Technical Field

[0001] This utility model relates to the technical field of hazardous chemical testing equipment, specifically a testing chamber for chemicals. Background Technology

[0002] Laboratory tests for highly viscous and hazardous chemicals typically use electric heating. The advantage is simple temperature control, but the disadvantages are: 1. Hazardous chemicals generally pose flammable and explosive risks, and electric heating can easily cause combustion or explosion. 2. Ordinary experimental equipment has a door-type opening and closing structure, and most do not have observation holes, making it impossible to observe and record the test status in real time.

[0018] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0019] A preferred embodiment of the chemical testing chamber provided by this utility model is, for example... Figures 1 to 3The following is an illustration: A test chamber for chemicals includes a test chamber 1. Three supports 2 are fixedly installed on the bottom surface of the test chamber 1, providing stable support. A vacuum pipe 3 is connected to the top surface of the test chamber 1 and is connected to a vacuum pump. A discharge hole is located in the center of the bottom surface of the test chamber 1 for easy discharge and collection of materials after testing. This discharge hole is connected to a metal discharge pipe 4. Two flange sight glasses 5 are installed on the front of the test chamber 1, symmetrically distributed at the front and rear positions about the center line of the front of the test chamber 1. The flange sight glasses 5 facilitate supplemental lighting and observation of material conditions. A quick-opening flange 7, a thermometer 8, a vacuum valve 9, and a negative pressure gauge 10 are installed on the top surface of the test chamber 1. The vacuum valve 9 is connected to nitrogen or compressed air. The outer wall of the test chamber 1 near the lower end is connected to an external pipe 6, which is equipped with a steam regulating valve. The outer wall of the test chamber 1 near the upper end is provided with a steam outlet 11. The side of the steam outlet 11 is provided with an arc-shaped notch 17. The inner wall of the arc-shaped notch 17 is provided with an arc-shaped bayonet 18. An arc-shaped retaining strip 12 is slidably provided in the arc-shaped bayonet 18. A connecting block 13 is fixedly installed at the end of the arc-shaped retaining strip 12. An annular plate 14 is fixedly installed at the end of the connecting block 13. A pipe 15 is fixedly sleeved on the inner wall of the annular plate 14. A copper pipe 16 is fixedly installed on the inner wall of the pipe 15. The copper pipe 16 can be used to condense the steam and prevent it from being damaged by high temperature during discharge. At the same time, the arc-shaped retaining strip 12, connecting block 13, and annular plate 14 can be used to quickly detach the pipe 15 from the steam outlet 11, which is convenient for maintenance of the copper pipe 16.

[0020] Working principle: Connect test chamber 1 to external steam, such as a main steam pipeline or a steam generator. Control the steam flow and temperature through the steam regulating valve to heat the jacket of test chamber 1 to achieve the required test temperature. The condensate from the heated steam is pollution-free and can be directly discharged into a ditch or collected for treatment. Place the high-viscosity, hazardous chemicals to be tested into test chamber 1 by opening the upper quick-opening flange 7, close the quick-opening flange 7, then turn on the vacuum pump to create a vacuum. Adjust the vacuum pump's suction power until the required vacuum level is reached. Open the steam regulating valve to adjust the steam temperature until the required temperature is reached. Finally, observe the steam through the flange sight glass 5.

[0021] Here, if the material viscosity is high, relying solely on gravity for discharge will take a long time and result in incomplete discharge. In this case, the vacuum extraction port can be closed, the source inlet can be opened, and the laboratory gas source can be connected. Depending on the degree of danger of the test material, nitrogen or compressed air can be introduced, and the discharge valve can be opened. The air pressure can be used to make it easier for the high-viscosity test material to be discharged and cleaned from the discharge port.

[0022] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification of this utility model can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
