Description

Technical Field

[0001] The utility model relates to the technical field of vibration dehydration, in particular to a vibration dehydration screen. Background Art

[0002] Vibrating dewatering screen is a kind of dewatering equipment. It is also called sand and gravel dewatering screen, mining dewatering screen, coal slime dewatering screen, tailings dewatering screen, high-frequency dewatering screen, etc. At present, all the excitation structures of dewatering screens on the market can be divided into two types, one is the side plate type exciter, and the other is the conduction type exciter through the excitation beam;

[0003] Both excitation methods have their own technical defects: the side plate type vibrator is installed in the middle of the side plate, close to the material, and the vibrator is easily damaged by the material; the excitation force of the excitation beam conduction type vibrator needs to be transmitted through the excitation beam, which will cause the excitation force loss during the transmission process. At the same time, the excitation beam is easy to break during use, affecting production. Both methods have their own technical defects, and a more efficient and reasonable excitation method is urgently needed. For this reason, we propose a vibrating dewatering screen. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a vibrating dewatering screen, which absorbs the advantages of the two structures of side plate excitation and excitation beam excitation, retains the original excitation beam, and adds an exciter sub-beam. By transferring the installation position of the excitation source to the upper middle part of the side plate, the center line of the excitation source coincides with the center line of the side plate, which is more conducive to the vibration effect on the screen box as a whole. The exciter sub-beam is used to improve the structural stability of the excitation beam relative to the overall screen box and improve the transmission efficiency; by raising the excitation source, the erosion of the material on it is overcome, and at the same time the entire screen box is directly excited, reducing the loss of the excitation force, and also has a reliable polyurethane wave screen plate, and the triangular screen surface greatly increases the screening area, thereby increasing the screening processing capacity and processing effect, which can effectively solve the problems in the background technology.

The transmission shaft is used to keep the main eccentric blocks on the front and rear sides rotating at the same speed, thereby ensuring that the effects of the vibration sources on both sides are uniform. The vibrator is used for the installation and fixation of the bearing chamber, and by supporting the bearing chamber, the height of the vibration source is increased, overcoming the erosion of the material on it, while directly exciting the entire screen box and reducing the loss of exciting force. The dehydration unit increases the screening area through a triangular three-dimensional structure, thereby increasing the screening processing capacity and processing effect.

[0010] Furthermore, the vibrator assembly also includes a vibrator subbeam, side panel reinforcements and a shaft protector. A square vibrator subbeam is fixedly connected to both the front and rear ends of the vibrator beam. The two vibrator subbeams are respectively clamped on the outer sides of the side panels. Four side panel reinforcements are fixedly connected to the middle parts of the outer sides of the two side panels.
