摘要： PROBLEM TO BE SOLVED: To lower a surface temperature of a heat insulating panel, and shorten a periodic inspection period by filling a heat insulating material inside a box body, arranging a hollow flat refrigerant passage member to cover a great part of its plate in a part close to the box face plate side where the box body is turned to a heat insulating part, and forcedly flowing air in the passage member. SOLUTION: A box-type heat insulating panel is used in a part opposit to a heat source part D. When the heat source part D is operated, an opening part 2a from which a refrigerant blowing-off box-shaped nozzle member C1 is pulled out and an outlet of a passage part 4, are closed by a heat insulating material. For example, when the heat insulating panel is removed at periodic inspection time, the closing heat insulating material is removed, and the box-shaped nozzle member C1 is fitted and inserted, and air is flowed in a hollow flat passage member C from an air blower. Conduction heat to the heat insulating panel from the heat source part D is taken in inflow air by the inflow, and is released outside, and a surface temperature of the panel is lowered, and at the same time, a temperature drop in the heat source part 4 itself is also promoted. A temperature can be lowered in a short time, and a periodic inspection period can be shortened from the improvement of a burn preventive work environment or the like at removing work work time and shortening of inspection time.

摘要： PROBLEM TO BE SOLVED: To provide a method for efficiently separating suspended substances in the waste liquid of a shochu (Japanese distilled white liquor). SOLUTION: This method for separating suspended substances in the waste liquid of a shochu comprises using as an endless conveyer A felt having a fabric density (metsuke unit, 4.356g/m ) of 1500-4000g/m and made by needling a dense fiber pad having smooth surfaces on a coarse cloth as a core, supplying a shochu waste liquid onto the conveyor from a hopper to impregnate the felt with the liquid component, scraping off the solid component left on the conveyer with a scraper 6, and subsequently squeezing out the liquid component impregnated into the felt with a pair of press rollers 7 to recover the liquid component.

摘要： PROBLEM TO BE SOLVED: To effectively remove foreign matters such as sand entering between fibers of waste material heat-insulation rock fiber. SOLUTION: A container 3 for waste, whose bottom is a grid 3a, is arranged so that it can swing up and down and supported by means of a spring 8, and an arm 16 having rollers 15, 15 at its both ends is fixed onto a shaft 12 driven by a motor 9. When the arm 16 is turned, the roller 15 pressing down the container 3 against the force of spring 8, and thereafter the container 3 is released so that it is swung suddenly upward by the accumulated repelling force of the spring 8. Then, waste in the container 3 is striken against a cover plate of the container 3 strongly, whereby forign matters entering between the fibers of water are discharged and taken out through the grid 3a. Accordingly it is possible to effectively remove forign matter from waste of insulation material made of rock fiber in a block form with a different shape and size.

摘要： PROBLEM TO BE SOLVED: To provide a metal reflection type heat in sulfating device which has an excellent manufacture processability, and can exhibit the insulating property at the maximum. SOLUTION: In a metal reflection type heat insulating device composed by filling and a arranging numerous metal sheets 2 in the laminating form inside a semicylindrical metallic case surrounding a piping P, V-shape ribs 2a and 2b embossed in the grill form to the metal sheets 2; and conical projections 2c existing at the grill surface parts partitioned by both ribs, and embossed higher than the ribs 2a and 2b; are provided. As a result, the strength of the metal sheets themselves can be improved by the ribs 2a and 2b provided in the grid form, the clearances between metal sheets are maintained constant as the whole, by the functions of the grid form of ribs and projections which are bent in a polygonal form making the metal sheets concentric to the cylindrical case regularly, and air layers (fixed intervals) effective to the insulating effect can be maintained. Furthermore, in the structure making the projections in concal projections, the heat conduction by the contact of metal sheets each other can be made in a small amount which can be ignored.

摘要： PROBLEM TO BE SOLVED: To simultaneously perform separation treatment by difference in specific gravity and by screening by providing a vessel which houses plastic balls having specific gravity between that of materials of low specific gravity and those of high specific gravity in objects to be separated in layers and whose bottom part is formed into meshes and vibrating the vessel by a vibrator. SOLUTION: When separating waste calcium silicate heat insulators, crushed materials are fed to the shallow layers side of plastic ball layers and a vessel 1 is vibrated in the longitudinal direction. Then by difference in specific gravity between the plastic balls having a density between those of materials of low specific gravity and of high specific gravity in objects to be separated and the objects to be separated, calcium silicate lumpy materials to be reused remain on plastic ball layers. On the other hand, metal pieces or stones, wire scrap, chips of wood and the like sink in the ball layers and reach bottom meshes 2 and are separated. At the same time, calcium silicate pieces and granular materials pass through spaces between the balls 3 and sink and further are screened by the meshes 2 and recovered under the vessel 1.
