Description

Technical Field

[0001] The utility model relates to the technical field of concrete production, in particular to an environmentally friendly dust reduction device for high-performance premixed concrete feeding. Background Art

[0002] High-performance concrete is a concrete made with modern concrete technology. Compared with ordinary concrete, it is not a type of concrete, but a combination of concrete that is suitable for industrial production and construction with broad dynamic sustainable development as the basic requirement.

[0003] When high-performance concrete is produced, loading will be carried out first. Loading refers to the process of transporting the sand and gravel aggregates used to produce high-performance concrete to the mixing station through a conveyor belt for mixing. When the sand and gravel aggregates enter the mixing station, they will be fully mixed with the water added in the mixing station, so that the sand and gravel aggregates will become high-performance concrete that can be poured on site.

[0004] In the prior art, since sand and gravel aggregates contain a large number of tiny solid particles, when the conveyor belt conveys the sand and gravel aggregates, the tiny solid particles will float out to form dust. Especially in a windy environment, the tiny solid particles in the sand and gravel aggregates will form larger dust, which will affect the on-site environment and cause damage to the health of the construction workers on site.

[0005] For example, in the environmentally friendly dust suppression device for high-performance ready-mixed concrete feeding disclosed in Chinese patent CN218653649U, the spray head can use water mist to suppress the dust on the conveyor belt, and the adjustment mechanism can adjust the spray angle of each spray head to make the spray range of the spray head wider. During the whole process, the dust can be quickly suppressed by the water mist, thereby reducing the impact on the environment, making the manufacture of high-performance concrete more environmentally friendly, and on the other hand, reducing the damage to the health of construction workers.

[0006] However, the mounting base of the device is mounted on the top of the mounting plate by bolts during use, and when the spray head is damaged, it is inconvenient to replace it.

[0007] For this reason, we urgently need to provide a high-performance environmentally friendly dust suppression device for premixed concrete feeding. Utility Model Content
