Direct-fired intelligent fuel gas tunnel furnace

Abstract

The invention provides a direct-fired intelligent fuel gas tunnel furnace. The direct-fired intelligent fuel gas tunnel furnace comprises a rack, driving mechanisms which are mounted at the front and rear ends of the rack, a furnace body assembly which is mounted in the middle of the rack, and end edge sealing heads which are installed at the front end and the rear end of the furnace body assembly, and a reversing pushing and blocking mechanism is installed in one end edge sealing head; the direct-fired intelligent fuel gas tunnel furnace further comprises a control system which comprises a PLC control center, and the PLC control center is electrically connected with a driving mechanism, a moisture removal fan, humidity sensors and temperature sensors installed in air uniformizing assemblies, air inlet adjusting valves of combustion pipe bodies, ignition needles and pushing air cylinders. According to the direct-fired intelligent fuel gas tunnel furnace, through the structural design of the driving mechanisms and the furnace body, automatic steering transmission of a product in the furnace body can be achieved, the requirement of the baking tunnel furnace for the longitudinal length of an installation site is greatly lowered, accurate control over the temperature and humidity in the baking tunnel furnace can be achieved, and the intelligent degree is high.

Description

technical field [0001] The invention relates to a tunnel furnace, in particular to a direct-fired intelligent gas tunnel furnace. Background technique [0002] The food gas baking tunnel furnace (referred to as the tunnel furnace) consists of a roughly rectangular parallelepiped furnace body, which is divided into sections every 2-3 meters, and the sections are connected together with a conveyor belt for transporting the products to be baked, an electric control system, The heating system forms a continuous baking tunnel. The furnace body is provided with a plurality of flame injection tubes for heating, and each flame injection tube is perpendicular to the length direction of the tunnel furnace, and the plurality of flame injection tubes are distributed at intervals in the length direction of the tunnel furnace. For example, the Chinese patent application whose publication number is CN103875746A discloses a tunnel type hot air circulation tunnel furnace, including a furnac...

AI Technical Summary

Problems solved by technology

[0003] But existing baking tunnel furnace mainly exists following several defects: (1) existing baking tunnel furnace is rectangular parallelepiped horizontal setting, and length is longer, usually needs to be set to more than 20 meters, and floor area is big, and the installation of site ( Especially the longitudinal length) has high requirements; (2) The control of the temperature and humidity inside the existing baking tunnel furnace is inaccurate, which leads to uneven heating of baked products and reduces the quality of baked products

(3) Low degree of intelligence
