Description
Technical field
The present invention relates to a kind of equipment of leather processing, a kind of specifically vacuum drier that leather is carried out drying.
Background technology
Relevant by retrieval patent documentation does not retrieve a kind of low temperature vacuum drier identical with structure of the present invention at present as yet.In leather-making technology,, need remove the processing of moisture to leather in order further leather to be processed.Existing processing method generally takes vacuum drier to process.Known vacuum drier operating 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 vacuum drier is when work, cover cap and working plate form a vacuum chamber, in vacuum chamber, leather moisture evaporated, the residual liquid of overflow sending out from leather itself, comprise the water liquid of staying platen when cleaning table top, all, enter vavuum pump cyclic water tank or outer outlet again by the direct suction vavuum pump of vacuum line.Because gas, waste liquid enter vavuum pump together, vavuum pump recirculated water is vaporized easily on the one hand, causes vacuum 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 is reduced, and shortened the service life of vavuum pump, thereby influenced the quality of leather, so be necessary existing vacuum drier is improved, to satisfy demand of practical production.
Summary of the invention
The objective of the invention is to provide a kind of improvement on existing vacuum drier basis, it is low to have heating-up 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 invention 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 pipe 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 exhaust outlet of receipts flow container respectively with vavuum pump I, the vavuum pump II company of passing through mutually; The exhaust outlet of described receipts flow container is provided with the control valve by control system control; Arrival end at vavuum 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 vavuum pump I is oily circulating vacuum pump.Described vavuum 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 control panel of described control system is the version of touch-screen, and its control panel is provided with oil level gauge tap, temp control switch.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 oily circulating vacuum pump.The leather of need processing is tiled on the upper surface of ground floor working plate, treat that tiling is full after, press the control system button, will move on the ground floor 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 ground floor working plate lower end, completes the leather of all working platen as the method.Under the effect of oily circulating 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 pipe 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 vavuum pump, the uncooled gas of condensate liquid 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 oily circulating vacuum pump under the effect of oily circulating 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 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 oily circulating 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.
Advantage of the present invention is: because the periphery of working plate is provided with the cooling pipe that links to each other with the prime condenser system, thereby when the steam of leather evaporation has just just become liquid to vacuum passage, 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 service life of cushion rubber effectively, has improved sealing property; Owing to adopt oily circulating vacuum pump to vacuumize, compare with existing water circulating vacuum pump, have the vaporization of being difficult for, guarantee its sealing, can form the advantage of powerful lasting vacuum; Owing to adopt oily circulating 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 flexibility 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 fluid pressure line breaks, joint becomes flexible, comes off, and hydraulic valve is malfunctioning when waiting contingency to take place to operating personnel'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, easy to operate, superior performance are so there is very big practical and popularizing value.
