Description

Technical Field

[0001] This utility model relates to the field of dust suppression device technology, and more specifically, to a dust suppression device for a coal storage shed. Background Technology

[0002] Coal storage sheds, as the main storage areas for coal and coke in various industrial enterprises, are generally enclosed spaces constructed with steel structures to store materials such as coal and coke. In actual production, coal and coke are transported to the sheds via conveyor belts or vehicles and then removed by vehicles when needed. This transfer process generates a large amount of dust, severely affecting visibility inside the sheds and posing significant safety hazards. To address the dust problem inside the sheds, dust suppression devices are typically used to reduce dust dispersion.

[0003] However, the existing dust suppression devices for coal storage sheds have the following problems when in use: The coal storage shed is an enclosed space with virtually no strong convective airflow. The only source of strong convection is vehicle exhaust vents. Other major dust-generating points are due to dust produced when materials fall freely from a height difference. To address the strong convective airflow from vehicle exhaust vents, the exhaust vents are redesigned to prevent contact between the exhaust and the dust particles, thus avoiding direct impact and dust generation. For dust generated from the free fall of materials, dust suppression devices are used. Traditional dust suppression methods typically involve mist cannons or full-shed spraying. However, both of these methods suffer from problems such as easy dust dispersion, poor dust suppression effectiveness, and high difficulty in dust control, resulting in insufficient practical application and difficulty in guaranteeing effective dust suppression within the coal storage shed.

[0004] This invention can control dust throughout the entire coal transportation process in a coal storage shed. By using multiple structures to buffer coal and suppress dust diffusion, combined with atomized dust suppression and water resource recovery, it can effectively improve the working environment, reduce coal loss, and has both dust suppression and energy-saving and environmental protection functions.

[0014] 1. By setting up inclined plate one, buffer chamber, inclined plate two, and drop box, the combination of inclined plate one, buffer chamber, inclined plate two, and drop box can achieve buffering and dust reduction throughout the entire process from coal entry to discharge. The buffer chamber is inverted cone-shaped, which can reduce the impact of falling coal and reduce initial dust. The staggered inclined plate one can disperse the coal flow and reduce the collision intensity between coals. The inclined design of inclined plate two and drop box guides the coal to slide slowly and avoids the dust diffusion caused by rapid falling. The overall structure weakens the power of dust generation from the source. Through multi-stage buffering, the impact and friction of coal are reduced. In conjunction with other dust reduction components, it can effectively suppress the large-scale diffusion of dust, improve the working environment quality of coal storage shed, and reduce the loss during coal transportation. 2. By incorporating a guide pipe and a rotating rod, the inclined guide pipe, in conjunction with the spiral blades on the rotating rod, smoothly pushes the coal, avoiding severe collisions and friction caused by scattering and accumulation during transport. The rotating rod drives the spiral blades to move the coal along a fixed path, reducing impact with the pipe wall. Simultaneously, the guide pipe forms a relatively enclosed space, suppressing dust leakage. This combination ensures transport efficiency, reduces dust sources at the transport stage, and, in conjunction with other dust suppression structures, improves overall dust suppression effectiveness while reducing coal transport losses. 3. Equipped with atomizing nozzles, a water outlet pipe, and a receiving box, the atomizing nozzles spray water mist into the feed pipe, which can adsorb dust generated during coal transportation and inhibit dust diffusion at the source; the water outlet pipe drains excess water from the feed pipe to prevent water accumulation from affecting transportation; and the receiving box collects this water for subsequent treatment or reuse. The three components work together to improve purification through wet dust suppression and achieve water resource recovery, conforming to energy conservation and environmental protection principles, and working in conjunction with other structures to ensure a safe working environment in the coal storage shed. 4. In summary, this type of dust suppression device for coal storage sheds, through its structure including a feeding tank, a guide pipe, atomizing nozzles, a discharge box, and a receiving box, achieves initial buffering of coal with the help of a buffer chamber and inclined plates, reducing dust generated by falling impacts; the guide pipe, in conjunction with a rotating rod and spiral blades, smoothly transports coal within a closed space, reducing dust diffusion caused by collisions and friction; the atomizing nozzles precisely adsorb dust generated during transportation through water mist, enhancing the dust suppression effect; the discharge box, with its inclined plate and tilted design, guides coal to slowly discharge, further reducing the driving force for dust generation; and the receiving box recovers excess water, achieving water resource recycling. These structures work together to comprehensively improve the dust suppression efficiency of coal storage sheds, optimize the working environment, and reduce coal loss, thus combining practicality with energy conservation and environmental protection.

[0019] The following will refer to the appendix in the embodiments of this utility model. Figures 1-3 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0020] Please see Figure 1-3In this embodiment of the utility model, a dust suppression device for a coal storage shed includes: a fixed frame 1, a guide pipe 2 disposed inside the fixed frame 1, a dropping box 3 disposed below the other end of the guide pipe 2, a receiving box 4 fixedly installed at the bottom of the fixed frame 1, a feeding tank 101 fixedly installed at the upper end of the fixed frame 1, the bottom of the feeding tank 101 being fixedly connected to the guide pipe 2, the guide pipe 2 being inclined from left to right, and a rotating rod 203 being rotatably installed inside, with a spiral blade fixedly installed on the surface of the rotating rod 203, inclined plates 105 being staggered from top to bottom inside the feeding tank 101, and inclined plates 301 being fixedly installed inside the dropping box 3, with one side of the dropping box 3 tilting downwards to the left. The feed tank 101 is inclined and has an inlet 102 at its upper end. Inside the feed tank 101 is a buffer chamber 103, which is inverted conical in shape and has a discharge port 104 at its bottom. The discharge port 104 is fixedly connected to the upper left side of the guide pipe 2. Transmission pipes 206 are fixedly installed on both the upper left side and lower right side of the guide pipe 2. The upper transmission pipe 206 is fixedly connected to the discharge port 104, and the lower transmission pipe 206 is fixedly connected to the discharge box 3. The discharge box 3 has a discharge port 302 at its bottom. Coal first enters the device through the inlet 102 at the upper end of the feed tank 101. Inside the feed tank 101, inclined plates 1-1 are fixedly installed in a staggered pattern. The 05 setting guides the coal to slide slowly left and right within the feed tank 101, further reducing collisions and impacts during coal flow and minimizing dust generation. The coal then enters the buffer chamber 103 within the feed tank. Due to the inverted conical design of the buffer chamber 103, the coal is further buffered and decelerated here, reducing dust generated during its descent. After passing through the buffer chamber 103, the coal is discharged from the bottom discharge port 104 and enters the guide pipe 2 through the transmission pipe 206 on the upper left side of the guide pipe 2. At this time, the rotating rod 203 inside the guide pipe 2 and the fixed spiral blades on its surface begin to work. Using the rotational thrust of the spiral blades, the coal is propelled along... The guide pipe 2, which is inclined from left to right, transports coal from left to right. During the transport process of the guide pipe 2, the coal is smoothly conveyed to the transmission pipe 206 on the lower right side and enters the drop box 3 through the transmission pipe. The inclined plate 301 fixedly installed inside the drop box 3 and the setting of one side inclined to the lower left can guide the coal to slide slowly in the drop box, further reducing the collision and impact during the coal flow process and reducing dust generation. Finally, the coal is discharged from the discharge port 302 at the bottom of the drop box 3, completing the entire conveying process. Throughout the process, the dust source points from the coal entry to the discharge are controlled, which can effectively avoid the large-scale spread of dust.

[0021] In this embodiment of the invention, partitions 201 are fixedly installed on both the left and right sides inside the feed pipe 2. A motor 202 is fixedly installed on the right end of the right partition 201, and the output end of the motor 202 is fixedly connected to the rotating rod 203. The rotating rod 203 is rotatably installed between the two partitions 201. The partitions 201 fixedly installed on both the left and right sides inside the feed pipe 2 provide a stable installation support structure for the rotating rod 203, allowing the rotating rod 203 to rotate smoothly between the two partitions 201. At the same time, they divide the internal space of the feed pipe 2 to a certain extent. Together with the spiral blades on the surface of the rotating rod 203, they more effectively transport the coal entering the feed pipe 2, ensuring that the coal follows the inclination of the feed pipe 2. The smooth directional movement reduces the scattering and impact of coal within the feed pipe 2, further lowering the likelihood of dust generation and facilitating the better implementation of dust control measures that address dust at its source. A motor 202, fixedly installed at the right end of the right-side partition 201, serves as the power source. Its output end is fixedly connected to the rotating rod 203, driving the rod 203 to rotate, which in turn drives the spiral blades, providing power for the coal conveying process within the feed pipe 2 and ensuring the smooth operation of the entire conveying process. Driven by the motor 202, the rotating rod 203 rotates, and the spiral blades on its surface rotate accordingly, pushing and conveying the coal. It is the direct power transmission component for the movement of coal within the feed pipe 2.

[0022] In this embodiment of the invention, several atomizing nozzles 204 are fixedly installed at equal intervals on the upper end of the feed pipe 2, and a water outlet pipe 205 is fixedly installed on the left end of the feed pipe 2. A water passage hole is opened downward from the middle of the left side partition 201. The water outlet pipe 205 is fixedly connected to the receiving box 4. The main function of the several atomizing nozzles 204 fixedly installed at equal intervals on the upper end of the feed pipe 2 is to spray atomized water into the feed pipe 2, using the water mist to capture and adsorb dust generated during coal transportation, thus suppressing dust diffusion at the source. The equidistant distribution design ensures a more uniform water mist coverage and improves the dust suppression effect. The water outlet pipe 205 fixedly installed on the left end of the feed pipe 2 serves as a drainage channel for water accumulated inside the feed pipe 2, draining any unused water from the feed pipe 2. The completely evaporated water mist condenses or excess atomized water is discharged and fixedly connected to the receiving box 4, so that the discharged water eventually flows into the receiving box 4, realizing the collection and recycling of water resources and avoiding the random discharge of sewage. The water passage hole opened downward from the middle of the left side partition 201 provides a flow path for the water accumulated inside the guide pipe 2, so that the water in the guide pipe 2 can flow to the left through the water passage hole and finally be discharged into the receiving box 4 through the water outlet pipe 205. The opening position is in the middle downward, which ensures smooth drainage and avoids affecting the normal transportation path of coal. These components together constitute the wet dust suppression and water circulation system in the guide pipe. In conjunction with the previous transportation structure, the dust suppression effect is further enhanced while realizing the stable transportation of coal.

[0023] In this embodiment of the invention, a water inlet 401 is provided at the upper end of the receiving box 4, and the water inlet 401 is fixedly connected to the water outlet pipe 205. A collection box 402 is slidably connected inside the receiving box 4, and the receiving cavity inside the collection box 402 is located below the water inlet 401. A handle 403 is fixedly installed on the outer end face of the collection box 402. The water inlet 401 is located at the upper end of the receiving box 4 and is fixedly connected to the water outlet pipe 205. This design allows water discharged from the water outlet pipe 205 to flow accurately into the receiving box 4 through the water inlet 401, providing a clear channel for water resource collection and ensuring smooth and targeted drainage. The collection box 402 is slidably connected inside the receiving box 4, and its internal receiving cavity is located below the water inlet 401, capable of receiving the water flowing from the water inlet 401. The water entering the container allows for centralized collection of water discharged from the feed pipe 2. The sliding connection facilitates the removal and insertion of the collection box 402, making it convenient for subsequent treatment or reuse of the collected water. The handle 403 is fixedly installed on the outer end face of the collection box 402, providing a convenient point of leverage for operators to operate the collection box 402. When it is necessary to clean the water in the collection box 402 or to perform maintenance, the collection box 402 can be easily pulled out of the receiving box 4 by holding the handle 403. The operation is simple and labor-saving, improving the convenience of device maintenance. These components work together to not only realize the recycling of water resources, which is in line with the concept of energy conservation and environmental protection, but also reduce the difficulty of device maintenance through convenient structural design, further improving the overall function of the coal storage shed dust suppression device.
