Description

Technical Field

[0001] The present invention relates to the technical field of agitator tank testing, and particularly to a testing device facilitating the detection of the outer surface of an agitator tank. Background Art

[0002] Agitator tanks are widely used in industries such as coatings, chemicals, pigments, and resins, and the market demand is stable. With the continuous development of the coatings industry, the performance and quality requirements for agitator tanks are also constantly increasing, prompting production enterprises to continuously carry out technological innovation and product upgrading. For this reason, a testing device facilitating the detection of the outer surface of an agitator tank is proposed.

[0003] A Chinese patent with the patent publication number CN119354802A discloses a detection device for the inner wall of a special coatings agitator tank. The device can position a paint bucket reaching a specified position through the movement of a positioning mechanism, can scrape and collect the dried and residual paint on the inner wall by using a scraping component, and can conveniently detect small holes on the inner wall of the tank by using a test piece. The device can achieve multi-functional detection on the inner side of the tank, and the function switching is convenient;

[0004] This device can only detect the inner wall of the tank body, and due to the large volume of the tank body, the entire device occupies a large space, and the device is heavy and has a special shape, so it is inconvenient to operate and detect;

[0005] Moreover, the outer surface of the tank body is exposed to the air for a long time and is also easily affected by the environment, resulting in a series of corrosion conditions. Over time, corrosion will produce holes, which may cause the leakage of coatings or chemical solvents, not only polluting the environment but also possibly causing fires;

[0006] During the transportation, production, etc. of the agitator tank, wear or mechanical damage may occur. When there is too much damage, the strength of the tank body will decrease, and weak points will be generated in local areas of the tank body, easily causing the phenomenon of tank body rupture;

[0007] The outer surface of the agitator tank is coated with an anti-corrosion layer, a heat-insulating layer or a fire-proof coating. The damage of these functional coatings will also reduce the protection effect on the tank body. Summary of the Invention

[0060] Working principle: For the convenience of detection, the mixing tank body to be detected is cut into a "U"-shaped tank body sample 3 for easy testing. The tank body sample 3 is horizontally placed on the top surface of the mounting plate 26, and then the two ends of the tank body sample 3 are fixed to the top surface of the mounting plate 26 with screws. Then, the telescopic cylinder 23 is controlled to retract, and the toothed plate 24 moves backward, driving the first gear 25 to rotate at the same time. The mounting plate 26 will turn to a vertical state, and its bottom is supported on the abutting block 211. Then, the adjusting ring 291 is rotated, and the adjusting plate 29 will move closer to the middle frame plate 28. The limiting block 27 will extend out of the adjusting groove 261 and support on the inner side surface of the tank body sample 3;

[0062] One end of the tape roll 512 is wound around the rack bar 514, then around the second pressure roller 516, and the tensioning piece is adjusted backward. Under the action of the spring, the box body 517 will extend forward, and the second pressure roller 516 will press the end of the tape tightly on the outer surface of the tank body sample 3. Then, the tensioning belt 522 is removed. Under the action of the spring, the cutter head 521 will extend forward. The top end of the cutter head 521 is connected to the outer surface of the tank body sample 3. Then, the connecting handle 48 is inserted into the first driving frame 45, and then the driving motor 42 is controlled to start rotating.

The first driving rod 56 drives the first housing 51 and the second housing 52 to move on the first arc-shaped frame 41. During the movement process, the cutter head 521 will continuously contact the outer surface of the tank body sample 3, and scratches will be generated during this period. The second pressure roller 516 will press the tape tightly on the scratched position of the tank body sample 3, and the first pressure roller 515 will press the tape tightly for the second time. When the movement within the specified range is completed, the pressed tape is torn off. By observing the density and size of the adhered coating on it, the adhesion of the outer surface coating of the tank body sample 3 can be judged. After the detection is completed, reverse the above operations to return the equipment to its original position.

[0063] Embodiment 2 of the present invention:

[0064] Refer to Figure 14-16 , on the basis of Embodiment 1, the following technical solutions are further provided:

[0065] On one side of the second rotating plate, a second arc-shaped frame 411 is fixedly installed. The second test piece 6 is movably connected within the second arc-shaped frame 411. The first cylinder 621 is fixed to the front end of the detection frame 62. The detection probe 63 is spring-connected within the first cylinder 621 and acts to keep the detection probe 63 in continuous contact with the outer surface of the tank sample 3. An inductor is installed within the first cylinder 621. On the inner walls of both sides of the detection frame 62, a first support 64 and a second support 68 are symmetrically installed respectively. The front end of the detection probe 63 is connected to the outer surface of the tank sample 3. A first limiting piece 65 is installed at the rear end of the detection probe 63. The first limiting piece 65 is clamped between the first supports 64 and acts to contract the detection probe 63;

[0066] At the rear end of the detection frame 62, a second cylinder 66 is fixed. The impact rod 69 is spring-connected within the second cylinder 66 and acts to push the first limiting piece 65 forward. A second limiting piece is installed at the front end of the impact rod 69, which is clamped between the second supports 68, and its rear end penetrates to the outside of the second cylinder 66. A plurality of second protective rollers 67 are installed on both sides of the detection frame 62. The second protective rollers 67 are limited within the second arc-shaped frame 411. On one side of the detection frame 62, a second driving rod 61 is also connected. The tail end of the second driving rod 61 is connected between the corresponding arc-shaped groove 44 and the second horizontal groove and can move within the corresponding trajectory.

[0067] Working principle: When it is necessary to detect the corrosion area on the outer surface of the tank sample 3, repeat the above operations. Adjust the tank sample 3 to the vertical state and then control the rotation motor 13 to rotate. The rotating frame plate 4 will perform a 180-degree rotation adjustment, and then move to the specified test position again. Then rotate the first limiting piece 65 by 90 degrees so that the top of the detection probe 63 is continuously connected to the outer surface of the tank sample 3. At this time, insert one end of the connecting handle 48 into the second driving frame 47, and then control the driving motor 42 to rotate. The second driving rod 61 will move within the second horizontal groove and the arc-shaped groove 44, and the detection frame 62 will move within the second arc-shaped frame 411. During the movement, when moving to the corrosive area, under the action of the spring, the end of the detection probe 63 will extend into the hole. At this time, the internal inductor will control the driving motor 42 to stop. Then rotate the second limiting piece by 90 degrees. Under the action of the spring, the second limiting piece will impact forward against the first limiting piece 65. At this time, if the hole in the corrosion area is too deep or the inside and outside of the tank are severely corroded, under the action of the impact force, the detection probe 63 will penetrate through the inner and outer tanks at the corresponding position, and then record its position. Then restore the detection probe 63 and the impact rod 69 to test the next area. Finally, distinguish the corrosion degree of the tank sample 3 according to the penetration and the extension of the detection probe 63.

[0068] Embodiment 3:

[0069] Refer toFigure 17-18 , based on Example 2, the following technical solution is also provided:

[0070] Preferably, the thickness measuring assembly 7 includes a shell, a pressing rod 71, a pressing block 74 and a display rod 72. The shell screws are installed on the front side end of the detection frame 62. Outer rods are symmetrically installed on the inner walls on both sides of the shell. The pressing blocks 74 are slidably connected to the outer surface of the outer rods. The shell and the pressing blocks 74 are spring-connected to squeeze the pressing blocks 74 toward the middle. One side of the pressing block 74 is rollingly connected with a ball 73. The ball 73 is connected to the outer surface of the tank sample 3 to reduce the influence of friction. An extrusion cavity is opened in the shell. The pressing rods 71 ​​are connected with springs on both sides of the extrusion cavity. Extrusion liquid 75 is arranged between the pressing rods 71 ​​to observe the difference in thickness according to the liquid level. The display rod 72 is fixedly installed on one side of the shell, and it is connected to the extrusion cavity. The display rod 72 is filled with gas, and the gas is located on one side of the extrusion liquid 75. One end of the pressing block 74 is connected to the outer end of the pressing rod 71. The display rod 72 is provided with a scale and a liquid level sensor.

[0071] Working principle: When it is necessary to test the wall thickness of the tank sample 3, first rotate the adjustment ring 291 to adjust the limit block 27 backward, then move the vertical tank sample 3 to the test position, and then install the shell screw on the detection frame 62, so that the pressing block 74 is connected to the inner and outer sides of the tank sample 3, and the ball 73 will always be connected to the outer surface of the tank sample 3. Repeat the operation to control the movement of the second test piece 6. During the movement, the ball 73 rolls on the outer surface of the tank sample 3. When the ball 73 moves to the area with thinner wall thickness, the pressing block 74 moves toward the middle under the action of the spring. At this time, the pressing rod 71 will be subjected to an extrusion force toward the middle, and the extruded liquid 75 will be subjected to pressure, which will compress the gas, so that the liquid level indication in the display rod 72 will rise, and the scale and liquid level sensor are observed to reflect the thickness change.
