Description

Technical Field

[0001] This utility model relates to the field of silicon carbide dehydration technology, and in particular to a rapid dehydration and drying machine for silicon carbide production. Background Technology

[0002] Silicon carbide production rapid dehydration dryers typically use screw feeding or vibration equipment to feed silicon carbide into the dehydration dryer. However, the screw feeding channel is easily worn by silicon carbide particles, and the maintenance of the screw feeding channel is difficult. Vibration feeding cannot ensure the uniformity of feeding, and vibration equipment also has the potential to affect other components of the dehydration dryer, leading to increased maintenance costs. Both of these situations reduce the user comfort of general dehydration dryers. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a rapid dehydration and drying machine for silicon carbide production, which improves the convenience of centralized transportation of silicon carbide, increases the looseness of silicon carbide during the dehydration and drying process, and improves the efficiency of dehydration and drying.

[0004] This utility model also provides a rapid dehydration and drying machine for silicon carbide production, comprising: a drying chamber, a hot air blower and an exhaust mechanism fixedly connected to the surface of the drying chamber, a heating mechanism and a storage drawer arranged inside the drying chamber, the heating mechanism being located below the storage drawer, the storage drawer being slidably connected to the drying chamber, a long rod and a positioning tube arranged on the upper surface of the drying chamber, the positioning tube being rotatably connected to the upper surface of the drying chamber, the lower end of the long rod passing through the positioning tube and penetrating into the interior of the drying chamber, a combing disc fixedly connected to the lower end of the long rod, the lower end of the combing disc being in close contact with the lower inner wall of the storage drawer when the dehydration and drying machine is used, and multiple metal strips fixedly connected to the lower end of the combing disc, the inner walls of the metal strips being in contact.

[0005] According to the present invention, a rapid dehydration and drying machine for silicon carbide production includes an automatic telescopic rod fixedly connected to the upper surface of the drying chamber. The output end of the automatic telescopic rod is rotatably connected to the upper end of the long rod via a long plate. This improves the convenience of sliding the long rod up and down.

[0006] According to the present invention, a rapid dehydration and drying machine for silicon carbide production includes a servo motor fixedly connected to the upper surface of the drying chamber, and a gear set fixedly connected between the output end of the servo motor and the side surface of the positioning tube. This improves the ease of rotating the positioning tube.

[0007] According to the present invention, a rapid dehydration and drying machine for silicon carbide production includes two heating plates at the upper end of the combing disc, which are embedded in the upper surface of the combing disc. This improves the heating effect on the silicon carbide.

[0008] According to the present invention, a rapid dehydration and drying machine for silicon carbide production includes grooves and locking blocks on the side surface of the long rod and the inner wall of the positioning tube, respectively. The locking block is fixedly connected to the positioning tube, with its end furthest from the positioning tube located inside the groove. This increases the friction between the long rod and the positioning tube.

[0009] According to the present invention, a rapid dehydration and drying machine for silicon carbide production has a clamping block whose length and width are the same as the depth and width of the groove, and whose surface is in close contact with the inner wall of the groove. This reduces the risk of vertical slippage of the long plate.

[0010] According to the present invention, in a rapid dehydration and drying machine for silicon carbide production, the length of the metal strip is greater than the distance between the combing disc and the inner wall of the storage drawer. When using the dehydration and drying machine, the metal strip at any position is in contact with the inner wall of the storage drawer, thus improving the effectiveness of the metal strip.

[0011] Beneficial effects:

[0012] Compared with existing technologies, this rapid dehydration and drying machine for silicon carbide production uses a storage drawer, a long rod, a combing disc, metal strips, and positioning tubes to centrally store the silicon carbide to be dehydrated and dried. The rotating combing method improves the dispersion effect of silicon carbide during the dehydration and drying process, thereby increasing the dehydration and drying efficiency. The structure of the long rod driving the combing disc to slide up and down provides convenience for pulling out and pushing the storage drawer. Moreover, the simple structure of the above components reduces the maintenance cost and cleaning difficulty of the dehydration and drying machine. Attached Figure Description

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Reference Figure 1-4 This utility model provides a rapid dehydration and drying machine for silicon carbide production, comprising: a drying chamber 1, a hot air blower 2 and an exhaust mechanism 4 fixedly connected to the surface of the drying chamber 1, a heating mechanism 3 and a storage drawer 12 disposed inside the drying chamber 1, the heating mechanism 3 being located below the storage drawer 12, and the storage drawer 12 being slidably connected to the drying chamber 1. The above components cooperate with each other to form the basic structure of the dehydration and drying machine. The hot air blower 2, the exhaust mechanism 4, and the heating mechanism 3 are all commonly used devices in daily life, used to change the temperature of the drying chamber 1 and maintain the dryness of the drying chamber 1.

[0022] A long rod 6 and a positioning tube 7 are provided on the upper surface of the drying chamber 1. The positioning tube 7 is rotatably connected to the upper surface of the drying chamber 1. The lower end of the long rod 6 passes through the positioning tube 7 and extends into the interior of the drying chamber 1. A groove 11 and a locking block 10 are respectively provided on the side surface of the long rod 6 and the inner wall of the positioning tube 7. The locking block 10 is fixedly connected to the positioning tube 7, and the end away from the positioning tube 7 is located inside the groove 11. The length and width of the locking block 10 are the same as the depth and width of the groove 11, and the surface of the locking block 10 is in close contact with the inner wall of the groove 11. The locking block 10 and the groove 11 are in close contact. The positioning tube 7 and the long rod 6 are integrated to ensure that the positioning tube 7 can drive the long rod 6 to rotate. An automatic telescopic rod 9 is fixedly connected to the upper surface of the drying chamber 1. The output end of the automatic telescopic rod 9 is rotatably connected to the upper end of the long rod 6 through a long plate. The automatic telescopic rod 9 is used to provide power for the up and down sliding long rod 6. A servo motor 5 is fixedly connected to the upper surface of the drying chamber 1. A gear set 8 is fixedly connected between the output end of the servo motor 5 and the side surface of the positioning tube 7. The servo motor 5 and the gear set 8 cooperate to provide rotational power for the positioning tube 7.

[0023] A combing disc 13 is fixedly connected to the lower end of the long rod 6. When using the dehydration dryer, the lower end of the combing disc 13 is in close contact with the lower inner wall of the storage drawer 12. The combing disc 13 consists of a disc and multiple rods. The silicon carbide is dispersed by the collision between the rods and the silicon carbide. Multiple metal strips 14 are fixedly connected to the lower end of the combing disc 13. The inner wall of the metal strips 14 is in contact with the inner wall of the storage drawer 12. The length of the metal strips 14 is greater than the distance between the combing disc 13 and the inner wall of the storage drawer 12. When using the dehydration dryer, the metal strips 14 at any position are in close contact with the inner wall of the storage drawer 12. The inner wall of drawer 12 is in contact with the metal strip 14, which is used to expand the working range of the combing disc 13. The metal strip 14 itself bends when subjected to excessive pressure, so that the metal strip 14 can always be in contact with the inner wall of the drawer 12 during rotation. Both the metal strip 14 and the combing disc 13 are made of highly thermally conductive materials. Two heating plates 15 are provided at the upper end of the combing disc 13. The heating plates 15 are embedded in the upper surface of the combing disc 13. The heating plates 15 are used to increase the temperature of the combing disc 13 and the metal strip 14, thereby improving the contact effect between silicon carbide and heat.

[0024] Working principle: When adding silicon carbide, first change the height of the combing disc 13 to detach it from the drawer 12. Then, pull out the drawer 12 and pour the silicon carbide directly into the drawer 12. Note that at least one-third of the space in the drawer 12 should be reserved. After adding, push the drawer 12 into the drying chamber 1, and then lower the height of the combing disc 13 to enter the drawer 12. At this time, the heating mechanism 3 and the heating plate 15 can be turned on to increase the temperature inside the drying chamber 1. At the same time, the servo motor 5 is turned on to rotate the long rod 6 through the gear set 8 and the positioning tube 7. The round rod at the lower end of the combing disc 13 in the rotating state collides with the metal strip 14 to disperse the silicon carbide. During this process, the drawer 12 is heated and transfers heat to the silicon carbide. The combing disc 13 is directly heated by the heating plate 15, which further improves the heating effect of the silicon carbide.

[0025] In the process of dispersing silicon carbide using the combing disc 13, silicon carbide can be processed by layer combing. That is, first disperse the silicon carbide in the uppermost layer, and after a period of time, further reduce the height of the combing disc 13 to disperse the silicon carbide inside the storage drawer 12 in multiple stages.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
