Description

Agitator

The present invention relates to a stirrer, and particularly relates to a stirrer capable of agitating the fermented food waste, as well as crushing the colloidal fermentation produced in the stirring process.

In a dry fermenter that treats food waste, it is forced to stir the food waste injected for quick and efficient drying of the food waste. In more detail, the heating means is installed in the lower part of the stirrer to which fermentation is completed, that is, in the form of porridge-type food waste (hereinafter referred to as “fermentation product”), and the fermentation product is formed by the heat generated by the heating means. To dry. However, excessive heat is supplied to the fermentate in the portion adjacent to the heating means, while the fermentate away from the heating means is not supplied with sufficient heat for drying.

In the stirrer used to prevent this phenomenon, a rotating shaft that is rotated by the driving unit is installed in the longitudinal direction of the stirrer, and a plurality of rods are fixed to the rotating shaft to be perpendicular to the rotating shaft. Therefore, each rod that rotates by rotating the rotary shaft in accordance with the operation of the drive unit is stirred fermented product.

However, the following problems also occur in the agitator having such a configuration. As the drying progresses, when the water content in the fermented product added in the form of porridge is lowered to about 60% to 70%, the fermented product becomes a rice cake colloid (colloid) state. Therefore, a large resistance force acts on the rod rotating in the fermentation colloidal state. As a result, the rotation of the rod is not made smoothly due to such a resistance force, and in severe cases, the rotation is stopped, and thus the stirring function cannot be performed, and the function of the agitator itself is also affected.

In this way, when the fermentation product is heated in a state in which stirring is not sufficiently performed, heat is not sufficiently supplied to the fermentation product separated from the heating means, thereby making it difficult to obtain a uniform dry state of the fermentation product. In addition, as the colloidal fermentation is dried without stirring, the fermentation is present in the stirrer in the form of a bulky solid mass. This type of fermentation mass, together with foreign matter such as plastic, causes damage and deformation to the rotating shaft, rod, causing fatal failure of the stirrer.

In addition, in order to process the fermented product dried in the form of a powder (powder), a separate shredding device should be used, but the price of the shredder is very expensive, it is not economically preferable to have a separate stirrer and a shredder.

The present invention is to solve the above-mentioned problems arising in the stirring process of the fermented food waste, the object is to provide a stirrer that can break down the colloidal fermentation in the stirring process.

In the present invention, two stirring cylinders are placed adjacent to each other, and the stirring function can be obtained by stirring the fermentation product using a rotating impeller, as well as a projection jaw at the boundary surface of each stirring cylinder, and a predetermined number of impellers (curved members). By forming an incision corresponding to each protruding jaw at the position, the fermented products in the aggregated state can be crushed when the fermented products are dried, thereby obtaining a fermented product of a uniform state. In particular, a crushing action takes place at the boundary between the two stirring barrels, the highest temperature portion of the stirrer, so that foreign matter such as plastic contained in the fermentation can be crushed at a high temperature.

The agitator according to the present invention, the lower portion of the inner space of the sealed housing consists of two semi-cylindrical parallel to each other in the longitudinal direction and adjacent to each other to form a first and a second stirring cylinder, each rotatable in the housing The shafts are mounted on the shafts, and a plurality of rods are provided on the surface of each rotating shaft to maintain a constant interval. Around each shaft, two impellers having different spiral directions are supported by the tip of each rod. A cutout is formed outside the end of the impeller adjacent to the tip, and a protrusion is formed on the surface of the adjacent portions of the first and second stirring cylinders corresponding thereto, and the protrusion of the impeller is formed on the surface of each stirring cylinder when the impeller is rotated by the rotating shaft. Through the fermentation product located between the incision and the protrusion is forced to crush.

In the present invention, a plurality of rods to which the impeller is fixed are fixed at regular intervals to the axis of rotation, with each rod extending through both sides of the shaft or fixed to both sides of the shaft. Each rod is orthogonal to other adjacent rods, and if the rod of one axis is horizontal, the rod of the other axis corresponding thereto is in a vertical state.

Each impeller configured around each axis consists of a plurality of curved members fixed to each rod, and each curved member is fixed to both sides of the upper rod end of one vertical rod, and another end of the curved members is adjacent to the horizontal The end of the inner rod (rod facing the stirring boundary) of the horizontal rod located on the first side of the rods and the outer rod (rod facing the housing outer wall) located on the second side (opposite to the first side) The other end of the curved member, which is respectively fixed to the end and fixed to both sides of the lower rod end of the vertical rod, is connected to the end and the second side of the outer rod of the horizontal rod (rod facing the housing outer wall) located on the first side. Respectively fixed to the ends of the inner rods (rods toward the stirring boundary) of the horizontal rods located.

Meanwhile, two impellers 210 and 220 having different spiral directions are supported by the tips of the rods 112A, 112B, 112C, 112D and 122A, 122B, 122C, and 122D around the axes 111 and 121. do.

The configuration of the impellers 210 and 220 will be described using only one axis shown in FIGS. 3 and 4 as an example. Here, for convenience of explanation, the state of the impeller 210 and 220 will be described in the state shown in FIG. 4, that is, the axis 111 is not rotated. Let's do it. The curved members 134 and 131 are fixed to both ends of the upper rod 112B-1 of one vertical rod 112B, and the other ends of the curved members 134 and 131 are adjacent horizontal rods. An inner rod 112C-2 of the horizontal rod 112C located on the left side of 112A, 112C (the rod facing the stirring vessel boundary 300) and an outer rod 112A- of the horizontal rod 112A located on the right side. 1; rods facing the outer wall of the housing).

Here, of course, another adjacent vertical rod 112D is mounted with the curved member in the opposite state as described above.

In this manner, by attaching the curved members 131.. 134, 231.. 234 to each of the rods 112A, 112B, 112C, 112D and 122A, 122B, 122C, 122D, the respective shafts ( 111, 121, two helical impellers 210, 220, 230, and 240 having different spiral directions are formed.

In each of the curved members 131.. 134, 231.. 234, a cutout portion R is formed, and a protruding jaw P for fracture is formed on the wall surface forming the boundary portion 300 of each stirring tube 110, 120, respectively. This will be described in more detail with reference to FIGS. 3 and 4.

The relationship between the curved members 131.. 134, 231.. 234 constituting the impellers 210, 220, 230, and 240 and the shredding protrusions P formed on the inner surfaces of the stirring tubes 110 and 120 is illustrated. . A protruding jaw P having a predetermined height and width is formed on an inner surface of the agitating vessel forming the boundary portion 300 of the first agitating vessel 110 and the second agitating vessel 120. It is formed at a position corresponding to both sides of each of the rods 112A, 112B, 112C, 112D and 122A, 122B, 122C, 122D.

On the other hand, the incision portion (R) outside the fixed end fixed to each of the rods 112A, 112B, 112C, 112D and 122A, 122B, 122C, and 122D in each of the aforementioned curved members 131.. 134, 231.. 234. ) Is configured, and the number of the cutout portions R is equal to the number of the corresponding projection jaw P. FIG. Each protrusion P corresponds in one-to-one correspondence with the cutout R formed in each of the curved members 131... 134, 231.. 234, and its size is slightly smaller than that of the cutout R. Accordingly, when the curved members 131.. 134 and 231.. 234 are rotated by the rotation of the respective shafts 111 and 121, each cut portion R passes over the protrusion P and the cut portion R The portion between the) passes through the space formed between the projection jaw (P) and the projection jaw (P). As a result, each of the curved members 131... 134, 231... 234 is not prevented from being rotated by the projection jaw P.

On the other hand, the rotation direction of the shaft 111 is mounted on the first stirring cylinder 110, the rotation direction of the shaft 121 mounted on the second stirring cylinder 120 is opposite to each other. As shown in FIG. 2, each of the rods 112A, 112B. 112C, 112D fixed to each axis 111 is relative to the rods 122A, 122B. 122C, 122D of the other shaft 121 even when rotating. Do not interfere with each other.

The operation and function of the present invention as described above will be described with reference to the drawings.

When fermentation products are introduced into the first and second stirring barrels 110 and 120, that is, into the housing 101, the respective driving units operate to rotate the respective shafts 111 and 121. Thus, a plurality of rods 112A, 112B. 112C, 112D and 122A, 122B. 122C, 122D fixed to each axis 111, 121 rotate, and thus the curved member 131 ..134 fixed to each rod tip. And 231.. 234, the spiral impellers 210, 220 and 230, 240 are stirred fermentation products. In particular, the curved member 131.. 134, 231.. 234 fixed to each rod passes through the protruding jaw P formed on the surface of the stirring barrel 110, 120 adjacent to the boundary 300. 131. .134, 231 .. 234 pass through the corresponding projection jaw P, so that the fermentation, in particular plastic, located between the incision R and the projection P Relatively hard foreign objects such as these are also forcibly broken.

On the other hand, in order to increase the use effect of the device in the present invention, the rotation direction of the shaft (111, 121) mounted on each stirring cylinder (11, 120) acts as an important factor. Impellers 210, 220, or 230, 240 face each rod, that is, when the impellers 210, 220, 230, and 240 rotate upward from the bottom with respect to the boundary 300 of each stirring tube 110, 120. The direction of rotation of the shafts 111 and 121 is set to rotate toward the other stirring cylinder 120 or 110. Thus, for example, the fermented product stirred and crushed in the first stirring tube 110 is moved to the second stirring tube 120 beyond the boundary 300 by the continuous rotation of the impellers 210 and 220.

In the second stirring tube 120, the above-described operation, that is, the crushing of the fermentation product by the interaction between the cutout portion R formed in the impellers 230 and 240 and the protrusion P formed on the surface of the stirring tube 120 is made. , The crushed fermented product is moved to the inner space of the first stirring tube 110 by rotating impellers 230 and 240 in the second stirring tube 120. This operation is repeated repeatedly while the apparatus is in operation.

On the other hand, as shown in Figure 2, the upper end of the boundary portion 300 of the first stirring cylinder 110 and the second stirring cylinder 120 is located below each axis (111, 112). This is to allow the rotating impeller 210, 220 and 230, 240 to easily move the fermentation product from the first stirring cylinder (or second stirring cylinder) to the second stirring cylinder (or first stirring cylinder). Of course, if the boundary portion 300 is located above or above each of the axes 111 and 112, the impellers 210, 220 and 230 and 240 are not able to move the fermentation to another stirring vessel.

As the stirring and crushing operations are repeatedly performed during the drying process of the fermentation product, the fermentation products put together in the aggregated state are crushed uniformly, and after the completion of drying, the fermentation product has a uniform particle size. In particular, the shaft in each stirring barrel is equipped with a different impeller in the spiral direction can achieve the maximum stirring efficiency of the fermentation product.

The present invention as described above can improve the stirring efficiency by placing the two stirring barrels adjacent, by stirring the fermentation product using a rotating impeller. In addition, according to the present invention, by forming a projection jaw on the boundary surface of each stirring tube, and a cutout corresponding to each projection jaw at a predetermined position of the impeller (bending member), the fermentation products of the agglomerated state when the fermentation product is dried can be broken. Particularly, in the stirrer of the present invention, a crushing action occurs at the boundary of both stirring barrels, which is the highest temperature portion, so that foreign substances such as plastics contained in the fermentation product can be crushed at a high temperature. Another effect of the present invention is that by providing a crushing function to the stirrer, it is not necessary to provide a separate crusher can improve the function of the stirrer and the efficiency of the device.
