Description

Technical Field

[0001] This utility model relates to the technical field of powder feeding equipment, specifically a powder conveying and feeding device. Background Technology

[0002] Carbon black powder is an amorphous carbon material with unique physicochemical properties and a wide range of applications. Its main component is carbon, containing small amounts of hydrogen, oxygen, sulfur, and other elements. It is characterized by fine particles, a well-developed pore structure, and a large specific surface area. It appears as a black powder, is insoluble in water and organic solvents, and possesses excellent coloring power, abrasion resistance, electrical conductivity, and adsorption properties. Typically, carbon black powder needs to be granulated using a granulator, dried, and then packaged for sale.

[0003] However, in the process of granulating carbon black powder using a granulator, the carbon black powder must first be conveyed upwards into the granulator. But because the carbon black powder particles are small and the conveying angle is large, traditional screw conveyors are unable to complete the conveying task. Therefore, there is an urgent need to design a new device to solve this problem. Utility Model Content

[0004] To address the existing problems, this utility model provides a powder conveying and feeding device to solve the problem mentioned in the background art that traditional screw conveyors are unable to complete the conveying task due to the small particle size of carbon black powder and the large conveying angle.

[0005] To address the existing problems, this utility model provides a powder conveying and feeding device, including a base plate, two parallel vertical frames fixedly connected to the upper surface of the base plate, a vertical conveying mechanism between the two vertical frames, and a receiving mechanism on one side of one of the vertical frames.

[0006] The conveying mechanism includes a sliding member slidably connected to one side of each of the vertical frames. One end of a connecting arm is rotatably connected to the sliding member. The other end of the connecting arm is fixedly connected to the side of a hopper. A U-shaped frame is fixedly connected to the upper end of the hopper. The lower ends of connecting wire ropes are fixedly connected to both ends and the middle of the U-shaped frame. The upper ends of the connecting wire ropes are fixedly connected to the winding wire rope end of the winch. The winch is fixedly connected to the upper end of the vertical frame via a mounting plate.

[0007] The receiving mechanism includes an extension arm fixedly connected to the side of one of the vertical frames. A receiving hopper is provided at the upper end of the extension arm. Sliding sleeves are fixedly connected to both sides of the receiving hopper. The sliding sleeves are slidably sleeved on a guide rod located at the upper end of the extension arm. One end of the guide rod is fixedly connected to the side of the vertical frame, and the other end of the guide rod is fixedly connected to the end of the extension arm away from the vertical frame through a connecting plate. A first fixing ear is fixedly connected to the bottom surface of the receiving hopper, and a second fixing ear is fixedly connected to the lower middle end of the extension arm. The first fixing ear and the second fixing ear are respectively hinged to the telescopic end and the fixed end of the first hydraulic cylinder.

[0008] Furthermore, a reinforcing rod is provided on the lower side of the extension arm, and the two ends of the reinforcing rod are fixed to the lower surface of the extension arm and the side of the vertical frame, respectively.

[0009] Furthermore, the sliding member includes a rotating shaft disposed on the side of the vertical frame, with pulleys rotatably connected to both ends of the rotating shaft, and the pulleys slidingly contacting the side edges of the vertical frame.

[0010] Furthermore, the bottom of the hopper is provided with two sealing plates. The two ends of the sealing plates that are far apart are hinged to the lower end of the side wall of the hopper. The side end of the sealing plate is hinged to the telescopic end of the second hydraulic cylinder. The fixed end of the second hydraulic cylinder is hinged to the side wall of the hopper.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention, by setting up a conveying mechanism and a receiving mechanism, allows the hoist of the conveying mechanism to lift the hopper filled with carbon black powder from the bottom of the vertical frame to the top of the vertical frame. Then, the first cylinder of the receiving mechanism is activated to push the receiving hopper towards the side closer to the vertical frame, so that the front end of the receiving hopper is below the bottom end of the hopper. Then, the second cylinder controls the sealing plate to open, and the carbon black powder in the hopper can fall from its bottom into the front end of the receiving hopper, and then flow directly from the rear end of the receiving hopper into the granulation equipment along the bottom plate of the receiving hopper, overcoming the shortcomings of existing auger conveying equipment.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-8 A powder conveying and feeding device includes a base plate 1, two parallel vertical frames 2 are fixedly connected to the upper surface of the base plate 1, a vertical conveying mechanism 3 is provided between the two vertical frames 2, and a receiving mechanism 4 is provided on one side of one of the vertical frames 2.

[0024] The conveying mechanism 3 includes a sliding member 301 slidably connected to one side of each vertical frame 2. One end of a connecting arm 302 is rotatably connected to the sliding member 301. The other end of the connecting arm 302 is fixedly connected to the side of a hopper 303. A U-shaped frame 304 is fixedly connected to the upper end of the hopper 303. The lower ends of connecting wire ropes 305 are fixedly connected to both ends and the middle of the U-shaped frame 304. The upper end of the connecting wire ropes 305 is fixedly connected to the winding wire rope end of the winch 306. The winch 306 is fixedly connected to the upper end of the vertical frame 2 through a mounting plate 307.

[0025] The receiving mechanism 4 includes an extension arm 401 fixedly connected to the side of one of the vertical frames 2. A receiving hopper 402 is provided at the upper end of the extension arm 401. Sliding sleeves 403 are fixedly connected to both sides of the receiving hopper 402. The sliding sleeves 403 are slidably sleeved on the guide rod 404 located at the upper end of the extension arm 401. One end of the guide rod 404 is fixedly connected to the side of the vertical frame 2. The other end of the guide rod 404 is fixedly connected to the end of the extension arm 401 away from the vertical frame 2 through a connecting plate 405. A first fixing ear 406 is fixedly connected to the bottom surface of the receiving hopper 402. A second fixing ear 407 is fixedly connected to the lower middle end of the extension arm 401. The first fixing ear 406 and the second fixing ear 407 are respectively hinged to the telescopic end and the fixed end of the first hydraulic cylinder 408.

[0026] It should be noted that the receiving hopper 402 is inclined relative to the horizontal plane, that is, the front end of the receiving hopper 402 is higher than the rear end. This ensures that the carbon black powder falling from the bottom of the hopper 303 can flow directly from the rear end of the receiving hopper 402 into the granulation equipment after flowing into the front end of the receiving hopper 402.

[0027] A reinforcing rod 5 is provided on the lower side of the extension arm 401, and the two ends of the reinforcing rod 5 are fixed to the lower surface of the extension arm 401 and the side of the vertical frame 2, respectively.

[0028] The sliding member 301 includes a rotating shaft 3011 disposed on the side of the vertical frame 2. The two ends of the rotating shaft 3011 are rotatably connected to pulleys 3012, and the pulleys 3012 slide in contact with the side edges of the vertical frame 2.

[0029] The bottom of the hopper 303 is provided with two sealing plates 3031. The two ends of the sealing plates 3031 that are far apart are hinged to the lower end of the side wall of the hopper 303. The side end of the sealing plate 3031 is hinged to the telescopic end of the second oil cylinder 3032. The fixed end of the second oil cylinder 3032 is hinged to the side wall of the hopper 303.

[0030] Working principle: In the initial state, the hopper 303 is located at the lowest end of the vertical frame 2. At this time, carbon black powder can be loaded into the hopper 303. After the hopper 303 is full, the winch 306 is controlled to work, so that the motor of the winch 306 drives the wire rope on the winding roller to wind and wind. The wound wire rope will pull the hopper 303 vertically upward by pulling the connecting wire rope 305 and the U-shaped frame 304. At this time, the stepped bosses of the two pulleys 3012 of the sliding part 301 will slide on the edge of the side of the vertical frame 2. When the hopper 303 is lifted to the top by the winch, it stops. At this time, the extension rod of the control cylinder 408 extends, which will push the receiving material. As the sliding sleeve 403 moves along the guide rod 404 towards the side closer to the vertical frame 2, the rear end of the receiving hopper 402 will be located below the two sealing plates 3031 at the bottom of the holding hopper 303. At this time, the extension rod of the control cylinder 3032 extends, which will drive the adjacent ends of the two sealing plates 3031 to rotate along the hinge between the sealing plates 3031 and the lower end of the side wall of the holding hopper 303. This will cause the carbon black powder inside the holding hopper 303 to fall to the front end of the receiving hopper 402. Since the receiving hopper 402 is inclined relative to the horizontal plane, the carbon black powder at the front end of the receiving hopper 402 will slide and fall from the rear end of the receiving hopper 402 into the granulation equipment.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model.
