Abstract

The present invention relates to a stirring device of a digester with a planetary gear. The present invention stirs an organic matter of a center unit of the digester by rotating a planetary gear stirring shaft connected to a carrier when a ring gear is fixed; stirs surroundings of an inner wall of the digester by rotating a ring gear stirring shaft connected to the ring gear when the carrier is fixed; and provides two stirring methods for stirring an inside of the digester with one power. Therefore, a stirring effect of the organic matter in the digester can be maximized. The present invention provides a stirring plate which differs from stirring efficiency of a conventional screw stirring method, so that a large scale of stirring is performed in rotation of one direction in which the stirring plate is unfolded. Since low power is required in one direction in which the stirring is folded, the stirring is performed with low required power in rotation of the one direction in which the stirring plate is folded when the organic matter with high viscosity and low fermentation is initially stirred. The more large scale of stirring is performed by rotating and stirring the organic matter in the direction in which the stirring late is unfolded after decreasing the viscosity of the organic matter.

  In order to uniformly ferment the microorganisms throughout the digestion tank, the inside of the digestion tank must be uniformly stirred. As the organic matter has a high viscosity, a large amount of power is required for stirring, and depending on the type of digestion tank There has been a problem that stirring can not be performed with one stirring screw when the digester is wide.

  In order to solve the above problem, the anaerobic microorganisms are used for digesting organic matter, and a motor used as a power source for stirring the digester is provided. And

  The planetary gear shafts and the ring gear stirring shafts are of a variable length type, and the planetary gear shafts and the ring gear stirring shafts are of a variable length type.

  Wherein the planetary gear stirring shaft and the ring gear stirring shaft change the length of the shaft using hydraulic, pneumatic, or gears, wherein the axis of the stirring plate shaft or the stirring screw shaft length variable type planetary gear unit power transmission structure Lt; / RTI >

 The present invention also provides a lubrication system for a liquefied petroleum distillate and a high concentration organic material digestion tank, wherein the length of the planetary gear stirring shaft and the ring gear stirring shaft is changed when the digester is stopped.

 Also, it is possible to provide a planetary gear train power transmission structure in which the lengths of the planetary gear stirring shaft and the ring gear stirring shaft are changed during the operation of the digester, and the stirring plate shaft or stirring screw shaft length-variable power transmission structure of the high concentration organic matter digestion tank.

 The stir plate is folded so that when the stir plate is rotated to one side, the stirring plate is not folded when the stir plate is rotated to the other side. When the viscosity of the inside of the digester is high, the stir plate is rotated to one side where the stir plate is folded. And the rotation of the agitation plate is controlled to the other side where the agitation plate is not folded.

When the ring gear is fixed by the above-described constitution of the present invention, the planetary gear stirring shaft connected to the carrier rotates and stirs the organic matter in the center of the digester, and when the carrier is fixed, the ring gear stirring shaft connected to the ring gear rotates By stirring around the inner wall of the digestion tank, two stirring methods capable of stirring the inside of the digestion tank as a whole are provided as a single power, thereby maximizing the effect of stirring the organic substances in the digestion tank.
Further, by adjusting the lengths of the ring gear stirring shaft and the planetary gear stirring shaft during operation of the digester or during operation of the digester, the stirring in the vertical direction inside the digester can be performed to further maximize the stirring effect of the organic matters in the digester It is effective.
In addition, since the conventional screw stirring type and the stirring plate having different stirring efficiency are provided, the stirring is performed on a large scale over a wide range in the one direction in which the stirring plate is not folded, and the small power is required in the one direction in which the stirring plate is folded In the initial agitation of the organic material having a high viscosity and less fermentation, the agitating plate is rotated to the folding side so that the agitating can be performed while the required power is decreased. After the viscosity is lowered, the agitating plate is rotated in the direction of not folding, And the stirring of the water is performed.

  The present invention relates to a skewer type stirring structure of a livestock feed and a high concentration organic matter digestion tank, and stirring of the inside of the digestion tank is most important in the operation of the anaerobic digestion tank. Stirring the entire digester with a single screw requires a great deal of power, and the use of multiple screws also requires a large number of power generators.

  In order to solve the above-mentioned problems, the present invention provides a method of stirring organic matter in a digester by two methods using one power unit.

  The planetary gear of FIG. 3 was used for this purpose. The planetary gear is constituted by an input shaft and a sun gear which receive power, a pinion which rotates between the input gear and the ring gear and transmits power, and a carrier which connects the two or more pinions, and a ring gear which is located outside the pinion. At this time, when the ring gear is fixed, the sun gear rotates the pinion and the carrier together, and when the pinion is fixed, the ring gear rotates.

  In other words, the output of two different gears can be produced by adjusting the rotation and fixing of the pinion and the ring gear.

  The present invention relates to an electronic or manual rotary brake for fixing or rotating a hub connected to a carrier on the top of a carrier for connecting a pinion as shown in FIG. 4 using the above-mentioned operating principle of the planetary gear, An electronic or manual rotary brake is provided at an upper portion of the ring gear to fix or rotate the rotation of the ring gear. An axis for outputting the rotation of the pinion and a shaft for outputting rotation of the ring gear are provided. It is an object of the present invention to provide an apparatus capable of stirring an anaerobic digester in two modes. In particular, since the pinion located at the center and the shaft connected to the carrier have a large deceleration ratio, they can have a sufficient torque and can connect a plurality of screws to the shaft or use a large screw. It is possible to use several shafts because it is possible to stir in a rotating form. In addition, if both the pinion and the shaft connected to the carrier and the shaft connected to the ring gear are used, it is possible to control the position of the screw so that efficient stirring in the vertical direction of the digester can be performed.

  In the present invention, the shaft can be used as a hydraulic and pneumatic cylinder capable of changing the length and a shaft connected to the shaft. In addition, any structure can be used as long as it can change the length.

  In addition, since the rotation of the rotating shaft is slow due to the large reduction ratio, it is possible to provide a plate-like stirring plate having a large resistance but a relatively large stirring efficiency. This stirring plate is capable of folding the center portion in one direction. When the rotating portion is rotated in one direction, the folding portion is not folded, so that the stirring portion undergoes a large resistance and is rotated.

  When the viscosity of the inside of the digester is high, the stirring plate is folded. When the inside of the digester is low, the stirring plate is rotated to the side where the stirring plate is not folded. And the like.

  In addition, since the length of the shaft having the stirring plate can be adjusted, the entire digestion tank can be stirred, and the stirring portion can be determined by the lower portion, the middle portion, and the upper portion.
