Abstract

The utility model relates to a kind of sieve, is specially fluorescent material screening machine, comprises screen box and lower screen box, has sieve to connect between upper screen box and lower screen box; Upper screen box one end is feeding end, and feeding mouth is arranged at the top of feeding end, and the other end is discharge end, and discharge end has bulky grain to export, and sieve comprises inclined sieve and becomes with plane screen banks, and inclined sieve is positioned at the below of feeding end, and horizontal screen is positioned at below discharge end; Corresponding comprising at the bottom of inclined-plane and at the bottom of plane at the bottom of the case of lower screen box; Powder outlet is had at the bottom of plane; Outer wall at the bottom of plane connects vibrating device; At the bottom of inclined-plane, spring is installed.This fluorescent material screening machine, material time of staying on sieve is short, alleviates the load of inclined sieve, and when tumbling horizontal screen, material significantly reduces, so little to the load of whole sieve.Vibrating device mainly vibrates screening machine flat of bottom, and therefore power is little compared with the vibratory sieve power of full oscillatory type, and noise is little, and whole screening machine structure is simple, and separative efficiency is high.

Description

Fluorescent material screening machine

Technical field

The utility model relates to a kind of sieve, is specially fluorescent material screening machine.

Background technology

In fluorescent material screening process, because be wet screening, so high to the requirement of vibratory sieve, in the special sieve of fluorescent material, number of patent application is that 201020536293.2 " fluorescent powder wet sieving machines " provide a kind of vibratory sieve, under screen cloth, increase support net, to improve sieve intensity, bear moist fluorescent material weight.Although this technology can improve sieve holding capacity, meeting residual fluorescent powder between gripper shoe and sieve, and this design screen construction is complicated, adds sieve weight, and vibrating device power is large, and noise is also great.This sieve and be traditional vibratory sieve, screening efficiency is low.

Utility model content

For above-mentioned technical problem, the utility model provides the bolter that a kind of structure is simple, noise is little, efficiency is high.

Concrete technical scheme is:

Fluorescent material screening machine, comprises screen box and lower screen box, has sieve to connect between described upper screen box and lower screen box; Described upper screen box one end is feeding end, and feeding mouth is arranged at the top of feeding end, and the other end is discharge end, described discharge end has bulky grain to export, described sieve comprises inclined sieve and becomes with plane screen banks, and described inclined sieve is positioned at the below of feeding end, and described horizontal screen is positioned at below discharge end; Material is poured in upper screen box by feeding mouth, tumbles on horizontal screen from inclined sieve along inclined-plane; Corresponding comprising at the bottom of inclined-plane and at the bottom of plane at the bottom of the case of described lower screen box; Powder outlet is had at the bottom of described plane; Outer wall at the bottom of described plane connects vibrating device; At the bottom of described inclined-plane, spring is installed.

Described inclined sieve is also hinged with multiple baffle plate sieve, baffle plate sieves the direction tumbled at inclined sieve perpendicular to material, the two ends of described baffle plate sieve top edge are respectively by rope traction, steel wire rope connects spanner, and spanner upset controls the upset of rope traction baffle plate sieve and holds up or be fitted on inclined sieve.

The fluorescent material screening machine that the utility model provides, feeding mouth vibration is inviolent, do not need as traditional shaker disposable reinforced, but adopt lasting feed way, and material time of staying on sieve is short, alleviates the load of inclined sieve, when tumbling horizontal screen, material significantly reduces, so little to the load of whole sieve.Vibrating device mainly vibrates screening machine flat of bottom, and therefore power is little compared with the vibratory sieve power of full oscillatory type, and noise is little, and whole screening machine structure is simple, and separative efficiency is high.

Accompanying drawing explanation

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

Detailed description of the invention

Accompanying drawings detailed description of the invention of the present utility model, as shown in Figure 1, fluorescent material screening machine, comprises screen box 1 and lower screen box 2, has sieve to connect between described upper screen box 1 and lower screen box 2; Described upper screen box 1 one end is feeding end, feeding mouth 7 is arranged at the top of feeding end, the other end is discharge end, described discharge end has bulky grain to export 8, described sieve comprises inclined sieve 3 and horizontal screen 4 forms, described inclined sieve 3 is positioned at the below of feeding end, and described horizontal screen 4 is positioned at below discharge end; Material is poured in upper screen box 1 by feeding mouth 7, tumbles on horizontal screen 4 from inclined sieve 3 along inclined-plane;

Correspondingly at the bottom of the case of described lower screen box 2 to comprise at the bottom of inclined-plane at the bottom of 5 and plane 6; At the bottom of described plane, 6 have powder outlet 10; At the bottom of described plane, 6 outer walls connect vibrating device 11; At the bottom of described inclined-plane, 5 are provided with spring 12.

Material is poured in upper screen box 1 by feeding mouth 7, when inclined sieve 3 tumbles, first can carry out part screening, then tumble on horizontal screen 4 and be separated further under the vibration of vibrating device 11; Because material time of staying on sieve is short, alleviate the load of sieve, sieve does not need supporting mechanism, simplifies the structure, and isolated bulky grain is discharged from bulky grain outlet 8, large granular materials could be taken out without the need to opening upper screen box 1.The powder be separated to drop at the bottom of inclined-plane at the bottom of 5 and plane on 6, discharges from powder outlet 10.The vibrating device 11 of this device mainly vibrates screening machine flat of bottom, and therefore power is little compared with the vibratory sieve power of full oscillatory type, and noise is little, and whole screening machine structure is simple, and separative efficiency is high.

Described inclined sieve 3 is also hinged with multiple baffle plate sieve 13, the direction that baffle plate sieve 13 tumbles at inclined sieve 3 perpendicular to material, the two ends that described baffle plate sieves 13 top edges are drawn respectively by steel wire rope 14, steel wire rope 14 connects spanner 15, and spanner 15 upset control steel wire rope 14 draws baffle plate sieve 13 upset and holds up or be fitted on inclined sieve 3.

When baffle plate sieve 13 is holded up by steel wire rope 14 traction, regulating fender sieve 13 and the angle of inclined sieve 3, can change material and tumble speed on inclined sieve 3, and the time on the compass screen surface that adjustment rests on inclined sieve 3, fully sieve, baffle plate sieve 13 self also has sieve aperture.

Put down baffle plate sieve 13 to be fitted on inclined sieve 3, allow screening from large granular materials tumble down, until discharge from bulky grain outlet 8.
