[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] Example 1
[0024] See also Figures 1 to 6 The utility model provides a technical solution: a buffer dust removal device for a coal dropping point of a belt conveyor, comprising a coal dropping box 1 and a fan 2, a material dropping dust removal component 3 is provided at the bottom of the coal dropping box 1, an air inlet end of the fan 2 is connected to a diverter pipe 4, an air outlet end of the fan 2 is connected to an air outlet pipe 5, and buffer components 6 are provided on both sides of the interior of the coal dropping box 1;
[0025] The unloading dust removal assembly 3 includes a unloading plate 31 installed at the bottom of the coal unloading box 1, a groove 32 is provided inside the unloading plate 31, through holes 33 are provided around the inner wall of the unloading plate 31, and first mounting plates 34 are installed on both sides of the outer surface of the unloading plate 31. A connecting plate 35 is connected to the lower surface of the unloading plate 31, and a connecting seat 36 is installed on the top of the connecting plate 35. The connecting seat 36 is located inside the groove 32, and a collecting groove 37 is provided inside the connecting seat 36. An activated carbon filter plate 38 is provided inside the collecting groove 37. Both ends of the diverter pipe 4 pass through And extends to the interior of the groove 32, and the two ends of the diverter pipe 4 are located on both sides of the activated carbon filter plate 38. A filter screen 39 is installed on the inner side of the connecting plate 35, and the filter screen 39 is located in the blanking plate 31. Second mounting plates 310 are installed on both sides of the outside of the connecting plate 35. Bolts 311 are commonly connected to the inside of the first mounting plate 34 and the second mounting plate 310. The first mounting plate 34 and the second mounting plate 310 are connected by bolts 311. The outside of the bolts 311 is connected to a nut 312, and the nut 312 is located at the bottom of the second mounting plate 310;
[0026] The buffer assembly 6 includes a mounting seat 61 installed inside the coal drop box 1. Several groups of equidistant buffer springs 62 and telescopic rods 63 are installed inside the mounting seat 61. The buffer spring 62 is located outside the telescopic rod 63. The top of the buffer spring 62 and the telescopic rod 63 are jointly installed with a slide 64. The slide 64 is located inside the mounting seat 61. A buffer pad 65 is installed on the top of the slide 64. The buffer pad 65 is made of rubber and the size of the buffer pad 65 is larger than that of the slide 64.
[0027] Before the coal falls from the unloading dust removal assembly 3, the fan 2 is started first. When the coal falls from the coal box 1, it is buffered by the two buffer assemblies 6 to prevent the coal from being broken due to the strong impact force when it falls. When the coal is unloaded from the unloading dust removal assembly 3, since the fan 2 is in operation, when the coal falling from the unloading plate 31 generates dust, the coal is filtered through the filter 39, and the dust enters the groove 32 through the arrangement of several groups of through holes 33. Since an activated carbon filter plate 38 is arranged on one side of the collection tank 37 and inside the groove 32, the dust is filtered by the activated carbon filter plate 38. The clean gas after filtration is transported out through the diverter pipe 4 and the outlet pipe 5. The filtered dust can fall into the collection tank 37. The arrangement of several groups of through holes 33 can improve the dust removal effect, thereby reducing the dust generated when the coal falls.
[0028] When cleaning the dust in the collection tank 37 later, the user rotates and removes the two nuts 312 from the bottom of the bolt 311, and then detaches the bolt 311 from the first mounting plate 34 and the second mounting plate 310, and the connecting seat 36 installed on the top of the connecting plate 35 is detached from the groove 32, and the connecting plate 35 can be separated from the blanking plate 31. At this time, the activated carbon filter plate 38 and the filter screen 39 are taken out from the blanking plate 31 and the groove 32 respectively, and the dust in the collection tank 37 can also be cleaned.
[0029] Example 2
[0030] like Figures 1 to 6 In the second embodiment, other structures remain unchanged. The difference from the first embodiment is that the coal is buffered and falls through two buffer components 6. When the coal falls, it first contacts the buffer pad 65. The buffer pad 65 is made of rubber to reduce the phenomenon of coal being broken. When the buffer pad 65 is impacted, the slide 64 installed at the bottom of the buffer pad 65 is located in the mounting seat 61 and moves. At this time, the slide 64 squeezes the buffer spring 62 and one end of the telescopic rod 63. The setting of the buffer spring 62 and the telescopic rod 63 can reduce the potential energy of the coal falling, and finally falls from the unloading dust removal component 3.
