Description

Technical Field

[0001] This invention belongs to the field of metallurgical industrial automation and equipment technology, and specifically relates to a smelting batching silo unblocking device and unblocking control method. Background Technology

[0002] In the metal smelting production process, the batching silo is a crucial piece of equipment connecting raw material storage with subsequent smelting processes. Its main function is to precisely mix various raw materials such as ore, coke, and flux according to a preset ratio and stably transport them to the next production stage. Because smelting raw materials often have characteristics such as fine particles, uneven moisture content, and strong viscosity, blockages such as "arching," "hanging," and "bridging" can easily occur in areas like the conical section of the silo and the discharge port during the feeding process. Once a blockage occurs, it directly leads to interruption of material flow and imbalance in the batching ratio. This not only causes production downtime and reduces production efficiency, but in severe cases, excessive accumulation of blocked material can even cause abnormal pressure on the silo, posing a safety hazard to the equipment.

[0003] Currently, common methods for preventing and clearing blockages in batching silos in the metallurgical industry mainly include silo wall vibrators, pneumatic arch-breaking devices, rotary scrapers, and manual cleaning. Silo wall vibrators use high-frequency vibration to dislodge blockage material, but this method is passive, unable to detect blockage status in real time, requiring continuous operation or intermittent blind starts, resulting in high energy consumption. Furthermore, long-term high-frequency vibration can cause fatigue damage to the silo structure, shortening equipment lifespan. Pneumatic arch-breaking devices use high-pressure gas to impact and break up material arches, but their effective range is limited, and the clearing effect is unstable. The instantaneous impact of high-pressure gas can easily cause material splashing and secondary arching, and there are also problems with inaccurate blockage identification and blind operation. Rotary scrapers have fixed structural dimensions, requiring separate design for different sizes and shapes of batching silos, and cannot be adapted to different silos by adjusting their own dimensions, increasing manufacturing and operating costs. Manual cleaning is not only labor-intensive and inefficient, but also poses safety risks such as working at heights and material falls, failing to meet the automated and intelligent production needs of modern metallurgical industries.

[0004] Furthermore, in terms of blockage monitoring, existing technologies mostly employ simple level gauges and pressure sensors. Level gauges can only monitor the overall liquid level of the material within the silo, and cannot accurately determine the material flow status in a localized area at the discharge port, making it difficult to provide early warnings of minor local blockages. Pressure sensors detect changes in pressure within the silo to determine the blockage situation, but they are easily affected by factors such as material gravity and viscosity, resulting in low monitoring accuracy and delayed warnings. Warnings are often only issued after blockages have already occurred and affected material flow, failing to achieve early prediction and proactive prevention.

[0005] In summary, existing methods for clearing blockages in batching silos suffer from drawbacks such as weak proactive prevention capabilities, unstable clearing effects, high energy consumption, significant equipment damage, and high manufacturing and operating costs. Blockage monitoring methods also suffer from low accuracy, delayed early warnings, and an inability to accurately identify localized blockages, making them ill-suited to the efficient, stable, intelligent, and safe production requirements of modern metal smelting industries for batching processes. Therefore, there is an urgent need to develop an intelligent blockage clearing system capable of real-time and accurate monitoring of material flow conditions, providing early warnings of blockages, and possessing universality, proactive, efficient, low-disturbance, and low-energy-consumption capabilities to address the shortcomings of existing technologies.

Detailed Implementation

[0023] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0024] It should be noted that when a component is referred to as "fixed to," "placed," "equipped with," "provided with," "arranged on," or "connected to" another component, it can be directly on the other component or may have an intervening component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or may have an intervening component present.

[0025] The technical solution of the present invention is illustrated below through specific embodiments. It should be understood that the one or more steps mentioned in the present invention do not preclude the existence of other methods and steps before or after the combined steps, or that other methods and steps may be inserted between these explicitly mentioned steps. It should also be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Unless otherwise stated, the numbering of each method step is only for the purpose of identifying each method step, and not for limiting the order of each method or limiting the scope of the present invention. Changes or adjustments to their relative relationships, without substantial changes to the technical content, can also be considered as within the scope of the present invention.

[0026] The raw materials and instruments used in the examples are not subject to any specific restrictions on their source; they can be purchased from the market or prepared according to conventional methods known to those skilled in the art.

[0027] like Figures 1 to 10 As shown, the first aspect of the present invention provides a device for unclogging a smelting batching bin 5, such as... Figure 1 As shown, it includes: scraping unit 1, rotating unit 2, driving unit 3, monitoring unit, and control unit (not shown in the figure).

[0028] The scraping unit 1 is located inside the mixing hopper 5 and is used to scrape off the material adhering to the inner wall of the mixing hopper 5.

[0029] Specifically, such as Figure 2 As shown, the batching silo 5 adopts the structure of a batching silo 5 in the prior art, and there are no restrictions here. However, it should be noted that the batching silo 5 should typically have a straight cylindrical section 501 and a conical section 502. During the material's descent, due to its own viscosity and other factors, material is prone to adhering to the inner wall of the conical section 502. As the amount of adhered material increases, the discharge space gradually decreases, and in severe cases, the discharge port may be completely blocked. Therefore, the scraping unit 1 should be installed on the inner wall of the conical section 502 of the batching silo 5.

[0030] In this embodiment, the rotating unit 2 is disposed outside the discharge port of the mixing hopper 5, and includes a rotating part 201 and a fixing part 202. The scraping unit 1 is adjustablely disposed on the rotating part 201. The fixing part 202 is detachably connected to the outer wall of the mixing hopper 5.

[0031] Specifically, by detachably connecting the fixing part 202 to the outer wall of the mixing bin 5, it is possible to add and modify the original mixing bin 5, avoiding the elimination of the original mixing bin 5, thereby saving modification costs for enterprise users.

[0032] In this embodiment, the driving unit 3 is connected to the rotating part 201 and is used to drive the rotating part 201 to rotate.

[0033] In this embodiment, the monitoring unit is set on the rotating unit 2 and is used to collect cross-sectional shape data of the material discharged from the outlet of the batching bin 5 in real time.

[0034] In this embodiment, the control unit is electrically connected to the monitoring unit and the drive unit 3 respectively, and is used to acquire cross-sectional shape data and control the operation of the drive unit 3.

[0035] Specifically, the control unit can be a PLC (Programmable Logic Controller), a circuit including at least one processor, a circuit including at least one microcontroller, or a combination of multiple circuits or chips, as long as it can achieve the corresponding function. It is understood that, for those skilled in the art, the control circuit can also be a common circuit composed of amplifiers, comparators, transistors, MOSFETs, etc., implemented purely in hardware. The control unit can be located in the power distribution box of drive unit 3, or in other locations; there are no restrictions here.

[0036] Specifically, the control unit and the monitoring unit can be connected wirelessly or by other electrical means; there are no restrictions here.

[0037] In some implementations, such as Figure 2 , Figure 3 As shown, the number of scraping units 1 is not less than 2, preferably 2, but 3 to 4 can also be used, and they are evenly arranged in the circumferential direction.

[0038] In this embodiment, the scraping unit 1 includes a scraping part 101, a scraping connecting part 102, and a scraping adjustment part 103.

[0039] The scraping part 101 is hinged to one end of the scraping connecting part 102 and extends into the filling bin 5.

[0040] Specifically, a hinge structure can be used for connection so that the scraping part 101 can swing in the vertical plane with the hinge 104 as the center.

[0041] Specifically, the scraping connection 102 can adopt a linkage structure, with one end connected to the scraping part 101 extending into the mixing hopper 5.

[0042] In this embodiment, the scraping part 101 can move along the extending direction of the scraping connection part 102 and can be positioned at the corresponding moving position.

[0043] Specifically, an adjustment and positioning mechanism can be provided between the scraping part 101 and the scraping connecting part 102, such as a gear-rack, lead screw-nut, pin-hole-pin, or worm gear-worm mechanism. The present invention preferably uses a pin-hole-pin structure; specifically, such as... Figure 4 As shown, the scraping connection 102 can be configured as two rods that are fitted together. The scraping part 101 is hinged to the upper rod 1021 via a hinge 104. A pin 1024 with a return spring is provided on the upper rod 1021, and multiple pin holes 1023 are provided on the lower rod 1022. When the height of the scraping part 101 needs to be adjusted, the upper rod 1021 can be moved so that the pin holes 1023 at different positions are aligned with the pin 1024 to achieve height adjustment. After releasing the pin 1024, the pin 1024 is inserted into the pin hole 1023 to achieve positioning.

[0044] In this embodiment, as Figure 5 As shown, the scraping section 101 is transverse (referring to...) Figure 5 Scraping blades 1011 are provided on both sides (left and right directions).

[0045] Specifically, the edge of the scraping blade 1011 can be set as a relatively sharp blade-like structure, and the scraping blades 1011 on both sides extend obliquely towards the inner wall, so that the scraping part 101 forms a ridge-like structure with a central protrusion.

[0046] In this embodiment, the scraping section 101 is longitudinal (referring to...) Figure 5 Both ends of the feed hopper 5 are provided with scraping support parts 1012 in the vertical direction; the scraping support parts 1012 abut against the inner wall of the feed hopper 5.

[0047] Specifically, the scraping support 1012 can adopt a bearing structure; the scraping part 101 is provided with mounting shafts at both ends, and the inner ring of the bearing is connected to the mounting shaft; the bearing diameter should be slightly larger than the height of the scraping part 101 (the distance from the ridge to the cutting edge) so that the bearing can abut against the inner wall and form a certain gap between the edges of the scraping cutting edges 1011 on both sides and the inner wall; the gap can be set according to the specific situation, and in this invention it is set to 5mm~15mm.

[0048] In this embodiment, the other end of the scraping connection 102 is adjustablely connected to the scraping adjustment part 103 to change the tilt angle of the scraping connection 102.

[0049] Specifically, the scraping adjustment part 103 can adopt existing structures such as toothed plate-ratchet, sector groove-bolt, friction disc-positioning part, or worm gear-locking part; no limitation is made here. The present invention preferably adopts a worm gear-locking part structure; specifically, such as... Figure 6As shown, an adjusting turbine 1031 is fixedly installed at one end of the scraping connecting part 102 connected to the scraping adjusting part 103. The center of the adjusting turbine 1031 is connected to the fixed part (such as a support housing or support plate) of the scraping adjusting part 103 via a rotating shaft. A rotatable adjusting worm 1032 is installed inside the scraping adjusting part 103. Both ends of the adjusting worm 1032 are supported by bearings on the fixed part (such as a support housing or support plate) of the scraping adjusting part 103, and the adjusting worm 1032 and the adjusting turbine 1031 mesh with each other. One end of the adjusting worm is equipped with a handwheel or gear, which can be driven to rotate manually or electrically by adding a motor. The adjusting worm drives the adjusting turbine to rotate, which in turn drives the scraping connecting part 102 to swing. A locking nut (not shown in the figure) can be installed at one end of the adjusting worm. After tightening, the adjusting worm can be locked to prevent the scraping connecting part 102 from loosening.

[0050] In this embodiment, the scraping adjustment part 103 and the rotating part 201 are adjustablely connected, and can move along the radial direction of the rotating part 201 and be positioned at the corresponding position during movement.

[0051] Specifically, a sliding groove-rail, ball-screw, gear-rack, or other structure can be provided between the scraping adjustment part 103 and the rotating part 201 to achieve movement adjustment; no specific structural limitations are specified here. The present invention preferably uses a sliding groove-rail structure; specifically, such as... Figure 3 As shown, a groove 1034 is provided on the fixed part of the scraping adjustment part 103 (such as a support housing or support plate), and a slide rail 1033 is provided at the corresponding position on the rotating part 201 (such as a support seat provided on the upper end face or side end face of the rotating part 201, and a slide rail provided on the support seat). The slide rail 1033 and the groove 1034 are connected to each other, so that the entire scraping adjustment part 103 can move radially on the rotating part 201. A screw and nut mechanism can also be provided, and a handwheel or gear can be provided on the screw to realize manual or electric drive adjustment. A threaded through hole (not shown in the figure) is provided on the side of the groove 1034. By inserting a locking screw (not shown in the figure) through the threaded through hole and tightening it, the slide rail 1033 can be locked in the corresponding position to realize the positioning of the scraping adjustment part 103.

[0052] In specific implementation, one end of the scraping part 101 is hinged to the scraping connection part 102, so that the scraping part 101 can swing at a certain angle in the vertical plane to adapt to the inclination angle of the inner wall of the cone section 502 of different batching bins, and has better adaptability. The scraping part 101 can move along the extension direction of the scraping connection part 102 and can be positioned at the corresponding position, so that the height of the scraping part 101 can be adjusted to adapt to the cone section 502 of different lengths in different batching bins 5. For example, one scraping part 101 can be raised and the other scraping part 101 can be lowered, so that the entire length of the cone section 502 can be covered, and a more comprehensive scraping range can be achieved. The scraping section 101 is provided with scraping blades 1011 on both sides of the horizontal (referring to the direction of rotation) to meet the requirement that the scraping unit 1 can perform scraping operations in both forward and reverse rotation. The blades are made with a relatively sharp structure, which can more effectively scrape off the material adhering to the inner wall. The blades maintain a certain gap with the inner wall, which can prevent the blades from directly contacting the inner wall and causing mutual wear while effectively scraping off the material.

[0053] Scraping support parts 1012 are provided at both ends of the scraping part 101 in the longitudinal direction. The outer ring of the scraping support part 1012 abuts against the inner wall of the mixing bin 5, which can provide support for the scraping part 101, maintain the gap with the inner wall, and reduce the friction. The scraping adjustment part 103 and the rotating part 201 are adjustablely connected, so that the overall diameter of the scraping unit 1 can be adjusted to adapt to the feeding bins 5 of different diameters. At the same time, in cooperation with the scraping adjustment part 103, it can adapt to more feeding bins 5 of different sizes and shapes, further improving the adaptability of the device. One end of the scraping connection 102 is adjustablely connected to the scraping adjustment part 103, allowing the inclination angle of the scraping connection 102 to be adjusted. This enables it to adapt to different shapes and sizes of batching bins 5, and also allows for adjustments during the installation of this unblocking device. Figure 7 As shown, first, the scraping connection 102 is adjusted inward so that the scraping unit 1 can be inserted into the batching bin 5 as a whole through the discharge port of the batching bin 5. Then, the scraping connection 102 is swung outward so that the scraping part 101 abuts against the inner wall of the batching bin 5. This makes it easier to add this device to the original batching bin 5, avoiding the need to disassemble the entire batching bin 5 during the addition process, which would increase the cost and complexity of the modification.

[0054] In some implementations, such as Figure 2 As shown, the fixing part 202 is provided with a plurality of clamping mechanisms 203 arranged symmetrically along the central axis of the mixing bin 5. Two to six clamping mechanisms can be provided, and four are preferred in this invention. Each clamping mechanism 203 includes a clamping shoe 2031 and a clamping adjustment part 2032.

[0055] The clamping hoof 2031 is located at one end of the clamping adjustment part 2032 near the feed hopper 5, and the other end away from the clamping adjustment part 2032 is pressed against the outer wall of the feed hopper 5.

[0056] Specifically, the clamping hoof 2031 can be connected to the clamping adjustment part 2032 by a hinge structure or a fixed method. A material layer with high friction can be set on the end face near the feeding bin 5 to increase the stability of the overall device.

[0057] In this embodiment, the clamping adjustment part 2032 and the fixing part 202 are adjustablely connected, and can move along the radial direction of the fixing part 202 and be positioned at the corresponding position of the movement.

[0058] Specifically, a support frame 204 can be provided on the upper or side end face of the fixing part 202, and the clamping adjustment part 2032 can be fixedly installed on the support frame 204 so that the clamping shoe 2031 can be pressed against the outer wall of the straight section 501 of the batching bin 5.

[0059] Specifically, if the outer wall of the batching bin 5 is relatively smooth, the clamping shoe 2031 can be fixedly installed on the outer wall of the batching bin 5 by means of screws, welding or rivets, but this will affect the structural integrity of the batching bin 5.

[0060] Specifically, the clamping adjustment part 2032 can adopt a slide rail-slide rail, nut-lead screw, gear-rack, or other structures to achieve movement adjustment; no specific structural limitations are specified here. The present invention preferably uses a nut-lead screw structure (not shown in the figure); specifically, such as... Figure 2 As shown, the lead screw is located in the fixed part of the clamping adjustment section 2032 (such as a support housing or support plate), supported at both ends by bearings, and has a handwheel or gear at one end, which can be driven to rotate manually or electrically by adding a motor. A nut is fitted onto the lead screw and engages with it. The nut has a connecting part that can be connected to the clamping shoe 2031 via a hinge or fixing method. Rotating the lead screw causes the nut to move axially, thereby pressing the clamping shoe 2031 against the outer wall of the batching bin 5. A locking nut 2033 is fitted onto one end of the lead screw to lock the clamping adjustment section 2032, preventing the clamping shoe 2031 from loosening.

[0061] In specific implementation, a clamping mechanism 203 is provided, which can hoist and fix the entire device to the batching bin 5 when the device is installed, providing stable support for the device; a clamping adjustment part 2032 is provided, which can adjust the overall diameter of the clamping mechanism 203 to adapt to batching bins 5 of different sizes, further improving the adaptability of the device; by using the clamping shoe 2031 to press against the outer wall of the batching bin 5, the device can be installed without damaging the overall integrity of the batching bin 5, and it is easy to disassemble, maintain and replace.

[0062] In some implementations, such as Figure 2 As shown, both the fixing part 202 and the rotating part 201 are annular structures. The fixing part 202 is sleeved on the periphery of the rotating part 201, and a rolling part 205 is provided between the fixing part 202 and the rotating part 201.

[0063] Specifically, the rotating unit 2 can adopt a bearing structure, preferably a radial thrust double-row roller bearing in the prior art, with the inner ring being the rotating part 201 and the outer ring being the fixed part 202 (they can also be interchanged, but it is necessary to avoid the problem of motion interference of other parts); the rolling part 205 is preferably a double-row frustum roller (tapered roller) structure, which has greater support strength.

[0064] In practice, the hollow bearing structure can completely avoid the discharge port of the batching silo, thus avoiding obstruction of the falling material flow and making the material discharge smoother, providing a guarantee for smelting production.

[0065] In some implementations, such as Figure 2 , Figure 8 As shown, the drive unit 3 includes a drive section 301 and a transmission section 302.

[0066] The drive unit 301 is horizontally mounted on the fixed unit 202, and its power output end is connected to the power input end of the transmission unit 302.

[0067] Specifically, the drive unit 301 can adopt a stepper motor or servo motor structure, and the power output end is the output shaft of the motor.

[0068] In this embodiment, the power output end of the transmission unit 302 is connected to the rotating unit 201.

[0069] Specifically, the transmission unit 302 can adopt a structure such as a worm gear, gear drive, or belt drive. For example... Figure 8 As shown, the present invention preferably uses a worm gear structure, with the power input end being the worm and the power output end being the turbine. Specifically, a drive turbine 3021 is provided on the lower end face of the rotating part 201; the drive worm 3022 is connected to the power output end of the drive part 301 and rotates together; the drive worm 3022 meshes with the drive turbine 3021, driving the drive turbine 3021 to rotate, thereby driving the rotating part 201 to rotate.

[0070] In practice, the drive unit 301 is arranged horizontally, which can reduce the overall height of the device and facilitate its installation in situations where the space under the existing batching silo 5 is limited. It does not require changing the installation height of the original batching silo 5, which is beneficial for the modification of the original equipment.

[0071] In some implementations, such as Figure 9 As shown, the monitoring unit includes several distance sensors 4, which can be set from 5 to 20. The specific number can be set according to the specific situation and is not limited. The present invention preferably uses 8 sensors.

[0072] Specifically, the distance sensor 4 can be a sensor of the type of laser, infrared, ultrasonic, or millimeter-wave radar. The present invention preferably uses a laser ranging sensor, which is a technology already in use.

[0073] Specifically, laser rangefinders offer the following advantages: high measurement accuracy, a wide measurement range from a few centimeters to hundreds of meters, fast response speed suitable for measuring the distance of high-speed moving objects, non-contact measurement, good directionality, small spot size, strong resistance to color / material influence, better adaptability to black, dark, and reflective objects, stable measurement of transparent objects (glass, plastic), digital output for easy automation control, good environmental adaptability, a certain degree of resistance to natural light interference, and high protection levels (IP65, IP67), making them suitable for workshops, outdoor environments, and dusty environments.

[0074] Specifically, such as Figure 9 As shown, the distance sensor 4 is evenly arranged along the circumference of the rotating unit 2. It can be set on the inner wall of the rotating part 201 or on the fixed part 202. It transmits detection signals in real time to the axis of the rotating unit 2 and receives signals reflected by the material discharged from the outlet of the batching bin 5.

[0075] In this embodiment, the distance sensor 4 is used to collect the distance data between the edge of the material discharged from the outlet of the batching bin 5 and the distance sensor 4 in real time, and transmit the distance data to the control unit.

[0076] Specifically, during feeding, the material is discharged from the outlet of the feeding hopper 5. Under normal circumstances, the material flow maintains a certain cross-sectional shape according to the shape of the outlet. For example, if the outlet is circular, the cross-section of the discharged material flow is also approximately circular. At this time, the signal (laser ray) emitted by the distance sensor 4 irradiates the outer edge of the material flow, and the collected distance data is the distance from the edge of the material flow to the distance sensor 4 (since the material flow is fluid, signal jumps may occur; this can be set in the control unit to take the maximum value collected per unit time). The set of distance data collected by all distance sensors 4 is the cross-sectional shape data of the material flow. When a blockage occurs, such as... Figure 10 As shown, the material initially adheres to the inner wall of the mixing hopper 5 and gradually diffuses towards the center. The blockage area follows a similar pattern; when material stops flowing down at the blockage location, the distance data measured by the distance sensor 4 at that location increases, meaning the material flow cross-section is no longer approximately circular but rather concave at the blockage location. The control unit can then determine if a blockage has occurred. The average distance data from all distance sensors 4 can be processed and compared with a preset threshold range, allowing for further judgment and action based on the comparison results. Alternatively, the distance data from each distance sensor 4 can be processed individually. When the distance data from a particular distance sensor 4 increases to a certain threshold, a blockage can be identified at that location. The control unit can then control the drive unit 301 to rotate the scraping unit 101 to that position for localized scraping, saving time and energy.

[0077] In practical implementation, this invention abandons the traditional technical means of material blockage monitoring and adopts a distance sensor 4 structure. By monitoring the changes in the edge shape of the material flow, it can more specifically, intuitively and accurately determine the blockage location and then carry out local blockage clearing operations. Alternatively, it can determine the blockage situation based on the average distance data collected by all distance sensors 4 and then carry out high-power or low-power blockage clearing operations.

[0078] Furthermore, if a monitoring technique similar to that using an infrared transmitter and receiver is employed, the signal needs to penetrate the discharge port cross-section (transmitter at one end, receiver at the other). This means that even if a partial blockage occurs in the signal path, material continues to flow down at other points along the path, without affecting the signal. Only when the entire path is blocked will the signal change. Therefore, this technique cannot detect partial blockages. This invention uses a distance sensor 4, whose transmitted signal does not need to penetrate the discharge port cross-section but only illuminates the outer edge of the material flow. Therefore, when a partial blockage occurs in the signal's ray path (the material flow edge indents inward), it can cause a real-time change in the signal path length (the collected distance data changes in real-time), thereby allowing for real-time assessment of the degree of blockage. This enables the monitoring of partial material unblocking, providing more specific and accurate reference data for unblocking operations.

[0079] Another aspect of the present invention provides a method for controlling blockage in a smelting batching silo 5, the method comprising: S1, Initialize the unblocking device. The monitoring unit collects cross-sectional shape data in real time and transmits the cross-sectional shape data to the control unit. The unblocking device is in standby mode.

[0080] The cross-sectional shape data is a collection of distance data collected by each distance sensor 4.

[0081] S2: The control unit processes the cross-sectional shape data in real time to obtain the average distance data, and compares the average distance data with a preset threshold to determine the material flow status. If the material flow status is determined to be "unobstructed," then proceed to S3. If the material flow status is determined to be "slow," then proceed to S4. If the material flow status is determined to be "blocked," then proceed to S5. If the scraping operation time exceeds the preset operation time, the control unit issues a warning signal.

[0082] Specifically, changes in distance data from a distance sensor 4 can also be used to determine if a local blockage has occurred. If so, the drive unit 301 can be controlled to rotate a scraping unit 101 to that position to perform local unblocking operations.

[0083] S3, the unblocking device maintains its current state, the monitoring unit continues monitoring, and the drive unit 3 is not activated. Return to S2.

[0084] S4, the control unit sends a low-power start command to the drive unit 3. The drive unit 3 operates at low power, meaning the scraping force is small, driving the scraping unit 1 to rotate along the inner wall of the mixing bin 5 to perform low-power scraping operations. Return to S2.

[0085] S5, the control unit sends a high-power start command to the drive unit 3. The drive unit 3 operates at high power, meaning it has a greater scraping force, driving the scraping unit 1 to rotate along the inner wall of the mixing hopper 5 to perform a high-power scraping operation. Return to S2.

[0086] The control unit processes cross-sectional shape data in real time to obtain the average distance data, and compares the average distance data with a preset threshold to obtain the material flow state, including: S21, The control unit presets a threshold. The threshold is a data range, and the specific value can be set according to the size of the specific ingredient bin 5. For example, if the discharge port radius of the ingredient bin 5 is 50cm, the threshold range can be set to 30cm~40cm.

[0087] S22, the control unit obtains the set of distance data collected by distance sensor 4.

[0088] S23, the control unit processes the distance data set using a mean algorithm to obtain the mean value of the distance data. The mean algorithm is as follows:

[0089] in: This represents the mean of the distance data. The number of distance sensors is 4. This is the distance from the distance sensor 4 to the center of the rotating unit 2. For the first Distance data collected by distance sensor 4.

[0090] Specifically, The actual value is the radius of the discharge port of batching hopper 5 when there is no blockage initially. As blockage occurs and intensifies, this value gradually decreases.

[0091] S24, the control unit will Compare with the threshold. When When the maximum value is greater than the threshold, the material flow status is "unobstructed"; when... The material flow state is "slow" when it is between the minimum value and the maximum value of the threshold; when... When the material flow is less than the minimum threshold value, the material flow status is "blocked".

[0092] Low-power / high-power scraping operations include: The control unit sends a low-power / high-power forward start command to the drive unit 301 of the drive unit 3. When the forward operation time exceeds the preset forward operation time, the control unit sends a stop operation command to the drive unit 301. The control unit then sends a low-power / high-power reverse start command to the drive unit 301. When the reverse operation time exceeds the preset reverse operation time, the control unit sends a stop operation command to the drive unit 301. The above steps are repeated until the control unit determines that the material flow status is "unobstructed," at which point the control unit sends a stop command to the drive unit 301.

[0093] All the aforementioned connection relationships use the term "set" or similar terms. If it is a relatively fixed connection method, it can be understood as a fixed connection, and can be fixed by specific methods such as welding, threaded connection, riveting connection, etc., which will not be explained one by one.
