Description

Technical Field

[0001] The invention patent relates to fire assay detection, and specifically to a batching and mixing device. Background Art

[0002] Fire assay is a classic method for determining precious metals such as gold and silver. It still plays an irreplaceable role in modern chemical analysis, especially for the determination of gold content in high-gold raw materials or pure gold. Its precision and accuracy are beyond the reach of other direct determination methods. In the process of fire assay analysis, before sending the sample into the smelting furnace, the powdered sample to be tested and the flux need to be stirred and mixed so that the material can react quickly and fully in the crucible.

[0003] The technical solution disclosed in the patent document entitled "A Fire Assay Ingredient Mixing Device" (document number CN221933657U, hereinafter referred to as Document 1) includes a pot body, a cover body and a stirring mechanism; the stirring mechanism is provided with a motor located at the cover body away from the second opening end, the working end of the motor is coaxially connected to one end of a rotating rod, the other end of the rotating rod penetrates the cover body and extends into the pot body and is connected to a stirring component. The ingredients for the fire assay are placed in the pot body, and the cover body forms a sealed space inside. Controlling the first motor to work can drive the stirring component to rotate along the axis of the rotating rod, thereby stirring the ingredients for the fire assay to fully mix the components.

[0004] The technical solution disclosed in the patent document entitled "A stirring device for fire assay" (document number CN221514156U, hereinafter referred to as document 2) includes a workbench, a top plate is installed above the workbench, multiple support rods, two electric push rods and an inspection mold are installed between the workbench and the top plate, a driving motor is installed on the top of the top plate, a gear bin is installed at the bottom of the top plate, a driving wheel and multiple driven wheels are installed inside the gear bin, a stirring rod is installed at the bottom of the driving wheel and the multiple driven wheels, and a sealing ring is installed at the bottom of the gear bin. The driving motor drives the driving wheel and the multiple driven wheels to rotate, so that the stirring rod mixes and stirs the sample to be inspected and the covering agent in the inspection mold.

[0005] The technical solution disclosed in the patent document entitled "A closed automatic sample stirring machine for fire assay" (document number CN107998951B, hereinafter referred to as document 3) includes a bracket; a lower box body, which rotates relative to the bracket through a first rotating shaft and a second rotating shaft fixed on both sides, one side of the lower box body is hinged to the upper box body through a hinge, and the other side is connected through a locking device; the upper box body includes: an elastic layer that seals the opening of the crucible, a hard support plate that fixes the elastic layer, and the support plate contacts the bottom surface of the upper box body through an inflatable and deflable air bag with a valve; the lower box body is provided with a crucible groove for placing the crucible. Through the air bag and elastic layer embedded in the upper box body, the elastic layer squeezes the opening of the sealed crucible to rotate and mix the material.

[0006] At present, the mixing operation of mixing the sample and the flux is mostly achieved by stirring the crucible with a stirring rod. When this method is used, after the sample and the flux are mixed, some materials often adhere to the stirring rod. Although these materials can be manually cleaned back into the crucible, it is extremely difficult to completely clean them up and it is easy to cause the materials to scatter outside the crucible, which will affect the final test results of the sample. Although the setting of the stirring rod is cancelled in the technical solution of Document 3, the materials in the crucible are mixed by the rotation action, but after the equipment rotates, the elastic layer as the sealing part of the open end of the crucible will also adhere to the sample and there will be the same material adhesion problem. Summary of the invention

[0007] The present invention provides a batching and mixing device. After the mixing operation is completed, the sample and the flux are completely retained in the crucible without loss, thereby ensuring the accuracy of subsequent detection results.

[0008] In order to achieve the above-mentioned purpose, the technical solution adopted is: a batching and mixing device, including a frame, on which is arranged a supporting frame for supporting a crucible with its opening facing upward, and a sealing film is arranged on the frame above the supporting position of the crucible, and when the crucible moves upward with the supporting frame to the sealing film position where the film surface is in a flat position and the film is sealed to the pot mouth of the crucible, the driving shaft drives the frame to rotate in the plumb plane; when the frame stops rotating and resets to the stop position with the pot mouth of the crucible facing upward, the cutting unit cuts a film slice on the sealing film to seal the pot mouth area of ​​the crucible, and the film tamping unit pushes the film slice to move into the crucible.

[0009] Compared with the prior art, the technical effect of the present invention is as follows: the pot mouth of the crucible is sealed with a sealing film, and after the material is turned over and mixed, the cutting unit can cut off the film body that blocks the pot mouth area of ​​the crucible, and the film tamping unit pushes it into the crucible. Part of the material is attached to the cut film body and does not need to be taken out of the crucible. It can be melted together with the material, thereby avoiding the loss of the original material in the crucible. The molten film body will not affect the subsequent detection results, thereby ensuring the accuracy of the detection results. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following is combined with Figure 1-13 And related contents, the present invention is further described in detail:

[0024] A batching and mixing device comprises a frame 10, on which a supporting frame 20 for supporting a crucible A with its opening facing upward is arranged, and a sealing film 30 is arranged on the frame 10 above the supporting position of the crucible A. When the crucible A moves upward along with the supporting frame 20 to the position of the sealing film 30 where the film surface is in a flat position and the film is sealed against the pot mouth of the crucible A, a driving shaft 40 drives the frame 10 to rotate in a plumb plane; when the frame 10 stops rotating and resets to the stop position where the pot mouth of the crucible A faces upward, a cutting unit 50 cuts a film slice B on the sealing film 30 to seal the pot mouth area of ​​the crucible A, and a film tamping unit 60 pushes the film slice B to move into the crucible A.

[0025] In the above scheme, when the sample and the flux need to be mixed, the crucible A containing the sample and the flux is placed on the bracket 20 with the opening facing upward, and the bracket 20 is used to support the crucible A. Then, when the crucible A moves upward with the supporting frame 20 to the position of the sealing film 30 where the film surface is in a flat position and the film is sealed at the pot mouth of the crucible A, the driving shaft 40 drives the frame 10 to rotate in the plumb plane, so that the crucible A rotates synchronously with the frame 10 to mix the materials in the crucible A. After the mixing is completed, when the frame 10 stops rotating and resets to the stop position with the pot mouth of the crucible A facing upward, the cutting unit 50 cuts a film slice B on the sealing film 30 to block the pot mouth area of ​​the crucible A (the film slice B serves as the open cover of the crucible A. During the turning and mixing process of the crucible A, a small amount of material is attached to the inner side of the film slice B), and the film tamping unit 60 is used to push the film slice B to move into the crucible A, so that the film slice B and the material are mixed in the crucible A. In the subsequent operation, the film slice B with the material attached can be melted in the crucible A together with the material, the material on the film slice B will not be lost, and the melted film body will not affect the subsequent detection results, thereby ensuring the accuracy of the detection results.

[0026] It should be noted that the support frame 20 is driven by a power unit to move up and down (it can be driven by a cylinder or an electric cylinder). When the crucible A placed on the support frame 20 rotates, the support frame 20 and the sealing film 30 respectively limit the bottom and the mouth of the crucible A in both directions. When the crucible A is in an inverted posture, the crucible A will not fall from the support frame 20. In this solution, a clamp can also be provided on the support frame 20, and the crucible A can be directly clamped and fixed by the clamp to prevent the crucible A from falling from the support frame 20 when it is turned over.

[0027] As a preferred solution, the frame 10 includes a base plate 11 and a base frame 12, on which a power mechanism is arranged. A drive shaft 40 connected to the power mechanism and located in the horizontal direction is connected to the base plate 11. The sealing film 30, the cutting unit 50, the film tamping unit 60 and the supporting frame 20 are arranged on the same side of the base plate 11. The base frame 12 is used as a base body, on which a power mechanism is arranged. One end of the drive shaft 40 is connected to the power mechanism, and the other end is connected to the base plate 11. The drive shaft 40 is driven to rotate by the power mechanism, so that the base plate 11 connected to the structure arranged thereon can rotate in the plumb plane.

[0028] Furthermore, combined with Figure 3 , Figure 4 as well as Figure 5As shown, the sealing film winding roller 31A and the sealing film unwinding roller 31B are arranged horizontally and spaced apart on the side of the support frame 20 on the substrate 11. The sealing film 30 is transported from the sealing film unwinding roller 31B to the sealing film winding roller 31A and the width of the sealing film 30 is greater than the pot mouth diameter of the crucible A. When the crucible A is in the supporting position on the support frame 20, the pot mouth of the crucible A and the film body between the sealing film winding and unwinding rollers 31A and 31B are arranged relatively spaced apart. After the material mixing operation in the crucible A is completed, the sealing film unwinding roller 31B with the sealing film 30 wound around it transports the film body thereon to the sealing film winding roller 31A along a prescribed path, so that the complete film body is transported to the upper side of the supporting position of the crucible A, so as to perform the sealing and mixing operation on the subsequent crucible A. The incomplete film segment on the sealing film 30 after the film slice B has been cut off by the cutting unit 50 is wound and recovered by the sealing film winding roller 31A.

[0029] It is necessary to explain that, in order to ensure that the sealing film 30 is in a taut state and not loose, the sealing film reeling and unreeling rollers 31A and 31B can be controlled to rotate by a stepping motor and will not rotate freely.

[0030] As a preferred solution, an annular pressure ring 70 is provided on the substrate 11 above the sealing film 30. The lower end surface of the pressure ring 70, the sealing film 30, and the pot mouth end surface of the crucible A are arranged parallel to each other. When the crucible A moves upward with the support frame 20 to the diaphragm of the sealing film 30 and seals the pot mouth of the crucible A, the pot mouth end surface of the crucible A presses against the sealing film 30 and forms a pressing fit with the lower end surface of the pressure ring 70. The pressure ring 70 can stop and limit the crucible A, and the support frame 20 can stop and limit the bottom of the crucible A. The two cooperate with each other to ensure that the sealed crucible A can rotate stably and synchronously with the substrate 11. In addition, the pot mouth end surface of the crucible A and the pressure ring 70 clamp the sealing film 30 to ensure that the sealing film 30 effectively blocks the pot mouth of the crucible A to prevent the material in the crucible A from leaking when the crucible A rotates. Here, the lower end surface of the edge pressing ring 70 can be made of a silicone material, which has a certain elastic deformation ability and can better adapt to the uneven pot mouth of the crucible A for tight sealing.

[0031] In order to cut a film slice B for sealing the pot mouth area of ​​the crucible A on the sealing film 30, a movable seat 80 is arranged on the substrate 11 above the sealing film 30, and the lower end face of the movable seat 80 is connected to a ring-shaped tool 51 and the lower end pipe mouth of the tool 51 constitutes an annular blade 511, the blade 511 is arranged coaxially with the pressure ring 70 and the diameter of the blade 511 is larger than the outer diameter of the pressure ring 70, the crank connecting rod mechanism 81 drives the movable seat 80 to move along the ring core direction of the tool 51 to move closer to or away from the crucible A, and when the substrate 11 is reset to the stop position, the tool 51 moves toward the crucible A and the tool 51 cuts a film slice B on the sealing film 30.

[0032] In this solution, since the cutter 51 is annular and arranged around the outer periphery of the pressure ring 70, the pot mouth end surface of the crucible A is pressed against the lower end surface of the pressure ring 70. The crank connecting rod mechanism 81 drives the movable seat 80 and the cutter 51 thereon to move toward the crucible A, and the blade 511 on the lower end surface of the cutter 51 cuts a film slice B covering the pot mouth area of ​​the crucible A on the sealing film 30, thereby separating the film slice B attached with part of the material in the crucible A from the sealing film 30 as a whole, so that the subsequent film tamping unit 60 can push the film slice B into the crucible A alone.

[0033] Furthermore, in order to ensure that the cutter 51 can stably cut the film slice B on the sealing film 30, the lower end surface of the movable seat 80 is connected to an upper pressure ring 100A through an elastic connector 90. The upper pressure ring 100A is coaxially arranged with the cutter 51 and is adjacent to and surrounded by the outer periphery of the cutter 50. The elastic force provided by the elastic connector 100A drives the upper pressure ring 100A to move away from the movable seat 80 along its ring core direction. A lower pressure ring 100B is also provided on the substrate 11. The upper pressure ring 100A and the lower pressure ring 100B are arranged coaxially and are placed on the upper and lower sides of the sealing film 30. When the upper pressure ring 100A is in the initial position separated from the flat sealing film 30, the height of the blade 511 of the tool 51 is located above the lower end surface of the upper pressure ring 100A and the height of the lower end surface of the pressure ring 70 is located below the blade 511; when the tool 51 moves toward the crucible A, the upper pressure ring 100A presses against the sealing film 30 and is pressed tightly against the upper end surface of the lower pressure ring 100B.

[0034] Combination Fig.10 , Fig.11 as well as Fig.12 As shown: the pot mouth of the crucible A is in a state of pressing the sealing film 30 to the lower end surface of the edge pressure ring 70. When the crank connecting rod mechanism 81 drives the movable seat 80 to move downward, the upper pressure ring 100A moves downward synchronously with the movable seat 80. Before the tool 51 contacts the sealing film 30, the upper pressure ring 100A first presses against the sealing film 30 and cooperates with the lower pressure ring 100B to clamp the sealing film 30. Then the tool 51 continues to move downward and cuts the sealing film 30 at a position close to the inner circumference of the upper and lower pressure rings 100A and 100B. In this solution, the upper and lower pressure rings 100A and 100B are used to clamp the sealing film 30 to ensure that the sealing film 30 is effectively tensioned before cutting, thereby avoiding the situation where the sealing film 30 becomes loose and causes cutting failure during the process of the blade 511 of the tool 51 cutting the sealing film 30 in a push-type manner.

[0035] It should be noted that, under the setting of the elastic connector 90, after the upper pressure ring 100A is pressed against the lower pressure ring 100B, the upper pressure ring 100A cannot continue to move downward, and the movable seat 80 will drive the cutter 51 to continue to move downward. During the process, the elastic connector 90 will elastically shrink under the relative squeezing between the movable seat 80 and the upper pressure ring 100A, so as not to affect the continued downward movement of the movable seat 80, so that the blade 511 of the cutter 51 cuts the sealing film 30. The elastic force of the elastic connector 90 can ensure that the sealing film 30 is effectively clamped on the lower pressure ring 100B by the upper pressure ring 100A.

[0036] As a preferred solution, the elastic connector 90 includes a guide shaft 91, the axis of which is parallel to the ring core of the tool 51, the lower end of which is connected to the upper pressure ring 100A, the guide shaft 91 passes through the guide sleeve 92 on the movable seat 80 and forms a guide sliding fit therewith, a compression spring 93 is sleeved on the shaft body of the guide shaft 91 located between the movable seat 80 and the upper pressure ring 100A, and the upper end of the guide shaft 91 is connected to a limiting cap 94, the size of which is larger than the aperture of the guide sleeve 92. The guide shaft 91 connected to the upper pressure ring 100A cooperates with the guide sleeve 92 on the movable seat 80, and the upper pressure ring 100A can move relative to the movable seat 80 along the axis of the guide shaft 91, and when the upper pressure ring 100A pushes against the lower pressure ring 100B, the compression spring 93 will be compressed and deformed, thereby providing elastic force to drive the upper pressure ring 100A to press the sealing film 30.

[0037] The setting of the limiting cap 94 can prevent the guide shaft 81 from slipping out of the guide sleeve 92 on the movable seat 80 from top to bottom, thereby ensuring a stable connection between the upper pressure ring 100A and the movable seat 80.

[0038] Further combined with Figure 8-13 As shown, a tamping rod 61 is connected to the movable seat 80, the tamping rod 61 is located at the center of the pressure ring 70, and the rod core of the tamping rod 61 is arranged coaxially with the ring core of the tool 51, and a disc-shaped tamping head 62 is connected to the lower end of the tamping rod 61. When the movable seat 80 is in the initial position, the tamping head 62 is located above the pressure ring 70; when the movable seat 80 is in the terminal position when the tool 51 cuts the film slice B on the sealing film 30, the tamping head 62 is located below the pressure ring 70.

[0039] When the cutter 51 cuts the film slice B, the crank connecting rod mechanism 81 drives the movable seat 51 to continue to move downward, and the tamping rod 61 and the tamping head 62 located at the center of the pressure ring 70 continue to move downward with the movable seat 80, and the tamping head 62 will push the cut film slice B into the crucible A, thereby tamping the film slice B with part of the material attached into the crucible A, ensuring that all the materials remain in the crucible A. In this solution, the sealing film 30 has a certain toughness. Under normal circumstances, when the film slice B is in a state of being clamped by the pressure ring 70 and the end face of the pot mouth of the crucible A, when the tamping head 62 pushes the film slice B, the edge of the film slice B can be pulled out from between the pressure ring 70 and the end face of the pot mouth of the crucible A, without affecting the tamping head 62 to tamp the film slice B into the crucible A. Of course, the support frame 20 can also be controlled in advance to drive the crucible A to separate from the edge pressure ring 70 to avoid the situation where the edge pressure ring 70 and the pot mouth of the crucible A have too strong a clamping force on the film slice B, causing the film slice B to be clamped and difficult to be pushed into the crucible A.

[0040] As a preferred solution, Fig. 9 As shown, a connecting platform 110 is provided on the substrate 11, and the blank holder 70 is connected to the connecting platform 110 through a connecting rod 71. The movable seat 80 is located below the connecting platform 110, and a corresponding through hole 82 is provided on the movable seat 80 for the rod body of the connecting rod 71 to freely pass through. When the movable seat 80 moves up and down, the blank holder 70 will not interfere with the movable seat 80, and the blank holder 70 always maintains a fixed position relative to the substrate 11.

[0041] In addition, the movable seat 80 is connected with a limit guide post 120 extending upward, the column core direction of the limit guide post 120 is parallel to the ring core direction of the tool 51, and the limit guide post 120 is inserted through the guide sleeve 121 on the connecting platform 110 and forms a guide sliding fit with it. Through the guide fit between the limit guide post 120 and the guide sleeve 121, it is ensured that the movable seat 80 can move back and forth along the ring core direction of the tool 51 under the drive of the crank connecting rod mechanism 81, so as to realize the cutting action of the tool 51, the tamping action or the resetting action of the tamping head 62.

[0042] Combination Figure 1 and Figure 2 As shown, a protection box 13 with an open bottom is provided on the substrate 11, and the protection box 13 is provided outside the sealing film 30, the cutting unit 50 and the film pounding unit 60, and the support frame 20 is located outside the protection box 13. The protection box 13 is provided for the purpose of protecting the overall structure on the substrate 11, and the bottom of the protection box 13 is open, which does not affect the placement or removal of the crucible A.

[0043] Finally, it should be noted that the sealing film unwinding roller 31B, the sealing film winding roller 31A, the support frame 20 or the crank connecting rod mechanism 81 on the substrate 11 require power to drive the operation. Considering that the substrate 11 is a rotating part, a corresponding power unit can be arranged on the substrate 11 to drive the corresponding components on the substrate 11 to operate, and a battery can be directly arranged on the substrate 11 to power the power unit, so as to avoid the situation where the power supply wire and the drive shaft 40 are entangled or entangled when the substrate 11 rotates. The above situation can also be avoided by using a brush to energize. Of course, the above problem can also be avoided by controlling the maximum rotation angle of the substrate 11 and the length of the external power supply wire.
