Abstract
The utility model discloses a rotary hollow screw shaft specially used for the civil explosion industry, belonging to the field of civil explosive device manufacturing equipment. The rotary hollow screw shaft structurally comprises a hollow shaft and double helical blades, wherein the double helical blades are welded on the surface of the hollow shaft; two ends of the hollow shaft are connected with spindles; a core tube is arranged in the hollow shaft; one end of the core tube is fixedly connected with one spindle, and the other end of the core tube is disconnected with the spindle at the other end of the hollow shaft; the two spindles at the two ends of the hollow shaft are both arranged on bearings; and swivel joints are arranged on the spindles at the two ends of the hollow shaft. Compared with the prior art, the utility model has the advantages that the rotary hollow screw shaft especially used for the civil explosion industry has a reasonable design, is easy to manufacture, is convenient to install, is safe and reliable and the like; and the rotary hollow screw shaft has the conveying as well as cooling functions, is reliably sealed and causes no leakage.
Description
Technical field
The utility model relates to civil explosive material making apparatus field, specifically a kind of rotation cored screw axle that is exclusively used in the quick-fried industry of the people.
Background technology
The conveyor screw that the quick-fried industry of the current people is used is the load transfer device between each operation of contact on the commercial explosive manufacturing line.Original conveyor screw is packing seal, and it is unreliable to seal, the mechanical part complex design; Be not easy to trouble removal, because sealing is unreliable, the cooling water flow of leakage is to ground, worker-house; The humidity in worker-house is increased, and commercial explosive absorbs moisture easily and causes explosive property to descend, and influences product design; Also might cause the production operation personnel to slide into, have potential safety hazard.
Summary of the invention
The technical assignment of the utility model is to above weak point, and a kind of rotation cored screw axle of rational in infrastructure, easy for installation, the safe and reliable quick-fried industry of a kind of people of being exclusively used in is provided.
The utility model solves the technical scheme that its technical matters adopted: this rotation cored screw axle comprises hollow shaft and double helix sheet; The double helix sheet is welded on the surface of hollow shaft; The two ends of hollow shaft are connected with mandrel; Be provided with the core pipe in the hollow shaft, an end of core pipe is captiveed joint with mandrel, and the mandrel of the other end of core pipe and the hollow shaft other end breaks off; The mandrel at hollow shaft two ends all is installed on the bearing, and swivel joint all is installed on the mandrel at hollow shaft two ends.
The center of described mandrel and core pipe axially is provided with water channel, and the water channel of core pipe is communicated with the water channel of bonded assembly mandrel; Swivel joint is provided with water inlet, and water inlet is communicated with the water channel of mandrel; Be provided with inner chamber in the double helix sheet, the water channel of mandrel is communicated with the inner chamber of double helix sheet through the apopore that is arranged on the hollow shaft.
The rotation cored screw axle of the quick-fried industry of a kind of people of being exclusively used in of the utility model is compared with prior art, have reasonable in design, be easy to processing, characteristics such as easy for installation, safe and reliable, existing conveying function also has refrigerating function concurrently, and seals reliable no leak.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing 1 is a kind of structural representation that is exclusively used in the rotation cored screw axle of the quick-fried industry of the people.
Accompanying drawing 2 be in the accompanying drawing 1 A to the sectional structure scheme drawing.
Among the figure: 1, mandrel, 2, the core pipe, 3, the double helix sheet, 4, bearing, 5, swivel joint, 6, hollow shaft, 7, apopore, 8, water channel, 9, water inlet.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
A kind of rotation cored screw axle that is exclusively used in the quick-fried industry of the people of the utility model; Its structure comprises hollow shaft 6 and double helix sheet 3; Double helix sheet 3 is welded on the surface of hollow shaft 6, and the two ends of hollow shaft 6 are connected with mandrel 1, are provided with core pipe 2 in the hollow shaft 6; One end of core pipe 2 is captiveed joint with mandrel 1, and the mandrel 1 of the other end of core pipe 2 and hollow shaft 6 other ends breaks off; The mandrel 1 at hollow shaft 6 two ends all is installed on the bearing 4, on the mandrel 1 at hollow shaft 6 two ends swivel joint 5 is installed all.
The center of mandrel 1 and core pipe 2 axially is provided with water channel 8, and the water channel 8 of core pipe 2 is communicated with the water channel 8 of bonded assembly mandrel 1; Swivel joint 5 is provided with water inlet 9, and water inlet 9 is communicated with the water channel 8 of mandrel 1; Be provided with inner chamber in the double helix sheet 3, the water channel 8 of mandrel 1 is communicated with the inner chamber of double helix sheet 3 through the apopore 7 that is arranged on the hollow shaft 6.
Cooling water expansion tank gets into water channel 8 through water inlet 9, and gets into the inner chamber of double helix sheet 3 through apopore 7, thereby accomplishes cooling-water cycle, reaches cooling purpose.
It is very simple and convenient that the utility model a kind of is exclusively used in its processing and fabricating of rotation cored screw axle of the quick-fried industry of the people, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of specification sheets, be the known technology of those skilled in the art.
