The utility model relates to a shading glue coating device which comprises a box body, an extrusion roller and a coating roller are arranged in the box body, rotating shafts I which extend to the outer side of the box body and are driven by a motor are arranged at the two ends of the coating roller, gears I are arranged on the rotating shafts I on the outer side of the box body, and inner gear rings arranged on the gears I in a sleeving mode are arranged on one side of the box body. Gears II are arranged on the two sides of the inner bottom of the opening of the inner gear ring, a driving rod connected with the gears II is arranged in the box body, and a stirring paddle is arranged on the driving rod; the extrusion roller comprises a cylinder, rotating shafts II are arranged at the two ends of the cylinder, a protruding base for fixing one group of rotating shafts II is arranged at the top of the box body, a gear III meshed with the gear I is arranged at the tail end of the rotating shaft II on the outer side of the protruding base, a positioning plate is sleeved outside the tail end of the cylinder on the same side as the protruding base, and a cylinder is sleeved outside the cylinder on the outer side of the positioning plate. And an annular seat for locking and fixing the cylinder on the cylinder is screwed on the other group of rotating shafts II. The device is simple in structure and convenient to use.

The application relates to a heat exchange device, an ethylene heating method and an ethylene storage system. The heat exchange device comprises a heat exchange medium storage space, a first heat exchange pipeline and a second heat exchange pipeline. The heat exchange medium storage space stores heat exchange medium. The melting point of the heat exchange medium is not higher than -90 DEG C, and the boiling point is not higher than 80 DEG C. The pipe body of the first heat exchange pipeline is arranged in the heat exchange medium storage space, and the pipe opening of the first heat exchange pipeline is arranged outside the heat exchange medium storage space. The first heat exchange pipeline is used for passing in steam to heat the heat exchange medium. The pipe body of the second heat exchange pipeline is arranged in the heat exchange medium storage space, and the pipe opening of the second heat exchange pipeline is arranged outside the heat exchange medium storage space. In the direction of gravity, the second heat exchange pipeline is arranged above the first heat exchange pipeline. The application indirectly exchanges heat between ethylene and steam through the heat exchange medium, and the risk of leakage is not easy to occur.

This utility model discloses a line marking and positioning machine for landscaping construction projects, including a positioning machine base, a ground sweeping mechanism, an adjustable line marking mechanism, a material tank heating mechanism, and a lifting mechanism. The ground sweeping mechanism includes a motor and a roller brush installed at the upper and lower ends of the lifting mechanism. The adjustable line marking mechanism includes a material box fixed at the center of the bottom of the positioning machine base, with multiple nozzles evenly spaced at the bottom of the material tank's inner wall. This utility model removes dust and gravel from the road surface during the line marking process using the roller brush at the upper end of the ground sweeping mechanism, eliminating the need for water washing and thus preventing oil dilution. The line thickness can be adjusted by adjusting the distance of the cover plate on the material box, eliminating the need for multiple nozzles and reducing line marking costs. The heating plate heats the oil in the material tank, preventing it from solidifying and melting it even when it does solidify, without affecting later use or cleaning of the oil tank.
