Description

Technical Field

[0001] The utility model relates to the technical field of blasting engineering, in particular to a dust suppression device for blasting engineering. Background Art

[0002] Since large amounts of dust are easily generated during blasting and demolition, it is necessary to set up a fog cannon at the blasting site for dust reduction. The fog cannon is a highly efficient dust removal device that mainly uses high pressure to atomize water and then sprays it out under the action of a strong fan. The atomized water combines with the dust in the air and adsorbs and settles to purify the air.

[0003] At present, the existing fog cannon usually includes 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 toward the spray port of the spray barrel. The rotation of the fan creates strong wind to achieve spraying. However, due to the great impact force generated during the blasting process, sand and gravel are easily splashed within the blasting site. Since the spray port is open for a long time, the splashed stones are easy to enter the interior of the spray barrel through the spray port, thereby causing a direct blow to the fan, which is easy to cause damage to the fan and affect the service life of the equipment. Utility Model Content

[0004] The purpose of the utility model is to provide a dust suppression device for blasting engineering in order to solve the above-mentioned problem, which can effectively protect the components inside the spray barrel and has a long service life.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 As shown, a dust suppression device for blasting engineering includes a water tank 1 and a spray barrel 2, a spray port 3 is provided on the spray barrel 2, and a protective plate 4 is arranged on the spray port 3, the protective plate 4 is made of stainless steel material, has high strength and hardness, and is not easy to rust, thereby ensuring the strength of the protective plate 4, so that the protective plate 4 has good protection ability, a plurality of mist outlet holes 5 are provided on the protective plate 4, the mist outlet holes 5 are connected with the inside of the spray barrel 2, and a plurality of elastic baffles 6 are arranged inside the mist outlet holes 5, the elastic baffles 6 are all fan-shaped, and one end of the elastic baffles 6 is fixedly connected to the inner wall of the mist outlet hole 5, and the other ends are mutually opposed and are arranged toward the outside of the mist outlet hole 5, so that during the use of the device, the protective plate 4 can block the splashing stones from entering the inside of the spray barrel 2 through the spray port 3, and the elastic baffles 6 can block the dust impurities. The water mist enters the interior of the spray barrel 2 through the mist outlet hole 5, thereby effectively protecting the components inside the spray barrel 2 and extending the service life of the device. During spraying, the water mist can still push open the elastic baffles 6 that conflict with each other under the action of high pressure, so that it can be smoothly sprayed out from the mist outlet hole 5. Since the water mist is diverted through multiple mist outlet holes 5, it is made finer and has a good dust reduction effect. After the spraying is completed, the elastic baffle 6 can automatically reset and conflict again to close the mist outlet hole 5, thereby achieving a good dust prevention effect. A buffer gasket 7 is arranged on the protective plate 4, and the buffer gasket 7 is made of rubber material with good elasticity and toughness. When the flying stones collide with the buffer gasket 7, the buffer gasket 7 can actively deform to mitigate the impact, thereby preventing the stones from directly hitting the protective plate 4 and causing the protective plate 4 to deform, thereby improving the durability of the protective plate 4 and enhancing the protective ability of the protective plate 4.

[0023] See also Figure 1-5As shown, the protective plate 4 is detachably mounted on the spray port 3. When the protective plate 4 is deformed and damaged due to long-term use, the protective plate 4 can be removed from the spray port 3 in time for replacement, thereby ensuring the protective effect of the device, and a handle 16 is provided on the protective plate 4. When the protective plate 4 needs to be removed, the handle 16 can be held and force can be applied. The handle 16 can be used as a force application point, making the operation easier and more labor-saving. A mounting shell 8 for embedding the protective plate 4 is provided on the spray port 3, and a plurality of through grooves 9 are opened on the bottom wall of the mounting shell 8. The plate 4 is provided with a plurality of blocks 10 for penetrating the through slots 9, and a locking assembly for engaging with the blocks 10 is provided at the bottom of the mounting shell 8. When installing the protective plate 4, the protective plate 4 can be first embedded in the mounting shell 8, so that the blocks 10 then penetrate the through slots 9 and pass out from the bottom of the mounting shell 8, and then the locking assembly and the blocks 10 can be engaged with each other to achieve locking of the protective plate 4. When it is necessary to remove the protective plate 4, the locking assembly and the blocks 10 can be released first to unlock the protective plate 4, and then the blocks 10 can be pulled out from the through slots 9 to remove the protective plate 4. The plate 4 is removed from the inside of the mounting shell 8. Through this arrangement, the disassembly and assembly of the protective plate 4 becomes more convenient and simple, saving time and effort. The locking assembly includes a pin seat 11 fixed to the bottom of the mounting shell 8 and a latch 12 slidably connected to the inside of the pin seat 11, and a slot 13 for inserting the latch 12 is opened on the card block 10. After the protective plate 4 is embedded in the mounting shell 8 and the card block 10 passes through the through groove 9, the latch 12 can be pushed out from the inside of the pin seat 11 and inserted into the inside of the slot 13. The protective plate 4 can be locked by limiting the position of the latch 12 by the slot 13. The locking ensures that the protective plate 4 is firmly installed inside the mounting shell 8. When the protective plate 4 needs to be removed, the limit can be released by simply pulling the latch 12 out of the slot 13, thereby facilitating the removal of the protective plate 4. A slideway 14 is provided on the pin seat 11 along the length direction, and a paddle 15 slidably connected to the inside of the slideway 14 is provided on the latch 12. When it is necessary to push the latch 12 to extend or retract into the pin seat 11, the paddle 15 can be moved to apply force, and the paddle 15 can be used as a force point to push the latch 12 to slide, thereby making the operation easier and more labor-saving.
