Pipe surface spraying equipment for waterworks construction

Abstract

The invention discloses a pipe surface spraying equipment for water plant construction, which comprises a fixed base, a treatment box is fixed on the top of the fixed base, a screw installation box is fixed on the top of the treatment box, and a two-way screw rod is horizontally arranged inside the screw installation box, and the spraying The motor mounting plate is fixed on the top side wall on the right side of the box, the servo motor is installed on the top of the motor mounting plate, the synchronous driving wheel is sleeved on the output end on the right side of the servo motor, the rotating rod is fixed on the right side of the two-way screw rod, and the right side of the rotating rod runs through the wire. The side wall of the right end of the rod installation box is sleeved with a synchronous driven wheel. The outer wall of the two-way screw rod is located on two sets of opposite thread directions. Clamp and fix the side walls at the left and right ends of the bottom of the pipe, and fix the pipe to facilitate grinding. The inner wall and outer wall of the pipe can be polished at the same time, and the first grinding motor and the second grinding motor are started at the same time. The outer wall is simultaneously ground.

Description

technical field [0001] The invention relates to the technical field of pipeline spraying, in particular to a pipeline surface spraying equipment for water plant construction. Background technique [0002] Water pipes are pipes for water supply. Modern decoration water pipes are all built with buried walls. There are three types of water pipes. The first category is metal pipes, such as hot-dip cast iron pipes, copper pipes, stainless steel pipes, etc. with plastic lining. The second category is plastic composite metal pipes, such as steel plastic composite pipes, aluminum plastic composite pipes, etc. The third category is plastic pipes, such as PB pipes, PP-R pipes, etc.; [0003] In the past, pipes used for water supply were mainly cast iron pipes. Sand mold cast iron pipes are mainly used outdoors, while galvanized cast iron pipes are used indoors. However, after a few years of use, it is easy to produce a large amount of rust, which breeds bacteria and seriously endan...

AI Technical Summary

Problems solved by technology

However, after several years of use, it is easy to produce a large amount of rust and bacteria, which seriously endangers human health.

The state has stipulated that from June 1, 2000, sand casting pipe fittings and cold-dip galvanized cast iron pipes will be eliminated, the use of hot-dip cast iron pipes will be gradually restricted, and the use of aluminum-plastic composite pipes and new plastic pipes will be promoted. The pipes and fittings of the drinking water pipeline must be approved by the health department before they can be sold. As a water pipe, after several years of use, a large amount of rust will be generated in the pipe, and the yellow water flowing out will not only pollute the sanitary ware, but also mix with bacteria that grow on the rough inner wall , rust causes the heavy metal content in the water to be too high, which seriously endangers human health (the country has issued regulations to prohibit it from being used as a drinking water pipe)

[0004] The existing pipe surface spraying equipment for water plant construction has shortcomings. Before spraying the water pipes, the water pipes need to be polished, and there is a lack of grinding mechanism, and the existing grinding mechanism can only polish the surface of the water pipes. The interior cannot be polished, and only the outer wall of the water pipe can be sprayed when spraying
