Description

Technical Field

[0001] The utility model belongs to the technical field of anti-sticking of rolling barrels, and more specifically relates to an anti-sticking device for a mixing barrel of a sintering machine and the mixing barrel of the sintering machine. Background Art

[0002] With the continuous innovation and progress of industrial technology, the precision, efficiency and low energy consumption of industrial equipment operation have become an effective means for enterprises to reduce costs and increase efficiency. Therefore, it is particularly important for industrial enterprises to solve the links that restrict the above problems in daily production.

[0003] The mixing drum is the main production line equipment of the sintering machine. The mixing drum is responsible for mixing and pelletizing materials in the production process. The effect of mixing and pelletizing will directly affect the entire sintering process. At present, the lining material embedded in most mixing drums is nylon lining or ceramic lining. Its purpose is to drive the material to roll fully on the lining surface through the friction force on the lining surface, so that various materials can be fully mixed and pelletized in this process.

[0004] Since the mixing barrel needs to complete the work of granulation and balling, its inner wall surface cannot be too smooth. During operation, it is inevitable that sticky materials will form on its inner wall surface. This is an inevitable situation. Through observation and analysis of the formation of sticky materials, the sticky material thickness formed at the rolling ring of the barrel and the material drop point is the largest. The sticky materials at these two positions form a continuous large sticky material ring in the barrel. The sticky material thickness at the largest ring can reach about 800mm to 1000mm.

[0005] The cylinder of the mixing cylinder is rolled from steel plates, and the roller ring is forged separately. The forging thickness of the roller ring position is 5 to 10 times the thickness of the cylinder wall in other parts. The roller ring position is one of the most serious parts of sticking materials. The reason is that during the operation of the cylinder, the thinner rolled parts of the cylinder will be slightly deformed. Under the action of the material's own gravity and the cylinder's micro-deformation extrusion force, the mutual adhesion between the materials is destroyed, and the materials eventually fall off by themselves. At the roller ring position, due to the thicker cylinder wall, small micro-deformation, and relatively small deformation extrusion force, the material will be adhered at this position and continue to increase in height and thickness. The drop point of the material at the cylinder inlet is also one of the most serious parts of sticking materials. The reason is that when the material falls into the mixing cylinder, due to the humidity and viscosity of the material itself, under the action of the material inertia impact force, the adhesion between the materials is strengthened, resulting in a relatively thick material adhesion thickness here.

[0024] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0025] like Figure 1 As shown, the utility model provides an anti-sticking device for a mixing barrel of a sintering machine, comprising:

[0026] The first lining plate 1 and the second lining plate 2, the first lining plate 1 is used to connect with the inner wall of the mixing barrel, the second lining plate 2 is arranged on the side of the first lining plate 1 close to the center of the barrel, and an elastic component is arranged between the second lining plate 2 and the first lining plate 1, and the side of the first lining plate 1 close to the center of the mixing barrel and the two sides of the second lining plate 2 are provided with a sliding plate 4.

[0027] Specifically, in order to solve the problem in the prior art that the material in some positions in the sintering machine rolling barrel 3 is too thick and affects the normal production; the anti-sticking device for the sintering machine mixing barrel provided by the utility model comprises a first lining plate 1 and a second lining plate 2 arranged on the inner wall of the mixing barrel, and the first lining plate 1 and the second lining plate 2 are connected by an elastic component. As the rolling barrel 3 runs, the second lining plate 2 will vibrate slightly during the operation, so that this part will not have a large thickness of sticking material phenomenon, which can prevent the material from sticking into a ring shape and prevent the material from sticking more and more seriously. In addition, the setting of the increasing sliding plate 4 makes the surface of the first lining plate 1 and the second lining plate 2 contacting the material smoother, so that the anti-sticking device for the sintering machine mixing barrel itself is not easy to stick to the material.

[0028] Optionally, the reinforcing plate 4 includes a plurality of ceramic sheets.

[0029] Specifically, the increasing slide plate 4 is made of ceramic material, has good surface smoothness, and is not easy to stick to materials. In order for the increasing slide plate 4 to adapt to the arc shape of the inner wall of the rolling barrel 3, the increasing slide plate 4 is formed by splicing multiple ceramic pieces.

[0030] Optionally, the first lining plate 1 is an arc-shaped plate that matches the inner wall shape of the mixing barrel. The first lining plate 1 includes a first base plate 5, a first rubber plate 6 and a sliding plate 4 that are stacked in sequence. The first base plate 5 is connected to the inner wall of the mixing barrel.

[0031] Specifically, one side of the first substrate 5 is in conformal contact with and connected to the inner wall of the rolling barrel 3 , and the first rubber plate 6 and the increasing sliding plate 4 are sequentially conformally connected to the other side of the first substrate 5 .

[0032] Optionally, the first substrate 5 and the ceramic plate are integrally connected to the first rubber plate 6 by vulcanization, and a plurality of ceramic sheets form an arc-shaped ceramic plate on the surface of the first rubber plate 6 .

[0033] Specifically, in order to facilitate the ceramic sheets to be spliced ​​on the other side of the first substrate 5 to form the arc-shaped reinforcing plate 4 , the first substrate 5 and the reinforcing plate 4 are integrally vulcanized and connected through the first rubber plate 6 .

[0034] Optionally, the second lining plate 2 includes a second base plate 7 , second rubber plates 8 are arranged on both sides of the second base plate 7 , and reinforcing slide plates 4 are arranged on the sides of the second rubber plates 8 that are away from each other.

[0035] Specifically, the connection method of the second lining plate 2 is similar to that of the first lining plate 1. Since both side surfaces of the second lining plate 2 are in contact with the material, a structure in which two reinforcing slide plates 4 are sandwiched with a second base plate 7 is adopted to ensure the smoothness of the surfaces on both sides and avoid sticking of the material; the second rubber plate 8 is integrally vulcanized and connected to the second base plate 7 and the reinforcing slide plate 4.

[0036] In this embodiment, the first substrate 5 and the second substrate 7 are both steel plates.

[0037] Optionally, the elastic component is at least three pairs of disc springs 9, and each pair of disc springs 9 includes two disc springs 9 arranged back to back.

[0038] Specifically, at least three pairs of disc springs 9 can form a stable support between a second lining plate 2 and a first lining plate 1 .

[0039] In this embodiment, four pairs of disc springs 9 are provided.

[0040] In this embodiment, the first lining plate 1 and the second lining plate 2 are both rectangular, and the length and width dimensions are both 500 mm, and the four pairs of disc springs 9 are arranged in a rectangular array.

[0041] Optionally, a connecting rod 10 is further included, one end of which is used to connect to the inner wall of the mixing barrel, and the connecting rod 10 passes through the first lining plate 1, the second lining plate 2 and the elastic component to fix the first lining plate 1 and the second lining plate 2 in the mixing barrel.

[0042] Specifically, one end of the connecting rod 10 can be fixed on the inner wall of the rolling barrel 3, and the other end extends into the interior of the rolling barrel 3. Through holes are provided on the first lining plate 1 and the second lining plate 2. The connecting rod 10 passes through the through holes and fastens the first lining plate 1 and the second lining plate 2 through fasteners to achieve fixation of the first lining plate 1 and the second lining plate 2.

[0043] In this embodiment, the connecting rod 10 is at least partially a threaded rod, one end of which is welded to the inner wall of the rolling barrel 3. Through holes are provided in the middle of the first lining plate 1, the second lining plate 2 and the disc spring 9. The connecting rod 10 passes through the first lining plate 1, the second lining plate 2 and the disc spring 9, and is fastened by a fastening nut.

[0044] Optionally, the elastic component is in a pre-compressed state.

[0045] Specifically, the pre-compressed elastic component ensures that the first lining plate 1 and the second lining plate 2 are installed stably and have a certain vibration capacity.

[0046] The utility model also provides a mixing barrel of a sintering machine, comprising the above-mentioned anti-sticking device for the mixing barrel of the sintering machine.

[0047] Specifically, the anti-sticking device for the mixing barrel of the sintering machine is installed on the inner wall of the rolling barrel 3, moves with the operation of the rolling barrel 3, and can generate slight vibrations to avoid the formation of an annular sticking ring on the inner wall of the rolling barrel 3, thereby preventing excessive sticking at certain locations in the rolling barrel 3 of the sintering machine, thereby affecting normal production.

[0049] Specifically, when the above-mentioned anti-sticking device for the mixing barrel of a sintering machine is installed, one is set at the position of the rolling ring and the blanking ring where the material sticks seriously. The blanking ring is a circle formed by the material dropping point at the inlet of the barrel as the barrel rotates; after the above-mentioned anti-sticking device for the mixing barrel of a sintering machine is installed and put into use, the rolling ring and the blanking ring where the material sticks seriously will continue to stick. At the above-mentioned anti-sticking device for the mixing barrel of a sintering machine, since the surfaces of the first lining plate 1 and the second lining plate 2 are both ceramic, and during the operation of the rolling barrel 3, there is a deformable disc spring 9 between the first lining plate 1 and the second lining plate 2, and the second lining plate 2 will vibrate slightly during the movement. Therefore, there will be no material adhesion at this part, thus avoiding the formation of a material adhesion ring, destroying the material adhesion force generated by the formation of the material adhesion ring, so that the bonding material will not continue to bond, increase in height and thicken after being maintained at a certain height, thereby solving the problem of increasingly serious material adhesion.

[0050] The various embodiments of the utility model have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
