Fig. 17 is a diagram showing a shearing crusher according to a tenth embodiment of the present invention, (a) is a side view of a partial section, (b) is a longitudinal sectional view of the XVII-XVII section when the opening and closing door is closed, (c ) is a longitudinal sectional view when the opening and closing door is opened. This tenth embodiment is an example in which the throughput is doubled by using one shearing crusher. Also in the tenth embodiment, the same structure as that of the above-mentioned first embodiment is denoted by adding 270 to the reference numeral, and the detailed description thereof is omitted. In addition, in this tenth embodiment, the lower casing of the above-mentioned first embodiment is also formed on the main body of the crusher. In addition, description of the stirring member is omitted in the drawings.

As shown in the figure, the crusher main body 271 of the tenth embodiment is formed in the longitudinal direction in the axial direction, and an inlet 279 is provided at the upper center thereof. Furthermore, inside the crusher main body 271, two rotating shafts 272, 273 are arranged in parallel in a freely rotatable state. The cutting blade 277 is cut in the axial direction of these rotation shafts 272 and 273 .

In the tenth embodiment, the cutting blade 277 provided in the axial direction of the rotating shafts 272, 273 is provided with a relatively thick cutting blade 277A at the lower part of the inlet 279, and the cutting blade 277A is provided toward the discharge port 280 side at both ends. Cutting knife 277B made relatively thin. In this way, coarse crushing is performed by the cutter blade 277A at the lower part of the input port 279, and fine crushing is performed by the cutter blade 277B on the discharge port side O. Furthermore, in the tenth embodiment, the crushed object T input from the input port 279 is crushed while being transported in the biaxial direction (left and right directions in the figure) of the crusher main body 271, so the processing amount can be doubled.

Also in the tenth embodiment, the lower part of the crusher main body 271 has side surfaces of the inner wall bent toward the center of the lower part, and a discharge bag 292 having a rectangular cross-section is formed in the axial direction of the central part.

The discharge bag 292 is provided over the entire length of the crusher main body 271 in the axial direction. In this embodiment, as shown in FIG. 17( a ), the discharge bags 292 are divided into three parts in the axial direction from the center of the crusher main body 271, and the discharge bags 292 are installed on the bottom of the farthest position from the input port 279. Open and close door 293. The lower surface of the discharge bag 292 other than the position where the opening and closing door 293 is provided is closed. The position where the opening and closing door 293 is provided forms the discharge port 280 .

The opening and closing door 293 has a structure capable of realizing any opening and closing state from the closed state shown in FIG. 17( b ) to the open state shown in FIG. 17( c ). The opening and closing mechanism of the opening and closing door 293 is constituted by an opening and closing mechanism using a hydraulic cylinder and a hydraulic motor. In addition, when the opening and closing door 293 is provided at the position shown in the figure, the crushed objects T are crushed and discharged by all the cutting blades 277A, 277B provided in the axial direction, and therefore small crushed objects with the smallest crushed size can be discharged.

As shown by the 2-point lock line in Figure 17(a), when the opening and closing door 293 is set at the position closest to the input port 279, the residence time of the crushed object T becomes the shortest, and large-sized crushed objects can be discharged. . On the other hand, when the opening and closing door 293 is arranged between the position closest to the inlet 279 and the position farthest therefrom, the residence time of the crushed objects T is moderate, and crushed objects T of a medium size can be discharged. object. In this way, the longer the distance from the input port 279, the longer the residence time of the crushed objects T inside, and the more times of repeated crushing, the smaller the size of the crushed objects.

In this tenth embodiment, the discharge port 280 is formed in a structure that can be changed at three positions different from the central part, but the number of the discharge port 280 is not limited to three, as long as it is based on the size of the crusher main body 271 and What is necessary is just to set the discharge size of the crushed object T, etc.

According to the shearing type crusher 291 configured as above, the crushing size of the object T to be crushed can be easily changed by setting the position of the opening and closing door 293 as required. Furthermore, since the crushed object T thrown in from the central portion is conveyed to the left and right for crushing, the throughput can be doubled.

In addition, the operation of repeatedly crushing the object T to be crushed in the crusher main body 271 is the same as that of the above-mentioned first embodiment, and therefore detailed description thereof will be omitted.

In addition, when the discharge bag 292 of the tenth embodiment is mixed with foreign matter E such as metal in the object T to be crushed from the input opening 279 as in the fifth embodiment, it may be provided with a foreign matter bag for storing the foreign matter E. function of the bag.

In addition, in this tenth embodiment, it is formed into a left-right symmetrical structure with respect to the input port 279, but it is also possible to make the structures of the left and right cutting blades 277A, 277B different, or make the distance to the discharge position different, and form them with the same The crushed object T obtains a structure of crushed objects of different sizes. These combinations are determined according to the type of object T to be crushed, crushing conditions, and the like.

Eleventh Embodiment

Fig. 18 is a side view showing a shear crusher according to an eleventh embodiment of the invention of the present application. This embodiment is an example of a structure capable of changing the inclination angle of the main body of the crusher. In addition, this eleventh embodiment shows the structure for carrying out the following examples. In addition, in this figure, since the example which inclines the shearing type crusher 61 of the said 3rd Embodiment is shown, the code|symbol is used for the same structure, and the detailed description is abbreviate|omitted. Also in this eleventh embodiment, description of the agitation member is omitted in the drawings.

As shown in the figure, in the crusher main body 61, a rear support part 300 is provided on the lower part of the inlet side I, and a front part support part 301 is provided on the upper part of the discharge port side O. A support shaft 302 is provided on the rear support portion 300 , and the support shaft 302 is supported by a stand 303 . A front end of a jack 304 serving as a driving machine is pivotally supported on the front support portion 301 , and a rear end of the jack 304 is pivotally supported on a stand 303 .

According to the shearing crusher 305 configured in this way, the inclination angle of the crusher main body 61 can be changed by extending and contracting the jack 304 as a driving machine to raise and lower the outlet side O of the crusher main body 61 .

Therefore, the crushed object T input from the input port 69 is agitated in the crusher main body 61 while being sent to the discharge port side O due to the inclination, and is crushed multiple times, resulting in fine crushing.

Example

Fig. 19(a), (b) and (c) are graphs of experimental results of crushing soft waste plastics using the shearing crusher shown in Fig. 18 . In this experiment, crushing was performed in a 2-shaft shearing crusher under the following conditions, and the results are shown. Said condition is

Shredded objects T: soft waste plastics such as polypropylene sheets for large packaging, polyethylene films, container bags, etc.

The particle size of the crushed object T: about 90% of long-sized objects above 1m, about 10% of objects below 1m,

The thickness of the cutting knife: 75mm on the inlet side, 25mm on the outlet side,

Rotational speed control of the cutting knife: make the two shafts rotate alternately at high-speed forward rotation (about 35rpm) and low-speed forward rotation (about 15rpm) every 20 seconds.

As shown in (a), in the relationship between the inclination angle and the processing capacity, the processing capacity is increased by inclining the main body of the crusher, but there is no significant change when the inclination is more than about 8°. As shown in (b), in the relationship between the inclination angle and the average particle diameter, the particle diameter becomes larger by inclination. This is considered to be due to the increased flow velocity of the crushed objects. As shown in (c), in the relationship between the inclination angle and the processing capacity per unit power, the processing capacity per unit power is increased by inclination, but there is no significant change even if the inclination is about 8° to 10° or more.

From these facts, it can be said that the optimum inclination angle at which the average particle size can be reduced while maximizing the processing capacity and the processing capacity per unit power is increased is about 8°. In addition, by alternately performing high-speed normal rotation and low-speed normal rotation of both shafts, it is possible to obtain a cleaning effect in which the object T to be crushed does not adhere to between the cutting blades. Also, the inclination angle of about 8° includes a range of about 6° to 10° that does not change much.

speed control

Fig. 20(a) and (b) are time charts showing an example of rotational speed control of the rotating shaft in the shearing crusher according to the invention of the present application.

In the case of crushing the crushed object T thrown in from the inlet as described above with the cutting blades 7, 37, 67, 97, 127, 157, 187, 217, 247, 277, and performing multiple crushing while conveying horizontally , can not be provided with the scraper plate that is used for removing the broken object attached on the cutting knife on the side of the crusher main body 1, 31, 61, 91, 121, 151, 181, 211, 241, 271.

Therefore sometimes the crushed objects T attached to the cutting blades 7, 37, 67, 97, 127, 157, 187, 217, 247, 277 are not removed from the cutting blades 7, 37, 67, 97, 127, 157, 187. , 217, 247, 277 the blade portion (20) falls and is attached to it intact. Especially soft broken object T like polyethylene rope can be wound on cutting knife 7,37,67,97,127,157,187,217,247,277 sometimes and can't get off when broken. Once such crushed objects T adhere to the blade portion (20), sometimes the crushing effect is greatly reduced. Moreover, a large resistance can occur between the sides of the cutting knives 7, 37, 67, 97, 127, 157, 187, 217, 247, 277 during crushing, so sometimes the cutting knives will generate heat so that the crushed object melts and attaches to it, and in this case also sometimes makes the shattering effect much less effective.

Therefore, if, as shown in the above-mentioned first and second embodiments, the driving machines 5, 6, 35, 36 independently driving the two rotating shafts 2, 3, 32, 33 are provided, as shown in the time chart of Fig. 20 , forming a structure in which each rotating shaft 2, 3, 32, 33 rotates independently at different rotational speeds, even if the object T to be crushed is wound on the cutting knife 7, 37, it can be achieved by changing the two rotating shafts 2, 3, 32 , 33 speed to remove the entangled crushed object T. And as shown in this time chart, if the rotation speed of each rotating shaft 2, 3, 32, 33 is replaced with high speed and low speed, and even the control of changing the replacement of the high speed and low speed is performed, the winding can be removed more reliably. The broken object T. This is possible in all the embodiments described above.

In this way, the control device installed on the crusher has the function of changing the rotation speed of the two rotating shafts 2, 3, 32, 33, or driving the two rotating shafts 2, 3, 32, 33 alternately at high and low speeds at predetermined intervals.

21( a ), ( b ), and ( c ) are schematic views showing examples of the driving direction and driving speed of the rotating shaft of the shearing crusher according to the invention of the present application. As shown in the figure, the relationship between the driving direction and the driving speed of the multiple rotating shafts of the above-mentioned shearing crusher is as long as the method of forward rotation (both shafts are rotated to the central side) at the same rotational speed as shown in (a), (b) ) as shown in the figure (right side in the figure) with low-speed rotation forward drive method, as shown in (c), with a low speed reverse drive (clockwise drive in the figure) one of the methods can be selected.

If the forward drive is adopted at the same rotational speed as shown in (a), the object to be crushed can be embedded in two axes at once. If the method shown in (b) is used to drive one side (the right side in the figure) in the forward direction at a low rotation speed, it is possible to suppress excessive embedding of the object to be crushed. As the rotation speed difference in the rotation speed control in this case, for example, the ratio of the high-speed rotation speed to the low-speed rotation speed may be about 2:1, but other combinations are also possible. As shown in (c), it is also possible to suppress excessive embedding of the object to be crushed by driving one side (the right side in the figure) in reverse rotation at a low rotational speed. As the rotational speed difference of the rotational speed control in this case, for example, the ratio of the high rotational speed to the low rotational speed is about 10:1, and it is ideal to increase the rotational speed difference (speed difference) while maintaining the shearing effect while preventing embedding, but Other combinations are also possible. The situation of this control mode is also suitable for crushing broken objects that are easily entangled. The selection of these control modes only needs to select the ideal rotation direction automatically or manually according to crushing conditions such as the degree of easy insertion of the object T to be crushed.

By controlling the rotation of the rotating shaft in this way, it is possible to improve the crushing capacity by suppressing the occurrence of overload by controlling the insertion of the object T that is easy to be crushed.

In addition, it is possible to combine some or all of the above embodiments, and it is also possible to appropriately combine the configurations of the embodiments according to usage conditions and the like.

The above-mentioned first to eleventh embodiments are examples, and various changes can be made without affecting the gist of the invention of the present application, and the present invention is not limited to the above-mentioned first to eleventh embodiments.
