Description
Technical field：
The utility model is related to casting mold sand core manufacturing fields, relate generally to a kind of intake and exhaust structure for penetrating silo.
Background technology：
Sand shooting mechanism in the prior art mostly uses two schemes, and one of which scheme is using side action molds, top
Sand scheme is penetrated in portion, and the silo of penetrating of the program is arranged in mould upstream, penetrates the air inlet of silo, exhaust outlet is a mouth, there is
Dust after long-term work in molding sand blocks the problem of sand effect is penetrated in air inlet influence；Another kind penetrates sand using horizontal direction
Scheme, the program are made at work because its structure problem causes molding sand to have " angle of repose " and " into sand dead angle " penetrating in silo
At penetrating the defects of sand is insufficient, stability is bad.Use from a mouth air intake-exhaust structure, the time grown can because dust gather
Causing air intake-exhaust to block influences to penetrate sand, exhaust performance.
Utility model content：
The utility model aim is exactly to provide a kind of intake and exhaust structure for penetrating silo to make up the defect of prior art,
Penetrate silo ramp structure, more air inlets, the independent exhaust structure used solves the above problem.
The utility model is achieved through the following technical solutions：
A kind of intake and exhaust structure for penetrating silo, it is characterised in that：Include to penetrate silo, the bottom for penetrating silo is oblique cone
Shape, described penetrate on rear side of silo are provided with rear air inlet grille, are provided with inlet screens in the rear air inlet grille, the silo top of penetrating is leaned on
Front position is provided with exhaust lattice, and exhaust sieve is provided in the exhaust lattice.
Described penetrating on silo bottom bevel is provided with lower air inlet grille, and inlet screens are provided in the lower air inlet grille.
The inlet screens, exhaust sieve structure are identical, the fixed steel-wire screen of iron plate to be covered with hole or be ventilative
Bronze sintered body.
Position of the exhaust lattice on penetrating silo is that top is forward or in the ramp position for penetrating silo bottom tilted conical
It sets.
It has been respectively communicated with compressed air inlet pipe road on the rear air inlet grille, lower air inlet grille, has been connected on the exhaust lattice
There is gas exhaust piping, air valve is respectively equipped on the compressed air inlet pipe road and gas exhaust piping.
Its principle is：The bottom for penetrating silo is tilted conical structure, and structure, which can guarantee to penetrate, does not have angle of repose in silo
With into sand dead angle, flowed under the effect of gravity to penetrating the directions Sha Kou after molding sand enters tank body, when penetrating sand from lower air inlet grille and after
Molding sand can be floated to get up to inject mold again by air inlet grille air inlet in chronological order；Individually from when rear air inlet grille air inlet because penetrate
There is no angle of repose in silo and into sand dead angle, it is also highly desirable to penetrate sand effect.And the advantage of the air inlet grille structure used also resides in
Air inlet and lower air inlet, for a long time using that can keep clear, keep stable performance only by clean compressed air afterwards.
The independent exhaust lattice structure used is in position convenient for disassembly and assembly, if working long hours causes exhaust lattice blocking can
It is repaired with convenient cleaning, is unable to if on-call maintenance also be that the residual voltage penetrated in silo after penetrating sand is arranged endless, be moved back penetrating silo
When back residual voltage from penetrate sand mouth discharge can take out of some molding sand fall into recycling bucket, do not influence to penetrate sand effect and site environment.
The utility model has the advantages that：
The structure design of the utility model is reasonable, and structure, which can guarantee to penetrate in silo, not to be had angle of repose and into sand dead angle, use
The structure that air inlet grille and lower air inlet grille combine afterwards can float molding sand from lower air inlet grille and the air inlet in chronological order of rear air inlet grille
It moves up and injects mold again, while for a long time using that can keep clear, keeping stable performance；And the independent exhaust lattice used
Structure is in position convenient for disassembly and assembly, and repair can be easily cleared up if working long hours and leading to be vented lattice blocking.
Description of the drawings：
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode：
Referring to attached drawing.
A kind of intake and exhaust structure for penetrating silo includes to penetrate silo 1, and the bottom for penetrating silo 1 is tilted conical, described to penetrate
The rear side of silo 1 is provided with rear air inlet grille 2, and inlet screens are provided in the rear air inlet grille 2, and anteposition is leaned on 1 top of silo of penetrating
It installs and is equipped with exhaust lattice 3, exhaust sieve is provided in the exhaust lattice 3.
Described penetrating on 1 bottom bevel of silo is provided with lower air inlet grille 4, and inlet screens are provided in the lower air inlet grille 4.
The inlet screens, exhaust sieve structure are identical, the fixed steel-wire screen of iron plate to be covered with hole or be ventilative
Bronze sintered body.
Position of the exhaust lattice 3 on penetrating silo 1 is that top is forward or in the ramp for penetrating 1 bottom tilted conical of silo
Position.
It is respectively communicated with compressed air inlet pipe road 5,6, the exhaust lattice 3 on the rear air inlet grille 2, lower air inlet grille 4
On be communicated with gas exhaust piping 7, air valve 8,9,10 is respectively equipped on the compressed air inlet pipe road 5,6 and gas exhaust piping 7.
It the compressed air inlet pipe road 5,6 can also the air inlet simultaneously in an air valve.
