Description

Technical Field

[0001] This invention relates to the field of metal recycling technology, specifically to a recycling device for dust removal during metal material cutting. Background Technology

[0002] Metals are substances that have luster, are malleable, and are good at conducting electricity and heat. Most of these properties of metals are related to the presence of free electrons in the metal crystal. Only a very few metals, such as gold, platinum, silver, and bismuth, exist in a free state. When using metal rods, they need to be cut according to the actual situation to obtain metal sheets of appropriate length. In order to reduce the pollution caused by the cutting work, dust removal devices are usually set up to clean up the dust and waste generated during the cutting process.

[0003] When a dust collector removes dust from a processing table, the sucked-in dust is mixed with metal powder or metal shavings. The dust collector uses a fixed filter to separate the dust and metal shavings. Because a large amount of metal shavings is generated during metal cutting, typical dust collectors have a cleaning and collection structure to centrally clean and collect the filtered material from the filter, allowing for the recycling and reuse of the metal shavings. However, since dust and metal shavings are collected together during dust removal, a large amount of useless dust is mixed with the metal shavings during recycling. How to separate the metal shavings from the dust, allowing for independent recycling of the metal shavings, is a pressing problem to be solved in dust collection and recycling systems for metal cutting. Therefore, we propose a recycling device for dust collection in metal cutting. Summary of the Invention

[0004] The purpose of this invention is to provide a recycling device for dust removal during metal material cutting, which solves the problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A dust collection device for cutting metal materials includes a body, an air inlet and an air outlet disposed on the body, and an induced draft fan for dust collection; an inner liner installed inside the body, the inner liner having a magnetic zone and a non-magnetic zone, the magnetic zone of the inner liner being connected to a magnetic ring; a transmission device that intermittently drives a filter screen rotating on the inner liner, and a motor driving the transmission device, the filter screen being cylindrical, the motor being mounted on the body; and two shaking components located in the magnetic zone and the non-magnetic zone respectively, both of which are disposed inside the body.

[0007] Preferably, the filter barrel screen includes a fixed ring head, which rotates on the inner liner of the flow channel. Multiple guide baffles arranged in a circular array are fixedly connected to the fixed ring head, and a convex filter plate is slidably connected between every two adjacent guide baffles. The convex filter plate is connected to the fixed ring head by a spring, and a toothed ring is fixedly connected to the fixed ring head.

[0008] Preferably, the guide baffle has two corresponding straight guide angles on the end away from the fixed ring head.

[0009] Preferably, the transmission device includes a connecting plate and a guide seat installed inside the machine body. One end of the connecting plate passes through the interior of the machine body and is fixedly connected to the output shaft of the motor. The other end of the connecting plate is fixedly connected to a double-rail gear plate. A drive gear plate is movably connected to the double-rail gear plate through a positioning shaft. A spring is connected between the drive gear plate and the positioning shaft, and the drive gear ring is driven when the drive gear plate is squeezed by the guide seat.

[0010] Preferably, the connecting plate has a clearance groove for the drive tooth plate to slide.

[0011] Preferably, the dual-track toothed disc is composed of a dust-shaking toothed disc and a metal powder-shaking toothed disc. The dust-shaking toothed disc is used to engage the shaking component in the magnetic zone, and the metal powder-shaking toothed disc is used to engage the shaking component in the non-magnetic zone.

[0012] Preferably, the shaking component includes a connecting shaft and a gear mounted on the connecting shaft. One end of the connecting shaft is rotatably connected to the inside of the machine body, and a shaking rod is fixedly connected to the surface of the connecting shaft.

[0013] Preferably, a dust collection base and a metal dust collection base are respectively installed at the bottom of the machine body. The dust collection base is located below the magnetic area of ​​the inner liner, and the metal dust collection base is located below the non-magnetic area of ​​the inner liner.

[0014] Preferably, the inner liner of the drainage chamber has a drainage cavity inside, the air inlet of the drainage cavity is positioned corresponding to the air inlet, and the air outlet of the drainage cavity is positioned corresponding to the air outlet.

[0015] By employing the above technical solution, the present invention provides a recycling device for dust removal during metal material cutting. It possesses at least the following beneficial effects:

[0016] (1) The metal material cutting dust removal recycling device drives the filter barrel screen to rotate and filter in the dust collector by setting a motor drive transmission device. During the rotation, the filter material on the filter barrel screen in the magnetic zone and non-magnetic zone of the inner liner is shaken by the shaking component. The shaking work in the magnetic zone achieves the effect of independently shaking the dust, and the shaking work in the non-magnetic zone achieves the effect of independently feeding and collecting metal powder, thereby solving the problem that the existing dust collector cannot achieve the separation and recycling of dust and metal powder.

[0017] (2) The metal material cutting dust removal recycling device is equipped with a filter barrel screen. The filter barrel screen has multiple convex filter plates that can move outward along the center. After being hit by the shaking component, the convex filter plates will produce a shaking effect and can be reset by elastic force during the impact. Then, the vibration force generated by the shaking is used to realize the feeding of the filter material. Combined with the two straight guide angles on the guide baffle, the sliding convex filter plates are limited and sealed.

[0018] (3) The metal material cutting dust removal recycling device is equipped with a transmission device, which drives the filter barrel screen to rotate intermittently and the two shaking parts to shake the material. The double-rail toothed disc is composed of a dust shaking toothed disc and a metal powder shaking toothed disc. The dust shaking toothed disc is used to mesh with the shaking parts in the magnetic zone, and the metal powder shaking toothed disc is used to mesh with the shaking parts in the non-magnetic zone. This allows the convex filter plate to achieve the effects of moving filtration, dust screening and metal powder collection in the continuous rotation, and further achieve the effect of circulating filtration and recycling.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1-11 The present invention provides a technical solution:

[0034] A dust collection device for cutting metal materials includes a body 1, an air inlet 2 and an air outlet 3 disposed on the body 1, and an induced draft fan 4 for dust collection; an inner liner 5 installed inside the body 1, the inner liner 5 having a magnetic zone and a non-magnetic zone, a magnetic ring 6 fixedly connected to the magnetic zone of the inner liner 5 to provide magnetic force, the magnetic ring 6 being located in the lower region of the inner liner 5, an inner liner 5 having an inner liner cavity 51, the air inlet of the inner liner 51 corresponding to the position of the air inlet 2, and the air outlet of the inner liner 51 corresponding to the position of the air outlet 3; a filter screen 7 rotating on the inner liner 5, a transmission device 8 intermittently driving the filter screen 7 to rotate, and a motor 10 driving the transmission device 8; the induced draft fan 4 drawing dust from outside the dust collection head through the air inlet 2. The incoming material is discharged through the air outlet 3 according to the airflow. During the circulation, the filter screen 7 filters and isolates the intake gas. The dust and metal particles entrained in the gas are filtered onto the surface of the filter screen 7. When the filter screen 7 is driven to rotate by the transmission device 8 driven by the motor 10, the metal particles on the filter screen 7 are always attached to the filter screen 7 in the magnetic area due to the influence of the magnetic ring 6, thus ensuring stable transmission of the filtered metal particles. The magnetic force disappears when the rotation reaches the non-magnetic area, and the metal particles can be discharged independently. The filter screen 7 is cylindrical. The surface of the motor 10 is detachably mounted on the machine body 1 by bolts. There are two shaking parts 9 located in the magnetic area and the non-magnetic area respectively, and both shaking parts 9 are set inside the machine body 1. The bottom of the machine body 1 is equipped with a dust collection base 11 and a metal dust collection base 12. The dust collection base 11 is located below the magnetic zone of the inner liner 5 and collects dust from the filter screen 7 containing dust and metal dust during the shaking process. The metal dust collection base 12 is located below the non-magnetic zone of the inner liner 5 and collects the metal dust on the filter screen 7 after the dust has been shaken off.

[0035] In this embodiment, the filter barrel screen 7 includes a fixed ring head 71, which rotates on the inner liner 5. The filter barrel screen 7 is in a state of being fitted onto the inner liner 5. A plurality of guide baffles 72 arranged in a circular array are fixedly connected to the fixed ring head 71. Two corresponding straight guide angles 721 are provided on the end of the guide baffles 72 away from the fixed ring head 71. A convex filter plate 73 is slidably connected between each pair of adjacent guide baffles 72. The straight guide angles 721 are used to limit and close the sliding convex filter plate 73. The side of the convex filter plate 73 close to the fixed ring head 71 is connected to the fixed ring head 71 by a spring. A toothed ring ring 74 is fixedly connected to the fixed ring head 71. A plurality of toothed plates are arranged in a circular array on the toothed ring ring 74.

[0036] Furthermore, the transmission device 8 includes a connecting plate 81 and a guide seat 85 installed inside the machine body 1, such as... Figure 9As shown, the two sides of the guide seat 85 are set as inclined surfaces to guide the drive tooth plate 84 during rotation. One end of the connecting plate 81 passes through the interior of the machine body 1 and is detachably fixedly connected to the output shaft of the motor 10. The other end of the connecting plate 81 is fixedly connected to a double-rail toothed plate 82. The double-rail toothed plate 82 is composed of a dust shaking toothed plate 821 and a metal powder shaking toothed plate 822. The two toothed plates are respectively provided with toothless areas. The dust shaking toothed plate 821 is used to engage the shaking component 9 in the magnetic area, and the metal powder shaking toothed plate 822 is used to engage the shaking component 9 in the non-magnetic area. A positioning shaft 83 is fixedly connected to the double-rail toothed plate 82. The drive toothed plate 84 is slidably connected to the surface of the positioning shaft 83. A clearance groove 86 is provided on the connecting plate 81 for the drive toothed plate 84 to slide. A spring is connected between the surface of the drive toothed plate 84 and the surface of the positioning shaft 83, and the drive toothed plate 84 is driven by the toothed ring 74 when it is pressed by the guide seat 85.

[0037] Furthermore, the shaking component 9 includes a connecting shaft 91 and a gear 92 mounted on the connecting shaft 91. One end of the connecting shaft 91 is rotatably connected to the inside of the machine body 1. A shaking rod 93 is fixedly connected to the surface of the connecting shaft 91. When the shaking component 9, located in the magnetic zone, rotates, it impacts the convex filter plate 73 at that location. The convex filter plate 73 vibrates under the force to discharge the material. Since the convex filter plate 73 is located in the magnetic zone, the metal powder in the impurities will be continuously attracted to the convex filter plate 73 due to the magnetic force during the vibration. The convex filter plate 73 can only target impurities. The dust is shaken and fed into the dust collection base 11, thus separating the dust from the metal dust. When the shaking component 9 located in the non-magnetic zone rotates, the metal dust at this position loses the magnetic attraction and is shaken and fed by the convex filter plate 73. This solves the problem that existing dust collectors cannot separate and recycle dust from metal dust. At the same time, the convex filter plate 73 continuously rotates and sequentially achieves moving filtration, dust screening, and metal dust collection, further achieving the effect of cyclic filtration and recycling.

[0038] In use, the dust collection device for metal material cutting of the present invention has a dust removal head connected to the air inlet 2 of the machine body 1 for dust removal of the working area of ​​the metal cutting table. The induced draft fan 4 draws dust from the dust removal head through the air inlet 2, and the drawn-in material is discharged to the air outlet 3 according to the airflow. During the circulation, the filter screen 7 filters and isolates the drawn-in gas, and the impurities and metal shavings entrained in the gas are filtered onto the surface of the filter screen 7. By starting the motor 10, the output shaft of the motor 10 drives the double-rail gear disk 82 to rotate as a whole through the connecting plate 81. During rotation, the double-rail gear disk 82 first drives the drive gear plate 84, which is elastically connected to its positioning shaft 83, to rotate. During the initial rotation, the drive gear plate 84 gradually contacts the guide seat 85 and, guided by the inclined surface of the guide seat 85, moves closer to the double-rail gear disk 82. After approaching, the drive gear plate 84 remains in a state of being driven to rotate by the double-rail gear disk 82, and in this state, contacts the gear ring 74, achieving the effect of synchronously driving the gear ring 74 to rotate. Since the position of the guide seat 85 is fixed, as the rotation angle of the double-rail gear disk 82 increases... The drive toothed plate 84 disengages from the guide seat 85 and is reset by a spring. After reset, the drive toothed plate 84 moves away from the transmission range of the gear ring 74. That is, the drive toothed plate 84 will only be compressed and moved into the transmission range of the gear ring 74 and transmit power when it rotates to the guide seat 85. The angle of the transmission gear ring 74 is the same as the arc value of a single convex filter plate 73. Thus, when the drive toothed plate 84 rotates one revolution, the fixed ring head 71 on the drive gear ring 74 rotates one unit angle of the convex filter plate 73. The fixed ring head 71 drives multiple convex filter plates 73 to rotate via multiple arrays of guide baffles 72. Each convex filter plate 73 replaces the previous convex filter plate 73, achieving the effect of convex filter plate replacement. By setting multiple circular arrays of convex filter plates 73 to rotate intermittently, the filtration range is continuously changed, greatly increasing the filtration area. This transmission also enables the cleaning, separation, and collection of dust and metal particles from different areas of the convex filter plates 73. Furthermore, when the drive toothed plate 84 is driven on the guide seat 85, the toothless areas on the dust shaking toothed disc 821 and the metal particle shaking toothed disc 822 correspond to the two shaking components 9, respectively. In this state, the double-rail toothed disc 82 does not drive the two shaking components 9 to move.

[0039] When the drive toothed plate 84 disengages from the guide seat 85, the double-rail toothed disc 82 meshes with the gears 92 in the two shaking components 9 through the toothed areas of the dust shaking toothed disc 821 and the metal powder shaking toothed disc 822, respectively. The gears 92 drive the shaking rods 93 to rotate through the connecting shaft 91. During rotation, the shaking rods 93 in the two shaking components 9 continuously strike the convex filter plate 73 in that area. When the shaking component 9 in the magnetic zone strikes the convex filter plate 73, the convex filter plate 73 is subjected to force and shakes due to the spring force. During the shaking, the filtered impurities are shaken. Since the convex filter plate 73 in this position is in the magnetic zone, the metal powder in the impurities will be continuously adsorbed onto the convex filter plate 73 due to the magnetic force during the shaking. The 73 can only shake and feed dust. The dust is fed into the dust collection base 11 by the shaking force, realizing the separation of dust and metal powder. After separation, the convex filter plate 73 containing only metal powder continues to rotate. When it rotates to the non-magnetic zone, some metal powder will fall into the metal powder collection base 12 by gravity for collection. When the shaking component 9 rotates in the non-magnetic zone, it is shaken by the shaking component 9, realizing the effect of the convex filter plate 73 feeding and collecting metal powder alone. This solves the problem that the existing dust collector cannot separate and recycle dust and metal powder. At the same time, the convex filter plate 73 realizes the moving filtration, dust screening and metal powder collection in sequence during continuous rotation, further achieving the effect of cyclic filtration and recycling.
