Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of papermaking and relates to a miscellaneous pulp separation device at the end of a pulp remover. Background Art
[0002] Papermaking enterprises use slag removers to separate good pulp from impurities, but the processing capacity of slag removers has certain limitations. For example, impurity pulp will be continuously discharged from the end of the three-stage slag remover commonly used in papermaking workshops. However, some good pulp can be separated from these so-called impurity pulps. If they are discharged directly, part of the good pulp will be wasted, resulting in increased costs for the enterprise. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a device for separating impurities from pulp at the end of a pulp remover.
[0004] The utility model discloses a pulp separator at the end of a pulp remover, comprising a bracket and a slag discharge pipe, wherein a screw conveyor is arranged on the bracket, a driving assembly matched with the screw conveyor is arranged on the discharge end of the screw conveyor, a pulp groove corresponding to the slag discharge pipe is arranged at the feed end of the screw conveyor, and an overflow hole is arranged on the side wall of the pulp groove.
[0005] Working process or working principle:
[0006] When the slag remover sends the impurity slurry to the slurry tank through the slag discharge pipe, the slurry residue is physically precipitated to the bottom of the screw conveyor. After continuous separation, the good slurry reaches a certain height, flows out through the overflow hole and is recycled. The precipitated slurry residue is sent out of the equipment through the bolt conveyor to achieve the separation and recycling of the impurity slurry.
[0007] The driving assembly comprises a driving motor fixed on the screw conveyor, which is connected to the screw conveyor via a belt. The belt is used to realize the transmission of the material and also to prevent the driving motor from being damaged when the slurry residue blocks the screw conveyor.
[0008] The driving motor is also provided with a protective cover corresponding to the belt to prevent the pulp residue from contaminating the belt during delivery, thereby affecting the transmission and service life.
[0009] The angle between the screw conveyor and the ground is 15-20°.
[0010] The screw conveyor is a shaftless screw conveyor, and reducing the central shaft can reduce the situation where pulp residue blocks the screw conveyor.
[0011] The slurry tank is made of stainless steel.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] The utility model can effectively improve the separation of good pulp and pulp residue at the end of the slag remover, and the good pulp is recycled and reused, thereby saving costs; the pulp residue is screened out by the shaftless screw conveyor after physical precipitation, which saves electricity consumption and has lower cost than the traditional vibrating screen, and is simple, easy to disassemble and easy to clean.

[0017] Example 1
[0018] like Figure 1-2 As shown, the pulp separation device at the end of the pulp remover described in the utility model comprises a bracket 7 and a slag discharge pipe 6, a screw conveyor 3 is arranged on the bracket 7, a driving assembly matched with the screw conveyor 3 is arranged on the discharge end of the screw conveyor 3, a slurry groove 5 corresponding to the slag discharge pipe 6 is arranged at the feed end of the screw conveyor 3, and an overflow hole 4 is arranged on the side wall of the slurry groove 5; the driving assembly comprises a driving motor 2 fixed on the screw conveyor 3, the driving motor 2 is connected to the screw conveyor 3 through a belt 1, and the belt 1 is used to realize the transmission, and at the same time, it can also prevent the damage of the driving motor 2 caused by the slurry blocking the screw conveyor 3; the driving motor 2 is also provided with a protective cover corresponding to the belt 1, so as to prevent the slurry from polluting the belt 1 when it is sent out, thereby affecting the transmission and service life; the angle between the screw conveyor 3 and the ground is 15-20°; the screw conveyor 3 is a shaftless screw conveyor 3, and reducing the central axis can reduce the situation where the slurry blocks the screw conveyor 3; the slurry groove 5 is made of stainless steel.
[0019] Working process or working principle:
[0020] After the slag remover sends the impurity slurry to the slurry tank 5 through the slag discharge pipe 6, the slurry residue is physically precipitated to the bottom of the screw conveyor 3. After continuous separation, the good slurry reaches a certain height, flows out through the overflow hole 4 and is recycled. The precipitated slurry residue is sent out of the equipment through the bolt conveyor to achieve the separation and recycling of the impurity slurry.
[0021] The utility model can effectively improve the separation of good pulp and pulp residue at the end of the slag remover, and the good pulp is recycled and reused, thereby saving costs; the pulp residue is screened out by the shaftless screw conveyor 3 after physical precipitation, which saves electricity consumption and has lower cost than the traditional vibrating screen, and is simple, easy to disassemble and easy to clean.
