Abstract

The utility model provides a cooling sieve body, which is simple in structure and good in screening efficiency, can further screen sand, and simultaneously can play a cooling role. A mounting base is arranged at the bottom of the sieve body. The cooling sieve body is characterized in that a ventilating plate is arranged inside the sieve body, wherein a plurality of blast caps are uniformly distributed on the ventilating plate; a plurality of cooling water pipes are arranged inside the sieve body and correspond to an array above the ventilating plate; an intake pipe is arranged on the lateral wall of the sieve body; the front end of the ventilating plate is connected with screen cloth; a material outlet is arranged below the screen cloth; and a slag outlet is connected to one side of the screen cloth.

Description

Cooling sieve nest

Technical field

The utility model relates to the sand preparing machine of casting industry, is specially the cooling sieve nest of a kind of vibration.

Background technology

While adopting the mixed precoated sand processed of hot method, first first roughing sand is heated to equably roughing sand is heated to 120～150 ℃ equably, subsequently warmed-up roughing sand and hard resin are added in puddle mixer and are mixed, after resin fusing, remain on sand grains and envelope sand grains.Now in puddle mixer, half-finished precoated sand is easy loose bulk and bulk; conventionally can use vibratory sieve to the broken processing of sand process; yet can mix certain waste material in broken complete sand; affect into the quality of sand; now sand still has very high temperature; can not directly pack; need to carry out again cooling processing; again screening is set respectively, cooling device makes to have high input; operation is loaded down with trivial details; along with the raising of production requirement, for the quality requirement of finished sand, day by day improve, and existing screening plant screening effect is desirable not to the utmost.

Utility model content

For the problems referred to above, the utility model provides cooling sieve nest, and it is simple in structure, can carry out refinement screening to sand, and screening efficiency is good, can play cooling effect simultaneously.

Its technical scheme is such: the bottom of sieve nest is provided with mount pad, it is characterized in that: in described sieve nest, be provided with ventilative board, on described ventilative board, be evenly placed with some blast caps, in sieve nest, above corresponding described ventilative board, arrayed has some cooling water pipes, on the sidewall of sieve nest, be provided with blast pipe, the front end of described ventilative board is connected with screen cloth, and the below of described screen cloth is provided with discharging opening, and a side of described screen cloth is connected with slag notch.

It is further characterized in that: described ventilative board is obliquely installed, described cooling water pipe oblique arrangement, and the angle of inclination of described ventilative board is consistent with the angle of described cooling water pipe oblique arrangement;

On described sieve nest, top cover is installed, the two ends of top cover are respectively arranged with sand inlet and air outlet;

On the sidewall of the sieve nest of corresponding described ventilative board below, be provided with observation panel;

Described blast pipe cuts pipe for becoming.

The beneficial effects of the utility model are: sand contacts with cooling water pipe and carries out heat exchange from sand inlet enters sieve nest, the logical cold wind of the wind of import simultaneously carries out air-cooled to sand, sand tumbles on discharging screen cloth and sieves after cooling, the suitable sand of particle falls screen cloth and flows out from discharging opening, underproof waste material is discharged from slag notch, it is effectively separated waste material and qualified finished sand, guaranteed the quality of finished sand, it is simple in structure, can complete screening and cooling two functions simultaneously, cooling, screening efficiency good.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is described further.

See Fig. 1, Fig. 2, Fig. 3, the utility model comprises that sieve nest 1 bottom is provided with mount pad 2, in sieve nest 1, be provided with ventilative board 3, on ventilative board 3, be evenly placed with some blast caps 4, in sieve nest 1, corresponding ventilative board 3 top arrayed have some cooling water pipes 5, ventilative board 3 is obliquely installed, cooling water pipe 5 oblique arrangement, the angle of inclination of ventilative board 3 is consistent with the angle of cooling water pipe 5 oblique arrangement, on the sidewall of sieve nest 1 one end, be provided with blast pipe 6, blast pipe 6 cuts pipe for becoming, the front end of ventilative board 3 is connected with screen cloth 7, the below of screen cloth 7 is provided with discharging opening 8, one side of screen cloth 7 is connected with slag notch 9, on the sidewall of the sieve nest 1 that corresponding ventilative board 3 is transferred, be provided with observation panel 10.

Sand contacts and carries out heat exchange with cooling water pipe 5 after entering sieve nest 1, the logical cold wind of inlet tube 6 carries out air-cooled to sand simultaneously, sand tumbles on screen cloth 7 and sieves after cooling, the suitable sand of particle falls screen cloth 7 and flows out from discharging opening 8, and underproof waste material is discharged from slag notch 9, it is effectively separated waste material and qualified finished sand, guaranteed the quality of finished sand, it is simple in structure, can complete screening and cooling two functions simultaneously, cooling, screening efficiency good.
