Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method of stirring and mixing a plurality of kinds of powders, and adding a liquid such as a binding liquid to the plurality of kinds of stirred and mixed powders to combine the powders.
For example, the present invention relates to an improvement in an agitation type granulator for granulating fine granules used for pharmaceuticals and the like.

[0002]

2. Description of the Related Art Conventionally, an agitation type granulating apparatus used for granulating fine granules used for pharmaceuticals or the like is, for example, mounted horizontally on a mounting frame formed by framed angle iron or the like. Mounted and fixed, a bottomed cylindrical granulation tank having an inlet at the top and a discharge port at the lower side, respectively, and a stirring blade arranged at the bottom of the granulation tank and rotated by driving an electric motor, A stirring blade is disposed on a side wall surface of the granulation tank at right angles to the stirring blade and is rotated by driving an electric motor.

[0003] In the agitation type granulator having the above structure, when granulating fine granules, first, a predetermined amount of a plurality of types of powders are charged into a granulation tank through a charging port. By rotating and driving the stirring blade and the crushing blade, the plurality of types of powder are stirred and mixed. After the powder has been stirred and mixed for a predetermined time, subsequently, a binder solution is charged and added into the granulation tank, and the plurality of types of powder are bound by the binder solution, and the powder is rotated by rotating the stirring blade. The plurality of types of powders are granulated into particles having a predetermined particle diameter and sized by a dynamic / consolidation action and a shear action caused by rotation of the crushing blades.

[0004] After the granulation of the granules is completed, the discharge port is opened and the stirring blade is rotated, and the granulated granules are utilized by utilizing the scraping action and centrifugal force of the rotation of the stirring blade. Was discharged from the outlet to the outside of the granulation tank (e.g., a container).

When the inside of the granulation tank is washed, washing water is sprayed into the granulation tank from a charging port with a hose or the like while the discharge port is opened, and granulated using a sponge scourer or the like. In addition to washing away the particles and powder adhering to the inside of the grain tank and the like, the washing water is discharged from the outlet.

[0006]

However, in the stirring type granulator having the above-mentioned structure, when the granulated granules are discharged to the outside from the discharge port of the granulation tank, the granules in the granulation tank are discharged. When the amount is large, the particles can be relatively easily discharged by the rotation of the stirring blade, but when the amount of the discharged particles decreases, the rotation of the stirring blade alone can discharge the particles. In such a case, the rotation of the stirring blade is temporarily stopped, and the particles are discharged from the discharge port while collecting the granules manually using a brush or the like. The work efficiency was extremely poor because the granules collected in the above were discharged by rotating the stirring blade again.

When the inside of the granulation tank is washed, the water (washing water) around the discharge port can be relatively easily discharged and removed from the discharge port, but the granulation tank is attached to the mounting frame. Moisture (washing water) that exists (adheres) at a location away from the outlet because it is fixed horizontally to the
Is likely to stay in the granulation tank (corner etc.)
It is difficult to smoothly and satisfactorily discharge and remove the water (that is, the drainage state is poor). As a result, the water must be forcibly discharged and removed manually, which is very troublesome.

The present invention has been made in view of the above-mentioned various problems, and has been made to expedite the discharge of granules and the discharge and removal of water in a granulation tank after washing.
An object of the present invention is to provide an agitation-type granulation apparatus that can be easily performed.

[0009]

In order to solve the above-mentioned problems, an agitation type granulator according to the present invention has a powder inlet at an upper portion and a granule outlet at a lower side surface. A cylindrical granulation tank with a bottom, a stirring blade rotatably arranged at the bottom of the granulation tank, a driving means for rotating and driving the stirring blade, and a side wall surface of the granulation tank orthogonal to the stirring blade. A crushing blade rotatably arranged in such a manner, an electric motor for rotationally driving the crushing blade, and a tilting means for tilting the granulation tank at a predetermined angle with its discharge port side obliquely downward. It is characterized by having done.

[0010] Further, the tilting means includes a support portion rotatably supporting one end side of the granulation tank adjacent to the discharge port,
A cylinder device for tilting the other end side of the granulation tank at a predetermined angle around the support portion, and a stretchable and tiltable connecting means for drivably connecting the stirring blade and a driving means. It is characterized by the following.

Further, the connecting means has a hollow cylindrical connecting cylinder, a cylindrical cylindrical section having a bulb section at a distal end, and a base end inserted and fixed to one end side of the connecting cylinder. 1 connecting shaft and a spherical portion at the distal end, and can be advanced to and retracted from the other end of the connecting cylinder with a compression spring inserted between the base end and the first connecting shaft. A second connecting shaft having a polygonal shape inserted into the first and second connecting shafts, and a first and a second joint member which are tiltably connected to the ball joints of the first and second connecting shafts. (1) The driving means and the stirring blade are drivably connected by fixing the second joint member to the driving means and the stirring blade.

According to the present invention, since the granulation tank can be tilted forward by a predetermined angle by the cylinder device with the support portion provided on the discharge port side as a center, the discharge of water during the discharge of the granules and the washing is performed.
Removal can be performed smoothly and easily. Further, since the stirring blade and the driving means disposed at the bottom of the granulation tank are connected and held via the expansion and contraction and tiltable connection means, the tilting movement of the granulation tank can be performed smoothly, In addition, even if the granulation tank is inclined, the driving force from the driving means can be reliably transmitted to the stirring blade, whereby the stirring blade can be smoothly and satisfactorily rotated.

Next, the operation of the agitation type granulator 1 of the present invention will be described. The operation of the agitation type granulator 1 is performed based on a control program preset in a controller (not shown).

First, when a plurality of types of powder are charged into the granulation tank 3 for granulating fine granules, for example, the cylinder device 23 is driven to retract the piston rod. The lid 20 is rotated clockwise from the state shown by the solid line in FIG. 1 around the support shaft 20a as shown by the two-dot chain line to open the insertion port 3a.

Stop rotation of 18. The granulation time may be determined based on the result of sampling (sampling) the granules at regular intervals, the granulation process obtained from the torque applied to the stirring blade 8 and the fluctuation of power consumption, and the like.

Next, the granules having been granulated are placed in a granulation tank 3.
The case of discharging from inside will be described. Granulation tank 3
When discharging from the inside, first, the cylinder device 24c of the discharging means 24 is driven to retract the closing body 24a attached to the tip of the piston rod to the left in FIG.

When the granulating tank 3 is tilted, the connecting means 10 is connected to the ball sections 12a and 13a by
Since it tilts in a predetermined direction (rightward direction in FIG. 6 for the bulb portion 12a and leftward direction in FIG. 6 for the bulbous portion 13a),
The tilting operation of the granulation tank 3 is not hindered at all.

Further, even if the dimensions between the joint members 15 and 16 change due to the tilting of the bulb sections 12a and 13a, the second connecting shaft 13 uses the elastic force of the compression spring 14 to connect the connecting cylinder. By moving out of 11, the connection between the drive shaft 6 and the output shaft 9c of the reduction gear 9b is maintained.
Even when the granulation tank 3 is inclined, the stirring blades 8 can be satisfactorily rotated to discharge the granules.

Further, the second connecting shaft 13 is connected to the connecting cylinder 11
The second connecting shaft 1
Since the inner peripheral surface of the connection tube 3 itself and the upper portion of the connection tube 11 into which the connection shaft 13 is inserted are formed in a polygonal shape, an idling phenomenon occurs between the second connection shaft 13 and the connection tube 11. The deceleration output from the reduction gear 9b is reliably transmitted to the stirring blade 8.

When the discharge of the granules is completed, the closing device 24a is moved rightward in FIG. 6 by driving the cylinder device 24c of the discharge means 24 to close the discharge port 3b as shown in FIG. , Cylinder device 17 constituting tilting means
To return the granulation tank 3 to a horizontal state (original position) as shown in FIG. 1 around the support shaft 5c of the support portion 5. Thereafter, when granulating and discharging the granules, the above operation may be repeated.

Next, the case where the inside of the granulation tank 3 is cleaned will be described. When cleaning the inside of the granulation tank 3, first, the lid 20 is rotated by driving the cylinder device 23 to open the charging port 3a (see the two-dot chain line in FIG. 1), and the stirring blade 8 and the crusher The blades 18 are removed from the drive shaft 6 and the output shaft (not shown) of the electric motor 19, respectively.

Subsequently, as shown in FIG.
By driving the cylinder device 24c of No. 4 to retreat the closing body 24a to open the discharge port 3b, and by driving the cylinder device 17 constituting the tilting means, the granulation tank 3 is connected to the support shaft of the support portion 5. The outlet 3b is inclined at a predetermined angle around the center 5c so that the outlet 3b faces obliquely downward.

Thereafter, the washing water is sprayed into the granulation tank 3 from the opened inlet 3a using a hose or the like, and adheres to the inside of the granulation tank 3 or the lid 20 using a sponge scourer or the like. The washing water is discharged from the discharge port 3b while washing out the granules and powders.

As a result, the washing water injected into the granulation tank 3 is successively inclined such that the granulation tank 3 is inclined with the discharge port 3b side obliquely downward. Since the powder and the like adhering to the water are washed out and discharged to the outside from the discharge port 3b, moisture (wash water) at a position away from the discharge port 3b does not stay in the granulation tank 3 without any stagnation.
It is possible to discharge and remove (water drain) satisfactorily, and as a result, only a simple wiping operation for drying is required.

Although the present invention has been described with reference to the example in which the binding liquid is dropped and poured into the granulation tank from a funnel-shaped nozzle attached to the lid, the binding liquid is sprayed using a spray nozzle. You may make it spray and add to several types of powder. In addition, when discharging the granules, an example has been described in which the granulation tank is tilted in the middle of the discharge, but the granulation tank may be tilted from the time when the discharge is started.

Further, in the washing of the granulation tank, an example will be described in which the discharge port is opened, and washing is performed by spraying washing water into the granulation tank in a state where the granulation tank is inclined. However, for example, after washing water is poured into the granulation tank with the outlet closed, and washing is performed using the rotation of the stirring blade, the outlet is opened, and the granulation tank is tilted. Then, the cleaning water may be discharged.

[0046]

As described above, the agitation type granulator of the present invention is provided with the tilting means for tilting the granulation tank at a predetermined angle, so that the discharge of the granules and the cleaning of the granulation tank are performed. In addition, the discharge can be performed in a state in which the discharge port is inclined obliquely downward, and as a result, the discharge of the granules and the cleaning of the granulation tank can be performed quickly, easily, and in a short time.

Further, the tilting means includes a support portion rotatably supporting one end of the granulation tank, a cylinder device provided on the other end side of the granulation tank, a driving means, and a stirring device. It is constituted by an expandable and contractible connecting means for connecting the blades drivably, and by driving the cylinder device, the granulation tank can be easily moved to the discharge port side around a support shaft of a support portion. It can be inclined in an obliquely downward state.

In addition, when the granulation tank is inclined, the expandable and contractible and tiltable connecting means tilts in a predetermined direction at the ball sections provided on the first and second connecting shafts.
The tilting operation of the granulation tank is not hindered at all, and the second connecting shaft extends out of the connecting cylinder by a required size by the elastic force of the compression spring with the inclination of the granulating tank. Since the connection between the driving means and the stirring blade is maintained,
The output (rotation) from the driving means is reliably transmitted to the stirring blade even if the granulation tank is inclined.

Further, the second connecting shaft has a polygonal shape on the base end side, and the inner peripheral surface on the upper side of the connecting cylinder into which the second connecting shaft is inserted is also formed in a polygonal shape. Therefore, even if the second connection shaft is configured to be able to advance and retreat with respect to the connection tube, no idling phenomenon occurs between the connection tube and the second connection shaft, and the drive is reliably performed. Force (rotation) can be transmitted.
