[0001] The present application belongs to the technical field of magnesium metal smelting, and in particular relates to a refined dosing valve and dosing system based on silicon balls. Background Art

[0002] In the process of smelting magnesium metal, ferrosilicon pellets are formed by mixing, grinding and pressing ferrosilicon, calcined dolomite (abbreviated as calcined white) and fluorite powder in specific proportions for reduction production of magnesium metal. In order to improve the performance of the pellets as a reducing agent, manufacturers also add "silicon balls" to the raw materials for pellet preparation to increase the silicon content of the product.

[0003] In the prior art, when preparing ferrosilicon pellets for magnesium reduction production, various raw materials are collected separately in silos. A microcomputer-controlled batcher then controls the opening of valves in each silo to discharge the materials. The raw materials are then conveyed directly to a ball mill for grinding into powder. Because the physical forms of the raw materials range from large-sized lumps to small and medium-sized granules and powders, direct feeding of the materials into the ball mill can lead to uneven mixing, which can reduce grinding efficiency, increase mill wear, and cause variability in the quality of ferrosilicon pellets produced within the same batch.

Therefore, the terms describing the positional relationships in the drawings are only used for illustrative purposes and cannot be understood as limitations on this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to the specific circumstances.

[0029] The following is combined with Figure 1 To the attached Figure 6 The present application is further described in detail with reference to specific embodiments.

[0030] In the present application, a refined dispensing valve 20 based on silicon balls (hereinafter referred to as dispensing valve) is disclosed. The dispensing valve includes a first dispensing pipe 21. The internal space of the first dispensing pipe 21 is expanded along the axial direction. A stopper 211 and a discharge part 212 are stacked in sequence along the axial direction in the first dispensing pipe 21. The cross-sections of the stopper 211 and the discharge part 212 perpendicular to the axial direction of the first dispensing pipe 21 are both circular. The stopper 211 and the discharge part 212 are respectively provided with a plurality of discharge notches 213 around the center of the circle. The discharge notches 211 are stacked in sequence along the axial direction. 3 penetrates the material stopper 211 and the material discharge portion 212 respectively along the direction of gravity, so that the material can be discharged from the lower end of the first discharge pipe 21; and either the material discharge portion 212 or the material stopper 211 is fixedly connected to the inner wall of the first discharge pipe 21, and the material discharge portion 212 is rotatably connected to the material stopper 211 via a bearing 2122 (the bearing 2122 is the first bearing mentioned in this article). When the material stopper 211 rotates around the axis relative to the material discharge portion 212, the material discharge notch 213 can be opened or closed to different degrees.

[0031] Specifically, along the discharge direction of the first discharge pipe 21, the internal space of the first discharge pipe 21 is expansion-type, which helps to slow down the flow rate of the ingredients entering the discharge gap 213 and avoid blockage caused by excessive concentration of ingredients; the lower side surface of the blocking portion 211 is as close as possible to the upper side surface of the discharge portion 212, that is, the distance between the blocking portion 211 and the discharge portion 212 is not greater than the minimum particle size of the material to be unloaded, so as to avoid the material from leaking downward from the discharge gap 213 of the blocking portion 211 when the discharge gap 213 is in a completely closed state, and the discharge portion 212 and the center of the blocking portion 211 are rotatably connected by the bearing 2122 to ensure that the rotation process is smooth and avoid excessive friction resistance causing the discharge gap 213 to be difficult to open or close; a driving component is also provided on the outside of the first discharge pipe 21, and the driving component is transmission-connected to the discharge portion 212 or the blocking portion 211 for driving one of them to rotate, so as to achieve the effect of adjusting the open area of ​​the discharge gap 213.

[0032] When using the above-mentioned dosing valve, at least the following beneficial effects are achieved: the discharge notch 213 of the refined dosing valve 20 is opened to the appropriate position corresponding to the dosing for discharge, and the degree of dispersion of the dosing in the first discharging pipe 21 which is in the form of an expansion is increased, so as to prevent the dosing from being too concentrated and causing the first discharging pipe 21 to be blocked; in order to ensure smooth discharge, the discharge part 212 can be driven by the driving component to rotate relative to the blocking part 211 to gradually increase or decrease the overall opening area of ​​the discharge notch 213 according to the angle, which not only enables the discharge speed of the dosing to be precisely controlled, but also multiple discharge notches 213 form dispersed discharge channels, which reduces the probability of material accumulation, increases the smoothness of discharge, avoids the problem of excessive discharge speed and difficult control of the opening and closing process of the discharge notch 213, thereby reducing the probability of metering errors, inaccurate discharge amount and other problems, so that the dosing meets the proportion requirements.

[0033] In addition, this application also provides some more specific implementation methods to improve the above-mentioned dispensing valve.

[0034] Furthermore, in order to improve the adjustment efficiency of the discharge notch 213, in one embodiment, the above-mentioned driving assembly includes a driving motor 22 and a gear transmission mechanism 23. The driving motor 22 is fixed to the outer wall of the first discharge pipe 21 through a first flange 214 and bolts. The above-mentioned blocking portion 211 is fixedly connected to the inner wall of the first discharge pipe 21, and the discharge portion 212 is rotatably connected to the lower end of the first discharge pipe 21. The side of the discharge portion 212 away from the blocking portion 211 extends out of the lower end of the first discharge pipe 21 and is circumferentially provided with an outer gear ring 2121. The outer gear ring 2121 is transmission-connected to the driving motor 22 through the gear transmission mechanism 23.

[0035] Specifically, the first flange 214 is circumferentially arranged around the first discharge pipe 21 on the outer wall of the first discharge pipe 21 adjacent to the lower end, the drive motor 22 is fixed on the first flange 214, and the drive shaft of the drive motor 22 is vertically downward, and a plurality of sets of mutually meshing transmission gears are provided at the end of the drive shaft, wherein at least one transmission gear is fixedly connected to the drive shaft, and the transmission gear transmits the torque of the drive shaft through at least one other transmission gear meshed with the outer gear ring 2121, so that the discharge part 212 rotates around the axis relative to the blocking part 211; the above-mentioned outer gear ring 2121 is an annular external gear fixedly arranged circumferentially around the outer contour of the discharge part 212.

[0036] When using the above-mentioned dispensing valve, the driving motor 22 can drive the discharge portion 212 to rotate a corresponding angle by setting an adjustment value, so that the discharge gap 213 is quickly opened to the position required for discharge or the discharge channel of the first discharge pipe 21 is closed.

[0037] Furthermore, in order to increase the stability of the transmission structure between the drive motor 22 and the outer gear ring 2121, the above-mentioned fine dosing valve 20 also includes a second discharge pipe 24. Along the discharge direction of the first discharge pipe 21, the second discharge pipe 24 is fixedly connected to the first discharge pipe 21, and the outer gear ring 2121 is rotatably connected to the second discharge pipe 24.

[0038] Specifically, a second flange 241 is provided at the upper end of the second discharge pipe 24 around the outer wall of the second discharge pipe 24, and the second flange 241 is connected to the first flange 214 by long bolts, so that the second discharge pipe 24 is spaced apart from the lower end of the first discharge pipe 21, and the outer gear ring 2121 is located between the first discharge pipe 21 and the second discharge pipe 24; a second bearing is provided at the upper end of the second discharge pipe 24 by opening a groove, and the fixing ring of the second bearing is fixedly engaged with the groove at the upper end of the second discharge pipe 24, and the upper end of the rotating ring of the second bearing receives the lower end of the outer gear ring 2121.

[0039] When the above-mentioned dispensing valve is used, the above-mentioned structure can prevent the discharge portion 212 from moving along the direction of gravity, thereby improving the meshing stability between the outer gear ring 2121 and the gear transmission mechanism 23 .

[0040] Furthermore, the above-mentioned blocking portion 211 and the blanking portion 212 are both hollow cone-shaped, and a plurality of blanking notches 213 are respectively arranged at intervals on the side surfaces of the blocking portion 211 and the blanking portion 212 around the rotation axis of the blocking portion 211 and the blanking portion 212.

[0041] Specifically, the hollow cone-shaped blocking portion 211 and the discharge portion 212 are stacked and the apexes of the two cones point in the same direction; the inner side of the blocking portion 211 covers the outer side of the discharge portion 212 or the outer side of the blocking portion 211 covers the inner side of the discharge portion 212.

[0042] When using the above-mentioned dosing valve, the conical blocking portion 211 and the discharge portion 212 can increase the area of ​​the discharge gap 213 in the vertical direction, reduce the occupied volume of the discharge channel in the first discharge pipe 21, so as to improve the discharge efficiency and meet the discharge requirements.

[0043] Furthermore, based on the structures of the above-mentioned discharge portion 212 and the blocking portion 211 , in one embodiment, the vertices of the blocking portion 211 and the discharge portion 212 point in the opposite direction of the discharge of the first discharge pipe 21 .

[0044] Specifically, the cone apexes of the material-blocking portion 211 and the material-discharging portion 212 point upward, and the cone apexes can divert the ingredients to prevent the ingredients from being blocked at the refined ingredient valve 20 .

[0045] Furthermore, the cross-section of the material-blocking portion 211 and the material-discharging notch 213 on the side of the material-discharging portion 212 along the discharging direction of the first material-discharging pipe 21 is triangular.

[0046] Specifically, the above-mentioned cross section, i.e. the longitudinal cross section, is a triangular discharge notch 213. During the opening process, the discharge channel formed can gradually increase along the generatrix of the cone, which can effectively prevent material blockage and increase the speed of the ingredients passing through the discharge notch 213.

[0047] In order to further improve the material discharge efficiency, at least one material guide plate 2111 is arranged obliquely from top to bottom between adjacent material discharge notches 213 on the side of the material blocking portion 211 away from the material discharge portion 212, and the side of the material guide plate 2111 away from the material blocking portion 211 extends in a direction perpendicular to the axial direction of the first discharge pipe 21 and is connected to the inner wall of the discharge pipe.

[0048] When using the above-mentioned dosing valve, in the process of opening the discharge gap 213, the downwardly inclined guide plate can assist the conical material blocking portion 211 to guide and divert the material particles. Several guide plates axially evenly distributed around the side of the material blocking portion 211 divide the material into several streams and introduce them obliquely downward to the largest open area of ​​the discharge gap 213, which can slow down the vertical downward flow speed of the material to prevent a large amount of material from being blocked due to the "arch phenomenon" and improve the discharge efficiency.

[0049] Furthermore, in order to reduce the dead angle between the side of the blocking portion 211 and the blanking notch 213 , the number of the above-mentioned guide plates 2111 is set to a pair between adjacent blanking notches 213 , and the adjacent pair of guide plates 2111 are symmetrically arranged.

[0050] Specifically, between adjacent material discharge notches 213 on the material stopper 211, a pair of guide plates 2111 are symmetrically and tilted from top to bottom on the side of the material stopper 211, with the generatrix between the edges of the adjacent material discharge notches 213 as the axis of symmetry. Each pair of guide plates 2111 forms a triangular pyramid between the material stopper 211 and the inner wall of the first discharge tube 21, with one of the side edges of the triangular pyramid extending perpendicular to the axial direction of the first discharge tube 21 and facing upward. This triangular pyramid not only eliminates the dead angle between the bottom of the material stopper 211 and the inner wall of the first discharge tube 21, but also creates a diversion effect on the ingredients, directing them to the largest open area of ​​the material discharge notches 213 on both sides of the pair of guide plates 2111, further improving material discharge efficiency.

[0051] Combined with the multiple structures and features in the above embodiments, the above-mentioned fine-tuning valve 20 can perform fine-tuning on the discharge channel, which can not only adapt to a variety of ingredients, but also meet the demand for discharge efficiency in the batching process, and has good effects on improving the stability of ingredients, the accuracy of discharge quantity, and preventing blockage problems during the discharge process.

[0052] In addition, the present application also discloses a batching system, including a lower hopper 10, a fine batching valve 20, a microcomputer batcher 30 and a weighing conveyor 40, wherein a vibrator is provided on the outer wall of the lower hopper 10, and the vibrator is used to drive the hopper to vibrate with a set amplitude, so that the material passes through the discharge port at the bottom of the lower hopper 10 along the direction of gravity; the contraction end of the first discharge pipe 21 is connected to the discharge port of the lower hopper 10, and the weighing unit installed on the frame of the weighing conveyor 40 below the conveyor belt can sense the weight of the material dropped on the conveyor belt in real time, and convert the material weight value into a digital signal for display; the microcomputer batcher 30 is provided on the outer wall of the first discharge pipe 21, and the microcomputer batcher 30 is integrated with the first discharge pipe 21. A control unit and a second control unit are provided. The first control unit is electrically connected to the weighing unit and the drive motor 22 to form a control circuit. The first control unit is used to control the drive motor 22 based on the weight signal emitted by the weighing unit, so that the drive motor 22 automatically drives the material stopper 211 to rotate, thereby controlling the fine batching valve 20 to open and close and adjusting the opening area of ​​the material discharge gap 213. The second control unit is electrically connected to the weighing unit and the vibrator to form a control circuit. The second control unit is used to control the vibrator based on the weight signal emitted by the weighing unit, so that the vibrator can adjust the amplitude of the material discharge hopper 10 and control the vibration intensity of the hopper to achieve the effect of adjusting the material discharge efficiency. For example, when the microcomputer batcher 30 determines that the material amount on the conveyor belt has changed or the material amount is zero based on the signal of the weighing unit, it determines whether the material discharge hopper 10 is blocked or the opening area of ​​the material discharge gap 213 is insufficient, and controls the material discharge hopper 10 to increase the vibration intensity and / or increase the opening area of ​​the material discharge gap 213 according to the different situations, so as to restore the material discharge speed to the set value and stabilize the material discharge.

[0053] Specifically, the batching system also includes a vibrating material guide trough 50, which can be movably suspended below the discharge port of the above-mentioned fine batching valve 20, and one end of the vibrating material guide trough 50 extends obliquely to above the weighing conveyor 40, and is used to guide the batching particles discharged from the fine batching valve 20 to the weighing conveyor 40 through vibration.

[0054] Combined with the multiple structures and features in the above embodiments, the above-mentioned batching system can ensure the requirements for batching efficiency in the batching process, and can finely control the opening and closing of the batching valve 20 and the vibration of the batching hopper 10 through digital signals, so that the batching system can adaptively adjust and eliminate faults such as blockage, too fast or too slow batching speed, etc. during the batching process.

[0055] Obviously, the above embodiments of the present application are merely examples for the purpose of clearly illustrating the present application, and are not intended to limit the implementation methods of the present application. For those skilled in the art, other variations or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
