The utility model discloses an oil return blockage alarm device for a ball mill dilute oil station, which includes a protective sleeve, a photoelectric liquid level sensor and an alarm circuit. The alarm circuit is electrically connected with the photoelectric liquid level sensor. The photoelectric liquid level sensor is arranged on the side wall of the protective sleeve sleeve, and the protective sleeve sleeve sleeve is welded on the outer wall of the oil tank outside the port of the oil return filter network. When the oil return filter network is blocked When the speed of oil return is much lower than that of oil return, the oil will overflow from the interface between the oil return filter and the oil tank. Because of the existence of the protective casing welded on the outer wall of the oil tank outside the port of the oil return filter, the oil will not leak directly to the surface of the oil tank, but gather in the space surrounded by the protective casing. When there is too much lube accumulated oil, the liquid level will not pass through the photoelectric liquid level. After the sensor, the switch in the sensor will close and then supply power to the bell and the alarm indicator through the intermediate relay to give an alarm. The utility model can prevent the waste of resources and the lubrication effect of the ball mill.

一种球磨机稀油站回油堵塞报警装置
本技术涉及稀油润滑设备
,具体地说是一种球磨机稀油站回油堵塞报警装置。
技术介绍
球磨机主要应用于矿山和电厂,在球磨机的配套设备中稀油站承担着为球磨机进料端和出料端轴承提供润滑油的作用.在传统的稀油站中对出油口供油压力和流量都有严格的要求。稀油站包括油箱、齿轮泵、单向阀、安全阀、双筒网式过滤器、冷却器和供油管路,润滑油由齿轮泵从油箱中吸出,经单向阀、安全阀、双筒网式过滤器和冷却器通过供油管路送入设备的润滑点。参见图1,为现有技术中稀油站回油口结构示意图,如图1所示,润滑之后的润滑油从润滑点经回油管1回到油箱3,为了对回油中的杂质进行过滤,将回油管1的出油端设置在回油过滤网2内部,回油从回油管1流出后经过回油过滤网2的过滤进入油箱3。然而,现有技术中,回油过滤网2经过多次过滤后会被大量杂质堵塞,造成回油过滤速度缓慢,使过滤速度远远小于回油速度,从而造成大量润滑油从回油过滤网2的上端口溢出,不仅造成了资源浪费也影响了对球磨机的润滑。
