摘要： PROBLEM TO BE SOLVED: To efficiently purify exhaust gas with a small and inexpensive device by providing a gas-liquid separating chamber on a water tank of a large capacity, injecting special additive water in the water tank into the gas-liquid separating chamber in fine spays, and bringing th water into contact contact with the exhaust gas to aggregate black smoke particles. SOLUTION: When special addition water is stored in a water tank 1 and a suction blower 7 and a circulation pump 13 are driven, the special additive water supplied to plural spray nozzles 12 provided around the upper part of the side wall of a gas-liquid separating chamber 4 is ejected to the upper part of the out side space 6 of a cartridge filter 5 in fine sprays. At this time, simultaneously, diesel exhaust gases 34, 34' are sucked together with outside airs 17, 17' into suction nozzles 10, 11 through ducts connected with each exhaust opening of a pump vehicle and a mixer vehicle for center construction. The gases are rapidly cooled in contact with the special additive water sprays during its long circulation in the upper part of the outer side space 6, black smoke particles are aggregated and then trapped with the filter 5, and the purified gases are discharged from the exhaust openings 36.

摘要： PROBLEM TO BE SOLVED: To provide a dust discharge method enabling to dissolve clogging of a filter without being instantaneously affected to a filter chamber of a dust collector. SOLUTION: This device is attached a bellows valve 13 molded from a soft sheet to a dust discharge port 11 of the lower part chute 12 provided on the dust collector 1, and pulse waves are intermittently exerted on the upper part of the dust discharge port 11 from the filter 2b by an air pulse valve 8 installed on the filter 2 set in a filter chamber 3 of the dust collector 1 in such a state that the bellows valve 3 was closed by the internal pressure caused by suction for dust collection, and then the dust deposited on the lower part chute 12 is compacted and the dust is automatically discharged by pushing the bellows valve 13 open with gravity of the powder and also powder pressure at a time of compacting.

摘要： PROBLEM TO BE SOLVED: To remove a large quantity of cutting dust caused when a tunnel free cross section is digged without diffusing the dust into the air. SOLUTION: A cutting drum or a chisel provided at a tip of a boom of a tunnel free cross section excavator is wrapped up by a hood 9 following it in accordance with a cutting depth, foaming agent solution for digging rock is foamed, and a large quantity of foaming bodies are poured into the hood 9 so that cutting dust covered with the foaming bodies is fed under pressure according to the order of a vacuum hose 14, a cyclone 15 rough dust separation, a fan 16, a silencer 18, a wind pipe, and a dust collection machine 17 from the hood 9 to remove the dust.

摘要： PROBLEM TO BE SOLVED: To provide a link feeder with a wide variety of applications. SOLUTION: A charging chute 1, a discharge chute 3 and a driving unit case 4 are connected to each other with a pipe 5, an endless wire 21 is penetrated into a through hole provided at a position with an equal distance in three directions from the center of a large number of plates 17 having a diameter approximating the inner diameter of the pipe 5, and each soft sleeve spacer through which the endless wire 21 is penetrated is interposed between each of the plates 17. Between one end of each of these spacers and each of the plates 17, each sleeve fixed to the endless wire 21 is interposed, pairs of sprockets around which chains with claws 28A and 28B abutting both ends of each of the plates 17 are wrapped are supported at both ends of a moving zone of each of the plates 17 in the driving unit case 4, and to the driving sprockets in these sprockets, driving units for synchronously driving them are connected.
