Description

{Crushing Separator for Food Waste}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food waste sorting and sorting apparatus, and more particularly, to a food waste sorting apparatus for separating and separating vinyl from food waste collected separately while being collected in collection vinyl, will be.

Various measures such as composting, feed conversion, and fuel conversion have been attempted to prevent environmental pollution caused by increasing food waste and to recycle it, and development of devices for this purpose is actively being carried out. In order to recycle food waste, it is necessary to separate and remove foreign materials such as waste plastic, which is mixed with food waste and brought in together, and then finely crush food waste.

Currently, food waste has almost no metal (bone) or non-ferrous (stone, glass, plastic, etc.) because it is generalized to separate and collect garbage collected and collected in bulk bags or general plastic bags for separate collection. Therefore, there is no need to remove metal or non-ferrous materials, but it is necessary to separate and separate the food waste bag from the bag. Especially, the process of removing (separating, sorting) It is not easy.

(1) a device for removing vinyl from a mixture of plastic bags and food wastes separated in the previous process, (2) a device for simultaneously performing break-vinyl removal, and (3) a break-vinyl removal-crushing device Have been developed.

Examples of (1) and (2) are the registered patent 10-0418742 (see FIG. 1A) and the disclosed patent 2000-0063345 (see FIG. 1B), respectively. It can be applied only when there is no food waste grinding step or grinding is necessary.

③ The crushing machines that can be used as one device for breaking-vinyl removal-crushing are classified into rotary blade type and rotary hammer type.

The rotary blade type is a method of cutting food waste by tearing and breaking the vinyl containing food waste by a plurality of rotating blades (blades, shredding blades). The term 'blade, blade, or crushing blade' is used in the terminology, but it is not necessary that an actual blade is formed, and generally, it is a generally rectangular metal piece structure. The separated vinyl is floated while being blown by the wind generated by the blade rotating at a high speed or the wind power of the suction fan or the blower mounted on the outside, and the food waste is crushed to a small size and discharged downward. Japanese Patent Application Laid-Open Nos. 2002-0087622 and 10-0574063. According to this method, it is advantageous to crush food garbage to a desired size or less, but the broken vinyl is cut off small before it is discharged, and often passes through the screen together with the food garbage. Therefore, it is very inadequate to recycle the food waste in the downstream process, and there is a disadvantage that additional sorting equipment is required to supplement the waste.

In the rotating hammer type, a plurality of rotating paddles (hammer) hit the vinyl containing the food waste, breaks it, and the paddle repeatedly strikes and crushes the food waste. The manner in which waste vinyl and pulverized food wastes are discharged is the same as that of rotary blades. The vinyl is not finely crushed due to punching and punching of the vinyl by the paddle so that the separation can be performed well but the disposal of the food garbage is not smooth. Thus, in Patent Document 10-0639190, the end of the hammer is formed into a blade shape, and a fixed blade is provided on the inner wall so that a shearing force acts between the two blades (see FIG. However, there is a problem in that the apparatus is complicated and a great deal of attention must be paid to maintaining the state and spacing of the rotating and fixed blades.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the accompanying drawings. It should be understood, however, that the appended drawings illustrate only the contents and scope of technology of the present invention, and the technical scope of the present invention is not limited thereto. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the technical idea of the present invention based on these examples. Also, when reference numerals are used in the drawings, the drawings are used only for illustration purposes and are not intended to limit the elements.

Hereinafter, for convenience of explanation, a plastic bag in which food waste is contained is referred to as "food-vinyl", and a separated plastic bag which is broken and has almost no food waste therein is referred to as "waste vinyl".

Conventionally, a conventional stabbing food garbage grinding and separating machine includes an upper hopper into which food garbage ('food-vinyl') contained in vinyl is charged, a discharge port through which the separated vinyl is discharged, and a case 10 having a discharge opening, the case 10 is built so as to be rotatable in the longitudinal direction within the fixed to the rotating shaft 20 and the rotary shaft 20 is rotated by the drive means of the external mount and the axis of rotation And the striking plate 31 of the rotating body 30 which rotates at the time of operation is inserted into the striking plate 31. The striking plate 31 of the rotating body 30, And the waste food waste separated from the vinyl is continuously blown by the striking plate 31 of the rotating body 30, so that the food waste is separated from the food waste, After being pulverized, It shall be discharged to the outlet. The food waste grinding and separating machine has a plurality of discharge holes of a predetermined size for discharging only the food waste that has been pulverized to an appropriate size, and a screen 11 (a net, a perforated plate Etc.) are mounted.

In the present invention, a part of the rotating body 30 at least at the front end of the rotating body 30 includes a pair of blades 32 spaced apart from each other by a predetermined distance, and a pair of blades 32 at both ends of the pair of blades 32 And an open space 33 is formed between the two blades 32. The open / An example of the rotating body 30 having a simple structure is shown in Fig. 2, and a screen 11 provided adjacent to the lower portion of the rotating body 30 for filtering the pulverized food waste is also shown.

As shown in the drawing, the rotating body 30 applied to the present invention is open between a pair of spaced blades 32, and a striking plate 31 is attached to both ends thereof. The thickness of the blade 32 may be about 10 to 30 mm, which corresponds to the thickness of the rotary blade of the rotary blade type pulverizer in the art. With this feature, in the rotary body 30 of the present invention, the striking plate 31 functions as a normal rotary hammer, and the edge of the blade 32 functions as a normal rotary blade.

The rotating body 30 is fixedly mounted on the rotating shaft 20 and rotates together with the rotating shaft 20 at a high speed (for example, 6000 rpm). At this time, the charged food-vinyl first collides with the striking plate 31. Since the striking plate 31 is rotating at a high speed, the food-and-plastic is broken while receiving a considerably large impact, and at the same time, So that most of the food comes out of the vinyl (as if it were squeezed). The food waste and the waste vinyl thus separated are repelled by the centrifugal force in the direction away from the rotary shaft 20.

Since the separated waste vinyl is light and has a wide surface, it is floated by the strong centrifugal wind force generated by the high-speed rotation of the rotating body 30 and is discharged to the discharge port. At this time, a blower may be installed and discharged to a closed vinyl outlet by a forced wind force to prevent the injured waste vinyl from sinking or being caught in the rear end. Since the separated food waste is relatively small in size and large in density, it falls down to the bottom of the case 10, and repeatedly bumps into the edge of the blade 32 and the striking plate 31 of the rotating rotator 30 in this process And then crushed gradually and discharged through the outlet 11 through the screen 11. [

In the food-and-vinyl introduced by the food waste grinding separator to which the rotating body 30 according to the present invention is applied, the waste vinyl is neatly sorted and separated, and the separated food waste is crushed well to a desired size or less. That is, according to the present invention, waste vinyl separation and food garbage grinding can be simultaneously performed in one apparatus.

A blade may be formed at the front edge of rotation of the blade 32 so that pulverization of the food waste can be more effectively performed (not shown).

In addition, in order to increase the grinding efficiency of the food waste, the rotating body 30 may have an additional structure in the present invention. In other words, according to another embodiment of the present invention, the pair of blades 32 of the rotating body 30 is formed with an extended portion 34 with one side or both sides extending between both ends, And one or a plurality of shredding blades 36 having a predetermined thickness are rotatably supported on the fixed shaft 35 so as to be rotatable about the rotation axis 20 May be mounted. FIGS. 3 and 4B show one example in which the expanding portion 34 is formed on one side and the shredding blade 36 is one.

As shown in the figure, the shredding blade 36 is a metal piece having a predetermined thickness (for example, 10 to 30 mm) and has a shaft hole formed at one end thereof so as to be freely rotatably mounted on the fixed shaft 35.

When the rotating body 30 is rotated at a high speed by the external driving means in the apparatus according to the present invention, the centrifugal force expands the crushing blade 36 in the centrifugal direction (the center of the rotating shaft 20 to the crushing blade 36 A small rotating space having a radius as the center of the fixed shaft 35 and the outermost side of the crushing blade 36 is formed at the same time. In this case, the crushing effect in the three is generated by additionally crushing the food waste by rotation of the crushing blade 36 in addition to the edges of the striking plate 31 and the blade 32.

However, in order to further enhance the grinding effect by the shredding blade 36, the food waste not struck at the corners of the striking plate 31 and the blade 32 is concentrated in the 'small rotating space' of the shredding blade 36 It is good. For this purpose, in the present invention, it is preferable to form a guide plate 37 having a predetermined length between the two blades 32 behind the striking plate 31 of the rotating body 30 (see Figs. 4A and 4B).

The food waste grinding and separator according to the present invention having such a structure can be broken, pulsed vinyl separation, and food waste grinding in the following manner.

The food-vinyl charged through the hopper is broken while colliding with the striking plate 31 of the rotating body 30 rotating at high speed, and at the same time, the food waste and the waste vinyl are separated. Since the separated waste vinyl is light and has a wide surface, it floats while being blown by the strong wind generated by the high-speed rotation of the rotating body 30 and is discharged to the discharge port. The separated food waste collides at high speed with the striking plate 31 of the rotating body 30 and the edge of the blade 32 and the crushing blade 36 and is broken into smaller pieces. At the same time, the shredded pieces are repelled in the centrifugal force acting direction and collide with the inner wall of the case 10 or the screen 11, and then the striking plate 31 of the rotary body 30 and the blade 32 and the shattering edge 36 ), And the process of bouncing (hitting-bouncing-blowing) is repeated. In this process, the finely pulverized food waste passes through the screen 11 and is discharged to the lower outlet.

However, depending on the situation, it may happen that the unfractured tough fibers block the discharge hole of the screen 11. In order to prevent this, the gap between the 'large rotation space' and the screen 11 is finely spaced so that the distal end of the impact plate 31 scrapes the inside of the screen 11, or a separate scraper (not shown) May be intermittently provided to cut or cut off the substance blocking the discharge hole of the screen 11. [

On the other hand, depending on the type and composition of the food waste, there is a case that the food waste must be crushed more sufficiently. Therefore, in the food waste grinding and separator according to the present invention, it is preferable to mount a plurality of ordinary rotary hammers 38 or rotary blades on the rotary shaft 20 at the rear end of the case 10. The crushing and sorting machine according to the present invention includes a crushing-waste vinyl separating section at the front end where the rotating body 30 composed of the impact plate 31 and the edge-crushing blade 36 of the blade 32 is mounted, And a 'crushing zone' at the rear end where the rotary hammer 38 or the rotary blade is mounted. Of course, as described above, although the food waste is crushed in the break-waste vinyl separation section, it is intended to increase the efficiency of crushing food waste by placing a crushing section at the rear end. According to a preliminary test, it was preferable to make the shear 2/3 approximately the break-closed vinyl separation zone and the remaining 1/3 the crush zone. Figs. 5A to 5C are photographs of a production example of the food waste grinding separator according to the present invention.

According to such a structure, the efficiency of sorting the waste vinyl can be improved by breaking and separating the plastic bag containing the food waste in the split-waste vinyl separation section without cutting the waste small. The food waste is crushed by the rotating body 30 even in the split-waste vinyl separation section, but the coarse particles or the brittle fiber, which are not cut by the rotating body 30, . If necessary, the size of the discharge hole of the screen 11 under the split-waste vinyl separation section may be made slightly smaller (3 to 5 mm) than that of the crushing section.

In the crushing section, most of the food waste pushed from the break - waste vinyl separation section is finely crushed in the crushing section. The crushing zone can be provided with several blade housings made of thick iron structure with no hollows, so that durable tool steel or special steel blades can be mounted on both sides. As a result, the tough fiber and the bone texture are finely pulverized.

When the scraper is placed, it is preferable that the scraper support is not a clogged structure but a structure in which the medium is pierced, so that the unfractured fiber or texture is gradually moved to the crushing section in the break-closed vinyl separation section.
