Description
Technical field
The invention belongs to and be specially adapted for the cleaning of mold material or the machinery of process or equipment, particularly relate to a kind of resin sand reclaiming machine for waste sand.
Background technology
In world wide, reach more than 70% with the foundry goods that sand casting is produced.In general, often produce 1t castings, produce 1 ~ 1.3t antiquated sand, discarded a large amount of antiquated sand not only wastes resource, and causes great harm to environment.Casting mold is after cast, if irreversible change does not occur the binding agent in most of molding sand, as long as then remove impurity, through inhaling ash cooling and mixed system just can the original performance of recovery-type sand again, this processing mode is called reclamation of return sand, and the molding sand generally only having clay to bond could reuse.The sand mold chemically hardened and core (as the sand mold made with oil-sand, water-glass sand and various resin sand and core), the sclerous reaction of its binding agent is irreversible, in this case old sand can not reuse simply, failed for sand grain surface adhensive membrane is needed to remove, it is made substantially to recover the performance of roughing sand, this processing mode is called regenerating used, then adopts resin sand reclaiming machine for waste sand under normal circumstances.
Existing resin sand reclaiming machine for waste sand mainly comprises hopper and bobbing machine, bobbing machine is arranged on hopper, filter plate is provided with in hopper, resin sand old sand vibrates under the effect of bobbing machine, impinging one another, friction, the failed adhensive membrane in resin sand old sand surface is removed, thus volume reduces, by the rear performance namely recovering roughing sand from filter screen, can reuse after collection.Its shortcoming is: because existing resin sand reclaiming machine for waste sand only drives the motion of resin sand old sand by bobbing machine, the collision frequency between resin sand old sand is low, thus causes the inefficiency of regenerating device.
Summary of the invention
Object of the present invention is providing the resin sand reclaiming machine for waste sand that the collision frequency between a kind of resin sand old sand is high.
In order to achieve the above object, the invention provides a kind of resin sand reclaiming machine for waste sand, comprise hopper, filter screen and bobbing machine, described bobbing machine is arranged on hopper, wherein, agitating device is provided with in described hopper, described agitating device comprises motor and puddler, described puddler is fixed on the output shaft of motor, described filter screen is the filter screen of arc, and filter screen is positioned at the below of puddler, and the sidewall of described hopper is provided with air inlet and air outlet, air inlet, air outlet and hopper form vent passages, are provided with blower fan in described vent passages.
Principle of the present invention is: while bobbing machine vibration, motor drives puddler to stir the resin sand old sand in hopper, force between resin sand old sand and constantly collide, friction, thus the failed adhensive membrane in resin sand old sand surface is removed, then resin sand and dust leach from filter screen, and resin sand falls into the bottom of hopper, and dust is then discharged from air outlet.
Beneficial effect of the present invention is: agitating device has good stirring action to resin sand old sand, and the effective friction increasing each face of resin sand old sand, make resin sand old sand collide more fully and rub, favorable regeneration effect, operating efficiency is higher.Filter screen is the filter screen of arc, and when the resin sand old sand on filter screen is less, resin sand old sand then can be concentrated to the recess of filter screen, and resin sand old sand still can rub fully.
Further, described air inlet and air outlet are oppositely arranged, and air inlet and air outlet are all obliquely installed toward same oblique direction, and air inlet is positioned at the below of air outlet.When wind blows to air outlet from air inlet, from filter screen, filter the blowing force that the dust of dirt and resin sand are subject to wind, the gravity due to dust is greater than the gravity of resin sand, then can be blown farther, discharge from air outlet.Part, then can along the inclined-plane landing of air outlet in hopper by the resin sand of wind to air outlet.
Further, the sidewall of hopper bottom is also provided with chamber door, and chamber door is hinged on the sidewall of hopper.Open chamber door, the resin sand handled well in hopper can be taken out, easy to operate.
Further, described blower fan is air blast, and described air blast is located at air inlet, and wind blasts hopper from air inlet by air blast, and is blown out from air outlet by dust.
Further, described blower fan is air-introduced machine, and described air-introduced machine is located at air outlet place, and wind goes out from air outlet pressure-vaccum by air-introduced machine, and wind is then discharged together with dust from air outlet.
Accompanying drawing explanation
Fig. 1 is the structural representation of resin sand reclaiming machine for waste sand embodiment of the present invention;
Fig. 2 is the structural representation of agitating device in Fig. 1.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: hopper 1, filter screen 2, bobbing machine 3, puddler 4, air blast 5, servomotor 6.
Embodiment 1:
As Fig. 1, shown in Fig. 2, a kind of resin sand reclaiming machine for waste sand, comprise hopper 1, filter screen 2 and bobbing machine 3, the model of bobbing machine 3 is XL.10-BN-HW, quantity is two, be arranged on the two bottom sides of hopper 1 respectively, agitating device is provided with in hopper 1, agitating device comprises servomotor 6 and puddler 4, puddler 4 is fixed on the output shaft of servomotor 6, filter screen 2 is the filter screen of arc, filter screen 2 is positioned at the below of puddler 4, the bottom-hinged of hopper 1 has hopper door, the left side wall of hopper 1 is provided with air inlet, right side wall is provided with air outlet, air inlet and air outlet are all obliquely installed towards upper right side, the position of air inlet is lower than the position of air outlet, air blast 5 is installed in air inlet.
During specific works, in hopper 1, resin sand old sand is added from the top charging aperture of hopper 1, open servomotor 6, bobbing machine 3 and air blast 5, resin sand old sand is while vibration, resin sand old sand in puddler 4 pairs of hoppers 1 stirs, and forces between resin sand old sand and constantly collides, friction, thus the failed adhensive membrane in resin sand old sand surface is removed, then resin sand and dust leach from filter screen 2.The resin sand leached and dust are subject to the blowing force of wind, and the gravity due to dust is greater than the gravity of resin sand, then can be blown farther, discharge from air outlet.Part, then can along the inclined-plane landing of discharging opening to the bottom of hopper 1 by the resin sand of wind to air outlet.
Embodiment 2:
The difference of this programme and embodiment 1 is: cancel the air blast 5 that air inlet goes out, and install an air-introduced machine at air outlet place, gone out from air outlet pressure-vaccum by wind by air-introduced machine, wind is then discharged together with dust from air outlet.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
