Abstract

(57) [Abstract] [Purpose] When a powder or granular material is distributed from a storage tank to two containers, a predetermined amount of powder or granular material can be discharged to them simultaneously or separately, and the discharge route The thing which a granular material does not remain is provided. [Composition] A butterfly valve is provided on each of the two branch passages forming the inverted Y-shaped discharge part, and when their bottom ends are in contact with the intersections of the branch passages, the inclination is greater than the repose angle of the granular material. Position as. An air cylinder is suitable for the driving means of the butterfly valve.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

  The present invention is a method in which powder particles stored in a storage tank are placed in two containers at the same time or The present invention relates to an independent two-way valve used for sequentially dropping and transferring.

[0002]

[Prior art]

  Formulation of granules in various fields such as compound feed, food manufacturing, pharmaceutical manufacturing or mining industry Or distribution is required. Traditionally, some of the powder and granules were transferred from the storage tank to multiple receivers. As a device for this, separate the outlet at the bottom of the tank into two or more Id gates, screw feeders, or tables Equipment with feeders has been used.

[0003]   Both the slide gate and the table feeder have dust particles remaining on the equipment. Sui. A similar problem exists with screw feeders. Further slide gate In some cases, due to the pressure difference between the inside and the outside, powdery particles may be ejected from the gap. Many kinds In a plant that handles powders and granules, if powders or granules remain in the equipment, undesired mixing will occur. As a result, contamination may occur. You have to. This is tedious and wasteful.

[0004]

[Problems to be solved by the device]

  The object of the present invention is to solve the above problems and to store two powder particles from a storage tank. When distributing to, etc., a predetermined amount in two containers at the same time or separately as desired. It is a device that can be discharged, and there is no risk of powdery particles remaining in the discharge route. To provide things.

[0005]

[Means for Solving the Problems]

  The two-way valve for powders and granules of the present invention is housed in a storage tank (1) as shown in FIG. The granular material (8) that has been placed on both sides of the two branch paths (4A, 4B) of the inverted Y-shaped discharge part (3). A two-way valve for discharging from one side at the same time or from one side, As you can see, butterfly valves (5A, 5B) are installed on each branch and When closing the butterfly valve, its lower end (51A, 51B) has an intersection (41) of the branch path. Positioned so that it is in close contact and its inclination (θ) is greater than the repose angle of the granular material. It is characterized by having done.

[0006]   The typical mode of this two-way valve is, as shown in FIGS. 3 to 6, opening and closing of a butterfly valve. Equipped with air cylinders (6A, 6B) that perform To control the air supply to the air cylinder at each time Limit switches (7A, 7B) are provided.

[0007]

[Action]

  As shown in FIG. 5, the butterfly valve has one (5A) closed and the other (5B) closed. ) Is in a fully opened state, the powder particles in the tank (1) flow into one branch path (4A). It does not enter and flows to the other branch path (4B). At this time, the butterflies on the closed side The lower end (51A) of the valve (5A) is near the intersection (41) of the branch path, so the flow path is It is formed smoothly. In addition, the butterfly valve (5A) tilt (θ), that is, water The inclination with respect to the plane is larger than the angle of repose of the granular material, so the granular material accumulates here. There is nothing to do.

[0008]   If one of the butterfly valves (5A) is opened, the powder and granules go to one of the branch passages (4A). Also enters, and the same amount as the other branch (4B) flows (if the size of the branch is different on the left and right) Of course, it is possible to make it, and in that case, the amount of powder and granules according to its size is Each flows).

[0009]   If the other butterfly valve (5B) is closed from this state, the state will be reversed from the initial state. Needless to say.

[0010]   Driving the butterfly valves (5A, 5B) by the air cylinders (6A, 6B) Especially when the valve is closed, the lower ends (51A, 51B) of the valve contact the intersection of the branch path. , When the upper end (52A, 52B) contacts the sheet (42A, 42B), it is appropriate It is suitable for pressing under pressure to complete the seal. Limit switch (7 A, 7B) are installed at appropriate positions to ensure proper operation of the air cylinder. I can do it.

[0011]

[Effect of device]

  By using the two-way valve for powders and granules of the present invention, two containers for powders and granules from a storage tank can be used. If desired, discharge to both simultaneously, only one, or in sequence, as desired. Then, the discharge can be performed independently. With this device, powder particles were ejected Of course, there is no concern about the occurrence of dust, and the granular material remains in the flow path and impairs the quantitative performance. And does not cause pollution.

[0012]   Since the structure of the device is simple and ready-made products can be collected and manufactured, the cost is low. Maintenance is also easy.
