Description
Technical field
This utility model belongs to foundary industry sand preparing machine technical field, refers in particular to a kind of polygonal cylinder old sand crusberscreen.
Background technology
On foundry production line, regenerating used reuse is always up the important object of casting engineering technical staff's technical study. For the old sand that self-hardening sand casting technique produces, carry out regeneration. Usual way be adopt a kind of machinery dry reclamation technique unit, to obtain good technological process and rational technological condition of regeneration, reach under large-scale working condition, reduce production cost, economize on resources consume purpose.
But it is not in actual manufacturing process, device fabrication cost is high, and regeneration efficiency is low, broken thorough, decompose uneven, demoulding weak effect, it is impossible to meet and economize on resources, convert the requirement of economic benefit.
Summary of the invention
The purpose of this utility model is to provide the polygonal cylinder old sand crusberscreen of a kind of low cost, high benefit.
The purpose of this utility model is achieved in that polygonal cylinder old sand crusberscreen, including frame and protective cover, screening drum it is provided with in protective cover, wherein, described screening drum is hexagonal or octagon, it is internally provided with the Screening Network that shape is identical, when screening drum gyration, sand agglomerate is made to produce mutual collision, impact and stranding galls broken, and sieve, described protective cover side is provided with motor, opposite side is provided with bearing block, described motor is provided with power transmission shaft, described power transmission shaft traverse protective cover, and it is connected on described bearing block, described screening drum is socketed on described power transmission shaft, described screening drum side is provided with sand inlet, described sand inlet and described bearing block are in the same side, the bottom of described screening drum opposite side is provided with sand export, the longitudinal section of described screening drum is trapezoidal, and sand inlet end is higher than sand export end, old sand is facilitated to flow to sand export after screening.
Polygonal cylinder old sand crusberscreen mentioned above, wherein, is provided with decelerator, improves the torsion of motor output between described motor and power transmission shaft.
Polygonal cylinder old sand crusberscreen mentioned above, wherein, the end face of described protective cover is provided with dust removal port, it is simple to remove the dust in screening drum.
Polygonal cylinder old sand crusberscreen mentioned above, wherein, described protective cover is additionally provided with maintenance door and cleaning door, convenient maintenance and cleaning.
This utility model is prominent compared to existing technology and useful having the technical effect that can be widely applied to that the old sand of self-hardening sand casting technique and general clay-bonded sand casting technique is broken, screening and reuse, owing to the linear revolution of screening drum makes old sand spread rapidly and broken and screening, in screening drum turning course, sand agglomerate produces mutual collision, impact and stranding and galls broken, and sieve, continue collision without broken sand lump, rub mill with the hands, until crushing and screening, make the granularity of sand reach to crush, uniformly, the purpose of regeneration.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view schematic diagram of Fig. 1;
In figure: 10-frame, 11-protective cover, 12-screening drum, 13-Screening Network, 14-motor, 15-bearing block, 16-power transmission shaft, 17-sand inlet, 18-sand export, 19-decelerator, 20-dust removal port, 21-overhauls door, 22-cleaning door.
Detailed description of the invention
This utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 12: polygonal cylinder old sand crusberscreen, including frame 10 and protective cover 11, screening drum 12 it is provided with in protective cover 11, wherein, described screening drum 12 is hexagonal or octagon, it is internally provided with the identical Screening Network of shape 13, when screening drum 12 gyration, sand agglomerate is made to produce mutual collision, impact and stranding galls broken, and sieve, described protective cover 11 side is provided with motor 14, opposite side is provided with bearing block 15, described motor 14 is provided with power transmission shaft 16, it is provided with decelerator 19 between described motor 14 and power transmission shaft 16, the torsion of motor 14 output can be improved, described power transmission shaft 16 traverse protective cover 11, and it is connected on described bearing block 15, described screening drum 12 is socketed on described power transmission shaft 16, described screening drum 12 side is provided with sand inlet 17, described sand inlet 17 and described bearing block 15 are in the same side, the bottom of described screening drum 12 opposite side is provided with sand export 18, the longitudinal section of described screening drum 12 is trapezoidal, and sand inlet end is higher than sand export end.
Optimize further, the end face of described protective cover 11 is provided with dust removal port 20, it is simple to remove the dust in screening drum 12.
Optimize further, described protective cover 11 is additionally provided with maintenance door 21 and cleaning door 22, convenient maintenance and cleaning.
The old sand or the hot old sand agglomerate that are produced by foundry production by technological requirement join sand inlet 17, owing to the linear revolution of screening drum 12 makes material spread rapidly and broken and screening. Owing to screening drum 12 in octagon and does gyration, make sand agglomerate produce mutual collision, impact and stranding and gall broken, and sieved by Screening Network 13. Continue collision without broken sand lump, rub mill with the hands, until crushing and screening, make the granularity of sand reach to crush, uniformly, the purpose of regeneration, the old sand after screening, be directly discharged to outside machine by sand export 18.
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection domain of the present utility model according to this, therefore: all equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by within protection domain of the present utility model.
