Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of strip steel processing equipment, and in particular to a strip steel rinsing tank. Background Technology
[0002] After pickling, steel strip needs to be rinsed. The effectiveness of rinsing determines the amount of residue on the steel strip surface. Excessive residue will affect subsequent production processes. For example, in rolling, excessive surface residue will affect the composition of the emulsion. Therefore, how to efficiently remove residue from the steel strip surface is a key aspect of the rinsing process, while also considering energy conservation.
[0003] The existing pickling tank and rinsing tank are separated by two pairs of squeeze rollers, with a pre-rinsing spray pipe between the squeeze rollers. This serves two purposes: first, to rinse away residual acid from the strip surface; and second, to coat the strip surface with liquid, isolating it from air and preventing re-oxidation. To prevent excessive acid buildup, the squeeze rollers are replaced very frequently, approximately once a week, taking half an hour each time. Reducing the replacement frequency results in poor squeezing efficiency, with more acid being carried into the rinsing tank, increasing rinsing difficulty, water consumption, and surface quality, thus affecting subsequent processes.
[0004] Meanwhile, with the development of the steel industry, the strength requirements for strip steel are getting higher and higher, which leads to an increase in alloying elements in the strip steel, making pickling and rinsing difficult. In particular, for strip steel with high silicon content, the compounds generated after pickling are very sticky and have strong adhesion, making them difficult to rinse. Currently, the rinsing water pump used in the spray water circuit during the rinsing process has a low working pressure. In order to reduce the residue on the surface of the strip steel and obtain better surface quality, more water needs to be consumed. Utility Model Content

[0039] like Figure 1 As shown, this utility model provides a strip steel rinsing tank, which includes: a rinsing tank body 10, the rinsing tank body 10 having an inlet and an outlet, and forming a rinsing chamber 11 for holding rinsing liquid; an inlet squeeze roller group 20, the inlet squeeze roller 21 being located in the rinsing chamber 11 and at the inlet; an outlet squeeze roller group 30, the outlet squeeze roller 31 being located in the rinsing chamber 11 and at the outlet; and a plurality of rinsing spray assemblies 40, the rinsing spray assemblies 40 being located between the inlet squeeze roller 21 and the outlet squeeze roller 31, and the plurality of rinsing spray assemblies 40 being spaced apart along the conveying direction of the strip steel; wherein, both the inlet squeeze roller group 20 and the outlet squeeze roller group 30 have at least three pairs of squeeze rollers spaced apart along the conveying direction of the strip steel, and when at least three pairs of squeeze rollers in the squeeze roller group squeeze the strip steel, at least one pair of squeeze rollers is in a standby state and at least one pair of squeeze rollers is in a working state.
[0040] The strip rinsing tank of this utility model can extend the replacement cycle of the inlet squeeze roller and the outlet squeeze roller 31. The rinsing tank body 10 is equipped with at least three pairs of squeeze rollers at the inlet and outlet. During normal operation, some squeeze rollers can be put into operation while the others are in standby mode. When the squeeze rollers wear down and the squeezing effect deteriorates, the squeeze rollers in standby mode are switched to work until all squeeze rollers wear down and are then replaced. This can extend the squeeze roller replacement cycle by more than double and improve the unit's operating rate. In special cases, all of them can be put into use at the same time for even better squeezing effect.
[0041] The following will provide a detailed description of the specific structure of each part of the steel strip rinsing tank described in this utility model, as well as the position and connection relationship between each part.
[0042] The steel strip rinsing tank has a rinsing tank body 10, such as Figure 1 As shown, the left end of the rinsing tank body 10 is the inlet end, which is connected to the pickling tank. A rinsing chamber 11 is formed inside the rinsing tank body 10. The right end of the rinsing tank body 10 is the outlet end, which is connected to a blower and a dryer. The strip steel that has been pickled in the pickling tank enters the rinsing chamber 11 from the inlet end of the rinsing tank body 10 and is rinsed in the rinsing chamber 11 by the rinsing solution and rinsing tools. Afterwards, it enters the blower and dryer through the outlet end of the rinsing tank body 10 for edge blowing and drying.
[0043] In the rinsing chamber 11, such as Figure 1 As shown, an inlet squeeze roller group 20 is provided at the inlet, which squeezes out the acid carried out from the pickling tank on the strip. Along the conveying direction of the strip, the inlet squeeze roller group 20 has at least three pairs of inlet squeeze rollers 21 spaced apart. Each pair of inlet squeeze rollers 21 includes two opposing squeeze rollers arranged one above the other, with the strip sandwiched between the two squeeze rollers. When the at least three pairs of inlet squeeze rollers 21 in the inlet squeeze roller group 20 are squeezing the strip, at least one pair of inlet squeeze rollers 21 is in a standby state, and at least one pair of inlet squeeze rollers 21 is in a working state; that is, some inlet squeeze rollers 21 are clamped and performing the squeezing operation, while others are in a standby state. The inlet squeeze rollers 21 in the standby state can be switched to the working state after the inlet squeeze rollers 21 wear out, realizing the switching between states, thereby extending the roller changing cycle of the entire inlet squeeze roller group 20. In this embodiment, the inlet squeeze roller group 20 includes three pairs of inlet squeeze rollers 21. When performing inlet squeeze operation, two of them can be put into operation while the other is in standby mode. The inlet squeeze roller 21 in standby mode is used to replace the more worn inlet squeeze roller 21 in time for the squeeze operation.
[0044] In the rinsing chamber 11, such as Figure 1As shown, an outlet squeeze roller group 30 is provided at the outlet, through which the washed strip steel is squeezed dry. Along the conveying direction of the strip steel, the outlet squeeze roller group 30 has at least three pairs of outlet squeeze rollers 31 arranged at intervals. Each pair of outlet squeeze rollers 31 includes two opposing squeeze rollers arranged one above the other, with the strip steel sandwiched between the two squeeze rollers. When at least three pairs of outlet squeeze rollers 31 in the outlet squeeze roller group 30 are squeezing the strip steel, at least one pair of outlet squeeze rollers 31 is in a standby state, and at least one pair of outlet squeeze rollers 31 is in a working state; that is, some outlet squeeze rollers 31 are clamped and performing the squeezing operation, while others are in a standby state. The outlet squeeze rollers 31 in the standby state can be switched to the working state after the outlet squeeze rollers 31 wear out, realizing the switching between states, thereby extending the roller changing cycle of the entire outlet squeeze roller group 30. In this embodiment, the outlet squeeze roller group 30 includes three pairs of outlet squeeze rollers 31. When performing outlet squeeze operation, two of them can be put into operation, while the other is in standby mode. The outlet squeeze roller 31 in standby mode is used to replace the outlet squeeze roller 31 with more severe wear in a timely manner to perform the squeeze operation.
[0045] In the rinsing chamber 11, such as Figure 1 As shown, multiple rinsing spray assemblies 40 are provided between the inlet squeeze roller group 20 and the outlet squeeze roller group 30. The rinsing spray assemblies 40 rinse the surface of the strip by spraying high-pressure rinsing liquid toward the strip. The multiple rinsing spray assemblies 40 are spaced apart along the conveying direction of the strip. Each rinsing spray assembly 40 has multiple pairs of rinsing spray beams 50 spaced apart along the conveying direction of the strip. Each pair of rinsing spray beams 50 includes an upper rinsing spray beam and a lower rinsing spray beam. The upper rinsing spray beam has multiple nozzles with their openings tilted downwards, and the lower rinsing spray beam has multiple nozzles with their openings tilted upwards. Each pair of rinsing spray beams 50 in each rinsing spray assembly 40 is connected to a rinsing spray supply pipe 51 that can draw rinsing liquid from the rinsing chamber 11. A rinsing water pump 52 is provided on the rinsing spray supply pipe 51. In this embodiment, along the conveying direction of the strip steel, the rinsing chamber 11 is sequentially provided with a first rinsing spray assembly 41, a second rinsing spray assembly 42, a third rinsing spray assembly 43, a fourth rinsing spray assembly 44 and a fifth rinsing spray assembly 45, and each rinsing spray assembly 40 has three pairs of rinsing spray beams 50.
[0046] The following will provide a more detailed description of the structure and technical effects of the preferred embodiment of the steel strip rinsing tank of this utility model.
[0047] According to one embodiment of the present invention, such as Figure 1As shown, within the inlet squeeze roller group 20, a pair of squeeze spray beams 22 are provided between two pairs of adjacent inlet squeeze rollers 21. The squeeze spray beams 22 are connected to squeeze spray supply pipes 23 that can draw rinsing liquid from the rinsing chamber 11. Each pair of squeeze spray beams 22 includes an upper squeeze spray beam and a lower squeeze spray beam. The upper squeeze spray beam has multiple nozzles with downward-facing openings, and the lower squeeze spray beam has multiple nozzles with upward-facing openings. In this embodiment, two pairs of squeeze spray beams 22 are provided between the three pairs of inlet squeeze rollers 21. The squeeze spray beams 22 assist the inlet squeeze rollers 21 in the strip deacidification operation, thereby improving the removal effect of residual acid on the strip.
[0048] According to one embodiment of the present invention, such as Figure 1 As shown, within the rinsing spray assembly 40 near the inlet squeeze roller group 20, the rinsing spray supply pipe 51 is connected to the squeeze spray supply pipe 23, and the connected rinsing spray supply pipe 51 and squeeze spray supply pipe 23 share a rinsing water pump 52. In this embodiment, the rinsing spray supply pipe 51 on the first rinsing spray assembly 41 is connected to the squeeze spray supply pipe 23, and both share a rinsing water pump 52; by supplying liquid to both units simultaneously through a single rinsing water pump 52, the equipment structure can be simplified and investment costs reduced while ensuring the rinsing effect.
[0049] According to one embodiment of the present invention, such as Figure 1 As shown, at least one pair of rinsing rollers 54 are provided between each pair of adjacent rinsing spray assemblies 40. Each rinsing roller 54 is located behind the rinsing spray beam 50 within each rinsing spray assembly 40 to squeeze the strip steel dry after spray rinsing. Each pair of rinsing rollers 54 includes two rinsing rollers 54 arranged opposite each other, with the strip steel sandwiched between the two rinsing rollers 54. In this embodiment, four pairs of rinsing rollers 54 are provided between the five rinsing spray assemblies 40. Since the strip steel undergoes multi-stage rinsing, squeezing the residual rinsing liquid on the surface of the strip steel after each spray rinsing is beneficial for the next stage of spray rinsing, thereby improving the multi-stage rinsing effect of the strip steel.
[0050] According to one embodiment of the present invention, such as Figure 1As shown, among the rinsing water pumps 52 on each rinsing spray supply pipe 51, at least one rinsing water pump 52 is a high-pressure plastic pump 53 with a supply pressure of 0.8 MPa, while the supply pressure of the remaining rinsing water pumps 52 is 0.4 MPa. In this embodiment, the rinsing spray supply pipe 51 connected to the fourth rinsing spray assembly 44 is equipped with a high-pressure plastic pump 53, while the rinsing water pumps 52 connected to the first rinsing spray assembly 41, the second rinsing spray assembly 42, the third rinsing spray assembly 43, and the fifth rinsing spray assembly 45 are conventional water pumps; the pressure of the rinsing liquid in the fourth rinsing spray assembly 44 is increased from the original 0.4 MPa to 0.8 MPa, which can improve the rinsing effect and reduce the residue on the surface of the strip steel.
[0051] According to one embodiment of the present invention, such as Figure 1 As shown, within the rinsing spray assembly 40 near the outlet squeeze roller group 30, at least one pair of rinsing spray beams 50 are connected to a condensate supply pipe 60. The other end of the condensate supply pipe 60 is connected to a condensate tank 62. A condensate pump, a high-pressure stainless steel metal pump 61, is installed on the condensate supply pipe 60, with a supply pressure of 1 MPa to 1.25 MPa. In this embodiment, the fifth rinsing spray assembly 45 has three pairs of rinsing spray beams 50. The first two pairs of rinsing spray beams 50 are connected to a rinsing spray supply pipe 51, and the last pair of rinsing spray beams 50 are connected to a condensate supply pipe 60. The condensate supply pipe 60 is equipped with a high-pressure stainless steel metal pump 61 with a supply pressure of 1 MPa to 1.25 MPa. While replenishing water to the rinsing tank, the condensate supply pipe 60 increases the water replenishment pressure of the rinsing tank from the original 0.4 MPa to 1 MPa to 1.25 MPa through the high-pressure stainless steel metal pump 61, thereby improving the rinsing effect of the outlet strip steel and significantly reducing the residue on the surface of the strip steel.
[0052] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
