Description

Technical Field

[0001] This utility model relates to the field of emulsion technology, specifically to an emulsion tank for a galvanized strip steel rolling mill. Background Technology

[0002] In the production of galvanized strip steel, the rolling mill is one of the key pieces of equipment, and the emulsion, as an important cooling and lubricating medium in the rolling process, directly affects the quality of the rolled products and the operating efficiency of the rolling mill. However, traditional emulsion tank structures often have unreasonable design problems and are difficult to adapt to the complex and ever-changing working environment of galvanized strip steel rolling mills.

[0003] According to a published design of an emulsion tank (publication number: CN217457261U), the tank bottom is equipped with rail wheels compatible with railway tracks, facilitating movement and eliminating the need for a separate flatbed trolley for transport, making it more economical and convenient. Furthermore, a baffle plate with a high perimeter and low center is formed at the bottom of the chamber, allowing dirt to be washed away along the baffle plate during cleaning, making cleaning convenient and effective. Simultaneously, a cooling water pipe is installed to effectively reduce the temperature of the emulsion inside the chamber, providing better protection for the emulsion pump station.

[0004] The above-mentioned application, through the design of track wheel assembly and guide plate, has optimized the ease of use and cleaning effect of emulsion tank to a certain extent, but it still does not fully solve the problem of the adaptability of emulsion tank in complex working environment, and the structure is too complicated and the maintenance cost is high. Therefore, we propose a compression molding equipment for rubber product production. Utility Model Content

[0005] To overcome the above-mentioned defects, the present invention provides an emulsion tank for a galvanized strip steel rolling mill, which solves the technical problem that the existing emulsion tank has an unreasonable structure and is difficult to adapt to the complex working environment of the galvanized strip steel rolling mill.

[0006] According to one aspect, at least one embodiment of the present invention provides an emulsion tank for a galvanized strip steel rolling mill, comprising: a tank body, a bottom plate fixedly connected to the top of the tank body, a rain shield provided on the side of the tank body, a connecting pipe fixedly connected to the side of the tank body, a pump body fixedly connected to the end of the connecting pipe away from the tank body, a first-level partition provided on the inner wall of the tank body, a second-level partition provided on the inner wall of the tank body, a third-level partition provided on the inner wall of the tank body, a parabolic partition provided on the inner wall of the tank body, an airfoil guide vane provided on the inner wall of the tank body, a sludge collection trough provided at the bottom of the tank body, and a pneumatic slag discharge valve provided at the bottom of the sludge collection trough.

[0007] For example, in at least one embodiment of this utility model, an emulsion tank for a galvanized strip steel rolling mill further includes a pneumatic slag discharge valve, the interior of which is connected to the interior of the tank, and the interior of the pump body is connected to the interior of the tank. This facilitates the smooth flow of the emulsion between the tank and the pump body, ensuring that the emulsion can be effectively extracted and recycled.

[0008] Two parabolic baffles are provided, and they are symmetrical to each other along the vertical central axis of the box. The radius of curvature of the parabolic baffles is set to 1200 mm. This is beneficial for the parabolic baffles to guide and divert the emulsion, so that the emulsion can be more evenly distributed in the box, reducing dead zones and improving the utilization efficiency of the emulsion.

[0009] The airfoil guide vanes are arranged in pairs, and the airfoil guide vanes are symmetrical to each other along the vertical central axis of the box. This is beneficial for the airfoil guide vanes to further guide and rectify the emulsion, making the emulsion flow more smoothly, reducing turbulence and eddies, thereby reducing energy loss and improving the overall efficiency of the emulsion circulation system.

[0010] The rain shield is located above the pump body, and the side section of the sludge collection trough is set in a V shape. This helps the rain shield protect the pump body, prevents rainwater from directly wetting the pump body, and extends the service life of the pump body. At the same time, the V-shaped sludge collection trough can more effectively collect and discharge dirt from the bottom of the tank.

[0011] According to another aspect, at least one embodiment of this utility model also provides an emulsion tank for a galvanized strip steel rolling mill, comprising: a heat dissipation device, wherein the heat dissipation device is provided on the side of the tank body, the heat dissipation device includes a heat dissipation pipe, the heat dissipation pipe is fixedly connected to the side of the tank body, a liquid pump is provided on the circumferential surface of the heat dissipation pipe, a motor is fixedly connected to the side of the tank body, a drive gear is fixedly connected to the output shaft of the motor, a drive shaft is fixedly connected to the side of the tank body, a driven gear is provided on the circumferential surface of the drive shaft, a connecting column is fixedly connected to the side of the driven gear, a fan blade is fixedly connected to the end of the connecting column away from the driven gear, and a regulating valve is provided on the circumferential surface of the heat dissipation pipe. This facilitates the heat dissipation device to dissipate heat from the emulsion in the tank body in a timely manner, preventing the emulsion from deteriorating due to excessive temperature and affecting the rolling quality.

[0012] For example, in at least one embodiment of the present invention, an emulsion tank for a galvanized strip steel rolling mill is provided, which further includes a filter box. The filter box is provided on the circumferential surface of the heat dissipation pipe, and a filter plate is provided on the side of the filter box. This facilitates the filter box and the filter plate to perform preliminary filtration of the emulsion flowing into the heat dissipation pipe, remove any impurities and particulate matter that may be present, and prevent these impurities from clogging the heat dissipation pipe or affecting the heat dissipation effect.

[0013] The driving gear and driven gear mesh with each other, and the driving gear has more teeth than the driven gear. This difference in the number of teeth between the driving and driven gears helps to achieve a speed reduction and torque increase effect, allowing the fan blades to rotate at a more suitable speed. This, in turn, reduces energy consumption while ensuring heat dissipation efficiency. The number of connecting posts is set to several and arranged in a linear array along the side of the driven gear. The fan blade is located on the side of the heat sink. This arrangement helps the multiple connecting posts to stably support the fan blade and ensure that the fan blade remains balanced during rotation. At the same time, the linear array layout helps to evenly distribute the airflow.

[0014] The heat dissipation pipe has an S-shaped side section and penetrates the interior of the casing. This S-shaped heat dissipation pipe design increases the flow path and time of the emulsion within the heat dissipation pipe, allowing the emulsion to fully contact the heat dissipation pipe wall, thereby improving heat dissipation efficiency.

[0015] The beneficial effects of this utility model are as follows: In this invention, the overall structure of the emulsion tank is optimized through the cooperation of components such as the tank body, bottom plate, and rain shield. This makes the tank more adaptable to the actual working environment of the galvanized strip steel rolling mill, effectively preventing external factors such as rainwater from affecting the tank's interior and ensuring the stability of the emulsion's quality. Simultaneously, the design of the first-stage baffle, second-stage baffle, third-stage baffle, parabolic baffle, and airfoil guide vanes enables precise control of the emulsion's flow within the tank. This not only results in a more uniform distribution of the emulsion and reduces dead zones, but also lowers energy loss during flow, improving the overall efficiency of the emulsion circulation system and ultimately enhancing the production efficiency and product quality of the galvanized strip steel rolling mill.

[0016] In this invention, the effective heat dissipation of the emulsion is achieved through the cooperation of components such as the heat dissipation pipe, motor, and drive gear in the heat dissipation device. This prevents the emulsion from deteriorating due to excessive temperature, thereby ensuring the stability of the rolling process and the consistency of product quality. The heat dissipation pipe adopts an S-shaped layout, which not only increases the flow path of the emulsion and extends the heat dissipation time, but also achieves efficient heat conduction through its through-connection with the inside of the box. The motor drives the drive gear to rotate, which in turn drives the driven gear and fan blades to rotate. The resulting airflow accelerates the air flow on the surface of the heat dissipation pipe, further improving the heat dissipation efficiency. The addition of the filter box and filter disc effectively removes impurities and particulate matter from the emulsion, preventing these substances from clogging the heat dissipation pipe and ensuring the long-term stable operation of the heat dissipation system.

In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0022] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components.

Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] like Figures 1-5 As shown, this invention illustrates an emulsion tank for a galvanized strip steel rolling mill according to one embodiment of the present invention. The tank includes a body 1, a bottom plate 2 fixedly connected to the top of the body 1, a rain shield 3 on the side of the body 1, a connecting pipe 4 fixedly connected to the side of the body 1, a pump body 5 fixedly connected to the end of the connecting pipe 4 away from the body 1, a first-level partition 6, a second-level partition 7, a third-level partition 8, a parabolic partition 9, and an airfoil guide vane 10 on the inner wall of the body 1. A sludge collection trough 11 is located at the bottom of the body 1, and a pneumatic slag discharge valve 12 is located at the bottom of the sludge collection trough 11.

[0027] The pneumatic slag discharge valve 12 is connected to the inside of the housing 1, and the pump body 5 is connected to the inside of the housing 1. This facilitates the smooth flow of the emulsion between the housing 1 and the pump body 5, ensuring that the emulsion can be effectively extracted and recycled.

[0028] There are two parabolic baffles 9, which are symmetrical about each other along the vertical central axis of the box 1. The radius of curvature of the parabolic baffles 9 is set to 1,200 millimeters. This is beneficial for the parabolic baffles 9 to guide and divert the emulsion, so that the emulsion can be more evenly distributed in the box 1, reducing dead flow angles and improving the utilization efficiency of the emulsion.

[0029] The number of airfoil guide vanes 10 is set to several, in pairs. The airfoil guide vanes 10 are symmetrical about each other along the vertical central axis of the box 1. This is beneficial for the airfoil guide vanes 10 to further guide and rectify the emulsion, making the emulsion flow more smoothly, reducing turbulence and eddies, thereby reducing energy loss and improving the overall efficiency of the emulsion circulation system.

[0030] The rain shield 3 is located above the pump body 5, and the side section of the sludge collection tank 11 is set as V-shaped. This is beneficial for the rain shield 3 to protect the pump body 5, prevent rainwater from directly wetting the pump body 5, and extend the service life of the pump body 5. At the same time, the V-shaped sludge collection tank 11 can more effectively collect and discharge the dirt at the bottom of the tank 1.

[0031] This embodiment provides an emulsion tank for a galvanized strip steel rolling mill. Through the cooperation of components such as the tank body 1, the bottom plate 2, and the rain shield 3, the emulsion can be effectively stored and initially protected.

[0032] See in some examples Figures 1-5 The detailed working principle described above is as follows: After the emulsion enters the tank 1 from the pump body 5, it is first blocked and diverted by the first-stage baffle 6, the second-stage baffle 7, and the third-stage baffle 8. These baffles slow down the flow rate of the emulsion, allowing it to remain in the tank 1 for a longer time, thus facilitating the sedimentation of impurities and temperature equalization. Subsequently, the emulsion flows through the parabolic baffle 9. The special shape of the parabolic baffle 9 guides the emulsion again, allowing it to flow along a preset path, further reducing dead zones and ensuring that the emulsion in each area of ​​the tank 1 is effectively treated. At the same time, the airfoil guide vane 10 straightens the emulsion, allowing it to flow in a more stable state, reducing energy loss caused by turbulence and eddies, and improving the efficiency of the entire circulation system. During the flow of the emulsion, impurities gradually settle into the sludge collection tank 11 at the bottom of the tank 1. Since the side cross-section of the sludge collection tank 11 is V-shaped, it is more conducive to the collection of dirt. When it is necessary to clean the dirt, open the pneumatic slag discharge valve 12 to discharge the dirt in the sludge collection tank 11.

[0033] refer to Figures 1-5In some embodiments, an emulsion tank for a galvanized strip steel rolling mill further includes a heat dissipation device 13. The heat dissipation device 13 is provided on the side of the tank body 1. The heat dissipation device 13 includes a heat dissipation pipe 131, which is fixedly connected to the side of the tank body 1. A liquid pump 139 is provided on the circumferential surface of the heat dissipation pipe 131. A motor 132 is fixedly connected to the side of the tank body 1. A drive gear 133 is fixedly connected to the output shaft of the motor 132. A transmission shaft 134 is fixedly connected to the side of the tank body 1. A driven gear 135 is provided on the circumferential surface of the transmission shaft 134. A connecting column 136 is fixedly connected to the side of the driven gear 135. A fan blade 137 is fixedly connected to the end of the connecting column 136 away from the driven gear 135. A regulating valve 138 is provided on the circumferential surface of the heat dissipation pipe 131. This facilitates the heat dissipation device 13 to dissipate heat from the emulsion in the tank body 1 in a timely manner, preventing the emulsion from deteriorating due to excessive temperature and affecting the rolling quality.

[0034] A filter box 14 is provided on the circumferential surface of the heat pipe 131, and a filter plate 15 is provided on the side of the filter box 14. This facilitates the filter box 14 and the filter plate 15 to perform preliminary filtration of the emulsion flowing into the heat pipe 131, remove any impurities and particles that may be present, and prevent these impurities from clogging the heat pipe 131 or affecting the heat dissipation effect.

[0035] The driving gear 133 and the driven gear 135 mesh with each other. The driving gear 133 has more teeth than the driven gear 135. This difference in the number of teeth between the driving gear 133 and the driven gear 135 helps to achieve the effect of speed reduction and torque increase, allowing the fan blade 137 to rotate at a more suitable speed. This, in turn, reduces energy consumption while ensuring heat dissipation efficiency. The number of connecting posts 136 is set to a certain number and is arranged linearly along the side of the driven gear 135. The fan blade 137 is located on the side of the heat sink 131. This is conducive to the multiple connecting posts 136 being able to stably support the fan blade 137, ensuring that the fan blade 137 remains balanced during rotation. At the same time, the linear array layout helps to evenly distribute the airflow.

[0036] The side cross-section of the heat dissipation pipe 131 is set to S-shape, and the heat dissipation pipe 131 penetrates the interior of the housing 1. This is beneficial because the S-shaped heat dissipation pipe 131 design can increase the flow path and time of the emulsion in the heat dissipation pipe 131, so that the emulsion can fully contact the wall of the heat dissipation pipe 131, thereby improving the heat dissipation efficiency.

[0037] In this embodiment, the heat dissipation function of the emulsion in the box 1 is achieved through the cooperation between the heat dissipation pipe 131, motor 132 and drive gear 133 in the heat dissipation device 13.

[0038] In this embodiment, when the motor 132 starts, its output shaft drives the drive gear 133 to rotate. Since the drive gear 133 and the driven gear 135 mesh with each other, and the drive gear 133 has more teeth than the driven gear 135, according to the gear transmission principle, the driven gear 135 will rotate at a faster speed than the drive gear 133. When the driven gear 135 rotates, it drives the multiple connecting posts 136 in a linear array on its side to rotate, thereby causing the fan blades 137 fixed to the end of the connecting posts 136 away from the driven gear 135 to rotate. The rotation of the fan blades 137 generates airflow, which blows towards the heat sink 131. The heat sink 131 contains emulsion drawn from the housing 1. The airflow can accelerate the airflow speed around the heat sink 131, thereby accelerating the heat dissipation of the emulsion in the heat sink 131. Meanwhile, the S-shaped cross-section of the heat dissipation pipe 131 increases the flow path and time of the emulsion within the pipe, allowing for full contact between the emulsion and the wall of the pipe. This enables more efficient heat transfer from the emulsion to the pipe, which is then dissipated through heat exchange with the surrounding air. Furthermore, the filter box 14 and filter disc 15 on the circumferential surface of the heat dissipation pipe 131 provide preliminary filtration of the emulsion flowing into it, removing any impurities and particles. This prevents these impurities from clogging the pipe or affecting the heat dissipation effect, ensuring that the heat dissipation device 13 can continuously and stably dissipate heat from the emulsion within the housing 1.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
