Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the slurry inlet pipe 1, the slurry outlet pipe 2, the cylinder 3, the slag discharge pipe 4, the cover body 5, the settling tank 6, the discharge pipe 7, the fixture block 8, the slurry overflow screen 9, the settling chamber 10 and the partition plate 11.

Example (b):

as shown in fig. 1 and 2, the paper-making slag remover comprises a cylinder 3, wherein a pulp inlet pipe 1 is communicated with the right side of the top of the cylinder 3, a pulp outlet pipe 2 is communicated with the top of the cylinder 3, a slag discharge port is formed in the bottom of the cylinder 3, and a slag discharge pipe 4 is communicated with the slag discharge port. A sedimentation tank 6 is arranged below the cylinder body 3, a cover body 5 is hinged to the top of the sedimentation tank 6, and the slag discharge pipe 4 is detachably connected with the cover body 5. Specifically, the scum pipe 4 is the hose, and the free end of scum pipe 4 splices and is fixed with two fixture blocks 8, and fixture block 8 is made by magnet, and lid 5 adopts the material that can be adsorbed by magnet, makes like iron, and two fixture blocks 8 use the axis of scum pipe 4 to set up as the symmetry line symmetry, and it has the connector to open on the lid 5, and the connector edge is opened has two and is used for the draw-in groove with fixture block 8 complex. The clamping block 8 is inserted into the connecting port from the clamping groove and then the slag discharging pipe 4 is rotated, so that the clamping block 8 is staggered with the clamping groove, the clamping block 8 is sucked with the cover body 5 from the inside, and the slag discharging pipe 4 can be connected with the cover body 5.

The vertical a plurality of baffles 11 that are fixed with in the settling tank 6, the quantity of baffle 11 is two in this embodiment, and two baffles 11 separate into three settling chamber 10 with settling tank 6, arranges sediment pipe 4 and left settling chamber 10 intercommunication, and settling chamber 10 bottom intercommunication on right side has discharging pipe 7, seals ejection of compact screen cloth (not shown in the figure) in the discharging pipe 7. A slurry overflow port for slurry to overflow is reserved between the two partition plates 11 and the top of the settling tank 6, a slurry overflow screen 9 is sealed at the slurry overflow port, the diameters of meshes of the slurry overflow screen 9 are sequentially reduced from left to right, and the diameter of the mesh of the slurry overflow screen 9 on the left side in the embodiment is larger than that of the mesh of the slurry overflow screen 9 on the right side. The excessive thick liquid screen cloth 9 can be dismantled with baffle 11 and be connected, and is concrete, and open at baffle 11 top has vertical spread groove, and excessive thick liquid screen cloth 9 can the joint in the spread groove, and lid 5 covers the back and can offset with excessive thick liquid screen cloth 9.

The specific implementation process is as follows:

after aligning fixture block 8 and draw-in groove, insert the connector with scum pipe 4 in, rotate scum pipe 4 a little after inserting and make fixture block 8 and draw-in groove stagger, fixture block 8 adsorbs on lid 5 from inside, realizes being connected of scum pipe 4 and lid 5 from this. During deslagging, slurry enters the upper part of the barrel 3 from the slurry inlet pipe 1 along the tangent line of the inner wall of the barrel 3, and under a certain flow speed and pressure, the slurry rotates and runs forcefully along the inner wall of the barrel 3 to generate centrifugal force, and because the relative density of waste residues is high and the centrifugal force is also high, the waste residues are thrown to the inner wall of the barrel 3, then run downwards along the inner wall of the barrel 3 under the action of gravity, and finally are discharged into the settling tank 6 along the slag discharge pipe 4.

A low-pressure area is formed at the axial center of the cylinder 3 due to centrifugal action, the relative density of the slurry is low, the slurry gradually moves inwards to the low-pressure area in the process of downward rotating motion, and rotates upwards along the center of the cylinder 3, and finally is discharged from the slurry outlet pipe 2 at the top of the cylinder 3.

The waste slag is discharged into the left settling chamber 10 through the slag discharge pipe 4, and is settled in the settling chamber 10, impurities in the waste slag are precipitated at the bottom of the settling chamber 10, and slurry is separated out at the upper layer. When the left settling chamber 10 is filled, the slurry overflows from the slurry overflow port on the right side of the settling chamber 10 into the middle settling chamber 10, thereby performing secondary settling. After the middle settling chamber 10 is filled with slurry, the slurry overflows into the settling chamber 10 on the right side and enters and exits for the third settling, so that impurities and slurry in waste residues are separated, finally, slurry without impurities is obtained in the settling chamber 10 on the right side, and the separated slurry can be discharged through the discharge pipe 7 for recycling. Because the pulp overflowing screen 9 is arranged at the pulp overflowing opening, when the pulp overflows from one settling chamber 10 to the other settling chamber 10, impurities can be filtered by the pulp overflowing screen 9 and cannot be carried into the next settling chamber 10, and the separation effect of the impurities and the pulp in the waste residue is improved.

When the impurities in the settling box 6 need to be treated or the settling box 6 and the pulp overflowing screen 9 are cleaned or maintained, the slag discharge pipe 4 is detached from the cover body 5, the cover body 5 is opened, the settling box 6 can be treated, and the pulp overflowing screen 9 can be maintained and replaced by pulling out the pulp overflowing screen 9 from the partition plate 11.

Discharged waste residue is retrieved to this embodiment to subside through a plurality of settling chambers 10, the effectual thick liquids that carry the waste residue have been separated out, and the thick liquids that separate out can recycle, have avoided the thick liquids that directly discharges the waste residue and cause to run off.

The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
