Description

Technical Field

[0001] This utility model belongs to the field of float glass technology and equipment, and particularly relates to a dust removal device and a float glass production line. Background Technology

[0002] Currently, the dust removal in the edge cleaning and dropping area and the dust removal in the main dropping area of ​​the float glass production line are two separate dust removal systems, designed to meet the maximum load of all continuous dropping of the glass produced by the production line (i.e., equal to the pulling amount of the line).

[0003] However, during normal production, the amount of defective sheets dropped in the edge cleaning and dropping area is very small (generally less than 10% of the pulling amount), so the amount of dust generated during normal production is not large, about 10% of the total amount of glass strips dropped continuously. If both dust removal systems operate at full load at the same time, the dust removal capacity will be seriously excessive, resulting in a waste of electricity.

[0004] To address the issue of wasted electricity during normal production, the dust collector fan motor can be designed with a variable frequency drive (VFD). During normal production, the frequency can be appropriately lowered (to about 30% of the rated power), and then increased back to 100% during continuous plate dropping to ensure a qualified dust removal efficiency of over 99.0%. However, VFD motors are expensive. Utility Model Content

[0021] Please see Figures 1 to 2 This application provides a dust removal device 100 and a float glass production line having the same. The float glass production line has an edge cleaning area and a main line drop area.

[0022] A dust removal device 100 is used to remove dust from a first area 101 and a second area 102, which are arranged alternately. In this embodiment, the first area 101 and the second area 102 are respectively the edge cleaning and unloading area and the main line unloading area of ​​the production line.

[0023] Please see Figures 1 to 2 The dust removal device 100 includes: a pipeline assembly 10, a control assembly 20, and a fan assembly 30.

[0024] Please see Figures 1 to 2 The piping assembly 10 includes a main dust collection pipe 11 and a bypass branch pipe 12. The main dust collection pipe 11 and the bypass branch pipe 12 can be made of metal, such as stainless steel, aluminum alloy, or copper. In this embodiment, the main dust collection pipe 11 and the bypass branch pipe 12 are made of cast iron. Cast iron has high strength and excellent corrosion resistance. The protective layer formed by the graphite structure extends its service life and provides outstanding shock resistance. Simultaneously, the flake graphite structure of gray cast iron effectively reduces noise, making it suitable for high-pressure dust and fluid transport. The main dust collection pipes 11 are spaced apart at both ends, with one end of each main dust collection pipe 11 extending to the first region 101 and the second region 102, respectively. One end of each main dust collection pipe 11 is connected to both ends of the bypass branch pipe 12; thus, dust can flow from one main dust collection pipe 11 to the other main dust collection pipe 11 through the bypass branch pipe 12.

[0025] Please see Figures 1 to 2The control component 20 includes two control valves 21, each connected to one of the two dust collection main pipes 11. Each control valve 21 is used to open or close its corresponding dust collection main pipe 11. When a control valve 21 is open, the corresponding dust collection main pipe 11 is open, allowing dust from the first region 101 to flow into one end of the corresponding dust collection main pipe 11 under negative pressure and out the other end. Similarly, dust from the second region 102 can flow into one end of the corresponding dust collection main pipe 11 under negative pressure and out the other end. When a control valve 21 is closed, the corresponding dust collection main pipe 11 is blocked, preventing dust from flowing into it.

[0026] Please see Figures 1 to 2 The fan assembly 30 includes a first fan 31 and a second fan 32. The first fan 31 and the second fan 32 are respectively connected to the other ends of the two dust collection main pipes 11, so that the two dust collection main pipes 11 generate negative pressure on the first region 101 and the second region 102 respectively. It is understood that the first fan 31 generates negative pressure in the first region 101 through one of the dust collection main pipes 11 and extracts dust from the first region 101. The second fan 32 generates negative pressure in the second region 102 through the other dust collection main pipe 11 and extracts dust from the second region 102.

[0027] Please see Figures 1 to 2 It is understood that when the dust collector 100 is in operation, at least one control valve 21 is in the open state; for example, one control valve 21 is in the open state, one control valve 21 is in the closed state, or both control valves 21 are in the open state. When the dust collector 100 is in the shutdown state, both control valves 21 are in the closed state simultaneously.

[0028] Please see Figures 1 to 2 Optionally, the rated power of the first fan 31 and the rated power of the second fan 32 are different. For example, the rated power of the first fan 31 is greater than the rated power of the second fan 32. The rated power of the first fan 31 is 75kW and the rated power of the second fan 32 is 50kW.

[0029] When there is relatively little dust, only the second fan 32 can be turned on and the first fan 31 can be turned off, with the first fan 31 serving as a backup. At the same time, the control valve 21 corresponding to the first fan 31 can be closed, thereby allowing the second fan 32 to simultaneously remove dust from the first area 101 and the second area 102.

[0030] Please see Figures 1 to 2When there is a lot of dust, only the first fan 31 can be turned on and the second fan 32 can be turned off, with the second fan 32 serving as a backup. At the same time, the control valve 21 corresponding to the second fan 32 can be turned off, so that the first fan 31 can simultaneously remove dust from the first area 101 and the second area 102.

[0031] Furthermore, when there is a lot of dust in both the first zone 101 and the second zone 102, the first fan 31 and the second fan 32 can be turned on at the same time, and both control valves 21 are in the open state.

[0032] Please see Figures 1 to 2 In this embodiment, the dust removal of the first area 101 and the second area 102 is connected through two dust removal main pipes 11 and a bypass branch pipe 12. Combined with two control valves 21, a first fan 31 and a second fan 32, the first fan 31 or the second fan 32 can be shut down during normal production. The dust removal paths of the two dust removal main pipes 11 are merged through the bypass branch pipe 12 to achieve mutual backup and power saving. This avoids excessive dust removal capacity in the edge clearing and dropping areas and the main line dropping areas of the float glass production line, thereby reducing energy consumption. The dust removal device 100 has a simple structure and low cost. Ultimately, it achieves the connection, merging, mutual backup and energy saving of the two dust removal main pipes 11, and ensures dust removal efficiency.

[0033] The dust removal device 100 provided in this application achieves the purpose of saving electricity at a low cost, and can be applied to most float glass production lines, showing strong versatility.

[0034] Please see Figures 1 to 2 In some embodiments, the bypass branch pipe 12 is located in front of the dust removal main pipe 11 along the gas flow direction.

[0035] Alternatively, by designing the bypass branch pipe 12 to be connected in front of the control valve 21 along the gas flow direction, it is ensured that when one control valve 21 is closed, the gas can smoothly enter another dust removal main pipe 11 through the bypass branch pipe 12, thereby optimizing the airflow path and reducing resistance loss and energy waste.

[0036] Please see Figures 1 to 2 In some embodiments, the dust removal main pipe 11 includes a first pipe section 111 and a second pipe section 112 connected to the first pipe section 111. The control valve 21 and the bypass branch pipe 12 are both connected to the first pipe section 111. The two first pipe sections 111 extend to the first region 101 and the second region 102, respectively. The first fan 31 and the second fan 32 are respectively connected to the two second pipe sections 112.

[0037] Optionally, by dividing the dust removal main pipe 11 into a first pipe section 111 and a second pipe section 112, the control valve 21 and the bypass branch pipe 12 are connected to the first pipe section 111, while the first fan 31 and the second fan 32 are respectively connected to the two second pipe sections 112. The first pipe section 111 and the second pipe section 112 can be detachably connected by a flange structure, which not only simplifies the pipeline layout but also facilitates installation and maintenance.

[0038] Please see Figures 1 to 2 In some embodiments, the first pipe segment 111 is arranged in a vertical direction, and the second pipe segment 112 is arranged in a horizontal direction. In the first region 101, the first pipe section 111 is arranged vertically, which facilitates the absorption of dust in the first region 101. The first fan 31 is located in the horizontally arranged second pipe section 112, which can optimize the gravity-assisted flow of airflow, reduce the risk of dust accumulation and pipe blockage, and improve dust removal efficiency.

[0039] In the second region 102, the first pipe section 111 is arranged vertically, which facilitates the absorption of dust in the second region 102 by the first pipe section 111. The second fan 32 is located in the horizontally arranged second pipe section 112, which can optimize the gravity-assisted flow of airflow, reduce the risk of dust accumulation and pipe blockage, and improve dust removal efficiency.

[0040] Optionally, the first pipe section 111 is bent and meandered in the vertical direction, and the second pipe section 112 is bent and meandered in the horizontal direction.

[0041] Please see Figures 3 to 4 In some embodiments, the first pipe section 111 has a plug groove 113 that communicates with its inner cavity, and the control valve 21 includes a slide valve 211 and a handle 212. One end of the slide valve 211 is slidably inserted into the plug groove 113, and the handle 212 is connected to the other end of the slide valve 211.

[0042] It is understandable that the shape of the insertion end of the slide valve 211 is adapted to the shape of the cross-section of the first pipe section 111, so that after the slide valve 211 is fully inserted into the first pipe section 111, the slide valve 211 can completely close the first pipe section 111.

[0043] Please see Figures 3 to 4 The slide gate valve 211 can be easily operated manually via the handle 212, enabling manual and quick opening and closing, simplifying the control process. It has a simple structure and is easy to operate.

[0044] Please see Figures 3 to 4Optionally, in this embodiment, the cross-sectional shape of the first pipe segment 111 is circular, and the insertion groove 113 extends circumferentially along the first pipe segment 111, with the arc length of the extension path being half a circle, thereby facilitating the insertion of the gate valve 211 into and out of the first pipe segment 111.

[0045] Please see Figures 3 to 4 In some embodiments, the control valve 21 further includes a sealing ring disposed at the edge of the insertion groove 113, and the insert valve 211 is inserted into the sealing ring.

[0046] Optionally, the sealing ring can be made of an elastic material, such as rubber or silicone. When the slide gate valve 211 is inserted into the sealing ring, the sealing ring undergoes a slight elastic deformation, thereby wrapping around the slide gate valve 211 while not completely restricting its sliding. The sealing ring ensures the sealing performance of the slide gate valve 211 during insertion, preventing gas leakage and dust escape, thus improving dust removal efficiency and safety.

[0047] Please see Figures 3 to 4 In some embodiments, the dust removal device 100 further includes a support rod 22 connected to the first pipe section 111. The length direction of the support rod 22 is arranged along the sliding direction of the slide valve 211. The slide valve 211 slides out of the insertion slot 113 and is supported by the support rod 22.

[0048] Optionally, the support rod 22 is arranged horizontally and is used to support the slide gate valve 211 in the vertical direction, so that the slide gate valve 211 can adjust the opening of the first pipe section 111. For example, when it is not necessary to fully open the first pipe section 111, part of the slide gate valve 211 remains in the first pipe section 111. At the same time, another part of the slide gate valve 211 is supported on the support rod 22, so that the opening of the first pipe section 111 can be adjusted according to different dust amounts, thereby improving the convenience of use.

[0049] Optionally, two support rods 22 are arranged at intervals.

[0050] Please see Figures 3 to 4 Optionally, both the support rod 22 and the slide valve 211 are made of iron. The other end of the slide valve 211 is also equipped with a magnet. After the slide valve 211 is adjusted to the correct position, the support rod 22 and the slide valve 211 are magnetically connected by the magnet.

[0051] It is also understandable that the support rod 22 is arranged horizontally, and the two ends of the support rod 22 are respectively connected to the two first pipe sections 111. The support rod 22 can improve the stability and structural strength of the two first pipe sections 111.

[0052] Please see Figures 1 to 2In some embodiments, the dust removal device 100 further includes a dust collection hood 40, two dust collection hoods 40 are provided, and the two dust collection hoods 40 are respectively connected to one end of the dust removal main pipe 11.

[0053] Optionally, the dust collection hood 40 is shaped like an inverted funnel, which can expand the dust collection range and improve the dust removal effect.

[0054] Please see Figures 1 to 2 In some embodiments, the dust removal device 100 further includes a dust removal box and a filter bag disposed in the dust removal box and connected to the air outlet of the dust removal main pipe 11. Each of the dust removal main pipes 11 is correspondingly provided with the filter bag and the dust removal box. Optionally, by adding a dust collection box and filter bag to the outlet of the dust collection main pipe 11, dust filtration and collection can be achieved to ensure clean exhaust gas.

[0055] The dust removal device 100 can play a role in dust removal and environmental protection in areas with excessive dust. The dust removal device 100 includes a dust removal box, filter bags located inside the dust removal box, a fan assembly 30, a control assembly 20, and a pipeline assembly 10. The dust removal box contains several filter bags and supports for supporting the filter bags. After the dust-containing gas enters the dust removal box from the second pipe section 112, the dust is filtered out by the filter bags and deposited at the bottom of the box, and then unloaded and collected. The cleaner air is drawn out from the middle of the filter bags by the fan through the air duct and then discharged into the atmosphere at a higher altitude through the pipeline.

[0056] Optionally, both the first fan 31 and the second fan 32 can be centrifugal fans.

[0057] Optionally, the dust removal device 100 is also used to remove dust from a third area. The first area 101, the second area 102, and the third area are arranged at intervals. Three main dust removal pipes 11 are arranged, and two bypass branch pipes 12 are provided. The three main dust removal pipes 11 are respectively located in the first area 101, the second area 102, and the third area. One side of each main dust removal pipe 11 is connected to one end of two bypass branch pipes 12, and the other ends of the two bypass branch pipes 12 are respectively connected to the remaining two main dust removal pipes 11. Each main dust removal pipe 11 is equipped with a control valve 21 and a fan.

[0058] Please see Figures 1 to 4 Based on the above characteristics, the operation process of the dust removal device 100 is described as follows: The first fan 31 is responsible for dust removal in the edge cleaning and dropping area, and the second fan 32 is responsible for dust removal in the main dropping area. When in use, as long as the gate valve 211 corresponding to the first fan 31 is closed and the gate valve 211 corresponding to the second fan 32 is open, and the first fan 31 and the electromagnetic pulse are turned off, the second fan 32 drives the two first pipe sections 111 to remove dust, and the dust is merged into the dust removal main pipe 11 where the second fan 32 is located.

[0059] Conversely, as long as the gate valve 211 corresponding to the second fan 32 is closed, the gate valve 211 corresponding to the first fan 31 is closed, and the second fan 32 and electromagnetic pulse are turned off, the first fan 31 drives the two first pipe sections 111 to remove dust, and the dust is merged into the dust removal main pipe 11 where the first fan 31 is located.

[0060] This utility model also proposes a float glass production line, which includes a dust removal device 100. The specific structure of the dust removal device 100 is as described in the above embodiments. Since this float glass production line adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0061] A float glass production line also includes furnaces for melting glass and conveyor rollers for transporting glass belts.

[0062] The float glass production line provided in this application cleverly utilizes a bypass branch pipe 12 to connect and merge two independently operating dust removal main pipes 11, making them mutually redundant. This allows for the activation of both the first and second fans 31 when the load is high (when all the glass sheets on the line are in place), while during normal production, only either the first or second fan 32 is activated. If either the first or second fan 32 malfunctions, the other can serve as a backup, ensuring both energy saving and safe dust removal operation. This device is simple in structure, lightweight, and very convenient to use and operate. It saves approximately 50% of electricity without affecting normal production dust removal efficiency and effectively addresses the redundancy issue of the dust removal system, demonstrating significant advantages.

[0063] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
