[0048] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0049] In order to solve the technical problem that the waste materials in the production process are currently simply centralized and collected, so that the recycled waste materials need to be reprocessed, resulting in low production efficiency, the utility model provides a recycling device for flux production waste, which can achieve crushing and screening of the waste materials in the flux production by arranging a crushing component 3, a screening component 4 and an exhaust component 5 inside the shell 1, and classify the materials according to different particle sizes to avoid subsequent processing, thereby saving production costs and improving production efficiency.

[0050] It should be noted that the device for recycling waste from flux production described in the present invention is used for but not limited to the field of flux production technology, etc. For the sake of convenience, in the present invention, only the device for recycling waste from flux production is used in the field of flux production technology as an example for explanation, and the principle of applying the device for recycling waste from flux production to other types of equipment is essentially the same as the principle of applying it to the field of flux production technology, which will not be described in detail here.

[0051] See also Figures 1 to 5 , Figure 1 This is a structural schematic diagram of a device for recycling waste from welding flux production in one embodiment of the present invention. The device for recycling waste from welding flux production includes: a shell 1, a lower hopper 2, a crushing assembly 3, at least one screening assembly 4 and an exhaust assembly 5. The lower hopper 2 is connected to the shell 1 and is communicated with the interior of the shell 1. The crushing assembly 3 is arranged relative to the lower hopper 2 and is rotatably connected to the inner wall of the shell 1 for crushing materials. The screening assembly 4 includes a screen 41 and a first drawer 42. The screen 41 is tilted and arranged below the crushing assembly 3 and can rotate relative to the shell 1. The first drawer 42 is slidably connected to the bottom of the screen 41. The exhaust assembly 5 is connected to the shell 1, and the air inlet end of the exhaust assembly 5 is communicated with the interior of the shell 1.

[0052] In this device, the interior of the shell 1 is hollow, the lower hopper 2 is connected to the shell 1 and communicated with the interior of the shell 1, the crushing component 3 is arranged relative to the lower hopper 2, and is rotatably connected to the inner wall of the shell 1 for crushing materials, at least one screen 41 is arranged below the crushing component 3, and can be rotated relative to the shell 1, for crushing the material after the screen 41 is crushed, the first drawer 42 is arranged below the screen 41, for centrally collecting the screened materials, and the air inlet end of the exhaust component 5 is communicated with the interior of the shell 1, for removing the exhaust gas generated when crushing the material and the dust generated during the screening process.

[0053] Compared with the existing technology, by arranging a crushing component 3, a screening component 4 and an exhaust component 5 inside the shell 1, the waste materials during the production of the flux are crushed and screened, and the materials are classified according to different particle sizes to avoid subsequent processing, which can save production costs and improve production efficiency. It can solve the technical problem in the existing technology that the waste materials in the production process are currently simply centralized and unified, so that the recycled waste materials need to be reprocessed, resulting in low production efficiency.

[0054] Furthermore, the lower hopper 2 is a funnel-shaped structure that is common and easy to purchase on the market. The waste generated by the flux production directly enters the interior of the shell 1 through the lower hopper 2, and is crushed and screened to achieve the purpose of classification.

[0055] In this embodiment, the crushing assembly 3 includes two crushing rollers 31, two gears 32 and a drive motor 33. The two crushing rollers 31 are arranged between the lower hopper 2 and the screen 41 at intervals, and can rotate respectively relative to the inner wall of the shell 1. The gears 32 are arranged in a one-to-one correspondence with the crushing rollers 31 and are coaxially arranged with the crushing rollers 31. The two gears 32 can engage with each other. The fixed end of the drive motor 33 is connected to the shell 1, and the output shaft is connected to a gear 32, which is used to drive the two gears 32 to rotate in opposite directions.

[0056] The driving motor 33 drives the two gears 32 to mesh with each other, so that the two oppositely arranged crushing rollers 31 rotate in opposite directions, thereby achieving the purpose of crushing the material.

[0057] Furthermore, the crushing roller 31, gear 32 and drive motor 33 are all common and easily purchased equipment on the market. They are conventional settings well known to those skilled in the art and will not be described in detail here.

[0058] In this embodiment, the screen 41 is arranged relative to the crushing assembly 3, and one end of the screen 41 is rotatably connected to the inner wall of the shell 1. The screening assembly 4 also includes at least one support rod 43 and at least one sliding member 44. One end of the support rod 43 is hinged to the inner wall of the shell 1, and one end of the sliding member 44 is slidably connected to the screen 41, and the other end is hinged to the other end of the support rod 43.

[0059] A movable hinge structure is formed between the screen 41, the sliding member 44, the support rod 43 and the shell 1, so that the screen 41 can rotate relative to the inner wall of the shell 1. The rotated screen 41 can facilitate the screen 41 to screen the material.

[0060] Furthermore, the inclined screen 41 allows the screened materials with large particle sizes to flow downward along the inclined screen 41, thereby achieving separation and collection of the materials.

[0061] In one embodiment, see Figure 3 The screen 41 is provided with at least one slide groove along its length direction. The sliding member 44 includes a sliding block 441 and an elastic part 442. One end of the sliding block 441 is slidably embedded in the slide groove, and the other end is hinged to the other end of the support rod 43. The elastic part 442 is arranged along the guide of the slide groove, and one end of the elastic part 442 is connected to the sliding block 441 and the other end is connected to the inner wall of the slide groove, which is used to push the sliding block 441 to automatically reset after sliding relative to the slide groove.

[0062] The sliding block 441 cooperates with the slide groove to enable the other end of the support rod 43 to slide relative to the screen 41. The elastic part 442 can push the other end of the support rod 43 to slide and then automatically reset, so that the material falls on the screen 41 and pushes the screen 41 to vibrate reciprocatingly, which is beneficial to the screening of the material.

[0063] Furthermore, the elastic portion 442 here is a spring, a spring sheet and an elastic block that are common and easy to purchase on the market. This is a conventional setting known to those skilled in the art and will not be described in detail here.

[0064] In one embodiment, see Figure 5 The sliding block 441 has at least one spherical groove relative to the inner wall of the slide groove, and the sliding member 44 also includes at least one rolling portion 443. The rolling portion 443 is arranged in a one-to-one correspondence with the spherical groove. The rolling portion 443 is embedded in the spherical groove and abuts against the inner wall of the slide groove.

[0065] The cooperation between the rolling portion 443 and the spherical groove can reduce the friction force when the sliding block 441 slides relative to the sliding groove.

[0066] Furthermore, the rolling part 443 in the present device is a steel ball that is common and easily purchased on the market. The steel ball here belongs to a conventional setting well known to those skilled in the art and will not be described in detail here.

[0067] In one embodiment, see Figure 2 、 Figure 4 There are slide grooves on both sides of the screen 41. There are two sliding blocks 441 in the screening component 4. The two sliding blocks 441 are slidably embedded in the two side walls of the screen 41.

[0068] By providing support rods 43 and sliding blocks 441 on both sides of the screen 41 , the stability of the screen 41 during reciprocating vibration can be improved.

[0069] In one embodiment, see Figure 2 、 Figure 4 A first through slot is provided on the outer wall of the shell 1, and the first through slot is connected to the interior of the shell 1. The screening assembly 4 also includes two abutment bars 45, which are arranged parallel to each other relative to the opening of the first through slot and are respectively connected to the inner walls of the shell 1 on opposite sides. The first drawer 42 is inserted into the first through slot and can slide along the guide of the abutment bar 45.

[0070] The two abutment bars 45 are respectively provided on both sides of the first drawer 42 and are respectively connected to the inner wall of the housing 1 , so as to support and connect the first drawer 42 when sliding relative to the housing 1 .

[0071] Furthermore, the sliding of the first drawer 42 relative to the housing 1 can facilitate the user to collect the separated materials.

[0072] In one embodiment, see Figure 2 、 Figure 4 There are two screening assemblies 4 , and the two screens 41 are arranged on the inner walls of the shell 1 on opposite sides, and the two screens 41 are staggered along the height direction of the shell 1 .

[0073] By providing two screens 41 that are opposite to each other and staggered along the height direction of the shell 1, the materials can be separated efficiently and the problem of incomplete separation can be avoided.

[0074] In this embodiment, Figure 4 As shown, the exhaust assembly 5 includes an exhaust pipe 51 and an exhaust pump 52. One end of the exhaust pipe 51 is built into the shell 1, and the fixed end of the exhaust pump 52 is connected to the top of the shell 1, and the air inlet end is connected to the other end of the exhaust pipe 51.

[0075] By providing the exhaust pipe 51 and the exhaust pump 52 , the waste gas generated during the separation and crushing process and the dust generated during the screening process can be extracted.

[0076] Furthermore, the vacuum pump 52 in this device is a common and easily purchased device on the market. It is a conventional setting well known to those skilled in the art and will not be described in detail here.

[0077] In this embodiment, a second through groove is further provided on the outer wall of the shell 1, which is arranged below the screen 41 and is connected to the interior of the shell 1. The recycling device for flux production waste also includes a second drawer 6, which is slidably inserted into the second through groove.

[0078] By providing the second drawer 6, the separated large particle materials can be collected.

[0079] Furthermore, the first drawer 42 and the second drawer 6 are common and easily purchased devices on the market. They are conventional settings well known to those skilled in the art and will not be described in detail here.

[0080] In order to better understand the present invention, the following Figures 1 to 5 The technical solution of the utility model is described in detail:

[0081] The interior of the shell 1 is hollow, and the lower hopper 2 is connected to the shell 1 and communicates with the interior of the shell 1. The crushing assembly 3 is arranged relative to the lower hopper 2 and is rotatably connected to the inner wall of the shell 1 for crushing materials. At least one screen 41 is arranged below the crushing assembly 3 and can rotate relative to the shell 1 for the material after the screen 41 has been crushed. The first drawer 42 is arranged below the screen 41 for collecting the screened materials. The air inlet end of the exhaust assembly 5 is communicated with the interior of the shell 1 for removing the waste gas generated when the materials are crushed and the dust generated during the screening process. Compared with the existing technology, by arranging the crushing assembly 3, the screening assembly 4 and the exhaust assembly 5 inside the shell 1, the waste materials during the flux production are crushed and screened, and the materials are classified according to different particle sizes to avoid subsequent processing, which can save production costs and improve production efficiency.

[0082] The specific working process of the present invention is that when in use, the waste material produced by the flux enters the interior of the shell 1 through the lower hopper 2, and the driving motor 33 drives the two crushing rollers 31 to rotate around their axes respectively and crush the material. Then the material falls onto the screen 41 from the gap between the two crushing rollers 31, and slightly pushes the screen 41 to swing relative to the shell 1. At the same time, the material passes through the sieve holes on the screen 41 and is screened. The screen 41 automatically resets under the elastic restoring force of the elastic part 442 and forms a reciprocating swing. Then the small-particle material falls into the first drawer 42, and the last part of the material that has not been separated in time slides into the bottom along the guide of the screen 41, and is separated again. The small-particle material is collected in the first drawer 42, and the large-particle material is collected in the second drawer 6. At the same time, the vacuum pump 52 extracts the waste gas generated during the separation and crushing process and the dust generated during the screening process, thereby realizing the separation and classification of the recycled materials and improving production efficiency.

[0083] The device, through the above structure, can solve the technical problem in the prior art that the waste materials in the production process are simply centralized and collected, so the recycled waste materials need to be reprocessed, resulting in low production efficiency.

[0084] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
