High-efficiency water-injection mud scraper

Abstract

The invention discloses a high-efficiency water-injection mud scraper. The mud scraper comprises a working bridge, a driving mechanism, a rotation shaft, a mud-scraping mechanism and a high-pressure water gun, wherein the mud-scraping mechanism comprises an installation rack and a scraper blade which is fixedly arranged on the installation rack, mud-breaking mechanisms are arranged on the front and reverse sides of the scraper blade, and the mud-breaking mechanisms comprise strip-shaped rods and cross racks which connect the strip-shaped rods and the installation rack; cavities are formed in the strip-shaped rods, and jet orifices are formed in the side walls of the strip-shaped rods; the high-pressure water gun comprises a high-pressure plunger pump, a power device and jet gun heads; the high-pressure plunger pump and the power device are both fixedly arranged on the working bridge, the jet gun heads are fixedly arranged in the cavities, and outlets of the jet gun heads are located in the jet orifices. According to the mud scraper, the jet gun heads are used for spraying high-pressure water to a mud layer, so that sludge which is deposited on the bottom of a pool is diluted, the driving force which is required by the rotation of the rotation shaft is greatly reduced, the energy consumption of the whole machine can be greatly reduced, and the service life of the mud scraper can be greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a water injection type high-efficiency mud scraper. Background technique [0002] The mud scraper is mainly used in circular sedimentation tanks with large diameters in urban sewage treatment plants, waterworks and industrial wastewater treatment to remove the sludge settled at the bottom of the tank. After sedimentation at the bottom of the pool, it is squeezed and compacted by gravity, causing the middle and lower layers of the sludge at the bottom of the pool to have a high viscosity, so that when the sludge scraper is working, it is subjected to a very large resistance and is easy to break. It is urgently needed Improve. Contents of the invention [0003] Based on the technical problems in the above-mentioned background technology, the present invention proposes a water-injection high-efficiency mud scraper. [0004] The invention proposes a water-injection high-...
