Description

Technical Field

[0001] The utility model belongs to the technical field of graphite processing and production, and specifically relates to a high-temperature cooling silo. Background Art

[0002] Graphitization refers to the process of heating non-graphite carbon to above 2000°C in a protective medium in a high-temperature electric furnace or in an airtight state. Due to physical changes, the hexagonal carbon atom plane mesh layer stacking structure is improved and developed, and the product is transformed into graphite carbon with a three-dimensional regular and orderly structure of graphite. Graphitization improves the product's volume density, electrical conductivity, thermal conductivity, corrosion resistance and mechanical processing performance. Graphitization is a key process in the production of artificial graphite negative electrodes.

[0003] The temperature of the material produced from the graphitization furnace is very high and carries a large amount of heat energy. If the heat of the material is dissipated by natural heat dissipation, it will be slow, and the dissipated heat will cause the working environment temperature to rise. In addition, so much heat dissipation will also cause waste. Therefore, it is necessary to design a device that can quickly cool the high-temperature material produced by the graphitization furnace and recover heat. Utility Model Content

[0004] The utility model aims to provide a high-temperature cooling silo, which can be used to quickly cool high-temperature materials in a graphitization furnace and recover heat.

DETAILED DESCRIPTION

[0020] 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.

[0021] In one embodiment, a high temperature cooling silo is provided, such as Figure 1 As shown, the high temperature cooling silo includes a support frame 1, on which a cooling water jacket silo body 2 is arranged. The side wall of the cooling water jacket silo body 2 can be cooled by circulating cooling water. Figure 3 As shown, a grate 3 for screening bulk materials is provided on the top of the cooling water jacket bin body 2. The materials output from the outlet at the bottom of the cooling water jacket bin body 2 will reach the slag cooler in the next step. The grate 3 is a screen set according to the particle size of the material to prevent bulk materials from entering the cooling water jacket bin body 2 and being transported to the slag cooler of the next process flow, causing blockage.

[0022] The high-temperature cooling silo is a device that can cool high-temperature materials and has two functions. On the one hand, it cools the high-temperature materials through circulating cooling water, and on the other hand, it screens the materials through the grate 3 on the top of the cooling water jacket silo 2 to prevent large pieces of material from clogging the slag cooler below.

[0023] The high-temperature cooling silo is specifically cooled by passing cooling circulating water into the cooling water jacket silo body 2. After the high-temperature material enters the cooling water jacket silo body 2, the heat of the high-temperature material is transferred to the circulating cooling water through the side wall of the cooling water jacket silo body 2. In this way, the passed cooling circulating water can absorb the heat of the high-temperature material to cool it down.

[0024] The working process of the high-temperature cooling silo is as follows: after the high-temperature material produced by the graphitization furnace is initially cooled, it is sucked into the cooling water jacket silo 2 by the suction crane, and circulating cooling water is introduced into the cooling water jacket silo 2 to cool the high-temperature material again. The circulating water used for cooling can recycle the heat of the material; after the high-temperature material is cooled in the cooling water jacket silo 2, it directly enters the slag cooler through the discharge port at the bottom or enters the slag cooler through a vibrating conveyor for the next step of cooling.

[0025] Further, in one embodiment, if Figure 2 As shown, the side wall 21 of the cooling water jacket silo 2 of the high-temperature cooling silo is a sandwich structure, that is, the side wall 21 has two layers, so that a sandwich cavity 211 is formed in the side wall 21 of the cooling water jacket silo 2, and the sandwich cavity 211 is connected with a water inlet 212 and a water outlet 213, and the water inlet 212 and the water outlet 213 are arranged at intervals on both sides, so that the low-temperature water flowing into the sandwich cavity 211 from the water inlet 212 fully absorbs heat and then flows out from the water outlet 213. In other embodiments, a surrounding pipe can also be set outside or inside the side wall of the cooling water jacket silo to pass circulating cooling water to cool the high-temperature material.

[0026] Further, in one embodiment, if Figure 1-2 As shown, the high-temperature cooling silo is provided with a stacking hopper 4 surrounded by side plates on the support frame 1, and the stacking hopper 4 is located on the upper side of the grate 3. When the high-temperature material produced by the graphitization furnace is sucked by the suction crane and placed on the grate 3, accumulation may occur, and the stacking hopper 4 can prevent the high-temperature material from falling from the side.

[0027] Further, in one embodiment, if Figure 1-2 As shown, the cooling water jacket silo body 2 of the high-temperature cooling silo includes a conical cooling hopper 22 consisting of four side surfaces, a load-bearing frame 23 is provided on the top of the cooling hopper 22, and the support frame 1 of the high-temperature cooling silo includes a front row of supporting legs 5 and a rear row of supporting legs 6 respectively arranged on the front and rear sides of the load-bearing frame 23, wherein the bottoms of the front row of supporting legs 5 and the rear row of supporting legs 6 are respectively provided with connecting cross beams 7, and the front row of supporting legs 5 and the rear row of supporting legs 6 each have three legs, which are connected by the connecting cross beams 7.

[0028] A first connecting block 51 is provided between the front supporting leg 5 and the load-bearing frame 23, a second connecting block 52 is provided between the front supporting leg 5 and the corresponding connecting cross beam 7, and a first diagonal brace 53 is provided between the first connecting block 51 and the second connecting block 52. Correspondingly, a first connecting block is also provided between the rear supporting leg and the load-bearing frame, a second connecting block is provided between the rear supporting leg and the corresponding connecting cross beam, and a first diagonal brace is also provided between the first connecting block and the second connecting block corresponding to the rear supporting leg.

[0029] A third connecting block 54 is provided in the middle of the front supporting leg 5, a fourth connecting block 55 is provided in the middle of the corresponding side of the load-bearing frame 23, and a second diagonal brace 56 is provided between the third connecting block 54 and the fourth connecting block 55. Correspondingly, a third connecting block is also provided in the middle of the rear supporting leg, a fourth connecting block is also provided in the middle of the corresponding side of the load-bearing frame, and a second diagonal brace is also provided between the third connecting block and the fourth connecting block corresponding to the rear supporting leg. The first diagonal brace 53 and the second diagonal brace 56 are segmented connecting rods, which are convenient for changing the length to meet the needs.

[0030] The cooling water jacket silo body 2 of the high-temperature cooling silo includes a cooling hopper 22 and a load-bearing frame 23 on its top. The cooling water jacket silo body 2 of this structure can be manufactured separately first and then installed on the support frame 1. It is more convenient to install on the support frame 1, and the cooling water jacket silo body 2 has a relatively firm structure. The support frame 1 is designed to include a front support leg 5 and a rear support leg 6 on the front and rear sides, which can also be manufactured separately, and the front support leg 5 and the rear support leg 6 can replace each other. The front support leg 5 and the rear support leg 6 can be used interchangeably after being manufactured according to standards; by setting a first connecting block 51 between the front support leg 5 and the load-bearing frame 23, setting a second connecting block 52 between the front support leg 5 and the connecting crossbeam 7, setting a first diagonal rod 53 between the first connecting block 51 and the second connecting block 52, and by setting a third connecting block 54 on the front support leg 5, setting a fourth connecting block 55 on the load-bearing frame 23, and setting a second diagonal rod 56 between the third connecting block 54 and the fourth connecting block 55, the support frame 1 is firmly connected to the cooling water jacket compartment body 2 as a whole, and the overall structure is stable and more durable.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated 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 that the scope of the present invention is defined by the appended claims and their equivalents.
