Environmentally friendly ductile iron pipe inner wall grinding and cleaning equipment

Abstract

The invention relates to an environmentally-friendly ductile cast iron pipe inner wall grinding and cleaning apparatus. The environmentally-friendly ductile cast iron pipe inner wall grinding cleaning apparatus includes a pipe supporting and rotating device, a feeding device, a grinding and cleaning device. The environmentally-friendly ductile cast iron pipe inner wall grinding cleaning apparatus is characterized in that a vertical lifting bracket is arranged above the rack of the grinding and cleaning device; an upper supporting seat of the vertical lifting bracket is hinged to the bottom of a supporting rack through a rotating shaft; the output shaft of a grinding motor is connected with a transmission shaft where a grinding head is located through a universal joint and a middle transmission shaft; the front portion of the upper part of the supporting rack is provided with a supporting frame; the supporting frame is provided with a cantilever extending towards the grinding head; a dust removing pipeline is arranged on the cantilever; a plurality of shaft seats corresponding to the middle transmission shaft are fixed to the lower part of the cantilever; one end of the dust removing pipeline is connected with a dust remover; and a dust cover arranged above the grinding head is fixed to the other end of the dust removing pipeline. The environmentally-friendly ductile cast iron pipe inner wall grinding and cleaning apparatus has the advantages of reasonable design structure and safe and reliable use. With the environmentally-friendly ductile cast iron pipe inner wall grinding and cleaning apparatus adopted, the problems of low grinding efficiency, poor grinding quality, limitation on grinding caliber and environmental pollution of traditional inner wall cleaning equipment can be solved fundamentally.

Description

technical field [0001] The invention relates to pipe grinding equipment, in particular to an environment-friendly grinding and cleaning equipment for the inner wall of ductile iron pipes, and is also suitable for grinding and cleaning the inner walls of other metal pipes. Background technique [0002] In the traditional ductile iron pipe production process, the treatment of the inner wall of the pipe is relatively loose, and the requirements are not strict. The traditional inner wall cleaning equipment uses a motor to drive a flexible shaft, and the front section of the flexible shaft drives the grinding head to grind and clean the inner wall of the pipe. , The length of the flexible shaft is longer, generally 3.5-4 meters. It has the following problems: 1. Low grinding efficiency; 2. Poor grinding quality; 3. There are restrictions on the grinding caliber. The traditional single-station unit can only achieve the grinding of pipes with adjacent 3-4 specifications and caliber...
