Water-injecting efficient mud scraper with automatic water injection

Abstract

The invention discloses a water-injecting efficient mud scraper with automatic water injection, comprising a service bridge, a driving mechanism, a rotary shaft, a mud scraping mechanism, and an end cover, wherein the mud scraping mechanism includes a mounting frame and a scraper plate, front and back sides the scraper plate are provided with water injection guns, each water injection gun has a control switch that controls its turning-on / turning-off; a protective cover is arranged outside the water injection guns and includes a main portion and an end portion, and the main portion has a chamber for mounting the water injection guns; the end portion is provided with a main linear chamber and an auxiliary linear chamber, a compression spring is mounted at the bottom of the main linear chamber, and the auxiliary linear chamber is communicated with a cavity of the main portion; one end of the end cover is provided with a main protrusion portion and an auxiliary protrusion portion; the main protrusion portion extends into the main linear chamber and abuts to the compression spring; the auxiliary protrusion portion is extended from the auxiliary linear portion into the cavity and connected with the control switches. The water-injecting efficient mud scraper is low in energy consumption and long in service life and allows the water injection guns to automatically turned on / off.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a water-injection high-efficiency mud scraper for automatic water injection. 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, resulting in a high viscosity in the middle and lower layers of the sludge at the bottom of the pool, 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 background technology, the present invention proposes a water-injection high-efficiency mud scraper with automatic water injection. [0004] ...
