Description

Technical Field

[0001] The utility model relates to the technical field of ceramic firing equipment, and particularly relates to an electric kiln for ceramic firing. Background Art

[0002] Ceramic firing is a process of heating ceramic raw materials under high-temperature conditions to cause chemical and physical changes, and finally obtaining hard and dense ceramic products. Firing equipment is required during the ceramic firing process. Among them, an electric kiln is a device that uses electric energy to generate high temperature for operations such as melting, sintering, and heat treatment, and is widely used in the field of ceramic firing.

[0003] Electric kilns are usually divided into large electric kilns and small electric kilns. Large electric kilns are suitable for large-scale industrial firing of ceramics, and small electric kilns are suitable for firing small batches or single products. During the use of a small electric kiln, if small batches of ceramics need to be fired, the ceramics need to be stacked in layers. In the layered stacking, multiple partitions are usually separated vertically by pad bricks to stack ceramics on multiple partitions.

[0004] However, the heights of different types of ceramics are different. At this time, if the height of the pad brick is fixed, it is easy to cause the problem that the height difference between two adjacent partitions is too large or too small. At this time, different pad bricks need to be replaced for use, which is inconvenient during the use process. Content of the Utility Model

[0005] The purpose of the utility model is to provide an electric kiln for ceramic firing, which has the function of conveniently adjusting the height difference between two upper and lower partitions according to the height of the ceramics.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: An electric kiln for ceramic firing includes an electric kiln body with a firing cavity and a shelving rack arranged in the firing cavity for ceramic layered shelving. The shelving rack includes a plurality of heightening mechanisms and a plurality of partitions. Each partition is shelved on at least two heightening mechanisms, and the heightening mechanism for shelving the upper partition is placed on the lower partition. The heightening mechanism includes a lower wedge block, an upper wedge block slidably connected to the upper surface of the lower wedge block, two adjusting blocks with arc-shaped surfaces, an adjusting screw passing through the two adjusting blocks, and an adjusting nut threadedly connected to the adjusting screw. The upper surface of the lower wedge block extends obliquely downward towards the rear side close to the electric kiln body. A lower movable groove is arranged in the middle of the upper surface of the lower wedge block, and a lower arc-shaped groove communicated with the lower movable groove is arranged at the front side of the lower wedge block. An upper movable groove corresponding to the lower movable groove is arranged in the middle of the lower surface of the upper wedge block, and upper arc-shaped grooves communicated with the upper movable groove are arranged at the front and rear of the upper wedge block. The arc-shaped surfaces of the two adjusting blocks are respectively embedded at the lower arc-shaped groove and the upper arc-shaped groove, and the adjusting screw moves in the lower movable groove and the upper movable groove.

[0007] By adopting the above technical solution, by changing the position of the adjusting nut on the adjusting screw, the distance between the two adjusting blocks can be changed. At this time, since the arc surfaces of the two adjusting blocks are respectively placed at the lower arc groove and the upper arc groove, the upper wedge block can be driven to slide relative to the lower wedge block, so as to adjust the height difference between the upper surface of the upper wedge block and the lower surface of the lower wedge block, so as to adjust the height of the height-adjusting mechanism. When the partition is placed on the two adjusting mechanisms, it has the function of conveniently adjusting the height difference between the upper and lower partitions according to the height of the ceramic.

[0008] The further setting of the present utility model is: each side of the partition is placed on a height-adjusting mechanism, a magnet is embedded on the upper surface of the upper wedge block, and a strip iron sheet that can be adsorbed by the magnet during the adjustment of the upper wedge block is embedded on the lower surface of the partition.

[0009] By adopting the above technical solution, by embedding a magnet on the upper surface of the upper wedge block and embedding a strip iron sheet on the lower surface of the partition, the partition and the height-adjusting mechanism are adsorbed when connected, improving the connection stability.

[0010] The further setting of the present utility model is: open grooves with a "convex" cross-section are provided on the front and rear sides of the upper wedge block. Each partition is placed on two stacked height-adjusting mechanisms. After the upper height-adjusting mechanism is inverted, the upper wedge blocks of the two height-adjusting mechanisms are attached to each other, and a connecting piece is inserted between the corresponding open grooves of the upper wedge blocks of the two height-adjusting mechanisms. A connecting groove is provided on the lower surface of the lower wedge block, and a connecting block is provided on the lower surface of the partition and is embedded in the connecting groove of the lower wedge block of the upper height-adjusting mechanism.

[0011] By adopting the above technical solution, when a single height-adjusting mechanism is used, the position of the upper surface of the upper wedge block relative to the partition is variable. If the upper wedge block is too close to the front or rear side of the partition, the stability during connection is relatively poor. At this time, by setting the two height-adjusting mechanisms in a stacked form, after the upper height-adjusting mechanism is inverted, the lower wedge block of the upper height-adjusting mechanism is connected to the partition, which can fix the connection position with the partition, and the stacking of the two height-adjusting mechanisms can increase the height adjustment range.

[0012] The further setting of the present utility model is: a connecting bolt is provided between the end of the connecting piece and the open groove.

[0013] By adopting the above technical solution, the stability of the two stacked height-adjusting mechanisms can be increased by setting the connecting bolt.

[0014] The further setting of the present utility model is: a plurality of downwardly protruding arc-shaped reinforcing ribs are provided on the lower surface of the partition.

[0015] By adopting the above technical solution, by providing a plurality of downwardly protruding arc-shaped reinforcing ribs, the structural strength of the partition can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Embodiment 1: An electric kiln for ceramic firing, comprising an electric kiln body 1 having a firing cavity 11, and a shelving rack 2 disposed in the firing cavity 11 for layering and shelving ceramics. The shelving rack 2 includes a plurality of heightening mechanisms 21 and a plurality of partitions 22. Each partition 22 is placed on at least two heightening mechanisms 21, and the heightening mechanism 21 for placing the upper partition 22 is placed on the lower partition 22.

[0024] Such as Figures 2 to 4As shown in the figure, the heightening mechanism 21 includes a lower wedge block 211, an upper wedge block 212 slidably connected to the upper surface of the lower wedge block 211, two adjusting blocks 213 with arc-shaped surfaces, an adjusting screw 214 passing through the two adjusting blocks 213, and an adjusting nut 215 threadedly connected to the adjusting screw 214. The upper surface of the lower wedge block 211 extends obliquely downward towards the rear side close to the electric kiln body 1. A lower movable groove 2111 is provided in the middle of the upper surface of the lower wedge block 211, and a lower arc-shaped groove 2112 communicating with the lower movable groove 2111 is provided at the front side of the lower wedge block 211. A corresponding upper movable groove 2121 is provided in the middle of the lower surface of the upper wedge block 212, and upper arc-shaped grooves 2122 communicating with the upper movable groove 2121 are provided at the front and rear of the upper wedge block 212. The arc-shaped surfaces of the two adjusting blocks 213 are respectively embedded at the lower arc-shaped groove 2112 and the upper arc-shaped groove 2122, and the adjusting screw 214 moves within the lower movable groove 2111 and the upper movable groove 2121.

[0025] As Figure 3 and Figure 4 shown in the figure, each side of the partition plate 22 is placed on a heightening mechanism 21. A magnet 216 is embedded in the upper surface of the upper wedge block 212, and a strip-shaped iron sheet 221 that can be adsorbed to the magnet 216 during the adjustment of the upper wedge block 212 is embedded in the lower surface of the partition plate 22. A plurality of downwardly protruding arc-shaped reinforcing ribs 222 are provided on the lower surface of the partition plate 22.

[0026] Implementation effect: By changing the position of the adjusting nut 215 on the adjusting screw 214, the distance between the two adjusting blocks 213 can be changed. At this time, because the arc-shaped surfaces of the two adjusting blocks 213 are respectively placed at the lower arc-shaped groove 2112 and the upper arc-shaped groove 2122, the upper wedge block 212 can be driven to slide relative to the lower wedge block 211, so as to adjust the height difference between the upper surface of the upper wedge block 212 and the lower surface of the lower wedge block 211, so as to adjust the height of the heightening mechanism 21. When the partition plate 22 is placed on the two adjusting mechanisms, it has the function of conveniently adjusting the height difference between the upper and lower partition plates 22 according to the height of the ceramics.

[0027] By embedding a magnet 216 on the upper surface of the upper wedge block 212 and a strip-shaped iron sheet 221 on the lower surface of the partition plate 22, the partition plate 22 and the heightening mechanism 21 are adsorbed to each other during connection, improving the connection stability. By providing a plurality of downwardly protruding arc-shaped reinforcing ribs 222, the structural strength of the partition plate 22 can be improved.

[0028] Embodiment 2: An electric kiln for firing ceramics, as Figure 5As shown in the figure, the difference from Embodiment 1 is that: opening grooves 2123 with a "convex" cross-section are provided on both the front and rear sides of the upper wedge block 212. Each partition of the partition plate 22 is placed on two stacked heightening mechanisms 21. After the upper heightening mechanism 21 is inverted, the upper wedge blocks 212 of the two heightening mechanisms 21 are attached to each other. A connecting piece 217 is inserted between the corresponding opening grooves 2123 of the upper wedge blocks 212 of the two heightening mechanisms 21. A connecting groove 2113 is provided on the lower surface of the lower wedge block 211, and a connecting block 223 embedded in the connecting groove 2113 of the lower wedge block 211 of the upper heightening mechanism 21 is provided on the lower surface of the partition plate 22. A connecting bolt 218 is provided between the end of the connecting piece 217 and the opening groove 2123.

[0029] Implementation effect: When a single heightening mechanism 21 is used, the position of the upper surface of the upper wedge block 212 relative to the partition plate 22 is variable. If the upper wedge block 212 is too close to the front or rear side of the partition plate 22, the stability during connection is relatively poor. At this time, by setting the form of two stacked heightening mechanisms 21, after the upper heightening mechanism 21 is inverted, the lower wedge block 211 of the upper heightening mechanism 21 is connected to the partition plate 22, so that the connection position with the partition plate 22 can be fixed. And at this time, the stacking of the two heightening mechanisms 21 can increase the height adjustment range. By setting the connecting bolt 218, the stability of the two stacked heightening mechanisms 21 can be increased.
