Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of quenching equipment, in particular to a heating device and a mill ball quenching equipment. BACKGROUND

[0002] As an indispensable spare part in the mineral processing industry, the metal mill ball is the largest consumable in the material of the mineral processing industry. The quality of the mill ball directly affects the grinding efficiency, the procurement cost. In order to improve the hardness of the metal mill ball, quenching process has become a common way to improve the hardness of the mill ball. Quenching can not only change the microstructure of the metal material, but also significantly improve its mechanical properties, and is widely used in the fields of automobiles, aerospace and precision instruments.

[0003] At present, the quenching and heating process of the metal mill ball is usually carried out by using a push rod type quenching furnace. This method is to place a mill ball containing frame on a conveying device, and then send multiple mill ball containing frames into the furnace at a preset temperature for heating. During the heating process, the mill ball containing frame moves with the conveying device to ensure that all mill ball containing frames can uniformly pass through the high temperature zone, thereby completing the entire heating process. This method is widely used in production lines because of its simple operation and easy automation control.

[0004] However, in this quenching and heating method, the mill ball does not rotate when heated in the frame, which may cause uneven heating of the mill ball in the frame, high temperature heating on the surface of the frame, and low temperature heating of the mill ball in the middle of the frame. It is inevitable to cause uneven heating of the mill ball, which affects the consistency of the quenching effect of the mill ball. In addition, since the frame also needs to be heated in a high temperature environment together with the mill ball, the weight of the frame is almost equal to the weight of the mill ball in the frame, which leads to additional energy consumption.

[0046] Embodiment one

[0047] As shown in Figures 1-4 The first aspect of the present disclosure provides a heating device, which comprises a containing assembly 1 and a bearing assembly 2; The containing assembly 1 is internally provided with a cylindrical heating space A, and a threaded structure 11 is arranged on the side wall inside the heating space A; The bearing assembly 2 is provided with a plurality of heating components 21, the heating end of the heating component 21 is attached to the containing assembly 1 to heat the inside of the heating space A, and the containing assembly 1 is rotationally connected with the bearing assembly 2 to drive the containing assembly 1 to rotate, so that the material can move from one end to the other end of the heating space A through the threaded structure 11.

[0048] Specifically, the main body of the containing assembly 1 can be a cylindrical structure or a square cylindrical structure, the inner cylinder of the square cylindrical structure has a circular cross section, and a cover door 3 can be arranged at both ends of the square cylindrical structure or the cylindrical structure, which is not specifically limited. In the embodiment, the main body of the containing assembly 1 can adopt a cylindrical structure, and a threaded structure 11 is arranged in the inner wall of the containing assembly 1. The threaded structure 11 forms a threaded groove on the inner wall of the heating space A, and the depth and width of the threaded groove are not specifically limited, which can accommodate at least two materials.

[0049] The bearing assembly 2 can be a bearing support, and the bearing is directly connected to the containing assembly 1 through a plurality of bearings. The heating component 21 can be an electric heating device or a fuel heating device, which is not specifically limited, and in the embodiment, a resistance wire can be used as the heating component 21. The heating end of the heating component 21 is attached to the outer surface of the containing assembly 1 to heat the entire containing assembly 1, thereby heating the inside of the heating space A. For driving the containing assembly 1 to rotate, a servo motor can be used, or a rotating rod can be provided for manual driving, and the rotation driving mode is not specifically limited. When the number of materials is large and the weight of the materials is large, the length direction of the heating space A of the containing space can be parallel to the horizontal plane.

[0050] The heating device provided by the first aspect of the present disclosure comprises a containing assembly 1 and a bearing assembly 2. The containing assembly 1 has a cylindrical heating space A, and a threaded structure 11 is arranged on the inner wall of the heating space A. The containing assembly 1 has a plurality of heating components 21, the heating end of the heating component 21 is attached to the containing assembly 1, and the heating space A of the containing assembly 1 is heated. The containing assembly 1 is rotationally connected to the bearing assembly 2, and the containing assembly 1 is driven to rotate on the bearing assembly 2. The threaded structure 11 arranged on the inner side wall of the heating space A rotates, the materials enter from one end of the heating space A, move to the other end of the heating space A along with the rotation of the threaded structure 11, and the materials rotate during the movement, so that the materials are transported and heated during the quenching process, the heating of the materials is more uniform, a material frame is not needed, energy waste is effectively reduced, only the containing assembly 1 needs to be sealed, the entire heating device does not need to be sealed, and the cost is effectively reduced.

[0051] As shown in Figure 2 , 3 in some embodiments, the heating space A is inclined vertically downward from one end to the other end, and the threaded depth of the threaded structure 11 gradually decreases from one end to the other end of the heating space A.

[0052] Specifically, one end and the other end of heating space A refer to the two ends along the length of the cylindrical heating space A. One end of heating space A is where the material enters, while the other end is where the material flows out. Heating space A is tilted vertically downwards from one end to the other, so that the length of heating space A forms a preset angle with the horizontal direction. This preset angle is acute, typically greater than 0° and less than 30°. The specific preset angle can be selected according to the actual situation. When the material is light and the quantity is small, the preset angle can be set slightly larger, for example, 28° or 29°. When the material is heavy and the quantity is small, the preset angle can be set slightly smaller, for example, 1° or 2°. The quantity and quality of the material can be specifically defined based on the state of the material in heating space A during actual operation. The preset angle can be formed by setting support legs 23 of different heights in the bearing component 2. The support legs 23 can also be telescopic rods to facilitate adjustment of the preset angle.

[0053] The threaded structure 11 gradually decreases in depth from one end of the heating space A to the other. This is because when material enters the heating space A from one end, it collides with the inner wall of the heating space A and the threaded structure 11, causing it to be ejected towards the other end of the heating space A. Setting the threaded groove formed by the threaded structure 11 at one end of the heating space A to be deeper effectively prevents the material from being ejected due to collision. Meanwhile, at the other end of the heating space A, which serves as the material outlet, setting the threaded groove formed by the threaded structure 11 to be shallower facilitates the flow of material out of the heating space A.

[0054] like Figure 1 , 3 As shown, in some embodiments, the heating space A includes a first sub-heating space A1, a second sub-heating space A2, and a third sub-heating space A3. The first sub-heating space A1 and the third sub-heating space A3 are respectively disposed on both sides of the second sub-heating space A2. The first sub-heating space A1 and the third sub-heating space A3 are respectively provided with a material inlet 12 and a material outlet 13 that communicate with the outside. The second sub-heating space A2, the first sub-heating space A1, and the third sub-heating space A3 are respectively connected through a first material connection port 14 and a second material connection port 15.

[0055] Specifically, the accommodating assembly 1 can be composed of three cylinders, the first and second cylinders are cylinders with one side opening, and the third cylinder is a cylinder with two side openings, the first and second cylinders are arranged on both sides of the third cylinder respectively, and the openings are arranged opposite to each other, the interiors of the first and second cylinders can be used as the first and second sub-heating spaces A1 and A2 respectively, and the openings thereof can be used as the material inlet 12 and the material outlet 13 respectively, and the cover doors 3 can be installed on the material inlet 12 and the material outlet 13, and the interior space of the third cylinder can be used as the third sub-heating space A3, and openings can be arranged at the bottoms of the first and second cylinders to be used as the first and second material communication ports 14 and 15 respectively. The first and second material communication ports 14 and 15 are located in the thread groove formed by the thread structure 11 and do not contact the groove wall of the thread groove, and it is necessary to ensure that the material can pass through the first or second material communication port 14 or 15 in the thread groove. At the same time, the thread structure 11 and the material outlet 13 can be adjusted according to the setting, so that the thread structure 11 can make the material flow out of the material outlet 13 during rotation.

[0056] As shown in Figure 1 , in some embodiments, the material outlet 13, the material inlet 12, the first material communication port 14 and the second material communication port 15 are staggered.

[0057] Specifically, the sizes of the material outlet 13, the material inlet 12, the first material communication port 14 and the second material communication port 15 are all smaller than the size of the length direction cross section of the heating space A, and the projections of the material outlet 13, the material inlet 12, the first material communication port 14 and the second material communication port 15 on any cross section in the length direction of the heating space A do not intersect. In this way, during the operation of the heating device, the cover door 3 of the material inlet 12 is opened, and when the material is added from the material inlet 12 of the first sub-heating space A1, the influence on the material being heated in the second sub-heating space A2 can be reduced. Similarly, the cover door 3 of the material outlet 13 is opened, and when the material flows out of the material outlet 13 of the third sub-heating space A3, the influence on the material being heated in the second sub-heating space A2 can also be reduced.

[0058] As shown in Figure 1 , 3As shown, in some embodiments, the containing assembly 1 comprises: a first cylindrical structure 16, two first baffles 17, two second baffles 18; the first cylindrical structure 16 has openings at both ends, and the inside constitutes a heating space A; the two first baffles 17 are arranged inside the heating space A, and divide the heating space A into a first sub-heating space A1, a second sub-heating space A2 and a third sub-heating space A3, and the two first baffles 17 are respectively provided with a first material communication port 14 and a second material communication port 15; the two second baffles 18 respectively cover the two openings of the first cylindrical structure 16, and the two second baffles 18 are rotationally connected with the first cylindrical structure 16, and the two second baffles 18 are fixedly connected with the bearing assembly 2, and the two second baffles 18 are respectively provided with a material inlet 12 and a material outlet 13.

[0059] Specifically, the two first baffles 17 divide the heating space A, and the connection mode of the two first baffles 17 with the first cylindrical structure 16 can be welding or clamping by setting a clamping groove, and is not specifically limited. The first material communication port 14 is arranged on the first baffle 17 close to one end of the first cylindrical structure 16, and the second material communication port 15 is arranged on the first baffle 17 close to the other end of the first cylindrical structure 16, and the first material communication port 14 and the second material communication port 15 are respectively located at the edge position of the first baffle 17. It should be noted that after the first baffle 17 is installed, the material on the threaded structure 11 can pass through the first material communication port 14 and the second material communication port 15.

[0060] The connection mode of the second baffle 18 with the first cylindrical structure 16 is realized by bearing to rotationally connect the two, or can be realized by gap fit to rotationally connect the two, and is not specifically limited. The material inlet 12 is arranged at a position close to one end of the first cylindrical structure 16, and the specific position of the material outlet 13 is not limited. The material outlet 13 is arranged at a position close to the other end of the first cylindrical structure 16, and the arrangement position of the material outlet 13 needs to ensure that the material can flow out from the material outlet 13 through the rotation of the threaded structure 11. The fixed connection between the second baffle 18 and the bearing assembly 2 can be welding or realized by screws, and is not specifically limited.

[0061] In the working process, the first baffle 17 rotates with the first cylindrical structure 16, and the second cylindrical structure 22 does not rotate with the first cylindrical structure 16, and at the same time, the cover door 3 of the material inlet 12 and the material outlet 13 can be set as an electric cover door 3 to facilitate the entry and exit of the material. In this way, the structure of the containing assembly 1 is simple and has high strength, and at the same time, the second baffle 18 does not rotate with the first cylindrical structure 16, which can facilitate the wiring of the electronic elements on the second baffle 18.

Meanwhile, a limiting component 29 can be arranged on the second cylindrical structure 22 or the first cylindrical structure 16 to limit the relative movement of the first cylindrical structure 16 and the second cylindrical structure 22 in the axial direction thereof. In the embodiment, the second cylindrical structure 22 and the second baffle 18 can be fixedly connected through the connecting rod 27.

[0064] A plurality of mounting grooves can be arranged on the inner wall of the second cylindrical structure 22, and the heating components 21 are arranged in the mounting grooves to realize that the heating components 21 can abut against the outer surface of the containing assembly 1 and heat the heating space A. The plurality of support legs 23 are not specifically limited and can only provide stable support for the second cylindrical structure 22. The support legs 23 can be telescopic rods, and the telescopic rods are adjusted to realize that the length direction of the second cylindrical structure 22 forms a preset angle with the horizontal direction, so that the heating space A forms a preset angle with the horizontal direction. The connection mode between the plurality of support legs 23 and the second cylindrical structure can be bolt connection or rivet connection, which is not specifically limited.

The two gear ring structures 24 are sleeved on both ends of the first cylindrical structure 16 protruding from the second cylindrical structure 22, and are fixedly connected with the first cylindrical structure 16 and rotate together with the first cylindrical structure 16.
