In order to make the technical solution and advantages of the present invention more prominent, the following system structure is combined to make an exemplary description of the operation process of the present invention.
First, the ratio of each component material is determined according to the composition of the target coating liquid. Under the condition of using the upper computer, the process formula proportion of each component feed liquid of the coating liquid is allowed to be added, modified and deleted in a control interface of the upper computer shown in figure 2, and the edited and confirmed process formula can be stored in the upper computer, or the existing process formula in the upper computer can be directly called for use, or a new process formula is generated after editing on the basis of the existing process formula;
the amounts of each ingredient feed solution were then calculated. For example, in the interface shown in fig. 3, the amount of each ingredient (ingredient liquid, concentrate, etc.) can be calculated by two calculation modes. The first mode is as follows: the total amount of the concentrated solution is taken as a reference, the absolute amount of other feed liquid with each component can be calculated one by one according to the process formula, meanwhile, the total amount of the coating liquid under the process formula can be calculated, if the total amount exceeds the maximum allowable amount of the blending tank body, the system automatically prompts an alarm, the formula example cannot be realized, and the resetting generation is required; model two: and (3) calculating the absolute quantity of each component material liquid one by one according to a process formula by taking the total amount of the coating liquid of the final formula example as a reference, and if the total amount of the input coating liquid exceeds the maximum allowable amount of the preparation tank, automatically prompting an alarm by a system, wherein the formula example cannot be realized and requires resetting generation.
Of course, it should be specifically noted that the process of calculating the amount of each ingredient may be performed manually, but is preferably performed automatically by a controller such as an upper computer.
Then, the ingredient liquid is added in the calculated amount. For example, in the interface shown in fig. 4, when the blending mode is selected as "combination" and the control circuit for each component liquid is "automatic", the system sets the addition amount of each component liquid to the control target as the set value confirmed in the previous step. Clicking the 'feeding start' of the first ingredient liquid can start automatic feeding and blending. The process is that the switch valve of the connecting pipeline from the component feed liquid storage tank/component material liquid preparation tank/concentrated liquid storage tank to be added to the preparation tank is opened, and the conveying pump on the corresponding pipeline is started. When the difference value between the current weight of the blending tank which is collected and monitored in real time and the weight of the ingredient material liquid before adding is close to the 'feeding amount set value', the delivery pump and the switch valve on the corresponding connecting pipeline are closed in advance. It should be noted that, because the lengths of the connecting pipelines from each component material liquid tank body to the blending tank are different, the difference coefficients of the advanced closing in the above processes are different, and the difference coefficients are determined according to the actual process after debugging. After a plurality of tests, the inventor finally controls the blending deviation within +/-2.0 kg. After the addition of the individual component feed liquid is finished, residual feed liquid in the pipeline needs to be blown back, the system opens the blow-back valve after the addition of the component feed liquid is finished, and closes the corresponding valve on the blow-back pipeline after the blow-back is finished according to the set time. And in the automatic allocation process, when the feeding is required to be suspended, the conveying pump is immediately closed, and the operation is started again when the feeding is resumed. Or in the suspension process, the automatic blending process can be directly manually completed, the system closes the pipeline valve, marks the state of the automatic blending process as 'end', and clears the set values of the feed liquid of each component. Under the condition of adopting the upper computer, the current states of the system, namely feeding preparation, feeding starting, feeding ending and feeding accumulated value, can be monitored in real time through a monitoring picture of the upper computer. Meanwhile, in order to flexibly adapt to different working conditions, the system can operate in a stand-alone mode or a manual mode. The 'single machine' mode is that each ingredient liquid is respectively blended without forming linkage with other ingredient liquids, and can be divided into a 'manual' mode and an 'automatic' mode under the mode. The manual mode is completely controlled by manual operation to start and end the feed liquid adding. In the automatic mode, the system automatically opens a switch valve on a connecting pipeline and starts a delivery pump according to an input 'feeding amount setting' value, and the system automatically stops when the 'feeding accumulated value' reaches a set value. Of course, the specific charging process may be controlled manually by the operator according to the calculated value, and this embodiment is not limited strictly.
The temperature control process of the coating liquid is shown in fig. 5. The temperature of the coating liquid in the on-site tank and the temperature of the heat preservation device form cascade control, wherein the temperature of the coating liquid is an outer ring control object, and a heat exchange medium (such as circulating water) of the heat preservation device is an inner ring control object. In the inner ring of cascade control, when the deviation of the heat exchange medium is greater than the control dead zone, the controller takes the temperature deviation as the input quantity to control and regulate the regulating valve of the heat exchanger. In an outer ring of cascade control, when the deviation of the temperature of the coating liquid is greater than the control dead zone, the temperature deviation is used as an input quantity by a coating liquid temperature controller, and the set temperature of the heat exchange medium is obtained after calculation and conversion by the controller; otherwise, no control adjustment is made. When the temperature of the heat exchange medium is stable, the temperature of the coating liquid is controlled and regulated through the screw pump delivery of the heat exchange medium. In the actual working process, under the condition that the temperature of the in-situ tank heat exchange medium is stable, when the system monitors that the temperature of the coating liquid in the in-situ tank is about to be lower than the set range of the process (advance action), the conveying pump is started to convey heat so that the temperature of the coating liquid in the in-situ tank is gradually increased, and when the temperature of the coating liquid in the in-situ tank is about to reach the upper limit of the set range of the process (advance action), the conveying. The process temperature and the temperature error range of the coating liquid in the in-situ tank of different coating liquids can be set by an operator on the picture of an upper computer. In order to prevent the temperature of the in-situ tank from being obviously reduced due to the intermittent replenishment of the fresh coating liquid, the adding flow rates of the fresh coating liquid and the recovered coating liquid can be continuously adjusted and controlled, so that the two coating liquids can continuously enter the in-situ tank. The system monitors the flow transmitted from the recovery tank to the local tank, controls the regulating valve from the blending tank to the local tank, and always keeps the flow of the fresh coating liquid entering the local tank and the flow of the recovered coating liquid stable. For example, as shown in fig. 6, a flow set value of the recovered coating liquid is set according to the flow requirement of the coating liquid in the coating process, and the consumption of the coating liquid per unit time is calculated according to the coating rate required by the process, so as to obtain the replenishment flow of the fresh coating liquid, that is, the flow set value of the fresh coating liquid. The flow rate of the coating liquid is respectively taken as a control object, and the flow rate of the coating liquid added into the in-situ tank is controlled by adjusting the frequency of the delivery pump or the opening degree of the switch valve. Under the control mode, the system automatically monitors the liquid level of the current coating liquid in-situ tank in real time, so that the liquid level is always between the lowest liquid level and the highest liquid level, and the liquid level is kept basically stable, thereby meeting the control requirement of continuously supplying liquid for the coating machine stably.
Referring to fig. 1, the present invention further provides a reconstituted tobacco coating liquid coating system, which comprises a coating device, a recovery tank and the reconstituted tobacco coating liquid automatic blending system according to any one of the above schemes, wherein the in-situ tank is connected to the coating device, and the recovery tank is connected to the coating device and the in-situ tank.
