Description

Technical Field

[0001] The present invention relates to the technical field of material preparation, and particularly to a silicon carbide smelting furnace. Background Art

[0002] A silicon carbide smelting furnace is a professional device for producing silicon carbide. Its main function is to convert silicon-based raw materials and carbon-based raw materials into silicon carbide through high-temperature chemical reactions. Mixing quartz sand and petroleum coke in a certain proportion and adding them to the smelting furnace is to utilize the high-temperature environment provided by the smelting furnace to cause a chemical reaction between the two, thereby generating this important industrial material, silicon carbide, to meet the application requirements of silicon carbide in many industries such as abrasives, refractory materials, and semiconductors. During feeding, it is necessary for workers to first add the pre-prepared proportion into the furnace. During the smelting process, according to the actual reaction situation in the furnace, sometimes it is necessary to fine-tune the raw material proportion. It is very difficult for manual feeding to make corresponding adjustments in a timely and accurate manner during the feeding process. When it is found that the reaction in the furnace is abnormal due to the raw material ratio problem, it is impossible to quickly and accurately change the proportion of subsequent feeding to correct it, which may cause damage to the quality of the entire furnace of products.

[0032] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that exclude each other from other embodiments.

[0033] Embodiment 1

[0034] Referring to Figures 2 to 10 , this is the first embodiment of the present invention. This embodiment provides a silicon carbide smelting furnace, which includes a blanking assembly 200, a clutch assembly 300 and a main body assembly 100. The cooperation of the three can make the proportion of the raw materials subsequently added into the furnace closer to the ideal state.

[0035] The blanking assembly 200 includes a blanking member 201, which includes a blanking pipe 201a, a screw rod 201b, a blanking frame 201c, a rotating frame 201d, a first extrusion bar 201e, a second extrusion bar 201k, a driving disc 201f, an extrusion plate 201g, and a rotating bar 201h. The screw rod 201b is located inside the blanking pipe 201a, and the screw rod 201b and the blanking pipe 201a are rotatably connected by a rotating shaft. The blanking frame 201c is fixed to the top of the blanking pipe 201a, the rotating frame 201d is fixed to one end of the screw rod 201b, the first extrusion bar 201e is arranged on one side of the rotating frame 201d, the second extrusion bar 201 is arranged on the driving disc 201f, the second extrusion bar 201k is arranged on one side of the first extrusion bar 201e, the driving disc 201f is fixed to one side of the first extrusion bar 201e, the driving disc 201f is sleeved outside the second extrusion bar 201k, and the driving disc 201f and the second extrusion bar 201k are movably connected. The extrusion plate 201g is fixed to one side of the second extrusion bar 201k, and the rotating bar 201h is arranged on one side of the extrusion plate 201g. The rotating bar 201h is rotatably connected to the inside of the driving disc 201f through a rotating shaft.

[0036] Two sets of blanking assemblies 200 are provided, both of which are arranged on the top of the smelting furnace body 101. By pouring the raw materials to be added into the blanking pipe 201a from the blanking frame 201c respectively, and then the rotation of the screw rod 201b can push the raw materials, so that the raw materials are transported into the smelting furnace body 101 for processing. A driving groove corresponding to the first extrusion bar 201e and the second extrusion bar 201k is provided on one side of the rotating frame 201d. When the driving disc 201f rotates, it can drive the first extrusion bar 201e to move. When the first extrusion bar 201e moves into the driving groove and extrudes it, it can drive the rotating frame 201d to rotate. By the rotation of the rotating frame 201d, the screw rod 201b can be driven to rotate. The number of the second extrusion bars 201k is two, both of which are arranged on the driving disc 201f. By rotating the rotating bar 201h, the second extrusion bar 201k can be extruded to extend out of the driving disc 201f. At this time, the number of times of engaging with the driving groove can be increased, so that the rotation speed of the screw rod 201b can be adjusted, and then the blanking speed can be adjusted. The number of the rotating bars 201h is two, both of which are arranged inside the driving disc 201f. By rotating different numbers of rotating bars 201h, different numbers of second extrusion bars 201k can be extruded.

[0037] The clutch assembly 300 is disposed on the blanking member 201 and includes a first bevel gear 301a, a second bevel gear 301b, a first rotating rod 301c, a first driving strip 301d, a driving housing 301e, a second rotating rod 301f, and a second driving strip 301g. The first bevel gear 301a is disposed on one side of the driving disk 201f. The second bevel gear 301b is located on one side of the first bevel gear 301a. The second bevel gear 301b meshes with the first bevel gear 301a. The first rotating rod 301c is fixed to one side of the second bevel gear 301b. One end of the first driving strip 301d is fixed to one side of the first rotating rod 301c. The driving housing 301e is sleeved outside the first rotating rod 301c, and the driving housing 301e is movably connected to the first rotating rod 301c. The second rotating rod 301f is located inside the driving housing 301e, and the second rotating rod 301f is movably connected to the driving housing 301e. The second driving strip 301g is fixed to one side of the second rotating rod 301f.

[0038] The number of the first bevel gear 301a and the second bevel gear 301b is two, and both are disposed on one side of the driving disk 201f. A motor is fixed on one side of the first bevel gear 301a. By starting the motor, the first bevel gear 301a can be driven to rotate. The rotation of the first bevel gear 301a will drive the second bevel gear 301b to rotate. By the rotation of the second bevel gear 301b, the first rotating rod 301c can be driven to rotate. The rotation of the first rotating rod 301c can drive the first driving strip 301d to rotate. A card slot corresponding to the first driving strip 301d is formed on the driving housing 301e. By engaging the first driving strip 301d with the card slot, and then the rotation of the first driving strip 301d can drive the driving housing 301e to rotate. By the rotation of the driving housing 301e, the second driving strip 301g can be driven to rotate. At this time, the rotation of the second driving strip 301g can drive the second rotating rod 301f to rotate. By the rotation of the second rotating rod 301f, another second bevel gear 301b can be driven to rotate, and then another first bevel gear 301a can be driven to rotate. At this time, another screw rod 201b can be driven to rotate, so as to perform blanking. When only one kind of raw material needs to be blanked, by moving the driving housing 301e, at this time, the driving housing 301e can drive the card slot to be separated from the first driving strip 301d. When the first driving strip 301d rotates, it will not drive the driving housing 301e to rotate, so that one screw rod 201b can rotate to blank only one kind of raw material.

[0039] Embodiment 2

[0040] Refer to Figures 2 to 10 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0041] Specifically, the blanking assembly 200 further includes a rotating member 202 disposed on the rotating bar 201h. One side of the rotating bar 201h is inserted with a plug rod 202a. One side of the plug rod 202a is fixed with a clamping block 202b. One end of the plug rod 202a is inserted into the inner wall of the driving disk 201f. The plug rod 202a is movably connected to the driving disk 201f. One end of the plug rod 202a is fixed with a first spring 202c, and the first spring 202c is fixed to the inner wall of the driving disk 201f. One side of the driving disk 201f is provided with a positioning plate 202d. The driving disk 201f and the positioning plate 202d are rotatably connected through a bearing. The first bevel gear 301a is inserted into one side of the plug rod 202a, and the first bevel gear 301a is movably connected to the plug rod 202a.

[0042] Connection grooves corresponding to the clamping blocks 202b are formed on both rotating bars 201h. By moving the plug rod 202a, the clamping block 202b can be driven to move. The clamping block 202b will slide in the connection groove. By engaging the clamping block 202b with the clamping grooves on the two rotating bars 201h respectively, and then rotating the plug rod 202a, the two rotating bars 201h can be driven to rotate simultaneously to squeeze the pressing plate 201g, driving the second pressing bar 201k to extend out of the driving disk 201f. When squeezing the plug rod 202a, a squeezing force can be applied to the first spring 202c. When the plug rod 202a is released, the first spring 202c rebounds to drive the plug rod 202a to return to its original position, and then the clamping block 202b will engage with the clamping groove on one of the rotating bars 201h. When the plug rod 202a is rotated again, one rotating bar 201h can be driven to rotate, so that one second pressing bar 201k can be extended out of the driving disk 201f.

[0043] Specifically, a locking disk 202e is sleeved on the outer side of the plug rod 202a. One side of the locking disk 202e is provided with an inclined plane frame 202f. One side of the inclined plane frame 202f is fixed with a moving bar 202g. The moving bar 202g is inserted into one side of the driving disk 201f. The moving bar 202g is movably connected to the driving disk 201f.

[0044] When pressing the plug rod 202a, in order to prevent the first spring 202c from rebounding to drive the plug rod 202a to return to its original position, the locking disk 202e is moved to squeeze the inclined plane frame 202f. At this time, the inclined plane frame 202f will move. Then the locking disk 202e is continuously moved so that the locking disk 202e moves to one side of the inclined plane frame 202f. Then, through the setting of the inclined plane frame 202f, the locking disk 202e can be limited. When it is necessary to release the limit on the locking disk 202e, the inclined plane frame 202f is driven to separate from the locking disk 202e by moving the moving bar 202g, so that the limit on the locking disk 202e can be released.

[0045] Specifically, a support cover 202h is sleeved outside the moving bar 202g. The moving bar 202g and the support cover 202h are movably connected. The support cover 202h is fixed to the inner wall of the driving disk 201f. One end of the moving bar 202g is fixed with a second spring 202i, and the second spring 202i is fixed to the inner wall of the support cover 202h.

[0046] The arrangement of the support cover 202h can support the moving bar 202g to prevent the moving bar 202g from shifting. When moving the moving bar 202g, an extrusion force can be applied to the second spring 202i. When the moving bar 202g is released, the moving bar 202g can be driven back to its original position by the rebounding force of the second spring 202i.

[0047] Specifically, a moving disk 202j is sleeved outside the insertion rod 202a. A limiting block 202k is arranged inside the moving disk 202j. One side of the limiting block 202k is fixed with a movable plate 202l. One side of the movable plate 202l is fixed with a third spring 202m, and the third spring 202m is fixed to the inner wall of the moving disk 202j.

[0048] First, move the limiting block 202k so that it moves into the moving disk 202j. When the limiting block 202k moves, it can drive the movable plate 202l to move. By the movement of the movable plate 202l, an extrusion force can be applied to the third spring 202m. A limiting groove corresponding to the limiting block 202k is formed in the driving disk 201f. When rotating the insertion rod 202a, the moving disk 202j can be driven to rotate. The rotation of the moving disk 202j can drive the limiting block 202k to rotate. After moving and rotating the moving disk 202j to a specified position, by releasing the limiting block 202k, the rebounding force of the third spring 202m will drive the limiting block 202k back to its original position. At this time, the limiting block 202k can be re-engaged with the limiting groove, thereby limiting the insertion rod 202a to prevent the insertion rod 202a from moving by itself.

[0049] Specifically, one side of the rotating bar 201h is fixed with a fourth spring 202n. One end of the fourth spring 202n is fixed with a fixing block 202o, and the fixing block 202o is fixed to the inner wall of the driving disk 201f. One side of the pressing plate 201g is fixed with a fifth spring 202p, and the fifth spring 202p is fixed to the inner wall of the driving disk 201f.

[0050] When the rotating bar 201h rotates, a squeezing force can be applied to the fourth spring 202n, and when the pressing plate 201g is squeezed, a squeezing force can be applied to the fifth spring 202p. When the limit on the insertion rod 202a is released, the elastic force of the fourth spring 202n drives the rotating bar 201h to separate from the pressing plate 201g and relieve the squeezing on it. Then, the elastic force of the fifth spring 202p can drive the second pressing bar 201k to return to its original position. The setting of the fixing block 202o can support the fourth spring 202n and prevent the fourth spring 202n from shifting.

[0051] Embodiment 3

[0052] Refer to Figures 1 to 10 , which is the third embodiment of the present invention, and this embodiment is based on the first two embodiments.

[0053] Specifically, the clutch assembly 300 further includes a support member 302 disposed on the drive housing 301e. A sixth spring 302a is fixed to one side of the drive housing 301e. One end of the second rotating rod 301f is fixed with a connecting column 302b. A fixing frame 302c is sleeved outside the connecting column 302b. The fixing frame 302c is movably connected to the connecting column 302b. A retaining disc 302d is sleeved outside the connecting column 302b. The sixth spring 302a is fixed to one side of the retaining disc 302d.

[0054] When the drive housing 301e is moved, a squeezing force can be applied to the sixth spring 302a. The elastic force of the sixth spring 302a can drive the drive housing 301e to return to its original position. When the second rotating rod 301f rotates, it can drive the connecting column 302b to rotate. By the rotation of the connecting column 302b, another second bevel gear 301b can be driven to rotate. The fixing frame 302c is fixed to the top of the smelting furnace body 101. The setting of the fixing frame 302c can support the connecting column 302b. The retaining disc 302d is used to support the sixth spring 302a.

[0055] Specifically, a first connecting plate 302e is disposed on one side of the first bevel gear 301a. The first connecting plate 302e and the first bevel gear 301a are rotatably connected by a rotating shaft. A second connecting plate 302f is sleeved outside the second bevel gear 301b. The second bevel gear 301b and the second connecting plate 302f are rotatably connected by a rotating shaft.

[0056] The first connecting plate 302e is fixed to the top of the smelting furnace body 101. The setting of the first connecting plate 302e can support the first bevel gear 301a. A motor is fixed to one side of the first connecting plate 302e and on one side of the first bevel gear 301a. The second connecting plate 302f is fixed to the top of the smelting furnace body 101. The setting of the second connecting plate 302f can support the second bevel gear 301b.

[0057] Specifically, a moving sleeve 302k is sleeved outside the driving housing 301e. The moving sleeve 302k and the driving housing 301e are rotatably connected through a rotating shaft. A moving frame 302g is fixed at the top of the moving sleeve 302k. The moving frame 302g is movably connected to the top of the fixed frame 302c. An inclined surface block 302h is fixed on one side of the moving frame 302g, and a limiting frame 302i is fixed on one side of the fixed frame 302c.

[0058] Moving the moving frame 302g can drive the moving sleeve 302k to move. At this time, the driving housing 301e can be driven to move. When the driving housing 301e moves, in order to prevent the driving housing 301e from returning to its original position due to the rebounding force of the sixth spring 302a, the driving housing 301e can be limited by moving the inclined surface block 302h to engage with the limiting frame 302i. The inclined surface block 302h itself has a certain elasticity. By pressing the inclined surface block 302h to separate it from the limiting frame 302i, the driving housing 301e can be driven to return to its original position by the rebounding force of the sixth spring 302a.

[0059] Specifically, it further includes a main body assembly 100, which is arranged on the blanking pipe 201a and includes a smelting furnace body 101 and support legs 102. The smelting furnace body 101 is fixed at the bottom of the blanking pipe 201a, and the support legs 102 are fixed to the bottom of the smelting furnace body 101.

[0060] The smelting furnace body 101 converts the silicon-based raw material and the carbon-based raw material into silicon carbide through a high-temperature chemical reaction. The quartz sand and petroleum coke are mixed in a certain proportion and then added to the smelting furnace body 101. By utilizing the high-temperature environment provided by the smelting furnace body 101, the two undergo a chemical reaction to generate silicon carbide, an important industrial material, to meet the application requirements of silicon carbide in many industries such as abrasives, refractory materials, and semiconductors. The support legs 102 can support the smelting furnace body 101 to prevent the smelting furnace body 101 from shifting.

[0061] In use, first, the raw materials such as quartz sand and petroleum coke that are mixed in proportion are respectively poured into the blanking pipe 201a from the blanking frames 201c of the two groups of blanking components 200. Then, start the motor fixed on the first connecting plate 302e and connected to the first bevel gear 301a. The motor drives the first bevel gear 301a to rotate. The first bevel gear 301a drives the second bevel gear 301b meshing with it to rotate. The second bevel gear 301b drives the first rotating rod 301c to rotate. The first rotating rod 301c drives the first driving strip 301d to rotate. If the first driving strip 301d is engaged with the card slot on the driving shell 301e, the rotation of the first driving strip 301d drives the driving shell 301e to rotate. The rotation of the driving shell 301e drives the second driving strip 301g to rotate. The rotation of the second driving strip 301g drives the second rotating rod 301f to rotate. The rotation of the second rotating rod 301f drives the connecting column 302b to rotate. The rotation of the connecting column 302b drives another second bevel gear 301b to rotate. Another second bevel gear 301b drives another first bevel gear 301a to rotate, thereby driving the two screw rods 201b to rotate, and pushing the raw materials to be transported into the smelting furnace body 101 for processing. If it is necessary to adjust the blanking speed, operate the rotating part 202, move the inserting rod 202a. The inserting rod 202a drives the clamping block 202b to move. The clamping block 202b slides in the connecting slot of the rotating strip 201h, and engages the clamping block 202b with the card slots on the two rotating strips 201h respectively. Rotating the inserting rod 202a can drive the two rotating strips 201h to rotate simultaneously. The rotation of the rotating strip 201h squeezes the extrusion plate 201g, so that the second extrusion strip 201k extends out of the driving disc 201f, increasing the number of engagements with the driving slot on the rotating frame 201d, and improving the rotation speed of the screw rod 201b and the blanking speed; loosen the inserting rod 202a, and the first spring 202c rebounds to make the inserting rod 202a return to its original position. The clamping block 202b is engaged with the card slot on one of the rotating strips 201h. Rotating the inserting rod 202a again only drives one rotating strip 201h to rotate, so that one second extrusion strip 201k extends out of the driving disc 201f. When pressing the inserting rod 202a, move the locking disc 202e to squeeze the inclined plane frame 202f. The inclined plane frame 202f moves. Continue to move the locking disc 202e to one side of the inclined plane frame 202f. The inclined plane frame 202f limits the locking disc 202e to prevent the first spring 202c from rebounding to make the inserting rod 202a reset;When the limit needs to be released, moving the moving bar 202g drives the inclined plane frame 202f to separate from the locking disk 202e. A support cover 202h is sleeved outside the moving bar 202g to prevent deviation. Moving the moving bar 202g will compress the second spring 202i. After releasing, the second spring 202i rebounds to drive the moving bar 202g to reset. When rotating the insertion rod 202a, it drives the moving disk 202j to rotate. The moving disk 202j drives the limit block 202k to rotate. First, move the limit block 202k into the moving disk 202j. The movable plate 202l moves accordingly and compresses the third spring 202m. After moving and rotating the moving disk 202j to the specified position, release the limit block 202k. The third spring 202m rebounds to drive the limit block 202k to re-engage with the limit groove in the drive disk 201f, limiting the insertion rod 202a to prevent it from moving by itself. When the rotating bar 201h rotates, it will compress the fourth spring 202n. When the pressing plate 201g is pressed, it will compress the fifth spring 202p. When the limit on the insertion rod 202a is released, the fourth spring 202n rebounds to drive the rotating bar 201h to separate from the pressing plate 201g, releasing the pressure on the pressing plate 201g. Then the fifth spring 202p rebounds to drive the second pressing bar 201k back to its original position.;

[0062] When only one type of raw material needs to be fed, by moving the moving frame 302g, the moving frame 302g drives the moving sleeve 302k to move. The moving sleeve 302k drives the drive shell 301e to move, causing the card slot on the drive shell 301e to separate from the first drive bar 301d. At this time, the rotation of the first drive bar 301d will not drive the drive shell 301e to rotate. Only one screw rod 201b rotates, and only one type of raw material can be fed. When the drive shell 301e moves, it will compress the sixth spring 302a. If you want the drive shell 301e to return to its original position, you can press the inclined plane block 302h to separate it from the limit frame 302i. The sixth spring 302a rebounds to drive the drive shell 301e back to its initial position. At the same time, the first bevel gear 301a is supported by the first connecting plate 302e, the second bevel gear 301b is supported by the second connecting plate 302f, the connecting column 302b at one end of the second rotating rod 301f is supported by the fixed frame 302c, and the retaining disk 302d is used to support the sixth spring 302a, so as to ensure the normal operation of each component and enable the entire device to stably complete the raw material feeding and related adjustment operations according to requirements, so as to meet the different requirements for raw material addition in the smelting process.
