Problems solved by technology

The currently used unit combustion test device only has a smoke exhaust pipe and a gas collection hood above the combustion chamber, without considering the harmful gas generated by the burning of residual drippings on the trolley after the end of the test, and the harmful gases generated by the burning of drippings. Harmful smoke seriously endangers the health of test personnel and affects the oxygen content in the air, thus affecting the accuracy of test results

Abstract

The invention relates to the technical field of building material or product single burning item test detection and particularly discloses a self-controlled single burning item test smoke-exhausting assisting device. The self-controlled single burning item test smoke-exhausting assisting device comprises a burning chamber, a gas collecting hood is arranged at an outlet in the top end of the burning chamber, and a collector is mounted at the top end of the gas collecting hood and connected with a fan through a smoke-exhausting pipeline. The device is characterized in that a gas collecting assisting hood is mounted above the opening of the burning chamber, the top end of the gas collecting assisting hood is connected with a smoke-exhausting assisting pipeline, the tail end of the smoke-exhausting assisting pipeline communicates with the smoke-exhausting pipeline, an electric control device is arranged in the communicating position of the smoke-exhausting assisting pipeline and the smoke-exhausting pipeline, and both the electric control device and the fan are connected with a PLC control system. The self-controlled single burning item test smoke-exhausting assisting device provided by the invention is simple in structure and flexible in application, the problem that in an existing test device, harmful smoke generated from burning of residual dripping harms the body health of the test personnel is solved, and the accuracy of detection data is improved.

Description

(1) Technical field [0001] The invention relates to the technical field of single combustion test detection of building materials or products, in particular to an autonomously controllable auxiliary smoke exhaust device for single combustion test. (2) Background technology [0002] With the implementation of GB 8624-2006 "Classification of Combustion Behavior of Building Materials and Products", single combustion test is widely used as an important test item. The currently used unit combustion test device only has a smoke exhaust pipe and a gas collection hood above the combustion chamber, without considering the harmful gas generated by the burning of residual drippings on the trolley after the end of the test, and the harmful gases generated by the burning of drippings. Harmful smoke seriously endangers the health of test personnel and affects the oxygen content in the air, thereby affecting the accuracy of test results. (3) Contents of the invention [0003] In order t...
