Description

Technical Field

[0001] This utility model relates to the field of powder mixing technology, specifically to a powder mixing device for preparing metal ceramics. Background Technology

[0002] In the preparation of cermets, since the metal phase and ceramic phase often differ greatly in density, particle size, shape and chemical properties, a special powder mixing device is required to achieve highly uniform mixing and avoid segregation or contamination.

[0003] A search of Chinese patent CN210496217U reveals a powder mixing device for preparing metal-ceramic materials. A second mixing chamber is located at the lower middle of the first mixing chamber and is welded to it. Two feed funnels are installed through the upper end of the first mixing chamber, and a fixing frame is fixedly connected inside the first mixing chamber by screws. A motor is fixedly connected to the middle of the fixing frame by screws. Metal powder and ceramic powder are separately loaded into the feed funnels, allowing them to flow into the first mixing chamber from the feed funnels. The motor drives a rectangular plate to rotate, initially mixing the metal and ceramic powders flowing from the feed funnels. Then, a stirring plate further mixes the metal and ceramic powders falling into the second mixing chamber. This patent solves the problem of difficulty in uniformly mixing large quantities of metal and ceramic powders.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. During the mixing process of metal ceramic powder, the mixing equipment is easily subject to electrostatic adsorption. This causes the powder particles to be charged by static charge generated by intense friction during the mixing process and adsorbed onto the mixing equipment. At the same time, it makes the powder flowability worse and the mixing uneven. When cleaning the mixing device, it is not convenient to clean the corners of the inner wall of the mixing device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a powder mixing device for preparing metal ceramics.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides a powder mixing device for preparing metal ceramics, including a tank body, two inlet pipes fixedly installed on the tank body, an electromagnetic valve provided at the bottom of the tank body, a drive mechanism provided on the tank body, a conveying mechanism provided between the tank body and the drive mechanism, and a rotating mechanism provided between the drive mechanism and the conveying mechanism.

[0008] The rotating mechanism includes a shaft block disposed on the conveying mechanism, a transmission rod rotatably mounted on the shaft block, a plurality of fixed frames fixedly mounted on the transmission rod, a stirring frame rotatably mounted on each fixed frame, and two torsion springs connecting the fixed frame and the stirring frame.

[0009] The conveying mechanism includes a support assembly mounted on the tank body, and the support assembly is provided with multiple conveying pipes, each of which is provided with multiple pressure valves.

[0010] Furthermore, the drive mechanism includes two symmetrically fixed mounting plates on the tank body, and a drive motor is provided between the two mounting plates.

[0011] Furthermore, a first pulley is fixedly installed on the output end of the drive motor, a second pulley is fixedly installed on the transmission rod, and a belt body is movably installed between the first pulley and the second pulley.

[0012] Furthermore, the support assembly includes a rotating shell rotatably mounted on the tank body, the rotating shell being fixed to a shaft block, and a shell cover fixed to the tank body being rotatably mounted on the rotating shell.

[0013] Furthermore, two connecting pipes are symmetrically fixedly installed on the shell cover, and an interface is fixedly installed between the two connecting pipes.

[0014] Furthermore, a gear ring is fixedly installed on the rotating shell, and a gear that meshes with the gear ring is fixedly installed on the first pulley.

[0015] The above-described solution of this utility model has at least the following beneficial effects:

[0016] 1. In this utility model, the drive motor is controlled to operate, causing the output end of the drive motor to drive the first pulley to rotate. The first pulley drives the second pulley to rotate through the belt body. The second pulley drives the fixed frame to rotate through the transmission rod. The fixed frame, together with the stirring frame, mixes the powder conveyed in the tank. The stirring frame, supported by the elastic force of the torsion spring, abuts against the conveying pipe, causing the stirring frame to rotate around the fixed frame. When the stirring frame separates from the conveying pipe, the torsion spring uses its elastic force to drive the stirring frame to rotate and reset. The vibration generated during the reset can shake off the adsorbed powder. At the same time, the vibration can improve the flowability of the powder, making the powder mix more uniform.

[0017] 2. In this utility model, water is transported to the inside of the conveying pipe through the interface, connecting pipe and rotating shell by controlling the external water conveying equipment. When the pressure inside the conveying pipe reaches a certain level, the pressure valve opens, causing the water inside the conveying pipe to spray out and rinse the tank. The rotation of the first pulley can drive the gear to rotate, and the gear can drive the gear ring to rotate through meshing. The gear ring can drive the conveying pipe to rotate through the rotating shell, thereby improving the rinsing capacity of the conveying pipe. The conveying pipe can rinse the corners inside the tank. Attached Figure Description

Detailed Implementation

[0025] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0026] like Figures 1 to 5As shown, an embodiment of this utility model provides a powder mixing device for preparing metal ceramics, including a tank 1, two inlet pipes 2 fixedly installed on the tank 1, an electromagnetic valve 3 fixedly installed at the bottom of the tank 1, a drive mechanism on the tank 1, a conveying mechanism shared between the tank 1 and the drive mechanism, and a rotating mechanism shared between the drive mechanism and the conveying mechanism. The rotating mechanism includes a shaft block 13 mounted on the conveying mechanism, a transmission rod 14 rotatably mounted on the shaft block 13, multiple fixed frames 17 fixedly mounted on the transmission rod 14, a stirring frame 18 rotatably mounted on each fixed frame 17, and two torsion springs 19 connected between the fixed frames 17 and the stirring frame 18. The drive mechanism includes two symmetrically fixedly mounted frame plates 4 on the tank 1, a drive motor 5 fixedly mounted between the two frame plates 4, a first pulley 6 fixedly mounted on the output end of the drive motor 5, a second pulley 15 fixedly mounted on the transmission rod 14, and a belt body 16 movably mounted between the first pulley 6 and the second pulley 15.

[0027] In this embodiment of the invention, two inlet pipes 2 are respectively connected to an external metal powder conveying device and an external ceramic powder conveying device. The solenoid valve 3 is connected to an external downstream processing device. The operator controls the drive motor 5 to operate, causing the output of the drive motor 5 to drive the first pulley 6 to rotate. The first pulley 6, through the belt body 16, drives the second pulley 15 to rotate. The second pulley 15, through the transmission rod 14, drives the fixed frame 17 to rotate, thus controlling the external metal powder conveying device to transport the metal powder to the inside of the tank 1. The external conveying ceramic powder equipment conveys ceramic powder to the inside of the tank 1, so that the fixed frame 17 and the stirring frame 18 work together to mix the powder conveyed in the tank 1. The stirring frame 18 is supported by the elastic force of the torsion spring 19 and abuts against the conveying pipe 20, so that the stirring frame 18 rotates around the fixed frame 17. When the stirring frame 18 separates from the conveying pipe 20, the torsion spring 19 can drive the stirring frame 18 to rotate and reset using its elastic force. The vibration generated by the reset can shake off the adsorbed powder. At the same time, the vibration can improve the flowability of the powder and make the powder mix more uniform.

[0028] After mixing is complete, control solenoid valve 3 to open, allowing the mixed powder to be transported to external subsequent processing equipment.

[0029] Figures 1 to 5As shown, the conveying mechanism includes a support assembly mounted on the tank body 1. The support assembly is provided with multiple conveying pipes 20, and each conveying pipe 20 is provided with multiple pressure valves 21. The support assembly includes a rotating shell 7 rotatably mounted on the tank body 1. The rotating shell 7 is fixed to the shaft block 13. A shell cover 8 fixed to the tank body 1 is rotatably mounted on the rotating shell 7. Two connecting pipes 9 are symmetrically fixedly mounted on the shell cover 8. An interface 10 is fixedly mounted between the two connecting pipes 9. A gear ring 11 is fixedly mounted on the rotating shell 7. A gear 12 that meshes with the gear ring 11 is fixedly mounted on the first pulley 6.

[0030] In this embodiment of the utility model, interface 10 is connected to an external water conveying device. The operator controls the external water conveying device to deliver water through interface 10, connecting pipe 9 and rotating shell 7 to the inside of conveying pipe 20. When the pressure inside conveying pipe 20 reaches a certain level, pressure valve 21 opens, causing the water inside conveying pipe 20 to spray out and rinse the inside of tank 1. The rotation of the first pulley 6 can drive the gear 12 to rotate, and the gear 12 drives the gear ring 11 to rotate through meshing. The gear ring 11 drives the conveying pipe 20 to rotate through rotating shell 7, thereby improving the rinsing capacity of conveying pipe 20. The conveying pipe 20 can rinse the corners inside tank 1.

[0031] After rinsing, the staff controlled the inner wall of tank 1 to heat and dry it, so that the inside of tank 1 was dry.

[0032] Working principle: The operator controls the drive motor 5 to operate, causing the output of the drive motor 5 to drive the first pulley 6 to rotate. The first pulley 6 drives the second pulley 15 to rotate via the belt body 16. The second pulley 15 drives the fixed frame 17 to rotate via the transmission rod 14. The operator controls the external conveying equipment for metal powder to transport metal powder to the inside of the tank 1, and controls the external conveying equipment for ceramic powder to transport ceramic powder to the inside of the tank 1. The fixed frame 17, in conjunction with the stirring frame 18, mixes the powders conveyed in the tank 1. The stirring frame 18, supported by the elastic force of the torsion spring 19, abuts against the conveying pipe 20, causing the stirring frame 18 to rotate around the fixed frame 17. When the stirring frame 18 separates from the conveying pipe 20, the torsion spring 19 uses its elastic force to drive the stirring frame 18 to rotate and reset. The vibration generated during the reset can shake off the adsorbed powder. At the same time, the vibration can improve the flowability of the powder and make the powder mix more uniform. After the mixing is completed, the operator controls the solenoid valve 3 to open, allowing the mixed powder to be conveyed to the external subsequent processing equipment.

[0033] When it is necessary to flush the inside of tank 1, the solenoid valve 3 is connected to the wastewater loading equipment. By controlling the external water conveying equipment, water is transported through interface 10, connecting pipe 9 and rotating shell 7 to the inside of the conveying pipe 20. When the pressure inside the conveying pipe 20 reaches a certain level, the pressure valve 21 opens, causing the water in the conveying pipe 20 to spray out and flush the inside of tank 1. The rotation of the first pulley 6 can drive the gear 12 to rotate, and the gear 12 drives the gear ring 11 to rotate through meshing. The gear ring 11 drives the conveying pipe 20 to rotate through the rotating shell 7. The conveying pipe 20 can flush the corners inside tank 1. The flushed wastewater flows into the wastewater loading equipment through the solenoid valve 3.

[0034] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
