Description

Kiln structure improvement

This creation is about a kind of kiln's internal structure design, especially a kind of kiln structure improvement that is not easy to be damaged, can be overlapped and connected in series, and further extends the service life.

In a common kiln, after placing various types of fired products on the carrier, the carrier and the fired products are sintered in the kiln in a stacked type. Regarding the structure of the kiln, it basically includes a closed furnace body made of stacked heat-breaking bricks, with a continuous passage in the center, and combined furnace core bricks in the passage to provide burned products to be placed inside. In order to facilitate the firing, heating elements are arranged at the upper and lower or left and right ends of the channel to provide the required sintering temperature of the product. A connected exhaust hole is arranged above the channel to remove exhaust gas.

Although this type of kiln structure can meet the general needs and is widely used, after long-term observation by the applicant, it is found that the structure of the furnace core brick is not perfect, which affects the quality of the fired product. In other words, the density of the furnace core bricks is insufficient in assembly, and the gas is easy to leak, which causes the furnace wall to be affected by atmospheric erosion and relatively increases the damage rate of the equipment. Furthermore, when firing electronic ceramic sintered products, toxic gases or impurities will be generated during the firing process, and large amounts of emissions will form pollution on the inner wall of the channel and erode and destroy the thermal insulation bricks over a long period of time, ultimately resulting in shortened use life.

In view of this, the creator has made long-term research and continuous experimentation to address the deficiencies and imperfections of the existing industrial furnace structure, and is dedicated to improving the furnace body. In order to improve its work efficiency and expect to be more economical, it finally developed a brand new original creation.

The first purpose of this creation is to provide an improved kiln structure, through the combination of different types of furnace core bricks and overlapping combinations, to achieve the required rapid firing effect and improve the quality of the fired products.

To achieve the above-mentioned purpose, a set of upper and lower core bricks with overlapping functions are mainly arranged in the furnace body. The upper furnace core brick is arched and is an arc-shaped surface combined with extending and opposite vertical surfaces at both ends. , The free edges of the two vertical surfaces respectively form corresponding concave-convex or convex-concave engaging parts. The lower furnace core brick is in the shape of a rectangle, and the opposite sides of the two vertical surfaces are formed with vertical surfaces. The free edges of the two vertical surfaces are respectively formed with convex-concave or concave-convex clamping parts, which can be connected to the upper furnace core brick on the two vertical surfaces. The engaging parts of the two are matched; thereby, the height difference between the engaging part and the engaging part is superimposed to achieve a better air tightness effect.

The above-mentioned other set of opposite sides of the upper and lower core bricks can be respectively formed with a convex lap joint and a concave joint groove, so that each group of upper and lower core bricks can be connected to the previous or rear A set of upper and lower furnace core bricks can be connected in series.

The above-mentioned curved surface of the upper furnace core brick can be respectively formed with protruding laps and recessed joint grooves on the opposite long sides of the arc surface, and the rectangular surface of the lower furnace brick can be respectively formed with protruding laps on the opposite long sides. The joint part and the recessed joint groove make all the upper and lower furnace core bricks use the position difference between the front and back of the overlapping part and the joint groove to achieve mutual series connection and connection with the front or rear upper and lower furnace core bricks. Dense effect.

A hole can be timely opened on the curved surface of the upper furnace core brick.

The above-mentioned upper and lower furnace core bricks can be made of any one of alumina, graphite, quartz, and silicon carbide.

The furnace wall (12) is also provided with an opening (not shown in the figure) that can be controlled to open and close, which is connected to the channel (11), so that the fired material can be fed into the channel (11) of the furnace (1) through this opening Fired inside. On the top of the kiln (1), an exhaust hole (13) is connected with the passage (11).

Please continue to refer to the second figure, which is an exploded view of the core brick structure of a preferred embodiment; wherein the core brick (2) includes an upper core brick (21) and a lower core brick (22) , The upper furnace core brick (21) is arched, and is an arc-shaped surface (211) with short sides combined with extending and opposite vertical surfaces (212). The free sides of the two vertical surfaces (212) respectively form corresponding Concave-convex or convex-concave engagement portion (213). The lower furnace core brick (22) is U-shaped, and is a rectangular surface (221) forming vertical surfaces (222) on opposite sides. The free edges of the two vertical surfaces are respectively formed with convex-concave or concave-convex clamping portions (223) , Which can be matched with the engaging parts (213) of the free edges of the two vertical surfaces (212) of the upper core brick (21), thereby forming the required complete core brick (2) structure, as shown in the third figure .

The upper and lower furnace core bricks (21, 22) can be made of any one of alumina, graphite, quartz, and silicon carbide.

Refer again to the front view of the core brick structure of a preferred embodiment shown in Figure 4; according to the above-mentioned upper and lower core bricks (21, 22) in implementation, the upper core brick (21) is directly covered The lower furnace core brick (22) can be assembled by using the height difference between the clamping portion (213) and the clamping portion (223) to complete the combination, so as to achieve a better air tightness effect.
