Abstract

The present invention provides a technical scheme of a cleaning method and a device for cantilevered screen meshes. The technical scheme is characterized in that an elastic frame is arranged under the cantilevered screen mesh; sticks are arranged on the elastic frame, or cleaning blocks are arranged between two screen bars; utilizing the vibration of the elastic frame in work drives the sticks or the cleaning blocks to hit the screen bars or to pick out the gaps between the screen bars to clean. The device utilizing the method is provided with at least two elastic frames at the lower surface of the cantilevered screen mesh, and the sticks are arranged on the elastic frames. The elastic frames can be vibration rods, or springs arranged on the side walls of screen plates. The sticks can be fixed or unfixed on the elastic frames. Cleaning blocks can be fixed on the sticks.

Description

A kind of cleaning plant of Cantilevered screen

Affiliated technical field:

What the present invention relates to is the industrial Cantilevered screen that is used to sieve material, especially a kind of cleaning plant of Cantilevered screen.

Background technology:

In the prior art, Cantilevered screen generally is to lean on the vibration of self to prevent by the obstruction that is sized material, but, sometimes when screening material in irregular shape or wet feed, just often stopped up between grating by individual other screening material, and the vibration of grating self can't be got rid of it, this just causes the sieve materials flow logical not smooth, and changed gap between grating, the problem that causes screening precision to reduce, and still do not have a kind of Cantilevered screen that can prevent to stop up so far, and the device that can clear up Cantilevered screen.

Summary of the invention:

Purpose of the present invention is exactly at the existing in prior technology deficiency, can prevent that the Cantilevered screen obstruction also can be to the technical scheme of its Cantilevered screen cleaning plant of clearing up and provide a kind of.

This programme is realized by following technical measures.Mainly include the Cantilevered screen that grating and built-in beam are formed, the characteristics of this programme have two to four elastic shelfs below described Cantilevered screen, described elastic shelf is the axis vibrating arm parallel with the grating axis, on this vibrating arm, be placed with a striking bar, this striking bar is not fixed on the vibrating arm, also has mousing-hook at the openend of each vibrating arm.The concrete characteristics of this programme also have, and fix a striking bar on the vibrating arm as elastic shelf, also are fixed with the cleaning piece on striking bar.Described cleaning piece is an axis and grating axis strip barred body in the same way, and its position is between two gratings.Described elastic shelf can also be the spring of being adorned on the sidewall of two sieve plates, and striking bar just is fixed on the spring.

According to as can be known to the narration of such scheme, because in this scheme, the elastic shelf that employing is made of vibrating arm or spring, fixing or a unfixed striking bar are arranged again on elastic shelf, as long as the elasticity of described elastic shelf is bigger, formed vibration when Cantilevered screen sieves work, just can make elastic shelf that vibration than large amplitude is arranged, the vibration of elastic shelf must drive striking bar and remove to hit grating as bob, make grating add the effect that striking bar is hit again when self vibrates, this can make and be clipped in more easily being excluded by the sieve material between grating.Especially in the out-of-work process of Cantilevered screen, the Cantilevered screen vibration frequency change, one resonant frequency identical with the striking bar frequency with elastic shelf will be arranged, this can make the amplitude of elastic shelf and striking bar bigger, so hitting dynamics maximum to grating, therefore, the material that is stopped up between easier removing grating.Yet, when by hit grating still can not remove stop up in the screen cloth serious when being sized material, this programme also has the cleaning piece of the rectangular clavate between two gratings, can get the grating gap by the material that sieved that the cleaning piece will be blocked between grating by force, the screen cloth of obstruction is cleaned out, so this programme is to prevent to stop up the more satisfactory device of Cantilevered screen, and structure is very simple.This shows that the present invention compared with prior art has outstanding substantive distinguishing features and obvious improvement, its implementation result also is conspicuous.

The specific embodiment:

For clearly demonstrating the technical characterstic of the described device of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by three specific embodiment.

First specific embodiment of the described device of this programme, be below the Cantilevered screen of forming by grating 1 and built-in beam 2, both sides and centre at built-in beam 2, three vibrating arms 4 as elastic shelf are housed altogether, on vibrating arm 4, place not a striking bar 3 fixing with vibrating arm 4, openend at vibrating arm 4 will have a mousing-hook 8, comes off to prevent striking bar 3.

Second specific embodiment of the described device of this programme, be below the Cantilevered screen of forming by grating 1 and built-in beam 2, two ends at built-in beam 2, vibrating arm 4 as elastic shelf respectively is housed, a striking bar 3 fixedly is housed on vibrating arm 4, and on striking bar 3, a cleaning piece 5 fixedly is housed again between per two gratings 1, the position of this cleaning piece 5 is the centres at any two gratings 1, and the shape of cleaning piece 5 is barred bodies of strip, when it moved to the position of grating 1, the axis of cleaning piece 5 will be substantially parallel with the axis of grating 1 and in the same way, and this just can guarantee to clear up piece 5 and can vibrate in the gap of grating 1.

The 3rd specific embodiment of the described device of this programme, be on the sidewall of both sides sieve plate 7 below the Cantilevered screen of forming by grating 1 and built-in beam 2, spring 6 as elastic shelf respectively is housed, a striking bar 3 fixedly is housed on spring 6, described spring 6 also can be installed on the sidewall paneling of screen box, and its effect is equivalent.
