Description

Technical Field

[0001] The utility model belongs to the technical field of oil removal devices, in particular to a strip steel alkali solution oil removal device. Background Art

[0002] Strip alkali solution is mainly used in the cleaning process of cold-rolled strip steel. Its function is to remove the emulsion, iron ions and metal ions remaining on the strip steel after rolling, keep the strip steel clean, and prevent damage to the furnace rolls and surface defects.

[0003] Existing strip alkali liquid oil removal devices usually include a degreasing tank, which allows the strip to fully contact with the strip alkali liquid through immersion to ensure the cleaning effect of the strip. At the same time, it is also equipped with a tension roller to ensure the degreasing effect and surface quality of the strip.

[0004] In the current existing technology, although the provision of a tension roller can provide an initial tension to the strip entering the degreasing tank, thereby ensuring the degreasing effect and surface quality of the strip and improving the consistency of the degreasing effect, strips of different materials and thicknesses have different requirements for tension during the degreasing process. When the tension is relatively small, it is easy for thicker or harder strips to remain flat. When the tension is relatively large, it is easy for thinner or softer strips to be overstretched.

[0005] Therefore, a strip steel alkali liquor degreasing device is proposed in response to the above problems. Utility Model Content

[0006] In order to make up for the shortcomings of the existing technology and solve the problem that strip steels of different materials and thicknesses have different tension requirements during the degreasing process, when the tension is relatively small, it is easy for thicker or harder strip steels to be difficult to keep flat, and when the tension is relatively large, it is easy for thinner or softer strip steels to be overstretched, a strip steel alkali liquid degreasing device is proposed.

[0007] The technical solution adopted by the utility model to solve the technical problem is as follows: the strip steel alkali liquid degreasing device of the utility model comprises a degreasing tank;

[0008] Two tension rollers are symmetrically installed on the inner side of the oil removal tank, and water outlet pipes are installed on both sides of the tension rollers. The ends of the water outlet pipes close to the tension rollers are slidably installed inside the oil removal tank, and the ends of the water outlet pipes away from the tension rollers are slidably installed on one side of the oil removal tank. A first adjustment component is provided at the end of the water outlet pipe away from the tension roller, and a water inlet pipe and a connecting plate are fixedly installed on one side of the oil removal tank.

[0009] Preferably, the first adjusting component includes a lifting plate arranged at the end of the water outlet pipe away from the tension roller, and a second adjusting component is provided on both sides of the lifting plate, a screw rod is threadedly installed in the middle of the lifting plate, and guide rods are slidably installed at both ends of the lifting plate, and the guide rods are fixedly installed on one side of the oil removal tank, a limit block is fixedly installed on the top end of the screw rod, and a motor is provided at the bottom end of the screw rod, and the motor is connected to the external power supply through a wire; it can change the tension provided by the tension roller to the strip when the feeding speed of the strip is changed due to replacement of strip steel of different specifications or other factors.

[0010] Preferably, the second adjusting component includes a driving tooth plate arranged on one side of the lifting plate, and a toothed rod is meshedly installed on one side of the driving tooth plate, a threaded rod is fixedly installed on one end of the toothed rod, and a blocking rod is fixedly installed on one end of the threaded rod, and the blocking rods are slidably installed on the inner wall of the water flow trough, and the water flow trough is opened on the inner wall of the spherical regulating valve, and the spherical regulating valve is fixedly installed on the outer wall of the water inlet pipe or the connecting plate, and a threaded barrel is fixedly installed on one side of the spherical regulating valve, and the threaded rod is threadedly installed on the inner wall of the threaded barrel; it can reduce the tension of the tension roller on the strip when the discharge speed of the strip increases, and the blocking rod moves toward the direction close to the water flow trough, thereby reducing the flow inside the outlet pipe and the water inlet pipe.

[0011] Preferably, the cross-section of the water flow trough is set to be square, and the distance between the side of the water flow trough close to the blocking rod and the side away from the blocking rod is greater than the distance between the two ends of the blocking rod; this can ensure that there is always a gap between one end of the blocking rod and one side of the water flow trough, thereby improving the stability and reliability of the device.

[0012] Preferably, a threaded line is provided on the inner wall of the spherical regulating valve near one end of the flow-blocking rod, and a straight portion without a threaded line is provided between the threaded line and the spherical regulating valve; this can prevent the threaded rod from moving into the water flow groove along the threaded line provided between the degreasing pool screw rod and the inner wall of the water flow groove, thereby avoiding the problem of corrosion of the threaded line on the outer wall of the threaded rod by the alkali liquid flowing in the outlet pipe or the water inlet pipe, thereby extending the service life of the threaded rod.

[0013] Preferably, the difference between the longest distance and the shortest distance from the toothed rod to one side of the driving tooth plate is greater than the distance between the two ends of the flow-blocking rod; this enables one side of the toothed rod to always engage with the driving tooth plate, thereby avoiding the problem that when one end of the toothed rod moves to the side of the driving tooth plate, the movement of the driving tooth plate is difficult to drive the toothed rod to rotate, resulting in the device being difficult to subsequently adjust the flow in the water outlet pipe and the water inlet pipe through the second adjusting component.

[0014] Beneficial effects of the utility model:

[0015] The utility model provides a device for removing oil from steel strips using alkali solution. By setting a first adjusting component, when the feeding speed of the steel strips is changed due to replacement of steel strips of different specifications or other factors, the staff can start the motor, so that the motor drives the tension roller to move through the lead rod, the lifting plate and the connecting plate, thereby changing the tension provided by the tension roller to the steel strips, avoiding the problem that when the tension is relatively small, thicker or harder steel strips are difficult to keep flat, and when the tension is relatively large, thinner or softer steel strips are easily overstretched, thereby ensuring the processing quality of the steel strips. In addition, appropriate tension can also reduce the shaking of the steel strips during transportation, thereby increasing the contact area between the alkali solution and the surface of the steel strips, and accelerating the removal of oil stains.

[0016] The utility model provides a strip alkali liquid oil removal device. By setting a second adjusting component, when the first adjusting component adjusts the position of the tension roller, the lifting plate can change the flow in the water outlet pipe and the water inlet pipe by driving the tooth plate, the toothed rod, the threaded rod and the flow blocking rod, so that when the strip discharge speed increases, the tension of the tension roller on the strip is reduced. At this time, the flow blocking rod moves in the direction close to the water flow trough, thereby reducing the flow inside the water outlet pipe and the water inlet pipe, avoiding the reduction of the consumption of the strip alkali liquid when the strip feeding speed is accelerated, and maintaining the circulation flow speed of the strip alkali liquid is likely to cause waste of resources. In addition, a faster strip feeding speed is likely to accelerate the flow speed of the alkali liquid in the degreasing tank, and a faster alkali liquid circulation flow speed will further increase the flow speed of the alkali liquid in the degreasing tank, which is likely to cause lateral or longitudinal fluctuations of the strip, thereby causing wavy defects on the strip surface, affecting the processing quality of the strip, improving resource utilization, and reducing the influence of the alkali liquid flow on the strip surface, thereby improving the processing quality of the strip.

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Specific examples are given below.

[0025] See also Figures 1 to 3 , the utility model provides a strip steel alkali liquor degreasing device, comprising a degreasing tank 1;

[0026] Two tension rollers 2 are symmetrically installed on the inner side of the degreasing tank 1, and water outlet pipes 3 are installed on both sides of the tension rollers 2. The ends of the water outlet pipes 3 close to the tension rollers 2 are slidably installed inside the degreasing tank 1, and the ends of the water outlet pipes 3 away from the tension rollers 2 are slidably installed on one side of the degreasing tank 1. A first adjusting component is provided at the end of the water outlet pipe 3 away from the tension rollers 2, and a water inlet pipe 4 and a connecting plate 5 are fixedly installed on one side of the degreasing tank 1.

[0027] Further, such as Figure 1 and Figure 2As shown, the first adjustment component includes a lifting plate 6 arranged at one end of the water outlet pipe 3 away from the tension roller 2, and a second adjustment component is provided on both sides of the lifting plate 6. A screw rod 7 is threadedly installed in the middle of the lifting plate 6, and a guide rod 8 is slidably installed at both ends of the lifting plate 6. The guide rod 8 is fixedly installed on one side of the oil removal tank 1, and a limit block 9 is fixedly installed on the top of the screw rod 7. A motor 10 is provided at the bottom end of the screw rod 7. The motor 10 is connected to the external power supply through a wire. By setting the first adjustment component, when the feeding speed of the strip steel is changed due to the replacement of strip steel of different specifications or other factors, the staff can start the motor 10, so that the motor 10 drives the tension roller 2 to move through the screw rod 7, the lifting plate 6 and the connecting plate 5, thereby changing the tension provided by the tension roller 2 to the strip steel, avoiding the problem that when the tension is relatively small, it is easy for thicker or harder strip steel to remain flat, and when the tension is relatively large, it is easy for thinner or softer strip steel to be overstretched, thereby ensuring the processing quality of the strip steel. In addition, the appropriate tension can also reduce the shaking of the strip steel during transportation, thereby increasing the contact area between the alkali solution and the strip steel surface, and accelerating the removal speed of oil stains. The model of motor 10 is 80A6S-M02430.

[0028] Further, such as Figures 1 to 3 As shown, the second adjusting component includes a driving tooth plate 11 arranged on one side of the lifting plate 6, and a toothed rod 12 is meshed and installed on one side of the driving tooth plate 11, and a threaded rod 13 is fixedly installed on one end of the toothed rod 12, and a choke rod 14 is fixedly installed on one end of the threaded rod 13, and the choke rod 14 is slidably installed on the inner wall of the water flow groove 16, and the water flow groove 16 is opened on the inner wall of the ball regulating valve 15, and the ball regulating valve 15 is fixedly installed on the outer wall of the water inlet pipe 4 or the connecting plate 5. A threaded barrel 17 is fixedly installed on one side of the ball regulating valve 15, and the threaded rod 13 is threadedly installed on the inner wall of the threaded barrel 17. By setting the second adjusting component, when the first adjusting component adjusts the position of the tension roller 2, the lifting plate 6 can change the outlet pipe through the driving tooth plate 11, the toothed rod 12, the threaded rod 13 and the choke rod 14. 3 and the flow in the water inlet pipe 4, so that when the strip discharge speed increases, the tension of the strip by the tension roller 2 is reduced, and at this time the flow blocking rod 14 moves toward the direction close to the water flow trough 16, thereby reducing the flow inside the water outlet pipe 3 and the water inlet pipe 4, avoiding the reduction of the consumption of the strip alkali solution when the strip feeding speed is accelerated, and maintaining the circulation flow rate of the strip alkali solution is likely to cause waste of resources. In addition, a faster strip feeding speed is likely to accelerate the flow rate of the alkali solution in the degreasing tank 1, and a faster alkali solution circulation flow rate will further increase the flow rate of the alkali solution in the degreasing tank 1, which is likely to cause lateral or longitudinal fluctuations of the strip, thereby causing wavy defects on the strip surface, affecting the problem of strip processing quality, improving resource utilization, and reducing the influence of alkali solution flow on the strip surface, thereby improving the strip processing quality.

[0029] Further, such as Figure 2 and Figure 3 As shown, the cross-section of the water flow trough 16 is set to be square, and the distance between the side of the water flow trough 16 close to the blocking rod 14 and the side away from the blocking rod 14 is greater than the distance between the two ends of the blocking rod 14, so that there is always a gap between one end of the blocking rod 14 and one side of the water flow trough 16, avoiding the blocking rod 14 completely closing the water flow trough 16, making it difficult for the strip alkali liquid in the degreasing tank 1 to circulate, resulting in a decrease in the degreasing efficiency of the device, thereby improving the stability and reliability of the device.

[0030] Further, such as Figure 2 and Figure 3 As shown, a threaded line is provided on the inner wall of the spherical regulating valve 15 near one end of the flow-blocking rod 14, and a straight portion without a threaded line is provided between the threaded line and the spherical regulating valve 15, so that the threaded rod 13 will not move along the threaded line provided between the threaded barrel 17 and the inner wall of the spherical regulating valve 15 into the water flow groove 16, thereby avoiding the problem of the alkali solution flowing in the water outlet pipe 3 or the water inlet pipe 4 corroding the threaded line on the outer wall of the threaded rod 13, thereby extending the service life of the threaded rod 13.

[0031] Further, such as Figure 2 and Figure 3 As shown, the difference between the longest distance and the shortest distance from the toothed rod 12 to one side of the driving tooth plate 11 is greater than the distance between the two ends of the flow-blocking rod 14, which can ensure that one side of the toothed rod 12 is always engaged with the driving tooth plate 11, avoiding the problem that when one end of the toothed rod 12 moves to the side of the driving tooth plate 11, the movement of the driving tooth plate 11 is difficult to drive the toothed rod 12 to rotate, resulting in the device being difficult to adjust the flow in the water outlet pipe 3 and the water inlet pipe 4 through the second adjusting component later, thereby improving the stability and reliability of the second adjusting component.

[0032] Working Principle: When the strip needs to be degreased, the strip is passed through the gap between the degreasing tank 1 and the tension roller 2. At this time, the staff opens the water inlet pipe 4 to allow the strip alkali solution to fill the degreasing tank 1. Then, the water outlet pipe 3 is opened to keep the strip alkali solution in the degreasing tank 1 circulating, avoiding local concentration differences and compensating for alkali solution consumption in a timely manner.

[0033] When it is necessary to adjust the feeding speed of the strip according to the material of the strip or other factors, the motor 10 can be started, so that the motor 10 drives the screw rod 7 to rotate, the screw rod 7 drives the lifting plate 6 to move, the lifting plate 6 drives the connecting plate 5 to move, and the connecting plate 5 drives the tension roller 2 to move, thereby adjusting the tension provided by the tension roller 2 to the strip according to actual conditions, thereby improving the oil removal effect of the oil outlet device and the quality of the strip surface. At the same time, the lifting plate 6 drives the driving tooth plate 11 to move, the driving tooth plate 11 drives the toothed rod 12 to rotate, the toothed rod 12 drives the threaded rod 13 to rotate, so that the threaded rod 13 moves along the thread line of the inner wall of the threaded barrel 17, and the threaded rod 13 drives the flow control rod 14 to move, thereby changing the flow rate of the outlet pipe 3 and the inlet pipe 4, reducing resource waste while reducing the flow rate of the strip alkali solution in the degreasing tank 1, thereby improving the surface quality of the strip.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
