Description
Technical field
The utility model belongs to stock cleaning equipment technical field in papermaking, is specifically related to a kind of scummer housing.
Background technology
Scummer is the equipment of the fine impurities in paper pulp of removing for papermaking work, and it is separated with impurity by the slurry in scummer housing by centrifugal motion, and therefore, in work, scummer enclosure interior is constantly subject to the friction of slurry.The scummer housing of prior art is welded by upper and lower casing docking, this welding combination has following shortcoming: 1, in work, thereby the impact of slurry makes upper and lower casing occur relatively to rock and produces shearing force, and shearing force concentrates on the articulamentum of junction, causes articulamentum to lose efficacy; While 2, welding, the junction of enclosure interior can produce overlap, is difficult for polishing, and hanging in causing using, can affect slagging-off effect during use; 3, easily cause welding process middle shell inside to there will be welding slag.
Utility model content
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of upper and lower casing to connect reliable scummer housing.
The technical solution of the utility model is achieved in that
A kind of scummer housing, comprise upper shell, lower house, be located at the pulp-inlet pipe on upper shell and be located at the screenings outlet on lower house, the cross section of upper shell is circular, lower house and upper shell junction far-end are directly less than junction end diameter, on the end face of upper shell, be also provided with good slurry outlet, in good slurry outlet, be provided with good slurry pipe, the central axis conllinear of the central axis of good slurry pipe and upper shell, good slurry pipe stretches into the inside of upper shell, pulp-inlet pipe is located on the curved surface of upper shell, in screenings outlet, is also provided with thread bush;
The lower end of upper shell is provided with upper casing port, and the upper end of lower house is provided with lower casing port, and upper casing port is connected with the inwall of lower house, between lower casing port and the outer wall of upper shell, is provided with articulamentum.
Preferably, articulamentum is weld layer.
Preferably, the vertical range between upper casing port and lower casing port is 8-12mm.
Preferably, the height of weld layer is 2.5-3.5mm.
Preferably, upper shell and lower house are the housing that steel plate rolls.
Compared with prior art, a kind of scummer housing the utility model proposes, the upper and lower casing of scummer connects for inserting bridging type, the lower surface of upper shell abuts against lower house inside, between lower casing port and the outer wall of upper shell, be provided with articulamentum, therefore lifting surface area is large, and articulamentum is stressed little, connects reliable; In when welding, because the lower surface of upper shell abuts against lower house inside, stop that welding fluid flows to enclosure interior and forms overlap, while avoiding work, there is hanging phenomenon, welding process middle shell inside there will not be welding slag simultaneously.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial view at A place in Fig. 1.
In figure: 1, upper shell; 11, upper casing port; 2, lower house; 21, lower casing port; 3, screenings outlet; 4, thread bush; 5, good slurry outlet; 6, good slurry pipe; 7, pulp-inlet pipe; 8, articulamentum.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1-2, a kind of scummer housing, comprise upper shell 1, lower house 2, be located at the pulp-inlet pipe 7 on upper shell 1 and be located at the screenings outlet 3 on lower house 2, the cross section of upper shell 1 is circular, lower house 1 is directly less than junction end diameter with upper shell 1 junction far-end, on the end face of upper shell 1, be also provided with good slurry outlet 5, in good slurry outlet 5, be provided with good slurry pipe 6, good slurry pipe 6 stretches into the inside of upper shell 1 and stretches under the slurry liquid level of upper shell 1 inside, its length designs according to the minimum level of the slurry of upper shell 1 inside in reality use, the central axis conllinear of the central axis of good slurry pipe 6 and upper shell 1, pulp-inlet pipe is located on the curved surface of upper shell 1, in screenings outlet 3, be also provided with thread bush 4, the lower end of upper shell 1 is provided with upper casing port one 1, the upper end of lower house 2 is provided with lower casing port 21, upper casing port one 1 is connected with the inwall of lower house 2, between the outer wall of lower casing port 21 and upper shell 1, be provided with articulamentum 8.
A kind of scummer housing the utility model proposes, during use, slurry flows into from pulp-inlet pipe 7, in scummer enclosure interior, along chamber wall, rotate, good slurry with fiber is gathered in center, and discharged by the good slurry pipe 6 of being located at upper shell 1 center, and screenings precipitation is discharged by the screenings outlet 3 of lower casing port 21, enter the ceramic mouth connecting for deslagging by thread bush 4 in screenings outlet 3, upper with prior art, the welding of lower house dock is different, scummer of the present utility model upper, lower house connects for inserting bridging type, the lower surface of upper shell 1 abuts against lower house 2 inside, bear the fricative shearing force of enclosure interior slurry, reduced the stressed of articulamentum 8, connect more reliable, insert bridging type connection simultaneously and there are two place's tie points, one place is the tie point at articulamentum 8 places, one place is the tie point that upper casing port one 1 contacts with lower house 2 inwalls, therefore stability is better, on, between lower house, being difficult for generation rocks relatively, the stability of scummer housing is better.
Another embodiment of the present utility model, as a preferred version, articulamentum 8 is weld layer, for guaranteeing connection reliability, the thickness of weld layer is 2.5-3.5mm, be welded to connect reliability high, weld layer is welded by argon arc welding, because the lower surface of upper shell abuts against lower house inside, during welding, prevent that welding slag from entering enclosure interior, and the welding point of welding is angle joint, avoid the overlap that in prior art, banjo fixing butt jointing welding produces, impact slagging-off effect, with reference to Fig. 2, layer is located between lower casing port 21 and upper shell 1 outer wall, because lower casing port 21 is compared with articulamentum 8 height, therefore articulamentum 8 is difficult for being worn, long service life.
Another embodiment of the present utility model, as a preferred version, as shown in Figure 1, upper shell 1 is cylindric, lower house 2 is cone-shaped.
