Surface refinement treatment process of boiler coal-fired sieve plate after casting

Abstract

The invention relates to a fine surface treatment process of a boiler coal-fired sieve plate after casting, including a transmission mechanism, a polishing mechanism and a turning mechanism. The number of the transmission mechanism and the polishing mechanism is two, and the transmission mechanism is placed on the working ground Above, the polishing mechanism is installed on the top center of the transmission mechanism through bolts, the turning mechanism is located in the middle of the two transmission mechanisms, that is, the two transmission mechanisms are connected through the turning mechanism, and the worktable is placed on the ground. A rectangular through hole is opened at the inner center of the table top, and the first driving shaft and the driven shaft are respectively installed at both ends of the rectangular through hole, the transmission belt is installed on the outer wall of the first driving shaft and the driven shaft, and the first driving shaft The first driven wheel is installed at one end, and the first motor is installed under the side of the working surface close to the first driven wheel. The present invention can realize the rapid flipping of the sieve plate, more energy-saving operation, and partial replacement of the polished steel wire.

Description

technical field [0001] The invention relates to the technical field of boiler sieve plate manufacturing technology, in particular to a fine surface treatment process of a boiler coal-fired sieve plate after casting. Background technique [0002] The original meaning of the pot refers to the water container heated on the fire, and the furnace refers to the place where fuel is burned. The boiler includes two parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or converted into electrical energy through a generator. Boilers that provide hot water are called hot water boilers, which are mainly used in daily life, and also have a small amount of application in industrial production. The sieve plate is an indispensable component of the boiler. It is often formed by casting during produc...

Problems solved by technology

[0003] However, the surface refinement treatment process of the boiler coal-fired sieve plate in the current market has the following problems in the operation process: a. Due to the surface refinement treatment process of the boiler coal-fired sieve plate after casting and molding , it is necessary to manually turn over the sieve plate, and the size and weight of the sieve plate are large, which greatly consumes manpower, and the turning efficiency is low and the safety is low; b. Due to the traditional boiler coal-fired sieve plate casting The position of the polished steel wire in the surface refinement treatment process after forming is located in the same plane, so that the contact time between the polished steel wire and the sieve plate is not sufficient, thus prolonging the polishing time and causing a large energy loss. At the same time, when the polished steel wire is partially damaged When the maintenance personnel need to replace the polished steel wire as a whole, the operation is cumbersome, and the polished steel wire is not fully utilized
