Description

Technical Field

[0001] This utility model relates to the field of metallurgy, and more specifically, to a fire-testing ash blowing furnace for reducing silver loss. Background Technology

[0002] The fire test ash blowing furnace is a commonly used experimental device for metal detection, especially for determining the content of gold, silver and precious metals.

[0003] Ash blowing involves placing the lead granules into an ash pan that has been preheated in a 900℃ high-temperature furnace for 20 minutes. The furnace door is then closed, and the temperature is maintained at 900℃ until the lead granules are completely melted. Ash blowing is then carried out at around 860℃, and the process takes about 1 hour. The end of ash blowing is indicated by two "flashes" in the granules.

[0004] In the current ash blowing furnace, the determination of the ash blowing endpoint is mainly done manually. This involves repeatedly opening the furnace door and visually observing the process, and then judging whether the ash blowing endpoint has been reached based on experience.

[0005] The disadvantages of the above method are: repeated manual opening of the furnace door leads to heat loss; harmful gases are generated during the ash blowing process, which can harm the operators; and it is impossible to continue observation when the furnace door is closed, which leads to missing the end of the ash blowing process and increasing silver loss.

[0006] Therefore, there is an urgent need for a fire-testing gold ash blowing furnace to solve the above problems. Utility Model Content

[0007] One objective of this invention is to provide a new technical solution for a fire-testing ash blowing furnace that reduces silver loss, thereby reducing manual operation, ensuring personnel health, and improving the accuracy of ash blowing endpoint testing.

[0024] Other features and advantages of the present invention will become clear from the following detailed description of exemplary embodiments of the present invention with reference to the accompanying drawings.

[0025] like Figures 1 to 4 As shown, a fire-testing ash blowing furnace for reducing silver loss in one embodiment of this application includes a furnace body 100, in which a furnace chamber 110 for placing ash pans is provided. The furnace body 100 is characterized by having an endoscope hole that communicates with the furnace chamber 110. An industrial camera 210 is mounted on the endoscope hole through a heat-insulating glass 220. The industrial camera 210 faces the furnace chamber 110. The industrial camera 210 is connected to a control system.

[0026] The ash pan is placed in the furnace chamber 110 for ash blowing test. The control system analyzes the images captured by the industrial camera 210 and can identify the flash phenomenon that occurs during the ash blowing process. This allows for automatic monitoring of different ash pans at the same time, reducing manual intervention, improving accuracy, reducing labor costs, and reducing the occurrence of safety accidents.

[0027] The control device, such as an industrial computer, is equipped with image recognition software and other corresponding programs. It can be trained to recognize the flashing phenomenon of different ash pans during the ash blowing process, record the number of flashes of the relevant ash pans, and issue alarms to notify relevant personnel.

[0028] In one embodiment of this application, the heat-insulating glass 220 is quartz glass. Multiple layers of quartz glass can be provided to form a vacuum insulation layer, thereby improving the heat insulation effect.

[0029] In one embodiment of this application, the control system includes a display screen and an alarm system. The display screen displays the image from the industrial camera 210, and the alarm system sounds an alarm when ash blowing is completed. The display screen can show the status of the ash pan in real time for easy observation by personnel. The alarm system is, for example, an audible and visual alarm.

[0030] In one embodiment of this application, a furnace door 120 is provided on the furnace body 100. The furnace door 120 is hinged to the furnace body 100 and connected to an opening and closing mechanism. The opening and closing mechanism is used to control the opening or closing of the furnace door 120 and the furnace chamber 110. Using an opening and closing mechanism eliminates the need for manual intervention, thus protecting personnel. Opening and closing mechanisms are provided on both sides of the furnace door 120.

[0031] In one embodiment of this application, the top of the furnace door 120 is hinged to the top of the furnace body 100. The opening and closing mechanism includes an opening and closing cylinder 310 and a connecting rod 320. One end of the connecting rod 320 is rotatably connected to the bottom of the furnace door 120, and the other end is rotatably connected to the side of the furnace body 100. The piston rod of the opening and closing cylinder 310 is rotatably connected to the middle of the connecting rod 320. The opening and closing cylinder 310 pushes the connecting rod 320, and when the connecting rod 320 moves, it drives the furnace door 120 to open or close. The opening and closing cylinder 310 is located on both sides of the furnace body 100, which can prevent the heat from burning the opening and closing cylinder 310 when the furnace door 120 is opened, thus avoiding a reduction in its lifespan.

[0032] In one embodiment of this application, a foot switch 330 is connected to the opening and closing cylinder 310. Using the foot switch 330 allows operation while holding the ash container, meaning the door can be closed by foot as soon as the ash container is removed, thus avoiding heat loss.

[0033] In one embodiment of this application, a protective cover 230 is fixed to the top of the furnace body 100, and the industrial camera 210 and the heat-insulating glass 220 are both installed in the protective cover 230. The protective cover 230 can protect the industrial camera 210, and water cooling, air cooling, or other devices can be added to the protective cover 230 to cool the industrial camera 210, thereby improving the service life of the industrial camera 210.

[0034] In operation, the device is operated manually by stepping on a foot switch, which opens the furnace door via a cylinder. The operator then places the ash trays in and begins the ash blowing process. An industrial camera observes the ash trays through a quartz glass screen, providing real-time monitoring until ash blowing is complete. When ash blowing is complete, a notification will appear on the computer screen, and the system will simultaneously alert the operator to open the door and remove the trays. This process continues until all trays are removed, ending the ash blowing operation.

[0035] According to one embodiment of this disclosure, the beneficial effect of using this fire test ash blowing furnace is that: the interior of the furnace can be directly observed with an industrial camera, providing a better field of view and avoiding the impact of blind spots on observation accuracy. Industrial cameras can observe the inside of the furnace in real time and accurately capture flashes through the control system, eliminating the need for frequent manual opening of the furnace for observation and making the detection more accurate. It enables automated observation and judgment, saving labor costs and reducing the probability of being harmed by toxic gases during manual operation.
