Description
Technical field
The invention belongs to shaping platform field, particularly relate to a kind of shaping platform aqueous vapor separation method.
Background technology
Extrusion moulding is produced PVC door and window goods and is referred to: PVC material melts plastifies by extruder, and then fused materials is shaped to the door and window cross section blank of required specification in slit die, through shaping platform cooling and shaping, delivers to the packing of tilting trestle windrow after traction cutting.In this PVC production line, the Main Function of shaping platform provides cooling water and negative-pressure vacuum to shaper.
The length of domestic conventional shaping platform is generally 5 meters ~ 8 meters, along with improving constantly of extruder and Tool and Die Technology, its speed of production constantly promotes, also improve the cooling velocity to mould thereupon, but domestic existing shaping platform often lacks the effective ways processed the waste water and gas of the pump housing discharge producing negative-pressure vacuum, just waste water and waste gas are discharged to outside by skirt simply, and the waste water and gas high speed and high pressure of often pump housing discharge, this easily causes shaping platform and shakes excessive in section bar cooling and shaping process, produce huge noise, cause water resource waste simultaneously.
China Patent No. ZL201320559033.0, utility model name is called " a kind of door and window housing shaping platform ", it discloses this shaping platform and comprises cyclic water tank, cooling tower and pond, arrange pond below cooling tower; Described cyclic water tank is provided with some water inlets and delivery port, and water inlet is communicated with pond by inlet pipeline, and delivery port is communicated with cooling tower by outlet pipeline, and the water inlet end of inlet pipeline is provided with water circulating pump.Although this shaping platform can carry out effective cooling to door-window section bar, have ignored the process to waste water and gas, easily cause shaping platform to shake excessive, produce noise.
Summary of the invention
In order to solve the technical problem that vibrations in shaping platform cooling procedure that prior art exists are large, there is noise, the invention provides a kind of shaping platform aqueous vapor separation method, it can carry out aqueous vapor separation and noise reduction fast to the waste gas waste water that the pump housing is discharged.
The technical solution used in the present invention is as follows:
A kind of shaping platform aqueous vapor separation method, arranges hollow passageway and carries out centralized collection to the aqueous vapor that the pump housing is discharged below shaping platform frame, then connects upper exhaust section respectively by hollow passageway and lower draining section carries out aqueous vapor separating treatment.
In the present invention, have employed hollow passageway concentrates the waste water and gas to the shaping platform pump housing produces to collect, hollow passageway is very large and unimpeded, mainly one is played to aqueous vapor and guide cushioning effect, high speed and high pressure is also rapidly to lower draining section and the flowing of upper exhaust section with the aqueous vapor of heat in hollow passageway, upper exhaust section combustion gas, lower inlet segment collects waste water, in this process, their energy can decrease, can reduce the impact that passage causes in the space closed, the generation of huge noise can be avoided.
Described centralized collection process comprises: arrange the air inlet be connected with the pump housing in the left and right sides of hollow passageway, the aqueous vapor that the pump housing is discharged flows in the middle part of hollow passageway.
The pump housing adopted due to shaping platform and use various, the present invention is rationally provided with the connection of the pump housing and hollow passageway, makes them all flow in the middle part of hollow passageway, shortens the flow distance of aqueous vapor in hollow passageway as far as possible, carry out aqueous vapor separation as early as possible, avoid producing excessive vibrations.
In method, described aqueous vapor separating treatment process comprises: on the upside of hollow passageway, connect exhaust section, downside connects lower inlet segment, and lower inlet segment is connected collecting box, when aqueous vapor flows into collecting box toward hollow passageway toward waste water in the flow process of middle part from lower inlet segment, waste gas is discharged to the external world from upper exhaust section.
Present invention employs exhaust section to realize the effective of aqueous vapor with lower inlet segment and be separated, upper exhaust section combustion gas, lower inlet segment is collected waste water and is flowed into collecting box, waste water energy is accessed and processes use further, upper exhaust section be arranged so that most of gas can not enter in collecting box cause casing shake large, noise is large.
In method, on controlling before passing into pump housing aqueous vapor and entering hollow passageway, exhaust section and lower inlet segment are positioned at same central axis, and make lower inlet segment transverse width be greater than exhaust section.
In method, arrange and connect upper exhaust section on the upside of hollow passageway and specifically comprise: upper exhaust section structure is from top to bottom set gradually the extension for extending in hollow passageway, and it is outer and for overhanging section of being discharged by gas to be exposed at hollow passageway outward.
In the present invention, more ingenious to arranging of exhaust section on inside method, wherein extension is stretched in hollow passageway and is not only just discharged by waste gas, although most waste water directly can flow into collecting box by lower draining section, but have part water to be mixed in gas or due to water speed too fast, continue to flow forward in passage, and the existence of extension just play intercept this part aqueous vapor flow forward, make it toward current downflow, gas is then from overhanging section of discharge of upper exhaust section, and moisture then flows in collecting box.Such structure can be separated aqueous vapor effectively rapidly, such that the vibrations in casing are little, noise is low.
In method, the degree of depth that hollow passageway is stretched in described extension is less than the vertical degree of depth of hollow passageway.In the present invention, the vertical degree of depth that the degree of depth of extension is less than hollow passageway is in order to avoid gas can not be discharged completely from upper exhaust section, and be incorporated in casing to cause with moisture and shake and noise, the scope of the degree of depth optimum of extension generally can be controlled in 1/3 to 3/4 of the vertical degree of depth of hollow passageway, optimal value can be 1/2 of the vertical degree of depth of hollow passageway, but these do not do unique restriction of the present invention, other scope all belongs to that the present invention contains.
The tilting section with ramp structure is set to by described overhanging section, and last horizontal segment gas being entered the external world.
In the present invention, improve on the effect basis being arranged on its degassing function of overhanging section inside method, consider that the waste gas pressure of discharging the external world is higher, impulse force is larger, and there is high temperature, easy accidental injury workman, therefore overhanging section includes tilting section, this tilting section can play the effect of buffer gas impulse force, waste gas impulse force is reduced, and this process also reduces EGT, is finally discharged extraneous again by horizontal segment, and the setting of horizontal segment is mainly in order to mate shaping platform frame, the waste gas of discharge is also made to be flushed to frame.
Collecting box sidewall arranges the window of water level in observable casing.
Connected by air inlet on the left of hollow passageway and be used for the vavuum pump cooling section bar, the air inlet on right side connects the turbulence pump for discharging eddy current.
Compared with prior art, the beneficial effect that the present invention has: realize being separated to the waste gas waste water of the pump housing, and vibrations and the noise of shaping platform can be greatly reduced, simple to operate.
