As will be described later, in the case of this embodiment, the outflow direction (arrow 102 direction) of the gas exiting from the foreign substance storage tank 10 to the gas outflow path 82 is the inflow direction of the gas entering the foreign substance storage tank 10 from the gas inflow path 80 (arrow). 100 directions). The blocker 16 is a light object that floats on water. Thereby, when water accumulates in the foreign substance storage tank 10, the sealing body 16 floats on the water. In the case of this embodiment, the shape of the sealing body 16 is spherical. The track body 18 guides the blocking body 16 floating in the water to a location described later. The separation preventing plate 19 is attached to one end of the track body 18. When the water is not sufficiently accumulated in the foreign matter storage tank 10, the sealing body 16 is placed on the separation preventing plate 19.

  The foreign matter storage tank 10 includes a container portion 20, a lid portion 22, a sealing material 24, a fixing nut 26, and a washer 28.

  Water and other foreign substances accumulate in the container portion 20. This foreign matter was contained in the gas that passed through the gas inflow path 80 and entered the foreign matter storage tank 10. The container part 20 has a bottom part 60 and a side wall part 62. One end of the side wall 62 surrounds the bottom 60. In the case of this embodiment, the container part 20 and the cover part 22 are united.

  The lid portion 22 is connected to the other end of the side wall portion 62. Thereby, the opening of the container part 20 formed by the other end of the side wall part 62 is closed.

  The sealing material 24 is attached to the lid portion 22. The fixing nut 26 fixes the sealing material 24 to the lid portion 22. The washer 28 is sandwiched between the sealing material 24 and the fixing nut 26.

  FIG. 4 is a plan view of the lid portion 22 according to the present embodiment. Based on FIG. 1 thru | or FIG. 4, the structure of the cover part 22 concerning this embodiment is demonstrated.

  In the case of this embodiment, the cover part 22 is comprised by the flat member. The lid portion 22 includes an inflow pipe connection portion 40, an outflow pipe connection portion 42, a first foreign matter extraction hole 44, and a second foreign matter extraction hole 46. The inflow pipe 12 is connected to the inflow pipe connection portion 40. By connecting the inflow pipe 12 to the inflow pipe connecting portion 40, the inflow pipe 12 faces the bottom 60 of the container portion 20. The outflow pipe 14 is connected to the outflow pipe connecting portion 42. Therefore, in the case of this embodiment, the outflow direction (direction of arrow 102) of the gas that flows from the foreign substance storage tank 10 to the gas outflow path 82 at the connection portion between the outflow pipe connection portion 42 and the outflow pipe 14 is This is parallel to the inflow direction (arrow 100 direction) of the gas entering the foreign substance storage tank 10 from the gas inflow path 80 at the connection location with the inflow pipe 12. The outflow pipe connecting portion 42 has a communication outlet 50. The communication outlet 50 communicates the inside of the container part 20 with the gas outflow path 82.

This pipe is also used for sucking water and other foreign substances accumulated in the bottom 60 of the container section 20.

  The track body 18 is composed of a plurality (four in the case of this embodiment) of rods 70. These bar members 70 are fixed to the edge of the communication outlet 50 so as to penetrate the sealing member 24. The sealing body 16 is surrounded by these rods 70. The interval between the rods 70 is narrower than the outer diameter of the sealing body 16. The sealing body 16 floating on the water moves along these rods 70. As a result, the sealing body 16 floating in the water is guided to the communication outlet 50 by the track body 18.

[Description of usage]
The usage method of the foreign material removal device according to the present embodiment is as follows. The foreign substance remover according to this embodiment is provided in the middle of the gas flow path. Since gas lines are well known, the detailed description thereof will not be repeated here. The gas flowing through the gas pipe enters the gas inflow path 80 in the inflow pipe 12. The gas that has passed through the gas inflow path 80 enters the container portion 20. The gas that has entered the container 20 flows out to the gas outflow path 82 of the outflow pipe 14. When the gas flows out to the gas outflow path 82, moisture and other foreign matters contained in the gas remain inside the container portion 20. Thereby, the foreign substance in the gas flowing out to the gas outflow path 82 is removed from the gas. The foreign matter staying inside the container portion 20 accumulates on the bottom portion 60.

  When water accumulates in the container part 20, the sealing body 16 floats with the water. The floating sealing body 16 is guided to the track body 18. The blocking body 16 guided to the track body 18 gradually moves toward the communication outlet 50. When sufficient water has accumulated in the container part 20, the sealing body 16 closes the communication outlet 50. At that time, the space between the communication outlet 50 and the sealing body 16 is sealed by the sealing material 24. Thereby, it is prevented that water flows out to the gas outflow passage 82.

  Foreign matter such as water inside the container portion 20 is extracted from the first foreign matter extraction hole 44 and the second foreign matter extraction hole 46. When foreign matters such as water are extracted, the sealing body 16 moves away from the communication outlet 50. Thereby, the foreign substance remover can be used again.

[Effect of the foreign substance removing device according to this embodiment]
The foreign substance remover according to this embodiment is provided in the middle of the gas flow path. Foreign matter accumulates in the foreign matter remover according to the present embodiment. Since foreign matter accumulates in the foreign matter remover, it is avoided that foreign matter accumulates over a wide section of the gas flow path. Since foreign substances are prevented from accumulating over a wide section of the gas flow path, the foreign substances can be frequently separated from the gas. Since the foreign matter accumulates in the container part 20, the small amount of foreign matter can be easily collected.

<Description of modification>
The embodiments disclosed herein are illustrative in all respects. The scope of the present invention is not limited based on the above-described embodiment, and various design changes may be made without departing from the spirit of the present invention.

  For example, the outflow direction (arrow 102 direction) of the gas exiting the foreign substance storage tank 10 to the gas outflow path 82 is parallel to the inflow direction (arrow 100 direction) of the gas entering the foreign substance storage tank 10 from the gas inflow path 80. It does not have to be. The outflow pipe 14 is connected to the foreign matter storage tank 10 such that the outflow direction of the gas exiting from the foreign matter storage tank 10 to the gas outflow passage 82 forms an acute angle with respect to the inflow direction of gas entering the foreign matter storage tank 10 from the gas inflow path 80. It only has to be. In the present specification, the acute angle is an angle of 0 radians or more and less than π / 2 radians. Also in this case, when the foreign substance remover is arranged so that the foreign substance storage tank 10 is on the bottom and the foreign substance removal tank is connected to the gas pipe, the foreign substance storage tank 10 is once entered. The gas rises before leaving. In the middle of the gas rising, foreign substances contained in the gas settle. As the foreign matter settles, the foreign matter is separated from the gas. Needless to say, the foreign substance remover need not be arranged so that the foreign substance storage tank 10 is directly below the outflow pipe 14. Even when the foreign matter removing device is disposed so that the foreign matter storage tank 10 is obliquely below the outflow pipe 14, the foreign matter can be separated by the foreign matter removing device as long as the above-described operation can occur. . In this case, it is preferable that the guide path of the blocking body 16 formed by the track body 18 is inclined with respect to the outflow direction of the gas. The blocking body 16 moves by floating on water. The track body 18 guides the blocking body 16 to the communication outlet 50 using the buoyancy of water. As a result, it may be possible to smoothly guide the blocking body 16 to the communication outlet 50 when the guide path of the blocking body 16 is inclined with respect to the gas outflow direction rather than being parallel to the gas outflow direction. is there.
