Description
Technical Field
[0001] This invention relates to the field of metal smelting and testing technology, and in particular to an ash dish workbench and its automated operation method. Background Technology
[0002] In the field of metal smelting and ore testing, the feeding of lead clasps into ash dishes is a key preliminary step in ore composition analysis. Currently, the mainstream operation method relies on manual operation of clamps to pick up the lead clasps and feed them into the ash dishes one by one. The testing workbench is only equipped with a simple support surface for placing the ash dishes, without a dedicated automatic feeding mechanism. The flue gas collection mainly adopts the overall ventilation system of the workshop for unified ventilation, without supporting point-specific dust collection structures. When conducting batch testing, the feeding process is completed by manually picking up and putting in materials.
[0003] Manual close-range handling of high-temperature lead buckles poses a significant risk of burns. The toxic lead fumes generated from the melting of the buckles can spread directly, posing a risk of occupational poisoning to operators with long-term inhalation. Furthermore, manual alignment is inaccurate, leading to buckles falling off and material loss. Additionally, the process requires single-pan, single-time feeding, resulting in low efficiency for batch testing. Summary of the Invention
[0004] To address the aforementioned problems, this invention provides an ash dish workbench and its automated operation method. The invention features a platform that automatically transfers ash dishes, enabling fully automated flow, improving batch testing efficiency, and reducing occupational health hazards from lead dust.
[0005] To solve the above problems, the technical solution adopted by the present invention is as follows:
[0006] A ash tray workbench and its automated operation method include a support device, the support device including a support base and a support platform that slides horizontally on the upper end of the support base, and a material dropping device located on the moving path of the support platform. The material dropping device includes a first material dropping platform with a first array of openings on its surface and a second material dropping platform with a second array of openings on its surface. The material dropping device also includes a drive device for controlling the relative movement of the second material dropping platform relative to the first material dropping platform. A negative pressure suction pipe is arranged in an array at the lower end of the second array of openings. The bottom of the negative pressure suction pipe extends downward and the horizontal projection of the bottom of the negative pressure suction pipe is located at the center of the corresponding second array of openings.
[0007] Preferably, the bottom of the first array opening has an annular negative pressure suction opening, and both the negative pressure suction opening and the negative pressure suction pipe are connected to a negative pressure suction device.
[0008] Preferably, a squeeze touch valve is provided between the driving device and the second unloading platform. The squeeze touch valve is connected in series in the suction pipe of the negative pressure suction device. During the driving process of the driving device, after the squeeze touch valve is opened, it pushes the second unloading platform to move horizontally. After the squeeze touch valve is opened, the negative pressure suction opening and the negative pressure suction pipe perform negative pressure suction.
[0009] Preferably, the lower end of the second material feeding platform is also provided with vertically downward strip-shaped air blowing strips, which blow out a ring-shaped protective air curtain vertically downward while performing negative pressure suction.
[0010] Preferably, the driving device includes a driving telescopic rod and a connecting end, the connecting end being fixed to the second unloading platform, and the extrusion touch valve being disposed between the connecting end and the second unloading platform.
[0011] Preferably, the support platform includes a first support plate and a second support plate, and a lifting device is provided between the first support plate and the second support plate.
[0012] Preferably, a touch sensor is also provided between the negative pressure suction pipe and the second unloading platform to detect the unloading status of the lead buckle.
[0013] Preferably, a temporary storage device is also provided on the outside of the supporting device. The temporary storage device includes a temporary storage base and a temporary storage platform, and the temporary storage platform and the supporting platform are arranged in a stepped manner.
[0014] An automated operation method for an ash tray workbench, using the aforementioned ash tray workbench, includes the following steps: S1, controlling the first and second material feeding platforms to be staggered, and placing the lead buckle in the opening of the first array, then placing the ash tray to be fed on the upper part of the support platform; S2, driving the support platform to move the ash tray to the corresponding position below the opening of the first array; S3, controlling the second material feeding platform to move relative to the first material feeding platform to realize the dropping of the lead buckle, and the negative pressure suction pipe continuously sucks up the generated flue gas.
[0015] The beneficial effects of this invention are as follows:
[0016] Compared with existing technologies, the double-layer staggered hole structure of this invention enables simultaneous automatic feeding of multiple sets of lead buckles, replacing manual clamping operations and isolating operators from high temperatures and toxic fumes; the negative pressure pipeline is aligned point-to-point with each feeding point, and the fume capture efficiency is high, with no fume overflow or diffusion, greatly improving the laboratory working environment; it can also prevent lead buckles from falling directly into molten metal when there is a large height difference, ensuring the stability of the molten metal, and the carrying platform automatically transfers ash dishes, with fully automated flow, improving the efficiency of batch testing and reducing occupational health hazards of lead dust.

Detailed Implementation
[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0025] See attached document Figure 1 -Appendix Figure 6 A ash dish workbench and its automated operation method are disclosed. The workbench includes a support device 100, which includes a support base 110 and a support platform 120 that slides horizontally on the upper end of the support base 110. The support platform 120 supports the ash dish.
[0026] To address the deficiencies in the prior art, the present invention further includes a feeding device 300 located on the moving path of the support platform 120. The feeding device 300 enables automatic feeding of multiple lead buckles. The feeding device 300 includes a first feeding platform 310 with a first array opening 311 on its surface and a second feeding platform 320 with a second array opening 321 on its surface. When the first feeding platform 310 and the second feeding platform 320 are staggered, the first array opening 311 and the second array opening 321 are also staggered. At this time, the second feeding platform 320 can support the lead buckles, and the first array opening 311 can accommodate the lead buckles.
[0027] The unloading device 300 also includes a drive device 400 for controlling the relative movement of the second unloading platform 320 relative to the first unloading platform 310. A limit block 312 is also fixed at the lower end of the first unloading platform 310. The movement trajectory of the second unloading platform 320 can be restricted by the limit block 312 to prevent the second unloading platform 320 from moving to the outside, and ultimately ensure the stability of the first array opening 311 and the second array opening 321 being misaligned and docked.
[0028] A negative pressure suction pipe 322 is arranged at the lower end of the second array opening 321. The negative pressure suction pipe 322 can suck up the toxic gas generated during the melting of the lead buckle. The bottom of the negative pressure suction pipe 322 extends downward and the horizontal projection of the bottom of the negative pressure suction pipe 322 is located at the center of the corresponding second array opening 321. The bent bottom of the negative pressure suction pipe 322 can provide a small buffer for the lead buckle, so as to prevent the lead buckle from falling directly into the molten metal when the height difference is large, thus ensuring the stability of the molten metal.
[0029] The negative pressure suction pipe 322 can be a bent shape as shown in the attached drawing, or a straight inclined shape. The inclined state can support the fallen lead buckle. The negative pressure suction pipe 322 can be a round pipe as shown in the attached drawing, or it can be a flat pipe shape.
[0030] This solution features a horizontally sliding support platform 120 for transferring ash trays. The unloading station adopts a double-layer staggered unloading platform structure. The drive device 400 drives the second unloading platform 320 to move relative to the first unloading platform 310. Automatic batch unloading of lead buckles is achieved through the overlap and staggering of the two array openings. A negative pressure suction pipe 322 is installed directly below each second array opening 321 with its opening aligned with the center of the opening, which can capture the toxic fumes generated by the melting and high-temperature decomposition of lead buckles.
[0031] In summary, the double-layer staggered hole structure of this invention enables simultaneous automatic feeding of multiple sets of lead buckles, replacing manual clamping operations and isolating operators from high temperatures and toxic fumes. The negative pressure suction pipe 322 is aligned point-to-point with each feeding point, and the fume capture efficiency is high, with no fume overflow or diffusion, significantly improving the laboratory working environment. It also prevents lead buckles from falling directly into molten metal when there is a large drop, ensuring the stability of the molten metal. The 120-inch automatic transfer platform automatically transfers ash dishes, enabling fully automated flow, improving the efficiency of batch testing and reducing occupational health hazards from lead dust.
[0032] Furthermore, an annular negative pressure suction opening is provided at the bottom of the first array opening 311, and both the negative pressure suction opening and the negative pressure suction pipe 322 are connected to a negative pressure suction device.
[0033] The negative pressure suction opening and negative pressure suction pipe 322 form a double-layer negative pressure capture system. The upper annular opening absorbs and diffuses the flue gas, while the lower pipe captures the concentrated flue gas at the moment of material feeding. The dual negative pressure works together to prevent flue gas from escaping. The two share a single negative pressure device, simplifying the gas path layout and eliminating the need for multiple fans for separate control, thus reducing equipment investment and maintenance energy consumption. The annular opening surrounds the lead buckle and can fill any gaps at the top, capturing trace amounts of lead dust that slowly evaporates in the early stages of material feeding, thus solving the problem of upper flue gas escape defects caused by single bottom pipe suction.
[0034] Furthermore, a squeeze-activated valve is installed between the drive device 400 and the second unloading platform 320. The squeeze-activated valve is connected in series in the suction pipe of the negative pressure suction device. After the squeeze-activated valve is opened, the suction pipe of the negative pressure suction device is opened, realizing normal suction of flue gas. During the drive process of the drive device 400, the squeeze-activated valve is controlled first. After the squeeze-activated valve is opened, the second unloading platform 320 is pushed to move horizontally. After the squeeze-activated valve is opened, the negative pressure suction opening and the negative pressure suction pipe 322 are synchronously negative pressure suctioned. At this time, the negative pressure suction pipe 322 can be prepared for negative pressure suction in advance.
[0035] An integrated extrusion touch valve is connected between the drive unit 400 and the second unloading platform 320, and the touch valve is connected in series in the main pipeline of the negative pressure suction equipment. During the process of the drive mechanism pushing the platform, the valve is first extruded to open, and then the platform is moved to unload the material. After the valve is opened, the upper and lower negative pressure structures start suction simultaneously. This realizes the timing logic control of starting the negative pressure first and then unloading the material. The negative pressure airflow field is established in advance before unloading the material, and the flue gas is immediately sucked away as soon as it is generated, preventing the rapid leakage of smoke and dust under the condition of no negative pressure for a short period of time. Relying on the mechanical extrusion to trigger the valve body, there is no need for electronic components such as photoelectric and pressure sensors that are easily contaminated and fail due to smoke and dust. It operates stably under conditions of high lead dust and high temperature, reducing the cost of frequent sensor maintenance and replacement. The integrated action linkage design eliminates the need for a separate timing control program, and the equipment debugging logic is simple.
[0036] It should be noted that the above-mentioned extrusion touch valve can be an existing horizontally moving touch valve with reset elasticity. The valve seat and valve core are arranged horizontally. The valve seat is fixed to the connecting end 410, and the valve core is fixed to the drive telescopic rod 420. During the extension and retraction of the drive telescopic rod 420, the valve core is first controlled to move to control the touch valve to open. After the valve core moves to the limit position, the valve core and valve seat move synchronously, which finally drives the second material dropping platform 320 above to move synchronously.
[0037] Furthermore, vertically downward strip-shaped air blowing strips are also provided around the lower end of the second material dropping platform 320, which blow out a ring-shaped protective air curtain vertically downward while drawing in negative pressure.
[0038] When the strip-shaped air blowing bar and the negative pressure suction are started simultaneously, the air blowing bar sprays air downward to form a ring-shaped closed protective air curtain; the ring-shaped vertical air curtain forms an airflow barrier around the material drop area, blocking the horizontal airflow in the workshop from blowing away the flue gas, and preventing the negative pressure airflow from being disturbed by the external airflow. This creates an airflow distribution state with negative pressure suction from the top center and downward protection around the perimeter, ensuring that all dust is captured by the negative pressure system. It is also suitable for the control structure of the automatic lead buckle dispensing system, eliminating the need for physical baffles and making it simple and convenient.
[0039] Specifically, the drive device 400 includes a drive telescopic rod 420 and a connecting end 410. The connecting end 410 is fixed to the second unloading platform 320, and the extrusion touch valve is disposed between the connecting end 410 and the second unloading platform 320. The drive device 400 consists of the drive telescopic rod 420 and the connecting end 410. The connecting end 410 and the second unloading platform 320 are rigidly fixed, and the extrusion touch valve is directly assembled at the connection point between the two.
[0040] The touch valve is installed at the power transmission interface. The thrust of the drive telescopic rod 420 can directly and stably squeeze the valve body, and the trigger action is sensitive with no stroke loss. The integrated assembly structure is compact, does not occupy the effective arrangement space of the unloading platform, and will not interfere with the array opening arrangement. The overall mechanical transmission structure has no exposed precision electrical parts, is resistant to high temperature and lead dust corrosion, and is suitable for long-term continuous testing operations.
[0041] Specifically, the support platform 120 includes a first support plate and a second support plate, with a lifting device installed between the first and second support plates. The support platform 120 consists of upper and lower support plates, with independent lifting devices between the two plates, allowing for individual adjustment of the height of the upper ash tray.
[0042] This invention can precisely control the vertical distance between the ash dish and the discharge opening by adjusting the lifting distance according to the different specifications and heights of the ash dish. After the distance is adapted, the impact force of the lead buckle falling can be controlled, preventing the lead buckle from bouncing off the ash dish. The lifting structure can make the ash dish close to the discharge opening for receiving, reducing the space for flue gas diffusion and further improving the negative pressure capture effect. The equipment is compatible with a variety of standard and non-standard sized test ash dishes, making it more versatile.
[0043] Furthermore, a touch sensor is installed between the negative pressure suction pipe 322 and the second unloading platform 320 to detect the unloading status of the lead buckles. The touch sensor, installed at the assembly point between the negative pressure suction pipe 322 and the second unloading platform 320, monitors in real time whether the unloading of the lead buckles is successfully completed, relying on the sensing signal.
[0044] The above method can collect material feeding status signals in real time. If abnormalities such as lead buckle jamming, failure to fall, or material shortage occur, the system will immediately alarm and suspend the operation of the station to avoid the distortion of test data due to empty plates or insufficient material. The sensing point is close to the feeding channel, and the response speed is fast. There is no need for manual inspection of each plate, realizing automatic self-inspection of the feeding process, ensuring the accuracy of test results, and reducing the workload of re-inspection and rework.
[0045] Furthermore, a temporary storage device 200 is also provided outside the support device 100. The temporary storage device 200 includes a temporary storage base 210 and a temporary storage platform 220, which is arranged in a stepped manner with the support platform 120. An independent temporary storage device 200 is provided outside the support device 100, and the temporary storage platform 220 is arranged in a stepped manner with the support platform 120.
[0046] The stepped zoning layout allows for the temporary storage of empty ash trays, ash trays awaiting feeding, and ash trays that have been fed. Operators can pre-place batches of ash trays to be processed, and the equipment automatically circulates and transfers them without stopping the machine to wait for feeding. The high and low stepped structure facilitates the handling of ash trays by robotic arms or manual labor without interfering with the operation path, thereby increasing the continuous operation time of the entire set of equipment and making it suitable for scenarios involving large-scale ore testing and simultaneous processing of multiple batches of ash trays.
[0047] The invention will be further described below with reference to specific automated operation methods.
[0048] An automated operation method for an ash tray workbench includes the following steps:
[0049] S1. Control the first material feeding platform 310 and the second material feeding platform 320 to be staggered, and place the lead buckle in the first array opening 311. Then place the ash dish to be fed on the upper end of the bearing platform 120. The lead buckle feeding process is carried out manually, and the lead buckle is placed according to the number and distribution position of the ash dish.
[0050] S2. Drive the bearing platform 120 to move the ash dish to the corresponding position below the first array opening 311. At this time, it is necessary to ensure that multiple ash dishes are opposite to the corresponding first array opening 311 and are located directly below, so as to ensure that the lead buckle can fall into the corresponding ash dish normally.
[0051] S3. Control the second unloading platform 320 to move relative to the first unloading platform 310 to realize the unloading of lead buckles, and the negative pressure suction pipe 322 continuously sucks up the generated flue gas.
[0052] This invention enables a standardized closed-loop operation process, with no one coming into close contact with high-temperature lead buckles and fumes throughout the entire process; multiple ash dishes are fed in batches simultaneously, significantly shortening the processing time for a single batch of tests; fumes are continuously collected throughout the process, eliminating lead dust pollution and personnel burn hazards from the process flow level; the operation process can be connected to the laboratory automation control system to achieve unattended continuous testing.
[0053] In summary, this invention comprehensively improves upon the pain points of manual lead dust feeding in ore testing, including significant fumes, low efficiency, uneven feeding, and lead dust pollution. It employs a multi-layered, coordinated structure, including double-layered staggered-hole automatic feeding, double-layered negative pressure collection, annular air curtain isolation, mechanical linkage timing control, layered adjustable load capacity, automatic material drop detection, and stepped ash pan temporary storage, achieving fully automated and dust-free lead dust feeding. This significantly improves the efficiency of batch ore testing, ensures stable and reliable test data through standardized feeding, and completely isolates operators from high-temperature and toxic lead fumes, significantly reducing occupational disease risks in the laboratory. The structure is resistant to fumes and high temperatures, and is less prone to failure, making it suitable for the long-term, high-frequency use requirements of mineral processing and metallurgical laboratories.
[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
