Description

Technical Field

[0001] This invention relates to the field of silicon micropowder processing equipment technology, specifically to a silicon micropowder airflow pulverizing device. Background Technology

[0002] Silica powder is a micro powder produced from natural quartz or fused quartz through multiple processes such as crushing, ball milling, flotation, acid washing and purification, and high-purity water treatment. Due to its excellent performance, silica powder is widely used in many fields and is an important inorganic non-metallic functional filler that plays a vital role in many areas.

[0003] Traditional silicon micropowder processing equipment not only has low crushing efficiency, but also the screen plates are prone to clogging, affecting the processing effect. Summary of the Invention

[0004] (a) Technical problems to be solved In view of the shortcomings of the prior art, the present invention provides a silicon micro powder airflow pulverizing device, which solves the problem that excessive lubricating oil cannot be well recovered, which not only easily contaminates the chain, but also causes waste of resources.

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a silicon micropowder airflow pulverizing device, comprising a processing box and a servo motor. The drive end of the servo motor extends through the side wall of the processing box into its interior and is fixedly connected to a central rod. A negative pressure fan is installed inside the processing box. The central rod passes through the center of the negative pressure fan and is fixedly connected to the fan blades. Multiple transmission rods are installed inside the processing box. The ends of the multiple transmission rods are connected by transmission cylinders and transmission teeth. The end of the central rod furthest from the servo motor is connected to the transmission rod closest to it via transmission cylinders and transmission teeth. Multiple driving teeth are fixedly connected to the inner side walls of the multiple transmission cylinders. The multiple driving teeth fixedly connected to the inner side wall of the same transmission cylinder are arranged in a circular array. The transmission rod located at the last position is furthest from its closest position. One end of the transmission rod at the nearest position is rotatably connected to the inner wall of the processing box. The outer surface of the multiple transmission rods is rotatably fitted with a limiting cylinder. The limiting cylinder is fixedly connected to the inner wall of the processing box through a fixed shaft. Multiple crushing rods are fixedly connected to the outer walls of the multiple transmission rods.

[0006] Preferably, both the drive teeth and the transmission teeth are retractable and adjustable teeth.

[0007] Preferably, the multiple crushing rods fixedly connected to the outer wall of the same transmission rod are arranged in a ring array or in a staggered arrangement around each other.

[0008] Preferably, the processing box is provided with a sieve plate inside. The end of the transmission rod located at the last position, away from its nearest position, passes through the sieve plate. An installation opening is provided at the center of the sieve plate. A transmission flexible shaft is fixedly connected to the inner side wall of the installation opening. A drive shaft is fixedly connected to the outer surface of the transmission rod located at the last position, away from its nearest position. The drive shaft is located inside the installation opening. The gap between the installation opening and the transmission rod is closed by a cover plate.

[0009] Working principle: During use, place the silicon powder to be pulverized below the servo motor, open the feed port located below it, and start the servo motor. The drive end of the servo motor drives the central rod, which in turn rotates the negative pressure fan at high speed. This generates negative pressure, driving the silicon powder towards the sieve plate. As the silicon powder moves towards the sieve plate, the transmission cylinder transmits power to the transmission rod through the drive teeth on its inner wall and the transmission teeth on the outer surface of the transmission rod. Adjacent transmission rods also transmit power in this way, thereby driving the pulverizing rod on the outer surface of the central rod to rotate. As the silicon powder moves under the influence of airflow... The silicon powder is dispersed by adjusting the transmission and drive teeth, which are both telescopic and adjustable. This allows for changes in the transmission ratio, thereby adjusting the rotation speed of the crushing rods on the outer surface of each transmission rod, creating a differential rotation mode. This, combined with the airflow of the silicon powder, gradually disperses the material, achieving a thorough crushing effect. The dispersed material passes through a sieve plate and is collected on the other side. During processing, the sieve plate is intermittently driven by the drive shaft via a flexible transmission shaft. Under inertia, it rotates and oscillates, preventing excessive material adsorption and blockage, thus ensuring the processing effect.

[0010] (III) Beneficial Effects This invention provides a silicon micropowder airflow pulverizing device. It has the following beneficial effects: 1. This silicon micro powder airflow pulverizing device has adjustable transmission teeth and drive teeth, which can change the transmission ratio and thus adjust the rotation speed of the pulverizing rod on the outer surface of each transmission rod, creating a differential rotation mode. This, combined with the movement of the silicon micro powder airflow, gradually disperses the silicon micro powder material, achieving a thorough pulverizing effect.

[0011] 2. In this silicon micro powder airflow pulverizing device, during the processing, the sieve plate is intermittently driven by the drive shaft through the transmission flexible shaft. Under the action of inertia, it will rotate and oscillate, avoiding excessive adsorption of materials and causing blockage, thus ensuring the processing effect. Attached Figure Description
