[0019] Compared with the prior art, the application has the following beneficial effects:

[0020] 1. In the grinding process, since the silicon powder is mixed with water, it is easy to cause the wet grinding tank to generate flocculent adhesion, the pushing assembly drives the swing block to move up and down to drive the side edge of the wet grinding screen, so that the flocculent adhesion is avoided from adhering to the inner side of the wet grinding screen, and meanwhile, the setting of the arc-shaped protrusion on the side edge can improve the contact point surface of the quartz sand raw material and the grinding ball, and the overall grinding efficiency is improved;

[0021] 2. The swing block moving up and down drives the turning of the quartz sand raw material at the position not subjected to extrusion, so that the silicon powder is separated from the quartz sand in the grinding process, the silicon powder is effectively guided out, the setting of the arc-shaped protrusion on the swing block can improve the contact point surface of the quartz sand raw material and the grinding ball, and the overall grinding efficiency is improved;

[0022] 3. In the grinding process, since the water has poor flowability, the ground silicon powder cannot be quickly guided out, so that the silicon powder is accumulated in the wet grinding screen, the efficiency of the silicon powder melting into the water is affected, the content of the silicon powder in the water in the wet grinding screen is easily increased, the leakage hole of the wet grinding screen is easily blocked, the rotating assembly is driven to rotate by the linkage assembly, so that the plurality of inclined rotating sheets are driven to rotate, a directional water flow is formed, since the silicon powder generated in the grinding process melts into the water, the directional vortex flow can flow and replace the water inside and outside the wet grinding screen, the accumulation of the silicon powder in the wet grinding screen in the grinding process is avoided, and the grinding efficiency of the wet grinding screen is ensured;

[0023] 4. In the rotating process of the rotating sheet, the pushing assembly is driven to rotate, meanwhile, since the swing block is located between the positions close to the lower side of the swing space, when the rotating sheet rotates, the swing block is subjected to the repulsive force of the lower magnetic block, the swing block slides in the arc-shaped groove, meanwhile, when the swing block moves upward, the swing block is subjected to the repulsive force of the upper magnetic block in the next pushing assembly, so that the swing block moves downward, and the sliding movement of the swing block in the arc-shaped groove is ensured;

[0024] 5. During the transfer process, some difficult-to-handle impurities may be mixed in with the quartz sand. Due to their hardness and quality, these impurities will move to the bottom of the wet grinding screen and need to be cleaned, affecting the grinding efficiency. During grinding, the grinding balls will press against the upper end of the sealing plate, compressing the elastic plate and elastic column to ensure the normal grinding effect inside. After grinding for a period of time, the grinding balls will separate from the wet grinding screen, and the upper elastic plate will also recover, thereby elastically exporting the impurities accumulated in the extrusion groove and guiding them into the collection hood below, thus ensuring the collection effect of impurities and ensuring the grinding efficiency.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application.

[0037] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present application are only for the convenience of clear description, and are not used to limit the scope of the present application. The change or adjustment of the relative relationship is also considered as the implementable scope of the present application without substantial change of the technical content.

[0038] REFERENCE Figures 1-10 A high-strength electric arc quartz crucible superfine silicon powder production device, comprising: a wet grinding tank 1 and a feed inlet opening formed in the upper end of the wet grinding tank 1, a wet grinding screen 2 is arranged below the feed inlet opening, the upper end of the wet grinding screen 2 is arranged in a cylindrical shape and is fixedly connected with the lower end of the feed inlet opening, and the lower end of the wet grinding screen 2 is arranged in a semispherical shape, a plurality of leakage holes are uniformly formed in the wet grinding screen 2, and the wet grinding screen 2 is made of metal material and can withstand a large extrusion force, and the internal grinding space is spherical, which is convenient for ball milling;

[0039] An arc-shaped groove is annularly formed in the inner side of the lower end of the wet grinding screen 2, and a swing assembly 3 is arranged in the arc-shaped groove, the swing assembly 3 is used to drive the swing of the raw materials in the wet grinding screen 2, and the swing assembly 3 comprises a swing block 31, the swing block 31 is made of magnetic material and is slidingly arranged in the arc-shaped groove, and a plurality of arc-shaped protrusions are arranged on the side close to the wet grinding screen 2.

[0040] A rotating assembly 4 is annularly arranged on the outer side of the wet grinding screen 2, a pushing assembly 5 is arranged on the rotating assembly 4, and the pushing assembly 5 is used to drive the swing block 31 to move up and down in the arc-shaped groove.

[0041] In the embodiment of the application, water is introduced into the wet grinding tank 1, so that the liquid level of the water reaches the middle of the wet grinding screen 2. During grinding, the silicon powder that has been ground at the bottom will directly melt into the water and then be introduced into the wet grinding tank 1. The silicon powder will sink downward under the action of gravity, thereby facilitating the separation of the silicon powder. Then, the mixed liquid is discharged, and the silicon powder is quickly transferred, thereby improving the grinding and transferring speed. During grinding, the silicon powder is mixed with water, which is likely to cause the wet grinding tank 1 to produce flocculent adhesion. The pushing assembly 5 drives the swing block 31 to move up and down, thereby driving the side of the wet grinding screen 2, so that the flocculent adhesion is prevented from adhering to the inside of the wet grinding screen 2 and is moved downward for extrusion and dispersion.

[0042] The swing block 31 that moves up and down simultaneously drives the turning of the quartz sand raw material that is not extruded, thereby ensuring the separation of the silicon powder and the quartz sand during grinding, effectively discharging the silicon powder, dispersing the quartz sand, improving the contact surface during grinding, and improving the contact point surface of the quartz sand raw material and the grinding ball 71, thereby improving the overall grinding efficiency.

[0043] Since the quartz sand contains magnetic impurities, the magnetic impurities need to be screened after grinding. The magnetic swing block 31 magnetically attracts the magnetic impurities and adsorbs the magnetic impurities in the wet grinding screen 2, without affecting the normal grinding process, thereby reducing the impurity content in the discharged silicon powder.

[0044] The preferred technical solutions in the embodiment are as follows:

[0045] Referring to Figure 2 The feeding guide opening is in the shape of an inverted bucket, and the bottom end is fixedly connected to the upper end of the wet grinding screen 2. The wet grinding tank 1 is provided with a liquid inlet pipe at the side, and the bottom end of the wet grinding tank 1 is in the shape of an inverted circular table, thereby facilitating the discharge of the liquid.

[0046] During wet grinding, the quartz sand can be introduced through the feeding guide opening in the shape of an inverted bucket at any time, thereby ensuring the grinding efficiency. During wet grinding, the water solution is introduced through the liquid inlet pipe, so that the wet grinding tank 1 is filled with a large amount of water and is submerged to the bottom of the wet grinding screen 2. During grinding, the silicon powder is melted into the water, and the solvent containing the silicon powder is transferred through the fluidity of the water and then enters the subsequent hydrocyclone classification device. The uninterrupted grinding mode improves the production efficiency.

[0047] Referring to Figure 6, the swing assembly 3 further comprises an elastic cloth 32 and a limiting strip 33, the elastic cloth 32 is fixedly connected to the arc-shaped groove, and the width of the elastic cloth 32 is greater than the width of the arc-shaped groove, and the elastic cloth 32 deforms with the sliding of the swing piece, one end of the limiting strip 33 is fixedly connected to the upper end of the swing block 31, and the other end is fixedly connected to the top wall of the arc-shaped groove, the limiting strip 33 is used for resetting the position of the swing block 31, and the elastic cloth 32 is used to prevent the silicon powder from entering the arc-shaped groove, so that the silicon powder is accumulated, and the elastic cloth 32 can increase the area of up and down movement with the movement of the swing block 31, and improve the driving of the inner fluffy material;

[0048] With reference to Figure 7 , the rotating assembly 4 comprises a connecting rod 41, a rotating piece 42 and a cleaning piece 43, a plurality of connecting rods 41 are annularly arranged around the wet grinding screen 2, the rotating piece 42 is fixedly connected to the bottom end of the connecting rod 41, and a plurality of rotating pieces 42 are arranged in the same direction of rotation, and the rotating piece 42 forms a directional vortex when rotating, which is used to drive the movement of the liquid, the inner side of the rotating piece 42 is consistent with the shape of the edge of the wet grinding screen 2, and a plurality of cleaning pieces 43 are fixedly connected to the side of the rotating piece 42 and are in contact with the side of the wet grinding screen 2;

[0049] In the grinding process, due to the poor flowability of water, the ground silicon powder cannot be quickly guided out, so that the silicon powder is accumulated in the wet grinding screen 2, which affects the efficiency of the silicon powder melting into the water, and easily causes the content of the silicon powder in the water in the wet grinding screen 2 to be high, which easily causes the blockage of the holes of the wet grinding screen 2, the rotating assembly 4 is driven to rotate by the linkage assembly 8, so that a plurality of inclined rotating pieces 42 are driven to rotate, forming a directional water flow, and since the silicon powder generated by grinding is melted into the water, the directional vortex can flow and replace the water inside and outside the wet grinding screen 2, avoiding the accumulation of silicon powder in the wet grinding screen 2 during the grinding process, and ensuring the grinding efficiency of the wet grinding screen 2;

[0050] At the same time, due to the flow of the water, part of the silicon powder that has not been timely precipitated will be blocked outside the holes of the wet grinding screen 2, thereby affecting the flow of the water in the wet grinding screen 2, and the rotating rotating piece 42 drives a plurality of cleaning pieces 43 to rotate in contact with the wet grinding screen 2 during the rotating process, thereby cleaning the silicon powder blocked outside the wet grinding screen 2, and ensuring the flow of the water;

[0051] With reference to Figure 7 , the pushing assembly 5 comprises a first magnetic block 51 and a second magnetic block 52, the first magnetic block 51 and the second magnetic block 52 are fixedly connected to the same side of the rotating piece 42, and a swing space is arranged therebetween, the opposite poles of the ends of the first magnetic block 51 and the second magnetic block 52 are opposite, and the end of the swing block 31 close to the two magnetic blocks is also the same as the close pole, and repulsion is generated when close;

[0052] The rotating piece 42 drives the pushing assembly 5 to rotate during rotation. Meanwhile, the swing block 31 is located between the lower swing space, and when the rotating piece 42 rotates, the swing block 31 is affected by the repulsion of the lower magnetic block. The swing block 31 slides in the arc-shaped groove. When the swing block 31 moves upward, it is affected by the repulsion of the upper magnetic block in the next pushing assembly 5, thereby driving the swing block 31 to move downward, ensuring the sliding movement of the swing block 31 in the arc-shaped groove.

[0053] With reference to Figure 3 and Figure 8 , the wet grinding tank 1 is provided with a driving assembly 6. The driving assembly 6 includes a support pipe 61, a top plate 62, and a motor 63. The two support pipes 61 are vertically fixedly connected to the feeding guide, the top plate 62 is fixedly connected to the top end of the support pipe 61, and the motor 63 is fixedly connected to the middle part of the upper surface of the top plate 62, and the output end penetrates through the top plate 62.

[0054] The motor 63 is provided with a grinding assembly 7. The grinding assembly 7 includes a grinding ball 71, a rotating rod 72, and an extension rod 73. The extension rod 73 is hingedly connected to the output end of the motor 63. The motor 63 can drive the extension rod 73 to rotate. The rotating rod 72 is rotatably connected to the bottom end of the extension rod 73. The grinding ball 71 is fixedly connected to the end of the rotating rod 72.

[0055] The motor 63 drives the grinding assembly 7 to rotate and grind. When the motor 63 drives the extension rod 73 to rotate, the grinding ball 71 at the lower position is blocked. The extension rod 73 is extended to form an included angle between the extension rod 73 and the rotating rod 72, thereby changing the extrusion range of the grinding ball in the wet grinding screen 2. During grinding, the rotating rod 72 drives the grinding ball 71 to rotate, thereby effectively grinding the quartz sand in the adjustable extrusion range. The wet grinding screen 2 is effectively ground, and the quartz sand falling from the top can be stably dropped to the bottom of the wet grinding screen 2 during grinding, thereby improving the grinding efficiency.

[0056] With reference to Figure 3 and Figure 9The top plate 62 is provided with a linkage assembly 8, which is used for driving the rotating assembly 4 to rotate by the motor 63. The linkage assembly 8 comprises a toothed disc 81, a driving gear 82, a linkage rod 83 and a toothed ring 84. The toothed disc 81 is fixedly sleeved on the output end of the motor 63. The linkage rod 83 is rotatably sleeved on the support pipe 61 and has a bottom end located in the wet grinding tank 1. The driving gear 82 is fixedly connected at both ends of the linkage rod 83. The upper end of the driving gear 82 is in meshing connection with the toothed disc 81. The toothed ring 84 is sleeved on the upper end of the wet grinding screen 2 and is in meshing connection with the lower end of the driving gear 82. A plurality of connecting rods 41 are annularly fixedly connected to the bottom surface of the toothed ring 84. The toothed disc 81 is driven to rotate by the motor 63, the driving gear 82 is driven to rotate by the toothed disc 81, the toothed ring 84 below is driven to rotate, and the rotating assembly 4 is driven to rotate. The linkage assembly 8 reduces the setting of energy and improves the utilization of energy.

[0057] Referring to Figure 10 A slag outlet is arranged below the wet grinding screen 2. A collecting assembly 9 is arranged in the slag outlet and is used for collecting impurities in the wet grinding screen 2. The collecting assembly 9 comprises a collecting cover 91, an elastic column 92, a sealing piece 93 and an elastic piece 94. The collecting cover 91 is threadedly connected to the bottom end of the wet grinding screen 2. The elastic column 92 is fixedly connected to the inside of the collecting cover 91. The sealing piece 93 is a circular piece and is fixedly connected to the top end of the elastic column 92. The sealing piece 93 is used for sealing the slag outlet and is internally provided with an extrusion groove. The elastic piece 94 is fixedly connected to the upper end of the sealing piece 93 and is arranged in an arc shape upward.

[0058] Since the quartz sand will mix with some impurities which are difficult to handle during the transfer process, the impurities will be transferred to the bottom of the wet grinding screen 2 under the influence of their hardness and quality and need to be cleaned, which affects the grinding efficiency. During the grinding, the grinding balls 71 will be extruded on the upper end of the sealing piece 93 to extrude the elastic piece 94 and the elastic column 92, so that the elastic piece 94 is extruded into the extrusion groove, and the downward sealing piece 93 extrudes and seals the slag outlet, thereby ensuring the normal grinding effect inside. After a period of grinding, the water level is lowered to control the extension rod 73 to separate the grinding balls 71 from the wet grinding screen 2. The elastic column 92 elastically returns, and the elastic piece 94 at the upper end also returns, thereby elastically guiding the impurities accumulated on the upper surface of the elastic piece 94 and extruded into the groove to the inside of the collecting cover 91 below, thereby ensuring the collection effect of the impurities and the grinding efficiency.

[0059] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacements or changes according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
