Description

Technical Field

[0001] The utility model relates to the technical field of powder processing, and particularly relates to a powder surface treatment device. Background Technique

[0002] With the wide application of heat-conducting powder in industry, the requirements for its heat conduction and mechanical properties are getting higher and higher, and the difficulty of surface treatment of heat-conducting powder is increasing day by day. There are many dead corners in traditional paddle equipment, such as the bottom and side walls. It is difficult for the force of the paddle to reach the bottom, resulting in a layer of dead material at the bottom, which affects the overall performance of the powder. Although spoiler plates are provided on the side walls to change the flow state during the surface treatment of the powder, the surface treatment of small-particle-size powder is not ideal, and the properties such as the viscosity and heat conduction of the powder are relatively poor.

[0003] Based on the above description, the present invention provides a powder surface treatment device with a simpler structure, suitable for surface treatment of powders of various particle sizes, high efficiency, and stable performance. Content of the Utility Model

[0004] The purpose of the utility model is to provide a powder surface treatment device, which can simultaneously improve the properties of the powder such as heat conduction, extrusion, and operability, make the powder more stable, and can also improve the timeliness of the powder to a certain extent, solving the problem that the treatment effect of the existing powder surface treatment device is not ideal.

[0005] To achieve the above object, the utility model provides the following technical solution: A powder surface treatment device, including a two-stage reducer, a power part cooperating with the two-stage reducer, a bottom support and a control unit. There are two bottom supports in total and they are designed in parallel. The two-stage reducer is fixedly installed on one of the bottom supports. A fixing frame is integrally welded below the two-stage reducer, and the fixing frame is welded to the bottom support, so as to strengthen the structure of the two-stage reducer by using the fixing frame. The two ends of the two-stage reducer are respectively connected to the power part and a gear. When the power part operates, the two-stage reducer can drive the gear to rotate. Bearings are installed on both bottom supports, and shafts are installed in cooperation with both bearings. The gear is fixedly installed on one of the shafts and is connected to the two-stage reducer. Both shafts are fixedly installed with the paddle-type processing equipment main body. The paddle-type processing equipment main body is fixed on the bottom support through the shafts and bearings, so that the two shafts can drive the paddle-type processing equipment main body to flip accordingly, to ensure the stability of the structures on both sides of the paddle-type processing equipment main body, so that when the gear rotates, it can drive the shaft and the paddle-type processing equipment main body to flip. The paddle-type processing equipment main body is connected through the gear on the two-stage reducer and is controlled by the control unit. The height at which the bottom support fixes the paddle-type processing equipment main body is one-half of the total height of the paddle-type processing equipment main body, that is, the position where the shaft is connected to the paddle-type processing equipment main body is the central position of the paddle-type processing equipment main body. The two-stage reducer adopts a large speed ratio (1:50). The design purpose of the two-stage reducer is to increase the torque when the paddle-type processing equipment main body rotates. The power part mainly has a motor drive and a power-off locking function. The operation of the paddle-type processing equipment main body is executed by the control unit. Through the control unit, the swing amplitude (the maximum swing angle is 120°), swing speed and swing times can be set. For safety considerations, this technical solution is equipped with a mechanical locking function, and automatically stops working in case of power-off and overload. The design concept of this equipment structure is based on the paddle-type processing equipment main body. The paddle-type processing equipment main body is connected through the shaft on the bottom support, perpendicular to the ground. The power part acts on the paddle-type processing equipment main body through the two-stage reducer, and its movement speed and maximum stroke are controlled by the control unit. The powder at the bottom and side walls of the paddle-type processing equipment main body changes the flow state during the powder surface treatment process under the action of gravity, reduces the dead corners of the paddle-type processing equipment main body, and gives the powder a greater and comprehensive acting force within the predetermined powder surface modification time. A powder processing motor is fixed on the top of the paddle-type processing equipment main body. The powder processing motor needs to be driven by an external power source, and a multi-group of inner support shafts are connected below the output shaft body of the powder processing motor. Multiple groups of paddles are installed on the inner support shafts. Multiple groups of annular material guiding seats are also welded in the inner cavity of the paddle-type processing equipment main body, and each material guiding seat has multiple groups of guiding inner walls.

[0006] As a preferred implementation: Two groups of feeding pipes are fixedly connected to the top wall of the paddle-type processing equipment main body; through the two groups of feeding pipes, the powder raw materials to be processed can be continuously fed into the paddle-type processing equipment main body.

[0007] As a preferred embodiment: a discharge pipe is connected to the center of the bottom of the blade-type processing equipment main body; the discharge pipe is used to output the powder after surface treatment.

[0008] As a preferred embodiment: a bottom support rod is welded to the bottom of the inner cavity of the blade-type processing equipment main body, and the inner support shaft is rotatably installed on the bottom support rod; thus, the bottom of the inner support shaft is kept stable and rotates smoothly by using the bottom support rod.

[0009] As a preferred embodiment: multiple groups of blades are evenly distributed on the inner support shaft, and the inner support shaft is vertically designed in the inner cavity of the blade-type processing equipment main body; so that multiple groups of blades act together to continuously and repeatedly perform surface treatment work on the powder in the inner cavity of the blade-type processing equipment main body.

[0010] As a preferred embodiment: the multiple guiding inner walls on the guiding seat are gradually slowed down from top to bottom; thereby, the powder is repeatedly slapped by the multiple guiding inner walls with different angles, which is beneficial to slap and crush the powder falling on the edge of the inner cavity of the blade-type processing equipment main body and reduce the probability of powder caking.

[0011] As a preferred embodiment: the single-side swing angle of the blade-type processing equipment main body is 60°, and the total swing angle is 120°.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: the present utility model can greatly improve the surface treatment performance of the powder, such as the viscosity of the heat-conducting powder for potting glue. The structure of this equipment can simultaneously improve the heat conduction, extrusion, operability and other properties of the powder, make the powder more stable, and can also improve the timeliness of the powder to a certain extent.

[0021] Please refer to Figures 1 to 4, an embodiment provided by the present utility model: a powder surface treatment device, including a two-stage reducer 2, a power part 3 cooperating with the two-stage reducer 2, a bottom support 4, and a control unit 5. There are two bottom supports 4 in total and they are designed in parallel. The two-stage reducer 2 is fixedly installed on one of the bottom supports 4. A fixing frame 8 is integrally welded below the two-stage reducer 2, and the fixing frame 8 is welded to the bottom support 4, so as to strengthen the structure of the two-stage reducer 2 by using the fixing frame 8. The two ends of the two-stage reducer 2 are respectively connected to the power part 3 and a gear 7. When the power part 3 operates, the two-stage reducer 2 can be used to drive the gear 7 to rotate. Bearings 6 are installed on both of the two bottom supports 4, and shafts 9 are installed in cooperation with both of the two bearings 6. The gear 7 is fixedly installed on one of the shafts 9 and is connected to the two-stage reducer 2. Both of the two shafts 9 are fixedly installed with the blade-type treatment device main body 1. The blade-type treatment device main body 1 is fixed on the bottom support 4 through the shafts 9 and the bearings 6, so that the two shafts 9 can drive the blade-type treatment device main body 1 to flip accordingly, to ensure the stability of the structures on both sides of the blade-type treatment device main body 1, so that when the gear 7 rotates, it can drive the shafts 9 and the blade-type treatment device main body 1 to flip. The unilateral swing angle of the blade-type treatment device main body 1 is 60°, and the total swing angle is 120°. The blade-type treatment device main body 1 is connected through the gear 7 on the two-stage reducer 2 and is controlled by the control unit 5. The height at which the bottom support 4 fixes the blade-type treatment device main body 1 is one-half of the total height of the blade-type treatment device main body 1, that is, the position where the shaft 9 is connected to the blade-type treatment device main body 1 is the central position of the blade-type treatment device main body 1. The two-stage reducer 2 adopts a large speed ratio (1:50);

[0022] Two groups of feeding pipes 10 are fixedly connected to the top wall of the blade-type processing equipment main body 1. Through the two groups of feeding pipes 10, the powder raw materials to be processed can be continuously fed into the blade-type processing equipment main body 1. A discharge pipe 11 is connected to the center of the bottom of the blade-type processing equipment main body 1, and the discharge pipe 11 is used to output the surface-treated powder. A powder processing motor 12 is fixed on the top of the blade-type processing equipment main body 1. The powder processing motor 12 needs to be driven by an external power source, and an inner support shaft 13 is connected below the output shaft body of the powder processing motor 12. A plurality of groups of blades 14 are installed on the inner support shaft 13. A bottom support rod 15 is welded to the bottom of the inner cavity of the blade-type processing equipment main body 1, and the inner support shaft 13 is rotatably installed on the bottom support rod 15. Therefore, the bottom of the inner support shaft 13 is kept stable and rotates smoothly by using the bottom support rod 15. The multiple groups of blades 14 are evenly distributed on the inner support shaft 13, and the inner support shaft 13 is vertically designed in the inner cavity of the blade-type processing equipment main body 1, so that the multiple groups of blades 14 work together to continuously and repeatedly perform surface treatment work on the powder in the inner cavity of the blade-type processing equipment main body 1. A plurality of groups of annular guide seats 16 are also welded in the inner cavity of the blade-type processing equipment main body 1. Each guide seat 16 has a plurality of guiding inner walls 1601. The plurality of guiding inner walls 1601 on the guide seat 16 are gradually slowed down from top to bottom, so as to slap the powder multiple times by using the guiding inner walls 1601 with different angles, which is beneficial to slapping and crushing the powder falling on the edge of the inner cavity of the blade-type processing equipment main body 1 and reducing the probability of powder caking.

[0023] In the operation of this utility model, in its structure, the design purpose of the secondary reducer 2 is to increase the torque when the main body 1 of the blade-type processing equipment rotates. The power part 3 mainly has the functions of motor drive and power-off locking. The operation of the main body 1 of the blade-type processing equipment is executed by the control unit 5. Through the control unit 5, the amplitude of swing (the maximum swing angle is 120°), the swing speed and the number of swings can be set. For safety considerations, this technical solution is equipped with a mechanical locking function and will automatically stop working in case of power failure and overload. The design concept of this equipment structure is based on the main body 1 of the blade-type processing equipment. The main body 1 of the blade-type processing equipment is connected through the shaft 9 on the bottom support 4, perpendicular to the ground. The power part 3 acts on the main body 1 of the blade-type processing equipment through the secondary reducer 2. The movement speed and the maximum stroke are controlled by the control unit 5. The powder at the bottom and the side wall of the main body 1 of the blade-type processing equipment changes the flow state during the surface treatment process of the powder under the action of gravity, reducing the dead angle of the main body 1 of the blade-type processing equipment. Within the predetermined powder surface modification time, a greater and more comprehensive acting force is applied to the powder. After the powder enters the main body 1 of the blade-type processing equipment from the feed pipe 10, driven by the powder processing motor 12, the inner support shaft 13 and multiple groups of blades 14 rotate at high speed to perform surface property treatment on the powder. At the same time, the powder falling on the inner cavity edge of the main body 1 of the blade-type processing equipment is affected by the guiding inner wall 1601 of multiple groups of guiding seats 16, and the powder is slapped to reduce caking.
