Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of push-pull pickling, and in particular relates to a rinsing tank for a push-pull pickling line. BACKGROUND

[0002] In the metal processing industry, the pickling line is a crucial link, mainly used for removing oxides, rust and other contaminants on the surface of the strip steel to improve the surface quality of the strip steel and the subsequent processing performance.

[0003] At present, the existing pickling tank usually adopts a fixed size of the inlet and outlet, which brings many inconveniences in actual application. Specifically, since the thickness and width of the strip steel may vary due to different production needs, the fixed size of the inlet and outlet is not sufficient when processing different specifications of strip steel. When the strip steel is thin, the excessively large inlet and outlet may cause excessive leakage of acid liquid, not only wasting the acid liquid resources, but also possibly causing environmental pollution. Conversely, when the strip steel is thick, the excessively small inlet and outlet may increase the resistance of the strip steel entering and exiting the pickling tank, and even cause damage to the equipment.

[0004] In view of the above problems, a rinsing tank for a push-pull pickling line is designed. CONTENT OF THE INVENTION

[0005] The embodiments of the present application provide a rinsing tank for a push-pull pickling line to solve the problem that the size of the inlet and outlet of the existing pickling tank is fixed and cannot be adjusted according to the thickness of the strip steel in the related art.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0026] The embodiments of the present application provide a push-pull type pickling line rinsing tank, which can solve the problem that the existing pickling tank in the related art has fixed inlet and outlet sizes and cannot be adjusted according to the thickness of the strip steel.

[0027] Please refer to Figures 1-3 A push-pull type pickling line rinsing tank comprises: a pickling tank 1, which has a chamber 2 for pickling of strip steel inside;

[0028] A cover plate 3 is arranged on the pickling tank 1, and through holes 4 are arranged at both ends of the pickling tank 1, the top of the through hole 4 is open, and the through hole 4 is used for the inlet and outlet of the strip steel; two containing grooves 5 are arranged at the bottom of the cover plate 3 in opposite directions, the containing groove 5 is in communication with the through hole 4, and an adjusting plate 6 is arranged inside the containing groove 5, the adjusting plate 6 comprises: a sealing plate 61 slidingly arranged inside the through hole 4, and a lifting piece 62 arranged on the containing groove 5, the lifting piece 62 is connected with the sealing plate 61 and is used for driving the sealing plate 61 to lift, so as to adjust the size of the through hole 4.

[0029] In the pickling process, the strip steel needs to enter from one end of the pickling tank 1 through hole 4 and exit from the other end through hole 4. At this time, the sealing plate 61 of the adjusting plate 6 is in a completely raised state, so that the size of the through hole 4 is maximized, facilitating the smooth entry and exit of the strip steel.

[0030] When the strip steel enters the pickling tank 1, in order to prevent acid leakage and ensure pickling effect, the size of the through hole 4 needs to be adjusted according to the thickness of the strip steel. At this time, the sealing plate 61 is driven to descend by the lifting piece 62 until the sealing plate 61 tightly fits the upper and lower surfaces of the strip steel. Since the sealing plate 61 can slide inside the through hole 4, it can be adjusted left and right according to the width of the strip steel, ensuring the sealing effect.

[0031] In the chamber 2 of the pickling tank 1, the acid reacts chemically with the surface of the strip steel, removing oxides and rust. At this time, the cover plate 3 prevents acid from evaporating and splashing, ensuring the safety and hygiene of the pickling process.

[0032] After pickling is completed, the lifting piece 62 drives the sealing plate 61 to rise again, and the strip steel exits the pickling tank 1 from the through hole 4 and enters the next process.

[0033] By adjusting the size of the through hole 4, precise adjustment can be made according to strip steels of different thicknesses, ensuring that the acid does not leak too much, thereby improving the pickling efficiency, so that the rinsing tank can adapt to strip steels of different specifications and thicknesses, improving the versatility and flexibility of the equipment.

[0034] The sealing plate 61 can effectively prevent acid from evaporating and splashing, reducing waste of acid and reducing environmental pollution. The closing of the cover plate 3 and the adjustment of the sealing plate 61 can ensure the safety and hygiene of the pickling process, avoiding direct contact between the operator and the acid.

[0035] The length and width of the sealing plate 61 in the present embodiment are respectively matched with the length and width of the through hole 4.

[0036] The width of the sealing plate 61 is designed to match the width of the through hole 4, in order to ensure that when the sealing plate 61 is lowered and fitted on the edge of the through hole 4, a tight seal can be formed to prevent acid leakage.

[0037] At the same time, the length of the sealing plate 61 should be large enough to cover at least part or even all of the through hole 4 in the opening direction. In this way, regardless of the width of the strip steel, the sealing plate 61 can be tightly fitted on the upper and lower surfaces of the strip steel through the adjustment of the lifting piece 62, ensuring the sealing effect in the pickling process.

[0038] The design of the sealing plate 61 matching the width of the through hole 4 ensures that the sealing plate 61 can be tightly fitted on the edge of the through hole, effectively preventing acid leakage. Since the length of the sealing plate 61 can cover part or all of the through hole 4 in the opening direction, the rinsing tank can adapt to strip steels of different widths, improving the versatility and flexibility of the equipment.

[0039] In one embodiment, the lifting member 62 comprises a plurality of electric push rods 621 arranged at the top of the accommodating groove 5, and a sealing strip 622 is arranged on the piston rod of the electric push rods 621 on the same side.

[0040] The plurality of electric push rods 621 are evenly distributed at the top of the accommodating groove 5, and the electric push rods 621 on the same side, i.e., the same side relative to the through hole 4, are connected by a common connection to ensure that they can move synchronously.

[0041] A sealing strip 622 is commonly connected to the piston rod of the electric push rods 621 on the same side. The sealing strip 622 can maintain close connection with the piston rod when the electric push rod 621 is retracted, and moves together with the piston rod.

[0042] The bottom end of the sealing strip 622 is connected to the sealing plate 61 by welding. In this way, when the electric push rod 621 is retracted, the sealing strip 622 will drive the sealing plate 61 to rise and fall.

[0043] When the size of the through hole 4 needs to be adjusted, the control system sends instructions to the electric push rod 621 to start the retraction movement. As the piston rod of the electric push rod 621 extends or retracts, the sealing strip 622 moves and drives the sealing plate 61 to rise and fall. By accurately controlling the retraction amount of the electric push rod 621, the position of the sealing plate 61 can be accurately adjusted, thereby achieving accurate control of the size of the through hole 4.

[0044] The chamber 2 in the embodiment has two filter screens 7 arranged inside.

[0045] The main function of the filter screen 7 is to filter out impurities and particulate matter in the pickling solution, which may come from oxides, rust or other contaminants on the surface of the strip. This avoids blockage of the liquid supply mechanism 8 and the liquid discharge valve 9.

[0046] In order to facilitate replacement and maintenance, the two filter screens 7 are placed in abutment in the chamber 2. When the filter screen 7 is blocked or worn to a certain extent, the operator can conveniently remove it for cleaning or replacement.

[0047] Preferably, the chamber 2 in the embodiment is provided with a liquid supply mechanism 8 inside, which is used to inject liquid into the chamber 2; the liquid supply mechanism 8 comprises a liquid supply pipe 81 arranged inside the chamber 2, a plurality of liquid supply pipes 82 are arranged on the liquid supply pipe 81, the liquid supply pipes 82 are U-shaped, and a plurality of liquid outlets are formed on the liquid supply pipes 82; one end of the liquid supply pipe 82 is provided with a communication pipe 83, and one end of the communication pipe 83 is connected with an external liquid supply pipe.

[0048] The liquid supply pipe 81 is arranged inside the chamber 2, usually along the length direction of the chamber. The liquid supply pipe 81 serves as the main delivery pipe for the pickling solution, and its material should be corrosion-resistant and pressure-resistant to ensure stable delivery of the pickling solution.

[0049] The liquid delivery pipe 82 branches from the liquid supply pipe 81 and is arranged along the length of the liquid supply pipe 81. The U-shaped design of the liquid delivery pipe 82 can ensure a certain pressure balance of the pickling solution in the liquid delivery pipe 82, allowing the pickling solution to enter the chamber 2 more uniformly and stably.

[0050] A plurality of liquid outlets are provided on the liquid delivery pipe 82, which are used to uniformly pour the pickling solution into the chamber 2. The size and number of the liquid outlets should be reasonably designed according to the flow rate and injection pressure of the pickling solution to ensure smooth pouring of the pickling solution into the chamber 2.

[0051] One end of the liquid delivery pipe 82 is connected to an external liquid supply pipe through a communication pipe 83. The communication pipe 83 serves as an input channel for the pickling solution to ensure stable delivery of the pickling solution.

[0052] Further, the pickling tank 1 in the present embodiment is provided with a liquid discharge valve 9 at the bottom, which is in communication with the chamber 2.

[0053] The liquid discharge valve 9 is arranged at the bottom of the pickling tank 1 and is located at the lowest point of the chamber 2, which can ensure that the waste liquid in the chamber 2 can be completely discharged without dead corners during the liquid discharge process.

[0054] The liquid discharge valve 9 is usually made of corrosion-resistant and wear-resistant materials such as stainless steel or special alloy. At the same time, in order to facilitate operation and maintenance, the liquid discharge valve 9 is usually designed as a manual or electric control, and is equipped with corresponding sealing devices to ensure that there is no leakage in the closed state.

[0055] The other end of the liquid discharge valve 9 is connected to an external waste liquid treatment pipe. During the liquid discharge process, the waste liquid is transported to the external waste liquid treatment system for further treatment through the liquid discharge pipe.
