Abstract
Description
Technical Field
[0001] This utility model relates to a dust control device, specifically a dust control device for construction engineering, and belongs to the field of dust control technology. Background Technology
[0002] Construction dust is mainly generated by dust, construction materials, and vehicle movement at the construction site. Based on its cause, dust can be divided into primary and secondary dust. Primary dust mainly occurs when handling bulk materials, such as dismantling and mixing bulk cement. The induced airflow carries dust from the materials being processed, polluting localized areas. Secondary dust occurs when airflow caused by ventilation moves floating dust, re-erecting dust that has settled on equipment, floors, and building structures. Dust control typically involves spraying water in atomized form; the small water droplets contact the dust in the air to suppress it.
[0003] Currently, dust control in construction projects involves pumping water from a tank and spraying it onto the dusty area through water pipes. However, the length of a single water pipe is limited, making it difficult to completely suppress dust in larger dusty areas. It is also difficult to connect multiple water pipes to a single pipe and store them when not in use. Furthermore, the length of the water pipe cannot be adjusted according to the extent of the dust, which is not conducive to large-scale dust suppression. Utility Model Content
[0004] The purpose of this invention is to provide a dust control device for construction projects to solve the above problems. It can extend the length of the water spray pipe, is suitable for dust suppression of different areas, and can quickly store the extended water spray pipe when not in use.
[0005] This utility model achieves the above-mentioned objective through the following technical solution: a dust control device for construction engineering, comprising a shell, a water inlet cylinder, and a conveying mechanism. The water inlet cylinder is installed on the shell. A dust suppression mechanism is detachably connected to the conveying mechanism. The dust suppression mechanism includes a support frame. The support frame is installed on the shell. A movable joint is fixedly connected to the support frame. One end of the movable joint is connected to the conveying mechanism, and the other end of the movable joint is connected to a connecting pipe. A first spray pipe is vertically connected to the end of the connecting pipe. Spray nozzles are equidistantly installed on the first spray pipe. An expansion mechanism is installed on the first spray pipe. The expansion mechanism includes two fixing rings. Two fixing rings are diagonally fixedly connected to the first spray pipe. Second spray pipes are slidably connected to both fixing rings. Two first connectors are diagonally fixedly connected to the first spray pipe. Second connectors are diagonally fixedly connected to the two second spray pipes. A middle pipe is slidably connected to each of the two second connectors. The end of the middle pipe abuts against the first connector. Springs are clamped between the two second spray pipes and the middle pipes.
[0006] Preferably, the cross-section of the first connector is T-shaped, and the cross-section of the second connector is inverted T-shaped.
[0007] Preferably, the expansion mechanism further includes a slide bar, and the bottom of each of the two second nozzles is fixedly connected to a slide bar with an inverted T-shaped cross-section, and the slide bar is slidably connected to the fixing ring.
[0008] Preferably, the extension mechanism further includes two fixing seats, which are diagonally fixedly connected to the first nozzle, and the opening of the fixing seats is larger than the diameter of the middle pipe.
[0009] Preferably, the expansion mechanism further includes baffles, and baffles are fixedly connected to both ends of the two second nozzles.
[0010] Preferably, the expansion mechanism further includes sealing rings, with sealing rings provided between the two first connectors and the intermediate tube, and between the two second connectors and the intermediate tube.
[0011] Preferably, the conveying mechanism includes a water pipe, which is installed on the outer casing. The end of the water pipe is connected to a movable joint. A water pump is installed inside the outer casing and connected to the water pipe. An air tank is installed inside the outer casing and connected to an air pipe, which is connected to the water pipe.
[0012] Preferably, a support mechanism is installed on the outer shell. The support mechanism includes two side plates. The two side plates are fixedly connected to each other on both sides of the bracket. Insert plates are slidably connected to both side plates.

[0014] The beneficial effects of this utility model are as follows: When the area requiring dust suppression is large, the second nozzle on the fixing ring can be pulled. When pulling, the middle tube is squeezed towards the second nozzle, and the spring contracts, ensuring that the middle tube can move to the first connector on the first nozzle. When the middle tube moves above the first connector, the middle tube is released, the spring returns to its original position, and the middle tube further contacts and connects with the first connector. At this time, the first nozzle and the second nozzle are connected, which increases the area of water spraying and is beneficial for suppressing dust over a large area. When storing, the middle tube is squeezed towards the second nozzle, and the second nozzle is moved to the designated position and the middle tube is released to limit the second nozzle.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0024] Please see Figure 1-7As shown, a dust control device for construction engineering includes a housing 1, a water inlet cylinder 3, and a conveying mechanism 4. The water inlet cylinder 3 is mounted on the housing 1. A dust suppression mechanism 5 is detachably connected to the conveying mechanism 4. The dust suppression mechanism 5 includes a bracket 501. The bracket 501 is mounted on the housing 1. A movable joint 502 is fixedly connected to the bracket 501. One end of the movable joint 502 is connected to the conveying mechanism 4, and the other end of the movable joint 502 is connected to a connecting pipe 505. A first spray pipe 503 is vertically connected to the end of the connecting pipe 505. Spray nozzles 504 are equidistantly mounted on the first spray pipe 503. An extension mechanism 7 is installed on the first nozzle 503. The extension mechanism 7 includes two fixing rings 701. Two fixing rings 701 are fixedly connected to the first nozzle 503 at an angle. A second nozzle 702 is slidably connected to each of the two fixing rings 701. Two first connectors 706 are connected to the first nozzle 503 at an angle. A second connector 708 is fixedly connected to each of the two second nozzles 702 at an angle. A middle tube 710 is slidably connected to each of the two second connectors 708. The end of the middle tube 710 abuts against the first connector 706. A spring 709 is clamped between each of the two second nozzles 702 and the middle tube 710.
[0025] As a technical optimization of this utility model, the cross-section of the first connector 706 is T-shaped, and the cross-section of the second connector 708 is inverted T-shaped, thereby limiting the position of the intermediate tube 710.
[0026] As a technical optimization of this utility model, the extension mechanism 7 further includes a slide bar 703. The bottom of each of the two second nozzles 702 is fixedly connected to a slide bar 703 with an inverted T-shaped cross section. The slide bar 703 is slidably connected to the fixing ring 701 to prevent the second nozzles 702 from rotating radially.
[0027] As a technical optimization of this utility model, the expansion mechanism 7 further includes two fixing seats 704. Two fixing seats 704 are fixedly connected diagonally to the first nozzle 503. The opening of the fixing seat 704 is larger than the diameter of the intermediate tube 710, so that when the second nozzle 702 is stored, the intermediate tube 710 abuts against the fixing seat 704 to complete the storage. The expansion mechanism 7 also includes baffles 705. Both ends of the two second nozzles 702 are fixedly connected to baffles 705 to prevent the second nozzles 702 from detaching from the fixing ring 701. The expansion mechanism 7 also includes sealing rings 707. Sealing rings 707 are provided between the two first connectors 706 and the intermediate tube 710, and between the two second connectors 708 and the intermediate tube 710 to increase the sealing performance of the connection between the intermediate tank 710 and the first connectors 706 and the second connectors 708.
[0028] As a technical optimization of this utility model, the conveying mechanism 4 includes a water pipe 401, which is installed on the outer shell 1. The end of the water pipe 401 is connected to the movable joint 502. A water pump 404 is installed inside the outer shell 1 and is connected to the water pipe 401. An air storage tank 403 is installed inside the outer shell 1 and is connected to an air pipe 402. The air pipe 402 is connected to the water pipe 401. When dust is being suppressed, the water pump 404 and the air pipe 402 are activated to atomize and spray water to suppress dust.
[0029] As a technical optimization of this utility model, a support mechanism 6 is installed on the outer shell 1. The support mechanism 6 includes two side plates 601. The two side plates 601 are fixedly connected to each other on both sides of the bracket 501. Insert plates 602 are slidably connected to both side plates 601. Arc-shaped retaining rings 603 are fixedly connected to the ends of both insert plates 602. The retaining rings 603 are inserted into the first nozzle 503. When the first nozzle 503 and the second nozzle 702 are working, the first nozzle 503 can be horizontally fixed by the insert plates 602 and the retaining rings 603 to prevent it from tilting and affecting dust suppression.
[0030] As a technical optimization of this utility model, a moving mechanism 2 is installed on the outer shell 1. The moving mechanism 2 includes two fixed plates 201. The two fixed plates 201 are fixedly connected to the side of the outer shell 1. A push rod 202 is fixedly connected between the two fixed plates 201. Rollers 203 are installed at the four corners of the bottom of the outer shell 1. Pushing the push rod 202 enables the rollers 203 to move on the ground, which is conducive to the transportation of the whole structure.
[0031] When using this invention to suppress dust at construction sites, the push rod 202 moves the roller 203 on the ground, facilitating the movement of the overall structure. Water is added to the inside of the outer casing 1, and the air pipe 402 and water pipe 402 are opened, allowing the water pump 404 to deliver water from inside the outer casing 1 into the water pipe 401. The water is then sprayed from the nozzle 504 on the first spray pipe 503 through the connecting pipe 505. The sprayed water droplets suppress dust. While the first spray pipe 503 is spraying water, the insert plates 602 on the two side plates 601 can be slid to insert the retaining ring 603 into the outside of the first spray pipe 503, providing support and preventing tilting during dust suppression. When the area requiring dust suppression is large, the second spray pipe 702 on the fixing ring 701 can be pulled. When pulling, the middle pipe 710 is moved towards the second spray pipe 702. When the second nozzle 702 is pressed in the direction of the second nozzle 702, the spring 709 contracts, ensuring that the intermediate tube 710 can move to the first connector 706 on the first nozzle 503. When the intermediate tube 710 moves above the first connector 706, the intermediate tube 710 is released, the spring 709 returns to its original position, and the intermediate tube 710 further contacts and connects with the first connector 706. At this time, the first nozzle 503 and the second nozzle 702 are connected, increasing the area of water spraying and facilitating dust suppression over large areas. When storing, the intermediate tube 710 is pressed towards the second nozzle 702, and the intermediate tube 710 is moved above the fixed base 704 and released. The intermediate tube 710 is then inserted into the interior of the fixed base 704 to prevent the second nozzle 702 from opening during storage. The retaining ring 603 is then removed from the first nozzle 503, and the first nozzle 503 is rotated vertically, which reduces the space occupied and facilitates transportation.
