Summary of the invention
The technical problems to be solved in the utility model is, provides a kind of carry out extrusion dehydration, energy-efficient screw extruder that can be used for materials such as municipal garbages.
The utility model solves the technical scheme that its technical problem adopts: construct a kind of screw extruder for extrusion dehydration, comprise housing, shaftless screw assembly and valve plate, the Shaftless spiral blade of shaftless screw assembly is positioned at housing, by completing being fed forward of material without the rotation of all helical blades, the first half of enclosure interior is the cylindrical shell for support material, the latter half of enclosure interior is the screen drum of band eyelet, described valve plate is hinged on the tail end of housing, material is in screen drum and be constantly squeezed effect, thus reach the object of Separation of Solid and Liquid gradually, the eyelet of the waste water be separated on screen drum is discharged, and finished product materials is accumulated in the screen drum of enclosure interior, after its active force is enough to overcome the deadweight of housing afterbody valve plate, valve plate turns to be opened.
In such scheme, described shaftless screw assembly also comprises: motor, reductor, bearing block and power transmission shaft, and described motor via reducer, bearing block are connected with described Shaftless spiral blade with power transmission shaft.
In such scheme, the charge level of meeting of described Shaftless spiral blade is blunt fillet, and back of the body charge level is pointed corner cut.
In such scheme, described motor is frequency control motor.
Implement the screw extruder for extrusion dehydration of the present utility model, there is following beneficial effect:
1, complete being fed forward of material by the rotation of Shaftless spiral blade, Shaftless spiral blade there will not be bridging putty phenomenon in running.
2, material to be constantly squeezed effect in screen drum, thus reach the object of Separation of Solid and Liquid gradually, the eyelet of the waste water be separated on screen drum is discharged, and finished product materials is accumulated in the screen drum of enclosure interior, after its active force is enough to overcome the deadweight of housing afterbody valve plate, material is by valve plate device for transferring.The utility model has filled up existing equipment carries out dewatering operation blank to municipal garbage, and its dewatering efficiency is high, good, convenient for installation and maintenance to the adaptability of material.The utility model is specially adapted to process the extrusion dehydration operation through solid waste such as preliminary broken municipal garbages.

Detailed description of the invention
In order to there be understanding clearly to technical characteristic of the present utility model, object and effect, now contrast accompanying drawing and describe detailed description of the invention of the present utility model in detail.
As Figure 1-Figure 4, the utility model comprises housing 2, shaftless screw assembly 3, screen drum 4, valve plate 5 for the screw extruder of extrusion dehydration.
Shaftless screw assembly 3 in the utility model drive in rotary manner material cylindrical shell 1 and be covered with eyelet screen drum 4 in moved to discharge end by feed end, the first half of housing 2 inside is the cylindrical shell 1 for support material, the latter half of housing 2 inside is the screen drum 4 of band eyelet, discharge end is provided with valve plate 5, and valve plate 5 is hinged on the tail end of housing 2.When material arrive valve plate 5 place but active force be not enough to overcome valve plate 5 conduct oneself with dignity time, material is accumulated in screen drum 4, and the promotion squeezing action being constantly subject to new material is to complete dewatering operation.Treat to a certain extent, material overcomes the deadweight of valve plate 5, and valve plate 5 is backed down, and the material after extrusion dehydration is by valve plate 5 device for transferring.
Often organize shaftless screw assembly 3 and comprise motor 6, reductor 7, bearing block 8, power transmission shaft 9 and Shaftless spiral blade 10, many group shaftless screw assemblies 3 are placed side by side, and motor 6 drives Shaftless spiral blade 10 to rotate.Shaftless spiral blade 10 adopts special process to make, and Shaftless spiral blade 10 effectively can avoid bridging, putty situation, the utility model is particularly suitable for the extrusion dehydration job requirements of the solid waste such as municipal garbage and other prehensile, the stronger material of caking property.The utility model motor 6 level can be selected to install (Fig. 1-Fig. 3) according to technology arrangement demand or motor is vertically installed (Fig. 4-Fig. 6).
The charge level of meeting that Shaftless spiral blade 10 is designed to throughput direction from blade is supported or opposed the entrance angle of charge level with certain radian, meeting charge level and carrying on the back charge level of Shaftless spiral blade 10 is designed to blunt fillet and pointed corner cut respectively, can reduce spiral in rotary course with the friction of housing cylinder 1, reduce power consumption penalty, be convenient to large sheet, strip-shaped materials in course of conveying and clamp between blade 10 and cylindrical shell 1 by arranging entrance angle and shred simultaneously.
Further, in the utility model, motor 6 adopts frequency control motor, can adjust frequency, boost productivity for the characteristic variations of material, made equipment possess like this low energy consumption, high efficiency, the high-quality characteristic that features simple structure is easily exchanged.In addition, the utility model, while completing dewatering operation, can also reach the effect of convey materials, and the initial stage of having saved project construction undoubtedly drops into, and this also makes this equipment have a good application prospect.
By reference to the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; instead of it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; do not departing under the ambit that the utility model aim and claim protect, also can make a lot of form, these all belong within protection of the present utility model.
