Technical Field
The invention relates to the field of anti-blocking pipes of mining filling pumps, in particular to equipment for reducing pipe blocking of a mining filling pump and an alarm system.
Background
In mining industry, such as working operation under a coal mine, waterproof and anti-collapse treatment is generally carried out on surrounding rocks around excavated underground engineering, and the prepared mortar filler is pressed into cracks of the rocks to enable the mortar filler to flow and diffuse along the cracks to form a low-water-permeability combination with certain strength, so that the strength of the surrounding rocks is improved, water flow is cut off, the effects of preventing water flow from leaking in and surrounding rocks from collapsing are achieved, and safety guarantee is provided for the working operation under the coal mine. In operation, the pipeline is usually sent into the crack, mortar is injected into the pipeline by using a filling pump, and the crack is filled.
In the processes of stirring, conveying and the like of the mortar, air can be wrapped in the mortar to form bubbles. The filling pump is with mortar input pipeline in-process, and inside the mortar that has the bubble constantly got into the pipeline, the gathering can take place for numerous bubbles in the pipeline, and the bubble reaches the easy air-resistor that forms behind certain gathering in the pipeline, and simultaneously, the filling pump can lead to the high reduction of mortar when inhaling the mortar for the air gets into the pipeline easily, makes the filling pump probably inhale the air, leads to the possibility greatly increased of air-resistor. Air lock can create a pipe blockage problem. The existing treatment mode is that an exhaust valve is additionally arranged at a certain position of a pipeline to exhaust gas, the exhaust valve can only be used for locally exhausting the pipeline, and the problem of air resistance at other positions cannot be avoided; and for the bubbles in the mortar, the exhaust valve can play a good role in exhausting only when a plurality of small bubbles in the mortar are gathered into air masses, and for the small bubbles wrapped in the mortar, the exhaust valve is difficult to exhaust. Therefore, the pipeline is exhausted through the exhaust valve to avoid air resistance, obvious limitation is realized in use, and the problem of pipe blockage of the mining filling pump cannot be effectively solved.
