Summary of the invention
The technical problems to be solved in the utility model has provided a kind of comb crack structure that is used for the grate plate of ball mill partition panel.
For solving the problems of the technologies described above,, provide a kind of ball mill grate plate according to the technical solution of the utility model, which is provided with a plurality of comb seams, each sewer of combing has entrance side and the outlet side that enters and discharge for material, it is characterized in that, each seam of combing is the horn mouth shape of arc.
In above-mentioned grate plate, the cross section of horn mouth shape on width of this arc comprises entrance, outlet leading portion and outlet back segment.
In above-mentioned grate plate, the cross section of this entrance is trapezoidal.
In above-mentioned grate plate, this trapezoidal base is positioned at this entrance side.
In above-mentioned grate plate, the side in the cross section of this outlet leading portion is a straight line.
In above-mentioned grate plate, the side in the cross section of this outlet back segment is the camber line that protrudes to center line of discharge.
In above-mentioned grate plate, the camber line side in the cross section of the straight line side in the cross section of this outlet leading portion and this outlet back segment is tangent.
According to grate plate of the present utility model, the seam of in use combing is not easy to block abrasive body and material, and the material that the arc design makes ball be easy to block in motion process cleans out, stronger automatically cleaning ability is arranged, avoided the obstruction of combing and stitching, improved grinding efficiency, avoided stopping up the stopping production accident that causes, thereby improved the output and the Grinding Quality of ball mill because of serious.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 2 a and Fig. 2 b have been respectively out according to the front view of the grate plate of the utility model first embodiment and the cutaway view done along the radial symmetric line of this grate plate; The cutaway view of Fig. 3 for being done along the A-A line among Fig. 2 a wherein shows the section that contains the seam of combing; Fig. 4 is the schematic diagram of the grate plate of the utility model second embodiment.
Shown in Fig. 2 a, this grate plate 1 is a fan shape, and it has the comb seam 2 for the material turnover.
As Fig. 2 a and shown in Figure 3, this comb seam 2 has entrance side 4 and the outlet side 3 that enters and discharge for material, and the cross section that this comb is sewn on the width (vertical with the direction of vertical line of symmetry 9 of the seam of combing) comprises entrance 7, outlet leading portion 6 and outlet back segment 5.This cross section is along short transverse line of symmetry 10 symmetries of the seam of combing.The cross section of entrance 7 is trapezoidal, and this trapezoidal base is positioned at entrance side 4; The side in the cross section of outlet leading portion 6 is a straight line, and the side in the cross section of outlet back segment 5 is the camber line that protrudes to center line of discharge, and the camber line side in the cross section of the straight line side in the cross section of outlet leading portion 6 and outlet back segment 5 is tangent.
This cross section is along the vertical line of symmetry 9 of seam of combing, the direction extension parallel with this vertical line of symmetry 9 and be formed on the grate plate 2.Form the comb seam of arc horn mouth shape of the present utility model thus.
As shown in Figure 4, the comb of the grate plate of second embodiment seam is arranged along the radial symmetric line 8 perpendicular to grate plate.At this moment, the comb of first embodiment seam is revolved turn 90 degrees and on grate plate, to form the comb vertical and stitch with the radial symmetric line 8 of grate plate.At this, the comb crack structure of second embodiment is identical with the comb crack structure of first embodiment, omits its detailed description at this.
Because it is the horn mouth design of arc that the comb of the utility model ball grate plate seam adopts section, so in use be not easy to block abrasive body and material, and the material that the arc design makes ball be easy to block in motion process cleans out, stronger automatically cleaning ability is arranged, avoided the obstruction of combing and stitching, improved grinding efficiency, avoided having very high practical value because of the serious stopping production accident that causes of stopping up.
