A pull plate 3 is installed on the surface of the chamber 1, and a water storage tank 4 is placed on the upper surface of the chamber 1. A protective cover 5 is bolted to the outer surface of the chamber 1; the protective cover 5 can be disassembled to facilitate the addition of solution to the soaking chamber 6 and the observation of the soaking effect. The soaking chamber 6 is placed inside the chamber 1, and a pressure roller 61 is movably connected inside the soaking chamber 6. A guide roller 7 is movably connected inside the chamber 1, and a pressure roller is rotatably connected to the surface of the chamber 1. A filter plate 32 is fixedly connected to the surface of the pull plate 31, and a collection chamber 33 is fixedly connected to the surface of the filter plate 32. A water collection chamber 34 is opened inside the machine compartment 1, and a connecting groove 35 is opened on the inner wall of the water collection chamber 34. A drain outlet 36 is connected to the surface passage of the machine compartment 1. Through the connection between the machine compartment 1 and the support frame 2, the steel strip roll is conveniently placed and the steel strip is wound after processing under the action of the support frame 2. With the connection between the pull plate 3 and the filter plate 32, and the connection between the filter plate 32 and the collection chamber 33, the filtration of the rinsing liquid and the collection of impurities are achieved.
[0018] Furthermore, a through groove is provided inside the machine compartment 1, and the through groove extends through the surface of the machine compartment 1. The guide roller 7 is movably connected to the opposite sides of the machine compartment 1 through the through groove. Through the connection of the through groove on the machine compartment 1, the guide roller 7 and the through groove rotate to achieve the effect of limiting the position of the steel strip entering the machine compartment 1.
[0019] Furthermore, the filter plate 32 is inserted into the water collection chamber 34 via the pull plate 3. The filter plate 32 and the connecting groove 35 are slidably connected. The pressure plate 31 is arranged in two groups on both sides of the pull plate 3. The outer surfaces of the pressure plate 31 and the pull plate 3 are in contact. Through the connection between the pull plate 3 and the filter plate 32, and under the action of the filter plate 32, the liquid after rinsing the steel belt is filtered through the sliding connection between the filter plate 32 and the connecting groove 35.
[0020] Furthermore, the outer surface of the collection chamber 33 is arc-shaped. The collection chamber 33 acts on the lower half of the filter plate 32. The drain outlet 36 and the water collection chamber 34 are connected. Through the connection between the collection chamber 33 and the filter plate 32, the impurities filtered down from the filter plate 32 can be collected in a concentrated manner under the action of the collection chamber 33. Under the action of the drain outlet 36, the filtered liquid can be discharged.
[0021] Furthermore, the pressure rollers 61 are distributed in two groups on the surface of the immersion chamber 6. Through the connection between the immersion chamber 6 and the pressure rollers 61, the chemical solution used for zinc strip removal is conveniently stored under the action of the immersion chamber 6. Under the action of the pressure rollers 61, the steel strip and the solution are fully in contact, improving the operation performance of the process.
[0022] Furthermore, a high-pressure water pump 81 is installed on the surface of the machine compartment 1, and a flushing plate 8 is fixedly connected to the inside of the machine compartment 1 through a connecting plate. The high-pressure water pump 81 is connected to the water storage tank 4 through a water supply pipe. The inside of the flushing plate 8 is hollow, and nozzles are distributed on the surface of the flushing plate 8. The high-pressure water pump 81 is connected to the nozzles on the flushing plate 8 through the water supply pipe. With the action of the high-pressure water pump 81, the liquid in the water storage tank 4 is easily sprayed out through the flushing plate 8 to complete the cleaning effect of high-pressure flushing of the steel strip. The high-pressure water pump 81 is an existing product, and its principle is existing technology, so it will not be described in detail here.
[0023] Working principle: During the zinc scale removal operation on the steel strip, the steel strip is guided by the guide roller 7 and the pressure roller 61, so that the steel strip and the chemical solution in the soaking chamber 6 are in full contact to complete the zinc scale removal. After soaking, the steel strip enters the area below the rinsing plate 8, where the zinc scale is removed by the high-pressure water rinsing. The rinsing water is filtered by the filter plate 32 and discharged from the drain outlet 36. Under the action of the collection chamber 33, the filtered impurities can be collected, improving the overall performance and effect of the equipment.
