Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, and more specifically, to a micro-oxidation passivation liquid spraying device for the surface of steel strip after plating. Background Technology

[0002] Steel strip is a type of flat, coiled steel produced through hot or cold rolling processes. Produced in continuous coils, it boasts high strength and toughness, a smooth surface, and uniform thickness, making it widely used in automotive bodies, appliance panels, building cladding, and packaging materials. After galvanizing / zinc-aluminizing, steel strip undergoes passivation treatment to form a micron-level protective film, enhancing corrosion resistance and coating adhesion. It is a crucial basic material for modern industry. Passivation typically involves spraying a passivating solution onto the steel strip surface using a spraying device. However, existing spraying devices have fixed nozzles, making adjustment difficult and limiting the spraying range. This necessitates repositioning the strip for comprehensive, all-around spraying, which is challenging due to its weight and the difficulty of movement, resulting in inconvenient equipment operation.

[0003] Therefore, a micro-oxidation passivation liquid spraying device for the surface of steel strip after plating is proposed to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a micro-oxidation passivation liquid spraying device for the surface of steel strip after plating, so as to solve the problem that the nozzle of the prior art spraying device is fixed and inconvenient to adjust, resulting in a limited spraying range.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a micro-oxidation passivation liquid spraying device for the surface of steel strip after plating, comprising...

[0006] place pool;

[0007] A spraying assembly, wherein the spraying assembly is disposed at the back of the placement tank;

[0008] The spraying assembly includes a liquid storage tank, a nozzle, a traversing mechanism, and a support. The liquid storage tank is located at the back of the placement pool. A liquid pump is fixedly installed on the top of the liquid storage tank. The suction end of the liquid pump is fixedly connected to a connecting pipe. The end of the connecting pipe away from the liquid pump is fixedly connected to the interior of the liquid storage tank. The output end of the liquid pump is fixedly connected to a flexible hose. The end of the flexible hose away from the liquid pump is fixedly connected to the interior of the nozzle. The traversing mechanism is fixedly installed on the inner surface of the placement pool. A support is fixedly installed on the top of the traversing mechanism. The nozzle is located at one end of the support via a direction adjustment mechanism.

[0009] The transverse mechanism includes a slide groove, one end of which is fixedly mounted with a No. 1 motor. A lead screw is rotatably mounted inside the slide groove, one end of which is fixedly connected to the output end of the No. 1 motor. A movable block is slidably mounted inside the slide groove, and the interior of the movable block is threadedly connected to the outer surface of the lead screw.

[0010] The direction adjustment mechanism includes a second motor and a rotating shaft. The second motor is fixedly installed on one side of one end of the bracket. One end of the rotating shaft is fixedly connected to the output end of the second motor, and the other end of the rotating shaft is rotatably connected to one end of the bracket. The outer surface of the rotating shaft is fixedly connected to the top of the nozzle.

[0011] It also includes a recycling component, which is located below the placement pool.

[0012] The recycling assembly includes a leak outlet, a collection box, a discharge outlet, a pull plate, and a filter membrane. The leak outlet is located at the bottom of the placement pool, the collection box is installed at the bottom of the placement pool, the discharge outlet is located on one side of the collection box, the pull plate is slidably installed inside the collection box, and the filter membrane is detachably installed inside the pull plate.

[0013] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0014] In the above scheme, a placement tank and a spraying assembly are set up. Passivating liquid is added to the storage tank, and the strip steel is placed inside the placement tank. The liquid pump is started, and the liquid pump draws the passivating liquid from the storage tank through the connecting pipe and then delivers it to the spray head through the hose. The spray head sprays the liquid onto the surface of the strip steel. The first motor is started, which drives the lead screw to rotate, causing the movable block to slide in the slide groove. This moves the spray head through the bracket. The second motor is started, which drives the rotating shaft to rotate, thereby rotating the spray head. Through the above structure, the position and orientation of the spray head can be adjusted, and the spraying range can be flexibly adjusted to achieve the effect of flexible use of the device.

[0015] The system incorporates a recycling component. Excess passivating liquid sprayed onto the steel strip surface flows into a collection tank through a drain outlet. After being filtered by a filter membrane, the liquid eventually accumulates at the bottom of the collection tank. The collected passivating liquid can then be discharged through a drain outlet. This structure enables the recycling of the sprayed passivating liquid, facilitating its reuse and achieving resource conservation. Attached Figure Description
