Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a particle processing apparatus used for the purpose of particle processing in the fields of manufacturing pharmaceuticals, agricultural chemicals, foods, electronic materials, chemical products, etc., and more specifically, granulating and coating various raw material particles. The present invention relates to a device for improving the added value of powder particles by performing particle processing such as.

[0002]

2. Description of the Related Art As a device for performing processing such as granulation and coating on raw material powder particles, a number of particle processing devices called centrifugal tumbling flow type have been conventionally proposed. In these devices, a circular rotary disk that horizontally rotates is provided in the lower part of a cylindrical processing container, and a gas flow in the vertical direction is mainly generated from a ring-shaped gap formed between the rotary disk and the processing container. The gist is the point of ejection.

The operation of this apparatus will be described in detail. The powder particles supplied into the processing container move in the radial direction while rolling on the rotary disk due to the centrifugal force generated by the rotation of the rotary disk. Next, the particles are appropriately dried while being blown up by an ascending air flow passing through the ring-shaped gap and ascendingly flown along the inner diameter surface of the processing container, and eventually fall toward the vicinity of the center in the processing container. In this way, a circulating flow in which rolling and flow are regularly repeated is performed. During such rolling / flowing of particles, a binder nozzle or a coating liquid is sprayed from a spray nozzle provided at a predetermined position in a processing container to perform processing operations such as granulation / coating of particles.

As an example of a device of the same type, Japanese Patent Publication No. 6-16
827 (Japanese Patent Laid-Open No. 62-68536) and Japanese Patent Publication No. 6-187 (Japanese Patent Laid-Open No. 62-68535) disclose a device having rotating disks arranged in multiple layers at predetermined intervals via an annular ventilation member. Is disclosed. This device ejects gas radially outward through an annular ventilation member, and the action of this gas flow and the centrifugal rotation for rotation of the turntable cooperate with each other while pressing the particles toward the inner wall of the processing container. Particle processing is performed.

[0005]

By the way, the centrifugal rolling flow type processing apparatus is mainly used for rolling motion due to surface shearing which particles receive when rolling on a rotating disk, and is blown through a ring-shaped gap. The particles are processed by utilizing the flow action of the rising gas flow. Therefore, in developing the processing apparatus, it is important to realize an optimal rolling motion state in which the rolling motion and the flow action that are optimum for the processing conditions are repeated.

Here, in order to adjust the flow action by the rising gas flow, the flow rate of the rising gas flow may be increased or decreased. on the other hand,
In order to adjust the rolling motion of the rotary disk, the area of the rolling portion on the rotary disk, the rotation speed, and / or the flow rate of the gas flow ejected in the radial direction may be adjusted. What is important here is to secure a rolling surface for imparting rolling motion.

However, Japanese Patent Publication No. 6-16827 and Japanese Patent Publication No. 6-1
In No. 87, almost no consideration was given to the role of assisting rolling, and multiple gas injections were made through the gaps between the multi-layered turntables. Therefore, while the inside of the container becomes fluid,
Regular circulation is difficult to carry out. Further, in this publication, a vertical gas flow path blown through between the rotary disk and the container and a radial gas flow path blown through the annular ventilation member are connected to the same gas chamber located under the rotary disk. Therefore, the flow rate of gas flowing through both gas flow paths cannot be adjusted independently. For this reason, it is impossible to independently adjust the rolling operation by the rotating disk and the flow action by the rising gas flow, and it is difficult to obtain an optimum rolling flow state.

On the other hand, the applicant of the present invention, in order to surely prevent cross-contamination of particles and to further activate the flow state of particles, directly below the ring-shaped gap, facing the ring-shaped gap. Disclosed is a particle processing apparatus in which a ring-shaped duct having an opening is provided, and a lower nozzle is attached to the ring-shaped duct in a tangential direction and in the same direction as the rotating direction of a turntable (Japanese Patent Application No. 4-249380). issue).

However, this device has a problem when the container is scaled up or down. That is, if the diameter of the container is changed while keeping the width of the ring-shaped gap constant, the area of the rotating disk is proportional to the square of the equivalent diameter of the container, while the area of the ring-shaped gap is the square of the equivalent diameter of the container. Proportional to. Therefore, a large difference occurs between the rolling operation change amount and the flow action change amount, and the optimum flow rolling state cannot be obtained as it is. From such a point, the conventional apparatus has a problem that a great amount of labor is required for determining the dimensions of the container and the turntable when scaling up or the like.

In view of the above, the present invention is directed to a particle processing apparatus capable of adjusting the circulating flow of a particle group to an optimum state suitable for the purpose of particle processing, while ensuring a rolling operation area where there is almost no flow action due to a gas flow. For the purpose of providing.

[0011]

In order to achieve the above object, the present invention has a substantially cylindrical processing container and a turntable that horizontally rotates in the vicinity of the bottom of the processing container, and rotates from outside the system. The gas flow supplied below the disk is jetted upward from a ring-shaped gap formed between the outer diameter surface of the rotary disk and the inner diameter surface of the processing container facing the rotary disk, and this rising gas flow and the rotary disk In a device for performing particle processing such as granulation and coating by causing the particles in the processing container to rotatively flow by a synergistic effect with the rotating motion of In addition to securing an operating area, a jet outlet is provided between the raised portion and the upper surface of the turntable toward the outer diameter side, and the flow rate is independent of the gas flow introduced into the ring-shaped gap at the jet outlet. It was decided to connect the adjustable air duct.

A part of the gas flow introduced into the ring-shaped gap may be diverted to the air guide passage.

An elevating member is disposed below the rotary disk to form an air guide path between an upper surface of the elevating member and a lower surface of the rotary disk, and the air guide path is provided through a through hole provided in the rotary disk. Alternatively, the width of the air guiding passage may be changed by raising and lowering the elevating member to adjust the gas flow rate of the air guiding passage.

A gas supply system of another system independent of the gas flow introduced into the ring-shaped gap may be connected to the air guide passage.

Immediately below the ring-shaped gap, a ring-shaped duct having an opening facing the ring-shaped gap is provided, and the ring-shaped duct is directed tangentially and in the same direction as the rotating direction of the rotary disk. An airflow inlet for introducing air may be provided.

[0016]

By providing a raised portion having an appropriate skirt in the central portion of the turntable, particles can be given a rolling action on the outer peripheral surface of the raised portion. Furthermore, an ejection port for ejecting gas in the radial direction of the container is provided between the lower surface of the raised portion and the upper surface of the turntable. Rolling flow can be exerted on the received particles by the cooperation of the rotational movement of the turntable and the gas flow. If a gas flow path whose flow rate can be adjusted independently of the gas flow (rising gas flow) introduced into the ring-shaped gap is connected to the jet port, the radial gas flow adjusted to the optimum flow rate can be jetted. It is possible to realize an ideal rolling flow state in cooperation with the rising gas flow.

By dividing a part of the gas flow introduced into the ring-shaped gap in the air guide passage, it is possible to obtain two kinds of gas flows, an ascending gas flow and a radial gas flow, with a single gas flow supply source. You can

An elevating member is disposed below the rotary disk to form an air guide path between the upper surface of the elevating member and the lower surface of the rotary disk, and the air guide path is provided through a through hole provided in the rotary disk. When the width of the air guide passage is changed by the elevating operation of the elevating member, the flow passage area changes. Therefore, the flow rate of the radial gas flow can be adjusted.

If a gas supply system of a separate system independent of the gas flow introduced into the ring-shaped gap is connected to the air guide passage, the flow rates of the rising gas flow and the radial gas flow can be adjusted completely independently of each other. Therefore, the optimum flow rolling state can be easily realized.

Immediately below the ring-shaped gap, a ring-shaped duct having an opening facing the ring-shaped gap is provided, and the ring-shaped duct is directed tangentially and in the same direction as the rotation direction of the rotary disk. If an airflow inlet for introducing air is provided, particles will not fall into the ring-shaped duct due to the cyclone effect, and the gas flow entering the container through the ring-shaped gap will become a swirl flow and rise in the processing container. .

That is, according to the present invention, it is important for particle processing by adjusting the shape of the ridge, the gas flow from the jet port and the gas flow from the ring-shaped gap to optimum values.
Optimal circulation flow of rolling-rolling flow-flow-rolling-rolling flow -... can be easily realized.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the device of the present invention will be described below with reference to FIGS.

FIG. 1 is a sectional view of a particle processing apparatus according to the present invention. However, in FIG. 1, the exhaust equipment, the particle supply port and the particle discharge port, etc. are omitted.

The processing container (1) is formed of a conductive metal material in a substantially cylindrical shape, and a circular rotary disk (2) is horizontally arranged at the bottom thereof. This turntable (2)
Is fixed to a vertical rotation shaft (3) connected to a motor (not shown) of a variable speed type without permission, and rotates at a given speed in a fixed direction, for example, clockwise.

The rotating disk (2) has a diameter smaller than the inner diameter of the processing container (1), and is between the outer diameter surface of the rotating disk (2) and the inner diameter surface of the processing container (1). A ring-shaped gap (5) having a triangular cross-section, which serves as an introduction path for an ascending gas flow, is formed therein.

At the center of the rotating disk (2), a protruding member (6) having a substantially conical shape with its upper part cut off and having a hollow inside is mounted. The raised member (6) is fastened and fixed to the rotary shaft (3) by a tightening nut (7) screwed onto the upper end of the rotary shaft (3). The outer peripheral surface of the raised member (6) serves as a rolling portion that imparts rolling motion to the particles.

A plurality of spacers (9) are mounted on the upper surface of the turntable (2) at equidistantly circumferential positions directly below the lower surface of the raised member (6). By this spacer (9), a plurality of ejection ports (11) communicating with the hollow portion (10) of the raised member (6) between the upper surface of the turntable (2) and the lower surface of the raised member (6).
Is formed. A plurality of arc-shaped through holes (12) are formed at positions equidistantly arranged on the circumference of the rotating disk (2) and on the inner diameter side of the lower surface of the protruding member (6). On the lower surface of the turntable (2), a pair of annular protrusions (14) (15) are attached or integrally formed so as to be separated from each other on the inner diameter side and the outer diameter side. The bottom surface is set to the same height.
Reference numeral (16) is a handle (16) attached to lift the turntable (2) when the turntable (2) is removed.

A ring-shaped duct (19) whose upper surface is open and whose inner wall surface is formed into a smooth continuous curved surface is arranged below the turntable. The ring-shaped duct (19) is fixed to the bottom of the processing container (1) via an annular gap forming member (20) and a mounting member (21), and the inner wall surface on the outer diameter side thereof is a turntable. It is located just below the outer peripheral surface of (2). The inner diameter surface of the ring-shaped duct (19) is slidable with respect to the outer diameter surface of the elevating member (22: described later) disposed on the inner diameter side, and the sliding surface of both members (19) (22). Is hermetically sealed with an O-ring (25).

The ring-shaped duct (19) is provided with one or a plurality of airflow inlets (not shown) in the tangential direction thereof and in the same direction as the rotating direction of the turntable (2). . A gas flow (for example, an air flow) introduced from the airflow inlet swirls in the ring-shaped duct (19) in the same direction as that of the rotating disk (2), and the ring-shaped gap (5) and the air guide path (30). : See below). The gas flow that has flowed into the ring-shaped gap (5) becomes a swirl flow and rises in the processing container (1), activating the flow motion of particles.

The particles that have fallen into the ring-shaped duct (19) through the ring-shaped gap (5) during the flow are swirled in the duct (19) by the swirling gas flow introduced from the air flow inlet. Then, it is returned into the processing container (1) through the ring-shaped gap (5). Thus, the ring-shaped gap (5)
Since the particles that fall from the device are quickly returned to the processing container (1) without stopping in the ring-shaped duct (19), residual particles are mixed in the different particles even when the particles to be treated are replaced with different particles. GMP (Good Manufacturing Pract.
It has excellent characteristics in terms of ice).

The elevating member (22) has a hollow shape whose upper surface is a flat surface, and is formed in a donut shape around the rotating shaft (3). The elevating member (22) is driven up and down by an elevating drive source (not shown) including a motor and a cylinder.
The tongue-shaped seal member (2
3) is attached, and this seal member (23) is attached to the inner diameter portion of the rotating disk (2) and comes into contact with the outer diameter surface of the base portion (24) fitted to the rotating shaft (3). When going up and down, it makes airtight sliding contact with the outer diameter surface of the base (24). A locking member (27) having a step portion (26) bent to the outer diameter side is attached to the outer diameter surface of the elevating member (22). Between the inner diameter surface of the locking member (27) and the outer diameter surface of the elevating member (22), a bag-shaped accommodating portion (28) having an open lower portion is formed in an annular shape. The engagement portion (29) provided in the upper part of the wall surface on the inner diameter side of the ring-shaped duct (19) is accommodated in the (28). When the raising / lowering member (22) is lowered, the upper end of the engaging portion (29) comes into contact with the inner wall surface of the locking member (27) facing the engaging portion (29), whereby the lifting / lowering member (22) is further lowered. The operation is restricted (shown in FIG. 1). On the other hand, when the raising / lowering member (22) is raised, its upper surface comes into contact with both protrusions (14) and (15) provided on the lower surface of the turntable (2), whereby the raising movement of the raising / lowering member (22) is restricted. To be done.

Between the lower surface of the turntable (2) and the upper surface of the elevating member (22), the hollow portion of the rising member (6) communicates with the ring-shaped duct (19) and through the through hole (12). A ring-shaped air guide passage (30) communicating with (10) is formed. The gas flow branched from the ring-shaped duct (19) into the air guide passage (30) is provided at the skirt of the raised member (6) through the through hole (12) and the hollow portion (10) in the raised member (6). The particles ejected in the radial direction from the ejected outlet (11) blown off on the rotating disk (2) in the outer diameter direction.

The flow rate of the gas flow flowing through the air guide passage (30) is adjusted by moving the elevating member (22) up and down so that it is between the upper surface of the elevating member (22) and the lower surface of the protruding portion (14) on the outer diameter side. This is done by changing the distance of. Specifically, the lifting member (2
By lowering 2) and increasing the gap between the protrusion (14) and the upper surface of the elevating member (22), the cross-sectional area of the flow passage increases, so that the gas flow rate can be increased, and vice versa. The gas flow rate can be reduced by raising the elevating member (22) to reduce the gap. Then, the lifting member (2
By bringing the upper surface of 2) into contact with the lower surface of the protrusion (14), the gas flow rate can be almost eliminated.

In this way, by introducing the rising gas flow into the ring-shaped gap (5) and introducing the radial gas flow toward the outer radial direction on the rotating disk (2), the particles are collected in the processing container ( While turning 1), it flows up and down to form a fluid bed like a twisted rope at the bottom of the processing container (1) as a whole. By spraying a processing liquid such as a binder liquid or a coating liquid from the spray nozzle (32) into the fluidized bed, predetermined particle processing such as granulation or coating is performed. In the central part of the processing container (1), the particles roll on the outer peripheral surface of the raised member (6) with little influence of the gas flow, so that a rolling operation area where almost no flow action acts is secured.

According to the present invention, the ejection port (11) is provided between the lower surface of the raised member (6) and the upper surface of the rotating disk (2) toward the outer diameter side, and the ring-shaped gap is formed in the ejection port (11). Since the air guide passage (30) whose flow rate is adjustable independently of the gas flow introduced into (5) is communicated, the radial gas flow adjusted to the optimum flow rate can be ejected. Therefore, it is possible to realize an ideal rolling flow state regardless of the dimensions of the container and the turntable. Further, as described above, if a part of the gas flow introduced into the ring-shaped duct (19) is diverted to the air guide path (30), the gas flow in two directions can be generated by a single gas flow supply source. Therefore, the structure can be simplified.

FIG. 2 shows another embodiment of the present invention, in which a gas supply system (35) is provided in the air guide passage (30) as a separate system independent of the gas flow introduced into the ring-shaped gap (5). ) Is connected. Specifically, a ring-shaped air guide duct (37) having the same shape as the elevating member (22) and having openings (36) at a plurality of positions on the upper surface is provided below the turntable (2). Place this air duct (37),
The upper surface is brought into contact with the protrusions (14) and (15) of the turntable (2) and fixed to a stationary member (not shown). Air duct (37)
A supply pipe (not shown) provided with a flow rate control means such as a flow rate control valve is connected to the path.

With such a structure, the gas flow introduced into the air guide passage (30) can be independently adjusted to an optimum amount by controlling the flow rate control means, and like the device shown in FIG. The optimum rolling flow state can be realized in cooperation with the rising gas flow. In the device shown in FIG. 1, the lifting member (22)
When the partial flow rate of the gas flow is adjusted by moving up and down, the flow rate of the rising gas flow also changes in conjunction with this, so it is difficult to perform fine flow rate adjustment, but with the device shown in FIG. Since the gas flow rate of the gas flow and the gas flow rate of the radial direction gas can be controlled completely independently, such a problem does not occur, and the optimum rolling flow state can be easily realized.

5 (a) and 5 (b) show another embodiment of the shape of the ejection port (11). Of these, Fig. (A) shows that the lower end portion of the raised member (6) is extended in the horizontal direction to form an annular extended portion (3).
8) is formed, the spacer (9) is interposed on the inner diameter side of the through hole (12), and the ejection port (11) is formed in a ring shape. On the other hand, FIG. 6B shows a second ejection port (39) formed by obliquely forming a round hole, an elliptical hole, or the like in the extending portion (38) toward the upper outer diameter side. This configuration is effective for large-scale devices. According to this configuration, the gas flow is supplied from the second jet port (39) toward the upper outer diameter side in addition to the gas flow in the longitudinal direction, so that the flow state in the processing container (1) is further improved. It is possible to diversify.

At the bottom of the side surface of the processing container (1), a detector (40) for detecting the processing status of particles is incorporated. As shown in FIG. 3, the detector (40) includes a base body (41) having elasticity and insulating properties such as rubber, which is fitted into a side wall of the processing container (1), and has both end portions projected. And a rod-shaped pressure receiving body (42) horizontally inserted through the base body (41), and is arranged outside the processing container (1). One end of the pressure receiving body is connected to the stationary member (43) and the other end is connected to the pressure receiving body (42). ) And an elastic member (44) (spring) connected to the outer diameter side end portion of the. The pressure receiver (42) is
It is made of a material having excellent conductivity and corrosion resistance, for example, stainless steel, and the inner diameter side end portion thereof is inside the processing container (1) and slightly above the rotating disk (2) so as to project into the flow region of particles. It is located in. An ohmmeter is electrically connected between the pressure receiving body (42) and the processing container (1), and
Displacement detecting means (for example, a distance sensor) for detecting the positional displacement of the outer diameter side end of the pressure receiving body (42) is arranged outside the processing container (1) (the resistance meter and the displacement detecting means are not shown in the drawing. Omitted).

The detector (40) is a wetness detector for detecting the wettability of the particle surface, and a detector for detecting troubles such as the generation of aggregates and the adhesion of particles on the rotating disk (2). Function as. The operation of the detector (40) in each case will be described below.

Since the wet particles are flowing in the processing container (1), a certain amount of current can flow between the processing container (1) made of a conductive material and the pressure receiving body (42). . In this case, the wettability A of the particle surface and the resistance value R between the processing container (1) and the pressure receiving body have a hyperbolic relationship as shown in FIG. 4, and the surface water content is small. The resistance value also changes significantly depending on the difference. Therefore, the relative wettability of the particle surface can be accurately specified from the resistance value indicated by the resistance meter. If there is an excess or deficiency in the detected wetness, the wetness of the particles can be adjusted manually by the operator by adjusting the flow rate of the rising gas flow or radial gas flow, and the amount of liquid sprayed from the spray nozzle (32). To prevent problems such as powder scattering, agglomeration, and particle adhesion to the vessel wall. Furthermore, if the detection data of the resistance meter is fed back to the control device, and the control device performs sequence control of the radial gas flow, the rising gas flow, or the machining liquid supply amount so that the wetness becomes a constant value, the operator's It is possible to automatically maintain the wettability of the product at an optimum value that does not cause the above troubles without relying on experience and intuition.

When aggregated particles are generated in the processing container (1) or a large amount of particles are attached to the rotating disk (2), the pressure receiving body (42).
Aggregates and adhered particles collide with. As shown in FIG. 3, the pressure receiving body (42) tilts on a horizontal plane according to the impact force at the time of collision, and elastically returns to the initial position by the elastic force of the spring (44) after passing through aggregates. When the pressure receiving body (42) tilts, a position displacement occurs at the outer diameter side end portion, so this displacement amount is measured by the displacement detecting means, and if the measured value is larger than the set value, it is detected as aggregated particles are detected. Give a signal to warn the operator. This allows the operator to recognize the occurrence of aggregated particles without putting hands in the device or sampling, and it is possible to quickly deal with trouble without imposing an excessive burden on the operator. Become.

In addition, a similar effect can be obtained by attaching a strain gauge to the pressure receiving body (42) and measuring the amount of deflection of the pressure receiving body (42) due to the collision of aggregates with this strain gauge. .

As described above, according to the present invention, a protruding portion is provided on the upper surface of the center of the rotating disk to form a rolling portion, and between the lower surface of the protruding portion and the upper surface of the rotating disk. An outlet is provided toward the outer diameter side, and an air guide passage whose flow rate can be adjusted independently of the gas flow introduced into the ring-shaped gap is connected to this outlet, so that the flow rate is adjusted to the optimum value. A radial gas flow can be ejected, and an ideal rolling flow state can be easily realized regardless of the dimensions of the processing container or the turntable. Therefore, it is possible to simplify the work of determining the dimensions of the processing container and the turntable, and it is possible to easily deal with scale-up and scale-down of the apparatus. Further, since the outer peripheral surface of the raised portion serves as a rolling operation area in which almost no flow action is exerted, optimum circulation flow of the particle group can be realized.

By splitting a part of the gas flow introduced into the ring-shaped gap in the air guide passage, it is possible to obtain two kinds of gas flows, an ascending gas flow and a radial gas flow, with a single gas flow supply source. Can
The structure can be simplified.

If a gas supply system of another system independent of the gas flow introduced into the ring-shaped gap is connected to the air guide passage, the flow rates of the rising gas flow and the radial gas flow can be adjusted completely independently of each other. Therefore, the optimum flow rolling state can be easily realized. In this case, the flow rate of the ascending gas flow is not affected by the adjustment of the flow rate of the radial gas flow, so that finer flow rate adjustment can be performed.

Immediately below the ring-shaped gap, a ring-shaped duct having an opening facing the ring-shaped gap is provided, and the ring-shaped duct is directed tangentially and in the same direction as the rotation direction of the rotary disk. By providing an airflow inlet for guiding air, it is possible to activate the flow motion of particles as compared with the case where only a vertical gas flow is acted, and a more active flow due to a synergistic effect with the radial gas flow. It becomes possible to realize exercise. In addition, cross contamination can be surely prevented, which is excellent in terms of GMP.
