Description

[Detailed Description of the Invention] The present invention relates to an improvement of a cart for smoking ceramic products used when smoking ceramic products such as smoked roof tiles.

Conventional trolleys for smoking ceramic products include:
Generally, a capsule receiving gutter installed around the periphery of the cart is filled with sand or ceramic fibers, but because sand and ceramic fibers are breathable, they are When the smoking capsule is set, even if its leg ends are embedded in sand or ceramic fibers, the bottom opening of the smoking capsule cannot be completely sealed, and outside air is allowed to escape during the cooling process after smoking. It has the disadvantage that it can enter the smoking capsule and change the color tone of the smoked ceramic product or cause poor smoking.

This invention was completed with the aim of creating a trolley for smoking ceramic products that does not have the above-mentioned drawbacks.
A capsule receiving gutter 2 is provided around the periphery of the main body 1 of the cart, and a lower layer 3 made of heat-resistant rubber is disposed within the capsule receiving gutter 2.
It is characterized by being filled with a sealing material 5 made of a surface layer 4 made of a heat-resistant fibrous heat insulating material and a sealing material 5 made of a heat-resistant fibrous heat insulating material.

With this structure, the ceramic product to be smoked is placed on the main body 1 of the cart, and the capsule for smoking is placed in a capsule receiving gutter whose leg frame is wrapped around the periphery of the main body 1 of the cart. The ceramic product is set in a state where it is supported by the sealing material 5 in 2, and the ceramic product is smoked in the kiln by supplying the smoking gas into the smoking capsule from the smoking gas supply pipe C. This is similar to the conventional trolley for smoking ceramic products of this type, but according to the present invention, the sealing material 5 filled in the capsule receiving gutter 2 is composed of a lower layer 3 made of heat-resistant rubber such as silicone rubber and ceramic fibers. Since it is a laminated packing consisting of a surface layer 4 made of a heat-resistant fibrous insulating material such as glass fiber or asbestos, the leg frame will be shaped as shown in the figure when the smoking capsule is set. The bottom layer 3 made of heat-resistant rubber is cut into the bottom layer 3 made of heat-resistant rubber together with a part of the surface layer 4 made of heat-resistant fibrous heat insulating material, and the lower end of the smoking capsule is sealed by the heat-resistant rubber, which has no air permeability and has excellent elasticity. The opening can be completely sealed, and it is possible to eliminate color changes in smoked ceramic products and product defects due to infiltration of outside air. In addition, the surface of the lower layer 3 made of heat-resistant rubber is covered with the surface layer 4 made of a heat-resistant fibrous heat insulating material that has far superior heat resistance than the lower layer 3, so it is less susceptible to heat effects and has a lower weight. The lower layer 3 made of heat-resistant rubber cushions the impact that the surface layer 4 made of heat-resistant fibrous heat insulating material that directly supports the leg frame of the large smoking capsule receives when setting the smoker capsule due to its elasticity. Therefore, there is no fear of cutting the surface layer 4, and it can be used for a long time.
Since it is not necessary to frequently replace the sealing material 5, the number of maintenance, inspections, repairs, etc. can be reduced.
As mentioned above, the main purpose of the surface layer 4 made of heat-resistant fibrous heat insulating material is to thermally protect the lower layer 3 made of heat-resistant rubber, so the surface layer 4 can be made thin within the scope of its purpose. Generally, the wall thickness ratio of the lower layer 3 and the surface layer 4 is set to about 1:1 to 4:1 in consideration of sealing performance, but the thinner the surface layer 4 is, the better the sealing performance is. Of course, the surface layer 4 may be further thinned by taking measures to continuously supply cooling water to the capsule receiving trough 2 during work.

Therefore, the present invention eliminates the drawbacks of the conventional smoking cart made of ceramic products of this type, and also eliminates the need to supply inert gas into the smoking capsule during the cooling process after smoking to prevent outside air from entering. This has the advantage of reducing running costs since there is no heat exchanger, and together with the advantages of simple structure and low cost, the practical value is extremely great.
