Technical Field

The invention relates to the field of screening equipment, in particular to a discharging and overturning structure for screening flaky plate-shaped materials.

Background

In the garbage treatment, screening equipment such as a star-disk screen, a bar screen, a disk screen and the like is generally adopted in China. However, in practice, when processing garbage containing large flaky plate-like materials, the materials below the flaky plate-like materials are screened out through the screen body, and the fragment materials above the flaky plate-like materials follow the flaky plate-like materials to pass through the screen without being screened out. Although part of the fragment garbage materials can slide down to the screen body from the sheet-shaped plate-shaped materials in the rotation of the screen shaft to be screened, a large part of the fragment garbage materials are still taken away by the sheet-shaped plate-shaped materials to pass through the screen body, and the screening effect is not ideal.

Detailed Description

Referring to fig. 1 to 4, a discharging and turning structure for screening a sheet-shaped plate material includes a first screening module 10 and a second screening module 20, a height difference is formed between the first screening module 10 and the second screening module 20, the first screening module 10 is disposed obliquely, the second screening module 20 is disposed horizontally, and the sheet-shaped plate material falls from the first screening module 10 into the second screening module 20.

Between the first screen module 10 and the second screen module 20 a screen 30, the first screen module 10 being mounted on a frame 40.

First screening module 10 is including carrying sieve axle group 101, turning round sieve axle group 102 and upset sieve axle group 103, carries sieve axle group 101 to include a plurality of transport sieve axles 1011, and a plurality of transport sieve axles 1011 upwards arrange in proper order along the straight line slope, and a plurality of transport sieve axles 1011 highly increase progressively in proper order, and the height that turns round sieve axle group 102 is greater than the height of upset sieve axle group 103, forms a decurrent slope.

The rotational speed of the turning screen shaft set 103 is less than the rotational speed of the turning screen shaft set 102.

In this embodiment, the number of the sieve shafts of the turning sieve shaft group 102 is one, the number of the sieve shafts of the turning sieve shaft group 103 is one, and the configuration is a minimum unit capable of realizing a turning and discharging function, and in order to realize a discharging and turning situation with higher requirements, the numbers of the sieve shafts of the turning sieve shaft group 102 and the turning sieve shaft group 103 may be increased, for example, the number of the sieve shafts of the turning sieve shaft group 102 is two, and the number of the sieve shafts of the turning sieve shaft group 103 is two.

The second screening module 20 comprises a plurality of screen shafts 201.

First screening module 10 and second screening module 20 all adopt dish sieve structure to avoid the rubbish winding, the dish sieve has that dish installation angle is the same, two kinds of mounting means of deflection angle are installed to the dish. The sieve axle rotates under the drive of motor and transports forward in order to promote the rubbish material, and the dish forms the sieve mesh of requirement with the barrel and realizes the rubbish material screening at the transportation in-process.

The working principle of the invention is as follows:

when the garbage containing the sheet-like plate-like material 50 falls into the first screening module, a part of the broken garbage is located above the sheet-like plate-like material, and the other part is located below the sheet-like plate-like material. The material under the sheet-like plate is effectively screened after passing through the first screening module. Then the piece garbage 60 carried on the piece plate-shaped object falls into a second screening module, a downward slope is formed because the height of the turning sieve shaft group 102 is larger than the height of the turning sieve shaft group 103, so that the piece plate-shaped object has a certain turning angle before leaving the turning sieve shaft group, meanwhile, the rotating speed of the turning sieve shaft group 103 is smaller than the rotating speed of the turning sieve shaft group 102, so that the piece plate-shaped object has a certain turning angle, and the later garbage material with higher speed forms a forward pushing turning force for the piece plate-shaped object, so that the piece garbage material on the piece plate-shaped object is turned over in the blanking process, and is turned over to the piece plate-shaped object, and is effectively screened in the second screening module.

The invention can fully screen the upper and lower materials of the flaky plate-shaped material, ensure that the flaky plate-shaped material can turn over, and improve the screening efficiency of the garbage material.
