Description

Technical Field

[0001] This application belongs to the technical field of ore processing equipment, and particularly relates to an aggregate type iron removal device. Background Art

[0002] Currently, most non-magnetic ore types have relatively fine dissemination sizes, and ultimately need to go through grinding and separation to obtain high-quality concentrate products. The maximum particle size of the ore mined in the stope is generally 600 - 1200 mm, while the feed particle size for grinding is generally below 12 mm. This requires us to set up a crushing operation before grinding. Generally, the mined ore needs to undergo continuous three to four stages of crushing before entering the grinding to make its particle size meet the requirements of grinding. Since the fine crushing cone crusher and the ultra-fine high-pressure roller mill are very likely to cause ore jamming due to the mixing of ironware during the medium crushing operation, resulting in crusher overload and damage to the crushing chamber.

[0003] In the prior art, iron removal equipment is usually used to remove iron from the products of the medium crushing operation. Since the medium crushing operation generally uses a cone crusher with a relatively large crushing chamber, its discharge is in a circular circumferential pattern. This discharge method cannot directly feed the traditional iron removal equipment. The ore crushing and iron removal operations are usually carried out separately. Generally, an independent disk iron remover or belt iron remover is suspended above the feed belt of the fine crushing and ultra-fine crushers. After the ore is crushed, it still needs to be transported to the disk iron remover or belt iron remover for iron removal. This method of using independent iron removal equipment has large equipment specifications, occupies a large space, and has relatively high equipment purchase and workshop investment costs. Summary of the Invention

[0004] Therefore, the technical problem to be solved by this application is to provide an aggregate type iron removal device that can integrate the crushing operation and the iron removal operation to reduce equipment costs and workshop investment costs.

[0023] By arranging the iron removal part to adsorb iron foreign matters in the material, it is possible to avoid ore jamming caused by iron foreign matters mixed in the fine crusher and the ultra-fine high-pressure roller mill operations. At the same time, by arranging the iron removal part to be communicated with the crushing part 1, the crushing part 1 can directly feed the iron removal part, realizing the integration of the crushing operation and the iron removal operation, eliminating the need to set up an independent iron removal device, reducing the equipment purchase and workshop investment costs.

At the same time, by setting the thickness of the flexible pad 6 to 25 mm, it can ensure that the iron removal unit 4 has a strong adsorption force, so that the iron foreign matters in the material can be completely removed.

[0031] The conical crusher-integrator further includes an aggregate hopper 5. The crushing part 1 is connected to the iron removal feeding box 3 through the aggregate hopper 5, and the aggregate hopper 5 is coaxially arranged with the crushing part 1.

[0032] Among them, the aggregate hopper 5 can be arranged on the axial side of the crushing part 1. The crushing part 1 is connected to the iron removal part through the aggregate hopper 5. One end of the aggregate hopper 5 close to the crushing part 1 is circular, so that the aggregate hopper 5 can match the material outlet of the crushing part 1, and the crushing part 1 can directly feed the material to the aggregate hopper 5; one end of the aggregate hopper 5 close to the iron removal part is rectangular, so that the aggregate hopper 5 can match the feed inlet of the iron removal part, and the aggregate hopper 5 can directly feed the material to the iron removal part.

[0033] Specifically, in the embodiment of the present application, the aggregate hopper 5 is coaxially arranged with the crushing part 1. By providing the aggregate hopper 5, the crushing part 1 and the iron removal part are integrated into one device, avoiding the setting of an independent disk or belt type iron remover, and realizing the integration of the crushing operation and the iron removal operation, so as to reduce the equipment cost and the workshop investment cost. At the same time, the aggregate hopper 5 is coaxially arranged with the crushing part 1, which can reduce the equipment volume and the occupied space, and does not require multiple staff to watch the equipment, so as to reduce the operation cost and the maintenance cost of the equipment.

[0034] The aggregate hopper 5 includes a first section 51 and a second section 52. One end of the first section 51 close to the crushing part 1 is circular, and the end far from the crushing part 1 is rectangular.

The busbar inclination angle of the first section 51 is A, and 50°≤A≤60°. The second section 52 is arranged on the side of the first section 51 far from the crushing part 1, and the second section 52 is rectangular.

[0035] Among them, the first section 51 is generally circular ring-shaped. One end of the first section 51 far from the iron removal part is connected to the crushing part 1, and one end of the first section 51 far from the crushing part 1 is connected to the second section 52. The second section 52 is connected to the iron removal part.

[0036] Specifically, one end of the first section 51 away from the second section 52 can be circular, and one end of the first section 51 close to the second section 52 can be rectangular. At the same time, the cross-sectional area of the first section 51 perpendicular to the central axis of the first section 51 at the end close to the crushing part 1 is larger than the cross-sectional area of the first section 51 perpendicular to the central axis of the first section 51 at the end close to the iron removal part, which can realize the centralized cloth of the crushed material from the annular circumferential cloth to the long strip vertically downward, and can avoid the excessive distance between the material boundary and the iron removal unit 4, improving the iron removal effect.

[0037] Among them, the busbar inclination angle of the first section 51 is A, 50°≤A≤60°. In the embodiment of the present application, the busbar inclination angle A of the first section 51 is preferably 55°.

[0038] Among them, the second section 52 is generally rectangular, and the cross-sectional area of the second section 52 perpendicular to the central axis of the second section 52 at the end close to the first section 51 is equal to the cross-sectional area of the second section 52 perpendicular to the central axis of the second section 52 at the end away from the second section 52.

[0039] Specifically, any cross-sectional area of the second section 52 perpendicular to the central axis of the second section 52 is less than or equal to any cross-sectional area of the first section 51 perpendicular to the central axis of the first section 51, so as to reduce the sorting width of the material and avoid the excessive distance between the material boundary and the iron removal unit 4, optimizing the sorting environment of the iron removal unit 4 and improving the iron removal effect.

[0040] The first section 51 is arranged on the outer peripheral side of the crushing part 1, and the distance between the first section 51 and the outer peripheral wall of the crushing part 1 is B, 50mm≤B≤100mm. The first section 51 is connected to the second section 52. The length of the second section 52 is C, 1000mm≤C≤2000mm, and the width of the second section 52 is D, 200mm≤D≤400mm.

[0041] Among them, the aggregate type iron removal device further includes a frame 2. The frame 2 includes a first platform and a second platform. The crushing part 1 is arranged on the upper part of the first platform and connected to the first platform. The aggregate hopper 5 is arranged under the first platform and connected to the first platform. The connection methods are all bolt connection or welding, etc., and the present application does not make further limitations.

[0042] Among them, one end of the aggregate hopper 5 away from the iron removal part is arranged on the outer peripheral side of the end of the crushing part 1 close to the iron removal part. The distance between the aggregate hopper 5 and the outer peripheral wall of the crushing part 1 is B, 50mm≤B≤100mm. In the embodiment of the present application, the distance between the aggregate hopper 5 and the outer peripheral wall of the crushing part 1 is preferably 75mm, so that the material can completely enter the aggregate hopper 5 after being discharged from the crushing part 1, and the material can be prevented from spilling.

[0043] Among them, the length of the second section 52 is C, where 1000 mm ≤ C ≤ 2000 mm. In the embodiment of the present application, the length of the second section 52 is preferably 1500 mm.

[0044] Among them, the width of the second section 52 is D, where 200 mm ≤ D ≤ 400 mm. In the embodiment of the present application, the width of the second section 52 is preferably 300 mm.

[0045] Specifically, in the present application, by providing a stable flow channel for the material through the aggregate hopper 5, the material generated by the crushing part 1 can directly enter the iron removal part through the aggregate hopper 5. By adsorbing the iron foreign matter in the material through the iron removal part, it is possible to avoid ore jamming caused by the mixed iron foreign matter during the operation of the fine crusher and the ultra-fine high-pressure roller mill, thereby realizing the integration of the crushing operation and the iron removal operation equipment, reducing the equipment purchase and workshop investment costs. At the same time, by setting the aggregate hopper 5, the crushed material can be changed from the annular circumferential cloth to the beam-shaped cloth vertically downward from the long strip-shaped outlet, thereby reducing the sorting width of the material to 300 mm, avoiding the situation where the magnetic field strength decreases too much when the boundary material is too far from the iron removal unit 4 due to the too wide sorting width of the material, resulting in some iron impurities not being adsorbed, optimizing the sorting environment of the iron removal plate, and improving the iron removal effect.

[0046] Through holes 31 are provided in the circumferential direction of the iron removal feed box 3. There are two through holes 31, and the two through holes 31 are symmetrically arranged along the plane where the central axis of the iron removal feed box 3 is located. The iron removal unit 4 penetrates through the iron removal feed box 3 through the two through holes 31.

[0047] Among them, multiple through holes 31 can be provided, and multiple iron removal units 4 can be provided. One iron removal unit 4 corresponds to two through holes 31, and the iron removal unit 4 penetrates through the two through holes 31 at the same time. In the embodiment of the present application, one iron removal unit 4 is provided and two through holes 31 are provided.

[0048] Among them, the two through holes 31 are symmetrically arranged along the plane where the central axis of the iron removal feed box 3 is located. The iron removal unit 4 is inserted into the iron removal feed box 3 through the two through holes 31. The iron removal unit 4 is movably connected to the two through holes 31, and the iron removal unit 4 can move in the iron removal feed box 3 along the extension direction of the iron removal unit 4.

[0049] Specifically, the iron removal unit 4 can be rectangular. The cross-sectional dimension of the iron removal unit 4 in the vertical direction is smaller than the cross-sectional dimension of the through hole 31 in the vertical direction. In the embodiment of the present application, traction holes 9 are provided at both ends of the iron removal unit 4. The diameter of the traction hole 9 is preferably 15 mm. The traction hole 9 is connected to a traction rope. The traction hole 9 is used to drive the iron removal unit 4 to be inserted and pulled out in the iron removal feed box 3 through the traction rope, improving the installation and maintenance efficiency of the iron removal unit 4.

[0050] The distance between the two through holes 31 and the outer peripheral wall of the second section 52 of the aggregate hopper 5 is E, where 200 mm ≤ E ≤ 300 mm, and the distance between the two through holes 31 and the outer wall of the end of the aggregate hopper 5 away from the crushing section 1 is F, where 300 mm ≤ F ≤ 500 mm.

[0051] Among them, the distance between the through hole 31 and the outer peripheral wall of the second section 52 is E, where 200 mm ≤ E ≤ 300 mm. In the embodiment of the present application, the distance between the through hole 31 and the outer peripheral wall of the second section 52 is preferably 250 mm.

[0052] Among them, the distance between the through hole 31 and the outer wall of the end of the aggregate hopper 5 away from the crushing section 1 is F, where 300 mm ≤ F ≤ 500 mm. In the embodiment of the present application, the distance between the through hole 31 and the outer wall of the end of the aggregate hopper 5 away from the crushing section 1 is preferably 400 mm.

[0053] Specifically, by setting the distance between the through hole 31 and the outer peripheral wall of the second section 52 to be 250 mm and the distance between the through hole 31 and the outer wall of the end of the aggregate hopper 5 away from the crushing section 1 to be 400 mm, the installation position of the iron removal unit 4 is accurate, and the iron removal unit 4 can be installed on one side of the material flow of the iron removal feeding box 3 to adsorb iron foreign matters in the material, improving the iron removal effect.

[0054] The length of the iron removal unit 4 is G, where 1300 mm ≤ G ≤ 2500 mm, the width of the iron removal unit 4 is H, where 80 mm ≤ H ≤ 100 mm, the height of the iron removal unit 4 is I, where 300 mm ≤ I ≤ 500 mm, the height of the two through holes 31 is J, where 1.2I ≤ J ≤ 1.3I, and the width of the two through holes 31 is K, where 1.1H ≤ K ≤ 1.2H.

[0059] Among them, the width of the through hole 31 is K, where 1.1H ≤ K ≤ 1.2H. In the embodiment of the present application, the width of the through hole 31 is preferably 104 mm.

[0060] Specifically, the length of the iron removal unit 4 is greater than that of the iron removal feed box 3, the height of the iron removal unit 4 is less than that of the through hole 31, and the width of the iron removal unit 4 is less than that of the through hole 31, so that the iron removal unit 4 can be inserted into and pulled out of the iron removal feed box 3 through the two through holes 31, improving the installation and maintenance efficiency of the iron removal unit 4.

[0061] The iron removal part further includes a flexible pad 6, the flexible pad 6 is arranged on the outer peripheral side of the iron removal unit 4, the thickness of the flexible pad 6 is L, 20mm ≤ L ≤ 30mm, and the magnetic field intensity of the iron removal unit 4 is M, 100mT ≤ M ≤ 200mT.

[0062] Among them, the flexible pad 6 can be made of materials such as rubber. The flexible pad 6 is arranged on the outer peripheral side of the iron removal unit 4 and is fixedly connected to the iron removal unit 4. The connection method can be riveting or bolt connection, etc., and no further limitation is made here.

[0063] Among them, the thickness of the flexible pad 6 is L, 20mm ≤ L ≤ 30mm. In the embodiment of the present application, the thickness of the flexible pad 6 is preferably 25mm.

[0064] Among them, the magnetic field intensity of the iron removal unit 4 is M, 100mT ≤ M ≤ 200mT. In the embodiment of the present application, the magnetic field intensity of the iron removal unit 4 is preferably 150mT.

[0065] Specifically, by setting the flexible pad 6, it can be avoided that the iron removal unit 4 is worn by the impact of the material flow, so that the service life of the iron removal unit 4 is increased. At the same time, by setting the magnetic field intensity of the iron removal unit 4 to 150mT, a stable adsorption force can be provided for the iron foreign matters in the material, making the material impurity removal more thorough and improving the iron removal efficiency.

[0066] The iron removal part further includes a collection device 7 and a control box. The collection device 7 is arranged on the axial side of the iron removal unit 4. The control box is electrically connected to the collection device 7 and is also electrically connected to the iron removal unit 4. The collection device 7 is used to obtain the pressure information of the iron removal unit 4 and send the pressure information to the control box. The control box is used to control the start and stop of the iron removal unit 4 according to the pressure information.

[0067] Among them, the iron removal unit 4 is arranged on the iron removal plate base. Two iron removal plate bases can be set, and the two iron removal plate bases are symmetrically arranged. The iron removal plate bases are arranged on the support beam of the iron removal feed box 3. End sleeves of the iron removal plate are sleeved on both ends of the iron removal unit 4, and the end sleeves of the iron removal plate are connected to the iron removal plate base.

[0068] Among them, two collection devices 7 can be set. The collection device 7 can be other pressure detection devices such as a pressure gauge, and no further limitation is made in the present application. The collection device 7 is used to detect the pressure value of the iron removal unit 4 in real time and send the pressure information to the control box.

[0069] Specifically, the collection device 7 is connected to the iron removal plate base and the support beam. The connection method can be bolt perforation connection without tightening screws. By setting the connection method between the collection device 7 and the iron removal unit 4 without tightening the bolts, the collection device 7 and the iron removal unit 4 can be limited in the radial direction of the bolts, so that the information obtained by the collection device 7 is more accurate. At the same time, the upper edge of the collection device 7 is higher than the lower edge of the through hole 31, so that while the iron removal unit 4 is smoothly inserted and pulled out, the non-contact between the iron removal plate and the iron removal plate through hole is ensured, and the accuracy of the pressure measurement of the collection device 7 is improved.

[0070] Among them, the collection device 7 is electrically connected to the control box, and at the same time, the control box is also electrically connected to the iron removal unit 4. The control box can control the on and off of the iron removal unit 4 according to the pressure information detected by the collection device 7 for the iron removal unit 4.

[0071] Specifically, the collection device 7 sends the pressure information of the iron removal unit 4 to the control box. When the pressure information exceeds the pressure threshold, the control box outputs a power-off signal to the iron removal unit 4, so that the iron foreign matter adsorbed on the surface of the iron removal unit 4 slides off. At the same time, after a set time, the control box controls the iron removal unit 4 to be powered on to continue iron removal.

[0072] Among them, the set time can be 10 - 20s. In the embodiment of the present application, the set time is 15s. After the iron removal unit 4 is powered off for 15s, the control box automatically interlocks the iron removal unit 4 to be powered on to continue iron removal.

[0073] Specifically, in the embodiment of the present application, by setting the control box to interlock the high-level alarm of the collection device 7 and the power-off signal of the iron removal unit 4, it can be realized that when the pressure value of the iron removal unit 4 exceeds the pressure threshold, the power is automatically cut off, so that the iron foreign matter attached to the surface of the iron removal unit 4 falls off. At the same time, the control box controls the iron removal unit 4 to be automatically powered on after a delay of 15s, so that the iron removal unit 4 continues to adsorb the iron foreign matter in the material, realizing iron removal automation without manual operation and improving the iron removal effect.

[0074] The crushing and integrating machine further includes a discharge box 8. The discharge box 8 is communicated with the iron removal part. The discharge box 8 is arranged on the side of the iron removal part away from the crushing part 1. A partition plate 81 is provided in the discharge box 8. The partition plate 81 is arranged close to the iron removal unit 4 in the radial direction of the discharge box 8.

[0077] Specifically, the discharge box 8 further includes a partition plate 81. The partition plate 81 can be rectangular. The partition plate 81 is arranged at one end of the discharge box 8 away from the iron removal part. By setting the partition plate 81, the discharge box 8 is divided into an ore discharge chute 82 and an iron impurity discharge chute 83, so that the sorted materials can be discharged from the ore discharge chute 82, and the iron foreign matters in the materials can be discharged from the iron impurity discharge chute 83. By setting the partition plate 81, it can be avoided that the sorted materials are remixed with the iron impurity foreign matters, and the iron foreign matters can be discharged in time, improving the iron removal effect.

[0078] In the embodiment of the present invention, a kind of aggregate type iron removal device is provided. By setting an iron removal part to adsorb the iron foreign matters in the materials, it can avoid ore jamming caused by the mixed iron foreign matters in the fine crusher and the ultra-fine high-pressure roller mill operations. At the same time, by setting the iron removal part to communicate with the crushing part 1, the crushing part 1 can directly feed the iron removal part, realizing the integration of the crushing operation and the iron removal operation, without the need to set up an independent iron removal device, reducing the equipment purchase and workshop investment costs. At the same time, the aggregate type iron removal device has a simple structure and a small volume, and does not require multiple staff to guard the equipment, reducing the operation cost and maintenance cost of the equipment.
