Problems solved by technology

[0008] 1. The push plate kiln and tunnel kiln use coal gas or natural gas to burn, resulting in higher production costs, greater waste of resources, serious pollution, and not environmentally friendly
[0009] 2. Existing push plate kilns and tunnel kilns use coal gas or natural gas for combustion. The disadvantages are that the temperature difference is large, it is easy to arch the kiln, resulting in poor product consistency (some raw and some cooked), and the worker's operation intensity is high (continuous operation).
[0010] 3. The manufacturing cost of push plate kiln and tunnel kiln is also high

Abstract

The invention discloses an electric kiln, which comprises a kiln body, a kiln hearth and a kiln hearth port, wherein a kiln door is arranged on the kiln body positioned on one side of the kiln hearth port; the kiln wall of each side of the kiln body has a structure consisting of outer, middle and inner layers; each outer layer is a metal shell; each middle layer is a heat-insulating layer; each inner layer is a heating layer. The electric kiln has the characteristics of convenience, high flexibility, high mobility, easiness and convenience in operation, low pollution and low cost, and is suitable for the field of firing of corundum aeration heads.

Description

[0001] technical field [0002] The invention relates to the technical field of aeration head firing processing, in particular to an electric kiln. Background technique [0003] Push plate kiln, also known as push plate furnace or push plate tunnel kiln, is a continuous heating and sintering equipment. According to the process requirements of sintered products, the required temperature zone and power are arranged to form the thermal part of the equipment to meet the requirements of the product. Caloric needs. The sintered products are directly or indirectly placed on the high-temperature-resistant and abrasion-resistant push plate, and the product placed on the push plate is moved by the propulsion system according to the technological requirements of the product, and the sintering process of the product is completed in the furnace. [0004] The pusher kiln belongs to the category of small tunnel kiln. The combustion chamber designed on both sides of the pusher kiln is cal...
