Description

Technical Field

[0001] The invention belongs to the technical field of industrial dust removal and relates to a full-automatic dust removal pipeline dust accumulation detection and cleaning system. Background Art

[0002] Dust removal systems are widely used in industries such as metallurgy, building materials, and chemicals to capture dust generated during production, ensuring a clean production environment and proper equipment operation. Within dust removal systems, dust is transported via pipes to dust collectors for processing. However, cleaning dust from dust collection ducts presents numerous challenges in actual operation. Due to the complex internal structure and relatively enclosed spaces of the ducts, dust easily adheres to the duct walls. As production continues, this accumulation of dust can lead to a series of serious problems. Firstly, air resistance within the ducts increases significantly, resulting in poor air flow and an inability of the dust collection system to effectively draw in and transport dust-laden air. This significantly reduces dust removal effectiveness and makes it difficult to meet the cleanliness requirements of industrial production. Secondly, to overcome this increased air resistance, the dust collection system consumes more energy to maintain normal operation, which undoubtedly increases production costs. Furthermore, cleaning dust collection ducts is complex and labor-intensive, resulting in infrequent cleaning, further exacerbating these issues. Severe duct blockage can also cause system downtime, impacting production efficiency. Therefore, developing efficient and convenient dust removal pipe cleaning technology has become a technical problem that the industry urgently needs to solve.

[0003] At present, in order to prevent the dust removal pipe from being blocked, the industry has proposed a variety of cleaning methods, but they all have certain limitations.

[0004] First, mechanical brush cleaning: This method uses a brush-equipped cleaning device to clean the inside of the pipe. This method requires the pipe to be removed and then reinstalled after cleaning. The removal and installation of the pipe requires the use of lifting equipment, which is complex and labor-intensive. The entire cleaning process is time-consuming and labor-intensive, increasing both human and material costs.

[0005] The second method is vibrating dust removal: installing a vibrating device on the outside of the pipe to vibrate and dislodge dust adhering to the inner wall of the pipe. While vibrating can loosen dust on the inner wall of the pipe to a certain extent, the vibration force may affect the pipe joints, causing them to loosen. Once loose, the dust collection pipe will experience pressure loss and dust leakage, which will not only pollute the production environment, but may also affect the overall performance of the dust collection system and even damage production equipment.

[0006] The third method is compressed air-assisted cleaning: compressed air is used to blow inside the pipe to loosen the dust and carry it away with the airflow. This method requires continuous auxiliary blowing for a long time, which undoubtedly consumes a large amount of compressed air and leads to high energy consumption. At the same time, the supply of compressed air requires the introduction of an auxiliary energy medium, which increases the complexity and operating costs of the system. In addition, this method may not be applicable to certain working environments or process requirements, and has certain limitations.

[0007] Fourth, robotic cleaning: A specially designed cleaning robot is used to clean the interior of the duct. While robotic cleaning offers advantages such as high automation and effective cleaning results, practical implementation requires careful consideration and planning of the robot access point. Without such planning, the dust collection duct will need to be dismantled, cleaned, and reinstalled. Furthermore, the high cost of purchasing and maintaining robotic equipment makes it unaffordable for some small and medium-sized enterprises.

[0008] In summary, existing dust collection duct cleaning methods have limitations in terms of ease of use, cleaning efficiency, energy consumption, and cost. Mechanical brush cleaning and robotic cleaning require frequent duct disassembly and installation, impacting production continuity; vibrating cleaning can compromise duct sealing; and compressed air cleaning consumes a lot of energy and has limited effectiveness. Therefore, there is an urgent need to develop a new dust collection duct cleaning technology to meet the demands for stable dust collection system operation in industries such as metallurgy and building materials. Summary of the Invention

[0009] In view of this, the purpose of the present invention is to provide a fully automatic dust removal pipe dust accumulation detection and cleaning system, which can automatically detect and clean dust accumulation in dust removal pipes without manual operation. It is applicable to both new and existing dust removal systems, is easy to install and maintain, and requires little operation and maintenance.

[0010] In order to achieve the above object, the present invention provides the following technical solutions:

[0011] A fully automatic dust collection pipeline dust accumulation detection and cleaning system, comprising a dust collection pipeline, a tension sensor, a maintenance box and a single-unit dust collector;

[0012] The dust removal duct consists of an inner duct and outer ducts located at both ends of the inner duct, the outer duct portion extends into the inspection box and is integrally connected to the inspection box body, the inner duct is connected to the tension sensor via a pull rope and is suspended in the inspection box, and the outer duct is inserted into the inner duct with a gap maintained;

[0013] The external pipeline is connected to the stand-alone dust collector via a pipeline;

[0014] The tension sensor is used to collect gravity data of the inner pipe and automatically calculate the dust accumulation area ratio in the inner pipe according to the gravity change. When the dust accumulation area ratio exceeds a set threshold, the stand-alone dust collector starts to suck away the dust accumulated in the dust removal pipe.

[0015] Furthermore, the upper portion of the pull rope is fixed in the maintenance box, the lower portion is fixed above the inner pipe, and the middle portion is connected to the tension sensor.

[0016] Furthermore, a first flange interface is provided at one end of the outer pipe away from the inner pipe to connect the fully automatic dust removal pipe dust accumulation detection and cleaning system to the dust removal system.

[0017] Furthermore, a second flange interface is provided on the side of the outer pipe to connect the pipe and then connect to the stand-alone dust collector.

[0018] Furthermore, a gap is provided at the interface between the inner pipe and the outer pipe, and is sealed by a soft connection to prevent dust from overflowing.

[0019] Furthermore, the maintenance box is provided with a dashboard to record data of the tension sensor.

[0020] Furthermore, the inspection box is provided with an observation window and an inspection entrance to facilitate observation and inspection and maintenance.

[0021] Furthermore, the tension sensor does not collect data during the operation of the stand-alone dust collector, and only starts collecting data when the inner pipe remains stable, so as to ensure data accuracy.

[0022] The beneficial effects of the present invention are:

[0023] 1. The present invention provides a fully automatic dust collection duct dust accumulation detection and cleaning system. Its innovative automatic detection and cleaning functions completely get rid of the dependence on manual operation. The system uses a tension sensor to monitor the dust accumulation in the dust collection duct in real time, and accurately calculates the dust accumulation area ratio based on the weight change. When the dust accumulation reaches the preset threshold, the stand-alone dust collector will automatically start to efficiently remove the dust in the duct. This design subverts traditional cleaning methods, such as manual disassembly, vibration, or the use of compressed air and other inefficient means, avoiding the problems of cumbersome operation and incomplete cleaning. Automated operation not only improves the dust removal efficiency, but also effectively prevents the increase in wind resistance and energy consumption caused by dust accumulation, ensuring the long-term stable operation of the system.

[0024] 2. The system features a modular design, with the external piping tightly integrated into the inspection box and the internal piping flexibly suspended via pull cords and tension sensors. The overall structure is compact, and installation requires no complex modifications. The external piping is equipped with standard flange interfaces, enabling quick connection to existing dust removal systems and stand-alone dust collectors for efficient operation. Furthermore, the inspection box features a built-in instrument panel, observation window, and convenient access, simplifying routine maintenance. Compared to traditional methods, this solution eliminates the need for frequent piping disassembly or additional energy, significantly reducing maintenance costs and time, making it highly practical.

[0025] 3. This technical solution is widely applicable and can seamlessly adapt to new and existing dust collection systems, providing a flexible solution to dust accumulation. For new systems, it can be directly integrated during the initial design phase, ensuring the system's inherent automated cleaning capabilities. For existing systems, simple interface adjustments are required for integration, eliminating the need for production downtime or major renovations to upgrade dust collection capabilities. Whether in metallurgy, building materials, or other industrial sectors, this solution effectively addresses the common problem of dust accumulation in dust collection ducts, ensuring a clean production environment and stable equipment operation, providing enterprises with efficient and reliable dust collection support.

[0036] Example 1

[0037] like Figures 1 to 4 As shown, this embodiment provides a fully automatic dust collection duct dust accumulation detection and cleaning system. The system includes a dust collection duct, a tension sensor 7, an inspection box 8, and a stand-alone dust collector 13. The dust collection duct consists of an inner duct 2 and an outer duct 1 located at both ends of the inner duct 2. The outer duct 1 partially extends into the inspection box 8 and is integrally connected to the inspection box 8. The inner duct 2 is connected to the tension sensor 7 via a pull rope 6 and is suspended in the inspection box 8. The outer duct 1 is inserted into the inner duct 2 with a gap maintained. The outer duct 1 is connected to the stand-alone dust collector 13 via a duct 12.

[0038] Structure and installation:

[0039] The tension sensor 7 is used to collect gravity data from the inner pipe 2. The upper end of the pull rope 6 is fixed in the inspection box 8, and the lower end is fixed above the inner pipe 2, with the tension sensor 7 connected in the middle. The pull rope 6 is made of a material with minimal elastic deformation to ensure that the tension sensor 7 can accurately measure weight.

[0040] A first flange interface 3 is provided at the end of the outer pipe 1, away from the inner pipe 2, for connecting the system to an existing dust removal system. Furthermore, a second flange interface 4 is provided on the side of the outer pipe 1, connecting to a stand-alone dust collector 13 via a pipe 12, facilitating installation and removal. To prevent dust leakage at the interface between the inner and outer pipes 2 and 1, a flexible connector 5 is used to seal the gap while maintaining the necessary clearance.

[0041] Inspection box 8 is equipped with a dashboard 10, which records and displays data from tension sensor 7, allowing operators to monitor dust accumulation within inner pipe 2 in real time. Inspection box 8 also features an observation window 9 and an inspection access 11. Observation window 9 facilitates daily visual inspections, while inspection access 11 provides maintenance access in the event of equipment failure.

[0042] Working principle:

[0043] When the dust removal system is operating normally, dust-laden gas passes through the inner pipe 2, and some dust will adhere to the inner wall, increasing the weight of the pipe. The tension sensor 7 regularly measures the weight of the inner pipe 2 and transmits the data to the background processing module. The module calculates the percentage of dust accumulation area in the inner pipe 2 based on the weight change. When the percentage exceeds a preset threshold (for example, 30%), the stand-alone dust collector 13 starts, and a negative pressure is generated through the pipe 12 and the gap between the outer pipe 1 and the inner pipe 2 to suck away the accumulated dust. After cleaning is completed, the stand-alone dust collector 13 stops working and the tension sensor 7 resumes monitoring. To ensure data accuracy, the tension sensor 7 only collects data when the inner pipe 2 is stationary, and does not collect data during the operation of the stand-alone dust collector 13.

[0044] Workflow:

[0045] 1. Dust-laden gas passes through the inner pipe 2, and dust is deposited on the inner wall.

[0046] 2. The tension sensor 7 regularly collects the weight data of the inner pipe 2 and sends it to the background module.

[0047] 3. The module calculates the dust accumulation area ratio based on the weight change.

[0048] 4. If the proportion exceeds a threshold (e.g. 30%), the stand-alone dust collector 13 is activated to suck away the dust through the gaps.

[0049] 5. After cleaning is completed, the dust collector 13 stops and monitoring continues.

[0050] This embodiment realizes automatic dust accumulation detection and cleaning without human intervention, thereby improving the maintenance efficiency and convenience of the dust removal system.

[0051] Example 2

[0052] Based on Example 1, this example enhances the structure and functions of the system. Figures 1 to 4 The system retains the core components: dust removal ducts (inner duct 2 and outer duct 1), tension sensor 7, maintenance box 8 and stand-alone dust collector 13, and the connection and installation methods are the same as those in Example 1.

[0053] A key improvement of this embodiment is the installation of a vibration device (not shown) on the outer wall of the inner pipe 2 within the inspection box 8. This device, activated simultaneously with the stand-alone dust collector 13, vibrates to loosen dust adhering to the inner pipe 2, improving cleaning efficiency. The vibration device can be either electric or pneumatic, and its frequency and amplitude can be adjusted according to dust accumulation.

[0054] Working principle:

[0055] The operation process is similar to that of Example 1, but with some enhancements. The tension sensor 7 can adjust the collection frequency according to specific conditions (for example, increase the collection frequency in a high-dust environment). When the dust accumulation area exceeds a threshold (for example, 25%), the stand-alone dust collector 13 and the vibration device are started at the same time. The stand-alone dust collector 13 sucks away dust through the gap, and the vibration device helps loosen stubborn deposits, shortening the cleaning time and reducing energy consumption. After the cleaning is completed, both stop working and the tension sensor 7 resumes monitoring.

[0056] Workflow:

[0057] 1. During operation, dust accumulates on the inner pipe 2.

[0058] 2. The tension sensor 7 collects weight data at a set frequency and sends it to the background module.

[0059] 3. The module calculates the percentage of dust accumulation area.

[0060] 4. If the proportion exceeds a threshold value (eg 25%), the stand-alone dust collector 13 and the vibration device are activated.

[0061] 5. The dust collector 13 sucks away the dust, and the vibration device helps loosen the deposits.

[0062] 6. After the cleaning is completed, both stop and monitoring continues.

[0063] By integrating a vibration device, this embodiment improves cleaning efficiency and system safety, and is suitable for industrial application scenarios with higher requirements.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions, which should all be included in the scope of the claims of the present invention.
