Description

Technical Field

[0001] This utility model relates to the field of electrode paste production technology, and in particular to a carbon electrode paste material conveying device. Background Technology

[0002] Carbon electrode paste is a core conductive material in high-temperature smelting equipment such as electric arc furnaces and calcium carbide furnaces. It is mainly made from raw materials such as anthracite, coke and pitch through kneading. Its function is to form conductive columns through self-baking, introduce current into the furnace to generate an electric arc, and maintain a high-temperature reaction environment above 2000℃. In the process from kneading to molding, the paste needs to be transferred by a conveying device to achieve safe and efficient transportation of the paste from the kneading pot to the molding equipment.

[0003] In existing technologies, the receiving hopper and the lifting device are mostly designed as separate units. The lifting device is usually set below the mixing tank. When the receiving trolley moves to the bottom of the mixing tank, the lifting device lifts the trolley to receive the paste. However, the separate structure is prone to causing the center of gravity of the trolley to shift, which can easily lead to the risk of tipping over when receiving the material. At the same time, during the receiving and transportation process, the vibration of the trolley can easily cause material to spill, which not only pollutes the environment but also increases the loss of raw materials. Utility Model Content

[0004] The purpose of this invention is to provide a carbon electrode paste receiving device. By integrating the receiving hopper with the lifting device, the device can maintain a stable center of gravity and improve the stability of the receiving process.

[0005] To achieve the above objectives, a carbon electrode paste receiving device is provided. The carbon electrode paste receiving device includes: a base, a motor fixedly connected to the left surface of the base, a bidirectional screw fixedly connected to the output end of the motor, a support block threadedly connected to the outer surface of the bidirectional screw, a scissor-type lifting arm provided at the upper end of the support block, a slider provided at the upper end of the scissor-type lifting arm, and a hopper slidably connected to the top of the slider.

[0006] A guide rod is fixedly connected to the upper surface of the base. A lifting block is fixedly connected to the upper end of the guide rod. A connecting rod is rotatably connected to the upper end of the lifting block. A connecting seat is rotatably connected to the end of the connecting rod away from the lifting block. A material cover is fixedly connected to the upper surface of the connecting seat. A sliding groove is provided on the material cover. A limit rod is slidably connected to the inner surface of the sliding groove.

[0007] According to the carbon electrode paste conveying device, a synchronous wheel is fixedly connected to the right end of the bidirectional screw. The synchronous wheels are driven by a synchronous belt, which facilitates the connection of the two bidirectional screws and realizes the synchronous rotation of the two bidirectional screws, thereby achieving synchronous adjustment of the two scissor lifts and ensuring the stability of the hopper lifting.

[0008] According to the carbon electrode paste conveying device, fixed seats are fixedly connected to the left and right sides of the hopper, and a rotating shaft is rotatably connected to the inner surface of the fixed seat. Moving wheels are fixedly connected to both ends of the rotating shaft, which facilitates the support of the hopper, makes it convenient for the hopper to move and transfer the paste, and can also separate from the ground when the hopper is raised, thereby improving the stability of the support for the base.

[0009] According to the carbon electrode paste conveying device, guide grooves are provided on the front and rear sides of the hopper. The inner surface of the guide groove is slidably connected to the lifting block, which facilitates the guidance of the movement of the lifting block, improves the stability of the movement of the lifting block, and thus improves the stability of the movement of the material cover.

[0010] According to the carbon electrode paste conveying device, limit seats are provided on the front and rear sides of the hopper. The inner surface of the limit seats is slidably connected to the guide rod, which facilitates the guidance and restriction of the lifting and lowering of the hopper and ensures the stability of the lifting and lowering direction of the hopper.

[0011] According to the carbon electrode paste receiving device, the lower surface of the base is fixedly connected with a bracket, and the bracket consists of four brackets arranged in a rectangular array.

[0012] According to the carbon electrode paste conveying device, the outer surface of the bidirectional screw is rotatably connected to the base, and the outer surface of the support block is slidably connected to the base.

[0013] According to the carbon electrode paste conveying device, the two ends of the limiting rod are fixedly connected to the hopper, which facilitates the support of the material cover and provides support for the movement of the material cover.

[0014] The above-mentioned solution has the following beneficial effects:

[0015] 1. By integrating the receiving hopper with the lifting device, the trolley can be prevented from deviating from the center of gravity of the lifting device when moving, thereby maintaining the stability of the device's center of gravity, improving the stability of the receiving process, and preventing the hopper from tipping over.

[0016] 2. During the lifting and lowering of the hopper, the guide rod drives the lifting block to move, which in turn drives the rear cover plate to move via the connecting rod. This causes the cover to automatically open when the hopper rises to the receiving position and close when it descends to the bottom, achieving a fully enclosed process for receiving and transporting the paste. This reduces material spillage, environmental pollution, and losses.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Reference Figure 1-4The present invention relates to a carbon electrode paste conveying device, comprising: a base 1, with four supports 22 fixedly connected to the lower surface of the base 1 in a rectangular array; a motor 2 fixedly connected to the left surface of the base 1; a bidirectional screw 3 fixedly connected to the output end of the motor 2; the outer surface of the bidirectional screw 3 being rotatably connected to the base 1; and a synchronous pulley 15 fixedly connected to the right end of the bidirectional screw 3. The synchronous pulleys 15 are driven by a synchronous belt 16. The synchronous pulleys 15 and the synchronous belt 16 are provided with meshing teeth to facilitate the connection of two bidirectional screws 3, achieving synchronous rotation of the two bidirectional screws 3, thereby enabling synchronous rotation of the two scissor lift arms 5. The step adjustment ensures the stability of the lifting of the hopper 7. The outer surface of the bidirectional screw 3 is threaded with a support block 4. The outer surface of the support block 4 is slidably connected to the base 1. The upper end of the support block 4 is provided with a scissor-type lifting arm 5. The upper end of the scissor-type lifting arm 5 is provided with a slider 6. The top of the slider 6 is slidably connected to the hopper 7. The left and right sides of the hopper 7 are fixedly connected with fixed seats 17. The inner surface of the fixed seats 17 is rotatably connected with a rotating shaft 18. The two ends of the rotating shaft 18 are fixedly connected with moving wheels 19, which facilitates the support of the hopper 7 and the movement of the hopper 7 to transfer the paste. At the same time, it can separate from the ground when the hopper 7 is raised, improving the stability of the support of the bracket 22 on the base 1.

[0027] A guide rod 8 is fixedly connected to the upper surface of the base 1. Limit seats 21 are provided on the front and rear sides of the hopper 7. The inner surface of the limit seat 21 is slidably connected to the guide rod 8, which facilitates the guidance and restriction of the lifting and lowering of the hopper 7 by the guide rod 8, ensuring the stability of the lifting and lowering direction of the hopper 7. A lifting block 9 is fixedly connected to the upper end of the guide rod 8. Guide grooves 20 are provided on the front and rear sides of the hopper 7. The inner surface of the guide groove 20 is slidably connected to the lifting block 9, which facilitates the guidance of the movement of the lifting block 9, improves the stability of the movement of the lifting block 9, and thus improves the stability of the movement of the material cover 12. A connecting rod 10 is rotatably connected to the upper end of the lifting block 9. A connecting seat 11 is rotatably connected to the end of the connecting rod 10 away from the lifting block 9. A material cover 12 is fixedly connected to the upper surface of the connecting seat 11. A sliding groove 13 is provided on the material cover 12. A limit rod 14 is slidably connected to the inner surface of the sliding groove 13. The two ends of the limit rod 14 are fixedly connected to the hopper 7, which facilitates the support of the material cover 12 and provides support for the movement of the material cover 12.

[0028] Working principle: When in use, the device is moved to the bottom of the mixing tank via the bottom moving wheels 19. The motor 2 drives the bidirectional screw 3 to rotate, causing the support blocks 4 on both sides to move towards each other. This, in turn, drives the slider 6 to move upward through the scissor-type lifting arm 5, thereby raising the hopper 7. During the upward movement of the hopper 7, the lifting block 9 moves downward along the guide groove 20 under the action of the guide rod 8. This, in turn, drives the material cover 12 to move through the connection of the connecting rod 10. The material cover 12 moves and flips open while moving through the connection of the sliding groove 13 and the limiting rod 14, making it easy to collect the paste. After collection, the motor 2 drives the bidirectional screw 3 to reverse and move the hopper 7 downward. Under the action of the guide rod 8, the lifting block 9 moves upward, thereby causing the two material covers 12 to flip and close, sealing the hopper 7.
