Fig. 1 is the overall structure schematic diagram of pressure sieve rotor in the utility model;
Fig. 2 is the deployed configuration schematic diagram of cylinder sleeve in Fig. 1;
Fig. 3 is the structural representation of bubbling in Fig. 1.
The name that in figure, each Reference numeral is corresponding is called: 10-axle sleeve, 20-conic tube, 30-cylinder, 31-cylinder body, 32-cylinder sleeve, 33-sleeve blank, 34-bubbling.
Detailed description of the invention
In the utility model, an embodiment of pressure sieve rotor is as shown in Fig. 1 ~ Fig. 3, for the pulp pressure screening installation in paper industry, comprise the axle sleeve 10, conic tube 20 and the cylinder 30 that set gradually from top to bottom along axis, three is welded and fixed connection successively.
The structure of axle sleeve 10 is same as the prior art, is weldingly fixed on the little end opening of conic tube 20.Conic tube 20 is end enclosure structure, first corresponding sheet material is forged into spherical crown shape during manufacture, then the part of sheet material corresponding to described spherical crown shape top is removed, the conic tube 20 that final formation upper end is little end opening, lower end is large end opening.The part that described ball coronal structure is corresponding with the barrel of conic tube 20 can forge into according to the structural requirement of conic tube 20 curved form that bus is straight line, the sphere form of also can be bus be curve.Adopt above-mentioned end enclosure structure, compared with the conic tube 20 of volume circle butt welding process manufacture, need not weld, the imbalance avoiding welding stress deformation and cause thus, symmetrical configuration, uniform wall thickness, dynamic balance performance are good, effectively can reduce the paste block amount of rotor, and can use manpower and material resources sparingly, improve product quality and realize higher rotating speed.
Cylinder 30 is weldingly fixed on the large end opening of conic tube 20, comprises the cylinder body 31 of drum and is set in the cylinder sleeve 32 of cylinder body 31 outside.Wherein cylinder sleeve 32 is shaped by corresponding sleeve blank 33 volume circle, the internal face of cylinder sleeve 32 and the outside wall surface shape of cylinder body 31 are coincide, two wall close fit during assembling, cylinder sleeve 32 can rely on cylinder body 31 to realize stable location, meet the strict demand of cylinder 30 pairs of outside dimensions, ensure the gap between cylinder 30 and the screen cylinder outside it, and then ensure screening effect.Sleeve blank 33 overall Sheet Metal Forming Technology that adopts before volume circle is shaped bubbling 34, and the shape of bubbling 34 is hemispherical, and for the formation of rotor, this sleeve blank 33 forms bubbling plate.Rotor adopts aforesaid way shaping, can avoid single processing rotor in prior art, locating and machining hole, assemble and weld the problem that the technique caused is loaded down with trivial details, poor, the difficult quality of processing uniformity controls, mismachining tolerance is large one by one, while, can cut down finished cost and power consumption of polymer processing greatly.Further, by rationally arranging bubbling 34 shape, can operationally produce reliable and stable recurrent pulses, the turbulence effects of slurry is improved, effectively reduce equipment energy consumption, improve the rotating speed of rotor, reach the effect of high yield and saving energy.
Sleeve blank 33 there is bubbling 34 due to stamping, easily there is irregular deformation in the opening's edge of volume bowlder bubbling 34 concave side and form polygonized structure, in order to avoid affecting fitting tightly of cylinder sleeve 32 and cylinder body 31 thus, cylinder sleeve 32 also needs to use mould by level and smooth for the opening's edge punching press of bubbling 34 concave side after punching press forms bubbling 34, volume circle, coplanar with the internal face of the opening's edge and cylinder sleeve 32 that make bubbling 34 concave side, ensure the outside dimension of cylinder sleeve 32.
During assembling, axial two ends both cylinder sleeve 32 relies on cylinder body 31 are welded by section and are realized fixing, if there are wearing and tearing in the rotor of in use cylinder sleeve 32 or bubbling 34 formation on it, easily the multistage interval weld seam that section weldering is formed can be removed, thus cylinder sleeve 32 is removed to repair rotor, the maintenance time of pressurized screen equipment can be greatly reduced, cylinder body 31 can reuse, and effectively improves the utilization rate of material and saves manufacturing cost.
In the utility model, an a kind of embodiment of pressurized screen comprises screen cylinder, coaxially arranges with screen cylinder and rotate the pressure sieve rotor be assemblied in screen cylinder, the structure of screen cylinder is same as the prior art, pressure sieve rotor in pressure sieve rotor and above-described embodiment, no longer describes in detail herein.
In the above-described embodiments, rotor is that the bubbling 34 be stamped to form by the barrel of described cylinder sleeve 32 is formed, and the shape of bubbling 34 is hemispherical, and cylinder sleeve 32 and cylinder body 31 adopt section to be welded and fixed.In other embodiments of the present utility model, rotor also can replace with other forms, such as, adopt the projection form be fixed on cylinder sleeve 32 outer peripheral face, and for forming the bubbling of rotor,, the shape of 34 also can be arranged to other rotor shapes of the prior art as required.Cylinder sleeve 32 and cylinder body 31 also can adopt other modes to be fixed in addition, such as, on cylinder sleeve 32, arrange counter sink, cylinder body 31 arranges screwed hole, use sunk screw that both are removable fixing.
