Detailed Description
The invention is further described with reference to the following figures and detailed description.
As shown in fig. 1 to 5, the invention relates to a material cleaning device for a cylinder of a sintering mixer, which comprises a roller body 1, a lug 2 and a connecting piece 3; the plurality of the protruding thorns 2 are arranged, and the plurality of the protruding thorns 2 are distributed on the peripheral rolling surface of the roller body 1 at intervals; the two ends of the roller body 1 are respectively provided with the connecting piece 3, one end of the connecting piece 3 is connected with the end part of the roller body 1, and the other end of the connecting piece 3 is a free end.
When the cleaning device provided by the invention is used for cleaning the sintering mixer cylinder 5, the roller body 1 is only required to be placed in the sintering mixer cylinder 5, and then the roller body 1 is rolled relatively in the sintering mixer cylinder 5 to realize the scattering and cleaning of the bonding materials through the corresponding burs 2.
The protruding spines 2 are used for puncturing and scattering bonding materials on the inner wall of the cylinder 5 of the sintering mixer under the impact action of the protruding spines 2 in the cleaning process, and further the purpose of cleaning the materials is achieved. In order to realize the purpose, the outer end of the protruding thorn 2 can be provided with a structure with a better puncturing effect so as to be conveniently and smoothly punctured into the bonding material layer; considering that the burs 2 need to bear certain gravity of the roller body 1 and the burs 2 can collide with the inner wall of the cylinder 5 of the sintering mixer during the tumbling process of the roller body 1, the burs 2 need to have certain structural strength. Specifically, referring to the drawings, the invention can be provided with the burs 2 in a plate-shaped structure; and more specifically, the direction of the outer edge of the spine 2 of the plate-shaped structure is further consistent with the rolling direction of the roller body 1; thus, the outer edge of the bur 2 has better puncturing effect and the effect of preventing the bur 2 from deforming in the process of rolling along with the roller body 1. Of course, the plate thickness of the corresponding bur 2 can be reasonably set according to the actual situation; the thinner the plate thickness of the protruding spine 2 is, the better the puncturing effect corresponding to the outer edge of the protruding spine 2 is, but the structural strength of the protruding spine 2 is relatively poorer; conversely, the thicker the thickness of the spinous processes 2, the poorer the puncture effect of the outer edge of the corresponding spinous process 2, but the greater the structural strength of the spinous process 2.
Without loss of generality, the stabs 2 are mainly used for stabbing into the bonded material layer so as to stab and break the bonded material; therefore, the depth of the spurs 2, namely the depth of the spurs 2 penetrating into the bonding material can be reasonably set according to the layer thickness of the bonding material; in general, it is preferable to set the depth of the spinous processes 2 to 20cm to 60 cm; for example, the depth of the spinous processes 2 is set to 50 cm.
In addition, the connecting member 3 of the present invention is used to connect with both ends of the drum body 1, so as to realize indirect control of the drum body 1 through the connecting member 3. For example, by means of the connecting element 3, to push and pull the roller body 1 in the axial direction, and thus to adjust the axial movement of the roller body 1 in the cylinder 5 of the sinter mixer; and by oscillating the coupling 3 reciprocally, the aim of actively tumbling the cylinder 1 inside the barrel 5 of the sinter mixer is achieved.
More specifically, the connecting piece 3 can be a steel wire rope; and in order to ensure the structural strength of the wire rope, a wire rope having a diameter of about 20mm may be used. In addition, when the steel wire rope is used as the connecting piece 3, a protective layer can be further wrapped on the steel wire rope; such as coating with anticorrosive paint or rubber material.
More specifically, the connecting member 3 of the present invention, which is rotatably coupled to the end of the drum body 1, allows the drum body 1 to be tumbled with respect to the connecting member 3, thereby preventing the connecting member 3 from being entangled with itself during tumbling of the drum body 1. More specifically, in order to ensure the tumbling of the drum body 1 with respect to the connecting member 3, it is generally preferable to set the connecting point of the connecting member 3 with the end of the drum body 1 to the center of the end of the drum body 1; reference may be made in detail to the connection locations illustrated in the accompanying drawings.
In addition, in the present invention, the roller body 1 is preferably provided in a cylindrical shape, and the inside thereof is a hollow structure, that is, the inside of the roller body 1 is a cylindrical cavity structure. In this case, in order to improve the structural strength of the drum body 1, a stay 4 is further provided in the cylindrical cavity in the present invention, as shown in fig. 4. Wherein, the stay bars 4 are provided with a plurality of stay bars 4, and the stay bars 4 are staggered along the axial direction of the roller body 1 at intervals. The staggered arrangement means that the length directions of two adjacent support rods 4 are in a crossed relationship, so that the supporting effect on the roller body 1 can be realized in multiple directions, and the overall structural strength of the roller body 1 is finally improved.
Of course, the roller body 1 of the present invention should have a certain weight, so as to ensure that it can have a good penetrating effect on the adhesive material layer by its own gravity during the rolling process. Generally, the roller body 1 can be made by rolling a steel pipe or a steel plate, and sealing plates are arranged at two ends of the roller body for plugging; in order to improve the weight and structural strength, the wall thickness of the drum body 1 may be set relatively thick; and the structural strength and the balance weight can be further improved by arranging the corresponding stay bars 4. Of course, if necessary, a counterweight structure may be further provided in the drum body 1 to perform counterweight.
FIG. 5 is a schematic structural diagram of the material cleaning device of the present invention when it is placed in the barrel 5 of the sintering mixer to be cleaned; meanwhile, driving mechanisms 6 are respectively arranged at two ends of the cylinder 5 of the sintering mixer, so that the driving mechanisms 6 can be used for realizing the axial position adjustment of the roller body 1 and controlling the rolling of the roller body 1 through corresponding connecting pieces 3.
Specifically, the invention further provides a cleaning method for a cylinder of a sintering mixer, which adopts the cleaning device for the cylinder of the sintering mixer, and simultaneously, the roller body 1 is placed in the cylinder 5 of the sintering mixer; in order to ensure the effective rolling of the roller body 1 in the cylinder 5 of the sintering mixer, the diameter of the roller body 1 is usually set to be 0.2-0.6 times of the diameter of the cylinder of the sintering mixer, and after the burs 2 are added, the peripheral outline size of the burs 2 should also be smaller than the diameter of the cylinder of the sintering mixer, and the peripheral outline size needs to be smaller than the diameter corresponding to a material layer after the cylinder of the sintering mixer needing to be cleaned is communicated with the material layer adhered to the cylinder of the sintering mixer, so as to ensure that the whole roller body can be effectively put in. In addition, the length of the roller body 1 is preferably 0.2 to 0.5 times of the length of the cylinder of the sintering mixer, and accordingly the roller body 1 can be pulled by the connecting pieces 3 at the two ends so as to axially move in the cylinder 5 of the sintering mixer, so that the cleaning of the inner wall of the whole cylinder 5 of the sintering mixer is realized; by providing the relatively short roller body 1, the material cost can be saved while reducing the size and weight of the roller body 1 to facilitate the carrying movement. Of course, without loss of generality, when the roller body 1 is placed into the barrel 5 of the sintering mixer, the free ends of the connecting pieces 3 thereof, which are located at both ends of the roller body 1, should respectively penetrate out of both ends of the barrel 5 of the sintering mixer; so as to control the roller body 1 through the respective free ends.
After the roller body 1 is arranged, the material cleaning treatment of the adhesive material layer can be realized only by controlling the relative rolling and the relative axial movement of the roller body 1 in the cylinder 5 of the sintering mixer. Specifically, the relative rolling of the drum body 1 and the barrel 5 of the sintering mixer may be effected by driving the barrel 5 of the sintering mixer to rotate by itself, by actively driving the tumbling of the drum body 1, or by driving both the barrel 5 of the sintering mixer and the drum body 1. Of course, without loss of generality, in order to realize the active tumbling of the driving roller body 1, referring to fig. 5, the present invention further provides driving mechanisms 6 respectively arranged outside the two ends of the cylinder 5 of the sintering mixer, and the free ends of the connecting pieces 3 at the two ends of the roller body 1 respectively penetrate through the two ends of the cylinder 5 of the sintering mixer and then are connected with the driving mechanisms 6 at the corresponding sides. In this way, the drive of the drum body 1 can be achieved by means of the corresponding drive mechanism 6. Of course, the driving of the drum body 1 by the driving mechanism 6 can realize the driving of the axial movement of the drum body 1 in the cylinder 5 of the sintering mixer in addition to the tumbling driving of the drum body 1.
