Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dust recovery, in particular to a metal dust recovery device for section steel processing. BACKGROUND

[0002] The most common cross-sectional shape of section steel is "H" shape. During section steel welding processing, submerged arc welding process is generally used. Due to the characteristics of submerged arc welding process itself, the strength of section steel after welding can be ensured.

[0003] During submerged arc welding operation, the part to be welded of section steel is covered by a layer of granular flux. At this time, the continuously fed welding wire ignites the arc between the welding piece below the flux layer. The high temperature generated by the arc melts the welding wire, the workpiece and the flux, thereby forming a metal molten pool, and at the same time, the molten slag behind the molten pool begins to cool and solidify, and finally forms a slag shell; the granular flux accumulated above the molten pool is recycled.

[0004] However, during the welding process, the residual metal slag on the outer end of the section steel and the welding slag are recycled together with the granular flux, which affects the reuse of the recycled flux, which is relatively inconvenient.

The flux feeding pipe 2, the submerged arc welding machine body 4, and the sealed recovery pipe 5 are sequentially and fixedly installed at the upper end of the fixed frame 6 from back to front; The metal dust separation mechanism 9 is provided with a separation type flux recovery mechanism 8 for recovering the flux remaining on the profile steel after the welding by the submerged arc welding machine body 4 and separating the small impurities; The inner end middle part of the stand 7 is provided with a metal dust separation mechanism 9 for separating and recovering the metal impurities in the flux screened by the separation type flux recovery mechanism 8; As shown in Figure 1 and Figure 4 The metal dust separation mechanism 9 comprises a separation box 91, a hopper 92, a belt conveyor 93 and an adsorption and distribution assembly; the separation box 91 is fixedly installed at the inner end middle part of the stand 7;

The upper end front side inlet of the separation box 91 is fixedly installed with the hopper 92; The adsorption and distribution assembly is symmetrically installed at the left and right ends of the separation box 91; The flux storage bin 3 is fixedly installed at the lower end rear side of the separation box 91; the outlet of the separation box 91 is communicated with the flux storage bin 3; The flux feeding pipe 2 is communicated with the outlet of the flux storage bin 3 through a connecting pipe; The side end of the flux storage bin 3 is rotatably installed with a seal cover capable of being turned open; The flux storage bin 3 is filled with flux; The outlet position of the flux storage bin 3 is also fixedly installed with an electric control valve; The separation type flux recovery mechanism 8 is installed at the upper end of the separation box 91; The upper end front side of the base plate 1 is also symmetrically installed with a slag decomposition and recovery mechanism 10 for moving and recovering the slag on the profile steel; In the present application, the profile steel needing welding operation enters from the rear of the base plate 1 and moves forward by the conveying device; when the welding position of the profile steel moves to the position where the flux feeding pipe 2 is located, the electric control valve of the outlet of the flux storage bin 3 works, the blockage of the outlet of the flux storage bin 3 is removed, and then the flux in the flux storage bin 3 is continuously discharged to the welding position of the profile steel through the flux feeding pipe 2; Then the profile steel continues to move forward, and in the moving process, the submerged arc welding machine body 4 works and cooperates with the flux to perform the submerged arc welding operation on the welding position of the profile steel; With the continuous forward movement of the profile steel, the separation type flux recovery mechanism 8 works to suck away the flux remaining on the welding position of the profile steel through the seal recovery pipe 5, and the separation type flux recovery mechanism 8 also screens the small dust and impurities in the flux from the flux, and moves the flux after screening the impurities into the hopper 92;

When the sealing recovery pipe 5 sucks away the flux remaining on the profile steel welding part, the welding slag at the profile steel welding seam is exposed; as the profile steel moves forward, the welding slag gradually cools down;

Finally, the profile steel after welding is removed from the front of the base plate 1 to the next processing procedure.

[0015] In some embodiments, as shown in Figures 3-7 As a preferred embodiment of the present application, the separation type flux recovery mechanism 8 includes a screening cylinder 81, a screening motor 82, a rotating shaft 83, stirring blades 84, a filter screen plate 85, first buffer springs 86, a fixed ring 87, a discharge chute 88, a first discharge inclined plate 89 and a baffle 810; the screening cylinder 81 is fixedly installed on the front side of the upper end of the separation box 91; the screening motor 82 is fixedly installed on the upper end of the screening cylinder 81; the upper end of the rotating shaft 83 is rotatably installed on the inner top of the screening cylinder 81; the output end of the screening motor 82 is fixedly connected with the rotating shaft 83; The lower side of the outer end of the rotating shaft 83 is fixedly installed with a plurality of stirring blades 84; and the stirring blades 84 are uniformly distributed at equal intervals in a circle on the outer end of the rotating shaft 83; The middle part of the screening cylinder 81 is fixedly installed with the fixed ring 87; the lower end of the plurality of first buffer springs 86 is fixedly connected with the upper end of the fixed ring 87; the upper end of the first buffer spring 86 is fixedly connected with the lower end of the filter screen plate 85; And the stirring blades 84 are slidingly connected with the upper end of the filter screen plate 85; The front side of the filter screen plate 85 is provided with the discharge chute 88; The front lower side of the screening cylinder 81 is provided with a displacement slot 811; the first discharge inclined plate 89 is fixedly installed on the front side of the fixed ring 87 through a support; and the upper end of the first discharge inclined plate 89 is further fixedly installed with the baffle 810; The outer end upper side of the screening cylinder 81 is fixedly provided with a blower, so that negative pressure is generated in the interior of the screening cylinder 81. The screening cylinder 81 is communicated with the sealing recovery pipe 5 through a corrugated pipe. The lower side of the side end of the screening cylinder 81 is also rotatably provided with a sealing cover capable of being turned open. As shown in Figure 3 and Figure 4 The adsorption and distribution assembly comprises a power-off type magnetic block 95, an adsorption plate 96, a cross plate 97, a push cylinder 98, a second discharge inclined plate 99, a recovery box 910, a support frame plate 911, a guide rail 912 and a sliding block 913; two ends of the separation box 91 are symmetrically provided with a clearance slot 94 in sliding connection with the adsorption plate 96. As shown in Figure 4 The height of the adsorption plate 96 is half of the clearance slot 94, so that when the adsorption plate 96 moves outward, the metal substances attached to the adsorption plate 96 will not be scraped off by the side wall of the clearance slot 94; and the bottom of the adsorption plate 96 is flush with the middle part of the clearance slot 94. The far ends of the two adsorption plates 96 are fixedly provided with the power-off type magnetic blocks 95; the cross plate 97 is fixedly installed on the outer wall of the separation box 91; the push cylinder 98 is fixedly installed on the cross plate 97, and the output end of the push cylinder 98 is fixedly connected with the adsorption plate 96; and the second discharge inclined plate 99 is fixedly installed on the outer wall of the separation box 91.

The recovery box 910 is detachably installed on the lower side of the stand 7. In the present application, the blower installed on the screening cylinder 81 works, so that negative pressure is generated in the interior of the screening cylinder 81, the sealing recovery pipe 5 sucks the residual flux on the welded part of the section steel into the interior of the screening cylinder 81, then the screening cylinder 81 falls down to the upper end of the filter screen plate 85, and the tiny impurities attached to the flux will fall to the inner bottom of the screening cylinder 81 through the filter holes on the filter screen plate 85. At this time, the filter screen plate 85 will also compress the first buffer spring 86, so as to reduce the impact force when the flux falls, and the service life of the device is improved. Then the screening motor 82 works to drive the rotating shaft 83 and the stirring blade 84 to rotate, the stirring blade 84 will drive the flux accumulated on the filter screen plate 85 to rotate, so that the flux moves to the position where the discharge chute 88 is located, then the flux will fall to the first discharge inclined plate 89 through the discharge chute 88, and finally move downward along the first discharge inclined plate 89 to the hopper 92. The flux after the separation of the small impurities falls through the hopper 92 to the upper end of the belt conveyor 93 in the separation box 91; the belt conveyor 93 works to drive the flux to move backward, when it moves to the vicinity of the adsorption plate 96, the metal substances in the flux are attracted to the lower end of the inside of the adsorption plate 96 by the de-energized magnetic block 95 with magnetic force, and the welding body continues to move with the belt conveyor 93 and enters the inside of the flux storage bin 3 through the feeding port at the lower rear side of the separation box 91; When the welding work of a group of section steels is completed, the push cylinder 98 works to pull the adsorption plate 96 to drive the de-energized magnetic block 95 to move outward along the guide rail 912 with the sliding block 913 until the adsorption plate 96 is moved out of the accommodation groove 94 and is located between the front and rear ends of the second discharge inclined plate 99; Then the de-energized magnetic block 95 is energized to break the magnetism, and then the metal substances on the adsorption plate 96 fall onto the second discharge inclined plate 99 and slide downward along the second discharge inclined plate 99 into the recovery box 910.

[0016] In some embodiments, as shown in Figure 6 and Figure 8 illustrated, as a preferred embodiment of the present application, the slag decomposition and recovery mechanism 10 includes a placing rack 101, a scraping plate 102, a fixed cylinder 103, a driving motor 104, a driving crank 105, a push rod 106, a movable arm 107, a counterweight 108, a second buffer spring 1010 and a suction gun 1011; the placing rack 101 is fixedly installed on the upper end of the front side of the base plate 1; the scraping plates 102 inclined rearward are fixedly installed on the front side of the close end of the left and right two placing racks 101; The fixed cylinder 103 is fixedly installed on the middle part of the inner end of the placing rack 101 through a support frame; The driving motor 104 is fixedly installed on the upper side of the far end of the left and right two fixed cylinders 103; The upper end of the driving crank 105 is rotatably installed on the inner wall of the fixed cylinder 103; the output end of the driving motor 104 is fixedly connected with the upper end of the driving crank 105; The lower end of the push rod 106 is hingedly connected with the upper end of the movable arm 107; The lower end of the push rod 106 is hingedly connected with the upper end of the movable arm 107; The lower end of the movable arm 107 is fixedly connected with the upper end of the counterweight 108; the lower side inner wall of the fixed cylinder 103 is provided with a sliding groove 109; the counterweight 108 is limitingly and slidably connected with the sliding groove 109; The upper end of the second buffer spring 1010 is fixedly connected with the middle part of the inner wall of the fixed cylinder 103; the lower end of the second buffer spring 1010 is fixedly connected with the upper end of the counterweight 108; The suction gun 1011 is fixedly installed at the rear end of the rack 101, and is communicated with the industrial dust collector through an air pipe; In the present application, when the profile steel moves to the position of the slag decomposing and recycling mechanism 10, the scraping plate 102 is inserted between the weld and the slag exposed outside the weld. As the profile steel continues to move forward, the scraping plate 102 will shovel the slag off the profile steel, and the shoveling slag will be blocked by the rear end of the scraping plate 102. Then, the driving motor 104 works to drive the driving crank 105 to rotate, which drives the push rod 106 to move up and down continuously. When the push rod 106 moves downward, it will push the movable arm 107 to drive the counterweight 108 to move downward along the chute 109. At this time, the counterweight 108 will crush the slag. When the push rod 106 moves upward, the counterweight 108 will be reset upward under the restoring force of the second buffer spring 1010. Through the up-and-down reciprocating movement of the push rod 106, the continuous crushing operation of the counterweight 108 on the slag can be realized. When the slag is crushed by the counterweight 108, the industrial dust collector connected with the suction gun 1011 will work, and the crushed slag will be recycled from the profile steel through the suction gun 1011.
