Description

Technical Field

[0001] The invention relates to the technical field of quartz sand magnetic separation equipment, in particular to a rotary magnetic separation and conveying equipment for building material quartz sand. Background Art

[0002] The presence of certain iron impurities in quartz sand greatly reduces its use value and affects the quality of the product. For example, in the production of glass, iron impurities will have a great impact on the production and quality of glass, especially on the thermodynamic properties of the glass melting process and the light transmittance of the finished glass. Therefore, in the production process of building material quartz sand, it is particularly important to improve the quality of quartz sand and reduce the content of iron. Magnetic separation equipment is commonly used to screen iron impurities in building material quartz sand.

[0003] A Chinese utility model patent with announcement number CN219985008U discloses a high-efficiency magnetic separation device for quartz sand, comprising a support frame, a box body is provided above the support frame, two motors are provided on one side of the box body, the rotating shaft of the motor passes through the box body and is fixedly connected to the active roller shaft, a driven roller shaft is provided on the side of the box body away from the active roller shaft, the active roller shaft and the driven roller shaft are connected by a transmission belt, a plurality of equidistantly arranged magnetic strips are provided in the transmission belt, a support plate is provided on the box body below the transmission belt, a storage box is provided above the support plate, two symmetrical mounting rods are provided above the storage box, two symmetrical mounting plates are fixedly mounted on the mounting rods, bristles are provided on the mounting plates, and a feed trough is provided on the side of the box body close to the motor.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the quartz sand to be magnetically separated enters the conveyor belt from the feed trough. The conveyor belt is provided with a plurality of equidistantly arranged magnetic strips, which can adsorb the magnets inside the quartz sand, thereby magnetically separating the quartz sand through the magnetic strips. When the conveyor belt with the adsorbed magnets passes through the bristles, the bristles will scrape off the magnets attached to the conveyor belt, causing the magnets to fall into the storage box for collection, thereby completing the screening of the magnets. However, when the quartz sand to be magnetically separated enters the conveyor belt from the feed trough, it is often accumulated on the conveyor belt, and the quartz sand is difficult to flatten on the conveyor belt. The magnetic strips have poor adsorption capacity for the magnets in the accumulated quartz sand, and the screened quartz sand may still contain a large amount of magnets, resulting in poor screening effect. Therefore, it is necessary to improve the design of the quartz sand magnetic separation equipment in the related technology. Summary of the invention

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0035] like Figure 1-10As shown, the embodiment of the present application discloses a rotary magnetic separation and conveying device for building material quartz sand, comprising a box body 1, a feed hopper 2 is arranged on the top of the box body 1, a feed assembly 3 for adding quartz sand to be magnetically separated into the feed hopper 2 is arranged on one side of the box body 1, a quartz sand discharge port 11 and a magnetic impurity discharge port 12 are arranged at the bottom of the box body 1, and a first conveying assembly 4 for conveying quartz sand discharged from the quartz sand discharge port 11 and a second conveying assembly for conveying magnetic impurities discharged from the magnetic impurity discharge port 12 are arranged below the box body 1 5 (the first conveying assembly 4, the second conveying assembly 5 and the feeding assembly 3 all adopt the belt transmission method commonly used in the prior art to convey the materials, and the specific designs of the corresponding mounting frames are all conventional designs, so as to meet the position requirements of the box body 1, the feeding hopper 2, the quartz sand discharge port 11 and the magnetic impurity discharge port 12 in this application, and it is necessary to ensure the stability of the box body 1 during use, such as: the bottom of the box body 1 can be fixed to the top of the mounting frame of the first conveying assembly 4, and the above parts are all conventional settings, and there is no need to elaborate on them here). A flat cylinder 6 for receiving the quartz sand falling from the feed hopper 2 is fixed at a position near the bottom of the feed hopper 2 in the box body 1, and the side of the flat cylinder 6 away from the feed hopper 2 is located directly above the quartz sand discharge port 11, and a magnetic adsorption component 7 is attached and fixed to the inner wall of the flat cylinder 6 away from the feed hopper 2, and the cross-section of the magnetic adsorption component 7 is "J"-shaped (the magnetic adsorption component 7 can select a magnetic strip with stronger magnetic force in the prior art, and a plurality of magnetic strips are fixed in sequence to form a "J"-shaped structure matching the side of the inside of the flat cylinder 6 near the quartz sand discharge port 11), one end of the magnetic adsorption component 7 extends to the top of the flat cylinder 6, and the other end of the magnetic adsorption component 7 extends to above the magnetic impurity discharge port 12, and a driving mechanism 8 for leveling the quartz sand falling onto the flat cylinder 6 and driving the quartz sand to move along the outer surface of the flat cylinder 6 is provided in the box body 1. The flat cylinder 6 is made of a material (such as plastic) with a certain hardness and good magnetic permeability (capable of allowing magnetic fields to pass through), so that the magnetic adsorption component 7 can well adsorb magnetic impurities in the quartz sand transmitted to the outer surface of the flat cylinder 6.

[0036] It should be noted here that the quartz sand to be magnetically separated enters the feed hopper 2 from the feed component 3, and then the quartz sand falls from the discharge end of the feed hopper 2 to the top of the flat cylinder 6. The driving mechanism 8 can flatten the quartz sand that falls on the flat cylinder 6 and drive the quartz sand to move along the outer surface of the flat cylinder 6. When the quartz sand moves to the position of the flat cylinder 6 close to the quartz sand discharge port 11, the magnetic impurities in the flattened quartz sand are adsorbed by the magnetic adsorption component 7, and the non-magnetic quartz sand falls from the quartz sand discharge port 11 to the first conveying component 4, and is finally transmitted to the quartz sand pile. The magnetic impurities continue to move along the outer surface of the flat cylinder 6 under the action of the driving mechanism 8. When the magnetic impurities move to the side of the magnetic adsorption component 7 away from the quartz sand discharge port 11, the magnetic adsorption effect of the magnetic adsorption component 7 disappears, and the magnetic impurities fall from the magnetic impurity discharge port 12 to the second conveying component 5, and are finally transmitted to the magnetic impurity pile. The present application changes the way of screening magnetic impurities in quartz sand and improves the screening effect.

[0037] The driving mechanism 8 includes a driving assembly 81 and a scraping assembly 82; the driving assembly 81 includes an active rod 811 rotatably mounted between the side walls on both sides of the box body 1, a driving sprocket 812 fixedly sleeved on the active rod 811, a driven rod 813 movably arranged between the side walls on both sides of the box body 1 and arranged parallel to the active rod 811, a driven sprocket 814 fixedly sleeved at a position corresponding to the driven rod 813 and the driving sprocket 812, and a driven sprocket 814 for connecting the driven sprocket 814 and the driving sprocket 812 and meshing with the driven sprocket 814 and the driving sprocket 812. The box body 1 is provided with a transmission chain 815 and a driving motor 816 fixed to the outer wall of the box body 1 and used to drive the active rod 811 to rotate; there are two driven sprockets 814, driving sprockets 812 and transmission chains 815, and they are symmetrically distributed on both sides of the flat cylinder 6; the box body 1 is provided with an adjustment component 9 for driving the driven rod 813 to move toward or away from the active rod 811 to adjust the tightness of the transmission chain 815; the leveling component 82 is installed between the two transmission chains 815 and is used to level the quartz sand that falls onto the flat cylinder 6.

[0038] The scraping assembly 82 is provided with multiple groups and is evenly arranged on the transmission chain 815. The scraping assembly 82 includes a mounting rod 821 fixed between the transmission chains 815 on both sides and parallel to the active rod 811, a hard plate body 822 hinged on the mounting rod 821, a flexible scraper 823 fixed to the side of the hard plate body 822 away from the mounting rod 821, and an elastic member 824 fixed to the hard plate body 822 so that the side of the flexible scraper 823 away from the hard plate body 822 is pressed against the outer surface of the flat cylinder 6, the side of the elastic member 824 away from the hard plate body 822 is fixed to the hinge 8221 between the hard plate body 822 and the mounting rod 821, and the length direction of the flexible scraper 823 is parallel to the length direction of the mounting rod 821.

[0039] It should be noted here that: in this embodiment, the flexible scraper 823 can be made of a flexible material with a certain strength, such as a plastic plate, and the elastic member 824 can be made of a material with a certain elasticity and a certain rigidity, such as a metal sheet, a tension spring, a torsion spring, etc. (the elastic member 824 in the figure is only a simple illustration).

[0040] After the driving motor 816 starts working and drives the active rod 811 to rotate, the active sprocket 812 on the active rod 811 drives the driven sprocket 814 and the driven rod 813 fixed to the driven sprocket 814 to rotate through the transmission chain 815. In this process, the mounting rod 821 moves synchronously with the transmission chain 815. The hard plate body 822 on the mounting rod 821 acts on the flexible scraper 823 under the action of the elastic member 824, so that the side of the flexible scraper 823 away from the hard plate body 822 is pressed against the outer surface of the flat cylinder 6, thereby flattening the quartz sand raw material that falls onto the flat cylinder 6, and in the process of the movement of the mounting rod 821, the flexible scraper 823 moves synchronously with the mounting rod 821, so that the quartz sand can move along the outer surface of the flat cylinder 6, so as to screen the magnetic impurities in the quartz sand and improve the magnetic separation quality of the quartz sand.

[0041] In order to facilitate the cleaning of a small amount of magnetic impurities and other substances attached to the bottom of the flat cylinder 6 , a plurality of parallel triangular prisms 61 are fixed to the outer bottom surface of the flat cylinder 6 , and the plurality of triangular prisms 61 are all located directly above the magnetic impurity discharge port 12 .

[0042] It should be noted here that: the arrangement of multiple triangular prisms 61 makes it possible for the flexible scraper 823 to briefly shake when it contacts the triangular prism 61 during the process of rotating with the transmission chain 815, under the action of the elastic member 824 and the hard plate body 822, thereby removing a small amount of magnetic impurities attached to the flexible scraper 823. In addition, the flexible scraper 823 strikes the bottom of the flat cylinder 6 under the action of the elastic member 824 and the hard plate body 822, and the vibration force generated by the striking removes a small amount of magnetic impurities at the bottom of the flat cylinder 6 near the triangular prism 61. Finally, the magnetic impurities fall from the magnetic impurity discharge port 12 to the second conveying component 5, and are transmitted to the magnetic impurity pile for centralized treatment.

[0043] The side walls on both sides of the box body 1 are penetrated with a slot 13 for the driven rod 813 to slide horizontally. The adjustment assembly 9 includes a guide rod 91 fixed on the outer wall of the box body 1 on the side away from the quartz sand discharge port 11, a threaded shaft 92 rotatably installed on the side wall of the box body 1 on the same side as the guide rod 91 and parallel to the guide rod 91, a hand wheel 93 fixed to the end of the threaded shaft 92 away from the box body 1, a movable plate 94 jointly arranged on the threaded shaft 92 and the guide rod 91, a connecting rod 95 fixed on the side wall of the movable plate 94 close to the box body 1, and a connecting rod 95 and a connecting rod 95 away from the movable plate 94. A lower bearing seat 96 is fixed at one end of the plate 94; the guide rod 91 passes through the movable plate 94 and slides with the movable plate 94, the threaded shaft 92 passes through the movable plate 94 and is threadedly connected to the movable plate 94, the connecting rod 95 is located outside the box body 1 and is parallel to the guide rod 91, the connecting rods 95 are arranged in pairs, the lower bearing seat 96 and the ends of the two paired connecting rods 95 are fixed, the connecting rods 95 are provided with two pairs and distributed on both sides of the box body 1, the lower bearing seats 96 are provided with two and distributed on both sides of the box body 1, and the two ends of the driven rod 813 are rotatably connected with the lower bearing seats 96 on both sides of the box body 1 respectively.

[0044] It should be noted here that: the staff can rotate the threaded shaft 92 by turning the hand wheel 93. Since the threaded shaft 92 is threadedly connected to the movable plate 94, the guide rod 91 and the movable plate 94 slide together, so that the movable plate 94 moves toward or away from the side of the box body 1. The movable plate 94 drives the lower bearing seat 96 to move through the connecting rod 95. Since the driven rod 813 slides with the slot 13 on the box body 1, the driven rod 813 between the lower bearing seats 96 on both sides of the box body 1 moves along the slot 13 toward or away from the active rod 811. Therefore, the active sprocket 8 12 and the driven sprocket 814 can be adjusted, and the tightness of the transmission chain 815 connecting the active sprocket 812 and the driven sprocket 814 can be adjusted, so that the staff can adjust the tightness of the transmission chain 815 to the extent that the side of the flexible scraper 823 away from the hard plate body 822 can be pressed against the outer surface of the flat cylinder 6, so as to ensure that during the subsequent rotation of the transmission chain 815, the flexible scraper 823 can scrape the quartz sand on the outer surface of the flat cylinder 6 flat and make the quartz sand move along the outer surface of the flat cylinder 6, which is beneficial for the magnetic adsorption component 7 to screen the magnetic impurities entrained in the quartz sand.

[0045] A square frame 14 located between the flat cylinder 6 and the inner wall of the box 1 is fixed to the inner wall of the box 1. The square frame 14 is provided with two and symmetrically arranged on both sides of the flat cylinder 6. Each square frame 14 is provided with an auxiliary component 15 for assisting in adjusting the tightness of the transmission chain 815 on one side of the flat cylinder 6. The auxiliary components 15 on each square frame 14 are provided with two groups and are mirror-set about the middle of the square frame 14. Each group of auxiliary components 15 includes a vertical rod 151 that is arranged through the square frame 14 and slidably cooperates with the square frame 14, a guide groove 152 that is fixed to one end of the vertical rod 151 away from the middle of the square frame 14 and parallel to the guide rod 91, and a guide groove 152 that is fixed to the inner top of the square frame 14.

[0048] The feed hopper 2 is provided with a cylindrical material control portion 21 near its discharge end, and the box body 1 is provided with a material control component 17 for controlling the discharge amount of the feed hopper 2.

[0049] It should be noted here that: after the material control motor 175 starts working, it drives the lower active wheel 176 to rotate, and the lower driven wheel 174 drives the mounting cylinder 173 to rotate under the action of the lower closed transmission belt 177. Since the mounting cylinder 173 is key-connected with the driving rod 178, the driving rod 178 and the multiple material control plates 179 on the driving rod 178 are all rotated. Since the material control plate 179 extends from the side away from the driving rod 178 to a position close to the inner surface of the cylindrical material control part 21, it is convenient for the staff to control the amount of material output from the cylindrical material control part 21 to the discharge end of the feed hopper 2 according to the progress of the magnetic separation of quartz sand.

[0050] The driving rod 178 is fixedly sleeved with a spline 1781 located on the outside of the feed hopper 2, and the mounting tube 173 is provided with a keyway 1731 that engages with the spline 1781. A vertical plate 18 is fixed to the side wall of the box body 1 on the same side as the lower horizontal plate 171, and a movable groove 19 for the feed hopper 2 to move is provided on the top of the box body 1. An L-shaped plate body 10 is fixed to the top of the box body 1 near the movable groove 19. A rectangular plate body 22 is fixedly sleeved on the outer wall of the feed hopper 2. The upper surface of the rectangular plate body 22 fits with the bottom surface of the horizontal part of the L-shaped plate body 10. The L-shaped plate body 10 is provided with two and is symmetrically arranged about the feed hopper 2. The side walls on both sides of the rectangular plate body 22 are close to the vertical parts of the two L-shaped plate bodies 10. One side of the box 1 is fitted, the bottom surface of the rectangular plate 22 is flush with the top of the box 1, and an "I"-shaped slide rail 23 parallel to the L-shaped plate 10 is fixed on the inner wall of the box 1. The "I"-shaped slide rail 23 is provided with two and symmetrically distributed on both sides of the feed hopper 2, and rollers 24 that cooperate with the "I"-shaped slide rail 23 are rotatably installed on both sides of the feed hopper 2; a shaking component 25 for driving the feed hopper 2 to reciprocate along the length direction of the "I"-shaped slide rail 23 is provided on the box 1, and the shaking component 25 includes an upper horizontal plate fixed on the side wall of the box 1 251, an upper bearing seat 252 fixed to the top of the upper horizontal plate 251, a driven shaft 253 penetrating the upper bearing seat 252 and rotatably connected to the upper bearing seat 252, an upper driven wheel 254 fixed to one end of the driven shaft 253, a circular plate body 255 fixed to the other end of the driven shaft 253, a first connecting rod 256 rotatably connected to a side of the circular plate body 255 away from the upper bearing seat 252, a second connecting rod 257 rotatably connected to an end of the first connecting rod 256 away from the circular plate body 255, a rotatably mounted An upper driving wheel 258 on the vertical plate 18, a shaking motor 259 fixed on the vertical plate 18 and used to drive the upper driving wheel 258 to rotate, and an upper closed transmission belt 250 for connecting the upper driving wheel 258 and the upper driven wheel 254; the second connecting rod 257 is horizontally arranged, the second connecting rod 257 passes through the side wall of the box body 1 and slides with the box body 1, the end of the second connecting rod 257 away from the first connecting rod 256 is fixed to the outer wall of the feed hopper 2, and the position of the upper driven wheel 254 corresponds to the position of the upper driving wheel 258.

[0051] It should be noted here that: when the shaking motor 259 is working, the shaking motor 259 drives the upper driving wheel 258 to rotate, and the upper driving wheel 258 drives the upper driven wheel 254, the driven shaft 253 fixed to the upper driven wheel 254, and the circular plate body 255 fixed to one end of the driven shaft 253 to rotate under the action of the upper closed transmission belt 250. The circular plate body 255 pushes and pulls the feed hopper 2 through the first connecting rod 256 and the second connecting rod 257, so that the feed hopper 2 reciprocates in the movable groove 19. At the same time, the roller 24 on the feed hopper 2 reciprocates along the "I"-shaped slide rail 23. Since the driving rod 178 penetrates the side wall of the feed hopper 2 and is connected to the movable groove 19, the roller 24 on the feed hopper 2 reciprocates along the "I"-shaped slide rail 23. The feed hopper 2 cooperates, and the spline 1781 on the driving rod 178 cooperates with the key slot 1731 in the mounting tube 173. Therefore, the driving rod 178, the material control plate 179 and the spline 1781 all swing synchronously with the feed hopper 2. The spline 1781 slides back and forth along the key slot 1731 during the above process and can rotate synchronously with the mounting tube 173, thereby ensuring the normal operation of the material control assembly 17. After the feed hopper 2 swings, it is beneficial for the quartz sand discharged from the cylindrical material control part 21 to be smoothly discharged from the lower end of the feed hopper 2, which fully reduces the probability of quartz sand accumulating at the lower end of the feed hopper 2 and affecting the quartz sand magnetic separation process, thereby helping to improve the screening efficiency of quartz sand.

[0052] In this embodiment, in order to facilitate the staff to install the driving mechanism 8 and other parts (such as the vertical rod 151, the square frame 14, the guide groove 152, the hexagonal prism 153, the threaded rod 154, etc.) in the box body 1, the side panels on both sides of the box body 1 can be detachably connected to the other frame panels constituting the box body 1 by bolts. After all the components in the box body 1 are assembled and adjusted, the side panels on both sides of the box body 1 are fixed.

[0053] The use principle of a rotary magnetic separation and conveying equipment for building material quartz sand in the present embodiment is as follows: the quartz sand raw material entering from the feed hopper 2 falls onto the flat cylinder 6, and the driving mechanism 8 drives the quartz sand to move along the outer surface of the flat cylinder 6 while leveling the quartz sand. When the quartz sand moves to the position of the flat cylinder 6 close to the quartz sand discharge port 11, the magnetic adsorption component 7 adsorbs the magnetic impurities mixed in the quartz sand, and the quartz sand that does not have magnetism falls from the quartz sand discharge port 11 to the first conveying component 4 for transmission, which changes the situation in traditional technology where it is difficult to level the fallen quartz sand, and improves the efficiency of removing magnetic impurities in the quartz sand.

[0054] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
