Description

  The present invention relates to a mixed fluid separator that separates and discharges only one fluid having a large specific gravity from mixed fluids having different specific gravity, and more specifically, for example, automatically water having a large specific gravity mixed in an oil storage tank or the like. It is related with the separator which can be isolate | separated and discharged | emitted out of a system.

  As a conventional mixed fluid separator, for example, there is one disclosed in JP-A-10-28804. This is because an inlet, a reservoir, and an outlet of the mixed fluid are formed in the separator casing, and the mixed fluid that has flowed into the reservoir is separated by the difference in specific gravity between them. By adjusting the weight of the weight attached to the recess in the upper part of the float in the state where the outlet is directly opened and closed at the lower outer surface of the float and the separated large specific fluid is discharged outside the vessel. It adjusts the specific gravity of the float. Thereby, the specific gravity of the float is adjusted according to the specific gravity of the fluid to be discharged, and only the fluid having a large specific gravity can be discharged from various mixed fluids.

In the above conventional one, when adjusting the specific gravity of the float, the weight of the weight must be adjusted by disassembling the separator casing, so that the mixed fluid does not leak out of the separator. A valve must be arranged and opened and closed. For this reason, if the valve opening / closing operation is forgotten, there are problems that the mixed fluid leaks out of the separator and that the fluid cannot be discharged to be discharged.
JP-A-10-28804

  The problem to be solved is to provide a mixed fluid separator that can adjust the weight of the weight without disassembling the separator casing when adjusting the specific gravity of the float.

  The present invention forms an inlet, a reservoir, and an outlet of a mixed fluid in a separator casing, separates the mixed fluid that has flowed into the reservoir by the specific gravity difference, and provides a float that can move up and down in the reservoir. In a free arrangement, the outlet is directly opened and closed at the lower outer surface of the float, and the separated large specific fluid is discharged out of the vessel. It extends upward to the upper portion of the float and penetrates the separator casing. The specific gravity of the float is adjusted by connecting the attachment member and adjusting the weight of the weight attached to the portion of the attachment member protruding from the separator casing.

  In the mixed fluid separator according to the present invention, the weight of the weight can be adjusted without disassembling the separator casing when adjusting the specific gravity of the float, so that the mixed fluid does not leak out of the separator. Arise. Moreover, since it is not necessary to open and close the valve at the inlet of the mixed fluid, an excellent effect is obtained that the fluid cannot be discharged to be discharged.

  In the mixed fluid separator of the present invention, an attachment member extending upward and penetrating the separator casing is connected to the upper part of the float, and the weight of the weight attached to the portion of the attachment member protruding from the separator casing is adjusted. It adjusts the specific gravity. That is, since the weight of the weight attached to the portion of the attachment member protruding from the separator casing is adjusted, the weight of the weight can be adjusted without disassembling the separator casing when adjusting the specific gravity of the float.

  Examples of the present invention will be described. In FIG. 1, a separator casing is formed by a main body 1 and a lid 2, and a mixed fluid reservoir 3, and a mixed fluid inlet 4 and outlet 5 are provided in the main body 1 to constitute a mixed fluid separator. . The reservoir 3 communicates with the inflow port 4 and a vertically long float 6 is disposed in a free state in the space. The float 6 has a vertically long shape with a bottomed cylinder, and is vertically moved along a plurality of guides 8, 9, 10, 11 provided in the main body 1 so as to directly open and close the outlet 5 at the center of the lower outer surface 7. Arrange it freely. The float 6 can be manufactured as a hollow float by pressing and welding a stainless steel thin plate, or can be manufactured with a synthetic resin having a relatively low specific gravity such as polypropylene or polyethylene as shown in FIG. When the float 6 is made of a synthetic resin, a metal thin plate is attached to the lower outer surface 7 that is in contact with the outlet 5, but a sealing property and durability can be improved.

  An attachment member 14 extending upward and penetrating the lid 2 of the separator casing is connected to the upper part of the float 6. A snap ring 19 is attached to a portion of the attachment member 14 protruding from the lid 2, and the weight 15 is attached on the snap ring 19. By attaching weights 15 having different weights or changing the number of weights 15 to be attached, the weight of the weights 6 is adjusted to adjust the specific gravity of the float 6. The lid 2 is provided with an O-ring 20 for maintaining airtightness with the mounting member 14. The outlet 5 is disposed through the center of the valve seat member 12 screwed to the main body 1, and its downstream side communicates with the outlet 13. Although the valve seat member 12 is not shown so as to cover the side surface of the outlet 5 and the outer peripheral surface of the upper end at the upper end portion, a synthetic rubber seat as an elastic member is provided in a substantially ring shape and contacts the outer surface 7 of the float 6. Increase the sealing performance. Support seats 16 and 17 are provided at the lower part of the float 6 to support the float 6 when it contacts the valve seat member 12. The support seats 16 and 17 provide a space between the lower part of the float 6 and the bottom of the main body 1. A space 18 is formed in the space to be a space for collecting foreign matters such as dust. A pressure equalizing pipe 22 communicating with the reservoir 3 is connected to the upper part of the main body 1 via a valve 21, and a blow pipe 25 communicating with the reservoir 3 is connected to a lower part of the main body 1 via a valve 23.

  The state shown in FIG. 1 shows a state where the float 6 is lowered downward and the outlet 5 is closed. The mixed fluid flows in from the inflow port 4, and the fluid having a large specific gravity is separated into the lower portion and the fluid having a small specific gravity is separated and accumulated in the upper portion. When the amount of fluid having a large specific gravity increases and reaches the floated liquid level of the float 6, the float 6 floats up and is separated from the valve seat member 12 to open the outlet 5, thereby collecting the fluid having a large specific gravity. Is discharged from the outlet 13 to the outside of the vessel. When the fluid with a large specific gravity is discharged and the floating liquid level is lowered, the float 6 is also lowered at the same time, and the outlet 5 is closed while leaving a fluid with a large specific gravity at the bottom of the reservoir 3 so that the fluid is accumulated at the top. There is no leakage of fluid with small specific gravity. The apparent weight of the float 6 is adjusted by adjusting the weight of the weight 15 attached to the portion protruding from the lid 2 of the attachment member 14 in accordance with the specific gravity of the fluid to be discharged out of the mixed fluid flowing in from the inlet 4. By appropriately adjusting the specific gravity, only a fluid having a predetermined specific gravity can be discharged outside the apparatus.
