Technical Field

[0001] This utility model belongs to the field of dust removal tools for construction, and specifically relates to a portable dust removal device for construction. Background Technology

[0002] Construction sites, waste recycling plants, and dump trucks all generate significant amounts of dust during operation, leading to air pollution, increasing PM2.5 and PM10 concentrations, and affecting human respiratory health. Therefore, dust control measures are necessary for locations and equipment prone to dust generation. Construction dust pollution refers to the pollution of the atmosphere caused by particulate matter generated during production activities such as building construction, road and pipeline construction, building demolition, material transportation, material storage, road cleaning, and exposed soil. Materials that easily generate dust pollution at construction sites mainly include: sand, gravel, ash, plaster, construction waste, and engineering spoil.

[0003] Construction work typically requires dust removal at construction sites. Existing dust removal devices usually use atomizing nozzles for spraying, but atomizing nozzles are usually fixed in place, limiting the coverage area of ​​the spray. Utility Model Content

[0004] The purpose of this invention is to provide a portable dust removal device for construction sites that can achieve rotating spraying without the need for external rotational power, effectively expanding the coverage area of ​​spray dust removal.

[0005] A portable dust suppression device for construction includes: a damping tank, a return baffle, a rotary joint, a rotating pipe, an atomizing nozzle, a power pipe, a return water pipe, an inlet water pipe, and a water tank. The damping tank has an opening at the top and a central hole and a drain hole at the center. The return baffle is an annular plate connected to the middle of the damping tank, with the central hole and drain hole located inside the return baffle. The rotary joint is connected to the central hole. The rotating pipe is an L-shaped pipe, with its lower part connected to the top of the rotary joint. The atomizing nozzle is connected to the front of the rotating pipe. The top of the power pipe is connected to the side wall of the rotating pipe, and its lower part is located between the damping tank and the return baffle. The water tank is located at the bottom of the damping tank. The top of the return water pipe is connected to the bottom of the drain hole, and the top of the inlet water pipe is connected to the bottom of the rotary joint. The bottom of the return water pipe is located inside the water tank. A water pump is installed inside the water tank, and the bottom of the inlet water pipe extends into the water tank and connects to the outlet of the water pump. A support frame connects the damping tank and the water tank.

[0006] Furthermore, the damping tank and the return baffle form an annular groove, and the lower outlet of the power pipe is inclined in the tangential direction of the annular groove. The height of the damping tank is greater than the height of the return baffle.

[0007] Furthermore, the rotary joint includes: an upper annular column, a lower annular column, an upper connecting pipe, a lower connecting pipe, a central pipe, retaining rings, and a bearing. The upper annular column is provided with a first through hole, and the upper connecting pipe is connected to the top of the upper annular column; the lower annular column is provided with a second through hole, and the lower connecting pipe is connected to the bottom of the lower annular column; the central pipe is fitted into the first and second through holes, and retaining grooves are provided on the outer walls of the upper and lower ends of the central pipe, with two retaining rings installed in the two retaining grooves respectively; the bearing is fitted onto the outside of the central pipe and is installed between the upper and lower annular columns; the upper connecting pipe is connected to the lower part of the rotary pipe, and the lower annular column is connected to the central hole.

[0008] Furthermore, sealing rings are provided between the retaining ring and the upper annular post, as well as between the retaining ring and the lower annular post.

[0009] Furthermore, a water inlet is provided on the top of the water tank, the bottom of the return water pipe is connected to the top of the water tank, and the bottom of the water inlet pipe passes through the water tank and connects to the outlet of the water pump.

[0010] Furthermore, the water tank has an open-top structure.

[0011] Furthermore, the bottom of the power pipe is sealed, and multiple water spray holes are provided on one side, with the water spray holes facing the tangential direction of the annular groove.

[0012] This utility model has the following advantages compared with the prior art:

[0013] This invention effectively expands the coverage area of ​​spray dust suppression through its structural design. Water is supplied by a water pump, and after passing through a rotary joint, the water is sprayed outwards via a rotating pipe and atomizing nozzles, thus suppressing dust at construction sites and indoor work areas through water mist. Simultaneously, a portion of the water flow is diverted through a power pipe into a damping tank. The outlet of the power pipe faces tangentially. When a portion of water accumulates in the damping tank, the water flow further increases the reaction force on the power pipe, causing it to rotate the rotating pipe, thereby achieving the rotating spray from the atomizing nozzles. Once the damping tank's return baffle is full, the water overflows through the baffle into the center of the damping tank, and then re-enters the water tank through a return pipe. This achieves rotating spraying without the need for external rotational power, increasing the spray coverage area. Attached Figure Description

Figure 3 As shown, is Figure 2 Sectional view along the BB direction.

[0022] A portable dust removal device for construction sites includes: a damping tank 1, a return baffle 2, a rotary joint 3, a rotating pipe 4, an atomizing nozzle 5, a power pipe 6, a return water pipe 7, a water supply pipe 8, and a water tank 9. The damping tank 1 has an opening at the top and a central hole and a drain hole at the center. The return baffle 2 is an annular plate connected to the middle of the damping tank 1, with the central hole and drain hole located inside the return baffle 2. The rotary joint 3 is connected to the central hole, and the rotating pipe 4 is an L-shaped pipe connected to the rotary joint 3 at its lower part. At the top, the atomizing nozzle 5 is connected to the front of the rotating tube 4; the top of the power tube 6 is connected to the side wall of the rotating tube 4, and the lower part of the power tube 6 is located between the damping pool 1 and the return baffle 2; the water tank 9 is located at the bottom of the damping pool 1, the top of the return water pipe 7 is connected to the drain hole, the top of the water supply pipe 8 is connected to the bottom of the rotary joint 3, and the bottom of the return water pipe 7 is connected to the top of the bottom of the water tank 9; a water pump 91 is installed inside the water tank 9, and the bottom of the water supply pipe 8 passes through the water tank 9 and connects to the outlet of the water pump 91.

[0023] The damping tank 1 and the return baffle 2 form an annular groove, and the lower outlet of the power pipe 6 is inclined towards the tangent of the annular groove. The height of the damping tank 1 is greater than the height of the return baffle 2.

[0024] In this invention, a bracket 11 is connected between the damping pool 1 and the water tank 9 to achieve connection between the water tank 9 and the damping pool 1.

[0025] Alternatively, the bottom of the power pipe 6 can be sealed, and multiple water spray holes can be set on one side, with the water spray holes facing the tangent direction of the annular groove.

[0026] like Figure 4 The figure shown is a cross-sectional structural diagram of the rotary joint 3 in this utility model.

[0027] The rotary joint 3 includes: an upper annular column 31, a lower annular column 32, an upper connecting pipe 33, a lower connecting pipe 34, a central pipe 35, retaining rings 36, and a bearing 37. The upper annular column 31 has a first through hole, and the upper connecting pipe 33 is connected to the top of the upper annular column 31. The lower annular column 32 has a second through hole, and the lower connecting pipe 34 is connected to the bottom of the lower annular column 32. The central pipe 35 is fitted into the first and second through holes, and retaining grooves are provided on the outer walls of the upper and lower ends of the central pipe 35, with two retaining rings 36 installed in the two retaining grooves. The bearing 37 is fitted onto the outside of the central pipe 35 and is installed between the upper annular column 31 and the lower annular column 32. The upper connecting pipe 33 is connected to the lower part of the rotary pipe 4, and the lower annular column 32 is connected to the central hole.

[0028] Sealing rings are provided between the retaining ring 36 and the upper annular post 31, and between the retaining ring 36 and the lower annular post 32.

[0029] Water is added to the water tank 9, and water is supplied to the atomizing nozzle 5 by the water pump 91. The water discharged from the return pipe 7 flows back into the water tank 9.

[0030] The water tank 9 has an open top structure. A water inlet 92 can also be provided on the top of the water tank 9 to facilitate observation of the water level in the water tank 9 and cleaning of the water tank 9. The return water pipe 7 only needs to be above the water tank 9 for convenient return flow.

[0031] In this invention, the water outlet damping of the power pipe 6 is greater than or equal to the water outlet damping of the atomizing nozzle 5, thus limiting the water flow distributed by the power pipe 6 and not hindering the spraying of the atomizing nozzle 5.

[0032] By connecting the water pump 91 to its compatible power supply via wires, a suitable controller can be selected to meet the control requirements.

[0033] In use, water is supplied to the atomizing nozzle 5 by the water pump 91. The water passes through the rotary joint 3, then through the rotating pipe 4 and the atomizing nozzle 5, and is sprayed outward. The water mist is used to spray water and remove dust at the construction site / indoor construction site. At the same time, a portion of the water flow is diverted through the power pipe 6 and discharged into the damping tank 1. When a portion of water is stored in the damping tank 1, the water flow acts on the water in the damping tank 1 to further increase the reaction force on the power pipe 6, causing the power pipe 6 to drive the rotating pipe 4 to rotate, thereby realizing the rotating spray of the atomizing nozzle 5. After the annular groove between the damping tank 1 and the return baffle 2 is filled with water, the water overflows into the damping tank 1 through the return baffle 2 and is reinjected into the water tank 9 through the return water pipe 7.

[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, the phrase "comprising an element defined as..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0035] The terminology used in this invention is descriptive and exemplary, and not restrictive. Since this invention can be embodied in various forms without departing from the spirit or essence of the technical solution, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims.
