Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of material transportation, in particular to a coal drop pipe anti-blocking device. Background Art
[0002] Coal contains a certain amount of moisture and can absorb moisture from the air. During the stacking process, some of the coal at the bottom and surface will agglomerate. When the coal is transported, the coal agglomerates (hereinafter referred to as coal blocks) can easily cause blockage at the outlet of the coal drop pipe.
[0003] According to the search, Chinese patent literature, announcement number: CN220363890U, discloses a device for preventing the coal drop pipe from blocking. This solution forms a relatively simple anti-blocking device through the arrangement of the tube body, rotating shaft, servo motor and fixed rod body. When agglomerated coal blocks fall into the tube body, the rotating shaft rotates, so that the stirring blades will break up the coal blocks, thereby achieving the purpose of preventing blocking. The setting of the guide plate allows the coal blocks to fall after being broken up by the stirring blades, thereby making the coal blocks loose and small pieces of coal. The setting of the shaft seat, bearing, end shaft and sleeve can effectively reduce costs, and can also facilitate disassembly and maintenance. Moreover, the sleeve is set to be a quadrilateral, which can facilitate the setting of the stirring blades. The stirring blades are set to be inclined, which has a better breaking up effect on agglomerated coal blocks. The stirring blades located on the adjacent sides of the sleeve are inclined in opposite directions, which is also to achieve a better breaking up effect. The nylon shock-absorbing sleeve can effectively achieve the stability and firmness of the connection between the end shaft and the sleeve, and has a certain degree of flexibility, which can reduce the impact on the bearing and reduce the noise. The setting of the foam material can effectively reduce noise and vibration. The setting of the fixed rod and the baffle can make the agglomerated coal blocks be blocked and dispersed for the second time here. Preferably, the horizontal position of the two rotating shafts is above the horizontal position of the fixed rod, and the angle between the axis of the rotating shaft and the axis of the fixed rod and the horizontal plane is 40°-60°, which can form a better dispersion effect. However, the anti-blocking device for the coal drop pipe still has defects during use, and the device does not have a good screening device. Utility Model Content
