Description

Technical Field

[0001] The utility model relates to the technical field of concrete production equipment, in particular to a dust reduction pipeline. Background Art

[0002] The concrete production industry uses cement, sand, gravel and water as raw materials, and carries out processes such as mixing, pouring and hardening to produce concrete products of various specifications and models. A large amount of dust will be generated during the production process of concrete. Workers who work in a dusty environment for a long time will cause certain damage to their lungs, and dust reduction equipment is needed to control it.

[0003] A Chinese patent discloses a dust reduction pipe for concrete production (authorization announcement number CN220194401U). The patented technology can filter dust particles using the sieve plate through the coordinated use of components such as a sieve plate and a high-pressure nozzle, and then clean the sieve plate through the high-pressure nozzle, and simultaneously adsorb the raised dust through water mist; however, during the inclined spraying process of the high-pressure nozzle, the water flow impacts the metal sieve plate for flushing, and water droplets splash during the flushing process. The metal sieve plate is located in the metal filter tube, causing the water droplets to pass through the holes on the metal sieve plate and easily stay inside the first telescopic hose, the metal filter tube and the second telescopic hose, and will drip down along the first telescopic tube onto the equipment. There is no waterproof operation as a whole, and the mixture of water stains and dust is easy to stick to the back of the metal sieve plate, which cannot be flushed by the high-pressure nozzle. Therefore, we propose a dust reduction pipe to solve the above problems. Utility Model Content
