Description

Technical Field

[0001] The utility model relates to the technical field of dust treatment, and more specifically, to a dust treatment device for construction engineering. Background Art

[0002] When excavation, crushing, and transportation are carried out at construction sites, the soil, sand, and other stones on the ground will be blown up to form dust. Construction sites are mostly dirt roads, and the movement of machinery and transportation vehicles on the site will also stir up the dust on the ground, which will also cause dust. Dust will cause the concentration of particulate matter in the air to increase, affecting the air quality of the surrounding areas and aggravating air pollution problems such as haze. At the same time, workers and surrounding residents may develop respiratory diseases by inhaling air containing particulate matter. Therefore, dust treatment devices are mainly used to reduce dust to comply with relevant regulations.

[0003] China Patent Authorization Announcement No. CN218774505U discloses an underground dust reduction spray device. A screw drives the dust reduction spray plate to move back and forth horizontally to spray dust. This eliminates the need for manual swinging and spraying. This back-and-forth movement provides a more uniform dust reduction spray, enhancing the suppression of phosphate dust, improving the working environment of phosphate mines, and eliminating safety hazards to ensure the normal and safe operation of phosphate mines. This device also reduces phosphate dust concentration, improves the working environment of phosphate mines, and automatically shuts off to prevent water accumulation and waste caused by prolonged spraying.

[0004] To reduce dust by spraying, a spray head is needed. The spray nozzle of a traditional spray head is always exposed to the outside. When not in use, the spray nozzle is also always exposed to the environment. At this time, the dust in the construction site environment is easy to adhere to the spray nozzle. After a long period of non-use, the dust is easy to harden and block the spray nozzle.

[0005] Therefore, in order to solve the above problems, a dust treatment device for construction engineering is proposed. Utility Model Content

When the magnet 57 slides to the bottom of the slide groove 55, the spray port 56 is located inside the slide groove 55 and is not connected to the outside world.

[0032] When excavation, crushing, and transportation are carried out at construction sites, the soil, sand, and gravel on the ground will be blown up to form dust. At the same time, the movement of machinery and transport vehicles on the construction site will also stir up the dust on the ground, causing dust. Dust will affect the air quality of the surrounding areas. Therefore, dust reduction devices are currently required during construction on construction sites, and water or spraying are usually used to reduce dust.

[0033] The guardrail 1 in this scheme is frequently used on construction sites, and the fixing component 3 is installed at the top of the guardrail 1. A support frame 2 is installed at the outer end of the fixing component 3. The support frame 2 is mainly used to assist the fixing component 3 in being fixed on the guardrail 1. It is also used to support the guardrail 1 to make the guardrail 1 more stable. A connecting component 6 is installed on the outside of the fixing component 3. The connecting component 6 is mainly used to install the spray component 4. The anti-blocking component 5 is installed on the inside of the spray component 4. When water enters the water tank 54 from the inside of the spray component 4, the anti-blocking shell 52 inside the chute 55 will be pushed upward by the water pressure. At this time, the spray ports 56 on both sides of the anti-blocking shell 52 will extend to the outside to start spraying. When the water supply is stopped, the anti-blocking shell 52 can be retracted into the chute 55 and reset through the magnetic attraction between magnet 1 57 and magnet 2 59, so that the spray port 56 will not be exposed to the outside, thereby preventing the spray port 56 from being blocked.

[0034] See also Figure 1-Figure 3 The fixing assembly 3 includes a fixing plate 31, which is fixedly installed on the top of the guardrail 1. The outer end of the fixing plate 31 is rotatably connected to a plurality of mounting hooks 33.

[0035] The connecting assembly 6 includes a connecting plate 61 , an outer end of which is mounted with a U-bolt 62 , and the connecting plate 61 is rotatably connected to the outer end of the extension plate 32 .

[0036] The fixing assembly 3 in this scheme is mainly used to install the spray assembly 4 on the guardrail 1, wherein the fixing plate 31 is U-shaped, so that it can be sleeved on the frame at the top of the guardrail 1 from top to bottom. A plurality of bolts are threadedly connected on the side of the fixing plate 31 away from the mounting hooks 33. By rotating and tightening the bolts, it is pressed against the guardrail 1, so that the fixing plate 31 can be fixed. On the other side of the fixing plate 31, two mounting hooks 33 are rotatably connected. The mounting hooks 33 clamp the support frame 2 through their concave grooves, fixing the support frame 2 on the fixing plate 31, so that the support frame 2 can be rotated to support the guardrail 1. At the same time, it can also assist in fixing the fixing plate 31. By adjusting the rotation angle of the support frame 2, it can be suitable for guardrails 1 of different heights. It is worth mentioning that a ground cone can be installed at the bottom of the support frame 2 to insert it into the ground, or a heavy object such as bricks can be used to press the bottom of the support frame 2 so that it can better support the guardrail 1.

[0037] The connecting assembly 6 is mainly composed of a connecting plate 61 and a U-shaped bolt 62. The extension plate 32 is fixed to the top of the fixed plate 31. The connecting plate 61 and the extension plate 32 are rotatably connected. A bolt can pass through the connecting plate 61 and the extension plate 32, and then two nuts are used to lock them. When the connecting plate 61 needs to be rotated, the nuts can be loosened. By rotating the connecting plate 61, the angle of the spray assembly 4 can be adjusted, so that the anti-blocking assembly 5 can change the angle of the spray.

[0038] Both ends of the U-shaped bolt 62 are inserted into the connecting plate 61 and fixed with a nut. A fixing groove 43 is opened at the outer end of the cylinder 41, and the fixing groove 43 matches the U-shaped bolt 62. The fixing groove 43 is clamped and locked by the U-shaped bolt 62, and the cylinder 41 can be installed on the outside of the connecting plate 61 and rotate with it.

A fixing groove 43 is opened at the outer end of the cylinder 41. The cylinder 41 is mounted on the outside of the connecting plate 61 through the fixing groove 43 and the U-bolt 62.

[0041] The spray assembly 4 in this scheme is mainly used to deliver water to the anti-blocking assembly 5, and finally the spray is performed through the anti-blocking assembly 5. A water delivery port 42 is fixed on the outside of the cylinder 41. The water delivery port 42 is connected to the inside of the cylinder 41, and the water delivery port 42 needs to be connected to an external water pipe for supplying water to the inside of the cylinder 41. Two symmetrically arranged card blocks 44 are fixed on the outside of the top of the cylinder 41. The card blocks 44 protrude outward and are mainly used to engage with the outer cap 45. The inner side of the outer cap 45 is provided with a card slot. By engaging with the card blocks 44, the card slot is formed. The card can be detachably installed on the top of the cylinder 41. A filtering device 46 is also provided inside the cylinder 41. The filtering device 46 is detachable and can be installed or removed as needed. The filtering device 46 is mainly made of a filter mesh, which is used to filter impurities in the water to prevent the anti-blocking component 5 from being blocked. The anti-blocking component 5 is installed on the top of the cylinder 41 and is fixed by an outer cap 45. The outer cap 45 is mainly used to fix the anti-blocking component 5. Water can be transported to the anti-blocking component 5 through the spray component 4.

[0042] See also Figures 1-6 A water trough 54 is provided inside the nozzle 51, and the water trough 54 is connected to the chute 55. A plurality of magnets 59 are fixedly installed at the bottom end of the chute 55. The magnets 59 and 57 are adapted to each other. The chute 55 is connected to the inside of the anti-blocking shell 52.

[0043] A sealing cover 58 is fixedly installed on the top of the anti-blocking shell 52, and a sealing groove 53 adapted to the sealing groove 53 is opened on the top of the nozzle 51. When the sealing cover 58 matches the sealing groove 53, a seal is formed on the slide groove 55.

[0044] The anti-blocking component 5 in this scheme is mainly used for spraying. The nozzle 51 is installed inside the top end of the cylinder 41. A water trough 54 is provided inside the nozzle 51. The water trough 54 is connected to the interior of the cylinder 41. A chute 55 is provided inside the cylinder 41, that is, above the water trough 54. The chute 55 is connected to the water trough 54, so that water can enter the chute 55. The anti-blocking shell 52 is arranged inside the chute 55. The interior of the anti-blocking shell 52 is hollow and is connected to the interior of the chute 55. Magnets 1 57 are fixed on both sides of the anti-blocking shell 52, and a plurality of magnets 2 59 are fixed at the bottom end of the chute 55, that is, in the area separated from the water trough 54. Magnets 2 59 and magnets 1 57 are attracted to each other by magnets, so that the anti-blocking shell 52 can be sucked inward so that the anti-blocking shell 52 is located in the chute 55.

[0045] After the water is discharged from the nozzle 56, the nozzle 56 is turned off, and the nozzle 56 is turned off.

[0046] A sealing cover 58 is fixed on the top of the anti-blocking shell 52, and a sealing groove 53 matching the sealing cover 58 is opened on the top of the nozzle 51. When the anti-blocking shell 52 is reset, the sealing cover 58 will also match the sealing groove 53, covering the top of the slide groove 55, thereby forming a sealed state to prevent dust from entering.

[0047] Working principle: When using the device for spray dust suppression, first install the fixing assembly 3 on the guardrail 1, and put the fixing plate 31 on the frame at the top of the guardrail 1 from top to bottom. Turn and tighten the bolts to fix it on the guardrail 1. Connect the water pipe to the water inlet 42 for water supply. When the high-pressure water in the cylinder 41 flows into the chute 55 and the anti-blocking shell 52 through the water trough 54, the anti-blocking shell 52 will move upward due to the water pressure. When the spray port 56 is separated from the chute 55, the high-pressure water will be sprayed out from the spray port 56 to form atomized small water droplets.

[0048] When the anti-blocking shell 52 loses water pressure after the spraying stops, the anti-blocking shell 52 will be reset due to the magnetic attraction between the magnet 1 57 and the magnet 2 59, so that the spray port 56 will not be exposed to the outside. Even if it is not used for a long time, external dust will not accumulate on the spray port 56 and block it.
