The utility model mainly solves the technical problem of providing a vacuum energy-saving double-screw extruder, which saves energy consumption on the premise of ensuring normal work by adopting vacuum adsorption of an intermittent vacuum pump, can realize quick overhaul of a vacuum tube, is convenient for normal operation of equipment, has excellent energy-saving effect and reduces processing cost.
In order to solve the technical problems, the utility model adopts a technical scheme that: provided is a vacuum energy-saving twin-screw extruder comprising: the vacuum collecting tank is connected to the extruder body through the vacuum pipe, a vacuum gauge and an adjusting valve are correspondingly arranged on the vacuum pipe respectively, the vacuum pump is correspondingly connected with the vacuum collecting tank, a time relay is correspondingly arranged on the vacuum pump, a hollowed-out maintenance opening is formed in the upper surface of the vacuum pipe, a flip cover is hinged to the maintenance opening, and a screen is arranged on the inner wall of the vacuum pipe below the maintenance opening on one side of the vacuum collecting tank.
In a preferred embodiment of the present invention, the access opening is arranged in a stepped structure.
In a preferred embodiment of the utility model, the edge of the flip cover is provided with a sealing gasket for sealing corresponding to the access opening.
In a preferred embodiment of the utility model, the upper surface of the flip cover is provided with a handle.
In a preferred embodiment of the utility model, the flip cover is further provided with a viewing window at one side of the screen.
In a preferred embodiment of the utility model, a ring-shaped gasket is welded on the inner wall of the vacuum tube on one side of the vacuum collection tank and corresponds to the screen for limiting.
The utility model has the beneficial effects that: according to the vacuum energy-saving double-screw extruder disclosed by the utility model, through vacuum adsorption of the intermittent vacuum pump, energy consumption is saved on the premise of ensuring normal work, the vacuum tube can be quickly overhauled, the normal operation of equipment is facilitated, the energy-saving effect is excellent, and meanwhile, the processing cost is reduced.
Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments are briefly introduced below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and other drawings can be obtained by those skilled in the art without inventive efforts, wherein:
FIG. 1 is a schematic structural view of a preferred embodiment of a vacuum energy-saving twin-screw extruder according to the present invention; fig. 2 is an enlarged view of fig. 1 at a.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, an embodiment of the present invention includes:
a vacuum energy-saving twin-screw extruder comprising: the extruder comprises an extruder body 1, a vacuum pump 2, a vacuum collection tank 3 and a vacuum pipe 4.
The vacuum collecting tank 3 is connected to the extruder body 1 through a vacuum pipe 4 and is used for collecting water vapor and dirt of materials in the extruder body 1. The vacuum tube 4 is correspondingly provided with a vacuum gauge 5 and an adjusting valve 6 respectively for monitoring the vacuum degree and adjusting the vacuum adsorption strength. The vacuum pump 2 is correspondingly connected with the vacuum collecting tank 3 and used for providing power for vacuumizing.
In addition, a time relay 7 is correspondingly arranged on the vacuum pump 2, and discontinuous vacuum adsorption is carried out for a short time according to the use, so that the use duration of the vacuum pump is reduced under the strength of vacuum adsorption, and the energy consumption is saved.
The upper surface of the vacuum tube 4 is provided with a hollowed-out access hole 8 for timely overhauling and cleaning when the vacuum tube 4 is blocked.
The access hole 8 is of a stepped structure and is provided with a flip cover 9 in an articulated manner so as to facilitate the placement of the flip cover 9, the edge of the flip cover 9 is provided with a sealing gasket 10 which is sealed correspondingly with the access hole 8, and the vacuum degree inside the vacuum tube 4 is ensured. The upper surface of the turnover cover 9 is provided with a handle 11, so that a worker can grab the cover conveniently.
The inner wall of the vacuum tube 4 is provided with a screen 12 below the access hole 8 on one side of the vacuum collection tank 3, so that the waste of raw materials and the use of saving raw materials are avoided for screening large granular materials. The inner wall of the vacuum pipe 4 is also welded with a ring of annular gaskets 13 on one side of the vacuum collection tank 3 to correspond to the screen 12 for limiting, so that the screen 12 is prevented from moving.
The flip cover 9 is also provided with an observation window 14 on one side of the screen 12, when a worker sees from the observation window 14 that materials are accumulated in the vacuum tube 4, the flip cover 9 can be opened in time to clean, so that a large amount of raw materials are prevented from being accumulated, and energy consumption is saved.
In conclusion, the vacuum energy-saving double-screw extruder provided by the utility model has the advantages that the vacuum adsorption of the intermittent vacuum pump is adopted, the energy consumption is saved on the premise of ensuring normal work, the vacuum pipe can be quickly overhauled, the normal operation of equipment is facilitated, the energy-saving effect is excellent, and the processing cost is reduced.
