Description

Technical Field

[0001] This invention relates to the field of color sorting equipment technology, and in particular to a color sorter collaborative dust removal system suitable for cloud control systems. Background Technology

[0002] When color sorters separate granular materials, the materials typically fall along a predetermined path, and during the sorting process, discolored or substandard particles are blown away from the main feed stream by airflow. During this process, dust contained in the material is easily stirred up by the airflow, especially when processing materials with high dust content. The dust will form a dispersed state inside the equipment and spread to various areas under the influence of the airflow.

[0003] In existing technologies, color sorters are typically equipped with a dust suction structure to clean up the dust generated during the sorting process using negative pressure suction. However, in practical applications, different materials contain dust of varying types and characteristics. For example, some dust consists of smooth, fine particles, while others are fluffy and have strong adsorption properties. Especially when processing materials with high dust content and strong adhesion, such as oats, existing dust suction structures struggle to remove the dust promptly and effectively.

[0004] The airflow generated during the sorting process carries dust to the vicinity of the observation window. Some dust adheres directly to the surface of the observation window, while the remaining dust flows towards the observation window under the influence of the airflow pressure difference within the receiving chamber, further exacerbating dust accumulation on the observation window surface. As the equipment operates for longer periods, the amount of dust adhering to the observation window gradually increases, reducing its light transmittance and affecting image acquisition quality. This, in turn, negatively impacts the sorting accuracy and output of the color sorter. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a color sorter collaborative dust removal system suitable for cloud control systems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A color sorter collaborative dust removal system suitable for cloud control systems includes a color sorter with an observation window and a receiving chamber, as well as an upper dust blowing structure and a lower dust suction structure. The upper dust blowing structure is used to deliver airflow to the surface of the observation window for cleaning. The lower dust suction structure includes a dust suction chamber on the color sorter. The dust suction chamber has several first dust suction holes and several second dust suction holes on its side and bottom inside the receiving chamber, respectively. A first dust filter plate is provided at the opening of the first dust suction hole, and a second dust filter plate is provided at the opening of the second dust suction hole. The second dust filter plates are inclined. The outer wall of the dust suction chamber is provided with a suction interface and a suction elbow. The ends of the suction interface and the suction elbow away from the dust suction chamber are respectively connected to a negative pressure source.

[0008] It also includes a control module and a communication module. The control module is connected to the fan, the negative pressure source and the communication module respectively. The communication module is used to communicate with the cloud control platform. The control module adjusts the blowing airflow of the fan and the suction intensity of the negative pressure source according to the dust removal control parameters and / or color sorter operating status information issued by the cloud control platform, so that the upper dust blowing structure and the lower dust suction structure maintain a coordinated dust removal state under different dust conditions.

[0009] Preferably, the interior of the dust collection chamber includes a central dust collection chamber located in the middle of the dust collection chamber, and two end dust collection chambers located at both ends of the dust collection chamber. The central dust collection chamber and the two end dust collection chambers are not connected to each other. The suction inlet is located in the central dust collection chamber, and the suction elbow is located at both ends of the outer wall of the dust collection chamber.

[0010] Preferably, side baffles are provided on both sides of the second dust filter plate. The top of the side baffles abuts against the bottom outer wall of the dust collection chamber. The side baffles block both sides of the gap between the second dust filter plate and the second dust collection hole, preventing the sucked material from sliding off the sides of the second dust filter plate, ensuring that the sucked material is effectively guided by the second dust filter plate, and also preventing it from being directly sucked into the dust collection chamber without being filtered by the second dust filter plate.

[0011] Preferably, the dust blowing structure includes a fan installed on the color sorter, the air outlet of the fan is provided with a blower pipe, and the end of the blower pipe away from the fan is provided with a blower distributor.

[0012] Preferably, the blower distributor includes a distribution housing mounted on the color sorter, and the distribution housing is provided with an air inlet and an air outlet.

[0013] Preferably, the air outlet is a flat, narrow slit-shaped opening, and its extension direction corresponds to the surface of the observation window, so that the airflow blown out by the air outlet can cover and sweep the surface of the observation window.

[0014] Preferably, the evenly distributed housing is provided with an evenly distributed partition plate to divide the airflow entering from the air inlet so that the airflow is evenly output from the air outlet.

[0015] Preferably, the outer wall of the dust collection chamber is provided with several cleaning covers, which can be opened to clean the second dust filter and the first dust filter.

[0016] The beneficial effects of this invention are as follows:

[0017] This invention utilizes an upper dust-blowing structure and a lower dust-suction structure on a color sorter, allowing the cleaning of the observation window surface and the extraction of dust from the receiving chamber to occur simultaneously. The upper dust-blowing structure blows away dust adhering to the observation window surface, while the lower dust-suction structure uses negative pressure to extract dust from the receiving chamber and discharge it outside the equipment, thus forming a synergistic dust removal mechanism. Compared to existing structures that rely solely on a single dust-suction method, this invention effectively reduces dust adhesion to the observation window surface, ensures the light transmittance of the observation window, improves the sorting accuracy and operational stability of the color sorter, and also helps increase the output of the equipment when handling high-dust materials.

[0018] By setting up a partition plate inside the blower and designing the air outlet as a flat, narrow slit, the airflow is evenly covered on the surface of the observation window in a sheet-like form, avoiding the problem of localized airflow concentration or uneven distribution. This achieves comprehensive blowing of the observation window, improves the dust removal effect, reduces the possibility of dust re-adhesion, and further enhances dust removal efficiency.

[0019] By setting several first and second suction holes on the side walls and bottom of the suction chamber, dust from different locations in the receiving chamber can be sucked up through multiple paths. At the same time, the structure of the middle suction chamber and the two end suction chambers being unconnected creates a relatively independent negative pressure environment in each area, avoiding airflow interference and thus improving suction uniformity and overall dust removal efficiency.

[0020] By setting the second dust filter screen to an inclined structure and combining it with the non-complete engagement relationship between it and the dust collection chamber, the sucked-in material that enters the dust collection chamber but is not carried away by the airflow can fall back onto the second dust filter screen under its own weight and be guided back into the receiving chamber. This achieves the recycling of fine particulate material, which not only avoids material loss but also prevents material from accumulating in the dust collection chamber and affecting the dust collection effect.

[0021] By setting side baffles on both sides of the second dust filter plate, the sides of the second dust filter plate are blocked, so that the sucked material slides down along a predetermined path and avoids scattering from the side. At the same time, it reduces the situation where unfiltered particulate material directly enters the dust suction chamber from the side, thereby improving the material guiding stability and filtration effect.

[0022] By rationally designing the mesh size of the first and second dust filter plates, the system can achieve a balance between dust removal efficiency and material recovery effect while ensuring smooth airflow and preventing clogging. In conjunction with the airflow guiding effect of the second dust filter plate, the system can improve the reliability and stability of its operation.

[0023] By setting up control and communication modules, the dust removal system can be connected to the cloud control platform. The cloud control platform can issue dust removal control parameters based on material type, equipment output, dust concentration, or historical operating data. The control module can then adjust the fan and negative pressure source in a coordinated manner. This allows the upper dust blowing structure and the lower dust suction structure to no longer operate under fixed conditions, but to adaptively and collaboratively remove dust based on the actual dust load, thereby improving the operational stability of the color sorter under remote centralized management and continuous production conditions.

Detailed Implementation

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] Reference Figures 1 to 9 A color sorter-coordinated dust removal system suitable for cloud control systems includes a color sorter 1, which has an observation window 7 and a receiving chamber 12. The observation window 7 is used for image acquisition devices to image and identify falling materials, and the receiving chamber 12 is located below the observation window 7 to receive the sorted materials and the dust generated during the sorting process.

[0036] The dust removal system of the color sorter also includes an upper dust blowing structure 14 and a lower dust suction structure 15. The upper dust blowing structure 14 is located above or near the observation window 7 and is used to deliver airflow to the surface of the observation window 7 to blow away the dust adhering to the surface of the observation window 7, so that the dust is removed from the surface of the observation window 7 and enters the receiving chamber 12, thereby avoiding dust adhesion from affecting the light transmittance and image acquisition effect of the observation window 7.

[0037] The lower suction structure 15 includes a suction chamber 6 mounted on the color sorter 1. The suction chamber 6 is located within the receiving chamber 12, preferably in the side and bottom areas of the receiving chamber 12, and is used for negative pressure suction of dust and some fine particulate matter within the receiving chamber 12. Several first suction holes 10 and several second suction holes 11 are respectively provided on the side and bottom of the suction chamber 6 within the receiving chamber 12, for suction of suspended or laterally flowing dust and particulate matter within the receiving chamber 12, thereby forming a multi-directional suction path within the receiving chamber 12 and improving overall dust removal efficiency.

[0038] A first dust filter plate 17 is provided at the opening of the first dust suction hole 10 to block particulate materials entering the dust suction chamber 6, so that dust can pass through while larger particulate materials are intercepted, thereby preventing larger particulate materials from entering the dust suction chamber 6 and affecting the dust suction effect or causing blockage.

[0039] A second dust filter plate 16 is provided at the opening of the second suction hole 11, and the second dust filter plate 16 is inclined. By arranging the second dust filter plate 16 at an inclination, it not only has the function of blocking particulate materials, but also can be used as a flow guide component. In actual operation, some of the sucked-in material 18 that enters the suction chamber 6 is not carried away by the airflow due to its own weight or less influence from the airflow. At this time, this part of the sucked-in material 18 will fall back onto the second dust filter plate 16 under its own weight, and slide along the inclined direction of the second dust filter plate 16 under the action of gravity, thereby guiding it back into the receiving chamber 12, realizing the recovery of the accidentally sucked-in particulate materials, avoiding material loss, and preventing particulate materials from accumulating in the suction chamber 6.

[0040] The outer wall of the dust collection chamber 6 is provided with a suction port 4 and a suction elbow 5. The ends of the suction port 4 and the suction elbow 5 away from the dust collection chamber 6 are respectively connected to a negative pressure source. Through the action of the negative pressure source, a negative pressure environment is formed inside the dust collection chamber 6, so that the dust and some fine particulate matter in the receiving chamber 12 are sucked into the dust collection chamber 6 through the first suction hole 10 and the second suction hole 11, and finally discharged to the outside of the equipment through the suction port 4 and the suction elbow 5, thereby realizing the continuous suction and discharge of dust.

[0041] In this embodiment, the mesh size of the first dust filter plate 17 and the second dust filter plate 16 is designed according to the actual dust removal requirements. Considering that if the mesh size is set too small, it is easy to be clogged by dust during long-term use, thereby affecting the dust collection effect, the mesh size of the first dust filter plate 17 and the second dust filter plate 16 in this embodiment is not set too small, so as to ensure smooth airflow while taking into account a certain filtration capacity.

[0042] Under the aforementioned mesh size design, some smaller particles will be drawn into the suction chamber 6 along with dust through the first suction hole 10 or the second suction hole 11 under the action of negative pressure airflow, forming sucked-in material 18. Since this part of sucked-in material 18 has a small particle size and a limited number, it is allowed to enter the suction chamber 6 without affecting the overall dust removal effect.

[0043] To prevent the sucked-in material 18 from accumulating in the suction chamber 6 or being directly discharged, causing material loss, the second dust filter plate 16 is inclined on one side of the bottom of the suction chamber 6, and the second dust filter plate 16 and the second suction hole 11 located at the bottom of the suction chamber 6 do not form a completely sealed or fully engaged relationship. This structural arrangement allows the second dust filter plate 16 to still provide a certain degree of filtration and guidance for the airflow entering the suction chamber 6 without affecting the normal suction function of the first suction hole 10.

[0044] Specifically, after the airflow weakens or stops, the sucked-in material 18 entering the suction chamber 6 falls under its own weight and lands on the bottom inner wall of the suction chamber 6. Then, under gravity, it slides onto the second dust filter plate 16 and is guided back into the receiving chamber 12 along the inclined direction of the second dust filter plate 16, thus achieving the recovery of the sucked-in material 18. Since the second dust filter plate 16 does not completely seal the first suction hole 10, it neither significantly weakens the suction capacity of the first suction hole 10 nor fails to provide an effective return path for the sucked-in material 18.

[0045] Through the above design, while ensuring smooth dust suction and preventing clogging, it achieves effective recovery of fine particulate materials, avoids material waste, and further improves the overall operating efficiency and dust removal stability of color sorter 1.

[0046] In a preferred embodiment of the present invention, the interior of the suction chamber 6 is configured with a partition structure, including a central suction chamber located in the middle of the suction chamber 6, and two end suction chambers located at both ends of the suction chamber 6. The central suction chamber and the two end suction chambers are structurally independent of each other and are not interconnected, thereby forming multiple independent negative pressure suction areas within the same suction chamber 6.

[0047] Specifically, the intermediate dust suction chamber is located in the central area of ​​the dust suction chamber 6, corresponding to the middle position of the receiving chamber 12, and is used for centralized suction of dust accumulated in this area; the two end dust suction chambers are respectively set at the left and right ends of the dust suction chamber 6, corresponding to the two sides of the receiving chamber 12, and are used for separate suction of dust in the two sides. Through the above-mentioned partitioning, the dust in different areas of the receiving chamber 12 can be effectively covered, thereby avoiding the problem of insufficient local suction or uneven dust removal caused by a single suction point.

[0048] The intermediate suction chamber is connected to the suction port 4, which is located on the outer wall of the suction chamber 6 and connected to a negative pressure source to create a stable negative pressure environment within the intermediate suction chamber. The two end suction chambers are respectively connected to suction elbows 5 located at both ends of the outer wall of the suction chamber 6. These suction elbows 5 are also connected to a negative pressure source to respectively suction the two end suction chambers. The distributed arrangement of the suction ports 4 and suction elbows 5 ensures that both the intermediate and end suction chambers have independent suction paths, thereby improving overall suction efficiency.

[0049] Because the middle suction chamber is not connected to the two end suction chambers, there is no airflow interference between the various suction chambers, which helps maintain a stable negative pressure state and makes the suction capacity of each area more balanced and stable. At the same time, multiple suction chambers act on different areas of the receiving chamber 12, and during the material sorting and dust raising process, dust can be simultaneously sucked up from multiple points and in different areas, thereby significantly improving the dust removal efficiency.

[0050] In a preferred embodiment of the present invention, side baffles 13 are provided on both sides of the second dust filter plate 16. The side baffles 13 are arranged along the extending direction of the second dust filter plate 16 and are located at the two side edges of the second dust filter plate 16. The top of the side baffle 13 abuts against the bottom outer wall of the suction chamber 6, so that a relatively closed lateral boundary structure is formed between the side baffle 13 and the suction chamber 6, thereby forming a restricted flow guiding area between the second dust filter plate 16 and the second suction hole 11.

[0051] With the above structural arrangement, during the process of receiving and guiding the sucked-in material 18, the side boundaries of the second dust filter plate 16 are limited by the side baffles 13. This ensures that after the sucked-in material 18 falls onto the second dust filter plate 16, it can only slide downwards along the inclined direction of the second dust filter plate 16, and is not likely to slide out from the side of the second dust filter plate 16. This effectively prevents the sucked-in material 18 from sliding off the sides of the second dust filter plate 16 to a non-predetermined path, thereby ensuring that it can be stably guided back into the receiving chamber 12.

[0052] Meanwhile, the side baffle 13 blocks both sides of the area between the second dust filter plate 16 and the second suction hole 11, forming a relatively controlled flow space in this area under the action of airflow. Dust and airflow need to pass through the mesh area when passing through the second dust filter plate 16, thereby enhancing the filtration effect and preventing some particulate matter from bypassing the dust filtration path and directly entering the suction chamber 6 from the side.

[0053] In a preferred embodiment of the present invention, the upper dust blowing structure 14 includes a fan 2 mounted on the color sorter 1. The fan 2 is preferably mounted on the upper part of the color sorter 1 or near the observation window 7 to generate a stable airflow. The air outlet of the fan 2 is connected to a blower duct 8, which is used to transport the airflow generated by the fan 2 to the area near the observation window 7.

[0054] An air distributor 9 is provided at the end of the blower duct 8 away from the blower 2. The air distributor 9 is installed on the color sorter 1 and is located above or near the observation window 7, so that its output airflow can directly act on the surface of the observation window 7. By setting the air distributor 9, the concentrated airflow from the blower duct 8 is redistributed, thereby improving the problem of uneven airflow distribution.

[0055] The air distributor 9 includes a distribution housing 92, which is a structural component with an internal cavity and an air inlet 91 and an air outlet 93. The air inlet 91 is connected to the air duct 8 and is used to receive the airflow delivered by the fan 2. After entering the distribution housing 92, the airflow flows inside the housing.

[0056] The uniformly distributed housing 92 is provided with a uniformly distributed partition plate 94, which is disposed inside the uniformly distributed housing 92 to divert the airflow entering the uniformly distributed housing 92. By setting the uniformly distributed partition plate 94, the originally concentrated airflow is dispersed to different areas within the uniformly distributed housing 92, thereby reducing local airflow velocity differences and forming a relatively uniform flow field inside the housing.

[0057] The air outlet 93 is disposed on the uniformly distributed housing 92 and communicates with the interior of the uniformly distributed housing 92. The air outlet 93 is a flat, narrow slit-shaped opening, extending along a certain direction along its length, and this extending direction corresponds to the surface of the observation window 7. By designing the air outlet 93 as a flat, narrow slit-shaped structure, the airflow ejected from the air outlet 93 forms a sheet-like airflow with a large coverage width and a relatively uniform flow velocity distribution.

[0058] In actual operation, after the blower 2 starts, it generates airflow. The airflow enters the equalization housing 92 through the blower duct 8, is evenly distributed under the diversion effect of the equalization partition plate 94, and is finally ejected in the form of sheet-like airflow through the air outlet 93. Since the extension direction of the air outlet 93 corresponds to the surface of the observation window 7, the ejected airflow can cover the entire surface area of ​​the observation window 7, continuously blowing away the dust attached to the observation window 7, causing the dust to detach from the surface of the observation window 7 and enter the receiving chamber 12.

[0059] In a preferred embodiment of the present invention, the outer wall of the suction chamber 6 is provided with a plurality of cleaning covers 3. The cleaning covers 3 are respectively disposed at positions corresponding to the second dust filter plate 16 and the first dust filter plate 17 in the suction chamber 6, and are used for maintenance and cleaning of the relevant structures inside the suction chamber 6. The cleaning covers 3 can be opened and connected to the outer wall of the suction chamber 6 by means of hinge, snap-fit ​​connection or threaded fastening, and form a relatively sealed structure with the suction chamber 6 in the closed state to avoid affecting the negative pressure environment inside the suction chamber 6.

[0060] Specifically, when maintenance is required, the cleaning cover 3 at the corresponding position can be opened to directly access the second dust filter plate 16 and the first dust filter plate 17 for cleaning or rinsing. This also removes dust adhering to the inner wall of the suction chamber 6, preventing long-term dust accumulation from affecting the smooth flow of the suction channel. After cleaning, the cleaning cover 3 is closed and secured again to restore the suction chamber 6 to a sealed state, ensuring the stability of negative pressure suction during subsequent operation.

[0061] In a preferred embodiment of the present invention, the color sorter-coordinated dust removal system further includes a control module, a communication module, a dust detection element, and a differential pressure detection element (the control module, communication module, dust detection element, and differential pressure detection element are not shown in the figures). The control module can be a PLC controller, a microcontroller controller, or an industrial control board. The communication module can be an Ethernet communication module, a wireless communication module, or an IoT communication module. The communication module is connected to the cloud control platform to receive dust removal control parameters issued by the cloud control platform and to upload the operating status of the dust removal system to the cloud control platform.

[0062] The control module is connected to the fan 2 and the negative pressure source respectively, and is used to control the start / stop, speed, or air volume of the fan 2, and to control the start / stop, suction intensity, or suction frequency of the negative pressure source. A dust detection element is located near the receiving chamber 12 or the observation window 7 to detect the dust concentration or the dust state near the observation window 7. A differential pressure detection element is located between the suction chamber 6 and the receiving chamber 12, or between the suction chamber 6 and the external environment, to detect changes in the differential pressure inside and outside the suction chamber 6.

[0063] When the dust detection device detects an increase in dust concentration in the receiving chamber 12 or an increase in the risk of dust adhesion near the observation window 7, the control module increases the speed of the fan 2 and simultaneously increases the suction intensity of the negative pressure source, so that the upper dust blowing structure 14 blows away the dust on the surface of the observation window 7, while the lower dust suction structure 15 promptly sucks out the dust.

[0064] When the differential pressure sensor detects an abnormally large increase in the pressure difference between the inside and outside of the dust collection chamber 6, the control module determines that the first dust filter plate 17 or the second dust filter plate 16 may be at risk of blockage, and uploads maintenance prompt information to the cloud control platform through the communication module. The cloud control platform can issue commands to the control module to reduce load operation, strengthen repeated purging, or stop maintenance to avoid a decrease in dust collection efficiency affecting the continuous operation of the color sorter 1.

[0065] The cloud control platform allows for the preset dust removal operating parameters for different materials. For example, for materials with high dust content or strong adhesion, the cloud control platform issues higher purging and negative pressure suction intensities; for materials with low dust content, the cloud control platform issues lower purging and negative pressure suction intensities to reduce energy consumption and minimize disturbance to the material's falling path.

[0066] The color sorter dust removal system of the present invention achieves efficient cleaning of dust in the observation window 7 and the receiving chamber 12 through the synergistic effect of the upper dust blowing structure 14 and the lower dust suction structure 15.

[0067] During operation, the blower 2 in the upper dust blowing structure 14 generates airflow, which is transported to the blower distributor 9 through the blower pipe 8. After being divided by the distributor plate 94 in the distributor housing 92, the airflow is evenly sprayed out from the flat slit-shaped air outlet 93, forming a sheet-like airflow covering the surface of the observation window 7. This continuously blows away the dust adhering to the surface of the observation window 7, causing the dust to detach from the observation window 7 and enter the receiving chamber 12.

[0068] Simultaneously, the lower suction structure 15, through the suction chamber 6 connected to the negative pressure source, creates a negative pressure environment inside, causing dust and some fine particulate matter in the receiving chamber 12 to be sucked into the suction chamber 6 through the first suction hole 10 and the second suction hole 11. The first dust filter plate 17 and the second dust filter plate 16 filter the incoming airflow and particulate matter, preventing larger particles from entering the suction chamber 6. For the sucked-in material 18 that enters the suction chamber 6 with the airflow but is not carried away, it falls back onto the inclined second dust filter plate 16 under its own weight after the airflow weakens, and then falls back into the receiving chamber 12 along its guide, achieving material recovery.

[0069] Through the above process, the upper dust blowing structure 14 blows away the dust on the surface of the observation window 7, and the lower dust suction structure 15 promptly sucks out the dust that enters the receiving chamber 12 and discharges it to the outside of the equipment. The two form a synergistic dust removal mechanism, which effectively reduces the adhesion of dust on the surface of the observation window 7, improves the sorting accuracy and operational stability of the color sorter 1, and also takes into account the recycling of fine particulate materials.

[0070] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
