Description

Technical Field

[0001] This utility model belongs to the technical field of fuel vibration separation equipment, specifically a fuel vibration separation device for sintering machines. Background Technology

[0002] In the sintering production process of the iron and steel metallurgical industry, sintering fuel plays a crucial role. Currently, the fuel used in sintering is usually processed together with iron-containing raw materials, flux, return ore, and dust. These materials are first thoroughly mixed in a mixer, then granulated by a granulator, and finally transported to a mixing silo. Next, the mixture is evenly distributed onto the sintering machine trolley using mud rollers, wide belts, or multi-roller distributors. To achieve uniform distribution of sintering fuel on the sintering machine material surface, a fuel distribution device for the sintering machine material surface is required.

[0003] Chinese patent CN212645373U discloses a split adjustable arc-shaped flat plate for a sintering machine. This plate is divided into three parts: a straight flat plate in the middle and arc-shaped flat plates on both sides. This design addresses the requirements of a thinner material layer in the middle of the sintering machine's width direction due to poor air permeability, and a larger material layer at the edges to suppress edge effects. The goal is to achieve a flat material surface that is both arc-shaped and consistent with the sintering speed in the width direction of the trolley, thus perpendicular to the sintering speed. However, this design requires a high degree of removal of impurities from the sintering fuel particle size. Medium and large particles of fuel, as well as impurities introduced during fuel transport, can easily cause jamming of the fuel distribution device on the sintering machine's material surface and damage to structural components, leading to high maintenance frequency and severely impacting production efficiency. This design fails to meet the requirement for continuous and uniform material distribution in the sintering machine's fuel distribution device.

[0004] Therefore, there is an urgent need for a sintering machine fuel vibration separation device to vibrate and separate medium and large-sized fuel and impurities, prevent medium and large-sized fuel and impurities from causing jamming of the fuel distribution device on the sintering machine material surface, avoid damage to the structure of the distribution device, and meet the use requirements of continuous and uniform distribution of fuel on the sintering machine material surface fuel distribution device. Utility Model Content

[0005] The purpose of this invention is to provide a sintering machine fuel vibration separation device to solve at least one aspect of the problems and defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A sintering machine fuel vibration separation device, comprising: The dust collection mechanism, the vibration separation mechanism, and the debris separation mechanism are connected at the bottom to the top of the vibration separation mechanism. The dust collection mechanism includes a cover, with a dust suction port on one side and a feed inlet on the other side. The vibration separation mechanism includes a housing and a vibration assembly disposed within the housing; The debris separation mechanism is located on one side of the housing; The vibration component is connected to the debris separation mechanism.

[0007] The sintering machine fuel vibration separation device according to the present invention has at least the following technical effects: This sintering machine fuel vibration separation device adds fuel to the sintering machine material surface through the feed inlet of the dust collection mechanism. The fuel falls into the vibration separation mechanism for the vibration separation of medium and large particle sizes and impurities. The unqualified medium and large particle sizes and impurities after screening are recovered through the impurity separation mechanism, while the qualified particle sizes of the fuel after screening are used in the sintering machine material surface fuel distribution device. This effectively prevents medium and large particle sizes and impurities from causing jamming on the sintering machine material surface fuel distribution device, avoids damage to the distribution device structure, ensures the stable operation of the sintering machine material surface fuel distribution device, reduces production interruptions caused by equipment failures, reduces maintenance time and costs, thereby improving production efficiency and meeting the requirements of the sintering machine material surface fuel distribution device for continuous and uniform fuel distribution.

[0008] As a further embodiment of this utility model: the vibration assembly includes a screen box and a discharge trough. The screen box is connected to the feed inlet. One end of the screen box is connected to the inner wall of the housing, and the other end is connected to the discharge trough. The discharge trough is connected to the debris separation mechanism.

[0009] As a further embodiment of this utility model: the end of the screen box away from the discharge chute is higher than the end of the screen box near the discharge chute.

[0010] As a further embodiment of this utility model: a screen is provided along the length of the screen box, and a buffer block is provided at one end of the screen near the discharge chute.

[0011] As a further embodiment of this utility model: a screening hopper is provided at the bottom of the screening box, and a vibration motor is provided on one side of the screening hopper.

[0012] The vibrating assembly includes a screen box and a discharge chute. The screen box is connected to the feed inlet, one end of the screen box is connected to the inner wall of the shell, and the other end is connected to the discharge chute. The discharge chute is connected to the debris separation mechanism. The end of the screen box away from the discharge chute is higher than the end of the screen box near the discharge chute. A screen mesh is provided along the length of the screen box, and a buffer block is provided at the end of the screen mesh near the discharge chute. A screening hopper is provided at the bottom of the screen box, and a vibrating motor is provided on one side of the screening hopper.

[0013] During operation, after fuel is added through the feed inlet of the dust collection mechanism, it falls onto the screen inside the screen box. The fuel, passing through the inclined screen box and using the vibration of the vibrating motor, rolls along the bottom of the screen box. During this rolling motion, fuel particles suitable for the sintering machine's fuel distribution device are sieved and fall into the screen hopper. Medium and large particles, as well as impurities, cannot be sieved and continue rolling towards the bottom of the screen box, falling into the discharge chute and being discharged through the impurity separation mechanism. Simultaneously, the buffer block effectively blocks granular fuel that has not yet been screened and meets the requirements of the sintering machine's fuel distribution device, allowing it to be screened into the hopper through continuous vibration. Furthermore, the buffer block does not interfere with the flow of medium and large granular fuel and impurities from the screen into the discharge chute. This device effectively achieves efficient separation of fuels and impurities of different granular sizes, ensuring the screening rate of qualified granular fuel, reducing waste of qualified fuel, and guaranteeing the size and quality of fuel entering the sintering machine's fuel distribution device, thereby meeting the continuous and uniform distribution requirements of the sintering machine's fuel distribution device.

[0014] As a further embodiment of this utility model: a base plate is provided inside the housing, and buffer support columns are respectively provided at the top of the base plate and the bottom of the screen box, and at the top of the base plate and the bottom of the discharge trough.

[0015] By setting a base plate inside the housing, and setting buffer support columns at the top of the base plate and the bottom of the screen box, as well as at the top of the base plate and the bottom of the discharge trough, a large impact force is generated when fuel falls from the feed inlet into the screen box, from the screen into the discharge trough or screen hopper, and when the vibrating motor vibrates. The buffer support columns can greatly reduce the impact force generated when the fuel falls, avoid the entire device from shaking or swaying violently due to excessive impact force, effectively reduce the probability of device failure, and ensure long-term stable operation of the equipment.

[0016] As a further embodiment of this utility model: a discharge plate is provided along the top periphery of the substrate, and the discharge plate is set at an angle of 50°-70° with the shell.

[0017] Dust is inevitably generated during fuel screening and conveying. If dust accumulates on the substrate, it will not only affect the cleanliness of the equipment but may also enter various components, leading to equipment malfunctions. By installing a discharge plate around the top of the substrate at a 50°-70° angle to the housing, dust can slide off the discharge plate, preventing dust accumulation on the substrate, reducing equipment malfunctions caused by dust accumulation, and lowering equipment maintenance costs.

[0018] As a further embodiment of this utility model: the debris separation mechanism includes a separation tube and a collection box disposed at the bottom of the output end of the separation tube.

[0019] Because the impurity separation mechanism includes a separation pipe and a collection box located at the bottom of the output end of the separation pipe, the medium and large particle size fuel and impurities screened into the discharge trough can be separated from the vibrating separation mechanism along the separation pipe and fall into the collection box through the separation pipe. This effectively improves the fuel screening efficiency, prevents the medium and large particle size fuel and impurities screened out from accumulating in the vibrating separation mechanism and causing blockage, and ensures that the screening process continues to be efficient.

[0020] As a further embodiment of this utility model: an inspection window is provided on one side of the housing, and an inspection cover is hinged to the outside of the inspection window.

[0021] As a further embodiment of this utility model: the inspection cover is provided with a pin hole, and the housing is provided with a pin, the pin being adapted to the pin hole.

[0022] By setting an inspection window on one side of the housing, and hinged to the outside of the inspection window, a maintenance cover plate is provided. The maintenance cover plate has a pin hole, and the housing has a pin that matches the pin hole. This allows operators to directly observe the screening of fuel in the vibrating components by opening the maintenance cover plate and looking through the inspection window, enabling them to promptly identify potential faults. Furthermore, when parts are damaged, it is convenient to disassemble and repair them without disassembling the entire housing, greatly shortening maintenance time, improving maintenance efficiency, and reducing equipment downtime.

It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0032] like Figure 1-3The present invention, as shown in this embodiment, provides a sintering machine fuel vibration separation device, comprising: a dust collection mechanism 1, a vibration separation mechanism 2, and a debris separation mechanism 3. The bottom of the dust collection mechanism 1 is connected to the top of the vibration separation mechanism 2. The dust collection mechanism 1 includes a cover 101, with a dust suction port 102 on one side and a feed inlet 103 on the other side. The vibration separation mechanism 2 includes a housing 201 and a vibration component disposed within the housing 201. The debris separation mechanism 3 is disposed on one side of the housing 201. The vibration component is connected to the debris separation mechanism 3.

[0033] Specifically, the sintering machine fuel vibration separation device adds fuel to the sintering machine material surface through the feed inlet 103 of the dust collection mechanism 1. The fuel falls into the vibration separation mechanism 2 for vibration separation of medium and large particle size fuel and impurities. The unqualified medium and large particle size fuel and impurities after screening are recovered through the impurity separation mechanism 3, and the qualified particle size fuel after screening is used in the sintering machine material surface fuel distribution device. This can effectively prevent medium and large particle size fuel and impurities from causing jamming of the sintering machine material surface fuel distribution device, avoid damage to the structure of the distribution device, ensure the stable operation of the sintering machine material surface fuel distribution device, reduce production interruptions caused by equipment failure, reduce maintenance time and costs, thereby improving production efficiency and meeting the requirements of the sintering machine material surface fuel distribution device for continuous and uniform fuel distribution.

[0034] Furthermore, the vibration assembly includes a screen box 202 and a discharge chute 203. The screen box 202 is connected to the feed inlet 103. One end of the screen box 202 is connected to the inner wall of the housing 201, and the other end is connected to the discharge chute 203. The discharge chute 203 is connected to the debris separation mechanism 3. The end of the screen box 202 away from the discharge chute 203 is higher than the end of the screen box 202 near the discharge chute 203. A screen mesh 204 is provided along the length of the screen box 202. A buffer block 205 is provided on the end of the screen mesh 204 near the discharge chute 203. A screening hopper 206 is provided at the bottom of the screen box 202, and a vibration motor 207 is provided on one side of the screening hopper 206.

[0035] In use, after fuel is added through the feed inlet 103 of the dust collection mechanism 1, the fuel falls onto the screen 204 inside the screen box 202. The fuel, passing through the inclined screen box 202 and screen 204, and vibrated by the vibration force of the vibrating motor 207, rolls along the bottom of the screen box 202. During this rolling process, fuel of the appropriate particle size for the sintering machine's fuel distribution device is screened through the screen 204 and falls downwards into the screen hopper 206, while fuel of the appropriate particle size for the sintering machine's fuel distribution device is not. Particle-sized fuel and impurities that cannot be screened by screen 204 continue to roll toward the bottom of screen box 202 and fall into discharge chute 203, and are discharged outward through impurity separation mechanism 3; at the same time, buffer block 205 can effectively block the particle-sized fuel that has not yet been screened by screen 204 and meets the requirements of the sintering machine material surface fuel distribution device, so that it is eventually screened into screen hopper 206 by screen 204 through continuous vibration; and buffer block 205 will not interfere with the falling of medium and large particle-sized fuel and impurities from screen 204 into discharge chute 203.

[0036] Specifically, the device effectively achieves efficient separation of fuels and impurities of different particle sizes, ensures the screening rate of qualified particle size fuels, reduces the waste of qualified fuels, and guarantees the size and quality of fuel entering the fuel distribution device on the sintering machine material surface, thereby meeting the requirements of continuous and uniform material distribution on the sintering machine material surface fuel distribution device.

[0037] Furthermore, such as Figure 3 As shown, a base plate 208 is provided inside the housing 201, and buffer support columns 209 are respectively provided at the top of the base plate 208 and the bottom of the screen box 202, and at the top of the base plate 208 and the bottom of the discharge trough 203.

[0038] Specifically, by setting a base plate 208 inside the housing 201, and setting buffer support columns 209 at the top of the base plate 208 and the bottom of the screen box 202, and at the top of the base plate 208 and the bottom of the discharge trough 203 respectively, a large impact force will be generated when fuel falls from the feed inlet 103 into the screen box 202, when fuel falls from the screen 204 into the discharge trough 203 or the screen hopper 206, and when the vibrating motor 207 vibrates. The buffer support columns 209 can greatly reduce the impact force generated when fuel falls, avoid the entire device from shaking or swaying violently due to excessive impact force, effectively reduce the probability of device failure, and ensure long-term stable operation of the equipment.

[0039] Furthermore, a discharge plate 210 is provided along the top periphery of the substrate 208, and the discharge plate 210 is set at an angle of 50°-70° with the housing 201.

[0040] Specifically, dust is inevitably generated during fuel screening and conveying. If dust accumulates on the substrate 208, it will not only affect the cleanliness of the equipment, but may also enter various components of the equipment, leading to equipment failure. By providing a discharge plate 210 around the top of the substrate 208, with the discharge plate 210 at a 50°-70° angle to the housing 201, dust can slide off along the discharge plate 210, avoiding dust accumulation on the substrate, reducing equipment failures caused by dust accumulation, and lowering equipment maintenance costs.

[0041] Furthermore, such as Figure 1 As shown, the debris separation mechanism 3 includes a separation tube 301 and a collection box disposed at the bottom of the output end of the separation tube 301.

[0042] Specifically, since the impurity separation mechanism 3 includes a separation pipe 301 and a collection box located at the bottom of the output end of the separation pipe 301, the medium and large particle size fuel and impurities screened into the discharge trough 203 can be separated out of the vibration separation mechanism 2 along the separation pipe 301 and fall into the collection box through the separation pipe 301. This effectively improves the fuel screening efficiency, prevents the medium and large particle size fuel and impurities screened out from accumulating in the vibration separation mechanism 2 and causing blockage, and ensures that the screening process continues to be carried out efficiently.

[0043] According to embodiments of the present invention, such as Figure 1 As shown, a maintenance window is provided on one side of the housing 201, and a maintenance cover plate 211 is hinged to the outside of the maintenance window; a pin hole is provided on the maintenance cover plate 211, and a pin 212 is provided on the housing 201, with the pin 212 matching the pin hole.

[0044] Specifically, an inspection window is provided on one side of the housing 201, and an inspection cover 211 is hinged to the outside of the inspection window. The inspection cover 211 is provided with a pin hole, and the housing 201 is provided with a pin 212, which is adapted to the pin hole. This allows the operator to directly observe the screening of fuel in the vibrating component by opening the inspection cover 211 and through the inspection window, so as to discover potential faults in time. In addition, when parts are damaged, it is convenient to disassemble and repair them without disassembling the entire housing, which greatly shortens the maintenance time, improves maintenance efficiency, and reduces equipment downtime.

[0045] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
