Description

[Detailed description of the invention] The present invention relates to a stirring device, in particular a horizontal stirring device.

Stirring equipment for stirring and mixing foods and medicines must be maintained in a clean condition. To this end, it is necessary to create a structure that allows complete and easy cleaning after use. An object of the present invention is to provide a stirring device that can be completely and easily cleaned.

Another object of the present invention is to provide a stirring device in which a stirring blade can be removed from a stirring container. The present invention will be explained in detail below with reference to the drawings. As shown in FIG. 1a, the stirring device 1 of the present invention has a stirring shaft 2 and indexing means 4. As shown in FIG. One end 20 of the stirring shaft 2 protrudes into the container through a side wall through hole 50 of the container 5, and the other end 21 is connected to stirring drive means (not shown) via a rotational drive shaft 6 outside the container.
The stirring blade 3 is fixed to the stirring shaft 2 in the container 5 by means such as welding. The indexing means 4 outside the container is connected to, for example, an air cylinder, and constantly indexes the stirring shaft 2 toward the outside of the container. This indexing means 4 is detachably connected to the stirring shaft 2 at the other end 21 of the stirring shaft. Stirring shaft other end 2
1 is removably connected to a rotating and driving shaft 6 having a spline, as shown in FIG. 1b, for example. The other end 21 of the stirring shaft 2 can be detachably connected to the rotary drive shaft 6 through a pin, as shown in FIG. 1c. The airtight mechanism between the stirring shaft 2 and the container 5 is such that the indexing means 4 constantly indexes the stirring shaft 2 in the axial direction toward the outside of the container, so that the flange 22 at a predetermined position of the stirring shaft is inserted into the container wall through-hole through the packing 51. This is achieved by abutting the periphery of 50. The stirring blade 3 includes a plurality of stirring arms 31 fixed to the stirring shaft 2 by means such as welding, a blade support arm 32 that is detachably connected to the stirring arm 31, and a blade support arm 32 that can be detachably attached to the blade support arm 32. The sliding blade 33 is sandwiched between the sliding blades 33.

The stirring arm 31 supports a cylinder 311 at its tip.
The cylinder 311 is provided with a notch 312 in the axial direction.
The blade support arm 32 consists of a cylindrical base 321 and a plate-like main body 322, as shown in FIGS. 2a and 2b. The plate-like main body 322 extends perpendicularly to the cylindrical axis direction from the side of the base portion 321, and its tip constitutes a holding portion 323 having a substantially U-shaped cross section, and holds the sliding blade 33 therebetween. This blade support arm 3
2 is attached to the stirring arm 31 so that the cylindrical base 321 fits into the cylinder 311 at the tip of the stirring arm and the plate-like main body 322 protrudes outward from the cylinder 311 via the notch 312, as shown in FIG. Join. Therefore, the blade support arm 32 is prevented from sliding relative to the stirring arm 31 in a direction perpendicular to its cylinder axis. The sliding blade 33 is fitted into and held by the blade support arm clamping part 323, and is moved in a direction perpendicular to the cylinder axis relative to the blade support arm 32 by an engaging part, for example, a protrusion 324, provided parallel to the cylinder axis. is prevented from sliding. Further, near the tip of the stirring arm 31, there is an engaging portion, for example, an engaging recess 340 of a predetermined width, and an engaging protrusion 31 at the center thereof.
0, and a notch 320 of a predetermined width is provided near the center of the blade support arm plate-like body 322.

Furthermore, as shown in FIGS. 3a and 3b, the sliding blade 33
A recess 330 is provided at a position aligned with the blade support arm plate cutout 320 . Therefore, the blade support arm 32 is fitted onto the stirring arm 31 and the sliding blade 3
3 is fitted into the blade support arm clamping part 323, and then, as shown in FIG. This stirring arm 31 is configured to engage with the arm 31 and press the sliding blade 33 in the rotational direction while the other end engages with the sliding blade recess 330 through the notch 320 of the blade support arm plate-like body 322. By attaching it, it is possible to prevent the blade support arm 32 and the sliding blade 33 from sliding with respect to the stirring arm 31 in the cylinder axis direction. This spring plate 34
At the same time, the sliding blade 33 is brought into contact with the inner wall of the container with an appropriate pressing force. Notch line 3 of the stirring arm cylinder 311
12 is cut out wider than the plate thickness of the blade support arm plate-like main body 322 that fits into the cutout strip 312.

Therefore, the sliding blade 33 can slide on the inner wall of the container 5 with an appropriate pressing force due to the spring pressure of the leaf spring 34. The above-mentioned stirring shafts 2 usually consist of a pair, extend into the container from both side walls of the container 5 through a through hole, and are arranged such that one end of each shaft is opposed to each other in the container 5. Note that, when the object to be stirred is, for example, a low viscosity liquid, the stirring blade 3 is connected to the stirring arm 3.
It can also be configured with only one. Since the surfaces of the stirring arm, blade support arm, sliding blade, presser spring plate, etc. are made smooth, there is no risk of retention of the residue of the stirred material, which may cause the generation of microorganisms.

Furthermore, all parts are removable and no bolts or nuts are used; all joints are welded. Therefore, cleaning of each part can be done thoroughly and with great ease. Since the stirring device of the present invention has such a structure and function, it exhibits excellent effects corresponding to the above object.
