That is, the lower knife means 40 is disposed at regular intervals in the longitudinal direction of the plurality of lower knife means 40 in the longitudinal direction on the rotary blade 120 is arranged at intervals of 90 degrees while being driven by the drive shaft 124 in the feeder 110.

At this time, as shown in Figures 3 and 4, the lower knife means 40, as with the upper knife means 20, the inclined portion 42 is integrally formed in a portion in contact with each other to increase the powder cutting efficiency. Is composed of a body 44 and a knife 46 of high hardness material is fixed to the inclined portion (42).

In addition, the knife 46 has a triangular cross section and is sharp in contact with the powdered coal, so that the powdered coal lump is easily cut and formed of a high hardness material and thus has abrasion resistance. Thus, the upper and lower knife means 20 The cutting of the powdered coal is prevented by the knife 26 and 46 of the knife 40.

3, the fixed plate 48 welded to the rotating blade 120 is integrally fixed to both side surfaces of the body 44 so that the lower knife means 40 on the rotating blade 120. The body 44 is to be firmly fixed vertically.

On the other hand, as shown in Figure 4, the lower knife means 40 is perpendicular to at least one of a total of four rotary blades 120 are fixed to the drive shaft 124 at intervals of 90 degrees in the feeder 110. In order to increase the cutting properties, the high humidity of the powdered coal charged into the feeder 110, the lower knife means 40 are installed on all four rotary blades 120, In accordance with it, it will be possible to install the lower knife means 40 on the two rotating blades 120 facing each other among the rotating blades 120.

At this time, it is important that the distance D between the body 44 of the lower knife means 40 and the body 24 of the upper knife means 20 is in the longitudinal direction of the bracket 10 irrespective of the gap width. To maintain a constant interval radially of the feeder 110, which is a cylindrical body.

And, as shown in Figure 6b, the lower knife means 40 can also adjust the number of installation or adjust the position, like the upper knife means 40, grooves concave in the rotary blade 120 ( 120b) and then through the holes (120a) formed therein, and then fixing the fixing end 50, the hole 50a is formed in the lower portion of the lower knife means 40, the fixing bolt 52 through the holes ) Is fixed to the fixing washer 54 and the nut 56. In the drawing, one lower knife means 40 is shown, but in fact, several pieces are installed in the longitudinal direction of the rotating blade 120.

At this time, the rotating blade 120 is preferable to increase the thickness than the conventional rotating blade 120 in consideration of processing the recessed groove (120b).

Therefore, since the humidity of the powdered coal charged into the feeder 110 is actually adjusted in advance and the mixing ratio of molasses is constant, the upper and lower knife means 20 as shown in FIG. 3 when the actual device 1 is used. 40 are preferably welded and fixed on the bracket 10 and the rotating blade 120, but if necessary, as shown in Figure 6, the upper and lower knife means 20, 40 are positioned It will also be possible to assemble it adjustable.

Referring to the operation of the present invention made in the above configuration in detail as follows, in the following the same configuration associated with the conventional coal briquette press 100 is represented by the same reference numerals.

As shown in Figure 3 to 5, in the feeder 110 of the coal briquette press apparatus 100 to prevent the pulverized coal 130 mixed with molasses in rotation to prevent the lump, if the pulverized coal is generated The powdered coal lump cutting device 1 of the coal briquette press apparatus of the present invention which can be pulverized to improve the productivity of coal briquette production is as follows.

First, when the powdered coal 130 mixed with molasses is loaded into the feeder 110 of the press apparatus 100, as shown in FIGS. 1 and 3, the upper driving motor 122 is driven and the driving shaft 124 is driven. 4 and a rotation blade 120 having a total of four installed at 90 ° intervals on the support block 123 at the lower end thereof are rotated as shown in FIG. 4.

Therefore, the molten molasses and the powdered coal 130 are mixed by the rotation of the rotating blade 120, and the processing groove 140 is supplied between the lower press rolls 140a and 140b through the outlet 112a of the feeder bottom 112. The coal briquettes 130 inserted into the ') are manufactured by the coal briquettes 130' which are pressed and injected into the Finex process.

At this time, as shown in Figure 3, a plurality of upper knife means 20 is fixed to the inner wall (110a) of the feeder 110 along the bracket 10, the predetermined interval (D) therebetween A plurality of lower knife means (40) installed vertically on the rotating blade 120 passes through the rotating blade 120 integrally.

Accordingly, as shown in FIGS. 3 and 4, the powdered coal passes between the triangular pyramid-shaped knives 26 and 46 provided on the body inclined portions 22 and 42 of the upper and lower knife means 20 and 40. As the coal dust is mixed with molasses, there is almost no generation of powdered coals, and at the same time, the powdered coals are continuously removed while cutting between the upper and lower knives 26 and 46 even if the powdered coals are generated.

As a result, according to the cutting device 1 of the present invention, while the generation of the coal lump itself is blocked in the feeder 110 of the coal briquette press 100, in particular, even if the coal lump is generated, it is immediately cut and removed. The blockage of the feeder outlet 112a by this is prevented in advance, which enables smooth supply of powdered coal for press operation of the coal briquettes, thereby improving the productivity of coal briquette operation.

On the other hand, as shown in Figures 6a and 6b, when the degree of powdered coal is increased as the humidity of the powdered coal is increased, the operator adjusts the position of the upper and lower knife means 20, 40 in the feeder 110 It is also possible to narrow the gap between the knife means bodies 24 and 44.

As described above, according to the coal briquette lump cutting device of the coal briquette press device of the present invention, when the coal briquettes are generated, the fine particles are minutely generated in the feeder while the knives are installed in the feeder of the press device for producing coal briquettes. By supplying the powdered coal to the press roll which cuts and forms the coal briquettes, it provides the effect of improving briquette operation productivity.

In addition, since the powdered coal lumps mixed with molasses are continuously cut to a certain size as knife means installed in the feeder of the press device, the rotation load of the rotating blade in the feeder and the driving shaft connected thereto are substantially blocked by generating the coal lumps substantially. The present invention provides a powdered coal lump cutting device of a coal briquette press device that provides an excellent effect of reducing equipment load such as to extend the life of the press device.                     

While the invention has been shown and described with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit or scope of the invention as set forth in the claims below. I would like to know that those who have knowledge of this can easily know.
