Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a breakable object processing device for crushing various breakable objects such as unnecessary ceramics and glass articles, and particularly relates to a breakable object processing device for crushing various breakable objects such as unnecessary ceramics and glass articles. First, the present invention relates to a breakables processing device that crushes various types of empty glass bottles in large quantities to reduce waste storage space and also enables reuse as recycled resources.

(Prior technology) Conventionally, as a waste treatment device for fragile items,
There is a device disclosed in No. 44895. It shatters breakables such as glass and ceramics by striking with a rotating striking plate. In this device, the rotary impact plate must be rotated in a closed system because the pieces smashed by the rotating impact plate will scatter, which is dangerous. Therefore, it is a repetitive task to open and throw in the fragile waste, close the lid, rotate the rotary striking plate, stop the rotation, open the lid, and throw in the waste again, which cannot be done continuously. Furthermore, when processing glass waste, it is crushed until it becomes a powder by being hit by a high-speed rotating striking plate, and if it contains metal pieces and other filth, it is difficult to sort it and it cannot be reused as cullet.

(Problems to be Solved by the Present Invention) In an attempt to solve these problems, a crushing type device was considered.

By the way, in general, fragile items range from large to small. For example, taking glass bottles as an example, there are a wide variety of bottles, from 1-sho bottles to drip bottles, and even bottles as large as drink bottles. If an attempt is made to crush all of this waste with one device, a situation will arise in which some bottles, large or small, will not be crushed. For example, a breakable material processing device is used that has a plurality of rotary blades that rotate around a common rotation axis and have a series of blade elements on the outer periphery, and a wall that is spaced apart from the rotary blades. Consider the case of crushing waste. In this case, the bottle is crushed by being caught between the rotary blade and the wall, but in order to bite into a large bottle, the series of blade elements must have a tall shape. However, in the case of a rotary blade having such a shape, small bottles will fit between the valley between the wall and the blade element, and the small bottles will come out of the breakables processing device as they are without any crushing force acting on them. Conversely, in the case of a rotary blade with a series of short blade elements, small bottles can be sufficiently crushed, but large bottles cannot be caught between the rotary blade and the wall and are still crushed. Can not do it.

(Object of the Invention) An object of the present invention is to solve the above-mentioned problems and provide a breakables processing device that can crush large and small bottles at the same time.

(Means for Solving the Problems) In order to achieve the above object, the breakable object processing apparatus of the present invention has the following configuration. That is, a plurality of rotary blades 1 having alternating tall blade elements and short blade elements on their outer peripheries and a plurality of rotary blades 2 having tall blade elements on their outer peripheries rotate around one rotation axis. They are arranged in parallel so that they rotate around the center. A wall body is arranged in a direction perpendicular to the planes of the two types of rotary blades and at an appropriate interval between the tips of the blade elements to supply and crush breakables.

(Function) The reason why large and small breakables can be simultaneously crushed by using two types of rotary blades in the breakable object processing apparatus of the present invention can be considered as follows. In other words, the rotary blade has a long blade element that alternately has two types of blade elements, a series of tall blade elements and a short blade element, on its outer periphery, and a series of tall blade elements that have only a series of tall blade elements on its outer periphery. The tall blade element of the rotary blade in the section acts to trap a large bottle between the rotary blade and the wall. A large bottle is crushed by the compressive force between both the tall and short blade elements of the two rotating blades and the wall. Of course, the sharp edges of the elements make it easier to crush.
On the other hand, small bottles have no problem with being bitten, and the crushing is mainly performed by a rotating blade having two types of blade elements: a series of tall blade elements and a short blade element.

(Example) Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a side sectional view of the breakables processing apparatus of this embodiment. In the figure, this breakables processing device consists of a storage frame 16, a belt conveyor 7 driven by a conveyor geared motor 6, a wall 3, a fixed blade 4 fixed to the wall 3 with a hard bolt 14, and a hard bolt 15. It has a fixed fixed blade 5, an inclined surface 11, an outlet 12, and an internal cleaning pipe 13. Further, among the rotary blades that are rotated by a geared motor 8 for rotary blades via a rotating shaft 10, a rotary blade 1 is shown in which a tall blade element 1' and a short blade element 1'' are arranged on the outer periphery. ing.

In FIG. 1, the rotary blade 1 has six tall blade elements 1' and six short blade elements 1'' arranged alternately around its outer circumference.Tall blade elements 1' For example, the height from the center of rotation is about 15 cm, and the height of the short blade element 1" from the center of rotation is about 15 cm, for example.
13.6cm, and the valley position is approximately 10cm from the center of rotation.
(However, the present invention is not necessarily limited to such numerical values, and the optimum value should be determined in consideration of the range of dimensions of the various fragile objects.)

A rotary blade 2 consisting solely of a series of tall blade elements 2' is shown in FIG.

The blade elements of the rotary blades 1 and 2 form a triangular shape (however, in the present invention, the shape is not necessarily limited to this; for example, the lengths of the two outer sides are triangular, like the teeth of a saw). It may have a different shape, and the tip may not necessarily be sharp as shown in the figure). Each of the tall blade elements in rotary blades 1 and 2 has a sharp edge on the side that bites into breakables,
The opposite side is not pointed (however, in the present invention, both sides may be pointed). Rotary blade 1
Each of the shorter blade elements 1'' is sharp on both sides.It is possible to have only one sharp edge, but it is preferable to have both edges sharp in terms of crushing efficiency.

FIG. 2 is a partially cutaway front sectional view of the breakable material processing apparatus of this embodiment as seen from the right side of FIG. The blade elements 1' and 2' are arranged in parallel with an interval of 15 mm and have tall blade tips 1' and 2'. The number of two types of rotary blades 1 and 2 is 1.
There are four blades, and three rotary blades 2. The two types of rotary blades 1 and 2 are arranged in an alternating order.

In this embodiment, as described above, the thickness and number of rotary blades 1 and 2,
The distance between them is not limited to the above value, and furthermore, the tips of the tall blade elements 1' and 2' do not necessarily have to be exactly aligned. Also, the arrangement order of the two types of rotary blades 1 and 2 is
The order is not necessarily limited to alternating, for example, rotary blade 1, rotary blade 1, rotary blade 2, rotary blade 2, rotary blade 1, rotary blade 1... or rotary blade 1, rotary blade 2, rotary blade 2. , rotary blade 1, rotary blade 2, rotary blade 2...
A variety of array dimensions are possible, such as. This should be determined by taking into account the shape and size range of the target breakable object, the ease with which it can be bitten, etc.

In FIG. 1, the wall 3 is arranged obliquely. The preferred slope may be determined by taking into account the shape of the target breakable object and determining the appropriate flow (in some cases, it may be approximately perpendicular). Rotary blades 1 and 2 and wall 3
In this embodiment, for example, the shortest distance from the center of rotation of the rotary blades 1 and 2 is about 17 cm (however, the present invention is not limited to this, and the distance between the (It should be determined to be optimal depending on the shape and size range, the shape of the wall, the shape of the rotary blade, etc.)

In this embodiment, the wall 3 has a plate shape with a certain slope. However, in the present invention,
For example, the curved surface may have a slope that becomes gentler as it goes downward, or it may bend from a certain position and have a different slope.

On the wall 3, two rows of fixed blades 4 are attached to hard bolts 14.
It is fixed by. In the upper row, this fixed blade is shaped like a horizontally long triangular prism, and has, for example, six hard bolts arranged in parallel.
4, and in the lower row, similar ones are, for example, 5 hard bolts 1 arranged in parallel.
It is fixed at 4.

In this embodiment, the fixed blade 4 is attached to the wall 3 as described above.
However, in the present invention, it is not necessarily necessary to provide the fixed blade 4. Due to the compressive force between the rotating blades 1 and 2 and the wall, the fixed blade 4
This is because breakables can be crushed even without the fixed blade 4, but it is preferable to have the fixed blade 4 because crushing efficiency is improved and power can be saved. Furthermore, in the present invention, the shape and arrangement of the fixed blades 4 are not limited to those described above. Even if a plurality of long blades are arranged in the vertical direction instead of arranging them in the horizontal direction, the action of the sharp cutting edges facilitates crushing. The long blade may be textured, for example like a saw blade. Furthermore, a plurality of fixed blades 4, such as a conical, triangular pyramid, or quadrangular pyramid shape, are arranged horizontally and/or vertically, preferably in a plurality, for example, 3 to 3.
It may be 20 pieces lined up.

In this embodiment, six fixed blades 5 projecting substantially horizontally from the wall 3 and the rotary blades 1 and 2 are fixed to the lower part of the wall 3 and the rotary blades 1 and 2 by hard bolts 15. As a result, objects caught between the blade elements are also crushed, and the crushing efficiency is increased, and in particular, small bottles and the like can be crushed reliably and sufficiently.

As described above, in this embodiment, the fixed blade 5 is provided, but the fixed blade 5 is not absolutely necessary in the present invention. However, it is preferable to have the fixed blade 5. Further, the fixed blade 5 is not limited to the one shown in FIG. 1, but may be one having unevenness like a saw blade, for example. The number of fixed blades 5 is not limited to 6, but may be 3 to 10, for example, and should be determined in consideration of the number of rotary blades 1 and 2, etc.

Next, in the case of the embodiment of the breakable object processing apparatus of the present invention shown in the drawings, we will follow the process using a glass bottle as an example.

Various empty glass bottles are placed on a belt conveyor 7 driven by a geared motor 6 for the conveyor. Empty bottles transported to belt conveyor 7 are placed in input port 1
The rotary blades 1 and 2 roll down from the rotary blade 7 along the wall 3 and are rotated by the rotary blade geared motor 8 via the rotary blade chain 9 and the rotating shaft 10 at, for example, about 6 rotations per minute. It is caught between the wall 3 and crushed with the assistance of fixed blades 4 and 5 fixed to the wall 3. The crushed glass pieces pass through the gaps between the fixed blades 5 or fall from the tips of the fixed blades 5, slide down the inclined surface 11, and exit the apparatus through the outlet 12. Note that an internal cleaning pipe 13 is provided in the apparatus, so that the inside of the apparatus contaminated with the contents remaining in the empty bottles can be cleaned by spraying.

(Effects) According to the breakables processing device of the present invention, the combination of its special rotating blades allows it to crush breakable wastes of mixed sizes at the same time, reducing the storage space for such wastes to about 1/3 to 1/6. Can be reduced. In particular, empty glass bottles and the like can be reused as cullet after being crushed. In this case, since the pieces are relatively large, even if metal pieces or other contaminants are mixed in, they can be easily sorted by passing them through a sorter, and there will be no problem in reusing them as cullet. Furthermore, the rotating speed of the rotary blade is relatively slow, which saves energy in terms of power.Furthermore, since fragments do not scatter, breakable items can be continuously fed into the device, making work easier. can also be made continuous. Furthermore, even if unbreakable metal cans, razors, and other wastes are mixed in with the waste, the rotary blade system of this device will not become clogged and become inoperable.
