Description

Technical Field

[0001] This utility model relates to the field of graphitization furnaces, specifically a device for compacting bottom carbon black in graphitization furnaces, which is particularly suitable for rapid and efficient compaction of bottom carbon black during furnace loading in graphitization furnaces. Background Technology

[0002] In the graphitization furnace production process, a layer of carbon black needs to be laid at the bottom of the furnace as an insulation and heat preservation medium, which requires the carbon black to be compacted.

[0003] Traditional compaction methods often rely on manual spreading or mechanical vibration to achieve compaction, which suffers from low efficiency, high cost, and poor compaction uniformity. Existing technologies using briquetting equipment require an additional power source and are difficult to adapt to the complex spatial structure of the furnace bottom, resulting in low equipment utilization and maintenance difficulties. Utility Model Content

[0004] To achieve the above objectives, the present invention aims to provide a device for compacting carbon black at the bottom of a graphitization furnace. This device has a simple structure, requires no external power, and utilizes its own weight to achieve efficient compaction of carbon black, significantly reducing energy consumption and labor costs. Through modular design and overhead crane operation, it significantly improves compaction efficiency and uniformity, making it particularly suitable for large-scale graphitization furnace production. The present invention provides the following technical solution:

[0005] An apparatus for compacting carbon black at the bottom of a graphitization furnace includes a frame, a lifting assembly, and filler. The frame comprises multiple protective plates forming a cuboid shell. The filler is placed inside the frame, and a base plate is installed at the bottom of the frame. The lifting assembly includes four hooks symmetrically installed at the four corners of the top of the frame. The working process of this product is as follows:

[0006] Lifting and positioning: Use an overhead crane to lift the product to the top of the graphitization furnace and adjust it to the center of the carbon black laying area;

[0007] Gravity compaction: Slowly lower this product onto the surface of the carbon black layer and let it stand for 10-15 minutes to use the weight of this product to evenly compact the carbon black.

[0008] Repeated operation: According to the required thickness of carbon black, fill the material in layers and compact it repeatedly. After each compaction, the density of carbon black will increase by no less than 30%.

[0009] As a further embodiment of this utility model: the guard plate is made of Q235B steel plate and the frame is welded from the guard plate. The dimensions of the frame are 1.5m long × 1.2m wide × 1.2m high.

[0010] As a further embodiment of this utility model: the filling material is concrete, and the filling ratio of the filling material is 85%-90% of the frame volume, so that the overall self-weight can reach more than 6 tons, avoiding insufficient counterweight or material waste. Steel fibers can also be mixed into the concrete, and the volume of the steel fibers is 1.5% of the concrete volume.

[0011] As a further embodiment of this utility model: the thickness of the protective plate is not less than 10mm, and the surface roughness Ra of the base plate is not greater than 3.2μm, to ensure uniform contact with the carbon black layer.

[0012] As a further embodiment of this utility model, an anti-slip buckle is installed on the inner side of the hook to prevent the hook from accidentally slipping off during the hoisting process and to ensure safety during use.

[0013] As a further embodiment of this utility model, the hook is made of alloy steel, and the tensile strength of the alloy steel is not less than 500MPa.

[0014] As a further embodiment of this utility model: the distance between the center and the edge of the hook is not less than 200mm, which is suitable for overhead crane hoisting.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This product achieves non-powered compaction through its own weight, reducing energy consumption by 100% and increasing compaction efficiency by more than 2 times.

[0017] This product features a modular design, making it compatible with various furnace types. The flat base plate ensures uniform carbon black layer density with a deviation of no more than 5%.

[0018] This product is easy to hoist and can be completed by a single person, reducing labor costs by 70%. Attached Figure Description

[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] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] Please see Figures 1-2 This utility model provides a device for compacting carbon black at the bottom of a graphitization furnace, comprising a frame, a lifting assembly, and a filler 2. The frame includes multiple protective plates 1 forming a cuboid shell. The filler 2 is placed inside the frame, and a bottom plate 4 is installed at the bottom of the frame. The bottom plate 4 can compact the carbon black. The lifting assembly includes four hooks 3 symmetrically installed at the four corners of the top of the frame. The installation position of the hooks 3 has been verified by finite element analysis to ensure uniform lifting force. The working process of this product is as follows:

[0025] Lifting and positioning: Use an overhead crane to lift the product to the top of the graphitization furnace and adjust it to the center of the carbon black laying area, with a height of no more than 0.5m from the carbon black material surface;

[0026] Gravity compaction: Slowly lower this product onto the surface of the carbon black layer and let it stand for 10-15 minutes. Use the weight of this product to compact the carbon black evenly. After standing, lift the product and check the density of the carbon black layer.

[0027] Repeated operation: According to the required thickness of carbon black, fill the material in layers and compact it repeatedly. After each compaction, the carbon black density will increase by no less than 30% until the carbon black layer reaches the required thickness (usually 200-300mm).

[0028] In one embodiment of this utility model, the protective plate 1 is made of Q235B steel plate and the frame is welded from the protective plate 1. It has good wear resistance and long service life. The dimensions of the frame are 1.5m long × 1.2m wide × 1.2m high.

[0029] In one embodiment of this utility model, the filler 2 is made of concrete, preferably C30 concrete. The filling ratio of the filler 2 is 85%-90% of the frame volume, so that the overall self-weight can reach more than 6 tons, avoiding insufficient counterweight or material waste. Steel fibers can also be mixed into the concrete, with the volume of steel fibers being 1.5% of the concrete volume, to enhance the overall crack resistance of the filler 2. Combined with the base plate 4 made of detachable wear-resistant plate (such as Mn13 steel plate), the life of the device is extended to more than 5 years. At this time, concrete is poured in the frame first, and after curing for 28 days, the hook 3 and the base plate 4 are installed.

[0030] In one embodiment of this utility model, the thickness of the protective plate 1 is not less than 10mm, and the surface roughness Ra of the base plate 4 is not greater than 3.2μm, to ensure uniform contact with the carbon black layer.

[0031] In one embodiment of this utility model, an anti-slip buckle is installed on the inner side of the hook 3 to prevent the hook 3 from accidentally slipping off during the hoisting process and to ensure safety during use.

[0032] In one embodiment of this utility model, the hook 3 is made of alloy steel, and the tensile strength of the alloy steel is not less than 500MPa.

[0033] In one embodiment of this utility model, the distance between the center and the edge of the hook 3 is not less than 200mm, which is suitable for crane hoisting.
