Embodiment Construction

[0025] refer to figure 1 , figure 2 and image 3 The present invention will be further described.

[0026] Such as figure 1 As shown, this embodiment includes an outer casing 1, an inner casing 2, an air passage 3, a conveyor belt 4, a heat exchanger 5, an air intake passage, a heat pump system 7, a fan bracket 8, a fan 9, a baffle 10, and a heating device 11 , air flow distributor 12, connecting pipe 13 and exhaust pipe 14.

[0027] The outer shell 1 is a hollow square box, which is composed of the front side plate, the rear side plate, the left side plate, the right side plate, the upper side plate and the lower side plate of the outer shell 1. The outer shell 1 is the outermost layer of the oven. The outer casing 1 is the carrier for the oven to work, and the cavity of the outer casing 1 is also a space for heat energy to circulate.

[0028] The left side plate, the right side plate, the upper side plate and the lower side plate of the inner shell 2 enclose the struct...

Abstract

Disclosed is a tunnel oven, comprising an outer housing (1), an inner housing (2), an air channel (3), a conveyor belt (4), a heat exchanger (5), an air inlet (6), a heat pump system (7), fans (9), a heating device (11), an air flow distributor (12), and an exhaust pipe (14), wherein outside air enters the air channel (3) through the air inlet (6), and the air is pre-heated by the heat exchanger (5) and heated by the heat pump system (7), and the temperature of which is kept constant with the aid of the heating device (11) to heat and dry an object, which is to be heated, on the conveyor belt (4); and hot air is distributed by the air flow distributor (12), some of the hot air being exhausted through the exhaust pipe (14) after heat exchange by the heat exchanger (5), and some of the hot air being mixed with new air which is pre-heated by the heat exchanger (5) and then being heated by the heat pump system (7), then being heated by the heating device (11), heating and drying the object to be heated, and then being distributed by the air flow distributor (12). Recycling heat energy in the air in such a way saves energy and improves heating efficiency. If the temperature in an operation environment is relatively high, the heat pump system (7) can be used to cool the operation environment while heating the air.

Description

technical field [0001] The invention relates to a tunnel oven, in particular to an energy-saving tunnel oven. Background technique [0002] The oven heats the electric heating tube through the power supply to generate a heat source. When it is absorbed by the heated object, it can be directly converted into heat energy, thereby obtaining a fast drying effect, shortening the production cycle, saving energy, and improving product quality. Tunnel oven is a kind of oven that adopts long box hot air circulation and infrared drying method for drying. It is mainly for the drying and drying needs of high output and high efficiency. It can be widely used on the assembly line to dry various items. [0003] At present, the tunnel oven only uses heating wires and (or) infrared lamps for heating. After being heated by the heating wires and (or) infrared lamps, the air flows to the conveyor belt to heat the items on the conveyor belt, and then part of the air with residual heat is directl...
