Abstract
The invention provides a sand mulling and sieving device which comprises a bracket, a feeding hole, a spiral conveyer, a sand mulling machine and a vibrating sieve, wherein the sand mulling machine is composed of a barrel, a spiral stirring impeller, an impeller lifting structure and a discharge hole, wherein the barrel is of an inverted conical structure; the spiral stirring impeller is clung to the barrel from top to bottom; the discharge hole is formed in the bottom of the barrel; the vibrating sieve is composed of a sleeve, a semi-circular barrel structure sieve and a vibrating motor; the semi-circular barrel structure sieve stretches into the sleeve and is divided into a semi-arc sealed barrel plate and a straight plate sieve; one end of the vibrating sieve is connected to the discharge hole of the sand mulling machine on the bracket, and the other end of the vibrating sieve is provided with a discharge device; the angle between the vibrating sieve and a horizontal surface is kept within 30-45 degrees. The barrel of the sand mulling machine is of the inverted conical structure, the spiral stirring impeller is clung to the barrel from top to bottom and the impeller lifting structure is capable of fully and uniformly stirring; the vibrating sieve is independent in structural design is of a slope automatic-flow vibrating sieve form, and is capable of effectively obstructing unclean high-speed downflow sieving by use of a triangular bulge.
Description
Technical field
The present invention relates to casting technology field, more particularly, to a kind of mulling sand sifter.
Background technology
In casting process, mulling screening is particularly significant, is directly connected to the quality of foundry goods, if mixing is uneven, it is impossible to
Sticky clay slip is coated on sand grain surface the high power sand blender needed using there is rubbing to act on, can not possibly otherwise be obtained
To the second best in quality molding sand；There is large granular impurity in mixed raw material, during moulding, molding sand easily flows, and can cause the rigidity of casting mold
Not high, the dimensional accuracy of foundry goods is poor.
The content of the invention
Present invention aim at there is provided a kind of mulling sand sifter for going the removal of impurity, improve quality.
The object of the invention is achieved through the following technical solutions：The mulling sand sifter includes support, charging aperture, spiral
Conveyer, puddle mixer and reciprocating sieve, puddle mixer are made up of cylinder, agitating auger impeller, impeller lifting structure, discharging opening, cylinder
For inverted conical structure, agitating auger impeller is close to cylinder from top to bottom, and discharging opening is arranged on the bottom of cylinder；Reciprocating sieve
It is made up of sleeve, semicylindrical body structure sieve, vibration motor, semicylindrical body structure sieve is overall to be extend in sleeve, semicylindrical body knot
Structure screening closes cylinder plate and straight panel screen cloth for semi arch；Reciprocating sieve one end is connected to the discharging opening of puddle mixer on support, reciprocating sieve
The other end is drawing mechanism；Reciprocating sieve is kept for 30 ° -45 ° with horizontal plane angle；Straight panel screen cloth arranges multiple triangle projections；Vibrations
Sieve drawing mechanism is divided into waste port and finished product material mouth.
Present invention has the advantages that：The cylinder of puddle mixer is inverted conical structure, and agitating auger impeller is from top to bottom
It is close to cylinder inboard wall, impeller lifting structure can be stirred；The structure independent design of vibrosieve, is shaken using gradient gravity flow
Sieve form, with triangle projection is inverted, effectively intercepts rapidly dirty sub-sieve unclean；Screw conveyer can be effective in addition
Ground control transporting velocity.
