Description

Technical Field

[0001] This invention belongs to the field of band saw blade steel strip processing equipment, and is applicable to steel strip and saw blade products. Specifically, it relates to the cleaning of oil stains on steel strip and saw blade products before continuous laser welding. Background Technology

[0002] In the existing technology, the cleaning of steel strips (saw blades) and laser welding are carried out on the same production line. Both are continuous cleaning and welding processes with a line speed of 12-20 meters per minute.

[0003] Before being processed into saw blades, steel strips require rust prevention treatment for storage and turnover. Currently, most rust prevention measures on the market involve applying rust-preventive oil to the surface of the steel strip. Due to differences in storage time and production methods, the rust-preventive oil adhering to the steel strip can form an oil film and grease. Increased adhesion of grease and oil film, if not thoroughly cleaned and dried, will cause the following problems during the subsequent laser welding process: 1. It will generate significant amounts of oil fumes and spatter, contaminating the laser welding head; 2. Impurities will form during the welding process, affecting the quality of the weld strength; 3. Porosity and other defects will occur during laser welding, leading to incomplete welds and affecting the quality of the weld strength. Furthermore, the annealing process will also generate increased oil fumes and impurities, directly affecting the quality and stability of the annealed steel strip.

[0004] The current cleaning method involves symmetrical brushing, followed by adding cleaning agent and rinsing the steel strip with a regular water pump. After rinsing, the steel strip is rinsed with a regular water pump, and then dried with compressed air.

[0005] However, when there is a thick oil film and grease on the steel strip, the above cleaning method is not effective and the oil stains are not cleaned properly. Summary of the Invention

[0006] The problem this invention aims to solve is that when there is a thick oil film and grease on the steel strip, the existing cleaning methods fail to clean the oil stains thoroughly. The invention provides a cleaning device and method for strip metal components.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a cleaning device for strip metal components, including a brush device for cleaning the surface of the strip metal components and a drying device for drying the surface of the strip metal components, wherein the brush device and the drying device are arranged sequentially in the running direction of the strip metal components and are both mounted on a base.

[0008] The cleaning device also includes a scraping device for scraping the surface of the strip metal element; the brush device is provided with a scraping device on the upstream side of the running direction of the strip metal element.

[0009] The scraping device includes a first soft scraping component, a second soft scraping component, a first abutting component for abutting the first soft scraping component in a first direction, and a second abutting component for abutting the second soft scraping component in a second direction; the first direction and the second direction are opposite directions;

[0010] The first soft scraper and the second soft scraper form a running channel for the strip metal element; the first soft scraper and the second soft scraper are respectively used to contact the upper surface and the lower surface of the strip metal element located in the running channel.

[0011] With the above setup, before cleaning with the brush device, the first and second soft scraping parts of the scraping device are used to clean the upper and lower surfaces of the strip metal element (hereinafter referred to as "the element"), and the first and second abutting parts are used to abut against each other, so that the first and second soft scraping parts have a good contact effect with the surface of the strip metal element, thereby facilitating the removal of grease from the surface by scraping with the first and second soft scraping parts.

[0012] In the above technical solution, the scraping device further includes a spring sleeved on the outside of the first abutting member and a scraping device housing fixedly connected to the base;

[0013] The scraping device housing is fixedly equipped with a first guide limiting member, a second guide limiting member, and a support base; the support base forms the second abutment member;

[0014] The first guide limiting member, the second guide limiting member, the first soft scraping member, the second soft scraping member, and the support base are arranged sequentially along the first direction; the first direction is perpendicular to the running direction of the strip metal element.

[0015] The first abutting member passes through the first guide limiting member and the second guide limiting member in sequence, and the first abutting member extends from the side of the first guide limiting member away from the second guide limiting member, and the first abutting member extends from the side of the second guide limiting member away from the first guide limiting member and then abuts against the first soft scraping member.

[0016] The outer wall of the first abutting member is provided with a protrusion that extends outward toward the spring;

[0017] The spring is sleeved on the outside of the first abutting member and is positioned between the first guide limiting member and the second guide limiting member; the two ends of the spring are respectively used to abut the first guide limiting member and the protrusion.

[0018] With the above configuration, the abutment and support base abut against the first and second soft scraping components respectively, ensuring good contact between the first and second soft scraping components and the component. This allows for scraping of the component surface during operation, achieving a better degreasing effect. In this scheme, the spring is always in a contracted state. The two ends of the contracted spring press against the first guide limiter and the protrusion (i.e., the spring is limited by the first guide limiter and the protrusion on both sides). Under the pressure of the spring on the protrusion, the abutment will move towards the second guide limiter (it tends to move). If the lower end of the abutment does not stop moving due to the component's height, the abutment will continue to move until the protrusion contacts the second guide limiter, resulting in a better abutment effect. When the component has a large thickness, the component will exert a force on the abutment in a second direction (approaching the first guide limiter), causing the spring to be compressed. Therefore, the scraping device of the present invention not only allows the first soft scraping component and the second soft scraping component to have good contact with the component, but also can adapt to components of different heights. Under the action of the spring in the compressed state, the first soft scraping component and the second soft scraping component still have good contact with the component for components of different heights, so as to achieve the scraping effect.

[0019] In the above technical solution, the scraping device further includes a first rigid mounting component and a second rigid mounting component;

[0020] The first rigid mounting component is disposed between the second guide limiting component and the first soft scraping component;

[0021] The second rigid mounting component is disposed between the second soft scraping component and the support base;

[0022] The first rigid mounting component, the second rigid mounting component, the first soft scraping component, and the second soft scraping component constitute a scraping structure;

[0023] The scraping device housing is also connected to a mounting limiter for limiting the scraping structure on both sides in the running direction of the strip metal element.

[0024] With the above configuration, the first abutting member applies abutting force to the first soft scraping member through the first rigid mounting member. When the first abutting member applies force, the support seat also applies abutting force to the second soft scraping member through the second rigid mounting member, thereby avoiding the problem that applying abutting force directly to the soft scraping member may cause damage to the soft scraping member.

[0025] In a preferred embodiment, the first rigid mounting member is an L-shaped structure with its opening facing downwards, and the second rigid mounting member is an L-shaped structure with its opening facing upwards; the opening shape of the first rigid mounting member is adapted to the shape of the first soft scraping member; and the opening shape of the second rigid mounting member is adapted to the shape of the second soft scraping member.

[0026] With the above settings, the L-shaped rigid mounting component can limit the corresponding soft scraping component, minimizing the displacement of the soft scraping component during component operation.

[0027] In the above technical solution, a baffle fixed to the housing of the scraping device is provided above the limiting member located on one side of the scraping structure, and the surface of the baffle is perpendicular to the running direction of the strip metal element.

[0028] A limiting rod is provided above the limiting member on the other side of the scraping structure, and an installation groove for accommodating the limiting rod is also provided on the scraping device housing; the limiting rod extends perpendicularly to the height direction of the scraping device housing and perpendicularly to the running direction of the strip metal element.

[0029] During the applicant's research, it was discovered that when the component has a certain height, the height of the first rigid mounting component may exceed the height of the limiting component, making it impossible for the limiting component to perform its limiting function. Through the above-mentioned design, when the component has a certain height, resulting in a relatively high height for the first rigid mounting component, the baffle and limiting bar are used to limit the first rigid mounting component on both sides in the component's running direction, preventing the first rigid mounting component from dislodging under the frictional force of the strip metal component.

[0030] In the above technical solution, a limiting protrusion is provided on the wall surface of the scraping device housing facing the spring, and the limiting protrusion extends toward the spring and is spaced apart from the spring;

[0031] The first abutment is rotatable, and the outer wall of the first abutment is provided with an extension that extends outward toward the spring.

[0032] The limiting protrusion is disposed between the first guide limiting member and the second guide limiting member;

[0033] The spring has a first limiting state and a second limiting state;

[0034] When the spring is in the first limiting state, the protruding part abuts against the second guide limiting member.

[0035] When the spring is in the second limiting state, the protrusion abuts against the limiting protrusion, and the protrusion has a gap with the second guide limiting member.

[0036] With the above settings, when it is necessary to replace the hard mounting part or the soft scraping part, the limiting protrusion on the outer wall of the first abutment part can be limited by the limiting protrusion on the wall of the scraping device housing, so that the first abutment part retracts and does not apply abutting force to the hard mounting part, thereby facilitating replacement.

[0037] In the above technical solution, the base is fixed with a first cleaning chamber;

[0038] A box extending outward from the scraping device housing is fixedly installed on the side wall of the scraping device housing, and the side of the box away from the scraping device housing is fixedly installed on the inner wall of the first cleaning chamber; the box is a hollow structure.

[0039] During the applicant's research, it was discovered that because the scraping device needs to scrape the components, the scraping device housing is fixed inside the first cleaning chamber. Since the scraping device housing is generally positioned close to the inner wall of the first cleaning chamber, the distance between the positions where the first and second abutting members abut against the soft scraping component (i.e., the position of the soft scraping component) and the inner wall of the first cleaning chamber is relatively short. This makes manual replacement of the soft scraping component or operation on the abutting position very inconvenient. The proposed solution, by incorporating a housing and fixing the scraping device housing to the inner wall of the first cleaning chamber through the housing, increases the space available for these operations within the housing's cavity, thus facilitating operation.

[0040] In the above technical solution, the brush device includes a rotating shaft, a brush mounted on the rotating shaft, and a rotating shaft drive motor for driving the rotating shaft to rotate;

[0041] The shaft has a shaft body.

[0042] In a preferred embodiment, a first annular groove is provided on the rotating shaft body, and a first sealing ring is fitted on the portion of the rotating shaft body without the annular groove; the brush, the first annular groove, the first sealing ring, and the rotating shaft drive motor are arranged sequentially along the length of the rotating shaft body; the radial dimension of the portion of the rotating shaft body with the annular groove is smaller than the radial dimension of the portion of the rotating shaft body without the annular groove.

[0043] During the applicant's research, it was discovered that because the brush needs continuous cleaning (e.g., spraying water) during operation to prevent impurities from accumulating on the component surface, water may reach the rotating shaft and travel through it to the drive motor of the brush assembly. Prolonged use could easily damage the device. The above design, by creating a first annular groove, prevents water flowing along the rotating shaft surface from entering the groove and thus preventing it from continuing towards the drive motor. A first sealing ring is fitted onto the rotating shaft after the first annular groove, creating a diameter difference between the rotating shaft at the first annular groove position (smaller than the shaft diameter), the rotating shaft body position (equal to the shaft diameter), and the position where the first sealing ring is fitted (larger than the shaft diameter). This progressively increasing diameter makes it difficult for water that might flow back from the first annular groove to the rotating shaft to pass through the first sealing ring, thus achieving a better water-proofing effect and protecting the device.

[0044] In a more preferred embodiment, the base is fixed with a first cleaning chamber; a rotating shaft housing is also installed on the rotating shaft with a gap between it and the rotating shaft; the rotating shaft housing is fixedly connected to the outer wall of the first cleaning chamber, and the rotating shaft passes through the wall of the first cleaning chamber and extends into the first cleaning chamber.

[0045] The rotating shaft housing has a first wall surface facing the wall surface of the first cleaning chamber; the first sealing ring is located in the inner cavity of the rotating shaft housing, and the first annular groove is located on the outer side of the rotating shaft housing.

[0046] With the above configuration, the outer side of the shaft housing also serves to separate the first annular groove located on the shaft housing and the first sealing ring located on the inner side of the shaft housing. That is, the shaft housing and the first sealing ring together block the water flowing along the shaft.

[0047] In a more preferred embodiment, a second annular groove is further provided on the rotating shaft body; a second sealing ring is also fitted on the portion of the rotating shaft body where the annular groove is not provided.

[0048] Along the length of the main shaft body, the brush, the first annular groove, the first sealing ring, the second annular groove, and the second sealing ring are arranged sequentially.

[0049] With the above configuration, by creating the second annular groove, water flowing along the surface of the shaft will enter the second annular groove, thus preventing it from continuing to move towards the drive motor. This configuration creates a diameter difference between the shaft at the second annular groove position (smaller than the shaft diameter), the shaft body position (equal to the shaft diameter), and the position where the second sealing ring is fitted (larger than the shaft diameter), meaning the diameters increase sequentially. This makes it difficult for water that might not be blocked by the first sealing ring to enter the second annular groove and then flow out onto the shaft body to pass through the second sealing ring position, thus achieving a better water-proofing effect and protecting the device.

[0050] In the above technical solution, the brush device has a brush for brushing the upper surface of the strip metal element and a brush for brushing the lower surface of the strip metal element; in the running direction of the strip metal element, the brush for brushing the upper surface of the strip metal element and the brush for brushing the lower surface of the strip metal element are staggered.

[0051] During its research, the applicant discovered that existing symmetrical brush cleaning mechanisms (which clean the upper and lower surfaces of components separately) are prone to gearbox jamming, motor burnout, and brush durability issues. The above-described design, which staggers the brushes used to clean the upper and lower surfaces of the strip-shaped metal component, avoids these problems.

[0052] In the above technical solution, the base is fixed with a first cleaning chamber with a lower opening and a first liquid storage chamber with a higher opening, and the first cleaning chamber and the first liquid storage chamber are respectively arranged in the height direction of the cleaning device;

[0053] The brushes of both the scraping device and the brush device are disposed in the first cleaning chamber; the cleaning device also includes a first rinsing mechanism for rinsing the surface of the strip metal element in the first cleaning chamber.

[0054] The first liquid storage cavity is provided with a first oil-water separation device, which has an oil outlet pipe connecting the inner cavity of the first liquid storage cavity to the outside and a water outlet connecting the inner cavity of the first liquid storage cavity to the outside; the water outlet is connected to the water inlet of the first flushing mechanism.

[0055] The above configuration ensures that the upper first cleaning chamber and the lower first liquid storage chamber are correspondingly positioned, allowing the treated water to circulate between the first cleaning chamber and the first liquid storage chamber, minimizing contamination of the treated water in the next processing unit. The inclusion of a first oil-water separator achieves oil-water separation, reducing the risk of oil accumulation in the water tank leading to repeated contamination during circulation, and allowing the recovered water to be reused in the first cleaning chamber.

[0056] In the above technical solution, the cleaning device also forms an operating channel for strip-shaped metal elements;

[0057] The brush device is also provided with a scraping device on the downstream side of the running direction of the strip metal element.

[0058] The scraping device located downstream of the brush device is positioned near the first channel outlet, which is the outlet of the portion of the operating channel located in the first cleaning chamber.

[0059] With the above configuration, a scraping device is installed in the first cleaning chamber near the outlet of the first channel, so as to retain the water on the surface of the component in this chamber as much as possible, avoid carrying water containing impurities into the next chamber as much as possible, and minimize the pollution of the treatment water in the next chamber.

[0060] In a preferred embodiment, a first blowing chamber is provided on the downstream side of the first cleaning chamber, and a first fan is provided in the first blowing chamber for blowing off the liquid on the surface of the strip metal element; the inner cavity of the first blowing chamber is connected to the liquid inlet of the first rinsing mechanism.

[0061] With the above configuration, the first fan can blow the liquid on the surface of the component after it has been treated in the first cleaning chamber into the first blowing chamber, and the liquid can be recycled into the first rinsing mechanism, thereby avoiding the impact on the next stage of processing and reducing the pollution to the next stage of processing.

[0062] In the above technical solution, the first oil-water separation device includes an oil suction device;

[0063] The oil suction device has an oil suction box and at least two floating components arranged around the oil suction box, and each floating component is fixedly connected to the oil suction box.

[0064] The oil suction box is fixedly connected to the oil outlet pipe, and the inner cavity of the oil suction box is connected to the inner cavity of the oil outlet pipe; an oil inlet is provided on the side wall of the oil suction box.

[0065] With the above setup, the oil on the upper surface is guided into the oil suction box through the oil inlet, and then delivered to the outside of the first liquid storage chamber through the oil outlet pipe. By installing floating components around the oil suction box, the oil suction box can maintain good balance on the liquid surface.

[0066] In a preferred embodiment, the floater is a hollow structure. Floats with a hollow structure exhibit better buoyancy on oil surfaces.

[0067] In a preferred embodiment, the oil inlet includes an oil inlet groove and / or an oil inlet hole formed on the side wall of the oil suction box; the oil inlet groove extends downward in the height direction of the oil suction box.

[0068] In a more preferred embodiment, the width of the oil inlet groove gradually increases from bottom to top in the height direction of the oil suction box.

[0069] With the above configuration, the oil inlet grooves are designed to gradually increase in width from bottom to top, with the grooves at higher positions being wider. This ensures that the wider grooves correspond to the grease at higher liquid levels, facilitating the absorption of the grease and guiding it into the oil suction box.

[0070] In the above technical solution, the first liquid storage cavity includes a liquid processing cavity and a liquid receiving cavity with an opening at the top;

[0071] The first cleaning chamber and the liquid receiving chamber are respectively arranged in the height direction of the cleaning device, and the first cleaning chamber and the liquid processing chamber are staggered.

[0072] The liquid processing chamber has a first end wall and a second end wall that are disposed opposite to each other; the first end wall, the second end wall, and the two side walls of the liquid processing chamber form an inner cavity of the liquid processing chamber;

[0073] K partitions are fixed in the liquid processing chamber, where K ≥ 1;

[0074] Each partition is fixedly connected to the two side walls of the liquid processing chamber, thereby dividing the liquid processing chamber into K+1 independent and sequentially connected sub-cavities when viewed from above.

[0075] The side wall and / or the first end wall of the sub-cavity adjacent to the first end wall are provided with an inlet that communicates with the liquid receiving cavity outlet.

[0076] A first oil-water separation device is provided in at least one sub-cavity other than the sub-cavity adjacent to the first end wall.

[0077] The side wall and / or the second end wall of the sub-cavity adjacent to the second end wall are provided with water outlets.

[0078] With the above configuration, the liquid that falls from the first cleaning chamber after processing the components first enters the liquid receiving chamber, and then enters the sub-cavities in the liquid processing chamber through the liquid receiving chamber's outlet and inlet. Although the liquid level in the liquid receiving chamber is unstable (due to the impact of the water flow falling from the first cleaning chamber above), and the liquid level in the sub-cavities adjacent to the first end wall is also not stable, the liquid flow into other sub-cavities (i.e., those other than those adjacent to the first end wall) is less impacted after passing through the channels between the sub-cavities. This results in a more stable liquid level, making it easier for the oil and water to separate due to their different densities, thus facilitating processing by the first oil-water separation device.

[0079] In a preferred embodiment, the partition is spaced apart from the top / bottom surface of the liquid treatment chamber, thereby forming an opening above / below the partition that connects two sub-cavities on both sides of the partition.

[0080] In a preferred embodiment, the height of the partition decreases sequentially from the first end wall to the second end wall.

[0081] In a preferred embodiment, the bottom end of the partition closest to the first end wall extends to the bottom surface of the liquid treatment chamber, and the top end of the partition closest to the first end wall is spaced apart from the top surface of the liquid treatment chamber, thereby forming an opening above the partition that connects two sub-cavities on both sides of the partition; the height of the top end of the partition closest to the first end wall is greater than the height of the top ends of the other partitions.

[0082] The bottom ends of the other partitions extend to the bottom surface of the liquid processing chamber, or the bottom ends of the other partitions are spaced apart from the bottom surface of the liquid processing chamber.

[0083] With the above configuration, when the liquid level in the first sub-cavity (the sub-cavity adjacent to the first end wall) reaches the height of the top of the partition, the liquid flows along the side of the partition into other sub-cavities. This makes the liquid flow rate into other sub-cavities relatively slow, which makes it easier to form an oil-water separation interface, thus facilitating oil-water separation.

[0084] When the bottom of other baffles extends to the top / bottom surface of the liquid treatment chamber (i.e., only forming an opening below / above the baffle), other sub-cavities form openings below / above, making the liquid flow rate relatively slow and easily forming an oil-water separation interface, thus facilitating oil-water separation.

[0085] In the above technical solution, the drying device is a first air outlet device, which includes a first air outlet device housing body forming a closed structure, a first planar air guide plate, a second planar air guide plate, and a sealing side plate.

[0086] The first air outlet device housing body has an axis, and the cross section of the first air outlet device housing body perpendicular to the axis is an arc shape (that is, the inner wall of the first air outlet device housing body is arc-shaped).

[0087] One end of the first planar air guide plate and one end of the second planar air guide plate are respectively connected to the main body of the first air outlet device housing.

[0088] Both the first planar air guide plate and the second planar air guide plate extend outward from the main body of the first air outlet device housing, so that the other ends of the first planar air guide plate and the other ends of the second planar air guide plate are connected to each other, thereby forming a V-shaped structure; the sealing side plates are installed on both sides of the V-shaped structure.

[0089] The intersection of the first planar air guide plate and the second planar air guide plate forms an airflow outlet. The extension directions of the first planar air guide plate and the second planar air guide plate both pass through the surface of the strip metal element located in the running channel.

[0090] With the above configuration, the airflow first passes through the main body of the first air outlet device, which has a ring-shaped wall structure, ensuring smooth airflow. Then, it flows out through the air outlet at the intersection of the first and second planar guide plates, achieving good airflow guidance and resulting in effective airflow to the component surface. The inner wall of the main body of the first air outlet device is arc-shaped. When the airflow reaches the inner wall, it flows smoothly along the arc. When it reaches the positions of the first and second planar guide plates, it is guided by them and exits through the air outlet.

[0091] In a preferred embodiment, the airflow inlet of the first air outlet housing body is located at one end of the first air outlet housing body or near one end of the first air outlet housing body, and the V-shaped structure is located near the other end of the first air outlet housing body.

[0092] With the above configuration, the airflow entering from the airflow inlet can move to the V-shaped structure located near the other end of the housing of the first air outlet, thereby exiting from the airflow outlet.

[0093] In the above technical solution, the base is fixed with a second cleaning chamber located downstream of the first cleaning chamber; the first cleaning chamber and the second cleaning chamber are not in communication with each other;

[0094] The cleaning device also includes a second rinsing mechanism for rinsing the surface of the strip metal element in the second cleaning chamber.

[0095] The inner cavity of the second cleaning chamber is connected to the liquid inlet of the second rinsing mechanism.

[0096] With the above configuration, since the first cleaning chamber and the second cleaning chamber are not connected to each other, the liquid in the first cleaning chamber with chemical residues of cleaning agent can be prevented from entering the second cleaning chamber, thereby reducing the impact on the water quality of the second rinsing mechanism in the second cleaning chamber.

[0097] Preferably, the first cleaning chambers and the second cleaning chambers are not connected to each other.

[0098] With the above setup, different first cleaning chambers are not connected to each other, and different second cleaning chambers are not connected to each other, thus avoiding cross-contamination between different cleaning chambers.

[0099] Preferably, a second blowing chamber is provided on the downstream side of the second cleaning chamber, and a second blower is provided in the second blowing chamber for blowing off the liquid on the surface of the strip metal element; the inner cavity of the second blowing chamber is connected to the liquid outlet of the second rinsing mechanism.

[0100] With the above configuration, the liquid on the surface of the component after being treated by the second cleaning chamber can be blown into the second blowing chamber by the second fan, and the liquid can be recycled into the second rinsing mechanism, thereby avoiding the impact on the next stage of processing and reducing the pollution to the next stage of processing.

[0101] The present invention also provides a cleaning method using the above-described cleaning apparatus, the cleaning method comprising:

[0102] Step A: Use a scraping device to scrape the surface of the strip metal component;

[0103] Step B: Rinse the surface of the strip metal component with a rinsing solution at a preset temperature.

[0104] Step C: Clean the surface of the strip metal component using a brush device, and continuously rinse the brush of the brush device with a rinsing liquid, wherein the rinsing liquid is clean water or a mixture of clean water and cleaning agent;

[0105] Step D: Rinse the surface of the strip-shaped metal component with clean water;

[0106] Step E: Dry the surface of the strip metal component using the first air outlet device.

[0107] In a preferred embodiment, the step between step C and step D further includes:

[0108] Step C1: Use a scraping device to scrape the surface of the strip metal component. By performing step C1 after step C, that is, by scraping to remove surface moisture, the surface liquid is prevented from being carried into the next stage of water treatment, thus reducing the risk of contaminating the water in the next stage of water treatment.

[0109] In a more preferred embodiment, the step between step C1 and step D further includes:

[0110] Step C2: Use the first fan to blow off the liquid from the surface of the strip metal element.

[0111] The advantages and positive effects of this invention include:

[0112] 1. Using soft scrapers to remove grease from the surface of components, and using water with a certain temperature to rinse can soften the oil film on the surface of components, resulting in better removal of grease and graded cleaning.

[0113] 2. Reducing the impact of water seepage between different chambers can reduce the use of cleaning agents and reduce the residue of cleaning agents on the steel belt.

[0114] 3. The floating oil in the first liquid storage chamber can be removed in time, thereby making effective use of the cleaning water and minimizing water waste.

[0115] 4. The staggered arrangement of the brushes reduces the resistance between them, making the corresponding structure of the brush device (such as brushes, gearbox, motor) more durable and the cleaning effect better. Attached Figure Description

[0150] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments, and should not be considered as limiting the scope of implementation of this invention. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0151] like Figure 1 , Figure 2 As shown, the present invention provides a cleaning device for strip metal components, including a brush device 2 for cleaning the upper and lower surfaces of the strip metal component 200 (i.e., the brush device 2 is respectively provided on the upper and lower surfaces), and a first air outlet device 4 for drying the upper and lower surfaces of the strip metal component 200 (i.e., the first air outlet device 4 is respectively provided on the upper and lower surfaces). The brush device 2 and the first air outlet device 4 are arranged sequentially in the running direction of the strip metal component 200 and are both mounted on the base 100A.

[0152] The cleaning device also includes a scraping device 1 for scraping the surface of the strip metal element 200. The brush device 2 is provided with the scraping device 1 on the upstream side of the running direction of the strip metal element 200.

[0153] In this application, structure X is located upstream of structure Y, meaning that in the operating direction, structure X is behind structure Y (i.e., structure X is closer to the inlet of strip metal element 200 than structure Y); structure X is located downstream of structure Y, meaning that in the operating direction, structure A is in front of structure B (i.e., structure X is closer to the outlet of strip metal element 200 than structure Y). "Upstream" and "downstream" do not indicate a height difference between structures X and Y (they can be at the same height or one can be higher than the other), but only indicate their front-to-back relationship in the operating direction.

[0154] The scraping device 1 includes a first soft scraping element 151, a second soft scraping element 152, a first abutting element 11 for abutting the first soft scraping element 151 in a first direction, and a second abutting element for abutting the second soft scraping element 152 in a second direction. The first direction and the second direction are opposite directions. Both the first direction and the second direction are parallel to the height direction.

[0155] The first soft scraper 151 and the second soft scraper 152 form an operating channel 200A for the strip metal element 200. The first soft scraper 151 and the second soft scraper 152 are respectively used to contact the upper surface and lower surface of the strip metal element 200 located in the operating channel 200A.

[0156] like Figure 3-1 , Figure 3-2 , Figure 3-3 , Figure 3-4 , Figure 3-5 , Figure 3-6 The diagram shown is a structural schematic of the scraping device according to an embodiment of the present invention. Wherein, Figure 3-4 The first soft scraper 151 and the second soft scraper 152 are not shown in the diagram. The scraping device 1 also includes a spring 12 and a scraping device housing 1A that is fixedly connected to the base 100A.

[0157] The scraping device housing 1A is fixedly mounted with a first guide limiting member 131, a second guide limiting member 132, and a support base 18. The support base 18 forms the second abutment member. The first guide limiting member 131 and the second guide limiting member 132 can be limiting plates installed on the scraping device housing 1A, and both have through holes for the first abutment member 11 to pass through.

[0158] The first guide limiting member 131, the second guide limiting member 132, the first soft scraping member 151, the second soft scraping member 152, and the support base 18 are arranged sequentially along a first direction. The first direction is perpendicular to the running direction of the strip metal element 200.

[0159] The first abutment 11 passes sequentially through the first guide limiting member 131 and the second guide limiting member 132, and the first abutment 11 extends from the side of the first guide limiting member 131 away from the second guide limiting member 132, and the first abutment 11 extends from the side of the second guide limiting member 132 away from the first guide limiting member 131 to abut against the first soft scraping member 151. The first abutment 11 can move up and down in the height direction.

[0160] The outer wall of the first abutment 11 is provided with an extension 171 that extends outward toward the outside of the spring 12.

[0161] The spring 12 is sleeved on the outside of the first abutment member 11 and is disposed between the first guide limiting member 131 and the second guide limiting member 132. The two ends of the spring 12 abut against the first guide limiting member 131 and the protrusion 171, respectively.

[0162] The scraping device 1 also includes a first rigid mounting component 141 and a second rigid mounting component 142.

[0163] The first rigid mounting component 141 is disposed between the second guide limiting component 132 and the first soft scraping component 151.

[0164] The second rigid mounting component 142 is disposed between the second soft scraping component 152 and the support base 18.

[0165] The first rigid mounting component 141, the second rigid mounting component 142, the first soft scraping component 151, and the second soft scraping component 152 constitute a scraping structure.

[0166] The first rigid mounting component 141 and the second rigid mounting component 142 may be made of nylon sheet. The first soft scraping component 151 and the second soft scraping component 152 may be made of wool felt.

[0167] The scraping device housing 1A is also connected to a mounting limiting member 19 for limiting the two sides of the scraping structure in the running direction of the strip metal element 200.

[0168] Preferably, the first rigid mounting member 141 has a downward-facing L-shaped structure, and the second rigid mounting member 142 has an upward-facing L-shaped structure. The opening shape of the first rigid mounting member 141 is adapted to the shape of the first soft scraping member 151. The opening shape of the second rigid mounting member 142 is adapted to the shape of the second soft scraping member 152.

[0169] A baffle 163 is provided above the limiting member 19 located on one side of the scraping structure and fixed to the scraping device housing 1A. The surface of the baffle 163 is perpendicular to the running direction of the strip metal element 200.

[0170] A limiting rod 161 is provided above the limiting member 19 on the other side of the scraping structure. The scraping device housing 1A is also provided with a mounting groove 162 for accommodating the limiting rod 161. The limiting rod 161 extends perpendicularly to the height direction of the scraping device housing 1A and perpendicularly to the running direction of the strip metal element 200.

[0171] The wall surface of the scraping device housing 1A facing the spring 12 is provided with a limiting protrusion 172, which extends toward the spring 12 and is spaced apart from the spring 12.

[0172] The first abutting member 11 is rotatable, and the limiting protrusion 172 is disposed between the first guide limiting member 131 and the second guide limiting member 132.

[0173] The spring 12 has a first limiting state and a second limiting state.

[0174] like Figure 3-3 , Figure 3-4 As shown, when the spring 12 is in the first limiting state, the protrusion 171 abuts against the second guide limiting member 132.

[0175] like Figure 3-5 As shown, when the spring 12 is in the second limiting state, the protrusion 171 abuts against the limiting protrusion 172, and the protrusion 171 has a gap with the second guide limiting member 132.

[0176] The base 100A is fixed with a first cleaning chamber 101. Scraping devices can be installed at both the inlet and outlet of the first cleaning chamber 101.

[0177] A housing 1B extending outward from the scraping device housing 1A is fixedly installed on the side wall of the scraping device housing 1A. The side of the housing 1B away from the scraping device housing 1A is fixedly installed on the inner wall of the first cleaning chamber 101. The housing 1B has a hollow structure. That is, one side of the housing 1B is fixed to the scraping device housing 1A, and the other side is fixedly installed on the inner wall of the first cleaning chamber 101, so that there is a gap between the scraping device housing 1A and the inner wall of the first cleaning chamber 101.

[0178] In the direction of component operation, one side of the scraping structure is limited by two spaced-apart mounting limiters 19 (e.g., disposed in the housing 1B), and the other side of the scraping structure is limited by two other spaced-apart mounting limiters 19 (e.g., disposed near the limiter bar 161). The mounting limiters 19 are fixed to the scraping device housing 1A and can extend in the height direction of the scraping device.

[0179] like Figure 4-1 , Figure 4-2 , Figure 4-3 , Figure 4-4 , Figure 4-5 The diagram shows a schematic representation of the brush device according to an embodiment of the present invention. The brush device 2 includes a rotating shaft 210, a brush 24 mounted on the rotating shaft 210, and a rotating shaft drive motor 25 for driving the rotating shaft 210 to rotate.

[0180] The rotating shaft 210 has a rotating shaft body 21.

[0181] Preferably, the rotating shaft body 21 has a first annular groove 221, and the portion of the rotating shaft body 21 without the annular groove is fitted with a first sealing ring 231. Along the length of the rotating shaft body 21, the brush 24, the first annular groove 221, the first sealing ring 231, and the rotating shaft drive motor 25 are arranged sequentially. The radial dimension of the portion of the rotating shaft body 21 with the annular groove is smaller than the radial dimension of the portion of the rotating shaft body 21 without the annular groove.

[0182] More preferably, the base 100A is fixed with a first cleaning chamber 101. A rotating shaft housing 2A is also installed on the rotating shaft 210 with a gap between it and the rotating shaft 210. The rotating shaft housing 2A is fixedly connected to the outer wall of the first cleaning chamber 101, and the rotating shaft 210 passes through the wall of the first cleaning chamber 101 and extends into the first cleaning chamber 101.

[0183] The rotating shaft housing 2A has a first wall surface 2A1 facing the wall surface of the first cleaning chamber 101. The first sealing ring 231 is located in the inner cavity of the rotating shaft housing 2A, and the first annular groove 221 is located on the outer side of the rotating shaft housing 2A.

[0184] More preferably, a second annular groove 222 is also provided on the rotating shaft body 21. A second sealing ring 232 is also fitted on the portion of the rotating shaft body 21 where the annular groove is not provided.

[0185] Along the length of the rotating shaft body 21, the brush 24, the first annular groove 221, the first sealing ring 231, the second annular groove 222, and the second sealing ring 232 are arranged in sequence.

[0186] The brush device 2 has a brush 24 for brushing the upper surface of the strip metal element 200 and a brush 24 for brushing the lower surface of the strip metal element 200.

[0187] like Figure 4-4 In a preferred embodiment, the brush 24 for washing the upper surface of the strip metal element 200 and the brush 24 for washing the lower surface of the strip metal element 200 are staggered in the running direction of the strip metal element 200.

[0188] like Figure 1 , Figure 2 , Figure 3-6As shown, the base 100A is fixed with a first cleaning chamber 101 with a lower opening and a first liquid storage chamber 201 with a higher opening. The first cleaning chamber 101 and the first liquid storage chamber 201 are respectively arranged in the height direction of the cleaning device.

[0189] Both the scraping device 1 and the brush device 2 have their brushes 24 disposed within the first cleaning chamber 101. The cleaning device also includes a first rinsing mechanism 301 for rinsing the surface of the strip metal element 200 within the first cleaning chamber 101. The first rinsing mechanism 301 may be disposed within the first cleaning chamber 101.

[0190] The first liquid storage chamber 201 is equipped with a first oil-water separation device, which has an oil outlet pipe 32 connecting the inner cavity of the first liquid storage chamber 201 to the outer side and a water outlet. The water outlet is connected to the water inlet of the first flushing mechanism 301.

[0191] like Figure 1 , Figure 2 , Figure 3-5 As shown, the cleaning device also forms an operating channel 200A for the strip metal element 200.

[0192] like Figure 2 , Figure 3-7 As shown, a scraping device 1 is also provided on the downstream side of the brush device 2 (that is, a scraping device 1 is provided on both the upstream and downstream sides of the brush device 2).

[0193] The scraping device 1, located downstream of the brush device 2, is positioned near the outlet of the first channel. The scraping device 1, located upstream of the brush device 2, is positioned near the inlet of the first channel. The inlet and outlet of the first channel are respectively the inlet and outlet of the portion of the operating channel 200A located in the first cleaning chamber 101.

[0194] like Figure 5-1 , Figure 5-2 , Figure 5-3 The diagram shown is a structural schematic of the oil suction device according to an embodiment of the present invention. The first oil-water separation device includes an oil suction device 3.

[0195] The oil suction device 3 has an oil suction box 31 and at least two floating members 33 arranged around the oil suction box 31. Each floating member 33 is fixedly connected to the oil suction box 31. The density of oil is less than that of water. The density of the floating member 33 is less than that of water and less than or equal to that of oil. That is, the floating member 33 floats on the oil surface P0 (i.e., the upper surface of the liquid in the storage cavity), or is located above the water surface (i.e., the oil-water interface PW) and below the oil surface P0.

[0196] The bottom end of the oil suction box 31 is fixedly connected to the oil outlet pipe 32, and the inner cavity of the oil suction box 31 communicates with the inner cavity of the oil outlet pipe 32. An oil inlet is provided on the side wall of the oil suction box 31.

[0197] Preferably, the floating component 33 has a hollow structure.

[0198] Preferably, the oil inlet includes an oil inlet groove 311 and / or an oil inlet hole 312 formed on the side wall of the oil suction box 31.

[0199] The oil inlet groove 311 extends downward in the height direction of the oil suction box 31. More preferably, in the height direction of the oil suction box 31, the width of the oil inlet groove 311 gradually increases from bottom to top.

[0200] like Figure 1 , Figure 2 , Figure 5-4 , Figure 5-5 , Figure 5-6 , Figure 5-7 As shown, the first liquid storage cavity 201 includes a liquid processing cavity 201W and a liquid receiving cavity 201U with an opening at the top.

[0201] The first cleaning chamber 101 and the liquid receiving chamber 201U are respectively arranged in the height direction of the cleaning device (the lower opening of the first cleaning chamber 101 faces the upper opening of the liquid receiving chamber 201U), and the first cleaning chamber 101 and the liquid processing chamber 201W are staggered (that is, the lower opening of the first cleaning chamber 101 and the upper opening of the liquid processing chamber 201W are staggered) to prevent the liquid in the first cleaning chamber 101 from falling into the liquid processing chamber 201W.

[0202] The liquid processing chamber 201W has a first end wall 2011 and a second end wall 2012 disposed opposite to each other. The first end wall 2011, the second end wall 2012 and the two side walls of the liquid processing chamber 201W form the inner cavity of the liquid processing chamber 201W.

[0203] K partitions 5 are fixed in the liquid processing chamber 201W, where K ≥ 1.

[0204] Each partition 5 is fixedly connected to both side walls of the liquid processing chamber 201W, thereby dividing the inner cavity of the liquid processing chamber 201W into K+1 sub-cavities that are independently set and connected in sequence when viewed from the top direction.

[0205] The side wall of the sub-cavity (i.e., the first sub-cavity 201A) adjacent to the first end wall 2011 and / or the first end wall 2011 are provided with an inlet 2010 that communicates with the liquid outlet of the liquid receiving cavity.

[0206] A first oil-water separation device is provided in at least one sub-cavity other than the sub-cavity adjacent to the first end wall 2011 (i.e., the first sub-cavity 201A). For example, the first oil-water separation device can be provided in the second sub-cavity 201B and the third sub-cavity 201C (only the oil suction device 3 is shown in the figure).

[0207] The side wall of the sub-cavity adjacent to the second end wall 2012 and / or the second end wall 2011 are provided with water outlets.

[0208] The outlet pipe 401 is connected to the oil-water separator cavity 201W to form an outlet. The outlet is located on the side wall of the sub-cavity adjacent to the second end wall 2012 and / or on the second end wall 2011. The outlet is located near the bottom surface of the oil-water separator cavity 201W or on the bottom surface of the oil-water separator cavity 201W.

[0209] Preferably, the partition 5 is spaced apart from the top / bottom surface of the liquid treatment chamber 201W, thereby forming an opening above / below the partition 5 that connects the two sub-cavities on both sides of the partition 5.

[0210] Preferably, the bottom end of the partition 5 closest to the first end wall 2011 extends to the bottom surface of the liquid processing chamber 201W, and the top end of the partition 5 closest to the first end wall 2011 is spaced apart from the top surface of the liquid processing chamber 201W, thereby forming an opening above the partition 5 connecting two sub-cavities on both sides of the partition 5. The height of the top end of the partition 5 closest to the first end wall 2011 is greater than the height of the top ends of the other partitions 5.

[0211] Each partition 5 is spaced apart. Each partition 5 can be arranged parallel to the first end wall 2011 and the second end wall 2012.

[0212] The bottom end of the other partition 5 extends to the bottom surface of the liquid treatment chamber 201W, or the bottom end of the other partition 5 is spaced apart from the bottom surface of the liquid treatment chamber 201W.

[0213] like Figure 5-4 As shown, in one embodiment, the bottom and top ends of each partition 5 are spaced apart from the liquid processing chamber 201W, so that channels connecting each sub-chamber are formed above and below the partition 5.

[0214] like Figure 5-5As shown, in another embodiment, the bottom end of the partition 5 closest to the first end wall 2011 extends to the bottom surface of the liquid processing chamber 201W. The top end of the partition 5 closest to the first end wall 2011 (i.e., the partition 5 serving as the wall of the first sub-chamber 201A) is spaced apart from the top surface of the liquid processing chamber 201W, thereby forming an opening above the partition 5 connecting the two sub-chambers on both sides of the partition 5. The height of the top end of the partition 5 closest to the first end wall 2011 is greater than the height of the top ends of the other partitions 5.

[0215] like Figure 5-6 As shown, in another embodiment, the bottom end of the partition 5 closest to the first end wall 2011 extends to the bottom surface of the liquid processing chamber 201W, and the top end of the partition 5 closest to the first end wall 2011 (i.e., the partition 5 that serves as the wall of the first sub-cavity 201A) is spaced apart from the top surface of the liquid processing chamber 201W, thereby forming an opening above the partition 5 that connects the two sub-cavities on both sides of the partition 5; the height of the partition 5 decreases sequentially from the first end wall 2011 to the second end wall 2012.

[0216] like Figure 6-1 , Figure 6-2 , Figure 6-3 The diagram shows a schematic representation of the air outlet device according to an embodiment of the present invention. The first air outlet device 4 includes a first air outlet device housing body 4A forming a closed structure, a first planar air guide plate 411, a second planar air guide plate 412, and a sealing side plate 42. The outlet of the drying fan 4B is connected to the airflow inlet 44 of the first air outlet device housing body 4A (e.g., located at the end of the first air outlet device housing body 4A). The drying fan 4B can be a Ritz fan.

[0217] The first air outlet device housing body 4A has an axis, and the cross-section of the first air outlet device housing body 4A perpendicular to the axis is an arc shape. That is, the air outlet device 4 housing of this application includes two parts: one part is an arc-shaped surface housing (e.g., a cylinder) with holes cut in the side wall (opening side wall through holes), and the other part includes a first planar air guide plate 411, a second planar air guide plate 412, and two sealing side plates 42 that intersect after extending upward from the side wall through holes. Each sealing side plate 42 is connected to the two air guide plates and the arc-shaped surface housing, so that the first planar air guide plate 411, the second planar air guide plate 412, and the two sealing side plates 42 form a protruding structure extending outward from the arc-shaped surface housing. The first planar air guide plate 411, the second planar air guide plate 412, and the two sealing side plates 42 together with the arc-shaped surface housing form a sealing structure.

[0218] The length direction of the first planar air guide plate 411 and the length direction of the second planar air guide plate 412 are both parallel to the axis.

[0219] One end of the first planar air guide plate 411 and one end of the second planar air guide plate 412 are respectively connected to the main body 4A of the first air outlet device housing.

[0220] Both the first planar air guide plate 411 and the second planar air guide plate 412 extend outward from the main body 4A of the first air outlet device housing, such that the other ends of the first planar air guide plate 411 and the other ends of the second planar air guide plate 412 are connected to each other, thereby forming a V-shaped structure. The sealing side plates 42 are installed on both sides of the opening of the V-shaped structure.

[0221] The intersection of the first planar air guide plate 411 and the second planar air guide plate 412 forms an airflow outlet 43. The extension directions of the first planar air guide plate 411 and the second planar air guide plate 412 both pass through the surface of the strip metal element 200 located in the running channel 200A.

[0222] like Figure 1 , Figure 2 As shown, the base 100A is fixed with a second cleaning chamber 102 with a lower opening and a second liquid storage chamber 202 with a higher opening. The second cleaning chamber 102 and the second liquid storage chamber 202 are correspondingly arranged in the height direction of the cleaning device (i.e., the lower opening of the second cleaning chamber 102 and the upper opening of the second liquid storage chamber 202 are arranged facing each other). In the running direction of the strip metal element 200, the second cleaning chamber 102 is located downstream of the first cleaning chamber 101.

[0223] The cleaning device also includes a second rinsing mechanism 302 for rinsing the surface of the strip metal element 200 in the second cleaning chamber 102.

[0224] The inner cavity of the second liquid storage chamber 202 is connected to the water inlet of the second flushing mechanism 302 through the second connecting pipe 402.

[0225] Preferably, the first cleaning chamber 101 is correspondingly arranged with the first liquid storage chamber 201, the second cleaning chamber 102 is correspondingly arranged with the second liquid storage chamber 202, and each first cleaning chamber 101 and each second cleaning chamber 102 is independently arranged.

[0226] Each first cleaning chamber 101 has a corresponding first blowing chamber 103 on its downstream side. The first blowing chamber 103 is equipped with a first blower 103A for blowing off the liquid on the surface of the strip metal component 200. The inner cavity of the first blowing chamber 103 is connected to the liquid inlet of the first rinsing mechanism 301.

[0227] The base 100A is fixed with a second cleaning chamber 102 located downstream of the first cleaning chamber 101; the first cleaning chamber 101 and the second cleaning chamber 102 are not in communication with each other;

[0228] The cleaning device also includes a second rinsing mechanism 302 for rinsing the surface of the strip metal element 200 in the second cleaning chamber 102.

[0229] The inner cavity of the second cleaning chamber 102 is connected to the liquid inlet of the second rinsing mechanism 302.

[0230] Preferably, the first cleaning chambers 101 and the second cleaning chambers 102 are not connected to each other.

[0231] Preferably, a second blowing chamber 104 is provided on the downstream side of each second cleaning chamber 102, and a second blower 104A is provided in the second blowing chamber 104 for blowing off the liquid on the surface of the strip metal element 200; the inner cavity of the second blowing chamber 104 is connected to the liquid outlet of the second rinsing mechanism 301.

[0232] Water recovered from the first liquid storage chamber 201 after oil-water separation can be returned to the first cleaning chamber 101 through the first connecting pipe 401, and used to rinse the surface of the strip metal element 200 (hereinafter referred to as "the element") through the first rinsing mechanism outlet 301A of the first rinsing mechanism 301; or, after flowing out of the first liquid storage chamber 201, it passes through the intermediate connecting pipes 401A, 3B, and the second oil-water separation device (i.e., another oil-water separation is performed, which can be an existing oil-water separation device or a device with the same structure as the first oil-water separation device), and then returns to the first cleaning chamber 101 through the first connecting pipe 401.

[0233] Water recovered from the second liquid storage chamber 202 can flow back to the second cleaning chamber 102 through the second connecting pipe 402, and then rinse the surface of the component through the second rinsing mechanism 302. The rinsing mechanism in this application can be a structure of pipe and nozzle.

[0234] Based on the same inventive concept, the present invention also provides a cleaning method using the above-described cleaning apparatus, the cleaning method comprising:

[0235] Step A: Use the scraping device 1 to scrape the surface of the strip metal element 200.

[0236] Step B: Rinse the surface of the strip metal component 200 with a rinsing solution at a preset temperature (the liquid at a certain temperature is convenient for removing surface grease).

[0237] Step C: Clean the surface of the strip metal element 200 using the brush device 2, and continuously rinse the brush 24 of the brush device 2 with a rinsing liquid, wherein the rinsing liquid is clean water or a mixture of clean water and cleaning agent.

[0238] Step D: Rinse the surface of the strip metal component 200 with clean water.

[0239] Step E: Dry the surface of the strip metal element 200 using the first air outlet device 4.

[0240] Preferably, the step between step C and step D further includes:

[0241] Step C1: Use a scraping device to scrape the surface of the strip metal element 200.

[0242] More preferably, the step between step C1 and step D further includes:

[0243] Step C2: Use the first fan 103A to blow off the liquid on the surface of the strip metal element 200.

[0244] The strip metal element 200 may be a steel strip or a saw blade.

[0245] The first air outlet device 4 is also connected to a heating device for heating the airflow in the inner cavity of the first air outlet device 4.

[0246] The embodiments of the present invention are further described below. The present invention designs a multi-stage cleaning device.

[0247] The first and second stages of treatment use the same methods and can employ rinsing devices with identical structures. The third stage involves air blowing. The fourth and fifth stages also use the same methods and can employ rinsing devices with identical structures. The sixth stage is a drying device. The cavities corresponding to the first and second stages are not interconnected; the cavities corresponding to the fourth and fifth stages are also not interconnected.

[0248] The first-level processing method includes steps A, B, C1, and C2.

[0249] Step A: In the first cleaning chamber 101, a scraping method is used to remove the thicker oil film and grease from the steel belt. Specifically, a stainless steel spring pressure device (i.e., a scraping device) is used, pressing two pieces of wool felt into a groove formed by two nylon plates. The stainless steel spring pressure device is installed and fixed at the inlet and outlet of the water tank. The steel belt to be cleaned is inserted between the two wool felt pieces. The abrasion resistance, soft material, and sealing properties of the wool felt scrape away the thicker grease and water from the steel belt, thus completing the initial cleaning of the steel belt. The water tank is sealed to prevent cross-contamination with the next stage.

[0250] Step B: After scraping, heat the water mixed with cleaning agent to 60 degrees Celsius and use 1.2 MPa high-pressure water at a 45-degree angle to rinse and soften the thin film of oil and grease on the steel strip. A 1.2 MPa high-pressure water pump with a fan-shaped nozzle designed at a 45-degree angle can be used to spray and soften the steel strip. The cleaning solution can contain cleaning agent and 70-degree hot water.

[0251] Step C: In the first cleaning chamber 101, after the above-mentioned scraping treatment, the steel strip is thoroughly scrubbed with a mixture of water containing cleaning agent and staggered brushes. An interlaced brush design can be used, with small nozzles installed on the brushes to continuously spray water onto them for a layered scrubbing process.

[0252] Step C1: In the first cleaning chamber 101, after the above brush treatment, the steel belt is passed through the scraping device located at the outlet of the first cleaning chamber 101 to remove surface moisture as much as possible and prevent moisture from entering the next stage.

[0253] The third-level processing method includes step C2.

[0254] Step C2: In the first blowing chamber 103, the first blower 103A blows off the liquid on the surface of the strip metal element 200. In step C2, a high-pressure water-cutting blower is used, with one blower at the top and one at the bottom, blowing water at a certain angle downwards and upwards into the water-blocking chamber. This water-blocking chamber is used to separate the rinsing water chamber (composed of each of the first cleaning chambers 101) and the cleaning water chamber (composed of each of the second cleaning chambers 102) to reduce cross-contamination between the rinsing water and the cleaning water. The water in the water-blocking chamber is relatively clean and can therefore be returned to the first rinsing mechanism for reuse.

[0255] The fourth-level processing method includes step D.

[0256] Step D: Use a high-flow water pump and a circular nozzle designed with a 60-degree inclination to rinse the steel strip.

[0257] The sixth-level processing method includes step E.

[0258] Step E: Dry the steel strip using a high-pressure Ritz blower containing a heating element. A Ritz blower is used as the power source, and a drying air knife with a temperature control system is fabricated to provide high-pressure air to the 30-degree, 0.05mm drying air knife for drying the steel strip.

[0259] The steel belt runs at a speed of 17-18 m / min. In order to achieve a better cleaning effect at a faster steel belt running speed, two rinsing water chambers are set up (the water chambers corresponding to the first and second stages), and two cleaning water chambers are set up (the water chambers corresponding to the fourth and fifth stages).

[0260] Additionally, the pH level can be detected and displayed inside the water tank. If the pH value exceeds the threshold, it indicates that there are too many impurities, and the water needs to be replaced or replenished. Existing pH detection devices and automatic water replenishment devices can be used.

[0261] This invention has been verified to have better cleaning effect, lower water change frequency, and is conducive to resource conservation.

[0262] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
