Abstract:
Pneumohydraulic dying machine including a cylindrical body (10) and a pneumohydraulic dying unit (20). A cloth (3) to be dyed is circularly driven in the cylindrical body (10). The pneumohydraulic dying unit (20) includes a blower (23) for blowing a great amount of air to atomize and mix with liquid dye. A rectangular straight nozzle (13) sprays the mixture of air and liquid dye onto the circulated cloth (3). The air and the liquid dye are independently input from upper and lower sides into the nozzle (13) by independent bypasses (241,242,226,227) and conduits (25). The amount of upper and lower sprayed air and the liquid dye can be independently controlled and adjusted in accordance with the property of the cloth. A washing/cleaning tube (26) is further disposed in the cylindrical body in front of the nozzle (13) for washing off the dye and remainders remaining on the cloth (3).
Abstract:
A gas-liquid dye-spraying apparatus (20) including at least one set of siphon-type nozzles (22,23) disposed on each of the upper and lower sides of the spraying passage (200) in the dyeing machine. The nozzles (22,23) eject strong wind to stably siphon the dye. The dye is more evenly atomized and distributed so as to achieve better evenness of dyeing. The wind pressure and the mixing ratio of the air to the dye can be independently and mobilely regulated. Therefore, the cloth (70) can be better guided and circulated. Also, the consumption of the dye is reduced.
Abstract:
A heat exchanging apparatus for increasing/decreasing dye temperature of a gas-liquid dyeing machine, including a heat exchanger (10) installed between the inlet (31) and outlet (32) of the dye-circulating pipe (30) of the dyeing machine (20). At least one partitioning layer (11) is disposed in an interior of the heat exchanger (10) to partition the interior into a gas flowing space (13) and a dye flowing space (12). The dye flowing space (12) has a dye inlet (121) and a dye outlet (122) which are respectively connected to the dye outlet (32) and dye inlet (31) of the dyeing machine (20). The gas flowing space (13) has a gas inlet (131) and a gas outlet (132). The gas inlet (131) is connected to a cold air source (40) and a steam source (50). The gas outlet (132) is connected to a water condenser (60). Multiple tubular vacuum thermally conductive elements (14) are inserted on the partitioning layer (11). Each thermally conductive element (14) has two ends which respectively extend into the gas flowing space (13) and the dye flowing space (12). By means of the high efficiency heat exchange of the vacuum thermally conductive elements (14), the temperature of the circulated dye can be quickly increased/decreased and more stably controlled.

Abstract:
Pneumohydraulic liquid dye-spraying apparatus including a rectangular straight nozzle (13) and an upper and a lower sector-shaped air input conduits (25). The nozzle (13) is composed of upper and lower sets of guide boards (1311,1321) having opposite oblique guide edges each defining an elongated straight spray jet (131,132). Each spray jet (131,132) is independently provided with an air input conduit (25). One end of the conduit (25) is formed as an inlet (251) which is diverged and extended toward the other end of the conduit to form a sector-shaped outlet (252) for connecting with the nozzle (13). An atomizing nozzle (253,254) is mounted on the conduit (25). During spraying operation, the liquid dye passing through the nozzle (13) is evenly atomized and sprayed onto a dyed piece (3). The amount of upper and lower sprayed air and the liquid dye can be independently controlled to meet requirements of different dyed pieces.

Abstract:
An improved cover assembling structure of a key ring, the key ring has a main body being provided respectively on an upper and a lower surface thereof with recesses that are provided at middle peripheral sections of the lateral sides of the main body with notches, at least an insertion hole is provided at each middle section of the recesses of the upper and lower surfaces. The upper and lower covers have contours in coincidence with those of the recesses, and have lateral wing pieces for inserting into the notches. Thereby, the upper and lower covers can be inserted into the recesses; insertion stubs provided on the upper and lower covers are insertion engaged with the insertion holes on the main body to complete assembling of the key ring. The upper and lower covers are mutually connected at the middle peripheral sections of the lateral sides of the main body by the lateral wing pieces, these connecting areas will be the prying areas for dismantling the assembly of the key ring, the prying areas are hidden in the notches provided at the middle peripheral sections of the lateral sides of the main body in order to avoid prying the upper and lower covers during use.
