Description

Technical Field

[0001] This utility model relates to the field of construction site dust suppression technology, specifically a construction site dust suppression device. Background Technology

[0002] During construction, a large amount of dust is generated, such as during earthwork excavation, material handling, and concrete mixing. To prevent the dust from affecting the health of construction workers and polluting the surrounding environment, mist cannons are usually used to spray water mist onto the construction site to suppress dust.

[0003] However, traditional fog cannons used to suppress dust at construction sites are usually directly connected to an external water source. When the water they spray comes into contact with metal building materials and machinery on the construction site, it can easily cause the metal parts to rust and corrode, which will seriously affect their service life and increase the frequency of equipment maintenance and replacement costs.

[0004] To address these issues, we offer dust suppression devices for construction sites. Utility Model Content

[0020] (iii) Beneficial effects:

[0021] Compared with existing technologies, this construction site dust suppression device has the following beneficial effects:

[0022] I. This construction site dust suppression device consists of a mixing tank and a solvent tank. A No. 1 water pump injects water-soluble rust inhibitor from the solvent tank into the mixing tank through a filling pipe. An external water source is also injected into the mixing tank through a water filling pipe. Under the action of a stirring rod and a stirring motor, the water and water-soluble rust inhibitor are mixed in the mixing tank. Then, a No. 2 water pump is activated to inject the mixed solution into a mist cannon. The mist cannon sprays the mixed solution onto the construction site to suppress dust. Because the solution contains water-soluble rust inhibitor, when the solution is sprayed onto metal parts on the construction site, it forms a protective film on the surface of the metal parts. This film can isolate the metal parts from air and moisture, prevent the metal parts from rusting, and thus extend the service life of the metal parts, reducing the equipment maintenance and replacement costs caused by rust.

[0023] II. This construction site dust suppression device features an electric telescopic rod for adjusting the vertical tilt angle of the fog cannon. A gear ring and gear mechanism, activated by a drive motor, cause the fog cannon to rotate via the interaction of the gears and gear ring, with the assistance of a support ring and a bracket ring. This allows for adjustment of the fog cannon's lateral angle. The combined action of the electric telescopic rod and drive motor expands the fog cannon's coverage area. Furthermore, it allows for precise targeting of the spray based on the actual location of dust generation. For example, when an excavator is digging in a specific area, the fog cannon can be quickly adjusted to the appropriate angle to suppress dust in that area, improving the targeting and effectiveness of dust suppression.

[0034] The lower end of the fog cannon 1 is equipped with a rotating base 2, and the lower end of the rotating base 2 is equipped with a mixing mechanism. The mixing mechanism includes: a mixing tank 3, a stirring rod 7, a solvent tank 9, a first water pump 10, and a second water pump 11. The two ends of the mixing tank 3 are respectively connected to a water inlet pipe 4 and a liquid addition pipe 5. Both the water inlet pipe 4 and the liquid addition pipe 5 are equipped with flow detectors 6. The water inlet pipe 4 is connected to an external water pipe and is used to add clean water into the mixing tank 3. The solvent tank 9 stores water-soluble rust inhibitor. The flow detectors 6 are set to facilitate the mixing of clean water and water-soluble rust inhibitor in proportion.

[0035] The stirring rod 7 is rotatably connected to the bottom of the mixing tank 3. The lower end of the mixing tank 3 is connected to the stirring motor 8. When the stirring motor 8 is started, it will drive the stirring rod 7 to rotate, thereby stirring the solvent in the mixing tank 3. The mixing tank 3 and the solvent tank 9 are both connected to the trolley to facilitate the movement of the device. The first water pump 10 is connected to the upper end of the solvent tank 9. The lower end of the first water pump 10 is connected to the inside of the solvent tank 9, and the upper end of the water outlet is connected to the liquid addition pipe 5. When the first water pump 10 is started, it will draw water-soluble rust inhibitor from the solvent tank 9 and then add it into the mixing tank 3 through the liquid addition pipe 5.

[0036] The solvent tank 9 is connected to a feed port at the top and a content detection tube 12 is connected to the outer end of the solvent tank 9. The content detection tube 12 is a transparent tube, and its lower end is connected to the solvent tank 9 for easy observation of the remaining amount of solution in the solvent tank 9. The lower end of the second water pump 11 is connected to the mixing tank 3, and the upper end of the water outlet is rotatably connected to the center point of the rotating seat 2, so that its water outlet will not obstruct the rotation of the rotating seat 2. The lower end of the mist cannon 1 is connected to a water guide pipe. One end of the water guide pipe is connected to the annular water pipe 101, and the other end is connected to a water guide hose, which is connected to the water outlet pipe of the second water pump 11.

[0037] The second water pump 11 is connected to the upper end of the mixing tank 3. The mixing tank 3 is connected to a partition plate 302. The water inlet pipe 4, the liquid addition pipe 5, and the stirring rod 7 are all located at the lower end of the partition plate 302, and the second water pump 11 is located at the upper end of the partition plate 302.

[0038] A support ring 301 is connected to the upper end of the mixing tank 3, and a support ring 201 is connected to the edge of the rotating seat 2. The support ring 201 is located above the support ring 301. Annular grooves are correspondingly opened in both, and ball bearings are installed in the annular grooves. The ball bearings are used to reduce the friction between the support ring 201 and the support ring 301, thereby facilitating the rotation of the rotating seat 2. A toothed ring 13 is connected inside the rotating seat 2. A drive motor 14 is connected to the upper end of the partition plate 302. A gear 15 is connected to the drive end of the drive motor 14. The gear 15 meshes with the toothed ring 13. When the drive motor 14 is started, it will drive the rotating seat 2 to rotate through the action of the gear 15 and the toothed ring 13.

[0039] Working principle: During use, connect the external water pipe to the inlet pipe 4, so that the external water source is injected into the mixing tank 3 through the inlet pipe 4. The first water pump 10 is started to draw water-soluble rust inhibitor from the solvent tank 9, and then add it into the mixing tank 3 through the liquid addition pipe 5. The stirring motor 8 is started to drive the stirring rod 7 to rotate, thereby mixing the solution in the mixing tank 3. The second water pump 11 is started to inject the mixed solution into the annular water pipe 101 through the water guide hose and water guide pipe, and then spray it out through the atomizing nozzle. The mist cannon 1 is started to spray water mist towards the workers. The mist cannon 1 is used to suppress dust. Because the mist contains water-soluble rust inhibitors, it forms a protective film on the surface of metal parts when it comes into contact with them. This film can isolate the metal parts from air and moisture, preventing them from rusting. During this process, the vertical angle of the mist cannon 1 can be adjusted by the electric telescopic rod 102. The start of the drive motor 14 is achieved by the action of the gear 15 and the gear ring 13. With the assistance of the support ring 201 and the support ring 301, the rotating seat 2 can drive the mist cannon 1 to rotate, thereby adjusting the horizontal angle of the mist cannon 1.
