[0002] Partition is a kind of building material commonly used in daily construction. It is easy to build and easy to remove, can effectively divide indoor space, and has good sound insulation effect, so it is widely used in most public and office buildings. Partition keel is a main supporting component of partition, so it has strict requirements on its hardness, sound insulation, flame retardant and heat insulation performance. At present, many schools, factories and public research institutions also use partitions to divide into individual laboratories. However, during chemical experiments, chemical solvents are often volatilized, chemical reactions often occur and splash, and chemical reagents may splash onto the partition keel due to operation errors. Therefore, the chemical reagent corrosion resistance of the partition keel material for building chemical laboratories needs to be higher than that of ordinary partition keels. If the chemical reagent corrosion resistance of the partition keel material for building chemical laboratories is insufficient, accidents may occur.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the protection scope of the present application.

[0021] A kind of partition drossel material performance detection device, including detection box 1, the detection 1 front side of box door 2 is provided, the box door 2 is provided with observation window 3 and handle 4, the rear side of the detection box 1 is provided with motor 5 in, the output shaft of the motor 5 is fixedly connected with the rear end middle part of partition drossel material fixed structure, the both sides of the detection box 1 are each provided with one vertical pipe 6, the vertical pipe 6 is provided with several solution sprayers 7 towards partition drossel material fixed structure, the side of one vertical pipe 6 away from partition drossel material fixed structure is connected with mixed solvent tank 8 in by pipeline, the solvent in mixed solvent tank 8 includes methanol, ethanol, ethyl acetate, petroleum ether, DMF, formaldehyde, toluene etc. The mixed solvent of common solvent in laboratory, the side of another vertical pipe 6 away from partition drossel material fixed structure is connected with concentrated sulfuric acid tank 9 and aqua regia tank 10 in by pipeline, the connecting pipeline of one vertical pipe 6 and mixed solvent tank 8 is provided with solvent pump 11, the connecting pipeline of another vertical pipe 6 and concentrated sulfuric acid tank 9 and aqua regia tank 10 is each provided with one acid pump 12, the top and bottom of the detection box 1 is each provided with one multistage hydraulic cylinder 13, the end of multistage hydraulic cylinder 13 close to partition drossel material fixed structure is provided with pressing plate 14, the detection box 1 is provided with heating plate 15.The application uses the partitioning of the material to be detected by the partitioning of the material fixing structure, then the box door 2 is closed, the motor 5 drives the partitioning of the material fixing structure to rotate, thereby driving the fixed partitioning of the material to be detected to rotate to the vertical state, then the solvent pump 11 is opened to spray the solvent in the mixed solvent tank 8 to the partitioning of the material to be detected through the corresponding communication stand pipe 6 and the solution spray head 7, while spraying for a certain period of time, the motor 5 drives the partitioning of the material fixing structure to rotate and the fixed partitioning of the material to be detected to rotate 180 degrees, thereby spraying the mixed solvent on the other side, after spraying, the partitioning of the material to be detected is placed for a period of time, and the state of the partitioning of the material after the solvent spraying is simulated. Since a large amount of mixed solvent is sprayed, the amount is greatly increased compared with the actual use, and if the partitioning of the material can resist the corrosion of such a large amount of mixed solvent, the performance in actual use can also be guaranteed. After the partitioning of the material to be detected is placed, the motor 5 drives the partitioning of the material fixing structure to rotate and the fixed partitioning of the material to be detected to rotate to the horizontal position, the two multi-stage hydraulic cylinders 13 are simultaneously elongated, driving the two pressure plates 14 to contact the partitioning of the material to be detected and continuously pressurize, detecting the pressure resistance and hardness of the partitioning of the material to be detected, when reaching the specified detection standard, the material is observed through the observation window 3, the multi-stage electric push rod 13 is retracted, the heating plate 15 is started, thereby volatilizing the mixed solvent into gaseous solvent, thereby simulating the state of the solvent volatilization in the actual use state and maintaining for a period of time, and then repeating the above detection steps. When the material does not deform, the performance reaches the standard, and the same reason is that the environment of high temperature and gaseous solvent is much worse than the environment of solvent volatilization in actual use. If the partitioning of the material can resist the corrosion of the environment of high temperature and gaseous solvent, the performance in actual use can also be guaranteed. After the above detection is completed, the motor 5 drives the partitioning of the material fixing structure to rotate and the fixed partitioning of the material to be detected to rotate to the vertical state, then the acid pump 12 on the pipe connection of the concentrated sulfuric acid tank 9 is opened to spray the concentrated sulfuric acid solution in it to the partitioning of the material to be detected, after spraying for a period of time, the other side is sprayed for the same time and dose, then after standing for a period of time, the acid pump 12 on the pipe connection of the aqua regia tank 10 is opened to repeat the above operation, after standing, the above detection steps are repeated. The same reason is that the amount of concentrated sulfuric acid and aqua regia sprayed during detection is many times more than that in actual use. If the partitioning of the material can resist the corrosion of such a large amount of concentrated sulfuric acid and aqua regia, the performance in actual use can also be guaranteed. The partitioning of the material after detection is numbered and archived, and the physical performance thereof can be detected after a period of time, thereby ensuring the stability of long-term use.

[0022] Specifically, because a large number of chemical reagents are used in the detection process and a large amount of gaseous solvent is generated in the detection process, and a large amount of strong acid is also used, if the box door 2 is directly opened when the sample is taken out, the gaseous solvent will overflow, and the strong acid and the solvent will flow out, which will not only pollute the environment but also cause damage to related experimental equipment and even cause damage to the human body. In order to overcome the above problems, the bottom of the detection box 1 is communicated with the waste liquid recovery box 16 through a pipeline, a first corrosion-resistant pump 17 and a first electromagnetic valve 18 are arranged on the pipeline between the bottom of the detection box 1 and the waste liquid recovery box 16, the top of the detection box 1 is communicated with the waste liquid recovery box 16 through a pipeline, and a second corrosion-resistant pump 19 and a second electromagnetic valve 20 are arranged on the pipeline between the top of the detection box 1 and the waste liquid recovery box 16. By opening the first corrosion-resistant pump 17 and the first electromagnetic valve 18 and the second corrosion-resistant pump 19 and the second electromagnetic valve 20, the gaseous solvent and the liquid mixed solution in the detection box 1 can be quickly recovered into the waste liquid recovery box 16, so as to avoid pollution of the environment and damage to related experimental equipment and even damage to the human body.

[0023] Preferably, because the gaseous solvent and the liquid mixed solution are recovered into the waste liquid recovery box, negative pressure is generated in the detection box 1, so that the box door 2 cannot be opened, which is not convenient to use. In order to overcome the above problems, the top of the detection box 1 is communicated with the air inlet pipe 21, and a one-way valve 22 is arranged on the air inlet pipe 21. Through the air inlet pipe 21, the air pressure of the detection box 1 and the external environment can be balanced when the gaseous solvent and the liquid mixed solution are recovered into the waste liquid recovery box, so that the situation that the box door 2 cannot be opened due to the generation of negative pressure in the detection box 1 is avoided; at the same time, the one-way valve 22 can effectively prevent the gaseous solvent in the detection box 1 from volatilizing to the outside of the detection box 1, so as to ensure that the external environment is not polluted.

[0024] Preferably, even if the gaseous solvent and the liquid mixed solution are recovered into the waste liquid recovery box 16 under the action of the first corrosion-resistant pump 17 and the second corrosion-resistant pump 19, a small amount of gaseous solvent and liquid mixed solution will still remain in the detection box 1. In order to overcome the above problems, a horizontal pipe 23 is arranged in the upper part of the detection box 1, a plurality of flushing nozzles 24 are arranged at the bottom end of the horizontal pipe 23, and one end of a high-pressure water pipe 25 is communicated with the upper end of the horizontal pipe. The high-pressure water pipe 25 sprays water from the flushing nozzles 24 through the horizontal pipe 23, so as to flush the solution remaining on the components in the detection box 1 and absorb or liquefy the residual gaseous solvent, and then recover them into the waste liquid recovery box 16, so as to ensure that there is no gaseous solvent and liquid mixed solution remaining in the detection box 1 when the box door 2 is opened.

[0025] Specifically, the front bottom of the detection box 1 is provided with a baffle 26. Through the baffle 26, the chemical mixed solution falling to the bottom of the detection box 1 can be prevented from flowing out between the box door 2 and the detection box 1, so as to avoid the outflow of the chemical mixed solution.

[0026] More specifically, the detection box 1 is provided with a polytetrafluoroethylene lining layer 27. The polytetrafluoroethylene lining layer 27 can resist chemical solvents and strong acid corrosion, ensuring long-term use of the detection box 1.

[0027] Preferably, the components in the present application that can be in contact with chemical reagents are made of strong corrosion-resistant materials, such as polytetrafluoroethylene. The components in contact with chemical reagents are made of strong corrosion-resistant materials, which can ensure long-term use.

[0028] Further, the partitioning batten material fixing structure of the embodiment includes a crossbar 28, the rear end of which is fixedly connected with the output shaft of the motor 5, and the two ends of the crossbar 28 are fixedly connected with the middle part of a fixed block 29, respectively. The fixed block 29 is internally provided with a sliding cavity 30, and the sliding cavity 30 is internally provided with two sliding blocks 31. A first through slot 32 is formed on the side of the fixed block 29 away from the crossbar 28. One end of the sliding block 31 is connected with a connecting rod 33, and the other end of the connecting rod 33 is connected with one end of a fixed plate 34 through the first through slot 32. A second through slot 35 is formed on the bottom of the fixed block 29, and one end of a screw rod 36 is connected with the bottom of the sliding block 31. The sliding block 31 cannot pass through the first through slot 32 or the second through slot 35, and the other end of the screw rod 36 is fixedly connected with a nut 37 through the second through slot 35. When the present application is used, the two ends of the partitioning batten material to be detected are placed between the two fixed plates 34 of the corresponding end fixed blocks 29, the two fixed plates 34 are moved to clamp the ends of the partitioning batten material to be detected on the corresponding side, and then the nut 37 is tightened to fix the sliding block 31, so that the connecting rod 33 and the fixed plate 34 are fixed, thereby conveniently fixing the partitioning batten material to be detected.

[0029] Further, the two ends of the crossbar 28 are telescopic rod structures. The telescopic rod structures at the two ends of the crossbar 28 facilitate adjustment of the length of the crossbar 28 according to the length of the partitioning batten material to be detected, and facilitate use.

[0030] Further, the box door 2 is provided with a corrosion-resistant sealing strip 38. The sealing strip 38 can increase the sealing property between the box door 2 and the detection box 1, and avoid spillover of strong acid solution, solvent or gaseous solvent during spraying.
