Description

Technical Field

[0001] The invention relates to the technical field of stone processing, and in particular to a device for cutting, grinding and removing dust from special-shaped stone parts and a use method thereof. Background Art

[0002] In the process of stone processing and production, the main production links that are prone to dust pollution or dust hazards are burning, sandblasting, and cutting and grinding of special-shaped parts. Most burning machines and sandblasting machines have adopted dust prevention measures such as bag dust removal. At present, during the production of cutting and grinding of special-shaped parts, due to the particularity of its operation and the constraints of existing dust removal methods, there is often a situation where the dust concentration in the air of the workplace exceeds the standard.

[0003] Special-shaped parts range from stone benches and stone pillars to stone lions, and their shapes and sizes vary. During production, workers need to work around the special-shaped parts to grind and cut them. The cutting and grinding production of special-shaped stone parts has the following characteristics: (1) Special-shaped parts are mainly customized according to customer requirements (such as stone benches, stone pillars or stone lions, etc.), and their appearance, shape and size vary, so they cannot be mechanized or produced on an assembly line; (2) Workers mainly use handheld cutting machines, chiseling machines, grinders or polishing machines for manual work; (3) A lot of dust is generated during the cutting, grinding and polishing production process, and the dust concentration in the air is high and often exceeds the standard; (4) Workers generally work around the special-shaped parts, and their working positions are not fixed; (5) The dust generated is mainly silica dust, and workers are prone to pneumoconiosis if they are exposed to it for a long time.

[0004] The existing dust removal for cutting and grinding of special-shaped stone parts has the following disadvantages: Since conventional dust hoods cannot collect dust in the air in time, the actual effect is poor, and stone processing companies often directly stop using such dust removal devices. The dust generated by stone processing often has a free silica content of more than 10%, which is silica dust, which is harmful to the lungs of on-site workers. If workers are exposed to high dust concentrations in the air for a long time, there is a major risk of pneumoconiosis.

[0055] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0056] Embodiment 1:

[0057] This embodiment provides a device for cutting, grinding and removing dust from special-shaped stone parts. Figure 1 As shown, it includes: a dust hood 1, a dust collector 2 and a water supply device 3, wherein:

[0058] One end of the dust hood 1 is connected to the dust collector 2, one side of the dust collector 2 faces the interior of the dust hood 1, and an air inlet 21 is provided on the side of the dust collector 2 facing the interior of the dust hood 1, and the dust collector 2 is connected to the water supply device 3.

[0059] The interior of the dust hood 1 is used for stone operations, the air inlet 21 is used to suck the dust inside the dust hood 1 into the dust collector 2, the water supply device 3 is used to transport liquid to the first nozzle 22 inside the dust collector 2, the first nozzle 22 sprays the liquid into the interior of the dust collector 2 in the form of water mist, and the dust and water mist in the dust collector 2 are combined into dust particles and deposited in the dust collector 2.

[0060] In this embodiment, the dust hood 1 includes a frame and an external mask layer. The frame is used to support the structural space of the entire dust hood 1. The frame is distributed on both sides and the top and extends in the radial direction. There is a large amount of space in the middle of the frame for workers to move and work. There are openings at both ends of the frame for workers to enter and exit or communicate with the outside world. The external mask layer is set on the outer part of the frame to isolate the two sides and the top of the entire dust hood 1 from the outside world, so as to prevent the dust generated by the workers when working on the stone from directly diffusing to the outside. Openings are left at both ends of the dust hood 1, one end of which is used for workers to enter and exit, and the other end is used to connect with the dust collector 2, so as to connect the inside of the dust hood 1 with the dust collector 2.

[0061] In this embodiment, the dust collector 2 is used to absorb the dust inside the dust hood 1 and process the dust absorbed inside the dust collector 2. A fan is provided at the air inlet 21. When the fan is turned on, the airflow outside the dust collector 2 is transported to the inside of the dust hood 1, thereby sucking the dust inside the dust hood 1 into the dust collector 2. The corresponding dust suction air volume can be 70000±10m 3 / h, the average wind speed in the dust hood 1 can be 1.9±0.1m / s; the first nozzle 22 is located inside the dust collector 2 and connected to the water supply device 3, and the liquid is transported to the inside of the dust collector 2 through the water supply device 3, and sprayed into the inside of the dust collector 2 through the first nozzle 22, wherein the first nozzle 22 inside the dust collector 2 can be 8, and the diameter of the water droplets in the water mist sprayed by the first nozzle 22 can be 7.07±0.01 microns. When the water mist and dust come into contact in the dust collector 2, they condense into relatively large solid particles and sink to the lower end of the dust collector 2 under the action of gravity. The above process completes the absorption of the dust inside the dust hood 1, effectively reduces the dust concentration in the air inside the dust hood 1 in real time, and avoids the staff working in the dust hood 1 from being in the air with seriously excessive dust concentration for a long time.

[0062] Furthermore, in this embodiment, in order to ensure the normal circulation of the internal airflow and the communication between the first nozzle 22 and the external water supply device 3, the dust collector 2 also involves the following designs:

[0063] like Figure 2 and Figure 3As shown, the dust collector 2 also includes a box body 23, an air outlet 24 and a water pipe 25, wherein: one end of the dust hood 1 is connected to one side of the box body 23, and one side of the box body 23 faces the interior of the dust hood 1; the air inlet 21 is arranged on the side of the box body 23 facing the interior of the dust hood 1 and leads to the interior of the box body 23, the air outlet 24 is arranged at the upper end of the box body 23 and leads to the interior of the box body 23, the water pipe 25 is located inside the box body 23, and one end of the water pipe 25 is arranged on the inner side wall of the box body 23 and leads to the outside of the box body 23 and connects with the water supply device 3, and the first nozzle 22 is arranged on the water pipe 25; the air outlet 24 is used to discharge the airflow sucked into the interior of the box body 23 by the air inlet 21, and the water pipe 25 is used to transport the liquid from the water supply device 3 and output the liquid to the interior of the box body 23 through the first nozzle 22.

[0064] like Figure 2 and Figure 3 As shown, the height of the water pipe 25 is higher than the height of the air inlet 21 .

[0065] In this embodiment, the dimensions of the box 23 can be: 5±0.1m in length, 1±0.1m in width, and 3.2±0.1m in height. The height of the water pipe 25 in the box 23 is higher than the height of the air inlet 21. Since the air outlet 24 is located at the upper end of the box 23, the airflow entering the box 23 will flow upward. The first nozzle 22 is arranged on the water pipe 25 and sprays downward, just toward the upward airflow. The water mist collides with the dust in the airflow, so that most of the dust in the airflow is condensed into particles. The dust concentration in the airflow output from the air outlet 24 is greatly reduced. At this time, the dust is discharged to the outside air through the air outlet 24, which can greatly reduce the impact of the dust.

[0066] Furthermore, in the present embodiment, the water mist concentration in the dust collector 2 can also be adjusted according to the dust concentration in the airflow, wherein a dust concentration detector is provided at any position on the box body 23 located on the side of the dust collector 2, and the dust concentration detector is used to monitor the dust concentration of the airflow entering the air inlet 21 in real time, and upload the corresponding dust concentration to the host in real time, and the host controls the number of the first nozzles 22 in the dust collector 2 that are opened according to the dust concentration. When the dust concentration is higher, more first nozzles 22 are controlled to be opened, so that the water mist concentration in the dust collector 2 is increased to cope with the airflow with a higher dust concentration. When the dust concentration is lower, relatively fewer first nozzles 22 can be controlled to be opened, thereby reducing water consumption.

[0067] In this embodiment, when the solid particles condensed and precipitated inside the dust collector 2 reaches a preset thickness, the operator opens the inspection door and enters the interior to bag the semi-dry solid particles. The moisture content of the semi-dry solid particles is about 6%, and there is no need to dry them in the sun. They can be directly transported out to avoid environmental pollution. The bagged solid particles can be directly transported to the garbage disposal station, eliminating all the mud drying steps of conventional wet dust collectors. While reducing the production costs of the enterprise, it also avoids the secondary environmental pollution that may be caused by the mud. In addition, the semi-dry powder ash will not form secondary dust during the treatment process, thereby improving the working environment during the collection and treatment process.

[0068] Furthermore, in this embodiment, one end of the dust hood 1 is provided with an opening, which is used for workers to enter and exit. Considering the space occupied by the corresponding device, when stone work is required, the dust hood 1 needs to provide sufficient space, and when stone work is not required, the space occupied by the dust hood 1 is relatively wasted, so this embodiment also involves the following designs:

[0069] like Figure 4 and Figure 5 As shown, the dust hood 1 includes: a telescopic frame 11, a canvas 12 and an air curtain machine 13, wherein: the canvas 12 is arranged on the telescopic frame 11, the telescopic frame 11 and the dust collector 2 are connected, the air curtain machine 13 is arranged on the top of the telescopic frame 11, and the air outlet direction of the air curtain machine 13 is toward the inside of the telescopic frame 11.

[0070] In this embodiment, the skeleton of the dust hood 1 can be the telescopic frame 11, and the external mask layer can be a canvas 12. The telescopic frame 11 can be expanded or compressed in the radial direction, and drive the canvas 12 on the telescopic frame 11 to be expanded or compressed synchronously. When stone operations are required, the dust hood 1 can be expanded to provide a larger internal working space. When stone operations are not required, the dust hood 1 is compressed, thereby greatly reducing the space area occupied by the dust hood 1.

[0071] The air curtain 13 is arranged at the upper end of the outlet of the dust hood 1, and the air outlet direction is biased toward the inside of the dust hood 1. Figure 4 The middle arrow indicates the air outlet direction of the air curtain machine 13. In this embodiment, the air curtain machine 13 can generate a 15 m / s induced airflow. At the outlet position, most of the dust inside the dust hood 1 is confined inside the dust hood 1 by the induced airflow, which greatly reduces the amount of dust diffused to the outside of the dust hood 1.

[0072] Furthermore, in order to ensure the smoothness and ease of operation of the expansion or compression of the telescopic frame 11 of the dust hood 1, the present embodiment also involves the following designs:

[0073] like Figure 4 and Figure 5 As shown, the dust hood 1 also includes a guide rail 14 and a sliding wheel 15, wherein: the guide rail 14 is located at the lower end of the telescopic frame 11, and one end of the guide rail 14 is fixed to the lower end of the telescopic frame 11 facing the dust collector 2; the sliding wheel 15 is located at the lower end of the telescopic frame 11 facing away from the dust collector 2, and the sliding wheel 15 is slidably fitted on the guide rail 14; the compression or expansion of the telescopic frame 11 is achieved by sliding the sliding wheel 15 on the guide rail 14.

[0074] Furthermore, in this embodiment, considering that although the air inlet 21 of the dust collector 2 absorbs the dust airflow inside the dust hood 1 in real time, since the staff is directly inside the dust hood 1, a large amount of dust will still be inhaled during the operation. Therefore, in order to further reduce the amount of dust inhaled by the staff during the operation and further reduce the harm of dust to the staff, this embodiment also involves the following designs:

[0075] like Figure 6 As shown, a plurality of cameras 16 and a plurality of second nozzles 17 are further provided at the upper end of the inner side of the telescopic frame 11, wherein: the plurality of cameras 16 are arranged in sequence at uniform intervals along the telescopic direction of the telescopic frame 11, and the plurality of second nozzles 17 are arranged in sequence at uniform intervals along the telescopic direction of the telescopic frame 11, and each camera 16 corresponds to one of the second nozzles 17 one by one; the cameras 16 are used to monitor the interior of the telescopic frame 11, and when there are workers working directly below one or more cameras 16, the second nozzles 17 corresponding to the other cameras 16 except the corresponding camera 16 are turned on; the second nozzles 17 are used to spray water mist directly below to condense the dust below the second nozzles 17 into dust particles and precipitate them.

[0076] In this embodiment, the interior of the dust hood 1 can be divided into a plurality of areas at equal distances in the radial direction, and at least one camera 16 and at least one second nozzle 17 are correspondingly arranged above each area. When the staff is working, all the cameras 16 in the dust hood 1 are turned on, and the area directly below is monitored and detected by the cameras 16. When the camera 16 detects that there are staff in the area directly below, the second nozzles 17 in other areas except for the staff are turned on, and the liquid sprayed by the second nozzles 17 is directly used to condense the dust in other areas except for the staff. Figure 6The arrow in the middle is the water outlet direction of the second nozzle 17. The condensed solid particles settle to the bottom of the dust hood 1 under the action of gravity. In order to prevent the staff from being directly sprayed by the spray, the second nozzle 17 in the area where the staff is located is not turned on. Through the above method, the dust inside the dust hood 1 can be directly condensed and processed. In conjunction with the dust collector 2, on the one hand, the dust concentration inside the dust hood 1 can be effectively reduced, reducing the harm of dust to the staff, and on the other hand, the efficiency of dust processing can be further improved.

[0077] In this embodiment, a corresponding water pipe can be set at the inner upper end of the telescopic frame 11. The water pipe can be a hose. The water pipe extends along the radial direction of the telescopic frame 11, and corresponding second nozzles 17 are installed at intervals to achieve the above design.

[0078] Furthermore, since the second nozzle 17 directly above the position of the worker is not turned on, the dust concentration at the position of the worker is still high, and the position of the worker is the position where the dust is generated, the dust concentration at this position is relatively the highest, and the worker theoretically still inhales relatively more dust. Therefore, in order to solve this problem, this embodiment also involves the following design:

[0079] like Figure 6 and Figure 7 As shown, the multiple fans 18 are arranged in sequence at uniform intervals along the telescopic direction of the telescopic frame 11, and each fan 18 corresponds to one of the cameras 16 one by one; the camera 16 is used to monitor the inside of the telescopic frame 11. When there are workers working directly below one or more cameras 16, the fans 18 corresponding to the two cameras 16 on both sides of the corresponding camera 16 are turned on, and the air outlet direction of the turned-on fans 18 is toward the location of the workers, so as to blow the dust at the location of the workers to the adjacent areas on both sides of the workers and be processed by the second nozzles 17 in the adjacent areas.

[0080] In this embodiment, the interior of the dust hood 1 can be divided into a plurality of regions at equal distances in the radial direction, and at least one camera 16, at least one second nozzle 17 and at least one fan 18 are correspondingly arranged above each region. Figure 7 As shown, when the staff is working, all the cameras 16 in the dust hood 1 are turned on, and the area directly below is monitored and detected by the cameras 16.
