Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an upper sealing device for a pot for manufacturing a product by mixing and stirring an object (including a mixture) such as a powder raw material (including “stirring only” in this specification), and a pot apparatus including the same. Specifically, the present invention relates to an upper seal device that seals between a rotating hook and a fixed side, and a hook device including the upper seal device.
[0002]
[Prior art]
Conventionally, a pot device has been used to obtain a target object by mixing and stirring a plurality of objects (including “raw material”, “semi-finished product”, and “product” in this specification). For example, as an object manufactured by mixing and stirring in such a kettle device, there are curry and stew roux manufactured by mixing and stirring (kneading) powder such as flour and oil (butter). Such an object is manufactured so that a uniform object can be obtained by mixing and stirring a plurality of raw materials in a kettle (including “kneading” in this specification).
[0003]
On the other hand, when manufacturing this kind of target object, it may mix and stir while heating, or may mix and stir while cooling. For example, the curry or stew roux is produced while mixing and stirring powder and oil such as wheat flour, so that a homogeneous object cannot be obtained unless the pot body is heated and mixed at a predetermined temperature. .
[0004]
As conventional techniques of this kind of mixing and stirring pot, there are a device described in Japanese Utility Model Registration No. 2533936 and an invention described in Japanese Patent Application Laid-Open No. 11-197481.
[0005]
[Problems to be solved by the invention]
However, the above-described prior art has a structure in which the hook body and the upper cover are fixed and the stirring tool rotates.
[0006]
By the way, this kind of target is mixed and agitated, and the main body is rotated, or the main body is fixed and the upper cover is rotated while the stirrer is rotated. There is. These configurations are selected according to the nature and type of the object, and the kettle is configured to be rotatable or the upper cover provided with the stirring tool is configured to be rotatable. It is configured to be separable.
[0007]
However, in such a hook device in which the hook body and the upper cover are relatively rotatable and separable, a clearance must be provided between the hook body and the upper cover to prevent friction during rotation. However, if a powder raw material or the like is introduced while the gap is provided at the time of stopping, the raw material may be scattered from the gap. Therefore, between the hook body and the upper cover, a structure is provided in which the gap between the hook body and the upper cover is sealed to prevent scattering of the raw materials and the hook body and the upper cover can be rotated relatively. There is a need for a sealing device that does not meet these requirements.
[0008]
Note that it is practically difficult from the standpoint of mechanical accuracy and strength to drive the shuttle main body and the upper cover relative to each other so that the gap between the two flanges is hermetically closed without providing a seal member.
[0009]
In addition, even in a hook device in which the hook body and the upper cover can be separated, there are cases where it is desired to change between a state having a predetermined gap between them and a sealed state during operation and stop, There is no sealing device that satisfies these requirements.
[0010]
[Means for Solving the Problems]
Therefore, in order to solve the above-mentioned problem, the present invention relates to a hook body having a hook body having an upper flange in an opening, and an upper cover located at an upper portion of the hook body and separable from the hook body. An upper seal device for sealing between the hook body and the upper cover, wherein a seal flange is provided at a predetermined position of the upper cover so as to face the upper flange, and between the seal flange and the upper flange, A seal member that can be deformed into a state having a predetermined gap between both flanges and a state in which the flanges are sealed is provided. Thus, a seal member is provided between the relatively separable hook main body and the upper cover, and this seal member seals between the flange having a predetermined gap between the seal flange and the upper flange. Therefore, it is possible to configure a sealing device that can be deformed into a state having a gap and a sealed state depending on when the hook body is used or stopped.
[0011]
Further, in a hook having a hook body having an upper flange in the opening and an upper cover positioned at an upper portion of the hook body and rotatable relative to the hook body, a seal is provided between the hook body and the upper cover. An upper seal device for providing a seal flange opposite to the upper flange at a predetermined position of the upper cover, and the shuttle main body and the upper cover rotate relatively between the seal flange and the upper flange. In a state where the flange main body and the upper cover are in a stopped state, a seal member is provided for sealing between the flanges. In this manner, a seal member is provided between the relatively rotatable hook body and the upper cover, and when the hook body and the upper cover are relatively rotated, a predetermined amount is provided between the seal member and the upper flange. When the hook main body and the upper cover are stopped, the seal member seals the gap between both flanges. If the seal member seals between both flanges, the seal member increases resistance and wears the seal member. Thus, it is possible to configure a sealing device that can stably seal between the two when stopped.
[0012]
Further, if the upper cover is provided with an annular side cover member that enters a predetermined amount from the upper end of the hook main body with a predetermined gap between the upper cover and the inner wall of the upper end of the hook main body, the side cover is provided. Since the member has a labyrinth shape that enters a predetermined amount from the upper end of the hook body, the side cover member can prevent the object or the like from directly hitting the inner peripheral surface side of the seal member.
[0013]
Further, if the seal flange side is fixed and a seal member is provided on the surface facing the upper flange of the seal flange, the seal member can be provided on the fixed side, thereby constituting a seal device that is easy to maintain. it can.
[0014]
Further, the seal member is constituted by a pressurizing seal member made of a flexible member having a hollow portion, the pressurizing seal member is provided on the seal flange and / or the upper flange, and the seal flange and / or the upper flange is provided. If a gas supply device for supplying gas to the hollow portion of the pressurizing seal member is provided to seal between the flanges with the pressurizing seal member, the hollow portion of the pressurizing seal member, which is a flexible member, is provided. By supplying gas, it is possible to easily seal between the hook body and the upper cover.
[0015]
In addition, by forming the inner diameter side of the pressurizing seal member so as to be expandable and contracting, the inner diameter side of the pressurizing seal member can be deformed to ensure a large deformation amount. As this one side bellows type, a form having a pleat that can be greatly deformed is adopted.
[0016]
Further, if the one-side bellows type of the pressure-type seal member is formed by providing a seal lip having an inclined surface inclined downward from the outer diameter side toward the inner diameter side on the inner diameter-side surface of the pressure-type seal member. Since the inner diameter side of the pressure-type seal member that is deformed by gas becomes a smooth inclined surface, adhesion of powder and the like can be suppressed.
[0017]
Further, if the pressure seal member is disposed so that the cleaning water for cleaning the inside of the hook body flows into the inside of the hook body with the seal lip of the pressure type seal member being in contact with the upper flange of the pot body, Washing water washed in a state where the space between the hook body and the side cover member is sealed with the pressure seal member can flow down into the hook body along the seal lip.
[0018]
Furthermore, if the pressure seal member is made of silicone rubber, a seal member having high heat resistance, cold resistance, water resistance, etc. can be constructed. Can exhibit a stable sealing function.
[0019]
On the other hand, according to the shuttle device provided with such a top seal device of the shuttle, effective sealing can be performed in the shuttle that manufactures various objects by heating or cooling. In particular, an effective sealing effect can be exhibited in a kettle that is mixed and stirred while heating the kettle in order to produce an object having viscosity (for example, curry or stew roux).
