Energy-saving and environment-friendly thermal circulation tunnel kiln

Abstract

The invention discloses an energy-saving and environment-friendly thermal circulation tunnel kiln. The energy-saving and environment-friendly thermal circulation tunnel kiln comprises a kiln frame, abrick wall is fixedly connected to the inner part of the kiln frame, a mounting plate is arranged on the lower part of the kiln frame, the mounting plate is fixedly connected with the kiln frame through a plurality of supporting plates which are symmetrically arranged, heating boxes are correspondingly and fixedly connected to the two sides of the kiln frame, heating plates are fixedly connected to the inner walls of the heating boxes, gas transmission pipes are inserted into the tops of the heating boxes, the ends, away from the heating boxes, penetrate through the brick wall and extend inward, a motor is fixedly connected to the top of the mounting plate, and a first gear is fixedly connected to the output end of the motor. According to the energy-saving and environment-friendly thermalcirculation tunnel kiln, through the driving of the motor, the heating circulation speed is increased, and the operation efficiency of the tunnel kiln is improved.

Description

technical field [0001] The invention relates to the technical field of tunnel kiln equipment, in particular to an energy-saving and environment-friendly thermal cycle tunnel kiln. Background technique [0002] Tunnel kiln is made of refractory materials, thermal insulation materials and building materials. It is a kiln similar to a tunnel with kiln cars and other vehicles inside. It is a modern thermal equipment for continuous firing. The existing tunnel kiln When heating the inside, the used hot gas cannot be recycled, and the circulation speed is slow, which makes the thermal insulation performance of the hot gas poor, which has certain defects. Contents of the invention [0003] 1. Technical problems to be solved [0004] The purpose of the present invention is to solve the problem that the used hot gas cannot be recycled when the tunnel kiln is heating the interior in the prior art, and the circulation speed is relatively slow, which makes the thermal insulation perfo...
