Technical Field

[0001] The utility model relates to the technical field of waste acid recovery pipe detection devices, in particular to a corrosion resistance detection device for waste acid recovery pipes. Background Art

[0002] Waste acid recovery pipe refers to the pipeline system used to collect and transport waste acid during the waste acid treatment process. In order to understand the corrosion resistance of the waste acid recovery pipe, it is generally tested by an ultrasonic thickness gauge. The ultrasonic thickness gauge can detect the thickness of the waste acid recovery pipe, and then compare it with the waste acid recovery pipe shipped from the factory to determine its corrosion resistance.

[0003] After searching, the patent with the announcement number CN206593613U discloses an ultrasonic thickness gauge, and its content records "including a main body (1), a probe (2) and a display screen (11), characterized in that it also includes an over-temperature prompting system for automatically prompting when the temperature of the workpiece to be measured is too high, and the over-temperature prompting system includes..." From the above, it can be seen that the probe of the ultrasonic thickness gauge of the patent needs to move and contact when detecting the thickness of the tube, and will rub against the tube during this process. Long-term friction is prone to wear, and there are certain shortcomings. Utility Model Content

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0023] The following describes some embodiments of the utility model in conjunction with the accompanying drawings to provide a corrosion resistance detection device for a waste acid recovery pipe.

[0024] Embodiment 1:

[0025] Reference Figure 1-6 , which is the first embodiment of the utility model, provides a corrosion resistance detection device for a waste acid recovery pipe, including an ultrasonic thickness gauge 100, a protective component 200 and an elastic component 300.

[0026] Specifically, the ultrasonic thickness gauge 100 includes a housing 101, a cable 104 disposed at the top of the housing 101, a probe 105 disposed on the cable 104, and a limiting hole 1051 opened on the probe 105. The probe 105 can be moved to the outside of the pipe and contact it to detect the thickness of the recovery pipe.

[0027] Specifically, the protective assembly 200 includes a first spring 201 arranged on the probe 105, a protective plate 202 arranged at the front end of the first spring 201, and a limiting rod 203 arranged at the rear side of the protective plate 202. The protective plate 202 is annular and can prevent the probe 105 from contacting the tube. The first spring 201 makes the protective plate 202 movable, which facilitates pressing the probe 105 to contact the tube. The cooperation of the limiting rod 203 and the limiting hole 1051 can restrain the first spring 201 to prevent the first spring 201 and the probe 105 from wearing due to friction.

[0028] Specifically, the elastic component 300 includes a second spring 301 arranged at the rear side of the probe 105 and a fixing seat 302 arranged on the second spring 301. The second spring 301 enables the probe 105 and the protective component 200 to have a certain buffering effect to prevent the probe 105 and the protective component 200 from colliding with the tube and being worn.

[0029] It should be noted that three second springs 301 and three first springs 201 are provided.

[0030] Embodiment 2:

[0031] Reference Figure 1-3, which is the second embodiment of the utility model, which is different from the first embodiment in that: a storage slot 106 is provided on the rear side of the shell 101, and a holder 108 is provided on the inner side of the storage slot 106. A holder 107 and a through-hole 111 are provided on the inner side of the storage slot 106, and a baffle 102 is inserted in the through-hole 111. The baffle 102 can be inserted in the through-hole 111 and engaged with the holder 107 so as to seal the storage slot 106 through the baffle 102. The holder 108 is a plastic product, and a writing pen 109 is engaged with the holder 108. A work note 110 is placed inside the storage slot 106, and the baffle 102 can be pulled out. After being pulled out, the writing pen 109 and the work note 110 in the storage slot 106 can be taken out to record the corrosion resistance of the waste acid recovery pipe.

[0032] Furthermore, a tightening knob 103 is threadedly connected to the top of the housing 101 , and the tightening knob 103 can be rotated to press against the baffle 102 so as to fix the baffle 102 .

[0033] The working principle and use process of the utility model are as follows: when in use, the fixing seat 302 of the elastic component 300 can be pinched, and the probe 105 and the protective component 200 can be moved through the fixing seat 302 after pinching. After moving to a suitable position, the protective plate 202 of the protective component 200 is brought into contact with the pipe, and the probe 105 is pressed through the fixing seat 302 until the probe 105 is in contact with the pipe. After the contact, the thickness of the pipe can be detected to understand the corrosion resistance of the recovery pipe. During the detection process, the protective plate 202 can prevent the probe 105 from contacting the pipe, and the protective plate 202 can prevent the probe 105 from contacting the pipe through the first spring 201. The plate 202 is movable, which makes it convenient to press the probe 105 into contact with the tube. The process reduces the friction between the probe 105 and the tube and prolongs the service life of the probe 105. Then the second spring 301 of the elastic component 300 makes the probe 105 and the protective component 200 have a certain buffering effect to prevent the probe 105 and the protective component 200 from colliding with the tube and being worn. Thereafter, the tightening knob 103 can be loosened, and the baffle 102 can be pulled out after loosening. After pulling out, the writing pen 109 and work notes 110 in the storage tank 106 can be taken out to record the corrosion resistance of the waste acid recovery tube.

[0034] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
