Compact type drying oven for two household appliances (condenser and evaporator)

Abstract

The invention discloses a compact type drying oven for two household appliances (a condenser and an evaporator). The compact type drying oven for the two household appliances (the condenser and the evaporator) comprises a two-appliance conveying line, a drying oven body, a hot air circulating system, a sweeping system and an exhaust gas purifying system, wherein the drying oven body is mounted at the upper part of the two-appliance conveying line, and two ends of the drying oven body are provided with openings; preheating pipelines of the hot air circulating system and the sweeping system are arranged in a hearth of the drying oven; the hot air circulating system and the exhaust gas purifying system are arranged at the upper part of the drying oven; the sweeping system is arranged at the lower part of the two-appliance conveying line; the two household appliances move from the inlet end of the drying oven body to the outlet end of the drying oven body through the two-appliance conveying line so as to finish the drying process. The compact type drying oven for the two household appliances (the condenser and the evaporator) has the advantages of efficiently recovering the exhaust waste heat, reducing the energy consumption and improving the hot air efficiency; the portability that volatile oil instantaneously explodes can be greatly reduced, so that the running safety of equipment can be ensured; the content of volatile oil in exhaust gas can be greatly reduced, and thus the exhaust gas can realize environmentally-friendly emission; a drying workshop with a limited site, low processing capacity of the drying oven and high-calorific-value fuel particularly applies; the equipment are compact, so that he investment can be saved.

Description

technical field [0001] The invention belongs to the field of home appliance production, in particular to a compact two-device drying oven for home appliances. Background technique [0002] The two appliances of household appliances refer to the condenser and the evaporator, which are punched by a high-speed punch. In order to ensure the product shape and processing quality, lubricating oil is used in the stamping process, and the lubricating oil needs to be removed in subsequent production to ensure the final quality and performance of the product. In large home appliance manufacturing enterprises, two-drying furnaces are commonly used to dry the two devices with high-temperature and high-speed hot air, so that the lubricating oil attached to the surface of the two devices can quickly volatilize to meet the processing needs of subsequent processes. The existing two-device drying furnace mostly adopts an automatic transmission system, which is suitable for mass and continuou...

AI Technical Summary

Problems solved by technology

Most of the exhaust gas after drying the workpiece is discharged without utilization, and the exhaust gas temperature is high and easy to flash

Due to the above characteristics, the drying energy consumption is large, the hot air drying efficiency is low, the tail gas utilization is weak, and the production safety is poor, which not only causes a great waste of energy but also brings great hidden dangers to production safety.
