A large-diameter center-driven hydraulic segmented automatic rake-lifting concentrator

Abstract

The invention discloses a large-diameter central transmission hydraulic segmental automatic rake-lifting concentrator, which includes a bridge frame, an upper center support, a driving device and a rake frame. A bridge frame is arranged at one end above the upper center support, and the driving device is installed on On the upper central support, a hydraulic station is arranged at one end of the driving device. The distance between the ends of the long rakes on both sides of the rake frame is 75 meters, so that the thickener can rotate and scrape the working diameter of 75 meters, which greatly improves the working range of the thickener. The rake frame of the thickener High-strength special structural steel is adopted, and the strength of the long and short rakes is improved to ensure that the durability of the rake frame is better when the long and short rakes are rotating and scraping materials; the model of the rake thickener is NXZ‑75, and the motor is three The equidistant paddle is driven by the crawler to move the material towards the concentration tank. On the one hand, it prevents the material from being blocked when it is scraped, and reduces the pressure of the thickener when scraping the material. On the other hand, it greatly improves the concentration. The scraping and feeding efficiency of the machine.

Description

technical field [0001] The invention relates to a concentrator, in particular to a large-diameter center-driven hydraulic segmented automatic rake-lift concentrator, which belongs to the technical field of rake-lift concentrator applications. Background technique [0002] The hydraulic three-cylinder five-drive automatic rake lifting center high-efficiency thickener NXZ-75 is mainly suitable for solid-liquid separation of industrial slurry. The treatment operation of waste residue, as well as the concentration and purification of solid slurry in industries such as water source and sewage treatment, that is, it is of great significance to improve the utilization rate of backwater, the concentration of underflow transportation and environmental protection; the thickener is the use of slurry The material particles in the slurry are naturally settled under the action of their own gravity to complete the concentration, that is, after the slurry enters the concentration tank, the ...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the width of the bridge frame on the existing rake concentrator is small, and the safety of the bridge frame is poor when it is in use. The material is easy to splash into the bridge frame and cause collision damage to the human body, and the area covered by the staff who can stand on the bridge frame for observation is too small; the efficiency of the thickener scraping the material to the center of the concentration pool and discharging it is low, and leads to different depths The material is not scraped out comprehensively and thoroughly; the working diameter of the existing thickener that can be rotated and scraped is small, the working range of the thickener is small, and the amount of real-time processing of the material is low; the overall strength of the rake frame on the thickener is low , which leads to poor firmness and durability of the rake frame when it is working; when the rake frame on the concentrator scrapes the materials, it cannot fully mix the materials of different layers and different densities, and the materials are easily blocked when they are scraped, resulting in the concentrator. The thickener is easy to be damaged when the pressure is too high when scraping the material; the working height of the rake frame cannot be flexibly adjusted up and down when the thickener is working, and the work automation is low. rake thickener
