Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction, in particular to a chimney-type fineness modulus adjustment and dust reduction device. Background Art

[0002] The sand and gravel aggregate processing system mainly produces useful materials into sand and gravel aggregates. During the production process, fine particles will be blown away by the natural wind, resulting in a poor image of civilized construction on site. At the same time, the flying dust has a great impact on the surrounding residents and is very likely to cause complaints from surrounding residents. In addition, after being blown away by the natural wind, the fineness modulus of the sand increases, which has a certain impact on the quality of the finished concrete product. It is easy to cause pipe blockage when pumping concrete, and it is easy to cause loose vibration to form cavities, resulting in reduced concrete strength.

[0003] In existing public literature, the utility model patent with patent publication number CN108554104A discloses a dust removal device for a cupola furnace. This device uses a dust removal system to achieve physical dust reduction by gravity followed by spraying for dust removal, changing the existing single dust removal method. This device offers excellent dust removal efficiency and high efficiency. The spiral wind entering the spray barrel is in the opposite direction of the water mist, tightly binding small particles to the mist for thorough dust removal. Furthermore, this device has a simple structure, is easy to disassemble, and facilitates cleaning and maintenance. It is highly practical and worthy of widespread promotion. However, this technology still has the following drawbacks.

[0004] During the chimney-type fineness modulus adjustment and dust reduction process, although dust removal is required through spraying, the removed dust impurities will diffuse and flow outward, making it difficult to connect to the feed position for collection. This results in fine particles being difficult to guide into the designated position even after atomization and spraying, resulting in an increase in the fineness modulus of the sand material, which affects the quality of the finished concrete product. For this reason, a chimney-type fineness modulus adjustment and dust reduction device is needed. Utility Model Content
