3results about How to "Improve fumigation efficiency" patented technology

The utility model relates to the technical field of grain storage discloses a kind of inner ring flow fumigation equipment for granary, including base, the top of base is fixedly connected with installation platform, the top of installation platform is fixedly connected with driving motor, the top of base is fixedly connected with shell, the inside rotation of shell is connected with fan, the output of driving motor is fixedly connected with driving shaft, the side of driving shaft away from driving motor is fixedly connected in the inside of fan, the side of shell away from driving motor is fixedly connected with air inlet, the top of shell is fixedly connected with air outlet.The dustproof mechanism includes dustproof filter plate, and the dustproof filter plate is slidably connected inside the air inlet.In the utility model, the dustproof filter plate inside the air inlet can effectively prevent solid particles from being drawn into the shell, which affects the operation of the fan, ensures the operation efficiency of the fan, improves the fumigation effect of the grain and ensures the safety of the working environment.

The utility model discloses a steam softening device for the putty ground paper wall painting disease, relate to the cultural relic restoration technical field. Including steam engine, steam spray gun, sealed adapter and end air outlet spare. Through setting up various end air outlet spare, can be aimed at paper wall painting different layer structure and carry out pertinence steam fumigation softening. The silica gel softening cover can effectively seal the steam in the repair area, and make the repair area keep a certain time's local high humidity state, the steam enters the silica gel softening cover and will not immediately dissipate, improves the fumigation efficiency, is favorable to the softening crack, and the deformation ground layer of lifting and warping, the multi -way steam spray pipe can fumigate ground layer from multiple directions, realizes the whole piece softening of ground layer, the one -way steam spray pipe can fixed point pertinence fumigation ground layer, and the fumigation efficiency is improved greatly, and the softening repair effect is improved.

The present application relates to a kind of finished grain stacking system, including stacking group, each stacking group includes at least two stacking series, each stacking series includes at least two stacking components, stacking component includes the stacking cage with the cage fork hole being provided at bottom, stacking cage includes cage bottom plate and the three lateral cage side limit being arranged on the upper end of cage bottom plate, define the two stacking cages adjacent in upper and lower direction in the same stacking component as upper side stacking cage and lower side stacking cage, the bottom four corners of upper side stacking cage are connected with the top four corners of lower side stacking cage by the positioning structure of concave-convex positioning cooperation along the upper and lower direction, stacking component further includes the tray for being placed on the upper side of cage bottom plate, tray bottom is provided with tray fork hole, and finished bagged grain is stacked between the upper side of tray and each cage side limit, the present application solves the technical problem that the lowermost packaging bag is easily damaged under greater pressure in the prior art, and the stacking structure is unstable and easily inclined to collapse.
