Description

Technical Field

[0001] The invention relates to the technical field of circumferential machines, and in particular to a temperature reduction and protection device for an anode target of an X-ray circumferential machine. Background Art

[0002] An X-ray circumferential scanner is a device that uses the properties of X-rays penetrating matter and attenuating in matter to detect whether there are defects inside metal and non-metal materials and their products. Its working principle is to use X-rays to penetrate metal materials and, through the different absorption and scattering effects of the materials on the rays, make the film sensitive to different light, thus forming images of different blackness on the film, and based on this, the internal defects of the material can be judged.

[0003] In the patent document of the prior art patent application number 201621316315.8, a directional circumferential X-ray flaw detector for continuous exposure industry is disclosed, and specifically discloses that it includes an upper casing, an annular grooved casing and a lower casing, a high-speed cooling fan is provided in the lower casing, a tower-shaped rectangular radiator is provided above the high-speed cooling fan, an anode target and a directional circumferential X-ray tube window are provided in the middle of the tower-shaped rectangular radiator, a lower head is provided at the upper end of the anode target, the lower head is located between the annular grooved casing and the lower casing, a metal corrugated ceramic X-ray tube, a high-voltage package and a C-type high-voltage transformer core are connected in sequence in the annular grooved casing above the lower head, an upper head is provided above the C-type high-voltage transformer core, and the upper head is located between the upper casing and the annular grooved casing.

[0004] However, in the prior art, the inner walls of the connecting ends on both sides of the valve are inspected through a directional circumferential X-ray tube window. During the inspection process, the position of the X-ray circumferential machine needs to be constantly adjusted to image all the inner walls of the connecting ends on both sides of the valve onto the photosensitive film, which makes the measurement extremely inconvenient. However, by removing the cooling fan and extending the X-ray tube window to the inner wall of the valve, rapid inspection can be performed. However, if the anode target is not cooled during operation, it is very easy to be damaged due to excessive temperature, thereby reducing the service life of the X-ray circumferential machine.

[0027] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0028] See also Figure 1 and Figure 2Specifically, the present invention provides a cooling protection device for an anode target of an X-ray circumferential machine, comprising a circumferential machine body 1, a water tank 2, a cooling component 3, a control component 4 and a moving component 5. The circumferential machine body 1 is fixed on the moving component 5, and the moving component 5 facilitates the movement of the circumferential machine body 1. The cooling component 3 is connected to the water tank 2. The water tank 2 and the cooling component 3 are used to cool the circumferential machine body 1 when it is working. The control component 4 detects whether the heating temperature of the circumferential machine body 1 is too high when it is working, and can send out an alarm so that the operator can find and shut down the circumferential machine body 1 in the first time, thereby avoiding damage to the circumferential machine body 1 due to excessive temperature.

[0029] Among them, the difference between the circumferential body 1 and the existing flaw detector is that the cooling fan is removed, so that the X-ray tube 11 set on the circumferential body 1 and the anode target 12 set in the X-ray tube are directly exposed. The advantage is that it can avoid detecting the valve by constantly adjusting the position of the X-ray tube window, but directly extend the X-ray tube 11 on the circumferential body 1 to the inside of the valve, so that the detection can be completed quickly; the disadvantage is that when the circumferential body 1 is working, the anode target is very likely to be damaged due to excessive temperature.

[0030] The water tank 2 is a component for storing cooling liquid for cooling the anode target. It is provided with a water inlet pipe 21 and a water outlet pipe 22, and is filled with cooling liquid 23. The water inlet pipe 21 is arranged above the water outlet pipe 22, and the liquid level of the cooling liquid 23 is lower than the plane where the lowest point of the water inlet pipe 21 is located. A sewage pipe 24 is arranged on the side wall of the lower end of the water tank 2. By arranging a sewage valve 25 on the sewage pipe 24, the water tank 2 can be cleaned regularly.

[0031] The cooling assembly 3 includes a cooling sleeve 31 fixedly mounted on the X-ray tube 11 for cooling the anode target, a pump unit 32, a first connecting hose 33 and a second connecting hose 34. The liquid inlet of the pump unit 32 is connected to the water outlet pipe 22, and the liquid outlet of the pump unit 32 is connected to the cooling sleeve 31 via the first connecting hose 33. The cooling sleeve 31 is also connected to the water inlet pipe 21 via the second connecting hose 34. Specifically, the pump unit 32 is a commonly used water pump on the market. The lengths of the first connecting hose 33 and the second connecting hose 34 are not limited, as long as it can ensure that the circumferential body 1 can be moved to the corresponding position to detect multiple valves under the action of the moving assembly 5.

[0032] The control assembly 4 includes a control box body 41, a processor 42 fixed in the control box body 41, a first temperature sensor 43 arranged in the water inlet pipe 21, a second temperature sensor 44 arranged in the water outlet pipe 22, and an alarm unit 45 arranged on the outer wall of the control box body 41. The processor 42 is electrically connected to the first temperature sensor 43, the second temperature sensor 44, and the alarm unit 45 respectively. By detecting the temperature difference of the cooling liquid 23 between the water inlet pipe 21 and the water outlet pipe 22 detected by the first temperature sensor 43 and the second temperature sensor 44, the processor controls the alarm unit to sound an alarm to remind the operator to close the circumferential body 1 as soon as possible. In other embodiments, a mute button for turning off the alarm sound is provided on the alarm unit. Specifically, the first temperature sensor 43 and the second temperature sensor 44 are both WZP-PT100.

[0033] Moving assembly 5, the moving assembly 5 is used to move the circumferential body 1, specifically, please refer to Figure 1 and Figure 2 The moving assembly 5 includes a support plate 51 , moving rollers 52 fixed to the four corners of the lower surface of the support plate 51 , and two support frames 53 fixed to the upper surface of the support plate 51 , and the circumferential body 1 is clamped between the two support frames 53 .

[0034] In this specific embodiment, please refer to Figure 3 and Figure 4 The cooling sleeve 31 includes a tube body 311, a connecting tube 312 fixed in the tube body 311, and a sealing cover 313 fixed at one end of the tube body 311. An annular space is formed between the outer wall of the connecting tube 312 and the inner wall of the tube body 311. The outer wall of the tube body 311 is provided with a liquid inlet end 314 and a liquid discharge end 315 connected to the annular space, and the liquid inlet end 314 and the liquid discharge end 315 are arranged obliquely with the axis of the tube body 311, which can reduce the space volume occupied by the cooling sleeve 31, and is also applicable to valves of smaller models. A connecting hole 31a connected to the connecting tube 312 is opened on the sealing cover 313. The X-ray tube 11 is fixedly connected to the inner wall of the connecting tube 312 via the connecting hole 31a. The liquid outlet of the pump body unit 32 is connected to the liquid inlet end 314 via the first connecting hose 33, and the liquid discharge end 315 is connected to the water inlet pipe 21 via the second connecting hose 34.

[0035] On the basis of the above scheme, the moving assembly 5 also includes a locking ring block 54 and a bolt 55. The locking ring block 54 is fixedly connected to the support frame 53 via the bolt 55, so that the locking ring block 54 fixes the circumferential body 1 on the support frame 53. A moving handle 56 is provided on one side of the support plate 51.

[0036] In order to prevent the operator from being unable to hear the alarm sound emitted by the alarm unit 45 in a noisy environment, in this specific embodiment, a warning light unit 46 is also included which is fixedly mounted on the outer wall of the control box body 41, and the warning light unit 46 is electrically connected to the processor 42. Specifically, the flaw detection of the valve is usually carried out in a room with thicker walls and a darker environment. The warning light unit 46 is a flashing warning light, which makes it easier for the operator to detect that the heating temperature of the circumferential body 1 is too high.

[0037] During use, the circumferential body 1 is moved to different positions by pushing the moving handle 56 to detect multiple valves (not shown in the figure). The X-ray tube 11 on the circumferential body 1 is extended to the inside of a valve connection, the circumferential body 1 is opened, and the X-rays penetrate the valve, so that images with different blackness are formed on the photosensitive film fixed on the outer wall of the valve connection end, thereby completing the detection of the valve. During the measurement process, the cooling liquid 23 in the water tank 2 is introduced into the annular space through the pump body unit 32 to cool the anode target 12, so as to avoid the anode target 12 in the X-ray tube 11 from being damaged due to excessive temperature. The temperature difference of the cooling liquid 23 between the water inlet pipe 21 and the water outlet pipe 22 is detected by the first temperature sensor 43 and the second temperature sensor 44. If the temperature difference exceeds 30°, the processor 42 controls the alarm unit 45 to sound an alarm, and at the same time, controls the warning light unit 46 to flash, reminding the operator to close the circumferential body 1 in time and stop working, so as to avoid the anode target from being damaged due to excessive temperature.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered within the protection scope of the present invention.
