Embodiment Construction

[0026] refer to figure 1 , figure 2 and image 3 The present invention will be further described.

[0027] like figure 1 As shown, this embodiment includes an outer casing 1, an inner casing 2, an air channel 3, a conveyor belt 4, a heat exchanger 5, an air intake channel, 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 .

[0028] The outer casing 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 casing 1. The outer casing 1 is the outermost layer of the oven. The outer casing 1 is a carrier for the oven to work, and the cavity of the outer casing 1 is also a space for heat energy circulation.

[0029] The left side plate, the right side plate, the upper side plate and the lower side plate of the inner casing 2 enclose the struc...

Abstract

The invention relates to an energy-saving tunnel drying oven. The energy-saving tunnel drying oven comprises an outer shell, an inner shell, an air channel, a conveyor belt, a heat exchanger, an air inlet, a heat pump system, fans, heating devices, an air flow distributor, an air exhaust pipe and the like. Outside air enters the air channel through the air inlet, the air is preheated by the heat exchanger, heated by the heat pump system and subjected to auxiliary constant temperature keeping by the heating devices, and the air heats and dries heated objects on the conveyor belt; and through distributing of the air flow distributor, the part of hot air is subjected to heat exchanging by the heat exchanger and then exhausted through the air exhaust pipe, and the other part of hot air is mixed with new air preheated by the heat exchanger, heated by the heat pump system and heated by the heating devices, then heats and dries the heated objects, and is distributed by the air flow distributor, in this way, heat energy in the air is circularly utilized, the energy is saved, and the heating efficiency is improved. When the working environment temperature is high, the heat pump system can further be used for cooling the working environment while being used for 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 the effect of rapid drying, 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 used for drying and drying needs with high output and high efficiency requirements. It can be widely used in assembly lines for drying various items. [0003] At present, tunnel ovens only use heating wires and / or infrared lamps for heating. The air is heated by the heating wires and / or infrared lamps and flows to the conveyor belt to heat the items on the conveyor belt, and then part of the air with residual heat i...
