This utility model relates to the technical field of filter element processing equipment, and in particular to a filter element meltblown material collection and forming machine. It includes a screw extruder, with nozzles for spraying melt installed at the discharge end of the screw extruder. Each nozzle has a spray hole and upper and lower air holes respectively located above and below the spray hole. The material collection mechanism includes a base plate and a first mounting base mounted on the base plate. A transversely arranged material collection rod is rotatably mounted on the first mounting base. A second mounting base is also mounted, with a rotating rod rotatably mounted on the second mounting base, coaxially with the material collection rod. A threaded rod is located on the outer side of the rotating rod and coaxially with it, passing through the interior of the material collection rod. The rotation speed of the rotating rod is greater than that of the material collection rod. By setting the threaded rod and creating a speed difference between the threaded rod and the material collection rod, the filter element automatically moves laterally during the automatic rotation and forming process, resulting in a consistent filter element thickness and improving the forming efficiency and quality of the filter element.

The utility model provides a quick replacement device for a bushing brick of a basalt fiber smelting furnace, and belongs to the technical field of fiber processing. The quick replacement device for the bushing brick of the basalt fiber smelting furnace comprises a fence body and a first electrical bar. The fence body makes contact with the bushing in an attached mode under the dead weight of the fence body, and the bushing brick is surrounded in the fence body. A plurality of first mounting blind holes are formed in a circle in the perimeter direction of the fence body. And the first electric heating rods are arranged in the first mounting blind holes one by one. According to the utility model, a smelting furnace does not need to be stopped, heat can be continuously provided for residual melt in the liquid tank in the use process, the melt is prevented from being cooled and solidified, and great convenience is provided for replacement of bushing bricks; meanwhile, the space between the outer side of the fence body and the liquid tank can serve as a temporary storage space for melt discharged by the smelting furnace body, the risk caused by the fact that the smelting furnace body does not discharge materials for a long time is avoided, the smelting furnace body does not need to be powered off in the bushing brick replacement process, and energy consumption generated when the smelting furnace body is started again after cooling is saved.

The utility model relates to road construction technical field discloses asphalt spraying device, including mobile platform, the right side of mobile platform is provided with spraying mechanism, the top left side of mobile platform is provided with constant temperature mechanism, the outer wall all around of mobile platform is rotatably connected with mobile wheel, the top right side of mobile platform is provided with lifting assembly, the left side fixed connection of mobile platform has the push column, the top front side of mobile platform is provided with suction assembly, the spraying mechanism includes U-shaped board piece, the left side sliding connection of U-shaped board piece in the right side of mobile platform, in the utility model, through the rotation of linkage gear, make the same rotation of triangular arc cylinder in fixed cylinder 202, scrape fixed cylinder under the high -speed rotation of triangular arc cylinder, prevent the impurity from entering the spraying nozzle, and the impurity is pushed to the collection component by shaftless screw auger, thereby avoid the blockage of nozzle, lead to uneven spraying.
