Description

Technical Field

[0001] The utility model relates to the technical field of alkali mist absorption devices, in particular to an alkali mist absorption device for cold-rolled steel production. Background Art

[0002] Cold rolled steel is a steel plate produced by cold rolling, commonly known as cold plate. Cold rolling is to further thin the steel plate to the target thickness at room temperature. Compared with hot rolled steel plate, the thickness of cold rolled steel plate is more accurate, and the surface is smooth and beautiful. At the same time, it also has various superior mechanical properties, especially in terms of processing performance. Because the cold rolled original coil is relatively brittle and hard, it is not suitable for processing, so usually, it has to go through a series of surface treatments before it can be shipped out of the factory. In the process of producing cold rolled steel, in order to increase the corrosion resistance and durability of the steel plate, an anti-corrosion layer is set on the surface of the steel plate, such as galvanizing. Before this process, it needs to go through rust removal, pickling and other processes. In the rust removal process, alkali is usually used to remove rust, but alkali is easy to form alkali mist when it is heated. If the alkali mist is not collected and treated, the environment of the production workshop will be greatly affected, so it is necessary to propose an alkali mist absorption device.

[0003] According to an alkali mist absorption device for cold-rolled steel production disclosed in application number 202122441620.7, its structure includes an absorption box, and the absorption box is provided with a treatment tank, an air outlet pipe, a sealing cover plate and a driving motor. The treatment tank is located on the left side inside the absorption box, and the lower end of the air outlet pipe is sealed and connected to the upper end of the treatment tank, and the upper end of the air outlet pipe is located at the upper end outside the absorption box. The sealing cover plate is sealed and connected to the bottom of the absorption box, and the driving motor is fixedly connected to the left end of the absorption box. The output end of the driving motor is provided with a stirring rod. The utility model realizes the neutralization of alkali mist after absorption, avoiding the pollution of the environment again after the alkaline substances are discharged, and can also detect the pH value of the solution inside the treatment tank to prevent the operator from being unable to treat the waste liquid and products inside the treatment tank in the first time after the solution inside the treatment tank becomes alkaline.

[0004] However, the fog hood in the device has a single structure, and its position and absorption range are fixed. The alkali mist on the workbench will be deflected by different wind directions. The fog hood cannot absorb the deflected mist, which can easily cause a large amount of alkali mist to flow out and float into the production workshop, affecting the working environment.

[0005] In this regard, an alkali mist absorption device for cold-rolled steel production is proposed to solve the above technical problems. Utility Model Content

[0006] 1. Technical Problems Solved

[0029] Through the above structure, the alkali mist enters the air guide frame 8 through the mist absorbing hood 9, and the alkali mist is sent to the absorption box 1 for reaction treatment through the cooperation of the air guide hose 7, the air guide hard tube 6 and the air inlet pipe 3. Through the extension and retraction of the electric telescopic rod 12, the "convex"-shaped slider 13 slides inside the limiting slide groove 14, driving the air guide frame 8 and the mist absorbing hood 9 to adjust the angle. The specific structure is as follows:

[0030] Combined with Figure 1 and attached Figure 2 As shown, a sleeve 5 is provided between the air guide rigid tube 6 and the air intake pipe 3, the air guide hose 7 is a foldable bent tube, and a support rod 10 is rotatably installed on one side of the air guide frame 8 close to the mounting plate 11, and the other end of the support rod 10 is fixedly connected to the lower side of the air guide rigid tube 6.
