Description

[0001] The present invention relates to a dual crushing type foreign substance removing apparatus,

More particularly, the present invention relates to a dual crushing type foreign substance removing apparatus, and more particularly, to a dual crushing type foreign substance removing apparatus, which is capable of firstly blowing waste falling from the top down to fuel the garbage or household waste, And removing the foreign matter and moisture from the wastes by a blade rotating at a high speed, thereby improving the fueling efficiency of the wastes.

Generally, the amount of various garbage (hereinafter referred to as "waste") is increasing with the development of the industrial society and the domestic culture, and various countermeasures for the treatment of increasing garbage have been studied variously, It is technically very difficult to treat it as a method of incineration using marine dumping, landfill, recycling or incinerator, thereby causing urban pollution, marine pollution, soil pollution, air pollution and water pollution.

To solve this problem, technologies such as producing alternative fuels such as SRF and RDF using waste are being developed.

However, landfilled wastes include ash, such as gravel, stones, and fine particles, and much moisture. In particular, if the illegal landfill waste is separately sorted in unsanitary landfills, sanitary landfills, and residential land development, It contains moisture, which makes difficulty in post-treatment.

Therefore, the conventional technology of disposal of the landfill waste is a pre-treatment process for removing foreign matters contained in the waste before the fuel is produced using the waste.

An example of a technique for solving such a problem is disclosed in Document 1 below.

Patent Document 1 (Japanese Patent Application Laid-Open No. H09-3258) discloses a vacuum cleaner comprising a housing having an inlet formed at one side thereof with an inlet for receiving waste, an outlet formed at the other side thereof, an upper side closed with a lid, A pair of wings are installed on the outer periphery of the rotary shaft in a direction symmetrical with respect to the rotation axis, and the wastes are blown off from the wastes to be introduced while the wastes are spread and a certain amount is supplied blade; A hitting portion provided at the rear of the blade inside the housing and provided with a plurality of hammers along an outer periphery of the rotary shaft to break the waste supplied from the blade by high speed rotation to break up and separate foreign matter; A rotating drum in the form of a net is connected to the outlet of the housing, and a spiral part for transferring the waste is formed on the inner wall of the rotary drum. The waste is crushed from the hitting part, And a drying unit for drying the waste by the wind generated by the high speed rotation of the striking unit. Particularly, the waste can be blown by a striking hammer to separate the foreign matter from the waste and then dried, so that it can be directly used for fuel.

However, in the conventional art as described above, it is necessary to discharge foreign substances or stones, which have been accumulated on the inner bottom of the housing, to be discharged to the outside, which is inconvenient and inconvenient for the work of discharging foreign matter or stones, There is a problem that the efficiency of separation is low due to irregular particles of the waste.

A foreign matter discharge port 13 is formed at one side of the lower portion of the main body 1 so as to discharge the foreign matter and moisture separated from the waste and discharged to the outside by the foreign matter discharging portion 6. [

The body 1 is provided with a plurality of foreign substance separating portions and a screen, respectively. However, the present invention is not limited thereto.

The first foreign material separating part 2 is installed on the upper part of the inside of the main body 1 and rotates at a high speed so as to hit the waste introduced through the charging port 11 to separate foreign matter and moisture contained in the waste.

The first foreign matter separation unit 2 includes a rotation shaft 21 rotated by a motor provided outside the main body 1 and a plurality of support plates 21, (22), and a plurality of hammers (23) detachably installed around the support plate (22).

The rotating shaft 21 is installed in the main body 1 in a horizontal direction and a ball bearing 211 and a bearing housing 212 are installed at both ends thereof. A belt pulley 213 for transmitting a driving force of a motor (not shown) is installed at one end of the rotating shaft 21, and a motor for supplying power to the rotating shaft 21 is rotatable in a forward / And a motor. Therefore, it is possible to extend the service life of the hammer 23 by adjusting the direction of rotation according to the degree of wear of the hammer 23.

The hammer 23 is detachably attached to the support plate 22 using bolts and nuts so that the hammer 23 can be easily replaced by adjusting the bolt and nut when the hammer 23 is worn or damaged You can.

The first foreign material separating unit 2 constructed as described above is capable of obtaining a high purity combustible material by blowing the waste falling vertically with a small amount of power and completely separating the foreign matter by the hitting force.

The first screen 3 has a cylindrical structure in which a plurality of through holes 31 are formed and is provided outside the first foreign material separating portion 2 and is separated from the foreign material separated by the first foreign material separating portion 2. [ , So that moisture is discharged.

The first screen 3 is formed with a first inlet 32 communicating with the inlet 11 of the main body 1 at an upper portion thereof and a second inlet 32 through which the first separated foreign matter and moisture- An outlet 33 is formed.

The second foreign material separating part 4 is disposed on the same vertical line as the first foreign material separating part 2 and rotates at a high speed to cut the waste falling from the first foreign material separating part 2, To separate foreign matter and moisture.

The second foreign matter separation unit 4 includes a rotation shaft 41 rotated by a motor provided outside the main body 1 and a plurality of support plates (42), and a plurality of blades (43) detachably installed around the support plate (42).
