Description

Technical Field

[0001] This utility model belongs to the field of dust removal and environmental protection technology, specifically relating to a dust removal device for building construction. Background Technology

[0002] A dust collector is a device that separates dust from flue gas. It is often used in places such as construction sites where a large amount of construction machinery and building materials are present, which will generate a large amount of high-concentration coarse-particle dust. Commonly used atomizing dust collectors consume a lot of water resources to remove a large amount of high-concentration coarse-particle dust. Therefore, a more resource-saving and efficient dust removal method is needed.

[0003] For example, an existing dust removal mechanism for construction sites with patent number CN220939756U achieves multi-angle spraying dust removal through rotating atomizing nozzles and dust suction through dry dust removal components. However, the air inlet of its fan is located below the atomizing nozzles. At the same time, water mist and dust are simultaneously sucked into the fan during operation, forming mud that adheres to the fan or dust removal pipe, affecting the dust removal effect. Therefore, a dust removal device that can achieve both spraying and safe dust suction is needed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a construction dust removal device that addresses the shortcomings of the prior art. This device has a simple structure and reasonable design. By incorporating a dry dust collection mechanism, it facilitates the extraction of dust and other polluting gases from the air. The dust is then filtered through a stainless steel mesh and activated carbon adsorption mesh within the dust collection box. A wet dust suppression mechanism allows for water mist dust suppression operations behind the dry dust collection mechanism, achieving a dual air purification effect. Furthermore, a baffle plate located above the fan protects the equipment from being sprayed with large amounts of continuous water mist, reducing the risk of damage and resulting in good performance.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a construction dust removal device, including a base plate, a dry dust collection mechanism and a wet dust suppression mechanism located on the upper part of the base plate, and a water baffle and an installation plate are arranged in sequence above the base plate;

[0006] The dry dust collection mechanism includes a dust collection box, an air inlet pipe disposed on one side of the dust collection box, and a fan disposed on the other side of the dust collection box. The dust collection box is placed on a base located on the upper part of the base plate, and the fan is installed on the lower part of the baffle plate.

One end of the dust collection bag is connected to the air inlet, and a filter box is provided between the other end of the dust collection bag and the exhaust port. The filter box includes a stainless steel interception mesh and an activated carbon adsorption mesh.

[0008] The wet dust suppression mechanism includes a water tank mounted on the base, a high-pressure water pump mounted on the baffle plate, and a rotary spray pipe mounted on the mounting plate. A water outlet pipe connects the water tank and the high-pressure water pump, and a spray pipe connects the high-pressure water pump and the rotary spray pipe. The other end of the rotary spray pipe is connected to a multi-head atomizing nozzle. A second support frame for tilting the spray pipe is provided on the mounting plate.

[0009] Furthermore, the bottom of the base plate is provided with four casters, one end of the base plate is provided with a push rod, the base plate is provided with four first support columns for supporting the water baffle, and the water baffle is provided with four second support columns for supporting the mounting plate.

[0010] Furthermore, a dust collection hood is provided on the handheld part of the air intake pipe.

[0011] Furthermore, a stop valve is installed on the water spray pipe.

[0012] Furthermore, the first support frame is a U-shaped elastic plastic bracket, and the first support frame is tilted upward and away from the dust collection box.

[0013] Furthermore, the second support frame is a hinge support, the bottom of the hinge support is a flat plate, the top of the hinge support is an inclined plate, and the inclined plate is provided with binding straps for fixing the water spray pipe.

[0014] This utility model has the following advantages compared with the prior art:

[0015] 1. This utility model is simple and quick to operate. By setting up a dry dust collection mechanism, it is easy to extract dust and other polluting gases from the air. Then, the gases are filtered through the stainless steel interception mesh and activated carbon adsorption mesh in the dust collection box, and then the purified gases are discharged by the fan. At the same time, by setting up a dust collection bag, it is easy to collect solid particles intercepted by the stainless steel interception mesh, which is convenient for replacement and maintenance. It is highly practical.

[0016] 2. By setting a first support frame, this utility model facilitates the attachment of the handheld part of the air intake pipe to the ground, enabling directional vacuuming. This allows technicians to choose to hold the air intake pipe in their hand in any direction for vacuuming or place it on the first support frame, providing high flexibility.

[0017] 3. This utility model, by setting up a wet dust suppression mechanism, facilitates water mist spraying operations behind the dry dust collection mechanism, which can not only suppress and remove dust, but also cool down in hot weather. By setting up a rotating spray pipe and multi-head atomizing nozzles, it is easy to increase the spraying range and improve the dust removal efficiency.

[0018] 4. By setting a second support frame, this utility model can easily support the rotating nozzle in a backward direction, thus avoiding water mist spraying forward onto the air inlet pipe as much as possible.

The product has good performance.

[0026] like Figure 1 , Figure 2 and Figure 3As shown, the present invention includes a base plate 1, a dry dust collection mechanism and a wet dust suppression mechanism located on the upper part of the base plate 1, and a water baffle 16 and a mounting plate 18 are arranged sequentially above the base plate 1.

[0027] The dry dust collection mechanism includes a dust collection box 5, an air inlet pipe 7 disposed on one side of the dust collection box 5, and a fan 6 disposed on the other side of the dust collection box 5. The dust collection box 5 is placed on a base 4 located on the upper part of the base plate 1. The fan 6 is installed on the lower part of the baffle plate 16. One end of the base 4 is provided with a first support frame 10 in an inclined state. The hand handle 8 of the air inlet pipe 7 is detachably snapped into the first support frame 10.

[0028] The dust collection box 5 is provided with a dust collection bag 13. One end of the dust collection bag 13 is connected to the air inlet 11, and a filter box 31 is provided between the other end of the dust collection bag 13 and the exhaust port 12. The filter box 31 includes a stainless steel interception mesh 14 and an activated carbon adsorption mesh 15.

[0029] The wet dust suppression mechanism includes a water tank 20 mounted on the base 4, a high-pressure water pump 22 mounted on the baffle plate 16, and a rotary nozzle 25 mounted on the mounting plate 18. A water outlet pipe 21 connects the water tank 20 and the high-pressure water pump 22, and a water spray pipe 23 connects the high-pressure water pump 22 and the rotary nozzle 25. The other end of the rotary nozzle 25 is connected to a multi-head atomizing nozzle 26. A second support frame 27 for tilting the angle of the water spray pipe 23 is provided on the mounting plate 18.

[0030] In this embodiment, the lower part of the base plate 1 is provided with four universal wheels 2, one end of the base plate 1 is provided with a push rod 3, the base plate 1 is provided with four first support columns 17 for supporting the water baffle 16, and the water baffle 16 is provided with four second support columns 19 for supporting the mounting plate 18.

[0031] In actual use, the installation of casters 2 and push rods 3 makes it easy for technicians to move the device to a designated location on the construction site, or to move the device while vacuuming and spraying, providing high flexibility.

[0032] In actual use, by setting up a wet dust suppression mechanism, it is convenient to carry out water mist spraying operation behind the dry dust collection mechanism. It can not only suppress and remove dust, but also cool down in hot weather. By setting up a rotating spray pipe 25 and a multi-head atomizing nozzle 26, it is convenient to expand the spraying range and improve the dust removal efficiency.

[0033] In actual use, the dry dust collection mechanism facilitates the extraction of dust and other polluting gases from the air. The gases are then filtered through the stainless steel mesh 14 and activated carbon adsorption mesh 15 inside the dust collection box 5. The stainless steel mesh 14 intercepts large solid particles and collects them in the dust collection bag 13. The activated carbon adsorption mesh 15 is equipped with a composite adsorbent of modified activated carbon and molecular sieve, which facilitates the targeted purification of dusty gases. The purified gas is then discharged by the fan 6. At the same time, the dust collection bag 13 facilitates the collection of solid particles intercepted by the stainless steel mesh 14, making it easy to replace and maintain, and is highly practical.

[0034] In actual use, both the blower 6 and the high-pressure water pump 22 are connected to motors. The motors are located at the bottom of the baffle plate 16 to protect the motors from continuous water mist spraying. The water tank 20 is equipped with a screw cap to facilitate adding water to the water tank. The water outlet pipe 21 is connected to the bottom side of the water tank 20 to facilitate drawing clean water from the water tank 20.

[0035] It should be noted that the dust collection box 5 has a door panel on its side, with a handle on the door panel. The side of the door panel is hinged to the side of the dust collection box 5. The dust collection box 5 is made of iron. The filter box 31 has a magnet on the side near the activated carbon adsorption mesh 15, which allows it to be magnetically attached to the exhaust port 12 of the dust collection box 5. Technicians can remove the filter box 31 and then push out the stainless steel intercepting mesh 14 and the activated carbon adsorption mesh 15 from the side opening for replacement. The side of the filter box 31 near the stainless steel intercepting mesh 14 has internal threads for easy connection to one end of the dust collection bag 13. The air inlet 11 of the dust collection box 5 also has internal threads for easy connection to the other end of the dust collection bag 13, thus facilitating the removal and replacement of the dust collection bag 13 when there is a lot of garbage.

[0036] In this embodiment, a water stop valve 24 is provided on the water spray pipe 23.

[0037] In this embodiment, a dust collection hood 9 is provided on the handheld part 8 of the air intake pipe 7.

[0038] In this embodiment, the first support frame 10 is a U-shaped elastic plastic bracket, and the first support frame 10 is tilted upward and away from the dust collection box 5.

[0039] In actual use, by setting up the dust collection hood 9, it is easy to expand the suction range. The air inlet pipe 7 is a flexible hose, and the length can be adjusted and selected. This makes it easy for technicians to hold the handheld part 8 of the air inlet pipe 7 and perform manual dust suction in any direction. It is also easy to attach the handheld part 8 of the air inlet pipe 7 to the first support frame 10 to achieve directional and continuous dust suction facing the ground, which is highly flexible.

[0040] like Figure 3As shown, in this embodiment, the second support frame 27 is a hinge support, the bottom of the hinge support is a flat plate 28, the top of the hinge support is an inclined plate 29, and the inclined plate 29 is provided with a binding strap 30 for fixing the water spray pipe 23.

[0041] In actual use, the tilting plate 29 is tilted upwards, which makes it easier to raise the spray angle of the rotating nozzle 25 and expand the water mist coverage. By setting the second support frame 27, the rotating nozzle 25 can be supported in a backward direction, which can minimize the water mist spraying forward onto the air inlet pipe 7. By setting the water baffle 16 on the upper part of the fan 6, the equipment can be protected from being wetted by a large amount of continuous water mist, reducing the risk of damage and achieving good results.

[0042] In practical use, the motor is turned on, and the technician holds the air intake pipe 7 or places the air intake pipe 7 on the first support frame 10 to perform dust suction in front. The fan 6 draws the dusty air from the air intake pipe 7 into the dust collection bag 13 and then through the filter box 31. The stainless steel intercepting mesh 14 in the filter box 31 intercepts large solid particles and collects them in the dust collection bag 13. The activated carbon adsorption mesh 15 in the filter box 31 specifically purifies the dusty gas, and then the purified gas is discharged by the fan 6 to achieve dry dust suction purification. At the same time, the high-pressure water pump 22 can draw clean water from the water tank 20 and spray it on a large area at the rear through the rotating spray pipe 25 and the multi-head atomizing nozzle 26 to achieve wet spray purification, thereby achieving a dual air purification effect. Moreover, the two are in different directions, and the sprayed water mist is difficult to be drawn into the air intake pipe 7, ensuring the safe and effective operation of the equipment.

[0043] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
