JPH0732550U - Acid rain tester - Google Patents

Abstract

(57) [Summary] [Purpose] To obtain a tester that can reliably test by acid rain. [Structure] A raindrop tank with a large number of small holes on the bottom and a shower for rain were installed above the test chamber, and a hot air generation tank was installed to dry the sample in the test chamber.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tester for dropping acid rain, which is a problem of environmental destruction.

[0002]

[Prior art]

 Conventionally, the test was performed using a corrosion tester (salt spray tester, cast tester). In this case, the chemical solution is sprayed from the nozzle, and the chemical solution is attached to the entire surface of the sample piece by free fall to corrode it. It was tested for acid rain.

[0003]

[Problems to be solved by the device]

 An object of the present invention is to provide a tester capable of surely and quickly conducting an acid rain test by concentrating and dropping a chemical solution on a sample piece to give an impact, and drying it rapidly.

[0004]

[Means for Solving the Problems]

 The means of the present invention are as follows.

An acid rain test in which a raindrop tank having a large number of small holes on the bottom and a shower for raining are provided in the upper part of the test chamber, and a hot air generation tank for drying a sample placed on a sample table in the test chamber is installed. Machine.

[0006]

[Action]

 In the case of the raindrop test, the chemical solution is supplied from the water pump 3 to the raindrop tank 4, and the chemical solution is circulated from the overflow 12 at the upper part of the tank. Raindrops in the raindrop tank are continuously dropped onto the sample set on the sample table 6, and when the raindrop time set by the timer 7 has elapsed, hot air is supplied from the hot air generating tank 8 to dry the sample, and then the exhaust hole. Eject warm air above 10. The above operation is repeated.

Similarly in the shower test, the chemical liquid in the chemical liquid tank 2 is supplied to the shower nozzle 5 by the pump 3 and sprayed on the sample. When the set shower time arrives, hot air is applied to the sample from the hot air generating tank 8 to warm and dry the sample.

【Example】

 Reference numeral 1 in the figure is a test chamber equipped with a sample table 6, 2 is a chemical solution tank having a supply port 11, and a pipe 15 is connected to the test chamber 1. Reference numeral 3 denotes a water pump, which is connected to the chemical liquid tank 2 by a pipe 16, the raindrop tank 4 above the test chamber 1 by a pipe 17 and the shower nozzle 5 by a pipe manifold 17 ', and a pipe 17 for a raindrop switching valve. 13, the fixed valve 18 is interposed, and the nozzle switching valve 9 and the flow meter 19 are interposed between the manifold 17 '. The overflow pipe 12 is led out above the raindrop tank 4 and connected to the middle of the pipe 20 from the chemical tank 2 to the raindrop tank 2 having a large number of small holes 40 on the bottom surface by the pipe 20 with a drain valve 21 interposed. . Reference numeral 7 is a timer, 8 is a hot air generating tank, 30 is a control box, 31 is a drain valve, 32 is an indoor light, 33 is an inspection window in the test chamber 1, 34 is a door, and 35 is a stirring pump.

[0009]

[Effect of device]

 According to the present invention, raindrops, showering and drying can be reliably repeated, and acid rain can be conducted by a simple facility compared with the conventional free fall method, and the test can be performed smoothly.
