The production process of tubing is as follows: after plastic cement raw material being carried out high temperature and dissolving, by extrusion apparatus extrusion molding, high temperature plastic cement pipeline after shaping is immediately by vacuum tank 1-2, cooling water is sprayed by shower nozzle 1-1 in vacuum tank, high temperature plastic pipe surrounding is sprayed, to reach cooling effect.Because ensureing that the plastic pipe under the condition of high temperature is indeformable, do not produce and break, so the cooling just having passed through the shaping plastic pipe of extrusion apparatus must in vacuum tank.See Fig. 1, cooling water passes through the water pump of constant power from circulating water pool diversion, then by entering in vacuum tank, after cooling, draws back circulating water pool again.
Such for the cooling procedure in vacuum tank: see Fig. 1, vacuum tank comprises the water spray chamber on top and the water tank of bottom, pass through for plastic pipe to be cooled in water spray chamber, while passing through, the shower nozzle being arranged on the water spray chamber left and right sides starts plastic pipe water-spraying control.Water spray the water got be water in the water tank of bottom, provide hydraulic pressure by showerhead electrode 1-3, the water after sprinkling is again in natural reflow tank.Outside water supply directly feeds in water tank, water uses at vacuum tank Inner eycle, serviceability temperature sensor 1-4 detects the water temperature in water tank, if water temperature is higher, start to feed cold water from outside in water tank, to reduce water temperature in water tank, adopt water level in water-level gauge 1-6 monitoring water tank, in order to keep water level in water tank, then opening draining pump 1-5, in water tank, directly discharging a part of water.
Existing pipeline production equipment (pipe production line) also exists following deficiency:
1, in vacuum tank, water temperature is high, and cooling effect is bad.
Because of the water natural reflow tank again after sprinkling, and then be forced into shower nozzle by water pump in water tank, water uses at vacuum tank Inner eycle, repeatedly spray high temperature plastic pipe, water temperature is all the time in higher state, not good enough to the cooling effect of tubing, affects quality and the cooling velocity of pipe finished.
2, because cooling effect is not good, but in order to ensure the quality of pipe material product most possibly, tubing must be reduced by the speed in vacuum tank, to extend cool time, correspondingly reducing the per unit area yield efficiency of pipe production line.
3, because drain motor mainly controls by water thermometer, when water temperature in water tank does not reach the temperature of draining setting, draining air pump inoperative or delayed work, cause water level in water tank higher; When draining pump Quick drainage during water temperature over-high in water tank, cause again water level in water tank too low, lack of water phenomenon in water tank is also often there is in actual production process, the direct generation the pressure in whole vacuum tank of water level height in water tank produces tremendous influence, the vacuum tank pressure of fluctuation directly can arrive the quality of pipe finished, causes defective work.
4, draining pump carries out drainage works with reference to water temperature, and its working condition is interrupted, and be very do not advise rate, is easily out of order.Whole production line downtime will be caused once be out of order.
In sum, in order to ensure pipe finished qualification rate, improving the quality of products, reducing production cost simultaneously, and enhance productivity, pipe production line needs a kind of with the design of new cooling vacuum case or cooling water design.

Detailed description of the invention
Utility model works is in the following manner:
In water inlet pipe, input hydraulic pressure, then open automatic valve, provide cooling water to spray-head interface 2-4, and in vacuum tank, inject cooling water by shower nozzle, after cool water shower plastic pipe, import bottom vacuum tank.
Water-level gauge detects the water level value bottom vacuum tank, and after water level value reaches designated water level, the current level value detected is sent in governor circuit by water-level gauge, governor circuit opening water discharge pump, draining outside case.
The water supply flow that governor circuit is detected by feed water flow gauge, and according to the water supply flow detected to regulate draining pump drain discharge.
When water-level gauge detects that water level is after the designated water level upper limit or lower limit, control circuit sends signal to draining pump, opens large or turns down draining pump flow, being in designated water level to keep actual water level in vacuum tank.In real work, when water level in vacuum tank is to peak place, in vacuum tank, the water yield is 1 cube, and the water level minimum point place water yield is 0.5 cube.
Open automatic valve, in vacuum tank, inject cool water shower plastic pipe, the cooling water entered is normal-temperature water, and its temperature, for being generally 8-30 degree, is about 160-175 degree Celsius by the tubing temperature squeezed out; By the spray of cooling water, make tubing, in vacuum tank, hull-skin temperature is reduced to less than 100 degrees Celsius, the cooling effect prestige recycled compared with high-temperature water in the vacuum tank in background technology improves more than 20%, namely tubing has stopped time shorten 20% in vacuum tank, get off like this, under the tubing of whole pipe production line, linear velocity also just improves 20%.
