Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction equipment, in particular to an open-pit mining dust suppressor. Background Art

[0002] With the advancement of the renovation and construction of old cities, many original infrastructure and construction layouts can no longer meet the current social needs, and a large number of buildings within the planned scope need to be demolished by blasting.

[0003] Since a large amount of dust is easily generated during the blasting demolition process, a fog cannon machine needs to be erected at the blasting site for dust reduction treatment. A fog cannon machine is an efficient dust removal device, which mainly atomizes water under high pressure and sprays it under the action of a strong blower. The atomized water combines with the dust in the air and adsorbs and settles to achieve the purpose of purifying the air.

[0004] Currently, the existing fog cannon machines usually include a water tank and a spray barrel. A strong blower is arranged inside the spray barrel. The strong blower includes a fan, and the fan is arranged towards the spray port direction of the spray barrel. By rotating the fan, strong wind is generated to achieve spraying. However, due to the extremely large impact force generated during the blasting process, sand and stones are likely to fly in the blasting site area. And since the spray port is always open, the flying stones are likely to enter the inside of the spray barrel through the spray port, directly hitting the fan, easily causing damage to the fan and affecting the service life of the equipment. Content of the Utility Model

[0005] The purpose of the utility model is to provide an open-pit mining dust suppressor to solve the above problems.

Detailed implementation manner

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] Please refer to Figure 1 , Figure 2 As shown, the open-pit mining dust suppression machine includes a water tank 1 and a spray tube 2. A spray opening is provided on the spray tube 2, and a protective device is provided at the spray opening. The protective device includes a mounting shell 3 fixedly connected to the spray opening, and a protective cover is detachably installed in the mounting shell 3. The protective cover includes a panel 4 for fitting into the interior of the mounting shell 3. A wire mesh eye shield 5 protruding outward is provided on the panel 4, and the wire mesh eye shield 5 is hemispherical. Through the setting of the protective cover, it can not only ensure that the spray tube 2 normally sprays water mist, but also block the flying stones from entering the interior of the spray tube 2 through the spray opening. Moreover, due to the convex spherical arc surface of the wire mesh eye shield 5, the stones will be quickly bounced off when flying onto the wire mesh eye shield 5, preventing them from getting stuck in the mesh holes and causing blockage. When the protective cover is deformed and damaged after long-term use, it can be removed from the mounting shell 3 for maintenance and replacement, always maintaining its protective effect. Through the protection of the protective cover, it can avoid the direct impact of flying stones on the fan and prevent the fan from being damaged, thus effectively ensuring the service life of the equipment. The wire mesh eye shield 5 is made of stainless steel material, with high strength and good corrosion resistance, thus ensuring the durability of the wire mesh eye shield 5.

[0023] Please refer to Figure 2-4As shown, through slots 6 are provided on both side walls of the mounting shell 3, and tongues 7 for penetrating the through slots 6 are provided on both sides of the inlay plate 4. The tongues 7 are retractable. When installing the protective cover, the inlay plate 4 can be embedded in the mounting shell 3, and then the tongues 7 are extended and penetrate the through slots 6. Then, the protective cover can be locked in the mounting shell 3 by limiting the tongues 7 by the through slots 6, so that a firm installation is achieved. When the protective cover needs to be removed, the tongues 7 can be shortened and withdrawn from the through slots 6, so that the lock of the protective cover can be released, and the inlay plate 4 can be conveniently pulled out from the mounting shell 3 to achieve the removal of the protective cover. This arrangement makes the disassembly and assembly of the protective cover more convenient and simple, thereby facilitating replacement and maintenance. An elastic frame 15 is provided on the panel 4, and the elastic frame 15 is made of rubber material. When the tongue 7 passes through the through slot 6, it will also pass through the elastic frame 15, so that the elastic frame 15 undergoes elastic deformation, and the deformed elastic frame 15 will then press against the tongue 7, thereby preventing the tongue 7 from easily falling out, effectively improving the installation firmness of the protective cover, wherein, cavities 8 are provided on both side walls of the panel 4, and the tongue 7 is slidably connected inside the cavity 8, so that the tongue 7 can extend or retract into the cavity 8 to achieve the extension and contraction of the tongue 7, and a slide groove 9 connected to the inside of the cavity 8 is provided on the panel 4, and a slider 10 slidably connected to the inside of the slide groove 9 is provided on the tongue 7, and a slide block 10 is connected between the slider 10 and the inner wall of the slide groove 9. An elastic member is connected, and the elastic member is used to keep the tongue 7 extending out of the cavity 8 in a natural state. When the panel 4 is embedded in the mounting shell 3, the tongue 7 is squeezed by the inner wall of the mounting shell 3 and will shrink into the cavity 8, thereby driving the slider 10 to slide along the slide groove 9. The slider 10 will squeeze the elastic member, causing it to undergo compression deformation. After the panel 4 is completely embedded in the mounting shell 3, the elastic member will break free from the pressure constraint and stretch and restore its original shape, thereby automatically popping the tongue 7 out of the cavity 8, making it elongate and pass through the through groove 6, and can elastically support the tongue 7, ensuring the clamping firmness of the tongue 7 and the through groove 6, thereby ensuring the installation firmness of the protective cover. The elastic member includes a raised section 11 , and a first connecting section 12 and a second connecting section 13 are respectively provided at both ends of the raised section 11, the first connecting section 12 is connected to the slider 10, and the second connecting section 13 is connected to the side wall of the slide groove 9. When the slider 10 squeezes the raised section 11, the compressed deformation will occur accordingly, and after the squeezing disappears, the raised section 11 will automatically stretch and restore its original shape, thereby ensuring the resilience of the elastic member. A paddle 14 is provided on the slider 10, and the slider 10 can be driven to slide by paddle 14. When it is necessary to release the lock of the protective cover, the paddle 14 can be paddled to make the slider 10 slide in the direction of the elastic member, so that the tongue 7 is retracted into the cavity 8, and the unlocking operation is realized. The operation is relatively convenient and simple, saving time and effort.
