Description
Technical field
The present invention relates to a kind of vacuum extractor of section bar extrusion vacuum cooled water tank, specifically a kind of water vapor separation system of section bar extrusion vacuum cooled water tank.
Background technology
Carrying out the good method of cooling and shaping to continuous extrusion plastic section bar is wet vacuum cooling and shaping method, namely normally extruded plastic profile is cooled by vacuum cooled water tank water, for preventing the depression because cooling the profile wall caused and sinking, in the cooling interior space, set up unified negative pressure.Usually, cooling water needs to flow to afterbody from the head of vacuum cooled water tank along section bar moving direction 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.Needed for vacuum cooled water tank, negative pressure is comparatively large, and the noise produced during vavuum pump work and vibration are very large, and vibration can affect the quality of Surface of profile, and power consumption is large; Meanwhile, during vavuum pump work, the moisture content of meeting suction part, reduces the service life of vavuum pump.Water pump need continuously work 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, provide a kind of water vapor separation system of section bar extrusion vacuum cooled water tank, the vibratory output that negative pressure device produces vacuum cooled water tank is little, can not affect section bar surface quality, but also can reduce power consumption.
The technical solution used in the present invention is: comprise a seal case be separated for aqueous vapor, casing upper end is provided with several bleeding point communicated with vacuum cooled water tank suction interface;
Be arranged on the sealed air chamber at casing top, bottom air chamber, have air inlet to communicate with cabinets cavity;
Negative pressure device, is used for bleeding formation negative pressure to air chamber;
Water pump, is used for extracting the ponding being deposited in lower box;
And the upper and lower liquid-level switch be arranged on wall box, be used for controlling water pump and extract the ponding being deposited in lower box off and on.
Because negative pressure device produces negative pressure by vacuumizing air chamber to vacuum cooled water tank, the noise that vacuum produces and vibration are applied directly on air chamber and seal case, have an impact hardly, can improve Surface of profile quality to vacuum cooled water tank.And the pump house unoccupied place being used for drawing water work, namely 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 powerful vacuum pump produce the requirement of negative pressure value, also can save electricity.
Further, casing is leading to the dividing plate being provided with around the air inlet of air chamber and extending below casing, and the passage in the middle of dividing plate forms gas channel, below the bleeding point that the air inlet of gas channel is positioned on casing.To the gas channel of downward-extension, the aqueous vapor separated space above casing can be made full use of, not need to increase air room height and can extend gas channel, so that aqueous vapor is separated better.
Preferably, at least extend to bottom dividing plate in casing below upper liquid level, dividing plate has air admission hole from close to above upper liquid level to the sidewall of bottom.This scheme can make full use of the aqueous vapor separated space below liquid level, extends gas channel further.
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 arranged in casing due to exhaust tube, compact conformation, saves space, is convenient to install distribution on extrusioning shaping platform.
Further, exhaust tube upper end seals, and the sidewall that exhaust tube divides at plenum interior has air admission hole.This structure conveniently can arrange vacuum meter at air chamber top, and the air-flow entering exhaust tube can not produce interference to vacuum meter, also can prevent the condensed water at air chamber top from dropping in exhaust tube simultaneously.
As shown from the above technical solution, the present invention has following beneficial effect: one is that negative pressure device vacuumizes the noise of generation and vibration is applied directly on air chamber and seal case, has an impact hardly, can improve Surface of profile quality to vacuum cooled water tank.Two is to adopt air blast to substitute vacuum pump evacuation, and power consumption is less, during work vibration and noise less; And the gas outlet of air blast directly can connect the air blowing pipeline of extrusioning shaping platform, for drying up Surface of profile subsequent handling, drying up operation does not need separately to establish blower fan, can save electricity.Three is water pump intermittent works, can avoid water pump long time continuous working, and extend the service life of water pump, reduce maintenance cost, 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.
Detailed description of the invention
As depicted in figs. 1 and 2, the seal case 1 be separated for aqueous vapor is rectangular-shaped, arranges the sealed air chamber 2 raised up, have air inlet 21 to communicate with casing 1 inner chamber bottom air chamber 2 in the middle of casing 1 top in the present invention; Casing 1 top arranges two bleeding points 11 respectively in air chamber 2 both sides along its length, and each bleeding point 11 communicates with the suction interface on vacuum cooled water tank by pipeline.
Bottom casing 1, side is provided with pump mouth 16, is connected with water pump 4 by pipeline, casing 1 sidewall is equipped with upper and lower liquid-level switch 12,13, is used for controlling water pump 4 and extracts the ponding 8 being deposited in casing 1 bottom with gap.The delivery port 41 of water pump 4 is communicated with the water storage box to vacuum cooled water tank cooling water supply by pipeline.
Casing 1 is provided with in air inlet 21 both sides leading to air chamber 2 and extends dividing plate 6 below casing, and dividing plate center-aisle forms gas channel 61, below the bleeding point 11 that the air inlet of gas channel 61 is positioned on casing.
Utilizing space for filling part, extending gas channel 61, the position between upper and lower liquid-level switch 12,13 bottom dividing plate 6, can be extended to, or more lower position.Dividing plate 6 has air admission hole 62 from close to above upper liquid level to dividing plate 6, and the gas 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.
Also be provided with the dividing plate 7 extended below casing between the suction interface 11 of both sides, make to form independently passage below each bleeding point 11, the passage that aqueous vapor is separated can be extended.
Negative pressure device is air blast 3.
Exhaust tube 5 is located in casing 1, and exhaust tube 5 upper end extends in air chamber 1 through gas channel 61, and casing 1 sidewall is provided with the bleeding point 14 communicated with exhaust tube 5 lower end, is connected with air blast 3 through external pipeline.
Blower export 31 can install the noise that muffler sends to prevent outer air-discharging additional, or directly connects the air blowing pipeline of extrusioning shaping platform, for drying up Surface of profile subsequent handling.
