Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0024] In the description of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed, they are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0025] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0026] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0027] Please refer to Figure 1The present invention provides a conveyor belt washing device 100, which includes a sedimentation tank 110, a water pump assembly 120, a first spray washing assembly 130, a second spray washing assembly 140, and a return water pipe 150. The water pump assembly 120 is disposed in the sedimentation tank 110 and is used to extract the supernatant after sedimentation. The first spray washing assembly 130 is connected to the water pump assembly 120 and is used to spray wash the conveyor belt. The second spray washing assembly 140 is connected to the water pump assembly 120 and is used to spray wash the corridor. One end of the return water pipe 150 extends into the sedimentation tank 110, and the other end is disposed downstream of the corridor along the extension direction of the corridor.

[0028] Understandably, the mixed liquor entering the sedimentation tank 110 undergoes natural settling under gravity; denser solid particles gradually settle to the bottom of the tank, forming a sludge layer; while the clear water with lower suspended solids content remains stable in the upper layer. The suction port of the water pump assembly 120 (preferably submersible) is located below the liquid surface but above the sludge interface, thereby ensuring continuous and stable extraction of the high-purity upper clear liquid, achieving the effects of recycling, water saving, and energy saving.

[0029] Specifically, the workflow of this embodiment is as follows: the water pump assembly 120 draws the supernatant after sedimentation from the sedimentation tank 110 and supplies it to the first spray washing assembly 130 and the second spray washing assembly 140 respectively. The first spray washing assembly 130 is arranged downstream of the scraper 220 of the conveyor belt 210 and is used to wash the residual material that was not completely removed by the scraper 220 and is still attached to the surface of the conveyor belt; the scraped or washed-off material falls into the lower corridor with the water flow; then, the second spray washing assembly 140 is arranged along the extension direction of the corridor and powerfully washes the material accumulated on the bottom plate and side walls of the corridor, pushing it directionally to the downstream end of the corridor; finally, the washing water carrying solid impurities is guided through the return water pipe 150 and flows back into the sedimentation tank 110, completing the closed path of water circulation.

[0030] It is worth emphasizing that in this embodiment, the water output per unit time of the first spray washing component 130 is less than that of the second spray washing component 140. Since the residue on the conveyor belt surface mainly consists of small particles sporadically adhering to the surface after the scraper 220's operation, the cleaning objective is precise, gentle, and low-impact surface cleaning. Excessive spraying is not only ineffective but may also exacerbate belt wear or cause misalignment. Furthermore, the accumulated materials in the corridor are characterized by large quantities and uneven particle sizes, requiring a larger flow rate to provide sufficient hydraulic flushing energy to ensure the long-term smooth operation of the corridor. Therefore, this embodiment can improve flushing efficiency and achieve water and energy conservation.

[0031] Further, please refer to Figures 1-4The sedimentation tank 110 includes a first sedimentation zone 111, a second sedimentation zone 112, and a third sedimentation zone 113 connected in sequence. The inlet of the return water pipe 150 extends into the first sedimentation zone 111, while the suction port of the water pump assembly 120 is submerged below the liquid surface and above the sediment interface in the third sedimentation zone 113. This embodiment enhances the sedimentation effect step by step by setting multiple sedimentation zones, reducing the content of suspended particles in the upper clear liquid, and ensuring the cleanliness of the water pumped by the water pump assembly 120.

[0032] Specifically, the bottom of the first sedimentation zone 111 is provided with a slope 114 that slopes towards the second sedimentation zone 112; the return water pipe 150 is located upstream of the slope 114; the first sedimentation zone 111 and the second sedimentation zone 112 are connected by a first overflow pipe 115, the inlet end of the first overflow pipe 115 is located downstream of the slope 114; the second sedimentation zone 112 and the third sedimentation zone 113 are connected by a second overflow pipe 116, the inlet end of the second overflow pipe 116 is lower than the outlet end of the first overflow pipe 115.

[0033] It should be noted that the horizontal projected area of ​​the first sedimentation zone 111 is larger than that of the second sedimentation zone 112, and the horizontal projected area of ​​the second sedimentation zone 112 is larger than that of the third sedimentation zone 113, forming a gradient volume distribution from large to small, thereby controlling the hydraulic residence time of each zone to optimize the sedimentation path.

[0034] In this embodiment, the slope of ramp 114 ranges from 12° to 14°. A horizontal sedimentation section extends from the downstream end of ramp 114 to concentrate and deposit slid-down solid impurities. The sidewalls of this sedimentation section are equipped with steel plates or rails to prevent loader operations from directly impacting the pool wall and to facilitate subsequent mechanized dredging operations.

[0035] Understandably, the first sedimentation zone 111 and the second sedimentation zone 112 are connected by a first overflow pipe 115. The inlet of the first overflow pipe 115 is higher than the sedimentation section to prevent large particles from entering, allowing the preliminarily clarified upper layer liquid to overflow into the second sedimentation zone 112. The second sedimentation zone 112 and the third sedimentation zone 113 are connected by a second overflow pipe 116. The inlet of the second overflow pipe 116 is lower than the outlet of the first overflow pipe 115 to match the drop in liquid level in the second sedimentation zone 112 caused by sedimentation, ensuring that the water flow can stably flow to the third sedimentation zone 113. Furthermore, the inlet of the second overflow pipe 116 is located near the liquid surface of the second sedimentation zone 112 to prevent sediment from entering the third sedimentation zone 113.

[0036] It should be emphasized that the integrated regulating sedimentation tank 110 used in this embodiment is designed according to process requirements, with a hydraulic retention time of 45~60min, a surface load controlled within the range of 2~3m³ / (m²·h), a length-to-width ratio of ≥4:1, and a length-to-effective water depth ratio of ≥8:1.

[0037] In addition, a guardrail is installed around the top of the sedimentation tank 110 to prevent workers from accidentally falling.

[0038] Further, please refer to Figures 1-5 In this embodiment, the first spray washing assembly 130 includes a straight pipe 131 and a sealing member 132. One end of the straight pipe 131 is connected to the sealing member 132, and the other end is connected to the water pump assembly 120. The straight pipe 131 is provided with a plurality of through holes 133, which are spaced apart along the axial direction of the straight pipe 131.

[0039] Understandably, the straight pipe 131 is horizontally positioned across the conveyor belt, meaning the axial direction of the straight pipe 131 is perpendicular to the forward direction of the conveyor belt machine 210. Multiple through holes 133 are equidistantly distributed along the axial direction of the straight pipe 131, allowing the water jets from these holes to form a continuous, blind-spot-free coverage zone across the conveyor belt's cross-section, thus effectively and efficiently flushing away impurities that the scraper 220 fails to remove. The design of the through holes 133 effectively limits the water flow and jet impact intensity while ensuring cleaning effectiveness, avoiding the risk of conveyor belt surface wear due to excessive water pressure.

[0040] Specifically, the straight pipe 131 is a DN100 seamless steel pipe, one end of which is sealed using a sealing component 132, and the other end is connected to the water pump assembly 120 via a pipe. In other embodiments, both ends of the straight pipe 131 may also be connected to the water pump assembly 120 via pipes.

[0041] The through-holes 133 have a circular cross-section with a uniform diameter of 8 mm, and are arranged at equal intervals of 18 mm along the axial direction of the straight pipe 131. The spray direction of all through-holes 133 forms a 45° angle with the forward direction of the conveyor belt 210, thereby improving cleaning efficiency and guiding the muddy wastewater after rinsing to the corridor. Under the operating conditions of the device, the water supply pressure at the inlet of the straight pipe 131 should be maintained at 0.3 MPa, corresponding to a flow rate of 0.25~0.3 L / (min·m), that is, the flow rate of the straight pipe 131 is determined according to the width of the conveyor belt.

[0042] In this embodiment, please refer to Figures 1-6 The second spray washing assembly 140 includes a liquid collection pipe 141 and a plurality of nozzles 142. The plurality of nozzles 142 are arranged at intervals along the extension direction of the liquid collection pipe 141 and are all connected to the liquid collection pipe 141. The liquid collection pipe 141 is connected to the water pump assembly 120.

[0043] Understandably, the collection pipe 141 is horizontally installed across the corridor, meaning its axis is perpendicular to the corridor's extension direction. Multiple nozzles 142 are equidistantly arranged along the axis of the collection pipe 141, allowing the water jets from the nozzles to form a continuous, blind-spot-free coverage zone across the corridor's cross-section, thus effectively and efficiently flushing away accumulated impurities. The nozzles 142 have a high flow rate and jet impact intensity, ensuring thorough cleaning of impurities in the corridor, guaranteeing they are flushed downstream and flow into the sedimentation tank 110 via the return water pipe 150.

[0044] Specifically, the liquid collection pipe 141 is made of DN150 seamless steel pipe, with one end sealed by a blind flange and the other end connected to the water pump assembly 120 via a pipe. In other embodiments, both ends of the liquid collection pipe 141 may also be connected to the water pump assembly 120 via pipes.

[0045] The distance between any two adjacent nozzles 142 is 400mm. The nozzles 142 can be made by flattening the ends of DN50 welded steel pipes to form a fan-shaped diffusion jet, effectively expanding the effective width of a single nozzle 142. The spray direction of all nozzles 142 forms a 15° angle with the extension direction of the corridor, thereby improving cleaning efficiency while guiding the flushed muddy wastewater downstream of the corridor. Under operating conditions, the water supply pressure at the inlet of the straight pipe 141 should be maintained at 0.2MPa, corresponding to a flow rate of 0.3~0.4L / (min·m), i.e., the flow rate of the straight pipe 141 is determined according to the width of the conveyor belt.

[0046] Furthermore, in this embodiment, the water pump assembly 120 includes a first water pump 121, a second water pump 122, a first filter 123, and a second filter 124; the first water pump 121, the first filter 123, and the straight pipe 131 are connected in sequence through a pipe; similarly, the second water pump 122, the second filter 124, and the liquid collection pipe 141 are connected in sequence through a pipe.

[0047] Since the water pressure required for through-hole 133 and nozzle 142 differs, this embodiment provides two water pumps to supply the necessary clean water for rinsing the collection pipe 141 and straight pipe 131, respectively. Furthermore, because the liquid pumped from the third sedimentation zone 113 still contains a small amount of small particulate impurities, it must be filtered after pumping to prevent particles from clogging through-hole 133 and nozzle 142, thus ensuring the normal operation of the device.

[0048] To prevent the flushing water from flowing out from other parts of the corridor, thus preventing the nitric acid-containing wastewater from being recycled to the sedimentation tank 110, this embodiment also provides a baffle on the corridor to prevent the water from flowing in other directions and to guide the water to the downstream of the corridor and into the return water pipe 150.

[0049] Specifically, the conveyor belt washing device 100 includes a first baffle 160 and two second baffles 170. The first baffle 160 is located downstream of the corridor along its extension direction. The inlet end of the return water pipe 150 is located on the side of the first baffle 160 near the upstream side of the corridor and is connected to a pre-set return water trough on the corridor. The two second baffles 170 are respectively located on both sides of the corridor, with one end connected to the first baffle 160 and the other end extending towards and adjacent to the water pump assembly 120. That is, the extension direction of the second baffle 170 is parallel to the extension direction of the corridor.

[0050] It should be noted that the return water pipe 150 is made of DN300 welded steel pipe, and both the first baffle 160 and the second baffle 170 can be made of steel plate with a height of 200mm. The distance between the two second baffles 170 is flush with the support of the conveyor belt 210 to avoid affecting the maintenance of the conveyor belt 210 by the staff. The first baffle 160 is not only set downstream of the corridor, but also in the area where there is no water flow down from the conveyor belt 210, thereby avoiding the mixing and disturbance of the dripping water from the conveyor belt with the spray washing water, ensuring that the water flow entering the return water tank mainly comes from the flushing of the second spray washing component 140, thereby improving the stability of the return water quality and the operating efficiency of the sedimentation tank 110.

[0051] This invention also provides a method for washing adhesive tape, using the aforementioned adhesive tape washing device. The specific steps of this method are as follows: S1: Start the tape machine 210.

[0052] S2: Start synchronous mode or intermittent mode.

[0053] S31: In synchronous mode, the water pump assembly 120, the first spray washing assembly 130 and the second spray washing assembly 140 are started synchronously.

[0054] S32: In intermittent mode, while starting the first water pump 121 and the first spray washing assembly 130, the second water pump 122 and the second spray washing assembly 140 are periodically started and stopped.

[0055] Understandably, this embodiment also includes a PLC controller to send instructions to the corresponding equipment (water pump assembly 120, first spray washing assembly 130 and second spray washing assembly 140) via PLC control, thereby controlling the start and stop of the equipment.

[0056] Specifically, the first water pump 121 and the first filter 123 can be started simultaneously when the start command of the conveyor belt 210 is issued; or the first water pump 121 and the first filter 123 can be started after a preset time t1 (e.g., 30–120 seconds) after the conveyor belt 210 is started.

[0057] It should be noted that the delay t1 is set based on the following: allowing the tape to complete at least one full operating cycle. After the scraper 220 has finished its operation, residual impurities are still attached to the tape surface. Starting the rinsing at this time can avoid wasting water resources by spraying too early, and can also prevent the impurities from drying and increasing the cleaning difficulty if the rinsing is too late.

[0058] Since the first spray washing component 130 in this embodiment adopts a valveless straight pipe 131 structure (i.e., constant flow spray washing is achieved through axially distributed multiple holes in the straight pipe 131), its start and stop depend entirely on the start and stop of the upstream first water pump 121. Therefore, the PLC controller does not need to control the first spray washing component 130. However, if the first spray washing component 130 adopts a non-straight pipe 131 structure (e.g., equipped with solenoid valves or other actuators that require active control), the PLC controller needs to synchronously coordinate the start and stop actions of the first water pump 121, the first filter 123, and the first spray washing component 130 so that the components can respond in a timely manner.

[0059] The start and stop of the second nozzle 142 assembly, the second water pump 122, and the second filter 124 are dynamically adapted according to the material accumulation rate in the corridor, specifically supporting two operating modes.

[0060] When there are too many impurities on the tape, causing impurities to accumulate rapidly in the corridor, the synchronous mode is selected. That is, while starting the first water pump 121, the PLC controller simultaneously issues a command to start the second water pump 122, the second filter 124 and all nozzles 142.

[0061] When the accumulation rate of impurities in the corridor is relatively slow, an intermittent mode is selected. That is, while the first water pump 121 runs continuously, the PLC controller controls the start and stop of the second water pump 122 and the nozzle 142 according to a preset cycle; for example, rinsing once every 2 hours, with each rinse lasting 15 minutes. In this way, water consumption can be reduced while ensuring the cleanliness of the corridor, achieving the effect of water and energy conservation.

[0062] This embodiment can also include a vision inspection unit. An industrial camera with an image recognition module is installed above the corridor to periodically collect images of the corridor. The image recognition module then assesses the material coverage area and accumulation thickness. When the recognition result exceeds a preset cleaning threshold, the PLC controller automatically triggers the second water pump 122 and nozzle 142 to flush the corridor. This vision feedback mechanism supports both automatic control and remote manual operation.

[0063] It should be noted that since the first water pump 121 and the first filter 123 start synchronously with the conveyor belt 210, they can also be controlled by hard-wired relays without the need for a PLC; and the timing control of the second water pump 122, the second filter 124 and the nozzle 142 can also be controlled by a time relay or a microcontroller, which can also achieve intermittent operation.

[0064] Furthermore, since evaporation, leakage, and sewage discharge reduce the water volume in the circulating water system, affecting the water balance, an online liquid level sensor can be installed in the suction well. When the water level is lower than the replenishment water level, the electric valve of the replenishment water pipeline will be opened to replenish the system water. When the water level in the cold water tank rises to the stop replenishment water level, the electric valve of the replenishment water pipeline will be closed to stop the system water replenishment.

[0065] Finally, to prevent a decrease in the water volume within the circulating water system due to evaporation, leakage, or sewage discharge, thus affecting the water balance, this embodiment installs an online liquid level sensor in the sedimentation tank 110, specifically in the third sedimentation zone 113. When the detected liquid level is lower than the preset water replenishment start level, the PLC controller automatically opens the electric valve of the water replenishment pipeline to replenish water; when the liquid level rises back to the water replenishment stop level, the electric valve automatically closes, thereby ensuring the normal operation of the device.

[0066] In summary, this embodiment constructs a water circulation flushing system by setting up a sedimentation tank 110, a water pump assembly 120, a first spray washing assembly 130, a second spray washing assembly 140, and a return water pipe 150. The muddy wastewater settles in the sedimentation tank 110, separating the supernatant. The water pump assembly 120 extracts the supernatant and transports it to the first and second spray washing assemblies 130 and 140, respectively, to flush the conveyor belt and the corridor, ensuring their cleanliness. The return water pipe 150 collects the flushing liquid carrying impurities and returns it to the sedimentation tank 110, thus forming a "sedimentation-flushing-recycling" cycle. This embodiment can ensure the cleanliness of the conveyor belt and corridor while reducing the amount of fresh water replenishment and wastewater discharge, thereby achieving water and energy conservation, reducing costs, and avoiding resource waste.

[0067] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
