Molding sand model all should not be continuing with, and again makes sand mo(u)ld after can not directly breaing up.According to statistics, often produce the foundry goods of a ton,
Big appointment produces the old sand of a ton.If these old sands can be carried out recycling, can not only solve to abandon old sand and be carried
The environmental problem come, moreover it is possible to save the cost such as fresh sand purchase commodity and traffic expense.Regenerating used can produce huge economic benefit
And social benefit.
Regenerating used refers to that old sand carries out machinery, physics or chemistry method to be processed, and removes on old sand surface long-pending
Poly-residue and inert membrane, make old sand return to the physical features close to fresh sand, to reach the mesh that fresh sand can be replaced to use
's.The mechanical method of reproduction of old sand is simple with its equipment, with low cost and be used widely.The regeneration of old sand machinery mainly by
The physical phenomenons such as mechanical force generation old sand grain and machinery collision between certain parts, old sand grain, friction so that old sand grain surface
Residue peels off.
The common device of old sand machinery regeneration has centrifugal regenerating device, vibrations crushing regenerator, spiral vibrating regenerating device, emery wheel
Regenerating device and adverse current rotor regenerator etc..Fig. 1 is centrifugal regenerating device fundamental diagram of the prior art, old sand entering from housing
Material mouth falls to blade, and sand is thrown to impact ring by the blade of high speed rotating.In the process, sand grains clashes into through three times with impact ring
Refraction, and phase mutual friction between sand grains, shock, make the inert membrane of sand grain surface rupture, reach the purpose of demoulding.This from
Although heart regenerating device simple in construction, with low cost, but demoulding is inefficient, many times in order to meet the demoulding of regenerating used
Demand, user needs to be used in series multiple centrifugal regenerating devices, adds the cost of regenerating used.
Utility model content
The technical problems to be solved in the utility model is that centrifugal regenerating device demoulding of the prior art is inefficient, it is impossible to full
The demoulding demand of foot regenerating used.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of centrifugal old-sand regenerating machine, bag
Include housing, rotating cylinder, rotor, blade, travelling gear and driving equipment；Rotating cylinder is positioned at housing, and rotating cylinder can be around its longitudinal center line
Rotate；Blade is installed on the upper end of rotor, and rotor is installed in rotating cylinder, and rotor can rotate around its longitudinal center line；Travelling gear
Being installed between rotating cylinder and rotor, travelling gear keeps rotating cylinder and rotor linkage；Device drives rotating cylinder or rotor is driven to rotate；Shell
The upper end of body offers charging aperture.
Further, the inwall of described rotating cylinder is provided with the floor at a plurality of sensing rotating cylinder center.
Further, ringwise and axial arranged along rotating cylinder, the inner ring cornice of floor is downward-sloping for described floor.Institute
Stating floor can also be elongated and along rotating cylinder circumferentially.
Beneficial effect: in (1) this utility model centrifugal old-sand regenerating machine utilizes rotating cylinder to replace conventional centrifugal regenerating device
Impact ring, rotating cylinder and rotor rotate the most in the opposite direction, add the relative velocity between old sand grain and rotating cylinder and old
Sand grains occurs to clash into and the number of times of friction in regenerating device, improves the efficiency of old sand demoulding.(2) this utility model is centrifugal old
Sand regenerator arranges travelling gear between rotating cylinder and rotor, and travelling gear keeps rotating cylinder and rotor linkage, it is only necessary to one is driven
Dynamic device drives rotating cylinder or rotor rotate the work that can realize regenerating device, simplify the structure of reclaiming machine for waste sand.(3) this practicality
Novel centrifugal type reclaiming machine for waste sand is provided with the floor at a plurality of sensing rotating cylinder center at the inwall of rotating cylinder, further increases old sand
Grain occurs with rotating cylinder to clash into and the number of times of friction in regenerating device, improves old sand demoulding efficiency.

Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
Embodiment 1
As shown in Figures 2 and 3, the present embodiment centrifugal old-sand regenerating machine includes housing 1, rotating cylinder 2, rotor 3, blade 4, passes
Moving gear 5 and driving equipment 6；
Rotating cylinder 2 is positioned at housing 1, and rotating cylinder 2 can rotate around its longitudinal center line；The inwall of rotating cylinder 2 is provided with floor 21, rib
Ringwise and axial arranged along rotating cylinder 2, the inner ring cornice of floor 21 is downward-sloping for plate 21
Blade 4 is installed on the upper end of rotor 3, and rotor 3 is installed in rotating cylinder 2, and rotor 3 can rotate around its longitudinal center line；
