Description

Technical Field

[0001] The utility model relates to the technical field of silicon carbide production, in particular to a subdivision screening device for silicon carbide production. Background Art

[0002] Diamond grit, also known as silicon carbide, 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 also a rare mineral in nature, moissanite. Silicon carbide is also called carbon silicon stone. Among contemporary non-oxide high-tech refractory raw materials such as C, N, B, silicon carbide is the most widely used and most economical one. It can be called diamond grit or refractory sand. In the production process of silicon carbide sleeves, for the quality of the sleeves, it is necessary to use a screening device to screen the silicon carbide to select silicon carbide of a certain size.

[0003] Prior art, such as publication number CN214235001U, provides a silicon carbide subdivision screening device for silicon carbide sleeve production, including a workbench, a plurality of pillars are fixedly connected to the lower side of the workbench, a box is provided on the upper side of the workbench, a filter is fixedly connected to the interior of the box, a support plate is fixedly connected to the upper side of the workbench, a push rod is fixedly connected to the inner top of the support plate, the lower end of the push rod extends to the interior of the box, and a vibration mechanism for vibrating the box is provided on the upper side of the workbench. The utility model has a reasonable structural design, can cause the filter to undergo large deformation and vibration, effectively prevent silicon carbide from being blocked in the mesh of the filter, and ensure the quality of screening. Secondly, the structure is simple, and there is no need to use multiple vibration motors, saving costs.

[0004] In this scheme, a top rod is set. When the box moves upward, the filter also moves upward. Since the filter can undergo reversible deformation, the top rod contacts and squeezes the filter, causing the filter to deform. Conversely, when the box moves downward, the filter is reset, thereby effectively preventing silicon carbide from being blocked in the mesh of the filter, ensuring the quality of screening. However, in reality, the filter requires a relatively high frequency of reciprocating motion, which causes the top rod to repeatedly squeeze the filter. This can easily cause wear of the filter over a long period of time, causing changes in the gaps in the filter, and affecting the filtering effect. In view of this, we propose a subdivision screening device for silicon carbide production. Utility Model Content

[0005] The utility model aims to provide a subdivision screening device for silicon carbide production, which solves the problem of reduced filtering effect due to wear of the filter screen.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A subdivision and screening device for silicon carbide production comprises a box body, a screening mechanism is arranged inside the box body, the screening mechanism comprises a rotating rod, the rotating rod is arranged inside the box body, and the two ends of the rotating rod respectively penetrate the box wall of the box body and are rotatably connected, the outer wall of the rotating rod is provided with a roller, and the cylinder wall of the roller is provided with a filtering hole, and the right side of the box body is provided with a driving mechanism for driving the rotating rod to rotate, and the roller arranged outside the rotating rod is driven to rotate by the driving mechanism, and the internal material is continuously rolled by the rotation of the roller, so as to facilitate the screening of the material through the filtering hole, and because the roller is in a rotating state, whenever the filtering hole rotates to the highest point in the roller, it is in an inverted state, so that the material on the inner wall of the filtering hole is not easy to adhere to, so as to reduce the possibility of clogging.

[0008] Preferably, the inner wall of the roller is connected to a slide cylinder, and slide bars are respectively connected to both sides of the rotating rod, and the slide bars are slidably connected to the inner wall of the slide cylinder. By arranging the slide cylinder to be slidably connected to the outer wall of the slide bar, the roller can slide left and right.

[0009] Preferably, the driving mechanism includes a driven gear, which is connected to one end of the right side of the rotating rod, and a driving gear is meshedly connected below the driven gear. A motor is connected to the right side of the box through a mounting plate, and the output end shaft of the motor is connected to the driving gear. The driving gear is driven to rotate by starting the motor, and the rotating rod is driven to rotate through the meshed driven gear.

[0010] Preferably, the inner wall of the roller is connected with a lifting plate, and the drum wall of the roller is connected with a drum door. The lifting plate can lift the material while the roller rotates to avoid the material from accumulating at the bottom of the inner wall of the roller, and can improve the efficiency of material tumbling to enhance the screening effect.

[0011] Preferably, a rocking block is connected to the left side of the roller, and a push block is arranged under the rotating rod. The push block is connected to the back side of the inner wall of the box body through a support plate, and the rotation path of the rocking block is in contact with the push block. When the roller rotates, the push block is driven to rotate. Since the rotation path of the rocking block is in contact with the push block, when the push block is in contact with the rocking block, since the roller is slidably connected to the slide bar through the slide cylinder, the roller slides to the right at this time.

[0012] Preferably, a spring is connected to the right side of the roller, and a support plate is sleeved on the outer wall of the rotating rod. One side of the support plate is connected to the spring. When the roller slides to the right, it will squeeze the spring on the left side. The tension of the spring will push the roller to move to the left, causing the roller to shake back and forth left and right, so as to facilitate shaking out the material blocking the filter hole through the vibration generated by the shaking, so as to avoid clogging the filter hole and affecting the screening efficiency.

[0013] Preferably, a box cover is hinged on the top of the box body, a through slot is provided on the front of the box body, a drawer box is slidably connected to the inner wall of the through slot, a handle is connected to the front of the drawer box, and the drawer box is used to collect screened materials.

[0014] By means of the above technical solution, the utility model provides a subdivision screening device for silicon carbide production, which has at least the following beneficial effects:

[0015] 1. The utility model drives the roller arranged outside the rotating rod to rotate through the driving mechanism, and the internal materials are continuously rolled by the rotation of the roller, so as to facilitate repeated screening of the materials through the filter holes. Moreover, since the roller is in a rotating state, whenever the filter hole rotates to the highest point in the roller, it is in an inverted state, so that the materials on the inner wall of the filter hole are not easy to adhere, so as to reduce the possibility of clogging.

[0016] 2. When the roller of the utility model rotates, it will drive the push block to rotate. Since the rotation path of the rocking block contacts the push block, when the push block contacts the rocking block, the roller is connected to the slide bar through the sliding cylinder, so that the roller slides to the right at this time. When the roller slides to the right, it will squeeze the spring on the left. The tension of the spring will push the roller to the left, causing the roller to shake back and forth left and right, so as to facilitate the shaking out of the material blocking the filter hole through the vibration generated by the shaking, so as to avoid the filter hole being blocked and affecting the screening efficiency.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] A subdivision screening device for silicon carbide production, such as Figure 1 - Figure 4 As shown, it includes a box body 1, and a screening mechanism 2 is arranged inside the box body 1. The screening mechanism 2 includes a rotating rod 21, the rotating rod 21 is arranged inside the box body 1, and the two ends of the rotating rod 21 respectively penetrate the box wall of the box body 1 and are rotatably connected, the outer wall of the rotating rod 21 is provided with a roller 22, and the cylinder wall of the roller 22 is provided with a filtering hole 221, and a driving mechanism 3 for driving the rotating rod 21 to rotate is arranged on the right side of the box body 1, and the roller 22 arranged outside the rotating rod 21 is driven to rotate by the driving mechanism 3. The rotation of the roller 22 causes the internal material to roll continuously, so as to facilitate the screening of the material through the filtering hole 221, and because the roller 22 is in a rotating state, whenever the filtering hole 221 rotates to the highest point in the roller 22, it is in an inverted state, so that the material on the inner wall of the filtering hole 221 is not easy to adhere to, so as to reduce the possibility of clogging, and the inner wall of the roller 22 is connected with a slide cylinder 220, and the two sides of the rotating rod 21 are respectively connected The roller 22 can slide left and right by being provided with a sliding bar 211, and the sliding bar 211 is slidably connected to the inner wall of the sliding drum 220. The sliding drum 220 is slidably connected to the outer wall of the sliding bar 211, so that the roller 22 can slide left and right. The driving mechanism 3 includes a driven gear 31, and the driven gear 31 is connected to one end of the right side of the rotating rod 21. The driven gear 31 is meshed and connected with a driving gear 32 below. The right side of the box body 1 is connected to a motor 33 through a mounting plate 34, and the output end shaft of the motor 33 is connected to the driving gear 32. The driving gear 32 is driven to rotate by starting the motor 33, and the rotating rod 21 is driven to rotate by the meshing driven gear 31. The inner wall of the roller 22 is connected with a lifting plate 222, and the cylinder wall of the roller 22 is connected with a cylinder door 223. When the roller 22 rotates, the lifting plate 222 is provided to lift the material to avoid the material from being concentrated and accumulated at the bottom of the inner wall of the roller 22, and the efficiency of material tumbling can be improved to improve the screening effect.

[0026] In this embodiment, the driving gear 32 is driven to rotate by starting the motor 33, and the meshing driven gear 31 drives the roller 22 set outside the rotating rod 21 to rotate. The rotation of the roller 22 causes the internal material to roll continuously, so as to facilitate the screening of the material through the filter hole 221. Since the roller 22 is in a rotating state, whenever the filter hole 221 rotates to the highest point in the roller 22, it is in an inverted state, so that the material on the inner wall of the filter hole 221 is not easy to adhere, so as to reduce the possibility of blockage. While the roller 22 is rotating, the material can be lifted by setting the lifting plate 222 to avoid the material from being concentrated and accumulated at the bottom of the inner wall of the roller 22, and the efficiency of material rolling can be improved to improve the screening effect.

[0027] Example 2

[0028] like Figure 2 As shown, a rocking block 232 is connected to the left side of the roller 22, and a push block 231 is arranged below the rotating rod 21. The push block 231 is connected to the back side of the inner wall of the box body 1 through the support plate 23, and the rotating path of the rocking block 232 contacts the push block 231. When the roller 22 rotates, the push block 231 is driven to rotate. Since the rotating path of the rocking block 232 contacts the push block 231, when the push block 231 contacts the rocking block 232, the roller 22 is slidably connected to the slide bar 211 through the slide 220, so that the roller 22 slides to the right at this time. A spring 234 is connected to the right side of the roller 22, and the outer wall of the rotating rod 21 is provided with a sleeve A support plate 233, one side of the support plate 233 is connected to a spring 234. When the roller 22 slides to the right, the spring 234 on the left side is squeezed. The tension of the spring 234 pushes the roller 22 to move to the left, causing the roller 22 to shake back and forth left and right, so as to facilitate shaking out the material blocking the filter hole 221 through the vibration generated by the shaking, so as to avoid the filter hole 221 being blocked and affecting the screening efficiency. A box cover 11 is hinged on the top of the box body 1, and a through groove 12 is provided on the front of the box body 1. A draw box 13 is slidably connected to the inner wall of the through groove 12, and a handle 131 is connected to the front of the draw box 13. The draw box 13 is used to collect the screened materials.

[0029] In this embodiment, when the roller 22 rotates, it will drive the push block 231 to rotate. Since the rotation path of the rocking block 232 is in contact with the push block 231, when the push block 231 is in contact with the rocking block 232, the roller 22 is slidably connected to the slide bar 211 through the slide 220, so that the roller 22 slides to the right at this time. When the roller 22 slides to the right, it will squeeze the spring 234 on the left. The tension of the spring 234 will push the roller 22 to move to the left, causing the roller 22 to shake back and forth left and right, so as to facilitate the vibration generated by the shaking to shake out the material blocking the filter hole 221, so as to avoid the filter hole 221 being blocked and affecting the screening efficiency.

[0030] When the utility model is used, a subdividing screening device for silicon carbide production drives the driving gear 32 to rotate by starting the motor 33, and drives the roller 22 arranged outside the rotating rod 21 to rotate by the meshing driven gear 31. The internal materials are continuously rolled by the rotation of the roller 22, so that the materials can be screened through the filter hole 221 conveniently. Since the roller 22 is in a rotating state, whenever the filter hole 221 rotates to the highest point in the roller 22, it is in an inverted state, so that the materials on the inner wall of the filter hole 221 are not easy to adhere to, so as to reduce the possibility of clogging. When the roller 22 rotates, the materials can be lifted up by setting the lifting plate 222, so as to avoid the materials from being concentrated and accumulated on the roller 221. The bottom of the inner wall of the roller 22 can improve the efficiency of material tumbling to improve the screening effect. When the roller 22 rotates, it will drive the push block 231 to rotate. Since the rotation path of the shaking block 232 contacts the push block 231, when the push block 231 contacts the shaking block 232, the roller 22 is slidably connected to the slide bar 211 through the slide 220, so that the roller 22 slides to the right at this time. When the roller 22 slides to the right, it will squeeze the spring 234 on the left. The tension of the spring 234 will push the roller 22 to move to the left, so that the roller 22 will shake back and forth left and right, so as to facilitate the vibration generated by the shaking to shake out the material blocking the filter hole 221, so as to avoid the filter hole 221 being blocked and affecting the screening efficiency.
