[0027] The high-pressure cleaning device provided in this embodiment has the spray seat 21 movably arranged on the mounting rail, and the operating side end of the spray seat 21 is locked and fixed on the operating side wall of the spray tank 1 through a quick release unit. After releasing the locking effect of the quick release unit on the spray seat 21, the quick release spray mechanism can be taken out of the spray tank 1 as a whole, realizing quick release and quick replacement, which can reduce the difficulty of maintenance and improve maintenance efficiency.

[0029] Preferably, an inspection window is provided on the operating side wall of the spray tank 1, which can be used as a disassembly and assembly channel for the quick-detachable spray mechanism. During normal production, the inspection window is blocked to prevent spray water from splashing out through the inspection window. When both the upper spray mechanism and the lower spray mechanism are quick-detachable spray mechanisms, the two can share one inspection window, or they can be independently configured with one inspection window each.

[0030] In one embodiment, if Figure 1 The quick release unit includes a plurality of quick clamps 11, the base of which is fixedly mounted on the spray tank 1, and the pressure head of the quick clamp 11 is pressed against the spray seat 21.

The quick-release unit is arranged on the outer wall surface of the operating side slot wall, which can ensure the convenience of operation.

[0034] A sealing gasket is preferably sandwiched between the flange plate 211 and the operating side groove wall to ensure the sealing of the inspection window.

[0035] Furthermore, the operating side end of the high-pressure water spray beam 22 is detachably connected to the flange plate 211, and the force and vibration generated by the high-pressure water spray beam 22 can be transmitted to the spray tank 1 via the flange plate 211, thereby improving the application reliability of the spray mechanism. The detachable connection method includes but is not limited to: a connecting flange is provided on the high-pressure water spray beam 22, and the connecting flange is detachably connected to the flange plate 211 through a plurality of bolts.

The hot air spray beam is used to spray high-temperature compressed air to dry the upper surface of the strip, which is convenient for subsequent processing of the strip. Among them, the hot air spray beam can adopt a straight pipe, whose axis is parallel to the width direction of the strip running channel, and the nozzle on the hot air spray beam sprays obliquely toward the incoming steel side; in particular, combined with the restraining effect of the V-shaped high-pressure water spray beam 22, a triangular area can be formed between the hot air spray beam and the upper high-pressure water spray beam, and the hot air has a certain residence effect in the triangular area, further improving the drying effect and efficiency.
