Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-2, an efficient high-temperature melt granulation apparatus includes a high-pressure gas inlet pipe 1, a high-pressure gas distribution chamber 2, and a high-pressure gas acceleration air duct 3, wherein the high-pressure gas distribution chamber 2 is disposed at one end of the high-pressure gas inlet pipe 1, the high-pressure gas acceleration air duct 3 is clamped inside the high-pressure gas distribution chamber 2, a pipe through groove 4 of a hollow cylindrical structure is disposed inside the high-pressure gas inlet pipe 1, a protection ring 5 is laid on an edge of the high-pressure gas distribution chamber 2, an upper chamber end 6 is disposed at one end of the high-pressure gas distribution chamber 2, and a lower chamber end 7 is disposed at the other end of the high-.
As a technical optimization scheme of the invention, the high-pressure gas inlet pipe 1, the high-pressure gas distribution chamber 2 and the high-pressure gas acceleration air duct 3 are communicated with each other, so that gas can quickly pass through the high-pressure gas inlet pipe 1 and is accelerated through the high-pressure gas acceleration channel 3 to form a 'gas bed'.
As a technical optimization scheme of the invention, the high-pressure gas accelerating air duct 3 is of a hollow internal spiral cylindrical structure, so that the path of gas accelerated is longer, and the flow rate of the accelerated gas is stronger and higher.
As a technical optimization scheme of the invention, the protective ring 5 is arranged in an inward concave shape, the high-pressure gas accelerating air duct 3 penetrates through the protective ring 5, and the width of the protective ring 5 is matched with that of the high-pressure gas distribution chamber 2, so that the protective ring 5 can cover the high-pressure gas distribution chamber 2 more tightly, and the protective strength is higher.
As a technical optimization scheme of the invention, the upper chamber end 6 and the lower chamber end 7 are symmetrically arranged, and the side walls of the upper chamber end 6 and the lower chamber end 7 are respectively provided with the sealing baffle plate, so that the sealing performance of the high-pressure gas distribution chamber 2 is higher, gas leakage during gas feeding acceleration is avoided, and the gas acceleration strength is improved.
As a technical optimization scheme of the invention, the high-pressure gas inlet pipe 1 and the high-pressure gas distribution chamber 2 are vertically arranged, and a T-shaped structure is formed between the high-pressure gas inlet pipe 1 and the high-pressure gas distribution chamber 2, so that gas can be accurately introduced into the high-pressure gas acceleration air duct 3 to be accelerated into an air bed after flowing through the high-pressure gas inlet pipe 1.
When the granulating device is used, firstly, the whole high-temperature melt granulating device is fixed in position, secondly, the granulating device is started to form a high-speed air bed before the high-temperature melt is discharged when the granulating device is used, high-pressure air enters the high-pressure air distribution pipe 2 through the high-pressure air inlet pipe 1, and after the high-pressure air is uniformly distributed, the high-pressure air is instantaneously accelerated to a target speed in the high-pressure air acceleration air duct 3. Then, the high-temperature melt begins to be discharged, and is immediately shredded into fine particles after entering a high-speed 'air bed'. Because the existence of high-speed "air bed" has replaced the work content of mechanical or manual work clearance high temperature melt chute export "ends beard", seals the tip of high-pressure gas distribution chamber 2 through upper chamber end 6 and lower chamber end 7 that are the symmetry setting, avoids high-pressure gas to leak, keeps off through guard ring 5 high-pressure gas distribution chamber 2 and props the protection, avoids the device to receive external force striking to lead to damaging at the during operation.
