Adjustable ceramic roller kiln nozzle layout structure

Abstract

The embodiment of the invention discloses an adjustable ceramic roller kiln nozzle layout structure. The adjustable ceramic roller kiln nozzle layout structure comprises a kiln body, a roller way arranged in the kiln body, upper nozzles and lower nozzles, wherein the upper nozzles and the lower nozzles are arranged in the kiln body and symmetrically arranged on the left side and the right side ofa kiln body burning zone; the upper nozzles are positioned above the roller way; the lower nozzles are positioned below the roller way; and the upper nozzles and the lower nozzles are in one-to-one correspondence and are arranged symmetrically up and down. According to the adjustable ceramic roller kiln nozzle layout structure, the layout mode of original nozzles is changed, so that gas turbulenceinside a kiln is enhanced, gas flowing is accelerated, the temperature difference is reduced, and therefore the uniformity of a temperature field is improved, the heat transfer rate is increased, andthe quality of a ceramic product is improved.

Description

technical field [0001] The present application relates to the technical field of roller hearth kiln, in particular to an adjustable burner layout structure of ceramic roller hearth kiln. Background technique [0002] With the rapid development of my country's economy, people's demand for ceramics is increasing rapidly, and at the same time, the requirements for product types and quality are getting higher and higher. Roller kiln is one of the main firing equipment for ceramic production, and it is also the core of the production of ceramic enterprises. The quality of products is affected by the distribution of the temperature field in the furnace. Therefore, the optimization of the temperature field is particularly important. . In order to meet the production requirements of high-quality products, customization, and fast replacement speed, ceramic enterprises urgently need to comprehensively realize the optimization of the temperature field of the roller kiln from two aspec...

Problems solved by technology

[0003] At present, most of the optimization research on roller kiln only focuses on the change of the process parameters of the firing zone or the change of the furnace structure, which is weakly targeted and the optimization effect is not obvious. The research on the burner of the key part of the kiln It also only stays in the design of the combustion device, the change of the inclination angle, etc., and does not analyze it from a systematic and holistic perspective, and cannot solve the problems of low heat transfer rate and poor uniformity inside the kiln. For this reason, the present invention proposes An adjustable burner layout structure of ceramic roller kiln
