecting, system is carried out approximately 20 contrasts uniformly, and manual adjustment before this has the uncertainty of randomness and adjusting, and the number of times of manual adjustment is less, in so just having solved batch, the artificial index stalk label up to standard and that cause of pursuing are rejected unevenly, greatly improve the promptness regulating, and do not need manually stalk to be signed to weigh, this proofreaies and correct concerning important rejecting in time.The weight of material of rejecting by increase detects closed loop; when the stalk label of rejecting are more or less, electronic platform scale 8 can detect automatically; for example, when the weight (that is electronic platform scale 8 is exported to the numerical value of PLC controller 11) of the stalk label box under secondary selection by winnowing exceedes 23KG; PLC controller 11 is controlled audible-visual annunciator 10 and is sent sound and light alarm signal and change box with prompting; preventing that stalk from signing overflows, and therefore not only can automatic decision go out extremely can also be to processing extremely for system.
The utility model has been realized stalk and has been signed the Whole Process Control of rejecting, make operative employee's adjusting and monitoring have reference value, and pass through automation control system, reduced operating personnel's working strength, improved the accuracy that system is regulated, by effect, confirm (in Table 1), every batch of the stalk label amount eliminating now all can be up to standard, and this value was unsettled before this project implementation.
