Abstract

The invention discloses an oven energy economizer. The oven energy economizer comprises a box body, wherein a heat recovery bin, an energy conservation bin and a waste gas bin are arranged in the box body, two hot air inlets are respectively formed in the bottom and the side wall of the heat recovery bin, a hot air outlet is formed in one side wall of the energy conservation bin, a fresh air inlet is formed in the other side wall of the energy conservation bin, a heat absorbing tube is arranged in the energy conservation bin, a waste gas outlet is formed in the top of the waste gas bin, and the waste gas outlet is connected with an air draft device adjustable in flow. Compared with the prior art, the oven energy economizer collects hot air discharged by an oven, mixes the hot air with fresh air so as to obtain mixing air, and then recycles the mixing air into the oven, and thereby reduces heating electric quantity of a heater, saves energy, protects environment, and is practical, convenient and quick to install, low in cost and simple to operate.

Description

technical field [0001] The invention relates to an oven economizer, which belongs to the technical field of heat recovery. Background technique [0002] At present, the ovens (vertical, tunnel, etc.) used in PCB and FPC processes, or other LED / food baking equipment, all use heater heating to dry board ink at various high temperatures, and the power consumption It is about 560KW per hour, which belongs to high-energy-consuming equipment for industrial processes. The fresh air of the existing oven is the natural supplementary air at the upper end of the equipment, and the temperature is about 35 degrees. In order to meet the characteristics of the ink, a heater is required to heat the temperature inside the oven to the temperature set by the parameters. To ensure that the volatiles do not crystallize in the tank, use The exhaust fan discharges the hot air, causing a large amount of heat loss. Contents of the invention [0003] The present invention provides an oven economi...
