Description

Coal slurry screening plate column

Technical field

The utility model relates to screening plant, and be more particularly a kind of coal slurry screening plate column, coal slurry sieves successively through each layer overflow sieve plate, overflow sieve plate is less than the coal grain of screen size by overflow sieve plate.

Background technology

The method of current coal slurry screening is that coal slurry carries out single screening by individual layer screen cloth, sieves insufficient, and part small particle diameter coal particle has little time just to be discharged with defective coal slurry form by screen cloth.

Summary of the invention

In order to the method solving the screening of existing coal slurry is that coal slurry carries out single screening by individual layer screen cloth, sieve insufficient, part small particle diameter coal particle has little time by screen cloth just with the problem that defective coal slurry form is discharged, the utility model provides a kind of coal slurry screening plate column, coal slurry can be made to flow to opposite side by the slurry landing pipe sieving board-like inner wall of tower near coal slurry from overflow sieve plate side slowly sieve, increase coal slurry and overflow sieve plate contact area, and slowly to be flowed screening by each layer overflow sieve plate successively, add the screen cloth number of plies and screening number of times.

The technical solution adopted for the present invention to solve the technical problems is: it is provided with stock inlet at plate column top, plate column top seal, plate column internal welding is connected to the overflow sieve plate of each layer circle, overflow sieve plate there is sieve aperture, overflow sieve plate tail end has slurry landing pipe, odd-level and even level slurry landing pipe are distributed in the both sides of plate column respectively, coal slurry can be made to flow to opposite side from the side of every layer of overflow sieve plate, increase coal slurry and overflow sieve plate contact area, overflow sieve plate tail end and slurry land between pipe and are provided with overflow baffle, qualified coal slurry buffer barrel is arranged at plate column bottom, circular sieving plate is again tiltedly installed with between plate column and qualified coal slurry buffer barrel, above the side that sieving plate absolute altitude is low again, defective coal slurry grout outlet is installed, qualified coal slurry buffer barrel sealed bottom, qualified coal slurry buffer barrel grout outlet is installed on bottom qualified coal slurry buffer barrel, under bottom qualified coal slurry buffer barrel, vibrator at the bottom of tower is installed.

The utility model has the following advantages compared with existing coal slurry material sieving technology: the method that existing coal slurry sieves is that coal slurry carries out single screening by individual layer screen cloth, sieve insufficient, part small particle diameter coal particle has little time by screen cloth just with the problem that defective coal slurry form is discharged, the utility model provides a kind of coal slurry screening plate column, coal slurry can be made to flow to opposite side by the slurry landing pipe sieving board-like inner wall of tower near coal slurry from overflow sieve plate side slowly sieve, increase coal slurry and overflow sieve plate contact area, and slowly to be flowed screening by each layer overflow sieve plate successively, add the screen cloth number of plies and screening number of times.
