Description

Technical Field

[0001] This utility model relates to the field of stirring equipment technology, and in particular to a stirring and dispersing device for silicon carbide micro powder. Background Technology

[0002] Silicon carbide micron powder refers to micron-sized silicon carbide powder produced through ultrafine grinding and classification using JZFZ equipment. It is used for wire cutting of potassium arsenide and quartz crystals. It is an engineering processing material for the solar photovoltaic, semiconductor, and piezoelectric crystal industries. Silicon carbide micron powder requires dispersion treatment using a stirring device during production and processing.

[0003] Existing silicon carbide micro powder mixing devices mostly use ordinary cylindrical barrels with smooth inner walls. During the mixing process, the material moves as a whole along the mixing direction, but there is no relative dispersion movement between silicon carbide powders, resulting in low dispersion efficiency of silicon carbide materials.

[0004] To address this issue, a silicon carbide micropowder stirring and dispersing device was proposed, which has the advantage of facilitating efficient dispersion of silicon carbide micropowder, thereby solving the problems mentioned in the background technology. Utility Model Content

A first motor is fixedly installed on the top of the inner cylinder, and a stirring paddle is fixed to the output end of the first motor via a coupling. An outer cylinder is installed around the outer cylinder, and a ball bearing is installed in the gap between the inner and outer cylinders.

A gear ring is fixed to the outer wall of the inner cylinder, and the gear ring meshes with the gear. A feed nozzle is connected to the left side of the top surface of the inner cylinder, and a discharge nozzle is connected to the bottom of the inner cylinder, with the discharge nozzle of the inner cylinder extending to the bottom of the outer cylinder.

[0007] As a further description of the above technical solution: a maintenance shell is welded to the left side wall of the inner cylinder, and a maintenance port is opened on the end face of the maintenance shell, and a maintenance cover plate is provided on the outer surface of the maintenance shell corresponding to the maintenance port.

[0012] This utility model has the following beneficial effects:

The left side of the top surface of the inner cylinder 1 is connected to the feed nozzle 6, and the bottom of the inner cylinder 1 is connected to the discharge nozzle 7. The discharge nozzle 7 of the inner cylinder 1 extends to the bottom of the outer cylinder 2. In order to realize the intermittent forward and reverse rotation of the second motor 9, the second motor 9 is also equipped with a servo controller and uses analog control or pulse control method for forward and reverse rotation drive. This is a known prior art. For those skilled in the art, it is sufficient to perform debugging and operation according to the requirements of its instruction manual. The wiring diagram of the power component and the supply of power are common knowledge in the art and will not be described in detail here.

[0022] In one embodiment, a maintenance shell 12 is welded to the left side wall of the inner cylinder 1, and a maintenance port is provided on the end face of the maintenance shell 12. A maintenance cover plate 18 is provided on the outer surface of the maintenance shell 12 corresponding to the maintenance port. With this structure, the maintenance cover plate 18 facilitates the maintenance of the second motor 9 in the later stage.

[0023] In one embodiment, the dispersing plate 16 has a generally toothed structure, and the toothed portion of the dispersing plate 16 forms several U-shaped notches. The several conical spikes 19 of the auxiliary stirring rod 17 are all arranged towards the several U-shaped notches of the dispersing plate 16. The toothed dispersing plate 16 can directly act on agglomerated or small clustered silicon carbide micro powder, making it easy to stir and comb the silicon carbide micro powder and increase the dispersion effect.

[0024] In one embodiment, an annular guide shell 14 is welded to the bottom inner side of the outer cylinder 2, and an annular slide is formed inside the annular guide shell 14. A guide ring 13 is welded to the bottom of the inner cylinder 1, and the guide ring 13 extends to the inner side of the annular slide of the annular guide shell 14.

[0027] Working principle:

[0028] In use, silicon carbide micro powder is first poured into the inner cylinder 1 through the feed nozzle 6, and then the feed nozzle 6 is sealed. When stirring and dispersing, the first motor 4 is started, causing the stirring paddle 5 at its output end to rotate. This causes the stirring rods 15 mounted on the surface of the stirring paddle 5 to rotate. Since each stirring rod 15 has a comb-shaped dispersing plate 16 welded to its bottom, and the U-shaped notch of the dispersing plate 16 corresponds to the conical spikes 19 on the surface of the auxiliary stirring rod 17, the dispersing plates 16 of the stirring rod 15 rotate with the rotation of the stirring paddle 5. The conical spikes 19 of the auxiliary stirring rod 17 stir and comb the silicon carbide micro powder. At the same time, the second motor 9 is started by the servo controller to drive the gear 10 at its output end to rotate intermittently in both directions. Since the gear ring 11 on the outer wall of the inner cylinder 1 meshes with the gear 10 and the ball bearing 3 is installed between the inner cylinder 1 and the outer cylinder 2, the gear 10 drives the inner cylinder 1 to rotate intermittently in both directions, thereby achieving efficient dispersion of silicon carbide micro powder. After the silicon carbide micro powder is sufficiently dispersed and stirred, the valve of the discharge nozzle 7 is opened to discharge the silicon carbide micro powder.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
