Description

Blender and blender pump

The present invention relates to a blender pump capable of transporting an object to be transported and mixing with sub-materials, and a blender used therefor.

Conventionally, for example, a continuous candy manufacturing apparatus described in Patent Document 1 is known as a transfer apparatus that transfers and mixes an object to be transferred. The candy manufacturing apparatus disclosed in Patent Document 1 transfers a high-viscosity sugar solution stored in a tank to a supply pipe by a sugar liquid pump, and the sub-material sent out by the sub-material pump in the middle of the supply pipe. The combined sugar solution and the auxiliary material are mixed by an in-line static mixer and then discharged to the concentration tank.

Japanese Patent Laid-Open No. 7-289168

By the way, although the candy manufacturing apparatus described in the patent document described above includes a static mixer, this static mixer can be stirred relatively well when a low-viscosity fluid is passed at high speed, and high mixing efficiency can be obtained. However, when passing a highly viscous fluid, it is difficult to generate a turbulent fluid flow in the mixer, and there is a problem that the mixing efficiency is greatly reduced.
On the other hand, in order to handle foodstuffs in particular, it is desirable that the area in contact with the foodstuffs is small in terms of cleaning and hygiene after work. Therefore, it is preferable that the supply piping from the sugar solution pump to the static mixer is as short as possible, and there is no ideal at all. In addition, since the sugar liquid pump and the static mixer are separately and independently provided with a supply pipe between them, there is a problem that a large total installation space must be taken.

The present invention has been made in view of the above-described conventional problems, and a blender-equipped pump capable of performing transfer and mixing of an object to be transferred and sub-materials in a single unit without taking up a large installation space, and The purpose of this is to provide a blender used for it.

In order to achieve the above object, a blender according to the present invention is connected to a discharge port of an external pump unit, and has a secondary material input part formed in a cylindrical shape having an input port for taking in a secondary material from the outside. A cylindrical blender casing having one end connected to the auxiliary material charging portion and a discharge port for discharging the transferred object and the secondary material to the outside of the pump; A mixing rotating shaft that is arranged along the cylinder center direction of the blender casing and is rotationally driven by being connected to an external rotation driving source, a stirring plate member provided on an outer peripheral surface of the mixing rotating shaft, and A passage portion formed between the stirring plate member and the inner peripheral surface of the blender casing or on the stirring plate member itself so as to allow the transferred object to pass in the transferred object transfer direction. A stirring plate member of the blender unit, wherein the material to be transferred and the sub-material are transferred to the blender casing when the mixing rotation shaft is rotated in a specified rotation direction. The mixing rotary shaft is inclined and arranged so as to be pushed back toward the one end side.

In the above configuration, the other end portion of the blender casing is connected to a blender bearing portion that can pivotally support one end portion of the mixing rotating shaft in a cantilevered manner, and One end portion is connected to a blender rotary drive source via the blender bearing portion.

Furthermore, in each of the above-described configurations, a single mixing rotating shaft is used as the mixing rotating shaft of the blender section.

Further, in each of the above-described configurations, a protruding portion that protrudes in a direction facing the connection port is provided on a surface on the connection port side of the stirring plate member.

In addition, the blender-equipped pump according to the present invention includes a pump casing having an intake port for taking in the object to be transferred and a discharge port for discharging the transferred object, and the intake port provided in the pump casing. A pump unit having a pressurizing motion member that pressurizes an object to be transferred from the pump and sends it to the discharge port, and the discharge port of the pump casing of the pump unit is connected to the connection port of the auxiliary material input unit in the blender It is characterized by being.

6. The blender-equipped pump according to claim 5, wherein the pump portion accommodates the pair of pump screws that are pressurizing motion members that rotate in a non-contact screwing manner and the pair of pump screws in a non-contact manner. A chamber is formed in the casing, and the pump casing forms a pump chamber by the pair of pump screws and the storage chamber, and one end portions of the pair of pump screws can be pivoted in a cantilevered manner. A bearing portion for the pump to be supported is connected to one end portion of the pump casing, and one end portion of a pair of rotating shafts arranged coaxially with each pump screw is respectively connected to the free end of each of the pair of pump screws. The stirring blades are provided on the outer peripheral surfaces of the pair of mixing rotary shafts, and are connected to the other end of the pump casing. One end of a blender casing that accommodates the pair of mixing rotating shafts is connected, and a blender casing between the pump screw and the stirring blade is used to introduce auxiliary material from outside the pump into the pump casing. A sub-material input unit having a input port is provided, and a discharge port for discharging the transferred object and the sub-material out of the pump is provided in the blender casing on the floating end side of the mixing rotating shaft. It is what.

Further, in the above configuration, the stirring blade plate provided on the outer peripheral surface of each of the pair of mixing rotating shafts has a spiral shape opposite to the spiral direction of the pump screw connected to each mixing rotating shaft. The agitation blades of the pair of mixing rotary shafts are arranged so as to be able to rotate in a non-contacting manner so that they can pass through each of the agitation blades. The part is formed so as to penetrate in the transfer direction of the transferred object.

Further, in the above configuration, the through portion is formed by being cut out from the outermost peripheral surface in the radial direction of the rotation axis of the stirring blade plate toward the rotation axis.

According to the blender according to the present invention, it is composed of the sub-material input part and the blender part, and the stirring plate member of the blender part is arranged so as to be inclined with respect to the axis of the mixing rotation shaft. When the mixing rotation shaft is rotated in a specified rotation direction, the transferred object and the auxiliary material are pushed back toward one end of the blender casing. In addition, since the transferred object and the auxiliary material can move in the transfer direction through the passage portion, the transferred object and the auxiliary material are efficiently transferred while repeating the pushing back by the stirring blade plate and the passage through the passage portion. Uniform mixing is possible.

In addition, the mixing rotating shaft of the blender unit is configured independently of the pump unit, and one end of the mixing rotating shaft is connected to the blender rotation drive source via the blender bearing unit. Therefore, the mixing ability of the blender section can be adjusted independently of the transfer ability of the pump section. Thereby, for example, when the transported object and the auxiliary material are not easily mixed, or even when the ability of the blender part is inferior to that of the pump part from the beginning, the rotational speed of the mixing rotating shaft of the blender part is increased. Thus, sufficient mixing can be performed.

Furthermore, if a single rotating shaft for mixing is used in the blender section, a simpler and more compact configuration can be realized. In particular, when the mixing rotary shaft is driven separately from the pump unit, sufficient mixing can be achieved by increasing the number of rotations of the mixing rotary shaft even if the mixing rotary shaft has a low mixing capacity. Ability can be gained.

Further, in the case where the projecting portion protruding in the direction facing the connection port is provided on the surface on the connection port side of the stirring plate member, when the stirring plate member rotates and pushes back the transferred object and the auxiliary material. Further, there is no problem that the transferred object and the auxiliary material slide on the surface on the connection port side of the stirring plate member and lose the pushing back force. Therefore, the material to be transferred and the auxiliary material can be mixed without waste using the pushing-back force received from the surface on the connection port side of the stirring plate member.

Moreover, in the pump with a blender in which the discharge port of the pump casing of the pump unit is connected to the connection port of the auxiliary material input unit in the blender, the transferred object and the auxiliary material can be transferred and stirred and mixed with a single device. .

Further, a stirring blade plate portion is provided on the outer peripheral surface of the rotating shaft for mixing that is coaxially connected to the pump screw, and the auxiliary material feeding portion between the pump screw and the stirring blade plate portion is used for the auxiliary material. In a blender-equipped pump in which an inlet is provided and an outlet is provided in the blender casing on the floating end side of the rotating shaft for mixing, a single rotational drive source can transfer and mix the material to be transferred and the auxiliary material. Of course, since the pump part and the blender part are adjacent to each other, there are no pipes between them, so it is not necessary to clean the pipes after work, which is also suitable for hygiene. It is particularly preferable when handling foodstuffs. At the same time, since it has a compact configuration, it can be installed without taking up much space.

Furthermore, each stirring blade plate part of the pair of mixing rotating shafts is provided in a non-contact manner and arranged in a spiral direction opposite to the spiral direction of the pump screw, and each stirring blade plate part has a through portion. In what is formed, the material to be transferred and the sub-material can be mixed efficiently by the pushing back action by the plate surface of the stirring blade plate part and the passing action of the penetration part. In other words, a blender-equipped pump having a non-contact pump screw and having both a pump function and a blender function could be provided.

In addition, in the case where the penetration part is formed by cutting away from the outermost peripheral surface in the radial direction of the rotation axis of the stirring blade plate part toward the rotation axis, the penetration part can be easily manufactured by a cutting machine. The through area can be made larger than that of a circular hole. Moreover, this penetration part is opened facing the internal peripheral surface of a pump casing. Thereby, since a passage passage becomes large and the passage amount of the mixture increases, the amount of stirring can be increased, and the mixing efficiency can be further increased.

stirring blade portions

34a, 34b are projected outward in the rotational axis radial direction. These stirring

blade portions

34a and 34b are both provided in a spiral arrangement opposite to the spiral direction of the pump screws 7a and 7b connected to the mixing

rotary shafts

29 and 29. The pair of stirring

blades

34a and 34b are formed so as to be able to rotate by screwing in a non-contact manner. In addition, a plurality of through portions (examples of passage portions) 35, 35, 35,... Capable of passing the material to be transferred Q are respectively provided in the

stirring blade portions

rotary shafts

29 and 29 are rotated in the prescribed rotation directions (arrows Ra and Rb) with respect to the axis Xa and Xb of the mixing rotary shaft 29. The material to be transferred and the auxiliary material are set in such a direction that they can be pushed back toward one end of the blender casing 3. That is, the blender casing 3, the mixing

rotary shafts

29 and 29, the stirring

plate members

34 a and 34 b, and the penetrating portion 35 constitute the blender portion 53, and the auxiliary material charging portion 52 and the blender portion 53 constitute the blender 101, The pump bearing unit 5, the pump unit 51, and the blender 101 constitute a blender-equipped pump 1.

Next, the operation of the blender-equipped pump 1 configured as described above will be described. Here, an example is shown in which a “molten candy material” having a relative viscosity of 50 Pa · s (@ 100 ° C.) is used as the high-viscosity transfer object Q. The molten candy material is a sugar liquid obtained by heating and boiling raw materials such as sugar and starch syrup. Then, the auxiliary material is input from the

input ports

23, 24 and 25. For example, heated buttered butter is press-fitted by pump power or the like from the charging port 23, and heated and melted chocolate is press-fitted by pump power or the like from the charging port 24. It shall be press-fitted with pump power.

First, when the pump screw 7a is rotated in one direction (the direction of arrow Ra in FIG. 7B) by the rotational drive of the motor M, the pump screw 7b to which power is transmitted via the synchronous gears 13a and 13b is reversed (see FIG. 7 (b) in the direction of arrow Rb). The rotational speed of the pump screws 7a and 7b is, for example, 100 to 1000 rpm. Then, the transferred object Q in the hopper enters the pump chamber 6 from the hopper through the pipe portion 21 and the intake port 18 of the pump casing 2. The transferred object Q that has fallen into the pump chamber 6 is pumped in the direction of the black arrow F by the pump action of the pump screws 7a and 7b, and passes through the connection port 14 of the blender casing 3 from the discharge port 55 of the pump casing 2. Then, it is transferred toward the

blender units

28a and 28b in the blender casing 3. Here, the transported material Q was joined together with the melted butter pressed from the charging port 23 of the auxiliary material charging unit 52, the molten chocolate pressed from the charging port 24, and the molten fat and oil pressed from the charging port 25. Thereafter, both arrive at the

blender units

28a and 28b.

As shown in FIG. 7, the combined product Q, melted butter, melted chocolate, and melted fat and oil are on the upstream side (connection port 14) of the

stirring blade portions

34 a and 34 b of the

blender units

28 a and 28 b. And is moved in the push-back direction or the rotational axis circumferential direction as indicated by arrows ga and gb. On the other hand, a part of the merged material passes through the through

portions

35, 35, 35,... As shown by the arrow f without contacting the plate surfaces of the

stirring blade plates

34 a, 34 b, and the next stage plate. Reach the plane. Then, the merged material pushed back on the plate surface and the merged material that has passed through the through

portions

35, 35, 35,... The mixing action by such pushing back movement and passing movement is repeated, and the transferred object Q and the auxiliary material are efficiently and reliably mixed to form a mixture. The pushing back force by the plate surfaces of the

stirring blade portions

34a, 34b is not so large, the gap between the

stirring blade plates

34a, 34b, and the inner peripheral surface of the

stirring blade plates

34a, 34b and the blender casing 3 Since the gap between 3A is sufficiently large, the mixture can move in the

blender units

28a and 28b by the transfer force generated by the pumping action of the pump screws 7a and 7b, and is discharged from the discharge port 19 after being sufficiently mixed. The mixture discharged from the discharge port 19 is accommodated in a receiving container, then molded in a mold, and allowed to cool to become a candy product.

As described above, according to the blender-equipped pump 1 of this embodiment, the transferred object Q, which is a fluid, has a gap G between the pump screws 7a and 7b, and the

pump screw

7a or 7b and the storage chamber 52. Since it cannot pass through the gap H with the inner peripheral surface 2A, it is pumped under the pump action of the pump screws 7a, 7b. At this time, since the pump screws 7a and 7b and the inner peripheral surface 2A of the pump casing 2 are not in contact with each other, no shear force is applied to the transferred object Q without generating metal wear powder. That is, food, medical products, etc. can be transported without alteration. The transferred object Q discharged from the pump screws 7a and 7b through the discharge port 55 can reach the

blender units

28a and 28b after joining with the auxiliary material from the input ports 23 to 25. The combined product is efficiently stirred and mixed by the

blender units

28a and 28b. That is, it is possible to perform both the transfer of the transfer object Q and the auxiliary material and the stirring and mixing with one unit.

And since the penetration part 35 is a notch part notched from 34 A of outer peripheral surfaces, it can manufacture easily using a cutting machine and can take a large penetration area compared with penetration parts, such as a circular hole. Thereby, since the passing amount of the mixture becomes large, the amount of stirring can be increased, and the mixing efficiency can be further increased.

In addition, in said Embodiment 1, although the penetration part notched toward the rotating shaft center was illustrated from the outer peripheral surface of the rotating shaft radial direction outermost part of the stirring blade board part, this invention is not limited to it.
