Description

Technical Field

[0001] The invention relates to the technical field of raw material manufacturing, and in particular to a liquid material adding control device and system. Background Art

[0002] In the current raw material production, due to the wide variety of materials involved in the production process and the relatively small demand for each material, it is very difficult to accurately add materials. Traditional addition methods often rely on operators or simple automated equipment for delivery, but these methods are often difficult to achieve ideal precision control when processing small batches and multiple varieties of materials.

[0003] Even if the materials are accurately weighed before delivery to ensure that the amount of each material meets the formula requirements, there will still be significant errors in the actual delivery process. This error mainly comes from the transmission characteristics of the material in the pipeline. When the material flows through the pipeline, due to the friction between the material and the pipeline wall and the viscosity of the material itself, some of the material will adhere to the pipeline wall and cannot enter the production process smoothly. This phenomenon is particularly obvious when the amount of material is small, because although the amount of attached material is not large, it occupies a high proportion relative to the total amount, which is enough to have a significant impact on the material ratio.

[0004] In addition, due to the small amount of added materials, the part attached to the pipe wall is easily overlooked or underestimated. Under the existing monitoring methods, it is difficult to accurately measure and compensate for this part of the material, resulting in a deviation between the actual amount of material added and the expected amount. This deviation not only affects the ratio accuracy of the raw materials, and then affects the quality and performance of the final product, but may also cause waste of production costs and inefficient use of resources. Summary of the invention

[0005] The present invention aims to provide a liquid material addition control device and system to solve the problem in the prior art that it is difficult to achieve accurate addition amounts for a variety of added materials during the raw material production process, resulting in deviations between raw material production and expectations, affecting product quality.

[0006] To achieve the above purpose, the present invention adopts the following technical scheme, a liquid material addition control device and system, which analyzes the characteristics of various materials to be added and adopts different feeding methods to minimize the loss of materials during transportation, and is suitable for materials of various properties and viscosities. Only the metering tank and part of the feeding pipe are sprayed to ensure the accuracy of the material and reduce the generation of sewage. The liquid material adding control device comprises a production cylinder, and a powder material mechanism, an auxiliary agent mechanism, a liquid material mechanism and a water storage mechanism respectively connected to the feed port of the production cylinder; the production cylinder is a metering production cylinder; the powder material mechanism comprises a powder material tank, a powder material metering tank is provided at the outlet of the powder material tank, a powder material spiral path is provided at the outlet end of the powder material metering tank, and the powder is transported to the production cylinder in sections through the powder spiral path; the auxiliary agent mechanism comprises an auxiliary agent tank, an auxiliary agent metering tank is provided at the outlet of the auxiliary agent tank, an auxiliary agent pipeline is provided at the outlet end of the auxiliary agent metering tank, and the auxiliary agent flows into the production cylinder through the auxiliary agent pipeline by gravity; the liquid material mechanism comprises a liquid material tank, and the liquid material is transported into the production cylinder through a diaphragm pump delivery pipe; a spray mechanism is provided at the outlet of the water storage mechanism, and the spray mechanism is respectively connected to the production cylinder and the auxiliary agent mechanism.

[0007] At the same time, the present solution also provides a liquid material addition control system, which is applied to the above-mentioned liquid material addition control device, including a metering unit, a conveying control unit, a weighing unit, a spray control unit and a production control unit;

[0008] The metering unit is used to calculate the total amount of each material required for production according to the set single ton scale, and transmit the required total amount to the conveying control unit;

[0009] The conveying control unit is used to control the corresponding material tanks respectively, and deliver the materials into the corresponding metering tanks according to the total amount of each material;

[0010] The weighing unit is used to weigh the materials in each metering tank according to the set metering accuracy so that each material reaches the required total material dosage;

[0011] The conveying control unit is also used to deliver the material in the metering tank into the production cylinder according to the set feeding method after the weighing unit reaches the required total dosage; and control the water storage mechanism to deliver water to the spray mechanism and the production cylinder respectively according to the dosage;

[0012] The spray control unit is used to control the spray mechanism to spray and clean the production cylinder and the auxiliary agent mechanism;

[0013] The production control unit is used to control the production cylinder to start after the material is fed into the production cylinder, and to stop when the production cylinder is completed.

[0014] The principles and advantages of this solution are:

[0015] In the production process of raw materials, due to the wide variety of materials involved and the relatively small demand for each material, it is often difficult to achieve the ideal state in terms of addition accuracy. Even if the various materials are accurately weighed before the materials are added, they are often affected by equipment, conveying pipelines, etc., causing some materials to stick to the pipe wall during actual delivery and unable to enter the production process smoothly. This situation is especially obvious when the amount of material is small, because although the amount of attached materials is not large, it occupies a high proportion relative to the total amount, which affects the final quality of the product.

[0016] Generally, the amount of attached materials is often ignored or underestimated due to its small amount, and it is difficult to accurately measure and compensate for it under the existing monitoring methods, resulting in this part of the error being difficult to effectively compensate for. Even if the pipe wall can be cleaned by cleaning, a large amount of water is required for each of the various material conveying systems, and due to the limitations of the equipment structure, the amount of water used is not easy to control, which easily generates a large amount of wastewater.

[0017] Therefore, in this context, this scheme classifies the materials required for input according to their characteristics, and designs different metering accuracy and feeding methods according to the viscosity of each material characteristic, so as to minimize the loss of materials during transportation. Secondly, this scheme sets the metering tank at the conveying end of each material, and uses the weight-increasing method to perform cumulative weighing through the production cylinder, so that even if the material is attached during transportation, it will not affect the total amount of materials entering the production process, and the weighing accuracy can be guaranteed. In addition, after unloading, according to the characteristics of the auxiliary agent, in order to avoid the risk of pipeline crusting, the auxiliary agent metering tank, the production cylinder, and the auxiliary agent pipeline between the auxiliary agent metering tank and the production cylinder are sprayed and cleaned to ensure that the materials in this section can completely enter the production cylinder, and effectively reduce material loss and cleaning water. Because only this section is sprayed, the water used for production can be used in this scheme to ensure the accuracy of water use and fully meet the spraying requirements, and no excess wastewater will be generated, but it will be sent to the production cylinder together with the materials for production as materials.

[0018] Furthermore, the spray mechanism includes a high-pressure spray assembly and an external spray assembly; the high-pressure spray assembly is connected to the additive metering tank and the production cylinder respectively through a high-pressure spray pipe, and the external spray assembly is connected to the additive pipeline. The combination of the high-pressure spray assembly and the external spray assembly can reduce the intermediate filling preparation time of the high-pressure spray assembly and improve the conveying efficiency.

[0019] Furthermore, the metering accuracy of the production cylinder is 0.1kg, the metering accuracy of the powder metering tank is 1kg, and the metering accuracy of the additive metering tank is 0.1g; a manual ball valve is provided at the feed port of each metering tank. Different metering accuracies are used to ensure the accuracy of weighing each material and improve the accuracy of material control; the manual ball valve can avoid splashing of raw materials and further ensure the accuracy requirements of raw materials with different viscosities.

[0020] Furthermore, an auxiliary agent pneumatic valve is provided at the discharge port of the auxiliary agent tank, and the auxiliary agent pipeline is connected to the auxiliary agent pneumatic valve; the diaphragm pump delivery pipe includes a liquid material pneumatic valve provided at the discharge port of the liquid material tank, and a diaphragm pump is provided below the liquid material pneumatic valve.

[0021] Furthermore, a first spray head is provided inside the production cylinder, and a second spray head is provided inside the additive metering tank; the high-pressure spray assembly is connected to the first spray head and the second spray head respectively. Spray heads are provided in the production cylinder and the additive metering tank respectively, so that the inner wall can be cleaned to reduce material loss.

[0022] Furthermore, the single-ton standard is the standard dosage of each material required for one ton of product; each material includes a variety of additives, a variety of liquid materials, a variety of powder materials and water; the metering unit calculates the total dosage of each material according to the total amount of products that need to be produced.

[0023] Furthermore, the feeding method is to feed the additive into the production cylinder by gravity feeding; the liquid material is fed into the production cylinder by a diaphragm pump; the powder is fed into the production cylinder in sections by a spiral feeding method; and the water is fed into the production cylinder and the spraying mechanism by a screw pump.

[0024] Furthermore, the amount of water used by the spray control unit is part or all of the total amount of water weighed in the weighing unit.

[0025] Furthermore, the spray control unit is used to control the high-pressure spray component to spray and clean the inner walls of the additive metering tank and the production cylinder after the unloading is completed, and control the external spray component to spray and clean the additive pipeline.

[0034] Embodiment 1

[0035] This embodiment is basically as shown in the attached Figure 1 As shown, a liquid material addition control device can be applied to the transportation of materials of various properties and viscosities, and reduces the waste of production time and wastewater generated after switching between different feeding equipment. It can realize the flexible switching production of various product formulas, improve the accuracy of materials, and ensure product quality.

[0036] The liquid material adding control device is as shown in the attached Figure 1 As shown, it includes a production cylinder 1, and a powder mechanism 2, an auxiliary agent mechanism 3, a liquid mechanism 5 and a water storage mechanism 4 respectively connected to the feed port of the production cylinder 1. In this embodiment, the production cylinder 1 is a metering production cylinder, which is used for material mixing. During the production and mixing process, the material is weighed by the weight gain method to ensure that the total amount of the product meets the requirements and improve the weighing accuracy.

[0037] As attached Figure 2As shown, the powder mechanism 2 includes a plurality of powder tanks 8 for containing a variety of powder raw materials. A manual butterfly valve is also installed at the bottom of each powder tank 8 to control the powder conveying state and metering. A powder metering tank 15 is installed at the outlet of each powder tank 8, and a manual ball valve is also installed at the feed port of the powder metering tank 15. The manual ball valve can avoid the splashing of materials, and the accuracy requirements for materials with different viscosities can be further guaranteed. The required powders are fed into the powder metering tank 15 in sequence, and the powder metering tank 15 uses the weight gain method to weigh and measure each fed powder. In this embodiment, according to the characteristics of the powder and the required amount, the metering accuracy of the component metering tank 15 is set to 1kg to ensure the accuracy of the powder weighing.

[0038] A powder spiral 11 is installed at the outlet of the powder metering tank 15. When the total weight of the powder reaches the production amount, the powder is transported to the production cylinder 1 in sections through the powder spiral 11. In this embodiment, the powder spiral 11 is a spiral feeding channel. The powder is fed into the production cylinder 1 in sections by controlling the powder spiral 11 to start, and the spiral is closed after the weight is reached. This ensures the effectiveness of powder addition in production and avoids sticking, while ensuring accurate feeding of the powder.

[0039] As attached Figure 3 As shown, the additive mechanism 3 includes an additive tank 6, wherein the additive tank 6 includes a plurality of additive tanks, each of which is used to store a variety of different additive materials, such as a variety of bactericides, a variety of pH regulators, etc. In this embodiment, the additive tank 6 is mainly made of 316 stainless steel, and can be weighed and displayed by an electronic scale or a weighing instrument to display the total weight of the installed additives in real time.

[0040] An additive metering tank 14 is installed at the lower outlet of the additive tank 6. The additive tank 6 is installed above the additive metering tank 14. Various required additives flow into the additive metering tank 14 by gravity. In this embodiment, a manual ball valve is also installed at the feed port of the additive metering tank 14. The manual ball valve can avoid the splashing of materials and further ensure the accuracy requirements for materials with different viscosities. An additive pipeline 9 is installed at the outlet end of the additive metering tank 14. The additives flow into the production cylinder 1 through the additive pipeline 9 by gravity.

[0041] In this embodiment, an auxiliary agent pneumatic valve is installed at the discharge port of each auxiliary agent tank 6, and the auxiliary agent pneumatic valve 17 is connected to the auxiliary agent metering tank 14. When the corresponding auxiliary agent needs to be delivered, the pneumatic valve is opened to allow the auxiliary agent to enter the auxiliary agent metering tank 14 through the feed port by gravity feeding. The auxiliary agent metering tank 14 controls the amount of the auxiliary agent fed in by weight, and closes the corresponding auxiliary agent pneumatic valve when the weight reaches. In this embodiment, according to the characteristics of the auxiliary agent and the production dosage, the metering accuracy of the auxiliary agent metering tank 14 is set to 0.1g to ensure the accuracy and accurate control of the weighing of each auxiliary agent.

[0042] As attached Figure 4 As shown, the liquid material mechanism 5 includes a liquid material tank 7. In this embodiment, the liquid material tank 7 includes multiple liquid material tanks 7, each storing multiple liquid materials, including but not limited to various types of emulsions. The lower end of each liquid material tank 7 is connected to the production cylinder 1 through a diaphragm pump delivery pipe 10. The liquid material is delivered to the production cylinder 1 through the diaphragm pump delivery pipe 10. The delivered liquid material is weighed and calculated by the production cylinder 1. In this embodiment, the metering accuracy of the production cylinder 1 is 0.1kg. Since there are more materials in the production cylinder 1 and the production amount is large, the accuracy only needs to be 0.1kg, but the accuracy cannot be achieved for additives with smaller amounts. Therefore, this solution sets separate metering tanks for additives and powders to ensure accurate control of the amount of each material.

[0043] In this embodiment, the diaphragm pump delivery pipe 10 includes a liquid material pneumatic valve 18 installed at the outlet of each liquid material tank 7, and a diaphragm pump 19 is installed below the liquid material pneumatic valve. In this embodiment, the diaphragm pump is controlled to work by the weight of the mixing cylinder, so that the liquid material is sent into the production cylinder 1 under the action of the diaphragm pump. When the weight is reached, the corresponding liquid material pneumatic valve 18 and diaphragm pump 19 are controlled to be closed to ensure the accuracy of material addition.

[0044] As attached Figure 5 As shown, the water storage mechanism 4 includes a water storage tank 12, and a spray mechanism 16 is installed at the outlet of the water storage tank 12. The spray mechanism 16 is connected to the production cylinder 1 and the auxiliary agent mechanism 3 respectively.

[0045] In this embodiment, the water storage tank 12 is connected to the production cylinder 1 and the spray mechanism 16 through the screw pump pipe 13. A valve is installed at the water outlet of the water storage tank 12, and a screw pump is installed at the lower end of the valve. Water is sent into the production cylinder 1 through the screw pump, and part of the production water is sent into the spray mechanism 16 at the same time.

[0046] In this embodiment, the spray mechanism 16 includes a high-pressure spray component and an external spray component, wherein the high-pressure spray component is connected to the auxiliary agent metering tank 14 and the production cylinder 1 respectively through a high-pressure spray pipe, so as to facilitate spray cleaning of the inner walls of the production cylinder 1 and the auxiliary agent metering tank 14. The external spray component is installed on the auxiliary agent pipeline 9, so as to facilitate spray cleaning of the inside of the auxiliary agent pipeline 9.

[0047] Meanwhile, in this embodiment, a first spray head 20 is installed above the inside of the production cylinder 1, and a second spray head 21 is installed above the inside of the additive metering tank 14. The high-pressure spray assembly is connected to the first spray head 20 and the second spray head respectively, and the inner wall is cleaned by the first spray head 20 and the second spray head to reduce the loss of materials without causing excess cleaning wastewater, thereby ensuring the accuracy of production water.

[0048] In this embodiment, when the weight of the production water is reached, the valve and the screw pump are closed, and the auxiliary agent metering tank 14 and the auxiliary agent pipeline 9 are sprayed through the spraying mechanism 16. The water after spraying is sent to the production cylinder 1 to ensure that the materials are rinsed clean and all sent to the production cylinder 1, thereby ensuring the accuracy of material delivery and reducing the generation of wastewater.

[0049] In the production process of existing raw materials, due to the large number of raw materials required, there are more corresponding storage tanks. For different products, the types of raw materials required and the corresponding proportions will also be different. In addition, the characteristics of various raw materials are different. Therefore, the existing metering method generally adopts the method of weighing first and then putting in. However, for a wide variety of raw materials, it is difficult to accurately measure each type, and it is time-consuming and labor-intensive, which makes it difficult to fully meet the accuracy requirements in the proportioning and metering of raw materials. At the same time, this scheme finds that for raw materials with less required metering, even if the proportioning requirements are met during the initial weighing, they will more or less adhere to the conveying pipeline when they are put in. For raw materials with a small proportion, the adhered part will greatly affect the quality of the overall product, and this part is difficult to measure and make up for for the entire product production, thereby affecting the quality of the product and making it difficult to improve the product quality. If all metering equipment are to be integrated, the large number of them, the large space occupied, and the different metering standards of each metering equipment increase the difficulty of integration, making it difficult to achieve a balance between improving efficiency and ensuring accuracy.

[0050] In this embodiment, the raw materials are first classified according to their characteristics and divided into additives, liquid materials, powders and water to reduce the types of materials as much as possible. Different weighing and feeding modes are used for different materials such as additives, liquid materials, powders and water, and the material residues in the same pipeline can be washed with water through formula design to avoid the risk of pipeline crusting. At the same time, different feeding methods are adopted to effectively reduce the steps of material transportation, realize flexible switching of various product formulas, reduce the switching time of intermediate equipment, and improve production efficiency. At the same time, this scheme can be applied to the transportation of materials of various different properties and viscosities, and spraying is only performed at the additive metering tank and the additive pipeline 9. While ensuring the accuracy of the material, the use of spray water is reduced, and the generation of wastewater is reduced. Moreover, since it is only used at the feeding structure, production water can be directly used to meet the spraying requirements while comprehensively utilizing water, improving the utilization rate and ensuring the accuracy of the dosage.

[0051] Embodiment 2

[0052] This embodiment provides a liquid material addition control system, which is applied to the above-mentioned liquid material addition control device, such as the attached Figure 6 As shown, it includes a metering unit, a conveying control unit, a weighing unit, a spray control unit and a production control unit.

[0053] The metering unit is used to calculate the total amount of each material required for production according to the set single ton standard, and transmit the required total amount to the conveying control unit.

[0054] In this embodiment, the single ton standard quantity is the standard dosage of each material required for one ton of product, wherein each material includes multiple additives, multiple liquid materials, multiple powder materials and water. For example, one ton of type A product requires 6 additives, 5 liquid materials, 4 powder materials and 1 tap water. Then, according to the ratio of various materials, the corresponding material dosage is entered to form the standard dosage of a single product for the next ton. When it is necessary to produce type A products, the corresponding total production volume is input, and the metering unit calculates the total dosage of each corresponding material according to the total amount of products to be produced.

[0055] After receiving the calculated total dosage, the conveying control unit controls the corresponding material tanks according to the total dosage, and feeds the materials into the corresponding metering tanks in different feeding methods according to the total dosage of each material.

[0056] The weighing unit is used to weigh and calculate the materials in each metering tank according to the set metering accuracy by using the weight gain method to achieve the required total material dosage.

[0057] The conveying control unit is also used to deliver the materials in each metering tank into the production cylinder 1 according to the set feeding method after the weighing unit reaches the required total dosage; and control the water storage mechanism to deliver water to the spray mechanism 16 and the production cylinder 1 according to the dosage, and automatically stir.

[0058] In this embodiment, the feeding method is to feed the auxiliary agent into the production cylinder 1 by gravity feeding. When the weight is reached, the pneumatic valve is closed accordingly. After the weight is reached, the system controls to automatically feed it into the production cylinder 1 for stirring. The liquid material is fed into the production cylinder 1 by a diaphragm pump, and the diaphragm pump is controlled by the weight of the stirring cylinder. After the weight is reached, the pneumatic valve and the diaphragm pump are closed accordingly. The powder material is fed into the production cylinder 1 in sections by a spiral feeding method, and the corresponding spiral is closed after the cumulative weight is reached. Water is fed into the production cylinder 1 and the spray mechanism 16 by a screw pump.

[0059] The spray control unit is used to control the spray mechanism 16 to spray and clean the production cylinder 1 and the auxiliary agent mechanism. In this embodiment, the amount of water used by the spray control unit is part or all of the total amount of water weighed in the weighing unit. Among them, the spray control unit is mainly used to control the high-pressure spray component to spray and clean the inner wall of the auxiliary agent metering tank 14 and the production cylinder 1 after the material is unloaded, and control the external spray component to spray and clean the auxiliary agent pipeline 9.

[0060] The production control unit is used to control the production cylinder 1 to start after the material is fed into the production cylinder 1, and stop when it is completed. At the same time, in this embodiment, after the stirring reaches the stirring time, the inner wall of the production cylinder 1 can also be cleaned by operating the external spray component to further ensure the cleanliness of the equipment and avoid the generation of sewage during subsequent cleaning. After passing the test, the equipment is controlled to stop automatically. At the same time, in the product packaging process, in order to prevent precipitation, the system controls stirring for 2 minutes every 40 minutes to further ensure the uniformity of the raw materials.

[0061] In this embodiment, the single-ton scalar method is adopted, and the required material dosage can be flexibly set according to the products to be produced, and the total dosage of the required materials can be quickly obtained according to the input production volume, thereby improving the proportioning efficiency, ensuring the standardization and accuracy of the dosage, and reducing waste and proportioning time. At the same time, in the prior art, due to the different material properties, different weighing methods are used, resulting in a complicated and difficult to calculate metering process, and the accuracy of the material cannot be ensured. However, this scheme adopts the incremental method, and adopts different weighing and feeding methods according to the different material properties. After targeted and separate metering, the weight is calculated after being sent to the production cylinder 1, thereby improving the accuracy of the weighing, and a 40-step operation can be achieved. A manual ball valve is added at the tail end of the feeding structure to control the feed weight, so as to control the feeding accuracy under different viscosities and improve accuracy.

[0062] After unloading, different materials are rinsed to reduce material adhesion, reduce material loss, reduce weight error, and avoid the risk of pipe crusting. At the same time, the cleaning water adopts two methods: high-pressure spraying of the same pipeline pressure-stabilizing pump and manual spraying, which is convenient to reduce the waste of high-pressure water gun preparation time when switching product production and improve overall production efficiency.

[0063] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
