BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variable rotor for an eccentric-drive rotary dewatering device, and more particularly, to a variable-diameter rotor for dewatering an eccentric- And a rotor for use in an eccentric-drive rotary dewatering device used for discharging a reduced volume.

Recently, a method of reducing the amount of sewage or sludge, impurities or food waste by mechanical squeezing and dewatering has been used to remove contaminated water contained in a dewatering object such as sludge, dirt or food waste, and to reduce the mass and volume of the dewatering object Reduction techniques are commonly used. As one of the prior arts relating to mechanical devices used for such mechanical pressing and dewatering, there has been proposed a method of "Rotary dewatering using an eccentrically driven crimping dewatering system " of Patent Document 1 of the following prior art document filed and registered by the present applicant Device ".

The "rotary dewatering device using the eccentric drive squeezing dewatering method" reduces the generation of loads concentrated on the inner and outer contact gears which contact each other when the concentric rotary force is transmitted in the eccentric rotational force in the eccentrically driven squeezing and dewatering process for squeezing and dewatering the dewatering object It is possible to increase the squeezing and dewatering force of the food garbage and to enlarge the size of the food waste, and it is not necessary to make contact with the rotary housing, which is the outer cylinder, so it is necessary to provide an additional buffering member to the rotor And the contact load is not generated in the rotor or the outer cylinder.

However, in the case of using the rotary dewatering device of the patented invention, it was confirmed that there is no problem in operation when the amount of the dewatering object is uniformly supplied to the inlet of the rotary dewatering device in an appropriate amount. However, when the supply amount of the dewatering object is not uniform and the amount of the dewatering object is supplied in a small amount, the pressure dewatering force may be lowered. On the contrary, when the amount of the dewatering object is excessively supplied, A load is applied to the rotor 140 and the rotor guide 160 during the pressing and dewatering process and the wear or breakage of the rotor 140, the rotor guide 160 or the gears 130 and 210 is severe Or the rotor shafts 110 and 190 may be deformed. This problem is caused by the fact that the shape of the rotor accommodated in the rotor guide is not variable and the volume of the receiving space of the dewatering object is constant irrespective of the amount and type of the dewatering object introduced.

It should be noted that the eccentric-drive rotary dewatering device in which the variable rotor 100 is mounted is described in detail in the patent document prior to the description, so that a detailed description thereof will be omitted.

1 to 4, a variable rotor 100 for an eccentric-drive rotary dewatering device according to an embodiment of the present invention includes a body member 110, an elastic member 130, a variable wing member 150, Member (160, 170).

The body member 110 includes a rotor body 112, a fixed blade piece 116 and an elastic member fixing pin 117. The body member 110 is made of a metal material such as STS 304 having high strength and corrosion resistance, And forms the basic structure of the variable rotor 100 through the coupling with the variable wing member 150 and the cover members 160 and 170 to be described later.

The rotor body 112 has a cylindrical shape and a rotor shaft passage hole 114 is formed at a central portion to receive the rotor shaft 10 therethrough. The rotor shaft passage hole 114 is formed in the peripheral portion 115 of the rotor shaft passage hole 114 A plurality of bolt holes 115 are formed.

The three fixed blade pieces 116 are formed to extend outwardly from the outer periphery of the rotor body 112 at an angle of about 120 degrees. The extended ends of the fixed blade cores 116 are extended in width and the uneven portions 116a are formed on the outer peripheral surface. The protruding elastic member fixing pin 117 is provided on the central front surface of each fixed blade piece 116. A recessed hinge coupling groove 118 is formed in the central rear surface of the fixed blade piece coupling hole 116. A stopper 119 are formed.

The end of the variable blade member 156 of the variable wing member 150 is brought into contact with the elastic force of the elastic member 130 by the stopper 119 contacting with the hooking protrusion 154 projected on one side of the hinge portion 152 The rotation of the variable wing member 150 in the outward direction is restricted within a predetermined angle so that collision with the rotor guide 60 does not occur.

The elastic member 130 is in contact with one surface of the variable blade piece 156 in which the concave and convex portions 156a are not formed while being received in the elastic member fixing pin 118 to provide an elastic force to the variable blade piece 156 . In the present embodiment, the coil spring is used as the elastic member 130, but it is needless to say that it can be replaced with another spring or other known elastic member.

The variable wing member 150 is also made of a metal such as STS 304 and includes a hinge portion 152 and a variable blade piece 156. One end of the variable wing member 150 is rotatably coupled to one end of the rotor body 110, Thereby making it possible to variably change the accommodation space in which the internal dewatering object is accommodated.

The hinge portion 152 is formed at the center with a hinge pin 153 coupling hole through which the hinge pin 166 is inserted and coupled to the hinge coupling groove 118.

A locking protrusion 154 is formed on one end of the outer periphery of the hinge portion 152 to restrict the rotation of the variable wing member 150 by being caught by the stopper 119 in the one-directional rotation.

Each of the variable blade pieces 156 is spaced apart from the rotor body 112 by a predetermined distance so that three ends of each of the variable blade pieces 156 are connected to the hinge portion 152, The inner surface of the other surface is a flat surface, and one end of the elastic member 130 is in contact with a part of the inner surface. When the variable blade piece 156 is rotated at a predetermined angle with respect to the hinge portion 152, the accommodating space for accommodating the dewatering object inside the rotor guide 60 can be variably changed.

The pair of cover members 160 and 170 are also made of a metal material such as STS 304 and have a triangular shape in which the corners are gradually convex to the outside as the whole is farther away from the vertexes and rotor pass through holes 164 and 174 are formed at the center And cover bodies 162 and 172, respectively. Bolt passage holes 165 and 175 are respectively formed in the periphery of the rotor shaft passing holes 164 and 174 The elastic member 130 and the variable wing member 150 are respectively coupled to both sides of the body member 110 to which the fastening bolt b and the nut n are coupled.

Scrap end portions 167 and 177 for scraping and moving the dewatering object in the moving direction together with the end of the concave and convex portion 116a of the fixed blade piece 116 are formed in the vicinity of the respective vertexes of the cover bodies 162 and 172 have.

Hereinafter, a method of operating the variable rotor for an eccentric-drive rotary dewatering device according to an embodiment of the present invention will be described in detail with reference to FIGS. 5 to 7. FIG.

5 to 7 are operational state diagrams sequentially illustrating a method of operating the variable rotor 100 for an eccentric-drive rotary dewatering device according to an embodiment of the present invention.

5A is a diagram showing the volume of the rotor shaft 10 which is caused by the eccentric rotation of the rotor shaft 10 between the variable wing member 150 and the outer cylinder 62 at the inlet port 64 side of the rotor guide 60, When the receiving space for the dewatering object is generated due to the change, the dewatering object, the sludge, food waste or the like is introduced through the inlet 64.

5 (b) shows a state in which the rotor shaft 10 starts to rotate clockwise in the clockwise direction when the object to be dewatered is started. When the rotor shaft 10 is rotated eccentrically by 90 degrees as compared with FIG. 5 (a) 62 in the counterclockwise direction. As a result, the volume of the space between the variable wing member 150 and the outer cylinder 62 is changed, and the receiving space for the dehydrating object is gradually narrowed to start the primary compression.

5 (c) shows a state in which the rotor shaft 10 continues to rotate in the clockwise direction by 90 degrees eccentric rotation as compared with FIG. 5 (b) by the start of the further introduction of the dehydrated object, The rotor 100 rotates counterclockwise along the inner circumferential surface of the outer cylinder 62 by eccentric rotation of minus 30 degrees. Thus, the space for accommodating the dewatering object is minimized between the concave-convex portion 156a of the variable blade piece 156 of the variable wing member 150 and the left-side wall of the outer tube 62, and primary compression and dehydration proceed. At this time, the dewatered object introduced through the inlet port 164 flows into the receiving space formed between the other variable wing member 156 and the outer cylinder 62. The variable wing member 150 of the variable rotor 100 is rotated by the elastic force of the elastic member 130 so that the engagement protrusions 152 of the hinge portion 152 154 can reach the left side wall of the outer cylinder 62 as much as possible until the stopper 119 is caught by the stopper 119, thereby preventing the compression and dehydration efficiency from being hindered. At this time, the irregularities 116a and 156a formed on the outer surface of the fixed blade piece 116 and on the outer surface of the variable blade piece 156 are sufficiently large in frictional force The dewatering object in which the outer ends of the end portions of the fixed blade piece 116 and the scrap end portions 167 and 177 of the cover members 160 and 170 are squeezed and dewatered is supplied to the variable rotor 100 So that the dewatered object can be prevented from moving in a direction opposite to the rotating direction of the variable rotor 100. [

When the dewatering object is heavily inflowed or the dewatering object is made of a hard material or the dewatering object includes foreign matter having a strength such as metal or wood, the variable blade piece 156 of the variable wing member 150 is pressed against the hinge part 152, The compression and dehydration of the elastic member 130 due to the shrunk elastic force of the elastic member 130 is suppressed while the elastic member 130 is contracted while the load concentrated on the end portion of the outer tube 62 and the variable wing member 150 is reduced So that it can proceed smoothly.

6 (a) is a step of additionally introducing the dewatered object and releasing the first squeezing, Fig. 6 (b) is a step of further inflow of the dewatered object and the beginning of secondary squeezing, and Fig. 6 (c) Secondary compression and dehydration step.

7 (a) shows the re-addition of the dewatered object, the primary compression and dehydration, the secondary compression release and the discharge step. Fig. 7 (b) (C) of Fig. 7 is a step of re-introduction of the dewatered object, initiation of secondary compression, and discharging to the discharge portion 66. Fig. 6 and 7 can be easily understood by referring to the prior patent document and the operation method of each step of FIG. 5, and thus a detailed description thereof will be omitted.

As described above, according to the variable rotor 100 for the eccentric-drive rotary dewatering device according to the embodiment of the present invention, in order to perform squeezing and dewatering of dewatering objects such as sludge, The variable rotor 100 can be variably changed by the variable wing member 150 that rotates in one direction or the other direction due to the elastic force of the elastic member 130 depending on the amount or type of the dewatering object into which the volume of the variable rotor 100 accommodated therein There is an advantageous effect of excellent compression and dehydration efficiency irrespective of the amount or type of the dewatered object introduced.

According to the variable rotor 100 for the eccentric-drive rotary dewatering device of the present invention, the volume of the variable rotor 100 accommodated in the rotor guide 100 in the eccentrically driven press-dewatering process for pressing and dewatering the dewatering object When the amount of the dewatered object to be introduced is excessive or the dewatering object is made of a hard material or the dewatering object includes foreign matter having a strength such as metal or wood, the variable rotor 100 may be shrunk flexibly during the squeezing and dewatering of the dewatering object. It is possible to prevent an excessive load from being applied to the rotor guide and to prevent wear or breakage of the variable rotor 100, the rotor guide 60 or the gear (not shown), the warpage of the rotor shaft 10, have.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, Of the right.

The present invention is very useful in fields related to prevention and reduction of environmental pollution to reduce the amount of discharged water by squeezing and dewatering dewatering objects such as sludge, dirt, or food wastes contained in domestic wastewater or industrial wastewater.
