Technical Field

The invention relates to a portable submerged arc welding flux heating warmer.

Background

Submerged arc welding is efficient welding, has the advantages of stable welding quality, high efficiency, no arc light and smoke and the like, and is widely applied to plate seam welding. According to the requirements of submerged arc welding technology, the welding flux can be applied to welding operation only by heating to a certain temperature, the submerged arc welding flux heating equipment is large in size and inconvenient to move, and is generally fixed in an operation area, but the welding flux is required to be transferred to an operation position under the conditions that an operation place is far away from the heating equipment or the operation place environment is complex and large heating equipment is inconvenient to place, and the temperature loss is more in the process, so that the welding quality is influenced. The auxiliary working time is longer.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provide a portable submerged arc welding flux heating warmer which is small in size, light in weight, convenient to move, capable of being arranged in an operation area and used along with a heating welding flux. The temperature loss in the flux transfer process is avoided, and the welding quality is not influenced. The heating is convenient and fast, a large amount of auxiliary work is reduced, and the operation efficiency is improved.

In order to achieve the purpose, the technical scheme of the invention is to design a portable submerged arc welding flux heating warmer which comprises a warmer body, wherein the warmer body is in a circular groove shape, the middle space of the warmer body is used as a heating and heat preservation cavity of the submerged arc welding flux, and a heating element is arranged in the side wall of the warmer body.

A further technical scheme is that the heating member is the heater strip, the heat retainer body includes the heat-preserving container, and the heat-preserving container includes the rock wool pipe and the cladding is at the iron protective layer on rock wool pipe surface, and the heater strip setting is intraductal at the rock wool.

The further technical proposal is that the inner diameter of the rock wool pipe is 200mm, and the height is 1000 mm; and a baffle cover arranged at the upper end of the heat retainer body is also matched with the heat retainer body. The heater capacity is 25KG of flux, i.e. a bag of flux. The powder is quickly heated by a 220V power supply and then is insulated by a multi-head welding machine, the heating speed is about 15 minutes, the highest temperature can reach about 300 ℃, and the requirement of heating and insulating the powder is met. The portable submerged arc welding agent heating heat retainer is small in size, light in weight and convenient to move, can be arranged in an operation area, and can be used along with a heating agent. The temperature loss in the flux transfer process is avoided, and the welding quality is not influenced. The heating is convenient and fast, a large amount of auxiliary work is reduced, and the operation efficiency is improved.

The further technical scheme is that the heat retainer body comprises a circular groove-shaped base, a heating wire is arranged in the side wall of the base, a flexible heat-preserving barrel is fixedly arranged on the base, a cavity is arranged on the side wall of the flexible heat-preserving barrel, and the lower end of the cavity is opposite to the heating wire. The flexible heat-preserving container is made of thin aluminum alloy, and can be bent to better place the submerged arc welding flux heating heat retainer when the environment of an operation place is complex.

The outer wall of the flexible heat-insulating barrel is coated with a heat-insulating layer, the side wall of the base is internally provided with an annular cavity, and the annular cavity is internally provided with the heating wire; the cavity of the side wall of the flexible heat-insulating barrel is communicated with the annular cavity of the side wall of the base. The heat insulation layer is made of flexible rubber materials or heat insulation cotton. Therefore, heat generated by the heating wire is firstly transferred to the cavity, then the heated air in the cavity transfers the heat to the inner wall of the aluminum alloy, and the outer wall of the aluminum alloy rarely emits the heat outwards due to the arrangement of the heat insulation layer. The other scheme is that the cavity is removed on the basis, and the thin aluminum alloy is directly used as the flexible heat-insulating barrel, but the outer wall of the thin aluminum alloy still needs to be provided with a heat-insulating layer.

The invention has the advantages and beneficial effects that: the volume is small, the weight is light, the movement is convenient, and the heating flux can be arranged in an operation area and used along with the heating flux. The temperature loss in the flux transfer process is avoided, and the welding quality is not influenced. The heating is convenient and fast, a large amount of auxiliary work is reduced, and the operation efficiency is improved. The flexible heat-preserving container is made of thin aluminum alloy, and can be bent to better place the submerged arc welding flux heating heat retainer when the environment of an operation place is complex.
