The utility model discloses a new type of dust-proof grate for a mine trench mouth, which comprises a grate beam, a first grate bar and a second grate bar. The grate beam comprises two parallel upper opening plates, one end of the upper opening plate is connected with the installation plate, the installation plate is vertically arranged with the upper opening plate, the other end of the upper opening plate is connected with the lower opening plate, and the lower opening plate and the upper opening plate form a funnel-shaped structure. A number of second grate bars and first grate bars are arranged between the opening plates. The first grate bar and the second grate bar are staggered. The distance between the adjacent first grate bar and the second grate bar is equal. The first grate bar and the second grate bar are arranged parallel. The shape of the first grate bar is a funnel shape that fits the upper opening plate part and the lower opening plate part. The utility model makes the grate into a funnel shape, when the material falls, it will impact on the lower opening plate to decelerate and then fall, effectively reducing the dust generated by the material collision, reducing the opening of the ore slot by reducing the area of the outlet, and preventing a large amount of dust overflow.

一种用于矿槽口的新型防尘篦子
本技术属于矿物开采
,具体的,涉及一种用于矿槽口的新型防尘篦子。
技术介绍
在矿山、冶金、水泥等行业的储矿槽,一般由带式输送机转运物料至矿槽上,物料经移动卸料小车的两侧的溜槽、矿槽顶面带式输送机两侧预留的受料槽口卸入矿槽,带式输送机输送物料是连续运行的,在一个矿槽物料满槽后移动卸料小车带料移至下一个矿槽,在移动过程中同时向矿槽卸料,矿槽顶面带式输送机两侧的槽口一般沿带式输送机移动方向通长设置,敞开的槽口面设置有安全防护篦子。带式输送机的移动卸料小车溜槽向矿槽卸料过程中,由于物料下落冲击,在矿槽内产生大量扬尘从敞开的矿槽顶面槽口外溢,污染环境,不利于作业人员身心健康,现有技术中常采用矿槽负压除尘技术来进行除尘,通过在矿槽侧边或顶部设负压通风管抽尘,有效防止矿槽内的尘气通过槽口外溢,采用矿槽负压除尘技术时为了减少除尘系统设计风量,常采用“∏型胶带”对敞开槽口进行局部密封,对于一些不能设置“∏型胶带”的矿槽,就需要大风量负压抽尘,不利于节能,除尘系统初期设资和运行成本较高,为了解决这一问题,本技术提供了以下技术方案。
