Technical Field

[0001] The invention relates to the technical field of stirring, and in particular to an automatic rotating material stirring device. Background Art

[0002] In the coking industry production process, the moisture and uniformity of the mixed coal are required to be high. In the case of uneven mixing, the coal collapse and heating of the coke oven will have a great impact. Some production lines have fewer belts from the mixing and batching belt to the coke oven belt, and the intermediate transfer station does not mix the materials by itself, so a set of stirring and mixing devices needs to be installed. However, the existing stirring and mixing devices have the following problems: 1. Purchasing industrial professional stirring or spiral stirring devices requires a large amount of money, which increases costs and wastes funds; 2. The existing stirring and mixing device has a complex structure, and daily maintenance also requires time-consuming and labor-intensive work, which increases construction costs. Summary of the invention

[0003] The invention provides an automatic rotating material stirring device to solve the technical problems of large consumption and high cost of the existing stirring and mixing devices.

[0004] In order to solve the above problems, the present invention provides an automatic rotating material stirring device adopting the following technical solution: An automatic rotating material stirring device includes a chute that is arranged obliquely and used to convey materials, a rotating shaft and a stirring member. The rotating shaft penetrates and is rotatably assembled in the chute. The rotating shaft is provided with a plurality of pairs of fins that are arranged at intervals along the axial direction of the rotating shaft. The two pairs of fins are arranged at intervals along the circumferential direction of the rotating shaft. The fins are slidably assembled on the rotating shaft along the radial direction of the rotating shaft. The fins include a force-bearing surface, which is arranged opposite to the material flow direction in the chute so that the material impacts the force-bearing surface to drive the rotating shaft to rotate.

[0005] The beneficial effect is: when the automatic rotating material stirring device of the present invention is used, first two rotating holes that penetrate the side wall of the chute are opened on the chute perpendicular to the material conveying direction, and then the rotating shaft is passed through the rotating holes on the side wall and rotated to be assembled on the chute. At this time, when the material is conveyed along the chute, the material impacts the force-bearing surface of the fin, thereby driving the rotating shaft to rotate. The rotation of the rotating shaft enables the fins to stir the material, thereby making the material more evenly stirred. When in use, the automatic rotating material stirring device of the present invention has a simple structure and a low price. It is also simple and convenient to maintain. It supplies energy to the fins through the impact of the material to achieve the purpose of automatic stirring and mixing, thereby reducing driving costs and saving money.

[0006] Furthermore, a connecting rod is connected between the two pairs of fins, and a plurality of connecting holes arranged at intervals along the axial direction of the rotating shaft are opened on the rotating shaft. The connecting holes radially penetrate the rotating shaft along the rotating shaft. The connecting holes correspond to the connecting rods one by one. The connecting rods are slidably assembled in the connecting holes and the fins can be stopped and cooperated with the edges of the connecting holes.

[0007] Beneficial effects: The structure is simple and easy to slide, thereby increasing the inertia of the fins when rotating around the axis of the rotating shaft, thereby increasing the stirring force of the fins on the material during the rotation of the rotating shaft, and improving the stirring efficiency and mixing effect.

[0008] Furthermore, the fin also includes a guide surface, which is arranged on the back of the force-bearing surface. The guide surface is used to stir the material and can reduce the resistance of the material when stirring the material.

[0009] Beneficial effects: The structure is simple, and it is convenient to stir the mixed materials. It can avoid the fins being too stressed when stirring the mixed materials, which may cause the rotating shaft to get stuck, and ensure that the rotating shaft can rotate.

[0010] Furthermore, the fin is an angle steel structure, the concave surface of the fin is the force-bearing surface, and the tip surface of the fin is the guide surface.

[0011] Beneficial effects: simple structure, easy to obtain materials and make.

[0012] Furthermore, a connecting plate is provided at one end of the fin facing the axis of the rotating shaft, and both ends of the connecting rod are connected together with the connecting plate of the fin at the corresponding end.

[0013] Beneficial effects: The contact area between the connecting rod and the fin is increased, thereby improving the connection stability between the fin and the connecting rod, avoiding the fin from being disconnected from the connecting rod during the mixing process, improving stability and service life, and reducing costs.

[0014] Furthermore, the extending directions of any two adjacent pairs of fins are arranged perpendicular to each other.

[0015] Beneficial effects: The structure is simple, ensuring that the material can always impact the force-bearing surface of the fin, thereby always ensuring the power of the rotating shaft to rotate due to the impact of the material.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0027] During the material conveying process, the material impacts the force-bearing surface to provide a rotational force to the rotating shaft, thereby driving the rotating shaft to rotate automatically, and then the fins stir and mix the material.

[0028] After introducing the basic principle of the present invention, various non-limiting embodiments of the present invention are described in detail below. The number of any element in the drawings is for illustration and not for limitation, and any naming is only for distinction and does not have any limiting meaning.

[0029] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0030] Embodiment 1 of an automatic rotating material stirring device provided by the present invention: like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an automatic rotating material stirring device of the present invention comprises a chute, a rotating shaft 1, a stirring member, and a support frame 8.

[0031] The chute is arranged obliquely and is used for conveying materials. Turning holes are provided on two side walls of the chute which are perpendicular to the material conveying direction.

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, two support frames 8 are provided and are respectively arranged on both sides of the two side walls of the chute with rotating holes, and a rotating seat 9 is provided on the support frame 8. A through hole 10 is provided on the rotating seat 9, and a bearing 11 is coaxially provided in the through hole 10. The outer ring of the bearing 11 is coaxially welded with the inner wall of the through hole 10.

[0033] The rotating seat 9 is detachably connected to the support frame 8 by bolts 12, so that it is convenient for workers to disassemble and maintain the rotating seat 9; the structure is simple, easy to install and manufacture; and it is easy to disassemble the rotating seat 9 for maintenance and replacement.

[0034] The two ends of the rotating shaft 1 are arranged one by one with the two rotating seats 9 and are rotatably assembled on the corresponding rotating seats 9. The two ends of the rotating shaft 1 are coaxially welded with the inner ring of the bearing 11 on the corresponding side. The rotating shaft 1 is provided with a plurality of connecting holes 6 arranged at intervals along the axial direction of the rotating shaft 1, and the axes of any two adjacent connecting holes 6 are arranged perpendicular to each other, so that the rotation is stable, the service life is improved, and the resistance is reduced, so as to ensure that the rotating shaft 1 can rotate and avoid the rotating shaft 1 being stuck.

[0035] like Figure 3 and Figure 5As shown, the stirring member includes a plurality of connecting rods 5 corresponding one-to-one with the connecting holes 6, and a plurality of pairs of fins 2 corresponding one-to-one with the connecting holes 6. The connecting rods 5 are coaxially slidably assembled in the corresponding connecting holes 6, and both ends of the connecting rods 5 extend to the outside of the connecting holes 6. Each connecting rod 5 is arranged in a one-to-one correspondence with each pair of fins 2. When the connecting rods 5 slide in the connecting holes 6, the fins 2 can be stopped and cooperated with the edges of the connecting holes 6 to prevent the connecting rods 5 or the fins 2 from detaching from the rotating shaft 1.

[0036] like Figure 5 As shown, the fins 2 are made of metal and include two side plates arranged perpendicularly to each other. In this embodiment, 7 pairs of fins 2 are arranged on the rotating shaft 1, and any two adjacent pairs of fins 2 are arranged perpendicularly to each other, and any two adjacent pairs of fins 2 are arranged at equal intervals.

[0037] In this embodiment, the fins 2 are made of angle steel, and a connecting plate 7 is provided at one end of the two fins 2 in a pair, and the connecting plate 7 is a triangular plate. The two connecting plates 7 of the two fins 2 in a pair are respectively connected to the two ends of the corresponding connecting rod 5, so as to increase the contact area at the connection between the connecting rod and the fin, thereby improving the connection stability between the fin and the connecting rod, avoiding the fin from being disconnected from the connecting rod during the mixing process, improving stability and service life, and reducing costs. The two fins 2 in a pair are arranged at intervals along the circumferential direction of the rotating shaft 1.

[0038] In this embodiment, the concave surface of the above-mentioned angle steel is the force-bearing surface 3, and the force-bearing surface 3 is arranged opposite to the flow direction of the material in the chute so that the material impacts on the force-bearing surface 3 to drive the rotating shaft 1 to rotate; the tip surface of the above-mentioned angle steel is the guide surface 4, and the guide surface 4 is used to stir the material and can reduce the resistance of the material when stirring the material; the force-bearing surface 3 of one fin 2 of the two paired fins 2 is arranged in the same direction as the guide surface 4 of the other fin 2, which is convenient for stirring the mixed material and avoids the rotating shaft being stuck due to excessive force on the fin when stirring the mixed material, thereby ensuring that the rotating shaft can rotate.

[0039] When the angle steel is in use, the structure is simple and the materials are easy to obtain and manufacture; it is convenient to stir the mixed materials, avoid the fins being subjected to too much force when stirring the mixed materials and causing the rotating shaft to be stuck, and ensure that the rotating shaft can rotate; it is convenient to slide, thereby increasing the inertia of the fins when rotating around the axis of the rotating shaft, thereby increasing the stirring force of the fins on the material during the rotation of the rotating shaft, and improving the stirring efficiency and mixing effect; the extension directions of any two adjacent pairs of fins are arranged perpendicular to each other to ensure that the material can always impact the force-bearing surface of the fin, thereby always ensuring the power of the rotating shaft to rotate due to the impact of the material.

[0040] When an automatic rotating material stirring device of the present invention is used, firstly, two rotating holes penetrating the side wall of the chute are opened on the chute along a direction perpendicular to the material conveying direction, and then the rotating shaft 1 passes through the rotating holes on the side wall and is rotatably assembled on the chute. At this time, when the material is conveyed along the chute, the material impacts the force-bearing surface 3 of the fin 2, thereby driving the rotating shaft 1 to rotate. The rotation of the rotating shaft 1 enables the fin 2 to stir the material, thereby making the material stirring more uniform.

[0041] The automatic rotating material stirring device of the present invention has a simple structure and low price when in use, and is simple and convenient to maintain. The fins 2 are powered by the impact of the material to achieve the purpose of automatic stirring and mixing, thereby reducing driving costs and saving money. At the same time, when the rotating shaft 1 rotates, the fins 2 under the impact of the material are affected by gravity as the rotating shaft 1 rotates, causing the connecting rod 5 to slide in the connecting hole 6, thereby causing the fins 2 under the impact of the material to move away from the axial direction of the rotating shaft 1, thereby increasing the impact area of ​​the fins 2 under the impact of the material, and can also increase the inertia of the fins 2 under the impact of the material as the rotating shaft 1 rotates, thereby reducing the probability of the rotating shaft 1 getting stuck.

The connecting rods are slidably assembled in the connecting holes and the fins can be stopped and matched with the edges of the connecting holes.
