This invention proposes an energy storage container with an adjustment device, including a container body and a cooling cavity disposed within the container body, as well as an air-cooled cooling component, a liquid-cooled cooling component, a drying and impurity removal component, a gas conveying component, and an airflow adjustment component. By incorporating the component adjustment device, this invention effectively controls the airflow at the outlet by controlling the size of the outlet during the delivery of cold air. The outlet size is smaller closer to the air source, ensuring consistent airflow across all areas. Furthermore, the airflow can be adjusted according to the temperature differences in different areas, ensuring uniform cooling across all areas, preventing localized overheating, increasing battery life, and making the device more reliable.

This utility model discloses a cooling device for PVC film production, belonging to the field of PVC film processing technology. It includes a base and a conveying mechanism and a water-cooling mechanism installed inside the base. The air-cooling mechanism includes a conveying component and two blowing components disposed inside the base. The two blowing components are disposed opposite each other between the conveying component, and the blowing components are inclined towards the direction of film movement. An adjustment component is disposed inside each blowing component. By setting the air outlet of the blowing mechanism towards the direction of film movement, cold air is blown out at a tangential angle "attached" to the film, without directly impacting the film surface. This effectively cools the film surface while reducing disturbance to the film material surface, thereby reducing film vibration during heat dissipation, decreasing the probability of film wrinkling, and minimizing the impact on the uniformity of the finished product.

The invention relates to the technical field of agricultural machinery, and discloses a pneumatic seedling vine impurity removal device based on a potato combine harvester, which comprises a rack, a fan body, a fan transmission mechanism, a transverse conveying chain sieve and a seedling picking chain sieve, and the transverse conveying chain screen comprises side pattern discharging teeth rotationally installed on the inner side of the rack, side discharging chains are installed on the surfaces of the side pattern discharging teeth, non-blocking rubber coating is fixedly installed on the inner sides of the side discharging chains, and an air duct lower protection plate is fixedly installed on one side of the interior of the rack. According to the pneumatic seedling vine impurity removal device based on the potato combine harvester, residual seedlings and weeds in potato tubers are effectively separated through airflow generated by the fan body, the structural design enables the residual seedlings and the weeds to be accurately separated according to the length and weight difference of the residual seedlings and the weeds, and therefore the impurity removal efficiency is improved; and the cleanliness of the potato blocks is ensured.
