Problems solved by technology
[0002] The existing high-skilled colleges provide students with practical and theoretical learning, and practical operation learning for engine maintenance, welding technology training, etc., but the existing test benches are fixed on the bottom surface for contact, and the vibration generated by the engine will make the test bench unstable. And it produces vibration and noise, which greatly affects the experimental environment, and during welding training, a large amount of smoke is generated, so that the training place is polluted to a certain extent

The invention provides noise-reducing and smoke-removing equipment for improving the air environment of a teaching laboratory. The noise-reducing and smoke-removing equipment comprises an experiment table. A damping supporting device is arranged at the bottom of the experiment table, and a silencing plate is arranged on the table top of the experiment table. A bending plate connected to the side edge of the experiment table in a sliding mode is further included, and a lead screw driving device used for driving the bending plate to move longitudinally is arranged on the experiment table. An air extractor is arranged on the surface, facing the experiment table, of a top plate of the bending plate, and the exhaust end of the air extractor is connected with a purification system. A plurality of ventilation wall holes are formed in the top plate in the circumferential direction and connected with a cooling fan. According to the embodiment, an engine assembly on the experiment table is ensured to run stably through the damping supporting device, and smoke generated during welding practice is absorbed, so that the laboratory environment is purified.
Description
technical field [0001] The invention relates to the technical field of teaching experiments, in particular to a noise-reducing and dust-removing device for improving the air environment of a teaching laboratory. Background technique [0002] Existing high-skilled colleges provide practical and theoretical study for students, and practical operation learning for engine maintenance, welding technology training, etc., but the existing test benches are fixed on the bottom surface for contact, and the vibration generated by the engine will make the test bench unstable. Moreover, vibration and noise are generated, which greatly affects the experimental environment, and during welding training, a large amount of smoke is generated, thereby polluting the training place to a certain extent. Contents of the invention [0003] In view of this, the present invention provides a noise-reduction and smoke-removal device for improving the air environment of a teaching laboratory, so as to...
