Description

Technical Field

[0001] This utility model relates to the technical field of dust treatment devices, specifically to a dust collection and purification device. Background Technology

[0002] During open-pit mining operations, drilling, blasting, excavation, and transportation generate large amounts of dust. This dust not only contains harmful substances such as silicon and heavy metals, which can seriously damage the respiratory and cardiovascular systems of workers and cause occupational diseases such as pneumoconiosis, but it also spreads with the wind to the surrounding environment, polluting the atmosphere, soil, and water sources, and disrupting the ecological balance. With increasingly stringent environmental protection requirements and greater emphasis on occupational health and safety, the effective collection and purification of dust from open-pit mining has become a critical issue that urgently needs to be addressed.

[0003] The invention patent with authorization announcement number CN112169501B discloses a dust purification system, including a dust collection device and a particle forming device disposed on the dust collection device for simultaneously injecting a gaseous medium and a fluid medium into the dust collection device. The dust collection device includes a processing chamber and a dust suction and removal integrated structure disposed on the processing chamber for collecting dust and injecting the dust into the processing chamber. The particle forming device includes an ejection component embedded in and penetrating through the side wall of the processing chamber. In use, the particle forming device can simultaneously inject a gaseous medium and a fluid medium into the processing chamber, further enabling the dust collected by the suction structure to mix with the fluid medium to form large dust particles. This not only avoids the problem of small dust particles being difficult to collect, but also accelerates the settling of dust inside the system during use, effectively improving the dust collection efficiency.

[0004] While this technical solution has the advantage of accelerating dust settling within its interior and effectively improving dust collection efficiency, current mainstream solutions generally integrate multiple methods for dust treatment, such as various spraying and filtration methods. This results in a large and heavy device that can only be fixed in a specific location, making it unsuitable for open-pit mining operations. Furthermore, traditional purification devices are generally difficult to move and cannot be moved and stably positioned within the corresponding mining area as mining progresses, affecting their effectiveness. Therefore, we propose a dust collection and purification device. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-3 This utility model provides a technical solution: a dust collection and purification device, including a water storage purification tank 1. A filter screen 14 is detachably connected inside the upper part of the water storage purification tank 1. An air outlet pipe 17 is fixedly installed on the top side of the water storage purification tank 1, located above the filter screen 14. An air suction fan 2 is provided on one side of the water storage purification tank 1. The air suction fan 2 can be a rotary fan, and this is a conventional technology, which will not be described in detail here. A conveying pipe 20 is fixedly installed at the air outlet end of the air suction fan 2. A uniform distribution cover 21 is fixedly installed at the air outlet end of the conveying pipe 20. The uniform distribution cover 21 is located inside the water storage purification tank 1 and below the filter screen 14, enabling the air suction fan 2 to convey dust to the water in the water storage purification tank 1 for wetting treatment, and then further filtering through the filter screen 14, ensuring the dust treatment effect.

[0034] like Figure 1 and Figure 3As shown, the bottom of the water purification tank 1 is fixedly equipped with multiple rollers 11, enabling the water purification tank 1 to move flexibly at the open-pit mining site. This realizes the function of rapid transfer of the device according to the mining progress, effectively solving the problem of the difficulty in moving traditional devices and improving the convenience and flexibility of use. On the left and right sides of the bottom box of the water purification tank 1, two symmetrical fixing frames 3 are fixedly installed. The fixing frame 3 includes a side plate 30 fixedly installed on the water purification tank 1. A soil insertion rod 31 is inserted into the side plate 30. A limiting plate 32 is fixedly installed on the soil insertion rod 31. A central hole 301 is provided in the side plate 30 along the vertical direction. The soil insertion rod 31 is inserted into the central hole 301. The size of the soil insertion rod 31 is adapted to the size of the central hole 301. The outer diameter of the limiting plate 32 is larger than the diameter of the central hole 301, so that the water purification tank 1 can be firmly fixed to the ground after arriving at the mining area, avoiding displacement of the device under complex working conditions and ensuring the stability and safety of the device operation.

[0035] In this embodiment, the limiting plate 32 is used to abut against the top surface of the side plate 30 or support the bottom surface of the side plate 30. At this time, according to the actual situation on site, the soil insertion rod 31 is inserted into the soil along the central hole 301, and the limiting plate 32 is used to abut against the top surface of the side plate 30 for limiting; or part of the soil insertion rod 31 is directly inserted into the soil, and then the side plate 30 is put on the soil insertion rod 31, so that the limiting plate 32 is used to support the bottom surface of the side plate 30 for support.

[0036] like Figure 1 As shown, the top of the water purification tank 1 is connected to the outside. A top cover 16 is hinged to one side of the top surface of the water purification tank 1. A handle 161 is fixedly installed on the top surface of the top cover 16, which connects the top of the water purification tank 1 to the outside. With the handle 161 on the top surface, it is convenient for operators to open the top cover 16 to add water and clean the inside of the tank, which reduces the maintenance difficulty of the device and ensures the continuous and effective operation of the purification treatment.

[0037] like Figure 1 As shown, a support plate 18 is fixedly installed on the side of the water purification tank 1, and the suction fan 2 is fixedly installed on the support plate 18 to support the suction fan 2.

[0038] like Figure 1 As shown, a drain pipe 12 is fixedly installed on one side plate at the bottom of the water storage and purification tank 1. A valve 121 is fixedly installed on the drain pipe 12. An inclined surface 10 is provided on the bottom surface of the water storage and purification tank 1. The inclined surface 10 is set at a downward angle of 15° to 30° towards the drain pipe 12, so that the sewage in the tank can be quickly discharged along the drain pipe 12 under the action of gravity, which improves the sewage cleaning efficiency and facilitates the cleaning and maintenance of the device.

[0039] like Figure 1 and Figure 2 As shown, a support ring 13 is fixedly installed on the inner wall of the upper half of the water purification tank 1, and a fixing ring 141 is fixedly installed on the outer annular side of the filter screen 14. The fixing ring 141 is detachably installed on the top surface of the support ring 13, so that the filter screen 14 can be detachably installed in the upper half of the water purification tank 1. This makes it convenient for operators to install, remove and replace the filter screen 14, ensuring that the filter screen 14 continues to perform its filtering effect and improving the device's dust purification capability.

[0040] like Figure 1 As shown, two sets of symmetrical guide plates 15 are fixedly installed on the inner wall of the water storage and purification tank 1. The two sets of guide plates 15 are arranged alternately, and the cross section of the guide plate 15 is inverted V-shaped. The guide plate 15 is located below the filter screen 14. Gas gaps 151 are provided between two adjacent guide plates 15 to form a tortuous airflow channel in the water storage and purification tank 1, so that the exhaust gas and water can come into more complete contact, increasing the chance of dust being soaked in the water, improving the dust settling efficiency, and further improving the purification effect of the device.

[0041] When using the dust collection and purification device of this utility model, firstly, push the water storage and purification tank 1 and use the bottom rollers 11 to move the device to the dust generation area of ​​the open-pit mining. After reaching the designated position, according to the soil conditions on site, insert the soil insertion rod 31 in the fixing frame 3 into the soil along the center hole 301 of the side plate 30. The limiting plate 32 is used to abut against the top surface of the side plate 30. Alternatively, first insert the soil insertion rod 31 into the soil, and then put the side plate 30 on the soil insertion rod 31. The limiting plate 32 is used to support the bottom surface of the side plate 30 to achieve stable fixation of the device. Then, the operator holds the handle 161 on the top cover 16 to open the top cover 16 and adds an appropriate amount of water into the water storage and purification tank 1 until the water submerges the filter screen 14. After that, close the top cover 16.

[0042] Next, the suction fan 2 is started. The dust-laden gas is evenly sent into the water in the water purification tank 1 through the suction fan 2, the delivery pipe 20, and the uniform distribution cover 21. The dust is wetted and settles. Then, the gas continues to rise and passes through the staggered inverted V-shaped guide plates 15, making more full contact with the water and further settling the dust. Finally, the gas passes through the filter screen 14 for secondary filtration, and the purified gas is discharged from the exhaust pipe 17. When it is necessary to clean the sewage in the tank, the valve 121 on the sewage pipe 12 is opened, and the sewage is quickly discharged under the guidance of the inclined surface 10 at the bottom of the water purification tank 1. If the filter screen 14 needs to be replaced, the fixing ring 141 is removed, the old screen can be removed and the new filter screen 14 can be installed.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
