Description

TECHNICAL FIELD The present invention relates to a stirring swirl device and a stirring device suitable for stirring high-melting adhesive materials.

BACKGROUND ART Conventionally, there is a stirrer described in Patent Document 1 as a stirring device. This stirrer is equipped with scraping blades, and can scrape and stir the object to be stirred in the stirring vessel while being heated by the rotation and revolution of the scraping blades.

When a high melting point adhesive material in a molten state such as candy and a particulate solid are stirred and mixed with such a stirrer, the high melting point adhesive material adheres to the scraping blade and the shaft supporting the blade on the rotating part, Deposits will grow and increase over time.

In particular, the blade pipe or the like that supports the scraping blade on the rotating part is made of metal because it is necessary to maintain strength because it receives resistance due to stirring from the object to be stirred during the scraping and stirring process. For this reason, when a molten high-melting-point adhesive material adheres to a vane pipe or the like, it tends to grow as a deposit.

This adherent has a history of being heated and mixed unevenly and insufficiently compared to the product, and if the peeled adherent is mixed with the product, there is a problem that the quality of the product becomes uneven.

In addition, there are problems such as an increase in cleaning time for removing deposits from scraping blades and the like after completion of production, and a decrease in product yield due to increased deposits.

For this reason, it is essential to suppress the growth of deposits in the scraping and stirring process that accompanies heating of the high-melting-point adhesive material.

In addition, when the high-melting-point adhesive material is transferred to another agitating device or the like for subsequent processing, the growth of such deposits can also occur in a transfer chute or the like where heat such as gas heating is difficult to reach. Therefore, it is also important to suppress the growth of deposits.

The blade pipe 23 and scraping blade 27 and the blade pipe 25 and scraping blade 29 have substantially the same structure and relationship, and the blade pipe 23 and scraping blade 27 will be described with reference to FIGS. However, description of the blade pipe 25 and the scraping blade 29 is omitted.

FIG. 2 is a schematic front view of a state in which scraping blades are attached to support rods according to the first embodiment. FIG. 3 is a cross-sectional view taken along line III-III in FIG. 2 according to the first embodiment. FIG. 4 is a cross-sectional view taken along line IV-IV in FIG. 3 according to the first embodiment. FIG. 5 is a rear view of the scraping blade attached to the blade mounting plate according to the first embodiment.

As shown in FIGS. 2 and 3, a scraping blade 27 is connected to the tip of the blade pipe 23 .

The vane pipe 23 is formed of stainless steel or the like in a cylindrical shape, and has a cover member 35 made of fluororesin attached to its upper portion, and a knuckle portion 37 made of stainless steel or the like as a vane support portion attached to its lower portion. The outer diameter of the knuckle portion 37 is set to be the same as the outer diameter of the blade pipe 23 .

A spring receiver 47 is fixed to the mounting shaft 39 on the lid member 35 side. A coil spring 49 is arranged between the spring bearing 47 and the guide pipe 44 .

Therefore, when the blade pipe 23 receives a pushing force from the side of the scraping blade 27 through the knuckle portion 37, the blade pipe 23 moves upward while the guide hole 44a is guided by the guide piece 45. As shown in FIG. Due to this movement, the vane pipe 23 contracts upward relative to the mounting shaft 39 . At this time, the coil spring 49 pressed against the guide pipe 44 is received by the spring receiver 47, and the coil spring 49 is compressed.

When the thrusting force to the vane pipe 23 disappears, the resilient force of the coil spring 49 is input to the vane pipe 23 through the guide pipe 44 , and the vane pipe 23 extends and moves relative to the mounting shaft 39 .

The bolt 57 has an enlarged fitting portion 57a outside the knuckle portion 37, and has a bolt head on the end surface of the enlarged fitting portion 57a.

The vane pipe 23 has a supporting rod covering portion 59 forming an outer shell. The support rod covered portion 59 is made of a material having relatively low thermal conductivity with respect to the vane pipe 23 . The material of the supporting rod cover portion 59 is fluororesin in this embodiment.

The supporting rod cover portion 59 is a cover tube made of fluorine resin which is formed in a substantially cylindrical shape and encloses the vane pipe 23 therein. The inner diameter of the support rod cover portion 59 is approximately the same as the outer diameter of the vane pipe 23 . The wing pipe 23 is enclosed by the support rod covered portion 59 from the lower end of the wing pipe 23 to about half in the axial direction. However, it is also possible to adopt a configuration in which the entire blade pipe 23 is enclosed by the support rod cover portion 59 .

The upper end of the support rod cover portion 59 is abutted against the stopper ring 38 .

A pair of cover tongues 59c and 59d are integrally protruded from the lower end of the support rod cover portion 59. As shown in FIG. The cover tongue portions 59c and 59d are formed so as to increase in wall thickness toward the inner side of the support rod cover portion 59 in the cylinder radial direction, and face the blade-side attachment portion 59 in a plane. One cover tongue portion 59d is chamfered 59e according to the rake angle of the scraping blade 27. As shown in FIG. Alternatively, the lower end of the support rod covered portion 59 may be formed in a bottomed shape, and a slit may be formed in the bottom portion so that the blade-side mounting portion 59 may pass therethrough.

A radial through-hole 59f is formed in the support rod covered portion 59 adjacent to the cover tongue portion 59c. A fitting enlarged portion 57a of the bolt 57 is fitted into the through hole 59f.

The support rod covered portion 59 is axially positioned by the stopper ring 38 and the enlarged fitting portion 57a.

Thus, the support rod cover portion 59 forms the outer shell of the vane pipe 23 . In this state, the supporting rod covered portion 59 covers the blade side mounting portion 55 including the knuckle portion 37 .

However, the range in which the support rod cover portion 59 covers the blade pipe 23 can be freely set.

The blade mounting plate 51 is provided with a mounting plate covering portion 63 covering the blade mounting plate 51 . The mounting plate covering portion 63 is made of a material having relatively low thermal conductivity with respect to the blade mounting plate 51 . The material of the mounting plate covering portion 63 is fluororesin in this embodiment. In other words, the mounting plate cover portion 63 is a fluororesin cover plate that covers the rear surface of the blade mounting plate 51 . The mounting plate covering portion 63 substantially covers the rear surface of the blade mounting plate 51 as shown in FIGS. The peripheral edge of the mounting plate cover portion 63 is chamfered. The mounting plate cover portion 63 is fastened and fixed to the blade mounting plate 51 with two screws 65 .

In this embodiment, the vane pipe 25 has substantially the same structure as the support rod cover portion 59 in FIG. 1, and the blade mounting plate of the scraping blade 29 has the same structure as the mounting plate cover portion 63 in FIGS. I have.

The outer peripheral scraping blade 33 is attached to the blade pipe 31 by a blade mounting plate made of stainless steel or the like, like the scraping blades 27 and 29 . Therefore, the scraping blade 33 also has a similar structure, and the blade mounting plate has a structure similar to that of the mounting plate covered portion 63 in FIGS. 3 and 5 . However, the scraping blade 33 has a different shape from the scraping blades 27 and 29, and the shape of the blade mounting plate is also different. Needless to say, the mounting plate cover portion attached to the differently shaped blade mounting plate is formed in a shape that covers the blade mounting plate.

The vane pipe 31 is arranged at a relatively high position in the stirring vessel 3 and does not come into contact with the treated material such as the adhesive material, so it does not have a supporting rod covered portion. However, in the form in which the material to be processed adheres to the blade pipe 31, the supporting rod covered portion may be provided.

[Stirring drive]
The stirring container 3 of the stirring device 1 is heated and controlled by a gas heating device when the stirring swirl device 5 is in operation. In the stirring device 1 , rotational driving force is transmitted to the stirring main driving shaft 9 via the stirring head 15 . When the stirring main drive shaft 9 rotates, the revolving box 11 rotates integrally around the axis of the stirring main drive shaft 9 . By this turning, the stirring drive shaft 13 revolves around the center of the stirring container 3 which is the axis of the stirring main drive shaft 9 .

At the same time, the rotational driving force is transmitted from the main stirring drive shaft 9 to the stirring drive shaft 13 through the meshing of the gears inside the revolution box 11 . This rotational transmission causes the stirring drive shaft 13 to rotate about its axis.

That is, the stirring drive shaft 13 rotates and revolves around the axis of the stirring main drive shaft 9 , and the scraping blades 27 and 29 move to scrape the bottom of the stirring vessel 3 . In addition, the outer peripheral scraping blade 33 revolves together with the shaft support cylinder 19 to scrape and move the side wall of the stirring container 3 .

The bottom of the stirring vessel 3 is a direct heat transfer surface for heating, and scraping by scraping blades 27, 29 and 33 promotes heat transfer. In particular, the adhesive material on the bottom has been renewed and is highly effective in preventing scorching.

[Production of processed products]
First, raw materials of granular or lumpy solid matter and adhesive material are put into the stirring vessel 3 .

When the stirring/swirling device 5 is driven and controlled, the vane pipes 23, 25, and 31 rotate due to the rotation and revolution of the stirring drive shaft 13, and the scraping vanes 27, 29, and 33 scrape and stir. At the same time, the gas heater is operated under the control of the control box, and the heating of the stirring container 3 is controlled. The raw material in the stirring vessel 3 is heated and stirred.

When a high-melting adhesive material in a molten state, such as candy, and particulate solids are stirred and mixed by the stirring device 1, the high-melting adhesive material is attached to the scraping blades 27, 29, 33, etc. and the blade pipe 23 supporting them. , 25, etc.

At this time, even if the high-melting point adhesive material adheres to the support rod covering portion 59 of the vane pipe 23 and the scraping blade 27 and the mounting plate cover portion 63, the high-melting point adhesive material absorbs heat because of its low thermal conductivity. restrain from being caught. In addition, since the coefficient of friction of the supporting rod covering portion 59 and the mounting plate covered portion 63 is low, the adhering high-melting-point adhesive material is suppressed from growing as an adhering substance.

This action is the same for the blade pipe 25 and the support rod covering portion and mounting plate covering portion of the scraping blade 29 and the mounting plate covering portion of the scraping blade 33 .

Therefore, it is possible to prevent the grown deposits from peeling off and being mixed into the product, thereby improving the quality of the product.

In addition, the cleaning time for removing deposits from the blade pipes 23, 25, the scraping blades 27, 29, etc. after the production is finished can be shortened, and the decrease in product yield can be suppressed.

[Production of processed products]
First, raw materials of granular or lumpy solid matter and adhesive material are put into the first stirring vessel 107 .

When the first stirring unit 109 is driven and controlled, the scraping blade rotates and revolves. At the same time, the gas heater 25 is operated under the control of the control box 126, and the heating of the first stirring container 107 is controlled. In this state, the first stirring unit 109 is driven and controlled to heat and stir the raw material in the first stirring vessel 107 to produce an intermediate product.

At this time, the high-melting-point adhesive material on the vane pipe or the like is prevented from growing as an adhering matter in the same manner as in Example 1 by the supporting rod covering portion and the mounting plate covered portion of the first stirring portion 109 . , the same effect can be obtained.

Next, the heating control of the first stirring vessel 107 and the driving control of the first stirring section 109 are stopped, and the rotation of the stirring head 137 moves the first stirring section 109 to the upper side of the first stirring vessel 107 . is evacuated to

Next, by driving the hydraulic cylinder device 130, the first stirring vessel 107 is tilted toward the second stirring vessel 111 as shown in FIG.

In the state of FIGS. 6A and 6B, due to the tilting motion of the first stirring vessel 107, the high-melting and fluid intermediate material in the first stirring vessel 107 flows from the spout 179 onto the chute 175. , smoothly received from the hopper portion 161 and transferred into the second stirring container 111 .

At this time, the heating by the gas heater 25 of the first stirring container 107 is performed from the bottom side, and the temperature of the spout 179 and the chute 175 may not rise sufficiently. Therefore, if the spout 179 and the chute 175 are made of a metal such as stainless steel, the intermediate processed material, such as candy, in which the molten high-melting-point adhesive material and the particulate solid are agitated and mixed, will be cooled when it moves. try to stick to it.

However, since the spout 179 is lined with a fluororesin spout cover and the chute 175 is lined with a fluororesin chute cover, the thermal conductivity of the surface is lower than that of metal such as stainless steel. there is

Therefore, even if the high-melting-point adhesive material adheres to the spout 179 or the chute 175, the high-melting-point adhesive material is prevented from absorbing heat due to its low thermal conductivity. In addition, since the coefficient of friction of the spout cover and the chute cover is low, the adhering high-melting-point adhesive material is suppressed from growing as an adhering substance.

Therefore, it is possible to prevent the grown deposits from peeling off and being mixed into the product, thereby improving the quality of the product.

In addition, it is possible to shorten the cleaning time for removing deposits from the spout 179 and the chute 175 after the completion of production, and to suppress the decrease in product yield.

When the intermediate processed material is transferred into the second stirring vessel 111 as described above, the tilting motion of the first stirring vessel 107 is restored, and cooling water is supplied from the water supply section to the fluid jacket 171 through the water supply pipe. be. In this state, the second stirring unit is driven, and in the second stirring vessel 111, the intermediate processed material is stirred with cooling as a subsequent stirring process.

In the stirring process in the second stirring vessel 111, the intermediate processed material is stirred and rotated in the vertical direction by the stirring rotation of the scraping blades, the adhesive material coated on the solid material is cooled and solidified, and the grains or lumps are solidified. It is possible to obtain a loosened processed material.

At this time, since the stirring rotation in the second stirring container 111 is not in the horizontal direction but in the direction of gravity, the solids scraped up by the scraping blades fall in the second stirring container 111 and the surface is coated. can promote the separation of the gradually solidifying solids from each other.

When performing continuous batch production, the same operation is continuously performed.

Both the first and second agitation processing units 103 and 105 are cleaned after production is finished. In particular, in the first stirring processing section 103, it is necessary to clean the inside of the first stirring container 107 or the first stirring section 109 by removing sticky materials and solid matter.

During this cleaning, since the adhesive material is not solidified, it can be easily dissolved and removed with hot water in a short period of time.

The washing water remaining in the first stirring container 107 after washing can be drained without difficulty by tilting the first stirring container 107 toward the spout 179 as indicated by the chain line in FIG. 7(B). can.

The chute 175 is switched and set so as to be inclined downward toward the first stirring container 107 side by rotating on the rotating shaft 176 when draining water. In this state, the spout 179 of the tilted first stirring vessel 107 faces the middle of the bottom of the chute 175 .

In the state of FIGS. 7A and 7B, the wash water discharged from the first stirring container 7 hits the chute 75 from the spout 79 and is guided downward by the chute 75 to complete the discharge. Even if a small amount of sticky material adheres to the chute 75 due to the transfer of the intermediate processed material, the washing is promoted by being hit by the waste water.
