Abstract
Description
Technical Field
[0001] This invention belongs to the field of conveyor technology, and specifically relates to a cleaning device. Background Technology
[0002] During the operation of belt conveyors, the belt and rollers often carry some material, which in power plant environments is mostly coal particles or coal dust. The presence of coal particles or dust not only easily causes environmental pollution but also affects the power transmission between the belt and rollers, causing jamming and slippage. Coal dust, in particular, is difficult to clean from the rollers and tends to accumulate due to the pressure of the belt rollers. Current technologies often involve manual cleaning of the rollers by stopping the machine, which is time-consuming, labor-intensive, and has limited effectiveness, and cannot provide real-time cleaning of the rollers. Summary of the Invention
[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention provide a cleaning device that can remove debris from rollers in real time without affecting the normal operation of the conveyor.
[0004] The cleaning device of this invention includes a support, a housing, a scraper, and a collection assembly. The housing is mounted on the support and has an inlet. The scraper is located at the inlet and is used to scrape away debris from the outer circumferential surface of the part to be cleaned and guide the debris into the housing. The collection assembly is connected to the housing and is used to collect and transfer the debris inside the housing.
[0005] This embodiment provides a cleaning device that uses a scraper and roller at the inlet of the housing to contact the parts to be cleaned. This effectively scrapes away debris attached to the outer surface and guides it into the housing. The debris is then collected and transferred by a collection component. This achieves continuous and automatic cleaning of debris on the surface of the parts to be cleaned, preventing debris from accumulating or scattering around the equipment, reducing environmental pollution and equipment wear, and improving cleaning efficiency and the cleanliness of the working environment.
[0006] In some embodiments, the scraper is made of a flexible material and is detachably connected to the inlet.
[0007] In some embodiments, the component to be cleaned is disposed on the bracket, the scraper extends axially along the component to be cleaned, and the scraper can contact the outer peripheral surface of the component to be cleaned.
[0008] In some embodiments, the scraper includes a plurality of support members arranged at axial intervals along the part to be cleaned. Each support member includes a mounting groove and a rolling member. The mounting groove is disposed on the scraper, and the rolling member is disposed within the mounting groove. The rolling member is used to roll into contact with the outer peripheral surface of the part to be cleaned to reduce friction between the scraper and the part to be cleaned.
[0009] In some embodiments, the rolling component includes at least one of balls and rollers.
[0010] In some embodiments, the collection assembly includes a pipe and a collection component. The pipe is connected to the housing and both ends of the pipe are located outside the housing. The collection component is connected to one end of the pipe, and debris inside the housing can enter the collection component through the pipe.
[0011] In some embodiments, the collection assembly further includes a fan connected to the other end of the duct, the fan being used to generate airflow to blow debris inside the housing toward the collection assembly via the duct.
[0012] In some embodiments, the pipe is located on the side of the housing away from the inlet, and the pipe penetrates the housing, with the portion of the pipe connected to the housing forming the bottom of the housing.
[0013] In some embodiments, the collecting component includes at least one of a dust collection bag and a central dust collector.
[0014] In some embodiments, the cleaning device further includes a connecting plate for connecting the housing to the bracket and for adjusting the installation position of the housing relative to the bracket.
[0015] The cleaning device of this invention features a scraper made of flexible material that extends axially along the rollers, allowing it to conform to roller surfaces of different sizes. This results in effective scraping without damaging components. Rolling components on the scraper reduce friction with the parts being cleaned, minimizing wear and extending service life. The collection assembly is connected to the housing via a pipe and, under the action of a fan, transports debris to a dust bag or central dust collector for centralized processing and transfer, preventing secondary dust generation. Furthermore, the relative position of the housing and support can be adjusted via a connecting plate to adapt to different installation scenarios, enhancing the device's applicability and adjustability. The overall solution is simple in structure, easy to maintain, time-saving, labor-saving, and allows for real-time online cleaning. Attached Figure Description

[0022] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0023] like Figures 1-4 As shown, the cleaning device of this embodiment includes a support 1, a housing 2, a scraper 3, and a collection component 4. The housing 2 is mounted on the support 1 and has an inlet 21. The scraper 3 is located at the inlet 21 and is used to scrape off debris from the outer circumferential surface of the component 5 to be cleaned and guide the debris into the housing 2. The collection component 4 is connected to the housing 2 and is used to collect and transfer debris inside the housing 2.
[0024] The cleaning device provided in this embodiment is particularly suitable for real-time cleaning of the roller surface of a belt conveyor without stopping the machine. The cleaning device includes a support 1, a housing 2, a scraper 3, and a collection assembly 4. The support 1 serves as the frame of the belt conveyor. The housing 2 is mounted on the support 1, and has an inlet 21 on the side facing the belt roller. The scraper 3 is located at the inlet 21, extending axially along the roller, and its cleaning edge maintains contact with the outer circumferential surface of the roller. The collection assembly 4 is connected to the housing 2.
[0025] During actual installation, first, install the housing 2 in a suitable position near the belt conveyor rollers. Align the inlet 21 on the housing 2 with the roller to be cleaned. Next, install the scraper 3 at the inlet 21 and finely adjust the angle and pressure of the scraper 3 to ensure that its cleaning edge makes effective contact with the outer circumference of the roller without damaging the roller surface. Additionally, the top of the housing 2 should be lower than the top of the roller to avoid affecting the belt's operation.
[0026] During operation, the belt conveyor maintains normal operation, and the rollers rotate continuously. Dust, adhering substances, and other debris attached to the roller surface are scraped off by the edge of scraper 3 as the rollers rotate and pass over it. The scraped-off debris, under the influence of gravity and a small amount of airflow, enters the housing 2 through inlet 21 for temporary storage. The collection component 4 works continuously or intermittently to transfer the accumulated debris from the housing 2 for centralized collection or treatment. This structure enables automatic and continuous cleaning of debris from the roller surface without stopping the production line, effectively preventing debris accumulation and dust diffusion, ensuring a clean environment around the equipment, reducing downtime caused by cleaning, and improving production efficiency.
[0027] In some embodiments, the scraper 3 is made of a flexible material and is detachably connected to the inlet 21.
[0028] In this embodiment, the scraper 3 is made of a flexible material, such as wear-resistant rubber, polyurethane, or other non-metallic materials with appropriate elasticity and wear resistance. The scraper 3 is detachably connected to the inlet 21 of the housing 2. Specific detachable connection methods may include, but are not limited to, bolt fastening (preferably countersunk bolts), snap-fit connection, or slot engagement.
[0029] By employing a flexible scraper 3, it can better conform to the roller surface when in contact, avoiding hard scratches on the roller surface. It can also adapt to any unevenness on the roller surface, ensuring uniform scraping effect. Designing scraper 3 as a detachable connection facilitates individual replacement after wear, without disassembling or replacing the entire housing 2. This significantly reduces maintenance costs and the complexity of replacement operations, benefiting the long-term use and maintenance of the device.
[0030] In some embodiments, the component 5 to be cleaned is disposed on the bracket 1, and the scraper 3 extends along the axial direction of the component 5 to be cleaned, and the scraper 3 can contact the outer peripheral surface of the component 5 to be cleaned.
[0031] In this embodiment, the component to be cleaned 5 is the roller of the belt conveyor. The scraper 3 extends along the axial direction of the roller, and its length is sufficient to cover the entire width of the surface of the roller to be cleaned. During installation, the position and orientation of the scraper 3 are adjusted so that its cleaning edge can maintain stable contact with the outer circumferential surface of the roller.
[0032] In some embodiments, the scraper 3 includes a plurality of support members arranged at intervals along the axial direction of the component 5 to be cleaned. The support members include a mounting groove 31 and a rolling member 32. The mounting groove 31 is disposed on the scraper 3, and the rolling member 32 is disposed in the mounting groove 31. The rolling member 32 is used to roll in contact with the outer peripheral surface of the component 5 to reduce friction between the scraper 3 and the component 5 to be cleaned.
[0033] In this embodiment, the scraper 3 includes multiple support components, which are arranged at intervals along the axial direction of the roller to be cleaned. Each support component is provided with a mounting groove 31, and a rolling component 32 is disposed in the mounting groove 31. When the scraper 3 is installed in place, the rolling component 32 forms rolling contact with the outer peripheral surface of the roller.
[0034] By setting multiple axially spaced support components and their internal rolling components 32, the large-area sliding friction between the scraper 3 and the roller surface is transformed into rolling friction with multiple points or lines of contact. This design significantly reduces the frictional resistance and wear rate of the scraper 3 during long-term continuous operation, not only reducing the additional energy consumption required to drive the roller rotation but also effectively extending the service life of the scraper 3 itself. At the same time, the rolling contact helps maintain a stable and uniform contact pressure between the scraper 3 and the roller surface, avoiding a decrease in cleaning effect or component vibration caused by uneven sliding friction, and ensuring continuous, efficient, stable, and reliable cleaning operations even when the belt conveyor is running continuously for extended periods.
[0035] In some embodiments, the rolling component 32 includes at least one of balls and rollers.
[0036] In this embodiment, the rolling component 32 disposed in the mounting groove 31 of the scraper 3 support component can be at least one of ball bearings and rollers. For example, multiple independent ball bearings can be arranged in parallel, or one or more short rollers arranged in parallel can be used.
[0037] When ball bearings are used, they form point contact with the roller surface, providing multi-directional rolling flexibility and better adapting to minor axial movement or vibration that may occur during roller operation, maintaining smooth contact. When rollers are used, they form line contact with the roller surface, providing a larger support area and guiding properties, suitable for applications with heavier cleaning loads or requiring more stable support. Designers can flexibly select the specific type of rolling component 32, or even combine them, according to different requirements for frictional resistance, wear resistance, load-bearing capacity, and cost in actual application scenarios, thereby optimizing the performance and applicability of the cleaning device. This design further enhances the modularity and customizability of the device, enabling it to adapt to a wider range of industrial cleaning needs.
[0038] In some embodiments, the collection component 4 includes a pipe 41 and a collection part 42. The pipe 41 is connected to the housing 2, and both ends of the pipe 41 are located outside the housing 2. The collection part 42 is connected to one end of the pipe 41, and debris inside the housing 2 can enter the collection part 42 through the pipe 41.
[0039] In this embodiment, the collection component 4 specifically includes a pipe 41 and a collection part 42. One end of the pipe 41 is connected to the inside of the housing 2, and the other end and the middle section of the pipe 41 itself are located outside the housing 2. The collection part 42 (e.g., a dust bag or a dust collection box) is connected to the other end of the pipe 41.
[0040] By establishing a dedicated pipe 41 connected to the housing 2, a directional, enclosed transfer channel is provided for the debris temporarily stored inside the housing 2. Under the influence of gravity or driven by any subsequent airflow, the debris can be transported from inside the housing 2 to an externally located collection component 42 via this pipe 41. The advantages are twofold: firstly, the collection component 42 (such as a dust bag) can be placed in a more convenient, spacious, or safer location without needing to be adjacent to the equipment; secondly, the enclosed pipe 41 effectively prevents secondary leakage or dust generation during debris transfer, maintaining a clean environment around the equipment. This design makes debris collection and processing more centralized and efficient, reduces the frequency of manual cleaning of the housing 2, and improves the automation level and continuous operation capability of the entire cleaning system.
[0041] In some embodiments, the collection component 4 further includes a fan 43 connected to the other end of the pipe 41. The fan 43 is used to generate airflow to blow debris in the housing 2 through the pipe 41 toward the collection component 42.
[0042] In this embodiment, the collection component 4 also includes a fan 43. The fan 43 is connected to the other end of the pipe 41 (i.e., the other end opposite to the connection to the collection component 42). When the fan 43 is started, it can generate a directional airflow. This airflow enters from the end of the pipe 41 connected to the fan 43, flows through the pipe 41, and enters the collection section.
[0043] Its working principle and beneficial effects are as follows: The airflow generated by the fan 43 acts as an active conveying force, effectively "blowing" or "sucking" up the dust, debris, and other light impurities accumulated inside the housing 2, and causing them to move rapidly and directionally along the pipe 41 with the airflow, eventually entering the collection component 42 far from the cleaning point. It is suitable for removing dry, fine dust and effectively prevents such impurities from accumulating and hardening inside the housing 2 or pipe 41. The fan 43 can operate intermittently or continuously. When operating continuously, the continuous airflow also helps maintain air circulation inside the housing 2 and in the scraper 3 area, inhibiting dust dispersion and settling in critical parts of the equipment.
[0044] Additionally, when cleaning is required, accessories at the end of pipe 41, such as dust collection bags and fans 43, can be appropriately removed, allowing water pipes to be used directly to clean pipe 41, thus preventing debris from adhering inside the housing 2.
[0045] In some embodiments, the pipe 41 is located on the side of the housing 2 away from the inlet 21, and the pipe 41 penetrates the housing 2, with the portion of the pipe 41 connected to the housing 2 forming the bottom 22 of the housing 2.
[0046] In this embodiment, the pipe 41 is specifically located on the side of the housing 2 away from its inlet 21. The pipe 41 extends laterally through the housing 2, meaning that the middle portion of the pipe 41 passes through the internal space of the housing 2. In particular, the sidewall of this section of the pipe 41 that passes through the housing 2 forms the bottom 22 of the housing 2.
[0047] This design brings multiple benefits: First, the pipe 41 not only serves as a conveying channel but also directly acts as the structural bottom 22 of the housing 2, making the entire device structure more compact. Second, debris falling into the housing 2 from the scraper 3 naturally falls to the bottom 22 formed by the pipe 41 under gravity, and then enters the conveying channel, effectively avoiding the residue and accumulation of debris in the traditional flat-bottomed housing 2. Third, since the bottom 22, i.e., the pipe 41, usually has a relatively smooth inner wall, it is very conducive to the movement of debris towards the collection component 42 under the action of gravity or airflow, further improving the efficiency and thoroughness of debris removal. In addition, the side plate where the scraper is installed in the housing 3 is arranged at an angle and connected to the pipe 41 forming the bottom 22, allowing dust entering the housing 2 to slide directly into the pipe 41.
[0048] In some embodiments, the collecting component 42 includes at least one of a dust collection bag and a central dust collector.
[0049] In this embodiment, the collecting component 42 in the collecting assembly 4 can specifically be at least one of a dust collection bag and a central dust collector. Alternatively, it can be other types of dust collectors, such as cyclone separators, electrostatic precipitators, bag filters, etc.
[0050] Using dust collection bags is a low-cost and flexible end-point collection method. Dust collection bags are typically made of filter material that traps debris carried by the airflow, while the purified air is discharged. Their advantages include ease of disassembly, emptying, and replacement, making them suitable for applications with relatively small cleaning volumes or those requiring decentralized collection.
[0051] Using a central dust collector means connecting the pipe 41 of this cleaning device to the factory's existing centralized dust collection system. This method is suitable for large-scale, continuous production conditions, enabling the unified collection and centralized treatment of dust generated from multiple cleaning points. It has high processing efficiency and is conducive to the further resource utilization of dust.
[0052] In some embodiments, the cleaning device further includes a connecting plate 6, which is used to connect the housing 2 and the bracket 1 and can adjust the installation position of the housing 2 relative to the bracket 1.
[0053] In this embodiment, the cleaning device also includes a connecting plate 6. The connecting plate 6 is used to connect the housing 2 and the bracket 1, and its structural design allows the installation position of the housing 2 relative to the bracket 1 to be flexibly adjusted.
[0054] Specifically, the connecting plate 6 can be installed in an adjustable manner, for example, by setting elongated holes or grooves on the connecting plate 6 or the bracket 1 and fastening it with bolts; or by using a hinged connection with positioning pin holes. The housing 2 is fixed or connected to the connecting plate 6. By changing the relative fixed position between the connecting plate 6 and the bracket 1, the spatial position of the housing 2 (together with the inlet 21 and scraper 3 on it) relative to the rollers can be adjusted indirectly and precisely.
[0055] The significant advantage of setting the connecting plate 6 is that, in actual installation, due to manufacturing tolerances, frame deformation after long-term operation, or differences in the size of different roller models, the actual position of the rollers may not be entirely ideal. Through the adjustment function of the connecting plate 6, installers can easily and finely adjust the front-to-back, left-to-right, and even angle of the housing 2 and the scraper 3, ensuring that the scraper 3 can contact the roller surface with the optimal posture and pressure, thereby achieving the best cleaning effect, while avoiding excessive wear or incomplete cleaning due to misalignment.
