Abstract

The invention discloses a sieve plate which comprises an annular sieve bar mounting base and sieve bars which are obliquely and uniformly distributed on the outer circle of the annular sieve bar mounting base along the circumferential direction. When the sieve plate is installed on the sieving equipment with the same floor area, the sieving equipment has more sieving area and distribution width; the opening structure with the small inside and the large outside of the screen bar is not easy to clamp materials, and has better screen penetration rate and moving speed of the materials on the screen surface; the sieve plate has the advantages of high material passing speed, small required vibration energy, reduced direct impact of the materials and the sieve bars, and remarkably prolonged service life of the sieve bars.

Description

Sieve plate

Technical Field

The invention belongs to the technical field of sieve plates, and particularly relates to a sieve plate.

Background

The vibrating screen mainly comprises a screen box, a vibration exciter, a supporting/hanging device, a motor and the like. The motor drives the main shaft of the vibration exciter to rotate through the belt, and the screen box is vibrated due to the action of centrifugal inertia force of unbalanced weights on the vibration exciter. The eccentric weight of the vibration exciter is changed, and different amplitudes can be obtained. However, in the actual use process, the feeding amount is changed greatly, the particle size of the material is also changed greatly, and the conventional bar sieve plate is easy to cause material blocking in the sieving process due to the fact that gaps between the bar sieve plate and the conventional bar sieve plate are always kept. In order to improve the vibrating screening effect, the existing bar type vibrating screen needs to be improved, and particularly, the bar type screen plate structure needs to be improved.

Disclosure of Invention

The invention solves the technical problem of providing the sieve plate which has reasonable structural design, longer service life and higher sieving efficiency.

The invention adopts the following technical scheme for solving the technical problems, and the sieve plate is characterized by comprising a circular sieve bar mounting base and sieve bars uniformly distributed on the outer circle of the circular sieve bar mounting base along the circumferential direction.

Further inject, there are a plurality of radial grating spliced eyes along the circumferencial direction equipartition on the ring shape grating mounting base, the grating grafting is fixed in the radial grating spliced eye of ring shape grating mounting base.

Further inject, the rectangle tubular structure that annular grizzly bar mounting base set up for the slope, has the grizzly bar spliced eye that a plurality of slopes set up along the circumferencial direction equipartition on the curb plate that this rectangle tubular structure is relative, and the grizzly bar is pegged graft and is fixed in the grizzly bar spliced eye of annular grizzly bar mounting base and the grizzly bar sets up to homonymy slope, and the opening gap between the adjacent grizzly bar presents the structure of big-end-up.

Further defined, the screen bars are bars.

Further, the same-direction inclination angle of the screen bars is 10-40 degrees.

Compared with the prior art, the invention has the following beneficial effects:

1. the screening device with the same floor area has more screening area and distribution width when the screening plate is installed.

2. The opening structure with the small inside and the large outside of the screen bar is not easy to block materials, and has better screen penetration rate and moving speed of the materials on the screen surface.

3. The sieve plate structure of the invention is light, has no redundant components, and greatly reduces the energy consumption of the sieving equipment.

4. The sieve plate has the advantages of high material passing speed, small required vibration energy, reduced direct impact of the materials and the sieve bars, and remarkably prolonged service life of the sieve bars.

Detailed Description

The technical scheme of the invention is described in detail by combining the attached drawings, and the sieve plate comprises a circular ring-shaped sieve bar mounting base 1 and sieve bars 2 uniformly distributed on the outer circle of the circular ring-shaped sieve bar mounting base 1 along the circumferential direction.

A plurality of radial sieve bar inserting holes 3 are uniformly distributed on the annular sieve bar mounting base 1 along the circumferential direction, and the sieve bars 2 are inserted and fixed in the radial sieve bar inserting holes 3 of the annular sieve bar mounting base 1.

The annular screen bar mounting base 1 is a rectangular pipe body structure which is obliquely arranged, a plurality of obliquely arranged screen bar inserting holes 3 are uniformly distributed in the circumferential direction on side plates which are opposite to the rectangular pipe body structure, the screen bars 2 are inserted and fixed in the screen bar inserting holes 3 of the annular screen bar mounting base 1, the screen bars 2 are obliquely arranged towards the same side, and an opening gap between every two adjacent screen bars 2 is of a structure with a small inside and a large outside.

The screen bars 2 are bars; the same-direction inclination angle of the screen bars 2 is 10-40 degrees.

In the using process, the screening equipment with the same floor area has more screening area and distribution width when being installed with the screening plate; the opening structure with the small inside and the large outside of the screen bar is not easy to block materials, and has better screen penetration rate and moving speed of the materials on the screen surface. (ii) a The sieve plate has a light structure, does not have redundant parts, and greatly reduces the energy consumption of sieving equipment; the sieve plate has the advantages of high material passing speed, small required vibration energy, reduced direct impact of the materials and the sieve bars, and remarkably prolonged service life of the sieve bars.

While there have been shown and described what are at present considered the fundamental principles of the invention, its essential features and advantages, the invention further resides in various changes and modifications which fall within the scope of the invention as claimed.
