Description

Technical Field

[0001] The utility model relates to a sintering material rack for graphite hard felt, belonging to the technical field of graphite hard felt sintering. Background Art

[0002] Graphite felt is obtained by high-temperature treatment of carbon felt in vacuum or inert atmosphere. Its carbon content is higher than that of carbon felt, reaching more than 99%. It has good thermal insulation, heat insulation and electrical conductivity, and is widely used in the industrial field. Graphite hard felt is a graphite product formed by adding colloid and then sintering and curing. It has good shape retention, self-support, small specific gravity, low thermal conductivity, high temperature resistance, good thermal vibration resistance (no cracking or deformation after long-term use), long service life, easy installation and replacement, etc., and is widely used in the industrial field.

[0003] When existing graphite hard felt is sintered, it is generally placed on a sintering rack first, and then the sintering rack is placed in a sintering furnace for sintering. Since the graphite hard felt itself is a thermal insulation material with low thermal conductivity, and since the heater is on the outside, it takes a relatively long time for the heat to be transferred to the center of the hard felt. The temperature difference between the periphery and the middle of the hard felt is large, which can easily cause the product quality to fail to meet the standards.

[0004] In response to the above situation, corresponding patents have also appeared in the industry to solve the problem, such as the application number: 202320152194.1, the patent name is: A Chinese authorized utility model patent for a hard felt sintering rack. In the above patent, graphite paper is laid on the upper and lower surfaces of the graphite hard felt respectively, and heat is transferred to the center of the graphite hard felt through the graphite paper to accelerate the heat transfer.

[0005] However, in the above-mentioned patent, graphite paper is laid on the upper and lower surfaces of each graphite felt, and the graphite paper in the above-mentioned patent is directly laid on the upper and lower surfaces of the graphite felt without any fixation. Since the graphite paper is relatively soft and light, when the graphite felt is moved, the graphite paper will float with the graphite felt, resulting in the graphite paper not being in the set position, affecting the subsequent use of the graphite paper. At the same time, the thickness of the graphite felt varies, while the distance between each layer in the above-mentioned patent is fixed and cannot be adjusted according to the thickness of the graphite felt to be sintered, which affects the ventilation effect between the graphite felts, and further affects the sintering effect of the graphite felt. Summary of the invention

[0006] The technical problem to be solved by the utility model is to provide a sintering material rack for graphite hard felt to solve the problems faced in the industry.

[0031] In order to support the graphite paper fixing structure 5, the support plate 420 is further in a rectangular structure, a plurality of support bosses 421 are arranged on the side of the support plate 420, and connecting through holes 422 are arranged at both ends of the length direction of the support plate 420, and the connecting screws 412 are inserted into the connecting through holes 422.

[0032] like Figures 10 to 12 As shown, further, the graphite paper fixing structure 5 includes a fixed base 6 with a rectangular structure, an intermediate boss 601 is arranged in the middle of the upper surface of the fixed base 6, and a pressure plate groove 602 with a rectangular structure is arranged around the intermediate boss 601. A fixed pressure plate 7 is arranged in the pressure plate groove 602, and a plurality of intermediate through grooves 603 are arranged on the intermediate boss 601. A plurality of fixed connecting holes 604 are respectively arranged on the front and rear sides of the fixed base 6, and the fixed connecting holes 604 pass through from the outer side of the fixed base 6 to the pressure plate groove 602, and graphite paper 8 is arranged between the fixed pressure plate 7 and the fixed base 6.

[0034] In order to prevent the graphite hard felt 2 from being misplaced when being placed, a rear baffle 304 is further provided on the back of the connecting frame 3 .

[0035] When in use, first place the connecting seat plate 411 of the T-shaped connecting seat 410 into the T-shaped groove 303. When placing, first place the connecting seat plate 411 vertically into the T-shaped groove 303, and then rotate the connecting seat plate 411 90 degrees so that the connecting seat plate 411 on the T-shaped connecting seat 410 can hook the T-shaped groove 303, and then put the connecting through hole 422 on the support plate 420 on the connecting screw 412 of the T-shaped connecting seat 410, and engage the nut 413 with the connecting screw 412, so that the support plate 420 and the T-shaped connecting seat 410 are locked on the connecting column 302 through the nut 413, and a plurality of support structures 4 are arranged on the connecting column 302.
