Abstract
Description
Technical Field
[0001] This utility model relates to the field of sintering flux recovery technology, specifically to a sintering flux recovery device. Background Technology
[0002] When welding metals using sintered flux, the flux is typically sprayed onto the welding site. The flux melts to form slag and gas, which protect the molten pool and provide metallurgical benefits. However, some of the sintered flux easily falls to the ground during spraying, often containing a significant amount of dust and welding slag during recycling, requiring screening by a recycling system.
[0003] CN211102288U discloses a sintering flux recovery device, which removes larger-sized welding slag and other impurities by screening through a sieve plate. The sintering flux after screening falls onto a first guide plate. When the sintering flux on the first guide plate accumulates to a preset amount, the baffle at the discharge port is opened, and the first guide plate is shaken by a vibration mechanism, so that the flux slides down the first guide plate into the recovery bag at the discharge port, thus removing larger-sized welding slag and other impurities.
[0004] However, the flux to be screened usually contains dust particles with small diameters. The dust passes through the screen plate along with the flux and falls onto the first guide plate. Finally, it slides along the first guide plate towards the discharge port with the screened flux. Since the dust is light, it is easy to drift and overflow from the discharge port, affecting the air quality of the factory. Utility Model Content
[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a sintering flux recovery device to solve the technical problem that the flux to be screened in the prior art usually contains dust with small particle size. The dust will pass through the screen plate at the same time as the flux and fall onto the first guide plate. Finally, it will slide along the first guide plate to the discharge port with the screened flux. Since the dust is light, it is easy to drift and overflow from the discharge port, affecting the air quality of the factory.
[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:
[0007] This utility model provides a sintering flux recovery device, comprising:
[0008] The recycling bin has an inlet and an outlet located below the inlet;
[0009] The screening assembly includes a slag screen and a dust screen disposed within the recycling bin. The slag screen is located above the dust screen and is used to intercept welding slag and allow flux to pass through. The dust screen is used to intercept flux and allow dust to pass through. The dust screen, the slag screen, and the inner wall of the recycling bin together form a receiving cavity, which is connected to the discharge port.
[0010] A dust collection assembly, wherein the dust collection port of the dust collection assembly is connected to the recycling bin, and the connection point is located below the dust sieve.
[0011] In one embodiment, the dust collection assembly includes a magnetic suction part disposed inside the recycling bin and located below the dust sieve.
[0012] In one embodiment, the recycling bin further has a mounting port communicating with the outside and its internal cavity, the mounting port being located below the dust sieve;
[0013] The dust collection assembly also includes a dust hopper, the upper opening of which forms the dust suction port and can enter the recycling bin through the installation port, and is placed below the dust sieve. The magnetic suction part is installed in the dust hopper.
[0014] In one embodiment, the bottom of the dust hopper is provided with a slot, which is located on the outside of the dust hopper;
[0015] The magnetic suction part is engaged in the slot.
[0016] In one embodiment, the recycling bin further has a slag discharge port communicating with the outside and its inner cavity, the slag discharge port being located above the discharge port;
[0017] The welding slag screen is inclined downwards along the direction close to the discharge port, and its lower end is at the same horizontal plane as the slag discharge port.
[0018] In one embodiment, the sintering flux recovery device further includes a vibration component, which is located in the recovery box and connected to the dust screen and the slag screen, and can synchronously drive the slag screen and the dust screen to vibrate.
[0019] In one embodiment, the lower ends of the welding slag screen and the dust screen are respectively rotatably installed on the inner wall of the recycling box;
[0020] The vibration assembly includes a cam, a connecting arm, and a drive unit. The cam is rotatably installed inside the recycling bin and located below the welding slag screen or the dust screen. When rotating, it can press against the welding slag screen or the dust screen to rotate. The two ends of the connecting arm are rotatably connected to the welding slag screen and the dust screen, respectively. The drive unit is connected to the cam and is used to drive the cam to rotate.
[0021] In one embodiment, the drive unit includes a drive shaft and a drive motor. The drive shaft is rotatably mounted on the recycling bin and has an installation section located inside the recycling bin and below the welding slag screen or the dust screen, and a transmission section extending out of the recycling bin. The drive motor is located outside the recycling bin, and its output shaft is connected to the transmission section.
[0022] The cam is mounted on the mounting section.
[0023] In one embodiment, the welding slag screen is provided in multiple ways, and the inner diameter of the screen holes of the multiple welding slag screens is different. They can be selectively installed in the recycling box, and each welding slag screen can be detachably installed in the recycling box.
[0024] In one embodiment, the sintering flux recovery device further includes rollers located at the bottom of the recovery box.
[0025] Compared with existing technologies, the sintering flux recovery device provided by this utility model involves feeding the flux to be screened into the recovery box through the inlet. During its descent, the flux first falls onto a slag screen, which intercepts larger particles of slag and other impurities, while the flux and dust pass through and fall onto a dust screen. The dust screen then intercepts the flux and allows dust to pass through. As the dust passes through the dust screen and descends, it is absorbed by a dust collection component, preventing it from scattering and overflowing from the outlet. Simultaneously, the flux intercepted by the dust screen can be removed from the outlet and collected in a collection component outside the outlet. Thus, because the dust has already passed through the dust screen and been absorbed by the dust collection component, the flux recovery process prevents dust from drifting into the factory, improving the factory's air quality.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0035] To address the technical problem that the flux to be screened often contains small dust particles, which pass through the sieve plate along with the flux and fall onto the first guide plate, eventually sliding along the first guide plate towards the discharge port with the screened flux, and that the dust, being light, easily drifts out of the discharge port, affecting the air quality of the factory, this invention provides a sintering flux recovery device. The dust has already passed through the dust sieve and been adsorbed by the dust collection component, so that the flux sliding down for recovery will not cause dust to drift into the factory, thus improving the air quality of the factory.
[0036] Please see Figures 1 to 3 , Figures 1 to 3 This is a schematic diagram of the sintering flux recovery device in one embodiment of the present invention. The sintering flux recovery device includes a recovery box 1, a screening component, and a dust collection component 4. The recovery box 1 has an inlet 1a and an outlet 1b located below the inlet 1a. The screening component includes a slag screen 2 and a dust screen 3 disposed in the recovery box 1. The slag screen 2 is located above the dust screen 3 and is used to intercept slag and allow flux to pass through. The dust screen 3 is used to intercept flux and allow dust to pass through. The dust screen 3, the slag screen 2, and the inner wall of the recovery box 1 together form a receiving cavity, which is connected to the outlet 1b. The dust collection port of the dust collection component 4 is connected to the recovery box 1, and the connection point is located below the dust screen 3.
[0037] In the sintering flux recovery device provided by this utility model, the flux to be screened is fed into the recovery box 1 through the inlet 1a. During its descent, it first falls onto the slag screen 2, where it intercepts larger particles of slag and other impurities. The flux and dust, however, pass through the slag screen 2 and fall onto the dust screen 3. The dust screen 3 then intercepts the flux and allows dust to pass through. As the dust passes through the dust screen 3 and descends, it is absorbed by the dust collection component 4, preventing it from scattering and overflowing from the outlet 1b. Simultaneously, the flux intercepted by the dust screen 3 can be removed from the outlet 1b and collected in a recovery bag outside the outlet 1b. Thus, since the dust has already passed through the dust screen 3 and been absorbed by the dust collection component 4, the flux recovery process prevents dust from scattering into the factory, improving the factory's air quality.
[0038] Furthermore, as the feed inlet 1a continues to feed, the dust screen 3 simultaneously and continuously passes through the dust, causing the screened flux to slide down to the outlet 1b, thus preventing the flux from accumulating on the dust screen 3, ensuring that the dust and flux can be continuously and effectively separated, and improving the flux screening effect.
[0039] Specifically, in this solution, the dust sieve 3 is inclined downwards along the direction close to the discharge port 1b, and its lower end is at the same horizontal plane as the discharge port 1b; the dust collection component 4 is located inside the recycling bin 1 and below the dust sieve 3, and is used to absorb dust. In this way, the flux intercepted by the dust sieve 3 can slide along the inclined direction of the dust sieve 3 towards the discharge port 1b, and finally be collected in the recycling bag outside the discharge port 1b.
[0040] It should be understood that the inner diameter of the sieve opening of the slag sieve 2 is smaller than the particle size of the slag and larger than the particle size of the flux; while the inner diameter of the sieve opening of the dust sieve 3 is smaller than the particle size of the flux and larger than the particle size of the dust.
[0041] It should be noted that the dust collection component can be an adsorption gel, an electrostatic adsorption device, or other forms. It should also be understood that in some cases, the content of iron, cobalt, and nickel in certain fluxes is relatively high, resulting in a high proportion of iron, cobalt, and nickel in the weld slag debris. Weld slag debris is the main component of dust in welding workshops.
[0042] Therefore, in one embodiment, please refer to Figure 3 and Figure 4 The dust collection assembly 4 also includes a magnetic suction part 41, which is located inside the collection bin 1 and below the dust sieve 3.
[0043] In this embodiment, a magnetic suction unit 41 is provided below the dust sieve 3. The magnetic suction unit 41 adsorbs welding slag and debris in the dust, preventing dust from being stirred up by material impact and improving the air quality in the factory. Moreover, the magnetic suction unit 41 can be reused and does not consume energy, saving costs.
[0044] In one embodiment, the recycling bin 1 also has an installation port 1c that connects the outside to its inner cavity, and the installation port 1c is located below the dust sieve 3; the dust collection assembly 4 also includes a dust hopper 5, the upper opening of the dust hopper 5 forms a dust collection port, and can enter the recycling bin 1 through the installation port 1c, and is located below the dust sieve 3, and the magnetic suction part 41 is installed on the dust hopper 5.
[0045] In this embodiment, the magnetic suction part 41 attracts dust into the dust hopper 5, allowing the dust hopper 5 to be periodically removed from the recycling bin 1 for cleaning via the mounting port 1c, thus improving convenience. It should be noted that, for added convenience, a handle is provided on the side of the dust hopper 5 extending beyond the mounting port 1c.
[0046] It should be noted that the magnetic attraction part 41 can be configured as a magnetic clasp, a magnetic strip, or a magnetic coating, or other forms. Specifically, in this embodiment, the magnetic attraction part 41 is configured as a magnetic strip.
[0047] In one embodiment, the bottom of the dust hopper 5 is provided with a slot 5a, which is located on the outside of the dust hopper 5; the magnetic part 41 is engaged in the slot 5a.
[0048] In this embodiment, the magnetic suction part 41 is engaged in the slot 5a on the outer side of the bottom of the dust hopper 5, so that when cleaning the dust in the dust hopper 5, the magnetic suction part 41 can be controlled to disengage from the slot 5a of the dust hopper 5, eliminating the magnetic attraction, and then the dust in the dust hopper 5 can be poured out, further improving convenience.
[0049] Specifically, in this embodiment, there are three card slots 5a arranged horizontally at intervals, and correspondingly, there are three magnetic strips, which are respectively locked in the three card slots 5a.
[0050] In one embodiment, the recycling bin 1 also has a slag discharge port 1d that connects the outside to its inner cavity, and the slag discharge port 1d is located above the discharge port 1b; the welding slag screen 2 is inclined downward along the direction close to the discharge port 1b, and its lower end is at the same horizontal plane as the slag discharge port 1d.
[0051] In this embodiment, the welding slag screen 2 is also inclined as above, so that when the flux to be separated is fed into the recycling box 1, the flux to be separated is sent from the feed port 1a to the upper end of the welding slag screen 2, so that the flux to be separated slides down along the inclined direction of the welding slag screen 2, and the intercepted welding slag can be directly discharged from the slag discharge port 1d, without the need for manual cleaning of the welding slag on the welding slag screen 2 regularly, thus improving convenience.
[0052] In one embodiment, please refer to Figure 2 and Figure 5The sintering flux recovery device also includes a vibration component 6, which is located in the recovery box 1 and connected to the dust screen 3 and the slag screen 2, and can synchronously drive the slag screen 2 and the dust screen 3 to vibrate.
[0053] In this embodiment, the vibration component 6 can strike the dust screen 3 and the welding slag screen 2 to prevent material from getting stuck on the dust screen 3 and the welding slag screen 2, and at the same time, it can speed up the passage of materials through the corresponding screens and improve the screening efficiency.
[0054] It should be noted that the vibration component 6 can be configured as two independent vibrating hammers or hydraulic push rods, or other forms. Furthermore, in this embodiment, baffles can be installed at the slag discharge port 1d and the discharge port 1b. These baffles are movable via a linear motor or hydraulic cylinder, and can open and close their respective openings during movement. When the material at the baffle location accumulates to a certain amount, the vibration component 6 can vibrate the screen, causing the material to pass through the screen, thereby improving screening efficiency.
[0055] In one embodiment, the lower ends of the slag screen 2 and the dust screen 3 are rotatably mounted on the inner wall of the recycling bin 1, respectively; the vibration assembly 6 includes a cam 61, a connecting arm 62 and a drive part 63. The cam 61 is rotatably mounted in the recycling bin 1 and is located below the slag screen 2 or the dust screen 3. When rotating, it can press against the slag screen 2 or the dust screen 3 to rotate. The two ends of the connecting arm 62 are rotatably connected to the slag screen 2 and the dust screen 3, respectively. The drive part 63 is connected to the cam 61 and is used to drive the cam 61 to rotate.
[0056] In this embodiment, the drive unit 63 drives the cam 61 to rotate, and the cam 61 can drive the welding slag screen 2 or the dust screen 3 to rotate during the rotation. When one of the welding slag screen 2 or the dust screen 3 rotates, it can drive the other to rotate via the connecting arm 62, thereby improving transmission efficiency and reducing the number of drive devices and saving costs.
[0057] In one embodiment, the drive unit 63 includes a drive shaft 631 and a drive motor. The drive shaft 631 is rotatably mounted on the recycling bin 1. It has an installation section located inside the recycling bin 1 and below the welding slag screen 2 or dust screen 3, and a transmission section extending out of the recycling bin 1. The drive motor is located outside the recycling bin 1, and its output shaft is connected to the transmission section. The cam 61 is mounted on the installation section.
[0058] In this embodiment, the drive motor is installed outside the recycling bin 1 and driven by the drive shaft 631, which avoids the drive motor being affected by dust if it is installed inside the recycling bin 1, thus extending the service life of the drive motor.
[0059] In one embodiment, there are multiple types of welding slag screens 2, each with a different inner diameter of the screen hole, and each welding slag screen 2 can be selectively installed in the recycling bin 1. Each welding slag screen 2 can be detachably installed in the recycling bin 1.
[0060] In this embodiment, welding slag sieves 2 with multiple aperture sizes are provided, allowing selection based on the particle size of the flux and improving versatility. It should be understood that, since the particle size of dust differs significantly from that of flux, the sieve apertures of the dust sieve 3 can be directly set to a smaller aperture to meet the requirements of fluxes with various particle sizes.
[0061] Based on the embodiments of the cam 61 and connecting arm 62 described above, please refer to... Figure 5 and Figure 6 The connecting arm 62 is rotatably connected to one end of the welding slag screen 2. That is, the upper end of the connecting arm 62 is provided with a connecting arm 62 that cooperates with the welding slag screen 2. The upper side of the connecting arm 62 is provided with a clearance hole 62b. The welding slag screen 2 is provided with a rotating shaft 21 corresponding to the connecting arm 62. The rotating shaft 21 of the welding slag screen 2 is detachably engaged in the connecting arm 62 through the clearance hole 62b.
[0062] In addition, the corresponding rotatable connection between the recycling box 1 and the welding slag screen 2 is provided with mounting screw holes 1e. The screening assembly also includes mounting bolts 7, which have threaded sections 71 and rotating sections 72 connected to each other. The threaded section 71 is screwed into the mounting screw hole 1e, while the rotating section 72 extends into the inner cavity of the recycling box 1 and is not threaded, and is rotatably connected to the welding slag screen 2.
[0063] In one embodiment, the sintering flux recovery device further includes a roller 8, which is located at the bottom of the recovery box 1.
[0064] In this embodiment, rollers 8 are provided at the bottom of the recycling bin 1 to facilitate flexible movement of the recycling device and improve convenience.
[0065] To better understand this utility model, the following is combined with... Figures 1 to 6 The technical solution of this utility model is described in detail below:
[0066] The flux to be screened is fed into the recovery box 1 through the inlet 1a. During its descent, it first falls onto the slag screen 2, where it intercepts larger particles of slag and other impurities. The flux and dust pass through the slag screen 2 and fall onto the dust screen 3. The dust screen 3 then intercepts the flux and allows the dust to pass through. The flux intercepted by the dust screen 3 slides along the inclined direction of the dust screen 3 towards the outlet 1b and is finally collected in the collection component outside the return port. The dust falls below the dust screen 3 and is magnetically attracted by the magnetic strip at the bottom of the dust hopper 5, preventing the dust from being scattered due to vibration. During the screening process, the drive motor drives the drive shaft 631 to rotate, which in turn drives the cam 61 to rotate, allowing the dust screen 3 and the slag screen 2 to vibrate synchronously, improving screening efficiency.
[0067] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
