Description
Technical field
The utility model relates to a kind of equipment of leather processing, a kind of specifically leather is carried out the exsiccant Vacuumdrier.
Background technology
Relevant by retrieval patent documentation does not retrieve the low temperature vacuum drier identical with the utility model structure at present as yet.In leather-making technology,, need remove the processing of moisture to leather in order further leather to be processed.Existing treatment process generally takes Vacuumdrier to process.Known Vacuumdrier working temperature is generally at 80 ℃～95 ℃, because temperature is higher, processing back leather is organized easily and sustained damage, and dried leather hardens, stiff, thereby influenced the quality of leather.And known Vacuumdrier is when work, cover cap and working plate form a vacuum chamber, in vacuum chamber, leather moisture evaporated, the debris of overflow sending out from leather itself, comprise the water liquid of staying platen when cleaning table top, all, enter vacuum pump cyclic water tank or outer relief outlet again by the direct suction vacuum pump of vacuum-lines.Because gas, waste liquid enter vacuum pump together, vacuum pump recirculated water is vaporized easily on the one hand, causes vacuum tightness to reduce; On the other hand, owing to contain various corrosion chemical substances in the waste liquid, the pump housing is corroded easily, increased the gap of the impeller and the pump housing, vacuum tightness is reduced, and shortened the work-ing life of vacuum pump, thereby influenced the quality of leather, so be necessary existing Vacuumdrier is improved, to satisfy demand of practical production.
Summary of the invention
The purpose of this utility model is that a kind of improvement on existing Vacuumdrier basis will be provided, and it is low to have Heating temperature, vacuumizes the efficient height, can prolong a kind of low temperature vacuum drier of service life of equipment effectively.
Technical characterictic of the present utility model is: considering dependable performance, be designed to comprise cover cap on the basis of protection leather quality and one deck can airtight mutually working plate at least; Cover cap is contained on the frame, and is mutually airtight with the top layer working plate, and working plate is lifted on the frame by oil cylinder; The inside of described every layer working plate is provided with heater block, and heater block links to each other with heating system; The periphery of working plate be provided with the cooling duct that links to each other with the prime condenser system and with receive flow container mutually the company of passing through vacuumize the duct; The liquid outlet of receiving flow container respectively with sump pit companys of passing through mutually, the venting port of receipts flow container respectively with vacuum pump I, the vacuum pump II company of passing through mutually; The venting port of described receipts flow container is provided with the control valve by Controlling System control; Inlet end at vacuum pump II is provided with back level condenser; On the column of frame, also be provided with at least two safety locking motions that prevent that working plate from gliding.Be provided with the seal closure that is used to seal around the lower end of described working plate.Described vacuum pump I is oil circulation vacuum pump.Described vacuum pump II is a Roots vaccum pump.The piston rod joint face of the oil cylinder that described frame links to each other with working plate adopts ball ring to be connected.The guide pin bushing that the piston cylinder of described oil cylinder links to each other with working plate is the sphere guide pin bushing.
During work, the opening control heat button, the heating tube valve open heats every layer of working plate respectively.Simultaneously, start oil circulation vacuum pump.The leather of need processing is tiled on the upper surface of the first layer working plate, treat that tiling is full after, press the Controlling System button, will move on the first layer working plate, compress with cover cap; Tiling leather to be processed on second layer working plate will move on the second layer working plate again, compresses with the cushion rubber of the seal closure of the first layer working plate lower end, completes the leather of all working platen as this method.Under the effect of oil circulation vacuum pump, steam in the leather begins to flow to the working plate periphery, enter the duct of working plate periphery, because the periphery of working plate is provided with the cooling duct that links to each other with the prime condenser system, when treating that steam enters working plate peripheral, be condensed very soon, under the effect of vacuum pump, the uncooled gas of phlegma and part enters the receipts flow container.After liquid, vapour entered and receives flow container, liquid entered sump pit through check valve, and gas enters oil circulation vacuum pump under the effect of oil circulation vacuum pump, and the liquid income of generation is received flow container, enters sump pit, and gas enters the exhaust tank discharging after being introduced into and receiving flow container again.After treating that vacuum tightness reaches certain numerical value, system starts the further gas clean-up of Roots vaccum pump, gas enters back level condenser before the Roots vaccum pump by pipeline, condensed liquid is admitted to the receipts flow container and enters sump pit again, the gas of failing to liquefy enters Roots vaccum pump, enters oil circulation vacuum pump again by Roots vaccum pump and handles, and forms liquids and gases, liquid enters receives flow container, sump pit, and gas is discharged after receiving flow container, exhaust tank.
The utility model has the advantages that: because the periphery of working plate is provided with the cooling duct that links to each other with the prime condenser system, thereby when the steam of leather evaporation has just just become liquid to vacuum tunnel, quickened the leather evaporation, improved efficient, reduced the temperature of working plate periphery simultaneously, the cushion rubber that is used in sealing is difficult for wearing out, and has prolonged the work-ing life of cushion rubber effectively, has improved sealing property; Owing to adopt oil circulation vacuum pump to vacuumize, compare with existing water cycle vacuum pump, have the vaporization of being difficult for, guarantee its stopping property, can form the advantage of powerful persistent vacuum tightness; Owing to adopt oil circulation vacuum pump to combine, thereby improved the ability that vacuumizes, reduced energy consumption with Roots vaccum pump; Because the oil cylinder piston bar of traction working plate is fixed on the top of frame, makes cylinder body sagging naturally; Because the employing sphere is connected between piston rod and column, cylinder body and the working plate, thereby guarantee the handiness of the upper and lower motion of working plate, prolonged the life-span of oil cylinder and entire equipment; Owing to be provided with safety locking motion on the column of frame, thereby avoided because of hydraulicefficiency pipeline breaks, joint becomes flexible, comes off, and hydraulicvalve is malfunctioning when waiting mishap to take place to operator's injury; Because the whole gas clean-up that adopts increases measures such as condenser system, makes the leather processing temperature be reduced to 30-70 ℃, thereby has eliminated the damage to the leather tissue, reduced that dried leather hardens, phenomenon such as stiff, leather quality is obviously improved; Because rational in infrastructure, superior performance is so there is very big practical and popularizing value.
