Description

Technical Field

[0001] The utility model relates to the technical field of ceramic firing, in particular to a feeding rack and a firing kiln for ceramic production. Background Technique

[0002] Ceramics are handicrafts made by using clay to form blanks and then firing them at high temperature. In the prior art, for industrial production, a large number of blanks are usually placed on a feeding rack and then fired uniformly.

[0003] Existing feeding racks are all made of high-temperature resistant materials. During the firing process, the entire feeding rack is pushed into the kiln. However, there are dimensional deviations between the kiln and the feeding rack. During the high-temperature firing process, strong temperature stresses will be generated, resulting in the need for additional positioning and fixing of the feeding rack in the kiln to prevent adjacent feeding racks from colliding with each other.

[0004] However, in the actual production and processing process, the existing feeding racks lack equipment for fixing with the kiln, and existing rigid fixing parts cannot be applied to the temperature during the kiln firing, resulting in difficulty in stably fixing the feeding rack in the kiln. Content of the Utility Model

[0005] The purpose of the utility model is to provide a feeding rack and a firing kiln for ceramic production to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A feeding rack is provided with three layers of laminates. A material plate is inserted on one side of the laminate. A sleeve ring is arranged on the side wall of the material plate. An inverted U-shaped positioning column is inserted and fixed on the upper laminate. The positioning column is inserted through the sleeve ring. A screw rod is rotationally installed on the side wall of the positioning column through threads. Positioning sleeves and positioning rods are respectively arranged on the front and back sides of the feeding rack in corresponding distributions.

[0008] Preferably, adjacent pairs of the feeding racks are fixed by inserting the positioning rods and positioning sleeves. A handle is arranged on one side of the feeding rack close to the positioning sleeve.

[0009] Preferably, rollers are arranged at the lower end of the feeding rack, and multiple groups of grooves for supporting the blanks are linearly distributed on the material plate.

[0010] A firing kiln for ceramic production includes a kiln. A pair of side frames are symmetrically arranged on the outer side of the kiln. Multiple groups of the above feeding racks are arranged in the inner cavity of the kiln. The port of the kiln is fixedly sealed by a sealing door. The screw rods on both sides of the feeding rack abut against the inner wall of the kiln. A lifting drive device for driving the sealing door to lift is arranged on the side frame.
