Description

Technical Field

[0001] The utility model relates to the technical field of steel strip cleaning, in particular to a steel strip surface grease cleaning device. Background Art

[0002] With the rapid development of industrial automation and manufacturing, steel products play a vital role in various fields, from construction, automobile manufacturing to precision machinery, aerospace, and household appliances. However, during the processing of steel, pollutants such as grease, lubricants, cutting fluids, and rust inhibitors often adhere to the surface. These residues seriously affect the subsequent treatment of steel such as welding, painting, heat treatment, and the quality and appearance of the coating. Therefore, efficient and environmentally friendly steel surface cleaning technology has become a key technical demand that the industry needs to solve urgently.

[0003] The existing steel strip cleaning process is: alkaline water spraying → alkaline water brushing → high-pressure clean water spraying → clean water brushing → clean water spraying. The alkaline water spraying process is arranged in a separate process tank, and its cleaning medium - alkaline water, is placed separately in another tank or container, which we call the alkaline water storage tank. During operation, the alkaline water is pumped into the spray pipe of the process tank through a water pump and a pipeline, and then the alkaline water is sprayed onto the upper and lower surfaces of the steel strip through the spray pipe, so that the grease on the surface of the steel strip undergoes saponification and emulsification reactions with the alkaline water; the alkaline water scrubbing process is arranged in the process tank, and the brush rollers used for scrubbing are arranged above and below the steel strip. The brush roller located above is called the upper brush roller, and the brush roller arranged below the steel strip is called the lower brush roller. During operation, the alkaline water is pumped into the spray pipe of the process tank through a water pump and a pipeline, and then the alkaline water is sprayed onto the upper and lower surfaces of the steel strip at the brush roller station through the spray pipe. The upper and lower brush rollers are driven by a motor to rotate on the upper and lower surfaces of the steel strip to perform the scrubbing process, and the grease that has undergone saponification and emulsification reactions is removed under the action of external forces. However, since the process tanks on the production line are difficult to seal, the cleaning medium may leak out of the process tank during operation, causing environmental pollution. Utility Model Content

[0016] Compared with the prior art, the utility model has achieved the following technical effects:

[0017] The process tanks on the existing production lines are difficult to seal well, which may cause the cleaning medium to leak out and cause environmental pollution during operation. In view of this shortcoming, the utility model designs a sub-tank and a main tank structure, in which the spray pipe and upper and lower brush rollers are arranged in the sub-tank, and a main tank is arranged outside the sub-tank. The cleaning medium that leaks out during operation is recovered by the main tank. The sub-tank is connected to the main tank, and the cleaning medium is stored in the main tank. During operation, the cleaning medium is pumped into the spray pipe by a water pump, and then the spray pipe sprays the cleaning medium onto the upper and lower surfaces of the steel belt, so that the cleaning medium will not splash out.

[0018] In the existing production process, the driving motor and adjustment motor of the lower brush roller are arranged at the bottom, and the cleaning medium splashes onto the motor for a long time, which will cause damage to the motor; the adjustment structure of the lower brush roller and its support roller is inconvenient to use. The utility model changes the adjustment structure of the lower brush roller and the lower brush roller support roller in the existing production process. In use, the lower brush roller and its lower brush roller support roller are both electrically adjusted, which is more convenient to adjust. The second brush roller driving motor and the second brush roller lifting adjustment motor of the lower brush roller are arranged above the sub-trough. When the steel strip is cleaned, it passes through the lower part of the sub-trough, and the splashed cleaning medium does not splash onto the motor, which solves this problem.

[0019] In the existing production process, the storage tank and the process tank of the cleaning medium are separated. During the process of transporting the cleaning medium from the storage tank to the process tank, the medium temperature will decrease due to the long pipeline. The medium with the lowered temperature needs to be replenished with heat in time to ensure the cleaning effect, which will cause energy waste. The utility model arranges the storage tank and the process tank together, with the mother tank as the storage tank and the child tank as the process tank. The transport pipeline is very short, so the cleaning medium has less temperature drop and the heating frequency is reduced, which successfully solves the problem of high energy consumption.

[0020] The existing production process cannot replace the lower brush roller during operation and needs to stop the machine for replacement. The utility model is designed with replacement holes on the sides of the sub-slot and the main slot. The lower brush roller can be replaced by opening the sealing cover of the replacement hole during the production process, which successfully solves this problem.

[0021] In the existing production process, a pair of squeeze rollers are arranged at the end of the process tank to squeeze out the residual cleaning medium on the surface of the steel strip. The surface of the squeeze roller is made of rubber material, which is easy to wear. After wear, the squeeze effect is poor and a new roller needs to be replaced. Since the lower squeeze roller is arranged below the steel strip, it cannot be replaced during the production process and needs to be replaced after stopping the machine. The replacement is cumbersome and delays production. The utility model adopts a water-blowing air knife at both ends of the mother tank to blow away the residual medium on the surface of the steel strip with air. There are no wearing parts, which avoids cumbersome operations and reduces production costs.

[0022] The equipment layout of the existing production process is complicated, occupies a large area, and the equipment integrity is poor. The utility model realizes a compact equipment layout, simple and practical, and easy operation. BRIEF DESCRIPTION OF THE DRAWINGS
