This utility model discloses a melting and casting device for recycling Babbitt alloy from a pear-shaped steel wire rope sheath. It includes a housing, a medium-frequency induction furnace housed within the housing, and a casting mold. The medium-frequency induction furnace comprises a furnace body, a capacitor box, and a power supply box. The furnace body has a hollow structure extending vertically, with a lifting port at the top and an open bottom. The furnace body is designed with three layers from the outside in: an outer layer of heat insulation plate, a middle layer of induction coils arranged in a spiral pattern using hollow copper tubes, and an inner layer of fireproofing mud. The power supply box is electrically connected to the capacitor box and the induction coils. The casting mold is located below the furnace body. Eddy currents are generated inside the pear-shaped steel wire rope sheath suspended in the furnace by the induction coils, generating heat to heat the sheath. When the heating temperature exceeds 230°C, the Babbitt alloy inside the sheath melts rapidly, forming a flowing liquid that drips directly into the casting mold below. Finally, it cools and is demolded, achieving effective recycling of the alloy.

This invention discloses a laser cutting device for CNC machining equipment, relating to the field of CNC laser cutting technology. It includes a cutting device body, comprising a laser cutting head; and a processing mechanism mounted on the cutting device body, comprising: a cooling shroud fixed to the cutting device body and fitted onto the laser cutting head, the cooling shroud having vents arranged in a circumferential array; and an air shroud fixedly fitted onto the cooling shroud. This invention uses a linkage between a cooling component and a fume extraction component. High-temperature flue gas is pre-cooled by the cooling shroud before filtration, preventing damage to soft pipes from high temperatures and extending the lifespan of the pipes and fume extraction components. Metal particles in the flue gas are collected by a collection frame and filter. After shutdown, a switching component automatically switches the pipes, using the airflow from the fume extraction component to blow residual coolant in the cooling shroud back to the liquid tank, completely preventing pipe scaling and blockage, and maintaining long-term stable heat exchange efficiency of the cooling system.

The utility model discloses a carbon black muffle furnace with safety protection function, including muffle furnace body, the inside of muffle furnace body is provided with heating cavity, the lateral wall of heating cavity is provided with the chute, the inner wall sliding connection of chute has the movable block, one end fixed connection of movable block has the placing plate, and another end of movable block installs the mobile mechanism with placing plate cooperation. In the utility model, through setting the placing plate, chute and mobile mechanism, through the rotation handle, the movement of connecting block can be driven through screw rod, drives the unfolding or folding of scissor fork frame to move placing plate and movable block along the chute, can move out the inside of muffle furnace body outward, convenient to use, save time and effort, also can avoid the operator from inside and take the material, and the scalding accident occurs, and the operation is more safe, simultaneously, when along with the chute and move the crucible that is equipped with carbon black, can keep stable, guaranteeed the stability when the crucible moved out.

The utility model provides an exhaust tail throat, a noise elimination structure and a vehicle, and belongs to the technical field of vehicle exhaust systems.The exhaust tail throat is provided with a color changing ring, when the temperature of a tail throat body rises to a high-temperature state, the color changing ring is changed into striking red or orange from light color, high-temperature warning is achieved, and scalding caused by mistaken touch is effectively prevented; the containing cavity is formed in the tail throat body, the exposed notch is formed in the rear end of the containing cavity, the color-changing ring is embedded in the tail throat body, the stable display function of the color-changing ring is ensured, the effect of protecting the color-changing ring is achieved, stability and durability are improved, the color change of the color-changing ring is compared with the metal texture of the tail throat body, and the color-changing effect of the color-changing ring is improved. The exhaust tail throat is endowed with science and technology sense and layering sense, and the appearance coordination of the whole automobile is improved. By arranging the elastic pushing piece, continuous backward elastic pushing force is formed on the color-changing ring, so that the color-changing ring tightly abuts against the cavity rear wall all the time, and it is ensured that the position of the color-changing ring is stable.
