It is made of quartz sand, petroleum coke (or coal coke), sawdust (salt is needed to produce green silicon carbide) and other raw materials through high-temperature smelting in a resistance furnace. Silicon carbide is a semiconductor that exists in the form of extremely rare mineral moissanite in nature.

[0024] Please refer to Figures 1 to 3 The utility model is further described below in conjunction with the accompanying drawings and embodiments. The embodiment of the present application discloses a double-wing bubble turbulence device, including a mixing barrel 100, wherein:

[0025] A hollow shaft 110 is rotatably provided at the center of the bottom of the mixing barrel 100 , a first wing plate 111 and a second wing plate 112 are symmetrically provided in the middle section of the hollow shaft 110 , a plurality of hollow rods 120 are connected to the bottom end of the hollow shaft 110 , and a plurality of foaming holes 121 are provided on the hollow rods 120 . Among them, the hollow rotating shaft 110 is rotatably arranged in the mixing barrel 100, located in the middle of the mixing barrel 100, and the interior of the hollow rotating shaft 110 is hollow, and the first wing plate 111 and the second wing plate 112 are symmetrically arranged on both sides of the hollow rotating shaft 110, and the wing plate has a certain width. The shape of the wing plate can be different shapes such as triangle, square, circle, trapezoid, etc., which is mainly used to increase the mixing area in the mixing barrel 100, so that the rotation speed of the slurry is accelerated, and the bottom end of the hollow rotating shaft 110 is connected to a hollow rod 120, and a plurality of hollow rods 120 are arranged on the hollow rod 120, and a plurality of foaming holes 121 are arranged on the hollow rod 120 for emitting bubbles.

[0026] In specific work, for example, in the process of rinsing silicon carbide particles, silicon carbide slurry and water are introduced into the mixing barrel 100, and the external motor drives the hollow shaft 110 to rotate through gears or belt transmission, and the hollow shaft 110 drives the wing plate to rotate to achieve rinsing of the silicon carbide slurry. Due to the addition of the wing plate structure, the silicon carbide slurry increases the stirring area during the rinsing process, accelerates the stirring speed, and increases the collision probability between the silicon carbide particles and water, so that the acid and impurity ions attached to the surface of the silicon carbide particles are quickly separated and enter the water. At the same time, in order to increase more turbulence opportunities, a plurality of hollow rods 120 are arranged at the bottom of the hollow shaft 110, and the hollow shaft 110 is connected to the hollow rod 120. Because the hollow rod 120 is also provided with a plurality of foaming holes 121, the high-pressure gas enters the hollow rod 120 through the hollow shaft 110, and blows out countless bubbles from the foaming holes 121, and the bubbles move upward from the bottom of the mixing barrel 100 until they float to the surface. During operation, the slurry rotates in the mixing barrel 100 under the action of the wing plates, and the silicon carbide particles are subjected to horizontal force, while the bubbles blown out from the bottom move upward, so that the silicon carbide particles encounter upward bubbles while rotating horizontally, and are subjected to the upward force of the bubbles, further increasing the fluidity inside the slurry, thereby achieving a turbulent flow effect. This design makes the silicon carbide slurry more sufficient and uniform during the rinsing and stirring process, thereby improving production efficiency.

[0027] By adopting the above-mentioned device, during the rinsing process of silicon carbide slurry, the double cooperation of blowing bubbles from the foaming holes 121 and stirring by the wing plates is utilized, so that during the stirring and rotating process of the silicon carbide particles, the foaming component blows out a large number of bubbles, and the floating bubbles increase the resistance of the fluid in the mixing barrel 100 and reduce the speed. The slurry adds countless bubble vortices from bottom to top in the original rotation direction, effectively increasing the contact probability and friction between the silicon carbide particles and the water flow, thereby improving the product quality and cleaning efficiency.

[0028] In order to further optimize the wing plate and increase the turbulence, the first wing plate 111 and the second wing plate 112 are twisted with the hollow shaft 110 as the central axis to form a double helical surface. The double helical surface is a surface formed by relative twisting of the first wing plate 111 and the second wing plate 112 with the hollow shaft 110 as the central axis. For example, when the shape of the first wing plate 111 and the second wing plate 112 is a quadrilateral, the hollow shaft 110 is used as the rotating axis, the lower edge of the quadrilateral is fixed, and the upper edge is rotated relative to the lower edge by a certain angle (hereinafter referred to as the torsion angle), thereby forming a double helical surface on both sides of the hollow shaft 110. The double helical surface can ensure the movement speed of the silicon carbide slurry in the water and reduce the pressure on the hollow shaft 110 while keeping the stirring force unchanged, especially when the device is started.

[0029] Since the starting pressure is relatively high when the wings of the device are on the same plane, in order to further balance the stirring effect of the wings and the pressure of the hollow shaft 110, the twist angle 114 is 20 to 90 degrees. If the twist angle 114 is too large, the stirring force of the wings may be smaller, while if the twist angle 114 is too small, the pressure of the hollow shaft 110 during stirring is greater, that is, the twist angle of the present application is preferably 20 to 90 degrees, which can effectively balance the stirring effect of the wings and the pressure of the hollow shaft 110.

[0030] Furthermore, in order to prevent the wing plates from being deformed due to excessive rotation pressure during operation, reinforcing ribs 113 are provided on both the first wing plate 111 and the second wing plate 112. Figure 2 As shown, the reinforcing ribs 113 are arranged at the edge of the wing plate to enhance the pressure resistance of the wing plate. When the wing plate is a quadrilateral, the reinforcing ribs 113 are preferably arranged on the upper and lower sides of the wing plate; when the shape of the wing plate is semicircular or triangular, the reinforcing ribs 113 can completely surround the wing plate to protect the wing plate from deformation.

[0031] In a specific embodiment, in order to increase the flow velocity at the bottom of the mixing barrel 100 and achieve uniform foaming, one end of the plurality of hollow rods 120 is vertically connected to the hollow rotating shaft 110, and the plurality of hollow rods 120 are evenly arranged around the hollow rotating shaft 110. The plurality of hollow rods 120 are arranged at the end of the hollow rotating shaft 110, at the bottom of the mixing barrel 100, and the hollow rods 120 are evenly arranged around the hollow rotating shaft 110. Preferably, there are 2 to 12 hollow rods 120, and the rotation of the hollow rods 120 increases the movement velocity of the slurry at the bottom of the mixing barrel 100. Since the hollow rods 120 are also provided with a plurality of foaming holes 121, the foaming holes 121 are evenly spaced on the hollow rods 120, and the size of the foaming depends on the size of the foaming holes 121; the speed of the foaming depends on the pressure of the high-pressure gas, and the size and speed of the foaming can be adjusted according to work needs. During foaming, countless bubbles move upward from the bottom to form a turbulence effect, which can effectively increase the contact probability and friction between silicon carbide and water flow, thereby improving product quality and cleaning efficiency.

[0032] Furthermore, in order to allow the gas to be fully emitted from the foaming hole 121, the end of the hollow rod 120 away from the hollow shaft 110 is sealed. Among them, the end of the hollow rod 120 away from the hollow shaft 110 is sealed, which can prevent the gas from blowing out from the other end of the hollow rod 120 and affecting the foaming rate of the foaming hole 121.

[0033] In a specific embodiment, in order to prevent the slurry from flowing back into the hollow rod 120, a plurality of check valves or one-way valves are arranged in the hollow rod 120, and the check valves are arranged in alignment with the foaming holes 121. The setting of the check valves or one-way valves enables the gas to be blown out from the foaming holes 121 through the hollow rod 120 during the rinsing of the silicon carbide slurry, while the slurry cannot flow back into the hollow rod 120 from the foaming holes 121, which can effectively prevent the slurry from flowing back and blocking the foaming holes 121.

[0034] It should be noted that in the absence of a check valve or a one-way valve, when starting the device, it is necessary to start the device first and then introduce the slurry; when stopping, the slurry needs to be discharged first and then the stirring is stopped, that is, the slurry will not flow back into the hollow rod 120 without installing a check valve or a one-way valve.

[0035] In a specific embodiment, in order to match the external components, a key slot 122 is provided on the hollow shaft 110. The key slot 122 is used to match the external components. For example, the key slot 122 can be connected to an external device such as a belt, a gear, a motor, etc. to drive the hollow shaft 110 to rotate, and can also be used to install a handle for manual stirring, so that the device can work more stably and ensure the smooth progress of the production process.

[0036] In a specific embodiment, in order to further increase the collision probability of the slurry, a raised spiral structure 130 is provided on the inner wall of the mixing barrel 100, and the spiral structure 130 includes a left spiral structure or a right spiral structure, which is used to bring the upper layer of slurry to the lower layer of the mixing barrel 100. Among them, the mixing barrel 100 is provided with raised spiral structures 130 from top to bottom. When the device stirs clockwise, the spiral structure 130 is a left spiral structure, and when the device stirs counterclockwise, the spiral structure 130 is a right spiral structure. During the stirring process, the slurry is affected by the spiral structure 130, and the upper layer of slurry is brought to the lower layer. When the slurry reaches the bottom of the mixing barrel 100, it contacts the bottom of the mixing barrel 100 and then rebounds and rises back to the upper layer, thereby forming a circulating water flow, that is, realizing the change of the slurry from horizontal flow to turbulent flow. At the same time, during the process of discharging the slurry, the pressure of the discharge is increased and the discharge speed is accelerated.

[0037] Furthermore, in order to facilitate the slurry to be discharged from the mixing barrel 100, the bottom of the mixing barrel 100 is in an inverted cone shape. The inclination angle of the inverted cone can be determined according to the repose angle of the slurry, and cooperates with the spiral structure 130 in the mixing barrel 100, which is more conducive to the discharge of the slurry and prevents the slurry from remaining at the bottom of the barrel.

[0038] In a specific embodiment, in order to facilitate the introduction or export of slurry, a feed port and a water inlet are provided on the mixing barrel 100, and a discharge port is provided at the bottom of the mixing barrel 100. The feed port and the water inlet are located above the mixing barrel 100, and regulating valves are provided on the feed port and the water inlet to prevent the slurry from splashing during the feeding process, reduce the waste of slurry, and improve the accuracy of the slurry ratio. The discharge port is connected to the cone angle at the bottom of the mixing barrel 100 to facilitate the export of the slurry, so that the slurry does not remain in the mixing barrel 100 after being exported.

[0039] The above-described embodiments only express the way of equipment layout of the present application, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application; it should be pointed out that for ordinary technicians in this field, several adjustments and improvements can be made without departing from the concept of the present application, which all belong to the scope of protection of the present application; therefore, the scope of protection of the patent of this application shall be based on the attached claims.
