[0038] The fire assay analysis method is the main detection method for gold and silver analysis and trade arbitration in the domestic and foreign gold industries. According to the provisions of the national standard, the main technological steps of the fire assay detection method include main steps such as batching, mixing, melting, cupellation, parting, weighing, etc. The purpose of the fire assay parting process is to convert the gold-silver alloy grains after cupellation into gold grains, which is convenient for the inspector to determine the mass of gold in the sample. During the fire assay parting process, steps such as dissolving silver in nitric acid, washing, and drying the gold-silver alloy grains are required. After the gold-silver alloy grains are treated with nitric acid, the silver in the gold-silver alloy grains is dissolved by nitric acid and sponge gold with more pores is formed, which leads to the pores in the sponge gold affecting the drying efficiency of the sponge gold during the drying process of the sponge gold. Therefore, there is an urgent need for a new type of parting device to improve the drying efficiency of gold grains.

[0039] To solve the technical problem of how to provide a new type of parting device to improve the drying efficiency of gold grains, the present utility model provides a parting device provided with a water vapor extraction device 3. During the process of drying and carrying the gold grains in the heating device 1, the water vapor extraction device 3 extracts the water vapor in the carrying device 1, and at the same time promotes the flow of air in the carrying device 1, so as to achieve the technical effect of improving the drying efficiency of gold grains.

[0040] As Figure 1 shown Figure 1 is a schematic structural diagram of a gold separation device provided with a water vapor extraction device 3 according to the present utility model. The gold separation device includes: a carrying device 1, a heating device 2, and a water vapor extraction device 3. Among them, the carrying device 1 is used to carry gold particles; the upper end surface of the heating device 2 is provided with a receiving groove for receiving the carrying device 1, and is used to heat the carrying device 1 placed in the receiving groove; the water vapor extraction device 3 is arranged on the heating device 2. When the carrying device 1 is placed in the receiving groove, the extraction end of the water vapor extraction device 3 extends into the carrying device 1 to extract the water vapor in the carrying device 1. It can be understood that in this embodiment, when the gold separation device dries the gold particles in the carrying device 1, the carrying device 1 carrying the gold particles is placed in the receiving groove on the upper end surface of the heating device 2, and the water vapor extraction device 3 is controlled to extend the extraction end of the water vapor extraction device 3 into the carrying device 1, and the heating device 2 and the water vapor extraction device 3 are started. During the process of the heating device 2 heating the gold particles in the carrying device 1, the water vapor in the carrying device 1 is continuously extracted through the water vapor extraction device 3, thereby reducing the humidity in the carrying device 1 to achieve the technical effect of improving the drying efficiency of the gold particles; at the same time, during the process of the water vapor extraction device 3 continuously extracting the water vapor in the carrying device 1, the water vapor extraction device 3 will also accelerate the air flow in the carrying device 1, thereby further improving the drying efficiency of the gold particles.

[0041] Furthermore, as Figures 2 - 4 shown, in this embodiment, the water vapor extraction device 3 includes a first suction pipe 31, a support frame 32, and a sliding device 33. The support frame 32 is arranged in a direction perpendicular to the upper end surface of the heating device 2. The sliding device 33 is slidably arranged on the support frame 32. The first suction pipe 31 is fixedly arranged on the sliding device 33. One end of the first suction pipe 31 is the extraction end, and the extraction end is arranged towards the heating device 2. When the sliding device 33 moves along the support frame 32 towards the heating device 2, the extraction end extends into the carrying device 1. It can be understood that in this embodiment, the first suction pipe 31 in the water vapor extraction device 3 can slide up and down through the sliding device 33, that is, the first suction pipe 31 moves away from or close to the heating device 2. Then, by moving the first suction pipe 31, it is possible to prevent the first suction pipe 31 from causing movement interference to the carrying device 1 during the process of transferring the carrying device 1.

[0042] Furthermore, as Figure 3As shown, in this embodiment, the water vapor extraction device 3 further includes a first limiting mechanism 34. The first limiting mechanism 34 is arranged on the support frame 32, and the first limiting mechanism 34 is located on the movement track of the sliding device 33. The first limiting mechanism 34 is used to limit the sliding track of the sliding device 33. It can be understood that in this embodiment, the first suction pipe 31 has two states during use, that is, the first state when the first suction pipe 31 is close to the heating device 2 to extract the water vapor in the carrying device 1, and the second state when the first suction pipe 31 is far from the heating device 2 to prevent the first suction pipe 31 from interfering with the movement of the carrying device 1. In this embodiment, the first limiting mechanism 34 is arranged on the support frame 32. When the sliding device 33 controls the first suction pipe 31 to move to the first position or the second position, the first limiting mechanism 34 controls the sliding device 33 to stop sliding. Through the first limiting mechanism 34, not only can the moving position of the first suction pipe 31 be accurately controlled, but also the movement of the sliding device 33 is controlled by the first limiting mechanism 34, reducing the operation difficulty of the sliding device 33.

[0043] Exemplarily, in this embodiment, the first limiting mechanism 34 is a contact trigger device. The water vapor extraction device 3 further includes a first driving mechanism for driving the sliding device 33 to slide. The first driving mechanism is electrically connected to the first limiting mechanism 34. When the sliding device 33 contacts the first limiting mechanism 34, the first limiting mechanism 34 controls the first driving mechanism to stop. It can be understood that in this embodiment, the first limiting mechanism 34 can send a stop command to the first driving mechanism. When the sliding device 33 contacts the first limiting mechanism 34, the first limiting mechanism 34 is triggered by the sliding device 33 and sends a stop command to the first driving mechanism. The first driving mechanism receives and responds to the stop command, and then controls the sliding device 33 to stop.

[0044] Furthermore, in this embodiment, the first limiting mechanism 34 is slidably connected to the support arm. It can be understood that in this embodiment, the first limiting mechanism 34 can slide along the support arm. By adjusting the position of the first limiting mechanism 34 on the support arm, the movement track of the sliding device 33 is controlled, further reducing the operation difficulty of the sliding device 33.

[0045] Furthermore, in this embodiment, the gold separating device further includes a handling device 4 for moving the carrying device 1 to or from the receiving groove.

[0046] It can be understood that the detailed operation steps of the fire assay parting process include acetic acid treatment, button flattening, 1+7 nitric acid treatment, acid replacement, 1+2 nitric acid treatment, cleaning, drying, annealing, collecting gold grains, etc. Therefore, during the above process of the gold grains in the loading device 1, the handling device 4 drives the loading device 1 to transfer between the mechanisms for implementing the above steps, increasing the automation degree of the parting device.

[0047] Furthermore, as Figure 5 shown, in this embodiment, the handling device 4 includes a first motion slide rail 41, a second motion slide rail 42 and a manipulator assembly 43. The heating device 2 is arranged along the direction of the first motion slide rail 41; the second motion slide rail 42 is vertically arranged on the first motion slide rail 41 and is slidably connected to the first motion slide rail 41. The manipulator assembly 43 is slidably arranged on the second motion slide rail 42 and is used to handle the loading device 1. It can be understood that in this embodiment, the first motion slide rail 41 is defined as the X-axis direction, and the second motion slide rail 42 perpendicular to the first motion slide rail 41 is the Y-axis direction. During use, the first motion slide rail 41 and the second motion slide rail 42 are used to control the manipulator assembly 43 to move the handling device 4 in any direction of the X-Y axis.

[0048] Exemplarily, as Figure 5 shown, the manipulator assembly 43 includes a base 44, a driving device 45, a first fork clamp 46 and a second fork clamp 47. The base 44 is slidably arranged on the second motion slide rail 42. The driving device 45 is fixedly arranged on the base 44. The first fork clamp 46 and the second fork clamp 47 are respectively arranged on both sides of the driving device 45. The driving device 45 is used to drive the first fork clamp 46 or the second fork clamp 47 to move, and the moving directions of the first fork clamp 46 and the second fork clamp 47 are opposite. It can be understood that the base 44 is slidably arranged on the second motion slide rail 42, and through the second motion slide rail 42, the base 44 can slide up and down in the reverse direction of the Y-axis. The driving device 45 is fixedly arranged on the base 44. The first fork clamp 46 and the second fork clamp 47 are respectively arranged on both sides of the driving device 45, and the first fork clamp 46 and the second fork clamp 47 are arranged perpendicular to the two-dimensional plane formed by the X-Y axis. When the driving device 45 drives the first fork clamp 46 and the second fork clamp 47 to move, the first fork clamp 46 and the second fork clamp 47 move simultaneously in the X-axis direction, and the moving directions of the first fork clamp 46 and the second fork clamp 47 are opposite.

[0049] Further, in this embodiment, the handling device 4 further includes a second limiting mechanism 48 and a second driving mechanism. The second driving mechanism is used to drive the manipulator assembly 43 to move along the second movement slide rail 42. The second limiting mechanism 48 is arranged on the second movement slide rail 42, and the second limiting mechanism 48 is located on the movement track of the manipulator assembly 43. The second limiting mechanism 48 is electrically connected to the second driving mechanism. When the manipulator assembly 43 contacts the second limiting mechanism 48, the second limiting mechanism 48 controls the second driving mechanism to stop. It can be understood that during the process of the manipulator assembly 43 handling the loading device 1, there is a lateral movement along the direction of the first slide rail and a longitudinal movement along the second slide rail. Among them, compared with the lateral movement, the movement track of the longitudinal movement is relatively fixed. Therefore, in this embodiment, the second limiting mechanism 48 is arranged on the second movement slide rail 42, and the movement track of the manipulator assembly 43 is controlled by the second limiting mechanism 48, reducing the operation difficulty when the second driving mechanism drives the manipulator assembly 43.

[0050] Further, in this embodiment, the second limiting mechanism 48 is slidably connected to the second movement slide rail 42, and the second limiting mechanism 48 can slide along the second movement slide rail 42. By adjusting the position of the second limiting mechanism 48 on the second movement slide rail 42, the movement track of the manipulator assembly 43 is further controlled, and the operation difficulty of the manipulator assembly 43 is further reduced.

[0051] Further, in this embodiment, a suction device 5 is further included. The suction device 5 is used to extract the liquid in the loading device 1. It can be understood that during the water washing process, generally, the gold particles in the loading device 1 need to be washed 3 - 5 times to thoroughly remove the attached silver nitrate solution. During the repeated washing process, the solution after washing the gold particles can be removed by the suction device 5. Secondly, after the water washing is completed, there is still a lot of liquid in the loading device 1. By using the suction device 5 to extract the excessive liquid in the loading device 1, the gold particles in the loading device 1 are made to dry more easily.

[0052] It should be noted that this application is not limited to the above embodiments. The above embodiments are only examples. Embodiments with the same structure and the same function and effect as the technical idea within the technical solution scope of this application are all included in the technical scope of this application. In addition, within the scope of not departing from the main idea of this application, various deformations that can be thought of by those skilled in the art are applied to the embodiments, and other ways constructed by combining some constituent elements in the embodiments are also included in the scope of this application.
