Description

Technical Field

[0001] This utility model relates to the technical field of paste-adding equipment for calcium carbide furnaces, and specifically to an automatic paste-adding device for calcium carbide furnaces. Background Technology

[0002] Calcium carbide is an important chemical raw material widely used in industrial production. The core of the calcium carbide production system is the electrode system. The three-phase electrodes convert electrical energy from the transformer into heat energy to fuel the reaction of raw materials in the furnace to produce calcium carbide. During operation, the electrodes are continuously consumed, requiring periodic replenishment of electrode paste from the fifth floor of the calcium carbide furnace. The electrode paste storage hopper is located on the first floor of the furnace. The electrode paste is manually unloaded from the hopper into a hopper using a vibrating feeder. The hopper is then manually pushed to the hoisting opening on the first floor, and an overhead crane lifts the hopper to the fifth floor. Finally, the overhead crane adds the electrode paste into the electrode cylinder.

[0003] During the hoisting process, accidents are prone to occur. Therefore, inclined conveyor belts are often used to transport the electrode paste. However, during the rotation of the conveyor belt, a small amount of electrode paste adheres to the lower end. This electrode paste easily falls off due to its own weight during transport, and the lack of corresponding collection devices makes it difficult to recycle the fallen electrode paste mixed with dust on the ground. If the electrode paste is contaminated with a large amount of dust, the ash content will increase, and the adhesion will deteriorate, potentially causing a series of problems. For example, improper storage of electrode paste contaminated with dust can lead to increased ash content and poor adhesion, potentially causing electrode problems. Furthermore, dust in the electrode paste may affect electrode sintering and consumption, increasing the risk of electrode accidents. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic paste-adding device for a calcium carbide furnace, which solves the problem that the electrode paste is easily dropped during the conveyor belt at the lower end due to its own gravity, and the lack of a corresponding collection device makes it difficult to recycle the dropped electrode paste mixed with dust on the ground.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An automatic paste-adding device for a calcium carbide furnace includes a frame that slopes downwards from left to right. A conveyor belt is installed within the frame. A motor for driving the conveyor belt is located on the left side of the frame. A hopper is located on the right side of the frame, above the starting end of the conveyor belt. The discharge port at the bottom of the hopper faces the conveyor belt. Multiple equally spaced partitions are provided on the conveying end face of the conveyor belt. Multiple support legs are provided on both sides of the frame. Support legs on the same side of the frame are connected to horizontally arranged support rods. A collection frame slides on the support rods on both sides of the frame. A guide plate, inclined downwards from left to right, is located at the lower left end of the frame. The lower end of the guide plate faces the collection frame, and the right end of the guide plate is located above the collection frame.

[0007] A further technical solution is that two parallel support plates are vertically connected to the two support rods, and each support plate is provided with a first limiting plate along its length. The two first limiting plates and the two support plates form a sliding groove for the collection frame to slide.

[0008] A further technical solution is to provide second limiting plates on both sides along the length direction of the upper end of the guide plate, and the right ends of the two second limiting plates are respectively connected to the two sides of the middle part of the frame through two guide rods.

[0009] A further technical solution is that the inner side of the frame is provided with a support frame for supporting the conveyor belt, and a drive roller and a transmission roller are respectively provided on the left and right sides of the support frame. The drive roller and the transmission roller are rotatably arranged inside the frame. The drive roller and the transmission roller are each provided with a pusher toothed disc that meshes with the inner side of the conveyor belt. The motor is connected to the drive roller through a reducer.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] The electrode paste is added to the hopper and then conveyed to the left side of the frame via a conveyor belt. During this process, some electrode paste adheres to the conveyor belt as it passes the left side of the frame. As the conveyor belt continues to rotate, the adhered electrode paste falls down onto the guide plate due to its own gravity. The guide plate then discharges the fallen electrode paste into the collection box for collection, preventing it from falling to the ground and mixing with dust. The electrode paste collected in the collection box can also be recycled. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] Example:

[0016] refer to Figures 1 to 2 As shown, an automatic paste-adding device for a calcium carbide furnace is disclosed, including a frame 1 that is higher on the left and lower on the right. A conveyor belt 2 is installed inside the frame 1. A motor 3 for driving the conveyor belt 2 is installed on the left side of the frame 1. A hopper 4 is installed on the right side of the frame 1 and above the conveying end of the conveyor belt 2. The discharge port at the bottom of the hopper 4 faces the conveyor belt 2. Multiple partitions 5 are evenly distributed on the conveying end face of the conveyor belt 2. Multiple support feet 6 are provided on both sides of the frame 1. The support feet 6 on the same side of the frame 1 are connected to horizontally arranged support rods 7. A collection frame 8 is slidably installed on the support rods 7 on both sides of the frame 1. A guide plate 9 is provided at the lower left side of the frame 1, which is inclined downward from left to right. The lower end of the guide plate 9 faces the collection frame 8, and the right end of the guide plate 9 is located above the collection frame 8.

[0017] In this invention, the electrode paste to be added is added into the hopper 4, and then conveyed to the left side of the frame 1 by the conveyor belt 2. During this process, after the conveyor belt 2 passes the left side of the frame 1, some of the electrode paste will adhere to the conveyor belt 2. As the conveyor belt 2 continues to rotate, the adhered electrode paste will fall down onto the guide plate 9 due to its own gravity. The guide plate 9 will then discharge the fallen electrode paste into the collection box 8 for collection, thus preventing the electrode paste from falling to the ground and mixing with the dust on the ground. The electrode paste collected in the collection box 8 can also be recycled and reused.

[0018] By controlling the operation of motor 3, the purpose of automatically conveying the electrode paste can be achieved.

[0019] Two parallel support plates 10 are vertically connected to the two support rods 7. Each support plate 10 is provided with a first limiting plate 11 along its length. The two first limiting plates 11 and the two support plates 10 form a sliding groove for the collection frame 8 to slide. The setting of the two first limiting plates 11 facilitates the sliding limitation of the collection frame 8, which is conducive to the linear sliding of the collection frame 8 on the two support plates 10.

[0020] A second limiting plate 12 is provided on both sides along the length direction of the upper end of the guide plate 9. The right ends of the two second limiting plates 12 are respectively connected to the two sides of the middle part of the frame 1 through two guide rods 13. The setting of the second limiting plate 12 helps to prevent the electrode paste from sliding off the side of the guide plate 9 when it slides on the guide plate 9.

[0021] The inner side of the frame 1 is provided with a support frame 14 for supporting the conveyor belt 2. A drive roller 15 and a transmission roller 16 are respectively provided on the left and right sides of the support frame 14. Both the drive roller 15 and the transmission roller 16 are rotatably mounted inside the frame 1. Each drive roller 15 and the transmission roller 16 is provided with a pusher toothed disc 17 that meshes with and is connected to the inner side of the conveyor belt 2. The motor 3 is connected to the drive roller 15 through a reducer 18, and provides support for the conveyor belt 2 through the support frame 14. (See reference for details.) Figure 2 As shown, the conveyor end facing upwards is supported. The motor 3 drives the drive roller 15 to rotate through the reducer 18. During the rotation of the drive roller 15, the push toothed disc 17 is driven to rotate, and then the push toothed disc 17 drives the conveyor belt 2 to rotate.

[0022] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of the disclosure, drawings, and claims. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
