Description

Technical Field

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

[0002] Silicon carbide is an inorganic substance with the chemical formula SiC. It 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. It is a non-oxide high-tech refractory raw material such as C, N, and B.

[0003] In this regard, China has applied for patent number: CN218156460U, which discloses a raw material proportioning weighing device for silicon carbide blank production, including a weighing instrument, two trays are movably arranged on the upper end of the weighing instrument, fixed columns are fixedly installed on both sides of the upper end of the weighing instrument, and circular grooves are provided at the separated ends of the two fixed columns, and a material unloading mechanism is provided on both sides of the upper end of the weighing instrument, and the material unloading mechanism includes a supporting leg, a rectangular slide groove is provided at the lower end of the supporting leg, and a circular hole is provided at the side end. The utility model provides a storage bin and a partition inside the storage bin, so that the proportioning weighing device can conveniently take out the raw materials for weighing when weighing the raw materials of silicon carbide, and does not require the staff to use a container to take the raw materials of silicon carbide, and only needs to pull the pull rod to pull the baffle upwards, and then unload the materials, which is very convenient to operate.

[0004] However, in actual use, as the pull rod is pulled, the baffle will move upward, and the raw materials will drop. When the pull rod is released, the raw materials will be stuck on the outer surface of the baffle, causing the baffle to be unable to close the storage bin normally. Therefore, the material unloading effect is poor. At the same time, the raw materials cannot be transported quickly after weighing. Therefore, it has become an urgent problem to be solved to perfect and improve the above-mentioned problems. Summary of the invention

[0005] The purpose of the utility model is to provide a raw material proportioning and weighing device for silicon carbide production, so as to solve the problem proposed in the above-mentioned background technology that when the pull rod is pulled, the baffle will move upward, and the raw material will drop at this time. When the pull rod is released, the raw material will be stuck on the outer surface of the baffle, resulting in the baffle being unable to close the storage bin normally, so the material unloading effect is poor, and the raw material cannot be quickly transported after being weighed.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a raw material proportioning weighing device for silicon carbide production, comprising a weighing platform, a side block is fixedly connected to the back of the weighing platform, a material storage barrel is arranged on the front surface of the side block, a connecting plate is arranged on the inner side wall of the material storage barrel, a threaded ring is fixedly connected to the left side surface of the connecting plate, and a threaded rod is connected to the inner thread of the threaded ring;

[0009] Preferably, a tray is fixedly connected to the top surface of the block, and a bottom plate is provided on the inner bottom wall of the tray.

[0010] Preferably, a rotating shaft is provided on the front surface of the tray, and a sealing plate is provided on the outer surface of the rotating shaft.

[0011] Preferably, a connecting frame is fixedly connected to the lower surface of the tray, a mounting tube is sleeved and installed on the outer surface of the connecting frame, and a telescopic rod is provided on the lower surface of the mounting tube.

[0012] Preferably, a sliding groove is provided on the top surface of the weighing platform, a sliding block is provided inside the sliding groove, and a storage frame is provided on the top surface of the sliding block.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The raw material proportioning and weighing device for silicon carbide production is provided with side blocks, material storage barrels, connecting plates, threaded rings, threaded rods, arc frames, mounting rings, sealing rings and trays. When in use, the raw materials are first put into the material storage barrel, and then the threaded rod is rotated inside the threaded ring so that the threaded rod can be lowered inside the threaded ring, so that the threaded rod can drive the arc frame and the mounting ring to descend as a whole, and at this time the mounting ring can descend from the hole at the bottom of the material storage barrel, and at this time the raw materials start to descend, so that the raw materials will fall onto the surface of the tray, and then after the operation is completed, the threaded rod is continuously rotated, and at this time the threaded rod and the arc frame can rise, and since the arc frame is designed as an arc, and the mounting ring is adapted to the hole at the bottom of the material storage barrel, the raw materials at the edge can be driven to rise when the arc frame and the mounting ring rise, so as to prevent the raw materials from being stuck on the outer surface of the arc frame, and at the same time the sealing ring can seal the hole at the bottom of the material storage barrel as a whole, which reflects the practicality of the design.

[0015] The raw material proportioning weighing device for silicon carbide production is provided with a clamping block, a rotating column, a bottom plate, a rotating shaft, a sealing plate, a connecting frame, a mounting tube, a telescopic rod, a sliding groove and a sliding block. When in use, the raw material falls onto the surface of the pallet through the material storage tube, and then the raw material on the surface of the pallet is weighed by the weighing platform. After the weighing is completed, the sealing plate is rotated to open the front opening of the pallet, and then the telescopic rod is started to drive the mounting tube and the connecting frame to rise. At this time, the pallet will also rotate. The design of the clamping block and the rotating column allows the pallet to rotate. Before the pallet rotates, the storage frame is pushed to the front surface of the pallet, and the sliding block can slide inside the sliding groove. Then, the rotated pallet will dump the raw material onto the top surface of the storage frame, thereby completing the transportation of the raw material. Then, various raw materials are weighed in a cycle and then uniformly transported to the inside of the storage frame, so that the proportioning weighing operation can be performed, which reflects the functionality of the design.

The raw materials fall onto the surface of the tray 10 through the material storage barrel 3, and then the raw materials on the surface of the tray 10 are weighed by the weighing platform 1. After the weighing is completed, the sealing plate 15 is rotated to open the front opening of the tray 10, and then the telescopic rod 18 is started, and the mounting barrel 17 and the connecting frame 16 are driven to rise by the telescopic rod 18. At this time, the tray 10 will also rotate. The tray 10 can rotate through the design of the block 11 and the rotating column 12. Before the tray 10 rotates, the storage frame 21 is pushed to the front surface of the tray 10, and the sliding block 20 can slide inside the sliding groove 19. Then the rotated tray 10 will dump the raw materials onto the top surface of the storage frame 21, thereby completing the transportation of the raw materials, and then the various raw materials are weighed cyclically and then uniformly transported to the inside of the storage frame 21, so that the proportioning weighing operation can be performed;

[0024] The arc frame 7 is installed on the lower surface of the threaded rod 6. The lower surface of the arc frame 7 is provided with a mounting ring 8. The inner bottom wall of the storage barrel 3 is provided with a hole with the same diameter as the mounting ring 8. The lower surface of the mounting ring 8 is fixedly connected with a sealing ring 9. The mounting ring 8 and the hole are adapted to each other. First, the raw material is put into the inside of the storage barrel 3, and then the threaded rod 6 is rotated inside the threaded ring 5, so that the threaded rod 6 can be lowered inside the threaded ring 5, so that the threaded rod 6 will drive the arc frame 7 and the mounting ring 8 to descend as a whole. At this time The mounting ring 8 will drop from the hole at the bottom of the storage barrel 3, and the raw material will start to drop, so that the raw material will fall onto the surface of the tray 10. After the operation is completed, the threaded rod 6 will continue to be rotated, and the threaded rod 6 and the arc frame 7 will rise. Since the arc frame 7 is designed to be arc-shaped, and the mounting ring 8 and the hole at the bottom of the storage barrel 3 are adapted to each other, the raw material at the edge will be driven up when the arc frame 7 and the mounting ring 8 rise, thereby preventing the raw material from being stuck on the outer surface of the arc frame 7. At the same time, the sealing ring 9 can also seal the hole at the bottom of the storage barrel 3 as a whole.

[0025] Working principle: When the staff uses this device, first connect the device to an external power supply to provide power support for the device, first put the raw material into the storage barrel 3, and then rotate the threaded rod 6 inside the threaded ring 5 so that the threaded rod 6 can be lowered inside the threaded ring 5, so that the threaded rod 6 will drive the arc frame 7 and the mounting ring 8 to descend as a whole, and at this time the mounting ring 8 will descend from the hole at the bottom of the storage barrel 3. At this time, the raw material begins to descend, so that the raw material will fall onto the surface of the tray 10, and then after the operation is completed, continue to rotate the threaded rod 6, at this time the threaded rod 6 and the arc frame 7 will rise, because the arc frame 7 is an arc-shaped design, and the mounting ring 8 is adapted to the hole at the bottom of the storage barrel 3, so that when the arc frame 7 and the mounting ring 8 rise, the raw material on the edge will be driven up, thereby preventing the raw material from being stuck on the outside of the arc frame 7 The raw materials fall onto the surface of the tray 10 through the material storage barrel 3, and then the raw materials on the surface of the tray 10 are weighed by the weighing platform 1. After the weighing is completed, the sealing plate 15 is rotated to open the front opening of the tray 10, and then the telescopic rod 18 is started. The mounting barrel 17 and the connecting frame 16 are driven to rise by the telescopic rod 18. At this time, the tray 10 will also rotate. The tray 10 can be rotated by the design of the block 11 and the rotating column 12. Before the tray 10 rotates, the storage frame 21 is pushed to the front surface of the tray 10, and the sliding block 20 can slide inside the sliding groove 19. Then the rotated tray 10 will pour the raw materials onto the top surface of the storage frame 21, thereby completing the transportation of the raw materials, and then the various raw materials are weighed in a cycle and then uniformly transported to the inside of the storage frame 21. The above is all the working principles of the present utility model.

[0026] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form.
