Description

Technical Field

[0001] This utility model relates to the field of polishing abrasive mixing technology, specifically to a pneumatic polishing abrasive mixing device. Background Technology

[0002] There are many types of polishing materials, generally categorized as: polishing wax, polishing cloth wheels, nylon wheels, sisal wheels, thread wheels, blower wheels, mixed cloth wheels, etc. Polishing materials are used to polish materials such as glass, metal, leather, semiconductors, plastics, gemstones, jade, and stainless steel. The abrasives in polishing materials are mainly diamond, alumina, chromium oxide, iron oxide, and magnesium oxide. Abrasives are broadly classified into natural and synthetic abrasives, and are sharp, hard materials used to grind softer material surfaces. Existing polishing materials require abrasive formulation during processing to adapt them to different working conditions.

[0003] Existing mechanical mixing devices are prone to segregation during the mixing process for materials with large density differences or uneven particle size distribution, especially when mixing heavy abrasives and light powders. The heavy components settle at the bottom of the tank while the light components float to the top, which easily leads to uneven mixing. Therefore, it is particularly important to improve the existing mixing devices and design a new type of pneumatic polishing abrasive mixing device to solve the above-mentioned technical defects and improve the practicality of the overall mixing device. Utility Model Content

[0004] The purpose of this invention is to provide a pneumatic polishing abrasive mixing device that solves the problem that existing mechanical mixing devices are prone to segregation during the mixing process of materials with large density differences or uneven particle size distribution, especially the mixing of heavy abrasives and light powders. The heavy components settle at the bottom of the tank while the light components float, which easily leads to uneven mixing.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pneumatic polishing abrasive mixing device includes a mixing tank body, a connecting block fixedly connected to the top of the mixing tank body, a sand inlet and a powder inlet respectively opened at both ends of the connecting block, an air inlet opened at the top of the connecting block, and a stirring assembly provided inside the mixing tank body;

[0007] The stirring assembly is used to stir and mix the powder introduced into the mixing tank body. The stirring assembly includes a rotating rod rotatably connected to the inside of the mixing tank body. A stirring rod is fixedly connected to the top of the rotating rod. A fixing frame is fixedly connected to the outside of the rotating rod. Multiple sets of extension rods are fixedly connected to both ends of the fixing frame. A rotating plate is fixedly connected to the end of the extension rod away from the fixing frame.

[0008] As a preferred embodiment of this utility model, both the rotating rod and the fixed frame have cavities inside, and the two sets of cavities are interconnected.

[0009] As a preferred embodiment of this utility model, conveying grooves are provided on both sides inside the extension rod, and the conveying grooves extend into the interior of the fixing frame and communicate with the cavity.

[0010] As a preferred embodiment of this utility model, a guide fan is fixedly connected to the bottom end of the outer side of the rotating rod and the inner side of the fixed frame. The guide fan has multiple sets of spray holes inside, and the multiple sets of spray holes are interconnected with the cavity.

[0011] As a preferred embodiment of this utility model, the rotating rod extends to the bottom end of the mixing tank body and is fixedly connected to a first synchronous wheel. A synchronous belt is provided on the outer side of the first synchronous wheel, and a second synchronous wheel is provided at the end of the synchronous belt away from the first synchronous wheel. The drive end of a drive motor is fixedly connected inside the second synchronous wheel.

[0012] As a preferred embodiment of this utility model, a connecting shell is fixedly connected to the bottom of the mixing tank body and outside the first synchronous pulley, the synchronous belt and the second synchronous pulley. The drive motor is fixedly connected to the connecting shell, and the rotating rod extends to the bottom of the mixing tank body and is rotatably connected to the first air inlet pipe.

[0013] As a preferred embodiment of this utility model, a second air inlet pipe is fixedly connected to the top of the air inlet, and a mixing pipe is fixedly connected to the inside of the mixing tank body through the connecting block. The air inlet, sand inlet, and powder inlet are interconnected.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, the design of the stirring assembly enables the drive motor to rotate the rotating rod via a synchronous pulley and belt. The rotating rod, in turn, rotates the top stirring rod, the middle fixing frame, the extension rod, and the end rotating plate. These components mechanically shear, tumble, and mix the materials in different areas from the center to the edge of the tank, completing the initial mixing process. Compressed gas enters the cavity inside the rotating rod from the first air inlet pipe at the bottom. The airflow flows upward, passes through the cavity into the fixing frame, and then is distributed to the conveying grooves of each extension rod. Finally, the airflow is ejected at high speed from the outlet of the conveying groove on the extension rod. The airflow ejected from the extension rod blows directly onto the materials inside the mixing tank, especially the materials located in the middle of the tank, causing them to be fully agitated and dusted, breaking up the agglomeration and static accumulation of the materials, and greatly improving the contact and mixing efficiency between powders. Part of the airflow is ejected through the nozzles on the guide fan at the bottom of the rotating rod. As the fan rotates, the airflow forms an upward rotating airflow at the bottom of the tank, effectively blowing up the heavier particles deposited at the bottom and re-entraining them into the mixing vortex. This completely solves the problem of dead zones in the bottom sedimentation area. The dual mixing mode of mechanical and pneumatic forces means that the mechanical components are responsible for macroscopic agitation and mixing, while the airflow is responsible for microscopic dust dispersion and homogenization. The two work together to make the mixing speed faster and the uniformity higher. Compared with simply increasing the mechanical stirring speed to achieve the same mixing effect, introducing airflow to assist dust dispersion can achieve efficient mixing at a relatively low mechanical speed, reducing the power consumption of the drive motor and resulting in significant energy savings.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] A pneumatic polishing abrasive mixing device includes a mixing tank body 1, a connecting block 2 fixedly connected to the top of the mixing tank body 1, a sand inlet 3 and a powder inlet 4 respectively opened at both ends of the connecting block 2, an air inlet 5 opened at the top of the connecting block 2, and a stirring assembly 6 provided inside the mixing tank body 1.

[0025] The stirring assembly 6 is used to stir and mix the powder introduced into the mixing tank body 1. The stirring assembly 6 includes a rotating rod 7 rotatably connected to the inside of the mixing tank body 1. A stirring rod 8 is fixedly connected to the top of the rotating rod 7. A fixing frame 9 is fixedly connected to the outside of the rotating rod 7. Multiple extension rods 10 are fixedly connected to both ends of the fixing frame 9. A rotating plate 11 is fixedly connected to the end of the extension rod 10 away from the fixing frame 9.

[0026] Furthermore, both the rotating rod 7 and the fixed frame 9 have cavities 12 inside, and the two sets of cavities 12 are interconnected. Both sides of the extension rod 10 have conveying grooves 13 inside, which extend into the fixed frame 9 and are interconnected with the cavities 12. Gas is introduced into the rotating rod 7, and through the cavity 12 inside the rotating rod 7, the gas can be introduced into the fixed frame 9. In conjunction with the cavity 12 inside the fixed frame 9, the gas is introduced into the extension rod 10. Through the conveying groove 13, the gas can be ejected to blow air into the interior of the mixing tank body 1. When the powder is stirred, the powder is lifted up. The two work together to effectively mix the powder.

[0027] A guide fan 14 is fixedly connected to the bottom of the outer side of the rotating rod 7 and the inner side of the fixed frame 9. The guide fan 14 has multiple sets of nozzles 15 inside, which are connected to the cavity 12. When the rotating rod 7 rotates, it drives the guide fan 14 to rotate. At the same time, when gas is introduced into the interior of the rotating rod 7, it is introduced into the interior of the multiple sets of nozzles 15, generating rising gas at the bottom of the mixing tank body 1. This prevents the gas from settling at the bottom of the mixing tank body 1, making the mixing more thorough and uniform, with lower power consumption and higher mixing efficiency.

[0028] Secondly, a first synchronous pulley 16 is fixedly connected to the bottom end of the mixing tank body 1 via the rotating rod 7. A synchronous belt 17 is provided on the outer side of the first synchronous pulley 16. A second synchronous pulley 18 is provided at the end of the synchronous belt 17 away from the first synchronous pulley 16. The drive end of the drive motor 19 is fixedly connected inside the second synchronous pulley 18. A connecting shell 20 is fixedly connected to the bottom of the mixing tank body 1, located outside the first synchronous pulley 16, the synchronous belt 17, and the second synchronous pulley 18. The drive motor 19 is fixedly connected to the connecting shell 20. A first air inlet pipe 2 is rotatably connected to the bottom end of the mixing tank body 1 via the rotating rod 7. 1. Start the drive motor 19 to drive the first synchronous pulley 16 to rotate. The synchronous belt 17 drives the first synchronous pulley 16 to rotate, so that the rotating rod 7 can rotate, which drives the stirring rod 8 to rotate, and stirs the powder introduced into the mixing tank body 1. At the same time, the rotation of the rotating rod 7 drives the fixed frame 9 to rotate, so that multiple sets of extension rods 10 drive the rotating plate 11 to move in an arc shape around the rotating rod 7, effectively stirring the powder. The first air inlet pipe 21 is rotatably connected to the rotating rod 7, and gas can be introduced into the interior of the rotating rod 7 through the first air inlet pipe 21.

[0029] Furthermore, a second air inlet pipe is fixedly connected to the top of the air inlet 5, and a mixing pipe 22 is fixedly connected to the inside of the mixing tank body 1 extending from the connecting block 2. The air inlet 5, sand inlet 3, and powder inlet 4 are interconnected. The two materials are introduced into the inside of the connecting block 2 through the sand inlet 3 and the powder inlet 4, respectively. Gas is introduced into the inside of the air inlet 5 through the second air inlet pipe, so that the powder introduced into the inside of the connecting block 2 can be guided and introduced into the inside of the mixing pipe 22, so that the powder can be introduced into the inside of the mixing tank body 1 for mixing and stirring.

[0030] In this embodiment, the specific implementation scenario is as follows: In actual use, two materials are introduced into the interior of the connecting block 2 through the sand inlet 3 and the powder inlet 4, respectively. Gas is introduced into the interior of the air inlet 5 through the second air inlet pipe, which guides the powder introduced into the connecting block 2 and guides it into the mixing pipe 22, allowing the powder to be introduced into the mixing tank body 1 for mixing and stirring. The drive motor 19 is started to drive the first synchronous wheel 16 to rotate. The synchronous belt 17 drives the first synchronous wheel 16 to rotate, which in turn drives the rotating rod 7 to rotate, driving the stirring rod 8 to rotate and stirring the powder introduced into the mixing tank body 1. At the same time, the rotation of the rotating rod 7 drives the fixed frame 9 to rotate, causing multiple sets of extension rods 10 to drive the rotating plate 11 to perform arc-shaped displacement around the rotating rod 7, effectively stirring the powder. The first air inlet pipe 21 is rotatably connected to the rotating rod 7, and the first air inlet pipe 21 is used to guide the powder into the mixing tank body 1 for mixing and stirring. The air pipe 21 can guide gas into the interior of the rotating rod 7. Through the cavity 12 inside the rotating rod 7, the gas can be guided into the interior of the fixed frame 9. In conjunction with the cavity 12 inside the fixed frame 9, the gas is guided into the interior of the extension rod 10. The gas can be ejected through the conveying groove 13, blowing air into the interior of the mixing tank body 1. When stirring the powder, the powder is lifted up. The two work together to effectively mix the powder. When the rotating rod 7 rotates, it drives the guide fan 14 to rotate. Simultaneously, when the gas is introduced into the rotating rod 7, it is guided into the interior of multiple sets of nozzles 15, generating rising gas at the bottom of the mixing tank body 1. This prevents sedimentation at the bottom of the mixing tank body 1, resulting in more thorough and uniform mixing. It consumes less power and has higher mixing efficiency. Compared with existing mixing devices, this invention improves the overall practicality of the mixing device through its design.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
