DETAILED DESCRIPTION

[0021] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0022] It should be noted that all technical and scientific terms used in the present application have the same meaning as that generally understood by ordinary skilled persons in the technical field to which the present application belongs, unless otherwise specified.

[0023] In the present application, unless otherwise stated, the orientation words such as "upper, lower, top, bottom" used are generally directed to the directions shown in the drawings, or are directed to the vertical, perpendicular or gravity directions of the components themselves. Similarly, for the convenience of understanding and description, "inner, outer" refers to the inner and outer relative to the contour of each component itself, but the above orientation words are not used to limit the present application.

[0024] In order to solve the problem of long mixing time of auxiliary materials in the single cone device in the prior art, the present application provides a spraying and feeding device.

[0025] As shown in Figure 1 The spraying and feeding device is used for spraying solution into the single cone device 50, and the spraying and feeding device comprises a stirring mechanism 10, a storage mechanism 20 and a spraying mechanism 30 which are sequentially communicated. The stirring mechanism 10 is used for stirring the solution and delivering the solution into the storage mechanism 20. The storage mechanism 20 is used for storing the solution and delivering the solution into the spraying mechanism 30. The spraying mechanism 30 is used for spraying the solution into the single cone device 50.

[0026] By arranging the stirring mechanism 10, the solution is stirred uniformly in the stirring mechanism 10, and the uniformly mixed solution is stored in the storage cavity 21. When the single cone device 50 needs to add auxiliary materials, the spraying mechanism 30 sprays the auxiliary material solution into the single cone device. Since the auxiliary materials are mixed with water to form a solution in the stirring cavity 11 and are uniformly mixed with water under the stirring action of the stirring mechanism 10, the spraying mechanism 30 sprays the auxiliary material solution into the single cone device 50. Since the auxiliary materials are sprayed into the single cone device 50 in the form of solution and mixed with the materials, the caking of the auxiliary materials is effectively avoided. In addition, the auxiliary materials are added in the form of spraying during the stirring of the materials, which is conducive to the uniform mixing of the auxiliary materials and the materials, and shortens the mixing time of the materials and the auxiliary materials in the single cone device 50. Since the single cone device 50 has a high temperature, the auxiliary materials are added in the form of solution spraying during the stirring of the materials, which does not affect the drying of the materials by the single cone device 50.

[0027] It should be noted that the above-mentioned solution is a solution of auxiliary materials and water or a solution of medicine and water, which can be designed according to the use requirements.

[0028] As shown in Figure 1As shown, the spray feeding device also includes a temperature control mechanism 40, which is connected to both the stirring mechanism 10 and the storage mechanism 20. The temperature control mechanism 40 is used to control the temperature of the environment in which the auxiliary materials are placed in the stirring mechanism 10 and the storage mechanism 20. Temperature is a key factor that affects the dissolution and mixing rate of auxiliary materials. Through the temperature control mechanism 40, the temperature in the stirring mechanism 10 can be adjusted to the optimal dissolution and mixing temperature, thereby accelerating the dissolution of auxiliary materials in water and improving the uniformity and efficiency of auxiliary material mixing. This is especially important for auxiliary materials that are easily soluble in water, ensuring that the auxiliary materials can be quickly and fully dissolved, avoiding the presence of undissolved particles in subsequent processes, which can affect material performance. In the storage mechanism 20, the temperature control mechanism 40 can maintain the optimal temperature of the auxiliary materials during storage, preventing changes in the physical or chemical properties of the auxiliary materials due to temperature changes, such as crystallization, polymerization, etc. This not only ensures the quality of the auxiliary materials, but also reduces production failures caused by changes in the properties of the auxiliary materials, enhancing the reliability of the entire production process. By precisely controlling the temperature, it can ensure that the auxiliary materials are mixed and stored under optimal reaction conditions, avoiding deterioration or incomplete reaction of the auxiliary materials due to temperature fluctuations, especially suitable for temperature-sensitive chemical reactions and biopharmaceutical processes. The addition of the temperature control mechanism 40 makes the device adaptable to different reaction conditions of auxiliary materials, improving the versatility and stability of the device.

[0029] Optionally, the temperature control mechanism 40 is connected to the stirring mechanism 10 and the storage mechanism 20 through a hose to reduce the impact of vibration on the weighing.

[0030] The pipes in the temperature control mechanism 40 can be made of stainless steel, carbon steel, PP, or other materials. The valve control in the temperature control mechanism 40 can be selected from pneumatic valves, solenoid valves, etc. The temperature feedback can be selected from thermocouples, thermal resistors, etc. The heating method can be selected from electric heating, gas heating, etc. The cooling method can be selected from air cooling, water cooling, etc., which is beneficial for selection and cost control according to different working conditions.

[0031] As shown in Figure 1 The stirring mechanism 10 includes a stirring chamber 11, a first feeding port, and a water inlet port that communicate with the stirring chamber 11. The storage mechanism 20 is connected to the stirring mechanism 10 and includes a storage chamber 21 for storing the stirred solution. The spraying mechanism 30 communicates with the storage mechanism 20, and a portion of the spraying mechanism 30 is located in the single-cone device 50 and is signal-connected to the single-cone device 50. The spraying mechanism 30 is used to spray the solution into the single-cone device 50.

[0032] By setting the stirring mechanism 10, and by adding the auxiliary materials into the stirring cavity 11 through the first feeding port, and by adding water through the water inlet, the auxiliary materials and water are uniformly mixed into a solution in the stirring cavity 11, and the uniformly mixed solution is stored in the storage cavity 21, the spraying mechanism 30 is signal connected with the single-cone device 50, and when the single-cone device 50 needs to add auxiliary materials, the spraying mechanism 30 sprays the solution to the single-cone device, since the auxiliary materials are mixed with water to form a solution in the stirring cavity 11, and the auxiliary materials and water are uniformly mixed under the action of the stirring piece 14. Part of the spraying mechanism 30 is located inside the single-cone device 50, and the solution is sprayed into the single-cone device 50, since the auxiliary materials are sprayed into the single-cone device 50 in the form of a solution and mixed with the materials, the situation of auxiliary material caking is effectively avoided, and at the same time, the auxiliary materials are added in the form of spraying during the stirring of the materials, which is beneficial to the uniform mixing of the auxiliary materials and the materials, and shortens the mixing time of the materials and the auxiliary materials in the single-cone device 50. At the same time, the single-cone device 50 includes a relatively high temperature, and the solution is added in the form of spraying during the stirring of the materials, which also does not affect the drying of the materials by the single-cone device 50.

[0033] The spraying dosing device realizes the automation of the auxiliary material adding process through the integrated stirring mechanism 10, storage mechanism 20 and spraying mechanism 30. Compared with the traditional manual addition of auxiliary materials, the automatic feeding reduces the dependence on manpower, reduces labor costs, and also avoids the inaccuracy that may be caused by human operation, thereby improving the accuracy and consistency of the feeding process.

[0034] In some optional embodiments, the stirring mechanism 10 further includes a quantitative control assembly, which is arranged at the first feeding port and the water inlet to accurately control the amount of auxiliary materials and water entering the stirring cavity 11.

[0035] As shown in Figure 1 The stirring mechanism 10 includes a stirring assembly 12 and a transfer assembly 13, the stirring assembly 12 includes a stirring cavity 11 and a stirring piece 14, the stirring piece 14 is at least partially located in the stirring cavity, the stirring cavity 11 is provided with a first feeding port, a water inlet and a discharge port 121, the stirring assembly 12 is connected with the storage mechanism 20 through the transfer assembly 13, the transfer assembly 13 is connected with the discharge port 121, and the transfer assembly 13 is used to transfer the solution in the stirring cavity 11 to the storage mechanism 20.

[0036] The arrangement of the stirring assembly 12 ensures effective mixing of the auxiliary materials and pure water in the stirring cavity 11. The design of the stirring member 14 can accelerate the mixing speed of the auxiliary materials and pure water, and greatly improve the uniformity of the mixing of the auxiliary materials, thereby solving the problem of uneven mixing of auxiliary materials existing in the traditional manual addition and premixing equipment. The discharge port 121 in the stirring assembly 12 is connected with the transfer assembly 13, realizing automatic and quantitative transfer of the auxiliary materials from the stirring completion to the storage mechanism 20. This process avoids the inaccuracy and inefficiency of manual operation, improves the automation degree of the whole system operation, reduces the manual intervention, and reduces the possibility of operation errors. Through the effective connection of the transfer assembly 13 and the storage mechanism 20, the rapid and stable transfer of the auxiliary materials is realized, avoiding the secondary pollution and loss of the auxiliary materials in the transfer process, and ensuring the continuity and high efficiency of the auxiliary materials from stirring to storage. This not only speeds up the production rhythm, but also provides necessary technical support for continuous production, which helps to release the production capacity.

[0037] In some optional embodiments, the stirring member 14 can further include a stirring paddle and a stirring drive machine, the stirring drive machine drives the stirring paddle to rotate, thereby uniformly mixing the auxiliary materials and water in the stirring cavity 11.

[0038] It should be noted that the stirring assembly 12 can also include an overflow port, a first weighing module, etc., which can be designed according to actual needs, and is not limited here. For example, the first weighing module is arranged at the bottom of the stirring cavity 11.

[0039] In some optional embodiments, referring to Figure 1 , the transfer assembly 13 includes a transfer pipeline 131 and a transfer pump 132, one end of the transfer pipeline 131 is connected with the discharge port 121, the other end of the transfer pipeline 131 is connected with the storage mechanism 20; the transfer pump 132 is arranged on the transfer pipeline 131. By arranging the transfer pump 132 on the transfer pipeline 131, it can ensure that the stirred auxiliary materials can be smoothly and quickly transferred from the discharge port 121 of the stirring mechanism 10 to the storage mechanism 20, avoiding the problems of blockage or low transmission efficiency caused by poor flowability of the auxiliary materials or pipeline resistance. This guarantees the continuity of the feeding process, shortens the residence time of the auxiliary materials in the pipeline, thereby reducing the possible chemical reaction or physical property change of the auxiliary materials in the transmission process. The automatic design of the transfer assembly 13, i.e. the use of the transfer pump 132, reduces the dependence on manual operation, and the transfer process of the auxiliary materials can be automatically performed without manual intervention. This not only saves human resources, but also improves the accuracy and safety of the operation, and reduces the errors and risks caused by human operation.

[0040] Optionally, the connection mode of the transfer pipeline 131 and the discharge port 121 is soft connection, so as to reduce the influence on the stirring assembly 12, especially the influence of the transfer pump 132 on the first weighing module.

[0041] Optionally, the transfer pump 132 can be a pneumatic diaphragm pump, a centrifugal pump, a vane pump, etc. to facilitate the use in different working conditions and solutions.

[0042] In some optional embodiments, referring to Figure 1 , the stirring assembly 12 comprises a second feeding port 122, which is arranged on the stirring cavity 11. The transfer assembly 13 further comprises an auxiliary pipeline 133, a first control valve 134 and a second control valve 135. One end of the auxiliary pipeline 133 is connected with the second feeding port 122, and the other end of the auxiliary pipeline 133 is connected with the transfer pipeline 131. The connection point of the auxiliary pipeline 133 and the transfer pipeline 131 is located downstream of the transfer pump 132. The first control valve 134 is arranged on the transfer pipeline 131, and the connection point of the auxiliary pipeline 133 and the transfer pipeline 131 is located upstream of the first control valve 134. The second control valve 135 is arranged on the auxiliary pipeline 133. The connection of the auxiliary pipeline 133 and the second feeding port 122, and the connection point of the auxiliary pipeline 133 and the transfer pipeline 131 located downstream of the transfer pump 132 form a circulating path of the auxiliary material. This makes the auxiliary material at the bottom of the stirring cavity 11 flow back to the top of the stirring cavity 11 through the transfer assembly 13 during the stirring process of the auxiliary material in the stirring cavity 11, so that the auxiliary material circulates in the stirring cavity 11, further improving the uniformity of the auxiliary material mixing. The arrangement of the first control valve 134 and the second control valve 135 can control whether the auxiliary material in the transfer pipeline 131 flows to the storage mechanism 20 or flows back to the stirring cavity 11, so that the circulation of the auxiliary material in the stirring cavity 11 and the transfer of the auxiliary material to the storage mechanism 20 share the same equipment, which is conducive to reducing the number of equipment and the space occupied by the spray feeding device.

[0043] It should be noted that the materials of the stirring assembly 12, the auxiliary pipeline 133 and the transfer pipeline 131 of the stirring mechanism 10 can be selected from stainless steel, carbon steel, PP and other materials. The temperature control can be in the form of a jacket or a coil. The stirring mechanism 10 can further comprise a liquid level control member, which can be selected from a mechanical floating ball, a liquid level flap valve and other structures. The stirring assembly 12 can be placed in a suspended or floor-standing manner. The auxiliary material can be added manually or automatically by full-automatic metering and automatic feeding. The stirring method can be manual stirring, mechanical stirring, magnetic stirring, ultrasonic stirring and gas stirring. The form of the stirring member 14 can be paddle type, turbine type, frame type, anchor type, propeller type, screw type, screw belt type and other forms. The first control valve 134 and the second control valve 135 can be selected from pneumatic valves, solenoid valves and other forms. The stirring assembly 12 can be provided with a heat preservation sleeve, and the material of the heat preservation sleeve can be selected from polystyrene foam board, rock wool board, glass wool board and other materials, which is conducive to selection and cost control according to different working conditions.

[0044] In some optional embodiments, referring to Figure 1The storage mechanism 20 includes a storage tank 22 and a circulating assembly 23. The storage tank 22 includes a storage cavity 21. The stirring mechanism 10 is connected to the storage tank 22 and communicates with the storage cavity 21. The circulating assembly 23 communicates with the top and bottom of the storage cavity 21 and is used to send the auxiliary materials at the bottom of the storage cavity 21 to the top of the storage cavity 21. The storage cavity 21 of the storage tank 22 provides a stable and safe storage space for the mixed auxiliary materials. Through reasonable design of the storage cavity 21, such as material, heat preservation method, and placement method, it can be ensured that the auxiliary materials will not be affected by the external environment (such as temperature change and dust pollution) during storage, and the stability of the auxiliary materials can be maintained. The introduction of the circulating assembly 23 solves the problem of auxiliary material precipitation caused by long-term standing. By sending the auxiliary materials at the bottom of the storage cavity 21 to the top, the internal circulation of the auxiliary materials is realized, the deposition of the auxiliary materials to the bottom under the action of gravity is effectively avoided, the uniformity of the auxiliary materials is ensured, and the uniformity of the feeding during the spraying process is ensured.

[0045] It should be noted that in the state of the storage cavity 21 in operation, the solution is prone to deposit at the bottom of the storage cavity 21 under the action of gravity. In this application, the storage cavity 21 is evenly divided into three regions along the direction of gravity, and each region occupies one third of the volume of the storage cavity 21. The bottom of the storage cavity 21 can be understood as the region near the bottom end of the storage cavity 21 in the direction of gravity, which occupies one third of the volume of the storage cavity 21. The top of the storage cavity 21 can be understood as the region near the top end of the storage cavity 21 in the direction of gravity, which occupies one third of the volume of the storage cavity 21. In some embodiments, the circulating assembly 23 is connected to the top and bottom of the storage cavity 21.

[0046] In some optional embodiments, the storage mechanism 20 further includes a second weighing module, which is arranged at the bottom of the storage cavity 21.

[0047] In some optional embodiments, please refer to Figure 1 The circulating assembly 23 includes a circulating pipeline 231 and a circulating pump 232. The two ends of the circulating pipeline 231 are connected to the storage tank 22. One end of the circulating pipeline 231 communicates with the top of the storage cavity 21, and the other end of the circulating pipeline communicates with the bottom of the storage cavity 21. In other embodiments, one end of the circulating pipeline 231 is connected to the bottom end of the storage tank 22, the other end of the circulating pipeline 231 is connected to the top end of the storage tank 22, and the two ends of the circulating pipeline 231 communicate with the storage cavity 21. The circulating pump 232 is arranged on the circulating pipeline 231. The use of the circulating pump 232 makes the circulation of the auxiliary materials in the storage cavity 21 more stable and efficient, which helps to maintain the uniformity of the auxiliary materials. The stable operation of the circulating pump 232 ensures that the auxiliary materials in the storage cavity 21 always maintain a good circulating state, avoids excessive concentration or dilution of the auxiliary materials in a local area, and improves the stability of the product quality.

[0048] The main body of the storage mechanism 20 and the pipeline can be made of stainless steel, carbon steel, PP or other materials, the temperature control can be in the form of a jacket, a coil, etc., the storage mechanism 20 can further include a liquid level control module, which can be made of a mechanical floating ball, a liquid level flap valve or other structures, the storage tank 22 can be placed in a suspended or floor-standing manner, the liquid flow mode can be selected from physical stirring, liquid circulation, etc., the circulating pump 232 can be selected from a pneumatic diaphragm pump, a centrifugal pump, a vane pump, etc., the valve control in the storage mechanism 20 can be selected from a pneumatic valve, an electromagnetic valve, etc., and the storage tank 22 can be provided with a heat preservation structure, which can be made of polystyrene foam board, rock wool board, glass wool board or other materials, which is beneficial to selection and cost control according to different working conditions.

[0049] In some optional embodiments, referring to Figure 1 , the spraying mechanism 30 includes a quantitative spraying assembly 31 and a backflow assembly 32, the quantitative spraying assembly 31 is in communication with the storage cavity 21 and the single-cone device 50, and the backflow assembly 32 is in communication with the quantitative spraying assembly 31 and the storage cavity 21. The backflow assembly 32 is mainly designed to remove air or auxiliary materials remaining after the last spraying in the quantitative spraying assembly 31 before spraying, so as to ensure the purity and uniformity of the sprayed auxiliary materials. The backflow assembly 32 returns the auxiliary materials not sprayed or containing air in the quantitative spraying assembly 31 to the storage cavity 21 for recycling, thereby avoiding the air or impurities from entering the single-cone device to affect the uniformity of the auxiliary material mixing and the process effect. This feature is of great significance to improve the reliability of the spraying process and the consistency of the auxiliary material processing.

[0050] Optionally, the circulating pipeline 231 and the quantitative spraying assembly 31 and the bottom of the storage cavity 21 are all soft connections, so as to reduce the influence of the power element on the storage cavity 21, especially the influence on the second weighing module in the storage cavity 21.

[0051] In some optional embodiments, referring to Figure 1, the quantitative spraying assembly 31 includes a delivery pipe 311, a metering pump 312, at least one spraying pipe 313, at least one flow meter 314, at least one spraying control valve 315, and at least one spraying head, the delivery pipe 311 is in communication with the bottom of the storage cavity 21; the metering pump 312 is arranged on the delivery pipe 311; the first end of the spraying pipe 313 is in communication with the delivery pipe 311, and the second end of the spraying pipe 313 is adapted to be in communication with the single-cone device 50; at least one flow meter 314 is arranged on each spraying pipe 313, the backflow assembly 32 is in communication with the plurality of spraying pipes 313, and the connection point of the backflow assembly 32 with the spraying pipe 313 is located downstream of the flow meter 314; at least one spraying control valve 315 is arranged on each spraying pipe 313, and the spraying control valve 315 is located downstream of the flow meter 314; and the second end of each spraying pipe 313 is provided with at least one spraying head. The arrangement of the metering pump 312 ensures that the delivery amount of the spraying auxiliary material reaches a high degree of accuracy. By adjusting the parameters of the metering pump 312, fine adjustment of the spraying amount can be realized, ensuring that the auxiliary material addition amount of each spraying meets the process requirements, which is crucial for high-precision lithium battery positive electrode material production. The design of the spraying pipe 313 and the spraying head enables the auxiliary material to be uniformly distributed inside the single-cone device 50, and the spraying pipe 313 and the spraying head can be multiple, which can avoid the over or under of some auxiliary materials due to uneven spraying, thereby affecting the performance of the final product. The position and design of the spraying head can be further optimized to adapt to different production stages and auxiliary material properties, improving the spraying uniformity. The flow meter 314 arranged on each spraying pipe 313 can monitor the flow in each spraying pipe 313 in real time, ensuring the continuity, stability, and uniformity of the spraying process. Monitoring of flow data provides real-time feedback for the spraying process, which helps to adjust the opening of the corresponding spraying control valve 315 in time to maintain a constant spraying rate, thereby improving the precision and efficiency of spraying. The introduction of the backflow assembly 32 solves the problem of clogging of the spraying pipe 313 in the non-spraying state. By setting the connection point of the spraying pipe 313 with the backflow assembly 32 downstream of the flow meter, it can be ensured that the liquid in the spraying pipe 313 can flow back to the storage cavity 21 when not spraying, avoiding the crystallization or solidification of the residual auxiliary material in the pipe, protecting the spraying head, and reducing maintenance costs.

[0052] In addition, the automatic control of the spray control valve 315, combined with the data of the flow meter, realizes the automation and intelligence of the spraying process. Through the pre-set spraying control strategy, such as flow threshold, spraying time, etc., the spraying process can be accurately controlled without manual intervention, improving the production efficiency and safety. The design of multiple spray pipes 313 and spray heads provides flexible production line adjustment capability. According to the production requirements and equipment status, some spray pipes can be selectively turned on or off, and the position and spraying angle of the spray head can be adjusted to adapt to different types of auxiliary material processing, improving the adaptability and flexibility of the production line.

[0053] Alternatively, since the end spray head is inserted into the interior of the single-cone device 50, considering that the single-cone device 50 is a vacuum-drying device, the spray pipe 313 inserted into the contact portion needs to be connected using a sleeve to ensure sealing and high-temperature resistance. The spray head type can be selected from water mist type, direct type, etc., the sealing method of the spray pipe 313 and the single-cone device 50 can be selected from corrugated pipe sealing, O-ring sealing, hydraulic sealing, etc., and the number of spray pipes 313 can be added according to actual equipment requirements, which is beneficial to selection and cost control according to different working conditions.

[0054] In some embodiments, in order to facilitate the staff to control the flow in the conveying pipe 311, the spray head is located in the single-cone device 50, and the metering pump 312, at least one flow meter 314 and one spray control valve 315 are located outside the single-cone device 50.

[0055] In some optional embodiments, referring to Figure 1 , the backflow assembly 32 includes a backflow main pipe 321, at least one backflow branch pipe 322 and at least one backflow control valve 323. One end of the backflow main pipe 321 is in communication with the storage cavity 21. One end of the backflow branch pipe 322 is connected with the backflow main pipe 321, the other end of the backflow branch pipe 322 is connected with the spray pipe 313, and the connection point of the backflow branch pipe 322 and the spray pipe 313 is located between the flow meter 314 and the spray control valve 315. At least one backflow control valve 323 is arranged on each backflow branch pipe 322. The design of the backflow assembly, especially the connection point of the backflow branch pipe 322 and the spray pipe 313 located between the flow meter 314 and the spray control valve 315, can effectively empty the air or uneven solution in the spray pipe 313, ensuring that the solution in the pipe is in a stable state before spraying, thereby improving the metering accuracy of the metering and spraying system. Before spraying starts, the backflow control valve 323 is opened, and the solution circulates between the backflow branch pipe 322 and the spray pipe 313 to discharge air, ensuring that the flow meter can accurately measure the amount of solution during spraying, avoiding metering errors caused by air or uneven solution in the pipe.

[0056] In addition, the pre-circulation function of the backflow assembly 32 can effectively reduce the risk of clogging the spray head. Before spraying, the impurities or incompletely dissolved solid particles in the pipeline are brought back to the storage chamber through backflow circulation, avoiding the clogging of the spray head by these impurities, ensuring the smoothness of the spraying process, and improving the spraying efficiency and uniform distribution of the auxiliary materials. The design of the backflow assembly 32 also helps to improve the utilization efficiency of auxiliary materials. After the spraying is completed, the residual solution in the pipeline can be returned to the storage chamber 21 through the backflow branch pipeline 322 and the backflow main pipeline 321, avoiding waste of auxiliary materials, which is particularly important for handling expensive or scarce auxiliary materials, helping to reduce production costs. The operation of the backflow assembly 32 can serve as a system self-cleaning method, and regular or on-demand use of backflow circulation can clean the spraying pipeline 313, prevent pipeline clogging or corrosion caused by residual auxiliary materials, prolong the service life of the equipment, and reduce maintenance work.

[0057] The pipeline in the spraying mechanism 30 can be made of stainless steel, carbon steel, PP, or other materials, and the metering pump 312 can be selected from a plunger metering pump, a diaphragm metering pump, etc.

[0058] In some optional embodiments, referring to Figure 1 A third control valve 317 can be provided on the conveying pipeline 311 to control the flow of materials in the storage chamber 21 into the conveying pipeline 311. A filter 318 is located downstream of the third control valve 317, one pressure control valve 319 is located downstream of the filter 318 and upstream of the metering pump 312, and the other pressure control valve 319 is located downstream of the metering pump 312. The pressure control valve 319 can be selected from a pressure relief valve, a pressure stabilizing valve, a safety valve, etc., and the filter can be selected from a Y-type filter, a safety filter, etc.

[0060] Step one: open the water inlet and close it when the water inflow reaches the set value;

[0061] Step two: open the first feeding port, add the pre-set weight of auxiliary materials from the first feeding port to the stirring chamber 11, close the first feeding port, and start the stirring assembly 12.

[0062] Step three: the stirring part 14 starts to work, and the transfer pump 132 of the transfer assembly 13 starts to work, the first control valve 134 is closed, the fourth control valve 136 is opened, the internal circulation of the stirring chamber 11 is started to ensure the uniformity of the solution in the stirring chamber 11, and the temperature control mechanism 40 is started to control the temperature in the stirring chamber 11.

[0063] Step four: when the stirring time reaches, the stirring part 14 stops working, the first control valve 134 opens, the second control valve 135 closes, and the solution starts to be transferred to the storage mechanism 20, and the temperature control mechanism 40 stops working.

[0064] Step five: when the actual weight displayed by the weighing module in the stirring cavity 11 is lower than the preset lower limit value, it indicates that the auxiliary material solution in the stirring cavity 11 has been completely transferred to the storage mechanism 20, the fourth control valve 136 closes, and the transfer pump 132 closes.

[0065] Step six: when the actual weight displayed by the weighing module in the storage tank 22 is higher than the set value, the circulating assembly 23 is started, the internal circulation of the storage mechanism 20 is opened, and the temperature control mechanism 40 is started to control the temperature in the storage cavity 21.

[0066] Step seven: when the single-cone device 50 sends a signal indicating that spraying can be performed, the third control valve 317 opens, the metering pump 312 starts to work, the spraying control valve 315 closes, and the backflow control valve 323 opens, and the solution starts to circulate to discharge the air in the pipeline of the quantitative spraying assembly 31 to the storage mechanism 20.

[0067] Step eight: when the backflow assembly 32 operates for a set time, the backflow control valve 323 closes, the spraying control valve 315 opens, and the flow meter 314 starts to work to record the flow of the corresponding spraying pipeline 313.

[0068] Step nine: the flow meter 314 is observed and adjusted, so that the real-time three flow meters 314 data remain consistent, when the cumulative flow of the multiple flow meters 314 reaches a set flow, the third control valve 317 closes, the metering pump 312 closes, the spraying control valve 315 closes, and the flow meter 314 flow is cleared for the next preparation.
