Problems solved by technology

[0006] Features: Simple structure, widely used for material dehydration, desliming, and medium removal, with small processing capacity per unit area. According to the different particle sizes of screening materials, usually the screening treatment per unit area is 10-30t / (m 2 h); the screening efficiency is not high, generally around 65%
It is inconvenient to adjust the stroke angle of the vibrating screen, because the motor is directly connected to the main shaft of the vibrating screen, and the two vibrating shafts are arranged in steps, one high and one low, and the vibration direction angle is not easy to adjust
The structure of the screen frame is simple, only the connecting beams connect the left and right side plates. The beams are usually made of steel pipes, which have poor compressive and shear resistance. The screen frame has low strength, is easy to crack and fall apart, and has a short service life. It needs to be replaced in about two or three years

Embodiment Construction

[0028] The present invention will be further described below in conjunction with accompanying drawing.

[0029] see figure 1 , figure 2 and image 3 The elliptical linear vibrating screen includes a screen frame system. The screen frame system is composed of left and right side plates 11, side plate connecting beams 10, cross beams 9 and screen mesh 12. This embodiment adopts a double-layer screen, and can also be designed as a single-layer screen and Three layers of sieve. The screen frame system is supported by the vibrating screen support system 8, which is composed of 4 sets of support springs, and two sets of excitation devices are arranged on the upper part of the screen frame system.

[0030] Preferably, the structure of each group of excitation devices is as follows: the eccentric shaft 7 is rotatably installed on the screen frame system, the coupling shaft 3 is installed on the screen frame system with a seated bearing 4, and the coupling shaft 3 is connected to t...

Abstract

The invention discloses an elliptic linear vibrating screen. The elliptic linear vibrating screen comprises a screen frame system, wherein the screen frame system consists of left and right side plates (11), a side plate connecting beam (10), cross beams (9) and a screen mesh (12), the screen frame system is supported by a vibrating screen supporting system (8), and the upper part of the screen frame system is provided with two groups of vibration excitation devices. The elliptic linear vibrating screen disclosed by the invention has the advantages that the screening processing capacity is high, the screening efficiency is high, the stroke and a stroke angle can be conveniently adjusted, and the overhauling is convenient.

Description

technical field [0001] The invention relates to a vibrating sieve, in particular to an elliptical linear vibrating sieve, which is a classifying device for bulk and granular materials (such as ore, mineral powder, chemical raw materials, light industrial raw materials, etc.). Background technique [0002] At present, the screening equipment in the industry mainly includes: circular vibrating screen, linear vibrating screen, etc. The characteristics of the above screening equipment are as follows: [0003] (1) Circular vibrating screen: The motion trajectory of the screen frame is circular, which can be divided into two types according to the structure, one is the eccentric shaft type circular vibrating screen, and the other is the eccentric block type circular vibrating screen; The vibrating screen has only one set of excitation device. [0004] Circular vibrating screen features: simple structure, wide application range, medium processing capacity per unit area (about 20-3...
