Problems solved by technology

[0003] At present, the propellers of the equipment are assembled and welded with the propeller shaft for pressure test. There are a large number of propellers welded on the propeller shaft, with hundreds of weld beads. During the pressing process, there are often leaks in many welds. (or air leakage), which brings disorder and safety hazards to on-site production, high rework rate, poor appearance quality of weld bead, large welding deformation, which seriously affects manufacturing quality and work efficiency

Abstract

The invention discloses a hollow blade pressing device and method, and belongs to the technical field of machinery and environmental protection. A sealing gasket is connected with an eyelet bolt through a nut, the eyelet bolt is connected with a paddle through a clamp, the sealing gasket and the paddle form a sector, an arc supporting plate is connected with the paddle, the arc supporting plate and an exhaust pipe are fixed to a support, one end of a water injection pipe is connected with a pressurizing pump, the other end of the water injection pipe is connected with a water inlet in the arc supporting plate, one end of the valve is connected to the exhaust pipe, and a pressure gauge pipeline interface is connected with a pressure gauge. The device has the advantages that: the disordered state caused by simultaneous pressure test of multiple groups of paddle and shaft welding seams is eliminated, the manufacturing quality of equipment is enhanced, the working efficiency of equipment manufacturing is improved, and the potential safety hazard of a pressure test is greatly reduced.

Description

technical field [0001] The invention relates to a hollow paddle pressing device and method, and belongs to the technical fields of machinery and environmental protection. Background technique [0002] The paddle dryer is a horizontal stirring dryer mainly based on conduction. Its notable advantages include: compact structure, high heat transfer efficiency, self-cleaning function, simple control, less dust and odor generated, auxiliary Facilities and so on. Therefore, it is not only used for drying treatment of municipal sludge, but also widely used in chemical industry, smelting, food and other fields. [0003] At present, the propellers of the equipment are assembled and welded with the propeller shaft for pressure test. There are a large number of propellers welded on the propeller shaft, with hundreds of weld beads. During the pressing process, there are often leaks in many welds. (or air leakage), which brings disorder and safety hazards to on-site production, high rew...
