Description

Technical Field

[0001] This invention relates to the field of cleaning devices, and more specifically to inclined 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 an inclined powder cleaning device.

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

[0010] An inclined powder cleaning device, comprising:

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

[0012] A tray is inclinedly disposed in the cavity. The tray has a receiving groove. The bottom of the tray is used to connect the cathode of the power supply. The receiving groove is used to place 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 rotating structure for driving the tray to rotate;

[0016] A vacuum pumping device, connected to the cavity, is used to create a negative pressure vacuum state within the cavity.

[0017] The tray in this application can be in various shapes, including but not limited to circles, triangles, etc.

[0018] This application's tilting powder cleaning equipment uses plasma cleaning. The working principle is as follows: the cavity acts as the anode, while the target material (i.e., the powder to be cleaned) and the tray act as the cathode, forming a complete system. The cathode typically uses a resonant power supply for mixing and modulation. By modulating the voltage applied to the object being cleaned (powder), plasma can be generated. 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 tray is tilted within the cavity (the tray's axis is not 90° to the horizontal plane). During operation, the rotating structure allows the tray to rotate around its own axis. This adds the tumbling effect of gravity under the tilt angle to the mechanical tumbling of the powder during cleaning, in addition to the mechanical tumbling of the stirring blades, resulting in a more uniform and thorough cleaning process.

[0019] Compared with traditional chemical cleaning, the method of cleaning powder in this application has shorter operation steps (no need for complicated wastewater treatment), more thorough cleaning, and no problem of low powder recovery rate.

[0020] 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).

[0021] In practical applications, this embodiment is particularly suitable for cleaning powders such as diamond.

[0022] In one embodiment of the present invention, the angle between the axis of the tray and the horizontal plane is A, and the range of A is 10° to 60°.

[0023] If angle A is too small, the tumbling effect is weak; if angle A is too large, the powder tends to accumulate on the lower side, making it easy for the powder to fall out of the container and affecting the reliable stirring of the impeller. When the angle between the axis of the tray and the horizontal plane is 10° to 60°, better powder tumbling and more uniform and thorough cleaning can be achieved.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] In one embodiment of the present invention, a vibration mechanism is installed below the base plate.

[0030] Setting up a vibration mechanism can cause the powder to vibrate, resulting in a more uniform cleaning effect.

[0031] In one embodiment of the present invention, during operation, the rotation direction of the stirring blades is opposite to the rotation direction of the tray.

[0032] This setting allows the powder to tumble better, resulting in more even and thorough cleaning.

[0033] In one embodiment of the present invention, the vacuum pumping device includes a vacuum pump and a molecular pump.

[0034] 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.

[0035] In one embodiment of the present invention, the opening and closing component includes;

[0036] The expansion joint is fixed to the outside of the pipeline, and the expansion rod of the expansion joint extends into the pipeline.

[0037] 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.

[0038] The beneficial effects of this invention are as follows: The inclined 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 tray is inclined within the cavity (the axis of the tray is not 90° to the horizontal plane). During operation, the rotating structure allows the tray to rotate around its own axis. This adds the tumbling of the powder under its own gravity under the influence of the inclined angle, in addition to the mechanical tumbling of the stirring blades during the cleaning process, making the entire cleaning process more uniform and thorough.

[0047] The present invention will now be described in detail with reference to the accompanying drawings.

[0048] Example 1

[0049] like Figure 1 , Figure 2 and Figure 3 As shown, an inclined powder cleaning device includes:

[0050] Cavity 1, cavity 1 is used to connect to the anode of the power supply;

[0051] The tray 2 is inclinedly set inside the cavity 1. The tray 2 has a receiving groove 21. The bottom of the tray 2 is used to connect the cathode of the power supply (which can be a resonant power supply). The receiving groove 21 is used to place the powder 100 to be cleaned. After being powered on, plasma can be generated between the cavity 1 and the tray 2. The generated plasma is used to bombard the powder 100 on the tray 2.

[0052] The stirring blade 3 is rotatably mounted on the tray 2 and is used to stir the powder 100.

[0053] The driving element (omitted in the figure) is used to drive the stirring blade 3 to rotate;

[0054] Rotating structure 4 is used to drive tray 2 to rotate;

[0055] 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.

[0056] The shape of the tray 2 in this application can be in various forms, including but not limited to circles, triangles, etc.

[0057] This application's inclined powder cleaning equipment uses plasma cleaning. The working principle is as follows: the chamber 1 acts as the anode, and the target material (i.e., the powder 100 to be cleaned) and 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 100), plasma can be generated. Utilizing the chemical activity and physical bombardment of the plasma, contaminants on metal surfaces and organic substrates can be effectively removed. In this application, tray 2 is inclined within the chamber 1 (the axis of tray 2 is not 90° to the horizontal plane). During operation, the rotating structure 4 allows tray 2 to rotate around its own axis. This adds the tumbling effect of gravity on the powder 100 under the inclination angle, in addition to the mechanical tumbling of the stirring blades 3, making the entire cleaning process more uniform and thorough. Compared with traditional chemical cleaning, this method of cleaning powder 100 shortens the operation steps (eliminating the need for complex wastewater treatment), achieves more thorough cleaning, and eliminates the problem of low powder 100 recovery rate.

[0058] Compared with traditional chemical cleaning, the method of cleaning powder 100 in this application has shorter operation steps (no need for complicated wastewater treatment), more thorough cleaning, and no problem of low recovery rate of powder 100.

[0059] 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).

[0060] In practical applications, the rotating structure 4 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 pallet has a first gear, the motor's rotating shaft has a second gear, and the motor drives the pallet to rotate through the meshing of the first and second gears).

[0061] In practical applications, this embodiment is particularly suitable for cleaning diamond and other powders 100.

[0062] like Figure 1 As shown, in this embodiment, the angle between the axis of tray 2 and the horizontal plane is A, and the range of A is 10° to 60°.

[0063] If angle A is too small, the tumbling effect is weak; if angle A is too large, powder 100 tends to accumulate in large quantities on the lower side, making it easy for the powder 100 to fall out of the container cavity and affecting the reliable stirring of the stirring blade 3. When the angle between the axis of tray 2 and the horizontal plane is 10° to 60°, the powder 100 can be tumbled better, and the cleaning can be more uniform and thorough.

[0064] like Figure 1As shown, in this embodiment, a lifting structure 6 is also included. The tray 2 is installed on the lifting structure 6, and the lifting structure 6 can drive the tray 2 to move up and down.

[0065] The lifting structure 6 allows for adjustment of the position of the powder tray 2, ensuring proper positioning. Furthermore, it makes loading and unloading the powder 100 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.

[0066] In practical applications, the lifting structure 6 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.

[0067] like Figure 1 and Figure 3 As shown, the tray 2 includes a base plate 22 and side plates 23 located around the base plate 22, the side plates 23 and the base plate 22 forming a receiving groove 21. In this embodiment, the base plate 22 has a circular or polygonal structure, and the side plates 23 are adapted to the base plate 22.

[0068] In practical applications, a vibration mechanism is installed below the base plate 22. The vibration mechanism enables the powder to vibrate 100, resulting in a more uniform cleaning effect.

[0069] In this embodiment, during operation, the rotation direction of the stirring blade 3 is opposite to that of the tray 2. This arrangement allows the powder 100 to tumble better, resulting in more uniform and thorough cleaning.

[0070] In this embodiment, the vacuum pumping device 5 includes a vacuum pump and a molecular pump. For example... Figure 1 As shown, the vacuum port 51 of the vacuum device 5 is connected to the cavity 1 through the pipe 7. The pipe 7 also has an opening and closing component 8 for controlling the opening and closing of the suction port of the vacuum device 5. In this embodiment, the opening and closing component 8 includes:

[0071] The telescopic element 81 is fixed on the outside of the pipe 7, and the telescopic rod 811 of the telescopic element 81 extends into the pipe 7.

[0072] The sealing disc 82 is fixed on the telescopic rod 811 of the telescopic element 81. When the telescopic rod 811 extends, it drives the sealing disc 82 to block the suction port of the vacuum device 5.

[0073] Example 2

[0074] The difference between this embodiment and Embodiment 1 lies in the tray structure. In this embodiment, both the bottom plate and side plates of the tray have fine holes, the outer diameter of which is smaller than the minimum outer diameter of the powder. The fine holes facilitate the removal of the ejected material from the powder and the tray, increasing cleaning efficiency and ensuring cleaning effectiveness.

[0075] 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.
