Description
Technical Field
[0001] The utility model belongs to the field of silicon nitride silicon carbide product infiltration silica sol process, and specifically relates to an auxiliary frame for silicon nitride combined silicon carbide brick infiltration silica sol. Background Art
[0002] After silicon nitride combined with silicon carbide bricks and recrystallized silicon nitride bricks are fired and taken out of the kiln, it is necessary to penetrate the silica sol material as deeply as possible into the surface of the product under vacuum to fill the pores and improve its density. The traditional method requires manual transportation of each block into the vacuum pit and transfer of each block to the designated location after penetration, which is inefficient and there is also the problem of bumps and damage to the products during transportation. Summary of the invention
[0003] In order to solve the above technical problems, the purpose of the utility model is to provide an auxiliary frame for silicon nitride bonded silicon carbide bricks infiltrated with silica sol.
[0004] The utility model adopts the following technical solutions to achieve the above purpose:
[0005] An auxiliary frame for infiltrating silicon sol with silicon nitride bonded silicon carbide bricks, the auxiliary frame comprising an upper cover plate and a lower cover plate; the upper cover plate and the lower cover plate are connected via balance columns at four corners; the upper and lower ends of each balance column respectively pass through the upper cover plate and the lower cover plate; a space for placing brick products is formed between the upper cover plate and the lower cover plate; the lower cover plate is provided with multiple rows of infiltration slots; the brick products placed on the lower cover plate are cross-arranged with the infiltration slots; the upper cover plate is provided with lifting holes for conveniently transporting the auxiliary frame to vacuum pit foundation equipment; the bottom surface of the lower cover plate is provided with multiple support ribs for supporting the auxiliary frame; the height of the support ribs is greater than the length of the balance column passing through the lower cover plate.
[0006] The upper and lower ends of each balancing column respectively pass through the upper cover plate and the lower cover plate and are fastened by a positioning safety pin and an anti-dropping safety pin.
[0007] The upper end of the balance column is provided with a stepped shaft for matching with the upper cover plate.
[0008] The utility model proposes an auxiliary frame for silica sol infiltration of silicon nitride bonded silicon carbide bricks. The above technical scheme is adopted to solve the problem of low efficiency in the process of silica sol infiltration of silicon nitride bonded silicon carbide products and recrystallized silicon carbide products, which requires manual single-piece transportation to the vacuum pit foundation and single-piece transportation to the designated location after infiltration. The use of the device effectively improves the efficiency of silica sol infiltration, reduces the problem of bumps and damages caused by products during transportation, is convenient and quick to assemble and maintain, and has significant economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 It indicates that the auxiliary frame has been assembled;
[0010] Figure 2 This is a partial enlarged view of a balance column of the auxiliary frame.
[0011] In the figure: 1-anti-drop safety pin; 2-upper cover plate; 3-lifting hole; 4-step shaft; 5-balance column; 6-infiltration slot hole; 7-lower cover plate; 8-positioning safety pin; 9-support rib. DETAILED DESCRIPTION
[0012] The utility model is described in detail with reference to the accompanying drawings and specific embodiments:
[0013] like Figure 1 As shown, an auxiliary frame for silicon nitride bonded silicon carbide bricks infiltrated with silica sol, the auxiliary frame having an upper cover plate 2 and a lower cover plate 7; the upper cover plate 2 and the lower cover plate 7 are connected by balance columns 5 at four corners; the upper and lower ends of each balance column 5 pass through the upper cover plate 2 and the lower cover plate 7 respectively; a space for placing brick products is formed between the upper cover plate 2 and the lower cover plate 7; the lower cover plate 7 has multiple rows of infiltration slots 6; the brick products placed on the lower cover plate and the infiltration slots 6 are arranged crosswise; the upper cover plate has a hoisting hole 3 for conveniently transporting the auxiliary frame to the vacuum pit foundation equipment; the bottom surface of the lower cover plate has multiple support ribs 9 for supporting the auxiliary frame; the height of the support ribs is greater than the length of the balance column passing through the lower cover plate. When the auxiliary frame of the product is placed on the ground, the balance column 5 is suspended to facilitate the loading and unloading of silicon nitride bonded silicon carbide products.
[0014] When in use, place the lower cover plate 7 on the ground and make it contact with the ground through the support ribs 9, then pass the four balance columns 5 through the matching holes at the four corners of the lower cover plate 7. When the reserved holes for the positioning safety pins 8 on the lower end surface of the balance column 5 are no longer blocked by the lower cover plate 7, the positioning safety pins 8 can be assembled. After the positioning safety pins 8 are assembled, tightening nuts are installed on both sides of the positioning safety pins 8 to prevent them from falling off. The upper cover plate 2 is further installed on the upper ends of the four balance columns 5. When the lower end surface of the upper cover plate 2 is supported by the stepped shaft 4 on the balance column 5, it can be considered that the upper cover plate 2 is installed in the correct position. Then assemble the four upper anti-dropping safety pins 1 with it, tighten the tightening nuts on both sides, and place the brick products on the upper end surface of the lower cover plate 7 in a staggered arrangement to expose the infiltration slots 6. Then use a lifting device to transport it to the vacuum pit foundation equipment through the lifting holes 3 on the upper cover plate 2.
[0015] In order to prevent the silica sol from being incompletely infiltrated, more through slots with higher density can be provided on the lower cover plate 7 while ensuring the stability of the structure, so as to enhance the penetration effect of the silica sol.
[0016] The utility model is not only used in the field of silicon nitride and silicon carbide products infiltrating silica sol technology, but is also suitable for various cage structures for transportation and lifting, all of which belong to the protection scope of the present invention.
