Meanwhile, after the lower ends of the vertical strips (4) are molten, the vertical strips (4) can automatically sink under the effect of gravity and impact vibration, and it is ensured that the bottoms of the vertical strips (4) make contact with the bottom plate (1) all the time. The slag filtering effect is stable, and reliability is high. The slag filtering device does not need to be frequently replaced, and the maintaining workload is small.

Movable aquatic product refrigeration box
ActiveCN108238344AQuality is not affectedQuality impactVariable capacity containersInternal fittingsThermal insulationAquatic product
The invention discloses a movable aquatic product refrigeration box. The movable aquatic product refrigeration box comprises a top cover, a clamping block, a buckle, a movable wheel, antiskid grooves,a box body, a pull rod, a lifting handle and a groove; the antiskid grooves integrated with the box body are uniformly distributed on the two outer side surfaces of the box body; the antiskid groovesare of rectangular structures; four and more antiskid grooves are distributed at equal intervals; and one side of the top of the box body is in hinged connection with the same side of the top cover.In the movable aquatic product refrigeration box, a thermal insulation plate with an adjustable height is positioned in the top cover of the refrigeration box; and through height adjustment of the thermal insulation plate, aquatic products occupy a corresponding volume of the relative box body, so that volatilization of ice blocks can be effectively reduced, the melting speed of the ice blocks isslowed down, long-time dipping of the aquatic products in water is prevented, and the quality of the aquatic products is not influenced.

Aluminum alloy fire-resistant window mounting structure
PendingCN108035670AHigh mechanical strengthEasy to installFireproof doorsFrame fasteningUltimate tensile strengthFire resistance
The invention relates to an aluminum alloy fire-resistant window mounting structure. The aluminum alloy fire-resistant window mounting structure is characterized in that steel beams are arranged inside side inner frames and a mullion inner frame, the inside and the outside of each steel beam are filled with fireproof poured materials, structural components are filled with fireproof poured materials, side outer frames and a mullion outer frame are filled with fireproof poured materials, and fastening strips are filled with fireproof poured materials. The aluminum alloy fire-resistant window mounting structure has the advantages that various inner frames, various outer frames, the various structural components and the various fastening strips are filled with the fireproof poured materials, fireproof materials are arranged at two ends of glass, the corresponding steel beams are arranged in the inner frames, and accordingly the mechanical strength of an aluminum alloy window can be improved; mounting components are divided into limit structures and load bearing structures, and accordingly the aluminum alloy fire-resistant window mounting structure is convenient to mount and detach andis the novel aluminum alloy fire-resistant window with the fire resistance of approximately 1 hour.
