[0034] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0035] A copper powder filtering device according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0036] like Figure 1-Figure 7 As shown, a copper powder filtering device according to an embodiment of the utility model may include a housing 1, a water filtering assembly 2, a drying rack 3 and a drying assembly 4.

[0037] A material receiving groove 5 is provided on the surface of the box body 1 , and a material drawer 6 is provided inside the material receiving groove 5 . A controller 7 is provided on the surface of the box body 1 .

[0038] The water filter assembly 2 may include a water supply assembly 21 , a filter assembly 22 , a water receiving frame 23 and a drive assembly 24 .

[0039] Among them, the water supply component 21, the filter component 22 and the water receiving frame 23 are arranged inside the box body 1 from top to bottom, and the driving component 24 is arranged inside the box body 1. The driving component 24 is connected to one end of the water supply component 21 and one end of the filter component 22 respectively.

[0040] The drying rack 3 is arranged inside the box body 1 and located on one side of the water filter assembly 2 . A vibrator 31 is arranged on the surface of the drying rack 3 .

[0041] The drying assembly 4 may include a spiral conveying pipe 41 and a cyclone separator 42 .

[0042] Among them, the spiral conveying pipe 41 is arranged on the inner wall of the drying rack 3 and is connected to one end of the external hot air conveying pipe. The cyclone separator 42 is arranged on the inner wall of the drying rack 3 and is located on one side of the bottom of the spiral conveying pipe 41. One end of the cyclone separator 42 is connected to one end of the spiral conveying pipe 41, and the other end of the cyclone separator 42 passes through the interior of the feeding trough 5.

[0043] The water supply assembly 21 , the filter assembly 22 , the drive assembly 24 and the vibrator 31 are electrically connected to the controller 7 , respectively.

[0044] It should be noted that the inner wall of the water receiving frame 23 described in this embodiment is provided with a liquid level sensor (not shown in the figure), the liquid level sensor is electrically connected to the controller 7, and a water circulation pipe rack is provided on the surface of the water receiving frame 23 and is connected to the inside of the water receiving frame 23. The liquid level sensor and the water circulation pipe rack are provided to facilitate timely drainage of the water inside the water receiving frame 23, and the use effect is good.

[0045] It can be understood that the external hot air delivery duct (not shown in the figure) is obliquely arranged on the surface of the spiral delivery duct 41 and is connected to the inside of the spiral delivery duct 41. The air outlet of the external hot air delivery duct is arranged downward inside the spiral delivery duct 41. This design ensures that the hot air will only blow the copper powder downward, effectively preventing the copper powder from flowing back, and the use effect is good.

[0046] Specifically, one end of the mixed water pipeline is connected to one end of the water supply component 21, and the mixed water is injected into the box body 1 through the water supply component 21. After the mixed water injected into the box body 1 is filtered by the filter component 22, the copper powder is blocked inside the filter component 22, and the washing water falls into the water receiving frame 23 under the action of gravity. After the mixed water injection reaches the set amount, the controller 7 controls the driving component 24 and the vibrator 31 to operate respectively. The operation of the driving component 24 drives the lower water roller 212 in the water supply component 21 to close, so that the mixed water cannot continue to fall. At the same time, the operation of the driving component 24 also drives the filter component 22 to move to the top of the drying rack 3, and moves the discharge pipe 223 at the bottom thereof to the position of the spiral conveying pipe 41, and is connected to the spiral conveying pipe. 41 is connected internally, when the discharge pipe 223 moves to the position of the spiral conveying pipe 41, the operation of the vibrator 31 drives the filter frame 221 in the filter assembly 22 to vibrate, so that the copper powder inside it automatically falls into the spiral conveying pipe 41 under the action of vibration, and after the copper powder falls into the spiral conveying pipe 41, the hot air transported by the external hot air conveying pipe to the spiral conveying pipe 41 continuously performs hot air drying operation on the copper powder, and the copper powder enters the cyclone separator 42 after hot air drying, and the copper powder entering the cyclone separator 42 falls into the material extraction 6 for collection under the action of gravity, and the hot air is discharged from the air outlet of the cyclone separator 42, and continuously heats the outer surface of the spiral conveying pipe 41, so as to further improve the drying effect.

[0047] In one embodiment of the present invention, Figure 4 As shown, the water supply assembly 21 may include a branch pipe rack 211, a water discharge roller 212, an adjusting gear 213, a water inlet pipe 214, a flow detector 215 and a drain pipe 216.

[0048] Among them, the branch pipe rack 211 is arranged inside the box body 1, the water discharge roller 212 is rotatably connected to the inner wall of the branch pipe rack 211, a water trough 2121 is opened on the surface of the water discharge roller 212, the adjusting gear 213 is symmetrically rotatably connected to the surface of the branch pipe rack 211, and is fixedly connected to one end of the central axis of the water discharge roller 212, the water inlet pipe 214 is arranged on the top of the branch pipe rack 211, the flow detector 215 is arranged on the surface of the water inlet pipe 214, one end of the water inlet pipe 214 is connected to the inside of the branch pipe rack 211, the other end of the water inlet pipe 214 passes through the top of the box body 1, and is connected to one end of the external mixed water pipeline, and the drainage pipe 216 is evenly arranged at the bottom of the branch pipe rack 211, and is connected to the inside of the branch pipe rack 211.

[0049] It should be noted that the external mixed water pipeline described in this embodiment is provided with an electric control valve, and is electrically connected to the controller 7 .

[0050] It can be understood that the electric control valve and the water discharge roller 212 provide dual protection.

[0051] Specifically, the mixed water enters the branch rack 211 through the water inlet pipe 214. During this process, the flow detector 215 monitors the mixed water flow in real time. When the set value is reached, the electric control valve on the external mixed water pipeline is controlled to close. During this process, the driving adjustment gear 213 can rotate to synchronously drive the water discharge roller 212 to rotate, and the rotation of the water discharge roller 212 can synchronously drive the lower water tank 2121 to rotate. When the lower water tank 2121 is in a vertical state, the water inside the branch rack 211 flows to the drain pipe 216 through the lower water tank 2121. When the lower water tank 2121 is in a horizontal state, the water inside the branch rack 211 cannot flow to the drain pipe 216 through the lower water tank 2121.

[0052] In one embodiment of the present invention, Figure 6 As shown, the filter assembly 22 may include a filter frame 221 , a filter tank 222 , a discharge pipe 223 , a tapered tank 224 and an elastic reset mechanism 225 .

The filter tank 222 is evenly opened on the surface of the filter frame 221. The discharge pipe 223 is evenly arranged at the bottom of the filter frame 221 and is connected to the inside of the filter tank 222. The discharge pipe 223 is provided with a solenoid valve 2231. The conical groove 224 is symmetrically opened on the surface of the filter frame 221 and is located on one side of the filter tank 222. The conical groove 224 corresponds to the position of one end of the driving component 24. The elastic reset mechanism 225 is symmetrically arranged on the surface of the filter frame 221, and one end of the elastic reset mechanism 225 abuts against the inner wall of the box body 1.

[0054] It should be noted that a conical filter base frame 2211 is provided at the bottom of the filter frame 221 described in this embodiment.

[0055] In addition, it should be noted that a solenoid valve 2231 is provided on the surface of the discharge pipe 223 and is electrically connected to the controller 7 .

[0056] Specifically, the mixed water falls into the filter tank 222 under the action of gravity, wherein the copper powder in the mixed water is filtered by the conical filter bottom frame 2211 and remains in the conical filter bottom frame 2211, while the water falls into the water receiving frame 23 under the action of gravity. When the conical block 244 in the driving component 24 enters the conical tank 224 and squeezes the conical tank 224 to move to one side, it will synchronously drive the filter frame 221 to move to one side of the drying rack 3 until the discharge pipe 223 moves to One end of the guide groove 32 corresponds to the position of the spiral conveying pipe 41. When the discharge pipe 223 corresponds to the position of the spiral conveying pipe 41, the filter frame 221 synchronously contacts the surface of the vibrator 31, and the controller 7 controls the vibrator 31 to be powered on and controls the solenoid valve 2231 to be opened. Under the vibration of the vibrator 31, the copper powder inside the conical filter base 2211 is automatically concentrated at the discharge pipe 223 and falls into the spiral conveying pipe 41 from the discharge pipe 223.

[0057] In one embodiment of the present invention, Figure 4 As shown, the driving assembly 24 may include a speed change gear 241 , a sliding gear seat 242 , an electric telescopic rod 243 and a tapered block 244 .

[0058] Among them, the speed change gear 241 is symmetrically rotatably connected to the inner wall of the box body 1 and meshes with the adjusting gear 213. The sliding gear seat 242 is symmetrically slidably connected to the inner wall of the box body 1 and meshes with the speed change gear 241. The electric telescopic rod 243 is symmetrically arranged on the inner wall of the box body 1. One end of the electric telescopic rod 243 passes through the top of the box body 1, and the other end of the electric telescopic rod 243 is fixedly connected to the top of the sliding gear seat 242. The conical block 244 is arranged at the bottom of the sliding gear seat 242 and corresponds to the position of the conical groove 224. The conical block 244 is slidably connected to the inner wall of the conical groove 224.

[0059] It should be noted that the outer diameter of the speed change gear 241 described in this embodiment is smaller than the outer diameter of the adjusting gear 213 , and the tooth modules of the speed change gear 241 and the adjusting gear 213 are set according to a set ratio.

[0060] In addition, it should be noted that the outer dimensions of the conical block 244 and the conical groove 224 are compatible.

[0061] Specifically, the controller 7 controls the electric telescopic rod 243 to be powered on and run. The electric telescopic rod 243 runs to drive one end thereof to extend, and during the extension process, the sliding gear seat 242 and the conical block 244 are synchronously driven to move downward. During the downward movement of the sliding gear seat 242, the speed change gear 241 is synchronously driven to rotate. The rotation of the speed change gear 241 synchronously drives the adjustment gear 213 to rotate. During the descent process, the conical block 244 enters the conical groove 224 and synchronously squeezes the filter frame 221 to move toward the side of the drying rack 3.

[0062] In one embodiment of the present invention, Figure 7 As shown, guide grooves 32 are evenly formed on the top of the drying rack 3 and correspond to the positions of the discharge pipes 223 . The guide grooves 32 are connected to the interior of the drying rack 3 .

[0064] It should be noted that the guide groove 32 described in this embodiment not only plays a guiding and limiting role, but also ensures the sealing of the connection between the discharge pipe 223 and the drying rack 3. The circulation duct 33 is provided to circulate the hot air of the drying rack 3, thereby reducing energy consumption and achieving good use effect.

[0065] In addition, it should be noted that one end of the spiral conveying pipe 41 is connected to the inside of the guide groove 32 , so that the copper powder falling into the guide groove 32 can directly enter the inside of the spiral conveying pipe 41 .

[0066] In one embodiment of the present invention, Figure 7 As shown, a filter screen (not shown in the figure) is arranged inside the air outlet of the cyclone separator 42, and a magnetic filter rod (not shown in the figure) is arranged inside the discharge port of the cyclone separator 42.
