Abstract

The utility model discloses a multilayer vibration screen, comprising a support, wherein the support is connected with a vibration screen body via a vibration spring; a vibration motor is fixed below the vibration screen body; a charge port is arranged above the vibration screen body; a first screen plate and a second screen plate are arranged above and below in the vibration screen body below the outlet of the charge port; a first discharge port is connected to the tail end of the first screen plate; a second discharge port is connected to the tail end of the second screen plate; and a third discharge port is connected to the vibration screen body below the tail end of the second screen plate. The multilayer vibration screen disclosed by the utility model is used for generating vibration via the vibration motor, and screening sand mould broken blocks, binding materials and powdery silica sand mixed in a heat-insulated medium, i.e., silica sand, by virtue of the first screen plate and the second screen plate for reutilization; and the multilayer vibration screen is simple in structure and easy to realize, greatly increases the working efficiency, provides a guarantee on the subsequent product quality, decreases production cost, and increases enterprise benefits.

Description

A kind of multilayer vibratory sieve

Technical field

The utility model relates to a kind of vibratory sieve, relates in particular to a kind of multilayer vibratory sieve that is used to sieve the thermal insulation medium silica sand.

Background technology

At present, the thermal insulation medium silica sand is mixed with sand mold fragment and binding material mostly when the product outlet, and manufacturing enterprise adopts artificial selection mostly when production and processing; Inefficiency; Choose unonly, in the subsequent production process of product, bring inconvenience, also influence the heat insulation effect of product simultaneously.Owing to mixing a large amount of Powdered silica sands in the thermal insulation medium silica sand, can't it be separated once more by hand and utilize, improved production cost greatly.

The utility model content

The purpose of the utility model provides a kind of multilayer vibratory sieve, can the sand mold fragment and the binding material that mix in the thermal insulation medium silica sand sieved out, pulverous silica sand is separated carried out the secondary recovery use simultaneously, increases work efficiency, and reduces production costs.

The utility model adopts following technical proposals:

A kind of multilayer vibratory sieve comprises support, and support connects the vibration sieve nest through vibrating spring; Vibration sieve nest below is fixed with vibrating motor; Vibration sieve nest top is provided with charge door, is arranged with first sieve plate and second sieve plate on the vibration sieve nest of charge door outlet below is interior, and the tail end of first sieve plate is connected with first discharging opening; The tail end of second sieve plate is connected with second discharging opening, and the vibration sieve nest of second sieve plate tail end below is connected with the 3rd discharging opening.

The sieve diameter of described first sieve plate is greater than the sieve diameter of second sieve plate.

Both sides, described vibration sieve nest below all are fixed with vibrating motor.

Described support both sides connect the vibration sieve nest through two vibrating springs respectively.

The utility model produces vibration through vibrating motor; Utilize first sieve plate and second sieve plate that the sand mold fragment that mixes in the thermal insulation medium silica sand, binding material and pulverous silica sand are sieved out once more and utilize, simple in structure, be easy to realize; Not only greatly increase work efficiency; For the subsequent product quality provides assurance, and reduce production cost, increased the performance of enterprises.

Description of drawings

Fig. 1 is the structural representation of the utility model.

The specific embodiment

As shown in Figure 1; The utility model comprises support 1, and support 1 both sides connect vibration sieve nest 3 through two vibrating springs 2 respectively, and vibration both sides, sieve nest 3 below all are fixed with vibrating motor 4; Vibration sieve nest 3 tops are provided with charge door 5; Be arranged with the sieve diameter of the sieve diameter of first sieve plate 6 and second sieve plate, 10, the first sieve plates 6 greater than second sieve plate 10 in the vibration sieve nest 3 of charge door 5 outlet belows, the tail end of first sieve plate 6 is connected with first discharging opening 7; The vibration sieve nest 3 that the tail end of second sieve plate 10 is connected with second discharging opening, 8, the second sieve plates, 10 tail ends below is connected with the 3rd discharging opening 9.During use; The staff will be mixed with the thermal insulation medium silica sand of sand mold fragment and binding material and pour charge door 5 into; The thermal insulation medium silica sand that is mixed with sand mold fragment and binding material sieves through first sieve plate 6 and second sieve plate 10 under the effect of vibrating motor 4 and vibrating spring 2 successively; The sand mold fragment that thermal insulation medium silica sand inner volume is bigger is discharged from first discharging opening 7 that first sieve plate, 6 tail ends are connected with binding material; The less silica sand of thermal insulation medium silica sand inner volume is connected with second discharging opening 8 from the tail end of second sieve plate 10 and discharges, and Powdered silica sand is discharged from the 3rd discharging opening 9.
