Spraying device and spraying method applied to energy-saving paint on furnace inner wall

Abstract

The invention relates to a device and method for spraying energy-saving paint on inner walls of furnaces. The spraying device is characterized by comprising a material tank body, a feeding hopper, a support and a pipeline which is connected with the material tank body, wherein the material tank body is arranged on the support; the feeding hopper is arranged at one side above the material tank body; an Y-shaped connector is arranged below the material tank body; one end of the Y-shaped connector is connected below the material tank body; the other end of the Y-shaped connector is connected witha compressed air pipeline; and a pressure gauge and a material tank exhaust ball valve are also arranged above the material tank body. The spraying device provided by the device has the advantages that the device is simple in structure and convenient to operate; the spraying device and the spraying method directly adopt compressed air pressure as power; the use stability, the use safety and the use reliability of the spraying device are truly realized; the maintenance time is saved; the construction efficiency is improved; and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to a spraying device, in particular to a spraying device and a spraying method applied to an energy-saving paint on the inner wall of a furnace, and belongs to the technical field of industrial furnace construction equipment. Background technique [0002] In order to protect the refractory material on the inner wall of the steel rolling heating furnace, prevent the cracking, peeling off of the refractory material, and sinking of the furnace body caused by the long-term erosion of the refractory material by the furnace gas, and increase the radiation rate of the heating furnace furnace to reduce fuel consumption. , it is necessary to regularly spray and construct energy-saving coatings on the inner wall of the furnace. At present, the energy-saving coatings sprayed on the inner wall of the steel rolling heating furnace in the industry are all anti-corrosion and wear-resistant far-infrared energy-saving coatings, and its volume dens...
