Description

Technical Field

[0001] This utility model belongs to the field of metallurgical raw material processing technology, and in particular relates to a special water-adding and dust-prevention device for vehicles carrying dry coke powder from seed material yards. Background Technology

[0002] In the steelmaking process, dry coke powder is a commonly used raw material, usually transported by trucks and stored in the truck bed. Because dry coke powder is prone to dust generation in its dry state and has poor flowability and is not easy to mix, it usually needs to be mixed with water in the stockyard.

[0003] In existing technologies, adding water to dry coke powder in the material yard is usually done manually using a handheld water hose. This method has several problems. First, the water addition process relies on manual operation, making it difficult to maintain a consistent water flow coverage and spray intensity, easily leading to uneven water addition. This results in some coke powder being overly wet while others remain dry, affecting the uniformity of material mixing and subsequent use. Second, manual operation makes it difficult to precisely control the amount of water added, which may result in insufficient water addition, failing to achieve the desired improvement, or excessive water addition, causing coke powder to clump or be lost, increasing resource waste. Third, manual water addition is inefficient and labor-intensive, unsuitable for large-scale, continuous operations, severely restricting the improvement of production efficiency.

[0004] Furthermore, because an effective water mist coating and particulate dust suppression mechanism are not formed during the water addition process, coke powder still easily generates a large amount of smoke and dust during dumping, transportation, and water addition, which not only pollutes the environment but also poses a threat to the health of operators. Currently, multiple mist cannons are usually installed around the vehicle for auxiliary dust suppression, but such equipment has problems such as large footprint, high energy consumption, and limited coverage, and the actual dust suppression effect is not ideal, making it difficult to achieve efficient dust control.

[0005] In summary, existing technologies for adding water to dry coke powder and reducing dust have drawbacks such as uneven water addition, difficulty in control, cumbersome operation, low efficiency, and poor dust control effect. Utility Model Content

[0006] In view of the problems of uneven water addition, difficulty in controlling the amount of water added, low operating efficiency, and poor dust control effect in the existing technology of adding water to dry coke powder, this utility model provides a special water addition and dust prevention device for dry coke powder vehicles in material yards.

[0007] This utility model is implemented as follows: a water-filling and dust-prevention device for dry coke powder vehicles in a material yard, characterized by: a water-filling and dust-prevention unit, the water-filling and dust-prevention unit being a rectangular structure distributed on all four sides above the vehicle; the water-filling and dust-prevention unit including a straight water trough and a water-filling pipe assembly; the straight water trough being horizontally arranged; the water-filling pipe assembly including a water-filling pipe and a water-filling pump, the water-filling pipe being fixedly installed on the straight water trough and extending horizontally in a straight line, the water-filling pipe having downward-facing water-filling outlet holes evenly distributed along its length; and the water-filling pump connecting the water-filling pipe and the straight water trough and conveying water from the straight water trough to the water-filling pipe.

[0008] In the above technical solution, preferably, a dustproof pipe assembly is included, with N dustproof pipe assemblies installed on the outer side of the straight water tank. The dustproof pipe assembly includes a dustproof water supply pipe, a dustproof water pump, and a water guide pipe. The dustproof water supply pipe is installed on the straight water tank and extends vertically downward. The dustproof water supply pipe is provided with dustproof water outlet nozzles spaced apart along its length. The water guide pipe connects the dustproof water supply pipe and the straight water tank. The dustproof water pump connects the water guide pipe and the dustproof water supply pipe and transports water from the straight water tank to the dustproof water supply pipe through the water guide pipe.

[0009] In the above technical solution, preferably, a horizontal linear guide rail is installed on the outer wall of the linear water tank, a sliding component that moves along the horizontal linear guide rail is installed on the horizontal linear guide rail, and the dustproof water supply pipe is installed on the sliding component.

[0010] In the above technical solution, preferably, the horizontal linear guide is a C-shaped linear guide, and the sliding component is a roller fitted in the horizontal linear guide.

[0011] In the above technical solution, preferably, the water guide pipe is a flexible pipe, and a counterweight is installed on the part of the water guide pipe near its lower inlet.

[0012] In the above technical solution, preferably, the inlet of the water guide pipe is equipped with a filter screen.

[0013] In the above technical solution, preferably, the water supply pipe is fixedly installed on the lower wall of the straight water tank and has N horizontally extending inward water supply branches that are connected to the water supply pipe. The water supply branches have downward-facing water outlet holes that are evenly spaced along the length direction.

[0014] In the above technical solution, preferably, it includes a hanging bracket and a suspension bracket. The lower end of the suspension bracket is connected to the straight water tank, and the upper end of the suspension bracket is connected to the hanging bracket through a lifting guide rail. The lifting guide rail is horizontally set and perpendicular to the straight water tank.

[0015] The water-adding and dust-prevention device for dry coke powder vehicles proposed in this utility model has a reasonable structural design and many significant advantages.

[0016] First, by setting up water-adding and dust-prevention units distributed on the four sides of a rectangle, the device can achieve full-coverage water addition to the coke powder in the vehicle bed, significantly improving the uniformity of water addition, thereby ensuring a more stable and consistent mixing effect of the coke powder, which is conducive to improving the performance of raw materials and the efficiency of subsequent processes.

[0017] Secondly, the water supply pipe in the device is arranged along a horizontal straight water tank and is equipped with evenly distributed downward-facing water outlets. Combined with the water pump, the water output is precisely controlled, making the water supply process more controllable. This fundamentally avoids problems such as material clumping, loss, or dust suppression caused by excessive or insufficient water supply, achieving efficient use of water resources and having a good water-saving effect.

[0018] This device also significantly optimizes ease of operation and automation, reducing manual intervention, lowering labor intensity, and improving operational efficiency, making it particularly suitable for high-frequency, high-volume industrial operations. In terms of environmental protection, by directionally spraying water mist onto the surface of coke powder, it effectively suppresses dust dispersion during water addition and material handling, reducing pollution to the working environment, lowering health risks to workers, and overall improving operational safety and environmental quality at the material yard. Data shows that it can save approximately 3,400 yuan in water addition costs per month, further enhancing the device's comprehensive application value.

[0019] In summary, this water-adding dust suppression device has significant advantages in improving the uniformity of water addition to coke powder, increasing operational efficiency, accurately controlling the amount of water added, effectively suppressing dust pollution, saving water resources, and protecting the health of operators, demonstrating good industrial adaptability and promising prospects for promotion.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0025] To address the problems of uneven water addition, difficulty in controlling the amount of water added, low operating efficiency, and poor dust control in the current technology for adding water to dry coke powder, this utility model provides a special water addition and dust prevention device for vehicles handling dry coke powder in material yards. To further illustrate the structure of this utility model, a detailed description is provided below in conjunction with the accompanying drawings:

[0026] A water-filling and dust-prevention device for vehicles carrying dry coke powder from a material yard includes water-filling and dust-prevention units arranged in a rectangular shape above the vehicle. Figure 1 In this embodiment, the main core component of the water-filling and dust-proofing unit is a straight water trough 1, which is horizontally positioned. Above the straight water trough is a hanging frame 2 fixed to the roof of the factory building, which suspends the straight water trough via a hanger 3. Specifically, the lower end of the hanger is connected to the straight water trough, and the upper end is connected to the hanging frame via a lifting guide rail, which is horizontally positioned and perpendicular to the straight water trough. The hanging frame is made of I-beams, with grooves on both sides forming the lifting guide rail. Rollers 4 are installed at the upper end of the hanger, fitting into the grooves on both sides of the I-beam. This allows the water-filling and dust-proofing unit to move in a direction perpendicular to its length, thereby changing the area of ​​the rectangular area within the surrounding structure. This area is adapted to the size of the vehicle bed and needs to surround the perimeter. For convenient automatic adjustment, an adjustment motor driving the rollers can be installed at the upper end of the hanger. The transmission connection between the adjustment motor and the rollers is a known technique in the mechanical field. The straight water trough can be equipped with an independent main water pipe supplying water to its interior, ensuring sufficient water inside.

[0027] Please see Figures 2-4 The water supply and dust suppression unit includes a water supply pipe assembly. This assembly includes a water supply pipe 5, a water pump 6, and water supply branch pipes 7. The water supply pipe is fixedly installed on a straight water trough and extends horizontally in a straight line. The water supply pipe has downward-facing water outlet holes 8 evenly distributed along its length. The water pump connects the water supply pipe and the straight water trough, supplying water from the straight water trough to the water supply pipe. The water supply pipe is fixedly installed on the lower wall of the straight water trough and has N horizontally extending inward water supply branch pipes connected to it. Each branch pipe has downward-facing water outlet holes evenly spaced along its length. The water supply pipe and water supply branch pipes form a structure that supplies water to the inner area of ​​the water supply and dust suppression unit. The water pump, acting as a hydrodynamic supply component, sprays water from the water outlet holes, ensuring uniform water supply to the coke powder in the vehicle's cargo bed. The water supply pipe forms a uniform circumferential water supply from top to bottom, and at the same time, a dust-suppressing water curtain is formed, which has a good dust suppression effect.

[0028] The water-filling dust suppression unit also includes dust suppression pipe assemblies, with N dust suppression pipe assemblies installed on the outer side of the straight water channel. The function of the dust suppression pipe assemblies is to form a vertically arranged, horizontally sprayed water mist barrier around the vehicle to prevent dust from spreading outwards.

[0029] The dustproof pipe assembly includes a dustproof water supply pipe 9, a dustproof water pump 10, and a water guide pipe 11. The dustproof water supply pipe is installed in a straight water trough and extends vertically downwards. It is equipped with dustproof water nozzles spaced along its length. The water guide pipe connects the dustproof water supply pipe and the straight water trough; one end of the water guide pipe connects to the upper end of the dustproof water supply pipe, and the other end enters the straight water trough. The dustproof water pump connects the water guide pipe and the dustproof water supply pipe, and delivers water from the straight water trough to the dustproof water supply pipe through the water guide pipe. The housing of the dustproof water pump is fixed to the upper end of the dustproof water supply pipe.

[0030] To allow the position of the dustproof pipe assembly and the width between two adjacent dustproof pipe assemblies to be adjusted according to vehicle size or specific workspace, in this embodiment, the dustproof pipe assembly is designed as a sliding adjustable type. Specifically, a horizontal linear guide rail is installed on the outer wall of the linear water trough, and a sliding component that moves along the horizontal linear guide rail is installed on the horizontal linear guide rail. The dustproof water supply pipe is installed on the sliding component. Specifically, the horizontal linear guide rail is a C-shaped linear guide rail 12, and the sliding component is a roller 13 fitted within the horizontal linear guide rail. A clamp sleeve is fixed near the upper end of the dustproof water supply pipe, and an axle is fixed inside the clamp sleeve. The roller is mounted on the axle via a bearing. The water supply pipe is a flexible pipe, and a counterweight 14 is installed near its lower inlet. A filter screen is provided at the inlet of the water supply pipe. The roller and C-shaped linear guide rail are chosen as the components for enabling the dustproof pipe assembly to slide because the combination of rollers and C-shaped linear guide rails requires low installation precision, is less affected by dust in the working environment, and operates reliably and stably. On the other hand, when adjusting the position of the dustproof water supply pipe, the pipe will deflect and swing, which is more conducive to pulling the rollers. Furthermore, the dustproof water supply pipe mainly bears axial tensile force and rarely bears torque, preventing it from bending due to long-term use and avoiding jamming. During the adjustment of the dustproof pipe assembly, its upper end will swing. The selection of flexible pipes and the design of the counterweight ensure that the water inlet of the water supply pipe is always below the water surface, preventing water flow interruption.

[0031] The switch used to control the opening and closing of the dustproof water pump in the dustproof pipe assembly can be fixed at the lower end of the dustproof water supply pipe.

[0032] 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.
