Embodiment 1

[0025] Such as figure 1 , 2 , shown in 3, the present invention is set a rectangular base frame 1 that shape is identical with the pit mouth of the roasting tunnel but the area is greater than the pit area by the pit mouth area of ​​a single roasting tunnel, the base frame 1 is placed on the pit mouth of the roasting tunnel, the base Axial slide rails 101 are installed on both sides of the long axis of the frame, and a hopper frame 2 is movably placed on the base frame. The hopper frame is composed of four sides. The hopper 7 for filling materials, the bottom of the hopper is a protruding conical bottom 701, the top of the conical bottom is a discharge port 703, a movable insert 702 is set on the discharge port, and the hopper frame is set on the side in contact with the axial slide rail There is a sliding device 4, and the sliding device can use pulleys, balls or wire ropes to pull the movement mechanism, so that the hopper frame can move back and forth above the roasting tu...

Embodiment 2

[0030] Such as figure 1 , 2 , 4, 5, and 6, on the basis of the aforementioned embodiments, since the closed cover 3 is only fixed at both ends, and the middle is not fixed, both sides of the closed cover are supported on the axial slide rail 101 or the base frame 1 On both sides of the closed cover, when the hardness of the closed cover itself cannot support its own weight, the middle of the closed cover will fall into the roasting tunnel and lose the effect of blocking dust. A support rod 302 is provided, and the two ends of the support rod are supported on both sides of the axial slide rail or the base frame, and the support rod can be a rod, strip or plate with a certain supporting strength such as steel bar or plastic. Support bar can utilize ropes such as iron wire to be fixed on the closure cover, and the distance of support bar interval is set according to the hardness of closure cover.

Embodiment 3

[0032] Such as Figure 7 As shown, on the basis of the second embodiment, a slot 102 is provided on both sides of the base frame 1. The opening diameter of the slot is smaller than the inner diameter of the slot. Blocks 303 are provided on both sides of the closure cover 3. The shape of the block is The cross-sectional shape is the same as that of the card slot. After the card block is inserted into the card slot, the card block cannot come out from the opening of the card slot but can slide in the card slot. The blocks are also arranged at intervals, so that when the hopper frame is moving, the blocks on both sides will contact or separate from each other, and the connected closing cover will be folded or unfolded to ensure the sealing of the pit mouth.

Abstract

The present invention discloses a filler dust eliminating apparatus used in a baking tunnel during a baking process of a graphite manufacturing process, and relates to the field of graphite manufacturing. The apparatus comprises a rectangular base frame and a hopper frame installed on the base frame. Both axial sides of the base frame are provided with axial slide rails. The bottom of the hopper frame contacts the axial slide rails by slide apparatuses. The middle parts between the hopper frame and the two axial ends of the base frame are respectively provided with a rectangular sealing cover. Both axial ends of the sealing covers are respectively fixed on the two edges of the hopper frame, wherein the two edges of the hopper frame are relative to the base frame. According to the scheme of the present invention, the hopper can freely move above the baking tunnel by the base frame, it is ensured that the filler formed by mixing metallurgical coke and quartz sand, or river sand and the like can be uniformly filled in any positions in the baking tunnel; the dust generated during the filler pouring process is prevented from diffusion into the air by the sealing cover on the base frame; with the sealing cover, the sealing of the tunnel mouth can be remained during the hopper frame moving process so as to prevent the diffusion of the dust to the maximal degree; with the dust discharge mouth on the base frame, the dust dissipation time in the tunnel can be shortened.

Description

technical field [0001] The invention relates to the field of graphite production, in particular to a device for eliminating and reducing dust generated when filling filling materials when formed carbonaceous raw materials are roasted in a roasting tunnel. Background technique [0002] In the existing graphite production process, the first roasting of carbonaceous raw materials after molding is a very important process. The specific process is to place the carbonaceous blocks made of shaped carbonaceous raw materials in the underground roasting tunnel for 1200-1500 minutes. The roasting tunnel includes open structures such as h4*d4 meters and h5.2*d6 meters, with a width of about 0.8 to 1.8 meters. Multiple side-by-side placements are often used, and the formed carbonaceous blocks are placed inside. Finally, there are gaps between each other, which need to be filled with fillers to prevent the carbonaceous blocks from toppling or deforming during the roasting process. The fil...
