The product bin is usually connected below to a coal feeder through a connecting channel, and coal and the like flow out of the coal feeder through the channel, and the coal feeder is transported to other places through a belt. Due to the problems of coal quality and storage time of commercial coal, the phenomenon of wall hanging of the commercial coal often occurs in a product bin in the using process, so that the coal blending and feeding machine does not drop, and the outward transportation of a commercial coal train for bridge mine and the commercial coal blending quality are seriously influenced.
The existing wall hanging method for treating commercial coal in a product bin mainly comprises the following steps:
1. and (4) blasting the blasting team by the aid ventilation team at a feed inlet of the coal feeder.
2. After years of practice, the water pipe is used for directly flushing the water in the bin on an annular overhaul platform which is artificially arranged on the waist part of the product bin and is about 10 meters high.
3. Manually knocking a coal feeder feeding chute on a waist annular maintenance platform with the height of about 10 m of a product bin by using a sledge hammer.
The above three methods have many problems, such as:
the first method comprises the following steps: when a recourse ventilation team is shot at a feed port of a coal feeder to process the problem of coal bunker wall hanging, firstly, long time is needed for compiling approval site construction measures, the whole loading system stops loading for at least half a day in the construction process, then, the whole loading system needs to manually drill into the feed port of the coal feeder to make a hole and shot, 5-6 persons are needed for warning and construction in the whole process, meanwhile, the shot process has great damage to the coal feeder, and the shot often causes the problems that pre-buried bolts at the feed port of the coal feeder shake off, the body of the coal feeder deforms and the like.
The second method comprises the following steps: adopt artifical water with towards the storehouse, need about 3 people cooperation, take heavy water pipe, climb 10 meters high maintenance platform and dash the storehouse, inefficiency, the unable assurance of safety.
The third method comprises the following steps: the hammer is used for knocking a feeding chute of the coal feeder, so that the deformation of a body of the coal feeder is often caused, the coal stagnation treatment on a feeding port of the coal feeder is effective, and the problem of coal hanging of a product bin cannot be solved.
The utility model discloses a utility model patent of application number is "CN 201620808223.5" again discloses raw coal scuttle of integration, including the coal scuttle, the coal scuttle includes at least one shrimp shape hopper, the feeder is connected to shrimp shape hopper lower extreme, bidirectional hydraulic pressure picture peg door is established to shrimp shape hopper lower part, establish bayonet expansion joint between bidirectional hydraulic pressure picture peg door and the feeder, a plurality of rapping air hammer is established to shrimp shape hopper outer wall, rapping air hammer passes through the PLC module electric cabinet and is connected with the disconnected coal signal acquisition device who establishes in feeder department. In the patent scheme, the problems of coal shed and coal blockage are solved by vibrating the air hammer, and the problem of coal hanging of a product bin cannot be solved;
for another example, the utility model with the application number of "CN 201821582375.3" discloses a built-in coal cleaning platform for a boiler coal bunker, which comprises a coal bunker and a platform; the top of the coal bunker is provided with an opening, the platform is fixedly installed on a cross beam of the coal bunker, guardrails are fixedly installed on the periphery of the platform, and a vertical ladder convenient for cleaning personnel to go up and down is arranged between the opening and the platform inside the coal bunker.
