Description

Technical Field

[0001] The utility model relates to the technical field of pulverized coal bunker blockage clearing, in particular to a rotary blockage clearing machine. Background Art

[0002] In coal ore processing, the crushed pulverized coal is put into the silo for subsequent processing. In coal ore processing, in order to reduce dust, water is usually sprayed during the coal ore crushing process to make the dust heavier and fall.

[0003] Although spraying water can remove dust, water will also enter the crushing equipment and mix into the coal ore, causing the humidity of the pulverized coal to increase. Pulverized coal with high humidity is stored in the bin body and is easy to agglomerate and adhere to the bin body. Therefore, the agglomerated pulverized coal is blocked at the output hole of the bin body, and the adhesion of the pulverized coal affects the output of the pulverized coal. In order to accelerate the output of the pulverized coal, a vibrator is usually installed at the output hole of the bin body. For example, a raw coal bin disclosed in a Chinese patent with patent publication number CN204624372U includes a bin body, a vibrator is provided on the bin body, and at least one air inlet is provided on the side wall of the bottom of the bin body. The opening direction of the air inlet is downward, and the air inlet is connected to a hot air pipe.

[0004] Although the vibrator can cause the side wall of the silo to vibrate and accelerate the pulverized coal to slide down, due to its fixed setting, it can only vibrate a certain position of the silo, while the pulverized coal in other parts slides down more slowly. If more vibrators are installed, the cost of use will increase. Summary of the invention

[0027] Example 1

[0028] like Figure 1 , Figure 2As shown, a rotary blockage clearing machine includes a raw coal bin 1, a transition bin 2 and an air vibration hammer 5. The size of the feeding hole at the lower end of the raw coal bin 1 is enlarged, that is, it is larger than the feeding hole size of the raw coal bin 1 involved in the case. This arrangement can reduce the current situation of pulverized coal accumulation and clogging in the raw coal bin 1. The transition bin 2 is arranged below the raw coal bin 1, serving as the feeding hole of the raw coal bin 1 involved in the case, and the transition bin 2 is arranged as a frustum structure. At the same time, the transition bin 2 is divided into an upper and lower section. The inclination degrees of the upper and lower sections of the transition bin 2 are different, that is, the inclination of the upper section is smaller than that of the lower section. This arrangement facilitates the accelerated sliding of the pulverized coal and avoids the movement of the pulverized coal being affected by the relatively slow side wall of the transition bin 2. In order to strengthen the strength of the transition bin 2, a waist reinforcement 21 is arranged at the junction of the upper and lower sections of the transition bin 2, and the waist reinforcement 21 supports the stable placement of the transition bin 2. The air rapping hammer 5 is arranged on the side of the transition bin 2 and can move outside the bin body so as to rapple different positions of the bin body, accelerate the movement of the pulverized coal in the bin body, and avoid the pulverized coal being blocked in the bin body and affecting the output of the pulverized coal.

This arrangement can effectively utilize the air rapping hammer 5 to strike the transition bin 2 or the raw coal bin 1 to accelerate the movement of the pulverized coal. The air rapping hammer 5 is a prior art and is briefly introduced here. It includes a shell, which is a cast pipe. The front end of the shell is fixedly connected to a blind plate, and the rear end of the shell is fixedly connected to a flange.
