Problems solved by technology
During the operation, it was found that the contact surface between the rake frame and the pulp is large, and the rake frame pushes the pulp to rotate during operation, resulting in a rotating material flow. The upper part of the rake frame is seriously hung, the running resistance is large, and the reactive power consumption is high.
The scraper is directly welded under the rake frame, and the distance from the bottom of the pool cannot be adjusted during on-site installation

Embodiment Construction
[0031] The present invention will be further described below in conjunction with the accompanying drawings.
[0032] The present invention includes a rake frame 1, a scraper connecting rod 2, a scraper 3, a plug plate 4 at the end of the rake frame, and the like.
[0033] Such as figure 1 , 2 As shown, the rake frame 1 is a hollow truncated pyramid made of steel pipes with a triangular cross-section. combine Figure 5 As shown, at the three apexes of the triangle, arrange a triangular section rake frame apex main steel pipe 11 with a circular section, two triangular section rake frame lower chord surface main steel pipes 12, triangular section rake frame apex main steel pipe 11, two triangular section rake The triangular cross-section rake rack secondary steel pipes 13 with circular cross-sections are used to connect between the main steel pipes 12 on the lower chord surface of the frame. The end of rake frame 1 is blocked with rake frame end plug plate 4, avoids corrosio...

The invention discloses a scrapping-mud raker of a center raker thickener. The problem that an existing rake frame is large in operating resistance, and the position of a scrapping plate is inconvenient to adjust is solved. The scrapping-mud raker of the center racker thickener is characterized in that a rake frame is a hollow cutting back pyramid which is composed of a steel pipe, and the section of the rake frame is in a shape of a triangle or a rectangle or the combination of the triangle and the rectangle. The vertex position of the section is provided with main steel pipes, vice steel pipes are used to connect the main steel pipes. The scrapping plate is placed below the rake frame, and the scrapping plate and the rake frame are connected through scrapping plate connecting rods. The scrapping plate connecting rods are steel pipes, one ends of the steel pipes penetrate through holes arranged in the main steel pipes and are welded on the main steel pipes, the other ends of the steel pipes are provided with grooves to clamp the scrapping plate and are welded with the scraping plate. A cutting back pyramid structure which is composed of round steel pipes is large in strength, low in operating additional resistance and low in energy consumption. The scrapping plate and the rake frame are connected through the scrapping plate connecting rods with the grooves, so that the position of the scrapping plate is easy and convenient to adjust.
Description
technical field [0001] The invention relates to a mud scraping rake of a concentrator, more precisely to a mud scraping rake of a center rake thickener. Background technique [0002] Thickening and settling is a continuous process, and the material settled in the thickening tank is scraped to the central mud bucket by the mud scraper of the thickener. In order to meet the requirements of mud scraping, reduce resistance, easy installation and scraper adjustment during installation, it is required that the mud scraping rake of the concentrator should have sufficient strength and at the same time have low running resistance and be easy to install and adjust. The strength is to ensure that the rake will not be damaged when scraping mud, and the small resistance can reduce the energy consumption of the thickener. It is easy to install and adjust because the thickening tank is generally a concrete structure, and the slope of the bottom of the tank has a large deviation from the th...
