Description

Technical Field

[0001] This utility model relates to the field of corrosion tank technology, and in particular to an inner wall structure of a corrosion tank that is periodically immersed in a test solution. Background Technology

[0002] A periodic immersion corrosion tank is a test device used to simulate the long-term exposure of materials to specific corrosive environments. Its core feature is that it accelerates the evaluation of the corrosion resistance of materials or coatings through a cyclic process of periodic immersion and drying.

[0003] When the inner shell of the existing corrosion tank is damaged, it is mostly necessary to rely on manual operation to install and disassemble the inner shell. Manual operation requires aligning, tightening or disassembling multiple parts step by step. The whole process is cumbersome and time-consuming, which leads to an extension of the test preparation time. Utility Model Content

[0004] The purpose of this invention is to provide a structure for the inner wall of a periodically immersing test solution corrosion tank. This structure facilitates the replacement and installation of the inner shell, thus solving the problem of easy replacement and installation of the inner shell in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A structure for the inner wall of a periodic immersion test solution corrosion tank includes a shell, a cooling pipe fixedly connected inside the shell, two grooves provided in the shell, an electromagnet fixedly connected inside the lower end of each groove, an electric actuator fixedly connected inside the lower end of the shell, a plate slidably connected to the bottom of the shell, the lower end of the plate being fixedly connected to the output end of the electric actuator; and an inner shell slidably disposed inside the shell, the sidewall of the inner shell fitting against the sidewall of the cooling pipe, the lower end of the inner shell fitting against the upper end of the plate, protrusions fixedly connected to both sides of the inner shell, the protrusions slidably connected to the grooves, and an iron block fixedly connected inside the lower end of the protrusion, the iron block cooperating with the electromagnet.

[0007] Preferably, the inner wall of the housing is provided with an annular groove, and the cooling pipe is located inside the annular groove.

[0008] Preferably, a housing is fixedly connected to the side wall of the housing, a pump body is fixedly connected inside the housing, and a top cover is fixedly connected to the upper end of the housing by bolts.

[0009] Preferably, both ends of the cooling pipe are connected to the inside of the housing, and the output end of the pump body is connected to one end of the cooling pipe.

[0010] Preferably, a semiconductor cooler is fixedly connected through the side wall of the housing, and the cooling end of the semiconductor cooler is located inside the housing.

[0011] Preferably, a plurality of bottom columns are fixedly connected to the lower end of the housing, and the plurality of bottom columns are distributed in a rectangular array.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. When the inner wall of the inner shell is damaged, simply turn off the power to the electromagnet and push the plate upward with the electric push rod to remove the inner shell from the shell. This makes it easy to replace the inner shell in time. Then, pull the plate with the electric push rod to make the inner shell slide into the shell automatically. The electromagnet and the iron block are used to quickly fix it in place, which simplifies the installation process and improves the efficiency of operation.

[0014] 2. When the coolant flows inside the cooling pipe, it quickly absorbs the heat from the inner shell and the corrosive solution inside through heat exchange, and carries the heat out of the shell for heat dissipation, effectively reducing the temperature of the test environment. By circulating the coolant and continuously exchanging heat, the cooling system can maintain the temperature of the inner shell and the corrosive solution inside, avoiding adverse effects on the test results due to temperature fluctuations.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A structure for the inner wall of a periodically immersing test solution corrosion tank includes a shell 001, a cooling pipe 102 fixedly connected inside the shell 001, two grooves 106 provided in the shell 001, an electromagnet 107 fixedly connected inside the lower end of the grooves 106, an electric actuator 108 fixedly connected inside the lower end of the shell 001, a plate 109 slidably connected to the bottom of the shell 001, and the lower end of the plate 109 fixedly connected to the output end of the electric actuator 108; and an inner shell 002 slidably disposed inside the shell 001, with its sidewall connected to the cooling pipe 102. 2. Side walls are fitted together. The lower end of the inner shell 002 is fitted with the upper end of the plate 109. Both sides of the inner shell 002 are fixedly connected to protrusions 201, which are slidably connected to grooves 106. An iron block 202 is fixedly connected inside the lower end of each protrusion 201, and the iron block 202 cooperates with an electromagnet 107. The operator places the inner shell 002 on top of the plate 109, positioning the protrusions 201 above the grooves 106. Then, the output end of the electric actuator 108 pulls the plate 109 downwards, causing the inner shell 002 to slide into the shell 001. The lower end of the plate 109 then fits into the shell. When the bottom of body 001 contacts the inner shell, the electric actuator 108 stops operating. At this time, the inner shell 002 slides into the interior of body 001, and the side wall of the inner shell 002 comes into contact with the side wall of the cooling pipe 102. Simultaneously, the protrusion 201 slides into the groove 106. Then, the operator energizes the electromagnet 107, which generates a magnetic force to attract the iron block 202. Through the cooperation between the electromagnet 107 and the iron block 202, the protrusion 201 is fixed inside the groove 106, thereby fixing the inner shell 002 inside body 001. After the inner shell 002 is fixed, the operator... The operator places the test material inside the inner shell 002. Then, the operator slowly and evenly introduces the pre-prepared corrosion solution into the inner shell 002 through the corrosion solution delivery system until the solution completely covers the surface of the test material. The test material is subjected to a periodic immersion corrosion test by the corrosion solution. When the corrosion solution reacts with the test material and generates heat, coolant flows inside the cooling pipe 102. Through heat exchange, the coolant absorbs the heat from the inner shell 002 and the corrosion solution inside, and carries the heat out of the shell 001 for heat dissipation.

[0023] The inner wall of the housing 001 is provided with an annular groove 101, and the cooling pipe 102 is located inside the annular groove 101. The annular groove 101 is used to accommodate the cooling pipe 102.

[0024] A housing 103 is fixedly connected to the side wall of the casing 001. A pump 104 is fixedly connected inside the housing 103. A top cover 105 is fixedly connected to the top of the housing 103 by bolts. Coolant is stored inside the housing 103. The pump 104 draws the coolant from the housing 103. When coolant needs to be added to the housing 103, the operator removes the connecting bolts between the top cover 105 and the housing 103, then removes the top cover 105 to expose the port at the top of the housing 103, and then adds coolant to the housing 103.

[0025] Both ends of the cooling pipe 102 are connected to the inside of the housing 103. The output end of the pump body 104 is connected to one end of the cooling pipe 102. The pump body 104 delivers coolant from one end of the cooling pipe 102 to the inside of the cooling pipe 102. Then, the coolant that has undergone heat exchange flows back to the inside of the housing 103 from the other end of the cooling pipe 102.

[0026] A semiconductor cooler is fixedly connected through the side wall of the housing 103. The cooling end of the semiconductor cooler is located inside the housing 103. The semiconductor cooler cools the coolant inside the housing 103. The pump 104, electromagnet 107, electric actuator 108 and semiconductor cooler are all manually operated by the operator.

[0027] Multiple base columns 110 are fixedly connected to the lower end of the housing 001. The multiple base columns 110 are distributed in a rectangular array and support the housing 001 through the multiple base columns 110.

[0028] In this invention, the operator places the inner shell 002 on the upper end of the plate 109, so that the protrusion 201 is located above the groove 106. Then, the output end of the electric push rod 108 pulls the plate 109 downward, causing the inner shell 002 to slide into the shell 001. The lower end of the plate 109 contacts the bottom of the shell 001, and the electric push rod 108 stops operating. At this time, the inner shell 002 slides into the shell 001, and the side wall of the inner shell 002 is in contact with the side wall of the cooling pipe 102. At the same time, the protrusion 201 slides into the groove 106. Then, the operator energizes the electromagnet 107, and the electromagnet 107 generates magnetic force to attract the iron block 202. Through the cooperation between the electromagnet 107 and the iron block 202, the protrusion 201 is fixed inside the groove 106, thereby fixing the inner shell 002 inside the shell 001.

[0029] After the inner shell 002 is fixed, the operator places the test material inside the inner shell 002. Then, the operator slowly and evenly introduces the pre-prepared corrosion solution into the inner shell 002 through the corrosion solution delivery system until the solution completely covers the surface of the test material. The test material is then subjected to a periodic immersion corrosion test using the corrosion solution.

[0030] When the operator observes that the corrosive solution reacts with the test material and generates heat, the semiconductor cooler operates to cool the coolant inside the chamber 103. After the coolant is cooled to a suitable temperature, the pump 104 draws the coolant from inside the chamber 103. Then, the pump 104 delivers the coolant from one end of the cooling pipe 102 to the inside of the cooling pipe 102. Through heat exchange, the coolant absorbs the heat from the inner shell 002 and the corrosive solution inside, and carries the heat out of the shell 001 for heat dissipation. The heat-exchanged coolant flows back to the inside of the chamber 103 from the other end of the cooling pipe 102, and is then cooled by the semiconductor cooler.

[0031] When the inner wall of the inner shell 002 is damaged and needs to be replaced, the operator extracts the corrosive solution inside the inner shell 002, then the electromagnet 107 is de-energized, and then the output end of the electric push rod 108 pushes the plate 109 to slide upward, so that the inner shell 002 slides out of the outer shell 001. At the same time, the protrusion 201 slides out of the groove 106 until the upper end of the plate 109 is level with the upper end of the outer shell 001, and then the operator can replace the inner shell 002.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
