Description

Technical Field

[0001] The invention relates to the technical field of stirring tank testing, and in particular to a testing device for facilitating detection of the outer surface of a stirring tank. Background Art

[0002] Mixing tanks are widely used in coatings, chemicals, pigments, resins and other industries, and the market demand is stable. With the continuous development of the coatings industry, the performance and quality requirements of mixing tanks are also constantly improving, prompting manufacturers to continuously carry out technological innovation and product upgrades. For this reason, a test device that is convenient for testing the outer surface of the mixing tank is proposed.

[0003] The Chinese patent with patent announcement number CN119354802A discloses a detection device for the inner wall of a special paint mixing tank. The device can position the paint bucket that has reached the specified position by moving the positioning mechanism, and can scrape and collect the dried and residual paint on the inner wall by using the scraping component. The test piece can conveniently detect the small holes on the inner wall of the tank. The device can realize multi-functional detection of the inner side of the tank, and the function switching is convenient; The device can only detect the inner wall of the tank, and due to the large size of the tank, the entire device occupies a large space, and the device is bulky and has a special shape, so it is inconvenient to operate and detect; Moreover, the outer surface of the tank is exposed to the air for a long time and is easily affected by the environment, resulting in a series of corrosion conditions. Over time, corrosion will produce holes, which may lead to the leakage of paint or chemical solvents, which will not only pollute the environment but also cause fires. The mixing tank may be worn or mechanically damaged during transportation and production. When the damage is too much, the strength of the tank will decrease, and weak points will appear in local areas of the tank, which may easily cause the tank to rupture. The outer surface of the mixing tank is coated with an anti-corrosion layer, a heat-insulating layer or a fire-retardant coating. Damage to these functional coatings will also reduce the protective effect of the tank body. Summary of the invention

[0024] Working principle: In order to facilitate the detection, the mixing tank to be detected is cut into a "U"-shaped tank sample 3 for testing. The tank sample 3 is placed horizontally on the top surface of the mounting plate 26, and then the two ends of the tank sample 3 are screwed to the top surface of the mounting plate 26. Then the telescopic cylinder 23 is controlled to retract, and the tooth plate 24 moves backward, while driving the first gear 25 to rotate. The mounting plate 26 will flip to a vertical state, and its bottom is supported on the abutment block 211. Then the adjusting ring 291 is rotated, and the adjusting plate 29 will approach the middle frame plate 28, and the limit block 27 will extend from the adjusting slot 261 and support the inner side of the tank sample 3. When the outer surface coating adhesion test of the can body sample 3 is required, the conveying motor 12 is controlled to start rotating, and the can body sample 3 in the vertical state is moved between the first arc-shaped frames 41; One end of the tape roll 512 is passed around the frame rod 514, and then around the second pressure roller 516, and the elastic sheet is adjusted backward.

The second pressing roller 516 will press the tape on the scratch position of the tank sample 3, and the first pressing roller 515 will press the tape for the second time. After completing the movement within the specified range, the pressed tape will be torn off, and the density and size of the coating stuck on it can be observed to determine the coating adhesion on the outer surface of the tank sample 3. After completing the inspection, the above operation can be reversed to return the equipment to its original position.

A plurality of second protective rollers 67 are installed on both sides of the detection frame 62, and the second protective rollers 67 are limited in the second arc frame 411. A second driving rod 61 is also connected to one side of the detection frame 62, and the tail end of the second driving rod 61 is connected between the corresponding arc groove 44 and the second horizontal groove, and can move in the corresponding trajectory.

[0026] Working principle: when it is necessary to detect the corrosion area on the outer surface of the tank sample 3, repeat the above operation, adjust the tank sample 3 to a vertical state and then control the rotating motor 13 to rotate, the rotating frame 4 will be rotated 180 degrees, and then move to the specified test position again, and then rotate the first limit plate 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, and then 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 in the second horizontal groove and the arc groove 44, and the detection frame 62 will move in the second arc frame 411, and the movement process During the process, when it moves to the corrosive area, the end of the detection probe 63 will extend into the hole under the action of the spring. At this time, the internal sensor will control the drive motor 42 to stop, and then rotate the second limit plate ninety degrees. Under the action of the spring, the second limit plate will impact forward and hit the first limit plate 65. At this time, if the hole in the corrosive area is too deep or the corrosion inside and outside the tank body is serious, under the action of the impact force, the detection probe 63 will open up the inner and outer tank bodies at the corresponding position, and then record its position, and then restore the detection probe 63 and the impact rod 69 to test the next area. Finally, the degree of corrosion of the tank sample 3 is identified according to the opening and extension of the detection probe 63.

[0027] This embodiment 3: Reference Figure 17-18 , based on Example 2, the following technical solution is also provided: 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.

[0028] 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.
