Abstract
The utility model discloses a flow guide device of a superfine powder classifier, comprising a plurality of vertical type guide blades and V-shaped guide blades, wherein the vertical type guide blades are evenly distributed between the upper side of a top circumference of a coarse powder collection cone of the superfine powder classifier and the lower side of a middle shell body of a powder separating chamber; and one side of each V-shaped guide blade is fixedly connected with the outer side of the corresponding vertical type guide blade. The flow guide device not only can play a role in changing the direction and homogenizing the flow, but also can enable the concentration of passing powder-containing gas to be decreased.
Description
Technical field
The utility model relates to a kind of superfine powder grader, particularly a kind of superfine powder grader guiding device.
Background technology
Existing a kind of superfine powder grader contains separating chamber, middle meal collection cone, guiding device and cage rotor.Guiding device contains several vertical guide vanes; Vertical guide vane is distributed between middle meal collection cone top and the separating chamber central enclosure below; Vertical guide vane upper end is arranged on separating chamber's central enclosure; On the meal collection cone top circumference, cage rotor was positioned at the space that several vertical guide vanes of guiding device are surrounded during the lower end of vertical guide vane was arranged on.The main effect of guiding device is pulverized coal borne air flow is changed the flow direction through vertical guide vane, and even entering to supply the cage rotor in it to select powder by in the space that vertical guide vane surrounded from the gap between the vertical guide vane.Because the vertical guide vane of guiding device is rectangular plate, only can play break-in and current-sharing effect, and can not make the powder gas that contains that passes through reduce concentration.
The utility model content
The technical problem that the utility model will solve provides a kind of superfine powder grader guiding device, and this guiding device not only can play break-in and current-sharing effect, and can make the powder gas that contains that passes through reduce concentration.
For solving the problems of the technologies described above; A kind of superfine powder grader of the utility model guiding device; Contain several vertical guide vanes; Vertical guide vane also contains the V-arrangement guide vane between being distributed in the superfine powder grader below meal collection cone top circumference top and the separating chamber central enclosure, and a side of this V-arrangement guide vane and the outside of said vertical guide vane are fixedly linked.
The angle of said V-arrangement guide vane is 30 °-50 °, and the outside of said V-arrangement guide vane one side and the said vertical guide vane angle that is constituted that is fixedly linked is 120 °-150 °.
Also contain upper fixed seat and lower fixed seat; Upper fixed seat is made up of upper junction plate and bolt; One side of upper junction plate is arranged on the bottom of bolt, and lower fixed seat is made up of lower connecting plate and bearing pin, one side on the top that is arranged on bearing pin of lower connecting plate; The bolt of upper fixed seat is arranged on the said separating chamber central enclosure through locking nut; In the pin shaft hole that meal collection cone top circumference was provided with during the bearing pin of lower fixed seat was installed on, the upper and lower of said vertical guide vane is arranged on upper fixed seat and the lower fixed seat through bolt respectively, and vertical guide vane can be regulated direction through upper fixed seat and lower fixed seat.
The material of said vertical guide vane and V-arrangement guide vane is a wear-resisting steel plate, and interior subsides wear-resistant ceramic.
In the above-mentioned superfine powder grader guiding device; Because the vertical guide vane between being distributed on below the top of meal collection cone top circumference in the superfine powder grader and the separating chamber central enclosure; Each vertical guide vane the outside all be fixedly linked with V-arrangement guide vane one side, therefore can play break-in and current-sharing effect to the pulverized coal borne air flow that passes through; Simultaneously because pulverized coal borne air flow at first passes through vertical guide vane through the V-arrangement guide vane again; When pulverized coal borne air flow passes through the V-shaped part of V-arrangement guide vane; Pulverized coal borne air flow produces eddy current between V-shaped part and vertical guide vane; Dust and vertical guide vane surface and V-arrangement guide vane inner surface in the pulverized coal borne air flow hit to be bumped; Lose kinetic energy vertical guide vane surface, edge and V-arrangement guide vane inner surface after the collision and slide, thereby the powder gas concentration that contains that gets into the guiding device inner space is reduced greatly, so the powder separative efficiency is improved; Because pulverized coal borne air flow after producing eddy current between V-shaped part and the vertical guide vane, gets into the guiding device inner space along vertical guide vane surface again, therefore prior art has increased the powder-separating area territory relatively, thereby helps improving separative efficiency in addition.

The specific embodiment
Among Fig. 1, a kind of superfine powder grader guiding device contains several vertical guide vanes 1.Between vertical guide vane 1 is distributed in the superfine powder grader below meal collection cone top circumference top and the separating chamber central enclosure.Above-mentioned guiding device also contains V-arrangement guide vane 4, and as shown in Figures 2 and 3, a side 3 of this V-arrangement guide vane 4 is fixedly linked with the outside of said vertical guide vane 1.The angle of said V-arrangement guide vane 4 is 30 °-50 °; The outside of said V-arrangement guide vane 4 one sides 3 and said vertical guide vane 1 angle that is constituted that is fixedly linked is 120 °-150 °; Be this one side that the outside of vertical guide vane 1 links to each other with V-arrangement guide vane 4 one sides, the angle that is become with vertical guide vane 1 is 120 °-150 °.For strengthening abrasiveness, increasing the service life, the material of said vertical guide vane 1 and V-arrangement guide vane 4 is a wear-resisting steel plate, and interior subsides wear-resistant ceramic.Above-mentioned guiding device also contains upper fixed seat and lower fixed seat, and like Fig. 4 and shown in Figure 5, upper fixed seat is made up of upper junction plate 5 and bolt 6, one side on the bottom that is arranged on bolt 6 of upper junction plate 5.Like Fig. 6 and shown in Figure 7, lower fixed seat is made up of lower connecting plate 7 and bearing pin 8, one side on the top that is arranged on bearing pin 8 of lower connecting plate 7.The bolt 6 of upper fixed seat is arranged on the said separating chamber central enclosure through locking nut, in the pin shaft hole that meal collection cone top circumference was provided with during the bearing pin 8 of lower fixed seat was installed on.The upper and lower of said vertical guide vane 1 is arranged on upper fixed seat and the lower fixed seat through bolt respectively; Vertical guide vane 1 can be regulated direction through upper fixed seat and lower fixed seat; So just can adjust the direction of vertical guide vane 1 according to the classification powder, to reach optimum grading effect.During work; Pulverized coal borne air flow at first passes through vertical guide vane 1 through V-arrangement guide vane 4 again; When pulverized coal borne air flow passes through the V-shaped part 2 of V-arrangement guide vane 4; Pulverized coal borne air flow produces eddy current between V-shaped part 2 and vertical guide vane 1, dust and vertical guide vane 1 surface and V-arrangement guide vane 4 inner surfaces in the pulverized coal borne air flow are hit bump, lose after the collision kinetic energy along vertical guide vane 1 surface and V-arrangement guide vane 4 inner surfaces slide; Thereby the powder gas concentration that contains that gets into the guiding device inner space is reduced greatly, so the powder separative efficiency is improved; Because pulverized coal borne air flow after producing eddy current between V-shaped part 2 and the vertical guide vane 1, gets into the guiding device inner space along vertical guide vane 1 surface again, therefore prior art has increased the powder-separating area territory relatively, thereby helps improving separative efficiency in addition.
