Description
Technical field
The utility model relates to a kind of plastic pipe production line cooling water water supply and sewage device.
Background technology
Current tubing industry production capacity surplus is serious; dog-eat-dog; tubing process design is unreasonable; especially the most distinct issues of tubing production equipment are that energy consumption is very high, and cause tubing production cost high, the finished product after dispatching from the factory is corresponding becomes very high; this is unfavorable for the development of industry; more mainly add energy consumption, do not meet the current requirement to environmental protection, to the requirement of energy-saving and emission-reduction.Main energy consumption on pipe production line is electric energy.Each working equipment all mainly electrical equipment.
Below describe existing pipeline production equipment feature and operation method.
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. 2, 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, production line energy consumption is high, and such pipe production line needs to be equipped with water supply motor and water pump, showerhead electrode water pump, drain motor water pump.Need the motor and water pump of use many, power consumption is large, and especially supply water motor and water pump, and will supply water to many production lines because considering, so the motor installed is heavy-duty motor, power consumption is very large.In addition showerhead electrode continuous firing, energy consumption is also very high.
4, 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.
5, 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.
