[0038] In one embodiment, see Figures 1 to 3 As shown, the present invention provides a low-magnification pickling test system, comprising:

[0039] A test box 3, having an acid storage tank 1 and a test tank 2 with an open structure;

[0040] The acid storage cover plate 31 is disposed at the open portion of the acid storage tank 1 by means of a rotating shaft and is used to seal the acid storage tank 1;

[0041] The acid storage telescopic cylinder 32 has one end connected to the test box 3 by means of a rotating shaft, and the other end connected to the acid storage cover plate 31 by means of a rotating shaft;

[0044] The conveying module is connected to the acid storage tank 1 at one end and to the test tank 2 at the other end, and is used to control the flow of the pickling solution between the acid storage tank 1 and the test tank 2.

[0045] Specifically, the acid storage tank 1 has a first liquid inlet pipe, a first liquid outlet pipe and an acid storage exhaust port, the acid storage exhaust port is connected to an external waste gas treatment device by negative pressure, and the treatment device can neutralize harmful acidic gases; the test tank 2 has a second liquid inlet pipe, a second liquid outlet pipe and a test exhaust port, the test exhaust port is connected to an external treatment device by negative pressure, and the treatment device can neutralize harmful acidic gases; the conveying module includes an acid adding pump and a liquid return pump, the liquid inlet of the acid adding pump is connected to the first liquid outlet pipe, the liquid outlet of the acid adding pump is connected to the second liquid inlet pipe, the liquid inlet of the liquid return pump is connected to the second liquid outlet pipe, and the liquid outlet of the liquid return pump is connected to the first liquid inlet pipe.

[0046] In summary, the present invention stores the pickling solution in a sealed acid storage tank 1, which can effectively isolate the volatilization of the pickling solution, avoid air pollution caused by the volatiles of the acidic liquid, and protect the test personnel. At the same time, the test sample is immersed in the test using the test tank 2, so that the acidic liquid can flow between the acid storage tank 1 and the test tank 2, thereby reducing the volatiles of the acidic liquid and further improving the safety of the testing environment.

[0047] In an optional example, the low-magnification pickling test system also includes a three-way diverter valve, one end of the three-way diverter valve is connected to the liquid inlet of the return liquid pump, the other end of the three-way diverter valve is connected to the second liquid outlet pipe, and the last end of the three-way diverter valve is connected to an external liquid supply device, which is used to provide pickling liquid.

[0048] In an alternative example, see Figures 1 to 4 As shown, since the test pool 2 has a long depth, in order to facilitate the operator to take and place the test sample, the low-magnification pickling test system also includes a guide module, which includes a guide bracket 41 fixed in the test pool 2 by bolts, and the guide bracket 41 has a sliding channel arranged vertically, and a test platform 42 for supporting the test sample is installed in the sliding channel by sliding, and the test platform 42 is provided with a lifting lug 421. Among them, the lifting lug 421 can be connected to an external lifting device, and the lifting device raises the height of the test platform 42 through the lifting lug 421.

[0049] Specifically, this example adds a guide module to cooperate with an external lifting device to move the test sample vertically, which can effectively reduce the labor intensity of operators in moving the test samples and facilitate operators to take and place the test samples.

[0050] In an alternative example, see Figures 1 to 5 As shown, in order to facilitate the disassembly and assembly of the low-magnification pickling test system, the guide bracket 41 is set in a rectangular shape, and the guide bracket 41 includes four vertical pillars 411, four width brackets 412 and two oblique brackets 413. The four vertical pillars 411 are respectively set at four vertices, the width bracket 412 is connected to the two vertical pillars 411 in the width direction by bolts, and the oblique bracket 413 is connected to the two vertical pillars 411 in the length direction by bolts. A guide wheel 414 is installed on the test platform 42 through a bearing, and a limit bar 4111 for guiding the guide wheel 414 is set on the vertical pillar 411 along the length direction. The four limit bars 4111 are combined to form a sliding channel. Among them, the vertical pillar 411 is connected to the bottom of the test pool 2 by bolts.

[0051] Specifically, this example can effectively reduce the difficulty of manufacturing the guide bracket 41 by configuring the guide bracket 41 to be three parts, facilitate the disassembly and assembly of the low-magnification pickling test system, and reduce the manufacturing cost of the low-magnification pickling test system.

[0052] In an alternative example, see Figures 1 to 4 As shown, in order to further reduce the pollution of the volatiles of the acidic liquid to the air, the low-magnification pickling test system also includes a cleaning module arranged on the top of the test pool 2, and the cleaning module includes a cleaning bracket 51 connected to the test cover plate 33, and a plurality of groups of cleaning units 1 52 are installed at the lower end of the cleaning bracket 51, and the cleaning unit 1 52 has a cleaning flow channel 1 connected to the outside of the test pool 2. Among them, the cleaning flow channel 1 is connected to an external liquid supply device, and the liquid supply device is used to provide a cleaning liquid for cleaning the test sample, and the cleaning liquid can be an alkaline liquid or a neutral liquid.

[0053] The cleaning module also includes a plurality of cleaning units 2 53 connected to the vertical support 411. The cleaning unit 2 53 has a cleaning flow channel 2. The guide bracket 41 has a guide flow channel 54 connected to the outside of the test tank 2. The guide flow channel 54 is connected to the cleaning flow channel 2. The cleaning flow channel 2 is connected to an external liquid supply device, and the liquid supply device is used to provide a cleaning liquid for cleaning the test sample. The cleaning liquid can be an alkaline liquid and a neutral liquid. The alkaline liquid can be neutralized with the acidic liquid. The neutral liquid can clean the surface of the test sample to avoid the residue of harmful substances.

[0054] Specifically, this example realizes the cleaning of the test sample in the test pool 2 by adding cleaning unit 1 52 and cleaning unit 2 53, which can effectively neutralize the acidic solution and avoid the operator's operation steps of taking out the test sample for cleaning, further reducing the volatilization of the acidic liquid to the air and improving the safety of the low-multiple acid cleaning test system.

[0055] In an alternative example, see Figures 1 to 8 As shown, the cleaning unit 52 includes a cleaning base 521, in which a cleaning shaft 522 is rotatably mounted, the lower end of the cleaning shaft 522 penetrates the lower end of the cleaning base 521, and a spray rack 523 is fixed, a spray channel 1 5231 penetrating the spray rack 523 is provided in the spray rack 523, a spray channel 2 5221 is provided on the cleaning shaft 522 along the center line direction, a spray channel 3 5211 is provided in the cleaning base 521, the spray channel 1 5231, the spray channel 2 5221 and the spray channel 3 5211 are connected to each other, and are combined to form a cleaning flow channel 1. Among them, the spray rack 523 includes a main body 52301 and a plurality of guide parts 52302 arranged toward a direction away from the rotation center of the cleaning shaft 522. The main body 52301 is connected to the cleaning shaft 522 by bolts. The spray channel 1 5231 includes a main section 52311 and a plurality of split sections 52312. The main section 52311 is opened in the main body 52301. The liquid inlet of the main section 52311 is connected to the spray channel 2 5221. A split section 52312 is opened in a guide part 52302. The liquid inlet of the split section 52312 is connected to the liquid outlet of the main section 52311. The liquid outlet of the split section 52312 is away from the rotation center of the cleaning shaft 522 and is arranged toward obliquely downward. The liquid outlet of the split section 52312 may be one or more.

[0056] Specifically, in this example, the cleaning liquid can be sprayed out from spray channel one 5231 through the diversion of spray channel one 5231, spray channel two 5221 and spray channel three 5211. Since the liquid outlet of spray channel one 5231 is away from the rotation center direction of the cleaning shaft 522, the spray frame 523 is driven to rotate by centrifugal force when the cleaning liquid is sprayed, thereby improving the spraying uniformity of the cleaning liquid, reducing the residue of acidic liquid, and avoiding pollution to the test environment.

[0057] As an example, see Figures 1 to 8 As shown, a limiting flange 524 is fixed to the upper end of the cleaning shaft 522 by bolt connection, and a flow chamber 5212 is also provided in the spray channel 3 5211, and a flow bearing 525 is inserted and fixed in the flow chamber 5212. The cleaning shaft 522 is inserted and fixed to the inner ring of the flow bearing 525 by interference fit. The limiting flange 524 is arranged in the flow chamber 5212, and a spray channel 4 5241 penetrating the limiting flange 524 is provided on the limiting flange 524. One end of the spray channel 4 5241 is connected to the spray channel 2 5221, and the other end of the spray channel 4 5241 is connected to the flow chamber 5212. Among them, the spray channel 4 5241 has a liquid outlet and multiple liquid inlet ends, the liquid inlet end is provided on the outer wall of the limiting flange 524 and is provided in the flow chamber 5212, and the liquid outlet end is provided at one end facing the cleaning shaft 522 in a direction away from the cleaning base 1 521.

[0058] Specifically, this example adopts a multi-liquid inlet end design, which optimizes the flow path of the cleaning liquid and ensures the flow speed of the cleaning liquid. When the cleaning liquid is sprayed out from the spray channel 5231, it can push the spray frame 523 to rotate with the cleaning axis 522, thereby increasing the scattering area of ​​the cleaning liquid, reducing the residue of the acidic liquid, and avoiding pollution to the test environment.

[0059] As an example, see Figures 1 to 8 As shown, the cleaning base 521 includes a base body 1 5213 and a base body 2 5214 which are interconnected by bolts. The base body 1 5213 is connected to the cleaning bracket 51 by bolts. A first groove is formed at one end of the base body 1 5213 facing the base body 2 5214, and a second groove is formed at one end of the base body 2 5214 facing the base body 1 5213. The first groove and the second groove are combined to form a flow chamber 5212.

[0060] Specifically, this example facilitates the processing of the cleaning base 1 521 and reduces the manufacturing and maintenance costs of the cleaning base 1 521 by splitting the cleaning base 1 521 into a base body 1 5213 and a base body 2 5214 .

[0061] In an alternative example, see Figures 1 to 10As shown, the cleaning unit 2 53 includes a cleaning base 2 531 and an adjusting head 532. The cleaning base 2 531 includes a curved tube portion 5311 and connecting portions 5312 and a ball head portion 5313 arranged at both ends of the curved tube portion 5311. The adjusting head 532 is mounted on the outer wall of the ball head portion 5313 by rotation. The adjusting head 532 has a spray port 533. The cleaning base 2 531 has a nozzle channel 1 5314 that passes through the curved tube portion 5311, the connecting portion 5312 and the ball head portion 5313. The adjusting head 532 has a nozzle channel 2 5321 that passes through the adjusting head 532. The nozzle channel 1 5314, the nozzle channel 2 5321 and the ball head portion 5313 are interconnected and combined to form a cleaning flow channel 2. Among them, a ball head groove matching the shape of the ball head 5313 is opened on the adjusting head 532. The adjusting head 532 can rotate around the outer circle of the ball head 5313 through the cooperation between the ball head groove and the ball head 5313; the connecting part 5312 is connected to the vertical pillar 411 by a threaded connection.

[0062] Specifically, this example controls the spray angle of the spray port 533 through the cooperation of the curved pipe portion 5311, the ball head portion 5313 and the adjusting head 532, so that the cleaning liquid can be fully sprayed onto the surface of the test sample, thereby ensuring the cleaning effect of the test sample, reducing the residue of the acidic liquid, and avoiding pollution to the test environment.

[0063] In an alternative example, see Figures 1 to 12 As shown, the low-magnification pickling test system also includes two support mechanisms 6 symmetrically arranged on the upper part of the guide bracket 41, and the support mechanism 6 includes a driving component and two support components. The driving component has two driving ends, and the support component has a support end that moves toward the test platform 42. One driving end matches a support component and is used to drive the support end to move toward or away from the test platform 42. When the test platform 42 moves to a set height, the operator controls the driving component to work, and the driving end of the driving component drives the two support components to work, and the support component controls the support end to move until it moves to a set position to support the bottom of the test platform 42.

[0064] Specifically, in this example, the test platform 42 is supported by the driving support end of the support mechanism 6, which can effectively increase the stability of the test platform 42, facilitate the taking of test materials, and improve the safety of the low-magnification pickling test system when in use.

[0065] In an alternative example, see Figures 1 to 13As shown, the driving assembly includes a driving bracket 61, which is fixedly connected to the guide bracket 41. A driving shaft 62 is inserted into the driving bracket 61 in a rotating manner. A driving wheel 63 and an active arm 64 are fixed to the outer wall of the driving shaft 62 in a key connection manner. The driving bracket 61 is provided with a locking rod 65 in a sliding manner. A locking protrusion 651 is provided at one end of the locking rod 65 facing the driving wheel 63. A locking groove 631 matching the locking protrusion 651 is provided on the driving wheel 63. A locking spring 66 is mounted on the outer wall of the locking rod 65. One end of the locking spring 66 conflicts with the driving bracket 61, and the other end of the locking spring 66 conflicts with the locking protrusion 651, and drives the locking protrusion 651 to move in the direction of the locking groove 631. The driving end includes a driving arm 67. One end of the driving arm 67 is connected to the active arm 64 by a rotating shaft connection, and the other end of the driving arm 67 is connected to the support assembly power by a rotating shaft connection. The driving bracket 61 is provided with a sliding hole, the locking rod 65 is slidably inserted in the sliding hole, and the rotation direction of the driving arm shaft is parallel to the rotation direction of the driving shaft 62 .

[0066] Specifically, when the operator rotates the driving wheel 63, the driving wheel 63 drives the driving shaft 62 to rotate, the driving shaft 62 drives the active arm 64 to move, the active arm 64 drives the driving arm 67 to move, and the driving arm 67 drives the supporting assembly to work, thereby realizing the power connection of the supporting assembly. At the same time, when the driving wheel 63 rotates to the set position, the elastic force of the locking spring 66 pushes the locking protrusion 651 to move, and the locking protrusion 651 drives the locking rod 65 to move until the locking protrusion 651 is inserted into the locking groove 631, thereby fixing the driving wheel 63 and the driving arm 67, thereby realizing the position locking of the support assembly.

[0067] In an alternative example, see Figures 1 to 13As shown, the support assembly includes a support frame 68, which is fixedly connected to the guide bracket 41 by bolts, a sliding rack 69 is installed on the support frame 68 in a sliding manner, the other end of the driving arm 67 is meshed with the sliding rack 69 by a rotating shaft connection, a driven gear 610 is installed on the support frame 68 in a rotating manner, the driven gear 610 is meshed with the sliding rack 69, and the support end includes a support slider 611, the support slider 611 is installed on the end of the support frame 68 toward the guide bracket 41 in a sliding manner, and a driven screw 612 is installed on the end of the support slider 611 toward the guide bracket 41 by a rotating manner, and the driven screw 612 is driven and connected to the inner ring of the driven gear 610 by a threaded connection. Among them, a sliding groove is opened on the support frame 68, and the sliding rack 69 is slidably inserted in the sliding groove.
