Description

Dead weight type scraper for cleaning oil sludge Technical Field The invention relates to the technical field of oil sludge cleaning, in particular to a dead weight scraper for cleaning oil sludge. Background The scraper is a tool mainly used for cleaning the surface of the steel belt or the deviation correcting roller. In the metal processing process, the surfaces of the steel belts or the deviation correcting rollers may be stained with impurities such as greasy dirt, scrap iron, dust and the like, and the impurities not only affect the production efficiency, but also can cause the problem of product quality. In order to ensure production quality and improve production efficiency, doctor blades are widely used in the metal working industry. Reasonable in design's scraper can laminate the steel band better or rectify the roller surface, ensures the clearance effect. In the prior art, a dead weight scraper is generally adopted, and the scraper is made to be close to a steel belt or a deviation correcting roller as much as possible through a counterweight, so that the cleaning effect of the scraper is improved, but the method has defects, such as the fact that the steel belt is waved at two rolling ends of a rolling mill, the two ends of the steel belt and the middle of the steel belt are not on the same plane, at the moment, the dead weight scraper cannot achieve the oil removing effect, and the steel belt is possibly broken. Disclosure of Invention The invention aims to provide a dead weight scraper for cleaning oil sludge, which can enable the scraper to be better attached to a steel belt or a deviation correcting roller, so that the impurity cleaning effect is ensured. The base scheme comprises a long shaft, wherein a plurality of clamp bodies are arranged in the middle of the long shaft and used for fixing and clamping blades, each clamp body is provided with a blade, a telescopic device is arranged between each clamp body and each blade and used for adjusting the relative position between the clamp body and each blade, dead weight devices are arranged at two ends of the long shaft and comprise hanging rods and balancing weights, the hanging rods are perpendicular to the long shaft and connected with the long shaft, and the balancing weights are detachably connected to the ends of the hanging rods through nuts. The beneficial effect of basic scheme, this technical scheme is provided with a plurality of anchor clamps bodies at the major axis, if damage appears in one of them anchor clamps body or blade can change pertinently, is convenient for maintain simultaneously the cost is reduced. Based on this design, this scraper can form different angles at every anchor clamps body when handling irregular impurity to make every anchor clamps body all can laminate with the steel band or rectify the roller better, guarantee the cleaning performance of impurity such as greasy dirt. Meanwhile, dead weight devices are further arranged at two ends of the long shaft, and generate downward force under the action of gravity, so that the clamp body is driven, the blades can be tightly attached to the surface of the steel belt, and the cleaning effect is guaranteed. As a preferred implementation scheme, the clamp body is connected with the long shaft in a sliding manner and is fixed through screws.
