Problems solved by technology

[0003] In the process of chemical construction, the metal pipes used to transport chemical fluid media need to be polished and derusted on the inner wall before installation to ensure that the interior is clean and rust-free. For large-diameter metal pipes, construction workers mainly enter the pipes Grinding with an internal hand-held grinding device is labor-intensive and the grinding efficiency is low. For this reason, a rust removal and cleaning device for the inner wall of metal pipelines in chemical construction is now provided to solve the above technical problems

Embodiment 1

[0022] See Figure 1-4 , A derusting and cleaning device for the inner wall of a metal pipeline for chemical construction, comprising a support frame 1, a drive motor 2 fixed on the support frame 1, a drive shaft 29 is fixed coaxially on the output shaft of the drive motor 2, and a grinding mechanism is connected to the drive shaft 29 for transmission , The grinding mechanism includes a dual-axis motor 6. The two output shafts of the dual-axis motor 6 are coaxially fixed with a threaded shaft I7 and a threaded shaft II17 with opposite thread directions. The threaded shaft I7 and the threaded shaft II17 are respectively threaded with threaded sleeves. The pipe I30 and the threaded sleeve II15 are hinged on the threaded sleeve I30 and the threaded sleeve II15 via a support rod 14 with a grinding plate 3 abutting against the inner side wall of the metal pipe 5. Two transmission rods 16 are passed through the threaded sleeve II15, and the two ends of the transmission rod 16 are res...

Embodiment 2

[0026] In order to further improve the efficiency of grinding and removing rust on the inner wall of the metal pipe 5, on the basis of embodiment 1, a rotating shaft I11 and a rotating shaft II24 are arranged horizontally on the support frame 1, and the rotating shaft I11 and the rotating shaft II24 are respectively sleeved The driving pulley 28 and the driven pulley 25 are fixed, the driving pulley 28 and the driven pulley 25 are sleeved with a belt 18, and the rotating shaft I11 and the rotating shaft II24 are sleeved and fixed with the outer wall of the metal pipe 5. The connected supporting roller 12, the drive shaft 29 and the rotating shaft I11 are drivingly connected with a pulley mechanism 13.

[0027] Through the above arrangement, when the drive shaft 29 rotates, the drive shaft 29 drives the rotating shaft I11 to rotate together with the driving pulley 28 through the pulley mechanism 13, and the driving pulley 28 drives the driven pulley 25 to rotate through the belt 18...

Abstract

The invention discloses a rust-removal cleaning device for the inner wall of a chemical construction metal pipeline, and relates to the technical field of chemical construction. The rust-removal cleaning device comprises a supporting frame, a driving motor is fixed to the supporting frame, a driving shaft is coaxially fixed to an output shaft of the driving motor, a threaded shaft I and a threadedshaft II which are opposite in thread rotating direction are coaxially fixed to two output shafts of a double-shaft motor correspondingly, and polishing plates abutting against the inner side wall ofthe metal pipeline are hinged to a threaded sleeve I and a threaded sleeve II through supporting rods. According to the rust-removal cleaning device, the driving motor drives the driving shaft to rotate, thus a polishing mechanism conducts rotary polishing on the inner wall of the metal pipeline, meanwhile, a supporting rotary roller drives the metal pipeline and the polishing mechanism to rotatein the reverse direction, thus relative displacement of the polishing plates and the metal pipeline is greatly increased, the polishing efficiency is higher, the arranged polishing mechanism can adjust the polishing radius through the double-shaft motor, thus the metal pipelines with the different inner diameters are efficiently polished, adjusting is convenient, and polishing applicability is high.

Description

Technical field [0001] The invention relates to the technical field of chemical construction, in particular to a rust removal and cleaning device for the inner wall of a metal pipeline in a chemical construction. Background technique [0002] Chemical industry is the abbreviation for "chemical process", "chemical industry", and "chemical engineering". Any technology that uses chemical methods to change the composition or structure of a substance or synthesize a new substance is a chemical production technology, that is, a chemical process, and the resulting product is called a chemical or chemical product. In the beginning, these products were produced in handicraft workshops, and later evolved into factories, and gradually formed a specific production industry, the chemical industry. Chemical engineering is a science that studies the common laws of the production process of chemical products. The relationship between humans and chemical industry is very close. Some chemical pr...
