Abstract

The invention discloses a water spraying and dust removing device. The water spraying and dust removing device comprises an upper water spraying device and a lower water spraying device. The water spraying and dust removing device is characterized in that the upper water spraying device is arranged above an upper outlet guide plate and comprises a steel plate, an upper spray nozzle, an upper water collection tube and an upper taper connector; the lower water spraying device is arranged below a lower outlet guide plate and comprises a lower spray nozzle, a lower water collection tube, a lower taper connector and a tube clamp. The water spraying and dust removing device effectively solves the problem that the temperature of strip steel is influenced due to the fact that the spray nozzles and the guide plates are not sealed to cause cooling water to leak onto the strip steel, so the production quality of the strip steel is improved.

Description

technical field [0001] The invention belongs to the technical field of steel rolling, and in particular relates to a water spray dedusting device. Background technique [0002] A large amount of smoke and dust will be generated during the production of hot-rolled strip steel, which will pollute the surrounding environment, endanger the health of the staff, and threaten the motor, reducer, and large instruments and affect production. In response to this problem, in China earlier, methods such as pipeline suction and water curtain dust removal were used for dust removal, but the investment cost was relatively high. At present, the combination of pipeline suction dust removal and water spray dust removal is generally used, but the existing water spray dust removal device causes water leakage after the protective cover is corroded by the cooling water of the roll, and the nozzle and the guide plate are not sealed, making these The water leaks onto the strip through the hole whe...
