  FIG. 11 is a partially cutaway perspective view schematically showing an example of such a conventional pulper device.

  FIG. 12 is a schematic cross-sectional view of the pulper device shown in FIG.

  As shown in each of FIGS. 11 and 12, the conventional pulper device Pc is a disaggregation tank (also referred to as a storage tank or tab; hereinafter simply referred to as a disaggregation tank) 102, a rotor 101, and a mesh plate ( Also referred to as a strainer or an extraction plate, hereinafter simply referred to as a mesh plate)) 104.

  In FIG. 11, members denoted by 105a and 105b are corrugated cardboard, used paper and other papers (raw materials) and their pulverized intermediate materials that are accommodated in the disaggregation tank 102 when the rotor 101 is driven to rotate. In addition, the guide member is prepared so that the slurry of pulverized material and water goes in the direction of the rotor 101 in the disaggregation tank 102.

  The rotor 101 is rotatably provided on a discharge port h102b at the bottom of the disaggregation tank 102 by a rotation driving means (not shown) such as an electric motor.

  The rotor 101 includes a rotor main body 101a, a plurality of blade portions 101c, and a plurality of blade portions 101c provided so as to project outward from the rotor main body portion 101a. A disaggregating blade (also referred to as a raw material cutting blade) 109... And a disaggregating blade (also referred to as a raw material cutting blade) provided at the front end in the rotational direction of the rotor 101. Hereinafter, it is simply referred to as a disaggregating blade.) 109..., Provided to protrude above each of the rotating flow generating members 110.

  The mesh plate 104 is provided at a position below the rotor 101 and on the discharge port h102b so as to cover the discharge port h102b.

  The disaggregation tank 102 is provided with a raw material input port h102a into which corrugated cardboard, used paper and other paper (raw material) are input.

  In addition, the disaggregation tank 102 includes a discharge port h102b for discharging the recycled material (slurry) at the lower part.

  Moreover, the disaggregation tank 102 is provided with the upper storage tank part 102a and the lower storage tank part 102b connected below the upper storage tank part 102a.

  In the disaggregation tank 102, in consideration of the discharge efficiency of the recycled material (slurry), the upper storage tank part 102a has a cylindrical body shape or a substantially cylindrical body shape, and the lower storage tank part 102b has a conical shape or It has a generally conical shape, and has a hopper shape as a whole.

  The mesh holes (through holes) of the mesh plate (extraction plate) 104 are sized in accordance with the size (standard) of the fibers contained in the recycled material (slurry) to be manufactured.

  Next, a method for producing a recycled material (slurry) from cardboard, waste paper, or other paper (raw material) using the pulper device Pc will be described.

  Here, a method for producing a batch-type recycled material (slurry) will be described.

  First, the discharge port h102b of the disaggregation tank 102 is closed.

  Next, corrugated cardboard, used paper and other paper (raw material) and water are accommodated from the raw material input port h102a.

  Next, power is supplied to the pulper device Pc, and the rotor 101 is rotationally driven.

  Then, corrugated cardboard, used paper, and other papers (raw materials) are cut or crushed by the disaggregating blade 109.

  Corrugated cardboard, used paper, and other paper (raw material) can be used in cooperation with the rotor body 101a and the mesh plate 104 (grinding or grinding between the lower surface of the rotor body 101a and the upper surface of the mesh plate 104) It is made fine by the cooperation of the blades 109 and the mesh plate 104 (grinding and pulverization between the lower surfaces of the disaggregating blades 109 and the upper surface of the mesh plate 104).

  Further, when the rotor 101 is driven to rotate, the corrugated cardboard, the used paper, and other papers (raw materials) and the pulverized intermediate products and the slurry of the pulverized product and water stored in the disaggregation tank 102 are generated in the rotor 101 and the rotational flow. By the members 110..., A spiral flow is generated, which moves from the rotor 101 and the rotating flow generation member 110... Toward the inner wall surface of the disaggregation tank 102, and again the rotor 101 due to the effects of the water flow guiding members 105 a and 105 b. To be sent in the direction.

  When the recycled material (slurry) is manufactured in a batch system, the rotor 101 agitates, crushes, and crushes water, corrugated cardboard, waste paper, and other paper (raw material) stored in the disaggregation tank 102 for a predetermined time. After that, the discharge port h102b is opened while the rotor 101 is rotated.

  As a result, a solution (slurry) containing fibers smaller than the meshes of the mesh plate 104 is discharged from the discharge port h102b.

  In the above description, the batch type recycled material (slurry) manufacturing method has been described. However, when the recycled material (slurry) is manufactured continuously, a predetermined mesh plate 104 is mounted on the outlet h102b, The discharge port h102b is opened, the rotor 101 is driven to rotate, cardboard, waste paper or other paper (raw material) and water are continuously supplied from the raw material input port h102a to the disaggregation tank 102, and continuously from the discharge port h102b. In addition, a solution (slurry) containing fibers smaller than the mesh of the mesh plate 104 is discharged.

  By the way, when the rotor 101 is driven to rotate the corrugated cardboard, the used paper and other papers (raw materials) and water stored in the disaggregation tank 102 using the pulper device Pc, the disaggregation tank is used. 102 vibrates. When the disaggregation tank 102 vibrates, there is a problem that noise is generated, and energy efficiency of agitation, pulverization, and mashing of water, corrugated cardboard, waste paper, and other papers (raw materials) is deteriorated.

  As a technique for preventing the vibration of the disaggregation tank 102 of the pulper device Pc and improving the energy efficiency of agitation, crushing, and grinding of water, cardboard, waste paper and other paper (raw materials) accommodated in the disaggregation tank 102 A rotor with a part has already been proposed.

Japanese Utility Model Publication No. 63-50899 JP-A-54-50607

  By the way, for example, a pulper device (not shown) provided with a conventional rotor (see the rotor 201 shown in FIG. 13, the rotor 301 shown in FIG. 15 or the rotor 401 shown in FIG. 16) provided with pump blades is used. , When stirring, pulverizing, or crushing water, corrugated cardboard, waste paper, or other paper (raw material) contained in the disaggregation tank (see disaggregation tank 102 shown in FIG. 10), the rotor (the rotor 201 shown in FIG. When the rotor 301 shown in FIG. 15 or the rotor 401 shown in FIG. 16 is driven to rotate, the pulser device Pc provided with a rotor (see the rotor 101 shown in FIG. 11) that does not have a conventional pump blade portion is provided. Compared to when stirring, pulverizing, and crushing water, corrugated cardboard, waste paper, and other paper (raw materials) contained in a disaggregation tank (see disaggregation tank 102 shown in FIG. 11). Although the vibration of the disaggregation tank (refer to the disaggregation tank 102 shown in FIG. 11) can be reduced to some extent, the vibration of the disaggregation tank (refer to the disaggregation tank 102 shown in FIG. 11) has not yet been sufficiently reduced. There was a problem.

  That is, using a pulper device (not shown) provided with a conventional rotor (see rotor 201 shown in FIG. 13, rotor 301 shown in FIG. 15 or rotor 401 shown in FIG. 16) provided with a pump blade part. When stirring, pulverizing, or crushing water, corrugated cardboard, waste paper, or other paper (raw material) contained in a tank (see the disaggregation tank 102 shown in FIG. 11), the rotor (the rotor 201 shown in FIG. 13, FIG. 15) is used. When the rotor 301 shown in FIG. 16 or the rotor 401 shown in FIG. 16 is driven to rotate, the disaggregation tank (see disaggregation tank 102 shown in FIG. 11) vibrates and generates noise. There was a problem that the energy efficiency of stirring, pulverization and mashing of other papers (raw materials) was not yet sufficient.

  FIG. 17 shows a typical attachment structure as a conventional structure for attaching a disaggregating blade to a blade portion of a rotor, and a pulper device (not shown) including a rotor 301 having a conventional pump blade portion 310 shown in FIG. The rotor 310 was driven to rotate in order to stir, pulverize, and crush water, corrugated cardboard, waste paper, and other paper (raw materials) contained in the disaggregation tank (see the disaggregation tank 102 shown in FIG. 10). It is sectional drawing explaining the problem which arises in the case typically.

  In FIG. 17, an arrow fl schematically shows the flow of water generated in the disaggregation tank 102 when the conventional rotor is rotationally driven.

  Moreover, in FIG. 17, the white arrow has shown the rotation direction of the rotor (rotor main-body part).

  Referring to FIG. 17, in the rotor 301 having the conventional pump blade portion, the wall surface Wb that is the rear position with respect to the rotation direction of each rotor 301 of the plurality of pump blade portions 310. In the direction.

  This will be explained more specifically. In the rotor 301 having the conventional pump blade portion 310, the wall surface Wb which is the rear position with respect to the rotation direction of each rotor 301 of the plurality of pump blade portions 310. The angle θc with the surface S101b of the blade portion 101b is an angle (acute angle) of 90 ° C. or less (θc is ≦ 90 degrees).

  As a result, the water and the corrugated cardboard, the used paper, and other paper (raw material) contained in the disaggregation tank (see the disaggregation tank 102 shown in FIG. 11) are stirred using a conventional pulper device including a rotor having pump blades. When the rotor is rotationally driven for crushing and crushing, water, corrugated cardboard, and waste paper are placed behind the wall surface at the rear of the rotation direction of each rotor of the plurality of pump blades 101c. A spiral flow (turbulent flow) is generated in a mixture of other paper (raw material) that is stirred and mixed.

  Spiral flow of water, corrugated cardboard, waste paper and other paper (raw materials) stirred and mixed behind the wall surface Wb, which is the rear position with respect to the rotational direction of each rotor of the plurality of pump blade portions 101c. When (turbulent flow) occurs, this spiral flow (turbulent flow) becomes a force (negative force) that prevents the rotor from rotating in the rotation direction, making it impossible to rotate the rotor smoothly. The disaggregation tank (see disaggregation tank 102 shown in FIG. 11) vibrates, and the energy efficiency of stirring, crushing, and grinding of water, corrugated cardboard, waste paper, and other papers (raw materials) is deteriorated.

  Moreover, the conventional pump blade part 210 shown in FIG.13 and FIG.14 is substantially linear, when the pump blade part 210 is planarly viewed.

  Moreover, the conventional pump blade portions 310 and 410 shown in FIGS. 15 and 16 have an arc shape obtained by cutting out a part of one circle when the pump blade portions 310 and 410 are viewed in plan.

  For example, the conventional pump blade portion 310 shown in FIG. 15 has an arc shape obtained by cutting a part of a circle having a radius R0 around the center point c0.

  For this reason, the rotor is rotated to stir, pulverize, and crush water, corrugated cardboard, waste paper, and other paper (raw materials) accommodated in a disaggregation tank using a conventional pulper device having a rotor with pump blades. When driven, the rotational speed of the pump blade is slow at the center of the rotor and fast at the outer periphery of the rotor, and the load on the outer periphery of the rotor of the pump blade becomes the load on the center of the rotor of the pump blade. Since the load on the outer periphery of the rotor of the pump blade is large, the rotational driving force of the rotor must be increased when agitating, crushing, and crushing water, cardboard, waste paper, and other paper (raw materials). There was a problem of not becoming.

  In addition, since the surface of the conventional rotor facing the upper surface of the mesh plate is flat, when the rotor is driven to rotate, the surface of the mesh plate facing the upper surface of the mesh plate and the mesh plate The side where the mixture of water and corrugated paper, used paper or other paper (raw material) stays between the upper surface and the new water and the mixture of cardboard, used paper or other paper (raw material) faces the upper surface of the mesh board As a result of the occurrence of a situation that prevents entry between the surface of the sheet and the upper surface of the mesh plate, the efficiency of crushing and crushing water and corrugated cardboard, waste paper and other paper (raw materials) is deteriorated. There was a problem that the energy efficiency of water, corrugated cardboard, waste paper, and other papers (raw materials) was deteriorated.

  In addition, in a conventional rotor for a pulper manufacturing apparatus, when a recess is formed on the surface facing the upper surface of the mesh plate, a recess is formed on the surface facing the upper surface of the mesh plate. The new rotor was replaced with a new rotor.

  When the rotor is driven to rotate when stirring, pulverizing, or crushing water, corrugated cardboard, waste paper, or other paper (raw material) stored in the disaggregation tank for many years, the present inventor noticeably vibrates the disaggregation tank. Pump blades on the rotor surface that have been engaged for many years in research and development of pulper devices that have reduced energy efficiency of stirring, crushing, and grinding water, corrugated cardboard, waste paper and other paper (raw materials) If the shape of the surface of the rotor or the surface of the mesh plate facing the surface of the rotor is devised, the water, corrugated cardboard, waste paper, and other paper (raw materials) contained in the disaggregation tank will be stirred, crushed, and ground. However, when the rotor is driven to rotate, the vibration of the disaggregation tank can be remarkably reduced, the rotational driving force of the rotor can be reduced, and water, corrugated cardboard, waste paper and other paper (raw materials) can be stirred, pulverized, and dried. Efforts were made with the knowledge that the energy efficiency of crushing is high and / or if the surface of the rotor facing the top surface of the mesh plate is devised, the rotor does not have to be replaced with a new rotor. As a result, the present invention has been completed.

  That is, in the present invention, the water contained in the disaggregation tank is devised especially by devising the shape of the pump blade provided on the rotor surface or devising the shape of the surface facing the surface of the mesh plate of the rotor. When agitating, pulverizing, or crushing corrugated cardboard, waste paper, or other paper (raw material), the vibration of the pulper manufacturing apparatus is small, the rotational driving force of the rotor can be reduced, and the rotor for the pulper manufacturing apparatus has good energy efficiency. An object of the present invention is to provide a pulper device including such a rotor for a pulper manufacturing device.

  Moreover, in the rotor for the conventional pulper manufacturing apparatus, as shown in FIG. 17, each of the plurality of disaggregating blades 109... Corresponds to the rotational direction of the rotor 301 of each of the plurality of blade portions 101 c. The bolt means v1 is attached to the wall surface Wf at the front position.

  That is, in the rotor for the conventional pulper manufacturing apparatus, as shown in FIG. 17, each of the disaggregating blades 101b... Is forward of the rotation direction of each rotor 301 of the plurality of blade portions 101c. Since the bolt means v1 is attached to the wall surface Wf at the position, the operator needs to replace the disaggregating blade 109 with respect to the wall surface Wf when exchanging the disaggregating blade 109. There is a problem that it is difficult to replace the disaggregating blade 109.

  Further, as the material of the disaggregation blade 109, a material excellent in wear resistance, for example, cobalt (Co) as a main component, about 30% chromium (Cr), 4% to 15% tungsten (W), etc. Alloys such as stellite (“Stellite” is a registered trademark of Deloro Stellite Holdings Corporation) are used.

  However, the disaggregation blade 109 using such a material has a problem that the material cost is high, and a technique for making the disaggregation blade 109 even smaller is required.

  In the present invention, when the disaggregation blade is worn by performing stirring, crushing and crushing operations of water, corrugated cardboard, waste paper and other paper (raw material) contained in the disaggregation tank, the worn disaggregation blade becomes a new disaggregation blade. It is an object of the present invention to provide a rotor for a pulper manufacturing apparatus and a pulper apparatus including such a rotor for a pulper manufacturing apparatus, which can be easily replaced and the size of the disaggregating blade is reduced. .
