Description

Technical Field

[0001] The utility model relates to the technical field of negative electrode material loading kiln cars, in particular to a negative electrode material loading high temperature resistant kiln car. Background Art

[0002] The tunnel kiln car is a special thermal equipment, which not only needs to bear the weight of the product but also needs to withstand high temperature during use. The kiln car is subjected to thermal, mechanical and chemical stress during operation, which can easily cause the kiln car to be damaged and lead to production accidents.

[0003] The existing tunnel kiln car will encounter the following problems during use:

[0004] 1. There are refractory bricks on top of the kiln car. When heated, the refractory bricks have a high heat storage capacity. The stored heat is obtained through external heating. However, this part of the stored heat cannot be directly absorbed by the product, but can only be absorbed by the outside world and wasted. At the same time, refractory bricks are fragile. After high-temperature heating, their brittleness increases, and they will directly lead to rupture under the action of external force, and the maintenance cost after use is high.

[0005] 2. The existing kiln car is insulated only by the refractory bricks on the top. The kiln car's traveling mechanism has no insulation measures. The traveling mechanism is exposed to high temperature for a long time, which will cause it to be damaged. At the same time, when multiple kiln cars are arranged in the tunnel kiln, there will be gaps between the kiln cars, resulting in air leakage and temperature runaway. Utility Model Content

[0006] The utility model aims to provide a high temperature resistant kiln car for loading negative electrode materials, which solves the above problems in the prior art.

[0026] See also Figure 1 , Figure 3 , Figure 4 and Figure 6 A high temperature resistant kiln car for loading negative electrode materials comprises a tunnel kiln 1 and a kiln car 2. The inner wall of the tunnel kiln 1 is symmetrically provided with a thermal insulation flange 101 and a sealing sand groove 102 along its long side. The sealing sand groove 102 is located below the thermal insulation flange 101. Sand and gravel are added to the sealing sand groove 102. The sand and gravel size ratio is 70% of the size of mung bean particles and 30% of small crushed sand. The moisture content is within 6%. It is strictly forbidden to have large debris and bulk items mixed therein. The kiln car 2 comprises a main thermal insulation frame 201 and the thickness of the main thermal insulation frame 201 is consistent with the thickness of the thermal insulation flange 101. When the thickness of the main insulation frame 201 is set to be consistent with the insulation flange 101, the first clamping groove 2012 formed between the main insulation frame 201, the upper insulation frame 202 and the lower insulation frame 203 is clamped together with the main insulation frame 201, so that the temperature inside the tunnel kiln 1 can be isolated above the upper insulation frame 202 to prevent heat loss.

The drill plate 205 is inserted into the sand and gravel of the sand sealing groove 102 to reduce air leakage and temperature escape at the lower part of both sides of the tunnel kiln 1. At the same time, it plays an important role in ensuring the fire speed and the temperature of this part and saving fuel. The lower end of the lower insulation frame 203 is symmetrically fixed with an I-beam 207, and the lower end of the I-beam 207 is rotatably connected with multiple single-sided wheels 208. The kiln car 2 is moved by the single-sided wheel 208 to facilitate the transportation of materials.

[0027] See also Figure 2 Figure 4 and Figure 5The main insulation frame 201, the upper insulation frame 202, the lower insulation frame 203, the first side insulation frame 204 and the second side insulation frame 206 are respectively fixed with high temperature resistant rock wool 3. By setting the main insulation frame 201, the upper insulation frame 202 and the lower insulation frame 203 in a grid shape, and setting the high temperature resistant rock wool 3 in small pieces, when the high temperature resistant rock wool 3 is broken, it is beneficial to quickly replace the high temperature resistant rock wool 3 in the grid, thereby reducing costs. The main insulation frame 201 is staggered with the upper insulation frame 202 and the lower insulation frame 203. The main insulation frame 201, the upper insulation frame 202 and the lower insulation frame 203 have the same width. The length of the main insulation frame 201 is smaller than that of the upper insulation frame 202 and the lower insulation frame 203. The upper insulation frame 202 and the lower insulation frame 203 are consistent in shape and size. The upper insulation frame 202 and the lower insulation frame 203 are placed vertically. The main insulation frame 201 and the upper insulation frame 202 and the lower insulation frame 203 are placed alternately. The portion of the main insulation frame 201 protruding from the upper insulation frame 202 and the lower insulation frame 203 is a clamping portion 2011. A groove is formed between the main insulation frame 201 and the upper insulation frame 202 and the lower insulation frame 203, and the groove on the side opposite to the clamping portion 2011 is a first clamping groove 2012. A groove is formed between the main insulation frame 201 and the upper insulation frame 202 and the lower insulation frame 203, and the grooves on both sides adjacent to the clamping portion 2011 are second clamping grooves 2013.

The main insulation frame 201, the upper insulation frame 202 and the high-temperature resistant rock wool 3 in the lower insulation frame 203 are used for three-time insulation, and most of the heat is in the upper end of the upper insulation frame 202. At the same time, the first side insulation frame 204, the brazing plate 205 and the second side insulation frame 206 are fixed to the lower end of the lower insulation frame 203 to form a square, and the I-beam 207 and the single-sided wheel 208 are surrounded inside, so as to insulate the high temperature in the tunnel kiln 1 again to prevent the single-sided wheel 208 from being damaged due to excessive temperature.

[0028] When the utility model is used:

[0029] First, a support is placed above the kiln car 2, and the container containing the material is placed on the support. When the kiln car 2 is moved into the tunnel kiln 1 for heat treatment, the high temperature resistant rock wool 3 does not absorb heat and has good heat insulation properties, which can greatly reduce energy consumption.

[0030] Then, when the kiln car 2 is pushed into the tunnel kiln 1, the first clamping groove 2012 is clamped with the main insulation frame 201, and the brazing plate 205 is inserted into the sand and gravel in the sand sealing groove 102. When two or more kiln cars 2 enter the tunnel kiln 1, the clamping part 211 is clamped with the first clamping groove 2012 on another kiln car 2 to reduce the gap between the kiln cars 2 and prevent air leakage and temperature runaway.

[0031] Next, the interior of the tunnel kiln 1 is heated and the high temperature resistant rock wool 3 in the main insulation frame 201, the upper insulation frame 202 and the lower insulation frame 203 is insulated three times, and most of the heat is in the upper end of the upper insulation frame 202. At the same time, the first side insulation frame 204, the brazing plate 205 and the second side insulation frame 206 are fixed at the lower end of the lower insulation frame 203 to form a square, and the I-beam 207 and the single-sided wheel 208 are surrounded inside to insulate the high temperature in the tunnel kiln 1 again to prevent the single-sided wheel 208 from being damaged due to excessive temperature. At the same time, the brazing plate 205 is inserted into the sealing sand groove 102 to prevent air from escaping from both sides of the kiln car 2 and reduce air leakage and temperature runaway at the lower parts of both sides of the tunnel kiln 1. At the same time, it plays an important role in ensuring the fire travel speed and the temperature of this part and saving fuel. The clamping part 2011 is clamped with the first clamping groove 2012 on another kiln car 2 to reduce the gap between the kiln cars 2 and prevent air leakage and temperature runaway between the kiln cars 2.

[0032] Finally, after completion, the kiln car 2 can be pulled out of the tunnel kiln 1 by existing equipment.
