[0002] In the industrial silicon production process, the precise proportioning of raw materials is crucial. Traditional raw material proportioning and mixing devices have some shortcomings. On the one hand, in the feeding link, the common feeding method is difficult to accurately control the flow and addition amount of raw materials. For example, some devices use simple gravity feeding or screw conveying, which cannot adjust the feeding speed in a timely manner according to real-time weight feedback, resulting in excessive or insufficient addition of raw materials, affecting the proportioning accuracy. On the other hand, in the weighing and adjusting stage, when the weight approaches the preset value, there is a lack of effective dynamic compensation mechanism. Once the first weighing does not reach the preset value, it can only be adjusted by manual intervention or simple secondary feeding, which is not only low in efficiency but also has large human error, and it is difficult to meet the high accuracy requirements of industrial silicon production for raw material proportioning.

[0022] Control display module 101 is set up in installation base plate 1 one side surface, and corresponding lifting mechanism and weighing mechanism are electrically connected by wire mode to carry out data transmission. The operator can carry out a variety of operations. For example, the target weight value of each raw material can be preset according to production demand, and the weight data measured by the weighing mechanism in real time is fed back to the control display module 101. When the weighing value reaches 90% of the target value (this threshold value can be flexibly set by the control display module 101), the control display module 101 sends a first deceleration instruction to the lifting mechanism; when the weighing value reaches 98%, a second deceleration instruction is sent. At the same time, the control display module 101 can also display the working state of each feeding channel 2 in real time, including whether the raw material is being transported, whether the weighing is completed, and other information, and supports formula storage, which is convenient for quick calling under different production demands. Through the intelligent control of the control display module 101, the convenience and accuracy of operation are improved. The operator does not need to operate and observe each part of the equipment separately, and all control and monitoring work can be completed on one interface. The hierarchical early warning and dynamic compensation control effectively reduces manual intervention, reduces human error, and further improves the proportioning accuracy. At the same time, the fault diagnosis function can be set, the data such as the raw material passing time is analyzed, whether the feeding pipe 201 is blocked is automatically identified, and the alarm information is displayed on the interface in time, which is convenient for the operator to handle in time, reduces the equipment downtime, and improves the production efficiency.

[0023] Please refer to Figure 2 And Figure 3Each feeding pipe 201 is in communication with a feeding hopper 202 at the top end.

[0024] The feeding hopper 202 is funnel-shaped, with a large end for receiving raw materials and a small end in communication with the top end of the feeding pipe 201. The inner wall is coated with a Teflon coating to reduce the friction between the raw materials and the inner wall of the feeding hopper 202.

[0025] Further, the top end of each blocking block 204 is provided with a slope that is consistent with the inclination direction and angle of the inner wall of the bottom and top of the feeding pipe 201.

[0026] The slope at the top end of the blocking block 204 is consistent with the inclination direction and angle of the inner wall of the bottom and top of the feeding pipe 201. In the initial state, when the blocking block 204 is located in the installation slot 203, the inner wall of the bottom of the feeding pipe 201 forms a continuous and smooth plane, and the raw materials can slide down the feeding pipe 201 without obstruction. When it is necessary to control the flow of raw materials, the blocking block 204 rises under the action of the lifting mechanism, and the slope forms a variable gap with the inner wall of the top of the feeding pipe 201. As the height of the blocking block 204 increases, the gap gradually decreases, and the flow rate of the raw materials gradually decreases. The flow of raw materials can be calculated and controlled to achieve flow regulation. The slope ensures the smoothness of the raw materials during normal transportation, reducing the jamming and residue of the raw materials at the bottom of the feeding pipe 201. During the flow control stage, the variable gap formed by the slope can achieve linear regulation of the flow of raw materials, and compared with other blocking structures, it can more accurately control the amount of raw materials added, improve the matching precision, and provide more accurate raw material matching guarantee for industrial silicon production.

[0027] Further, each lifting mechanism includes a threaded groove 205 opened on the bottom surface of the corresponding blocking block 204, each threaded groove 205 is threadedly connected with an adjusting screw 206, the bottom end of each adjusting screw 206 is fixedly connected with one end of the output shaft of a corresponding drive motor 207, and each drive motor 207 is fixedly installed on the bottom surface of the installation base plate 1 and its output shaft extends to the other side through a through hole and is connected with the corresponding adjusting screw 206.

[0028] The lifting mechanism drives the vertical movement of the material blocking block 204 through the driving motor 207 driving the adjusting screw 206. The driving motor 207 is fixedly installed on the bottom surface of the mounting base plate 1, and its output shaft extends to the other side of the mounting base plate 1 through a through hole and is fixedly connected with the bottom end of the adjusting screw 206. The adjusting screw 206 is threadedly connected with the threaded groove hole 205 at the bottom of the material blocking block 204. When the driving motor 207 receives the instruction issued by the control display module 101, the output shaft thereof rotates to drive the adjusting screw 206 to rotate. Due to the threaded cooperation between the adjusting screw 206 and the threaded groove hole 205, the material blocking block 204 can be lifted or lowered in the vertical direction in the mounting slot 203. Each material blocking block 204 can also be provided with a displacement sensor, which can feed back the height data of the material blocking block 204 to the control display module 101 in real time, so as to form a closed-loop control and ensure the positioning accuracy of the material blocking block 204.

[0029] Please refer to Figure 2 and Figure 4 The receiving box 3 is provided with a plurality of communication openings 301 corresponding to each feeding pipe 201 on the side surface thereof facing the feeding pipes 201, and a plurality of mounting grooves 302 corresponding in position and number to the communication openings 301 are formed on the bottom surface of the receiving box 3. A weighing receiving hopper 303 is rotatably installed in each mounting groove 302 through a connecting member. A weighing sensor is embedded in the inner wall at the bottom of each weighing receiving hopper 303. An extension driving member 304 is arranged below each mounting groove 302, and the movable end of each extension driving member 304 is movably connected with the side surface of the corresponding weighing receiving hopper 303 to drive the weighing receiving hopper 303 to overturn.

[0030] The receiving box 3 is provided with a plurality of communication openings 301 on the side surface thereof facing the feeding pipes 201, and the low end of each feeding pipe 201 is in communication with the corresponding communication opening 301. The raw materials fall into the weighing receiving hopper 303 in the receiving box 3 through the communication opening 301. The weighing receiving hopper 303 is made of stainless steel, and a weighing sensor is embedded in the inner wall at the bottom thereof. The weighing sensor can accurately measure the weight of the raw materials falling therein. When the weighing is completed and the materials need to be unloaded, the extension driving member 304 arranged below the mounting groove 302 is started. The extension driving member 304 can be a pneumatic cylinder or a hydraulic cylinder, and the piston rod thereof can be rotatably connected or slidably hinged according to the actual position distribution to drive the weighing receiving hopper 303 to overturn.

[0031] Further, each extension driving member 304 is rotatably installed between two connecting brackets 305, and one end of each connecting bracket 305 is fixedly connected with the side surface of the mounting base plate 1.

[0032] The telescopic driving member 304 is connected with the mounting base plate 1 through the connecting supports 305, and meanwhile, in order to ensure that the weighing receiving hopper 303 does not interfere with the movement when being driven to overturn, the telescopic driving member 304 is rotatably mounted between the corresponding two connecting supports 305, so that the telescopic driving member 304 can be deflected by a corresponding angle to match the movement of the weighing receiving hopper 303, thereby ensuring the stability of discharging the materials to the stirring and mixing device.

[0033] Working principle: The raw materials are injected from the feeding hopper 202 and flow into the inclined feeding pipe 201 by gravity. The feeding pipe 201 is uniformly provided with the mounting slots 203 on the inner wall of the bottom. In the initial state, the top end of the material blocking block 204 is located in the slot, and the bottom of the feeding pipe 201 is a complete plane, so that the raw materials can smoothly slide to the weighing receiving hopper 303 in the receiving box 3. The weighing mechanism monitors the weight of the raw materials in real time, and the data is fed back to the control display module 101. When the weight approaches the preset value (such as 90%), the control display module 101 sends an instruction to the lifting mechanism, and the driving motor 207 drives the adjusting screw 206 to rotate, so that the material blocking block 204 rises, and the inclined surface and the bottom of the feeding pipe 201 form a variable gap, thereby reducing the flow rate of the raw materials. If the weight is still insufficient after being completely blocked, the system starts to open the material blocking block 204 from the end close to the weighing mechanism to supplement the raw materials in a small amount in sequence until the weight is consistent with the preset value. After the weight of each raw material is determined, the telescopic driving member 304 is started to push the weighing receiving hopper 303 to overturn, so that the raw materials are poured into the stirring and mixing device through the discharging connecting part 4, the precise proportioning and conveying process is completed, and the precise proportioning of the raw materials for industrial silicon production is realized.

[0034] It should be noted that the specific type and specification of the driving motor 207, the telescopic driving member 304, the weighing sensor, the control display module 101 and the stirring and mixing device need to be determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the art, so it will not be described in detail.

[0035] The power supply and principle of the driving motor 207, the telescopic driving member 304, the weighing sensor, the control display module 101 and the stirring and mixing device are clear to those skilled in the art, and will not be described in detail here.

[0036] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
