Abstract
The invention discloses a filtering device. By arranging a feeding hopper of a special structure, introducing compressed air, adding a guide plate and arranging multiple layers of filtering core boards, filtering and reutilizing of reclaimed sand casting waste are improved, and the purposes of improving the filtering effect and protecting the environment are achieved.
Description
Technical field
The present invention relates to a kind of filter, especially for a kind of filter of the reclaimed sand system discharge thing filtered in casting technique.
Background technology
The Modeling Material overwhelming majority in sand casting adopts natural.Instantly environment form is increasingly serious, and sand regeneration techniques has become the technology that current foundry enterprise must be grasped.Thermal reclamation technology is the sand regeneration techniques that current regeneration rate is the highest, and the dedusting of thermal reclamation sand is carried out mainly through ventilation and dust removal mode.In the solid waste that current ventilation and dust removal mode is discharged, containing a large amount of reclaimed sand particles, these particle size distribution wider range, performance is consistent with ordinary hot method reclaimed sand, but limits due to current technology, cannot be utilized and be discharged into nature.
Summary of the invention
The object of the invention is to: a kind of filter is provided, the discarded object after casting model powder regeneration is filtered, effectively the thicker particulate matter in discarded object can be filtered out, be convenient to focus on or again utilize.
A kind of filter, comprises filter core and housing, and described housing includes hopper, compressed air inlet and particle outlet, and described filter core is arranged on the middle part of housing cavity room, and described housing central section bottom is provided with deflector near the position of filter core.
As preferably, the filtration central layer that described filter core is fixed on connecting plate by several layers of top is formed.
As preferably, described filtration central layer is according to the fineness being filtered thing arrangement from coarse to fine.
As preferably, described housing central section top and filter core connecting plate are provided with pilot hole, are connected by set bolt.
As preferably, the position corresponding with filter core, described housing central section bottom is provided with filtrate outlet.
As preferably, between described filter core bottom and housing bottom, leave gap.
As preferably, described material bin is the bucket-shaped structure that discharging opening width is less than feeding mouth width.
As preferably, the relative angle of described deflector and housing bottom is 15 degree.
Material bin adopts discharging opening to be less than the bucket-shaped structure of charging aperture, and object is the input being conveniently filtered material, simultaneously when down being dropped by material bin, forms the shape of similar waterfall, fully to contact with compressed air.Housing central section bottom is provided with deflector near the position of filter core simultaneously, is in order to better by compressed-air actuated one-way gas flow guiding filtration core direction, improves filter efficiency.When deflector and housing bottom relative angle are 15 degree, water conservancy diversion best results.Be filtered material by after one-way gas flow guiding filter core, filtered central layer according to its fineness by each layer filter and fall to the space between filter core bottom and housing, discharge from filtrate outlet subsequently, last unwanted particulate matter enters other external dust arresters by outlet, completes the whole filter process to being filtered thing.The filtration central layer of filter core can be changed according to the thickness being filtered material, only need install by arrangement mode from coarse to fine.Simultaneously can according to be filtered material the shape of concrete condition to material bin, filter central layer position and filter fineness degree and compressed-air actuated pressure adjusts, to reach optimum filtration effect.
Structure of the present invention is simple, is convenient to safeguard, good filtration effect, reaches the object to being filtered material and carrying out secondary utilization and protection of the environment.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of this filter housing;
Fig. 2 is the schematic diagram of this filter filter core;
Fig. 3 is the overall schematic after the assembling of this filter;
In figure, 1 is housing, and 2 is material bin, and 3 is compressed air inlet, and 4 is particle outlet, and 5 is deflector, and 6 is feeding mouth, and 7 is discharging opening, and 8 is filtrate outlet, and 9 is pilot hole, and 10 is connecting bolt, and 11 is connecting plate, and 12 for filtering central layer, and 13 is filter core.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the present invention is further illustrated.
Shown in figure 1 and Fig. 2, this filter housing 1 is provided with material bin 2, material bin 2 is the bucket-shaped structure that discharging opening 7 is less than feeding mouth 6, housing 1 is also provided with compressed air inlet 3 and particle outlet 4, deflector 5 is also provided with bottom housing 1, deflector 5 is 15 degree with the relative angle of housing bottom, filter core 13 is 4 layers and filters central layer 12, according to degree of filtration by 30 orders, 70 orders, 100 orders, the arrangement from coarse to fine of 140 order, be formed by connecting by connecting plate 11, connecting plate 11 be also provided with the connecting bolt 10 suitable with the pilot hole 9 on housing 1 top.
Before filtering, filter core 13 is arranged on and exports 8 corresponding positions with filtrate, space is left between bottom filter core 13 bottom and housing 1, connecting plate 11 is connected with the pilot hole of housing 1 by connecting bolt 10, compressed air inlet 3 external compressed air device, particle exports 4 other dust arresters external, arranges receiving system, complete the assembling of whole filter below filtrate outlet 8.
Blowing plant switch is opened after having assembled, pressure atmospheric pressure is set to 0.4Mpa, deflector 5 by compressed air one-way guide flow to filter core 13, thing will be filtered and be put into material bin 2, width due to discharging opening 7 is less than feeding mouth 6, being filtered when thing falls is similar waterfall shape, filter core 13 is involved in by compressed air, filter central layer 12 and will be filtered material filtration from coarse to fine, the material be filtered falls to bottom housing 1 immediately, discharge along with the space between bottom filter core 13 and housing 1 exports 8 with filtrate, particle remaining is after filtering expelled to other dust arresters with air-flow from particle outlet 4, to complete whole filtering process.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
