Description

Technical Field

[0001] The utility model relates to the technical field of boron carbide processing, and particularly relates to a silicon removal device for boron carbide raw materials. Background Art

[0002] Boron carbide is an important inorganic compound, commonly used in industrial and scientific research fields. It has excellent wear resistance, high temperature resistance and chemical stability. When producing boron carbide, sometimes it is necessary to remove silicon impurities in the raw materials to improve the purity and performance of boron carbide. Usually, physical separation or chemical separation methods are adopted. When using chemical separation, the boron carbide raw materials are put into an alkaline solution, and some silicon impurities can be removed, especially when silicon exists in the form of oxides. This method requires controlling the reaction conditions to avoid damaging other components.

[0003] After retrieval, a Chinese utility model patent with the authorization announcement number of CN220999255U discloses a silicon removal device for boron carbide raw materials, belonging to the technical field of silicon removal of boron carbide raw materials. Among them, it includes a processing box, a support plate is fixedly connected to the inner side of the processing box, a motor frame is fixedly connected to the top of the support plate, a driving motor is arranged inside the motor frame, and a rotating shaft is arranged at the bottom end of the output shaft of the driving motor. Its beneficial effects are that, in this silicon removal device for boron carbide raw materials, through the operation of the driving motor, the rotating shaft and the stirring frame can be driven to rotate, the boron carbide raw materials and the alkali solution can be driven to flow, the contact area between the alkali solution and the boron carbide raw materials can be increased, and the efficiency of silicon removal from the boron carbide raw materials can be guaranteed. Through the operation of the electric push rod, the mounting plate, the mounting frame and the filter frame can be driven to lift, which is convenient for taking and placing the boron carbide raw materials inside the filter frame. Through the operation of the heating plate, the temperature inside the processing box can be increased, and at a suitable temperature, the separation of silicon can be further realized, and the efficiency of impurity removal of boron carbide raw materials can be further guaranteed.

[0004] In the above patent, a motor is used to drive the stirring frame to rotate to make the alkali solution and the boron carbide raw materials fully contact. However, the boron carbide raw materials are located inside the filter frame, and the particle size of the boron carbide raw materials is small. The filter frame requires a smaller aperture to prevent the boron carbide raw materials from flowing out of the filter frame. However, the filter frame with a smaller aperture makes it difficult for the alkali solution to flow in, resulting in a lower efficiency of silicon removal from the boron carbide raw materials. Therefore, the present application provides a silicon removal device for boron carbide raw materials to meet the requirements. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a silicon removal device for boron carbide raw materials to solve the problem that the filter frame with a smaller aperture makes it difficult for the alkali solution to flow in, resulting in a lower efficiency of silicon removal from the boron carbide raw materials.

[0006] To solve the above technical problem, the utility model provides the following technical solutions:

[0007] A silicon removal device for boron carbide raw materials, comprising a base and a cylinder fixed on the base. A circular plate is arranged on the cylinder, a hydraulic rod is fixed on the base, a connecting plate is fixed on the circumferential surface of the circular plate, and the top of the hydraulic rod is fixedly connected to the bottom of the connecting plate. A liquid outlet is opened at a position near the bottom of the circumferential surface of the cylinder, and a valve is arranged on the liquid outlet. The device further comprises:

[0008] A motor, which is fixed on the top of the circular plate. The output shaft of the motor movably penetrates through the circular plate. A T-shaped spline is fixed at the bottom of the output shaft of the motor. A spline barrel is movably sleeved on the surface of the T-shaped spline. A connecting plate is fixed at the bottom of the spline barrel. A plurality of connecting covers are fixed at the bottom of the connecting plate. Upper connectors are threadedly connected to the inner walls of the plurality of connecting covers. A filter barrel is fixed at the bottom of the upper connector. A lower cover is fixed at the bottom of the filter barrel. A lower connector is threadedly connected to the inner wall of the lower cover. A roller is fixed at the bottom of the lower connector. A circular ring is fixed at the bottom of the inner wall of the cylinder. A plurality of continuous convex parts and concave parts are opened on the circular ring. During silicon removal, the roller moves along the concave part to the convex part, so that the filter barrel on the lower cover can move up and down reciprocally during rotation centered on the motor.

[0009] Preferably, a plurality of through holes are opened in the inner ring of the circular ring.

[0010] Preferably, diversion surfaces are opened on one side of the inner ring of the circular ring where the plurality of through holes are located.

[0011] Preferably, a plurality of water baffle plates are vertically fixed on the inner wall of the cylinder.

[0012] Preferably, the plurality of water baffle plates are all inclined.

[0013] Preferably, a plurality of ring plates are fixed on the inner wall of the filter barrel, and the distances between the plurality of ring plates are the same.

[0014] Preferably, a plurality of round rods are fixed between the upper connector and the lower connector.

[0015] Preferably, the plurality of round rods are parallel to the filter barrel.

[0016] Compared with the prior art, the utility model has at least the following beneficial effects:

[0017] In the above scheme, by setting the motor, the filter barrel, the roller and the circular ring, during silicon removal, the motor drives the filter barrel to rotate in the lye, and the filter barrel is in more sufficient contact with the lye. By rotating the filter barrel in the lye, the pressure of the lye on the surface of the filter barrel is greater, making it easier for the lye to enter the filter barrel and making the reaction rate faster. Secondly, during the rotation of the filter barrel, by rotating the roller on the circular ring, the filter barrel can move up and down on the top of the circular ring during rotation centered on the motor, causing the boron carbide raw materials inside the filter barrel to shake, further accelerating the reaction rate.

[0018] By setting a water baffle and an annular plate, the orientation of the included angle between the water baffle and the inner wall of the cylinder at an acute angle is opposite to the direction of the water flow. The water baffle reduces the flow of the lye, making it easier for the lye to enter the filter barrel. When the filter barrel moves up and down, the annular plate further drives the boron carbide to move, further increasing the reaction rate of the boron carbide. Brief Description of the Drawings

[0033] As Figures 1-7 shown, an embodiment of the present utility model provides a silicon removal device for boron carbide raw materials, including a base 1 and a cylinder 2 fixed on the base 1. A circular plate 4 is provided on the cylinder 2. A hydraulic rod 3 is fixed on the base 1, and the hydraulic rod 3 is connected to an external hydraulic pump. A connecting plate 8 is fixed on the circumferential surface of the circular plate 4, and the top of the hydraulic rod 3 is fixedly connected to the bottom of the connecting plate 8. A liquid outlet is provided at a position near the bottom of the circumferential surface of the cylinder 2, and a valve is provided on the liquid outlet. The device further includes:

[0034] Motor 5 is connected to an external controller through a wire, and the start and stop of motor 5 is controlled by the controller. Motor 5 is fixed on the top of circular plate 4, and the output shaft of motor 5 movably penetrates circular plate 4. A T-shaped spline 6 is fixed at the bottom of the output shaft of motor 5, and a spline cylinder 7 is movably sleeved on the surface of T-shaped spline 6. T-shaped spline 6 can move up and down on the inner wall of spline cylinder 7, and the bottom protrusion of T-shaped spline 6 plays a role of limiting, so that T-shaped spline 6 will not be separated from spline cylinder 7. A connecting plate 8 is fixed at the bottom of spline cylinder 7, and a plurality of connecting covers 9 are fixed at the bottom of connecting plate 8. The inner walls of the plurality of connecting covers 9 are all threadedly connected with upper connecting pieces 10. The upper connecting pieces A filter barrel 12 is fixed at the bottom of the component 10, and the aperture of the filter barrel 12 is smaller than the diameter of the boron carbide particles. The hydraulic rod 3 and the filter barrel 12 are staggered, which is more convenient when loading and unloading. A lower cover 14 is fixed at the bottom of the filter barrel 12, and the inner wall of the lower cover 14 is threadedly connected with the lower connecting member 11, and a roller 15 is fixed at the bottom of the lower connecting member 11. A circular ring 16 is fixed to the bottom of the inner wall of the cylinder 2, and a plurality of continuous protrusions 17 and recesses 18 are provided on the circular ring 16. When removing silicon, the roller 15 moves along the recess 18 toward the protrusion 17, so that the filter barrel 12 on the lower cover 14 can reciprocate up and down while rotating around the motor 5.

[0035] like Figure 7 As shown, in this embodiment, a plurality of through holes 19 are opened in the inner ring of the ring 16, and the alkali liquid at the inner ring of the ring 16 can flow outward from the through holes 19 and then be discharged from the liquid outlet.

[0036] like Figure 7 As shown, in this embodiment, a plurality of through holes 19 are located on one side of the inner ring of the ring 16 and are provided with a guide surface, which has a guiding function for impurities to prevent the impurities from accumulating on the inner ring of the ring 16.

[0037] like Figure 4 As shown, in this embodiment, a plurality of water retaining plates 20 are vertically fixed to the inner wall of the cylinder 2 , and the water retaining plates 20 are arranged in a circular annular array around the cylinder 2 .

[0038] like Figure 4 As shown, in this embodiment, several water baffles 20 are arranged at an angle, and the direction corresponding to the acute angle between the water baffle 20 and the cylinder 2 is opposite to the direction of flow of the alkali solution. The water baffle 20 can prevent the alkali solution from rotating in the cylinder 2, preventing the alkali solution from rotating together with the filter barrel 12, making it easier for the alkali solution to enter the filter barrel 12.

[0039] like Figure 6As shown, in this embodiment, a number of ring plates 21 are fixed to the inner wall of the filter barrel 12. The distances between the ring plates 21 are the same. During the up-and-down movement of the filter barrel 12, the filter barrel 12 drives the ring plates 21 to move up and down, and the ring plates 21 will drive the boron carbide raw materials to move up and down, enabling the boron carbide raw materials to move up and down within the filter barrel 12 over a larger range, creating a sloshing effect of the boron carbide within the filter barrel 12 and increasing the reaction rate.

[0040] As Figure 5 shown, in this embodiment, a number of round rods 13 are fixed between the upper connecting member 10 and the lower connecting member 11. Most of the force on the filter barrel 12 is borne by the round rods 13, preventing the filter barrel 12 from deforming during use.

[0041] As Figure 5 shown, in this embodiment, the number of round rods 13 is arranged in parallel with the filter barrel 12, enabling the force on the filter barrel 12 to be better dispersed on the round rods 13 and making the filter barrel 12 more stable during use.

[0042] Working principle: Before use, put the boron carbide raw materials into the filter barrel 12. Thread the filter barrel 12 to the bottom of the connection cover 9 through the upper connecting member 10. Drive the round plate 4 to move downward through the hydraulic rod 3. The round plate 4 drives the motor 5 to move downward. The motor 5 drives the T-shaped spline 6 to move downward. The T-shaped spline 6 drives the spline barrel 7 to move downward. The spline barrel 7 drives the connecting plate 8 to move downward. The connecting plate 8 drives the connection cover 9 to move downward. The connection cover 9 drives the upper connecting member 10 to move downward. The upper connecting member 10 drives the filter barrel 12 to move downward. The filter barrel 12 drives the internal boron carbide raw materials to enter the inside of the cylinder 2, causing the filter barrel 12 to enter the lye.

[0043] Start the motor 5. The motor 5 drives the filter barrel 12 to rotate through the T-shaped spline 6, the spline barrel 7, the connecting plate 8, and the connection cover 9, enabling the lye to enter the filter barrel 12 more quickly. Secondly, during the rotation of the filter barrel 12, the rollers 15 at the bottom of the lower cover 14 are on the top of the ring 16 and roll from the concave part 18 towards the convex part 17, enabling the rollers 15 to move up and down reciprocally while rotating. The rollers 15 will drive the filter barrel 12 to move up and down, driving the boron carbide inside the filter barrel 12 to slosh up and down, increasing the reaction rate. Secondly, the filter barrel 12 drives the boron carbide to slosh up and down more repeatedly through the ring plates 21.

[0044] Moreover, during the rotation of the filter barrel 12, the water flow is blocked by the water baffle 20 to prevent the water flow from rotating together with the filter barrel 12, further ensuring the reaction rate.

[0045] After desilication is completed, use the hydraulic rod 3 to push the filter barrel 12 upwards, unscrew the filter barrel 12, unscrew the lower cover 14, take out the boron carbide inside the filter barrel 12, open the valve at the liquid outlet of the cylinder 2, and replace the internal lye.

In order to enable the public to have a thorough understanding of the present utility model, specific details have been described in detail in the above preferred embodiments of the present utility model, and those skilled in the art can fully understand the present utility model without the description of these details.

[0047] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
