Description

Technical Field

[0001] The invention relates to the technical field of ore machinery, in particular to an environmentally friendly dust reduction device for mine quarrying construction. Background Art

[0002] During the mine construction process, dust suppression devices are indispensable equipment to ensure a clean working environment, maintain the health of workers, and comply with environmental protection laws and regulations. With the enhancement of environmental awareness and increasingly stringent regulations, dust control in mine construction has become a vital task. Dust will not only cause harm to the respiratory system of workers, but may also cause a series of occupational diseases. At the same time, it will also pollute the surrounding environment and affect the ecological balance. Therefore, the use of effective dust suppression devices is crucial to ensure the sustainability of mine construction. At present, the more popular dust suppression devices on the market mainly include high-pressure spray dust suppression devices and fog cannons. High-pressure spray dust suppression devices use high-pressure pumps to transport water to the fog spray nozzles through pipelines, and use spray to moisten and settle dust particles in the air, thereby effectively reducing the dust concentration in the air. The fog cannon plays an important role in large-scale mine construction with its powerful range and wide coverage. It atomizes water through high pressure and sprays it over a long distance, effectively suppressing the spread of dust.

[0003] In the process of implementing the present invention, the inventors found that there are at least the following problems in the prior art: Although high-pressure spray dust suppression devices and fog cannons have been widely used in mine construction, they each have some technical defects. The high-pressure spray dust suppression device is limited by the layout of the pipeline, and its range is relatively short, and it cannot cover the area far away from the nozzle, resulting in the dust suppression effect may not be ideal in some large or open construction sites. In addition, the laying and maintenance of pipelines also increase the construction cost and complexity. Although the fog cannon has a long range and a wide coverage, its spray direction is relatively single. Although it is equipped with a rotation system, it still cannot achieve all-round coverage without dead ends. This means that in some complex terrains or areas requiring fine dust suppression, the effect of the fog cannon may be limited.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] See also Figure 2-5 The present invention provides a technical solution: a dust suppression device for environmental protection in mining and quarrying construction, comprising a wind tube 100 erected in a vertical direction, a water ring 200 fixedly erected on the top of the wind tube 100, and a water pump 300 erected outside the wind tube 100 for supplying water to the water ring 200, the water ring 200 is composed of an annular tube 210 and a plurality of nozzle assemblies 220 assembled on the annular tube 210 in an annular array, the wind tube 100 comprises a cylinder shell 110 and a coaxial flange assembled on the cylinder shell 110. 10, a net cylinder 120 is supported at the top thereof, and a cover plate 140 is erected on the top of the cylinder shell 110 through a plurality of partitions 130, a fan 150 is fixedly installed in the cylinder shell 110, a conical bucket 160 is coaxially welded to the bottom of the cover plate 140, a plurality of partitions 130 are distributed in an annular array and welded on the outer wall of the conical bucket 160 to form an air duct between any two adjacent partitions 130, and a plurality of nozzle assemblies 220 correspond to the plurality of air ducts one by one.

[0017] Based on the above-mentioned structural setting, the environmentally friendly dust suppression device for mining and quarrying construction is composed of a wind tube 100, a water ring 200 and a water pump 300, wherein the water ring 200 is mounted on the top of the wind tube 100, and can cooperate with the air outlet opened on the circumference of the top of the wind tube 100 to form a local full-angle dust suppression coverage, and the water pump 300 is used to supply water to the water ring 200. Specifically, during the working process, when the dust suppression device needs to be started, after the water pump 300 is started, water is transported to the water ring 200, and output by the nozzle assembly 220 to form fine water mist particles. At the same time, after the fan 150 in the wind tube 100 is started, wind flow is generated, and the wind flow passes through the air duct formed between the partitions 130, and is blown upward from the bottom of the conical bucket 160 to separate the water mist particles. After meeting, the water mist particles can quickly diffuse outward under the action of wind force, achieving local full-angle dust reduction coverage. The airflow generated by the fan 150 not only helps to diffuse the water mist particles to a farther distance, but also can draw the dust particles in the air into the water mist, making them moist and settled. The environmentally friendly dust reduction device for mine quarrying construction, by providing a wind tube 100 erected in a vertical direction and a water ring 200 fixedly mounted on the top of the wind tube 100, and a ring array layout of the nozzle assembly 220, can achieve local full-angle dust reduction coverage of the mine construction area, overcome the defects of limited range of high-pressure spray dust reduction devices and single spray direction of fog cannons, and ensure that the ideal dust reduction effect can be achieved in different terrains and complex environments.

[0018] For further information, see Figure 5 , Figure 7 and Figure 8 The annular tube 210 is composed of a plurality of pipe sections 2110 distributed in a circular array and fixedly mounted on the side of the cover plate 140, and a space for the nozzle assembly 220 to be rotated and assembled is reserved between any two adjacent pipe sections 2110. It also includes an adjustment mechanism 400 for synchronous movement of the plurality of nozzle assemblies 220. The adjustment mechanism 400 includes a screw rod 410 rotatably mounted on the cover plate 140 through a bearing in a vertical direction and a movable sleeve 420 threadedly mounted on the screw rod 410, and a handwheel 430 fixedly mounted on the top of the screw rod 410. The outer wall of the movable sleeve 420 is provided with a plurality of hinge seats 440 corresponding to the plurality of nozzle assemblies 220 one by one, and the outer sides of the plurality of hinge seats 440 are hinged with connecting rods 450, and the tops of the plurality of nozzle assemblies 220 are provided with slide grooves 460 for movable connection of the bottom ends of the connecting rods 450. Among them, the adjustment mechanism 400 realizes precise adjustment of the nozzle assembly 220 through components such as the screw 410, the movable sleeve 420 and the connecting rod 450. The construction personnel can manually adjust the position of the movable sleeve 420 according to the construction environment and needs, thereby synchronously changing the spraying angle and height of all nozzle assemblies 220. This design enables the dust reduction device to adapt to the dust reduction needs in different terrains and complex environments.

[0019] For further information, see Figure 5 and Figure 6 , both ends of several pipe sections 2110 are provided with threaded ports 2120, the nozzle assembly 220 includes a connecting pipe 2210 and a first atomizing nozzle 2220 vertically arranged in the middle of the connecting pipe 2210, both ends of the connecting pipe 2210 are embedded and adapted with the threaded ports 2120 and are sleeved with a plurality of O-rings 2230 on the outside, and both ends of the connecting pipe 2210 are sleeved with threaded caps 2240 that can be locked and connected with the threaded ports 2120. Among them, the design of the connecting pipe 2210 allows the nozzle assembly 220 to rotate at a certain angle to adapt to different construction environments and dust reduction requirements. Construction personnel can flexibly adjust the spray angle of the nozzle assembly 220 according to actual conditions to ensure the maximization of the dust reduction effect. Both ends of the connecting pipe 2210 are embedded and adapted to the threaded port 2120, and a tight sealing connection is achieved through the O-ring 2230 and the threaded cap 2240. This design can effectively prevent water from leaking from the connection to ensure the normal operation and dust reduction effect of the dust reduction device. The O-ring 2230, as a sealing element, has good elasticity and wear resistance. It can adapt to the tiny gap between the connecting pipe 2210 and the threaded port 2120 and maintain stable sealing performance during long-term use. At the same time, the locking effect of the threaded cap 2240 further enhances the stability of the connection and extends the service life of the nozzle assembly 220. In addition, a modular design is adopted, and the various components are tightly connected and easy to disassemble, which is convenient for installation and maintenance.

[0020] For further information, see Figure 1 and Fig. 9 , and also includes a support frame 500 for the device to be lifted off the ground. The support frame 500 includes a vertical pipe 510 fixedly installed on the ground in a vertical direction, and a platform 520 for the wind tube 100 and the water pump 300 to be installed is fixedly installed on the top of the vertical pipe 510. Among them, the support frame 500 can realize the elevated processing of the device. The elevated design not only helps to reduce the impact of ground dust on the device, but also increases the coverage of the dust reduction device, so that it can act more effectively in the construction area.

[0021] For further information, see Figure 1 and Fig. 9 , and also includes a spray module 600 installed on the platform 520, the spray module 600 includes a water distribution pipe 610 enclosed and arranged at the edge of the platform 520, and a plurality of second atomizing nozzles 620 are installed at the bottom of the water distribution pipe 610. Among them, in addition to the dust reduction effect of the water ring 200, the spray module 600 also plays an important role. The second atomizing nozzle 620 at the bottom of the water distribution pipe 610 sprays water mist evenly on the construction area around the platform 520, further supplementing the dust reduction effect. This dual dust reduction mechanism ensures that every corner of the construction area can be effectively covered.

[0022] For further information, see Fig.10 The output end of the water pump 300 is connected to the water ring 200 and the spray module 600 through a three-way fitting, and the input end of the water pump 300 is connected to the external water distribution network through a connecting water pipe. The connecting water pipe can be used to introduce water from the external water distribution network into the water pump 300. After the water pump 300 is started, the water can be transported to the water ring 200 and the spray module 600 respectively.

[0023] For further information, see Fig. 9 On the outer wall of the vertical pipe 510, there are welded several climbing frames 530 evenly distributed along its axial direction at equal distances. The top and bottom of the outer wall of the vertical pipe 510 and one side of several climbing frames 530 are provided with through holes 540 for connecting water pipes. Among them, the setting of the climbing frames 530 also provides convenience for the installation and maintenance of the construction personnel. The primary function of the through holes 540 is to serve as a channel for connecting water pipes. In the dust suppression device, the water pump 300 needs to transport water to the nozzle assembly 220 through the water pipe for atomization. Through the through holes 540 set at the top and bottom of the vertical pipe 510, the connecting water pipe can be routed internally through the vertical pipe 510, avoiding the potential safety hazards caused by the water pipe being directly exposed to the air, and also reducing the risk of the water pipe being damaged by the complex terrain or obstacles in the construction area. This internal routing method is not only beautiful and neat, but also improves the overall stability and safety of the device.

Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the present invention.
