Abstract
The utility model discloses an air filter for vacuum sealed molding, which comprises an airtight tank, wherein an air outlet is disposed at the upper part of the tank, a dust adsorption liquid is disposed at the lower part of the tank, an air inlet is disposed on the tank, the intake pipe of the air inlet extends in the dust adsorption liquid, a dust adsorption liquid filling opening is disposed on the tank, a drain is disposed at the bottom of the tank, and a air filtration device is disposed at the upper part of the tank closed to the air outlet. The fine sand and dust sucked from sand box is filtered by the adsorption liquid and falls onto the bottom of the tank due to the adsorption by the adsorption liquid and the submergence by self-weight, and the settled fine sand and dust can be cleaned out by periodically opening the dust exhaust valve. The utility model has the advantages of simple structure and good dedusting effect; and can remarkably improve the work efficiency and service life of the vacuum pump.
Description
Technical field
The utility model relates to a kind of air filter, relates in particular to the air filter of dust in a kind of filtering air.
Background technology
Vacuum sealed molding is a kind of physics molding, and it utilizes plastic sheeting sealing sandbox, and relies on air in the vavuum pump extraction type, pressure differential is arranged inside and outside causing casting mold, makes the dry sand consolidation, to form the physics formative method of required die cavity.
When vavuum pump during suction air, contains fine sand or dust in the air of suction in sandbox; In case enter in the vavuum pump, will influence the operate as normal of pump, reduce the service life of pump
Summary of the invention
Technical problem to be solved in the utility model provides a kind of fine sand in the vavuum pump suction air or vacuum sealed molding air filter of dust removed.
For achieving the above object, the technical solution of the utility model is: the vacuum sealed molding air filter, comprise airtight tank body, the top of described tank body is provided with the gas outlet, the bottom of described tank body is placed with the dust adsorption liquid, also be provided with air inlet on the described tank body, the air inlet pipe of described air inlet extend in the interior dust adsorption liquid of tank body, also be provided with dust adsorption liquid filling opening on the described tank body, the bottom of described tank body is provided with sewage draining exit, and described tank body top is provided with air filter near the position of gas outlet.
Owing to adopt technique scheme, suction comes in the sandbox fine sand and dust filter through adsorption liquid, and fine sand and dust are adsorbed liquid absorption and depend on deadweight to sink, and fall tank base, regularly open the dust discharge valve, fine sand and dust that removing sinks and; The utility model is simple in structure, good dedusting effect, operating efficiency and the service life that can improve vavuum pump greatly.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
The specific embodiment
As shown in drawings, the vacuum sealed molding air filter, comprise airtight tank body 1, the top of described tank body 1 is provided with gas outlet 4, the bottom of described tank body 1 is placed with dust adsorption liquid 7, also be provided with air inlet 3 on the described tank body, the air inlet pipe of described air inlet 3 extend in the interior dust adsorption liquid 7 of tank body, also be provided with dust adsorption liquid filling opening 5 on the described tank body 1, the bottom of described tank body 1 is provided with sewage draining exit 6, described tank body top is provided with air filter 9 near the position of gas outlet 4, and described air filter 9 is an air filter screen, and its effect is that air is carried out double purification.
For improving air and dust adsorption liquid and time of contact and area, the end of the air inlet pipe of described air inlet 3 is fixedly connected with distribution device 8; Described distribution device 8 is provided with the body of some qi-emitting holes 81 for the surface.Certainly, described distribution device 8 is provided with the discoid body of some qi-emitting holes 81 and hollow for the surface.
The dust adsorption liquid 7 that present embodiment adopts is a water.
