The technical solution provided by the present invention will be described in detail by way of examples with reference to the accompanying drawings. It should be noted that the description of these examples is for aiding in understanding the present invention, but is not intended to limit the present invention.
In some instances, some embodiments are not described or described in detail as such, as may be known or conventional in the art.
Furthermore, features described herein, or steps in all methods or processes disclosed, may be combined in any suitable manner in one or more embodiments in addition to mutually exclusive features and/or steps. It will be readily understood by those skilled in the art that the steps or order of operation of the methods associated with the embodiments provided herein may also be varied. Any order in the figures and examples is for illustrative purposes only and does not imply that a certain order is required unless explicitly stated that a certain order is required.
The numbering of the components itself, e.g. "first", "second", etc., is used herein merely to distinguish between the described objects and does not have any sequential or technical meaning. The term "coupled" as used herein includes both direct and indirect coupling (coupling) where appropriate (where no paradox is constructed).
As shown in fig. 1 and 2, the cylinder body of the embodiment sequentially comprises an inner cylinder 1, an outer cylinder 2, a heat insulation layer 3 and a shell 4 from inside to outside, a spiral runner 5 is arranged between the inner cylinder 1 and the outer cylinder 2, the spiral center of the runner 5 coincides with the center of the cylinder body, the upper end and the lower end of the runner 5 are respectively communicated with the outside of the cylinder body, the heat insulation layer 3 is coated on the surface of the outer cylinder 2, and the shell 4 is coated on the surface of the heat insulation layer 3.
The outer cylinder 2 is fitted over the inner cylinder 1, and in order to facilitate assembly and to enable the heat transfer medium to flow through the flow channel 5 instead of through the gap between the inner cylinder 1 and the outer cylinder 2, in this embodiment the inner cylinder 1 and the outer cylinder 2 are in a transition fit. Further, a sealing ring may be disposed between the inner cylinder 1 and the outer cylinder 2, specifically, grooves for accommodating the sealing ring are formed at two ends of an inner hole of the inner cylinder 1 or two ends of an outer circle of the outer cylinder 2, and the sealing ring is placed in the grooves, so that it is understood that the flow channel 5 is located between the two sealing rings.
The flow channel 5 can be arranged on the outer circular surface of the inner cylinder 1, namely, an external thread-shaped groove is processed on the outer circular surface of the inner cylinder 1, and the external thread-shaped groove is the flow channel 5; the runner 5 can also be arranged on the inner circular surface of the outer cylinder 2, namely, the inner circular surface of the outer cylinder 2 is processed with an internal thread-shaped groove, and the internal thread-shaped groove is the runner 5; thread grooves are machined on the outer circular surface of the inner cylinder 1 and the inner circular surface of the outer cylinder 2 at the same time, and the thread grooves on the outer circular surface of the inner cylinder 1 and the thread grooves on the inner circular surface of the outer cylinder 2 are spliced to form a flow passage 5, so that the alignment of the thread grooves on the outer circular surface of the inner cylinder 1 and the thread grooves on the inner circular surface of the outer cylinder 2 is difficult to ensure after splicing; further, since the external thread is easier to machine than the internal thread, in the present embodiment, as shown in fig. 2, the flow passage 5 is opened in the outer circumferential surface of the inner cylinder 1.
In this embodiment, as shown in fig. 1, the cylinder further includes two end rings 6 respectively located at both ends of the cylinder, the inner diameter of the end ring 6 is adapted to the outer diameter of the outer cylinder 2, and the heat insulating layer 3 and the outer shell 4 are located between the end rings 6 at both ends. The two end rings 6 and the shell 4 enclose an annular cavity which can be used as the heat insulation layer 3, and the cavity can be filled with heat insulation materials or filled with media for heat insulation or cooling. When the medium is injected into the cavity, the end ring 6 and the housing 4 can be welded together, or a sealing ring can be arranged between the end ring 6 and the opposite surface of the housing 4.
In the present embodiment, as shown in fig. 1, the end rings 6 are provided with heat circulation ports 7 communicating with the flow passages 5, and the heat circulation ports 7 of the two end rings 6 are an inlet and an outlet, respectively. The heat transfer medium can directly enter and exit the runner 5 through the heat circulation port 7, and at this time, a seal is required to be added at the place where the heat circulation port 7 is connected with the outer cylinder 2. In this embodiment, as shown in fig. 1, the outer wall of the outer cylinder 2 is provided with a threaded hole communicating with the flow passage 5, the threaded hole is a seal cone threaded hole, and the thermal cycle ports 7 are each provided with a pipe 8, and the pipe 8 is in threaded engagement with the threaded hole.
In the present embodiment, the heat circulation port 7 on the end ring 6 at the lower end of the cylinder is an inlet, and the heat circulation port 7 on the end ring 6 at the upper end of the cylinder is an outlet, and since the inlet of the heat transfer medium is downward and the outlet is upward, the direction of gravity of the heat transfer medium is the same, thereby ensuring uniform distribution of the heat transfer medium along the axis direction of the cylinder, and improving temperature uniformity.
In the present embodiment, as shown in fig. 1, a seal structure 9 is provided between the end ring 6 and the outer cylinder 2. Specifically, an annular groove for accommodating the sealing ring is formed in the inner circular surface of the end ring 6 or the outer circular surface of the outer cylinder 2, and the sealing ring is arranged in the annular groove.
In the present embodiment, as shown in fig. 1, the outer case 4 is flush with the outer circumferential surface of the end ring 6.
The invention also provides a warm isostatic pressing machine, which comprises the cylinder body of any one of the above, wherein the upper end of the cylinder body is matched with a cylinder cover 10, and the lower end of the cylinder body is fixed with a base 11.
