Abstract
The invention discloses a pulverized coal vibrating screen, and aims to design a pulverized coal vibrating screen which is reasonable in structure and convenient in use. The invention adopts the technical scheme as follows: the pulverized coal vibrating screen comprises a power source and a rotating shaft, wherein the rotating shaft is arranged on a screen box; the rotating shaft is driven by the power source; supporting rods are arranged on the rotating shaft; a barrel-shaped screen plate is fixedly connected with the supporting rods. The pulverized coal vibrating screen is reasonable in structure, can effectively prevent pulverized coal from drifting away, is beneficial to the production environment and reduces production potential hazards.
Description
Technical field:
The present invention relates to vibratory sieve, particularly a kind of coal dust vibratory sieve that the employed coal dust of bf coal injection system is sieved of being adapted to.
Background technology:
Present coal dust vibratory sieve generally mostly is conventional design, because the employed coal dust of bf coal injection system is the fine powder after finish grinding, particle diameter is very little, adopt common screening mode, can cause coal dust to fly away phenomenon very serious, cause very big influence to environment for use, be unfavorable for that the environmental protection of producing carries out, simultaneously because also there is certain potential safety hazard in flying away of coal dust.
Summary of the invention:
The objective of the invention is to design a kind of coal dust vibratory sieve rational in infrastructure, easy to use.
Technical scheme of the present invention is, a kind of coal dust vibratory sieve, and it comprises power source, rotating shaft is characterized in that: be provided with rotating shaft at screen box, drive rotating shaft by power source, be provided with support bar in rotating shaft, cylindrical sieve plate is fixedlyed connected with support bar.
The present invention is rational in infrastructure, can prevent effectively that coal dust from flying away, and is conducive to production environment, has reduced production hidden danger.
Description of drawings:
Fig. 1 is structural representation of the present invention.
The specific embodiment:
Describe embodiment by reference to the accompanying drawings in detail: a kind of coal dust vibratory sieve, it comprises power source 1, rotating shaft 3, be provided with screen box 4 at screen frame (unit) 9, screen box is provided with charging aperture 6 and impurity outlet 8, is provided with discharge bucket 7 in the bottom of screen box, be provided with rotating shaft at screen box, drive rotating shaft by power source by shaft coupling 2, be provided with support bar 10 in rotating shaft, cylindrical sieve plate 5 is fixedlyed connected with support bar.
When the present invention uses, the present invention enters coal dust to be sieved from charging aperture, by sieving of cylindrical sieve plate, foreign material are discharged from impurity outlet, the coal dust that sieve is good is discharged from discharge bucket, whole screening process is all finished in airtight screen box, feed inlet and outlet can make things convenient for its relevant device rigid seal and is connected, and is that whole screening operation carries out under whole sealing status, and can makes total system carry out work under negative pressure state, thereby be difficult for taking place the situation that coal dust flies away, colleague's power source is selected fire-proof motor for use, also can effectively avoid potential safety hazard, and the present invention is rational in infrastructure, easy to use, result of use is better.
