[0009]
DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1, the supply device of the present invention includes a hopper portion 10, a propulsion blade body 50 including a shaft portion 20, an inner blade 30, and an outer blade 40, and pump portions 60 and 70.
[0010]
The hopper portion 10 is for supplying raw materials such as organic wastes, and an inclined cylinder 12 formed on a tapered surface of an appropriate angle is disposed below an input port 11 whose upper surface is open, and below that. The introduction cylinder 13 is continuously provided.
[0011]
The shaft portion 20 is a rod-like body or hollow body having a circular cross section that is erected up and down substantially through the center of the taper 10, and one end is fixed to a fixing rod 21 that is laid on the hopper portion 10.
On the other hand, shaft portions 22 and 23 are formed in two stages at the tip, and support plates 24 and 25 coupled to an inner blade 30 and an outer blade 40 described later are fitted therein.
[0012]
The aspect of the shaft part 20 includes an aspect separated from an inner blade 30 described later and an aspect integrated with the inner blade 30.
The separated mode is as shown in FIG. 1, and does not form a rotation axis for the inner blade 30 described later, but acts as a reaction body of the pushing force of the inner blade 30. It is fixed to the upper and lower supports without rotating.
On the other hand, although the illustration integrated with the inner blade 30 is omitted, it is assumed that conveyance is possible due to the relationship between the inner blade 30 and the outer blade 40.
[0013]
Next, the inner blade 30 is formed into a spiral blade body having a size that occupies about a half of the space of the cylindrical body 10 that rotates while surrounding the shaft portion 20 outside the shaft portion 20. .
The rotation of the inner blade 30 is formed by supporting a connecting shaft 31 connected to the base end of the inner blade 30 with a bearing 32 and fixing it to a rotating gear 33 connected to a motor. Make it possible.
[0014]
The outer blade 40 is a blade body formed by drawing a spiral in a space sandwiched between the inner blade 30 and the inner wall surface of the cylindrical body 10, and the direction of the spiral is opposite to the direction of the spiral of the inner blade 30. It is formed so as to be oriented. The direction of rotation is configured to be both the direction opposite to the rotation of the inner blade 30 or the forward direction.
That is, if the spiral of the inner blade 30 is in the right-handed direction, the outer blade 40 is wound in the left-handed direction.
The rotation of the outer blade 40 is the same as that of the inner blade 30, and the connecting shaft 41 connected to the base end of the outer blade 40 is supported by the bearing 42 and fixed to the rotating gear 43 connected to the motor. Formed. The direction of the rotation is opposite to the direction of rotation of the inner blades, or the forward direction. That is, it is desirable that the rotation directions of the inner blade 30 and the outer blade 40 are both the same direction, or can be rotated in the opposite directions, and the number of rotations can be set freely.
Moreover, although the case where each of the inner blade 30 and the outer blade 40 is one was shown, it is possible to increase the number of blades of the same diameter to two to three by shifting the mounting position.
The propulsion blade body 50 is configured by combining the inner blade 30 and the outer blade 40.
[0015]
The inner blade 30, the outer blade 40, and the support plates 24, 25 are formed by first forming a shaft portion 22 for coupling with the inner blade 30 at the tip of the shaft portion 20, and supporting plate 24 there. And the tip of the inner blade 30 is fixed to the support plate 24 (see FIG. 7).
Next, a shaft portion 23 for coupling with the outer blade 40 is formed, and a support plate 25 is pivotally attached thereto, and the tip of the outer blade 40 is fixed to the support plate 25 (see FIG. 8). Then, the support plate 24 and the support plate 25 are combined in steps and fixed to the inner blade 30 and the outer blade 40 (see FIG. 9).
[0016]
The positional relationship between the hopper portion 10 and the shaft portion 20 and the inner blade 30 and the outer blade 40 connected to the shaft portion 20 first penetrates the inclined cylinder 12 formed on the tapered surface of the hopper portion 10 and the tip thereof. Is inserted into the introduction cylinder 13.
[0017]
In the above configuration, it is desirable to provide a slight clearance between the shaft portion 20 and the inner blade 30. Similarly, in the vicinity of the contact portion between the inner blade 30 and the outer blade 40, and the outer blade 40 and It is desirable to provide a slight clearance C between the inner wall surface of the hopper portion 10 (see FIG. 3).
[0018]
With the above configuration, the propulsion blade 50 or the like has a propulsive force of the supply, and thus functions as a supply device by itself. Therefore, it can be used alone for the supply device for items with low frictional resistance (pressure loss) such as leftovers for school lunches.
However, when the pressure is large or the pumping distance is long, the connection with the pump is effective.
[0019]
Accordingly, the pump unit will be described next. The pump includes two modes: (a) a two-arm piston type pump 60 and (b) a pumping tube type pump 70.
(A) A two-arm piston type pump 60, as shown in FIG. 4, has two suction ports 14 and 14 'formed on the hopper side, and a discharge port 15 disposed therebetween. On the other hand, a suction piston 61 and a discharge piston 62 are arranged on the pump side at the other end. The pistons 61 and 62 are slidable so that the suction port 14 is adapted to the operation of the piston. , 14 ′ and the discharge port 15 can be switched.
(B) As shown in FIG. 6, the pumping tube type pump 70 is provided with a pumping tube 74 along the inner wall of a circular frame 73 in which a suction port 71 is disposed on the upper side and a discharge port 72 is disposed on the lower side. A rotor 76 that is rotatable about a shaft 75 is disposed there, and a roller 77 that squeezes the pumping tube 74 is attached to the tip of the rotor 76.
However, the mode of the pump is not limited to this.
[0020]
In the above configuration, the propulsion blade body 50 is provided in the vertical and vertical directions. However, when the height is not desired, the propulsion blade body 50 is provided in the horizontal direction as shown in FIG. It is also possible to adopt a mode in which the hopper 10 is connected to a part of the hopper 13.
[0021]
Next, the operation of this embodiment will be described.
First, waste containing organic waste is introduced from the inlet 11 of the hopper 10, and at the same time, the motor connected to the inner blade 30 and the outer blade 40 is started.
Then, the inner blade 30 rotates through the connecting shaft 31, and similarly, the outer blade 40 starts rotating in the opposite direction to the inner blade through the connecting shaft 41 (see FIG. 2).
[0022]
Then, first, the waste thrown into the central portion of the cylindrical body 10 comes into contact with the spiral blades of the inner blade 30 rotating at the central portion, and eventually the propulsion that acts forward of the rotation of the spiral blades. It is pushed forward by force, that is, downward.
At this time, when the shaft part 20 is separated from the inner blade 30 and fixed, the waste is prevented from adhering to the blade.
That is, when the shaft and the blade are integrated, there is a risk that the viscous waste gets tangled near the shaft and does not move forward. However, in the present invention, the shaft separated from the blade acts as a reaction against the inertial force of the waste pushed forward, and plays a role of assisting the propulsion by the rotation of the waste.
[0023]
Next, since the outer blades 40 are spiral blades, they work to propel waste in the rotational direction in the same manner as the inner blades 30, but the directions of the spirals and the rotational directions are opposite, so the inner blades 30 and the outer blades. In the vicinity of the rotational contact portion 40, the waste pushed by the inner blade 30 and the waste pushed by the outer blade 40 are pushed in opposite directions.
[0024]
Considering this as a vector, a force perpendicular to the inclination of the blade acts on the spiral blade, but it acts by dividing it into a forward thrust and a lateral displacement force. And in the inner blade | wing 30 and the outer blade | wing 40, the direction of the force shifted to this horizontal direction turns into a mutually opposite direction, and it becomes a form which mutually presses.
[0025]
Therefore, when the two forces are combined, the collision with each other does not cause the waste to rotate idly, but forms a reaction relationship with respect to the action and promotes the action of pushing the waste forward, that is, vertically downward.
[0026]
Furthermore, the reaction of the inner wall surface is also promoted between the outer blade 40 and the inner wall surface of the cylindrical body 10.
[0027]
As a result, even in the organic waste having a relatively high viscosity, forces in different directions work in each direction in the cylindrical body 10, so that they cooperate with each other in the viscosity. It prevents idle rotation based on consistency, and can act as a driving force in the extrusion direction.
[0028]
Furthermore, in the vicinity where the inclined cylinder 12 of the hopper 10 intersects with the inner blade 30 and the outer blade 40, it becomes an obstacle when the organic waste that has flowed down contains, for example, a lump, but due to gravity, It is ruptured by being sandwiched between the inclined cylinder 12 and the outer blade 40 and further broken by giving a difference in the rotational speed of the outer blade 40 and the inner blade 30. By rotating the inner blade 30 reversely in conjunction with switching between suction and discharge of a piston type pump and pumping tube type pump 70 which will be described later, crushing and kneading are performed, viscosity is increased, and pressure feeding is facilitated.
[0029]
Next, in order to operate the pump, in the case of the two-arm pump 60, first, the suction piston 61 and the discharge piston 62 are operated to start suction and discharge from the suction port 14 and the discharge port 15, and supply by pump suction is performed. Start (see FIG. 5A). When the suction from the suction port 61 is completed, the suction piston 61 and the discharge piston 62 are slid and connected to the hopper side discharge port 15 and the suction port 14 ′ (see FIG. 5B). Then, suction and discharge are started and repeated (see FIG. 5C).
At this time, as described above, a strong propulsive force is applied to the propulsion blade body 50. Therefore, when the piston moves backward and starts to suck, even the sludge dewatered cake with a high viscosity soil is prevented from flowing in and reliably pressurized. Insert the conveyed product into the section. In addition, even when solid materials such as potatoes, radishes, and nanban are mixed, they are reliably inserted while being crushed to about 1/3 of the front of the pressurizing section, enabling continuous long-distance feeding. .
[0030]
Next, in the case of a pumping tube type pump, as shown in FIG. 6, the inlet tube 13 on the hopper side is connected to the suction port 71 on the upper side of the pump. When the rotary rotor 76 is rotated, the roller 77 connected to the rotor 76 handles the pumping tube 74 to advance the contents and discharges it from the discharge port 72.
Also at this time, like the above-mentioned two-arm piston type pump, the strong propulsive force of the propulsion blade body 50 prevents the inflow of air even in the sludge dewatering cake with a high viscous soil, and reliably inserts the conveyed product into the pressurizing unit, In addition, even when solid matter such as potatoes, radishes, and nanban are mixed, they are reliably inserted while being crushed, enabling continuous long-distance feeding.
[0031]
In addition, when the shaft part 20 and the inner blade 30 are integrated, there is no effect of preventing the entanglement near the shaft described above. A strong vertical driving force can be exerted in cooperation with the blades 40.
[0032]
Further, when the propulsion blade body 50 is provided in the horizontal direction and the hopper 10 is connected to a part of the introduction cylinder 13, the action of gravity in the vertical direction is reduced, but the inner blade 30 and the outer The interaction with the blades 40 and the action by the pumps 60, 70 can be expected as well.
[0033]
The present invention is mainly aimed at supplying highly viscous organic substances, etc., but is not limited to this as long as it produces strong propulsion, crushing, kneading action, etc. on the same principle, Widely applicable.
[0034]
【The invention's effect】
The apparatus of the present invention based on the above configuration is subjected to strong propulsion, crushing, kneading and other actions when supplying waste containing viscous substances, which has been difficult to accurately convey in the past. In addition, since it is realized by a relatively simple mechanism, it has an excellent effect that it can be applied to organic waste and other uses.
