Description

Technical Field

[0001] The embodiments of this utility model relate to the field of drying equipment technology, specifically to a drying equipment for sticky, wet, powdery mineral powder. Background Technology

[0002] Iron ore is commonly ore-milled using ball mills, resulting in iron ore powder with a moisture content of approximately 11%, which is unsuitable for direct fluidized bed calcination and magnetization roasting. When the iron ore powder is dried using drying equipment, clumping occurs due to the viscosity of the wet powder. To obtain iron ore powder with the required moisture content and particle size, it is necessary to dry and disperse the sticky, wet powder.

[0003] In the existing technology, when drying sticky and wet powdered mineral powder, it is difficult to solve the problem of breaking down and separating the sticky and wet powdered mineral powder, which leads to the agglomeration of mineral powder and poor drying effect. Therefore, we propose a drying equipment for sticky and wet powdered mineral powder. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this utility model provide a drying device for sticky and wet powdery mineral powder, which solves the problem of the inability to separate and dry mineral powder in related technologies.

[0005] According to one aspect, at least one embodiment of the present invention provides a drying device for viscous and wet powdery mineral powder, including a base plate, a support column fixedly connected to the top of the base plate, a drying barrel fixedly connected to the top of the support column, and a rotary drying mechanism provided inside the drying barrel.

[0006] The rotary drying mechanism includes a motor, the bottom of which is fixedly connected to the top of the base plate. A rotating shaft is fixedly connected to the output end of the motor. The circumferential surface of the rotating shaft penetrates and is rotatably connected to the bottom of the drying barrel. A shell is fixedly connected inside the drying barrel. A separating rod is fixedly connected to the circumferential surface of the rotating shaft. A branch rod is fixedly connected to the side of the separating rod. A hopper is fixedly connected to the top of the drying barrel. A conveying pipe is fixedly connected through the bottom of the hopper. The bottom of the conveying pipe is fixedly connected through the top of the drying barrel.

[0007] For example, in a drying device for sticky and wet powdery mineral powder provided in at least one embodiment of the present invention, a trough is provided on the inner top of the drying barrel, a baffle is slidably connected inside the trough, and a force-bearing rod is fixedly connected to the bottom of the baffle. The purpose is to ensure that the baffle blocks the flow when the conveying pipe is not in use.

[0008] A connecting rod is fixedly connected to the circumferential surface of the rotating shaft, and a scraper is fixedly connected to the end of the connecting rod away from the circumferential surface of the rotating shaft. The purpose of the scraper is to scrape off the mineral powder adhering to the inside of the housing.

[0009] A return spring is fixedly connected inside the slide groove. The end of the return spring away from the inside of the slide groove is fixedly connected to the side of the baffle. The purpose of this is to ensure that the baffle can automatically reset and reduce manual intervention.

[0010] The number of separating rods and branch rods is set to several, and they are arranged in a circular array along the circumference of the rotating axis. One end of the force-bearing rod is located on the displacement trajectory of the separating rod. The purpose is to ensure that the rotation of the separating rod can push the force-bearing rod.

[0011] According to another aspect, at least one embodiment of the present invention also provides a drying device for viscous and wet powdery mineral powder, including a heating mechanism. The heating mechanism includes a first pulley, which is fixedly connected to the circumferential surface of a rotating shaft. A belt is provided on the circumferential surface of the first pulley. A support shaft is rotatably connected inside the drying drum. A second pulley is fixedly connected to the circumferential surface of the support shaft. A mounting plate is fixedly connected to the circumferential surface of the support shaft. A conveying fan is fixedly connected to the circumferential surface of the mounting plate. The purpose is to improve the drying effect and reduce working time.

[0012] For example, in at least one embodiment of the present invention, a drying device for viscous and wet powdery mineral powder is provided, which further includes: a heater is provided inside the drying barrel, and a conveying port is provided on the circumferential surface of the shell. The number of the conveying ports is set to several and evenly distributed on the circumferential surface of the shell. The purpose is to keep the temperature inside the drying barrel constant so that the hot air can contact and dry the mineral powder.

[0013] A discharge pipe is fixedly inserted through the circumference of the drying barrel, and a valve is provided on the circumference of the discharge pipe. A collection box is fixedly connected to the side of the bottom plate. The purpose of this is to collect the processed material by discharging it into the drying barrel through the conveying port.

[0014] The circumferential surfaces of both pulley one and pulley two mesh with the interior of the belt. Pulley one is connected to pulley two via the belt for transmission, the purpose of which is to ensure that the rotation of pulley one can drive pulley two to rotate via the belt.

[0015] The number of the support shaft, pulley two, and mounting plate is set to two, and they are symmetrical to each other along the vertical central axis of the rotating shaft. The top of the collection box is located directly below the discharge pipe, which is to ensure that the dried mineral powder can accurately enter the collection box.

[0016] The beneficial effects of the embodiments of this utility model are as follows:

[0017] 1. In this utility model, through the cooperation of components such as the motor, separating rod, and scraper of the rotary drying mechanism, after the operator adds mineral powder through the hopper, the motor is started, driving the rotating shaft and separating rod to rotate. The separating rod pushes the force rod, moves the baffle, and opens the conveying pipe, allowing the mineral powder to enter the drying barrel. The separating rod impacts the mineral powder and performs fine separation through the branch rod, preventing agglomeration and ensuring uniform drying. The rotating shaft also drives the scraper to remove the mineral powder. When the separating rod leaves the force rod, the baffle automatically resets through the return spring, preventing excessive mineral powder from affecting the drying effect. This design achieves the effect of separating and drying mineral powder, improving drying efficiency and material uniformity.

[0018] 2. In this utility model, through the coordinated operation of components such as the conveying fan, heater, and collection box of the heating mechanism, the motor starts simultaneously with the heater. The rotating shaft drives pulley one to rotate, which in turn drives pulley two via a belt, thereby driving the support shaft to rotate. This drives the conveying fan to generate air pressure, blowing hot air from the heater into the housing to dry the mineral powder. The dried mineral powder then enters the collection box through a valve and discharge pipe. This design achieves the effect of heating and drying the mineral powder, improving the drying efficiency and reducing processing time. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0027] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product.

[0030] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-5 As shown, it illustrates a drying device for sticky and wet powdery mineral powder in one embodiment of the present invention, including a base plate 1, a support column 2 fixedly connected to the top of the base plate 1, a drying barrel 3 fixedly connected to the top of the support column 2, and a rotary drying mechanism 4 provided inside the drying barrel 3.

[0033] The rotary drying mechanism 4 includes a motor 41, the bottom of which is fixedly connected to the top of the base plate 1. The output end of the motor 41 is fixedly connected to a rotating shaft 42. The circumferential surface of the rotating shaft 42 passes through and is rotatably connected to the bottom of the drying barrel 3. The inside of the drying barrel 3 is fixedly connected to a shell 43. The circumferential surface of the rotating shaft 42 is fixedly connected to a separating rod 44. The side of the separating rod 44 is fixedly connected to a branch rod 45. The top of the drying barrel 3 is fixedly connected to a hopper 46. The bottom of the hopper 46 is fixedly connected to a conveying pipe 47, and the bottom of the conveying pipe 47 is fixedly connected to the top of the drying barrel 3.

[0034] In some examples, the dryer 3 is provided with a groove 48 at the top inside, a baffle 49 is slidably connected inside the groove 48, and a force-bearing rod 410 is fixedly connected to the bottom of the baffle 49. The purpose of this is to ensure that the baffle 49 blocks the flow when the conveying pipe 47 is not in use.

[0035] A connecting rod 411 is fixedly connected to the circumferential surface of the rotating shaft 42. A scraper 412 is fixedly connected to one end of the connecting rod 411 away from the circumferential surface of the rotating shaft 42. The purpose of the scraper 412 is to scrape off the mineral powder adhering to the inside of the housing 43.

[0036] A return spring 413 is fixedly connected inside the slide 48. One end of the return spring 413 away from the inside of the slide 48 is fixedly connected to the side of the baffle 49. The purpose is to ensure that the baffle 49 can automatically reset and reduce manual intervention.

[0037] The number of separating rods 44 and branch rods 45 is set to several, and they are arranged in a circular array along the circumference of the rotating shaft 42. One end of the force rod 410 is located on the displacement trajectory of the separating rod 44. The purpose is to ensure that the rotation of the separating rod 44 can push the force rod 410.

[0038] For example, such as Figures 1-5 As shown, when it is necessary to dry the sticky and wet powdery mineral powder, the operator adds it through the hopper 46. At this time, the operator starts the motor 41, and the output end of the motor 41 rotates. The rotation of the output end of the motor 41 drives the rotating shaft 42 to rotate. The rotation of the rotating shaft 42 drives the separating rod 44 to rotate. During the rotation of the separating rod 44, it pushes the force rod 410. The force rod 410 drives the baffle 49 to move inside the slide chute 48, thereby opening the conveying pipe 47, allowing the mineral powder inside the hopper 46 to enter the shell 43 inside the drying barrel 3. At this time, the rotating separating rod 44 impacts and separates the sticky and wet powdery mineral powder. At the same time, the rotation of the separating rod 44 drives the branch rod 45 to perform more precise separation, preventing agglomeration and ensuring uniform drying of the material. Meanwhile, the rotation of the rotating shaft 42 drives the scraper 412 to rotate through the connecting rod 411. The scraper 412 scrapes the mineral powder inside the shell 43. When the separating rod 44... When the baffle 49 leaves one end of the force-bearing rod 410, it automatically resets via the return spring 413 to prevent excessive addition of mineral powder from causing poor drying effect.

[0039] like Figures 1-5 As shown, this invention illustrates a drying device for sticky, wet mineral powder in another embodiment of the present invention. It is largely the same as the technical solution described above, so only the differences are emphasized. The device includes a heating mechanism 5, which comprises a pulley 51 fixedly extending through the circumferential surface of a rotating shaft 42. A belt 52 is provided on the circumferential surface of the pulley 51. A support shaft 53 is rotatably connected inside the drying drum 3. A pulley 54 is fixedly connected to the circumferential surface of the support shaft 53. A mounting plate 55 is fixedly connected to the circumferential surface of the support shaft 53. A conveying fan 56 is fixedly connected to the circumferential surface of the mounting plate 55. The purpose of this device is to improve the drying effect and reduce working time.

[0040] In some examples, the drying barrel 3 is equipped with a heater 57 inside, and the circumferential surface of the shell 43 is provided with a conveying port 58. The number of conveying ports 58 is set to several and they are evenly distributed on the circumferential surface of the shell 43. The purpose is to keep the internal temperature of the drying barrel 3 constant so that the hot air can contact the mineral powder for drying.

[0041] A discharge pipe 59 is fixedly inserted through the circumference of the drying barrel 3. A valve 510 is provided on the circumference of the discharge pipe 59. A collection box 511 is fixedly connected to the side of the bottom plate 1. The purpose of this is to collect the processed material by discharging it through the conveying port 58 into the drying barrel 3.

[0042] The circumferential surfaces of both pulley 51 and pulley 54 mesh with the interior of belt 52. Pulley 51 is connected to pulley 54 via belt 52, the purpose of which is to ensure that the rotation of pulley 51 can drive pulley 54 to rotate via belt 52.

[0043] The number of support shaft 53, pulley 54 and mounting plate 55 is set to two, and they are symmetrical to each other along the vertical central axis of the rotating shaft 42. The top of the collection box 511 is located directly below the discharge pipe 59. The purpose is to ensure that the dried mineral powder can accurately enter the collection box 511.

[0044] For example, such as Figures 1-5 As shown, the heater 57 is started simultaneously with the motor 41. The rotating shaft 42 rotates, driving the pulley 51 to rotate. The rotation of the pulley 51 drives the pulley 54 to rotate via the belt 52. The rotation of the pulley 54 drives the support shaft 53 to rotate. The rotation of the support shaft 53 drives the conveying fan 56 to rotate via the mounting plate 55, thereby generating air pressure. This causes the hot air generated by the heater 57 to be blown by the conveying fan 56 and then enters the housing 43 through the conveying port 58 to contact the separated mineral powder for more effective drying. The dried mineral powder enters the collection box 511 through the open valve 510 and the discharge pipe 59 for collection.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
