Description
Technical Field
[0001] The utility model relates to the technical field of radiation tube detection equipment, in particular to a radiation tube water pressure testing and hole cleaning integrated machine. Background Art
[0002] A radiant tube is a device used to heat or cool a fluid by transferring energy through radiation. Typically made of metal, radiant tubes are designed to efficiently transfer heat in industrial furnaces, boilers, or heat exchangers. They can improve thermal efficiency, reduce heat loss, and, in some cases, provide more uniform heat distribution. Water pressure testing is a method used to inspect the sealing performance and pressure-bearing capacity of pipes, containers, or other sealed structures. Water is injected into the system and the pressure is gradually increased to observe for leaks or structural damage, ensuring safety and reliability in actual use. In practice, a radiant tube is usually sealed at one end and water is injected from the other end. The tube is then observed for leaks, or the tube is placed in water and observed for bubbles. Inspecting one radiant tube at a time is inefficient.
[0003] A search revealed an existing patent (publication number: CN118090064B) that discloses a "leak testing device for silicon carbide shell-and-tube heat exchangers, relating to the field of leak testing technology, comprising: a test water tank, with conversion fixing plates fixedly mounted on the front and rear sides of the test water tank; a conversion fixing groove with an inclined top end formed on the outer wall of the conversion fixing plate; support carrier plates fixedly mounted on the left and right sides of the test water tank; and a push inclined plate with an inclined top end fixedly mounted on the inner side of the support carrier plate. This invention automatically performs positioning and sealing tasks during the submersion test of a single tube to be tested, directly omitting two steps in conventional devices, thereby improving the device's ease of use and indirectly enhancing testing efficiency and the production efficiency of silicon carbide shell-and-tube heat exchangers. It solves the conventional problem of first securing the silicon carbide tube, then sealing the end face of the tube to be tested, and finally submerging the tube in water and injecting air for leak testing."
[0004] During the development of this application, the inventors discovered the following problems with the prior art: While the aforementioned comparative patent provides a leak test device for silicon carbide shell-and-tube heat exchangers by assembling a test water tank, a conversion plate, a conversion groove, and a support plate, only a single tube can be inserted at a time, and air injection is required to check for leaks, which somewhat reduces detection efficiency. Therefore, those skilled in the art have provided an all-in-one radiant tube water pressure test and hole cleaning machine to address the problems raised in the aforementioned background art.

DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The present invention provides an embodiment of a radiant tube water pressure test and hole cleaning integrated machine, comprising a base 1, a lifting mechanism 2, eight fixing mechanisms 3, and a plurality of silicon carbide rollers 4. The base 1 comprises a bottom frame 101, and fixing seats 102 are fixedly provided on both sides of the bottom frame 101 near the upper front position. Rotating shaft frames 204 are fixedly provided on the upper ends of the two fixing seats 102. A horizontal frame 202 is fixedly provided at the lower rear end position inside the bottom frame 101, and a cylinder 201 is fixedly provided at the center position of the upper end of the horizontal frame 202.
[0025] The lifting mechanism 2 includes a platform frame 203 and two mounting plates 205. The eight fixing mechanisms 3 each include a mounting seat 304. The lower ends of each group of four mounting seats 304 are evenly fixed to the upper ends of the two mounting plates 205. A plurality of silicon carbide rollers 4 are respectively clamped and set between the eight fixing mechanisms 3 and the platform frame 203.
[0026] Specifically, the base 1 provides a good installation position for the lifting mechanism 2 and the eight fixing mechanisms 3 through the bottom frame 101. The lifting mechanism 2 lifts the platform frame 203 and one end of the multiple silicon carbide rollers 4 on it that are well clamped and installed by the eight fixing mechanisms 3 to an appropriate height through the cylinder 201.
[0027] Reference Figure 1 and Figure 3 : Support seats 103 are fixedly provided on both sides of the upper end of the bottom frame 101, located just above the cross frame 202. Buffer pads 104 are fixedly provided on the upper ends of the two support seats 103. Universal wheels 105 are fixedly provided at the four corners of the lower end of the bottom frame 101.
[0028] Specifically, the two support seats 103 and the two buffer pads 104 provide good support for the platform frame 203 and good shock absorption and buffering when it is lowered. The four universal wheels 105 make it easy for users to move the position of the all-in-one machine and materials according to actual needs, and to carry out inspection work conveniently.
[0029] Reference Figure 1 and Figure 2: The upper end of the cylinder 201 is connected to the middle rear position of the lower end of the platform frame 203 by a ball hinge. The front and rear positions on both sides of the lower end of the platform frame 203 are respectively fixed to the upper ends of the two mounting plates 205 near the two sides. The middle positions on both sides of the front one of the two mounting plates 205 are respectively rotated to the inside of the two rotating shaft frames 204 through the rotating shaft. The lower end of the rear one of the two mounting plates 205 is fixed to the rear position of the upper end of the platform frame 203. V-shaped supporting members are respectively fixed to the front and rear positions of the upper end of the platform frame 203 that contact multiple silicon carbide rollers 4;
[0030] Specifically, the cylinder 201 is connected to the middle rear position of the lower end of the platform frame 203 through a ball joint, which can accurately control the lifting and lowering of the platform frame 203 to ensure stability and accuracy during the test. During the lifting and lowering of the platform frame 203, the ball joint can absorb and disperse the impact force, reducing the vibration directly transmitted to the cylinder 201 or other structural components. The two rotating shaft frames 204 provide good support and limiting effects for the rotating shafts on both sides of the front one of the two mounting plates 205. The V-shaped support member makes the pressure applied to the silicon carbide roller rod 4 evenly distributed, avoiding local overload or damage due to load concentration. At the same time, it can adapt to silicon carbide roller rods 4 of different diameters, providing a universal support solution, and also preventing accidental movement of the roller rod, thereby increasing the safety of operation.
[0031] Reference Figure 1 and Figure 4 : The upper centers of the eight mounting seats 304 are rotatably provided with screw rods 302, the lower middle positions of the outer walls of the eight screw rods 302 are fixed with thumbwheels 303, and the eight screw rods 302 are respectively threadedly sleeved with T-shaped pressure blocks 301 near the upper ends;
[0032] Specifically, the coordinated use of the screw rod 302 and the thumbwheel 303 can achieve precise adjustment, allowing the user to adjust the position of each fixing mechanism 3 as needed to accommodate silicon carbide rollers 4 of different sizes. The T-shaped pressure block 301 is threadedly connected to the screw rod 302, which can stably fix the silicon carbide roller 4 to prevent it from displacement or vibration during the test. The position of the fixing mechanism 3 can be easily adjusted by rotating the screw rod 302. The design of the thumbwheel 303 facilitates manual operation, making the adjustment process more convenient and quick.
[0033] Working principle: When in use, according to actual needs, the user can turn the dial 303 to drive the screw rod 302 to rotate, and the T-shaped pressure block 301 threadedly connected to the screw rod 302 will rise accordingly, increasing the distance between the T-shaped pressure block 301 and the upper end of the platform frame 203 to facilitate the placement of the silicon carbide roller rod 4. After the silicon carbide roller rod 4 is placed on the V-shaped support, the dial 303 is turned in the opposite direction to drive the screw rod 302 to rotate in the opposite direction. The T-shaped pressure block 301 threadedly connected to the screw rod 302 will descend and press the silicon carbide roller rod 4. The all-in-one machine can simultaneously fix multiple silicon carbide roller rods 4 for unified testing. After the user temporarily seals one end of multiple silicon carbide roller rods 4, the other end can be connected to the water source connector to observe whether there is any leakage in the rod body;
[0034] Secondly, the user can conveniently use the cylinder 201 to extend upward, so that the platform frame 203 at its upper end rotates with the front one of the two mounting plates 205 as the axis, that is, the height of one end of the platform frame (203) close to the rear one of the two mounting plates 205 is raised, so that the silicon carbide roller rod 4 is tilted at a certain angle, thereby conveniently and comprehensively observing whether there is any position leakage on the rod body;
[0035] In addition, after the water pressure test, the user can maintain or adjust the tilt angle of the all-in-one machine so that the sealed ends of multiple rollers are uniformly aligned with a bucket or other device for collecting test water, and then remove the temporary seal, so that the inside of the rods is fully cleaned under the action of water flow.
[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
