A dust falling device for a semi-coke production workshop

Abstract

The present application relates to the field of semi-coke processing, and particularly relates to a semi-coke production workshop dust falling device. The technical problem to be solved is that when the existing device performs dust falling work, water vapor diffuses in the air and affects the artificial vision, and the dust falling area cannot be specified for dust falling, and the dust is easy to form clumps after being humidified, which causes the dust to adhere to the surfaces of the device, resulting in device failure, and thus the dust cannot be collected and dusted. The technical scheme is that a semi-coke production workshop dust falling device comprises a crusher and a dust cover, etc.; a dust cover for blocking semi-coke dust is arranged in front of the crusher. The present application realizes that the water mist sprayer is arranged obliquely, thereby improving the effect of dust humidification and sedimentation on the dust guide plate, preventing irregular dust sedimentation on the conveying belt, reducing the dust falling effect on the rear end of the conveying belt, thereby reducing the air quality in the workshop and ensuring human health.

Description

Technical Field

[0001] This invention relates to the field of semi-coke processing, and more particularly to a dust suppression device for semi-coke production workshops. Background Technology

[0002] Existing dust suppression equipment in workshops typically involves laying numerous water pipes and nozzles above the workshop. The nozzles spray mist of water to humidify the airborne dust, causing it to absorb the water and settle, thus achieving dust suppression. However, existing equipment involves extensive pipework, and the nozzles are prone to dead zones, failing to effectively suppress dust in certain areas. This results in significant water waste. Furthermore, the moisture in the air obstructs visibility during production, increasing the risk to manual operators. Additionally, existing dust suppression equipment often only works after dust has already accumulated in the workshop, failing to target specific dust-generating areas as dust rises, leading to dust hazards to workers' health and significantly increasing production costs and wasting resources.

[0003] Furthermore, dust tends to clump after humidification, causing it to adhere to the surface and crevices of the device. Over time, severe dust accumulation can clog the device, preventing it from operating normally. It is also difficult to clean manually, leading to dust dispersion and preventing the device from effectively suppressing dust. In severe cases, dust explosions may occur, and the dust can also harm the health of operators. Summary of the Invention

[0004] To overcome the shortcomings of existing dust suppression devices, such as moisture affecting visibility and inability to target specific dust-generating areas, as well as dust clumping after humidification leading to adhesion to various surfaces and device malfunctions, thus hindering dust collection and suppression, this invention provides a dust suppression device for semi-coke production workshops.

[0005] The technical solution is as follows: A dust suppression device for a semi-coke production workshop includes a crusher and a dust cover; a dust cover is installed in front of the crusher to prevent semi-coke dust from being emitted; it also includes water mist nozzles, dust guide plates, a leveler, separation plates, and a crushing system; several water mist nozzles are installed inside the dust cover to reduce semi-coke dust; two symmetrical dust guide plates are installed inside the dust cover to collect semi-coke dust; each of the two dust guide plates has a first dust outlet on its rear side to separate the humidified dust from the dust guide plate; a leveler is installed on the rear side of the dust cover to spread the semi-coke dust; two through holes are opened on the front side of the leveler, and the through holes are connected to the adjacent first dust outlet; a second dust outlet is opened at the lower rear side of the leveler; based on a top-down view, the front and rear sides of the leveler gradually converge towards the center, making the front and rear sides of the leveler flared; several separation plates are installed inside the leveler to make the semi-coke spread more evenly; a crushing system for crushing semi-coke dust is installed inside the dust cover.

[0006] As a further preferred option, based on a front-to-back view, two adjacent water mist nozzles are tilted to the left and right sides respectively.

[0007] As a further preferred option, the two dust guide plates are arranged in a figure-eight shape based on a front-to-back view.

[0008] As a further preferred option, taking the middle of the rear side of the leveler as a reference, the rear parts of several separation plates located on the left side of the leveler are bent towards the left side of the leveler, and the rear parts of several separation plates located on the right side of the leveler are bent towards the right side of the leveler.

[0009] As a further preferred embodiment, the crushing system includes an industrial fan, a separation membrane, and a guide block; an industrial fan for guiding dust diffusion is fixedly connected to the front inner side of the dust cover; several separation membranes for crushing dust agglomerates are movably connected to the upper and rear sides of each dust guide plate, and the separation membranes are made of rubber; a guide block for guiding dust diffusion is fixedly connected to the rear side of each dust guide plate.

[0010] As a further preferred option, adjacent separation membranes are staggered when viewed from above.

[0011] As a further preferred option, based on a right-to-front view, the front side of the guide block is set to tilt to the right.

[0012] As a further preferred option, it also includes an air guide; the front sides of the two dust guide plates are jointly fixed with an air guide to prevent the dust at the upper part of the dust guide plates from being disturbed by the airflow.

[0013] As a further preferred option, based on a front-to-back view, the lower front part of the air guide is designed to gradually slope downwards from the middle to the left and right sides.

[0014] As a further preferred option, two inverted triangular blocks that gradually extend backward are provided on the rear side of the air guide.

[0015] The present invention has the following advantages: The present invention achieves the effect of improving the humidification and settling of dust on the dust guide plate by setting the water mist nozzle at an angle, preventing the dust from settling irregularly on the conveyor belt, reducing the dust settling effect at the rear end of the conveyor belt, thereby reducing the air quality in the workshop and ensuring human health. By tilting the dust guide plate, the dust gradually gathers below the water mist nozzle as it moves upward, improving the dust suppression capability of the water mist nozzle and preventing the dust from being insufficiently humidified and spreading into the workshop, thus reducing visibility and preventing dust from obstructing workers' vision, thereby reducing the risk of manual operation. By using the inclined structure on both sides of the rear end of the separation plate, the effect of the flattener in separating and spreading dust is improved, preventing dust from failing to spread evenly on the surface of semi-coke, which would cause dust to be generated during the transportation of semi-coke, leading to a decline in workshop air quality and ensuring human health. While guiding and breaking up dust through the deformation of the separation membrane, the separation membrane also scrapes and disperses agglomerated dust multiple times to prevent dust from clogging the first dust outlet, thereby improving the dust breaking effect and ensuring the normal operation of the device. The inclined structure on the lower side of the air guide directs the dust raised at the front end of the conveyor belt into the dust cover, preventing the industrial fan from failing to effectively extract the dust into the dust cover, which would cause the dust to spread in the workshop, obstructing workers' vision and endangering their health.

Detailed Implementation

[0018] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0019] Example 1 like Figures 2-5 As shown, a dust suppression device for a semi-coke production workshop includes a crusher 1 and a dust cover 2; the dust cover 2 is installed in front of the crusher 1. It also includes water mist nozzles 3, dust guide plates 4, a leveler 5, a separating plate 6, and a crushing system; at least six water mist nozzles 3 are installed inside the dust cover 2; two symmetrical dust guide plates 4 are installed inside the dust cover 2; each of the two dust guide plates 4 has a first dust outlet 4001 on its rear side; a leveler 5 is installed on the rear side of the dust cover 2; two through holes 5001 are opened on the front side of the leveler 5, and the through holes 5001 are connected to the adjacent first dust outlet 4001; a second dust outlet 5002 is opened on the lower rear side of the leveler 5; based on a top-down view, the front and rear sides of the leveler 5 gradually converge towards the center, making the front and rear sides of the leveler 5 flared, using the flared sides to improve the dust collection. The dust collection and discharge system effectively prevents dust from clogging the leveler 5, ensuring the dust reduction effect of the device. Several separation plates 6 are installed inside the leveler 5. A crushing system is installed inside the dust cover 2. During the semi-coke conveying process, the dust is collected by the dust guide plate 4 to prevent dust from spreading inside the dust cover 2 and becoming difficult to handle. Water mist nozzles 3 are used to humidify and settle the dust, while the settled dust falls onto the dust guide plate 4. Through the cooperation of the dust guide plate 4 and the leveler 5, the leveler 5 evenly spreads the humidified dust on the surface of the semi-coke. Thus, during the conveying process, the humidified dust suppresses the dust from the semi-coke, reduces the phenomenon of dust diffusion, and ensures the air quality during the workshop operation.

[0020] It also includes a conveying assembly, which includes a drive unit 101, a servo motor 102, and a conveyor belt 103; five drive units 101 are fixedly connected to the lower left side of the dust cover 2, and the drive units 101 are electric push rods; another five drive units 101 are fixedly connected to the lower right side of the dust cover 2; the telescopic end of each drive unit 101 is fixedly connected to the conveyor belt 103; the semi-coke is transported through the conveyor belt 103, and the discharge port on the lower side of the crusher 1 is located above the conveyor belt 103; a servo motor 102 is fixedly connected to the rear right side of the conveyor belt 103.

[0021] Based on a front-to-back view, two adjacent water mist nozzles 3 are tilted to the left and right sides respectively. The tilted water mist nozzles 3 improve the dust falling into the dust guide plate 4 during the dust humidification and settling process, prevent the dust from settling irregularly on the conveyor belt 103, reduce the dust settling effect on the rear end of the conveyor belt 103, reduce the air quality in the workshop, and ensure human health.

[0022] Based on a front-to-back view, the two dust guide plates 4 are arranged in a figure-eight shape. As the dust diffuses upward, the two dust guide plates 4 are tilted and gradually gather the dust below the water mist nozzle 3, improving the dust reduction capability of the water mist nozzle 3, preventing the dust from being insufficiently humidified and thus spreading into the workshop, reducing visibility in the workshop, and reducing the risk of manual operation.

[0023] Taking the middle rear side of the leveler 5 as a reference, the rear of several separation plates 6 located on the left side of the leveler 5 bends towards the left side of the leveler 5, and the rear of several separation plates 6 located on the right side of the leveler 5 bends towards the right side of the leveler 5. The separation plates 6 improve the effect of the leveler 5 in separating and spreading dust, so that the humidified dust is evenly spread on the surface of the semi-coke. This prevents the humidified dust from not being evenly spread on the surface of the semi-coke, which would cause dust to be generated during the transportation of semi-coke, reduce the air quality in the workshop, and harm human health.

[0024] The specific measures for dust control during the transportation of semi-coke are as follows: Large pieces of semi-coke are crushed by crusher 1, and the crushed semi-coke is discharged through the discharge port on the lower side of crusher 1, allowing it to fall into the rear end of conveyor belt 103. Servo motor 102 drives conveyor belt 103 to rotate counterclockwise, based on a right-to-left perspective, thus transporting the crushed semi-coke to the front end of conveyor belt 103. When the semi-coke reaches the front end of conveyor belt 103, to prevent excessive dust from being stirred up during the fall due to the high distance between the semi-coke and the ground, the tilt angle of conveyor belt 103 is adjusted by drive component 101, thereby adjusting the height of the front end of conveyor belt 103 from the ground, shortening the distance the semi-coke falls onto the conveyor belt surface, and reducing dust generation. Because the small dust particles in the semi-coke are transported... During the process, dust may rise and cause dust pollution in the workshop, seriously endangering human health. To prevent this, a dust cover 2 is used to isolate the area above the conveyor belt 103, preventing the dust from spreading back into the workshop. To further enhance the dust suppression effect, as the dust passes through the dust cover 2, the upward-sloping structure of two dust guide plates 4 collects the dust as it spreads upwards, preventing it from spreading in all directions. At this time, the upper side of the two dust guide plates 4 gradually gathers the dust below the water mist nozzles 3, which humidify the dust and cause it to settle downwards. This improves the dust suppression capability of the water mist nozzles 3, preventing the dust from being insufficiently humidified and spreading into the workshop, thus reducing visibility and improving the safety of personnel. To mitigate operational risks and enhance dust settling on the dust guide plates 4, the water mist nozzles 3 are tilted to guide the dust to the left and right sides of the dust cover 2 during the humidification and settling process. This directs the dust towards the opposite sides of the two dust guide plates 4, ensuring more precise dust settling onto them. This prevents uneven settling of the humidified dust on the conveyor belt 103, which would reduce the dust settling effect at the rear of the conveyor belt 103, lowering workshop air quality and harming human health. As the humidified dust settles on the dust guide plates 4, the conveyor belt 103 tilts upwards during the stacking process, causing the dust guide plates 4 to gradually tilt downwards from front to back. This further guides the dust on the dust guide plates 4 to the rear of the dust guide plates 4. Upon reaching the rear of the dust guide plate 4, the dust is conveyed into the leveler 5 through the first dust outlet 4001 and through hole 5001. To improve the leveling effect of the leveler 5, the separation plate 6 is arranged in a V-shape at its rear end. After entering the leveler 5, the dust is guided to the left and right sides by the separation plate 6, resulting in a uniform dust distribution. This improves the dust reduction effect of the leveler 5 during the transportation of semi-coke. After the humidified dust is evenly distributed by the separation plate 6, dust is generated as the semi-coke falls onto the conveyor belt 103 because the discharge port on the lower side of the crusher 1 is located above the conveyor belt 103. To suppress dust generation at the rear end of the conveyor belt 103, the humidified dust is conveyed to the rear end of the conveyor belt 103 through the second dust outlet 5002.This process ensures that dust is evenly distributed on the surface of the crushed semi-coke. The humidified dust suppresses dust on the surface of the semi-coke, thereby suppressing dust emissions at the rear end of conveyor belt 103. This dust reduction during semi-coke transport ensures air quality in the workshop and protects worker health.

[0025] Example 2 Based on Example 1, such as Figures 6-8 As shown, the crushing system includes an industrial fan 201, a separation membrane 202, and a guide block 203. The industrial fan 201 is fixedly connected to the front inner side of the dust cover 2. At least four separation membranes 202 are movably connected to the rear upper side of each dust guide plate 4, and the separation membranes 202 are made of rubber. A guide block 203 is fixedly connected to the rear side of each dust guide plate 4. Because dust tends to stick after humidification, it adheres to the dust guide plates 4. To prevent this, the industrial fan 201 rotates, blowing the separation membranes 202, causing them to swing back and forth on the upper surface of the dust guide plates 4. The swinging action of the separation membranes 202 scrapes and disperses the clumps of dust, preventing dust from agglomerating and sticking. The upper surface of the dust guide plate 4 prevents air circulation and thus prevents dust treatment. At this time, the broken dust is guided to the first dust outlet 4001 by the guide block 203 to prevent the dust from spreading out of the dust cover 2. At the same time, when the industrial fan 201 drives the separation membrane 202 to swing, the pressure on the front side of the industrial fan 201 draws the dust raised at the front end of the conveyor belt 103 into the dust cover 2, thereby breaking up the dust and collecting the dust at the front end of the conveyor belt 103. This prevents the generation of a large amount of dust during the material stacking process at the front end of the conveyor belt 103, reduces the air quality in the workshop, ensures the air quality in the workshop, reduces the impact of dust on human health, and prevents the dust from exploding.

[0026] With a top-down view as a reference, adjacent separation membranes 202 are staggered. While the separation membranes 202 are deformed under force to guide and break up the dust, the staggered separation membranes 202 are used to scrape and disperse the agglomerated dust multiple times, preventing dust from clogging the first dust outlet 4001, improving the dust breaking effect, and ensuring the normal operation of the device.

[0027] With a reference view from right to front, the front side of the guide block 203 is set to tilt to the right. In order to improve the dust guiding effect of the industrial fan 201, the guide block 203 and the industrial fan 201 work together. The tilted structure of the guide block 203 further guides the broken dust to the first dust outlet 4001. At the same time, the tilted structure of the guide block 203 guides the air blown out by the industrial fan 201 to the first dust outlet 4001, so that the dust on the first dust outlet 4001 comes into full contact with the airflow, preventing dust from accumulating on the first dust outlet 4001 and clogging the first dust outlet 4001, thus ensuring the dust reduction effect of the device.

[0028] Example 3 Based on Examples 1 and 2, such as Figure 1 , Figure 9 and Figure 10 As shown, it also includes an air guide 301; the air guide 301 is fixedly connected to the front side of the two dust guide plates 4; as the dust above the conveyor belt 103 is lifted, it is affected by the airflow blown by the industrial fan 201, causing the dust to spread in all directions, thereby reducing the dust collection of the dust guide plates 4. In order to prevent this phenomenon, when the industrial fan 201 is turned on, the air guide 301 guides the airflow generated by the industrial fan 201 to the left and right sides of the dust guide plates 4, and then guides the airflow blown by the industrial fan 201 to flow towards the first dust outlet 4001, so that the air above the conveyor belt 103 can circulate naturally, ensuring that the dust above the conveyor belt 103 is not disturbed by the industrial fan 201. At the same time, by using the airflow to guide the air to the left and right sides of the dust guide plates 4, the dust is carried by the airflow on both sides into the dust cover 2 and falls better on the dust guide plates 4, further improving the dust reduction effect of the device.

[0029] Based on a front-to-back view, the lower front part of the air guide 301 is designed to gradually slope downwards from the middle to the left and right sides. In order to improve the dust extraction effect of the industrial fan 201, the inclined structure of the lower side of the air guide 301 guides the airflow generated by the industrial fan 201 during operation into the dust cover 2, thereby guiding the dust raised at the front end of the conveyor belt 103 into the dust cover 2. This prevents the industrial fan 201 from failing to effectively extract the dust into the dust cover 2, which would cause the dust to spread in the workshop, obstruct the workers' vision, increase the risk of workers' operation, and harm human health.

[0030] Two inverted triangular blocks that gradually extend backward are provided on the rear side of the air guide 301. In order to improve the air guiding effect of the air guide 301, when the air flows backward along the left and right sides of the air guide 301, the two triangular blocks are used to prolong the time of the air on both sides of the air guide 301, thereby improving the air guiding effect of the air guide 301 to the left and right sides of the two dust guide plates 4, and ensuring dust collection and dust suppression.
