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

A kind of mulling sand sifter
Technical field
The present invention relates to casting technology field, especially relate to a kind of mulling sand sifter.
Background technology
In casting process, mulling screening is very important, is directly connected to the quality of foundry goods, if mixing is uneven, the clay slip of thickness can not be coated on high power sand blender sand grain surface needing to use rubbing effect, otherwise the second best in quality molding sand can not be obtained; There is large granular impurity in mixed raw material, during moulding, molding sand easily flows, and the rigidity of casting mold can be caused not high, and the dimensional accuracy of foundry goods is poor.
Summary of the invention
The object of the invention there are provided a kind of mulling sand sifter removed impurity, improve quality.The object of the invention is achieved through the following technical solutions: this mulling sand sifter comprises support, charging aperture, screw conveyer, puddle mixer and reciprocating sieve, puddle mixer is made up of cylindrical shell, agitating auger impeller, impeller lifting structure, discharging opening, cylindrical shell is inverted conical structure, agitating auger impeller is close to cylindrical shell from top to bottom, and discharging opening is arranged on the bottom of cylindrical shell; Reciprocating sieve is sieved by sleeve, semicylindrical body structure, vibration motor is formed, and semicylindrical body structure sieve entirety extend in sleeve, and semicylindrical body Screening is that semi arch closes cylinder plate and straight plate screen cloth; Reciprocating sieve one end is connected to the discharging opening of puddle mixer on support, reciprocating sieve other end drawing mechanism; Reciprocating sieve and horizontal plane angle keep 30 °-45 °.
Described straight plate screen cloth arranges multiple triangle projection;
Described reciprocating sieve drawing mechanism is divided into waste material mouth and finished product material mouth.
Beneficial effect of the present invention is: the cylindrical shell of puddle mixer is inverted conical structure, and agitating auger impeller is close to cylinder inboard wall from top to bottom, and impeller lifting structure can stir; The structure independent design of vibratory sieve, employing gradient gravity flow riddler form, use and be inverted triangle projection, dirty sub-sieve is unclean rapidly in effective obstruct; Screw conveyer can control transporting velocity effectively in addition.
