Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to a glass annealing device for an X-ray tube. Background Art

[0002] In modern society, with the continuous advancement of medical technology, the medical application of X-rays is becoming more and more important. For X-ray medical equipment, the most important one is the X-ray tube. The rotating anode X-ray tube assembly is the core part of the X-ray generating device. The rotating anode X-ray tube assembly is composed of the rotating anode X-ray tube core, the tube sleeve and all the components that fix the tube core in the tube sleeve.

[0003] In the process of sealing X-ray tubes, the glass shell often cracks at the sealing point. This is because glass itself is not easy to conduct heat and has a large thermal expansion coefficient. During the heating process, if the temperature and time are not properly controlled, internal stress is likely to occur. When the internal stress exceeds the tensile strength of the glass, the glass is likely to crack.

[0004] Therefore, how to ensure uniform temperature at the glass bulb to reduce the internal stress at the seal is an urgent problem to be solved. Summary of the invention

[0005] The object of the present invention is to overcome the shortcomings of the prior art and provide a glass annealing device for an X-ray tube.

[0008] Preferably, the outer contour of the shell is a truncated cone with a diameter gradually decreasing upward, and the cross-section of its inner cavity is circular. The diameter of the convex disk is larger than the diameters of the concave disk, the porous disk and the center hole disk, and the two sides of the convex disk are fastened together with the shell and the sealing gasket by fastening screws. The concave disk, the porous disk and the center hole disk have the same diameter and the bottoms of their side walls are abutted in sequence, the bottom of the side wall of the concave disk abuts against the surface of the convex disk, and the top of the side wall of the center hole disk abuts against the top bottom surface of the shell.

[0022] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments are not limited to the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Moreover, in the description of the scheme, with the operator as a reference, the direction close to the operator is the proximal end, and the direction away from the operator is the distal end.

[0024] like Figure 1 to Figure 2As shown, the present invention discloses a glass annealing device for an X-ray tube, comprising a handle 1 and a connector, wherein the handle 1 and the connector are sealed and connected via a sealing gasket 2, and a propane gas pipe 3 and an air gas pipe 4 for air intake are arranged in the handle 1. The connector is composed of a shell 5 and a group of partition components through which gas can flow, wherein the partition components are arranged inside the shell 5 and separate the inside into at least three interconnected gas mixing zones, wherein the top of the shell 5 has a central through hole 501 and side holes 502 uniformly distributed around the central through hole 501, wherein the diameter of the central through hole 501 is larger than that of the side holes 502 and the height thereof is higher than that of the side holes 502. In this preferred embodiment, the structure of the central through hole 501 helps to quickly ignite the side holes 502 with a smaller diameter and a faster flow rate, and the side holes 502 densely and uniformly distributed on the top of the shell 5 help to uniformly output the gas so that the flame burns uniformly.

[0025] The propane gas pipe 3, the air gas pipe 4, the central through hole 501 and the side hole 502 are all connected to the gas mixing area.

[0026] Specific as Figure 2 As shown, the partition assembly includes a convex plate 6, a concave plate 7, a porous plate 8 and a center hole plate 9 which are coaxially arranged from bottom to top and have side walls matching the inner wall of the shell 5. There are gaps between the convex plate 6, the concave plate 7, the porous plate 8 and the center hole plate 9, and there is also a gap between the center hole plate 9 and the top of the shell 5.

[0027] Furthermore, the gap between the concave plate 7 and the porous plate 8 is the first gas mixing zone 100, the gap between the porous plate 8 and the central hole plate 9 is the second gas mixing zone 200, and the gap between the central hole plate 9 and the top of the shell 5 is the third gas mixing zone 300. The structural arrangement of the three gas mixing zones can ensure the full mixing between the air and the propane gas, and ensure that the mixed gas output from the central through hole 501 and the side hole 502 is as uniform as possible, so as to generate a uniform flame to ensure the uniform temperature around the glass shell (not shown in the figure) of the X-ray tube. In other feasible embodiments, more than three gas mixing zones can also be set.

[0028] In a preferred embodiment of the present invention, the outer contour of the shell 5 is a truncated cone with a diameter gradually decreasing upward, and the cross section of its inner cavity is circular to fit the shape of the glass shell as much as possible. Therefore, the convex disk 6, the concave disk 7, the porous disk 8 and the center hole disk 9 are all circular. Specifically, the diameter of the convex disk 6 is larger than the diameter of the concave disk 7, the porous disk 8 and the center hole disk 9, and the two sides of the convex disk 6 are fastened together with the shell 5 and the sealing gasket 2 by fastening screws 10. The bottom of the shell 5 has a groove with a diameter larger than its inner cavity, and the side of the convex disk 6 is clamped in the groove. The sealing gasket 2 fits tightly with the shell 5 to limit the position of the convex disk 6, and the fastening screw 10 is inserted into the side wall of the shell 5 from the bottom of the sealing gasket 2 to fasten the shell 5, the convex disk 6 and the sealing gasket 2 together.

[0029] Furthermore, the concave disk 7, the porous disk 8 and the center hole disk 9 have the same diameter and the bottoms of their side walls are abutted in sequence, the bottom of the side wall of the concave disk 7 abuts the surface of the convex disk 6, and the top of the side wall of the center hole disk 9 abuts the top bottom surface of the shell 5. Such a structure can not only ensure the stability of the concave disk 7, the porous disk 8 and the center hole disk 9 inside the shell 5, but also eliminate the need for screw connection, simplify the internal structure of the shell 5, save the internal space of the shell 5, and reduce the manufacturing cost.

[0030] In this preferred embodiment, the center of the convex disc 6 has a first inner hole 601 protruding upward, and the first inner hole 601 is connected to the air pipe 4; the side of the convex disc 6 has a second inner hole 602 flush with its surface, and the second inner hole 602 is connected to the propane pipe 3. Of course, in other feasible embodiments, the first inner hole 601 can also be connected to the propane pipe 3, and the second inner hole 602 can also be connected to the air pipe 4. In addition, the terminals of the propane pipe 3 and the air pipe 4 are both provided with control valves (not shown in the figure) for controlling the air flow, so as to help accurately control the gas flow in the propane pipe 3 and the air pipe 4, so as to control the size of the flame. It is also due to this structure that the propane gas output from the second inner hole 602 can be gathered along the side wall of the first inner hole 601 to the first inner hole 601, and flow through the concave hole 701 of the concave disc 7 together.

[0031] The concave hole 701 is arranged at the center of the concave plate 7, and is coaxial with the first inner hole 601. The bottom opening diameter of the concave hole 701 is larger than the first inner hole 601, and the connection 702 between the bottom opening and the bottom surface of the concave plate 7 is an arc surface, and the first inner hole 601 and the second inner hole 602 are connected to the first gas mixing zone 100 through the concave hole 701. The bottom opening diameter of the concave hole 701 is larger than the first inner hole 601, so that the gas output from the propane gas pipe 3 and the air gas pipe 4 can quickly enter the first gas mixing zone 100.

[0032] Furthermore, the top of the concave hole 701 protrudes from the surface of the concave plate 7, and the opening diameter of the concave hole 701 gradually expands from the bottom to the top to form a trumpet shape. The trumpet-shaped concave hole 701 helps to further accelerate the flow rate of the gas entering the first gas mixing area 100, and the top of the concave hole 701 protrudes from the surface of the concave plate 7, resulting in an uneven surface of the concave plate 7, thereby promoting the flow of air and propane gas in the first gas mixing area 100, thereby ensuring sufficient mixing between the air and propane gas.

[0033] Similarly, a group of flow holes 801 connecting the first gas mixing area 100 and the second gas mixing area 200 are evenly distributed on the side of the porous disk 8. The bottom surface of the porous disk 8 has a tip 802 coaxial with the concave hole 701. The tip 802 extends into the concave hole 701 and does not contact the concave hole 701 and the first inner hole 601. The top surface of the porous disk 8 has an annular groove 803. The setting of the tip 802 allows the gas in the first gas mixing area 100 to form a diversion guide. The groove 803 helps to expand the capacity of the second gas mixing area 200, and makes the surface of the porous disk 8 uneven, forming turbulence, which helps the gas in the second gas mixing area 200 to be fully mixed.

[0034] Further, the top surface of the central hole plate 9 is concave, and the center of the central hole plate 9 has a vent hole 901 with a bottom opening protruding from its bottom surface, the vent hole 901 is coaxial with the central through hole 501 of the shell 5 and is connected to the side hole 502 of the central through hole 501, and the bottom surface of the central hole plate 9 and its side wall are connected in an arc shape. Similarly, the structure in which the vent hole 901 protrudes from the bottom surface of the central hole plate 9 and the side wall of the central hole plate 9 are connected in an arc shape, both help the gas to flow in the second gas mixing zone 200 for full mixing.

[0035] In order to facilitate the operation of the operator, the outer contour of one side of the handle 1 is a continuous arc-shaped side wall 101. Such a setting can increase the friction of the handle, so that the operator can hold it conveniently and anneal places in different directions.

[0036] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0037] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the present invention. They are not intended to limit the scope of protection of the present invention. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the present invention should be included in the scope of protection of the present invention.
