Description

Technical Field

[0001] This utility model relates to the field of rock wool processing technology, specifically to a negative pressure dust collection device for reducing dust pollution in rock wool processing. Background Technology

[0002] In the rock wool processing industry, rock wool is a commonly used thermal insulation, heat insulation and sound absorption material with a wide range of applications, covering multiple fields such as building, industrial equipment insulation, and shipbuilding. However, in the production and processing of rock wool, especially in key processes such as cutting, grinding and trimming, a large amount of dust will inevitably be generated. These dust particles are small and numerous, and have strong diffusion and floating properties.

[0003] Currently, most of the dust collection devices equipped in rock wool processing workshops on the market have many problems that urgently need to be solved. Among them, the dust collection range of some dust collection devices is relatively narrow, and they can only cover a local area of ​​the processing area. For example, in the large-area cutting of rock wool, because the dust collection port is fixed in position and limited in number, it is impossible to capture dust generated from all directions. As a result, a large amount of dust spreads in the workshop, which not only seriously pollutes the working environment of the workshop, but also increases the difficulty and cost of subsequent cleaning work. Utility Model Content

[0021] Example 1

[0022] Please see Figure 1 As shown, this utility model provides a negative pressure dust collection device for reducing dust pollution in rock wool processing, including a support base 1, a processing platform 2 fixedly installed on the top of the support base 1, a support frame 3 fixedly installed on the bottom of the support base 1, a dust collection box 4 placed inside the support frame 3, a dust storage drawer pulled out inside the dust collection box 4, and three filter screens 5 installed at equal intervals inside the dust storage drawer, a gantry frame 6 fixedly installed on the outside above the support base 1, and dust collection pipes 11 installed on both the front and rear sides of the inner cavity of the gantry frame 6, a negative pressure fan 12 connected to the top of the dust collection pipe 11, a dust outlet pipe 13 connected to the dust outlet of the negative pressure fan 12, and the other end of the dust outlet pipe 13 connected to the inside of the dust collection box 4.

[0023] This technical solution features a well-defined internal structure with efficient space utilization. It ensures the overall stability of the device while rationally arranging the positions of each component, making the equipment compact and orderly. The dust collection drawer is installed in a pull-out manner, facilitating regular dust cleaning and reducing maintenance difficulty and costs. The three-layer filter screen 5 inside the dust collection drawer forms a graded filtration system, which can effectively intercept dust of different particle sizes, improve filtration accuracy, reduce environmental pollution, and extend the service life of the equipment. The gantry frame 6 has suction pipes 11 installed on the front and rear sides of its inner cavity, expanding the dust collection range. Combined with the powerful suction of the negative pressure fan 12, it can comprehensively and efficiently collect the dust generated during rock wool processing, keeping the processing environment clean.

[0024] Example 2

[0025] Based on Embodiment 1, this utility model is as follows: Figure 4 As shown, an electric cylinder 7 is fixedly installed on the top of the inner cavity of the gantry frame 6, and a cutter 8 is fixedly installed on the output end of the electric cylinder 7, with the cutter 8 corresponding to the upper part of the processing platform 2.

[0026] Adopting such Figure 1 The technical solution shown allows the electric cylinder 7 to move the cutter 8, enabling rapid adjustment of the cutter 8's position to complete the processing and cutting of rock wool.

[0027] Secondly, in the technical solution, a movable frame 9 is installed through the upper end of the gantry frame 6, and a screw 10 is threaded on the top of the movable frame 9. The lower end of the screw 10 is connected to the top of the gantry frame 6 through a bearing. A regulating valve 14 is movably installed on the surface of the middle end of the dust outlet pipe 13. A through groove is opened on the back of the support frame 3, and one end of the dust outlet pipe 13 is located inside the through groove.

[0028] Its adoption is as follows Figure 1 The technical solution shown has a movable frame 9 installed through the upper end of the gantry 6, providing stable support and a moving track for the movable frame 9. This allows the movable frame 9 to move precisely in the vertical direction on the gantry 6. This installation method ensures the stability and reliability of the movable frame 9 during movement, avoiding swaying or deviation during movement. This ensures that components such as the suction pipe associated with the movable frame 9 can be accurately positioned to the required location, improving the working accuracy of the entire vacuuming device.

[0029] Example 3

[0030] This utility model is as follows Figures 1-4 As shown, the top of the gantry 6 is provided with movable slots on both sides. The lower end of the movable frame 9 is located inside the movable slot and is slidably connected. The lower end of the movable frame 9 is rotatably installed with the upper end of the suction pipe 11. The filter screen 5 is installed at equal distances inside the dust collection drawer, and from top to bottom, they are the primary filter plate, the intermediate filter plate and the advanced filter plate.

[0031] By adopting the above technical solution, when the placement or processing position of the rock wool changes during the rock wool processing, the movable frame 9 can move accordingly, thereby driving the dust suction pipe 11 to be adjusted to a position closer to the dust generation source, which significantly improves the dust collection efficiency, ensures that the dust can be sucked into the dust suction pipe 11 in a timely and effective manner, reduces the spread of dust in the processing area, and minimizes the pollution to the surrounding environment. The dust suction pipe 11 can not only move with the movable frame 9, but also adjust its angle by rotation, giving full play to the role of the dust suction device.

[0032] The working principle of this utility model is as follows: Rock wool is placed on the processing platform 2, and the output end of the electric cylinder 7 drives the cutter 8 to move downward to cut the rock wool. During the cutting process, a large amount of dust is generated. When the rock wool processing generates dust, the negative pressure fan 12 is started, forming a negative pressure in the suction pipe 11. Since the suction pipe 11 is installed on the front and rear sides of the inner cavity of the gantry frame 6, it can suck the dust generated above the processing platform 2 into the suction pipe 11. The movable frame 9 can move on the gantry frame 6. The position of the movable frame 9 can be adjusted by rotating the screw 10. The lower end of the movable frame 9 is rotatably installed with the upper end of the suction pipe 11, which allows the position and angle of the suction pipe 11 to be adjusted according to the processing platform 2. Adjustments are made to meet operational needs, thereby more effectively collecting dust. Dust sucked into the suction pipe 11 is transported through the dust outlet pipe 13 connected to the top of the suction pipe 11 by the negative pressure fan 12. The regulating valve 14 on the middle surface of the dust outlet pipe 13 can control the flow rate and transmission speed of the dust. The dust enters the dust collection box 4 through the dust outlet pipe 13 into the dust storage drawer. Three filter plates 5 are installed at equal intervals inside the dust storage drawer, namely the primary filter plate, the intermediate filter plate, and the high-grade filter plate. When the dust passes through these filter plates 5, dust of different particle sizes is intercepted by each level of filter plate in turn, while the dust is retained on the filter plates 5 in the dust storage drawer. The dust storage drawer can be cleaned periodically by removing it.
