Description

Technical Field

[0001] This invention relates to the field of cleaning devices, and more specifically to powder cleaning equipment. Background Technology

[0002] Before coating, diamond powder requires pretreatment and cleaning. First, solvent cleaning is performed: solvents (such as alcohols and ketones) are used to clean the diamond powder and remove surface contaminants. Next, ultrasonic cleaning is performed: the diamond powder is placed in a cleaning solution, and ultrasonic vibration generates microbubbles to remove surface contaminants. Then, acid-base cleaning is performed: acid and alkali solutions are used to clean the diamond powder and remove oxides or other impurities. Finally, the cleaned powder is dried. The drying equipment removes volatile substances such as water from the powder at a specific temperature.

[0003] The main drawback is:

[0004] (1) Using acid and alkali to clean the powder makes it difficult to recover the powder and pollutes the environment, which is not conducive to improving production efficiency and pollutes the environment.

[0005] (2) The residual moisture on the surface after cleaning is difficult to completely remove, and blistering is likely to occur after coating, resulting in poor product adhesion and hindering product quality improvement.

[0006] (3) Wastewater treatment generated during the cleaning process is not conducive to reducing costs;

[0007] (4) The strong acids and alkalis used in diamond powder cleaning can harm the human body and are not conducive to safe production. Summary of the Invention

[0008] To address the above-mentioned problems and overcome at least one deficiency, this invention proposes a powder cleaning device.

[0009] The technical solution adopted in this invention is as follows:

[0010] A powder cleaning device, comprising:

[0011] A cavity for connection to the anode of a power source;

[0012] A tray is located inside the cavity. The tray has a receiving groove. The bottom of the tray is used to connect to the cathode of the power supply. The receiving groove is used to hold the powder to be cleaned. When the power is turned on, plasma can be generated between the cavity and the tray. The generated plasma is used to bombard the powder on the tray.

[0013] A stirring blade is rotatably mounted on the tray for stirring powder;

[0014] A driving element for driving the stirring blades to rotate;

[0015] A vacuum pumping device, connected to the cavity, is used to create a negative pressure vacuum state within the cavity.

[0016] The tray in this application can be in various shapes, including but not limited to circles, triangles, etc.

[0017] The powder cleaning equipment of this application uses plasma cleaning. Its working principle is as follows: the cavity acts as the anode, and the target material (i.e., the powder to be cleaned) and the tray act as the cathode, forming a complete system. The cathode is typically mixed and modulated using a resonant power supply. By modulating the voltage applied to the object to be cleaned (powder), plasma can be generated. By utilizing the chemical activity and physical bombardment of the plasma, contaminants on metal surfaces and organic substrates can be effectively removed. In this application, the powder on the tray is continuously agitated by the stirring blades, ensuring uniform cleaning and a cleaner surface. Compared with traditional chemical cleaning, the operation steps are shortened (no complicated wastewater treatment is required), the cleaning is more thorough, and there is no problem of low powder recovery rate.

[0018] In practical applications, the driving element can be a motor or a rotary cylinder, etc. The driving element can drive directly or indirectly (for example, through conventional transmission structures such as gear sets or worm gears).

[0019] In practical applications, this embodiment is particularly suitable for cleaning powders such as diamond.

[0020] In one embodiment of the present invention, a lifting structure is further included, wherein the tray is mounted on the lifting structure and the lifting structure can drive the tray to move up and down.

[0021] The lifting mechanism allows for adjustment of the powder tray's position, ensuring proper placement. Furthermore, it makes loading and unloading powder from the tray more convenient and efficient; additionally, it facilitates internal maintenance and cleaning, such as tray replacement and residue removal.

[0022] In practical applications, the lifting structure can take many forms, including but not limited to: electric push rods, cylinders or hydraulic cylinders, as well as gear and rack structures, transmission belt structures or transmission chains, etc.

[0023] In one embodiment of the present invention, a rotating structure for driving the tray to rotate is also included, wherein during operation, the rotation direction of the stirring blade is opposite to the rotation direction of the tray.

[0024] In practical applications, the rotating structure can be a single-axis center drive (such as direct motor drive) or a side drive to rotate the main shaft (such as a first gear on the tray and a second gear on the rotating shaft of the motor, with the motor driving the tray to rotate through the meshing of the first and second gears).

[0025] In one embodiment of the present invention, the tray includes a bottom plate and side plates located around the periphery of the bottom plate, the side plates and the bottom plate forming the receiving groove.

[0026] In one embodiment of the present invention, the base plate is a circular or polygonal structure, and the side plate is adapted to the base plate.

[0027] In one embodiment of the present invention, a vibration mechanism is installed below the base plate.

[0028] Setting up a vibration mechanism can cause the powder to vibrate, resulting in a more uniform cleaning effect.

[0029] In one embodiment of the present invention, the vibration mechanism is a mechanical vibration device or an ultrasonic vibration device.

[0030] In one embodiment of the present invention, the vacuum pumping device includes a vacuum pump and a molecular pump.

[0031] In one embodiment of the present invention, the vacuum port of the vacuum pumping device is connected to the cavity through a pipeline, and the pipeline is also provided with an opening and closing component for controlling the opening and closing of the suction port of the vacuum pumping device.

[0032] In one embodiment of the present invention, the opening and closing component includes;

[0033] The expansion joint is fixed to the outside of the pipeline, and the expansion rod of the expansion joint extends into the pipeline.

[0034] The sealing disc is fixed on the telescopic rod of the telescopic element. When the telescopic rod extends, it causes the sealing disc to block the suction port of the vacuum device.

[0035] The beneficial effects of this invention are as follows: The powder cleaning equipment of this application uses plasma for cleaning. The working principle is as follows: the cavity acts as the anode, and the target material (i.e., the powder to be cleaned) and the tray act as the cathode, forming a complete system. The cathode is typically mixed and modulated using a resonant power supply. By modulating the voltage applied to the object to be cleaned (powder), plasma can be generated. By utilizing the chemical activity and physical bombardment of the plasma, contaminants on metal surfaces and organic substrates can be effectively removed. In this application, the powder on the tray is continuously agitated by the stirring blades, ensuring uniform cleaning and a cleaner surface. Compared with traditional chemical cleaning, the operation steps are shortened (no complicated wastewater treatment is required), the cleaning is more thorough, and there is no problem of low powder recovery rate.

[0045] The present invention will now be described in detail with reference to the accompanying drawings.

[0046] Example 1

[0047] like Figure 1 , Figure 2 and Figure 3As shown, a powder cleaning device includes:

[0048] Cavity 1, cavity 1 is used to connect to the anode of the power supply;

[0049] Tray 2, located inside cavity 1, has a receiving groove 21. The bottom of tray 2 is used to connect the cathode of the power supply (usually a resonant power supply). The receiving groove 21 is used to place the powder 3 to be cleaned. After power is applied, plasma can be generated between cavity 1 and tray 2. The generated plasma is used to bombard the powder 3 on tray 2.

[0050] The stirring blade 4 is rotatably mounted on the tray 2 and is used to stir the powder 3. (See attached image) Figure 2 ;

[0051] A driving element (not shown in the figure) is used to drive the stirring blade 4 to rotate;

[0052] The vacuum pumping device 5 is connected to the cavity 1 and is used to create a negative pressure vacuum state inside the cavity 1.

[0053] The shape of the tray 2 in this application can be in various forms, including but not limited to circles, triangles, etc.

[0054] The powder cleaning equipment of this application uses plasma cleaning. Its working principle is as follows: the chamber 1 acts as the anode, and the target material (i.e., the powder 3 to be cleaned) and the tray 2 act as the cathode, forming a complete system. The cathode is typically mixed and modulated using a resonant power supply. By modulating the voltage applied to the object to be cleaned (powder 3), plasma can be generated. By utilizing the chemical activity and physical bombardment of the plasma, contaminants on metal surfaces and organic substrates can be effectively removed. In this application, the powder 3 on the tray 2 is continuously agitated by the stirring blades 4, ensuring uniform cleaning and a cleaner surface. Compared with traditional chemical cleaning, the operation steps are shortened (no complicated wastewater treatment is required), the cleaning is more thorough, and there is no issue of low powder recovery rate.

[0055] In practical applications, the driving element can be a motor or a rotary cylinder, etc. The driving element can drive directly or indirectly (for example, through conventional transmission structures such as gear sets or worm gears).

[0056] In practical applications, this embodiment is particularly suitable for cleaning powders such as diamond.

[0057] like Figure 1 As shown, in this embodiment, a lifting structure 8 is also included. The tray 2 is installed on the lifting structure 8, and the lifting structure 8 can drive the tray 2 to move up and down.

[0058] The lifting structure 8 allows for adjustment of the position of the powder tray 2, ensuring proper positioning. Furthermore, it makes loading and unloading the powder 3 from the tray 2 more convenient and efficient; additionally, it facilitates internal maintenance and cleaning of the equipment, such as replacing the tray 2 and removing residues.

[0059] In practical applications, the lifting structure 8 can take many forms, including but not limited to: electric push rod, cylinder or hydraulic cylinder, as well as gear and rack structure, transmission belt structure or transmission chain structure, etc.

[0060] like Figure 1 As shown, in this embodiment, a rotating structure 6 for driving the tray 2 to rotate is also included. During operation, the rotation direction of the stirring blade 4 is opposite to the rotation direction of the tray 2.

[0061] In practical applications, the rotating structure 6 can be a single-axis center drive (e.g., directly driven by a motor) or a side drive that drives the main shaft to rotate (e.g., the tray 2 has a first gear, the motor's rotating shaft has a second gear, and the motor drives the tray 2 to rotate through the meshing of the first and second gears).

[0062] like Figure 1 and Figure 2 As shown, the tray 2 includes a base plate 22a and side plates 22b located around the periphery of the base plate 22a. The side plates 22b and the base plate 22a form a receiving groove 21. In this embodiment, the base plate 22a has a circular or polygonal structure, and the side plates 22b are adapted to the base plate 22a.

[0063] In practical applications, a vibration mechanism can be installed below the base plate 22a. The vibration mechanism allows the powder 3 to vibrate, resulting in a more uniform cleaning effect. The vibration mechanism can be a mechanical vibration device or an ultrasonic vibration device.

[0064] In this embodiment, the vacuum pumping device 5 includes a vacuum pump and a molecular pump.

[0065] like Figure 1 As shown, the vacuum port 51 of the vacuum pumping device 5 is connected to the cavity 1 via a pipe 71, and the pipe 71 also has an opening and closing assembly 72 for controlling the opening and closing of the suction port of the vacuum pumping device 5. In this embodiment, the opening and closing assembly 72 includes;

[0066] The telescopic element 721 is fixed on the outside of the pipe 71, and the telescopic rod 7211 of the telescopic element 721 extends into the pipe 71.

[0067] The sealing disc 722 is fixed on the telescopic rod 7211 of the telescopic element 721. When the telescopic rod 7211 extends, it drives the sealing disc 722 to block the suction port of the vacuum device 5.

[0068] Example 2

[0069] like Figure 4 As shown, the difference between this embodiment and Embodiment 1 lies in the structure of the tray 2. In this embodiment, both the bottom plate 22a and the side plate 22b of the tray 2 have fine holes 221, and the outer diameter of the fine holes 221 is smaller than the minimum outer diameter of the powder 3. The fine holes 221 make it easier for the bombarded material to detach from the powder 3 and the tray 2, thereby increasing the cleaning efficiency.

[0070] like Figure 4 As shown in this embodiment, the upper surface of the side plate 22b has centrifugal blades 9 extending horizontally away from the mounting groove. The centrifugal blades 9 are used to push the gas or impurities generated by the plasma impact outward, thereby increasing the cleaning efficiency and ensuring the cleaning effect.

[0071] In other embodiments, a heating element may also be provided to heat the powder 3 in the tray 2. In actual use, the heating element can heat the tray 2 in a contact manner to heat the powder 3. In addition, the heating element can also heat the powder 3 in a non-contact manner such as radiation.

[0072] The above description is merely a preferred embodiment of the present invention and does not limit the scope of patent protection of the present invention. Any equivalent structural transformations made based on the description and drawings of the present invention, whether directly or indirectly applied to other related technical fields, are similarly included within the scope of protection of the present invention.
