Description

A construction dust suppression device Technical Field

[0001] This application relates to the field of dust suppression technology, and in particular to a construction dust suppression device. Background Technology

[0002] Construction sites often generate a lot of dust, which can easily spread with the air and cause dust storms, affecting the health of construction workers and polluting the surrounding environment.

[0003] To reduce dust pollution at construction sites, dust suppression devices are typically installed. These devices humidify the dust, thereby reducing the amount of suspended dust particles in the air at the construction site.

[0004] Existing dust suppression systems typically involve laying dust suppression pipelines at the locations within the construction site where dust control is required. High-pressure water flows through these pipelines, which are also equipped with atomizing nozzles connected to the pipeline interior. When dust is being suppressed at the construction site, the atomizing nozzles spray the high-pressure water from the pipeline into atomized form. The atomized water mixes with suspended dust particles in the air, and these particles, under their own gravity, fall to the ground, thus reducing the dust concentration in the air.

[0005] However, existing atomizing nozzles are generally fixedly installed on pipelines, making it difficult to change the spray direction of the atomizing nozzles. At the same time, it is difficult to increase the number of atomizing nozzles after the management and deployment are completed. Summary of the Invention

[0006] To facilitate adjustment of the spray direction of the atomizing nozzles and to increase the number of atomizing nozzles, this application provides a construction dust suppression device.

[0012] Atomizing nozzle is sealed at the opening;

[0013] A sealing seat is installed at the end of the liquid guide tube away from the mounting base;

[0014] The number of atomizing nozzles can be changed by splicing different numbers of the liquid guiding tubes, and the spray angle of the atomizing nozzles can be changed by making the liquid guiding tubes rotate around the axis of the corresponding mounting holes.

[0015] Optionally, one end of the liquid guiding tube is equipped with a plurality of positioning blocks, and the other end of the liquid guiding tube is provided with a plurality of positioning grooves corresponding to the positioning blocks, wherein the positioning blocks and the positioning grooves are inserted into each other.

[0032] The present application will be further described in detail below with reference to Figures 1-5.

[0033] This application discloses a construction dust suppression device.

[0034] A construction dust suppression device includes a water pipe 1, a mounting base 2, a liquid guiding cylinder 3, an atomizing nozzle 4, and a sealing seat 5. The mounting base 2 is fixedly mounted on the water pipe 1, the liquid guiding cylinder 3 is mounted on the mounting base 2, the atomizing nozzle 4 is mounted on the liquid guiding cylinder 3, and the water pipe 1, mounting base 2, liquid guiding cylinder 3, and atomizing nozzle 4 are interconnected. The sealing seat 5 is mounted on the end of the liquid guiding cylinder 3 away from the mounting base 2.

[0035] High-pressure water flows through water pipe 1, passing through mounting base 2, liquid guide tube 3, and atomizing nozzle 4 in sequence. The high-pressure water is then atomized and sprayed out from the atomizing nozzle 4. To add different numbers of atomizing nozzles 4, several liquid guide tubes 3 are selected and connected end-to-end. The atomizing nozzles 4 are then installed on the corresponding liquid guide tubes 3. To adjust the spray direction of the atomizing nozzles 4, the angle between adjacent liquid guide tubes 3 is adjusted during installation.

[0036] Mounting base 2 is T-shaped and has an internal cavity. Mounting holes 21 are formed on the cavity wall and are located at the end of mounting base 2. Mounting tube is integrally formed on mounting base 2. A connecting hole is formed on the wall of water pipe 1. The mounting tube and the connecting hole are threaded together, and water inside water pipe 1 enters the cavity of mounting base 2 through the mounting tube.

[0037] The liquid guiding cylinder 3 is cylindrical in shape, and a number of positioning blocks 34 are integrally formed at one end of the liquid guiding cylinder 3. The positioning blocks 34 are evenly distributed circumferentially along the axis of the liquid guiding cylinder 3. A limit block 35 is integrally formed on the side wall of each positioning block 34, and the positioning blocks 34 and the limit blocks 35 are arranged in an L-shape.

[0038] The other end of the liquid guide tube 3 is provided with a number of positioning grooves 32 corresponding to a number of positioning blocks 34. Each positioning groove 32 has a limit groove 33 on its side wall. The positioning grooves 32 and the limit grooves 33 are arranged in an L-shape.

[0039] The positioning block 34 and the corresponding positioning groove 32 are inserted into each other, and the limiting block 35 and the corresponding limiting groove 33 are slidably engaged. When splicing two adjacent liquid guiding cylinders 3, the two liquid guiding cylinders 3 are placed along their length. Then, the positioning block 34 is inserted into the positioning groove 32, and the liquid guiding cylinder 3 is rotated, causing the limiting groove 33 to slide inside the limiting groove 33. The groove wall of the limiting groove 33 limits the liquid guiding cylinder 3 through the limiting block 35.

[0040] To improve the ease of rotation of the liquid guide cylinder 3, several levers 38 are integrally formed on the side wall of the liquid guide cylinder 3. The levers 38 are circumferentially distributed along the axis of the liquid guide cylinder 3, and the length direction of the levers 38 is consistent with the length direction of the liquid guide cylinder 3. The operator can rotate the two liquid guide cylinders 3 relative to each other by using the levers 38, which increases the friction between the operator and the levers 38.

[0041] To facilitate the determination of the rotation angle between two adjacent liquid guide cylinders 3, a scale mark can be provided circumferentially along the axis of the liquid guide cylinder 3 at the end of the outer peripheral surface of the liquid guide cylinder 3 near the positioning block 34, and an indicator mark can be provided at the end of the outer peripheral surface of the liquid guide cylinder 3 near the positioning groove 32. When the two liquid guide cylinders 3 are rotated relative to each other, the operator refers to the indicator mark and the scale mark to determine the rotation angle between the two adjacent liquid guide cylinders 3.

[0042] To reduce the possibility that the limiting block 35 may slide out of the limiting groove 33 due to accidental contact of the liquid guide tube 3, a blocking block 6 is detachably installed at the positioning groove 32. The blocking block 6 is detachably fixed to the inner wall of the positioning groove 32 by screws.

[0043] After the limiting block 35 slides into the limiting groove 33, the blocking block 6 is detachably fixed to the positioning groove 32 by screws. The blocking block 6 limits the positioning block 34, thereby improving the installation stability of the two adjacent liquid guiding cylinders 3.

[0044] To improve the accuracy of the blocking block 6 in the positioning groove 32, a groove 36 is provided on the side wall of the positioning groove 32. A protrusion 61 is integrally formed on the side wall of the blocking block 6 corresponding to the groove 36, and the protrusion 61 and the groove 36 slide in engagement. To facilitate the removal of the blocking block 6, a lever 62 is also fixedly installed on the blocking block 6.

[0045] To further improve the sealing between two adjacent liquid guide cylinders 3, annular sealing grooves 37 are provided at both ends of the liquid guide cylinder 3, and annular sealing gaskets are embedded in the sealing grooves 37.

[0046] An opening 31 is provided on the wall of the liquid guiding cylinder 3, and the atomizing nozzle 4 is threadedly connected to the opening 31 of the liquid guiding cylinder 3, thereby improving the convenience of installing the atomizing nozzle 4.

[0047] To facilitate the installation of the liquid guide tube 3 on the mounting base 2, the mounting base 2 is provided with corresponding positioning grooves 32 and limiting grooves 33 near the mounting hole 21, and corresponding blocking blocks 6 can be detachably and fixedly installed at the positioning grooves 32 on the mounting base 2.

[0048] The sealing seat 5 includes an integrally formed sealing plate 51 and sealing blocks 52. Several sealing blocks 52 are provided, and the several sealing blocks 52 are evenly distributed circumferentially along the axial direction of the sealing plate 51. The several sealing blocks 52 correspond to several positioning grooves 32, and the sealing blocks 52 and the corresponding positioning grooves 32 are inserted into each other.

[0049] The sealing seat 5 is installed at the end of the liquid guide tube away from the mounting seat 2. When installing the sealing seat 5, the sealing block 52 is inserted into the corresponding positioning groove 32 and the sealing plate 51 and the sealing ring are made to abut against each other. Then, the sealing block 52 is fixedly installed in the positioning groove 32 by screws.

[0050] The sealing seat 5 can also be installed on the mounting seat 2 to seal the mounting seat 2.

[0051] The implementation principle of a construction dust suppression device according to an embodiment of this application is as follows: A mounting base 2 is installed on a water pipe 1, a liquid guide pipe is installed on the mounting base 2, an atomizing nozzle 4 is installed on the liquid guide pipe, and a sealing seat 5 is installed at the end of the liquid guide pipe away from the mounting base 2. When installing the mounting base 2 on the water pipe 1, the mounting pipe and the connecting hole on the mounting base 2 are threaded together. When installing two adjacent liquid guide pipes, the positioning block 34 on the liquid guide pipe is inserted into the corresponding positioning groove 32, and the liquid guide pipe is rotated so that the limiting block 35 slides into the limiting groove 33. Then, the blocking block 6 is installed in the positioning groove 32 with screws, and the positioning block 34 is limited by the screws. Finally, the atomizing nozzle 4 is threadedly connected to the opening 31 of the liquid guide pipe. When sealing the liquid guide tube, insert the sealing block 52 into the corresponding positioning groove 32 and make the sealing plate 51 and the sealing ring abut against each other. Then, fix the sealing block 52 in the positioning groove 32 with screws. This makes it easier to adjust the spray direction of the atomizing nozzle 4 and increase the number of atomizing nozzles 4.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
