In specific implementation, dry materials for preparing artificial graphite are added into the first feeding box 110 along the first feeding pipe 140, the exhaust fan 200 and the conveying belt 120 are operated at the same time, the dry materials fall layer by layer through the plurality of guide plates 150 after entering the first feeding box 110, and powder materials and particle materials in the dry materials are respectively conveyed through different conveying lines in the falling process; by arranging the material guide plate 150, the falling time of the dry materials in the first feeding box 110 can be prolonged, and then the powder and the granular materials in the dry materials can be separated to the maximum; in the concrete transportation process, the powder conveying line is as follows: under the action of the exhaust fan 200, the powder material passes through the first filter screen 170 and is then conveyed to the second filter screen 210 along the air box 180 and the first air pipe 190, and the aperture of the filter hole of the second filter screen 210 is smaller than that of the first filter screen 170, so that the powder material conveyed to the second filter screen 210 is blocked, and then falls into the powder material pipe 220 under the action of gravity and then falls into the kneading box 130 under the action of gravity; because the second filter screen 210 blocks the powder, the gas discharged along the second air duct 300 does not contain the powder, so that the environment is not polluted and the powder is not wasted; the granule conveying line comprises: the granules are discharged through the discharge port 160 of the first feeding box 110, fall onto the conveying belt 120 under the action of gravity, and are sequentially conveyed into the feed port of the kneading box 130 through the conveying belt 120, so that the granules are completely conveyed into the kneading box 130. By conveying the powder and the granules in the dry material through different conveying lines, the maximum conveying of the powder and the granules to the kneading box 130 can be ensured, the defect of powder loss in the traditional conveying process is overcome, and the yield of the artificial graphite are ensured.
Further, in order to enable the conveying device to simultaneously meet the requirement of conveying the dry materials and the adhesive, as shown in fig. 1 and 2, a second feeding box 230 with an opening at the bottom is further disposed at the inner top of the housing 100, and the second feeding box 230 is disposed right above the conveying belt 120, so that the adhesive can smoothly fall onto the conveying belt 120 from the opening; in addition, the top of the second feeding box 230 is communicated with a second feeding pipe 310 for the introduction of the adhesive; because the viscosity of the adhesive is very high, the adhesive is often bonded together to form a large block of material, and if the adhesive is directly conveyed along the conveying belt 120, the large block of adhesive and the dry material are difficult to be uniformly mixed, so that the operation difficulty is improved; in order to overcome the defect, a central shaft 240 is coaxially arranged inside the second feeding box 230, the top of the central shaft 240 penetrates through the top of the casing 100 and is fixedly connected with the output end of a motor 250 arranged right above the casing 100, and a plurality of blades 260 are arranged on the outer wall of the central shaft 240. In specific implementation, the adhesive is fed into the second feeding box 230 along the second feeding pipe 310, and the motor 250 is turned on, so that the central shaft 240 and the plurality of blades 260 rotate under the action of the motor 250, and the blades 260 cut and break the adhesive, so that the large adhesive is dispersed into small blocks, and then the small blocks fall onto the conveying belt 120 along the bottom opening of the second feeding box 230 and are conveyed into the kneading box 130 through the conveying belt 120. The adhesive is dispersed into a plurality of small blocks, so that the contact area between the adhesive and the granular materials on the conveying belt 120 can be increased, and the contact area between the adhesive and the dry materials in the kneading box 130 can also be increased, thereby improving the mixing efficiency of the adhesive and the dry materials in the kneading box 130.
Further, in the conveying process of the conveying belt 120, if the length of the discharge port 160 is shorter than the width of the conveying belt 120, a part of the materials are difficult to enter the kneading box 130, and the materials are wasted, in order to overcome the defect, as shown in fig. 2, a funnel 270 matched with the conveying belt 120 is communicated with the top of the discharge port 160, the top surface of the funnel 270 is rectangular, and the length of the top surface of the funnel 270 is greater than the width of the conveying belt 120. Through the funnel 270 that sets up top surface and transmission band 120 looks adaptation, can make on the transmission band 120 all materials homoenergetic get into in the funnel 270, and then avoid the material extravagant.
Further, if the distance between the top surface of the funnel 270 and the conveyor 120 is relatively long, a portion of the material is still difficult to enter the funnel 270 because the material is scattered during the falling process, and for this reason, as shown in fig. 1, the top of the funnel 270 near the first feeding box 110 abuts against the surface of the conveyor 120. By abutting the top surface of the funnel 270 against the surface of the transmission belt 120, the straight material sections on the transmission belt 120 can fall into the funnel 270 from the transmission belt 120 without hanging to fall, so that the loss caused by the scattering of the material is avoided; meanwhile, by abutting the top surface of the funnel 270 against the surface of the transmission belt 120, the adhesive adhered to the surface of the transmission belt 120 can be scraped off by the top surface of the funnel 270, and all the materials are ensured to enter the kneading box 130.
Further, as shown in fig. 1, the bottom of the first feeding box 110 is disposed obliquely downward toward the conveying belt 120. The inclined arrangement enables the granules at the bottom of the first feeding box 110 to smoothly slide to the discharging port 160, thereby reducing the residue of the granules at the bottom of the first feeding pipe 140.
Further, as shown in fig. 1 and fig. 3, the discharge end of the discharge hole 160 is provided with a guide belt 280 which is obliquely arranged downwards, so as to smoothly guide the granular materials onto the conveyor belt 120; the bottom end of the material guide belt 280 abuts against the top surface of the transmission belt 120, and the material guide belt 280 is made of a flexible material, so that friction between the material guide belt 280 and the transmission belt 120 can be reduced. Through setting up the material guide belt 280 can effectively dredge through discharge gate 160 exhaust granule material, make the granule material along material guide belt 280 landing to transmission band 120 on, reduce the granule material and transmit to the transmission band 120 after the emergence bounce spatters the phenomenon, and then reduce the loss of granule material.
Further, as shown in fig. 1 and fig. 2, baffles 290 are arranged on two sides of the top surface of the conveying belt 120, and by arranging the baffles 290, the materials on the conveying belt 120 can be effectively blocked, so that the materials are prevented from falling along the edge of the conveying belt 120, and material loss is avoided.
Further, as shown in fig. 1, the top of the first filter 170 is higher than the center of the uppermost guide plate 150, and the bottom of the first filter 170 is lower than the center of the lowermost guide plate 150. With the arrangement, the powder in the first feeding box 110 can be fully pumped out, so that the residue of the powder in the first feeding box 110 is reduced, and the yield of the artificial graphite is ensured.
