[0015] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0019] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0020] Papermaking retention aid is a water-soluble branched organic polymer. Its function is to increase the retention rate of pulp when it is put on the screen. It has excellent retention effect on fine fibers and fillers (calcium carbonate, titanium dioxide and kaolin, etc.), and it can significantly save pulp. It is used with filter aids to enhance water filterability and reduce dehydration energy consumption in the forming, pressing and drying processes, thereby increasing paper production, reducing energy consumption and reducing costs. At the same time, it also has the function of increasing the strength of wet and dry paper, maintaining the stability of wet chemical conditions, improving paper uniformity and physical properties, and reducing the load of wastewater treatment due to the reduction of fine fibers and fillers in the effluent.

[0021] However, currently, the addition of chemical retention aids is manually controlled on-site by staff, and the amount of each layer is manually controlled. It cannot be added accurately according to the needs of the slurry, making the control of the amount of retention aid added to the slurry very inaccurate. When the retention aid is added in excess, the pulp fibers may form large flocs, and the flocs themselves have strong water retention, which may affect dehydration at the least and cause paper breaks at the worst. When the retention aid is added too little, the specific surface area of ​​the paper material as a whole becomes smaller, affecting the quality of the final paper.

[0022] In order to overcome the above problems, an exemplary embodiment of the present application provides an additive dosing system, which controls the flow rate of the additive by setting an additive control pipeline, thereby achieving control of the amount of additive added in each layer to improve the overall performance of the prepared paper.

[0023] Figure 1 The schematic diagram of the structure of an additive dosing system provided by the exemplary embodiment of the present application is shown. Figure 1 As shown, the additive dosing system 100 provided by the present application includes: at least one additive storage tank 110, at least one group of additive control pipelines 120, a controller 130 and at least one slurry storage tank 140. It should be understood that the additives involved in the exemplary embodiment of the present application can be various additives used in the papermaking process. For example, the additive can be a retention aid or a drainage aid, etc., but is not limited thereto. By reasonably controlling the amount of additive used in each layer, the overall performance of the prepared paper can be improved.

[0024] Exemplarily, the controller may be an integrated circuit including a microcontroller (MCU). The microcontroller may include a central processing unit (CPU), a read-only memory module (ROM), a random access memory module (RAM), a timing module, a digital analog conversion module (A / D Converter), and a number of input / output ports. Of course, the controller may also be an integrated circuit in other forms, such as an application-specific integrated circuit (ASIC) or a field-programmable gate array (FPGA).

[0025] like Figure 1 As shown, the inlet of each group of additive control pipelines 120 is respectively connected to each additive storage tank 110 , and the outlet of each group of additive control pipelines 120 is respectively connected to the corresponding slurry storage tank 140 .

[0026] Exemplarily, when the number of the above-mentioned additive storage tank is 1, the additive storage tank can be used to store retention aids, the number of additive control pipelines can be 3 groups, the inlet of each group of additive control pipelines is connected to the retention agent storage tank, and the outlet of each group of additive control pipelines is respectively connected to the corresponding slurry storage tank. It should be understood that in the papermaking process, the slurry before papermaking can be divided into surface slurry, core slurry and bottom slurry. Therefore, the correspondence here can be to connect the outlet of each group of additive control pipelines to the surface slurry storage tank, the core slurry storage tank and the bottom slurry storage tank respectively, so as to realize the control of the flow rate of the additives added to the surface slurry storage tank, the core slurry storage tank and the bottom slurry storage tank.

[0027] like Figure 1 As shown, each group of additive control pipelines 120 includes: a pump 121 and an additive flow control assembly 122, the inlet of the pump 121 is connected to the outlet of each additive storage tank 110, the outlet of the pump 121 is connected to the inlet of the additive flow control assembly 122, and the outlet of the additive flow control assembly 122 is connected to the corresponding slurry storage tank 140. It should be understood that when the number of additive storage tanks 110 is one, the pump 121 included in each group of additive control pipelines 120 is connected to the additive storage tank 110; and when the number of additive storage tanks 110 is multiple, the pump 121 included in each group of additive control pipelines 120 can be connected to the outlet of each additive storage tank 110 respectively. For the additive flow control component 122, the correspondence here can be understood as when the number of slurry storage tanks 140 is 1, the number of additive control pipelines 120 is 1 group. At this time, the outlet of the additive flow control component 122 is connected to the slurry storage tank 140; and when the number of slurry storage tanks 140 is multiple, the number of additive control pipelines 120 is also multiple groups. In this case, each group of additive control pipelines 120 is connected to one of the multiple slurry storage tanks 140 for conveying additives into the slurry storage tank 140, and the outlet of the additive flow control component 122 included in the additive control pipeline 120 is connected to the slurry storage tank 140.

[0028] like Figure 1 As shown, the controller 130 is respectively connected to the pump 121 and the additive flow control assembly 122 included in each group of additive control pipelines 120 to achieve precise control of the amount of additive added.

[0029] In practical applications, when it is necessary to deliver additives to the slurry storage tank, the controller can be used to control the opening of the pump included in the additive control pipeline corresponding to the slurry storage tank to which the additive needs to be delivered, so as to extract the additive in the additive storage tank connected to the inlet of the pump from the additive storage, and deliver it into the slurry storage tank through the additive control pipeline. At this time, the additive flow control component included in the additive control pipeline is used to detect the flow information of the additive in the additive control pipeline and send the flow information to the controller. It should be understood that before this, the controller has stored the quality information of the slurry in the slurry storage tank, so the controller has determined the flow range of the additive required in the slurry storage tank. In this case, the controller can determine whether the flow of the additive in the additive control pipeline meets the flow range of the additive required in the slurry storage tank based on the flow information sent by the additive flow control component. If not, the controller controls the additive flow control component to adjust the flow of the additive in the additive control pipeline. If it is satisfied, the monitoring can continue.

[0030] It can be seen that in the additive dosing system provided by the present application, an additive control pipeline is set between the additive storage tank and the slurry storage tank, and the additive control pipeline includes a pump and an additive flow control component, the inlet of the pump is connected to the outlet of each additive storage tank, the outlet of the pump is connected to the inlet of the additive flow control component, and the outlet of the additive flow control component is connected to the corresponding slurry storage tank. The controller is respectively communicated with the pump and the additive flow control component included in each group of additive control pipelines, so that when additives need to be added to the slurry storage tank, the pump can be controlled to open by the controller to extract the additives from the additive storage tank, and the additive flow control component is controlled by the controller to detect the flow of the additive added to the slurry storage tank and send it to the controller, and the controller controls the remaining amount of the additive added to the slurry storage tank according to the quality of the slurry in the corresponding slurry storage tank, thereby realizing reasonable control of the additives to improve the comprehensive performance of the prepared paper. At the same time, it avoids the occurrence of unsafe accidents caused by manual addition and reduces labor costs.

[0031] As a possible implementation, Figure 1As shown, the additive flow control assembly 122 includes an additive flow detector 1221 and an additive flow control valve 1222, the outlet of the pump 121 is connected to the inlet of the additive flow detector 1221, the outlet of the additive flow detector 1221 is connected to the inlet of the additive flow control valve 1222, the outlet of the additive flow control valve 1222 is connected to the corresponding slurry storage tank 140, and the additive flow detector 1221 and the additive flow control valve 1222 are respectively connected to the controller 130. It should be understood that all components involved in the exemplary embodiment of the present application are commercially available products, and all commercially available products that can meet the relevant functions of the present application are within the optional scope of the present application. The additive flow detector 1221 can be a flow sensor, and the additive flow detector 1221 and the additive flow control valve 1222 are respectively controlled by communication with the controller 130 to achieve precise control of the amount of additive added, thereby achieving control of the quality of the prepared paper, and the above control method can avoid manual addition by the staff, reduce safety risks, and reduce labor costs.

[0032] In actual applications, the additive flow detector and the additive flow control valve are respectively connected to the controller, and the additive flow detector is located between the pump and the additive flow control valve, so that when the controller controls the pump to turn on, the additive in the additive storage tank is pumped into the additive control pipeline. At this time, the additive flow detector detects the additive flow information in the additive control pipeline and sends the additive flow information to the controller, which determines whether the additive flow control valve needs to work based on the received additive flow information.

[0033] As a possible implementation, Figure 1 As shown, the additive dosing system 100 further includes at least one additive control valve 150, each of which is located at the outlet of the corresponding additive storage tank 110 and is in communication connection with the controller 130. When there are multiple additive storage tanks 110, the additive control valve 150 at the additive storage tank 110 corresponding to the additive to be added to the slurry storage tank 140 can be controlled by the additive control valve 150 to be in an open state, while the other additive control valves 150 are in a closed state, so as to achieve the switching of different additives. It should be understood that the number of additive control valves 150 here can correspond to the number of additive storage tanks 110. For example, when the number of additive storage tanks 110 is 1, the number of additive control valves 150 is 1; when the number of additive storage tanks 110 is 2, the number of additive control valves 150 is 2, etc., and it is not limited thereto.

[0034] Exemplarily, when there are multiple additive storage tanks, an additive control valve is provided at the outlet of each additive storage tank to control the opening and closing of different additive storage tanks. When a retention agent among multiple additives needs to be added to the slurry storage tank, the controller can control the control valve at the outlet of the retention agent storage tank to be in an open state, and the additive control valves of other additive storage tanks to be in a closed state, and then the controller controls the pump included in the additive control pipeline to work, and pump the retention agent in the retention agent storage tank into the corresponding slurry storage tank. When the papermaking process is ended or paused, the controller can sequentially control the pump and the additive control valve at the outlet of the retention agent storage tank to be in a closed state to stop adding the retention agent to the slurry storage tank.

[0035] Since the flow rate of the additive added to the slurry storage tank needs to be determined according to the quality of the slurry in the slurry storage tank, and during the entire papermaking process, the slurry in each slurry storage tank is in a state of circulating flow, therefore, in order to achieve precise control of the additive and improve the overall performance of the prepared paper, a slurry flow control component is provided at the slurry inlet and / or slurry outlet of the slurry storage tank. The slurry flow control component is communicatively connected to the controller and is used to ensure that the quality of the slurry in the corresponding slurry storage tank is in a stable state under the control of the controller.

[0036] The above-mentioned slurry flow control component includes a slurry flow detector and a slurry flow control valve, wherein the outlet of the slurry flow detector is connected to the inlet of the slurry flow control valve, the outlet of the slurry flow control valve is connected to the corresponding slurry storage tank, and the slurry flow detector and the slurry flow control valve are respectively connected to the controller.

[0037] Exemplarily, the slurry flow control assembly can be located at the slurry inlet of the slurry storage tank, or at the slurry outlet of the slurry storage tank, or at both the slurry inlet and the slurry outlet of the slurry storage tank. The following description is based on the slurry flow control assembly being located at the slurry inlet of the slurry storage tank. The other two methods can refer to the implementation method of the slurry flow control assembly being located at the slurry inlet of the slurry storage tank.

[0038] When the above-mentioned slurry flow control component is located at the slurry inlet of the slurry storage tank, the controller can respectively obtain the flow detection information of the slurry flow detector included in the slurry flow control component and the additive flow detector included in the additive flow control component, and analyze the multiple flow detection information to determine that the mass of the slurry in the slurry storage tank is in a constant range, and when the additive flow is determined to be in the additive flow range corresponding to the slurry mass, the controller continuously receives the flow detection information of the slurry flow detector and the additive flow detector. When the controller determines that the flow of the slurry does not meet the requirements according to the flow detection information sent by the slurry flow detector and the additive flow detector, the controller can control the additive flow control valve to adjust the flow of the additive according to the additive flow detection information sent by the additive flow detector, so that the flow of the additive meets the requirements of the corresponding slurry. The flow of the slurry can also be adjusted by controlling the slurry control valve so that the flow of the slurry meets the requirements.

[0039] As a possible implementation, Figure 1 As shown, the additive dosing system 100 further includes an industrial control card 160, which is respectively connected to the controller 130 and the additive flow control component 122 included in each group of additive control pipelines 120. By setting the industrial control card 160, the communication between the additive flow control component 122 included in each group of additive control pipelines 120 and the controller 130 can be achieved.

[0040] In actual applications, the above-mentioned industrial control card is used to receive the additive flow detection information sent by the additive flow detector included in the additive flow control component included in each group of additive control pipelines, and convert the flow detection information and transmit it to the controller. When the controller needs to control the additive flow control valve, the controller sends the control signal to the industrial control card, and the industrial control card converts the converted control signal and sends it to the additive flow control valve, thereby realizing the flow control of the additive.

[0041] As a possible implementation, Figure 1 As shown, the additive dosing system 100 further includes a signal generator 170, which is respectively connected to the controller 130 and the industrial control card 160. The signal generator 170 can realize the communication between the industrial control card 160 and the controller 130.

[0042] As a possible implementation, Figure 1As shown, the additive dosing system 100 further includes at least one additive level detection device (not shown in the figure), each of which is disposed in a corresponding additive storage tank 110, and each of which is in communication with the controller 130. By providing the additive level detection device, the liquid level of the additive in the additive storage tank 110 can be controlled in real time to prevent the additive in the additive storage tank 110 from being insufficient.

[0043] As a possible implementation, Figure 1 As shown, the above-mentioned additive level detection device (not shown in the figure) may include an image collector, which is in communication connection with the controller 130. It should be understood that the image collector here may be a camera disposed in the additive storage tank 110.

[0044] When the above-mentioned liquid level detection device is a camera arranged in the additive storage tank, the camera can be used to capture the liquid level image in the additive storage tank, and the liquid level image can be sent to the controller, which analyzes the image to determine whether the liquid level of the additive in the additive storage tank is in a low liquid level state, and promptly alerts the staff to replenish the additive in the additive storage tank.

[0045] As a possible implementation, Figure 1 As shown, the additive level detection device (not shown) may include a level sensor, which is in communication with the controller 130. It should be understood that the level sensor may be a photoelectric level sensor, an ultrasonic level sensor, or a pipeline level sensor, etc., but is not limited thereto.

[0046] When the above-mentioned liquid level detection device is a liquid level detector such as a photoelectric liquid level sensor arranged in the additive storage tank, for example, the liquid level detection device is a photoelectric liquid level sensor arranged in the additive storage tank, and the photoelectric liquid level sensor can be installed on the inner wall of the additive storage tank. A beam of infrared rays is emitted at the transmitting end of the sensor, which is reflected by the surface of the additive level in the additive storage tank and then received by the receiving end of the sensor and converted into a liquid level signal and sent to the controller. The controller determines whether the liquid level of the additive in the additive storage tank is in a low liquid level state according to the liquid level signal, and promptly alerts the staff to replenish the additive in the additive storage tank.

[0047] As a possible implementation, the additive dosing system further includes at least one slurry level detection device, each slurry level detection device corresponds to a slurry storage tank, and each slurry level detection device is connected to the controller for communication. By setting a slurry level detection device in the slurry storage tank, the liquid level of the slurry in the slurry storage tank can be determined in real time, so that the quality of the slurry in the slurry storage tank can be determined to be in a constant state through the slurry level, thereby ensuring that the flow control of the additive is more accurate. It should be understood that the slurry level detection device here can refer to the relevant description of the additive level detection device in the previous text, and will not be repeated here.

[0048] As a possible implementation, Figure 1 As shown, the additive dosing system 100 further includes at least one stirring device (not shown in the figure), each stirring device is respectively arranged in the corresponding additive storage tank 110, and each stirring device is in communication connection with the controller 130. By providing the stirring device, the additive added to the slurry storage tank 140 can be ensured to be in a relatively uniform state to ensure the stability of the paper. At the same time, the stirring device can be controlled by the controller 130 to stir according to the preset stirring mode to achieve the effect of energy saving.

[0049] Exemplarily, each of the above-mentioned stirring devices may include a stirring motor and a stirring component connected to the stirring motor, wherein the stirring motor is connected to a controller for realizing opening and closing of the stirring device under the control of the controller. When the additive in the additive storage tank needs to be stirred, the stirring motor of the stirring device can be controlled by the controller to be in an on state, thereby controlling the rotation of the stirring component to realize stirring of the additive in the additive storage tank. It should be understood that the setting position of the stirring device here is mainly based on the solution that can be implemented in the present application, without too many restrictions. The stirring component may include a stirring shaft connected to the stirring motor and a rotating member connected to the stirring shaft, etc., but is not limited to this.

[0050] Taking into account the needs of energy saving and cost saving, the controller can be used to control the stirring motor to stir according to a preset stirring method. For example, stirring can be performed every 5 minutes, each time for 10 minutes, etc., but it is not limited to this.

[0051] As a possible implementation, Figure 1As shown, the additive dosing system 100 further includes an alarm component 180, which is connected to the controller 130 in communication, and includes at least one of a signal light, a voice prompter, and a prompt screen. The alarm component 180 is provided to alert the staff of abnormal conditions of the additive dosing system. It should be understood that the abnormal conditions here may include abnormal liquid level of the additive in the additive storage tank 110, abnormal liquid level of the slurry in the slurry storage tank 140, abnormal flow detection information sent by the additive flow detector 1221, and abnormal flow detection information sent by the slurry flow detector.

[0052] Exemplarily, the signal light may include three states of "red light", "green light" and "yellow light" or two states of "red light" and "green light" to alert the staff of abnormal conditions of the additive dosing system. For example, when the signal light 131 is "red light", it can be considered that the liquid level of the additive in the additive storage tank is in a low liquid level state, the liquid level of the slurry in the slurry storage tank is in a low liquid level state, the flow detection information sent by the additive flow detector is outside the flow range of the additive required in the slurry storage tank, or the flow detection information sent by the slurry flow detector is outside the normal flow range of the slurry in the slurry storage tank, etc. When the signal light 131 is "green light", it can be considered that the liquid level of the additive in the additive storage tank is in a normal state, the liquid level of the slurry in the slurry storage tank is in a normal state, the flow detection information sent by the additive flow detector is within the flow range of the additive required in the slurry storage tank, or the flow detection information sent by the slurry flow detector is within the normal flow range of the slurry in the slurry storage tank, etc.

[0053] Exemplarily, the voice prompter can be a voice speaker, which can play voice to remind the staff of abnormal conditions of the additive dosing system, so that the staff can make timely adjustments to ensure the normal operation of the additive dosing system. It should be understood that the voice speaker here is a commercially available product, and the specific model is not limited here, as long as it can meet the requirements of this disclosure.

[0054] For example, the above-mentioned prompt screen can be an LED screen, which can display words such as "normal", "XX abnormal", etc., so as to remind the staff to make timely adjustments to the abnormal situation of the additive dosing system. It should be understood that the LED screen here is a commercially available product, and the specific model is not limited here, as long as it can meet the requirements of this disclosure.

[0055] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0056] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
