An illustrated view of an exemplary water pipe scale removal device is presented. The water pipe scale removal device includes a cutting head configured to be inserted into a pipe. In addition, the water pipe scale removal device includes a flexible drive cable in rotational communication with the cutting head. The cutting head includes a cylindrical shaft having three separated cutting members. Each separated cutting member includes eight elongated cutting blades arranged concentrically around the cylindrical shaft, while each cutting blade has a side cutting edge and a front cutting edge. The cutting blades are oriented at an acute angle to the central axis of the cylindrical shaft. The device is useful for removing scale buildup from a pipe.

Disclosed is a corrosion-resistant air preheater capable of slowing down dust deposit. The air preheater comprises a shell, an air inlet is fixedly formed in the side wall of the shell, an air outlet is fixedly formed in the side, away from the air inlet, of the shell, a flue gas through pipe is fixedly arranged on the inner side wall of the shell, rotating assemblies are arranged on the outer side wall of the flue gas through pipe, a flue gas inlet box is fixedly arranged at the top of the shell. According to the corrosion-resistant air preheater, an air pressure plate is pushed through the flue gas pressure intensity, and then the air pressure plate can descend. After the air pressure plate descends, rotating blades can rotate under the flowing effect of flue gas, then a movable rod rotates, and a scraping plate is further enabled to rotate.

A scraped surface heat exchanger comprising a heat exchange surface, a rotatable shaft, said shaft having at least one mounting means, and a sweeping element wherein said sweeping element comprises, a blade having at least one aperture for engaging with the mounting means such that the sweeping element is connected to the mounting means and characterised in that when the rotatable shaft is rotating relative to the heat exchange surface the sweeping element has substantially no movement relative to the rotating shaft and said sweeping element has substantially no contact with the inner surface of the heat exchanger.

This invention relates to an apparatus (10) for cleaning a helical member (52) such as a tabulator blade. The apparatus comprises opposed scrubbing brushes (32, 34) for removing deposits from the helical faces of the helical member (52) as it is passed between opposed bristles of the scrubbing brushes (32, 34). The opposed scrubbing brushes (32, 34) are mounted with the apparatus via a rotatable bearing (12) such that as the helical faces are reciprocated between the brushes, the continuously curving profile of the helical member (52) causes the brushes to rotate. Accordingly, the opposed scrubbing brushes (32, 34) maintain good contact with the helical surfaces thereby simplifying and improving the removal of deposits.
