[0027] As Figure 1 shown, an embodiment of the present utility model provides a boron carbide slurry drying device, including a microwave dryer 1. A support mechanism 9 is arranged on one side of the microwave dryer 1. A material box 6 is arranged on the top of the support mechanism 9. The support mechanism 9 includes a support plate 91 fixedly connected to the side of the microwave dryer 1. A compensation cylinder 81 is fixed on the support plate 91. A support inclined rod 92 is fixedly connected to the bottom of the support plate 91. One end of the support inclined rod 92 away from the compensation cylinder 81 is fixedly connected to one side of the microwave dryer 1. By fixedly connecting the support plate 91 to the side of the microwave dryer 1 and the bottom of the compensation cylinder 81, the compensation cylinder 81 can be better supported and fixed on one side of the microwave dryer 1, thereby improving the practicability of the device.

[0028] As Figure 3As shown, one side of the material box 6 is fixedly connected with a bracket, and a pre-drying mechanism 4 is arranged at the top of the bracket. The pre-drying mechanism 4 includes a motor 41 installed at the top of the bracket. A bearing seat 2 is installed outside the motor 41. The output end of the motor 41 is fixed with an electromagnetic drying roller 42. One side of the material box 6 close to the microwave dryer 1 is fixedly connected with a support rod 7. The top of the support rod 7 is fixedly connected with a first scraper 45. The side surface of the first scraper 45 is attached to the circumferential surface of the electromagnetic drying roller 42. The first scraper 45 is inclined. Two second scrapers 48 are fixed on the side surface of the first scraper 45. The side surface of the second scraper 48 is attached to the end surface of the electromagnetic drying roller 42. The first scraper 45 is located above the conveyor belt of the microwave dryer 1. During drying, boron carbide slurry is stored inside the material box 6. The bottom of the electromagnetic drying roller 42 is in contact with the boron carbide slurry inside the material box 6. When it is necessary to pre-dry the boron carbide slurry, the motor 41 drives the electromagnetic drying roller 42 fixedly connected to the output end to rotate. At this time, the electromagnetic drying roller 42 contacts the boron carbide slurry inside the material box 6 and heats it, so that the heated boron carbide slurry adheres to the surface of the electromagnetic drying roller 42, thereby driving the boron carbide slurry adhering to the surface of the electromagnetic drying roller 42 to rotate to the first scraper 45 and the second scraper 48. Then, the boron carbide slurry adhering to the surface of the electromagnetic drying roller 42 is scraped off onto the first scraper 45 and the second scraper 48 by the rotation of the electromagnetic drying roller 42. Then, the boron carbide slurry scraped off is conveyed to the microwave dryer 1 by the inclination angles of the first scraper 45 and the second scraper 48 for thorough drying, thus solving the problem that in the existing drying process of boron carbide slurry, first the boron carbide slurry is heated into large lumps by heating, then the large lump materials are crushed into small lump materials, and then the small lump materials are conveyed into the microwave dryer 1 by a conveyor belt for thorough drying. The above drying process is cumbersome and takes a long time, thus affecting the drying efficiency, and thereby improving the practicability of the device.

[0029] As Figure 3As shown, a plurality of first V-shaped recesses 43 are formed on the surface of the electromagnetic drying roller 42, and a plurality of first V-shaped protrusions 44 are provided on the surface of the electromagnetic drying roller 42. The first V-shaped recesses 43 are located between two adjacent first V-shaped protrusions 44. Both the first V-shaped protrusions 44 and the first V-shaped recesses 43 are in contact with the boron carbide slurry in the material box 6. A plurality of second V-shaped protrusions 46 and a plurality of second V-shaped recesses 47 are provided on the surface of the first scraper 45. The second V-shaped recesses 47 are located between two adjacent second V-shaped protrusions 46. The side surface of the second V-shaped protrusion 46 is attached to the surface of the first V-shaped protrusion 44, and the side surface of the second V-shaped recess 47 is attached to the inner wall of the first V-shaped recess 43. By providing a plurality of first V-shaped recesses 43 and a plurality of first V-shaped protrusions 44 on the surface of the electromagnetic drying roller 42, the contact area between the surface of the electromagnetic drying roller 42 and the boron carbide slurry in the material box 6 can be made larger, so that the working efficiency can be greatly improved when the electromagnetic drying roller 42 pre-dries the boron carbide slurry. By providing a plurality of second V-shaped protrusions 46 and a plurality of second V-shaped recesses 47 on the surface of the first scraper 45, it can be better adapted to the first V-shaped recesses 43 and the plurality of first V-shaped protrusions 44 provided on the surface of the electromagnetic drying roller 42, so that the boron carbide slurry attached to the surface of the electromagnetic drying roller 42 can be better scraped off. Moreover, by using the second V-shaped protrusions 46 to break the scraped boron carbide slurry into small pieces and convey it along the surface of the second V-shaped recess 47, the boron carbide slurry scraped off during pre-drying can be better broken into a plurality of small lump shapes, thereby improving the practicability of the device.

[0030] As Figure 1 shown, a baffle 5 is commonly connected to the first scraper 45 and the second scraper 48. The number of baffles 5 is two, and the electromagnetic drying roller 42 is located between the two baffles 5. By commonly connecting a baffle 5 to the first scraper 45 and the second scraper 48, the boron carbide slurry can be better blocked when it is conveyed along the first scraper 45 and the second scraper 48, preventing the boron carbide slurry from falling out of the first scraper 45 and the second scraper 48 during the conveying process.

[0031] As Figure 2As shown, a discharging mechanism 3 is provided on the conveyor belt of the microwave dryer 1. The discharging mechanism 3 includes a connecting rod 31 fixedly connected to the side of the baffle 5 away from the electromagnetic drying roller 42. The discharging mechanism 3 includes that support blocks 32 and elastic pieces 36 are respectively fixedly connected to the bottom of the connecting rod 31. A soft plate 33 is fixedly connected to the bottom of the support block 32. The soft plate 33 is located below the first scraper 45. A hard plate 34 is fixedly connected to the side of the soft plate 33 away from the electromagnetic drying roller 42. A rubber plate 35 is jointly connected to the top of the hard plate 34 and the soft plate 33. The top of the rubber plate 35 is fixedly connected to the bottom of the connecting rod 31. The bottom of the elastic piece 36 is fixedly connected to the top of the hard plate 34. The side of the elastic piece 36 is fixedly connected to the side of the rubber plate 35. A plurality of connecting frames 38 are fixed to the bottom of the hard plate 34. An eccentric wheel 37 is rotatably connected inside the connecting frame 38. When the first scraper 45 and the second scraper 48 convey the boron carbide slurry onto the soft plate 33, the conveyor belt drives the eccentric wheel 37 to rotate, and then the eccentric wheel 37 drives the connecting frame 38 to vibrate up and down, and then the connecting frame 38 drives the hard plate 34 to vibrate up and down. Due to the deformation characteristics of the soft plate 33, the hard plate 34 drives the soft plate 33 to deform and vibrate, so that the boron carbide slurry conveyed onto the soft plate 33 and the hard plate 34 vibrates, so that the agglomerated boron carbide slurry can be better vibrated and broken into small agglomerates, so that the small agglomerated boron carbide slurry can be better dried. The elastic piece 36 can better enable the soft plate 33 and the hard plate 34 to reset during the vibration, so as to ensure that the eccentric wheel 37 is always in contact with the conveyor belt, thereby improving the practicability of the device.

[0032] As Figure 1 shown, the number of the eccentric wheels 37 is two, and the two eccentric wheels 37 are symmetrically arranged with the vertical plane passing through the center of the hard plate 34 as the symmetry plane. By arranging two eccentric wheels 37, the hard plate 34 can be better balanced during the vibration, which is beneficial to improving the stability during rotation, thereby improving the practicability of the device.

[0033] As Figure 4 shown, a compensation mechanism 8 is provided at the bottom of the material box 6. The compensation mechanism 8 includes a compensation cylinder 81 fixedly connected to the bottom of the material box 6. A telescopic rod 82 is installed at the bottom of the compensation cylinder 81. The telescopic end of the telescopic rod 82 movably penetrates through the compensation cylinder 81 and is fixed with a piston 83. The piston 83 is slidably connected inside the compensation cylinder 81. The telescopic rod 82 drives the piston 83 to move up and down inside the compensation cylinder 81, so that the piston 83 pushes the boron carbide slurry upward, so that the boron carbide slurry can be better compensated when the liquid level of the boron carbide slurry in the material box 6 drops and cannot contact the electromagnetic drying roller 42 after being dried for a part, which is beneficial to improving the working efficiency, thereby improving the practicability of the device.

[0034] As Figure 1As shown, one end of the material box 6 away from the electromagnetic drying roller 42 extends outward; through the end of the material box 6 away from the electromagnetic drying roller 42 extending outward; it can better add materials to the inside of the material box 6 through the end extending outward, thereby improving the practicability of the device.

[0035] Working principle:

[0036] When it is necessary to preheat the boron carbide slurry in the material box 6, the electromagnetic drying roller 42 fixedly connected to the output end is driven to rotate by the motor 41. At this time, the electromagnetic drying roller 42 contacts the boron carbide slurry in the material box 6 and heats it, so that the heated boron carbide slurry adheres to the surface of the electromagnetic drying roller 42, thereby driving the boron carbide slurry adhering to the surface of the electromagnetic drying roller 42 to rotate to the first scraper 45 and the second scraper 48. Then, the boron carbide slurry adhering to the surface of the electromagnetic drying roller 42 is scraped onto the first scraper 45 and the second scraper 48 by the rotation of the electromagnetic drying roller 42. By providing a plurality of first V-shaped recesses 43 and a plurality of first V-shaped protrusions 44 on the surface of the electromagnetic drying roller 42, it can better increase the contact area between the surface of the electromagnetic drying roller 42 and the boron carbide slurry in the material box 6. Therefore, when the electromagnetic drying roller 42 pre-dries the boron carbide slurry, the working efficiency can be greatly improved. By providing a plurality of second V-shaped protrusions 46 and a plurality of second V-shaped recesses 47 on the surface of the first scraper 45, it can better match the first V-shaped recesses 43 and the plurality of first V-shaped protrusions 44 provided on the surface of the electromagnetic drying roller 42, so as to better scrape the boron carbide slurry adhering to the surface of the electromagnetic drying roller 42. Furthermore, the boron carbide slurry scraped off is broken into small pieces by the second V-shaped protrusions 46 and conveyed along the surface of the second V-shaped recesses 47. Then, the boron carbide slurry scraped off is conveyed to the microwave dryer 1 by the inclination angles of the first scraper 45 and the second scraper 48 for thorough drying. When the boron carbide slurry in the material box 6 cannot contact the electromagnetic drying roller 42, the piston 83 is driven to move up and down inside the compensation cylinder 81 by the telescopic rod 82. Thus, the piston 83 pushes the boron carbide slurry upward, so that when the liquid level of the boron carbide slurry in the material box 6 drops after being dried partially and cannot contact the electromagnetic drying roller 42, the boron carbide slurry can be compensated.
