Description

Dirt remover device

Technical Field

The utility model belongs to the technical field of cleaning tools, and particularly relates to a dirt remover device.

Background

The decontamination device is commonly used in drilling operation at home and abroad to remove mud adhered on a drill rod, and most of the drilling operation generally adopts the traditional disc type decontamination device made of integral rubber. The specific use mode is as follows: before the drill rod is ready to be drilled, the dirt remover is installed on the drill rod, and the inner diameter of the dirt remover is generally smaller than the outer diameter of the drill rod, so that the dirt remover can tightly wrap the drill rod by utilizing interference and rubber elasticity. When the drill rod is lifted to a certain height, the dirt remover can be limited below the drill plate and tightly attached to the bottom of the drill plate, and mud can be scraped clean after the drill rod adhered with the mud passes through the dirt remover, so that the operating environment on the drill floor is improved.

In actual use, the following disadvantages usually occur in the prior art stain removers:

1) the cleaner is easily deformed, thereby affecting the mud scraping effect. The reasons for this problem are: because the temperature of the slurry on the drill rod is high sometimes, the corrosivity of chemical components of the slurry is large sometimes, the dirt remover is a rubber product, the dirt removing is mainly finished by the interference and elastic contact between the inner circle of the dirt remover and the drill rod body, and once the dirt remover is subjected to high temperature and is easy to deform and elastically reduce due to foreign matters, the inner circle of the dirt remover becomes oval after deformation, so that the slurry on the drill rod cannot be completely removed, and the dirt removing effect is influenced;

2) the service life of the decontamination device is short. The traditional decontamination device is cast by an integral die, and generally after a plurality of wells are used, the traditional decontamination device is eliminated because the scraping effect is influenced by the rubber deformation and the elasticity reduction of a contact surface, so that resources are wasted and the atmospheric environment pollution is caused by mass production.

Therefore, there is a need in the art for a device for removing dirt from a surface of a substrate to solve the above problems.
