Description

Technical Field

[0001] The invention relates to the technical field of processing equipment for silicon micropowder production, in particular to a silicon carbide micropowder purification device. Background Art

[0002] Silica powder purification is an important process, which aims to increase the content of silicon dioxide (SiO2) in silica powder and remove impurities, so as to expand its application field and improve economic benefits. The content of SiO2 is the main criterion for measuring the quality of silica powder. Silica powder sold on the market often contains impurities such as metal oxides and free carbon. These impurities limit the application field of silica powder and lead to low economic benefits. Through purification, the price of silica powder can be significantly increased and its application field can be expanded.

[0003] In the process of silicon micropowder purification, acid washing, acid leaching and microwave acid leaching are used to remove various metal oxides and other impurities in the sample, thereby increasing the SiO2 content in the silicon micropowder. However, due to the special nature of its internal impurities, some impurities contained inside cannot react fully, thus affecting the purification effect. Summary of the invention

[0004] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides a silicon carbide micropowder purification device, which solves the problem that due to the particularity of the impurities inside, some impurities wrapped inside cannot fully react, thus affecting the purification effect.

[0005] (II) Technical solution To achieve the above purpose, the present invention is implemented through the following technical solutions: a silicon carbide micropowder purification device, including a processing box and a servo motor, two negative pressure fans are arranged inside the processing box, and the positions of the two negative pressure fans are symmetrically distributed about the center position of the processing box, the driving end of the servo motor penetrates the side wall of the processing box and extends to the inside thereof and is fixedly connected to the central axis of one of the negative pressure fans, and a purification mechanism is arranged inside the processing box, and the purification mechanism includes two adjusting screws, the positions of the two adjusting screws are distributed up and down, the two adjusting screws are connected by transmission belt transmission, the outer surfaces of the two adjusting screws are threadedly sleeved with two mounting seats, the positions of the two mounting seats are symmetrically distributed about the middle position of the adjusting screw, the mounting seat is close to the side wall of the processing box and is slidably connected thereto, the outer surface thread of the adjusting screw is divided into two sections with equal length and opposite rotation direction, the side walls of multiple mounting seats away from the inner side wall of the processing box are rotatably connected with a connecting shaft, the outer surface of the connecting shaft is fixedly sleeved with an adjusting gear, and one end of multiple connecting shafts away from the mounting seat is fixedly connected with a de-impurity plate.

[0006] Preferably, the central axis of the negative pressure fan which is not fixedly connected to the driving end of the servo motor is transmission-connected to the two adjusting screws via a transmission belt.

[0007] Preferably, a plurality of fixed tooth plates are provided on both the front and rear sides of the two adjusting screw rods, and the positions of the plurality of fixed tooth plates are distributed in a staggered manner.

[0008] Preferably, a plurality of honeycomb holes are provided on the side wall of the impurity removal plate.

[0009] Working principle: When in use, place the silicon micropowder solution to be treated inside the treatment box, start the servo motor, and the driving end of the servo motor drives one of the negative pressure fans to drive the two adjusting screws to perform fixed-cycle forward and reverse motion through the transmission belt. At this time, the two negative pressure fans will also rotate continuously, and the negative pressure generated by rotation drives the silicon micropowder solution to continuously move in the direction of the two impurity removal plates, thereby increasing the relative movement of the two, and also increasing the contact degree between the acid and the solution. When the material is hit by the negative pressure on the impurity removal plate, the wrapped material is exposed, thereby improving the treatment effect. During the treatment process, when the adjusting screw rotates, the mounting seat on the outer surface of the threaded sleeve will move along the direction of the adjusting screw. During the movement of the mounting seat, the adjusting gear above it will continuously perform forward and reverse motion under the action of the fixed tooth plate, thereby further breaking up the flocculated material and improving the reaction degree and treatment effect.

[0010] (III) Beneficial effects The present invention provides a silicon carbide micropowder purification device, which has the following beneficial effects: 1. In the silicon carbide micropowder purification device, the two negative pressure fans will continuously rotate, and the negative pressure generated by rotation drives the silicon micropowder solution to continuously move toward the two impurity removal plates, thereby increasing the relative movement degree between the two and the contact degree between the acid and the solution. When the material is hit by the negative pressure on the impurity removal plate, the wrapped material is exposed, thereby improving the treatment effect.

[0011] 2. In the process of processing, when the adjusting screw rod rotates, the mounting seat with the threaded sleeve on its outer surface will move along the direction of the adjusting screw rod. During the movement of the mounting seat, the adjusting gear above it will continuously perform forward and reverse motions under the action of the fixed tooth plate, thereby further breaking up the flocculated materials and improving the reaction degree and processing effect.
