Description

The water vapor separation system of vacuum cooled water tank for section bar extrusion
Technical field
The present invention relates to the vacuum extractor of vacuum cooled water tank for a kind of section bar extrusion, specifically the water vapor separation system of vacuum cooled water tank for a kind of section bar extrusion.
Background technology
It is wet vacuum cooling and shaping method that continuous extrusion plastic section bar is carried out to the good method of cooling and shaping, normally extruded plastic profile is undertaken cooling by vacuum cooled water tank water, for preventing because of the depression of the cooling profile wall causing and sinking, in the cooling interior space, set up unified negative pressure.Conventionally, cooling water need to flow to afterbody along section bar moving direction by the head from vacuum cooled water tank under the swabbing action of negative pressure, and is finally drawn out of vacuum cooled water tank.Therefore, this vacuum cooled water tank is typically provided with independently negative pressure device and water plug, and general negative pressure device adopts vavuum pump, and water plug adopts water pump.Because the required negative pressure of vacuum cooled water tank is larger, the noise and the vibration that during vavuum pump work, produce are very large, and vibrate the quality that can affect Surface of profile, and power consumption is large; Meanwhile, the moisture content of meeting suction part during vavuum pump work, the service life of having reduced vavuum pump.Water pump need continuously be worked in addition, and not only power consumption is large, also greatly reduces the service life of water pump simultaneously.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, the water vapor separation system of a kind of section bar extrusion with vacuum cooled water tank is provided, the vibratory output that negative pressure device produces vacuum cooled water tank is little, can not affect Surface of profile quality, but also can reduce power consumption.
The technical solution used in the present invention is: comprise that one for the seal case of aqueous vapor separation, casing upper end is provided with several and the vacuum cooled water tank bleeding point that interface communicates of bleeding;
Be arranged on the sealed air chamber at casing top, air chamber bottom has air inlet to communicate with cabinets cavity;
Negative pressure device, is used for to the air chamber formation negative pressure of bleeding;
Water pump, is used for extracting the ponding that is deposited in lower box;
And be arranged on the upper and lower liquid-level switch on wall box, be used for controlling water pump and extract off and on the ponding that is deposited in lower box.
Because negative pressure device produces negative pressure by air chamber is vacuumized to vacuum cooled water tank, noise and vibration that vacuum produces are applied directly on air chamber and seal case, and vacuum cooled water tank is exerted an influence hardly, can improve Surface of profile quality.And the pump house unoccupied place that is used for drawing water work, can save electricity, can increase the service life again.
Further, described negative pressure device is air blast.The present invention can select air blast as negative pressure device, and for vavuum pump, blower power is less, can reach the requirement of negative pressure value that high-power vavuum pump produces, also can save electricity.
Further, casing is around provided with to the dividing plate extending below casing at the air inlet that leads to air chamber, and the passage in the middle of dividing plate forms gas channel, makes the air inlet of gas channel be positioned at the bleeding point below on casing.To the gas channel of downward-extension, can make full use of the aqueous vapor separated space of casing top, do not need to increase air room height and can extend gas channel, so that aqueous vapor is separated better.
Preferably, dividing plate bottom at least extends to upper liquid level below in casing, and dividing plate is from having air admission hole close to upper liquid level top to the sidewall of bottom.This scheme can make full use of the aqueous vapor separated space of liquid level below, further extends gas channel.
Further, be provided with exhaust tube in casing, exhaust tube upper end extends in air chamber through gas channel, and exhaust tube lower end is connected with external air extractor through wall box.This scheme is because exhaust tube is arranged in casing, and compact conformation, saves space, is convenient to install and distribute on extrusioning shaping platform.
Further, the sealing of exhaust tube upper end, exhaust tube has air admission hole on the sidewall of gas indoor section.This structure can conveniently arrange vacuum meter at air chamber top, and the air-flow that enters exhaust tube can not produce and disturb vacuum meter, can prevent that the condensed water at air chamber top from dropping in exhaust tube simultaneously yet.
As shown from the above technical solution, the present invention has following beneficial effect: the one, and noise and vibration that negative pressure device vacuumizes generation are applied directly on air chamber and seal case, and vacuum cooled water tank is exerted an influence hardly, can improve Surface of profile quality.The 2nd, can adopt air blast to substitute vavuum pump and vacuumize, power consumption is less, and during work, vibration and noise are less; And the gas outlet of air blast can directly connect the air blowing pipeline of extrusioning shaping platform, for subsequent handling is dried up Surface of profile, dry up operation and do not need separately to establish blower fan, can save electricity.The 3rd, water pump intermittent work, can avoid water pump long time continuous working, extends the service life of water pump, has reduced maintenance cost, and production stability is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the top view of Fig. 1.
The specific embodiment
The present invention as depicted in figs. 1 and 2, supplies the seal case 1 of aqueous vapor separation to be rectangular-shaped, and casing arranges the sealed air chamber 2 raising up in the middle of 1 top, and air chamber 2 bottoms have air inlet 21 to communicate with casing 1 inner chamber; Casing 1 top arranges respectively two bleeding points 11 in air chamber 2 both sides along its length, and each bleeding point 11 can communicate with the interface of bleeding on vacuum cooled water tank by pipeline.
Casing 1 bottom one side is provided with pump mouth 16, by pipeline, is connected with water pump 4, and upper and lower liquid-level switch 12,13 is housed on casing 1 sidewall, is used for controlling water pump 4 and extracts with gap the ponding 8 that is deposited in casing 1 bottom.The delivery port 41 of water pump 4 communicates with the water storage box to vacuum cooled water tank cooling water supply by pipeline.
Casing 1 is provided with below casing and extends dividing plate 6 in air inlet 21 both sides of leading to air chamber 2, and dividing plate center-aisle forms gas channel 61, makes the air inlet of gas channel 61 be positioned at bleeding point 11 belows on casing.
For filling part, utilize space, extend gas channel 61, dividing plate 6 bottoms can extend to the position between upper and lower liquid-level switch 12,13, or lower position more.Dividing plate 6 is from having air admission hole 62 close to upper liquid level top to dividing plate 6 bottoms, and the gas being entered in casing 1 by bleeding point 11 can be entered in gas channel 61 by air admission hole 62, and upwards enters in air chamber 2.
Bleeding of both sides is also provided with the dividing plate 7 extending to casing below between interface 11, makes each bleeding point 11 below form independently passage, can extend the passage of aqueous vapor separation.
