Therefore, in order to address the above problem, the purpose of this utility model is to provide a kind of rotary kiln circle scavenge unit, and described rotary kiln circle scavenge unit can remove or stop kiln circle to form effectively, and can not cause damage to kiln lining.In addition, described rotary kiln circle scavenge unit also has easy to make, simple operation and other advantages.
According to exemplary embodiment of the present utility model, a kind of rotary kiln circle scavenge unit is provided, it comprises: steel pipe; Harrow nail, is arranged on the head of steel pipe, and distributes radially around the outer peripheral face of steel pipe.
Preferably, be furnished with many row's harrow nails at the outer peripheral face of steel pipe, each row's harrow nail is all along the axially-aligned of steel pipe.
According to exemplary embodiment of the present utility model, same row's harrow nail interval each other can be 10cm.
According to exemplary embodiment of the present utility model, adjacent row's harrow nail can stagger each other and arrange.
According to other embodiment of the present utility model, the afterbody of steel pipe can be provided with handle.
According to other embodiment of the present utility model, the afterbody of steel pipe can be provided with drive unit.
On the kiln head cover of rotary kiln, open a peep hole, make the size of peep hole allow freely the come in and go out cylindrical shell of rotary kiln of rotary kiln circle scavenge unit, the head of the steel pipe with harrow nail is extend into kiln circle formation district, utilize moving around of kinetic energy that cylindrical shell when rotation of rotary kiln produces and relative displacement and rotary kiln circle scavenge unit, effectively remove kiln circle or stop kiln circle to form.
Therefore, adopt described rotary kiln circle scavenge unit can effectively remove kiln circle or stop kiln circle to form, and can not cause damage to kiln lining.In addition, described rotary kiln circle scavenge unit also has easy to make, simple operation and other advantages.
Brief description of the drawings
Fig. 1 illustrates the rotary kiln circle scavenge unit according to the utility model exemplary embodiment.
Fig. 2 is the cutaway view intercepting along the I-I line in Fig. 1.
Detailed description of the invention
Now with reference to accompanying drawing, embodiment of the present utility model is more fully described, exemplary embodiment of the present utility model shown in the drawings.
Fig. 1 illustrates the rotary kiln circle scavenge unit according to the utility model exemplary embodiment, and Fig. 2 is the cutaway view intercepting along the I-I line in Fig. 1.
As shown in Figures 1 and 2, comprise according to the rotary kiln circle scavenge unit of exemplary embodiment of the present utility model: steel pipe 3, has certain length; Harrow nail 7, is arranged on the head of steel pipe 3, and distributes radially around the outer peripheral face of steel pipe 3.Along axially seeing of steel pipe 3, harrow nail 7 is arranged to many rows, and the setting of harrow nail 7 each intervals in same row, and every row's harrow nail 7 staggers each other and arranges with adjacent row's harrow nail 7.In this exemplary embodiment, same row's the about 10cm of harrow nail each interval, but the utility model is not limited to this.In addition, the harrow nail that it should be noted that same row interval is each other not the smaller the better, when harrow nail 7 arranges, to remove effect when overstocked undesirable on the contrary, and certainly, harrow nail 7 arranged that while dredging, to remove effect also undesirable, therefore, harrow nail 7 should not arrange overstocked or excessively thin.
In addition, from Fig. 1 and Fig. 2, can find out, harrow nail 7 can be set to cube shaped.But the utility model is not limited to this, harrow nail 7 also can be the shape such as screw, nail and other various rules that can be used for striking off kiln circle or irregularly shaped.
Preferably, steel pipe 3 and harrow nail 7 can be made up of exotic material.Harrow nail 7 can be fixed on steel pipe 3 by the method for welding, but the utility model is not limited to this.
According to other embodiment of the present utility model, the afterbody of steel pipe 3 can be provided with handle, is convenient to staff and holds described rotary kiln circle scavenge unit, and meanwhile, handle can also protect staff to avoid the danger of high-temperature operation; Do not having in handled situation, staff puts on high-temperature-resistant glove and holds the afterbody of steel pipe 3 and also can remove operation.
According to other embodiment of the present utility model, the afterbody of steel pipe 3 also can arrange drive unit, both can save labour, can also improve operating efficiency.
On the kiln head cover 4 of rotary kiln, open a peep hole 5, make the size of peep hole 5 allow can freely the come in and go out cylindrical shell 2 of rotary kiln of described rotary kiln circle scavenge unit.In the time removing the work of kiln circle, staff can extend into cylindrical shell 2 inside by the head of the steel pipe 3 with harrow nail 7, and makes harrow nail 7 contact Yao Quan district 6, and the afterbody of steel pipe 3 is placed on the outside of cylindrical shell 2.Cylindrical shell 2 produces kinetic energy while rotation, utilizes the relative motion between described rotary kiln circle scavenge unit and cylindrical shell 2, just can realize along the radial direction of cylindrical shell 2 and remove kiln circle; In addition, staff manually or utilize drive unit to apply power to described rotary kiln circle scavenge unit, makes rotary kiln circle scavenge unit along axially the moving around of cylindrical shell 2, to realize the axial removing kiln circle along cylindrical shell 2.Therefore, adopt described rotary kiln circle scavenge unit can be respectively along radial and axial effective removing kiln circle of the cylindrical shell 2 of rotary kiln or stop kiln circle to form.
In addition, harrow nail of the present utility model is arranged on the outer peripheral face of steel pipe radially, therefore the active force between each harrow nail and kiln circle is smaller, and the harrow nail of in a row arranging is only to being formed on cylinder inboard wall and having scavenging action significantly and can not damage inwall and the kiln lining of cylindrical shell from the outstanding kiln circle of cylinder inboard wall, staff can also observe removing situation by peep hole simultaneously, originally remove and just can stop removing operation when complete when observing kiln cycle basis, therefore, while adopting rotary kiln circle scavenge unit of the present utility model to carry out prune job, can not cause damage to kiln lining.In addition, in the time adopting described rotary kiln circle scavenge unit to remove operation, needn't reduce charging or stop charging, the in the situation that of the normal work of rotary kiln, just can carry out the removing of kiln circle at any time and can not affect production, being conducive to enhance productivity.
In addition, the rotary kiln just having formed for kiln circle or also do not form the rotary kiln of kiln circle, remove operation if adopt rotary kiln circle scavenge unit of the present utility model, the kinetic energy that only utilizes the cylindrical shell rotation of rotary kiln to produce, by the relative motion between described rotary kiln circle scavenge unit and cylindrical shell, just can effectively remove kiln circle or stop kiln circle to form.
Therefore, adopt described rotary kiln circle scavenge unit not only can realize the radial and axial of cylindrical shell along rotary kiln respectively and effectively remove kiln circle or stop kiln circle to form, and can not cause damage to kiln lining.In addition, described rotary kiln circle scavenge unit also has easy to make, simple operation and other advantages.
Although specifically illustrate and described the utility model with reference to exemplary embodiment of the present utility model, but it should be understood by one skilled in the art that, in the case of not departing from the spirit and scope of the present utility model that are defined by the claims, can carry out to it various changes of form and details.
