An electric heating type air energy heat circulation heating furnace

Abstract

The invention discloses an electric heating type air energy thermal circulation heating furnace, which relates to the technical field of heating furnaces. The top of the inner piston plate is fixedly installed with a contraction spring, and the top of the contraction spring is fixedly connected to the top of the inner wall of the air circulation groove. One side of the air circulation groove and above the inner piston plate is provided with a hot air exhaust hole. When the blade rotates to input cold air, the cold air enters the air circulation tank through the first filter screen and the second filter screen, and the impurities carried by the cold air are accumulated on the second filter screen during the flow of the cold air. The rotation of the cam, through the combined action of the rotation of the cam and the guide spring on the guide rod, can drive the first scraper and the second scraper to reciprocate along the guide rod along the partition plate, so as to remove the impurities accumulated at the bottom of the second filter screen. to clean up.

Description

technical field [0001] The invention relates to the technical field of heating furnaces, in particular to an electric heating type air energy heat circulation heating furnace. Background technique [0002] In the metallurgical industry, heating furnaces are equipment (industrial furnaces) that heat materials or workpieces (usually metals) to rolling forging temperatures. Heating furnaces are widely used in petroleum, chemical, metallurgy, machinery, heat treatment, surface treatment, building materials, In many industries such as electronics, materials, light industry, daily chemicals, pharmaceuticals, etc., heating furnaces can be divided into many types according to the heating methods and media used. Among them, the use of air to heat them is called air energy. Heating furnace, and because the air energy heating furnace generally heats the air and discharges it into the heating furnace, heats the space in the furnace, and then discharges the air, but at this time there is...

[0002] In the metallurgical industry, heating furnaces are equipment (industrial furnaces) that heat materials or workpieces (usually metals) to rolling forging temperatures. Heating furnaces are widely used in petroleum, chemical, metallurgy, machinery, heat treatment, surface treatment, building materials, In many industries such as electronics, materials, light industry, daily chemicals, pharmaceuticals, etc., heating furnaces can be divided into many types according to the heating methods and media used. Among them, the use of air to heat them is called air energy. Heating furnace, and because the air energy heating furnace generally heats the air and discharges it into the heating furnace, heats the space in the furnace, and then discharges the air, but at this time there is still a lot of heat in the air, directly Emission to the outside world is easy to cause waste of resources

[0003] In addition, since some impurities in the heating furnace will enter the air circulation tank along with the air during the hot air circulation process, a filter is installed at the input end of the cold air exhaust hole, but with the continuous use of the equipment, the impurities will disappear Accumulated on the filter screen, and then block the filter screen, so that the cold air cannot enter the air circulation tank, affecting the operation of the device
