Abstract
The utility model relates to a processing device for paper pulp before the paper pulp is used on a paper machine, which is vertical and uses centrifugal force to remove sand (slag) impurities in the paper pulp. The utility model comprises the working part of a conical cylinder, a pulp inlet part arranged on an upper part in the tangential direction, a good pulp outlet part on an upper end, and a sand (slag) outlet on a lower end. The inner surface of the conical cylinder is provided with a convex sawtooth-shaped rifle. As the rifle has a guiding and an accelerating functions, the sand removing efficiency can be improved, the power consumption of a pulp inlet pump can be reduced, and the paper pulp output quantity of a sand removing device and the purification efficiency can be improved.
Description
The utility model relates to the preceding pulp processing equipment of paper machine, particularly a kind of vertical device of removing paper pulp medium sand or slag by centrifugal force.
In the paper-making process, before entering paper machine, paper pulp all needs to remove sand or slag in the paper pulp.Existing desanding (slag) device is vertical circular cone desander, and its inwall is smooth surface, lacks guide effect, thus paper pulp or mix suspending fluid by the time resistance bigger, acceleration is less, desanding (slag) efficient is low, output is not high yet.
The purpose of this utility model is a kind of novel vertical centrifugal circular cone desander of design, improves the desanding efficiency of existing desander and the quantum of output of paper pulp.
The purpose of this utility model is by the cylinder inner surface at the circular cone desander rifling profile of tooth to be set to realize.
Accompanying drawing 1 is the structural representation of the utility model rifling circular cone desander, and Fig. 2 is the enlarged drawing of the zigzag rifling part of projection.1 for advancing to starch flange among the figure, and 2 is good slurry outlet(discharge) flange, and 3 for going out roof of mouth, and 4 is the upper body, and 5 is middle body, and 6 is lower body, and 7 is nut, and 8 are the mouth that shakes out.
Provide the embodiment of the utility model desander in conjunction with the accompanying drawings.
Rifling circular cone desander, it promptly advances to starch flange 1 by the pulp import part, paper pulp exit portion after desanding, promptly good slurry outlet(discharge) flange 2, go out roof of mouth 3, the desander working portion, promptly the upper body 4, middle body 5, lower body 6 and sand (slag) discharge section, promptly nut 7, and the mouth 8 that shakes out is formed, the paper pulp that send through pump pressure enters desander by the flange that advances to starch that links to each other with the paper pulp conveyance conduit, advance to starch flange 1 and place a side of upper body 4, its tube wall and upper body inner surface are tangent, upper body 4, middle body 5, lower body 6 is a conic tube, but split manufacturing, be formed by connecting, also can be monoblock type, directly make one, the inner surface of conic tube is made the zigzag rifling of projection as shown in Figure 2, the height of tooth is looked the size of desander and different, exit, the upper end top cover 3 of upper body and good slurry outlet(discharge) flange 2, and the mouth 8 that shakes out is installed by nut 7 in the lower end of lower body.Paper pulp or other suspension are sent into them with pump and are tangentially entered the desander conical section in the upper body and produce and to rotatablely move and centrifugal force, along with reducing of radius, fluid is quickened and is entered downwards among the zigzag of projection of rifling, advance downwards along spiral slide, the bigger impurity of proportion such as sand and slag is at middle body 3, thrown to the periphery of cone in the lower body 6, being close to wall moves downward, because of the increase of its centrifugal force much bigger than the planomural cone, promoted the centrifugation of impurity and good slurry, impurity is discharged from the nylon slag-drip opening, and the diameter of nylon mouth requires to decide according to paper pulp.What the utility model adopted is the zigzag of projection, and other shape profile of tooth also can play effect same, decides on the quantum of output and the character of paper pulp.
The utility model is made at conical wall and is used the rifling zigzag that firearms tube principle is made, the cone desander can be cylinder iron, various materials such as alloying metal or macromolecular material are made, paper pulp or other need the suspended material of centrifugal desanding (slag), and all available the method improves slagging-off efficient, also because of the guide effect to lower flow channel of rifling, reduced the slurry flow resistance, make the into power consumption decline of stock pump, desander output, purification efficiency all is improved.
Claims (3)
1, a kind of rifling circular cone desander, it is by pulp import part, paper pulp exit portion after desanding, impurity discharge sections such as desander working portion and sand are formed, and it is characterized in that on the inner surface of the conic tube of desander working portion the rifling profile of tooth being set.
2,, it is characterized in that on the inner surface of the lower body of desander or middle body and lower body, being provided with the zigzag rifling of projection according to the said rifling circular cone of claim 1 desander.
3, according to claim 1 or 2 said rifling circular cone desanders, it is characterized in that the rifling profile of tooth is a kind of zigzag of projection.
