[Industrial applications]

 The present invention relates to a water-cooled rotary valve for supplying or discharging raw materials used in a steaming device for continuously steaming brewing raw materials.

[0002]

[The purpose of the device]

 Since the raw material for brewing is steamed by steam at high temperature and high pressure in a steaming can, a rotary valve with high airtightness under high temperature and high pressure is used for supplying and discharging the raw material. However, since the rotating rotor is heated by high-temperature steam, the wall surface of the compartment that contains the raw material reaches almost the steam temperature, and part of the carbohydrate in the raw material is heated and transformed into an adhesive component, and the wall surface inside the rotor. There is a problem in that it is heated for a long time while adhering to the surface, burns, and gradually thickens the deposited layer, making it impossible to supply and discharge the raw material.

In view of the above, the present invention solves the above-mentioned disadvantages of the conventional rotary valve, makes the inside of the blades forming the rotor hollow to provide a flow passage for the refrigerant, and has a plurality of stages in the flow passage. Baffle plate is projected, and the coolant is sent from the flow path on the coolant supply side provided in the rotating shaft to cool the wall surface in the compartment very efficiently, and the temperature difference causes dew condensation on the wall surface to cause sticky substances. It is an object of the present invention to provide a water-cooled rotary valve that prevents generation, scorching due to adhesion, and progress of deposition.

【Example】

 Hereinafter, a specific configuration of the water-cooled rotary valve of the present invention will be described in detail with reference to the illustrated embodiment. 1 is a longitudinal sectional view showing an embodiment of the rotary valve of the present invention, and FIG. 2 is a sectional view taken along the line AA of FIG.

The water-cooled rotary valve of the present invention is used in a continuous steaming device in which a rotor body 3 in which a plurality of blades 2 are radially connected to the outer circumference of a rotary shaft 1 is rotatably fitted in a casing 4. In the rotary valve for supplying or discharging the raw material for brewing, the rotary shaft 1 is hollow to provide the flow passage 5 for the refrigerant, and the inside of each blade 2 of the rotor main body 3 is hollow, and the flow passage 6 for the refrigerant is provided. Is provided to communicate the flow path 5 in the rotary shaft 1 and the flow path 6 in each blade 2 with the refrigerant, and cool the rotary shaft 1 and the blades 2 so that the brewing raw material becomes the rotary shaft. 1 and the blade 2 are prevented from adhering to the surface.

First, in the illustrated embodiment, the rotary shaft 1 is composed of a drive-side rotary shaft 8 and a non-drive-side rotary shaft 9 that are rotationally driven by an appropriate drive device 7. The inside of the non-driving side rotating shaft 9 is hollow and the inside of the non-driving side rotating shaft 9 is hollow to form the discharging side channel 5B of the refrigerant. A partition wall 10 is formed between 5B as shown in FIG. The flow path 5A of the drive side rotary shaft 8 is connected to the refrigerant supply pipe 12 via the rotary joint 11.

Next, the rotor body 3 has a structure in which a plurality of blades 2, 2, ... A coolant passage 6 is formed here, and a plurality of stages of baffle plates 22 are provided in the passage 6 in a protruding manner.

As shown in FIG. 1, the baffle plate 22 first protrudes from the outer peripheral portion of the rotary shaft 1 in the passage 6, and then the ceiling of the passage 6 is separated by a predetermined distance. When the projections are alternately projected from above and below so that they project downward from each other, a turbulent flow occurs in the flow of the refrigerant passing through the communication passage 6, and an efficient cooling effect can be obtained. .

On the other hand, a coolant inlet hole 13 is formed in the drive side rotary shaft 8 in order to connect the coolant supply side flow channel 5 A provided on the rotary shaft 1 and the through flow channel 6 provided at each blade 2. At the same time, in order to connect the flow passage 6 and the coolant discharge side flow passage 5B provided on the rotary shaft 1, a coolant outlet hole 14 is formed in the non-drive side rotary shaft 9. Needless to say, a plurality of refrigerant inlet holes 13 and outlet holes 14 are formed toward the center of the hollow portion of each blade 2 so as to correspond to the number of blades 2.

As described above, in the water-cooled rotary valve of the present invention, the rotor body 3 described above is rotatably fitted in the casing 4, and the tips of the drive-side rotary shaft 8 and the non-drive-side rotary shaft 9 are casing. 4 has a structure in which it projects outward from the end plate 15 of the casing 4, and a plurality of compartments 16 are formed inside the casing 4 by the inner peripheral surface of the casing 4 and the wall surface of each blade 2. Is.

In addition, in the figure, 17 is an inlet of the brewing raw material formed in the upper part of the casing 4, 18 is an outlet of the brewing raw material, 19 is a bearing of the rotating shaft 1, 20 is an end of the non-driving side rotating shaft 9. The drainage box is watertightly fitted to the drainage box, and 21 is a drainage pipe connected to the drainage box 20.

Next, the operation of the water-cooled rotary valve of the present invention will be described when it is used on the discharge side of a continuous steaming device (not shown). It enters into the chamber 16, moves downward as the blade 2 rotates, and is discharged from the outlet 18. At that time, as described above, the inside of the compartment 16 is gradually heated by the high heat of the cooked raw material and the high temperature steam in the steaming can, and the sticky substance adheres to the surface of the blade 2 to be generated.

However, in the present invention, when a coolant such as water is sent from the coolant supply pipe 12, the coolant passes through the flow path 5 A in the drive side rotary shaft 8, passes through the inlet hole 13, and then in each blade 2. Dispersed and flown into the flow passage 6, and while meandering through the flow passage 6 by the baffle plate 22, it is discharged to the flow passage 5B in the non-driving side rotary shaft 9 through the outlet hole 14 and passes through the flow passage 5B. And is discharged to the outside, the wall surface in each compartment 16 is cooled with high heat transfer efficiency.

Then, since the dew condensation occurs on the wall surface in each compartment 16 due to the temperature difference and becomes a wet state, a sticky substance is not generated in the raw material, and the raw material does not adhere to and deposit on the wall surface, and is extremely smooth. The material is discharged from the raw material outlet 18. In particular, according to the present invention, a coolant supply side flow passage 5A and a coolant discharge side flow passage 5B are separately formed inside the rotary shaft with a partition wall provided substantially at the center of the rotary shaft 1 as a boundary. In addition, since the inside of each blade 2 of the rotor body 3 is made hollow to provide the flow passage 6 for the coolant, and the baffle plate 22 at a plurality of stages is provided in the flow passage 6 in a projecting manner, Since the turbulent flow is generated in the flow paths 5A and 5B and the communication flow path 6 and the turbulent flow does not stay in one place, it is possible to completely and completely prevent the production of the adhesive substance.

[Effect of device]

 As described above, in the case of the water-cooled rotary valve of the present invention, the rotating shaft and the blades forming the rotor body are efficiently cooled by the refrigerant, and dew condensation occurs on the surface, so that the raw material adheres to and forms on the wall surface of each compartment of the rotor body. It is possible to effectively prevent this. Therefore, according to the present invention, it is possible to provide a rotary valve which is capable of continuous supply and discharge of raw materials, has no possibility of intermittent work, and has extremely high reliability.
