[Problems to be solved by the device]

 However, in any of the conventional devices described above, since the raw material inlet 500 is fixed to the valve, the upper surface 508 of the raw material inlet 500 and the lower surface 509 of the raw material outlet 506 are tightened when the sealing member is tightened by the pressing device. The distance has changed. Therefore, a member that absorbs the distance had to be placed somewhere in the pipe connected to the vertical rotary valve, and there was concern about the strength of the pipe line.

In view of the present situation, the inventors of the present application have earnestly studied, and as a result, when the raw material inlet and the seal plate are relatively movably engaged with each other, the upper surface 508 of the raw material inlet 500 and the lower surface of the raw material outlet 506 are in contact. The inventors have found that it is possible to press the seal member without changing the distance of 509, and completed the present invention.

That is, the invention of the present application, a valve housing having a raw material inlet in the upper portion and a raw material outlet in the lower portion, a rotor provided inside the valve housing and horizontally rotating around a vertical axis and having a raw material storage chamber, Upper and lower seal members having communication ports that are provided above and below the rotor to individually communicate the raw material inlet and exhaust ports with the rotary moving raw material storage chamber, and the seal member installed on the upper cover of the valve housing. And a pressing mechanism for pressing the rotor in the axial direction of the rotor, the raw material introduced into the raw material storage chamber from the raw material inlet is transferred to the raw material outlet by the rotation of the rotor, and is discharged to the outside by its own weight. The vertical rotary valve is characterized in that a raw material charging port and a communication port of an upper sealing member are communicated with each other in a vertically movable manner.

[Specific means for solving the problem]

 In FIG. 1, reference numeral 1 denotes a vertical rotary valve according to the present invention, and the valve 1 comprises a cylindrical valve housing 2 and a rotor 4 arranged inside thereof. The valve housing 2 is composed of a cylindrical main body 20, a disc-shaped upper cover 21 and a lower cover 22 that close the upper and lower sides of the cylindrical main body 20, and a flange projecting radially outward on the upper and lower outer circumferences of the main body 20. The parts 23 and 24 and the peripheral parts of the covers 21 and 22 are joined by bolts and nuts 27 with packings 25 and 26 interposed. As a result, a sealed internal chamber 28 is formed in the valve housing 2.

An opening 30 for inserting a tubular member 29 forming the raw material inlet 3 is provided at a part of the upper cover 21 from the peripheral portion, and the tubular member 29 is fixed to the opening 30 by welding or the like. And is kept airtight.

A rotor 4, which is a vertical rotary valve body, is provided in the inner chamber 28 of the valve housing 2. The rotor 4 includes disc-shaped upper and lower substrates 33 and 34, and a peripheral portion therebetween. It is composed of a plurality of cylindrical bodies 35 vertically arranged in a radial pattern. The upper and lower substrates 33 and 34 are provided with the same number of openings 36 and 37 as the number of the cylinders 35 communicating with the inside of each cylinder 35, respectively, and the inner space of the cylinders 35 and the openings 36 and 37 allow A raw material storage chamber 38 is formed.

The rotor 4 is connected via a cylindrical holder 39 and a key 40 to a vertical drive shaft 5 provided so as to extend vertically through the central portions of the upper and lower substrates 33 and 34. The drive shaft 5 is extended to the outside of the upper and lower covers 21 and 22 through through-holes 41 and 42 provided at the central portions of the upper and lower covers 21 and 22. In the figure, 43 and 44 are gland packings that seal between the through holes 41 and 42 and the drive shaft 5.

As will be described later, the drive shaft 5 is rotationally driven by directly connecting an upward extending portion to a motor to be described later, and the lower end portion 45 is supported by a support stay 46 attached to the lower cover 22 via a bearing 47. It is rotatably supported, and a support stay 48 attached to the upper cover 21 supports the intermediate portion 49 of the upward extending portion via a bearing 50. The rotor 4 is rotationally driven in the valve housing 2 by the drive shaft 5 described above.

As shown in FIG. 6, the cylindrical bodies 35 are arranged equidistantly from the drive shaft 5 and equidistantly in the circumferential direction. In this embodiment, six are provided.

A raw material discharge port 6 is provided in a part of the peripheral portion of the lower cover 22, and the raw material discharge port 6 is a cylindrical extension formed upright from the periphery of an opening 51 formed in the lower cover 22. Formed in part 52. The discharge port 6 is provided at a position displaced by 180 degrees with respect to the raw material charging port 3 described above and the drive shaft 5 in the embodiment. As a result, the raw material inlet 3 and the raw material outlet 6 are located on the opposite side of the drive shaft 5 from the cylinder 35 when the raw material storage chamber 38 of the cylinder 35 is located at the same position as the raw material inlet 3. The storage chamber 38 of the other cylindrical body 35 in is located at the same position as the raw material discharge port 6. Therefore, the raw material storage chamber 38 of one cylinder 35 does not communicate with both the raw material inlet 3 and the raw material outlet 6 at the same time.

The raw material inlet 3, the raw material outlet 6, and the raw material storage chamber 38 have circular cross sections, and their diameters are substantially equal. Further, the raw material input port 3 and the raw material discharge port 6 are both arranged at positions such that their axial centers coincide with the raw material storage chamber 38, and when the tubular body 35 comes to a predetermined position, the tubular body Reference numeral 35 corresponds to the raw material inlet 3 or the raw material outlet 6.

Disc-shaped seal plates 7 and 8 are arranged above and below the upper and lower substrates 33 and 34 of the rotor 4, respectively. The lower seal plate 8 is arranged on the lower cover 22. The lower substrate 34 of the rotor 4 slides on the upper surface of the lower seal plate 8 at a predetermined pressure. A part of the lower seal plate 8 is provided with a communication port at a position corresponding to the raw material discharge port 6 described above, and an insertion port 54 of the drive shaft 5 is provided at the central part. Reference numeral 55 in the figure is a stopper for fixing the lower seal plate 8 to the lower cover 22.

In the lower seal plate 8, if the rotor 4 is rotated rightward when viewed from above in FIG. 1 at the downstream side of the communication port 53 communicating with the raw material discharge port 6 in the rotor rotation direction, for example, when operating, A deaeration port 56 is provided on the front side of the. (See Figure 7)

The deaeration port 56 provided in the lower seal plate 8 is located at a position where it does not communicate with the storage chamber 38 when the raw material storage chamber 38 of a certain tubular body 35 is in communication with the raw material discharge port 6. It is provided as shown in FIG. In the above-described embodiment, the degassing port 56 is provided at a position which is displaced by 90 degrees in the circumferential direction from the raw material discharge port 6 with respect to the drive shaft 5. A degassing pipe 57 communicating with the atmosphere is provided in the lower cover 22 at a position corresponding to the degassing port 56 of the lower seal plate 8.

Therefore, paying attention to one tubular body 35 of the rotor 4, the tubular body 35 first receives the raw material through the raw material inlet 3 with the rotation of the rotor 4, and then this raw material is fed. The gas is discharged to the discharge outlet 6, and at this time, the relatively high pressure gas on the discharge system side flows into and fills the raw material storage chamber 38, but this high pressure gas continues to pass through the degassing port 56 and the degassing pipe 57. As a result, the raw material storage chamber 38 is degassed to the atmosphere.

That is, if the high-pressure gas on the discharge system roadside remains in the raw material storage chamber 38, when the cylindrical body 35 receives the raw material from the raw material inlet 3 again, the residual high-pressure gas flows into the supply system roadside. In addition, it impedes the flow of raw materials, which is not preferable. However, when the vertical rotary valve 1 is used in a system where the pressure on the discharge system side is not so high, the degassing port 56 and the degassing pipe 57 are not necessary.

On the other hand, the upper seal plate 7 is arranged on the upper substrate 33 of the rotor 4, and the upper seal plate 7 is provided with a communication port 58 communicating with the raw material charging port 3. A slightly larger hole is coaxially formed in the upper portion of the communication port 58, and the tubular member 29 is slidably inserted therein through a seal member 59 such as an O-ring. An insertion opening 60 for the drive shaft 5 is provided at the center of the upper seal plate 7.

With this configuration, it is possible to move relative to the upper seal member 7 and the upper cover 21, and even if the upper seal plate 7 is pressed downward by the pressing mechanism 9 described later, the raw material inlet 3 The distance between the upper surface 85 and the lower surface 86 of the raw material discharge port 6 does not change.

The pressing mechanism 9 includes a holder 61 vertically provided on the upper cover 21, a packing 62 accommodated in a lower portion of the holder 61, a nut 63 for pressurizing the packing 62, and a lower end of the nut 63 which vertically penetrates the nut 63. The part 65 is composed of an adjust screw 66 that abuts a part of the upper surface of the upper seal plate 7. A recess 67 that engages with the lower end portion 65 of the screw 66 is provided on the upper seal plate 7, and the upper seal plate 7 is pressed by the screw rotation of the adjusting screw 66, and the upper and lower substrates 33 and 34 of the rotor 4 are vertically moved. Adjust the seal pressure between the seal plates 7 and 8 of.

In order to equalize the sealing pressure, a plurality of pressing mechanisms 9 are preferably provided, and in the embodiment, two pressing mechanisms 9 are provided 180 degrees apart with respect to the drive shaft 5. The engaging relationship between the recess 67 and the adjusting screw 66 contributes to the rotation of the upper seal plate 7 in addition to the above pressing.

As a material for the upper and lower seal plates 7 and 8, sintered metal or ceramic is preferably used, but a soft plastic material such as Teflon can also be used. When the upper seal plate 7 is made of a soft member 7a, it is preferable to provide a backup material 7b made of a metal material on the seal plate 7 as shown in FIG. Reference numeral 7c is a stopper for preventing rotation of both 7a and 7b. 67a is a recess that engages with the lower end portion 65 of the screw 66.

The operation of the vertical rotary valve 1 is as follows. First, when the raw material is introduced through the raw material introduction port 3 and the rotor 4 rotates to expose the raw material storage chamber 38 of a, for example, directly below the introduction port 3, the raw material storage chamber 38 is stored in the raw material storage chamber 38, and the rotor 4 is stored. Further rotation, the raw material storage chamber 38 is sealed by the upper and lower sealing plates 7 and 8 at a position separated from the raw material inlet 3 and the communication port 58 of the upper sealing plate 7. The sealing pressure is adjusted by the pressing mechanism 9 described above to perform the sealing. In this case, since the upper and lower members 7 and 8 are plate-shaped and the upper and lower substrates 33 and 34 are sandwiched vertically, a sufficient surface pressure is obtained. Also, high surface tightness is maintained due to surface contact. When the rotor rotates and the raw material storage chamber 38 reaches the position of b, it communicates with the raw material discharge port 6 to discharge the raw material in the raw material storage chamber 38, and after discharging, reaches the degassing hole 56 by the rotation of the rotor and is degassed. To smoothly receive the next raw material. Repeat the above.

By the way, in the present embodiment, the following medium circulation mechanism is adopted. That is, 10 is a medium introduction port provided in a part of the peripheral wall of the valve housing main body 20, and 11 is a medium discharge port provided in a part of the lower cover 22, which are connected to the switching valves 90 and 91. The pipes 92, 93 provided are connected to the outside, and the medium is introduced into the inner chamber 28 of the valve housing 2. The medium may be selected according to the raw material or the treatment method in the next step. For example, in the case of a raw material that easily adheres to the wall surface of the raw material storage chamber 38, cold water is supplied to the inner chamber 28 to cause the cylindrical body 35 to move. Cooling. When the raw material is heated in the next step, steam or hot water is supplied as preheat into the inner chamber 28 to heat the cylindrical body 35. Further, when the pressure treatment is performed in the next step, a medium having a higher pressure than that pressure is introduced into the internal chamber 28, whereby it is possible to prevent the fine raw material from leaking from the sealed portion.

On the other hand, as the operating time of the vertical rotary valve 1 increases, the lower surface of the upper seal plate 7 and the upper surface of the lower seal plate 8 wear. However, since the upper and lower sealing plates 7 and 8 are in surface contact with the upper and lower substrates 33 and 34 of the rotor 4, respectively, such wear is uniform. Therefore, when the vertical rotary valve 1 is used, by adjusting the pressing force of the adjusting screw 66 of the pressing mechanism 9 in a timely manner, the internal chamber 28 of the valve housing 2 of the raw material storage chamber 38 of the rotor 4 is adjusted. The seal against is easily maintained.

Next, a modified embodiment of the pressing mechanism 9 for the upper seal plate 7 will be described. FIG. 9 shows an example in which a hydraulic cylinder is used as the drive source of the pressing mechanism. Instead of the adjusting screw 66 passing through the packing 62 and the nut 63, a rod 68 is brought into abutting engagement with the upper seal plate 7, and the rod 68 is moved downward by supplying pressure oil to a hydraulic cylinder 70 supported by a mount 69. Then, the seal plate 7 is pressurized. In this embodiment, in order to keep the pressure on the sealing surface 7d constant, the load current of the motor 15 which changes depending on the pressure is detected to control the operation of the hydraulic cylinder 70.

That is, the load current of the motor 15 for rotationally driving the drive shaft 5 is detected by the ammeter 71, this signal is input to the controller 72, and the controller 72 issues a command to the servo valve 73 according to the signal. , The pressure of the hydraulic cylinder 70 is controlled to adjust the pressure on the sealing surface. As a sensor for more accurate control, in the embodiment, a pressure sensor 74 is installed at the contact portion between the rod 68 and the upper seal plate 7 to detect the pressing force of the rod 68 to control the cylinder pressure. May be. It is also possible to detect the amount of leakage of a medium such as water vapor from the sealing surface and control the hydraulic cylinder 70 accordingly.

10 and 11 show another embodiment of the pressing mechanism 9. In FIG. 10, a disc spring 75 is interposed between the lower seal plate 8 and the lower cover 22, and a downward concave portion 76 is provided in a part of the seal plate 8 and a free space is provided in a part of the lower cover 22. The protrusion 77 is provided so as to regulate the movement in the plane between the seal plate 8 and the lower cover 22, and the disc spring 75 is arranged around the protrusion 77 to perform the spring guide.

FIG. 11 shows a coil spring 78 interposed between the lower end surface of the lower end portion 65 of the adjusting screw 66 and the bottom surface 67b of the recess 67a of the upper seal plate 7 as shown in FIG. The depth is made larger than in Fig. 1 to prevent the screw tip from coming off. According to the embodiments shown in FIGS. 10 and 11, the vertical vibration of the rotor 4 during the operation of the vertical rotary valve 1 can be effectively absorbed, as compared with the above embodiments.

FIG. 12 shows a specific example of use of the vertical rotary valve 1 according to the present invention. The vertical rotary valve 1 is used as a raw material charging device 13 and a product discharging device 16 in a pressurizing heat treatment apparatus. Here is an example of the usage. 12 is a steaming can, which is an apparatus for pressurizing and heating a raw material, such as soybean, using saturated steam. Reference numeral 13 denotes a raw material charging device, which uses the vertical rotary valve 1 according to the present invention, the raw material feeder 14 is exposed above the raw material charging port 3, and the raw material discharging port 6 is connected to the inlet 80 of the steaming can 12. The raw material is airtightly supplied to the steaming can 12 via the vertical rotary valve 1, and the heated steam is introduced into the internal chamber 28 by attaching the above-described pipes 92 and 93 to the steaming can 12. The vertical rotary valve 1 is preheated. Reference numeral 15 in the drawing denotes a rotor driving motor, which drives the drive shaft 5 by the chain and sprocket mechanism 81.

The raw material that has been heated under pressure in the steaming can 12 is transferred to the product discharging device 16 and discharged. As the product discharging device 16, the vertical rotary valve 1 is also used, which is connected to the discharging port 82 of the steaming can 12 and the raw material charging port 3 of the product discharging device 16 from which the processed raw material is received and the raw material discharging port is provided. Take out from 6 as a product.

As can be understood from the above, in the product discharge device 16 including the vertical rotary valve 1, the processed product is sent from the discharge port 82 of the cooking can 12 into the raw material storage chamber 38 of the rotor 4. The high temperature and high pressure gas is discharged from the raw material storage chamber 38 at the time when the product is discharged from the raw material discharge port 6. Therefore, the vertical rotary valve 1 used as the product discharge device 16 does not necessarily require the deaeration hole 56 and the deaeration pipe 57.

By the way, in the above embodiment, the raw material in the raw material storage chamber 38 of the rotor 4 dropped to the raw material discharge port 6 by its own weight. That is, the discharge of the raw material from the vertical rotary valve 1 was spontaneously performed by gravity. FIG. 13 shows a vertical cross section of a vertical rotary valve 100 according to a modified embodiment of the present invention. In the valve 100, the raw material once stored in the raw material storage chamber 38 of the rotor 4 is It is forcibly discharged to the raw material discharge port 6 by the same heating medium as in the raw material processing system on the discharge side of the vertical rotary valve 100. Since the basic structure and basic functions of the rotary valve 100 other than the heating medium introduction mechanism are the same as those of the rotary valve 1, unnecessary description will be omitted and the vertical rotary valve 1 will be omitted. The same members as those in have the same numbers.

The upper cover 21 of the valve housing 2 of the vertical rotary valve 100 is formed with a through hole 101 having an axis that matches the axis of the raw material discharge port 6. A cylindrical member 104 for forming a heating medium introduction port 103 having the same diameter as the raw material discharge port 6 is inserted into the through hole 101. The space between the cylindrical member 104 and the through hole 101 is fixed and sealed by welding or the like as described above. The upper seal plate 7 is formed with a circular communication port 109 that is concentric with the heating medium introduction port 103 and has substantially the same area. The communication port 109 communicates the heating medium introduction port 103 with the raw material storage chamber 38 in communication with the raw material discharge port 6, and thereby sends the heating medium into the raw material storage chamber 38, whereby the raw material storage chamber 38 It is arranged to forcibly discharge the raw material of the above into the discharge port 6. The engaging means between the raw material inlet 3 or the heating medium inlet 103 and the upper seal plate 7 is the same as that in the embodiment shown in FIG.

14 and 15 are a plan view and a bottom view of the vertical rotary valve 100 shown in FIG. That is, two pressing mechanisms 9 are symmetrically arranged with respect to the drive shaft 5, and the lower cover 22 is formed with a deaeration pipe 57.

FIG. 16 shows an example in which the vertical rotary valve 100 is applied to an air flow type heating device. The airflow type heating device 200 is provided in a heating pipe 209 for heating the raw material while carrying the airflow of the superheated steam and for carrying out the heat treatment, a cyclone 203 for separating the heated raw material and the heated steam, and a discharge port 206 of the cyclone 203. Used as a discharge valve 208 for hermetically discharging the raw material out of the system, a circulation blower 205 for circulating heated steam, a super heater 207 for heating superheated steam whose temperature has decreased due to contact with the raw material, and a raw material charging device. The vertical rotary valve 100 is formed. The raw material discharge port 6 of the vertical rotary valve 100 is connected to the upstream side of the heating pipe 209, and the inlet 202 of the cyclone 203 is connected to the downstream side thereof.

Further, the outlet 204 of the cyclone 203, the suction port of the circulation blower 205, the discharge port of the blower 205 and the heating medium inlet 103 of the vertical rotary valve 100 are connected via the super heater 207 to the pipes 210 and 211, respectively. , 212 to form a circulation system 201. A saturated steam supply pipe 213 is connected to the pipe 211 and supplies saturated steam to the circulation system 201.

The airflow heating device 200 is configured as described above, and the raw material supplied from the raw material feeder 14 to the vertical rotary valve 100 through the raw material feeding port 3 has the rotor 4 in FIG. After that, it is discharged from the raw material discharge port 6 by the action of the stream of superheated steam. Next, the raw material is heated in the heating pipe 209 in the air stream, separated from the heated steam in the cyclone 203, and recovered as a product from the discharge valve 208. On the other hand, the heated steam flows through the circulation system 201 by the action of the circulation blower 205.

FIG. 17 shows a partial modification of the heating medium inlet 103. That is, a baffle member 310 that concentrically reduces the area of the medium flow path is arranged in the middle of the heating medium introduction port 103. The baffle member 310 includes a cylindrical portion 312, a conical portion 311, and two support plates 313 for connecting the cylindrical portion 312 to the inner wall of the cylindrical member 104.

According to this structure, the heating medium guided to the heating medium introduction port 103 is supplied into the raw material storage chamber 38 after the flow velocity is increased by the baffle member 310. Therefore, the raw material in the chamber 38 is discharged more effectively. Moreover, since the heating medium having the increased flow velocity is supplied to the raw material storage chamber 38 along the inner wall of the cylindrical body 35 of the rotor 4, the discharge of the raw material becomes more reliable. In particular, the adhesion of the raw material to the inner wall of the tubular body 35 is reliably prevented.

FIG. 17 shows another partially modified embodiment of the heating medium introducing port 103. That is, a twisting blade member 410 for generating a swirling flow is arranged in the middle of the heating medium introducing port 103. The twisting blade member 410 includes a cylindrical portion 413 arranged concentrically with the heating medium introducing port 103, and four twisting blades 414 connecting the cylindrical portion 413 to the inner wall of the cylindrical member 104. The twisting blades 414 are arranged at equal angular intervals in the circumferential direction of the cylindrical portion 413, and are inclined by a predetermined angle. Conical portions 411 and 412 are formed on the upper and lower portions of the cylindrical portion 413.

According to this structure, the flow of the heating medium guided to the heating medium introducing port 103 is rotated by the twisting blade member 410, so that the heating medium becomes a swirling flow into the raw material storage chamber 38. Inflow. As a result, the discharge of the raw material from the raw material storage chamber 38 is further promoted.
