Rivet of the present invention position is with the blower wheel of anti-wear block, wherein the inner end of multiple described blades adopts wear resistance electrode repair welding to have more than one solder joint with the front end face of described wheel disc respectively, the quantity of blade is 6-18, and the quantity of described rivet is 3-10.
Rivet of the present invention position is with the blower wheel of anti-wear block, the interior ring radius size of wherein said each deep bead is 1.2-1.8 times of rivet radius size, the height of each deep bead is 20-30mm, the thickness of each deep bead is 6-10mm, the quantity of described blade is 8-16, and the quantity of described rivet is 4-8.
Rivet of the present invention position is with the blower wheel of anti-wear block, wherein the interior ring radius size of each described deep bead is 1.5 times of rivet radius size, the height of each deep bead is 25mm, the thickness of each deep bead is 8mm, the quantity of described blade is 12, and the quantity of described rivet is 6.
Rivet of the present invention position is with the blower wheel of anti-wear block, it comprises the circular wheel disc of the work of being rotated counterclockwise, the outside of wheel disc front end face is provided with multiple blades, the middle part of wheel disc is provided with multiple rivets that penetrate vertically wheel disc card, on wheel disc, be positioned at counter clockwise direction one side of each rivet respectively around being provided with semicircular deep bead, the center of each deep bead respectively with around the center of rivet coincide, the rear end of each deep bead adopts wear resistance electrode to be weldingly connected with the front end face of wheel disc respectively, the interior ring radius size of each deep bead is greater than the rivet cap portion radius size of rivet, each deep bead is greater than the height of the rivet cap portion of rivet along the height of fore-and-aft direction. in use, because each deep bead is weldingly fixed on each rivet periphery, can stop sandstone in return, the infringement of coal dust granule to rivet, use wear resistance electrode to carry out soldering reinforcing to rivet and blade simultaneously, increase anti-wear performance. prove through many experiments, the wearing and tearing to rivet and blade, with the blower wheel of anti-wear block, can effectively be reduced in drum of the present invention rivet of the present invention position, greatly extend the service life of blower wheel, reduce accident rate. therefore, rivet of the present invention position has long service life with the blower wheel of anti-wear block, wear-resistant, can reduce the feature of maintenance of equipment cost.
Below in conjunction with accompanying drawing, rivet of the present invention position is described in further detail with the blower wheel of anti-wear block.
Brief description of the drawings
Fig. 1 is the front view of rivet of the present invention position with the structural representation of the blower wheel of anti-wear block.
Detailed description of the invention
As shown in Figure 1, rivet of the present invention position is with the blower wheel of anti-wear block, comprise the circular wheel disc 1 of the work of being rotated counterclockwise, the outside of wheel disc 1 front end face is provided with multiple blades 2, the middle part of wheel disc 1 is provided with multiple rivets 3 that penetrate vertically wheel disc 1 card, on wheel disc 1, be positioned at counter clockwise direction one side of each rivet 3 respectively around being provided with semicircular deep bead 4, the center of each deep bead 4 respectively with around the center of rivet 3 coincide, the rear end of each deep bead 4 adopts wear resistance electrode to be weldingly connected with the front end face of wheel disc 1 respectively, the interior ring radius size of each deep bead 4 is greater than the rivet cap portion radius size of rivet 3, each deep bead 4 is greater than the height of the rivet cap portion of rivet 3 along the height of fore-and-aft direction.
As a further improvement on the present invention, the inner end of above-mentioned multiple blades 2 adopts wear resistance electrode repair welding to have more than one solder joint with the front end face of wheel disc 1 respectively, and the quantity of blade 2 is 6-18, and the quantity of rivet 3 is 3-10.
