Description

Technical Field

[0001] The utility model relates to the technical field of baking frames, in particular to a baking frame for producing carbon products. Background Art

[0002] In the production of carbon products (high-purity graphite), it has to go through the roasting process, especially the impregnated products have to be repeatedly impregnated and roasted. The traditional roasting frame is to put the impregnated products into the frame, and then use a crane to lift the frame into the roasting furnace for roasting. However, the bottom of the traditional roasting frame is a hollow structure. After the impregnation, there is a lot of asphalt inside and outside the product. During the roasting process, as the temperature rises, the asphalt migrates to the lower layer of the product, which will cause the product to crack and affect the product yield.

[0003] The Chinese utility model patent, authorization announcement number "CN 207395491 U", discloses a baking frame for carbon product production, which is composed of a frame, a closed bottom plate, a sawdust layer, a metallurgical coke layer and fixing parts. The baking frame has a simple structure and a reasonable design. The bottom is set to be closed to prevent asphalt from penetrating and flowing onto the lower layer of products, thereby improving the yield rate and having strong practicality.

[0004] The above solution still has certain problems in actual use. For example, since the metallurgical coke layer is in direct contact with the impregnated product, although the metallurgical coke layer can dilute the asphalt flowing down, the asphalt is still in contact with the bottom of the impregnated product at the bottom, which may also cause cracks in the product and affect the product yield. Utility Model Content

[0005] The purpose of the utility model is to provide a baking frame for producing carbon products to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a baking frame for producing carbon products, comprising a C-shaped bottom plate with an open top, both sides of the bottom plate are provided with hollow side plates, and the top ends of the side plates are fixed with symmetrically arranged hanging ears;

[0007] A bearing part that contacts the carbon product material at multiple points is arranged between the inner walls on both sides of the bottom plate, and the carbon product material is stacked and placed on the top of the bearing part;

[0008] A pull-out dilution component is provided on the inner wall at the bottom of the base plate. The dilution component is located below the bearing portion.

[0012] The two outermost connecting frames are respectively fixed to the inner walls on both sides of the bottom plate;

[0013] Both sides of the top of the connecting frame are formed with slopes to facilitate the downward flow of asphalt.

[0014] Preferably, the dilution layer includes a metallurgical coke layer and a sawdust layer, and the metallurgical coke layer is located above the sawdust layer.

[0015] Preferably, the distance between the bearing portion and the dilution component is 0.5-5 cm.

[0016] Preferably, a second fixed shaft and an inclined plate are fixed on both sides of the front side of the bottom plate, and a baffle is movably connected to the shaft body of the second fixed shaft;

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] The roasting frame for the production of carbon products is provided with a bearing portion that contacts the material at multiple points. During the roasting process, the produced asphalt flows downward along the bearing portion and then falls to the top of the dilution component. In this way, since the bearing portion contacts the material at multiple points and the contact area with the material is small, the contact area between the asphalt remaining on the top of the bearing portion and the material at the bottom is small, which can minimize the contact between the asphalt and the material, effectively prevent the product from cracking, and improve the product yield.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] This baking frame is used for the production of carbon products (high purity graphite) to obtain purer and higher quality graphite materials.

[0029] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a baking frame for carbon product production, comprising a C-shaped bottom plate 1 with an open top, and hollow side plates 2 are arranged on both sides of the bottom plate 1. The hollow setting of the side plates 2 can not only reduce the overall weight of the baking frame, but also save material costs. A symmetrically arranged lifting lug 3 is fixed on the top of the side plate 2, and a crane lifts the frame into a baking furnace through the lifting lug 3 for baking;

[0030] A bearing part 4 is provided between the inner walls on both sides of the bottom plate 1, and the contact structure between the bearing part 4 and the material can be a cone, needle or other shape with the top in point contact. It can be known that the material (impregnated product) is stacked and placed on the top of the bearing part 4, and a dilution component 5 that can be pulled out is provided on the inner wall at the bottom of the bottom plate 1, such as Figure 4 As shown, the dilution component 5 includes a frame 501 sliding on the bottom plate 1, and a dilution layer for diluting the asphalt produced after the material is roasted is arranged inside the frame.

[0031] In order to facilitate the placement of carbon product materials and the removal of materials after roasting, a rotating part is provided between the bottom plate 1 and the side plate 2. Figure 1As shown, the rotating part includes a fixed rod 602 and a connecting shaft arranged on the side of the base plate 1, the side plate 2 is movably connected to the connecting shaft, and a first fixed shaft 601 is fixed on the side of the side plate 2 and the top of the base plate 1, and the two sides of the fixed rod 602 are movably connected with the two first fixed shafts 601 respectively.

[0032] Specifically, after the material is placed, the side plate 2 is rotated until the side plate 2 and the bottom plate 1 are perpendicular to each other, and then the circular holes on both sides of the fixing rod 602 are inserted into the first fixing shaft 601 to position the side plate 2, which is convenient for the crane to lift the roasting frame.

[0033] like Figure 1 and Figure 4 As shown, the bearing portion 4 includes a plurality of conical platforms 401 distributed in a matrix, and the lateral conical platforms 401 are fixed by connecting frames 402. It can be known that the two outermost connecting frames 402 are respectively fixed to the inner walls of the two sides of the bottom plate 1;

[0034] In addition, slopes 403 are formed on both sides of the top of the connecting frame 402 to facilitate the downward flow of asphalt.

[0035] Specifically, during the roasting process, the asphalt produced flows downward along the body of the conical table 401 and the connecting frame 402, and then falls to the top of the dilution component 5. In this way, since the contact area between the top of the conical table 401 and the material is smaller, the contact area between the asphalt remaining on the top of the conical table 401 and the material at the bottom is small, that is, the contact between the asphalt and the material can be minimized, effectively preventing the product from cracking and improving the product yield. It should be noted that the conical table 401 can be replaced by other geometric structures such as a truncated cone, a needle-shaped structure, etc., which have the same effect.

[0036] like Figure 4 As shown, the dilution layer includes a metallurgical coke layer 502 and a sawdust layer. The metallurgical coke layer 502 is located above the sawdust layer. The metallurgical coke layer 502 and the sawdust layer can be replaced by other material layers with similar functions.

[0037] In order to reduce the accumulation of asphalt at the bottom of the bearing part 4, in a specific embodiment of the present solution, the distance between the bearing part 4 and the dilution assembly 5 is 4 cm.

[0038] To facilitate fixing the frame 501, Figure 1 and Figure 3 As shown, a second fixed shaft 701 and an inclined plate 703 are fixed on both sides of the front side of the base plate 1, and a baffle 702 is movably connected to the shaft body of the second fixed shaft 701. In addition, in order to facilitate the disassembly and assembly of the frame 501, magnet plates 704 that attract each other are fixed on the top of the inclined plate 703 and the left side of the baffle 702.

[0039] Specifically, after the frame 501 is inserted into the bottom plate 1, the baffle 702 is rotated so that the inner side of the baffle 702 contacts the surface of the frame 501 to achieve longitudinal positioning of the frame 501. When the frame 501 is disassembled and assembled, and the metallurgical coke layer 502 and the sawdust layer are replaced, Figure 3 As shown, the baffle 702 is rotated clockwise until the two magnets of the baffle 702 and the inclined plate 703 are attracted to each other, thereby limiting the position of the baffle 702 and facilitating the pulling out of the frame body 501.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
