Description
Technical Field
[0001] This utility model relates to the field of gasification slag treatment technology, and in particular to a gasification slag grading device. Background Technology
[0002] Coal gasification technology is a key technology in the modern coal chemical industry, but it generates a large amount of coal gasification slag. Statistics show that China's annual coal gasification slag emissions exceed 33 million tons. Currently, stockpiling and landfilling remain the main disposal methods, which not only occupy a large amount of land but also cause soil and water pollution. Furthermore, when used as a co-firing agent in boilers, the high moisture content and insufficient calorific value of the gasification slag limit its blending ratio when used as a cement substitute. Its resource utilization is constrained by the interaction between carbon and ash. Coal gasification slag is typically divided into coarse slag and fine slag; coarse slag has a lower residual carbon content, while fine slag has a higher carbon content. Separating the residual carbon and ash components from the fine gasification slag is crucial for achieving its high-value, reduced-volume, and harmless utilization. Typical gasification slag grading equipment consists of a feeding mechanism, a grading mechanism, and a conveying mechanism. The feeding mechanism buffers the gasification slag raw material through a feed hopper and controls the feeding rate to ensure that the raw material enters the subsequent stages evenly. The grading mechanism separates the material into different grades according to the size of the gasification slag particles using screening force. After grading, the conveying mechanism uses a screw conveyor to transport the gasification slag products of different grades to the corresponding silos. In existing technologies, the grading mechanism of some devices cannot provide continuous and stable power support during operation. This causes the vibration frequency of the grading mechanism to fluctuate and the rotation speed to be inconsistent. Consequently, the gasification slag cannot pass through the grading structure according to the preset trajectory and rhythm during the screening process. Some slag accumulates in the grading area and cannot be graded in a timely manner. Furthermore, due to the inherent viscosity of the gasification slag, some fine slag particles easily adsorb each other and form agglomerates during the screening process. When these agglomerates pass through the screen with the slag flow, they become stuck in the screen holes, causing screen blockage. This not only prevents subsequent gasification slag from passing through the screen normally for grading, but also requires frequent shutdowns for cleaning or replacement of the screen. This not only increases the workload and cost of equipment maintenance, but also significantly reduces production efficiency due to prolonged downtime. Therefore, a gasification slag grading device is proposed to solve the above problems. Utility Model Content
[0003] To overcome the above deficiencies, this utility model provides a gasification slag grading device, which aims to improve the problems in the existing gasification slag screening process, such as the lack of stable power in the grading mechanism leading to intermittent screening action and easy clogging of the screen due to slag agglomeration or jamming, resulting in low screening efficiency and frequent equipment maintenance.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A gasification slag grading device includes a base plate, an installation frame fixedly connected to the rear top side of the base plate, a collection frame fixedly connected to the front top side of the base plate, a grading mechanism and a conveying mechanism provided outside the installation frame. The grading mechanism includes two swing shafts, which are rotatably connected to the outer sides of the base plate. A sliding frame is fixedly connected to the adjacent side of the swing shafts. A support spring is fixedly connected to the rear side of the mounting frame. A lever is fixedly connected to the opposite side of the swing shafts. A connecting frame is rotatably connected to the other end of the lever. A screen is slidably connected inside the sliding frame. Side support springs are fixedly connected to both outer sides of the screen. A collection box is slidably connected to the inner bottom of the base plate. A drive assembly is installed on the rear side of the base plate. A feeding assembly is installed on the top of the base plate. As a further description of the above technical solution: The conveying mechanism includes two mounting shafts, which are rotatably connected to the front inner side of the base plate. A conveyor frame is fixedly connected to the adjacent side of the mounting shafts. A conveyor belt is rotatably connected to the inside of the conveyor frame. A baffle is fixedly connected to the outside of the conveyor belt. A conveying pipe is fixedly connected to the left outer side of the collection frame. An auger is rotatably connected to the inside of the conveying pipe. A protective frame is fixedly connected to the right outer side of the collection frame. A drive motor is fixedly connected to the right outer side of the protective frame. As a further description of the above technical solution: The output end of the drive motor is fixedly connected to a transmission sprocket, the outer right end of the auger conveyor is fixedly connected to a drive sprocket, and a chain is slidably connected inside the protective frame. As a further description of the above technical solution: The inside of the chain is fitted onto the outside of the drive sprocket, and the inside of the chain is fitted onto the outside of the transmission sprocket; As a further description of the above technical solution: The drive assembly includes a protective frame, the outer side of which is threadedly connected to the top rear side of the mounting frame. A dual-head motor is fixedly connected inside the protective frame, and a wave wheel is fixedly connected to the output end of the dual-head motor. The wave wheel is slidably connected to the top outer side of the connecting frame. As a further description of the above technical solution: The feeding assembly includes a feeding frame, the bottom of which is fixedly connected to the top of the mounting frame, and a distributing plate is fixedly connected inside the feeding frame. As a further description of the above technical solution: The outer front end of the conveyor frame is supported on the top outside of the collection frame, and the front end of the sliding frame is supported on the outer rear end of the conveyor frame. As a further description of the above technical solution: The top of the support spring is supported on the bottom rear side of the sliding frame, and the opposite side of the side support spring is supported inside the sliding frame.
[0005] This utility model has the following beneficial effects: 1. In this utility model, the drive assembly is activated, and the wave wheel rotates. The wave wheel pushes the connecting frame, which in turn drives the lever and the swing shaft to rotate, causing the sliding frame to swing. The support spring inside the mounting frame supports the sliding frame, causing it to buffer the impact and maintain the swing. The side support spring inside the sliding frame causes the screen to shake slightly, reducing the blockage of the holes. This provides a stable and continuous swinging power for the grading mechanism, reduces the risk of component wear and screen blockage, and ensures the efficient and stable operation of the gasification slag screening process.
[0006] 2. In this utility model, with the cooperation of the mounting shaft and the conveyor frame, the mounting shaft supports the conveyor frame to stably receive the coarse-grained gasification slag sent by the sliding frame. With the cooperation of the conveyor belt and the baffle on the inner side of the conveyor frame, the coarse slag is ensured to fall stably into the collection frame. With the cooperation of the protective frame and the drive motor, the drive motor drives the drive sprocket to rotate through the transmission sprocket and the drive sprocket, providing power for multiple auger conveyors. This solves the problem that the coarse-grained gasification slag is prone to falling during the conveying process due to the offset of the receiving and scattering, and the lack of power for subsequent transfer. It ensures that the entire process of receiving and conveying the coarse slag after screening is stable and orderly. Attached Figure Description

[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0010] Example: A gasification slag grading device, referring to Figure 1 , Figure 3 and Figure 4 The system includes a base plate 1, which serves as the basic load-bearing structure of the equipment and provides stable support for all components above it, preventing displacement due to vibration during operation. A mounting frame 2 is fixedly connected to the top rear side of the base plate 1, forming a semi-enclosed installation space that protects the internal grading mechanism 4. A collection frame 3 is fixedly connected to the top front side of the base plate 1, which can receive the graded gasification slag conveyed by the conveying mechanism 7, preventing the slag from scattering and causing waste. A grading mechanism 4 is installed on the outside of the mounting frame 2, and a three-group grading mechanism 4 is installed inside the mounting frame 2. A conveying mechanism 7 is installed on the outside of the mounting frame 2. The grading mechanism 4 includes two swing shafts 41, which can serve as the rotation fulcrum of the sliding frame 42, enabling the sliding frame 42 to swing back and forth stably. The two swing shafts 41 are rotatably connected to the inside sides of the base plate 1, and the inside sides of the base plate 1 provide rotational support for the swing shafts 41, ensuring that the swing shafts 41 rotate without jamming. The sliding frame 42 is fixedly connected to the adjacent side of the swing shafts 41. The sliding frame 42 can accommodate the screen 46 and drive it to swing synchronously, while providing installation space for the side support spring 47. The support spring 43 is fixedly connected to the rear side of the mounting frame 2. The support spring 43 can provide elastic support for the sliding frame 42, buffer the impact force generated when the sliding frame 42 swings, and provide upward support force to make it swing continuously and extend the service life of the components. A lever 44 is fixedly connected to each of the opposite sides of the swing shaft 41. The lever 44 can convert the movement of the connecting frame 45 into the rotational power of the swing shaft 41, thereby realizing the swinging action of the sliding frame 42. The other end of the lever 44 is rotatably connected to the connecting frame 45. The connecting frame 45 can bear the driving force of the drive component 5 and transmit it to the lever 44 to ensure continuous power transmission. A screen 46 is slidably connected inside the sliding frame 42. The holes of each set of screens 46 are different, and different hole diameters can be used to achieve particle size classification of gasification slag. Side support springs 47 are fixedly connected to both sides of the screen 46. The side support springs 47 can generate lateral elastic force on the screen 46, causing the screen 46 to swing inside the sliding frame 42. A collection box 48 is slidably connected to the bottom inner side of the bottom plate 1. The collection box 48 can receive the fine-grained gasification slag separated by the screen 46. The slidable connection facilitates subsequent removal and cleaning. A drive assembly 5 is installed on the rear side of the base plate 1. The drive assembly 5 provides a power source for the grading mechanism 4 to ensure continuous and stable screening operation. A feeding assembly 6 is installed on the top of the base plate 1. The feeding assembly 6 can evenly introduce the gasification slag to be graded into the grading mechanism 4 to avoid slag accumulation affecting the screening effect. The top of the support spring 43 is supported on the bottom rear side of the sliding frame 42, so that the rear side of the sliding frame 42 is supported by the elastic force of the support spring 43, ensuring stability during swing. The opposite side of the side support spring 47 is supported inside the sliding frame 42. The internal structure of the sliding frame 42 provides a reaction force for the side support spring 47, ensuring the support effect of the side support spring 47 on the screen 46. Specifically, the base plate 1 provides stable support for all components of the equipment, preventing displacement due to vibration during operation. The mounting frame 2 on the rear top of the base plate 1 forms a semi-enclosed space, which protects the internal three-group grading mechanism 4. The collection frame 3 on the front top of the base plate 3 receives the graded gasified slag conveyed by the conveying mechanism 7, preventing the slag from scattering and being wasted. In the grading mechanism 4, the two swing shafts 41 serve as the rotation fulcrum of the sliding frame 42, ensuring that the sliding frame 42 swings back and forth stably. The two sides inside the base plate 1 provide rotational support for the swing shafts 41, preventing the swing shafts 41 from getting stuck during rotation. The sliding frame 42 accommodates the screen 46 and drives it to swing synchronously, and also provides installation space for the side support spring 47. The support spring 43 on the rear inside the mounting frame 2 provides elastic support for the sliding frame 42, buffers the impact force of the swing of the sliding frame 42 and provides upward support force, maintaining its continuous swing and extending the service life of the components. The lever 44 on the opposite side of the swing shaft 41 converts the motion of the connecting frame 45 into the rotational power of the swing shaft 41, realizing the swing of the sliding frame 42. The connecting frame 45 receives the driving force of the drive assembly 5 and transmits it to the lever 44, ensuring continuous power transmission. The screen 46 inside the sliding frame 42 achieves particle size classification of gasification slag through different holes. The side support springs 47 on both sides of the screen 46 generate lateral elastic force on the screen 46, causing the screen 46 to sway inside the sliding frame 42. The collection box 48 on the inner side of the bottom of the bottom plate 1 receives the fine-grained gasification slag separated by the screen 46. The sliding connection facilitates subsequent removal and cleaning. The drive component 5 on the rear side of the base plate 1 provides power to the grading mechanism 4, ensuring continuous and stable screening action. The top feed component 6 evenly introduces the gasification slag to be graded into the grading mechanism 4, avoiding slag accumulation that affects the screening effect. The top of the support spring 43 supports the bottom rear side of the sliding frame 42, so that the rear side of the sliding frame 42 is subjected to elastic support force, ensuring stable swing. The side support spring 47 is supported on the opposite side inside the sliding frame 42, and provides reaction force with the help of the internal structure of the sliding frame 42, ensuring the support effect on the screen 46.
[0011] The drive assembly 5 includes a protective frame 51, which isolates the dual-head motor 52 from the external environment to prevent gasification slag dust from entering the motor and affecting its operation. The external thread of the protective frame 51 is connected to the top rear side of the mounting frame 2, which facilitates the disassembly of the protective frame 51 for maintenance of the internal components. The dual-head motor 52 is fixedly connected inside the protective frame 51. The dual-head motor 52 can provide power to two wave wheels 53 at the same time to ensure balanced driving force on both sides. The output end of the dual-head motor 52 is fixedly connected to the wave wheel 53. When the wave wheel 53 rotates through its own wave-shaped structure, it can push the connecting frame 45 to move up and down, which is then converted into the swinging power of the grading mechanism 4. The external sliding connection of the wave wheel 53 is on the top outer side of the connecting frame 45. The feeding assembly 6 includes a feeding frame 61, which forms a guiding channel so that the gasification slag to be graded can fall accurately above the screen 46. The bottom of the feeding frame 61 is fixedly connected to the top of the mounting frame 2. A distribution plate 62 is fixedly connected inside the feeding frame 61. The distribution plate 62 can disperse the gasification slag in the feeding frame 61 into multiple streams, preventing the slag from accumulating in a certain area of the screen 46 and ensuring uniform screening. Specifically, the protective frame 51 of the drive component 5 isolates the dual-head motor 52 from the external environment, preventing gasification slag dust from entering the motor and affecting its operation. The protective frame 51 also facilitates disassembly for maintenance of internal components. The dual-head motor 52 inside the protective frame 51 simultaneously powers two wave wheels 53, ensuring balanced driving force on both sides. The wave wheels 53 at the output end of the dual-head motor 52, with their wave-shaped structure, drive the connecting frame 45 up and down when rotating, converting the power into the oscillating power of the grading mechanism 4. The sliding connection between the wave wheel 53 and the top outer side of the connecting frame 45 ensures smooth power transmission. The feed frame 61 of the feed component 6 forms a guiding channel, allowing the gasification slag to be graded to fall accurately above the screen 46. The distribution plate 62 inside the feed frame 61 disperses the gasification slag in the frame into multiple strands, preventing the slag from accumulating in a certain area of the screen 46 and ensuring a uniform and efficient screening process.
[0012] Reference Figure 2 , Figure 3 and Figure 5 The conveying mechanism 7 includes two mounting shafts 71, which can serve as support points for the conveying frame 72, ensuring that the conveying frame 72 can stably receive the slag material conveyed by the sliding frame 42. The external parts of the mounting shafts 71 are rotatably connected to the front of the inner side of the base plate 1, so that the mounting shafts 71 can be finely adjusted according to the conveying requirements. The conveying frame 72 is fixedly connected to the adjacent side of the mounting shafts 71. The conveying frame 72 can support the conveyor belt 73 and provide it with a running track, ensuring that the conveyor belt 73 rotates smoothly. The conveyor belt 73 is rotatably connected inside the conveying frame 72. The conveyor belt 73 conveys the coarse-grained gasification slag screened by the sliding frame 42 forward through cyclic rotation. A baffle 74 is fixedly connected to the outside of the conveyor belt 73. The baffle 74 can support the gasified slag on the conveyor belt 73 and ensure stable conveying during the conveying process, ensuring the conveying volume. A conveying pipe 75 is fixedly connected to the outside left side of the collection frame 3. The conveying pipe 75 can form a closed channel, which facilitates the auger conveyor 76 to convey the slag in the collection frame 3 to the outside. The auger conveyor 76 is rotatably connected inside the conveying pipe 75. The auger conveyor 76 can stably convey the gasified slag in the collection frame 3 to the designated position through the rotation of the spiral blades, avoiding slag blockage. A protective frame 77 is fixedly connected to the outside right side of the collection frame 3. The protective frame 77 can wrap the transmission sprocket 79, chain 711 and drive sprocket 710 and other components to prevent accidental injury to the operator during operation, and at the same time prevent dust from adhering and affecting the transmission effect. A drive motor 78 is fixedly connected to the outside right side of the protective frame 77. The drive motor 78 provides the power source for the auger conveyor 76 and ensures the continuous operation of the auger conveyor 76. A drive sprocket 79 is fixedly connected to the output end of the drive motor 78. The drive sprocket 79 can transmit the power of the drive motor 78 to the drive sprocket 710 through the chain 711. The drive sprocket 710 is fixedly connected to the outer right end of the auger conveyor 76. The drive sprocket 710 can convert the power transmitted by the chain 711 into the rotational power of the auger conveyor 76. The chain 711 is slidably connected inside the protective frame 77. The chain 711 serves as a power transmission medium, enabling the power connection between the drive sprocket 79 and the drive sprocket 710. The inside of the chain 711 is sleeved on the outside of the drive sprocket 710. In this configuration, the drive sprocket 710 can stably drive the chain 711. The chain 711 is fitted inside the transmission sprocket 79, so that the rotation of the transmission sprocket 79 can synchronously drive the chain 711 to rotate cyclically. The outer front end of the conveyor frame 72 is supported on the top outer side of the collection frame 3. This support method allows the slag conveyed by the conveyor belt 73 to fall accurately into the collection frame 3. The front end of the sliding frame 42 is supported on the outer rear end of the conveyor frame 72, ensuring that the coarse slag after screening by the sliding frame 42 can smoothly slide onto the conveyor belt 73 of the conveyor frame 72, achieving seamless connection between screening and conveying. Specifically, the two mounting shafts 71 of the conveying mechanism 7 serve as support points for the conveying frame 72, ensuring that the conveying frame 72 stably supports the slag conveyed by the sliding frame 42. It can also finely adjust the angle according to the conveying requirements. The conveying frame 72 on the side of the mounting shaft 71 that is close to the conveying frame 72 supports the conveyor belt 73 and provides a running track, ensuring that the conveyor belt 73 rotates smoothly. The conveyor belt 73 inside the conveying frame 72 conveys the coarse-grained gasification slag after screening by the sliding frame 42 forward through the cyclic rotation. The baffle 74 outside the conveyor belt 73 ensures that the gasification slag on the conveyor belt 73 is stably conveyed during the conveying process, ensuring the conveying volume. The conveying pipe 75 on the left side of the outside of the collection frame 3 forms a closed channel, which facilitates the auger conveyor 76 to convey the slag in the collection frame 3 to the outside. The auger conveyor 76 inside the conveying pipe 75 uses the rotation of the spiral blades to stably convey the gasification slag in the collection frame 3 to the designated position, avoiding slag blockage. The protective frame 77 on the outer right side of the collection frame 3 encloses the transmission sprocket 79, chain 711, and drive sprocket 710, preventing accidental injury to operators during operation and avoiding dust accumulation that could affect transmission efficiency. The drive motor 78 on the outer right side of the protective frame 77 provides power to the auger conveyor 76, ensuring its continuous operation. The transmission sprocket 79 at the output end of the drive motor 78 transmits power to the drive sprocket 710 via the chain 711. The drive sprocket 710 on the outer right side of the auger conveyor 76 converts the power transmitted by the chain 711 into the rotational power of the auger conveyor 76. The chain 711 inside the protective frame 77 serves as a power transmission medium, enabling power connection between the transmission sprocket 79 and the drive sprocket 710. Its placement on the outside of the drive sprocket 710 ensures that the drive sprocket 710 stably drives the chain 711, and its placement on the outside of the transmission sprocket 79 allows the rotation of the transmission sprocket 79 to synchronously drive the chain 711 in a cyclical motion.
[0013] The implementation principle of this application embodiment is as follows: After the equipment is started, the gasification slag to be graded enters from the feed frame 61 of the feed assembly 6, and is dispersed into multiple strands by the distribution plate 62 inside the feed frame 61. The slag falls above the screen 46 of the grading mechanism 4 in the mounting frame 2 to avoid the slag from accumulating. The drive assembly 5 on the rear side of the bottom plate 1 starts to work. The double-head motor 52 in the protective frame 51 drives the wave wheel 53 at the output end to rotate. The wave wheel 53 pushes the connecting frame 45 up and down by sliding with the connecting frame 45. The connecting frame 45 transmits power to the lever 44, causing the lever 44 to swing. Shaft 41 rotates on both sides inside the base plate 1. The swing shaft 41 then drives the sliding frame 42 on the adjacent side to swing. The support spring 43 on the rear side inside the mounting frame 2 provides elastic support for the sliding frame 42, buffers the swing impact force and assists its continuous swing. The screen 46 inside the sliding frame 42 shakes slightly under the lateral elastic force of the side support spring 47. The three sets of screens 46 classify the gasification slag by particle size according to different apertures. The fine gasification slag falls into the collection box 48 on the inner side of the bottom of the base plate 1, while the coarse gasification slag remains on the screen 46 and slides towards the conveying mechanism 7 as the sliding frame 42 swings.
[0014] The mounting shaft 71 of the conveying mechanism 7 supports the conveying frame 72, so that the rear end of the conveying frame 72 receives the coarse gasification slag sent by the sliding frame 42. The conveyor belt 73 inside the conveying frame 72 rotates in a cycle, conveying the coarse slag forward. The baffle 74 outside the conveyor belt 73 ensures stable conveying of the slag. Finally, the coarse slag falls into the collection frame 3 on the front side of the top of the bottom plate 1. The drive motor 78 on the protective frame 77 on the right side of the collection frame 3 starts, driving the transmission sprocket 79 at the output end to rotate. The transmission sprocket 79 transmits power to the drive sprocket 710 on the right side of the auger conveyor 76 through the chain 711 inside the protective frame 77. The drive sprocket 710 drives the auger conveyor 76 to rotate in the conveying pipe 75 on the left side of the collection frame 3. The auger conveyor 76 uses spiral blades to stably convey the coarse slag in the collection frame 3 along the conveying pipe 75 to the designated position, completing the entire gasification slag grading and conveying process.
