Description

Technical Field

[0001] This utility model relates to the field of powder conveying technology, specifically to a material suction device. Background Technology

[0002] Currently, a suction device is generally used to transport graphite powder into a process tank for acid passivation treatment in order to remove impurities from the graphite and improve its purity and quality.

[0003] Existing material suction devices generally include a frame, a material bowl, and a suction mechanism. The material bowl is located inside the frame. The suction mechanism includes a suction nozzle, a flexible hose, a material extraction pipe, and a drive assembly. The suction nozzle is located inside the frame, with its first end extending into the material bowl. The second end of the suction nozzle passes through a through-hole at the top of the frame and connects to the first end of the flexible hose. The second end of the flexible hose extends upward and connects to the material extraction pipe located above the flexible hose. The material extraction pipe is used to connect to a vacuum feeder and a process tank. The drive assembly is located at the top of the frame and is used to drive the suction nozzle to move along the width of the frame. During operation, the vacuum feeder creates a vacuum inside the material extraction pipe, putting it under negative pressure. At this time, the graphite powder in the material bowl can be sucked in by the suction nozzle, then enters the material extraction pipe through the flexible hose, and then enters the process tank. This achieves the transfer of graphite powder to the process tank, where it can then undergo acid passivation treatment.

[0004] While the vacuum feeder evacuates the inside of the suction pipe, the drive assembly moves the suction nozzle along the width of the frame to increase the suction area and improve production efficiency.

[0005] During the movement of the suction nozzle, the nozzle can cause the hose to swing along the width of the frame. The swinging of the hose will cause the second end of the hose to bend repeatedly. Because fatigue damage will occur at the repeated bending of the second end of the hose, the hose needs to be replaced frequently, which is costly. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, this utility model provides a suction device that can avoid repeated bending at the second end of the hose, thereby reducing the frequency of hose replacement and lowering costs.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A material suction device includes a frame, a material bowl, and a material suction mechanism. The material bowl is located within the frame. The material suction mechanism includes a suction nozzle, a flexible hose, a suction tube, and a drive assembly. The suction nozzle is located within the frame, with its first end extending into the material bowl. The second end of the suction nozzle passes through a through hole at the top of the frame and connects to the first end of the flexible hose. The second end of the flexible hose extends upwards. The suction tube is located above the flexible hose and is used to connect to a vacuum feeder and a process tank. The drive assembly is located at the top of the frame and is used to drive the suction nozzle along the frame. The material suction mechanism also includes a connector assembly, which includes a lower connector and an upper connector. The first end of the lower connector is connected to the second end of the hose. The second end of the lower connector is sealed and fitted onto the first end of the upper connector. The lower connector can rotate relative to the upper connector. A strip-shaped through groove extending circumferentially along the outer wall of the second end of the lower connector is provided. A limiting member corresponding to the strip-shaped through groove is provided on the outer wall of the first end of the upper connector. The limiting member cooperates with the strip-shaped through groove. The second end of the upper connector is connected to the material suction pipe.

[0009] As a preferred technical solution, a sealing ring is provided between the inner wall of the second end of the lower connector and the outer wall of the first end of the upper connector, and the sealing ring is sleeved on the first end of the upper connector.

[0010] As a preferred technical solution, a rotating bushing is provided between the inner wall of the second end of the lower connector and the outer wall of the first end of the upper connector, and there are two sealing rings, with the rotating bushing disposed between the two sealing rings.

[0011] As a preferred technical solution, the sealing ring is a packing ring, a silicone ring, or a rubber ring.

[0012] As a preferred technical solution, the first end of the lower connector and the second end of the hose are connected by a clamp.

[0013] As a preferred technical solution, the extraction pipe includes an extraction pipe body and a connecting pipe formed on the outer wall of the extraction pipe body. The bottom end of the extraction pipe body is used to connect with the process tank, the top end of the extraction pipe body is used to connect with the vacuum feeder, the interior of the connecting pipe is in communication with the interior of the extraction pipe body, and the second end of the upper connector is connected to the end of the connecting pipe.

[0014] As a preferred technical solution, the second end of the upper connector is connected to the end of the connecting pipe via a quick-connect chuck.

[0015] As a preferred technical solution, the drive assembly includes a linear module disposed at the top of the frame and a mounting plate disposed at the top of the linear module. The mounting plate is slidably connected to the top of the frame, and the second end of the suction nozzle is connected to the mounting plate.

[0016] As a preferred technical solution, there are two suction nozzles, which are spaced apart along the length of the frame. The number of through holes and hoses corresponds to the number of suction nozzles, which are also two. The two through holes are spaced apart along the length of the frame, and the linear module is located between the two through holes.

[0017] As a preferred technical solution, both the lower connector and the upper connector are bent pipes or straight pipes.

[0018] The beneficial effects of this utility model are as follows: By setting a connector assembly, which includes a lower connector and an upper connector, when the hose swings along the width direction of the frame under the movement of the suction nozzle, the swing of the hose can cause the lower connector to rotate relative to the upper connector between the two ends of the strip groove. This can compensate for the angle of the second end of the hose, thereby avoiding repeated bending of the second end of the hose, thus reducing the frequency of hose replacement and lowering costs.

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions.

[0030] Please refer to Figures 1 to 5 An embodiment of the present invention provides a material suction device, including a frame 10, a material bowl 20 and a material suction mechanism 30.

[0031] The feed bowl 20 is located inside the frame 10. In practical applications, the frame 10 is placed on the ground, and the feed bowl 20 is placed on a support platform, which is also placed on the ground. The feed bowl 20 is used to hold graphite powder.

[0032] The suction mechanism 30 includes a suction nozzle 31, a hose 32, a suction tube 33, a connector assembly 34, and a drive assembly.

[0033] The suction nozzle 31 is located inside the frame 10. The top of the frame 10 has a through hole 11 communicating with the interior of the frame 10. The through hole 11 extends along the width of the frame 10. The first end of the suction nozzle 31 extends into the material bowl 20, and the second end of the suction nozzle 31 passes through the through hole 11 at the top of the frame 10 and connects to the first end of the flexible hose 32. The interior of the suction nozzle 31 communicates with the interior of the flexible hose 32, and the second end of the flexible hose 32 extends upwards. The flexible hose 32 is a corrugated hose. A material extraction pipe 33 is located above the flexible hose 32. The material extraction pipe 33 is used to connect to a vacuum feeder and to a process tank via a connecting pipe.

[0034] The connector assembly 34 includes a lower connector 341 and an upper connector 342. The first end of the lower connector 341 is connected to the second end of the hose 32, and the interior of the hose 32 communicates with the interior of the lower connector 341. The second end of the lower connector 341 is sealed and fitted onto the first end of the upper connector 342. The lower connector 341 is rotatable relative to the upper connector 342, and the interior of the lower connector 342 communicates with the interior of the upper connector 341. A strip-shaped through groove 3411 extending circumferentially along the outer wall of the second end of the lower connector 341 is provided, communicating with the interior of the lower connector 341. A limiting member 3421 corresponding to the strip-shaped through groove 3411 is provided on the outer wall of the first end of the upper connector 342, and the limiting member 3421 cooperates with the strip-shaped through groove 3411. The limiting member 3421 and the strip-shaped through groove 3411 restrict the lower connector 341 from rotating relative to the upper connector 342 between the two ends of the strip-shaped through groove 3411, thus allowing the lower connector 341 to rotate within a certain angle range. The length of the strip-shaped through groove 3411 can be set according to actual conditions. The second end of the upper connector 342 is connected to the extraction pipe 33, and the interior of the upper connector 342 is in communication with the interior of the extraction pipe 33.

[0035] In this embodiment, there are two strip-shaped through slots 3411, which are arranged opposite to each other. The number of limiting members 3421 corresponds to the number of strip-shaped through slots 3411, which is also two.

[0036] The drive assembly is located at the top of the frame 10 and is used to drive the nozzle 31 to move along the width direction of the frame 10.

[0037] During operation, a vacuum feeder evacuates the inside of the extraction pipe 33, creating a negative pressure state. Graphite powder in the mortar 20 is then drawn in through the suction nozzle 31, and subsequently enters the extraction pipe 33 via the flexible hose 32, lower connector 341, and upper connector 342. From there, it enters the process tank through a connecting pipe, thus transporting the graphite powder to the process tank for acid passivation treatment. Simultaneously, the vacuum feeder evacuates the inside of the extraction pipe 33, while the drive assembly moves the suction nozzle 31 along the width of the frame 10, increasing the suction area and improving production efficiency. During the movement of the suction nozzle 31, the suction nozzle 31 can drive the hose 32 to swing along the width direction of the frame 10. The swing of the hose 32 can drive the lower connector 341 to rotate relative to the upper connector 342 between the two ends of the strip groove 3411. This can compensate for the angle of the second end of the hose 32, thereby avoiding repeated bending of the second end of the hose 32, thus reducing the frequency of hose 32 replacement and reducing costs.

[0038] In this embodiment, the limiting member 3421 is a pin, and the outer wall of the first end of the upper connector 342 is provided with a pin hole, in which the pin is installed.

[0039] The second end of the lower connector 341 is sealed and fitted onto the first end of the upper connector 342. For example, a sealing ring 343 is provided between the inner wall of the second end of the lower connector 341 and the outer wall of the first end of the upper connector 342, and the sealing ring 343 is fitted onto the first end of the upper connector 342. Using the sealing ring 343 facilitates the assembly of the lower connector 341 and the upper connector 342.

[0040] A rotating bushing 344 is provided between the inner wall of the second end of the lower connector 341 and the outer wall of the first end of the upper connector 342. Two sealing rings 343 are present, and the rotating bushing 344 is positioned between the two sealing rings 343. The rotating bushing 344 is made of stainless steel. The rotating bushing 344 reduces the friction generated by the rotation of the lower connector 341, protecting the lower connector 341 and extending its service life.

[0041] The sealing ring 343 is a packing ring. Understandably, the sealing ring 343 can also be, for example, a silicone sealing ring or a rubber sealing ring.

[0042] In this embodiment, the first end of the lower connector 341 and the second end of the hose 32 are connected by a clamp, which makes installation simple.

[0043] The extraction pipe 33 includes an extraction pipe body 331 and a connecting pipe 332 formed on the outer wall of the extraction pipe body 331. The bottom end of the extraction pipe body 331 is used to connect to the process tank through the connecting pipe, and the top end of the extraction pipe body 331 is used to connect to the vacuum feeder. The interior of the connecting pipe 332 is connected to the interior of the extraction pipe body 331, and the second end of the upper connector 342 is connected to the end of the connecting pipe 332, with the interior of the upper connector 342 also connected to the interior of the connecting pipe 332. In practical applications, the vacuum feeder evacuates the interior of the extraction pipe body 331, creating a negative pressure state. At this time, the graphite powder in the mortar 20 can be sucked in through the suction nozzle 31, and then enters the extraction pipe body 331 through the hose 32, lower connector 341, upper connector 342, and connecting pipe 332, and then enters the process tank through the connecting pipe.

[0044] The second end of the upper connector 342 is connected to the end of the connecting pipe 332 via a quick-connect chuck, making installation easy.

[0045] In this embodiment, both the lower connector 341 and the upper connector 342 are bent pipes. Using bent pipes facilitates the rotation of the lower connector 341 relative to the upper connector 342 by the flexible hose 32. The bent pipe is preferably a 90-degree bend, but it is understood that the bend can also have other angles.

[0046] In other embodiments, both the lower connector 341 and the upper connector 342 may be straight pipes, which can be set according to the actual situation.

[0047] The drive assembly includes a linear module 35 disposed at the top of the frame 10 and a mounting plate 36 disposed at the top of the linear module 35. The length direction of the linear module 35 is the same as the width direction of the frame 10, and the length direction of the mounting plate 36 is the same as the length direction of the frame 10. The mounting plate 36 is slidably connected to the top of the frame 10, and the second end of the suction nozzle 31 is connected to the mounting plate 36. The linear module 35 is used to drive the mounting plate 36 to move along the width direction of the frame 10, thereby driving the suction nozzle 31 to move along the width direction of the frame 10.

[0048] In this embodiment, a connector 311 is sleeved on the outer wall of the second end of the suction nozzle 31, and the connector 311 is disposed at the bottom end of the mounting plate 36. The second end of the suction nozzle 31 and the first end of the hose 32 are connected by a connector 312, which passes through the mounting hole 363 of the mounting plate 36.

[0049] In this embodiment, there are two suction nozzles 31, which are spaced apart along the length of the frame 10. The number of through holes 11, hoses 32, and connecting pipes 332 corresponds to the number of suction nozzles 31, which are also two. The two through holes 11 are spaced apart along the length of the frame 10. The linear module 35 is located between the two through holes 11. The two connecting pipes 332 and the material extraction pipe body 331 form a Y-shaped structure.

[0050] The mounting plate 36 is slidably connected to the top of the frame 10, which improves the stability of the movement of the mounting plate 36, and thus improves the stability of the movement of the suction nozzle 31. Specifically, two mounting blocks 361 are respectively provided at both ends of the bottom of the mounting plate 36, and two slide rails 362 corresponding to the two mounting blocks 361 are provided at the top of the frame 10. The length direction of the slide rails 362 is the same as the width direction of the frame 10. Two through holes 11 are located between the two slide rails 362. The bottom of the mounting block 361 is provided with a slider, and the sliders at the bottom of the two mounting blocks 361 are slidably engaged with the two slide rails 362 respectively.

[0051] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments.
