Description

Technical Field

[0001] The present application relates to the technical field of graphene powder cleaning equipment, and in particular to a mixed powder cleaning equipment. Background Art

[0002] During the chemical vapor deposition (CVD) growth process of graphene mixed with other powders (such as graphene metal composite powder), powder agglomeration is prone to occur. In order to avoid agglomeration, an inhibitor powder that inhibits agglomeration needs to be added. After CVD is completed, the remaining graphene metal composite powder needs to be cleaned with a cleaning solution so that the mixed inhibitor powder is dissolved in the cleaning solution and removed, thereby achieving the purpose of recycling the graphene metal composite powder.

[0003] At present, cleaning is generally carried out by manual stirring. The amount of water added, cleaning time and stirring time during the cleaning process are manually controlled to ensure that the mixed powder and the cleaning liquid are fully mixed and the inhibitor powder is fully dissolved in the cleaning liquid. However, this method is not suitable for large-scale cleaning. It is difficult to control the cleaning process and to ensure that the inhibitor powder is fully dissolved. Therefore, the existing technology has problems such as low cleaning efficiency due to water and labor waste, poor cleaning quality, and low quality of recovered graphene metal composite powder. Summary of the invention

DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0044] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0045] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0046] During the chemical vapor deposition (CVD) process of graphene mixed with other powders (such as graphene metal composite powder), powder agglomeration is prone to occur. In order to avoid agglomeration, an inhibitor powder that inhibits agglomeration needs to be added. After the CVD is completed, the remaining graphene metal composite powder needs to be cleaned with a cleaning solution so that the mixed inhibitor powder is dissolved in the cleaning solution and removed, thereby achieving the purpose of recycling the graphene metal composite powder.

[0047] At present, cleaning is generally carried out by manual stirring. The amount of water added, the cleaning time and the stirring time during the cleaning process are manually controlled so that the mixed powder is fully mixed with the cleaning liquid and the inhibitor powder is fully dissolved in the cleaning liquid. When the amount of water added is too little, the inhibitor powder cannot be fully dissolved. When the amount of water added is too much, the subsequent water removal work time will be increased, and water resources will be wasted, increasing the recycling cost. When the cleaning time and stirring time are too short, it is difficult for the mixed powder to be fully mixed with water, and the inhibitor powder is difficult to fully dissolve; when the cleaning time and stirring time are too long, the graphene metal composite powder may be damaged, affecting the recycling quality.

[0048] The existing manual stirring and cleaning method is not suitable for large-scale cleaning. It is difficult to control the cleaning process and ensure that the inhibitor powder is fully dissolved, resulting in low cleaning efficiency. In the prior art, there is also a method of replacing manual stirring with mechanical stirring, but it is still difficult to ensure that the inhibitor powder is fully dissolved while ensuring that the graphene metal composite powder is not damaged, and the cleaning efficiency is still low.

[0049] Based on this, an embodiment of the present application provides a mixed powder cleaning device for removing inhibitor powder from graphene metal composite powder. The mixed powder cleaning device includes a cleaning barrel, a liquid supply device, a clamping and fixing device, a cleaning device and an ultrasonic transducer. The cleaning barrel is provided to contain the mixed powder, an appropriate amount of water is added to the mixed powder through the liquid supply device, and the cleaning barrel is fixed by the clamping and fixing device so that the cleaning device stirs the mixed powder and water in the cleaning barrel to mix them fully, and then emits ultrasonic waves through the ultrasonic transducer, and converts the sound energy into mechanical vibration and transmits it to the cleaning barrel, so that the bubbles in the cleaning barrel maintain high-frequency vibration, thereby destroying the adsorption force between the inhibitor powder and the graphene metal composite powder, so that the inhibitor powder is separated and dissolved in water.

[0050] The mixed powder cleaning equipment provided in the embodiment of the present application stirs and applies ultrasound at the same time. The stirring makes the mixed powder and water fully mixed, which is conducive to the full dispersion of the mixed powder in the water. At the same time, the stirring is conducive to the generation of a large number of microbubbles. A large number of microbubbles maintain high-frequency vibration under the action of ultrasound, which accelerates the separation of the inhibitor powder and the graphene metal composite powder, thereby shortening the stirring time and the cleaning time. Therefore, through the cooperation of the cleaning barrel, the liquid supply device, the clamping and fixing device, the cleaning device and the ultrasonic transducer, not only can automatic water addition and stirring be achieved, but also the cleaning time and the stirring time can be shortened, thereby achieving sufficient water addition without wasting water resources, and the inhibitor powder is quickly and fully dissolved without damaging the graphene metal composite powder, thereby ensuring a high recovery quality and greatly improving the cleaning efficiency.

[0051] It should be noted that the mixed powder cleaning device provided in the embodiment of the present application is not only suitable for cleaning graphene metal composite powders, but also suitable for cleaning other types of mixed powders, and water can be replaced by other types of cleaning liquids. Specifically, the mixed powder includes powder to be recycled (such as graphene metal composite powder) and target powder (such as inhibitor powder), the target powder can be dissolved in the cleaning liquid, and the powder to be recycled is insoluble or difficult to dissolve in the cleaning liquid.

[0052] like Figure 1 As shown, the mixed powder cleaning device includes a base 1, a cleaning bucket 3, a liquid supply device 4, a clamping device 2, a cleaning device 5 and an ultrasonic transducer 8 (the ultrasonic transducer 8 is located inside the clamping device 2, Figure 1 Not shown, Figure 2 The partial structure of the clamping fixture 2 is hidden in the figure to show the setting position of the ultrasonic transducer 8).

[0053] The base 1 is a structure for installing the cleaning bucket 3, the liquid supply device 4, the clamping and fixing device 2, the cleaning device 5 and the ultrasonic transducer 8, so that each device is integrated into one.

[0054] The clamping and fixing device 2 is arranged on the base 1 , and the clamping and fixing device 2 is a mechanism for fixing the cleaning bucket 3 so that the cleaning bucket 3 can remain stable and withstand the vibration of stirring and ultrasonic waves.

[0055] Combination Figure 1 and Figure 2 As shown, the clamping and fixing device 2 includes a box body 21 and a plurality of clamping mechanisms 22. The box body 21 is fixedly arranged on the base 1, and the box body 21 is provided with a first cavity 211 and a second cavity 212. The first cavity 211 is used to accommodate the cleaning bucket 3, and the second cavity 212 is used to accommodate the ultrasonic transducer 8. The plurality of clamping mechanisms 22 are arranged at intervals around the circumference of the first cavity 211 to clamp and fix the cleaning bucket 3. Figure 2 Part of the clamping mechanism 22 is hidden in order to facilitate observation of the remaining structure. It can be understood that Figure 2 Four clamping mechanisms 22 are shown in the figure. The four clamping mechanisms 22 are arranged around the first cavity 211 at intervals, and cooperate in groups of two to clamp the cleaning bucket 3.

[0056] Specifically, the box body 21 includes an outer wall 213, a top wall 215 and a partition wall 214. The partition wall 214 encloses a first cavity 211. The outer wall 213 is spaced apart on the periphery of the partition wall 214. A second cavity 212 is formed between the outer wall 213 and the partition wall 214. The bottoms of the outer wall 213 and the partition wall 214 are connected to the base 1. The top wall 215 covers the tops of the outer wall 213 and the partition wall 214, and the top wall 215 is provided with an opening, which is connected to the first cavity 211 for the cleaning bucket 3 to enter and exit.

[0057] In some embodiments, at least part of the barrel wall of the washing barrel 3 abuts against the partition wall 214, and the high-frequency vibration emitted by the ultrasonic transducer 8 is transmitted to the washing barrel 3 through the partition wall 214. Optionally, the shape of the washing barrel 3 is adapted to the partition wall 214, and the washing barrel 3 abuts against the partition wall 214 in the circumferential direction.

[0058] In other embodiments, there is a gap between the cleaning bucket 3 and the partition wall 214, and the gap is used to accommodate a conductive liquid (such as water or cleaning liquid, or any liquid that can conduct sound wave vibrations), so that the ultrasonic transducer 8 transmits ultrasonic waves to the cleaning bucket 3 through the partition wall 214 and the conductive liquid, ensuring that the ultrasonic waves act on the cleaning bucket 3 from all directions, thereby ensuring that the cleaning bucket 3 is fully and evenly vibrated, while avoiding the ultrasonic energy from escaping from the gap. Optionally, the outer diameter of the cleaning bucket 3 is smaller than the inner diameter of the first cavity 211, so that there is a gap between the entire outer circumference of the cleaning bucket 3 and the partition wall 214, so that the ultrasonic waves are all transmitted to the conductive liquid through the partition wall 214, and then transmitted to the cleaning bucket 3 through the conductive liquid, so that the ultrasonic vibrations received by the cleaning bucket 3 are more uniform.

[0059] The plurality of clamping mechanisms 22 can be installed on the base 1 or the box 21 around the first cavity 211, as long as they are arranged at intervals around the circumference of the first cavity 211 so as to be able to clamp and fix the cleaning bucket 3. Figure 2 As shown, a plurality of clamping mechanisms 22 are mounted on the top wall 215 of the box body 21 .

[0060] There are various structures of the clamping mechanism 22, as long as it can be pressed against the cleaning bucket 3. For example, the clamping mechanism 22 includes a fixed seat 221, a pressing block 222, a handle 223, a sliding rod 224 and a self-locking connecting rod 225. The fixed seat 221 is fixed to the box body 21, the sliding rod 224 is slidably penetrated in the fixed seat 221, the pressing block 222 is arranged at one end of the sliding rod 224 close to the first cavity 211, the handle 223 is rotatably arranged at one end of the sliding rod 224 away from the first cavity 211, and the self-locking connecting rod 225 is connected between the handle 223 and the fixed seat 221. Rotating the handle 223 drives the sliding rod 224 to slide toward the cleaning bucket 3 and press against the outer wall of the cleaning bucket 3 through the pressing block 222, and makes the self-locking connecting rod 225 reach a self-locking state, thereby locking the handle 223 and the sliding rod 224, so that the pressing block 222 remains pressed against the outer wall of the cleaning bucket 3. The plurality of clamping mechanisms 22 cooperate to clamp the cleaning bucket 3 and ensure the stability of the cleaning bucket 3 .

[0061] The liquid supply device 4 is a structure for inputting cleaning liquid into the cleaning bucket 3. In some embodiments, the liquid supply device 4 includes a liquid storage device and an island valve, the liquid storage device is used to store the cleaning liquid, the liquid storage device is connected to the island valve through a pipeline, the island valve transports the cleaning liquid to the cleaning bucket 3 through another pipeline, and the amount of liquid input into the cleaning bucket 3 is controlled by the island valve.

[0062] The cleaning device 5 includes a stirring mechanism 51, which is used to stir the mixed powder and the cleaning liquid to prevent the mixed powder from sinking to the bottom and ensure that the mixed powder and the cleaning liquid are fully mixed. On the one hand, it can promote the target powder to fully contact and dissolve with the cleaning liquid, and on the other hand, it can form a large number of microbubbles in the cleaning liquid through stirring.

[0063] The cleaning device 5 is arranged on the base 1 through a movable mechanism, so that the stirring mechanism 51 can enter the cleaning bucket 3 to perform stirring work, and can also leave and avoid the cleaning bucket 3 to facilitate installation or removal of the cleaning bucket 3.

[0064] Combination Figure 1 , Figure 3 and Figure 4 As shown, the mixed powder cleaning equipment also includes a lifting device 6, which includes a first vertical guide rail 61, a first vertical slider 62 and a first vertical driving mechanism 63. The first vertical slider 62 is movably arranged on the first vertical guide rail 61, and the cleaning device 5 is connected to the first vertical slider 62. The output end of the first vertical driving mechanism 63 is connected to the first vertical slider 62 to drive the cleaning device 5 to rise and fall, thereby making the stirring mechanism 51 enter and exit the cleaning barrel 3.

[0065] The first vertical drive mechanism 63 can be selected from a variety of drive structures, such as a motor screw nut mechanism, a telescopic electric cylinder mechanism, etc. In some embodiments, the first vertical drive mechanism 63 is a motor screw nut mechanism, the motor is fixedly mounted on the first vertical guide rail 61, the nut is connected to the output end of the motor through a screw, and the nut is fixedly connected to the first vertical slider 62. When the motor drives the screw to rotate, the nut rises and falls, thereby driving the first vertical slider 62 to rise and fall.

[0066] In some embodiments, in combination Figure 1 , Figure 3 and Figure 4 As shown, the mixed powder cleaning device also includes a transverse moving device 7, which includes a transverse guide rail 71, a transverse slider 72 and a transverse driving mechanism 73. The transverse guide rail 71 is fixedly arranged on the base 1, the transverse slider 72 is movably arranged on the transverse guide rail 71, the first vertical guide rail 61 is connected to the transverse slider 72, and the output end of the transverse driving mechanism 73 is connected to the transverse slider 72. When the transverse driving mechanism 73 is working, it drives the transverse slider 72 to move along the transverse guide rail 71, thereby driving the first vertical guide rail 61, the first vertical slider 62 and the cleaning device 5 to move transversely as a whole, so that the cleaning device 5 is located above the clamping and fixing device 2 to be close to the cleaning bucket 3, or the cleaning device 5 is moved away from the clamping and fixing device 2 to avoid the cleaning bucket 3.

[0067] The transverse driving mechanism 73 can be selected from a variety of driving structures, such as a motor screw nut mechanism, a telescopic electric cylinder mechanism, etc. In some embodiments, the transverse driving mechanism 73 is a motor screw nut mechanism, the motor is fixedly mounted on the transverse guide rail 71, the nut is connected to the output end of the motor through a screw, and the nut is fixedly connected to the transverse slider 72. When the motor drives the screw to rotate, the nut moves transversely, thereby driving the transverse slider 72 to move transversely.

[0068] Figure 5 The structure of the stirring mechanism 51 is shown. The stirring mechanism 51 includes a rotary drive motor 511, a rotating shaft 512, blades and a flushing nozzle 514. The rotary drive motor 511 is connected to one end of the rotating shaft 512, the blades are connected to the other end of the rotating shaft 512, and the flushing nozzle 514 is connected to the liquid supply device 4. The water outlet direction of the flushing nozzle 514 is toward the blades.

[0069] The stirring mechanism 51 can not only fully stir the mixed liquid and powder during cleaning, but also can rinse the substances attached to the blades through the flushing nozzle 514 after cleaning, so as to achieve the effect of self-cleaning, facilitate the next cleaning, and further achieve fully automated cleaning. Exemplarily, the flushing nozzle 514 has a plurality of liquid outlets, and the plurality of liquid outlets are arranged at intervals along the length direction of the blade (i.e., along the radial direction of the rotating shaft 512), so that the cleaning liquid sprayed from the plurality of liquid outlets can cover the blade, ensuring full flushing. Optionally, the position of the flushing nozzle 514 is higher than the position of the blade, and the water outlet direction of the flushing nozzle 514 is inclined from top to bottom and toward the direction of the rotating shaft 512, so that the flushing nozzle 514 avoids the blade to avoid interfering with the rotation of the blade, and the water outlet direction of the flushing nozzle 514 is set at an angle to the surface of the blade, thereby increasing the impact on the surface of the blade.

[0070] It should be noted that the cleaning liquid used to dissolve the target powder and the cleaning liquid used to rinse the blades may be of the same type or different types.

[0071] In other words, the liquid supply device 4 may include a plurality of liquid storages, each of which stores cleaning liquids with different functions, and in addition to storing cleaning liquids for dissolving the target powder, cleaning liquids for washing the blades may also be stored. For example, when the target powder is easily soluble in oil, the cleaning liquid for dissolving the target powder is the corresponding oil; and the cleaning liquid for washing the blades may be a liquid that can dissolve oil to prevent the powder and oil from adhering to the blades.

[0072] like Figure 5 As shown, the blades include vertical comb blades 5131 and transverse blades 5132 .

[0073] The vertical comb blades 5131 are relatively long in height direction, and can fully stir from near the liquid surface to near the bottom of the barrel, ensuring that the cleaning liquid and the mixed powder are evenly mixed, so that each depth position has uniform and more microbubbles.

[0074] The transverse blade 5132 is installed at one end of the rotating shaft 512 close to the bottom of the barrel. The transverse blade 5132 stirs the liquid at the bottom of the barrel, thereby driving the liquid flow in the entire cleaning barrel 3, so as to achieve uniform mixing of the cleaning liquid and the mixed powder. In comparison, under the same rotation speed, the force output by the transverse blade 5132 is smaller, which can reduce the damage to the powder to be recovered while ensuring sufficient stirring and mixing.

[0075] The vertical comb blades 5131 and the horizontal blades 5132 are replaceably mounted on the rotating shaft 512. For example, in the early stage of the cleaning process, the vertical comb blades 5131 are used to fully stir the liquids at different depths and generate a large number of bubbles; in the later stage of the cleaning process, the horizontal blades 5132 are used to stir at the bottom of the barrel, so that the mixed powder and the cleaning liquid are kept mixed and do not sink to the bottom, and the microbubbles are kept continuously generated and evenly distributed.

[0076] In some embodiments, Figure 4 As shown, the cleaning device 5 also includes a mounting seat 52, a second vertical slider 522 and a second vertical driving mechanism 523. The mounting seat 52 is provided with a second vertical guide rail 521. The second vertical slider 522 is movably arranged on the second vertical guide rail 521. The second vertical driving mechanism 523 is fixedly arranged on the mounting seat 52. The output end of the second vertical driving mechanism 523 is connected to the second vertical slider 522. The stirring mechanism 51 is installed on the second vertical slider 522.

[0077] Exemplarily, the rotating shaft 512 is rotatably mounted on the second vertical slider 522, the rotary drive motor 511 is fixedly mounted on the second vertical slider 522, the output end of the rotary drive motor 511 is connected to the upper end of the rotating shaft 512, and the lower end of the rotating shaft 512 extends beyond the second vertical slider 522 for installing blades.

[0078] The second vertical drive mechanism 523 has various structures, such as a motor screw nut mechanism, a telescopic electric cylinder mechanism, etc. Optionally, the second vertical drive mechanism 523 is a telescopic electric cylinder mechanism, the cylinder body is fixedly arranged on the mounting seat 52 , and the electric cylinder telescopic rod is connected to the second vertical slider 522 .

[0079] The second vertical driving mechanism 523 drives the second vertical slider 522 to move along the second vertical guide rail 521, thereby driving the stirring mechanism 51 to rise and fall, thereby achieving stirring at different liquid level depths. When the stirring position is close to the bottom of the barrel, it can better prevent the mixed powder from sinking to the bottom, and when the stirring position is close to the liquid surface, it is conducive to generating more microbubbles.

[0080] In some embodiments, in combination Figure 4 and Figure 6 As shown, the cleaning device 5 also includes a self-cleaning mechanism 53. After the mixed powder is cleaned, the powder to be recovered and the cleaning liquid in the cleaning barrel 3 are poured out, the cleaning barrel 3 is fixed by the clamping device 2, and the inner wall of the cleaning barrel 3 is rinsed by the self-cleaning mechanism 53.

[0081] like Figure 6As shown, the self-cleaning mechanism 53 includes an annular nozzle 531 and a direct current nozzle 532, which are respectively connected to the liquid supply device 4, a plurality of first liquid outlet holes 5311 are arranged at intervals on the outer peripheral surface of the annular nozzle 531, a plurality of second liquid outlet holes 5312 are arranged on the side of the annular nozzle 531 facing the bottom surface of the cleaning barrel 3, and the direct current nozzle 532 passes through the inner circle of the annular nozzle 531 and faces the bottom surface of the cleaning barrel 3.

[0082] The first liquid outlet 5311 is disposed toward the inner wall of the washing tub 3 for flushing the inner wall of the washing tub 3 from top to bottom.

[0083] The liquid outlet direction of the second liquid outlet 5312 is toward the bottom surface of the washing barrel 3, and is used for flushing the bottom surface of the barrel.

[0084] The inventors found that residues are easily deposited on the bottom of the barrel. By setting a DC nozzle 532, the DC nozzle 532 is used to flush the bottom of the barrel 3 from the center of the barrel bottom to the surrounding areas with a large flow rate and a large impact, which can achieve a better cleaning effect.

[0085] In some embodiments, Figure 6 As shown, the direct current nozzle 532 includes a first nozzle 5321 and a second nozzle 5322, and the water outlet of the first nozzle 5321 is higher than the water outlet of the second nozzle 5322. According to the surface height of the residue at the bottom of the barrel, nozzles of different heights can be selected to avoid nozzle blockage and ensure a better flushing effect.

[0086] In some embodiments, Figure 6 As shown, the self-cleaning mechanism 53 also includes a blade 533, which is fixedly mounted on the bottom surface of the annular nozzle 531, and the bottom end of the blade 533 is flush with the bottom end of the second nozzle 5322, or the bottom end of the blade 533 exceeds the bottom end of the second nozzle 5322.

[0087] The blade 533 is a structure used for punching and scraping the residue at the bottom of the barrel. When the self-cleaning mechanism 53 descends, the blade 533 punches the surface of the residue to create cracks. The blade 533 can be driven to move laterally through the transverse movement device 7 to scrape the residue, making it easy to rinse the residue.

[0088] When there is less residue at the bottom of the barrel, the residue is washed away through the first nozzle 5321 with a higher water outlet.

[0089] When there are a lot of residues at the bottom of the barrel and the surface height is high, the blade 533 is used to punch and / or scrape the residues, and then the second nozzle 5322 is used to rinse from below the surface of the residues close to the bottom of the barrel to form a laminar flow on the surface of the bottom of the barrel, so that the residues are fully separated from the bottom of the barrel, achieving a better flushing effect.

[0090] In some embodiments, please combine Figure 4 As shown, the cleaning device 5 further includes a third vertical slider 525 and a third vertical driving mechanism 526, the mounting seat 52 is provided with a third vertical guide rail 524, the third vertical slider 525 is movably arranged on the third vertical guide rail 524, the self-cleaning mechanism 53 is installed on the third vertical slider 525, and the output end of the third vertical driving mechanism 526 is connected to the third vertical slider 525. Exemplarily, the annular nozzle 531 and the DC nozzle 532 of the self-cleaning mechanism 53 are respectively fixedly connected to the third vertical slider 525.

[0091] The third vertical drive mechanism 526 has various structures, such as a motor screw nut mechanism, a telescopic electric cylinder mechanism, etc. Optionally, the third vertical drive mechanism 526 is a telescopic electric cylinder mechanism, the cylinder body is fixedly arranged on the mounting seat 52 , and the electric cylinder telescopic rod is connected to the third vertical slider 525 .

[0092] The third vertical driving mechanism 526 drives the third vertical slider 525 to move along the third vertical guide rail 524, thereby driving the self-cleaning mechanism 53 to rise and fall, thereby further adjusting the height of the self-cleaning mechanism 53, adjusting the flushing height, and achieving punching and cutting of residues.

[0093] By setting up the second vertical drive mechanism 523 and the third vertical drive mechanism 526, the stirring mechanism 51 and the self-cleaning mechanism 53 can be driven to rise and fall respectively, so that the stirring mechanism 51 and the self-cleaning mechanism 53 are staggered in the height direction to avoid mutual interference between the two, thereby ensuring higher cleaning efficiency and better self-cleaning effect.

[0094] Specifically, after the lateral movement device 7 drives the cleaning device 5 to move to the top of the cleaning bucket, the lifting device 6 drives the cleaning device 5 to descend, so that the stirring mechanism 51 enters the cleaning bucket 3, and the second vertical driving mechanism 523 drives the stirring mechanism 51 to further rise and fall to adjust the depth of the blades to achieve sufficient stirring and sufficient generation of microbubbles. At this time, the self-cleaning mechanism 53 is staggered with the blades to avoid interfering with the rotation of the blades. Or further, the third vertical driving mechanism 526 drives the self-cleaning mechanism 53 to rise at this time, so that the self-cleaning mechanism 53 is located above the liquid surface, so as to prevent the self-cleaning mechanism 53 from hindering the full flow and mixing of the liquid.

[0095] When the washing is completed and the washing barrel 3 is rinsed, the third vertical drive mechanism 526 drives the self-cleaning mechanism 53 to descend, so that the annular nozzle 531 and the direct current nozzle 532 exert an impulse toward the inner wall and the bottom of the washing barrel 3, so as to achieve a better self-cleaning and rinsing effect. Optionally, the second vertical drive mechanism 523 drives the stirring device to rise, so that the stirring device avoids the rinsing water flow, avoids reducing the impulse, and improves the rinsing effect.

[0096] Further, in some embodiments, in the cleaning mode, the third vertical drive mechanism 526 drives the self-cleaning mechanism 53 to rise and leave the inside of the cleaning barrel 3, and the lateral movement device 7 drives the cleaning device 5 to move horizontally so that the rotating shaft 512 of the stirring mechanism 51 is located at the center of the cleaning barrel 3, so as to fully stir the cleaning liquid and achieve uniform mixing. At this time, the second vertical drive mechanism 523 is used to adjust the stirring depth of the stirring mechanism 51 in the cleaning barrel 3. After the cleaning is completed and the self-cleaning mode is performed, the second vertical drive mechanism 523 drives the stirring mechanism 51 to rise and leave the inside of the cleaning barrel 3, and the third vertical drive mechanism 526 drives the self-cleaning mechanism 53 to enter the inside of the cleaning barrel 3, and the height of the self-cleaning mechanism 53 is further adjusted by the third vertical drive mechanism 526 to rinse different height positions of the inner side wall of the cleaning barrel 3, and rinse different radial positions of the barrel bottom surface, and to achieve the function of punching out the deposited residues.

[0097] In order to facilitate the supply of cleaning liquid to the cleaning barrel 3, the flushing nozzle 514 of the stirring mechanism 51, the annular nozzle 531 and the direct current nozzle 532 of the self-cleaning mechanism 53, as shown in FIG. Figure 3 As shown, Figure 3 The schematic diagram of the structure of the island valve of the liquid supply device 4 is shown in the figure. The island valve is installed on the horizontal slider 72 so that the island valve and the cleaning device 5 move synchronously to avoid involving the connecting pipeline between the island valve and the cleaning device 5 (not shown in the figure) to ensure the stability of the structure. The island valve includes at least four liquid outlet pipes to respectively provide cleaning liquid to the cleaning barrel 3, the flushing nozzle 514 of the stirring mechanism 51, the annular nozzle 531 and the direct current nozzle 532 of the self-cleaning mechanism 53. According to the type and quantity of the cleaning liquid, the island valve can be provided with at least one liquid inlet pipe (not shown in the figure), which is used to connect the liquid outlet pipe and the corresponding liquid storage device (not shown in the figure).

[0098] In some embodiments, the mixed powder cleaning device further includes a controller (not shown in the figure), which is electrically connected to the liquid supply device 4, the cleaning device 5, the ultrasonic transducer 8, the traverse device 7 and the lifting device 6, respectively, and realizes automatic cleaning and self-cleaning by controlling the water supply amount, water supply sequence, stirring time, the position of the cleaning device 5, and the timing of the ultrasonic transducer 8 and the cleaning device 5.
