Description

Technical Field

[0001] The utility model relates to the technical fields of analytical chemistry and automatic control, and particularly relates to an automatic fire assay batching device. Background Art

[0002] As an important means for precious metal analysis, the accuracy of the batching process in the fire assay method is directly related to the accuracy of the analysis results. However, in the traditional fire assay batching process, the monitoring of the material weight mainly relies on manual operation of an electronic platform scale for intermittent weighing, and this method has many deficiencies. First of all, manual weighing is inefficient, and it is difficult to achieve real-time and continuous monitoring of the material weight, which easily leads to weight deviation in the batching process. Secondly, manual operation is easily affected by subjective factors such as reading errors and operation mistakes, further increasing the uncertainty of batching.

[0003] With the development of automation technology, although there have been some patented technologies in the market aiming to improve the automation level of batching, such as CN218012574U and CN210021777U, these technologies are still insufficient in the real-time monitoring and precise control of the material weight. They may not comprehensively solve the real-time problem of material weight monitoring, or the stability and reliability of their monitoring systems need to be further optimized to better adapt to the complex and changeable fire assay batching environment. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems existing in the existing automatic fire assay batching equipment, such as poor adaptability of crucibles, inaccurate and untimely material sampling, and low intelligence level, and to propose an efficient, precise and intelligent automatic fire assay batching device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An automatic fire assay batching device includes a frame, a turntable, mounting positions, a material sampler, as well as a PLC controller and a panel. Specifically, the frame serves as the support structure of the entire device, and several material samplers are installed at its upper end, while a rotatable turntable is connected to its lower end through bearings. There are several mounting positions on the turntable for placing containers such as crucibles for melting and enriching materials.

[0007] Preferably, there are several mounting positions on the turntable for fixing the crucibles and ensuring their stability during rotation. There are protrusions on the outer circle of the upper end of the mounting positions, which not only enhance the fixing effect of the crucibles but also ensure that the material sampler can accurately align with the crucible mouth during sampling.

[0008] Preferably, a number of material samplers are installed at the upper end of the frame corresponding to the installation positions on the turntable. The design of the material sampler is ingenious. Its upper part is a square and partially inwardly inclined thin-walled structure, which is convenient for the smooth introduction of materials; the lower part is a vertically downward pipe structure to ensure that the materials can be directly and accurately added to the crucible.

[0009] Preferably, in order to achieve real-time monitoring of the weight of the material, weight-sensing bosses corresponding one by one to the installation positions of the turntable are provided on the chassis of the frame. High-precision weight sensors are installed on these bosses, which can obtain the weight information of the material in the crucible in real time and accurately, providing data support for subsequent batching adjustment.

[0010] Preferably, in order to further improve the accuracy and stability of the weight, the high-precision weight sensor in the present utility model also has an automatic calibration function, which can automatically calibrate at the startup of the device or at a user-specified time. During the automatic calibration process, the sensor will refer to a preset standard weight or use an internal calibration device to automatically adjust its measurement parameters to eliminate the small deviations caused by environmental factors (such as temperature fluctuations). In addition, in order to intuitively display the calibration status, a calibration status indicator light is integrated on the PLC panel of this device. When the sensor is performing automatic calibration, the corresponding indicator light on the PLC panel will turn on a red light to prompt the user that the current calibration process is in progress; when the automatic calibration is completed, the red light goes out and a green light comes on, clearly indicating that the weight sensor has been calibrated and is ready for accurate weight measurement work. This design ensures that the weight sensor can provide accurate and reliable weight data in any working state, thereby further improving the overall performance and batching accuracy of the fire assay automatic batching device.

[0011] Preferably, the device is also equipped with a PLC panel as the control center of the whole system, where the PLC is connected to the motor through the bottom end of the frame. Through the programming control of the PLC panel, precise control of components such as the material sampler, turntable rotation, and weight sensor can be achieved, ensuring the automation and accuracy of the entire batching process. Among them, the programming control of the PLC panel is prior art and will not be elaborated here.

[0012] Preferably, quick cut-off valves are innovatively installed on the material channels between the material samplers and the corresponding installation positions. These quick cut-off valves are all precisely controlled by the PLC panel and can quickly cut off the material flow when needed to achieve the function of quickly stopping the discharge. This design not only enhances the safety of the batching process but also improves the operation flexibility and response speed.

[0013] Preferably, a soft sponge heat insulation layer is ingeniously arranged on the inner wall of the installation position. This sponge heat insulation layer closely adheres to the side wall of the installation position, forming an effective shock absorption barrier. This design aims to significantly reduce the interference of vibrations during equipment operation on the high-precision weight sensor, thereby ensuring that the weight sensor can work in a more stable environment and measure more accurate weight data. This is undoubtedly an important performance improvement for processes such as fire assay that require high-precision weights.

[0014] Preferably, the present utility model also preferably introduces a PLC panel as the control center of the entire automatic batching system. Through the intelligent programming control of the PLC panel, precise coordination and scheduling of key components such as the material sampler, turntable rotation mechanism, and weight sensor can be achieved. This design not only realizes the full automation of the batching process but also greatly improves the accuracy and efficiency of operation. It should be noted that although the programming control technology of the PLC panel belongs to the category of existing technologies, its integrated application in the present utility model undoubtedly brings a qualitative leap to the entire system.

[0015] Preferably, on the material channel between the material sampler and the corresponding installation position, the present utility model innovatively adds quick cut-off valves. These quick cut-off valves are also precisely controlled by the PLC panel and can instantly cut off the material flow when receiving a stop signal, achieving fast and safe discharge control. This design not only greatly enhances the safety of the batching process, avoiding potential risks caused by material overflow or misoperation, but also significantly improves the flexibility and response speed of operation, making the entire batching process smoother and more efficient.

[0016] Preferably, a material monitoring device is provided in the middle of the material sampler. The device includes: a cavity provided in the middle of the material sampler, with a central boss arranged inside the cavity; a floating indicator plate located on the central boss inside the cavity, interacting with the central boss through the lever principle. As the amount of material inside the material sampler changes, the indicator plate can float up and down around the boss fulcrum. Specifically, when the material is sufficient, the buoyancy pushes the indicator plate to rise to a high position; when the material decreases to a certain level or below, the buoyancy is not sufficient to support the weight of the indicator plate, causing it to automatically drop to a low position; a warning plate located above the indicator plate outside the material sampler, which is aligned with the external area of the material sampler and is significantly divided into two areas: green and red. When the indicator plate is in the high position, it blocks the red area and only exposes the green area, indicating that the material is sufficient; when the indicator plate drops, the red area is revealed as an intuitive warning for the need to replenish the material, reminding the operator to replenish the material in a timely manner.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] High-efficiency automation: By introducing a quick cut-off valve and precisely controlling it with a PLC panel, the rapid start and stop of material sampling are achieved, significantly enhancing the automation level and response speed during the batching process. Combined with the optimized mechanical structure design, the operation cycle is greatly shortened, the batching efficiency is improved, and the labor intensity of operators is effectively reduced.

[0019] Precise batching: Integrating high-precision weight sensors to achieve real-time and precise monitoring of material weight. Combined with intelligent control algorithms, the batching process is ensured to be accurate and error-free, enhancing the reliability of analysis results.

[0020] Easy to operate: The user-friendly operation interface and intelligent control system make the operation simpler and faster. The design of the material monitoring device, especially the cooperation of the floating indicator board and the warning board, enables the intuitive display of the material stock status. Operators can clearly understand the material situation at a glance and replenish it in a timely manner. In addition, the information display and control functions on the PLC panel further simplify the operation process and enhance the operation convenience.

[0021] Stable and durable: Adopting high-quality materials and advanced manufacturing processes ensures the stability and durability of the device, reducing the maintenance cost during long-term operation. Description of the Drawings

[0028] In order to make the above - mentioned objects, features and advantages of the present utility model more obvious and understandable, the following describes in detail the specific embodiments of the present utility model with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0029] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation.

[0030] Referring to the attached Figure 1 - attached Figure 5 The present utility model relates to an automatic assay batching device, which shows the main components of the device. The device mainly consists of a PLC controller, a frame 1 and a series of supporting components. The frame 1 serves as a support structure, and a rotatable turntable 2 is connected to the center of its chassis 11 through a bearing. The rotation of the turntable 2 is driven by a motor at the bottom end of the frame 1, and the motor is electrically connected to the PLC controller and precisely controlled by the PLC controller. A number of mounting positions 3 are evenly distributed on the turntable 2, and a protrusion 4 is designed at the outer edge of the upper end of each mounting position 3 for fixing a crucible or other containers to ensure the stability of the containers during rotation. A sponge heat insulation layer 8 is closely attached to the inner wall of the mounting position 3 to reduce the influence of the external temperature on the materials in the containers.

[0031] On the chassis 11 of the frame 1, high - precision weight sensors 7 are installed corresponding to some of the mounting positions 3 on the turntable 2, and a sponge heat insulation layer 8 is also padded on each sensor to isolate heat interference. These sensors are electrically connected to the PLC controller, and they real - time monitor and transmit the weight information of the containers at each mounting position to the PLC controller and display it through the PLC panel 6.

[0032] At the upper end of the frame 1, corresponding to each mounting position 3, a number of material samplers 5 are provided. The material sampler 5 has a unique design. The upper part is a square and partially inward - inclined thin - wall structure, which is convenient for the introduction and storage of materials; the lower part is a vertically downward pipe for precisely delivering the materials into the containers at the mounting positions 3. A quick - cut - off valve is installed in the material channel between the material sampler 5 and the corresponding mounting position 3, and the valve is electrically connected to the PLC controller and controlled by the PLC controller to open and close.

[0033] In addition, a material monitoring device is also provided in the middle of the material sampler 5. The device includes a cavity inside the material sampler, a central boss, a floating indicator plate 9, and a warning plate 10 located outside. As the quantity of the material inside the material sampler 5 changes, the indicator plate 9 will float up and down around the fulcrum of the central boss, and visually display the material inventory status by aligning with the warning plate 10 located outside. The warning plate 10 is significantly divided into two areas, green and red, indicating the status of sufficient material and the need to replenish the material respectively.

[0034] When the present utility model is in use, first, the required batching scheme, including parameters such as material types, ratios, feeding sequences, etc., is set through the PLC panel 6. Subsequently, the sample to be tested and the required materials are respectively placed in the crucible and the material sampler 5. After starting the device, the PLC controller will control the motor to drive the turntable 2 to rotate according to the preset batching scheme, and bring the containers on each mounting position 3 one by one to the corresponding position below the material sampler 5.

[0035] When the container reaches the specified position, the PLC controller will control the quick cut-off valve to open, and the material in the material sampler 5 will be accurately added into the container through the pipeline. At the same time, the high-precision weight sensor 7 monitors the weight change of the material in the container in real time and transmits the data to the PLC controller. Once the preset weight value is reached, the PLC controller will immediately control the quick cut-off valve to close and stop feeding.

[0036] During the entire batching process, the material monitoring device will monitor the material inventory status in the material sampler 5 in real time. When the material is insufficient, the indicator plate 9 will drop to the low position, and the red area will be exposed on the warning plate 10, reminding the operator to replenish the material in time.

[0037] After completing the batching of all mounting positions 3, the turntable 2 stops rotating, and the operator can take out the crucible for subsequent fire assay analysis. The entire batching process realizes automatic control and high-precision monitoring, greatly improving the analysis efficiency and the reliability of the results.

[0038] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and should be covered within the protection scope of the present utility model.
