Description
Technical Field
[0001] This utility model relates to the field of strip steel rinsing technology, specifically to a multi-segment staggered jet rinsing mechanism for strip steel. Background Technology
[0002] In the steel production and processing industry, strip steel, as an important basic material, is widely used in many industries such as automobile manufacturing, home appliance production, and construction decoration. As these industries continuously raise their product quality requirements, the demands on the surface quality of strip steel are also becoming increasingly stringent. After a series of processing steps including hot rolling, cold rolling, galvanizing, and coating, various impurities remain on the surface of strip steel, such as iron oxide scale, grease, acid, and metal powder. If these impurities are not thoroughly removed, they will seriously affect the subsequent processing performance of the strip steel and the quality of the final product. For example, in the coating process, the presence of impurities will lead to decreased coating adhesion, resulting in defects such as coating peeling and flaking; in the welding process, impurities will affect the welding quality, reducing the strength and toughness of the weld joint. Therefore, in the strip steel production process, the rinsing stage becomes a key process to ensure the surface quality of the strip steel. Highly efficient rinsing equipment can thoroughly remove impurities from the surface of the strip steel, providing a high-quality substrate for subsequent processing, thereby meeting the quality requirements of different industries for strip steel products and enhancing the competitiveness of enterprises in the market.
[0003] Currently, some strip steel rinsing equipment on the market adopts a single-stage rinsing method, rinsing the strip steel with only one set of nozzles. This results in limited coverage and difficulty in thoroughly removing stubborn impurities adhering to the strip steel surface. In particular, impurities are prone to remain in some small gaps and uneven areas, leading to incomplete cleaning of the strip steel surface and affecting product quality. Furthermore, when rinsing the strip steel directly and vertically, the water flow impact force is easily too large, which may damage the strip steel surface. Therefore, this utility model provides a multi-segment staggered spray rinsing mechanism for strip steel. Utility Model Content

This solves the problems of some strip steel rinsing equipment on the market that uses a single-stage rinsing method, rinsing the strip steel with only one set of nozzles. This results in limited coverage and difficulty in thoroughly removing stubborn impurities from the strip steel surface. Impurities are particularly prone to remain in small gaps and uneven areas, leading to incomplete cleaning of the strip steel surface and affecting product quality. Furthermore, directly rinsing the strip steel vertically can easily cause excessive water flow impact, which may damage the strip steel surface.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-segment staggered jet rinsing mechanism for strip steel, comprising a rinsing shell, wherein the rinsing shell is equipped with a rinsing mechanism for conveying the strip steel, the rinsing mechanism comprising:

[0013] Beneficial effects
[0014] This utility model provides a multi-segmented staggered jet rinsing mechanism for steel strips. Compared with the prior art, it has the following advantages:
[0015] Firstly, this utility model employs a multi-stage rinsing design. Initial rinsing is performed by nozzles, followed by secondary rinsing by the first and second rinsing nozzles, gradually improving the cleaning effect on the strip steel. This more thoroughly removes impurities and residual acid from the strip steel surface, improving surface quality and meeting higher production process requirements. The first and second rinsing nozzles are inclined and positioned opposite each other, forming a cross-jet water flow, expanding the rinsing coverage area, effectively eliminating rinsing dead zones, and ensuring that all parts of the strip steel surface are thoroughly cleaned, improving the uniformity and comprehensiveness of rinsing. Furthermore, the flexible adjustment of the positions of the first and second rinsing nozzles enhances the equipment's adaptability to different working conditions, improving its versatility. Additionally, the inclined rinsing nozzles reduce the excessive pressure on the strip steel caused by direct vertical rinsing.
[0016] Secondly, the nozzles of the first and second rinsing nozzles of this utility model are staggered, which ensures that the water flow impacts the strip from different angles and positions, covering every part of the strip surface, thereby avoiding uneven rinsing and making the water flow distribution on the strip surface more extensive. The water flow sprayed from each nozzle has a certain coverage area. After being staggered, the coverage areas of adjacent nozzles overlap, forming a continuous and uniform water flow coverage layer, ensuring that every point in the width direction of the strip can be impacted by the water flow, avoiding local residues caused by incomplete coverage.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4 This utility model provides a technical solution: a multi-segment staggered spray rinsing mechanism for strip steel, including a rinsing shell 1, on which a rinsing mechanism for conveying strip steel is provided, the rinsing mechanism including:
[0024] The collection component includes a water tank body 2 fixed to the top of the rinsing shell 1, a rinsing chamber 3 opened inside the rinsing shell 1, an inclined slide 301 opened at the bottom of the rinsing chamber 3, a drain shell 302 fixed to the lower end of the inclined slide 301, and a filter screen plate 304 connected by a sliding component inside the drain shell 302.
[0025] The rinsing assembly includes a cavity shell 501 fixed to one side of the upper end of the rinsing chamber 3. The lower end face of the cavity shell 501 is evenly distributed with nozzles 502. The inner wall of the rinsing chamber 3 is provided with a guide groove 6. The inside of the guide groove 6 is provided with a first shell 601 connected by an opening and closing assembly. The lower end of the first shell 601 is evenly distributed with first rinsing nozzles 602 that are inclined.
[0026] In a preferred embodiment, the rinsing shell 1 has inlet ports 201 on both sides, and an inwardly inclined baffle 202 is fixed inside the inlet port 201. The inner wall of the rinsing chamber 3 is evenly distributed with support rollers 4, and the upper end of the water tank body 2 is provided with a water inlet. The inlet port 201 is used to feed the strip steel. The strip steel is mainly pulled out from the rinsing mechanism by the coiler, and the rinsed strip steel is rolled into a coil and supported by the support rollers 4. The baffle 202 also prevents water or impurities from splashing out of the rinsing shell 1 from the inlet port 201 during the feeding process.
[0027] When the strip moves under the traction of the coiler, the support roller 4 rotates accordingly to provide support for the strip and reduce the friction between the strip and the bottom of the rinsing chamber 3.
[0028] In a preferred embodiment, the sliding assembly includes a sliding groove 303 formed on the inner wall of the drain housing 302. A filter plate 304 is slidably connected inside the sliding groove 303. One end of the filter plate 304 is fixed to a mounting plate 305, whose inner sidewall is fitted to one end of the drain housing 302. A pair of bolts are provided inside the mounting plate 305, allowing for detachable connection with the drain housing 302. The filter plate 304 is used to filter and collect impurities from the discharged wastewater. During the strip steel rinsing process, the rinsed wastewater flows into the rinsing chamber 3 and then into the drain housing 302 along the inclined sliding groove 301 at the bottom of the rinsing chamber 3. When the wastewater passes through the filter plate 304 inside the drain housing 302, impurities are intercepted and filtered by the filter plate 304. The filtered water is discharged from the drain housing 302. When it is necessary to remove impurities from the filter plate 304... During cleaning, unscrew the bolts on the mounting plate 305, pull the filter screen plate 304 out of the sliding groove 303, clean the impurities, and then reinstall the filter screen plate 304 and tighten the bolts to fix it. The filter screen plate 304 can filter and collect impurities in the rinsing wastewater, preventing impurities from entering the subsequent water circulation system or being discharged into the environment, ensuring the cleanliness and reusability of water resources, and reducing environmental pollution. Through the design of the sliding component, the filter screen plate 304 can be easily pulled out and reinstalled from the drain housing 302, which facilitates the cleaning of impurities on the filter screen plate 304, reduces maintenance difficulty and workload, and improves the efficiency of equipment use. In addition, the inclined sliding groove 301 design allows dirty water and impurities to flow automatically to the drain housing 302 without the need for an additional power device. It uses gravity to achieve water flow guidance, which is energy-saving, environmentally friendly, simple in structure, and highly stable.
[0029] In a preferred embodiment, a first conduit 5 is disposed at the upper end of the cavity shell 501. The first conduit 5 extends to the outside of the rinsing shell 1 and connects to the water tank body 2. The opening and closing assembly includes a motor 7 fixed at the top of the rinsing chamber 3. A drive gear 701 is fixed at the output end of the motor 7. A first gear rod 702 and a second gear rod 703 mesh on both sides of the drive gear 701, and the first gear rod 702 and the second gear rod 703 are obliquely symmetrical about the drive gear 701. The two ends of the first shell 601 are slidably connected inside the guide groove 6. One end of the first gear rod 702 is fixedly connected to the first shell 601. A second shell 605 is disposed on the symmetrical side of the first shell 601 about the drive gear 701, and the second shell 605 is slidably connected to the guide groove 6. The lower end surface of the second shell 605 is uniform. The system includes a second rinsing nozzle 606, and both the first rinsing nozzle 602 and the second rinsing nozzle 606 are inclined with their inclination directions opposite to each other. A hose 603 is provided on one side of the first outer shell 601. The lower end of the water tank body 2 extends into the rinsing chamber 3 and is fixed with a second conduit 604. The second conduit 604 and the hose 603 are in a flow connection. The nozzle 502 is used to perform the first step of rinsing and pressurizing on the incoming strip steel. Then, the first rinsing nozzle 602 and the second rinsing nozzle 606 perform a second rinsing on the strip steel. The water in the water tank body 2 flows into the cavity outer shell 501 through the first conduit 5 and is then sprayed out from the nozzle 502 on the lower end face of the cavity outer shell 501 to perform the first step of rinsing and pressurizing on the strip steel entering the rinsing chamber 3 from the feed inlet 201, removing most of the impurities and residues from the surface of the strip steel.
[0030] Furthermore, the motor 7 starts, and its output drives the drive gear 701 to rotate. The drive gear 701 meshes with the first gear rod 702 and the second gear rod 703, which are obliquely symmetrically distributed on both sides, thereby driving the first gear rod 702 and the second gear rod 703 to move. Since the first gear rod 702 is fixedly connected to the first outer shell 601, and the two ends of the first outer shell 601 are slidable within the guide groove 6, the movement of the first gear rod 702 causes the first outer shell 601 to slide within the guide groove 6. Similarly, the second gear rod 703 causes the second outer shell 605 to slide within the guide groove 6. The lower end of body 2 extends into the rinsing chamber 3 through a second conduit 604 and a hose 603. Water enters the first outer shell 601 through the second conduit 604 and hose 603, and is sprayed out from the first rinsing nozzles 602, which are evenly distributed and inclined at the lower end of the first outer shell 601. At the same time, water also enters the second outer shell 605 and is sprayed out from the second rinsing nozzles 606, which are evenly distributed at the lower end of the second outer shell 605. The first rinsing nozzles 602 and the second rinsing nozzles 606 are inclined in opposite directions, and perform a second rinse on the strip steel that has been initially rinsed by the nozzles 502, further cleaning the surface of the strip steel and ensuring that there are no dead corners in the cleaning.
[0031] Through a multi-stage rinsing design, the strip is first initially rinsed by nozzle 502, followed by a secondary rinse by the first rinsing nozzle 602 and the second rinsing nozzle 606. This gradually improves the cleaning effect of the strip, more thoroughly removing impurities and residual acid from the strip surface, improving the surface quality of the strip, and meeting higher production process requirements. The first rinsing nozzle 602 and the second rinsing nozzle 606 are inclined and positioned opposite each other, forming a cross-jet water flow, expanding the rinsing coverage area, effectively eliminating rinsing dead corners, and ensuring that all parts of the strip surface are thoroughly cleaned, improving the uniformity and comprehensiveness of rinsing. Furthermore, the positions of the first rinsing nozzle 602 and the second rinsing nozzle 606 can be flexibly adjusted to enhance the equipment's adaptability to different working conditions and improve its versatility.
[0032] Furthermore, the nozzles of the first rinsing nozzle 602 and the second rinsing nozzle 606 are staggered, which ensures that the water flow impacts the strip from different angles and positions, covering every part of the strip surface, thereby avoiding uneven rinsing and making the water flow distribution on the strip surface more extensive. The water flow sprayed from each nozzle has a certain coverage area. After being staggered, the coverage areas of adjacent nozzles overlap, forming a continuous and uniform water flow coverage layer, ensuring that every point in the width direction of the strip can be impacted by the water flow, avoiding local residues caused by incomplete coverage.
[0033] All of the aforementioned conduits use a water pump to extract water from inside the main body of the water tank. The water pump model is PUN-201, which is existing technology and will not be described in detail.
[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0035] During operation, the strip steel is fed into the rinsing chamber 1 through the feed inlets 201 on both sides under the traction of the coiler. The inwardly inclined baffles 202 fixed inside the feed inlets 201 guide the strip steel smoothly into the rinsing chamber 3, while preventing water or impurities from splashing out. After entering the rinsing chamber 3, the strip steel is placed on evenly distributed support rollers 4. As the strip steel moves, the support rollers 4 rotate accordingly, providing support and reducing friction.
[0036] Water in the main body 2 of the water tank flows into the hollow outer shell 501 through the first conduit 5, and then is sprayed out from the nozzles 502 evenly distributed on the lower end face of the hollow outer shell 501 to perform the first step of rinsing and spraying the strip steel, initially removing surface impurities and residues. Afterwards, the motor 7 starts, and its output end drives the drive gear 701 to rotate. The drive gear 701 meshes with the first gear rod 702 and the second gear rod 703 that are obliquely symmetrically distributed on both sides, thereby driving the first outer shell 601 and the second outer shell 605 to slide in the guide groove 6. At the same time, the second conduit 604 at the lower end of the main body 2 supplies water to the first outer shell 601 and the second outer shell 605 through the hose 603. Water is sprayed from the first conduit 502 that is obliquely set at the lower end of the first outer shell 601. The rinsing nozzle 602 and the second rinsing nozzle 606 at the lower end of the second housing 605 spray out, and the two are inclined in opposite directions with staggered nozzle distribution, to perform a second rinse on the strip steel after the initial rinsing, ensuring that there are no dead corners in the cleaning; the wastewater generated during the rinsing process flows into the rinsing chamber 3, and flows into the drain housing 302 along the inclined slide 301 at the bottom. After being filtered by the filter screen plate 304, impurities are intercepted, and the filtered water is discharged from the drain housing 302. When it is necessary to clean the filter screen plate 304, the bolts on the mounting plate 305 are unscrewed, and it is pulled out from the sliding groove 303. After cleaning, it is reinstalled and the bolts are tightened to fix it. Finally, the rinsed strip steel is sent out from the feed port on the other side under the traction of the coiler and is coiled into a coil.
