Abstract
The present invention discloses a method for producing vacuums by the waste steam of plastic forming machines. A waste steam discharge pipe of a mould of an expansion plastic forming machine is introduced into a vacuum tank, wherein the top of the vacuum tank is provided with a cooling water jet pipe and a vacuum meter, the top or the side edge of the vacuum tank is provided with a vacuum pipe, and the bottom of the vacuum tank is provided with a drainage pipe; the vacuum pipe of the vacuum tank is connected with a vacuum pipe of the mould of the expansion plastic forming machine. The method comprises the following steps: steam enters the mould of the expansion plastic forming machine; the discharged waste steam enters the vacuum tank; cooling water is sprayed onto the vacuum tank; the volume of the waste steam in the vacuum tank is quickly reduced in the process of cooling in order to produce a vacuum in the vacuum tank, and moisture in expanded plastic products in the mould is absorbed into the vacuum tank via the vacuum pipe. With the present invention, the waste steam of the expansion plastic forming machine can be secondarily developed and utilized and can also be used for replacing a vacuum pump to produce a vacuum, and energy is saved.
Description
Technical field
The present invention relates to make the method for vacuum, particularly a kind of method of utilizing the expansion plastic forming machine waste vapour to make vacuum.
Background technology
Expansion plastic forming machine is in the technical process of making the expansion plastic product, in the mould of plastic grain injection molding machine, through technological processes such as heating, expansion, moulding, cooling, vacuum.Wherein, the medium of heating is a steam.The steam that the boiler output is about 120 ℃ enters in the mould, make the rapid expansion molding of plastics material after, in mould, inject the water cooling product again, the vacuum of utilizing vavuum pump to make is then extracted the moisture content of product in the mould out.The shortcoming of above-mentioned flow process is: the exhaust steam after entering steam that mold heated uses and discharging, still have the temperature more than 100 ℃, and cause the waste of the energy.
Summary of the invention
The objective of the invention is at above-mentioned shortcoming, work out a kind of method of utilizing waste steam of expansion plastic forming machine to make vacuum, both can the exhaust steam utilization, can replace vavuum pump to make vacuum again, energy savings is killed two birds with one stone.
The object of the present invention is achieved like this: the exhaust steam discharge pipe on the expansion plastic forming machine mould is introduced vacuum tank.Vacuum tank is a container that sealing is withstand voltage.The top of vacuum tank is provided with cooling water playpipe and vacuum meter, and the top or the side of vacuum tank are provided with vacuum tube, and the vacuum tube process valve of vacuum tank is extended for the vacuum tube of vacuum tank again, and is connected with total vacuum tank of stocking vacuum.The bottom of vacuum tank is provided with drainpipe.The vacuum tube of vacuum tank is connected with the vacuum tube of expansion plastic forming machine mould.The vacuum tube of every vacuum tank is connected with total vacuum tank of stocking vacuum.Injected plastic particle in the expansion plastic forming machine mould, the steam that the boiler output is about 120 ℃ enters pipe from steam and enters the expansion plastic forming machine mould, makes plastic grain melt the product that foaming and intumescing becomes the strong yet lightweight.After the exhaust steam that the expansion plastic forming machine mould is discharged enters vacuum tank from the valve of exhaust steam discharge pipe through pressure-reducing valve, close the valve of exhaust steam discharge pipe.Open the valve of cooling water playpipe, after vacuum tank sprays an amount of cooling water, close the valve of cooling water playpipe.Exhaust steam in vacuum tank volume in cooling dwindles rapidly, makes and produces vacuum in the vacuum tank.Open the valve of the vacuum tube of the valve of vacuum tube of vacuum tank and mould, the moisture content in the water-cooled expansion plastic product that is cooled in the mould is inhaled into vacuum tank through vacuum tube.The valve of the vacuum tube of closing molding takes out the expansion plastic product in the mould.Open the valve of total vacuum tank, remaining vacuum is imported into vacuum in total vacuum tank standby by vacuum tube in the vacuum tank.Close the valve of the vacuum tube of vacuum tank, open the valve of drainpipe of the bottom of vacuum tank, discharge cooling water.
Owing to adopt the present invention, the exhaust steam that makes expansion plastic forming machine both can second development and utilization, can replace vavuum pump to make vacuum, energy savings again.
