Description

[Detailed description of the device] [Industrial applications]

The present invention provides a novel structure that enables automation of damper operation in a slide discharge damper provided at the lower outlet, which is mainly found in dipping tanks for brewing raw materials such as rice and soybeans. is there.

[Prior art]

Japanese Utility Model Publication No. 53-14400 shows an example of a dipping tank for brewing. Although not limited to this example, the operation of opening and closing the slide damper of the discharge port is often a structure in which the male screw boss screwed into the screw rod advances and retreats to open and close the slide damper by rotating the handwheel. . The airtightness of the lower discharge port when closed is maintained by a ring-shaped packing interposed between the annular discharge port wall and the slide damper. In order to enhance the airtightness, in the above-mentioned conventional example, a spring is provided to press the slide damper against the packing, and a manual operation handle is provided to turn the spring ON / OFF.

[Problems to be solved by the device]

The above-mentioned conventional example has a structure in which the tank outlet is opened and closed manually, but the present invention is designed so that the outlet is completely sealed and after dipping in order to cope with the increase in size and efficiency of the device. The challenge was to develop a mechanism that can automatically discharge the.

[Means for Solving the Problems]

As a result of various studies on the above-mentioned problems, an opening / closing means (2) such as a motor drive is provided to the slide damper (1) at the bottom of the tank, and a packing (3) is provided to seal the damper when the slide damper (1) is closed. ) Is connected to the pressurization / depressurization line (4). A suitable example of driving the opening / closing means (2) is a motor or a cylinder.
The pressurization / depressurization line (4) is a line connected to the compressor so that the pressurization state and the normal pressure state can be arbitrarily set. A decompression means may be further connected to this, or lines for pressurization and decompression can be provided separately and independently.

[Action]

With such a structure, the slide damper (1) can automatically take an opening degree and a closed state which are arbitrarily set by the opening / closing means (2) driven by a motor or the like. This opening adjustment can be automatically performed by providing a limit switch or, in the case of a motor, setting a rotation time and a rotation speed. Therefore, drainage and discharge of raw materials can be automatically operated. When the slide damper (1) is closed, the packing (3) interposed between the annular outlet wall (11) and the slide damper (1) is pressurized by the pressurizing / depressurizing line (4), and slides. It comes into close contact with the damper (1) and becomes airtight. On the contrary, when the slide damper (1) is opened, the packing (3) is separated from the slide damper (1) by the depressurization of the pressurization / depressurization line (4) and can be opened and closed. These ON-OFF can be automatically performed by electric control of the pressurizing / depressurizing line (4).

【Example】

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a sectional view of the immersion tank, and FIG. 2 is an enlarged sectional view of an essential part of the tank lower discharge port. A plate-shaped slide damper (1) is openably and closably provided at the discharge port under the immersion tank (10), and the slide damper (1) is provided with a screw rod (5) horizontally provided on the discharge port side surface. ) Is attached to the male screw boss (6) screwed into (1), and the slide damper is opened and closed by moving the screw rod (5) forward and backward. A drive motor (7) is connected to the screw rod (5) as the opening / closing means (2), and the opening / closing operation is performed according to the difference in the rotation direction of the automatically controlled drive motor, the rotation time, and the rotation speed. The slide damper (1) may be provided with limit switches (8a to 8c) as shown in FIG. 3 within its movement range in order to ensure control at the time of fully closed, half opened and fully opened. The left limit switch (8a) detects full open, the middle limit switch (8b) detects half open, and the right limit switch (8c) detects full close. With such a structure, opening / closing control can be performed not only for the motor but also for the cylinder. In order to improve the airtightness automatically when the slide damper (1) is closed, or to automatically release the state, in the present invention, a pressurization / decompression line (4) is connected to the packing (3) so as to seal the damper. ing. The pressurization / depressurization line (4) is connected to the compressor shown in the drawing, and can be arbitrarily set to a pressurized state or a normal pressure state. In addition to this, it is possible to further connect to a reduced pressure state and forcibly separate the packing from the slide damper (1).

[Effect of device]

Since the present invention has the structure described in detail above, it is possible to completely seal the slide damper, and it is possible to discharge the brewing raw material after the immersion by automatic operation.
