Novel crucible for roasting carbon products

Abstract

The utility model belongs to the technical field of carbon heat treatment, particularly relates to a novel crucible for roasting carbon products, and aims to solve the problems that most of existing carbon manufacturers isolate oxygen in the form of fillers, but pouring out or negative pressure sucking out of the fillers consumes a lot of time when the carbon products are discharged from a furnace, and meanwhile, the products are damaged by collision. According to the technical scheme, the roasting device comprises a first crucible wall and a second crucible wall which can be spliced to form a complete cavity, and the outer side of the first crucible wall and the outer side of the second crucible wall are provided with an upper limiting piece and a lower limiting piece which are used for limiting separation. And the discharge time and the collision damage of the carbon product can be effectively reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of carbon heat treatment, in particular to a crucible for roasting a new type of carbon product. Background Art

[0002] Special graphite mainly refers to high-strength, high-density, and high-purity graphite products (referred to as three-high graphite for short), which have excellent high-temperature resistance, electrical and thermal conductivity, lubricity, high-temperature characteristics, chemical corrosion resistance, high-temperature thermal spalling resistance, plasticity, etc. They are important functional and consumable materials and are widely used in industries such as smelting, molds, and chemicals. Although special graphite has many excellent properties, it is also difficult to produce finished products with large specifications. Especially in the key process - roasting. The roasting process is actually a process of heat-treating the green body to carbonize the binder into binder coke. The pressed green body is placed in a roasting furnace to undergo a series of physical and chemical reactions, and a binder coke film with a certain thickness is formed on the surface of the carbon aggregate, so that the product has a certain mechanical strength and physical and chemical properties as a whole.

[0003] During the roasting process, the green body needs to be in an oxygen-free environment. Most carbon manufacturers isolate oxygen in the form of fillers. However, when discharging from the furnace, pouring out or sucking out the fillers under negative pressure both consume a lot of time and can also cause damage to the product. Content of the Utility Model

[0004] The utility model provides a crucible for roasting a new type of carbon product, which solves the disadvantages in the prior art that most carbon manufacturers isolate oxygen in the form of fillers, but when discharging from the furnace, pouring out or sucking out the fillers under negative pressure both consume a lot of time and can also cause damage to the product.

At the bottom of the first crucible wall 1 and the second crucible wall 2, there are multiple layers of bottom plates that are inserted and interlocked with each other. At the bottom of the first crucible wall 1, a first insertion plate 11 and a second insertion plate 9 are integrally provided. At the bottom of the second crucible wall 2, a third insertion plate 12 and a fourth insertion plate 10 are integrally provided. There is an insertion spacing between the first insertion plate 11 and the second insertion plate 9, and there is an insertion spacing between the third insertion plate 12 and the fourth insertion plate 10. The first insertion plate 11, the second insertion plate 9, the third insertion plate 12, and the fourth insertion plate 10 are all circular, and the first insertion plate 11, the second insertion plate 9, the third insertion plate 12, the fourth insertion plate 10, and the spacing thickness are all equal;

[0029] At the lower side of the outer walls of the first crucible wall 1 and the second crucible wall 2, pulling ears are fixed. The pulling ears include an L-shaped main body 8. On both sides of the L-shaped main body 8, reinforcing plates 7 are fixed. Between the reinforcing plates 7, a pull rod 6 is fixed. The connecting rod 3 and the pulling ears are located on the symmetry axis of the first crucible wall 1 and the second crucible wall 2;

[0030] On the outer sides of the first crucible wall 1 and the second crucible wall 2, an upper limit member and a lower limit member for restricting separation are provided. The upper limit member includes a connecting rod 3 that penetrates through the first crucible wall 1 and the second crucible wall 2. At both ends of the connecting rod 3, locking nuts 4 are fixedly connected. The lower limit member is a hoop 5 fixedly connected by bolts.

[0031] The working principle of this application is as follows:

[0032] First, the first crucible wall 1 and the second crucible wall 2 are joined together to form a complete cavity, and the bottom is fixed and limited by the hoop 5. At this time, the first insertion plate 11 is inserted into the spacing between the third insertion plate 12 and the fourth insertion plate 10, and the fourth insertion plate 10 is inserted into the spacing between the first insertion plate 11 and the second insertion plate 9. The carbon product is hoisted and placed into the cavity. Subsequently, the connecting rod 3 is inserted at the top and locked by the locking nut 4, so as to be able to limit the upper and lower parts of the first crucible wall 1 and the second crucible wall 2. Fillers are added, such as one or more mixtures of quartz sand, river sand, or coke particles. Finally, the crucible is hoisted into the roasting furnace for roasting, and then hoisted out after the roasting is completed;

[0033] Hoist the carbon product, loosen the locking nut 4 and pull out the connecting rod 3, remove the hoop 5, and pull the pulling ears to both sides, so that the first crucible wall 1 and the second crucible wall 2 are separated, and the internal filler leaks out. Drive the hoisting equipment to hoist the carbon product out;

[0034] By directly pulling apart the first crucible wall 1 and the second crucible wall 2, the filler can be quickly discharged, and after the crucible is disassembled, hoisting the carbon product again will not cause the carbon product to collide with the crucible wall.

[0035] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model; without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
