[0017] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] The various specific technical features in the various embodiments described in the specific implementation methods can be combined in various ways without contradiction. For example, different implementation methods can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in the present invention will not be described separately.

[0019] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the drawings, while other details that are not closely related to the present invention are omitted.

[0020] In addition, it should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the following description, the terms "first\second\..." involved are merely used to distinguish different objects, and do not indicate that the objects have the same or related points. It should be understood that the directions described by the directions nouns such as "above", "below", "inside" and "outside" involved are all directions in normal use.

[0021] In the following specific embodiments, the digestion device can be applied to the digestion of different solid ores. For example, the ore digestion device can be used to digest gold ore. For example, the ore digestion device can also be used to digest graphite ore. For ease of description, the following uses the ore digestion device for digesting graphite ore as an example to illustrate the structure and function of the digestion device.

[0022] In some embodiments, Figure 1 As shown, the digestion device 1 includes: a shell 10, a moving platform 20, a liquid injection device 30, a support 41 and a transfer device 50. The shell 10 has a receiving space 11 inside, and the receiving space 11 is used to receive other structures or devices of the digestion device 1, and the receiving space 11 can provide protection for other structures or devices of the digestion device 1 to extend the service life of other structures or devices. Moreover, during the digestion process, the acid liquid or acid gas will also be confined in the receiving space 11 and will not leak directly into the external environment, thereby reducing the harm to the external environment.

[0023] The moving platform 20 is located in the accommodating space 11 and is movably connected to the shell 10. The moving platform 20 is used to carry the test tube rack 2. The test tube rack 2 has a plurality of accommodating cavities 201 arranged at intervals. Each accommodating cavity 201 is used to accommodate a test tube. The test tube is used to accommodate a sample of graphite ore. The moving platform 20 can drive the test tube rack 2 and the test tube accommodated therein to move relative to the shell 10. The liquid injection device 30 is located in the accommodating space 11 and is movably connected to the shell 10. The liquid injection device 30 has a liquid injection port 31. The liquid injection port 31 is used to inject acid into the test tube accommodated in the test tube rack 2, thereby digesting the graphite ore in the test tube by the acid. Specifically, when the liquid injection port 31 moves to the top of the test tube, the liquid injection port 31 injects acid into the test tube. The test tube rack 2 accommodates a plurality of test tubes. By moving the liquid injection port 31 relative to the test tube rack 2, the liquid injection port 31 can be moved to the top of each test tube in turn, thereby injecting acid into each test tube.

[0024] The support platform 41 and the transfer device 50 are both located in the accommodation space 11. The support platform 41 is spaced apart from the moving platform 20. The transfer device 50 is movably connected to the housing 10 and is used to transfer the test tube rack 2 from the moving platform 20 to the support platform 41. That is, after the injection device 30 injects acid into each test tube accommodated in the test tube rack 2, the transfer device 50 transfers the test tube and the test tube rack as a whole to the support platform 41. It can be understood that after the acid is transferred into each test tube, the acid in the test tube needs a period of time to react with the graphite ore to achieve the digestion of the graphite ore. If during the reaction process, Carrying out the operation on the moving table 20 will cause the test tube rack 2 to continuously occupy the moving table 20, resulting in the inability to inject acid into the test tube contained in the next test tube rack. The embodiment of the present application provides a support platform 41 and a transfer device 50 to transfer the test tube and the test tube rack after acid injection to the support platform 41 as a whole, so that the reaction of the acid solution and the graphite ore is carried out on the support platform 41, so that the acid can be injected into the test tube contained in the next test tube rack synchronously during the reaction of the acid solution and the graphite ore, thereby improving the operating efficiency of the digestion equipment 1 and shortening the time required for the test experiment on the graphite ore.

[0025] At the same time, if Figure 2 As shown, the moving platform 20 is relative to the housing 10 along a first direction (the first direction is as shown in FIG. Figure 2 The liquid injection device 30 drives the liquid injection port to move relative to the housing 10 in the second direction (the second direction is as shown in the solid arrow in the middle). Figure 2 The first direction is not parallel to the second direction. It can be understood that the moving platform 20 in the liquid injection device provided in the embodiment of the present application can drive the test tube rack 2 to move relative to the housing 10 along the first direction (the first direction is as shown in FIG. Figure 2 The liquid injection port 31 can move relative to the housing 10 along the second direction (the second direction is as shown in the solid arrow in the middle). Figure 2The first direction and the second direction are not parallel. It can be understood that by making the test tube rack 2 and the injection port 31 move in different directions relative to the shell 10, the relative movement between the injection port 31 and the test tube rack 2 can be combined to form more different directions. Specifically, the test tube rack 2 moves in the first direction relative to the shell 10 to form a first motion vector, and the injection port 31 moves in the second direction relative to the shell 10 to form a second motion vector. Since the first motion vector and the second motion vector are not parallel, by controlling the size of the first motion vector and the size of the second motion vector, the first motion vector can be The vector sum of the quantity and the second motion vector forms a sum motion vector with various sizes and pointing in different directions, that is, by controlling the distance that the test tube rack 2 moves relative to the shell 10 along the first direction, and the distance that the injection port 31 moves relative to the shell 10 along the second direction, the injection port 31 can be suspended at different positions above the test tube rack 2, so that the injection of each test tube can be completed within one movement stroke of the test tube rack 2 and the injection port 31 without the need for the injection device 30 to perform multiple reciprocating movements, so that the injection device 30 can complete the acid injection operation faster, further improving the operation efficiency of the digestion equipment 1.

[0026] An embodiment of the present invention provides a digestion device, which includes: a shell having a storage space inside, a moving platform located in the storage space, a liquid injection device, a support platform and a transfer device, wherein the liquid injection device is used to inject acid into a test tube contained in a test tube rack on the moving platform, and the transfer device is used to transfer the test tube and the test tube rack as a whole to the support platform after the acid injection is completed. By transferring the test tube and the test tube rack after the acid injection is completed to the support platform, the reaction process between the acid and the ore contained in the test tube can be carried out on the support platform, so that the reaction process can be carried out synchronously with the liquid injection action of the test tube in the next test tube rack, thereby improving the digestion efficiency. The operation efficiency of the digestion device is improved; at the same time, the moving platform can move in a first direction relative to the shell, and the liquid injection port can move in a second direction relative to the shell, and the first direction is not parallel to the second direction. By making the test tube rack and the liquid injection port move in different directions relative to the shell, the relative movement between the liquid injection port and the test tube rack can be combined to form more different directions, so that within a movement stroke of the liquid injection and the test tube rack, the liquid injection port can be suspended above each accommodating cavity of the test tube rack, so that the liquid injection port can inject liquid into the test tubes accommodated in each accommodating cavity more quickly, thereby further improving the operation efficiency of the digestion device.

[0027] In some embodiments, making the movement directions of the test tube rack and the injection port non-parallel relative to the shell can be achieved in a variety of ways. For example, the movement forms of the test tube rack and the injection port can be different. For example, the motion table drives the test tube rack to move relative to the shell, and the injection device drives the injection port to rotate relative to the shell. For example, the movement forms of the test tube rack and the injection port can be the same, but the movement directions are different, for example, Figure 3 As shown, the moving platform 20 is used to drive the test tube rack relative to the housing 10 along a first direction (the first direction is as shown in FIG. Figure 3 The liquid injection port 31 can rotate in a second direction relative to the housing 10 (the second direction is as shown in the solid arrow in the middle). Figure 3 The test tube rack 2 and the liquid injection port 31 rotate along a curve (as shown by the dashed arrow in the middle), wherein the rotation center axis L1 of the test tube rack 2 is at a preset distance from the rotation center axis L2 of the liquid injection port 31. It can be understood that although the test tube rack 2 and the liquid injection port 31 both rotate relative to the shell 10, the rotation center axes thereof do not coincide, so that the motion trajectories thereof are two non-concentric circles or arcs, so that the motion trajectories of the test tube rack 2 and the liquid injection port 31 are not parallel, so that the motions of the test tube rack 2 and the liquid injection port 31 can be combined to form motion vectors of different sizes and directions, thereby enabling the liquid injection port 31 to hover above different test tubes accommodated in the test tube rack 2.

[0028] In some embodiments, in combination Figure 1 and Figure 4 The digestion equipment 1 also includes a covering device 40, which includes a support platform 41 and an operating part 42. The operating part 42 is rotatably connected to the shell 10. The operating part 42 is used to connect with the test tube cover and drive the test tube cover to rotate in the direction close to the support platform so that the test tube cover can seal the tube mouth of the test tube. That is, after the transfer device 50 transfers the test tube and the test tube rack as a whole to the support platform, the operating part 42 is used to cover the test tube cover with each test tube, and the test tube cover forms an interference fit with the tube mouth of each test tube to achieve the sealing of the tube mouth of each test tube. It should be noted that heat will be generated in the process of the acid liquid reacting with the graphite ore in the test tube, and the acid liquid will evaporate under the action of the heat to form Acid gas, by sealing the tube mouth of the test tube through the test tube cover, can reduce the possibility of volatile acid gas entering the storage space 11, thereby reducing the possibility of acid gas corroding other devices or structures in the storage space 11, and extending the service life of other devices or structures in the storage space 11; at the same time, the test tube cover has an air guide hole for installing an air guide tube, and the acid gas volatilized in the test tube can be discharged out of the storage space through the air guide tube, thereby reducing the possibility of the test tube bursting due to excessive internal pressure caused by the continuous retention of acid gas in the test tube, causing the air pressure in the test tube to rise, and the acid gas in the test tube can be directly discharged to facilitate the subsequent recovery and treatment of the acid gas.

[0029] At the same time, combined Figure 1 and Figure 4 The operating part 42 is rotatably connected to the shell 10, and the operating part 42 is located on the side of the support platform 41. The operating part 42 is used to drive the test tube cover to rotate between the first position and the second position. In the first position, the thickness direction of the test tube cover is perpendicular to the thickness direction of the support platform 41, and the test tube cover is located on the side of the support platform. In the second position, the thickness direction of the test tube cover is parallel to the thickness direction of the support platform, and is directly opposite to the part of the support platform 41 used to carry the test tube rack. It can be understood that when the test tube rack 2 needs to be placed on the support platform 41 or the test tube rack 2 needs to be taken out from the support platform 41, the test tube cover is rotated to the first position so that the test tube cover is in a vertical placement posture, thereby reducing the shielding effect of the test tube cover on the support platform 41, so that the test tube rack 2 can be placed on the support platform 41 or the test tube rack 2 can be taken out from the support platform 41. The test tube rack 2 is taken out, and because the test tube cover is arranged in a vertical direction, the horizontal space occupied by the test tube cover is reduced, and the horizontal size of the covering device 40 is reduced; when the test tube rack 2 is placed on the support 41 and the tube mouth of the test tube needs to be covered, the test tube cover is rotated to the second position, so that the thickness direction of the test tube cover is parallel to the thickness direction of the support 41, and the test tube cover can be directly opposite to the position of the support 41 for placing the test tube rack, and by adjusting the height of the rotation axis of the operating part 42, the tube mouth of each test tube in the test tube rack can be directly sealed with the test tube cover during the rotation process, that is, the test tube cover and the test tube can be covered by a single rotation movement of the operating part 42, which reduces the space occupied by the test tube cover, simplifies the control difficulty of the operating part 42 and speeds up the covering speed of the test tube cover.

[0030] In some embodiments, in combination Figure 1 and Figure 5 The support platform 41 has a plurality of bearing parts 43 for bearing the test tube racks 2, and the bearing parts 43 are arranged at intervals. By making the support platform 41 have a plurality of bearing parts 43, the support platform 41 can carry a plurality of test tube racks 2 at the same time. When the injection speed is greater than the reaction speed, the support platform 41 can carry a plurality of test tube racks, so that the reaction process of the acid solution and the graphite ore can be carried out synchronously with the acid injection process of the test tubes in the plurality of test tube racks, thereby further improving the operation efficiency of the digestion equipment 1; wherein, a positioning structure is arranged at a corresponding position on the outer surface of the support platform 41 to form the bearing part 43, and the positioning structure can, for example, be a clamp fixed to the support platform 41, and the positioning structure can also be a positioning column or a positioning groove arranged on the support platform 41.

[0031] Optional, such as Figure 6As shown, the number of the operating parts 42 is the same as the carrying part 43. It can be understood that each operating part 42 can be connected to a test tube cover respectively and control the test tube cover to cover the tube openings of each test tube accommodated in a test tube rack. By providing a plurality of operating parts 42, a plurality of test tube covers can be opened synchronously with the tube openings accommodated in each test tube rack, thereby further improving the operating efficiency of the digestion equipment.

[0032] Optional, combined Figure 1 and Figure 7 The support platform 41 is movably connected to the shell 10, and the bearing parts 43 are arranged at intervals along the movement direction of the support platform 41. Through the relative movement of the support platform 41 relative to the shell 10, and the arrangement direction of the bearing parts 43 is the same as the movement direction of the support platform 41, the bearing parts 43 can move relative to the operating part 42 and make the bearing parts 43 close to or away from the operating part 42, so that when the number of operating parts 42 is less than that of the bearing parts 43, the operating part 42 can cover the test tubes in the test tube racks carried by each bearing part 43 in turn, thereby reducing the structural complexity of the digestion device 1 and further improving the operating efficiency of the digestion device. Exemplary, combined with Figure 1 and Figure 7 The support 41 can rotate relative to the housing 10 (the rotation direction of the support 41 is as follows Figure 7 As shown by the arrow in the middle, multiple bearing parts 43 are arranged at intervals around the rotation center axis of the support platform 41. For the convenience of explanation, different positions on the surface of the support platform 41 are named and distinguished below. For example, the surface of the support platform 41 includes a covering position and a disassembly position. When the bearing part 43 moves to the covering position, the operating part 42 can operate the test tube cover to cover the test tube accommodated in the test tube rack on the bearing part 43. At the disassembly position, the test tube rack and the test tube after the reaction are completed can be taken out. By making the support platform 41 rotatable relative to the shell 10, each bearing part 43 can be cyclically moved between the covering position and the disassembly position. At the closing position, the operating part 42 operates the test tube cover to cover the test tube contained in the test tube rack on the carrying part 43. In the process of the carrying part 43 moving from the closing position to the disassembly position, the acid in the test tube reacts with the graphite ore. When the carrying part 43 moves to the disassembly position, the reaction between the acid and the test tube ore is completed. The test tube rack and the test tube can be taken out as a whole at this position, so that the carrying part 43 can place a new test tube rack and carry out the next cycle of movement. That is, the acid injection operation, the closing operation, the reaction process and the disassembly operation can all be completed synchronously, thereby further improving the operating efficiency of the digestion equipment.

[0033] In some embodiments, in combination Figure 1 and Figure 8The transfer device 50 includes: a movable frame 51 and at least three movable claws 52. The movable frame 51 is movably connected to the shell 10. The geometric center points of at least three movable claws 52 are not located on the same straight line, and each movable claw 52 can be slidably connected to the movable frame 51. The movement direction of each movable claw 52 is used to make the movable claws 52 approach each other or move away from each other. By making the three non-collinear movable claws 52 approach each other, the clamping of the test tube can be achieved. By making the three non-collinear movable claws 52 move away from each other, the clamped test tube can be released. It can be understood that the clamping and release of the test tube can be achieved through the relative movement of the movable claws 52. The movement of the movable frame 51 relative to the shell 10 can drive the overall movement of each movable claw 52, ​​so that the clamped test tube can be transferred between different positions, so that the test tube can be loaded into the test tube rack; at the same time, the movable claws 52 can also realize the overall transportation function of the test tube rack loaded with the test tube. The following is combined with Figure 8 , the structure of the movable claw 52 and the principle that the movable claw 52 can realize the overall transport function of the test tube rack loaded with test tubes are explained.

[0034] like Figure 8 As shown, each movable claw 52 includes: a claw body 521 and a lifting structure 522, the claw body 521 has a first end and a second end opposite to each other, the first end is slidably connected to the movable frame 51, and the claw body 521 is used to clamp the test tube; the lifting structure 522 is connected to the claw body 521 and is located at a position of the claw body 521 away from the first end, and at least part of the lifting structure 522 extends out of the side wall of the claw body 521. It can be understood that the lifting structure 522 extends from the side wall of the claw body 521, thereby extending the entirety of the claw body 521. The side wall of the claw body 521, or the lifting structure 522 extends out from the second end of the claw body 521, and the extension direction of the lifting structure 522 is not parallel to the extension direction of the claw body 521, so that part of the structure of the lifting structure 522 extends out of the side wall of the claw body 521. By moving the lifting structure 522 to the bottom of the test tube rack and abutting against the bottom surface of the test tube rack, the test tube rack containing the test tube can be lifted up as a whole. In this state, the movable claws 52 are driven to move as a whole by the movable rack 51, so that the transportation of the test tube rack can be realized.

[0035] It can be understood that the transfer device 50 realizes the transfer function of the test tube and the transfer function of the test tube rack at the same time through the same structure, thereby reducing the structural complexity of the transfer device 50, and saving the time required for moving different transfer structures when transferring the test tube and the test tube rack, thereby further improving Figure 1 The operating efficiency of the digestion equipment 1 in.

[0036] Among them, according to the different connection methods between the lifting structure 522 and the claw body 521, the relative positions of the lifting structure 522 and the claw body 521 can be different. Optionally, when the lifting structure 522 and the claw body 521 are rotatably connected, the lifting structure 522 can rotate between the distal side and the proximal side of the claw body 521, the distal side being the side in the direction in which the claw bodies 521 move away from each other, and the proximal side being the side in the direction in which the claw bodies 521 move toward each other. In this connection method, the lifting structure 522 can be moved from the lower side of the test tube rack to the bottom of the test tube rack, so that the lifting structure 522 can lift the test tube rack without providing a lifting hole for the lifting structure 522 to pass through in the test tube rack; Optionally, as Figure 8 As shown, the lifting structure 522 is fixedly connected to the claw body 521, and the lifting structure 522 extends from the side wall of the claw body 521 from the distal side of the claw body 521, and the distal side is the side opposite to the proximal side, that is, the distal side is the side that makes each claw body 521 move away from each other. By arranging the lifting structure 522 on the distal side of the claw body 521, the possibility of movement interference between the lifting structure 522 and the test tube can be further reduced in the process of clamping the test tube by the claw body 521, and the reliability of clamping the test tube is further improved. Moreover, when it is necessary to lift the test tube rack, after the lifting structure 522 passes through the lifting hole, the lifting structure 522 can be abutted against the bottom surface of the test tube rack by moving the claw bodies 521 away from each other, so that the lifting structure 522 can lift the test tube rack, that is, it is only necessary to move the claw body 521 in one direction to achieve both clamping of the test tube and lifting of the test tube rack, thereby reducing the difficulty of controlling the movable claw 52.

[0037] The embodiment of the present invention also provides a control method for a digestion device, and the control method is applied to the following figure: Figures 1 to 8 For the digestion equipment shown in any one of the drawings, the execution subject of the control method of the following embodiments may be, for example, the central processing unit of the digestion equipment. The central processing unit may control different devices or structures of the digestion equipment in different ways. For example, the central processing unit may periodically output control signals to each device or structure at a predetermined time interval, so that each device or structure performs a predetermined action at a predetermined beat. For example, the central processing unit may also obtain the state of each device or structure from a sensor, and then output corresponding control signals to the state of each device or structure according to the obtained state, so that each device or structure performs a specific function under a specific state. For example, the central processing unit may also perform comprehensive control of each device or structure according to the duration of the interval and the signal obtained by the sensor. For the sake of convenience, the control method of the digestion equipment is exemplified below by taking the central processing unit periodically outputting control signals to each device or structure as an example.

[0038] In some embodiments, Fig. 9 As shown, Fig. 9 A schematic flow chart of a control method for a first digestion device provided in an embodiment of the present invention, the control method comprising: Step S101, control the moving platform to move in a first direction relative to the shell, and control the liquid injection device to drive the liquid injection port to move in a second direction relative to the shell, and when the relative position of the liquid injection port and the test tube accommodated in the test tube rack reaches a preset position, control the liquid injection port to inject acid into the test tube.

[0039] It can be understood that the test tube rack is moved relative to the shell by the moving platform, and the injection port is driven to move relative to the shell by the injection device and the movement direction of the test tube rack is not parallel to the shell, so that the injection port and the test tube rack can move relative to each other and form a variety of different relative position relationships, and when the injection port moves to the top of the test tube accommodated in the test tube rack, the injection port is suspended above the test tube for a period of time and the acid is injected into the test tube. Optionally, after the injection port completes the injection of each test tube, the injection port and the moving platform are returned to the initial position. When the initial position is known, the relative position relationship between the injection port and the test tube rack can be controlled by controlling the displacement of the injection port and the moving platform respectively, so that the injection port can move and hover above each test tube respectively; Optionally, an in-situ sensor is provided at the injection port. When it is detected that the injection port moves to the top of the test tube, the in-situ sensor transmits a signal to the central processor, and the central processor outputs a control signal to the injection port after receiving the signal, so that the injection port responds to the control signal to inject acid into the test tube.

[0040] Step S102: Control the transfer device to transfer the test tube rack from the moving platform to the supporting platform.

[0041] Specifically, after the acid is injected into each test tube contained in the test tube rack, the test tube and the test tube rack on the moving table are transferred as a whole to the supporting platform by the transfer device, and the acid in the test tube reacts with the ore in the test tube on the supporting platform. At this time, there is no test tube rack on the moving table, and a new test tube rack can be placed on the moving table. By repeating step S101, the acid injection operation in the test tube contained in the test tube rack can be synchronously realized.

[0042] In some embodiments, the digestion device further comprises a covering device, the covering device comprising a support and an operating part, such as Fig.10 As shown, Fig.10 A flow chart of a control method for a second digestion device provided by an embodiment of the present invention, and Fig. 9 The control method shown is different in that Fig. 9 After step S102 in the control method, the control method further includes: Step S201, controlling the operating unit to drive the test tube cover to rotate in a direction close to the support platform.

[0043] That is, the test tube cover is driven to rotate by controlling the operating part to make the test tube cover seal each test tube contained in the test tube rack placed on the base. Specifically, an interference fit is formed between the test tube cover and the tube mouth of each test tube, thereby achieving sealing of the tube mouth of each test tube and reducing the possibility of acid in the test tube volatilizing into the containing space.

[0044] In some embodiments, the operating device includes a movable frame and a movable claw, such as Fig.11 As shown, Fig.11 A flow chart of a control method for a third digestion device provided in an embodiment of the present invention, and Fig. 9 The control method shown is different in that Fig. 9 Before step S101 in the control method, the control method further includes: Step S301, controlling the movable claws to move closer to each other so that the movable claws clamp the test tube that has not yet contained the acid solution.

[0045] It can be understood that the test tube is clamped by controlling the movable claws to approach each other. The test tube can contain ore in advance, or it can be an empty test tube, and the ore is placed in the test tube after the test tube is placed in the test tube rack.

[0046] Step S302: Control the movable rack to move relative to the housing to load the test tube into the test tube rack placed on the moving table.

[0047] It can be understood that after the movable claws clamp the test tube, the movable frame drives the movable claws to move as a whole, thereby driving the test tube to move relative to the shell, so that the test tube can be loaded into the test tube rack. For example, the movable frame drives the movable claws to clamp the test tube and move it to the top of the test tube rack, and then drives the movable claws to move downward to place the test tube into the test tube rack; after the test tube is placed in the test tube rack, the movable claws are controlled to move away from each other so that the movable claws release their grip on the test tube, thereby separating the movable claws from the test tube to complete the transfer of the test tube, and enabling the movable claws to clamp and transfer the next test tube.

[0048] The above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention.
