  In the above table, [Structure pattern 2] in the center of the table shows a structure pattern in which the outer blade and the inner blade are alternately bridged between the long support branches of each node along the axial direction of the stirring shaft. (B, C, F, G, J, K, N, O). A series of continuous stirring blades formed by this structure pattern has a shape in which the stirring shaft spirally circulates along the axial direction. Therefore, in the present invention, the structure of the stirring blade is defined as a spiral blade structure.

  On the other hand, in the case of [Structure pattern 1] in the above table, a structure pattern is formed in which the tops of the short support branches are bridged to each other by an inner blade every odd section (A, E, I, G, M ). In the case of [Structure pattern 3], a structure pattern is formed in which the tops of the long support branches are bridged to each other by the outer blade in every even section (D, H, L, P).

  In the present invention, the structural pattern of the agitating blade in which the [Structural Pattern 1] and [Structural Pattern 3] are combined, that is, the bridging section of the inner blade and the outer blade along the axial direction of the stirring shaft is provided for each node section. The structure pattern of the stirring blade appearing alternately and intermittently is defined as an intermittent blade structure.

As described above, a stirring blade is not carried on one of the long support branches or the short support branch planted on the support branches at both ends of the stirring shaft. Instead, the stirring plate 15f (in the drawing) The symbols Q, R, S, T) are provided. This has the role of pushing back the pulverized material that tends to accumulate at the four corners of the agitation treatment tank back to the agitation shaft in the course of the pulverization / stirring treatment of the agitation treatment product.

  The main point of the present invention is that the stirring efficiency is drastically improved by combining the two stirring blade structures of the helical blade structure and the intermittent blade structure described above along the axial direction of the stirring shaft. In the point.

  Then, the front view seen from the axial direction of the stirring shaft 15 is shown in FIG. As shown in the figure, from the viewpoint of the axial direction, the spiral blade structure and the intermittent blade structure are observed in an overlapping manner. Therefore, a fan-shaped collective shape in which the circumference having the long support branch 15c as a radius is divided into three parts at intervals of 60 degrees (the outer periphery of the fan shape becomes the outer blade 15e), and the short support branch 15b is defined as a radius. The two fan-shaped collective shapes of the fan-shaped collective shape (the fan-shaped outer peripheral portion becomes the inner blade 15d) that are divided into three at intervals of 60 degrees appear to overlap each other at 60 degrees apart from each other. become.

  The stirring blade pulverizes and stirs the stirred product in the treatment tank, and a normal plate-like structure is sufficient. In the present invention, the stirring blade is called a “blade”, but particularly its outer edge portion. There is no need to provide a shearing blade. However, for example, in the case of pulverization / stirring treatment for relatively hard solids and semi-solids, the crushing effect on the stir-processed product is enhanced by using a stirrer blade having a sharp outer edge. Is also possible.

  In the examples shown in the above drawings, the outer edge portions of both the inner blade 15d and the outer blade 15e are expressed as arcs. However, the present embodiment is not limited to this. For example, the shape of the stirring blade may be a simple rectangular plate shape, or the shape of the outer edge is formed into a special curve or straight line such as a crescent moon or a part of a sine wave, or a combination thereof. May be.

  Next, the stirring processing apparatus using the stirring shaft according to the present invention will be described. First, FIG. 4 shows a schematic perspective view of an agitation processing apparatus 10 (hereinafter simply referred to as “this apparatus”) according to the present invention. It should be noted that the various mechanical parts / devices, electronic parts / devices, piping / wiring members, etc. included in this device are only those that are directly related to the gist of the present invention, and others The description is omitted.

  As shown in the figure, the processing tank 11 for performing the stirring process has a generally rectangular box shape that is sealed. An exhaust tower 12 is provided on the ceiling of the processing tank 11 and plays a role of extracting various gases filled in the tank. Although not shown in FIG. 4, the exhaust tower 12 may generally be provided with auxiliary equipment such as a forced exhaust fan, a purification filter, or a deodorizing device.

  In addition, the ceiling of the processing tank 11 is provided with a charging port 13 for charging the processed product (the description of the lid is omitted), and the processed product after stirring is provided on the side surface of the processing tank 11. An unloading door 14 is provided for unloading. Note that the description of FIG. 4 merely shows an embodiment of the present apparatus, and the size, outer shape, appearance, position / shape of the inlet / outlet door, etc. are shown in FIG. It is not limited to the case that is.

  As a material constituting the treatment tank 11, it is possible to use general steel materials, reinforced durable resins, or other building materials, but the mechanical strength and durability, or the corrosion resistance and heat resistance. In view of this, it is preferable to use a stainless steel material as the material used. In addition, it is preferable to use a stainless steel material as a raw material for each component member of the apparatus described later.

  Inside the processing tank 11, two stirring shafts 15 and 15 'are provided side by side in the longitudinal direction, and the state is shown in an open cut view of the processing tank 11 (see FIG. 5). Each of the two stirring shafts has the same structure, and the detailed shape and structure thereof are as described above. Further, the stirring shafts 15 and 15 ′ are supported on the short side walls on both sides of the processing tank 11 in a rotatable manner via a general bearing mechanism 11 a such as a sliding bearing or a bearing bearing.

  The stirring shafts 15 and 15 ′ are connected to an electric motor 16 provided adjacent to the processing tank 11 through a gear / transmission mechanism (not shown). The electric motor 16 is a normal specification used for general industrial equipment, and since it is not directly related to the gist of the present invention, the description thereof is omitted. In addition, about these apparatuses, the thing of various ratings and characteristics, such as the output and rotation speed, can be suitably selected and used according to embodiment, such as the magnitude | size of a processing tank, and the quantity of a stirring processed material.

  In the present invention, the two agitation shafts 15 and 15 ′ provided in parallel in the treatment tank are set in advance to rotate synchronously in the reverse direction by a gear / transmission mechanism (not shown). . That is, the power from the electric motor 16 is transmitted to the two agitation shafts 15 and 15 'via the gear and transmission mechanism, and each agitation shaft is adjusted to rotate in the opposite directions at the same rotational speed. It shall be.

  Since the electric motor 16 can be switched between forward and reverse rotations, by switching the rotation direction of the electric motor 16, the two agitation shafts can be turned inwardly (in the direction in which the two agitation shafts rotate inward) and outwardly. Two types of rotational motion patterns can be created (in the direction in which the two stirring shafts rotate outward from each other).

  FIG. 6 shows a front view seen from the axial direction when two stirring shafts 15 and 15 ′ are installed in parallel inside the treatment tank 11. In the present invention, the distance between the two stirring shafts is set to the added value of the length of the long support branch and the length of the short support branch. For this reason, when the two stirring shafts rotate, the stirring blades provided on the respective stirring shafts do not interfere with each other to cause a problem. Note that the distance between the axes can be changed in accordance with the amount and attributes of the processing object to be stirred.

  In the operation of this apparatus, it is preferable to perform the stirring process by appropriately combining the above two rotation operation patterns. For example, an internal mode is set for an external sequence controller (not shown) such that a series of operations are repeated 10 times, with an internal rotation for the first 20 minutes and an outward rotation for 10 minutes. You may make it drive | work. Moreover, it is good also as a structure which provides the heat retention / air blower 17 in the exterior of the processing tank 11, and sends a hot air, a cold wind, etc. in the inside of a processing tank according to the attribute of a processed material during the stirring process.

  As described above, the stirring shaft of this apparatus has a unique stirring blade structure that combines a spiral blade structure and an intermittent blade structure, and the two stirring shafts are close to each other. Since they are arranged side by side, a sufficient clamping pressure is applied to the stirred product from the stirring blade, and the processed product is immediately crushed and stirred without sticking in a dumpling form.

  The stirred product is stirred while moving in the longitudinal direction in the treatment tank by the rotation of the stirring shaft and the stirring blade, but the stirred product brought to the four corners in the treatment tank is stirred. The stirring plates (symbols Q, R, S, and T in the figure) provided at both ends of the plate are pushed back in the direction of the stirring shaft, so that the stirring processed product is not clogged at the four corners in the processing tank.

Or in the case, 攪拌process when juxtaposed the stirring shaft of the two in the processing tank of the apparatus is been explained as an example, embodiments are not limited to the examples according to the present invention. For example, three or more stirring shafts may be juxtaposed in the treatment tank, and the stirring processing may be performed by rotating adjacent stirring shafts in opposite directions.

  The embodiments of the present invention are not limited to the examples described above. For example, the shape and arrangement of each part constituting each of the examples, or the material thereof is the gist of the present invention. It goes without saying that changes can be made as appropriate according to actual embodiments without departing.
