The main spray frame is positioned at the outlet and inlet of the pickling tank, and the main spray beam at the outlet and inlet is inserted into the main spray frame to protect the main spray beam from being impacted and rubbed by strip steel and avoid the damage of the main spray beam. The existing main spraying frame consists of a protection pipe, a protection frame, an end plate and a plastic lining steel pipe, and a rib plate has the defects that the bottom is weak, the main spraying frame is easy to damage due to long-time impact and friction of a steel belt, and the thermal deformation is large. The specific expression is as follows:
1. the thermal deformation is large: the bottom of the existing main spraying frame is only provided with a layer of plastic plate, the upper part of the existing main spraying frame is provided with a layer of plastic plate, a plastic lining steel pipe and a rib plate are arranged above the plastic plate, the heat deformation resistance is uneven after the existing main spraying frame is heated, and the middle protection pipe can deform.
2. Is easy to damage by being impacted and rubbed by the strip steel: the bottom of the existing main spraying frame is only provided with a layer of plastic plate, and is easy to damage due to long-time impact and friction of strip steel.
Disclosure of Invention
The utility model aims at solving the problems of the main spray frame in the prior art, and provides a main spray frame which is crashproof, friction-resistant and small in thermal deformation, so that the problem that the main spray beam cannot be pulled out due to the fact that the main spray frame is damaged due to the impact and friction of a steel plate and the thermal deformation is effectively solved.
The aim of the utility model is realized by the following technical scheme:
the main spraying frame is characterized by comprising a protection frame composed of an upper protection plate, a lower protection plate and a side protection plate, a protection pipe arranged in the protection frame, a plastic lining steel pipe welded on the upper part of the upper protection plate, an upper rib plate, a plastic square rod welded on the lower part of the lower protection plate and a lower rib plate, and acid discharge holes respectively arranged on the upper protection plate, the lower protection plate and the side protection plate.
End plates are welded on two sides of the protection frame.
The upper protection plate, the lower protection plate and the side protection plates of the protection frame are PPS plastic plates.
The protection pipe is a PPS pipeline.
The outside of the plastic lining steel pipe is made of PPS material, the inside of the plastic lining steel pipe is of a square steel pipe structure, and PPS plugs are welded at two ends of the plastic lining steel pipe.
The utility model has the advantages that:
(1) The main spray frame has small thermal deformation, and the bottom is reinforced against the existing main spray frame, so that the thermal deformation of the main spray frame is controlled, and the main spray beam can be smoothly pulled out;
(2) The main spraying frame is impact-resistant and friction-resistant, and the plastic square bars and the rib plates are welded at the bottom of the main spraying frame, so that the service life of the main spraying frame is prolonged.
