Description

treatment device of mixture

The present invention relates to an apparatus for processing a mixture for fermentation or drying process for reducing food waste or for mixing dry and wet granules/powders or mixing them together at a certain ratio or stirring by stirring.

A variety of mixture processing devices have been developed and used up to now for the fermentation or drying process for reducing food waste, or for mixing and mixing dry and wet granules and powders or mixing them together at a certain ratio.

Mixture processing devices are largely divided into horizontal or vertical types, and horizontal or vertical processing devices use a stirring unit installed in the longitudinal direction in a stirring chamber provided in the body for a predetermined fermentation or drying process. Agitation should be achieved for reducing organic waste by means of agitation, mixing and mixing as desired, or mixing dry and wet granules/powders mixed in a certain ratio.

As an example of the horizontal or vertical mixture processing apparatus, the horizontal mixture processing apparatus consists of a screw or ribbon screw installed over the entire length of the stirring chamber of the fuselage, or paddles provided radially in the cross-axis direction. Fermentation or dry or wet and dry granules/powders for reducing food waste are mixed together by using a stirring unit, or agitation is achieved by mixing them together in a ratio.

In the case of using a screw, ribbon screw, or paddle, the agitation of the input food waste or dry and wet granules/powder is poor. Dead zones are occurring, and the agitation is not uniform, and agglomeration occurs frequently in the dead zones at the bottom of the stirring chamber due to the accumulated pressing pressure caused by the weight of the agitated material such as food waste or dry and wet granules and powder. Such agglomeration is accompanied by many problems, such as becoming a major factor in the driving load of the processing device.

In recent years, at least one stirring element that revolves and rotates simultaneously with the central axis installed in the mixing chamber in the mixing chamber in the longitudinal direction and rotates simultaneously using the rotating disk on the circumference of the center axis with different rotation radii. By providing a flow-type stirring unit composed of a sieve, it is prevented from occurring even mixing and agglomeration of the stirred materials without dead zones between the upper and lower sides of the stirring chamber as well as the upper and lower sides.

A mixture processing device equipped with such a fluid stirring unit is mainly used for weight loss, extinction, or composting treatment by fermenting and decomposing food waste such as food waste. Relatively low-speed operation is required for processing such as fermentation, decomposition and extinction of food waste, and drying while physically stirring.

Various transmission units for low-speed driving of the processing apparatus for such a mixture have been developed and used until now.

As an example, when a planetary gear device is used, power is transmitted from the drive motor through a power transmission member such as a chain and is engaged around the sun gear installed on the rotating drive shaft. The installed planetary gears are provided, and the shifted power is transmitted to the stirring unit centered on the drive shaft through the ring gear that is accommodated and the planetary gears are engaged and driven around the orbit. Agitating elements are processing the desired agitated material while revolving and rotating in the agitation chamber.

However, in the transmission unit using such a planetary gear device, the reduction ratio is limited, and a separate second transmission device is additionally required at either input/output stage in relatively low-speed driving, and the mechanical friction between the sun and the planetary gear or ring gear is required. There are many problems such as a decrease in driving efficiency as well as a loss of power and a high processing cost of the planetary gear device, which increases the manufacturing cost.

Therefore, in recent years, a shift stage structure innovation of the mixture processing device is required to reduce the driving load and increase the reduction ratio without a separate additional transmission device to enable low-speed driving required in the processing device.

Next, an embodiment of the present invention will be described in detail with reference to the drawings. 1 to 5 show in detail an apparatus for processing a mixture according to the present invention.

The treatment device for the mixture of the present invention is particularly suitable for reducing food waste in the fermentation or drying process for reducing food waste, or in a treatment device that stirs for mixing or mixing by mixing dry and wet granules and powders or mixing together at a certain ratio. It is an object to provide a suitable horizontal mixture processing apparatus.

The apparatus for processing the mixture has a body (10) that is approximately concave.

The body 10 has an upper surface that is opened and closed with a cover 12 and an outlet 14 is provided at the lower side of the side wall.

A horizontal stirring chamber 16 into which the agitated material for treatment is placed in a batch manner is provided in the vessel-shaped body 10 configured in this way, and the central axis installed in the longitudinal direction of the stirring chamber 16 is provided. A flow-type stirring unit 20 is provided which is installed with the rotation center 18 and is driven by a driving force transmitted at reduced speed from the driving motor M through the driving shaft 19 and the shift unit.

The stirring unit 20 revolves and rotates on a circumference of a rotating disc 22 and a rotating disc 22 and using the rotating disc 22 in parallel with the central axis 18 and with the central axis 18 as the rotating center, and the rotating radius is different from each other. It is composed of at least one or more agitating elements 24 arranged in parallel to form a, so that even mixing and agglomeration of the agitated material does not occur without dead zones in the stirring chamber 16 .

This configuration is the same as the prior art, and the core technology of the present invention is to reduce the driving load and increase the reduction ratio without a separate additional transmission device to enable low-speed driving required in the processing device. There is a characteristic.

The present invention shift unit (TM) has a housing (100).

The housing 100 is formed by arranging in parallel a stator 110 whose body is divided into left and right and is constrained to the side wall of the body 10 and a rotor 120 freely installed on the side wall of the body 10 .

On the inner circumference of each of the stator 110 and the rotor 120, the ribs 111a and 121a of the row are provided with ribs 111 and 121 formed at equal intervals.

First and second eccentric cams ( 112,122). Here, the first and second eccentric cams 112 and 122 are installed integrally with the driving shaft 19 and rotated by the driving force transmitted from the driving motor M.

Between the housing 100 and the drive shaft 19, the first and second disk-shaped first and second planetary plates 113 and 123 are respectively coupled to each other in an idling state with the first and second eccentric cams 112 and 122 by being coupled to each other on opposite surfaces. ) is interposed.

The first and second planetary plates 113 and 123 are the roll rows 113a and 123a formed of rolls 113a-1 and 123a-1) provided at equal intervals on the outer periphery of the fixed and rotor 110, 120, respectively. It is provided asymmetrically with the first and second eccentric cams 112 and 122 to achieve a circular motion by a rolling motion in an alternating engagement relationship at a point coincident with the top dead center of the first and second eccentric cams 112 and 122.

Here, the asymmetric relationship between the roll rows 113a and 123a and the bone rows 111 and 121 is fixed, and the bone rows 111 and 121 of the rotor 110 and 120 are the roll rows 113a and 123a of the first and second planetary plates 113 and 123. ) greater than, in other words, the number of the valleys 111a and 121a of the ribs 111 and 121 is greater than the number of the rolls 113a-1 and 123a-1 of the roll rows 113a and 123a by at least one or more.

In the shift unit TM configured in this way, when the driving force is transmitted from the driving motor M and the driving shaft 19 rotates, the first and second planetary plates around the inner circumference of the stator and the rotor 110 and 120 of the housing 100, respectively. The rotational speed of the driving motor M is doubled in 1st and 2nd steps due to the circular motion by the rolling motion of the fields 113 and 123 and transferred to the rotating plate 22 of the stirring unit 20 through the rotor 120 This will allow the desired stirring process to be achieved.

And the second planetary plate 123 is freely installed on the drive shaft 19 concentric with the drive shaft 19, and connected to the stirring elements 24 of the stirring unit 20 and the chain belt 25 of the endless track. A mediator 130 that transmits the driving force to the side of the chain gear 26 is installed one after another.

The mediator 130 is coupled in an idle state with the second planetary plate 123 using the third eccentric cams 132 installed in the same phase as the second eccentric cam 122 around the periphery to the second planetary plate 123 . Simultaneously with the offset of the eccentricity in , it will transmit the first reduced driving force of the driving motor M toward the stirring elements 24 of the stirring unit 20 .

Then, with reference to FIGS. 7 to 9, the process of shifting the processing apparatus of the inventive mixture will be described.

7 and 8 are explanatory diagrams showing a process in which the stator 110 and the rotor 120 of the shift unit MT cooperate with each other to reduce the rotational speed of the driving motor M in primary and secondary stages am.

First, FIG. 7 shows the shifting process at the stator 110 side as the primary deceleration step.

When explaining the primary deceleration step, when the driving force is transmitted from the driving motor M, the driving shaft 19 rotates in the clockwise arrow direction shown in the drawing. At this time, the first eccentric installed integrally with the driving shaft 19 . The cam 112 also rotates clockwise together with the drive shaft 19 .

When the first eccentric cam 112 rotates clockwise together with the drive shaft 19 in this way, the first eccentric cam 112 on the stator 110 side constrained to the body 10 coincides with the displacement top dead center in the clockwise rotation. At the point where the first planetary plate 113 is formed, the first planetary plate 113 is formed by the rolling motion occurring in the alternating meshing relationship between the roll row 113a of the first planetary plate 113 and the stator 110 bone row 111. ) of the trough (111a) and rotates in the counterclockwise direction indicated by the arrow in the drawing, that is, in the reverse direction of the rotation of the drive shaft 19, and achieves deceleration.

To explain this further, during one rotation of the drive shaft 19, the first planetary plate 113 is driven while being reversely rotated at an angular speed passing through one of the bone rows 111 provided around the inner circumference of the stator 110. The rotation speed of the motor (M) is first reduced.

8 shows the shifting process at the rotor 120 side as the secondary deceleration step.

When describing the secondary deceleration step, the second planetary plate 123 is rotated at the same speed in the counterclockwise direction indicated by the arrow in the figure by being coupled to the first planetary plate 113 in FIG. At this time, on the side of the rotor 120 installed in a free state on the body 10, the second eccentric cam 122 at a point coincident with the displacement top dead center in the clockwise rotation of the second planetary plate 123 (123a) The second planetary plate 123 rotates in the counterclockwise direction indicated in the drawing, that is, in the reverse direction of the rotation of the drive shaft 19, by the rolling motion in the alternating engagement relationship of the rotor 120 and the bone row 121. slow down

To explain this further, the second planetary plate 123 is driven while being reversely rotated at an angular speed that pushes the one bone 121a of the rotor 120 by repeating the reverse rotation of the first planetary plate 113 . The rotation speed of the motor M is reduced secondarily.

The driving force output by finally decelerating the rotational speed of the driving motor M through the rotor 120 of the shifting unit MT will drive the rotating disc 22 of the stirring unit 20 at a relatively low speed.

9 is a primary decelerated driving motor M transmitted from the second planetary plate 123 interlocking with the first planetary plate 113 on the stator 110 side from the rotor 120 side of the shift unit MT. ) is an explanatory diagram showing that the eccentricity with the second planetary plate 123 is offset in the process in which the driving force is transmitted to the stirring element 24 of the stirring unit 20 through the mediator 130 .

To explain this further, the mediator 130 is coupled to the second planetary plate 123 in an idle state using the third eccentric cams 132 installed in the same phase as the second eccentric cam 122 on the drive shaft 19 . , the eccentricity between the second planetary plate 123 and the mediator 130 is offset in a complementary relationship by the third eccentric cams 132 idling on the second planetary plate 123 .

In this way, the rotation speed of the driving motor M in the shift unit MT is repeatedly and multiplicatively decelerated to rotate the rotating plate 22 of the stirring unit 20 at a relatively low speed, so that the fermentation process efficiency of food waste You will be able to maximize the weight loss by increasing it.

Although one embodiment of the present invention has been described as described above, the present invention is not limited thereto, and changes may be made within the scope described in the claims.
