Embodiment Construction

[0014] In order to clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation modes and in conjunction with the accompanying drawings.

[0015] As shown in Fig. 1, the present invention comprises screen bar and beam frame 1 made of elastic metal, and every two of said screen bars are set up vertically up and down, and one end of the screen bar is perpendicular to beam frame 1 and is fixed on beam frame 1, the other end is in a free state, and each group of sieve bars is arranged on the beam frame 1 in parallel according to the set interval.

[0016] As shown in Figure 2, there is a certain gap between the two vertical screen bars of the present invention, and they can also be close together up and down. Among the two vertical sieve bars, the cross section of the upper sieve bar 2 is polygonal, and the cross section of the lower sieve bar 3 is circular. The upper sieve bar 2 is elastic squ...

Abstract

The invention relates to a screen netting of auto-cleaning screen, which belongs to the technology of industrial screen separation. The invention comprises a screen bar and a beam frame made of elastic metal. Every two screen bars are considered as a unit that is vertically up-and-down arranged. One end of the screen bar is perpendicular to and fixed on the beam frame. And the other end is in free condition. Every unit of the screen bar is arranged on the beam frame in parallel at predefined space. The invention can automatically clear meshes that are blocked by critical particles and greatly prolong the service life of the screen bar.

Description

Technical field: [0001] The invention relates to a screen sheet of a self-cleaning screen, belonging to the technical field of industrial screening. Background technique: [0002] In the prior art, the rod screen is a screen composed of a single metal rod with a certain length arranged at a certain distance and one end fixed on a rectangular beam frame. The gap between adjacent rods is the mesh size. In vibratory sieving, the rods vibrate randomly. Particles that are much smaller than the mesh size can pass through the screen smoothly, and particles that are much larger than the mesh size cannot pass through, and when the critical particle is close to the mesh size, it is difficult to pass through the screen or be bounced, resulting in blockage of the mesh. The rod screen with better effect is the self-cleaning screen with the patent number ZL01262004.1 applied by the applicant. Particle clogging is reduced. However, in inverse proportion to the improvement of screening ...
