Sweeping device for inner wall of FRPP pipe fitting

Abstract

The invention discloses a sweeping device for an inner wall of an FRPP pipe fitting. The sweeping device is characterized in that a roller carrier is fixed on a basic shaft, three rollers are elastically supported on the roller carrier, a first spring and a walking carrier are arranged on the basic shaft in a sleeving manner, the walking carrier props the first spring against the roller carrier, three walking wheels are rotationally connected to the walking carrier, a sweeping brush is rotationally connected to the basic shaft, a driving mechanism is fixed on the basic shaft and simultaneouslydrives the sweeping brush and the three walking wheels to rotate, and a spraying system is fixed on the basic shaft and located on one side of the roller carrier. Walking and sweeping functions can be realized by one motor, so that the structure is simplified and the space is saved. The rollers and the walking wheels can be compressed, so that the sweeping device is applicable to to-be-cleaned pipe fittings with different pipe diameters. The cleaning brush sweeps the inner walls of the pipe fittings to be cleaned and clears away sticky materials on the pipe walls. The spraying mechanism is connected to the hose, the hose is connected to a water pump, and a cleaning fluid is sprayed to realize spray cleaning of the pipe walls for dirt removal.

Description

Technical field: [0001] The invention relates to a cleaning device for the inner wall of FRPP pipe fittings. Background technique: [0002] FRPP pipe (glass fiber reinforced polypropylene pipe) is produced with glass fiber modified polypropylene material treated with coupling agent, according to HG20539-92 standard, specification DN15-DN1500mm, nominal pressure 0.4-1.0MPa, corrosion resistance, high temperature resistance, High pressure resistant, hygienic and non-toxic, recyclable, suitable for corrosive liquid transportation (such as acid and alkali) and municipal water supply and drainage systems. It has excellent impact resistance and tensile strength, light weight, convenient installation and maintenance. The existing hot air welding connection, hot melt connection and flange connection are widely used in chemical industry, chemical fiber, chlor-alkali, dye, water supply and drainage, food , medicine, sewage treatment, electrolysis and other industries.

AI Technical Summary

Problems solved by technology

[0003] FRPP pipes are very common in the chemical industry. They can be used to transport gas, liquid or devices with solid particles. After a long time of use, the inner wall of the pipe made of FRPP pipes used to transport gas or solid particles will be laminated. There are many solid particles or dust particles, and the pipeline needs to be cleaned regularly. However, due to the long length of the pipeline and the inconvenient disassembly, etc., the manual cleaning workload is large, and the internal cleaning is extremely inconvenient and difficult to clean. Clean up, therefore, it is necessary to improve the existing technology to solve the deficiencies of the existing technology
