3results about How to "Reduce work pressure" patented technology

This invention provides a powder tanker unloading system, including a temporary storage tank. The upper part of the temporary storage tank is connected to a feed hose, and the upper end of the temporary storage tank is connected to a filter shell. The filter shell has an exhaust port connected outwards, and a dust filter element is installed inside the filter shell. The lower end of the temporary storage tank is connected downwards to a discharge pipe. A unloading section is located at the lower end of the powder tanker. A discharge pipe, detachably connected to the free end of the feed hose, is located at the bottom of the unloading section. An air injection pipe is arranged around the unloading section. The discharge pipe has a strip-shaped feed inlet extending along its length within the unloading section. Multiple high-pressure air blowing pipes, extending into the unloading section and facing the strip-shaped feed inlet, are arranged inwards from the air injection pipe. The free end of each high-pressure air blowing pipe is open and inclined towards the sealing plug. This invention utilizes high-speed airflow to propel the powder quickly unloading, eliminating the need to maintain a high-pressure environment inside the tank, resulting in lower unloading energy consumption and greater safety.

This utility model belongs to the field of interventional medical devices, specifically relating to a medical endoscope catheter, comprising: a tubular body, wherein an airflow channel extending axially along the inner wall of the tubular body is provided; an end wall, disposed at the first end of the tubular body, wherein a through hole is provided through the end wall, and a plurality of circumferentially spaced ribs are provided on the side of the end wall facing the inner cavity of the tubular body, wherein each rib is distributed in a vortex shape. The airflow is continuously guided by the arched ribs to form a stable vortex ring, reducing energy dissipation caused by turbulence and improving airflow utilization under the same air source pressure; this utility model transforms disordered flow into controlled vortices through geometric constraints on the airflow path, improving cleaning efficiency while reducing the system's working air pressure.

The utility model discloses a silkworm rearing table, a silkworm rearing frame and a silkworm rearing system. The silkworm rearing table comprises a frame body and a T-shaped plate arranged in the frame body in a sliding and penetrating mode. The T-shaped plate comprises a vertical plate and a bottom plate; the vertical plate is connected with the bottom plate; the bottom plate is of a folding structure; a pull rod penetrates through the vertical plate in a sliding manner; a scraping plate is arranged at one end, positioned in the frame body, of the pull rod; a net-shaped interlayer is arranged in the frame body; the net-shaped interlayer is positioned above the T-shaped plate; and a handle is arranged on the T-shaped plate. In practical application, the silkworm tables are vertically arranged on a silkworm frame for silkworm breeding, the space utilization rate of a silkworm rearing room can be improved, when the temperature of the silkworm rearing room is too low, the folded T-shaped plates in the frame body are pulled out, unfolded and hung on the periphery of the silkworm frame, windproof heat preservation can be conducted on the silkworm tables, and the breeding environment is effectively guaranteed; the influence of over-low temperature on the immunity and food intake of silkworms is prevented.
