Description

Technical Field

[0001] This application relates to the technical field of accelerator production, and in particular to an automatic proportioning device for accelerator production. Background Technology

[0002] Accelerators are admixtures added to concrete to enable it to set and harden rapidly. Accelerators are composed of various raw materials mixed in specific proportions; therefore, precise proportioning of raw materials is a crucial step in ensuring product quality during the production process.

[0003] However, existing mixing devices struggle to achieve coordinated control of dynamic and accurate metering and stable delivery of raw materials. Specifically, traditional accelerator production requires mixing various powder raw materials in specific proportions. These raw materials often clump together due to their hygroscopic nature, leading to poor material flow, affecting delivery stability, and consequently causing mixing errors. Furthermore, existing devices require manual weighing of the raw materials needed for each batch, followed by manual or elevator transport to a raw material cylinder for temporary storage. During production, the materials are directly discharged from the cylinder. This transfer process reduces the metering accuracy of each batch, resulting in significant mixing errors. The need for manual weighing further reduces production efficiency. Utility Model Content

[0004] To address the issue of raw material agglomeration causing poor material flow, the current method involves manually weighing the raw materials required for each batch and then manually or via elevator transporting them to a raw material cylinder for temporary storage. This process reduces the accuracy of the single batch measurement, leading to larger errors, and the manual intervention also reduces production efficiency. This application provides an automatic batching device for accelerator production.

[0005] This application provides an automatic proportioning device for producing accelerators, which adopts the following technical solution: An automatic proportioning device for producing accelerators, comprising: A batching assembly includes a first support frame on which multiple raw material cylinders for storing different raw materials are arranged. A stirring unit is installed inside each raw material cylinder. A temporary storage cylinder is connected to the discharge end of each raw material cylinder. An adjustment unit is installed at the connection end between the raw material cylinder and the temporary storage cylinder to control the feeding speed of the raw materials. A feeding cylinder is installed outside the temporary storage cylinder. The temporary storage cylinder is installed inside the feeding cylinder via a connecting frame. Multiple weighing sensors are installed between the outer side of the temporary storage cylinder and the inner wall of the feeding cylinder. An opening and closing unit is installed at the bottom of the temporary storage cylinder, located above the discharge end of the feeding cylinder. A second support frame is installed below the first support frame. Multiple spiral conveying units are installed on the second support frame. The inlet end of each spiral conveying unit is connected to the discharge end of the feeding cylinder. Each spiral conveying unit corresponds to a feeding cylinder. A conveying assembly, which is connected to the discharge end of a plurality of spiral conveying units respectively; A control component is electrically connected to the dispensing component and the conveying component, respectively.

[0006] By adopting the above technical solution, the first support frame provides stable support for the batching components, multiple raw material cylinders enable the classified storage of different raw materials, and the stirring unit prevents raw material agglomeration to ensure smooth feeding, thereby reducing proportioning errors. The coordinated arrangement of the temporary storage cylinder and the feeding cylinder, combined with the weighing sensor between them, can accurately detect the weight of the raw materials in the temporary storage cylinder, providing data support for accurate proportioning. The adjustment unit can flexibly control the feeding speed of the raw materials as needed, and the opening and closing unit can control the falling of the raw materials in the temporary storage cylinder. The spiral conveying unit on the second support frame further conveys the raw materials transported by the feeding cylinder, and works with the conveying components to achieve centralized conveying of raw materials. The control component coordinates and controls all parts of the entire device, realizing the automation and precision of raw material proportioning in the quick-setting agent production process. Compared with the traditional manual intervention proportioning method, it significantly improves proportioning efficiency and accuracy. Optionally, the adjustment unit includes a first telescopic cylinder, a connecting rod, and an adjustment plate. The first telescopic cylinder is installed on the top of the temporary storage cylinder. The output end of the first telescopic cylinder is hinged to the connecting rod. The other end of the connecting rod is connected to a rotating rod. The rotating rod passes through the top of the temporary storage cylinder and extends into the interior of the temporary storage cylinder. The rotating rod is connected to the adjustment plate. The adjustment plate is rotatably disposed inside the communication end between the raw material cylinder and the temporary storage cylinder. By adopting the above technical solution, the first telescopic cylinder serves as the power source. Its telescopic movement is transmitted to the adjusting plate through the connecting rod and rotating rod, causing the adjusting plate to rotate inside the connecting end between the raw material cylinder and the temporary storage cylinder. This changes the size of the opening at the connecting end, thereby achieving precise control of the raw material feeding speed. This structure is easy to adjust and can adjust the feeding speed in a timely manner based on the information fed back by the weighing sensor, under the action of the control components, to ensure the accuracy of the weight of the raw material in the temporary storage cylinder. Optionally, the stirring unit includes a power source and a stirring shaft. The power source is installed on the top of the outside of the raw material cylinder and drives the stirring shaft. The stirring shaft is located inside the raw material cylinder and is provided with multiple stirring blades. A scraper is installed at the bottom of the stirring shaft through a connecting rod, and a gap is provided between the scraper and the inner wall of the raw material cylinder. By adopting the above technical solution, the power source drives the stirring shaft to rotate, and the stirring blades on the stirring shaft thoroughly stir the raw materials in the raw material cylinder, effectively preventing the raw materials from clumping due to prolonged storage. A gap is left between the scraper at the bottom of the stirring shaft and the inner wall of the raw material cylinder, allowing for the cleaning of any raw materials that may be adhering to the cylinder wall during the stirring process, reducing material waste and clumping, and ensuring the uniformity of the raw materials and smooth feeding. Optionally, the opening and closing unit includes a second telescopic cylinder, the fixed end of which is hinged to the outside of the temporary storage cylinder, and an opening and closing door is rotatably provided at the bottom of the temporary storage cylinder. The telescopic end of the second telescopic cylinder is hinged to the top of the opening and closing door to control the material in the temporary storage cylinder to be conveyed to the screw conveyor unit through the feeding cylinder. By adopting the above technical solution, the telescopic movement of the second telescopic cylinder can drive the opening and closing door at the bottom of the temporary storage cylinder to rotate, realizing the opening and closing of the bottom of the temporary storage cylinder. When the weight of the raw material in the temporary storage cylinder reaches the set value, the second telescopic cylinder actuates to open the opening and closing door, and the raw material enters the screw conveyor unit through the feeding cylinder under the action of gravity; after the raw material is conveyed, the opening and closing door closes, waiting for the next feeding. This structure has precise control and reliable operation, ensuring the orderly conveying of raw materials. Optionally, the conveying assembly includes a conveying unit and a lifting unit. The discharge end of the spiral conveying unit is connected to a conveying pipe, and the other ends of the plurality of conveying pipes are all connected to the top of the conveyor belt of the conveying unit. The output end of the conveying unit is connected to the input end of the lifting unit. The output end of the lifting unit is connected to a ball mill, and the output end of the ball mill is connected to a rotary kiln. By adopting the above technical solution, the raw materials conveyed by the spiral conveyor unit enter the conveyor belt of the conveying unit through the conveying pipe. The conveying unit concentrates the dispersed raw materials and conveys them to the lifting unit. The lifting unit lifts the raw materials to the ball mill. After being ground by the ball mill, the raw materials enter the rotary kiln for subsequent processing. This realizes the continuous conveying of raw materials from the completion of the proportioning to the subsequent processing, reduces the raw material loss and pollution in the intermediate links, and improves the continuity and efficiency of production. Optionally, the conveying unit includes a base frame, with a drive roller installed at one end and a driven roller installed at the other end. A conveyor belt is wound around the drive roller and the driven roller. A first drive source is installed on the outside of the base frame, and the output end of the first drive source drives and connects to the drive roller. Mounting plates are installed on both sides of the base frame, and the mounting plates are located below the conveyor belt. Brackets are installed on the mounting plates, and the brackets extend upward to both sides of the conveyor belt. An inclined guide wheel is installed at the other end of the bracket to make the conveyor belt conical. A protective cover is provided on the base frame.

[0007] By adopting the above technical solution, the first drive source drives the active roller to rotate, which, in conjunction with the driven roller, drives the conveyor belt to move, thereby realizing the conveying of raw materials. The mounting plates, brackets, and guide wheels on both sides of the base frame cooperate to make the conveyor belt concave, which facilitates the collection of raw materials from different positions on the conveyor belt towards the center and prevents raw materials from spilling. The protective cover can protect the raw materials during the conveying process, preventing external impurities from mixing in and raw material dust from being generated, thus ensuring the cleanliness of the raw materials. Optionally, the spiral conveying unit includes a conveying cylinder and a mounting frame. The mounting frame is disposed on the second support frame, and the conveying cylinder is mounted on the mounting frame. A second drive source is installed at one end of the conveying cylinder. A rotating shaft is rotatably disposed inside the conveying cylinder, and blades are spirally disposed on the rotating shaft. The output end of the second drive source drives and connects to the rotating shaft. One end of the conveying cylinder is connected to the discharge end of the feeding cylinder, and the other end is connected to the conveying unit. By adopting the above technical solution, the mounting frame securely installs the conveying cylinder onto the second support frame. The second drive source drives the rotating shaft to rotate, and the spiral blades on the rotating shaft rotate accordingly, pushing the raw material entering from the feed cylinder into the conveying unit. The spiral conveying method features stable conveying and high efficiency, effectively avoiding raw material blockage, ensuring the uniformity of raw material conveying, and providing a stable raw material supply for subsequent raw material collection and processing. Optionally, the top of the raw material cylinder is provided with a feed hole, and a feed cover is installed on the top of the raw material cylinder over the feed hole. By adopting the above technical solution, the feed hole facilitates the addition of raw materials into the raw material cylinder. After the raw materials are added, the feed cover can seal the feed hole to prevent external dust, impurities, etc. from entering the raw material cylinder and contaminating the raw materials. At the same time, it can also reduce the moisture absorption of the raw materials during storage and ensure the stability of the raw material quality.

[0008] In summary, this application includes at least one of the following beneficial technical effects: 1. This device achieves raw material storage, anti-caking, precise metering and controllable feeding through the batching component, completes the centralized transportation of raw materials through the conveying component, and coordinates the linkage of each link through the control component, ultimately realizing the automated and precise proportioning of multiple raw materials in the production process of quick-setting agent according to preset ratio; 2. The opening and closing unit is powered by the second telescopic cylinder and uses a hinged structure to drive the opening and closing door at the bottom of the temporary storage cylinder to rotate, so as to realize the precise opening and closing of the discharge port of the temporary storage cylinder. When the weight of the raw material in the temporary storage cylinder reaches the preset ratio requirement, the opening and closing door is opened in time to ensure that the raw material is put in according to the set weight, avoiding the ratio error caused by premature or delayed addition, thereby reducing the ratio error in the production of accelerator.

[0014] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0015] This application discloses an automatic proportioning device for producing accelerators, referring to... Figures 1-4 The automatic proportioning device for quick-setting agent production includes a batching component 1, a conveying component 2, and a control component. The batching component 1 includes a first support frame 11, on which multiple raw material cylinders 12 for storing different raw materials are arranged. A stirring unit 122 is installed inside the raw material cylinder 12. A temporary storage cylinder 13 is connected to the discharge end of the raw material cylinder 12. An adjustment unit 14 is installed at the communication end between the raw material cylinder 12 and the temporary storage cylinder 13 to control the feeding speed of the raw materials. A feeding cylinder 15 is installed outside the temporary storage cylinder 13. The temporary storage cylinder 13 is installed inside the feeding cylinder 15 through a connecting frame. The outer side of the temporary storage cylinder 13 is connected to the feeding cylinder 15. Multiple weighing sensors are installed between the inner walls of the material cylinder 15. An opening and closing unit 16 is installed at the bottom of the temporary storage cylinder 13. The opening and closing unit 16 is located above the discharge end of the material cylinder 15. A second support frame 17 is installed below the first support frame 11. Multiple spiral conveying units 18 are installed on the second support frame 17. The feed end of the spiral conveying unit 18 is connected to the discharge end of the material cylinder 15. The spiral conveying unit 18 corresponds to the material cylinder 15 one by one. The conveying component 2 is connected to the discharge ends of the multiple spiral conveying units 18 respectively. The control component is electrically connected to the batching component 1 and the conveying component 2 respectively.

[0016] In this device, the first support frame 11 of the batching component 1 provides a stable installation support for the raw material cylinder 12, temporary storage cylinder 13, and discharge cylinder 15, ensuring a stable path for the raw materials from storage to discharge. The raw material cylinder 12 is used to classify and store different raw materials required for the production of accelerators, providing independent storage space for the raw materials, facilitating the rapid retrieval of corresponding raw materials according to production needs, and ensuring the initial quality stability of the raw materials.

[0017] The stirring unit 122 continuously or intermittently stirs the raw materials in the raw material cylinder 12 to maintain the flowability of the raw materials. This effectively solves the problem of powders and other raw materials easily absorbing moisture and clumping, avoiding material blockage caused by clumping and bridging, ensuring uniform and smooth material feeding, and reducing proportioning errors caused by poor material flowability. The temporary storage cylinder 13 is used to temporarily receive the raw materials falling from the raw material cylinder 12 after stirring. It serves as a carrier for raw material metering and, in conjunction with a weighing sensor, achieves accurate measurement of the single feeding amount. This ensures that the weighing sensor only detects the weight of the raw material to be fed, improving metering accuracy.

[0018] The adjustment unit 14 changes the opening size by rotating the adjustment plate 143, thereby controlling the feeding speed of raw materials from the raw material cylinder 12 into the temporary storage cylinder 13. During operation, the feeding speed can be dynamically adjusted according to the weight data fed back by the weighing sensor, avoiding excessive feeding speed leading to over-measurement or excessively slow feeding affecting efficiency, and achieving precise control of feeding on demand.

[0019] The feeding cylinder 15 provides protection and a mounting base for the temporary storage cylinder 13, while guiding the raw materials falling from the temporary storage cylinder 13 into the spiral conveyor unit 18, forming a closed feeding channel. This prevents raw materials from spilling during the feeding process, reducing material waste and environmental pollution. Simultaneously, the feeding cylinder 15 provides a stable mounting platform for the weighing sensor. The weighing sensor can detect the weight of the raw materials in the temporary storage cylinder 13 in real time and transmit the weight signal to the control component, providing accurate weight data support for the raw material proportioning. The control component can adjust the feeding action of the adjustment unit 14 based on the difference between the preset proportioning parameters and the actual weight, achieving closed-loop weight control and significantly reducing proportioning errors.

[0020] The opening and closing unit 16 is used to control the opening and closing state of the bottom of the temporary storage cylinder 13. When the weight of the raw material in the temporary storage cylinder 13 reaches the set value, it opens to release the raw material into the feeding cylinder 15. After the feeding is completed, it closes to achieve precise start and stop of raw material feeding, avoid the chaos of the proportion caused by the raw material falling too early or too late, ensure that each raw material is fed in the preset order and weight, and improve the orderliness of the proportioning process.

[0021] The second support frame 17 supports the spiral conveying unit 18, maintaining the alignment between the spiral conveying unit 18 and the discharge end of the feeding cylinder 15, ensuring a smooth transition of raw materials from the feeding cylinder 15 to the spiral conveying unit 18. The spiral conveying unit 18 continuously and uniformly pushes the raw materials falling from the feeding cylinder 15 to the conveying component 2, realizing horizontal or inclined conveying of raw materials and solving the blockage problem in the conveying process of powder and other raw materials.

[0022] The conveying assembly 2 can receive raw materials conveyed by multiple spiral conveying units 18. The raw materials are collected by the conveying unit 21 of the conveying assembly 2, and the lifting unit 22 of the conveying assembly 2 transports the raw materials to subsequent processing equipment, such as the ball mill in the conveying assembly 2. The conveying assembly 2 realizes the centralized conveying of multiple raw materials, collects the dispersed metered raw materials and transfers them to the next process, reduces intermediate transfer links, and improves production continuity and efficiency.

[0023] The control component is used to receive the weight signal from the weighing sensor and adjust the operating status of the stirring unit 122, the adjustment unit 14, the opening and closing unit 16, the conveying component 2, etc. according to the preset program, so as to realize the automated collaborative work of each link of the device, replace the traditional manual operation, reduce the error caused by human factors, and at the same time, the proportioning parameters can be flexibly adjusted through program control to adapt to the production needs of different types of quick-setting agents.

[0024] The automatic proportioning device for accelerator production uses the batching component 1 to store, prevent caking, accurately measure and control the feeding of raw materials, the conveying component 2 to complete the centralized transportation of raw materials, and the control component to coordinate the linkage of each link, so as to realize the automated and precise proportioning of multiple raw materials in the accelerator production process according to the preset ratio.

[0025] Specifically, through a closed-loop control system consisting of independent metering in the temporary storage cylinder 13, real-time feedback from the weighing sensor, and dynamic adjustment by the adjustment unit 14, the mixing ratio error is controlled within an extremely low range. This solves the problem of insufficient accuracy in traditional manual mixing and ensures stable performance of the accelerator product. Automated feeding, metering, and conveying processes replace manual operation, reducing inefficiencies caused by manual intervention and avoiding downtime for cleaning due to raw material clumping and blockages, significantly improving production continuity and capacity.

[0026] refer to Figure 1 and Figure 2 The raw material cylinder 12 has a feed hole at its top, and a feed cover 121 is installed on the feed hole. The feed hole serves as a channel for raw materials to enter the raw material cylinder 12, providing an opening for replenishing raw materials into the raw material cylinder 12. This allows operators to easily add the raw materials required for the quick-setting agent production to the corresponding raw material cylinder 12, ensuring that there is always sufficient raw material in the raw material cylinder 12 for production proportioning. After the raw materials are added, the feed hole is sealed by the feed cover 121 to prevent external dust, impurities, etc., from entering the interior of the raw material cylinder 12, thus maintaining the raw materials in good condition.

[0027] refer to Figure 4The stirring unit 122 includes a power source 1221 and a stirring shaft 1222. The power source 1221 is installed on the top of the outside of the raw material cylinder 12 and drives the stirring shaft 1222. The stirring shaft 1222 is located inside the raw material cylinder 12 and is equipped with multiple stirring blades 1223. A scraper 1225 is installed at the bottom of the stirring shaft 1222 via a connecting rod 1224, and a gap is provided between the scraper 1225 and the inner wall of the raw material cylinder 12. The power source 1221 can convert electrical energy and other energy into mechanical energy to provide power output for the rotation of the stirring shaft 1222. The power source 1221 can be a servo motor, which will start, stop, and adjust the rotation speed according to the instructions of the control component, thereby flexibly adjusting the stirring intensity and frequency to meet the stirring needs of different raw materials. For example, the stirring frequency can be increased for raw materials that are prone to agglomeration. The stirring shaft 1222 can receive the power transmitted from the power source 1221 and drive the stirring blades 1223 and scraper 1225 on it to rotate synchronously, ensuring the continuous stirring operation. The stirring blades 1223 rotate together with the stirring shaft 1222 to stir and mix the quick-setting agent raw materials in the raw material cylinder 12, break up any lumps that may form in the raw materials, keep the raw materials in a loose state, and ensure that the raw materials have good fluidity. The connecting rod 1224 transmits the rotational power of the stirring shaft 1222 to the scraper 1225, so that the scraper 1225 can rotate synchronously with the stirring shaft 1222, thereby cleaning the inner wall of the raw material cylinder 12. A gap is left between the scraper 1225 and the inner wall of the raw material cylinder 12. As the stirring shaft 1222 rotates, it scrapes off the raw material adhering to the cylinder wall, preventing the raw material from accumulating and clumping, reducing waste, and ensuring the cleanliness of the inner wall of the raw material cylinder 12 to avoid residual raw material affecting the quality of subsequent raw materials. Simultaneously, the scraper 1225 prevents clumped raw material from clogging the feeding channel, improving the operational stability and continuity of the entire automatic proportioning device for accelerator production. refer to Figures 2-5The adjustment unit 14 includes a first telescopic cylinder 141, a connecting rod 142, and an adjustment plate 143. The first telescopic cylinder 141 is installed on the top of the temporary storage cylinder 13. The output end of the first telescopic cylinder 141 is hinged to the connecting rod 142, and the other end of the connecting rod 142 is connected to a rotating rod 144. The rotating rod 144 passes through the top of the temporary storage cylinder 13 and extends into the interior of the temporary storage cylinder 13. The rotating rod 144 is connected to the adjustment plate 143, which is rotatably positioned inside the communication end between the raw material cylinder 12 and the temporary storage cylinder 13. The first telescopic cylinder 141 converts the energy of compressed air into the mechanical energy of linear reciprocating motion, providing power output for the operation of the adjustment unit 14. The first telescopic cylinder 141 will extend and retract according to the instructions of the control component, changing the position of the output end, thereby flexibly adjusting the rotation amplitude of the adjustment plate 143 to meet the feeding speed control requirements of different raw materials. For example, when the raw material in the temporary storage cylinder 13 is close to the set weight, the extension and retraction amount can be reduced to reduce the feeding speed. The connecting rod 142 serves to transmit power and change the direction of force. The connecting rod 142 converts the linear motion of the first telescopic cylinder 141 into the rotational motion of the rotating rod 144, realizing the effective transmission of power from the first telescopic cylinder 141 to the rotating rod 144. Through the hinge structure, it adapts to the change of motion direction and ensures that the power of the first telescopic cylinder 141 can be stably transmitted to the rotating rod 144. The rotating rod 144 receives the rotational power transmitted by the connecting rod 142 and drives the adjusting plate 143 to rotate synchronously, thereby adjusting the size of the opening at the connection end between the raw material cylinder 12 and the temporary storage cylinder 13. Driven by the rotating rod 144, the adjusting plate 143 changes its relative angle with the connection end, thus adjusting the opening size and controlling the flow rate of raw material from the raw material cylinder 12 into the temporary storage cylinder 13. When the opening is larger, the feeding speed is faster; when the opening is smaller, the feeding speed is slower, achieving precise control of the raw material's entry speed into the temporary storage cylinder 13 and avoiding excessively fast or slow feeding that could affect metering accuracy. For quick-setting agent raw materials with different flowability, the feeding characteristics can be adapted by adjusting the opening size of the adjusting plate 143. refer to Figures 3-5 The opening and closing unit 16 includes a second telescopic cylinder 161. The fixed end of the second telescopic cylinder 161 is hinged to the outside of the temporary storage cylinder 13. The bottom of the temporary storage cylinder 13 is rotatably provided with an opening and closing door 162. The telescopic end of the second telescopic cylinder 161 is hinged to the top of the opening and closing door 162 to control the material in the temporary storage cylinder 13 to be conveyed to the screw conveyor unit 18 through the feeding cylinder 15.

[0028] The second telescopic cylinder 161 converts the energy of compressed air into mechanical energy for linear reciprocating motion, providing power output for the rotation of the opening and closing door 162. The second telescopic cylinder 161 performs telescopic movements according to the instructions of the control component, changing the position of the telescopic end, thereby controlling the rotation angle of the opening and closing door 162 to meet the timing and speed requirements of raw material feeding. For example, when the weight of the raw material in the temporary storage cylinder 13 reaches the set value, the telescopic end extends and drives the opening and closing door 162 to open. Driven by the second telescopic cylinder 161, the opening and closing gate 162 changes its relative angle with the bottom of the temporary storage cylinder 13, thereby controlling the opening and closing state of the temporary storage cylinder 13 and determining whether the raw material falls. When the opening and closing gate 162 is open, the raw material in the temporary storage cylinder 13 enters the screw conveyor unit 18 through the feeding cylinder 15 under the action of gravity; when the opening and closing gate 162 is closed, it prevents the raw material from falling, ensuring that the raw material is accurately metered in the temporary storage cylinder 13 before being fed. The hinge structure enables a rotatable connection between the fixed end of the second telescopic cylinder 161 and the temporary storage cylinder 13, and between the telescopic end and the opening / closing door 162. This allows for the adaptation to the angle changes during the extension and retraction of the second telescopic cylinder 161 and the position changes during the rotation of the opening / closing door 162, ensuring that the power of the second telescopic cylinder 161 can be stably and efficiently transmitted to the opening / closing door 162.

[0029] refer to Figures 1-6 The conveying assembly 2 includes a conveying unit 21 and a lifting unit 22. The discharge end of the spiral conveying unit 18 is connected to a conveying pipe 186. The other ends of multiple conveying pipes 186 are connected to the top of the conveyor belt 214 of the conveying unit 21. The output end of the conveying unit 21 is connected to the input end of the lifting unit 22. The output end of the lifting unit 22 is connected to a ball mill, and the output end of the ball mill is connected to a rotary kiln. The conveying unit 21 receives the raw materials conveyed by the multiple conveying pipes 186 via the conveyor belt 214, concentrating the dispersed raw materials before conveying them to the lifting unit 22, ensuring the continuity of raw material conveying. The conveying unit 21 can operate according to the instructions of the control assembly, maintaining a stable conveying speed.

[0030] The conveying pipe 186 serves as a channel for raw materials to travel from the spiral conveying unit 18 to the conveying unit 21, guiding the raw materials output from the spiral conveying unit 18 onto the conveyor belt 214, ensuring that the raw materials from each spiral conveying unit 18 accurately fall within the range of the conveyor belt 214 of the conveying unit 21. The conveyor belt 214 carries and transports the raw materials falling from the conveying pipe 186, transferring the raw materials from the input end to the output end of the conveying unit 21.

[0031] The lifting unit 22 receives the raw materials conveyed by the conveying unit 21 and uses a lifting mechanism to transport the raw materials from a lower position to a higher position in the ball mill. This overcomes the height difference and enables vertical or steep-angle conveying of the raw materials, ensuring that the raw materials can accurately enter the ball mill for further processing and reducing material loss during transport. In this application, the lifting unit 22 uses a chain bucket elevator, which has good sealing performance and effectively reduces material leakage.

[0032] The conveying unit 21 includes a base frame 211. A drive roller 212 is installed at one end of the base frame 211 and a driven roller 213 is installed at the other end. A conveyor belt 214 is wound around the drive roller 212 and the driven roller 213. A first drive source 215 is installed on the outside of the base frame 211. The output end of the first drive source 215 drives and connects to the drive roller 212. Mounting plates 216 are installed on both sides of the base frame 211. The mounting plates 216 are located below the conveyor belt 214. A bracket 217 is installed at both ends of the mounting plates 216. The bracket 217 extends upward to the side of the conveyor belt 214. An inclined guide wheel 218 is installed at the other end of the bracket 217 to make the conveyor belt 214 conical. A protective cover 219 is provided on the base frame 211.

[0033] The base frame 211 supports the drive roller 212, driven roller 213, conveyor belt 214, and other components, maintaining their relative positions. The first drive source 215 converts electrical energy into mechanical energy, driving the drive roller 212 to rotate and controlling the operating speed and start / stop status of the conveyor belt 214. By controlling the output speed of the first drive source 215, the conveying speed of the conveyor belt 214 can be flexibly adjusted to meet the conveying needs of different raw material quantities; for example, when there is a large amount of raw material, the speed can be increased to speed up the conveying. The first drive source 215 can be an electric motor, which is convenient and reliable to use. Driven by the first drive source 215, the drive roller 212 rotates actively, driving the conveyor belt 214 to circulate through friction. The conveyor belt 214 circulates under the drive of the drive roller 212, carrying the raw material falling from the conveying pipe 186 and conveying the raw material from the input end to the output end of the conveying unit 21. The driven roller 213 is arranged parallel to the drive roller 212 and rotates passively with the operation of the conveyor belt 214.

[0034] Mounting plate 216 provides a mounting base for bracket 217, which extends upward to both sides of conveyor belt 214, supporting guide wheels 218 and maintaining their tilt angle. The rigid connection between mounting plate 216 and bracket 217 ensures that guide wheels 218 can stably apply lateral force to conveyor belt 214, maintaining its tapered structure and providing stable structural support for material collection, thus preventing changes in the shape of conveyor belt 214 due to loosening of guide wheels 218. The guide wheel 218 contacts the side of the conveyor belt 214, applying a lateral guiding force to the conveyor belt 214, causing it to form a conical structure with a lower center and higher sides. This guides the raw material on the conveyor belt 214 to converge towards the center, preventing it from spilling from the sides, thus improving the material utilization rate and reducing waste. The protective cover 219 is installed on the base frame 211 and covers the area above the conveyor belt 214, forming a closed protective space. This prevents external impurities from entering the conveyor belt 214, avoiding contamination of the raw material by external dust and debris, and also prevents the spread of dust from the raw material on the conveyor belt 214, improving the operating environment. refer to Figures 2-4 The spiral conveying unit 18 includes a conveying cylinder 181 and a mounting frame 182. The mounting frame 182 is set on the second support frame 17. The conveying cylinder 181 is mounted on the mounting frame 182. A second drive source 183 is installed at one end of the conveying cylinder 181. A rotating shaft 184 is rotatably arranged inside the conveying cylinder 181. Blades 185 are spirally arranged on the rotating shaft 184. The output end of the second drive source 183 drives and connects to the rotating shaft 184. One end of the conveying cylinder 181 is connected to the discharge end of the feeding cylinder 15, and the other end is connected to the conveying unit 21.

[0035] The conveying cylinder 181 is connected at both ends to the discharge end of the feeding cylinder 15 and the conveying unit 21, respectively. It accommodates the rotating shaft 184 and the spiral blade 185, providing a closed space for raw material conveying, preventing raw material spillage and dust, and ensuring that the raw material can be stably conveyed to the conveying unit 21 along a fixed path. The mounting bracket 182 is used to fix the conveying cylinder 181, maintain the alignment relationship between the conveying cylinder 181 and the feeding cylinder 15 and the conveying unit 21, and ensure a smooth transition of raw material from the feeding cylinder 15 to the conveying unit 21. The second drive source 183 converts electrical energy into mechanical energy, driving the rotating shaft 184 and the helical blades 185 to rotate, providing power for raw material conveying. By controlling the rotation speed of the second drive source 183, the conveying speed of the raw materials can be flexibly adjusted to meet the conveying needs of different raw material quantities. For example, when a large amount of raw material is added to the temporary storage cylinder 13, the rotation speed can be increased to accelerate conveying. The rotating shaft 184 carries the helical blades 185 and drives them to rotate synchronously. The helical surface of the blades 185 pushes the raw materials in the conveying cylinder 181 to move along the conveying direction, achieving continuous conveying of the raw materials. The helical conveying method is highly adaptable to powdery raw materials that are prone to agglomeration and have poor flowability. The rotation of the helical blades 185 can play a certain role in stirring and loosening the raw materials, reducing adhesion and blockage within the conveying cylinder 181, and improving conveying reliability. The implementation process of an automatic proportioning device for producing accelerators according to an embodiment of this application is as follows: First, the operator adds various raw materials required for the quick-setting agent production to different raw material cylinders 12 through the feed hole at the top of the raw material cylinder 12, and then covers the feed cover 121 to prevent the raw materials from getting damp or contaminated. After the control component is started, the stirring unit 122 inside the raw material cylinder 12 works, that is, the power source 1221 drives the stirring shaft 1222 to rotate, the stirring blades 1223 continuously stir the raw materials to prevent agglomeration, and the bottom scraper 1225 cleans the raw materials adhering to the cylinder wall to ensure that the raw materials maintain good fluidity. When a mixing operation is required, the control component sends a command to the adjustment unit 14 of the corresponding raw material cylinder 12 according to the preset raw material mixing parameters. The first telescopic cylinder 141 actuates, driving the adjustment plate 143 to rotate at the connection end between the raw material cylinder 12 and the temporary storage cylinder 13 via the connecting rod 142 and the rotating rod 144, opening the feeding channel and adjusting the opening size to control the feeding speed. The raw material falls from the raw material cylinder 12 into the temporary storage cylinder 13. At this time, the weighing sensor between the outer side of the temporary storage cylinder 13 and the inner wall of the feeding cylinder 15 detects the weight of the raw material in the temporary storage cylinder 13 in real time and feeds the data back to the control component. When the weight of the raw material approaches the set value, the control component adjusts the adjustment unit 14 to reduce the opening and decrease the feeding speed; when the set weight is reached, the adjustment unit 14 closes the feeding channel, completing a single raw material metering. After metering is completed, the control component instructs the opening and closing unit 16 to operate: the extension end of the second telescopic cylinder 161 extends, causing the opening and closing door 162 at the bottom of the temporary storage cylinder 13 to rotate and open. The raw material in the temporary storage cylinder 13 falls into the conveying cylinder 181 of the screw conveyor unit 18 under the action of gravity through the feeding cylinder 15. After the opening and closing door 162 closes, it waits for the next metering cycle.

[0036] The spiral conveyor unit 18 starts working: the second drive source 183 drives the rotating shaft 184 and the spiral blades 185 to rotate inside the conveying cylinder 181. The blades 185 push the raw material along the conveying cylinder 181 towards the conveying unit 21. The mounting frame 182 stably fixes the conveying cylinder 181 on the second support frame 17 to ensure accurate docking of the raw material from the discharge cylinder 15 to the conveying unit 21 and avoid spillage. Multiple spiral conveyor units 18 respectively convey different raw materials to the conveyor belt 214 of the conveying unit 21, and guide the raw materials onto the conveyor belt 214 through the conveying pipe 186. The first drive source 215 of the conveying unit 21 drives the active roller 212 to rotate, which in turn drives the conveyor belt 214. The driven roller 213 cooperates to maintain the tension and stability of the conveyor belt 214. The guide wheels 218 on both sides of the conveyor belt 214 make the conveyor belt 214 conical, which gathers the scattered raw materials to the center. The protective cover 219 on the base frame 211 covers the conveyor belt 214 to prevent raw material dust and external pollution. The gathered raw materials are conveyed by the conveyor belt 214 to the output end of the conveying unit 21 and enter the lifting unit 22.

[0037] Lifting unit 22 lifts the raw materials to the ball mill, where they are ground and then fed into the rotary kiln for further processing, completing the entire production process from raw material proportioning to deep processing. Throughout the process, the control components coordinate the actions of each unit, adjusting the equipment's operating status in real time through sensor feedback data to ensure proportioning accuracy and production continuity, thereby achieving automated and precise operation in the production of accelerators.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
