Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment, and in particular to a crucible cleaning device and a coal quality analysis system. Background Technology

[0002] In the coal quality analysis industry, unmanned testing systems are used to test the ash, volatile matter, sulfur content, and calorific value of coal. This requires calorific value crucibles, ash crucibles, volatile matter crucibles, and sulfur crucibles, each with different characteristics: for example, sulfur crucibles are long and narrow with rhomboid ends; volatile matter crucibles have the largest lid diameter and the smallest thickness; calorific value crucibles have small diameters, short edges, and relatively low heights; while water-ash crucibles and volatile matter crucibles have similar diameters, their heights differ. As crucial containers for holding samples, the cleanliness of the crucible directly affects the accuracy of the experimental results.

[0003] Currently, some crucible cleaning devices exist. The cleaning mechanism consists of a vertically placed air pipe facing the crucible to be cleaned. The airflow blows towards the crucible to sweep away sample residues, thereby cleaning the inner wall of the crucible. However, since the air pipe is fixed during the blowing process, it can only clean the area that the airflow can directly impact. Sample residues will remain on the cleaning dead corners that cannot be impacted by the airflow. Furthermore, it cannot clean crucibles of different shapes and sizes from all angles. As a result, when the crucible is used again for analysis, the residual sample residues still attached to the crucible are easily regarded as impurities, affecting the accuracy of the analysis.

[0004] Therefore, there is an urgent need for a crucible cleaning device that can address the problem of cleaning crucibles of different shapes, achieve comprehensive cleaning of crucibles of different shapes, and reduce sample residue on crucibles. Utility Model Content

It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0052] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0053] This embodiment provides a coal quality analysis system applicable to industries such as power, steel, and coal chemical engineering, for detecting parameters such as ash content, volatile matter, sulfur content, and calorific value in coal. In this embodiment, the coal quality analysis system includes a coal quality testing device and a crucible cleaning device. The crucible 1 is placed on the coal quality testing device for testing. After testing, the crucible 1 is moved to the crucible cleaning device for cleaning. Then, the cleaned crucible 1 is moved back to the coal quality testing device for the next test. This process is repeated. By continuously moving the crucible 1 between the coal quality testing device and the crucible cleaning device, performing a cyclical operation of cleaning and testing, continuous testing of multiple substances can be achieved, improving testing efficiency. This system is suitable for scenarios requiring the testing of a large number of substances.

[0054] Different crucibles have different characteristics: for example, sulfur crucibles are long and narrow with rhomboid ends; volatile matter crucibles have the largest lid diameter and the smallest thickness; calorific value crucibles have small diameters, short edges, and relatively short heights; water ash crucibles and volatile matter crucibles have similar diameters but different heights.

[0055] To ensure that the crucible cleaning equipment can clean crucibles of different shapes, such as... Figures 1-2 As shown, in this embodiment, the crucible cleaning device includes a base, a support member 21, an inner wall cleaning mechanism 4, and an identification mechanism 7. The crucible 1 is mounted on the support member 21. The inner wall cleaning mechanism 4 is connected to the base and rotatably connected to the support member 21. The support member 21 can rotate relative to the base and can rotate from the loading position to the cleaning position. When the support member 21 switches to the cleaning position, the crucible 1 is positioned directly above the inner wall cleaning mechanism 4. The inner wall cleaning mechanism 4 includes a first spray member 41 and a spray mode adjustment component 42. The first spray member 41 is connected to the base and rotatably connected to the support member 21. The spray mode adjustment component 42 is connected to adjust the spray mode of the first spray component 41. The identification mechanism 7 is set in the inner wall cleaning mechanism 4. The identification mechanism 7 is used to identify the cleanliness of the crucible 1 and the shape of the inner wall of the crucible 1. The above settings enable the inner wall cleaning mechanism 4 to identify crucibles 1 of different shapes and perform personalized cleaning. This allows the cleaning dead corners of crucibles 1 of different shapes to be effectively cleaned by the spray mode adjustment component 42 driving the first spray component 41 to blow air along the designated trajectory to remove dust, thereby improving the cleaning effect of the crucible cleaning equipment.

[0056] Optionally, such as Figures 1-2As shown, in this embodiment, the first spray element 41 is a first air nozzle, which is conical in shape. The first spray element 41 includes a plurality of radially arranged air holes 411, which face the crucible 1 when it is in the clean position. The radially distributed air holes 411 allow the airflow to diffuse evenly from the center to the surrounding area. The multiple radially distributed air holes 411 can release airflow simultaneously from different directions. In this way, when the crucible 1 is in the clean position, the airflow can cover more areas of the crucible 1, effectively reducing the occurrence of blind spots in the airflow and ensuring that sample residues can be thoroughly blown away. The radially symmetrical layout makes the pressure distribution of the airflow very uniform, greatly reducing the possibility of airflow turbulence. During the blowing process, the residue will not be blown everywhere due to excessive local airflow, nor will the residue remain due to insufficient local airflow, thus ensuring the stability of the blowing process. In other embodiments, the first spray element 41 can also be a spray pipe or nozzle, as long as it can achieve the cleaning of the inner wall of the crucible 1.

[0057] Optionally, the aperture of the vent 411 can be 0.3 mm to 1 mm, and the axis of the vent 411 can be at an angle of 5 degrees to 25 degrees to achieve air jetting onto the crucible 1. In this embodiment, the aperture of the vent 411 can be 0.6 mm, and the axes of every two adjacent sets of vents 411 are at an angle of 15 degrees. The relatively small aperture of 0.6 mm allows the ejected gas to form a more concentrated airflow, accurately acting on the residue on the crucible 1, improving the cleaning effect, and avoiding insufficient force or excessive range of action due to gas dispersion, which could affect areas that do not need cleaning. Under a certain gas source pressure, this aperture allows the gas to obtain a suitable flow rate and pressure. The smaller aperture will increase the gas flow rate, and the increased flow rate will lead to a greater impact force of the gas on the residue, which is beneficial for more effectively removing stubborn residue. The axes of adjacent vents 411 are at an angle, which allows the airflow ejected from different vents 411 to act on the surface of crucible 1 at different angles, forming a more complex and comprehensive airflow coverage. This can avoid cleaning blind spots and ensure that residues on all parts of crucible 1 are affected by the airflow, thus being removed more thoroughly. The angled design allows the airflows to cooperate with each other, forming a turbulent effect, which makes the gas flow more fully in crucible 1.

[0058] Specifically, such as Figures 1-3As shown, in this embodiment, the inner wall cleaning mechanism 4 further includes a pusher 43. The fixed end of the pusher 43 is connected to the base, and the output end of the pusher 43 is connected to the spray mode adjustment component 42. The pusher 43 is used to push the first sprayer 41 to the inner wall cleaning working position. The pusher 43 can accurately push the first sprayer 41 to the inner wall cleaning working position, ensuring that the first sprayer 41 maintains a suitable distance from the inner wall of the crucible 1, thereby achieving efficient and precise cleaning. Different crucibles 1 may have different depths and inner diameters. The pusher 43 can flexibly adjust the insertion position of the first sprayer 41 according to the specific size of the crucible 1, so that the cleaning mechanism can adapt to crucibles 1 of various specifications, improving the versatility and flexibility of the equipment.

[0059] Optionally, such as Figures 1-3 As shown, in this embodiment, the propulsion component 43 is an electric push rod, and the spray mode adjustment component 42 is installed at the output end of the electric push rod. The electric push rod can precisely control the extension and retraction length and position of the push rod, thereby accurately pushing the first spray component 41 to the inner wall cleaning working position. Furthermore, it can precisely adjust the distance between the air nozzle and the inner wall of the crucible 1 according to different crucible 1 sizes and cleaning requirements, ensuring the consistency and stability of the cleaning effect. The electric push rod can provide sufficient thrust to ensure that the first spray component 41 can overcome various resistances and ensure that the air nozzle is stably pushed to the appropriate working position. In other embodiments, the propulsion component 43 can also be a cylinder or hydraulic cylinder, as long as it can accurately push the first spray component 41 to the designated position.

[0060] Specifically, such as Figures 1-3 As shown, in this embodiment, the spray mode adjustment component 42 includes a direction adjustment component 421, which includes a rotating part 4212 and a fixed part 4211. The rotating part 4212 is connected to the first spray component 41, and the fixed part 4211 is rotatably connected to the rotating part 4212. The rotating part 4212 is connected to the first spray component 41, and the fixed part 4211 is rotatably connected to the rotating part 4212. The fixed part 4211 is connected to the output end of the pusher 43. This allows the first spray component 41 to rotate relative to the fixed part 4211, thereby flexibly adjusting the orientation of the air nozzle according to actual needs to adapt to cleaning crucibles 1 of different shapes.

[0061] Optionally, such as Figures 1-3As shown, in this embodiment, the direction adjustment component 421 is a ball joint support, which includes a ball head (i.e., a rotating part 4212) and a ball socket (i.e., a fixing part 4211). The ball head is connected to the first spray component 41, and the ball head is disposed in the ball socket. The ball head and the ball socket are rotatably connected, allowing the first spray component 41 to precisely adjust its direction when cleaning the sample residue in the crucible 1, so that the air nozzle can be aimed at the residue in different positions in the crucible 1, ensuring that the cleaning work is comprehensive and without dead angles. By rotating the ball head in the ball socket, the first spray component 41 can flexibly switch between various angles to adapt to different shapes of the crucible 1 and the distribution of residues. Since the ball joint support can achieve multi-directional rotation, the first spray component 41 can reach all corners inside the crucible 1, effectively avoiding cleaning dead angles caused by the fixed direction of the air nozzle. This is important for maintaining the cleanliness of the crucible 1 and ensuring the accuracy of subsequent experiments. The ball joint support allows the first spray element 41 to rotate flexibly to adapt to the structure of crucibles 1 of different shapes. Regardless of the shape of the crucible 1, the air nozzle can be adjusted to a suitable cleaning trajectory for cleaning, improving the versatility of the equipment and reducing costs. In other embodiments, the ball joint support can also be replaced with a universal joint or a spherical bearing, as long as the blowing direction of the first spray element 41 can be adjusted.

[0062] Specifically, such as Figures 1-3 As shown, in this embodiment, the spray mode adjustment component 42 further includes a rotation drive component 422. The rotation drive component 422 includes a rotation drive part 4221 and a rotation linkage part 4222. The rotation drive part 4221 is disposed on the side of the first spray component 41. The rotation linkage part 4222 is connected to the rotation drive part 4221 and is also connected to the ball head. The rotation drive part 4221 is used to drive the rotation linkage part 4222 to rotate, thereby causing the ball head to rotate relative to the ball socket, realizing automated adjustment of the blowing direction of the first spray component 41. The rotation drive unit 4221 in the drive unit 422 can precisely control the rotation angle and speed, thereby accurately adjusting the blowing direction of the first spray element 41. It can accurately target the sample residue inside the crucible 1 that needs to be cleaned, improving the cleaning effect and accuracy, and avoiding the errors and inaccuracies that may occur during manual adjustment. The rotation drive unit 422 allows the first spray element 41 to flexibly adjust its direction. No matter how the shape of the crucible 1 changes, it can accurately guide the airflow to all corners inside the crucible 1, effectively cleaning the residue and improving the versatility of the cleaning equipment for crucibles 1 of different shapes.

[0063] Preferably, such as Figures 1-3As shown, in this embodiment, the rotation drive unit 4221 includes a linear motor, which is circumferentially arranged along the direction adjustment member 421. The rotation linkage unit 4222 includes a ball joint connector, the extension direction of the output end of the linear motor is the same as the extension direction of the ball joint connector, so that the ball joint can swing within the ball socket, thereby realizing the reciprocating swinging and blowing of the first spray member 41. The rotation drive unit 4221 also includes a stepper motor, which is disposed between the first spray member 41 and the ball joint. The fixed end of the stepper motor is connected to the ball joint. The rotation linkage unit 4222 also includes a gear transmission group, which includes a first gear and a second gear that cooperate and drive each other. The output end of the stepper motor is fixedly connected to the first gear, and the first spray member 41 is fixedly connected to the second gear. The rotation of the stepper motor drives the first gear to rotate, and the first gear and the second gear cooperate to make the second gear rotate around the first gear, thereby realizing the rotational spraying of the first spray member 41. In other embodiments, the rotation drive 422 can be a servo motor or a rotary cylinder, and the rotation linkage can be a lead screw or a timing belt, as long as it can realize the rotation and swing of the first spraying component 41 relative to the base, which will not be described in detail.

[0064] Preferably, in this embodiment, the inner wall cleaning mechanism 4 further includes an air pump and a gas flow regulating valve connected to the first spray element 41. The gas flow regulating valve is used to regulate the flow rate and intensity of the purging gas. The air pump can continuously and stably provide purging gas to the first spray element 41, ensuring the continuity of gas supply during the cleaning process. The gas flow regulating valve can accurately control the gas flow rate to avoid damage caused by excessive airflow, while ensuring sufficient gas flow to complete the cleaning task. By adjusting the gas flow rate, the intensity of the purging gas can be flexibly adjusted. When encountering stubborn sample residues, the gas flow rate can be appropriately increased to improve the purging intensity and better remove the residues; while for some relatively fragile crucibles 1 or situations where the cleaning intensity requirement is not high, the gas flow rate can be reduced to reduce the impact on the inner wall of the crucible 1 and extend the service life of the crucible 1.

[0065] Specifically, such as Figure 1 and Figure 4As shown, in this embodiment, the crucible cleaning equipment further includes a flipping mechanism 2. The flipping mechanism 2 includes a carrier 21, a crucible support 22, a rotating shaft 23, and a flipping drive 24. The crucible support 22 is disposed on the carrier 21, and the crucible 1 is placed on the crucible support 22. The rotating shaft 23 passes through both the carrier 21 and the inner wall cleaning mechanism 4, allowing the carrier 21 to rotate relative to the inner wall cleaning mechanism 4. The fixing part of the flipping drive 24 is disposed on the inner wall cleaning mechanism 4, and the output part of the flipping drive 24 is disposed on the carrier 21. The flipping drive 24 is used to drive the carrier 21 to rotate. By driving the carrier 21 to rotate around the rotating shaft 23, the carrier 21, i.e., the crucible 1, can be precisely rotated from the loading position to the cleaning position, or adjusted to other specific angle positions as needed. Precise flipping control and rapid position adjustment enable the relevant process operations to be performed more efficiently, reducing the time and labor intensity of manual operation, and also reducing the occurrence of collisions between the crucible 1 and the inner wall cleaning mechanism 4 due to inaccurate manual operation.

[0066] Optionally, in this embodiment, the tilting drive 24 includes a rotary motor and a transmission device. The rotary motor and the transmission device work together to drive the carrier 21 to tilt relative to the base from 0 degrees to 180 degrees. The rotary motor can precisely control its rotation angle, and then precisely drive the carrier 21 to rotate through the transmission device. The transmission device can effectively transmit the power of the rotary motor to the carrier 21, and can amplify or adjust the torque as needed to ensure that the resistance during the tilting process can be overcome. The tilting drive 24 ensures that the rotary motor and the transmission device maintain good performance during long-term operation, reduces equipment downtime caused by drive component failure, and improves the working efficiency and stability of the entire system. In other embodiments, the tilting drive 24 can also be a rotary hydraulic cylinder or a rotary pneumatic cylinder, as long as it can drive the carrier 21 to rotate relative to the inner wall cleaning mechanism 4.

[0067] Optionally, in this embodiment, the transmission device includes a reducer, a gear pair, a rotating shaft, bearings, and a carrier. The output shaft of the rotary motor is connected to the reducer, and a drive gear is mounted on the output shaft of the reducer. The carrier 21 is fixed on the rotating shaft, which is mounted on the inner wall cleaning mechanism 4 via bearings. A driven gear meshing with the drive gear is mounted on the rotating shaft. When the rotary motor starts, the speed is reduced and the torque is increased by the reducer, driving the drive gear to rotate. The drive gear meshes with the driven gear, causing the rotating shaft to drive the carrier 21 to rotate around the axis of the rotating shaft, achieving a 0-180 degree flip. The reciprocating flip of the carrier 21 between 0 and 180 degrees is achieved by controlling the forward and reverse rotation of the motor, and the flip angle is precisely controlled by a position sensor. In other embodiments, the transmission device can also be a chain drive or a belt drive, as long as it can achieve the flipping of the carrier 21 relative to the base.

[0068] Specifically, such as Figure 1 and Figure 5 As shown, in this embodiment, the crucible cleaning equipment further includes a clamping mechanism 3, which is disposed on the flipping mechanism 2. The clamping mechanism 3 is used to clamp the crucible 1 and can flip with the flipping mechanism 2. The clamping mechanism 3 includes a jaw assembly 31 and an opening and closing drive member 32. The jaw assembly 31 includes at least two jaws arranged opposite each other. Each jaw is connected to the opening and closing drive member 32. The opening and closing drive member 32 drives the two adjacent jaws to close or open, thereby achieving the clamping of the crucible 1.

[0069] Preferably, in this embodiment, the clamping mechanism 3 further includes a pressure sensor 33. The pressure sensor 33 is disposed between two adjacent grippers and provides real-time feedback on the clamping force. When the pressure sensor 33 is disposed between two grippers that are moving closer together, the gripping mechanism stops moving closer when the pressure sensor reading is too high, thereby avoiding damage. In other embodiments, the pressure sensor 33 can also be disposed at the clamping end of the gripper to detect the pressure at the clamping end. If the pressure is too high, the opening and closing drive 32 stops operating to avoid damage.

[0070] Preferably, such as Figure 1 and Figure 5 As shown, in this embodiment, the gripper assembly 31 includes two symmetrical grippers. The inner sides of the two symmetrical grippers are provided with stepped V-shaped grooves, the surfaces of which are covered with a polyurethane or silicone anti-slip layer. The stepped V-shaped groove design can conform to the surfaces of objects of various shapes. By adapting to different steps, a large contact area between the object and the gripper can be ensured when gripping objects of different diameters, thereby improving the stability and reliability of the gripping. Polyurethane and silicone are relatively soft, and can buffer the pressure of the gripper on the object to a certain extent when gripping it, preventing the gripper from scratching or damaging the crucible 1. When the gripper holds an object, due to the high coefficient of friction of polyurethane or silicone, the anti-slip layer is in close contact with the object surface, effectively increasing the friction and preventing the object from sliding during gripping. Even when gripping objects with smooth surfaces, the gripping firmness is ensured. In other embodiments, the grippers can be any other form, the grooves can be any other shape, and the anti-slip layer can be omitted, as long as the crucibles 1 of different shapes can be stably clamped. Further details will not be provided.

[0071] Preferably, in this embodiment, the crucible cleaning equipment further includes a vibration component, which is disposed on the clamping mechanism 3. The vibration component can drive the clamping component to vibrate, and the vibration of the clamping component can also cause the crucible 1 to vibrate. When the crucible 1 is in the cleaning position, the vibration component can be activated to drive the crucible 1 to vibrate, thereby shaking off the residue from the crucible 1.

[0072] Since the clamping mechanism 3 is set on the flipping mechanism 2, the flipping mechanism 2 flips and then drives the clamping mechanism 3 to flip. The clamping mechanism 3 can also clamp the crucible 1, so that the crucible 1 is flipped by the flipping mechanism 2 to achieve a more stable flipping from the loading position to the cleaning position, so that the residue in the crucible 1 can be poured out.

[0073] Specifically, such as Figure 1 As shown, in this embodiment, the crucible cleaning equipment further includes an outer wall cleaning mechanism 5, which is mounted on the flipping mechanism 2. The outer wall cleaning mechanism 5 includes a first connecting rod and a plurality of second air nozzles 52 arranged in a ring. An air source is connected to the second air nozzles 52. The first connecting rod is connected to the flipping mechanism 2, and all the second air nozzles 52 are connected to the first connecting rod. The second air nozzles 52 are positioned towards the crucible 1 and are used to blow clean the outer wall of the crucible 1. The multiple second air nozzles 52 are arranged in a ring and are all connected to the first connecting rod, allowing the outer wall of the crucible 1 to be blown clean from different angles by multiple air nozzles, ensuring uniformity of cleaning and avoiding cleaning dead zones. By blowing away impurities from the outer wall of the crucible 1, corrosion or damage to the crucible 1 can be avoided, extending the service life of the crucible 1 and reducing production costs. Simultaneous blowing by multiple air nozzles, compared to a single air nozzle, can complete the cleaning of the outer wall of the crucible 1 in a shorter time, saving cleaning time and improving overall production efficiency.

[0074] Optionally, in this embodiment, the first connecting member 51 is rotatably connected to the flipping mechanism 2, allowing adjustment of the angle of the second air nozzle 52 as needed. This enables cleaning of different parts and angles of the crucible 1, especially when the crucible 1 has an irregular shape or special cleaning requirements. It provides more comprehensive coverage of the outer wall of the crucible 1, ensuring no cleaning dead spots. By flexibly adjusting the angle and position of the cleaning mechanism, the airflow can be more precisely directed to the areas of the outer wall of the crucible 1 that need cleaning, avoiding wasted airflow in irrelevant areas and thus improving the cleaning effect. Adjustments can be made according to different states of the crucible 1, enhancing the adaptability and flexibility of the outer wall cleaning mechanism 5, enabling it to clean crucibles 1 of various shapes. In other embodiments, the first connecting member 51 and the flipping mechanism 2 can be connected in other ways, as long as cleaning of the outer wall of the crucible 1 is achieved; further details are omitted.

[0075] Optionally, such as Figure 1As shown, in this embodiment, the crucible cleaning equipment further includes a dust removal mechanism 6, which is installed on the inner wall cleaning mechanism 4. The dust removal mechanism 6 is used to remove dust from the crucible 1. The dust removal mechanism 6 includes a dust suction hood 61, a dust suction pipe 62, and a dust suction component 63. The dust suction hood 61 is fitted around the outer periphery of the first spray component 41 and is used to collect the residue blown off by the first spray component 41. The dust suction component 63 is connected to the dust suction hood 61 through the dust suction pipe 62 and is used to remove the dust from the inner wall cleaning mechanism 4 and the crucible 1. The dust collection hood 61, which is fitted around the outer periphery of the first spray component 41, precisely collects the residue blown off by the first spray component 41, preventing the residue from spreading in the air or falling into the surrounding environment. This improves the efficiency and effectiveness of residue collection. The dust collection component 63 is connected to the dust collection hood 61 via the dust collection pipe 62, which can promptly absorb the residue diffused in the inner wall cleaning mechanism 4 and the residue that falls into the dust collection hood 61, helping to maintain the cleanliness of the work area and reducing the frequency and workload of manual cleaning. In other embodiments, the dust collection mechanism 6 can be any other structure, as long as it can collect the blown-off residue, which will not be described in detail here.

[0076] Optionally, the identification mechanism 7 is disposed in at least one of the plurality of vents 411, and the identification mechanism 7 faces the crucible 1 when it is in the clean position. The identification mechanism 7 is electrically connected to the inner wall cleaning structure. The identification mechanism 7 can identify the shape and cleanliness of the crucible 1. The identification mechanism 7 can also be linked with the inner wall cleaning mechanism 4. According to preset rules and standards, it can automatically make corresponding decisions for different identification results without human intervention, thereby improving the level of intelligence in the production process. Different treatment methods are adopted for crucibles 1 with different shapes and cleanliness levels, avoiding over-treatment or under-treatment, thereby optimizing resource utilization and reducing costs.

[0077] Optionally, such as Figures 1-2As shown, in this embodiment, the identification mechanism 7 is embedded in one of the multiple air holes 411 located at the center of the first spray element 41. The central position of the identification mechanism 7 in the first spray element 41 provides a natural advantage for identifying the overall shape of the crucible 1. It ensures that the identification mechanism 7 uses the central axis of the crucible 1 as a reference for detection, more accurately acquiring the shape information of the crucible 1, reducing shape misjudgments caused by eccentricity, and improving identification accuracy. It also allows for radial observation from the center outwards, scanning and identifying the interior of the crucible 1 without blind spots, facilitating the complete detection of all parts of the crucible 1, including edges and corners. This is particularly beneficial for detecting subtle shape changes or cleaning issues. The embedded installation isolates the identification mechanism 7 from the surrounding environment, preventing direct collisions with the crucible 1, thus effectively protecting both the identification mechanism 7 and the crucible 1, extending their service life, and reducing the probability of malfunctions due to environmental factors. In other embodiments, the identification mechanism 7 can be placed within multiple air holes 411, as long as it can achieve the identification of the crucible 1.

[0078] Optionally, in this embodiment, the identification mechanism 7 includes a high-definition camera. The high-definition camera can capture detailed images of the crucible 1. By analyzing the images, the shape of the crucible 1 can be accurately identified. The high-definition camera can also capture minute details on the surface of the crucible 1, clearly showing the cleanliness of the inner and outer walls, thereby accurately assessing its cleanliness level. The high-definition camera provides high-resolution images, ensuring the accuracy and reliability of the detection results. It can detect very small shape changes and cleanliness issues, helping to promptly identify potential safety hazards and quality problems. As part of the identification mechanism 7, the high-definition camera can be easily integrated with other devices and systems to achieve automated identification, analysis, and decision-making processes, reducing manual intervention, improving the automation and intelligence level of the production process, and reducing labor costs and human error. In other embodiments, the high-definition camera can be replaced with a 3D laser scanner, etc., as long as it can identify the shape and cleanliness level of the crucible 1.

[0079] Specifically, in this embodiment, the crucible cleaning equipment also includes a control mechanism. The control mechanism is electrically connected to the identification mechanism 7, the inner wall cleaning mechanism 4, the outer wall cleaning mechanism 5, the flipping mechanism 2, the clamping mechanism 3, and the dust removal mechanism 6, so that the identification mechanism 7, the inner wall cleaning mechanism 4, the outer wall cleaning mechanism 5, the flipping mechanism 2, the clamping mechanism 3, and the dust removal mechanism 6 work together in a predetermined order and logic to achieve automated cleaning of crucibles 1 of various shapes, reduce manual intervention, and accurately control the action parameters of each mechanism to improve cleaning efficiency.

[0080] It should be noted that the control mechanism is an existing structure, and setting up a control mechanism in crucible cleaning equipment is a conventional practice in this field. In this embodiment, any communication harness in the prior art can be used to connect with the identification mechanism 7, the inner wall cleaning mechanism 4, the outer wall cleaning mechanism 5, the flipping mechanism 2, the clamping mechanism 3, and the dust removal mechanism 6, etc., using any connection method in the prior art. As long as the automated cleaning of crucibles 1 of various shapes can be achieved, no further details will be provided.

[0081] Preferably, in this embodiment, the identification mechanism 7 can identify the shape of the crucible 1. When the crucible 1 is identified as circular or square, the identification mechanism 7 transmits an electrical signal to the control mechanism, which then transmits the electrical signal to the rotation drive 422. The rotation drive drives the first spray member 41 to rotate and blow towards the inner wall of the crucible 1 along the circumferential direction of the inner wall. When the crucible 1 is identified as rectangular, elliptical, or a rectangular irregular shape, the identification mechanism 7 transmits an electrical signal to the control mechanism, which then transmits the electrical signal to the rotation drive 422. The rotation drive drives the first spray member 41 to reciprocate and blow towards the inner wall of the crucible 1 along its extension direction. The identification mechanism 7 can also identify and compare the original crucible 1, the crucible 1 after testing, and the cleaned crucible 1, identify the area of ​​residue, and detect the degree of cleaning. If the clarity meets the standard, it sends an electrical signal to the control mechanism, which then sends an electrical signal to drive the flipping mechanism 2 to flip the crucible 1 from the cleaned position to the loading position. If the clarity does not meet the standard, it sends an electrical signal to the control mechanism, which then sends an electrical signal to the identification mechanism 7 to identify the shape of the crucible 1 and perform targeted secondary cleaning based on the shape of the crucible 1 until the cleaning degree meets the standard. This allows the crucible cleaning equipment to clean round or square crucibles and... The system can clean crucibles 1 of various shapes, such as rectangular, oval, or rectangular irregular shapes, enhancing its versatility and applicability. It can meet the cleaning needs of different types of crucibles 1. The automated cleaning process automatically adjusts the cleaning method according to different shapes, eliminating the need for manual operation and greatly improving the efficiency of cleaning crucibles 1, saving time and labor costs. By identifying the area of ​​residue, the system can detect the degree of cleaning and perform secondary cleaning until the standard is met, ensuring the cleaning quality of crucibles 1 and providing a good foundation for subsequent operations, reducing the impact of residual residue on test results.

[0082] Preferably, such as Figure 1 As shown, in this embodiment, a first buffer 24 is provided below the side of the support member 21 away from the inner wall cleaning mechanism 4. After cleaning is completed, the flipping mechanism 2 will drive the crucible 1 to flip back to its original position. By setting the first buffer 24 at the bottom, the impact force when the flipping mechanism 2 falls back can be effectively buffered, thus effectively protecting the equipment. At the same time, the setting of the first buffer 24 can also reduce the mechanical impact when the clamping mechanism 3 clamps the crucible 1, and reduce the mechanical impact after flipping.

[0083] Optionally, such as Figure 1 As shown, in this embodiment, the first buffer 24 is a first spring. When the flipping mechanism 2 drives the crucible 1 to flip back to its original position, the first spring can effectively absorb the impact force generated when the flipping mechanism 2 falls back, converting the kinetic energy into the elastic potential energy of the spring, thereby reducing the impact on the equipment and protecting the various components of the equipment from damage. When placing the crucible 1, the spring can also buffer the clamping force of the clamping mechanism 3, reducing mechanical impact. In other embodiments, the first buffer 24 can also be a silicone block or a hydraulic buffer, as long as it can buffer the impact force generated when the flipping mechanism 2 falls back.

[0084] Preferably, such as Figure 1 As shown, in this embodiment, a second buffer spring is provided on the side of the inner wall cleaning mechanism 4 away from the flipping mechanism 2. After the flipping mechanism 2 flips, it presses against the second buffer spring. By providing the second buffer spring, the impact force when the flipping mechanism 2 flips can be effectively buffered, thus effectively protecting the equipment.

[0085] Optionally, such as Figure 1 As shown, in this embodiment, the second buffer 44 is a second spring. The second spring can deform when subjected to external force, absorb energy, and return to its original shape after the force disappears. This allows it to effectively cope with the impact force generated when the flipping mechanism 2 flips, buffering energy through elastic deformation. In other embodiments, the second buffer 44 can also be a rubber block or a polyurethane buffer, as long as it can buffer the impact force when the flipping mechanism 2 flips.

[0086] Specifically, in this embodiment, the crucible cleaning equipment also includes a transfer mechanism, which is used to transfer the cleaned crucible 1 to a designated location, or to transfer the uncleaned crucible 1 after use to the flipping mechanism 2. The automated transfer process greatly shortens the waiting time of the crucible 1 between different processes, speeds up the production pace, and thus improves the overall production efficiency.

[0090] S3: Activate the flipping mechanism 2 to flip the crucible 1 from the loading position to the cleaning position;

[0092] S5: The spray mode adjustment component 42 drives the first spray element 41 to rotate and blow towards the inner wall of the crucible 1 with the inner wall circumferential direction as the blowing trajectory.

[0093] S6: The spray mode adjustment component 42 drives the first spray element 41 to reciprocate and blow towards the inner wall of the crucible 1 along its extension direction.

[0094] S7: Activate the dust removal mechanism 6 to collect the dust blown down;

[0095] S8: Activate the identification mechanism 7 to identify the cleaning effect of crucible 1. If the specified cleaning standard is met, proceed to S9. If the specified cleaning standard is not met, return to S5 or S6. If the previous cleaning was performed by S5, return to S5. If the previous cleaning was performed by S6, return to S6.

[0096] S9: Start the flipping mechanism 2 to flip the crucible 1 from the cleaning position to the loading position.
