Description

Technical Field

[0001] The utility model relates to the technical field of spray dust suppression, and particularly to a portable replaceable nozzle assembly. Background Art

[0002] In mining engineering, a large amount of dust will be generated during the processes of mining, transportation, etc. It not only affects production operations, pollutes the environment, but also poses a hazard to the physical health of workers and is likely to cause respiratory diseases. Therefore, at present, spray dust suppression systems are used in mines to suppress dust. In order to increase the coverage area of the spray, multiple nozzle assemblies are often connected in series on the pipeline. However, the existing nozzle assemblies and pipelines are usually connected by thread fitting, which is not only very time-consuming and laborious during assembly, but also inconvenient to disassemble during maintenance and replacement. Content of the Utility Model

[0003] In order to solve the technical problems existing in the above background art, the utility model provides a portable replaceable nozzle assembly.

[0004] The technical solution of the utility model is as follows:

[0005] A portable replaceable nozzle assembly is used for connecting in a pipeline system for spraying. It includes a main body, on which there are two through holes respectively for connecting a water pipe and an air pipe, and the main body is also provided with an air-water mixing nozzle communicated with the two holes;

[0006] At the positions near the two ends of the two holes of the main body, there are clamping holes, and clamping columns are inserted into the clamping holes, and part of the clamping columns extends into the holes;

[0007] The nozzle assembly has two usage states:

[0008] When the nozzle assembly is connected in the middle of the pipeline system, pipeline connectors are inserted at both ends of the two holes, and a first clamping platform is arranged on the side surface of the pipeline connector, which is clamped with the part of the clamping column extending into the hole;

[0009] When the nozzle assembly is connected at the end of the pipeline system, a pipeline connector is inserted into one end of the two holes, and a plug is inserted into the other end. A second clamping platform is arranged on the side surface of the plug, which is clamped with the part of the clamping column extending into the hole.

[0010] Preferably, a pair of clamping holes are arranged at each port of the hole, symmetrically arranged on both sides of the center line of the hole, so as to stably lock the pipeline connector and the plug on the main body.

[0011] Specifically, the two holes extend left and right and are arranged front and back. The two clamping holes in each pair are arranged front and back and extend vertically.

[0012] Among them, the maximum distance between the inner sides of the two snap holes in each pair is greater than the aperture of the corresponding duct, and the center distance is less than the aperture of the corresponding duct. The two snap holes are symmetrically located on both sides of the pipe connector or the plugging head. Without occupying too much space in the duct, more parts of the snap post are exposed in the duct to block the first snap table or the second snap table.

[0013] Preferably, the snap hole is a through hole to facilitate the insertion and removal of the snap post.

[0014] In order to increase the air-water mixing ratio so that there is more air and greater air pressure to improve the atomization effect of water, the aperture of the duct connecting the air pipe is larger than the aperture of the duct connecting the water pipe.

[0015] In this application, the duct is in a dumbbell shape, and the first snap table and / or the second snap table abut against the inner end faces of the holes at both ends of the duct, preventing the pipe connector and the plugging head from being inserted too deep or too shallow without any restriction when inserted into the duct, which is not conducive to the snap connection between the first snap table and / or the second snap table and the snap post.

[0016] The main body of this application is preferably in the shape of a rectangular body. Two ducts penetrate the left and right sides of the main body, the snap holes penetrate the upper and lower sides of the main body, and the air-water mixing nozzle is arranged on the lower side of the main body.

[0017] Among them, a connection hole extending vertically downward is provided on the main body for connecting the air-water mixing nozzle. The connection hole is located between the two ducts and close to the duct connecting the water pipe. Its side wall is communicated with the side wall of this duct, and the bottom is communicated with the top of the side wall of the duct connecting the air connection hole through a communication hole.

[0018] In order to install the main body, an installation part is also provided on the top surface of the main body, which extends upward. The extended end is provided with an installation portion, and the installation portion is inclined at an angle of 45 degrees with the vertical plane, enabling the air-water mixing nozzle to spray obliquely at an angle of 45 degrees, so that the nozzle can spray farther and have a larger coverage range.

[0019] A portable replaceable nozzle assembly provided by the utility model is provided with snap holes on the main body, snap tables on the pipe connector and the plugging head, snap posts are inserted into the snap holes, and part of the snap posts extends into the duct and cooperates with the snap tables for snap connection. The pipe connector and the plugging head are locked on the main body through the snap posts. Whether it is for installation or replacement of the nozzle assembly, by inserting and removing the snap posts, the locking and unlocking of the pipe connector and / or the plugging head can be achieved. The operation is simple, and it is convenient and fast to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] As Figure 1 shown, the embodiment of the present utility model provides a portable replaceable spray head assembly, which is used to be connected in a pipeline system for spraying. Multiple spray head assemblies of the present application can be connected in series in the pipeline system, and the spray head assemblies are connected by pipes. In order to achieve the series connection of the spray head assemblies and the quick connection between the spray head assembly and the pipe, the spray head assembly of the present application includes a main body 1, on which there are two channels 11 respectively used for connecting a water pipe and an air pipe and penetrating through the main body 1. The main body 1 is also provided with an air-water mixing nozzle 2 communicated with the two channels 11, which is used to mix the air and water in the two channels 11 in the nozzle and spray the water in a mist shape.

[0027] Clamping holes 12 are provided at positions near the two ends of the two channels 11 of the main body 1, and clamping posts 3 are inserted into the clamping holes 12, and a part of the clamping posts 3 extends into the channels 11.

[0028] The spray head assembly has two usage states corresponding to its connection position in the pipeline system:

[0029] In one case, when the spray head assembly is connected in the middle of the pipeline system, pipe connectors 4 are inserted into both ends of the two channels 11. One end of the pipe connector 4 is inserted into the channel 11, and the other end is fixedly connected to the pipe. The other end of the pipe can be connected to another spray head assembly through the pipe connector 4 again, so as to complete the series connection of multiple spray head assemblies. A first clamping platform 41 is provided on the side surface of the pipe connector 4, which is clamped with the part of the clamping post 3 extending into the channel 11. Through the clamping of the clamping post 3 and the first clamping platform 41, the pipe connector 4 is locked on the main body 1, realizing the quick connection between the spray head assembly and the pipe.

[0030] Another case is when the nozzle assembly is connected to the end of the pipeline system. Since there is no need to continue connecting another nozzle assembly in series, one end of each of the two channels 11 is internally inserted with a pipeline connector 4, and the other end is inserted with a plug 5 to seal the channel 11. Similarly to the pipeline connector 4, a second clamping platform 51 is provided on the side of the plug 5 and is clamped with the part of the clamping post 3 extending into the channel 11.

[0031] When connecting the pipeline to the nozzle assembly of the present application, the pipeline connector 4 is directly inserted into the channel 11, the clamping post 3 is inserted into the clamping hole 12, the clamping post 3 extends into the channel 11 and is clamped outside the first clamping platform 41, clamping the first clamping platform 41, so that the pipeline connector 4 cannot be pulled out of the main body 1, realizing the quick connection of the pipeline and the main body 1, and the connection is firm and not easy to be disengaged. When replacement is needed, the clamping post 3 is pulled out, and then the pipeline connector 4 can be pulled out, which is convenient for replacement.

[0032] It should be noted here that for the convenience of comprehensively showing all the components of the nozzle assembly, the Figure 1 figure shows the structure when it is located at the end of the pipeline system, but those skilled in the art should be able to know the structural style of the nozzle assembly when it is located in the middle of the pipeline system without any difficulty. Figure 1

[0033] More specifically, a pair of clamping holes 12 are provided at each port of the channel 11, symmetrically arranged on both sides of the center line of the channel 11, so as to stably lock the pipeline connector 4 and the plug 5 on the main body 1.

[0034] The specific positional relationship between the clamping holes 12 and the channel 11 is that the two channels 11 extend left and right and are arranged front and back, and the two clamping holes 12 in each pair are arranged front and back and extend vertically.

[0035] Among them, the maximum distance between the inner sides of the two clamping holes 12 in each pair is greater than the aperture of the corresponding channel 11, but the center distance is less than the aperture of the corresponding channel 11, so that the two clamping holes 12 are symmetrically located on both sides of the pipeline connector 4 or the plug 5, and a part of the side is clamped with the clamping platform, and the other part is still located in the clamping hole 12, improving the supporting force of the clamping hole 12 on the clamping post 3, thereby improving the clamping stability of the clamping post 3. In addition, it can also make more parts of the clamping post 3 exposed in the channel 11 without occupying too much space in the channel 11, so as to block the first clamping platform 41 or the second clamping platform 51.

[0036] ​The snap - fit hole 12 is preferably a through - hole for facilitating the insertion and removal of the snap - fit post 3. Additionally, when the snap - fit post 3 is inserted into the snap - fit hole 12, both ends of it are located within the snap - fit hole 12, and the middle part is exposed in the duct 11 and is snap - fitted with the snap - fit platform. In this way, both ends of the snap - fit post 3 are fixed by the snap - fit hole 12, and a blocking force to prevent the pipe connector 4 from being pulled out is provided by both ends of the snap - fit post 3, enabling the snap - fit post 3 to withstand greater forces. When the pipe connector 4 is subjected to a large pulling force, it is not easily disengaged from the snap - fit post 3, thereby making the snap - fit stability between the snap - fit post 3 and the snap - fit platform higher.

[0037] As Figure 2 shown, in this embodiment, the duct 11 is in a dumbbell shape, and the first snap - fit platform 41 and the second snap - fit platform 51 are abutted against the inner end faces of the two ends of the duct 11, preventing the pipe connector and the plug 5 from being inserted too deeply or too shallowly in the duct 11 without any restriction when inserted, which is not conducive to the docking between the first snap - fit platform 41 and the second snap - fit platform 51 and the snap - fit post 3.

[0038] Another Figure 1 and Figure 3 shown, the main body 1 of this embodiment is preferably in the shape of a rectangular body. Two ducts 11 penetrate the left and right sides of the main body 1, the snap - fit holes 12 penetrate the upper and lower sides of the main body 1, and the air - water mixing nozzle 2 is arranged on the lower side of the main body 1.

[0039] Among them, the aperture of the duct 11 for connecting the air pipe is larger than the aperture of the duct 11 for connecting the water pipe, so that in the air - water ratio introduced into the main body 1, the proportion of air is larger, in order to have more air and greater air pressure to improve the atomization effect of water.

[0040] In addition, the main body 1 is provided with a connection hole 13 that opens downward and extends vertically for connecting the air - water mixing nozzle 2. The connection hole 13 is located between the two ducts 11 and is close to the duct 11 for connecting the water pipe. When processing the connection hole 13, its side wall can be directly communicated with the side wall of the duct 11 for connecting the water pipe, and the bottom of the connection hole 13 is communicated with the top of the side wall of the duct 11 for connecting the air hole through the communication hole 14.

[0041] In this embodiment, the air - water mixing nozzle 2 includes a core 21. The bottom end of the core 21 extends into the connection hole 13, and a sealing ring is arranged on the outer side of the end to separate it from the water - passing duct 11 and the communication hole 14. An air passage is provided in the core 21, and the air introduced into the duct 11 is ejected from the nozzle head through the communication hole 14 - the air passage of the core 21. A water channel is formed between the outer side wall of the core 21 and the inner side wall of the connection hole 13. The water introduced into the other duct 11 enters the connection hole 13 and flows towards the nozzle head, mixes with the air, and is atomized by the air and ejected. This method can greatly save water consumption.

[0042] To install the main body 1, an installation member 6 is further provided on the top surface of the main body 1. The installation member 6 extends upward, and an installation portion 61 is provided at the extended end. The installation portion 61 is inclined at an angle of 45 degrees with respect to the vertical plane, so that the air-water mixing nozzle 2 can spray obliquely at an angle of 45 degrees, thereby enabling the nozzle to spray farther and covering a larger range.

[0043] In this embodiment, the installation member 6 is detachably connected to the main body 1.
