Steel surface rust removing device

Abstract

The invention discloses a steel surface rust removing device which comprises a sand-blasting drum, a cleaning head and a drying part, wherein the cleaning head is arranged on one end of the sand-blasting drum, and the drying part is arranged on one side of the cleaning head; the cleaning head is connected with a water tank through a pipeline, and a filter device is arranged between an inlet and an outlet of the water tank; the filter device comprises a magnetic filter, a backwashing filter, a high-precision filter and a cooler, a water pump is connected with an inlet of the magnetic filter through the pipeline, a drain outlet of the magnetic filter is connected with a drain tank through a drain pipe, and a water outlet of the magnetic filter is connected with an inlet of the backwashing filter through the pipeline; a drain port of the backwashing filter is connected with the drain tank through the drain pipe, and the water outlet of the backwashing filter is connected with an inlet of the high-precision filter through a water discharge pipe; and an outlet of the high-precision filter is connected with an inlet of the cooler, and an outlet of the cooler is connected with the water tank through the pipeline. With the steel surface rust removing device, water can be recycled, water in the water tank can keep clean all the time, and thus, a sand blasting rust removing effect is ensured.

Description

technical field [0001] The invention relates to a surface rust removal device, in particular to a steel surface rust removal device. Background technique [0002] The surface derusting device for steel includes a sandblasting cylinder, a cleaning head, and a drying section. One end of the sandblasting cylinder is provided with a cleaning head, and one side of the cleaning head is provided with a drying section. [0003] The existing sandblasting cylinder has an integrated structure. Due to the impact of sandblasting during the sandblasting process, it is easy to cause wear to the sandblasting cylinder. Once worn, the entire sandblasting cylinder needs to be replaced, resulting in an increase in maintenance cost and difficulty. The existing cleaning head only has two cleaning pipes, the upper and the lower, resulting in incomplete cleaning. The drying rags in the existing drying section are unevenly distributed and the appearance is messy. [0004] In addition, during the ...

AI Technical Summary

Problems solved by technology

[0003] The existing sandblasting cylinder has an integrated structure. Due to the impact of sandblasting during the sandblasting process, it is easy to cause wear to the sandblasting cylinder. Once worn, the entire sandblasting cylinder needs to be replaced, resulting in an increase in maintenance costs and difficulty.

The existing cleaning head only has two cleaning pipes up and down, resulting in incomplete cleaning

The existing drying section has uneven distribution of drying rags and a messy appearance

[0004] In addition, during the sandblasting process, the water in the water tank will gradually become turbid, and there will be too many impurities, which will affect the effect of sandblasting and rust removal.
