Description

Technical Field

[0001] This utility model relates to the field of sintering furnaces, and in particular to an internal structure of the furnace that can increase the sintering load. Background Technology

[0002] A sintering furnace is a furnace used at high temperatures to bond the solid particles of a ceramic green body together, causing the grains to grow, the voids (pores) and grain boundaries to gradually decrease, and through the transfer of matter, the total volume shrinks and the density increases, eventually becoming a dense polycrystalline sintered body with a certain microstructure.

[0003] Currently, the standard furnace cavity size of traditional batch sintering furnaces on the market is 480*480*2150mm. Due to the fixed size of the furnace cavity, the loading capacity is relatively limited. When products are mass-produced, it is difficult to meet the production capacity requirements. In addition, before sintering, green blanks, ceramic plates and products need to be stacked between two adjacent graphite plates in the graphite box. The space between the two graphite plates is limited. When pushing in multiple layers of materials, if the materials touch each other, it is easy to cause the products to shift. Moreover, the stacking of multiple layers of green blanks, ceramic plates and products results in a large thickness and low heating efficiency. Therefore, this application provides a furnace internal structure that can increase the furnace sintering loading capacity to meet the requirements. Utility Model Content

[0004] The technical problem this utility model aims to solve is to provide an internal furnace structure that can increase the sintering loading capacity of the furnace. This addresses the limitations of existing traditional batch sintering furnaces with a furnace cavity size of 480*480*2150mm. Due to the fixed furnace cavity size, the loading capacity is relatively limited, making it difficult to meet production capacity requirements during mass production. Furthermore, before sintering, green blanks, ceramic plates, and products need to be stacked between two adjacent graphite plates in a graphite box. The limited space between the two graphite plates makes it easy for products to shift if they come into contact when multiple layers of materials are pushed in. Additionally, the stacked layers of green blanks, ceramic plates, and products result in a large thickness and low heating efficiency.

[0005] To solve the problems mentioned above, this utility model is implemented through the following technical solution.

[0006] A furnace internal structure that can increase the sintering loading capacity includes: a first graphite box, wherein 15 sets of first insertion slots are longitudinally formed on both sides of the inner wall of the first graphite box, and the positions of the first insertion slots on both sides of the inner wall of the first graphite box correspond one-to-one; the interior of the first graphite box includes a first graphite plate, a green body, a ceramic plate, and a product; the outer walls on both sides of the green body are wrapped with metal outer sheets, and the bottom of the metal outer sheets is provided with a plurality of directional rollers at intervals; the upper ends of the ceramic plate are provided with sliding grooves on both sides, and the directional rollers are used to slide and push the green body along the sliding grooves to the upper end of the ceramic plate.

[0007] In one embodiment, the first insertion slot is used to insert a first graphite plate. The upper end of the first graphite plate is provided with a green blank, a ceramic plate and a product in sequence. Three sets of green blanks, ceramic plates and products can be placed between every two first graphite plates. The contact surface between the ceramic plate and the product is provided with a reserved groove.

[0008] In one embodiment, three elongated openings are provided between the upper and lower first insertion slots on the inner wall of the first graphite box, and the positions of the elongated openings on both sides of the inner wall of the first graphite box correspond one-to-one, and the thickness of the green embryo is less than the width of the elongated openings.

[0009] In one embodiment, the metal outer sheet wraps around both sides of the green blank, and the contact surface between the green blank and the metal outer sheet is provided with a groove, which is used to limit the position of the metal outer sheet outside the green blank. The upper sides of the first graphite plate are also provided with grooves.

[0010] In one embodiment, the bottom of the metal outer sheath is provided with directional rollers, with no less than 6 rollers in each group, and the height of the directional rollers is greater than the height of the groove.

[0011] In one embodiment, the grooves on both sides of the upper end of the ceramic plate correspond to the positions of the directional rollers at the bottom of the metal outer sheet, and the width of the grooves is 1 mm greater than that of the directional rollers.

[0012] The distance between the green embryo and the adjacent product is 0.15 mm.

[0013] In one embodiment, a second insertion slot is provided on the inner side of the second graphite box.

[0014] In one embodiment, the first graphite box and the second graphite box both have dimensions of 480*480*2150mm.

[0015] In one embodiment, the first graphite box has 15 layers, with two first graphite plates arranged side by side on each layer. The thickness of the first graphite plate is 8mm, and its dimensions are 1070*440*8mm.

[0016] In one embodiment, the second graphite box has 20 layers, with two second graphite plates arranged side by side on each layer. The second graphite plates are 5mm thick and have dimensions of 1070*440*5mm.

[0017] In one embodiment, the width of the first insertion slot is 10mm, and the distance between the upper and lower slots is 18mm.

[0018] In one embodiment, the width of the second insertion slot is 7mm, and the distance between the upper and lower slots is 14mm.

[0019] This invention provides an internal furnace structure that can increase the sintering load. Compared with the prior art, it has the following advantages:

[0020] In the above scheme, by adjusting the specifications inside the furnace cavity, the 7mm insertion slot width in the graphite box was changed to a spacing of 10mm. Before the change, the graphite box loading capacity was 622,080pcs, and after the change, the graphite box loading capacity was 699,840pcs. As can be seen from the above results, the loading capacity increased by 77,760pcs, thus improving the sintering capacity. The directional rollers at the lower end of the green blank are aligned with the sliding grooves opened on the first graphite plate. At this time, the two sides of the green blank are limited to the long strip openings on both sides of the first graphite box. The green blank is pushed into the upper part of the first graphite plate, and the remaining two sets of green blanks, ceramic plates, and products are stacked in sequence. This structure can avoid the situation where the product comes into contact with the newly pushed green blank when the green blanks, ceramic plates, and products are directly pushed in for stacking, causing the product to shift or even fall. In addition, the directional rollers separate the green blanks and ceramic plates by a certain height, creating a distance of 1.5mm between them. When sintering in the first graphite box, the air circulation is better, the heating efficiency is higher, and the sintering efficiency is improved. Attached Figure Description

[0031] The first insertion slot 2 is used to insert the first graphite plate 3. The upper end of the first graphite plate 3 is provided with a green blank 4, a ceramic plate 9 and a product 10 in sequence. Three sets of green blanks 4, ceramic plates 9 and products 10 can be placed between every two first graphite plates 3. A reserved groove 11 is opened on the contact surface between the ceramic plate 9 and the product 10.

[0032] Three long openings 5 ​​are provided between the two first insertion slots 2 on the inner wall of the first graphite box 1, and the positions of the long openings 5 ​​on both sides of the inner wall of the first graphite box 1 correspond one-to-one. The thickness of the green blank 4 is less than the width of the long openings 5.

[0033] The metal outer sheet 6 is wrapped around the outside of the blank 4 on both sides, and the contact surface between the blank 4 and the metal outer sheet 6 is provided with a groove 12. The groove 12 is used to limit the position of the metal outer sheet 6 outside the blank 4. The upper end of the first graphite plate 3 is also provided with grooves 12 on both sides.

[0034] The bottom of the metal outer sheet 6 is provided with directional rollers 7, with no less than 6 rollers in each group, and the height of the directional rollers 7 is greater than the height of the slide groove 8.

[0035] The grooves 8 on both sides of the upper end of the ceramic plate 9 correspond to the positions of the directional rollers 7 at the bottom of the metal outer sheet 6, and the width of the grooves 8 is 1 mm greater than that of the directional rollers 7.

[0036] The distance between the green embryo 4 and the adjacent product 10 is 0.15 mm.

[0037] The second graphite box 13 has a second insertion slot 14 on its inner side.

[0038] The first graphite box 1 and the second graphite box 13 both have dimensions of 480*480*2150mm.

[0039] The first graphite box 1 has 15 layers in total. Each layer has two first graphite plates 3 placed side by side. The thickness of the first graphite plate 3 is 8mm, and its size is 1070*440*8mm.

[0040] The second graphite box 13 has 20 layers in total. Each layer has two second graphite plates 15 placed side by side. The second graphite plates 15 are 5mm thick and have dimensions of 1070*440*5mm.

The distance between the upper and lower slots of the first insertion slot 2 is 18mm. The second insertion slot 14 is 7mm wide and has a distance of 14mm between its upper and lower slots. Before the change, the loading capacity of the second graphite box 13 was 622080pcs, calculated as follows: 960*324=311040pcs (a full furnace can hold 960 ceramic plates per layer). The distance between the upper and lower second graphite plates 15 is... The thickness is 16mm, and the number of stackable layers is: 16 / 2+3+1.5=2.46, which can be stacked into 2 layers. The total loading capacity is: 311040*2=622080pcs. The loading capacity of the first graphite box 1 after the change is: 699840pcs, calculated as follows: 720*324=233280pcs (the number of ceramic plates that can be placed in a single layer of the furnace is 720).
