Embodiment

[0009] The whole system is subdivided into three parts: heating system, automatic ejection system and circuit control system. The heating system specifically includes a high-frequency heater, an infrared temperature sensor and a cooling exhaust system. High-frequency heating technology uses magnetic force to directly act on the metal to be heated, and can reach high temperature in a short time, so it has the advantages of fast heating speed, high efficiency, small size and energy saving. The high-frequency heater can adjust the heating time, heating power, holding time, holding power and cooling time by controlling, which greatly improves the accuracy of temperature control. Choose an infrared temperature sensor with a measurement range of 500-1500°C, the accuracy is controlled at ±1%, and the final measured temperature is compensated through calibration. The cooling and exhaust system uses circulating water to cool the heater. The cooling time of the heater is adjusted by co...

Abstract

The invention discloses a goggle melting performance detection system. The whole system is subdivided into a heating system, an automatic ejection system and a circuit control system. The heating system specifically comprises a high-frequency heater, an infrared temperature sensor and a cooling exhaust system. The high-frequency heater and the infrared temperature sensor are used for achieving temperature control as high as 1400 DEG C, and a pneumatic switch and a control system circuit are used for achieving pressing plate loading and ejection automation. The test process of the detection system is simple, scientific and objective, and the test result has high repeatability and accuracy.

Description

technical field [0001] The invention belongs to the field of performance detection of protective products, and in particular relates to a detection system for the melting performance of goggles. Background technique [0002] People will encounter various heat sources in activities such as production, life and life rescue, and the resulting heat damage is an important factor that causes the greatest harm, injury or death. Various fires, explosions, high-temperature furnaces, electric arcs, molten metal splashes, and welding arcs have thermal injuries or potential thermal hazards. The temperature of these heat sources may be 70-1400°C, and the heat energy of the heat sources may reach the human body through contact, radiation or thermal convection, causing harm to the human body. The eyes are one of the most compact and fragile parts of the human body, and are also the most sensitive to various heat source hazards. Blocking the heat energy from reaching the eyes through the p...
