This utility model provides a wool opening device, belonging to the field of wool processing technology. It includes a material box containing an opening mechanism for processing wool. The opening mechanism includes a feeding component and an opening component. The feeding component feeds wool into the material box, and the opening component is located below it, used to open the wool fibers. The feeding component includes a feeding ramp symmetrically mounted on the top of the material box and a feeding shaft symmetrically mounted above the ramp. Several feeding guide rods are distributed on the feeding shaft. This utility model can shred wool using meshing crushing rollers, avoiding problems such as uneven stress on wool fibers during opening due to improper or inaccurate roller coordination, and potential damage to some wool fibers due to over-opening.

The application belongs to the technical field of oil and gas exploitation, and particularly relates to a high-emulsification sewage treatment device for oil and gas fields. The high-emulsification sewage treatment device for oil and gas fields comprises an electric flocculation cabin and a cyclone cabin, a cyclone pipe is arranged on the electric flocculation cabin, sewage enters the electric flocculation cabin through the cyclone pipe, an outer ring electrode, an inner ring electrode and a center ring electrode are sequentially and fixedly arranged in the electric flocculation cabin in a spaced coaxial manner from outside to inside, the polarity of the outer ring electrode and the center ring electrode is opposite to the polarity of the inner ring electrode, after the sewage enters the electric flocculation cabin, the sewage first passes through the annular space between the outer ring electrode and the inner ring electrode, and then passes through the annular space between the inner ring electrode and the center ring electrode. The application can efficiently separate impurities in the sewage, and occupies a small space.

The utility model provides an aluminum bar furnace, which relates to the technical field of aluminum bar heating equipment and comprises a furnace body and a heat exchange purification device. The heat exchange purification device is connected and communicated with the exhaust port, the heat exchange purification device comprises a heat exchange structure, a filtering structure and an exhaust hopper, one end of the heat exchange structure is connected and communicated with the exhaust port, and the end, away from the exhaust port, of the heat exchange structure is connected and communicated with the filtering structure; and one end, far away from the heat exchange structure, of the filtering structure is connected and communicated with the exhaust hopper. According to the aluminum bar furnace, high-temperature mixed gas generated by the aluminum bar furnace can be effectively purified, the air quality is guaranteed, and the aluminum bar furnace has important significance for achieving sustainable development, reducing energy consumption and protecting the environment.

A vehicle-mounted display screen and a using method thereof relate to the technical field of displayers, the vehicle-mounted display screen comprises an outer frame and a display screen, the display screen is mounted in the outer frame, the front of the outer frame is open, supporting rods are mounted on two sides of the display screen, a closed rotating plate is mounted on the upper side, corresponding to the display screen, of the outer frame, and the closed rotating plate is horizontally arranged above the display screen. Connecting rods are fixedly connected to the middles of the two sides of the closed rotating plates, the connecting rods are perpendicular to the closed rotating plates, driving blocks are arranged at the bottom ends of the connecting rods, the driving blocks are circular, fixing shaft pins are arranged in the middles of the driving blocks, the racks are meshed with gear teeth on the driving blocks, and the two sets of closed rotating plates which are symmetrical up and down are arranged in the outer frame. The racks are symmetrically arranged on the upper side and the lower side of the extension rod, so that when the front portion of the automobile is impacted, the closed rotating plate can rotate around a fixed shaft pin of the driving block and then move to the front face of the display screen from the upper side and the lower side of the display screen, the front face of the display screen is protected, and splashing fragments generated when objects in the automobile impact the display screen are avoided.

This utility model discloses a mobile support structure for a backpack water cannon used in forest fire fighting, including a water tank, an aerosol sprayer, an air cylinder, and a support frame. Support rods are used to fix the water tank. The support frame includes side panels symmetrically arranged on the surface of the water tank, a first support rod at the front of the side panels, and a second support rod at the rear of the side panels. A fixing rod is installed at the bottom of the second support rod, and a rotating shaft is installed at the bottom of the fixing rod. Locking mechanisms are provided at both ends of the rotating shaft to limit its movement. By incorporating the fixing rod, rotating shaft, and telescopic rod, this utility model allows for a higher support structure at the bottom of the entire device, conforming to the user's height. This provides ground-level support for the user on flat surfaces, when standing for extended periods, and when the water tank is full during firefighting, reducing the user's continuous physical exertion due to the weight of the entire device.
