Spraying device for cast iron tube

Abstract

The invention discloses a cast iron pipe spraying device, comprising a conveying track, one end of the conveying track is provided with a group of symmetrically arranged V-shaped grooves, one end of the V-shaped groove is provided with a diagonal brace, the lower end of the V-shaped groove is provided with a push plate, and one end of the push plate is Connected with a jacking cylinder; the outside of the conveying track is provided with a plurality of side-by-side mounting frames, and each mounting frame is equipped with an L-shaped spray pipe, and the spray pipe includes interconnected horizontal pipes and vertical pipes , the bottom of the horizontal tube is evenly distributed with a number of nozzles, one end of the horizontal tube is provided with a sealing plate, the lower end of the vertical tube is connected to the water inlet through the delivery pipe, and the delivery pipe is provided with a booster pump. In the invention, through the structural cooperation of the spray pipe and the conveying track, the cast iron pipe can be rapidly cooled during the conveying process, and the automation degree is high and the cooling effect is good.

Description

technical field [0001] The invention relates to the field of cast iron pipe manufacturing, in particular to a cast iron pipe spraying device. Background technique [0002] Cast iron pipe is a kind of pipe made by pouring cast iron, annealing, zinc spraying, finishing and other processes. It has good mechanical properties, anti-corrosion performance and sealing effect, and is often used in water supply, drainage and gas transmission pipelines. However, since the cast iron pipe is in a high temperature state after annealing, it often occurs that the cast iron pipe burns out the processing equipment in the subsequent manufacturing process, which brings certain obstacles to the production and processing of the cast iron pipe, and the cast iron pipe in the high temperature state will affect the work. Personnel pose a certain safety hazard. Therefore, there is a need for a manufacturing device that can cool down the cast iron pipe during transportation. Contents of the inventio...
