电动笼式碎上机结构简单、生产率高,所以在炼钢厂和耐火材料厂广泛用于生产耐火粘土粉,作粘结原料。这种设备设计时,由于防尘考虑较少,一般只在笼外设防尘罩。但罩是用薄板焊成,所以轴端防尘比较困难。在工厂常见用泥堵或挂橡皮圈挡尘,效果不好,影响企业防尘达标和危害工人身体健康。 解决轴端跑尘简单而又有效的办法是设法使罩内形成“负压”。为此可把与内笼和外笼相联接的法兰盘面“A”设计成斜面,见图,使之在与外笼和内笼装配后,笼板“a”与轴垂直线为一夹角a,这样,内笼和外笼板“a”就象家用电风扇的“叶片”。所以笼子转动方向确定后,依据生产工艺,正确设计笼板“a”的倾角。的方向,使叶片转动时把空气吸进防尘罩内,形成负压而达到防止轴端跑尘的目的,效果良好。
Electric cage shredder machine is simple in structure and high in productivity. Therefore, it is widely used in the manufacture of refractory clay powder in steelworks and refractories as the raw material for bonding. This equipment design, due to less dust considerations, generally only outside the cage dust cover. However, the cover is welded with sheet metal, so the shaft end dust is more difficult. In the factory common mud blocking or hanging rubber ring dust, the effect is not good, affecting corporate dust standards and endanger the health of workers. A simple and effective way to solve the problem of shaft-end dust is to try to create a “negative pressure” in the hood. For this purpose, the flange surface “A” associated with the inner cage and the outer cage may be designed as a bevel so that after being assembled with the outer cage and the inner cage, the vertical “a” of the cage plate is a clamp Angle a, so that the inner cage and outer cage plate “a” is like a “leaf” of a household electric fan. Therefore, after determining the direction of cage rotation, according to the production process, the correct design of the plate a "dip angle. The direction of the leaves when the air suction into the dust cover, the formation of negative pressure to achieve the purpose of preventing dust from the shaft end, the effect is good.
