Abstract
Description
Technical Field
[0001] This utility model relates to the field of material handling technology, and in particular to an activation feeder and a material handling system. Background Technology
[0002] With the continued growth of global energy demand and increasing environmental awareness, the need for efficient collection, screening, and utilization of resources such as coal has significantly increased. Traditional coal mining and material handling methods are no longer sufficient to meet the efficiency, environmental protection, and safety requirements of modern production. Therefore, adopting advanced equipment and technologies, such as tippers and activated feeders, has become crucial for optimizing coal resource processing procedures.
[0003] Existing feeders include two structural forms: vibrating feeders and activated feeders. Vibrating feeders have deep pits and require a large overall investment. Furthermore, for materials with high moisture content, frozen coal, or wet ore, the material is prone to caking on the bottom plate of the vibrating body. Activated feeders, on the other hand, use springs arranged on the sides and bottom to achieve uniform feeding using the principle of sub-resonance.
[0004] However, while existing activated feeding devices can effectively prevent material blockage and ensure continuous and uniform material flow, and can unload bulk materials quickly and efficiently, they cannot lock in materials with good flowability. Coal will continuously slide down one side of the side wall, causing the material to fall to one side of the belt, resulting in belt misalignment or damage. Utility Model Content
[0005] This utility model provides an activated feeder and a material handling system to solve at least one of the above-mentioned technical problems.
[0006] In a first aspect, this utility model provides an activation feeder, comprising:
[0007] frame;
[0008] An activation mechanism is fixed to the frame and has a feed inlet at its top. The activation mechanism is used to activate materials.
[0009] The feeding mechanism is located at the outlet of the activation mechanism. The feeding mechanism includes a gate, a drive assembly, and a feeding channel located directly below the outlet of the activation mechanism. The gate is located between the outlet of the activation mechanism and the feeding channel. The drive assembly can drive the gate to connect or disconnect the outlet of the activation mechanism and the feeding channel.
[0010] In one embodiment, the feeding mechanism further includes a rotating shaft with two ends rotatably disposed at the feed inlet. Two rotating shafts are provided, and two gates are provided. The two gates are respectively fixedly connected to different rotating shafts. The two gates are symmetrically arranged along a first direction. The driving component can drive the gates to rotate circumferentially along the rotating shaft, so that the discharge port of the activation mechanism and the feeding channel are connected or disconnected.
[0011] The first direction is the feeding direction of the material.
[0012] In one embodiment, the driving assembly includes a first driving member, a first connecting member, and two second rotating rods. One end of the first connecting member is rotatably connected to the output end of the first driving member, and the other end is rotatably connected to two different second rotating rods. The ends of the two second rotating rods away from the first connecting member are fixedly connected to different rotating shafts. The first driving member can drive the first connecting member to rotate, so that the two second rotating rods connected to the first connecting member respectively drive the two rotating shafts to rotate.
[0013] In one embodiment, the feeding mechanism further includes a rotating seat, which is fixed to the frame, and the rotating shaft is rotatably connected to the rotating seat.
[0014] In one embodiment, the activation mechanism includes an activation chamber, an activation block, and a vibration assembly. The activation block is located inside the activation chamber, and the vibration assembly can drive the activation chamber to vibrate, so that the activation block activates the material.
[0015] In one embodiment, the excitation assembly includes a frame, an excitation spring, and a second driving member. One end of the excitation spring is connected to the frame, and the other end is connected to the activation chamber. The second driving member is fixed to the frame and is used to drive the excitation spring to excite the activation chamber to vibrate.
[0016] In one embodiment, the activation mechanism further includes a feeding trough disposed in the activation chamber, wherein the cross-section of the inner sidewall of the feeding trough is arc-shaped.
[0017] In one embodiment, the activation feeder further includes a vibration isolation element disposed between the activation mechanism and the frame.
[0018] In one embodiment, the activation feeder further includes a feed hopper, which is disposed on top of the activation mechanism and communicates with the feed inlet of the activation mechanism.
[0019] Secondly, this utility model also provides a material handling system, including the above-mentioned activation feeder, as well as a tipper and a conveyor, wherein the tipper is disposed at the feed end of the activation feeder and the conveyor is disposed at the discharge end of the activation feeder.
[0020] Compared with the prior art, the advantages of this utility model are as follows: the embodiments of this application provide an activation feeder and a material handling system. The activation feeder includes a frame, an activation mechanism, and a feeding mechanism. The activation mechanism is fixed on the frame and is used to activate materials. The feeding mechanism is located at the outlet of the activation mechanism and includes a gate and a drive assembly. On the one hand, when the gate is driven by the drive assembly to disconnect the outlet of the activation mechanism from the feeding channel, materials with good flowability can be locked, thereby better activating the materials. On the other hand, when the gate is driven by the drive assembly to connect the outlet of the activation mechanism with the feeding channel, the size of the feeding channel can be controlled, thereby controlling the amount and position of the falling material. This can prevent excessive material falling and causing excessive impact on the conveyor below, which could damage the conveyor. In addition, it can prevent materials from falling outside the conveyor, thus affecting the material handling efficiency. Attached Figure Description

[0041] The present invention will be further described below with reference to the accompanying drawings.
[0042] Firstly, see Figures 1-4 An embodiment of this application provides an activation feeder, including a frame 1, an activation mechanism 2, and a feeding mechanism 3. The activation mechanism 2 is fixed on the frame 1, and a feed inlet is provided on the top of the activation mechanism 2. The activation mechanism 2 is used to activate materials. The feeding mechanism 3 is provided at the discharge port of the activation mechanism 2. The feeding mechanism 3 includes a gate 31, a drive assembly 32, and a feeding channel provided directly below the discharge port of the activation mechanism 2. The gate 31 is located between the discharge port of the activation mechanism 2 and the feeding channel. The drive assembly 32 can drive the gate 31 to connect or disconnect the discharge port of the activation mechanism 2 and the feeding channel.
[0043] The activation feeder provided in this embodiment can, on the one hand, lock up materials with good flowability when the discharge port of the activation mechanism 2 is disconnected from the feeding channel by the drive component 32 driving the gate 31, thereby better activating the materials. On the other hand, when the discharge port of the activation mechanism 2 is connected to the feeding channel by the drive component 32 driving the gate 31, the size of the feeding channel can be controlled, thereby controlling the amount and position of the falling material. This can prevent excessive material from falling and causing excessive impact on the conveyor 10 below, thus preventing damage to the conveyor 10. In addition, it can prevent the material from falling outside the conveyor 10, which would affect the material processing efficiency.
[0044] It should be noted that in this embodiment, the first direction X is the X direction.
[0045] In this embodiment of the application, the material is mainly coal. However, the activated feeder can also be used to process other powdery or granular materials that are prone to caking, ensuring their flowability and uniform conveying.
[0046] like Figures 2-4 As shown, in some embodiments, the feeding mechanism 3 further includes a rotating shaft 33, with both ends of the rotating shaft 33 rotatably disposed at the feed inlet. There are two rotating shafts 33 and two gate plates 31. The two gate plates 31 are fixedly connected to different rotating shafts 33 respectively. The two gate plates 31 are symmetrically arranged along the first direction X. The driving component 32 can drive the gate plates 31 to rotate circumferentially along the rotating shaft 33, so that the discharge port and the feeding channel of the activation mechanism 2 are connected or disconnected. The first direction X is the feeding direction of the material.
[0047] By rotating the shaft 33 at the feed inlet and fixing the gate 31 to the shaft 33, the gate 31 can be rotated. This allows the drive assembly 32 to drive the gate 31 to rotate circumferentially along the shaft 33 to open or close the feeding channel, thereby locking in materials with good flowability and facilitating better material activation. Furthermore, by arranging the gate 31 in two symmetrically positioned pieces along the first direction X, the gates 31 can be opened and closed in opposite directions, thereby controlling the size of the feeding channel and the amount and position of material falling. This prevents excessive material falling and causing excessive impact on the conveyor 10 below, which could damage the conveyor 10. Additionally, it prevents material from falling outside the conveyor 10, thus affecting the material processing efficiency.
[0048] In this embodiment, in order to ensure that the strength of the gate plate 31 meets the stress requirements, and at the same time to minimize the weight of the gate plate 31 to facilitate installation by maintenance personnel, the rotating shaft 33 is made of φ108X15 Q355B seamless steel pipe. In addition, in order to ensure the wear resistance of the gate plate 31 and to prevent corrosion caused by the water spraying environment, the gate plate 31 is lined with a wear-resistant and corrosion-resistant δ=8mm thick 304 stainless steel plate. Furthermore, in order to further improve the strength of the gate plate 31, multiple reinforcing ribs are evenly arranged on the back of the gate plate 31.
[0049] like Figures 3-4 As shown, in some embodiments, the drive assembly 32 includes a first drive member 321, a first connector 322, and two second rotating rods 323. One end of the first connector 322 is rotatably connected to the output end of the first drive member 321, and the other end is rotatably connected to two different second rotating rods 323. The ends of the two second rotating rods 323 away from the first connector 322 are fixedly connected to different rotating shafts 33. The first drive member 321 can drive the first connector 322 to rotate, so that the two second rotating rods 323 connected to the first connector 322 respectively drive the two rotating shafts 33 to rotate.
[0050] The first driving member 321 drives the first connecting member 322 to rotate, thereby causing the second connecting member to rotate under the drive of the first connecting member 322, which in turn drives the rotating shaft 33 fixedly connected to the second connecting member to rotate, so that the gate 31 rotates to realize the opening and closing of the gate 31.
[0051] In this embodiment, the first driving component 321 is a hydraulic push rod driving component.
[0052] like Figures 2-4 As shown, in some embodiments, the feeding mechanism 3 further includes a rotating seat 34, which is fixed on the frame 1, and the rotating shaft 33 is rotatably connected to the rotating seat 34.
[0053] Specifically, in this embodiment, the first connector 322 is also rotatably connected to a rotating seat 34, which is fixed on the frame 1.
[0054] By setting the rotating seat 34, the rotating shaft 33 and the first connecting member 322 can be provided with stable support, reducing vibration and swaying, ensuring smoother rotation, and the rotating seat 34 can evenly distribute the load borne by the rotating shaft 33, reducing local stress and extending service life. In addition, the rotating seat 34 ensures that the rotating shaft 33 is precisely aligned, reducing eccentricity and swaying, improving rotational accuracy, and greatly increasing the opening and closing size of the gate 31. This allows for control of the size of the feeding channel, controlling the amount and position of material falling, and thus preventing excessive material falling and causing excessive impact on the conveyor 10 below, which could damage the conveyor 10. It also prevents material from falling outside the conveyor 10, affecting the material processing efficiency.
[0055] like Figures 1-2 As shown, in some embodiments, the activation mechanism 2 includes an activation chamber 21, an activation block 22, and a vibration assembly 23. The activation block 22 is located inside the activation chamber 21, and the vibration assembly 23 can drive the activation chamber 21 to vibrate so that the activation block 22 activates the material.
[0056] By fixing the activation block 22 inside the activation chamber 21, it can vibrate together with the activation chamber 21 under the drive of the excitation component 23, thereby activating the material. On the one hand, by using the activation block 22, the material can be crushed or refined, increasing its surface area and thus improving the reaction efficiency. On the other hand, it can effectively prevent the material from agglomerating, improve its fluidity, and facilitate transportation and processing. Furthermore, the activation block 22 makes the material particles more uniform, which helps to achieve better activation and mixing effects.
[0057] like Figures 1-2 As shown, in some embodiments, specifically, the excitation assembly 23 includes a frame 231, an excitation spring 232, and a second driving member 233. One end of the excitation spring 232 is connected to the frame 231, and the other end is connected to the activation chamber 21. The second driving member 233 is fixed on the frame 231 and is used to drive the excitation spring 232 to vibrate so that the activation chamber 21 vibrates.
[0058] By employing the excitation spring 232, which serves as an elastic element, the vibration generated by the second drive component 233 can be efficiently transmitted. Through the synergistic effect of the frame 231, the excitation spring 232, and the second drive component 233, efficient, stable, and controllable vibration transmission is achieved, transmitting the vibration to the activation chamber 21. This causes the activation block 22 to vibrate along with the activation chamber 21, thereby activating the material, making the material particles more uniform, and contributing to better activation and mixing effects.
[0059] like Figures 1-2 As shown, in some embodiments, the activation mechanism 2 further includes a feeding trough 24, which is disposed in the activation chamber 21, and the cross-section of the inner sidewall of the feeding trough 24 is arc-shaped.
[0060] By setting the cross-section of the inner wall of the feeding trough 24 to be arc-shaped, on the one hand, the material flow can be smoother, reducing the risk of blockage. The arc-shaped structure avoids right angles or sharp angles, preventing material accumulation. On the other hand, the arc-shaped structure is easy to clean, reducing material residue. The arc-shaped trough structure is simple, easy to disassemble and maintain. In addition, the arc-shaped trough reduces the wear of material on the trough wall, extending its service life. Furthermore, the inner wall can be made of corrosion-resistant materials, adapting to harsh environments.
[0061] like Figures 1-2 As shown, in some embodiments, the activation feeder further includes a vibration isolation member 4, which is disposed between the activation mechanism 2 and the frame 1.
[0062] By installing a vibration isolator 4 between the activation mechanism 2 and the frame 1, vibration transmission between the activation mechanism 2 and the frame 1 can be avoided. On the one hand, this prevents the frame 1 from vibrating along with the activation mechanism 2, thus preventing instability of the frame 1. On the other hand, the vibration isolator 4 reduces the wear and tear on the equipment caused by vibration, extending its service life. Furthermore, the vibration isolator 4 prevents other mechanisms besides the activation mechanism 2 from being damaged by vibration, ensuring their normal operation. In addition, the vibration isolator 4 reduces dust caused by equipment vibration, keeping the environment clean, and reduces noise generated by vibration, improving the working environment.
[0063] like Figure 1 As shown, in some embodiments, the activation feeder further includes a feed hopper 5, which is disposed on the top of the activation mechanism 2 and communicates with the feed port of the activation mechanism 2.
[0064] By setting up the feed hopper 5, it can serve as a temporary material storage device, storing a certain amount of material in advance during the production process to ensure a continuous and stable material supply to subsequent processing equipment and avoid equipment downtime due to untimely material supply. On the other hand, it can guide the material into the equipment according to the predetermined direction and path, ensuring that the material accurately enters the subsequent processing stage, preventing the material from scattering or deviating from the conveying route, and improving the accuracy and efficiency of material conveying.
[0065] Secondly, one embodiment of this application also provides a material handling system, including the activation feeder described above, and also including a tipper and a conveyor 10. The tipper is disposed at the feed end of the activation feeder, and the conveyor 10 is disposed at the discharge end of the activation feeder.
[0066] The material is fed into the feed hopper 5 of the activation feeder by the tipper, and then activated by the activation mechanism 2. Finally, the material is accurately dropped onto the conveyor 10 by the unloading mechanism 3 to achieve the activation and other treatment of the material.
[0067] In some embodiments, the conveyor 10 includes a conveyor belt 101 and a receiving hopper 102. After the gate 31 opens the discharge channel, the material falls onto the conveyor belt 101, and the conveyor belt 101 moves the material to the storage location for storage. In addition, the receiving hopper 102 is located at the bottom of the conveyor 10 and directly below the discharge channel, so as to catch the material falling from the conveyor belt 101 and avoid material waste.
[0068] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
