[0002] The negative pressure dust removal device in the kernel production line is a device used to collect and treat the dust generated during the kernel production process. It effectively controls the spread of kernel dust in the workshop and reduces the dust concentration in the workshop air.
[0003] In the existing technology, although the negative pressure dust removal device in the kernel production line can play a certain role in dust removal, the air volume of the negative pressure system is fixed and cannot be adjusted according to the actual dust generation at different dust generation points. When the dust generation is low, the system still operates with a large air volume, resulting in energy waste and increased operating costs. When the dust generation is high, the fixed air volume may not be able to meet the dust removal needs, resulting in low dust removal efficiency. Utility Model Content

Therefore, this invention proposes a negative pressure dust removal device for kernel production lines.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a negative pressure dust removal device for a kernel production line, comprising a support frame and a frequency converter. An adjustment device is provided on one side of the support frame. The adjustment device includes a base plate, one side of which is fixedly connected to the support frame. A housing is fixedly connected to one side of the base plate. A negative pressure fan is fixedly connected to the inner side of the housing. An externally threaded pipe is fixedly connected to one side of the housing. The arc surface of the externally threaded pipe is fixedly connected to the support frame. An internally threaded pipe is threadedly connected to the arc surface of the externally threaded pipe. A flanged pipe is fixedly connected to one end of the internally threaded pipe. A negative pressure sealed dust removal hood is fixedly connected to one end of the flanged pipe. A dust concentration sensor is fixedly connected to the inner side of the negative pressure sealed dust removal hood.
[0006] The aforementioned components achieve the following effects: the negative pressure fan generates negative pressure upon startup, creating a negative pressure state inside the sealed dust collector hood, which in turn draws dust into the flange pipe, transports it to the external threaded pipe, and discharges it into the outer casing. Simultaneously, the dust concentration sensor detects the amount of dust in real time.
[0007] Preferably, a dust collection box is fixedly connected to one side of the base plate, and an activated carbon block is fixedly connected to the inner side of the dust collection box.
[0008] The effect achieved by the above components is to achieve the effect of activated carbon blocks filtering dust.
[0009] Preferably, a plurality of anti-slip strips are fixedly connected to the arc surface of the internally threaded tube, and the plurality of anti-slip strips are evenly distributed on the internally threaded tube.
[0010] The effect achieved by the above components is to increase the friction of the anti-slip strip.
[0011] Preferably, the arc surface of the internally threaded tube is fixedly connected to three support frames, and one side of the three support frames is fixedly connected to a negative pressure sealed dust collector.
[0012] The effect achieved by the above components is to provide a reinforced negative pressure sealed dust collector with a support frame.
[0013] Preferably, a fixing device is provided on one side of the support frame. The fixing device includes a fixing plate, one side of which is fixedly connected to the support frame. A handle is fixedly connected to one side of the fixing plate, and the handle has an "L" shaped cross-section.
[0014] The above components achieve the following effect: the handle is fixed to the fixed plate, and the fixed plate is fixed to the support frame.
[0015] Preferably, a limit ring is fixedly connected to the arc surface of the handle.
[0016] The effect achieved by the above components is to fix the limiting ring to the handle.
[0017] Preferably, one end of the handle is fixedly connected to a screw.
[0018] The effect achieved by the above components is to fix the screw to the handle.
[0019] Preferably, the screw has an internal threaded ring connected to its arc-shaped surface.
[0020] The effect achieved by the above components is that the internal threaded ring and the screw are properly matched.
[0021] Preferably, the arc surface of the handle is covered with an anti-slip sleeve, which is made of rubber.
[0022] The effect achieved by the above components is to increase friction by implementing anti-slip sleeves.
[0023] In summary, the beneficial effects of this utility model are as follows:
[0024] In this invention, by means of an adjustment device, when dust treatment is required at the dust-generating points of the kernel production line, a negative pressure sealed dust collection hood can be flexibly installed according to the layout of each dust-generating point. The dust concentration sensor will monitor the dust concentration in real time and transmit the data synchronously to the frequency converter to control the speed of the negative pressure fan for dust removal. By means of an adjustment device, the problem of traditional negative pressure dust removal devices in kernel production lines, which can play a certain role in dust removal, but whose air volume is fixed and cannot be adjusted according to the actual amount of dust generated at different dust-generating points is solved.
[0025] In this invention, by means of a fixing device, when the negative pressure dust removal device needs to be moved, the anti-slip sleeve is held and a continuous pulling force is applied. This pulling force is transmitted to the handle through the anti-slip sleeve, which in turn drives the fixing plate connected to the handle, causing the fixing plate to move the support frame synchronously. By means of a fixing device, the problem of the traditional negative pressure dust removal device in the kernel production line being inconvenient to move due to its external inaccessibility is solved.

[0031] Reference Figure 1 As shown, this utility model provides a technical solution: a negative pressure dust removal device for a kernel production line, including a support frame 1 and a frequency converter 4. An adjustment device 2 is provided on one side of the support frame 1, and a fixing device 3 is provided on one side of the support frame 1.
[0032] The specific settings and functions of the adjustment device 2 and the fixing device 3 will be described in detail below.
[0033] Reference Figure 2and Figure 3 As shown in this embodiment: the adjusting device 2 includes a base plate 201, one side of the base plate 201 is fixedly connected to the support frame 1, a housing 205 is fixedly connected to one side of the base plate 201, a negative pressure fan 204 is fixedly connected to the inner side of the housing 205, an external threaded pipe 206 is fixedly connected to one side of the housing 205, the arc surface of the external threaded pipe 206 is fixedly connected to the support frame 1, an internal threaded pipe 207 is threadedly connected to the arc surface of the external threaded pipe 206, a flanged pipe 209 is fixedly connected to one end of the internal threaded pipe 207, a negative pressure sealed dust collector hood 210 is fixedly connected to one end of the flanged pipe 209, and a dust concentration sensor 211 is fixedly connected to the inner side of the negative pressure sealed dust collector hood 210. The system achieves the effect of negative pressure fan 204 starting to generate negative pressure, creating a negative pressure state inside the negative pressure sealed dust collector hood 210. This causes external air to carry dust into the flange pipe 209, which is then transported to the external threaded pipe 206 and discharged into the outer casing 205. The dust concentration sensor 211 detects the dust amount in real time during the suction process. A dust collection box 202 is fixedly connected to one side of the base plate 201, and an activated carbon block 203 is fixedly connected to the inside of the dust collection box 202. This achieves the effect of activated carbon block 203 filtering dust. Several anti-slip strips 208 are fixedly connected to the arc surface of the internal threaded pipe 207, and these anti-slip strips 208 are evenly distributed on the internal threaded pipe 207. This achieves the effect of anti-slip strips 208 increasing friction. Three support frames 212 are fixedly connected to the arc surface of the internal threaded pipe 207, and one side of each support frame 212 is fixedly connected to the negative pressure sealed dust collector hood 210. It achieves the effect of supporting the frame 212 and reinforcing the negative pressure sealed dust collector hood 210.
[0034] Reference Figure 4 As shown in this embodiment: the fixing device 3 includes a fixing plate 31, one side of which is fixedly connected to the support frame 1, and a handle 32 is fixedly connected to one side of the fixing plate 31. The handle 32 has an "L"-shaped cross-section. This achieves the effect of fixing the handle 32 to the fixing plate 31, and fixing the fixing plate 31 to the support frame 1. A limiting ring 33 is fixedly connected to the arc surface of the handle 32. This achieves the effect of fixing the limiting ring 33 to the handle 32. A screw 35 is fixedly connected to one end of the handle 32. This achieves the effect of fixing the screw 35 to the handle 32. An internal threaded ring 36 is threadedly connected to the arc surface of the screw 35. This achieves the effect of matching the internal threaded ring 36 and the screw 35. An anti-slip sleeve 34, made of rubber, is fitted onto the arc surface of the handle 32. This achieves the effect of increasing friction with the anti-slip sleeve 34.
[0035] Working Principle: When dust control is required at the dust-generating points of the kernel production line via the adjustment device 2, the operator first flexibly installs the negative pressure sealed dust collector hood 210 according to the layout of each dust-generating point. By rotating the inner threaded tube 207, its position on the outer threaded tube 206 is adjusted, thereby moving the flange tube 209 and the negative pressure sealed dust collector hood 210 until they are tightly fitted to the dust-generating point, forming an efficient dust capture space. After the kernel production line starts operating, the dust concentration sensors 211 distributed at each dust-generating point will monitor the dust concentration in real time and transmit the data synchronously to the frequency converter 4. Based on the received dust concentration signal, the frequency converter 4 intelligently controls the start-up and speed of the negative pressure fan 204, automatically adjusting the output of the negative pressure fan 204. The air volume is adjusted to ensure optimal dust removal efficiency under varying dust levels. Dust-laden airflow, under negative pressure, sequentially passes through the negative pressure sealed dust collector hood 210, flange tube 209, and external threaded tube 206 before entering the outer casing 205, ultimately converging into the dust collection box 202. The activated carbon block 203 installed inside the dust collection box 202 fully utilizes its adsorption and filtration functions to deeply purify the dust, effectively intercepting and adsorbing dust particles. The purified air is then discharged after subsequent system treatment, achieving efficient collection and purification of dust during kernel production. The adjustment device 2 addresses the problem that traditional negative pressure dust collectors in kernel production lines, while effective in dust removal, have a fixed airflow that cannot be adjusted according to the actual dust generation at different points.
[0036] With the fixing device 3, when the negative pressure dust removal device needs to be moved, the operator first holds the anti-slip sleeve 34 on the device and continuously applies a pulling force. This pulling force is transmitted to the handle 32 through the anti-slip sleeve 34, which in turn drives the fixing plate 31 connected to the handle 32, causing the fixing plate 31 to move the support frame 1 synchronously. This enables the convenient relocation of the negative pressure dust removal device, ensuring that the equipment can flexibly adapt to the needs of different working scenarios. With the fixing device 3, the problem of the traditional negative pressure dust removal device in the kernel production line being inconvenient to move due to the difficulty in taking it out from the outside is solved.
