Spiral plate heat exchanger welding machine

Abstract

The invention discloses a spiral-plate heat exchanger welding machine is a very suitable machine for machining spiral-plate heat exchangers. According to the adopted technical measures, the spiral-plate heat exchanger welding machine comprises a rack, a rotary disk is arranged on the rack, and a welding gun is arranged on the outer side of the rotary disk. The spiral-plate heat exchanger welding machine is characterized in that a transverse beam is connected to a stand column in the horizontal direction, the welding gun is connected to a clamping mechanism, the clamping mechanism is connected with a pushing mechanism arranged on the transverse beam, a probe used for detecting the position of a spiral plate is arranged in the position of the welding gun, the probe is connected with the pushing mechanism through a controller and used for controlling work of the pushing mechanism, and the welding gun moves in the length direction of the transverse beam under the action of the pushing mechanism; the controller is further used for controlling the rotation speed of the rotary disk after receiving signals of the probe; an automatic wire feeder is used for automatically delivering welding wires to the welding gun. The welding machine is high in operation speed and very suitable for welding integral heat exchange plates.

Description

technical field [0001] The invention relates to a welding machine, in particular to a welding machine used for welding a spiral plate heat exchanger. Background technique [0002] In the fields of medicine and chemical industry, it is usually necessary to apply heat exchangers to use heat exchange between fluid media and materials to achieve the purpose of heating or cooling materials. As a kind of heat exchanger, the spiral plate heat exchanger is relatively widely used. The main heat exchange function is the heat exchange plate arranged on the substrate. The heat exchange plate is arranged in a spiral, and the spirally arranged heat exchange plate separates the substrate It forms two independent curved cavities, and the two cavities respectively flow into the material and the heat exchange medium. When the material and the heat exchange medium flow through the two cavities, the material and the heat exchange medium receive continuous heat. exchange. Since the material an...

Problems solved by technology

[0004] The heat exchange steel plate in this spiral plate heat exchanger is formed by welding multiple pieces stacked together. Due to the relatively complex chemical properties of the material, too many welds on the heat exchange plate will be caused by the material. Penetration occurs due to corrosion, and this kind of multi-piece heat exchange steel plate is stacked and welded together, which is relatively troublesome when processing, and the processing efficiency is relatively low
