Description

Technical Field

[0001] This invention belongs to the field of diamond micron powder shaping technology, specifically relating to a continuous diamond micron powder shaping device and method. Background Technology

[0002] Currently, diamond micron powder is produced using synthetic diamond single crystals as raw materials, through processes such as crushing, shaping, purification, sorting, and drying. Compared with coarse-grained powder materials, its specific surface area is significantly increased, thus significantly enhancing the interaction between particles during production. In addition, as the particle size is refined, the defects in the particles themselves decrease, inevitably increasing the strength. It is evident that the production process of diamond micron powder is quite challenging, as it involves not only particle refinement but also changes in crystal structure and surface physicochemical properties. Therefore, the production process of diamond micron powder is an engineering and technical problem involving multiple disciplines such as mechanics, powder engineering, mechanics, physics, chemistry, and modern instrumentation and measurement technology. Shaping is a crucial process in the preparation of diamond micron powder.

[0003] Airflow shaping is a shaping device that uses the strong multiphase turbulent flow field formed when a high-speed airflow is ejected to cause particles to collide and rub against each other or collide and rub against the inner wall of the equipment, thus causing the particles to be crushed. During the process of shaping diamond micro powder by the airflow shaping machine, some of the heavier micro powder that has not been shaped properly will fall to the bottom of the shaping cylinder under the action of gravity, and then be discharged with the micro powder that has completed the shaping operation, thus affecting the quality of diamond micro powder. Summary of the Invention

[0004] To address the problems mentioned in the background section, this invention provides a continuous diamond micron powder shaping device and method, featuring a two-stage shaping process.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a continuous diamond micron powder shaping device and method, comprising a support plate, a collection box, an air pump, and three support rods fixedly connected to the top of the support plate, a shaping cylinder fixedly connected to the top of the support rods, a stirring motor, a connecting pipe, and a vacuum feeder fixedly connected to the top of the shaping cylinder, a feeding valve fixedly connected to the surface of the connecting pipe, an air pipe fixedly connected to the output end of the air pump, the output end of the air pipe passing through the shaping cylinder and located at the bottom of the shaping cylinder, an air outlet fixedly connected to the output end of the air pipe, a discharge pipe fixedly connected to the side of the shaping cylinder, the output end of the discharge pipe fixedly connected to the top of the inside of the collection box, a return pipe fixedly connected to the top of the vacuum feeder, the input end of the return pipe fixedly connected to the inside side of the collection box, a filter plate fixedly connected to the inside side of the collection box, and a collection hopper slidably connected inside the collection box.

[0006] Preferably, an air outlet pipe is fixedly connected to the top of the collection box, and a fiber breathable layer is fixedly connected inside the air outlet pipe.

[0007] Preferably, the output end of the agitator motor rotates through the shaping cylinder and is fixedly connected to a rotating shaft, the surface of which is fixedly connected with multiple contact spherical grinding blocks.

[0008] Preferably, a connecting plate is fixedly connected to the side of the support plate, a conveying motor is fixedly connected to the top of the connecting plate, a conveying pipe is fixedly connected to the top of the connecting pipe, the output end of the conveying motor rotates through the conveying pipe, and is fixedly connected to an auger.

[0009] Preferably, a connecting plate is fixedly connected to the side of the support plate, a conveying motor is fixedly connected to the top of the connecting plate, a conveying pipe is fixedly connected to the top of the connecting pipe, the output end of the conveying motor rotates through the conveying pipe, and is fixedly connected to an auger.

[0010] Preferably, a support pad is fixedly connected to the bottom of the support plate, and a first observation window and a second observation window are provided on the front of both the shaping cylinder and the collection box.

[0011] Preferably, it includes the following steps:

[0012] 1. Conveying: The conveyor motor drives the auger to rotate, which can transport the diamond powder in the hopper to the connecting pipe, and then to the shaping cylinder through the connecting pipe.

[0013] II. Shaping Mechanism: The air pump operates, blowing air into the shaping cylinder through the air pipe and air outlet. This causes the diamond micro powder to move and collide with each other, shaping the sharp micro powder. At the same time, the stirring motor operates, causing the rotating shaft and the contact spherical grinding blocks to rotate. As the diamond micro powder moves, the contact spherical grinding blocks further increase friction and improve the shaping effect. After shaping, the diamond micro powder that meets the requirements falls into the collection hopper under the action of the filter plate.

[0014] Third, secondary shaping mechanism: Larger diamond micro powder particles are reintroduced into the shaping cylinder by the vacuum feeder and reflux pipe for secondary shaping.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention, by setting up an air pump and a vacuum feeder, allows the air pump to be operated by an external controller. When the air pump is running, air is blown into the shaping cylinder through the air pipe and air outlet, causing the diamond micro powder to move, collide, and rub against each other, thus shaping the sharp micro powder. After shaping, the diamond micro powder that meets the requirements falls into the collection hopper under the action of the filter plate, while the larger diamond micro powder particles are reintroduced into the shaping cylinder under the action of the vacuum feeder and the return pipe, allowing for secondary shaping.

[0017] 2. In this invention, by setting up a stirring motor, people can rotate the shaft and the contact spherical grinding block by running the stirring motor. When the diamond powder moves, the friction can be further increased under the action of the contact spherical grinding block, thereby improving the shaping effect.

[0018] 3. The present invention, by setting up a conveying motor, a conveying pipe and an auger, makes it convenient for people to pour diamond micro powder into the shaping cylinder. Attached Figure Description
