Abstract
Description
Technical Field
[0001] This utility model belongs to the field of screening and dust removal technology, and more specifically, it relates to a dust control device for the screening process of high-temperature materials. Background Technology
[0002] In the field of high-temperature material handling, dust generation during material transfer and screening in high-temperature environments is a prominent issue. Especially in the high-temperature screening stage, because vibrating screening devices are typically not completely sealed, a large amount of high-temperature dust is generated when high-temperature materials enter the equipment for screening, resulting in a harsh environment around the equipment. This not only affects the normal operation and maintenance of the equipment but may also harm the health of operators.
[0003] Currently, a common method for dust control during high-temperature material screening is to fully seal the screening device before implementing dust removal. This method, when the screening device has a sealed outer shell, can control and manage dust to a certain extent by adding dust collection equipment to the sealed shell. However, for screening devices without a sealed outer shell, even with partial sealing measures, dust leakage still occurs during material entry and exit and equipment vibration, failing to effectively solve the dust problem of incompletely sealed screening devices. Utility Model Content
[0004] The purpose of this invention is to provide a dust control device for high-temperature material screening processes, which addresses the dust problem in non-fully sealed screening devices and improves the production environment.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a dust control device for high-temperature material screening processes, comprising:
[0006] The screening device body includes an upper screen body and a lower screen body arranged vertically, with a circumferential gap between the upper screen body and the lower screen body. A material inlet is provided on one side of the upper screen body, and a material outlet is provided on the other side of the upper screen body. A dust removal pipe is provided on the top of the upper screen body.
[0007] A flexible connection structure, comprising an inlet flexible connection, an outlet flexible connection, and a dust removal flexible connection, wherein the inlet flexible connection is disposed at the material inlet, the outlet flexible connection is disposed at the material outlet, and the dust removal flexible connection is disposed at the dust removal pipe;
[0008] A rigid connection structure is provided within the circumferential gap. The rigid connection structure includes an upper connecting plate connecting the upper screen body and a lower connecting plate connecting the lower screen body. An overlapping area is formed between the upper connecting plate and the lower connecting plate to prevent dust leakage.
[0009] In one possible implementation, the inlet flexible connector is an inlet flexible connector tube made of high-temperature resistant canvas material, which is used to connect to the feeding equipment.
[0010] In one possible implementation, the outlet flexible connector is an outlet flexible connector tube made of high-temperature resistant canvas material, which is used to connect to the discharge pipe.
[0011] In one possible implementation, the dust removal flexible connector is a metal dust removal flexible connector tube, which is used to connect to the dust discharge pipe.
[0012] In one possible implementation, the upper end of the upper connecting plate is fixed to the lower circumferential end of the upper screen body, and the lower end of the lower connecting plate is fixed to the upper circumferential end of the lower screen body, with the lower part of the upper connecting plate and the upper part of the lower connecting plate forming the overlapping area.
[0013] In one possible implementation, the upper connecting plate includes a first horizontal plate and a first vertical plate, with one inner end of the first horizontal plate fixed to the lower end of the upper screen body, and the upper end of the first vertical plate connected to one outer end of the first horizontal plate.
[0014] The lower connecting plate includes a second horizontal plate and a second vertical plate. One outer end of the second horizontal plate is fixed to the upper end of the lower screen body, and the lower end of the second vertical plate is connected to one inner end of the second horizontal plate.
[0015] The first longitudinal plate is located outside the second longitudinal plate, and the lower part of the first longitudinal plate and the upper part of the second longitudinal plate form the overlapping area.
[0016] In one possible implementation, there is an inner gap between the first longitudinal plate and the second longitudinal plate, and a bottom gap between the lower end of the first longitudinal plate and the second transverse plate.
[0017] In one possible implementation, a longitudinal extension plate is fixedly provided at the upper end of the lower screen body, and one outer end of the second transverse plate is vertically fixed to the inner side of the longitudinal extension plate, forming an outer gap between the first longitudinal plate and the longitudinal extension plate.
[0018] In one possible implementation, the upper end of the longitudinal extension plate is higher than the upper end face of the first transverse plate.
[0019] The beneficial effects of the dust control equipment for high-temperature material screening processes provided by this utility model are as follows: The flexible connection structure of the equipment includes an inlet flexible connector, an outlet flexible connector, and a dust removal flexible connector. The inlet flexible connector is located at the material inlet, the outlet flexible connector is located at the material outlet, and the dust removal flexible connector is located in the dust removal pipe. Through these flexible connection structures, a relatively sealed connection is formed at the material inlet and outlet, reducing dust leakage during material entry and exit. When material enters the screening device body, the inlet flexible connector can effectively prevent dust from escaping from the material inlet to the external environment; when material is discharged, the outlet flexible connector can prevent dust from leaking from the outlet. The dust removal flexible connector, located in the dust removal pipe, helps to more effectively collect and treat dust during the dust removal process, reducing the diffusion of dust in the surrounding environment.
[0020] A rigid connection structure is installed within the circumferential gap between the upper and lower screen bodies. This structure includes an upper connecting plate connecting the upper screen body and a lower connecting plate connecting the lower screen body, forming an overlapping area.

[0021] Through the combination of flexible and rigid connection structures, this equipment can better seal the non-fully sealed screening device during material feeding and discharging and equipment vibration, reducing dust leakage. Simultaneously, the dust collection pipe and flexible dust collection connector at the top of the upper screen body help to collect and treat dust effectively and promptly during the screening process, further reducing dust pollution to the environment, ensuring the normal operation of the equipment, reducing harm to the health of operators, and improving the production environment.

[0029] Please see Figure 1 and Figure 2 This invention provides a dust control device for a high-temperature material screening process. The dust control device includes a screening unit body, a flexible connection structure, and a rigid connection structure 6. The screening unit body includes an upper screen body 1 and a lower screen body 2 arranged vertically, with a circumferential gap between them. A material inlet is located on one side of the upper screen body 1, and a material outlet is located on the other side. A dust removal pipe is located at the top of the upper screen body 1. The flexible connection structure includes an inlet flexible connector, an outlet flexible connector, and a dust removal flexible connector. The inlet flexible connector is located at the material inlet, the outlet flexible connector is located at the material outlet, and the dust removal flexible connector is located in the dust removal pipe. The rigid connection structure 6 is located within the circumferential gap and includes an upper connecting plate connecting the upper screen body 1 and a lower connecting plate connecting the lower screen body 2. An overlapping area is formed between the upper and lower connecting plates to prevent dust leakage.
[0030] This utility model provides a dust control device for high-temperature material screening processes. Compared with existing technologies, the device's flexible connection structure includes an inlet flexible connector, an outlet flexible connector, and a dust removal flexible connector. The inlet flexible connector is located at the material inlet, the outlet flexible connector is located at the material outlet, and the dust removal flexible connector is located in the dust collection pipe. These flexible connection structures form a relatively sealed connection at the material inlet and outlet, reducing dust leakage during material entry and exit. When material enters the screening device body, the inlet flexible connector effectively prevents dust from escaping from the material inlet to the external environment; when material is discharged, the outlet flexible connector prevents dust leakage from the outlet. The dust removal flexible connector, located in the dust collection pipe, helps to more effectively collect and treat dust during the dust removal process, reducing the diffusion of dust in the surrounding environment.
[0031] A rigid connection structure 6 is disposed within the circumferential gap between the upper screen body 1 and the lower screen body 2, including an upper connecting plate connecting the upper screen body 1 and a lower connecting plate connecting the lower screen body 2, forming an overlapping area between the upper connecting plate and the lower connecting plate of the lower screen body 2. During equipment vibration, this overlapping area can prevent dust from leaking from the circumferential gap, reduce fugitive dust emissions, lower the dust concentration in the surrounding environment, and thus improve the production environment.
[0032] Through the cooperation of the flexible and rigid connection structures 6, this equipment can better seal the non-fully sealed screening device during material feeding and discharging and equipment vibration, reducing dust leakage. Simultaneously, the dust collection pipe and flexible dust collection connector at the top of the upper screen body 1 help to collect and treat dust effectively and promptly during the screening process, further reducing dust pollution to the environment, ensuring the normal operation of the equipment, reducing harm to the health of operators, and improving the production environment.
[0033] Specifically, the inlet flexible connector is an inlet flexible connector pipe 3 made of high-temperature resistant canvas, which is used to connect to the feeding equipment. The outlet flexible connector is an outlet flexible connector pipe 4 made of high-temperature resistant canvas, which is used to connect to the discharge pipe. The dust removal flexible connector is a dust removal flexible connector pipe 5 made of metal, which is used to connect to the dust discharge pipe.
[0034] During the high-temperature material screening process, this equipment achieves multiple beneficial effects through the combination and synergistic operation of flexible connectors made of different materials. The inlet flexible connector 3 and outlet flexible connector 4, made of high-temperature resistant canvas, effectively resist high temperatures when materials enter and exit the screening device, preventing deformation and damage due to excessive heat. This ensures the stability and sealing of the connection, preventing dust from overflowing from the inlet and outlet during material transport. Simultaneously, the flexibility of the canvas buffers displacement caused by equipment vibration, further reducing dust leakage. It is also wear-resistant, durable, and easy to install, reducing maintenance costs and difficulty. The metal dust collection flexible connector 5, with its robust and durable characteristics, ensures efficient and stable connection between the dust discharge pipe and the dust collection pipe during dust removal, quickly and smoothly collecting and discharging dust generated during screening. These three components work together to create a comprehensive sealing barrier, greatly reducing the spread of dust in the surrounding environment, effectively improving the production environment, ensuring stable equipment operation and the health of operators, while also considering cost-effectiveness and improving enterprise production efficiency.
[0035] Please see Figure 2 The upper end of the upper connecting plate is fixed to the lower circumferential end of the upper screen body 1, and the lower end of the lower connecting plate is fixed to the upper circumferential end of the lower screen body 2. The lower part of the upper connecting plate and the upper part of the lower connecting plate form an overlapping area.
[0036] Specifically, the upper connecting plate includes a first horizontal plate 61 and a first vertical plate 62. The inner end of the first horizontal plate 61 is fixed to the lower end of the upper screen body 1, and the upper end of the first vertical plate 62 is connected to the outer end of the first horizontal plate 61. The lower connecting plate includes a second horizontal plate 63 and a second vertical plate 64. The outer end of the second horizontal plate 63 is fixed to the upper end of the lower screen body 2, and the lower end of the second vertical plate 64 is connected to the inner end of the second horizontal plate 63. The first vertical plate 62 is located outside the second vertical plate 64, and the lower part of the first vertical plate 62 and the upper part of the second vertical plate 64 form an overlapping area.
[0037] Both the upper and lower connecting plates are fixed to the upper screen body 1 and lower screen body 2 respectively via a combination of horizontal and vertical plates, ensuring reliable connection and withstanding equipment vibration and various forces during material handling. The overlapping area formed by the first vertical plate 62 and the second vertical plate 64 creates a three-dimensional barrier, effectively preventing dust leakage from the circumferential gaps even under continuous vibration. When high-temperature materials move within the screening device, dust is difficult to escape into the external environment through this overlapping area. Combined with the flexible connection structures at the inlet / outlet and dust removal points, this comprehensively blocks the dust propagation path, significantly reducing dust concentration in the surrounding environment and effectively improving the production environment. Furthermore, this structural design does not affect the relative vibration between the upper screen body 1 and lower screen body 2, ensuring normal screening operations while reducing dust erosion of equipment components, extending equipment lifespan, and lowering maintenance frequency and costs. It provides a reliable and efficient solution for dust control during high-temperature material screening.
[0038] The first longitudinal plate 62 and the second longitudinal plate 64 have an inner gap 66, and the lower end of the first longitudinal plate 62 and the second transverse plate 63 have a bottom gap 67. The upper end of the lower screen body 2 is fixedly provided with a longitudinal extension plate 65, and one outer end of the second transverse plate 63 is vertically fixed to the inner side of the longitudinal extension plate 65, forming an outer gap 68 between the first longitudinal plate 62 and the longitudinal extension plate 65.
[0039] The presence of the inner gap 66, bottom gap 67, and outer gap 68 provides buffering and displacement space for components such as the first longitudinal plate 62 and the second longitudinal plate 64 during equipment vibration, preventing wear and damage between components caused by rigid connections, thus ensuring the long-term stable operation of the rigid connection structure 6. When the screening device vibrates, these gaps allow the structure to undergo a certain degree of elastic deformation, which does not affect the normal vibration screening function of the upper screen body 1 and the lower screen body 2, and can continuously suppress dust leakage through the blocking effect of the overlapping area. At the same time, the existence of gaps also facilitates installation, disassembly, and maintenance, reducing the difficulty and time cost of equipment maintenance. The setting of the longitudinal extension plate 65 not only provides a stable installation foundation for the second transverse plate 63 and enhances the structural strength of the lower connecting plate, but also forms an outer gap 68 with the first longitudinal plate 62, further optimizing the dust prevention path. Even if dust passes through the gaps in the overlapping area, it will be difficult to escape due to the change in path and the blocking effect of the gaps. Together with the flexible connection structure, a multi-layered, highly sealed dust prevention system is constructed, effectively improving the screening environment for high-temperature materials and reducing the harm of dust to equipment and operators.
[0040] Specifically, the upper end of the longitudinal extension plate 65 is higher than the upper surface of the first horizontal plate 61. When the screening device vibrates, even if a small amount of dust moves upward due to airflow or other factors, the higher longitudinal extension plate 65 can directly intercept the dust, preventing it from leaking into the external environment through the top area between the upper screen body 1 and the lower screen body 2. In addition, the height advantage of the longitudinal extension plate 65 can also work synergistically with the overlapping area to guide the movement path of dust inside the device, making it easier for the dust removal system to collect. At the same time, this design enhances the structural stability of the connection between the lower connecting plate and the lower screen body 2, better dispersing stress when subjected to equipment vibration and material impact, reducing the risk of component loosening and damage, extending the service life of the equipment, further ensuring the efficient and environmentally friendly operation of the high-temperature material screening process, and significantly improving the production environment.
[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
