Description

Technical Field

[0001] The utility model relates to the technical field of diamond processing, and particularly relates to a reactor for diamond forming. Background Art

[0002] A diamond coating machine is an efficient and advanced superhard material preparation device. It adopts advanced air flow crushing technology. Through high-pressure gas, diamond particles are impacted into micron level and coated in a metal or non-metal matrix to obtain excellent properties such as high strength, high wear resistance, and high heat resistance.

[0003] The diamond coating machine mainly consists of a feed inlet, a crushing chamber, a coating chamber, a high-pressure gas generator, a control system, etc. The feed inlet is used to add diamond particles to be crushed into the machine. The rotating blades in the crushing chamber crush the diamond particles into micron level at high speed and then enter the coating chamber through a pipeline. The coating chamber is equipped with a metal or non-metal matrix, and the micron-level diamond particles are coated in the matrix, thus forming a high-performance composite material. The working principle is mainly to generate high-pressure gas through the high-pressure gas generator, bring the crushed diamond particles into the coating chamber through the pipeline, and at the same time heat the metal or non-metal matrix to soften it and coat the diamond particles in it. The high-pressure gas can also clean the coated samples to remove excess impurities and residues.

[0004] At present, most of the coating chambers of diamond coating machines on the market adopt cylindrical reactors, which are small in volume and have unreasonable internal structures, resulting in slow fluidization of metal powder and diamond particles and low production efficiency. And when the cylindrical reactor is installed on the coating machine, there are problems of poor stability during operation, easy shaking, and affecting normal production.

[0024] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects of the present utility model as follows.

[0025] As Figures 1-3 shown, a reactor for diamond forming includes a reaction tank 1 and a positioning assembly 2, and the bottom of the reaction tank 1 is fixed on the positioning assembly 2; the reaction tank 1 includes an upper tank body 101 and a lower tank body 102, the upper tank body 101 is cylindrical, and the lower tank body 102 is frustum-shaped; the positioning assembly 2 includes a left flange 202 and a right flange 201, the left flange 202 is semi-circular, the right flange 201 is U-shaped, and a positioning groove 207 for positioning the reaction tank 1 is formed between the left flange 202 and the right flange 201.

[0026] Specifically, the height of the cylinder of the upper tank body 101 is much greater than the height of the frustum of the lower tank body 102, and the frustum of the lower tank body 102 has a structure with a larger upper part and a smaller lower part, so that when the diamond is wrapped, the wrapped diamond can quickly settle and then enter the wrapping machine.

[0027] In this application, different from the traditional fixing method, such as using a single flange to fix the reaction tank 1. Instead, the reaction tank 1 is fixed by two asymmetric flanges on the left and right. Among them, the arc length of the arc side of the right flange 201 is less than the arc length of the arc side of the left flange 202. That is, the size of the U-shaped right flange 201 is smaller than the size of the semi-circular left flange 202. This asymmetric design can effectively reduce the vibration that occurs during the wrapping process of the diamond in the reaction tank 1, so that the reaction tank 1 can be more stably installed on the wrapping machine.

[0028] To stably connect the left flange 202 and the right flange 201, the left flange 202 and the right flange 201 are fixedly connected by a first screw 205. The first screw 205 sequentially passes through the first connection hole at the U-shaped opening of the right flange 201 and the second connection hole on the straight side of the left flange 202. There is an internal thread in the second connection hole, and by tightening the first screw 205, the fixation of the left flange 202 and the right flange 201 is achieved.

[0029] To better fix the reaction tank 1 on the wrapping machine, a gasket 203 is provided below the left flange 202 or the right flange 201, and the left flange 202 or the right flange 201 is connected to the gasket 203 by a second screw 206. A sealing ring 204 is sleeved on the outer periphery of the gasket 203.

[0030] Among them, the gasket 203 is located below the flange. Through holes are provided at corresponding positions on the flange and the gasket 203, and the second screw 206 passes through the through holes for fixation. According to different working conditions, there can be multiple second screws 206, which are respectively installed at different positions on the left flange 202 and the right flange 201.

[0031] Furthermore, a tank base 103 is provided below the lower tank body 102. The tank base 103 is in a disc shape, and the diameter of the tank base 103 is larger than the bottom diameter of the lower tank body 102. An installation hole is provided at the center of the gasket 203, and the tank base 103 is placed in the installation hole. The upper tank body 101, the lower tank body 102, and the tank base 103 are integrally formed by glass material processing.

[0032] Applying the tank base 103 can increase the bottom area of the reaction tank 1, so that when the reaction tank 1 is fixed to the positioning assembly 2, the stability can be further improved.
