Description

Technical Field

[0001] This utility model relates to the field of unloading technology, and in particular to an unloading dust prevention system. Background Technology

[0002] During the unloading process of mine cars, the impact force generated when materials fall from the discharge port produces a large amount of dust, especially fine particles with a diameter of less than 5 micrometers. This dust not only pollutes the working environment but may also harm the health of operators and affect the surrounding ecological environment.

[0003] In existing technologies, dust suppression using spraying is commonly employed to control dust from mining cars, with the spraying area typically positioned around the car's perimeter. However, during unloading, dust gradually spreads with the airflow to the surrounding area, increasing the dust dispersion range. This not only reduces the dust suppression effect but also increases material waste. Furthermore, improper spraying area placement makes it difficult to precisely cover the dust dispersion path, resulting in low dust suppression efficiency and an inability to effectively control the spread of fine dust, thus negatively impacting the working environment and the surrounding ecosystem.

[0004] Therefore, there is an urgent need for a dust suppression technology at the discharge port that can effectively suppress the diffusion of fine dust without affecting the operation of downstream equipment, in order to overcome the shortcomings of existing technologies. Utility Model Content

[0005] The main purpose of this invention is to provide a dust prevention system for unloading materials, which aims to reduce the spread of dust during the unloading process, improve the dust suppression effect, and reduce material loss.

[0006] To achieve the above objectives, this utility model proposes a material unloading and dust prevention system, comprising:

[0007] Rainproof frame, which has a stopping area and an unloading area;

[0008] A hopper, sunken and positioned at the bottom of the rainproof frame, is used to receive materials; and

[0009] A spray assembly, which is located inside the rainproof frame and is capable of spraying towards the hopper;

[0010] The unloading area is located between the spray assembly and the silo. When the unloading vehicle dumps the material into the silo in the stopping area, the dust that rises to the unloading area is sprayed by the spray assembly and falls into the silo.

[0011] Furthermore, when the unloading vehicle is unloading in the stopping area, the spray end of the spray assembly is positioned above the unloading port of the unloading vehicle.

[0012] Furthermore, the spraying end of the spraying assembly can move closer to or further away from the hopper along the height direction of the rainproof frame.

[0013] Furthermore, the interior of the rainproof frame is also connected to a shielding area, which is located above the stopping area. When the unloading vehicle is in the stopping area, the shielding area is located above the front of the unloading vehicle to block dust from the unloading area.

[0014] Furthermore, in the horizontal direction, the spraying end of the spraying assembly at least covers the discharge end of the hopper near the unloading area.

[0015] Furthermore, the spray assembly includes a plurality of nozzles uniformly connected within the rainproof frame, the nozzles being used to spray liquid or mist droplets.

[0016] Furthermore, some of the nozzles are distributed in a C-shape, square shape, or frame shape in the horizontal direction.

[0017] Furthermore, the spray assembly includes a pump station and a water storage device connected in sequence to the water supply end of the spray head. The water storage device is used to store liquid and to flow the liquid into the pump station. The pump station is used to pressurize the liquid from the water storage device and to supply the pressurized liquid into the spray head.

[0018] Furthermore, the pump station includes a connector and at least one pump body connected between the connector and the water storage unit, the pump body drawing liquid from the water storage unit and flowing the liquid from the connector to the nozzle.

[0019] Furthermore, an ultrasonic system is connected between the pump station and the nozzle.

[0020] The above technical solution has the following advantages:

[0021] This invention features a sunken hopper positioned at the bottom of a rainproof frame, with a discharge area above the hopper. This allows the unloading vehicle to drop materials from the discharge area into the hopper. The material in the hopper generates dust, which gradually moves to the discharge area. A spray system above the discharge area restricts dust overflow and sprays liquid towards the discharge area. The liquid combines with the dust and falls into the hopper, thus suppressing dust overflow at its source in the discharge area, reducing the spread of dust during the unloading process, improving dust suppression, and minimizing material loss.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain this utility model and do not constitute a limitation on this utility model.

[0029] like Figure 1 and Figure 3 As shown, a material unloading dust prevention system includes a rainproof frame 1, a hopper 5, and a spray assembly 3. The rainproof frame 1 has a dwelling area 12 and an unloading area 4. The hopper 5 is sunken and placed at the bottom of the rainproof frame 1 to receive materials. The spray assembly 3 is placed inside the rainproof frame 1 and can spray towards the hopper 5. The unloading area 4 is located between the spray assembly 3 and the hopper 5. When the unloading vehicle 6 dumps materials into the hopper 5 in the dwelling area 12, the dust from the materials that rise to the unloading area 4 is sprayed by the spray assembly 3 and falls into the hopper 5. The rainproof frame 1 can be made of a rainproof canopy, such as cloth or plastic, and its sides are supported by steel plates 2. The entrance and exit of the rainproof frame 1 are equipped with stacking doors 13, which can be closed or opened in time to form a sealed space. The sunken hopper 5 is located below the bottom surface of the rainproof frame 1. When the unloading vehicle 6 moves to the stopping area 12, the unloading vehicle 6 can tilt the material into the hopper 5 to prevent the material from spilling out. The above-mentioned sunken design can also be a semi-sunken design, that is, the top of the hopper 5 is higher than the bottom surface of the rainproof frame 1, so that the top opening of the hopper 5 is closer to the unloading vehicle 6, which can further block the space for material spillage.

[0030] As one embodiment of this application, the spray assembly 3 is used to spray liquid toward the silo 5. It is mounted above the silo 5 of the rainproof frame 1. The unloading area 4 is used to release materials, so that the materials fall into the silo 5 in the unloading area 4. As the materials accumulate and collide in the silo 5, the dust gradually rises to the unloading area 4. The spray assembly 3 sprays liquid onto the unloading area 4, so that the liquid and the dust in the unloading area 4 are fully mixed before falling into the silo 5. This can prevent the dust from spreading outside the unloading area 4, so as not to increase the spread range of the dust and affect the dust suppression effect, and at the same time save the material diffusion loss.

[0031] As one embodiment of this application, such as Figure 1 As shown, when the unloading vehicle 6 is unloading in the stopping area 12, the spray end of the spray assembly 3 is above the unloading port of the unloading vehicle 6. When the unloading vehicle 6 is in the unloading state, its unloading port will gradually turn to the hopper 5. At this time, the spray end of the spray assembly 3 sprays liquid onto the unloading port of the unloading vehicle 6, further curbing the spread of dust at the source and improving the overall dust suppression effect. In addition, the spray end of the spray assembly 3 can spray liquid in the vertical direction at the same time, so that the liquid can fully suppress the dust around the material of the unloading vehicle 6.

[0032] like Figure 1 and Figure 2 As shown, in one embodiment of this application, the spray end of the spray assembly 3 can move closer to or further away from the hopper 5 along the height direction of the rainproof frame 1. The spray end of the spray assembly 3 is installed on the inner wall of the rainproof frame 1 by a bracket, and its height is adjusted by a screw, lead screw or telescopic cylinder to meet the different unloading vehicle 6 heights and improve the versatility of unloading.

[0033] As one embodiment of this application, such as Figure 1 and Figure 3 As shown, the rainproof frame 1 also has a shielding area 11 connected inside. The shielding area 11 is located above the stopping area 12. When the unloading vehicle 6 is in the stopping area 12, the shielding area 11 is located above the front of the unloading vehicle 6 to block dust from the unloading area 4. The shielding area 11 can be separated by cloth or plastic baffles to ensure that the unloading vehicle 6 can enter the stopping area 12. At the same time, the combination of the front of the unloading vehicle 6 and the shielding area 11 can jointly shield the space facing outward from the stopping area 12, reducing the possibility of dust moving out from above the front of the vehicle. When the unloading hopper of the unloading vehicle 6 tilts, the material falling from the unloading area 4 falls into the hopper 5.

[0034] like Figure 1 and Figure 2As shown, in order to improve the dust suppression effect, in the horizontal direction, the spray end of the spray assembly 3 covers at least the unloading end of the hopper 5 near the unloading area 4. When the unloading port of the unloading vehicle 6 is located in the unloading area 4, the spray end completely covers the unloading port of the hopper 5 to perform dust suppression treatment on the unloading port. In addition, the spray end is also set at an angle, that is, the direction of liquid spraying at the spray end can be perpendicular to the hopper 5 or inclined to the hopper 5 to improve the dust suppression capability of the unloading area 4.

[0035] Specifically, the spray assembly 3 includes several nozzles 34 evenly connected within the rainproof frame 1. The nozzles 34 are used to spray liquid or mist. To improve the dust suppression effect, this application preferably uses mist. The mist-like liquid fully combines with the dust in the unloading area 4, and after encapsulating the dust particles, they fall into the hopper 5, which reduces the moisture content in the hopper 5 and also improves the dust suppression capability.

[0036] Several nozzles 34 are arranged in a C-shape, square shape, or frame shape in the horizontal direction. When the nozzles 34 are arranged in a C-shape in the horizontal direction, the opening of the C-shape faces away from the residence area 12. The nozzles 34 are evenly distributed above the hopper 5, and the spray direction of the droplets can be tilted towards the center of the hopper 5 to improve the dust suppression effect. When the nozzles 34 are arranged in a square shape in the horizontal direction, the nozzles 34 are arranged in an array on the support, and the spray direction of the droplets is towards the hopper 5 to reduce the dead corners of dust overflow. When the nozzles 34 are arranged in a frame shape in the horizontal direction, such as a quadrilateral frame, the nozzles 34 are evenly arranged along the periphery of the hopper 5 and spray droplets towards the center of the hopper 5, so that the droplets combine with the dust in the unloading area 4 and settle together in the hopper 5.

[0037] like Figure 1 and Figure 4 As shown, the spray assembly 3 includes a pump station 32 and a water storage unit 31 connected sequentially to the water supply end of the nozzle 34. The water storage unit 31 stores liquid and flows the liquid into the pump station 32. The pump station 32 pressurizes the liquid from the water storage unit 31 and supplies the pressurized liquid into the nozzle 34. The water storage unit 31 can be a water storage tank, water storage pool, etc. The pump station 32 draws the liquid from the water storage unit 31 to the nozzle 34, and the nozzle 34 sprays out a mist of liquid droplets, so that the liquid is fully mixed with the dust in the unloading area 4, thereby achieving the liquid supply to the nozzle 34.

[0038] like Figure 4As shown, the pump station 32 includes a connector 322 and at least one pump body 321 connected between the connector 322 and the water storage unit 31. The pump body 321 draws liquid from the water storage unit 31 and directs the liquid from the connector 322 to the nozzle 34. One pump body 321 may be used, but this application preferably uses two pump bodies 321 connected in parallel to ensure subsequent liquid supply and maintenance operations. The pump body 321 draws the water storage unit 31 towards the connector 322, which guides the liquid to flow to the nozzle 34. A pressure transmitter can be installed on the connector 322 to detect the pressure value of the connector 322, ensuring that the liquid pressure meets the spraying requirements. The connector 322 can also be connected to the water storage unit 31 via a pipeline to prevent damage or blockage of the nozzle 34, which could cause excessive pressure on the connector 322. A drain pipe is also installed on the connector 322 to promptly discharge the wastewater inside, enabling timely unblocking operations.

[0039] An ultrasonic system 33 is also connected between the pump station 32 and the nozzle 34. The cavitation effect generated by ultrasound in the liquid can form tiny bubbles. When these bubbles burst, they generate a powerful impact force, which sprays the unloading area 4 with high-pressure liquid in all directions, further enhancing the dust suppression effect. The ultrasonic system 33 can be an ultrasonic generator or an ultrasonic transducer.

[0040] The working principle of this application is as follows:

[0041] When the unloading vehicle 6 enters the rainproof frame 1, the stacking door 13 automatically closes, and the unloading vehicle 6 moves to the dwell area 12. The ultrasonic system 33 opens or closes, thereby controlling the opening or closing of the nozzle 34. When the unloading vehicle 6 enters the detection range of the sensor, the ultrasonic sensor sends a signal and transmits it to the control system. The controller opens the solenoid valve in the control system to control the nozzle 34 to open and close. The nozzle 34 effectively suppresses dust in the unloading area 4 to prevent dust from spreading from the unloading area 4 to other locations. After the unloading vehicle 6 completes unloading in the dwell area 12, the stacking door 13 automatically opens, and the unloading vehicle 6 drives away from the rainproof frame 1.

[0042] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
