Description
Technical Field
The utility model belongs to the technical field of the extruding machine technique and specifically relates to an automatic extruding machine evacuation system who supplies water.
Background
In the plastics industry, a plastics extruder (hereinafter referred to as an extruder) is a core device which is conventionally necessary. In the working process of the extruding machine, plastic raw materials (mainly powder and granules) are heated and extruded by a screw rod and then are extruded and molded from a head die. When the plastic raw materials are put into an extruder for production, certain moisture and some low-molecular impurities are contained, the plastic raw materials are heated and evaporated to be in a gas state in the extrusion process, and if the water vapor and the gaseous impurities are not discharged, the surface of a product is not smooth, and the electrical performance of the product is also influenced.
The extruder is vacuumized inside by a water ring vacuum pump, and water vapor and gaseous impurities are pumped out. A water supply pipeline of the existing water ring vacuum pump is provided with a manual valve, and if a worker forgets to open the manual valve in the vacuum pumping process, negative pressure cannot be formed in the water ring vacuum pump, and the water ring vacuum pump cannot be pumped; after the water ring vacuum pump is shut down, if forget to close the manual valve, because the special structure of water ring vacuum pump, water can follow the water ring vacuum pump and flow backward into the extruder along the pipeline, lead to the product to scrap, can damage the extruder even, cause serious production accident.
Disclosure of Invention
The utility model aims at overcoming not enough among the above-mentioned background art, providing an automatic extruding machine evacuation system that supplies water, can effectively avoid the water of water supply pipe to get into the extruding machine to and do not supply water and lead to the problem of the unable evacuation of water ring vacuum pump idle running, still have simple structure, convenient to use's technical characterstic.
The utility model adopts the technical scheme as follows: the utility model provides an automatic extruding machine evacuation system of water supply, includes water ring vacuum pump, to the water supply pipe of water ring vacuum pump water supply to and install the manual valve on the water supply pipe, the admission line of water ring vacuum pump is connected with the barrel inner chamber of extruding machine, and this water ring vacuum pump takes out behind the gas of barrel inner chamber the exhaust duct discharge, still be provided with the solenoid valve for water on the water supply pipe, this solenoid valve for water is located between manual valve and the water ring vacuum pump, receives the start switch control of water ring vacuum pump, starts or stops simultaneously with the water ring vacuum pump.
Preferably, the air inlet pipeline consists of a first air inlet pipe, a buffer tank and a second air inlet pipe, the first air inlet pipe is connected with the inner cavity of the machine barrel and the top of the buffer tank, and the second air inlet pipe is connected with the air inlet of the water ring vacuum pump and the top of the buffer tank.
The utility model has the advantages that: the utility model discloses set up water solenoid valve behind manual valve, start simultaneously with water ring vacuum pump and pipe wall simultaneously, avoid setting up a manual valve alone but not open and lead to the idle running of water ring vacuum pump to and the water backflow problem that manual valve did not close and lead to when shutting down. In addition, the buffer tank can separate gas from solid and liquid impurities so as to avoid influencing the normal work of the water ring vacuum pump, and also avoid the impact of sudden vacuumizing on materials in the machine barrel when the water ring vacuum pump is started, so that the whole structure is simple and the use is convenient.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
The figure shows that: the device comprises a first air inlet pipe 1, a buffer tank 2, a second air inlet pipe 3, a water ring vacuum pump 4, an exhaust pipeline 5, a water electromagnetic valve 6, a manual valve 7 and a starting switch K.
Detailed Description
To make the objects, technical solutions and advantages of the present invention more clearly understood by those skilled in the art, the present invention will be further described with reference to the accompanying drawings and examples, but the present invention is not limited to the following examples.
In the description of the present invention, it should be noted that unless otherwise explicitly specified or limited, the indicated orientations or positional relationships are based on the orientations or positional relationships shown in the drawings and are only for convenience of description and simplicity of description, and do not indicate or imply that the indicated devices or elements must have a particular orientation, be constructed in a particular orientation, and be operated. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1, the utility model provides a pair of extruding machine evacuation system of automatic water supply, including water ring vacuum pump 4, to the water supply pipe of water ring vacuum pump 4 water supply to and install manual valve 7 on the water supply pipe, the admission line of water ring vacuum pump 4 is connected with the barrel inner chamber of extruding machine (invisible in the figure), and this water ring vacuum pump 4 is taken out behind the gas of barrel inner chamber and is discharged from exhaust duct 5. The water supply pipeline is also provided with a water electromagnetic valve 6, the water electromagnetic valve 6 is positioned between the manual valve 7 and the water ring vacuum pump 4, and a power supply line of the water electromagnetic valve 6 is connected to a starting switch K of the water ring vacuum pump 4, is controlled by the starting switch K of the water ring vacuum pump 4, and is started or stopped simultaneously with the water ring vacuum pump 4. The water electromagnetic valve 6 is an existing mature product, is in a closed state when being powered off, is opened after being powered on, and can be obtained commercially.
The air inlet pipeline is composed of a first air inlet pipe 1, a buffer tank 2 and a second air inlet pipe 3, the first air inlet pipe 1 is connected with the inner cavity of the machine barrel and the top of the buffer tank 2, and the second air inlet pipe 3 is connected with the air inlet of the water ring vacuum pump 4 and the top of the buffer tank 2.
