Description
Technical Field
[0001] The present application relates to the technical field of material conveying, and in particular to a batching device and a material conveying system. Background Art
[0002] In the fields of metallurgy, mining, coal, building materials or energy, material conveying systems are involved. In the material conveying system, batching equipment needs to be set up to feed the materials to the belt conveyor through the batching equipment.
[0003] A type of batching equipment that is currently widely used is a disc feeder. The disc feeder is driven by an electric motor to rotate the disc. The discharge port is located at the edge of the disc. A scraper can also be provided to facilitate scraping the material onto the belt of the belt conveyor.
[0004] However, the discharge port of the disc feeder is located at the edge of the disc, which is off the center of the silo, causing the belt conveyor to deviate from the center, which will increase the workshop area and increase costs. In addition, in actual applications, it is found that the scraper can only scrape the material around the disc, and the material in the center of the disc will form a dead material zone. If it cannot be removed for a long time, it will increase the pressure in the silo and the operating load of the disc, thus affecting safety.
[0005] In view of this, how to provide a batching equipment that can at least partially solve the above problems is a technical problem that technical personnel in this field currently need to solve. Utility Model Content
[0006] The purpose of the present application is to provide a batching device and a material conveying system. The structural arrangement of the batching device is not easy to form a dead material zone, and the discharge port of the batching device is located in the center of the silo, which is conducive to reducing the footprint of the material conveying system.
[0007] In order to solve the above technical problems, the present application provides a batching equipment, including a silo, a column and a material tray;
[0008] The silo comprises a silo tube and a silo bottom plate arranged at the bottom of the silo tube, the silo tube is a conical tube structure with a larger top and a smaller bottom, and the silo bottom plate is an annular structure with a through hole in the middle;

[0010] The material tray is a bowl-shaped cylinder structure that is larger at the top and smaller at the bottom. The top opening of the material tray is connected to the inner circumferential wall of the silo bottom plate, and the bottom opening of the material tray forms a discharge port.

[0011] By adopting the above scheme, a column is set in the middle area of the silo tube of the conical cylinder structure, and a silo bottom plate of an annular structure is set at the bottom of the silo tube. Through the positional relationship between the column and the relevant structures of the silo, after the material enters the silo, it is in the annular area between the column and the silo tube, and can fall into the material tray below from between the column and the silo bottom plate. Since the material tray is a bowl-shaped cylinder structure with a larger top and a smaller bottom, the material that falls into the material tray is conveniently discharged from the bottom opening of the material tray after being gathered. The probability of material accumulation on the material tray is small, and it is not easy to form a dead material area. In addition, the center line of the bottom opening of the material tray is arranged to coincide with the axial center line of the silo tube. In this way, the discharge port of the batching equipment is located in the center of the silo, and the feeding end of the conveyor can be arranged close to the center of the silo, which is beneficial to reducing the footprint of the material conveying system.
[0012] In a feasible solution, the column portion is in a conical shape, and the radial dimension of the column portion gradually decreases from top to bottom.
[0013] In a feasible solution, the outer peripheral wall of the column portion is provided with ridges.

[0015] In a feasible solution, the column is fixedly connected to the silo through a plurality of connecting plates, one end of the connecting plate is fixedly connected to the inner wall of the silo, and the other end of the connecting plate is fixedly connected to the outer peripheral wall of the column.
[0016] In a feasible solution, the batching equipment further comprises a scraper plate, wherein the scraper plate is located above the bottom plate of the silo, and the scraper plate can rotate around the axial center of the silo to scrape the material onto the material tray.
[0017] In a feasible solution, the batching equipment further comprises a driving mechanism, and the driving mechanism is used for driving the scraper plate to rotate.
[0018] In one feasible solution, the driving mechanism includes a driving source, a reducer and a slewing bearing, the output end of the driving source is transmission-connected to the reducer, the reducer is transmission-connected to the slewing bearing, and the slewing bearing is connected to the scraper plate.
[0019] In a feasible solution, the batching equipment further comprises a discharge sleeve, and the discharge sleeve is sealedly connected to the bottom opening of the material tray.
[0020] The present application also provides a material conveying system, comprising batching equipment and a conveyor, wherein the feed end of the conveyor is located below the discharge port of the batching equipment, and the batching equipment is any of the batching equipment described above.

[0031] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0032] The directional words such as top, bottom, inside and outside mentioned in this article are defined by the positions of the parts in the figure and the positions of the parts relative to each other, just for the sake of clarity and convenience in describing the technical solution. It should be understood that the directional words used in this article should not limit the scope of protection of this patent.
[0033] Please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of a batching device in an embodiment provided in the present application. Figure 2 for Figure 1 Schematic diagram of the structure in the AA direction. Figure 3 for Figure 1 A partial enlarged view of part I in the middle. Figure 1 The local parts are illustrated with cross-section diagrams to clearly show the relevant structures.
[0034] The batching equipment provided in this embodiment can be applied to a material conveying system to feed materials to a conveyor in the material conveying system, and can be applied in the fields of metallurgy, mining, coal, building materials or energy. The batching equipment includes a silo 10 , a column 20 and a tray 30 .
[0035] The silo 10 includes a silo barrel 11 and a silo bottom plate 12, wherein the silo bottom plate 12 is arranged at the bottom of the silo barrel 11; wherein the silo barrel 11 is a conical cylinder structure that is larger at the top and smaller at the bottom, and the silo bottom plate 12 is an annular structure with a through hole in the middle.
[0036] The column 20 is fixed in the middle area of the silo 11. In the axial direction of the silo 10, the column 20 has a certain height. At the position of the column 20, an annular area is formed between the column 20 and the silo 11; in the projection plane perpendicular to the axial center line of the silo, the projection of the column 20 at least covers the projection of the through hole of the silo bottom plate 12; in the axial direction of the silo 10, there is a set distance between the bottom end of the column 20 and the silo bottom plate 12.
[0037] The material tray 30 is a bowl-shaped cylinder structure with a large top and a small bottom, which can also be understood as a conical structure. The material tray 30 has a top opening and a bottom opening. The top opening of the material tray 30 is connected to the inner peripheral wall of the bin bottom plate 12, so that the top opening of the material tray 30 is connected to the inner cavity of the bin tube 11, and the bottom opening of the material tray 30 forms a discharge port. Among them, the center line of the discharge port (i.e., the bottom opening) of the material tray 30 coincides with the axial center line of the bin tube 11.
[0038] It can be understood that there is no gap between the material tray 30 and the bin bottom plate 12 to prevent material from leaking out.
[0039] By adopting the above scheme, a column 20 is set in the middle area of the silo 11 with a conical cylinder structure, and a silo bottom plate 12 with an annular structure is set at the bottom of the silo 11. Through the positional relationship between the column 20 and the relevant structures of the silo 10, after the material enters the silo, it is in the annular area between the column 20 and the silo 11, and can fall into the material tray 30 below from between the column 20 and the silo bottom plate 12. Since the material tray 30 is a bowl-shaped cylinder structure with a larger top and a smaller bottom, the material that falls into the material tray 30 is conveniently discharged from the bottom opening of the material tray 30 after being gathered, and the probability of material accumulation on the material tray 30 is relatively small. The center line of the bottom opening of the material tray 30 is arranged to coincide with the axial center line of the silo 11. In this way, the discharge port of the batching equipment is located in the center of the silo 10, and the feeding end of the conveyor can be arranged close to the center of the silo 10, which is beneficial to reducing the footprint of the material conveying system.
[0040] In one embodiment, the axial centerline of the silo 11, the centerline of the through hole of the silo bottom plate 12, the axial centerline of the column 20, and the axial centerline of the material tray 30 are arranged to coincide with each other. In this way, the structure of the batching equipment is symmetrical, and after the material enters the silo 11, the distribution in the silo 11 and the transportation through the material tray 30 are relatively uniform, which can reduce the probability of forming a dead material zone due to local accumulation of materials.
[0041] In one embodiment, the column 20 is conical in shape, and the radial dimension of the column 20 gradually decreases from top to bottom. Figure 1 After such arrangement, the column 20 can play a certain role in loosening the material falling into the silo 11, making the material relatively loose, which is conducive to the material falling into the material tray 30 and facilitating the discharge of the material.
[0042] In a feasible solution, the outer peripheral wall of the column 20 may also be provided with a ridge 21, which can loosen the material falling into the silo 11 and act as an abrasive, making it more conducive to evenly dispersing the material onto the material tray 30 and sending it out through the material tray 30, which can effectively avoid material piling, is not easy to form dead material areas, and has better material flow smoothness.
[0043] For example, the ridge 21 of the column 20 may be a spiral structure extending spirally around the outer peripheral wall of the column 20, such as Figure 1 In this way, after the material falls into the silo 11, it can slide down along the spiral path formed by the convex ridges 21, and the loosening effect is better.
[0044] In other implementation forms, the convex ridges 21 of the column portion 20 may be in the form of a plurality of annular ridges arranged along the axial direction, or in the form of strip ridges extending along the axial direction, etc.
[0045] In a specific implementation, the height dimension of the column 20 can be smaller than the axial dimension of the silo 11, and the column 20 is arranged close to the bottom of the silo 11, as long as it can loosen the material entering the silo 11 and make the material fall into the annular area where the silo bottom plate 12 is located. The specific value of the height dimension of the column 20 is not limited here.
[0046] In order not to affect the material falling into the material tray 30, there is a set distance in the axial direction between the bottom end of the column 20 and the silo bottom plate 12, and the relative position between the column 20 and the silo barrel 11 can be fixed by a connecting plate 22. Specifically, one end of the connecting plate 22 is fixedly connected to the outer peripheral wall of the column 20, and the other end of the connecting plate 22 is fixedly connected to the inner peripheral wall of the silo barrel 11.
[0047] To ensure the reliability of fixing the column 20, a plurality of connecting plates 22 may be provided, and the plurality of connecting plates 22 may be evenly arranged around the circumference of the column 20. It can be understood that the provision of the connecting plates 22 does not affect the falling of the material into the silo 11.
[0048] In this embodiment, the batching equipment is also provided with a scraper plate 40, which is located above the silo bottom plate 12. The scraper plate 40 can rotate around the axial center of the silo 10 to scrape the material on the silo bottom plate 12 to the material tray 30 and send it out through the material tray 30.
[0049] In one implementation, the batching device is provided with a driving mechanism 50, and the driving mechanism 50 is used to drive the scraper plate 40 to rotate.
[0050] In a specific implementation, the driving mechanism 50 includes a driving source 51, a reducer 52 and a slewing bearing 53. The output end of the driving source 51 is connected to the reducer 52, the reducer 52 is connected to the slewing bearing 53, and the slewing bearing 53 is connected to the scraper 40. When working, the driving source 51 drives the slewing bearing 53 to rotate through the reducer 52, thereby driving the scraper 40 to rotate.
[0051] The slewing bearing 53 is a relatively large bearing capable of bearing a comprehensive load, and can simultaneously bear relatively large axial loads, radial loads and overturning moments.
[0052] The above settings are helpful to improve the reliability of batching equipment operation.
[0053] Specifically, the slewing bearing 53 includes an inner ring component 531, an outer ring component 532 and a rolling body 533 provided between the inner ring component 531 and the outer ring component 532, wherein the inner ring component 531 can be fixed to a fixed structure such as a frame or a cover of the batching equipment, and the outer ring component 532 can rotate relative to the inner ring component 531 driven by the reducer 52. Obviously, the scraper plate 40 is connected to the outer ring component 532 to rotate with the outer ring component 532 to realize the scraping operation.
[0054] In the specific configuration, the center of the slewing bearing 53 also coincides with the axial center line of the silo 10 to ensure the reliability of the overall operation of the batching equipment.
[0055] Exemplarily, the driving source 51 may be an electric motor.
[0056] In specific configuration, the output end of the reducer 52 may be configured as an output gear, and the outer ring component 532 of the slewing bearing 53 may have a tooth structure meshing with the output gear.
[0057] Of course, in other implementations, the output end of the reducer 52 may also be connected to the outer ring component 532 through other transmission structures, such as belt transmission.
[0058] In a feasible solution, a sealed cover can be provided at the connection position between the silo barrel 11 and the silo bottom plate 12 of the silo 10, and at the connection position between the silo bottom plate 12 and the material tray 30, or these positions can be sealed and connected, so that the entire batching equipment has relatively good airtightness to avoid adverse effects on the working environment.
[0059] In this embodiment, the dispensing device is also sealedly connected to a discharge sleeve 60 at the bottom opening of the material tray 30 to facilitate the delivery of the material output from the material tray 30 to a designated location. When the discharge sleeve 60 is provided, the discharge port of the dispensing device is the bottom opening of the discharge sleeve 60.
[0060] The embodiment of the present application also provides a material conveying system, which includes a batching device and a conveyor. The batching device is the batching device introduced in the above embodiment, and the feed end of the conveyor is located below the discharge port of the batching device. Since the discharge port of the batching device is located in the middle area of the batching device, the feed end of the conveyor can be located in the middle area of the batching device, so that the conveyor no longer deviates from the center of the silo, the overall floor space of the material conveying system can be reduced, and the layout in the workshop is also more beautiful.
[0061] During operation, the material is fed into the silo 11 of the silo 10, and the material is loosened under the action of the column 20 in the silo 11, so that the material can fall evenly and dispersedly to the silo bottom plate 12, and the driving mechanism 50 drives the scraper plate 40 to rotate. The scraper plate 40 can scrape the material to the bowl-shaped material tray 30 during the rotation process, and finally fall to the feed end of the conveyor through the material tray 30 and the discharge sleeve 60, and then be transported to the designated position by the conveyor.
[0062] The setting of batching equipment can avoid material piling and is not easy to form dead material areas, making material transportation smoother and ensuring normal and continuous material transportation.
[0063] In a specific implementation, the conveyor of the material conveying system can be a belt conveyor.
[0064] Other structural settings of the material conveying system can be understood by referring to the prior art, and are not the core of the invention of this application and will not be described in detail here.
[0065] Specific examples are used herein to illustrate the principles and implementation methods of the present application, and the description of the above embodiments is only used to help understand the method and core ideas of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
