Abstract

A paint spraying device for a round block hole type graphite heat exchanger, disclosed by the present invention, specifically comprises a fixing support, wherein sliding ways are formed in the two sides of the fixing support, positioning devices are slidably connected to the inner walls of the sliding ways, and one ends of the positioning devices extend to the outer side of the fixing support; a fixed top plate of which the bottoms at the two ends are fixedly connected with the top of the fixing support, wherein the parts, located on the inner side of the fixing support, of the two ends of the fixed top plate are fixedly connected with hydraulic lifting rods and fixed sliding ways, and the fixed sliding ways are arranged on the fixed top plate and fixedly connected with the fixed top plate. The present invention relates to the graphite heat exchanger paint spraying technical field, and according to the paint spraying device for the round block hole type graphite heat exchanger, positioning can be completed only by moving a positioning disc during positioning, the use and operation are easy, the clamping force can be freely and slowly increased or decreased, the situation that a workpiece is damaged due to the fact that the clamping force borne by the heat exchanger is too large is avoided, the workpiece does not need to be lifted to a clamping station for positioning and clamping, and the manpower and material resources are conveniently saved.

Description

technical field [0001] The invention relates to the technical field of painting for graphite heat exchangers, in particular to a painting device for round hole graphite heat exchangers. Background technique [0002] In the application of petroleum and chemical production, the heat exchanger is one of the most extensive unit equipment. It accounts for about 20% of the total investment in petroleum and chemical plant construction, and accounts for more than 40% of the chemical equipment in the whole plant. It is processed with graphite. There are many kinds of heat exchangers, such as round block hole type, tube and tube type, rectangular block hole type, plate type, squirrel cage type and so on. Considering the heat transfer efficiency, fluid flow resistance, structural strength, manufacturing cost, installation and maintenance of the heat exchanger, among them, the round hole graphite heat exchanger is the most widely used, and the round hole graphite heat exchanger, It is ...
