Description

Technical Field

[0001] The present invention relates to the technical field of dust treatment, and specifically to a dust collection device for treating rare earth oxides. Background Art

[0002] Rare earth oxides refer to compounds formed by the reaction of rare earth elements with oxygen, such as cerium oxide, lanthanum oxide, neodymium oxide, and samarium oxide. Due to the good electrical conductivity and thermal conductivity of rare earth oxides, they are widely used in fields such as catalysts, glass, and ceramics. During the treatment process of rare earth oxides, especially in the drying and grinding stages, a large amount of dust may be generated. Considering the relatively scarce resources of rare earth elements, these dusts may contain unutilized rare earth oxides. Therefore, by effectively collecting and reprocessing these dusts, the recycling of resources can be achieved. Currently, bag dust removal devices are usually used for dust.

[0003] A Chinese invention patent with the publication number CN119280993B discloses a dust collection device for treating rare earth oxides, including a mounting frame. A treatment box is fixedly connected to the mounting frame. A feed pipe is communicated with one side of the treatment box. A discharge pipe is communicated with the lower part of the treatment box. A plurality of cloth bags are distributed inside the treatment box. A plurality of movable covers are evenly distributed and detachably connected to the upper part of the treatment box. A first fixed cover is fixedly connected to the middle of the movable cover. A second fixed cover is arranged directly below the first fixed cover. A first rotating shaft is rotatably connected between the first fixed cover and the second fixed cover. A clamping component for clamping the opening of the cloth bag is arranged on the movable cover. The invention is provided with components such as an agitation component. By continuously touching the inner wall of the cloth bag with the agitation block, the cloth bag is caused to vibrate, so that the dust on the outer wall of the cloth bag can be shaken off. In this way, the dust on the outer wall of the cloth bag can be effectively collected, the outer wall of the cloth bag is kept clean, the air circulation is maintained, and the dust removal efficiency of the cloth bag is ensured.

[0004] However, the above patent still has the following deficiencies in actual use: The patent can monitor the air flow in all air inlet pipes through a flow monitoring valve to judge whether there is dust with strong adhesiveness on the outer wall of the cloth bag. If the cloth bag needs to be cleaned, the cleaning operations of all cloth bags are carried out synchronously. However, not all the outer walls of the cloth bags are contaminated with dust with strong adhesiveness. Synchronously cleaning all cloth bags invisibly causes waste of resources. Moreover, the patent uses a first synchronous belt component to drive the lead screw to rotate. A window for the first synchronous belt component to pass through needs to be opened on the connecting seat. Otherwise, the first synchronous belt component cannot work. There must be a gap between the first synchronous belt component and the inner wall of the window, and air will overflow from this gap, which will affect the monitoring effect of the flow monitoring valve, that is, the flow monitoring valve often makes misjudgments, and these misjudgments result in ineffective cleaning operations on the cloth bags.

The driving mechanism 9 can drive the lifting mechanism 7 to work, and the lifting mechanism 7 can drive the agitation mechanism 8 to agitate the single cloth bag 3. The driving mechanism 9 can also selectively drive the scraping and brushing mechanism 6 to scrape and brush the outer wall of the cloth bag 3, so that the dust with strong stickiness on the cloth bag 3 can be scraped off, avoiding ineffective cleaning operations on the cloth bag 3.

[0024] It is worth noting that the clamping component 11 is a prior art, which includes an electromagnet and an elastic member.

The top end of the cloth bag 3 is fixedly clamped by the clamping component 11 on the fixed top ring 54, and the bottom end of the cloth bag 3 is clamped by the clamping component 11 on the fixed bottom ring 43.

[0025] When the present invention is in operation, the cloth bag 3 can be agitated through the cooperation among the agitation mechanism 8, the drive mechanism 9 and the lifting mechanism 7. The agitation mechanism 8 includes a plurality of arc-shaped abutting plates 81 and an agitation disk body 82. A sliding hole 821 that is slidably matched with the guiding shaft 12 is provided at the center of the agitation disk body 82. A plurality of air vents 822 that are arranged at equal angles along the circumferential direction thereof are formed in the agitation disk body 82. A plurality of built-in grooves 823 that are arranged at equal angles along the circumferential direction thereof are formed in the inner wall of the agitation disk body 82. The built-in grooves 823 are located between two adjacent air vents 822. An outward extension component 83 for driving the arc-shaped abutting plate 81 to always abut against the inner wall of the cloth bag 3 is provided in the built-in groove 823. The agitation disk body 82 is arranged on the lifting mechanism 7, and all the arc-shaped abutting plates 81 are respectively arranged on all the outward extension components 83.

[0026] The outward extension component 83 includes a linkage gear 831, an upward movement rod 832, a downward movement rod 833 and a plurality of groups of transmission block groups. A plurality of upper tooth grooves 8321 are provided at the bottom of the upward movement rod 832. A plurality of lower tooth grooves 8331 are provided at the top of the downward movement rod 833. Slide bars 834 are provided on the outer walls of the upward movement rod 832 and the downward movement rod 833. A spring 835 is provided at the head end of the downward movement rod 833. A convex block 836 is provided at the tail end of the downward movement rod 833. A first wedge surface 8361 is provided at the tail end of the convex block 836. A plurality of notches 824 for the head end of the upward movement rod 832 to pass through are formed in the outer wall of the agitation disk body 82. The notches 824 communicate with the built-in groove 823. Each transmission block group includes a plurality of transmission blocks 837 that are arranged at equal angles along the circumferential direction of the guiding shaft 12 on the outer wall of the guiding shaft 12. A second wedge surface 8371 that is matched with the first wedge surface 8361 is provided at the head end of the transmission block 837. Two sliding seats 8231 that are matched with the slide bars 834 are provided on both side walls of the built-in groove 823. The linkage gear 831 is rotatably arranged in the built-in groove 823. The upward movement rod 832 and the downward movement rod 833 are respectively located above and below the linkage gear 831. The upper tooth grooves 8321 and the lower tooth grooves 8331 are both meshed with the linkage gear 831. One end of the spring 835 abuts against the groove wall of the built-in groove 823. The outer wall of the tail end of the convex block 836 is slidably matched with the outer wall of the guiding shaft 12. All the transmission block groups are arranged at equal intervals along the height direction of the guiding shaft 12.

[0027] The driving mechanism 9 and the lifting mechanism 7 can drive the agitation disk body 82 to move downward. Due to the elastic force of the spring 835, the arc-shaped abutting plate 81 abuts against the inner wall of the cloth bag 3. All the arc-shaped abutting plates 81 can support and abut against the entire cloth bag 3. During the downward movement of the agitation disk body 82, the convex block 836 moves downward synchronously with the agitation disk body 82, and the first wedge surface 8361 on the convex block 836 gradually abuts against the second wedge surface 8371 on the transmission block 837. Then, due to the cooperation of the first wedge surface 8361 and the second wedge surface 8371, the convex block 836 is driven to move into the built-in groove 823. The convex block 836 drives the downward movement rod 833 to move synchronously. The spring 835 is compressed. The downward movement rod 833 drives the linkage gear 831 to rotate through the lower tooth groove 8331. The linkage gear 831 drives the upward movement rod 832 to move through the upper tooth groove 8321. The upward movement rod 832 also gradually moves into the built-in groove 823 through the notch 824. The moving directions of the downward movement rod 833 and the upward movement rod 832 are opposite. The upward movement rod 832 drives the arc-shaped abutting plate 81 to move. The arc-shaped abutting plate 81 moves away from the inner wall of the cloth bag 3. Subsequently, the convex block 836 gradually disengages from the transmission block 837. The elastic force of the spring 835 can drive the downward movement rod 833 to move toward the direction of the guiding shaft 12. The upward movement rod 832 also moves toward the inner wall of the cloth bag 3 due to the drive of the linkage gear 831. Then, the arc-shaped abutting plate 81 is driven by the upward movement rod 832 to impact against the inner wall of the cloth bag 3. As the agitation disk body 82 moves downward, the arc-shaped abutting plate 81 can continuously agitate and strike the cloth bag 3. The dust on the outer wall of the cloth bag 3 can be gradually separated from the cloth bag 3 by this agitation and knocking force.

[0028] Of course, two first wedge surfaces 8361 and second wedge surfaces 8371 can be provided (not shown in the figure). The two first wedge surfaces 8361 and second wedge surfaces 8371 are symmetrically arranged up and down. In this way, the agitation disk body 82 can also perform agitation and knocking operations on the cloth bag 3 when moving upward.

[0029] When only a single first wedge surface 8361 and a single second wedge surface 8371 are used to achieve agitation and knocking, the agitation disk body 82 needs to avoid the transmission block 837 when moving upward. Therefore, a plurality of arc-shaped through grooves 825 for the transmission block 837 to pass through are provided on the inner wall of the agitation disk body 82. A deflection assembly 10 is provided at the bottom of the fixed bottom plate 4. The deflection assembly 10 includes a semi-gear 101 and a translation electric push rod 102. A linkage rack 103 is provided at the output end of the translation electric push rod 102. The guiding shaft 12 is rotatably arranged on the fixed top cover 53 and the fixed bottom plate 4. The semi-gear 101 is arranged at the bottom of the guiding shaft 12. The translation electric push rod 102 is arranged at the bottom of the fixed bottom plate 4. The linkage rack 103 meshes with the semi-gear 101.

[0030] The linkage rack 103 is driven to move by translating the push rod. The linkage rack 103 drives the half gear 101 to rotate. The half gear 101 drives the guiding shaft 12 to deflect by a certain angle. After that, the position of the transmission block 837 is staggered from the position of the convex block 836. When the drum disc body 82 moves up and down, the arc-shaped through groove 825 can allow the transmission block 837 to pass through.

[0031] Further, a compression chamber 8332 is provided in the downward moving rod 833. A piston 8333 is slidably provided in the compression chamber 8332. One end of the piston 8333 is provided with a pull rod 8334. One end of the pull rod 8334 penetrates through the outer wall of the head end of the downward moving rod 833, and one end of the pull rod 8334 abuts against the groove wall of the built-in groove 823. An intake pipe 8335 communicating with the compression chamber 8332 and an L-shaped outlet pipe 8336 communicating with the compression chamber 8332 are respectively provided on both side walls of the downward moving rod 833. An intake one-way valve is provided in the intake pipe 8335, and an outlet one-way valve is provided in the L-shaped outlet pipe 8336. An air connection head 811 is provided on the back of the arc-shaped abutting plate 81. A plurality of air jet holes 812 are provided in the front of the arc-shaped abutting plate 81. The air connection head 811 is communicated with the L-shaped outlet pipe 8336 through a hose.

[0032] When the convex block 836 moves into the built-in groove 823, the piston 8333 performs a squeezing operation in the compression chamber 8332. Due to the action of the intake one-way valve and the outlet one-way valve, the gas in the compression chamber 8332 can enter the arc-shaped abutting plate 81 through the L-shaped outlet pipe 8336, the hose, and the air connection head 811, and then is ejected from all the air jet holes 812. The ejected gas can not only assist in cleaning some of the dust with lower viscosity on the cloth bag 3, but also assist in cleaning some of the dust with higher viscosity on the cloth bag 3, that is, gas backflushing cleaning. After the first wedge surface 8361 and the second wedge surface 8371 are staggered, the elastic force of the spring 835 can drive the downward moving rod 833 to move in the reverse direction, and the piston 8333 performs a pulling operation in the compression chamber 8332. Due to the action of the intake one-way valve and the outlet one-way valve, external air enters the compression chamber 8332 through the intake pipe 8335.

[0033] The lifting mechanism 7 includes a first lead screw 71 and a first guide rod 72. A nut 73 is screwed on the first lead screw 71. A guide sleeve 74 is slidably provided on the first guide rod 72. The first lead screw 71 is rotatably arranged on the fixed top cover 53 and the fixed bottom plate 4.

The driving mechanism 9 is in transmission connection with the first lead screw 71.

[0034] The driving mechanism 9 can drive the first lead screw 71 to rotate. After that, through the cooperation among the nut 73, the first guide rod 72, and the guide sleeve 74, the drum disc body 82 can be stably lifted and lowered.

[0035] The driving mechanism 9 can also selectively drive the brush mechanism 6 to work synchronously with the lifting mechanism 7. The brush mechanism 6 includes a second lead screw 61, a second guide rod 62, and a brush ring 63. The brush ring 63 is provided with a screw hole for mating with the second lead screw 61 and a guide hole for mating with the second guide rod 62. Two supporting ears 45 are provided on the outer wall of the fixed bottom plate 4. A rotating hole is provided on one of the supporting ears 45. The second lead screw 61 is rotatably arranged on the fixed top cover 53 and the rotating hole. The second guide rod 62 is fixedly connected to the fixed top cover 53 and the other supporting ear 45. The inner wall of the brush ring 63 abuts against the outer wall of the cloth bag 3. The driving mechanism 9 is in transmission connection with the second lead screw 61.

[0036] The driving mechanism 9 includes a transmission component 91, a lifting electric push rod 92, a third guide rod 93, a docking block 94, and a driving motor 95. The cross-section of the docking block 94 is polygonal. A connecting sleeve 96 is provided at the output end of the driving motor 95. A docking groove 961 for sliding cooperation with the docking block 94 is provided at the top of the connecting sleeve 96. A guide seat 951 and a hanging block 952 for guiding cooperation with the third guide rod 93 are provided on the outer wall of the driving motor 95. The transmission component 91 is arranged at the bottom of the fixed bottom plate 4, and the transmission component 91 is in transmission connection with the second lead screw 61. The lifting electric push rod 92 and the third guide rod 93 are symmetrically arranged on both sides of the first lead screw 71. The output end of the lifting electric push rod 92 is fixedly connected to the hanging block 952. The connecting sleeve 96 is selectively in transmission connection with the transmission component 91. The docking block 94 is arranged at the bottom of the first lead screw 71.

[0037] The transmission component 91 includes a rotating seat 911, a first gear 912, a second gear 913, a first pulley 914, and a second pulley 915. A rotating shaft is rotatably arranged on the rotating seat 911. The first gear 912 is arranged on the connecting sleeve 96. The first pulley 914 and the second gear 913 are arranged on the rotating shaft, and the first pulley 914 is located above the second gear 913. The second gear 913 is selectively meshed with the first gear 912. The second pulley 915 is arranged on the second lead screw 61. The second pulley 915 is in belt transmission connection with the first pulley 914.

[0038] When the flow monitoring valve monitors that the air flow discharged from the corresponding air duct 52 is lower than the preset value, the lifting electric push rod 92 can drive the hanging block 952 to move downward. The hanging block 952 drives the driving motor 95 to move downward synchronously. Through the cooperation of the third guide rod 93 and the guide seat 951, the driving motor 95 can be stably lifted and lowered. The driving motor 95 drives the connecting sleeve 96 to move downward synchronously. The docking block 94 can gradually expose from the docking groove 961. The first gear 912 on the connecting sleeve 96 gradually meshes with the second gear 913. Then, the driving motor 95 drives the connecting sleeve 96 to rotate. The connecting sleeve 96 can drive the first lead screw 71 to rotate by using the cooperation of the docking groove 961 and the docking block 94. The connecting sleeve 96 also drives the second gear 913 to rotate through the first gear 912. The second gear 913 drives the rotating shaft to rotate, and the rotating shaft drives the first pulley 914 to rotate. The first pulley 914 drives the second pulley 915 to rotate through the belt. The second pulley 915 drives the second lead screw 61 to rotate. The cooperation between the second lead screw 61 and the threaded hole can drive the brush ring 63 to lift and lower. The cooperation between the second guide rod 62 and the guide hole can ensure the stable lifting and lowering of the brush ring 63. After the first lead screw 71 and the second lead screw 61 rotate synchronously, the brush ring 63 and the flapping disc body 82 also lift and lower synchronously. At this time, the convex block 836 and the transmission block 837 are staggered, that is, the convex block 836 will not contact the transmission block 837 when it lifts and lowers with the flapping disc body 82. In this way, the cloth bag 3 can be supported by all the arc-shaped abutting plates 81. The cloth bag 3 can be tightened by the arc-shaped abutting plates 81 and the brush ring 63. The brush ring 63 can remove the dust with higher viscosity on the outer wall of the cloth bag 3.

[0039] Furthermore, a protective cover body 46 is provided on the fixed bottom plate 4. The protective cover body 46 is provided with an avoidance groove for the belt to pass through. The protective cover body 46 can not only protect the relevant components but also prevent dust from entering.
