Description

Technical Field

[0001] This utility model relates to the field of dust collection technology for broken glass conveyor belts, and more specifically, to an energy-saving and redundant system for a broken glass conveyor belt dust collector. Background Technology

[0002] In the glass production process, raw materials typically consist of a certain proportion of crushed glass and raw material mixtures. These materials need to be transported to the feeding hopper at the head of the glass kiln via a belt conveyor system, and then fed into the kiln for melting to ultimately complete glass production. During the transportation of raw materials, due to the movement and drop of materials, a large amount of dust is inevitably generated near the belt conveyor system. This dust not only affects the working environment and worker health, but may also lead to equipment wear and malfunctions. Therefore, glass manufacturing companies generally design and install dust collection devices in their conveyor belt systems to reduce dust emissions. Currently, the most commonly used system is the electric fan bag filter dust collector system.

[0003] According to the requirements of glass production processes, it takes approximately 5-7 minutes to prepare one set of crushed glass and mixed materials, and about 150 sets are needed per day. This means that the belt conveyor system needs to operate for at least 20 hours a day, and the dust collection system must operate continuously in conjunction with the belt conveyor. In glass manufacturing enterprises, there are two main dust collection methods: electric fan baghouse dust collectors and water spray dust collectors. Electric fan baghouse dust collectors have a wide range of applications and can be used in various situations; while water spray dust collectors are limited by water resources and have relatively fewer applications. Therefore, most belt conveyor systems use electric fan baghouse dust collectors as the primary dust collection method. However, in the process of conveying crushed glass, due to the characteristics of crushed glass, both water spray and baghouse dust collection systems are suitable, but traditional water spray systems suffer from low water resource utilization efficiency.

[0004] Existing technologies for conveyor belt systems handling broken glass, whether employing electric-driven fan bag filters or water spray dust collection, have significant drawbacks. Firstly, electric-driven fan bag filters require continuous operation for extended periods, resulting in high energy consumption. Secondly, while water spray dust collection systems have relatively lower energy consumption, traditional systems suffer from high water consumption and water waste. More critically, these systems are typically single-system designs; if a system malfunctions or requires maintenance, the dust collection function is completely interrupted, leading to dust pollution and impacting the production environment and working conditions. Furthermore, the lack of a backup system makes it difficult to guarantee continuous production during equipment maintenance and repairs, reducing production efficiency. Therefore, how to reduce energy and water consumption while ensuring effective dust collection and improving system reliability has become an urgent technical challenge. Utility Model Content

[0005] To overcome the aforementioned shortcomings of existing technologies, this utility model provides an energy-saving redundant system for a glass crushing belt dust collector. Based on the characteristics of two suitable dust collection systems for glass crushing belts, a spray dust collection system is added to the original electric-driven dust collector system. The two systems are redundant to improve dust collection stability. The water used for spray dust collection is recycled water from waste heat power generation in the glass factory, achieving sustainable water resource utilization. Daily operation primarily uses water spraying, with the electric-driven fan dust collector as a backup, ultimately achieving the goals of energy saving and improved dust collection stability of the original system.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An energy-saving and redundant system for a broken glass belt dust collector includes a broken glass belt single dust collector system, wherein the broken glass single dust collector system includes a broken glass feeding hopper (1), a gate valve one (2), a feeding feeder (3), a chute one (4), a broken glass weighing hopper (5), a feeding feeder (6), a chute two (7), a gate valve two (8), a bag filter (9), and a broken glass belt (10).

[0008] As a further solution of this utility model, an automatic water spray dust removal system is added to the original single dust collector system for broken glass belts. The automatic water spray dust removal system includes: a concentrated water recovery tank (11) for collecting concentrated water discharged from the waste heat power plant; a water pump (14) connected to the concentrated water recovery tank (11) for pressurizing and conveying concentrated water; a solenoid valve (12) connected to the outlet pipe of the water pump (14) for controlling the start and stop of the water spray system; and a spray head (13) installed in the chute (4) of the feeding machine (3) and connected to the solenoid valve (12) through a pipe. The water spray dust removal system and the original bag filter dust removal system are redundant.

[0009] As a further embodiment of this utility model, the concentrated water recovery tank (11) is also connected to the desulfurization mixer via a pipeline, so that the concentrated water can be used for both spray dust removal and desulfurization system.

[0010] As a further embodiment of this utility model, the bag dust removal system includes the bag dust collector (9), the dust removal induced draft fan (15), and the second gate valve (8), wherein the second gate valve (8) is installed on the pipe connected to the bag dust collector (9) and is used to control the airflow of the dust removal system.

[0011] As a further embodiment of this utility model, the system normally operates in water spray dust removal mode, and switches to bag filter dust removal system when the water supply is unstable.

[0012] As a further embodiment of the present invention, the spraying range of the spray head (13) covers the area where the broken glass falls within the chute (4).

[0013] As a further embodiment of this invention, the broken glass is first stored in the broken glass feeding hopper (1), and the feeding amount is controlled by the gate valve (2). After feeding, the broken glass is transported to the chute (4) by the feeding feeder (3). In the chute (4), a spray head (13) is installed for water spraying and dust removal. The spraying water comes from the concentrated water recovery tank (11), which is concentrated water recovered from the waste heat power plant. After being pressurized by the feed water pump (14), it is sent to the spraying system and the desulfurization mixer.

[0014] The spray water flow is controlled by a solenoid valve (12). When the solenoid valve (12) is open, the concentrated water is pressurized by the feed pump (14) and flows to the spray head (13), spraying in the first chute (4) to suppress dust. The broken glass falls from the first chute (4) into the broken glass weighing bin (5) for weighing. After weighing, the broken glass is transported to the second chute (7) by the feeder (6).

[0015] Broken glass falls from chute 2 (7) onto the broken glass conveyor belt (10) for transport. Throughout the transport process, the system employs a dual dust removal method: water spray dust removal and a bag filter (9) combined with a dust removal fan (15) for dry dust removal. These two systems are redundant; normally, water spray is the primary method to save energy and reduce consumption. When the water supply is unstable, the system can switch to bag filter dust removal to ensure that the dust removal effect is not affected.

[0016] The second gate valve (8) controls the airflow channel of the dust removal system, which can adjust the dust removal efficiency or isolate the dust removal system when needed. The dust removal fan (15) of the bag filter (9) is responsible for generating negative pressure to draw dust into the bag filter for filtration.

[0017] The entire system realizes the recycling of water resources. The concentrated water discharged from the waste heat power plant is collected by the concentrated water recovery tank (11) and used for both the spraying of the belt dust collector and the supply of the desulfurization system to the desulfurization mixer, thereby improving the efficiency of resource utilization and achieving the purpose of energy conservation and environmental protection.

[0018] Compared with the prior art, the beneficial effects of the energy-saving and redundant system of the broken glass belt dust collector of this utility model are as follows:

[0019] This invention provides an energy-saving and redundant system for a broken glass belt dust collector. Based on the existing baghouse dust collector system, an automatic water spray system is added. Concentrated water from a waste heat power plant is sprayed into the chute through a concentrated water recovery tank, a feed pump, solenoid valves, and spray heads, covering the area where broken glass falls. The concentrated water is also used to supply the desulfurization mixer. The water spray and baghouse dust collector are redundant; the energy-saving water spray is the primary system in normal operation, switching to baghouse dust collector when the water supply is unstable. Existing technologies rely on a single electrically driven fan for baghouse dust collection or water spray, resulting in high energy and water consumption, and the potential for dust pollution from single-system failures. This invention significantly reduces energy and water consumption, improves system stability and environmental friendliness, and optimizes the shortcomings of existing technologies through a dual-system design and water resource recycling.

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Example 1

[0025] like Figure 1 The diagram shows a single dust collector system for broken glass. The single dust collector system for broken glass includes a broken glass feeding hopper (1), a gate valve (2), a feeding feeder (3), a chute (4), a broken glass weighing hopper (5), a feeding feeder (6), a chute (7), a gate valve (8), a bag filter (9), and a broken glass conveyor belt (10).

[0026] The process of the single dust collector system for crushed glass is as follows: First, crushed glass enters the crushed glass feeding hopper (1), and the flow rate is controlled by the gate valve (2). Then, the feeding feeder (3) transports the material to the chute (4). The material enters the crushed glass weighing hopper (5) through the chute (4) for weighing. After weighing, the material is controlled by the feeding feeder (6) to fall to the chute (7), and then onto the crushed glass conveyor belt (10). The gate valve (8) connects the bag filter (9) and the main body of the system to control the start and stop of the dust removal system. The bag filter (9) is connected to each dust-generating point through pipelines and is responsible for collecting the dust generated in each link of the system. Finally, the crushed glass conveyor belt (10) transports the material to the original melting belt direction and finally sends it to the furnace for glass production. This dust removal system needs to operate synchronously with the belt conveyor system to ensure that the dust in the glass factory production process is effectively controlled.

[0027] like Figure 2 The diagram shown is a schematic of an automatic water spraying system. The automatic water spraying system includes a broken glass feeding bin (1), a slide valve (2), a feeding machine (3), a chute (4), a concentrated water recovery tank (11), a desulfurization mixer, a solenoid valve (12), and a spray head (13).

[0028] The broken glass is first stored in the broken glass feeding hopper (1), and the feeding is controlled by the gate valve (2). Then, the broken glass is transported to the chute (4) by the feeding feeder (3). Spray heads (13) are installed in the chute (4) for water spray dust removal. The bag filter (9) is connected to the system through pipes for conventional dry dust removal. The concentrate recovery tank (11) collects the concentrate discharged from the waste heat power plant. This water is used to supply the desulfurization system to the desulfurization mixer and is also supplied to the spray system through branch pipes. The solenoid valve (12) controls the start and stop of the water spray system. When started, the concentrate flows from the concentrate recovery tank (11) through the solenoid valve (12) to the spray head (13) and is sprayed for dust removal in the chute (4).

[0029] The energy-saving redundant system for the broken glass belt dust collector in this embodiment adds an automatic water spray dust collection system to the original bag filter dust collection system for the broken glass belt. The two systems can then be used redundantly. Since the water spray uses concentrated wastewater from a waste heat power plant for recycling, and the original design reused this water for the desulfurization system, the water usage for spraying is small and will not affect the desulfurization water supply. Therefore, simply adding a branch pipe to this water supply pipeline and using a solenoid valve to control the spray start can achieve environmentally friendly spray dust collection. The induced draft fan for the bag filter dust collector needs to be electrically driven, so water spraying is the primary method during normal operation, achieving energy saving and consumption reduction. In case of unstable water supply, the system can be switched to bag filter dust collection without affecting the dust collection effect.

[0030] The energy-saving and redundant system of the glass crushing belt dust collector in this embodiment includes a glass crushing belt single dust collector system and an automatic water spray dust collection system. The glass crushing belt single dust collector system includes a glass crushing hopper (1), a gate valve (2), a feeding machine (3), a chute (4), a glass crushing weighing hopper (5), a feeding machine (6), a chute (7), a gate valve (8), a bag filter (9), and a glass crushing belt (10). The automatic water spray dust collection system includes a concentrated water recovery tank. (11) is used to collect concentrated water discharged from the waste heat power plant; a water pump (14) is connected to the concentrated water recovery tank (11) and is used to pressurize and transport concentrated water; a solenoid valve (12) is connected to the outlet pipe of the water pump (14) and is used to control the start and stop of the water spray system; a spray head (13) is installed in the chute (4) of the feeding machine (3) and is connected to the solenoid valve (12) through a pipe; wherein, the water spray dust removal system and the original bag dust removal system are used redundantly.

[0031] The concentrated water recovery tank (11) in this embodiment of the present invention is also connected to the desulfurization mixer through a pipeline, so that the concentrated water can be used for both spray dust removal and desulfurization system.

[0032] The system described in this embodiment of the utility model mainly operates in the mode of water spray dust removal, and switches to bag filter dust removal system when the water supply is unstable.

[0033] The spray range of the spray head (13) in this embodiment of the present invention covers the falling area of ​​the broken glass in the chute (4).

[0034] Example 2

[0035] The working process of an energy-saving redundant system for a broken glass belt dust collector includes:

[0036] In this embodiment of the invention, the broken glass is first stored in the broken glass feeding hopper (1), and the feeding amount is controlled by the gate valve (2). After feeding, the broken glass is transported to the chute (4) by the feeding feeder (3). In the chute (4), a spray head (13) is installed for water spraying and dust removal. The spraying water comes from the concentrated water recovery tank (11), which is concentrated water recovered from the waste heat power plant. After being pressurized by the feed water pump (14), it is sent to the spraying system and the desulfurization mixer.

[0037] In this embodiment of the invention, the spray water flow is controlled by a solenoid valve (12). When the solenoid valve (12) is opened, the concentrated water is pressurized by the water pump (14) and flows to the spray head (13), spraying in the first chute (4) to suppress dust. The broken glass falls from the first chute (4) into the broken glass weighing bin (5) for weighing. After weighing, the broken glass is transported to the second chute (7) by the feeding machine (6).

[0038] In this embodiment of the invention, broken glass falls from chute two (7) onto the broken glass conveyor belt (10) for conveying. Throughout the conveying process, the system employs a dual dust removal method: one is water spray dust removal, and the other is dry dust removal using a bag filter (9) in conjunction with a dust removal fan (15). These two systems are redundant; normally, water spray is the primary method to save energy and reduce consumption, but when the water supply is unstable, it can be switched to bag filter dust removal to ensure that the dust removal effect is not affected.

[0039] In this embodiment of the invention, the second gate valve (8) controls the airflow channel of the dust removal system, which can adjust the dust removal efficiency or isolate the dust removal system when needed. The dust removal fan (15) of the bag filter (9) is responsible for generating negative pressure to draw dust into the bag filter for filtration.

[0040] The energy-saving redundant system of the broken glass belt dust collector in this embodiment realizes the recycling of water resources. The concentrated water discharged from the waste heat power plant is collected by the concentrated water recovery tank (11) and used for both belt dust collection spraying and desulfurization mixing to supply the desulfurization system, thereby improving resource utilization efficiency and achieving the purpose of energy saving and environmental protection.
