Description

  The present invention relates to a separator for a compressed air circuit that is disposed in a compressed air circuit through which compressed air flows and separates and removes foreign substances contained in the compressed air.

  A separator for separating and removing foreign substances such as oil mist and ozone contained in compressed air is known (see, for example, Patent Document 1). This separator is arranged as a part of a compressed pneumatic circuit through which compressed air flows, and removes foreign matters when the compressed air passes through the separator.

FIG. 4 is a schematic view when a conventional separator is arranged in a compressed air circuit. As shown in the drawing, the compressed air pressure circuit 51 has a pipe 52 through which compressed air flows. A separator 53 is connected to the pipe 52. The compressed air passes through the separator 53 from the pipe 52, and foreign matters are removed.

  The separator 53 and the pipe 52 are connected using a union joint 54. The operator inserts the separator 53 toward the union joint 54 attached to the pipe 52, and uses a spanner or the like to turn the nut portion to connect each other.

Japanese Patent Laying-Open No. 2015-20112

  However, since the separator has a considerable weight, a support base is required. Since there is this mount, there is not much space below the separator, and it is very difficult for an operator to turn the nut portion in this narrow space. Moreover, it is necessary to prepare the union joint used as a joint separately.

  The present invention has been made in consideration of the above prior art, and an object of the present invention is to provide a separator for a compressed air circuit that improves the working efficiency when connecting the separator to the compressed air circuit and reduces the number of parts. To do.

  In order to achieve the above object, in the present invention, a hollow cylindrical separator body which is attached to a pipe forming a compressed pneumatic circuit through which compressed air flows and forms a part of the compressed pneumatic circuit, A connection portion that extends from one end portion and is to be connected to the pipe, and the connection portion is disposed on the pipe side, and is disposed on the separator main body side with respect to the reception portion. A separator for a compressed pneumatic circuit is provided, which has a press-fitting portion that is inserted and press-fitted.

  Preferably, the connection portion extends upward from the pipe, and the separator main body has an upper lid and a lower lid that are closed at both ends and spread outward from the separator main body. The lower lid is fixed in association with a plurality of binding bolts arranged around the separator main body, and the binding bolt is fixed to a frame on which the separator main body is placed.

  Preferably, the separator main body has a proper connection position where compressed air does not leak from the connection part by press-fitting the press-fitting part into the receiving part, and the mounting surface on which the separator main body of the gantry is placed Is formed at a position equal to or lower than the lower surface of the separator body at the proper connection position.

  Preferably, the connection portion extends downward from the pipe, and the separator main body has an upper lid and a lower lid that are closed at both ends and spread outward from the separator main body. The lower lid is fixed in association with each other by a plurality of binding bolts arranged around the separator body.

  According to the present invention, since the connecting portion is constituted by the receiving portion and the press-fitting portion, the connecting operation between both is facilitated. In particular, by arranging the connecting portion upward from the pipe through which the compressed air circuit flows, the press-fitting portion formed in the separator main body is press-fitted into the receiving portion by its own weight due to the weight of the separator main body. This is an effect obtained because the separator used in the compression / pneumatic circuit is very heavy as a single unit, and realizes easy connection using this weight. And by comprising a connection part in this way, since connection members, such as a union joint, can be abbreviate | omitted, a number of parts reduces and a handleability improves.

  The weight of the separator used in the compression / pneumatic circuit can be dispersed by placing the separator main body on the gantry so that the weight of the separator is not received only by the connecting portion. By setting the height of the gantry to the same or lower than the position where the separator body is properly connected, the press-fitting part can be reliably inserted into the receiving part with the weight of the separator body. Compressed air can be prevented from leaking from the part.

1 is a schematic view of a separator for a compressed pneumatic circuit according to the present invention. It is the schematic of the connection part vicinity. FIG. 3 is a schematic view of another separator for a compressed pneumatic circuit according to the present invention. It is the schematic of the separator for the conventional compression pneumatic circuits.

  As shown in the figure, the separator 1 for a compressed air circuit according to the present invention constitutes a part of the compressed air circuit 2. That is, the compressed air also flows in the separator 1 and circulates. Specifically, there is a pipe 3 that forms a compressed pneumatic circuit 2, and a separator 1 is connected to the pipe 3 to form a part of the compressed pneumatic circuit 2. The separator 1 includes a hollow cylindrical separator body 4 and a connection portion 5 for connecting to the pipe 3. The separator body 4 is filled with a filter medium 6. The presence of the filter medium 6 separates and removes foreign matters such as oil contained in the compressed air. As the filter medium 6, for example, a material that adsorbs oil (polyethylene, polypropylene, polyethylene terephthalate, etc.) can be used.

  In the example of FIG. 1, a three-way joint (cheese) 7 is attached to a pipe 3 arranged along the floor surface, and a separator 1 is attached upward from here. In addition, although the piping 8 extended to the other side from the cheese 7 is also illustrated in the example of a figure, the edge part is closed by the valve | bulb 9. FIG. The connecting portion 5 described above is connected to the cheese 8 connected to the pipe 3. Specifically, the connecting portion 5 includes a receiving portion 10 and a press-fitting portion 11. The receiving portion 10 is disposed on the pipe 3 side, and the press-fitting portion 11 is disposed on the separator body 4 side. The press-fitting part 11 is inserted into the receiving part 10 and press-fitted.

  Both ends of the separator body 4 are closed by the upper lid 12 and the lower lid 13. The upper lid 12 and the lower lid 13 have a diameter that spreads outward from the separator body 4. Therefore, the upper lid 12 and the lower lid 13 have a protruding portion 14 that protrudes outward from the separator body 4. A through hole is formed in the protruding portion 14, and a binding bolt 15 is inserted through the through hole. A plurality of the binding bolts 15 are arranged, and the upper lid 12 and the lower lid 13 are bound to each other, and are made to act so as to be close to each other by being bound. That is, the separator main body 4 is sealed. The bundling bolt 15 is securely tightened by the nut 16. The binding bolt 15 further extends downward, and is fixed to a gantry 17 on which the separator main body 4 is placed. Specifically, since there is a nut 16 for fixing the binding bolt 15 on the lower side of the lower lid 13, the separator body 4 is placed on the mount 17 via the nut 16. A nut 18 is further provided on the lower side of the gantry 17, and this is screwed into the lower end of the binding bolt 15 to be securely fixed. By providing such a gantry 17, it is possible to prevent the weight of the separator main body 4 used in the compression / pneumatic circuit from being received only by the connecting portion 5, and by placing the separator main body 4 on the gantry 17, Weights can be distributed.

  A through hole is formed in the center of the upper lid 12 and the lower lid 13, the outlet pipe 19 is connected to the upper lid 12, and the connecting portion 5 is connected to the lower lid 13. As described above, the connection portion 5 includes the press-fit portion 11 and the receiving portion 10, and one end of the press-fit portion 11 is connected and fixed to the through hole of the lower lid 13 (press-fit and fixed in FIG. 2). . The press-fitting portion 11 has a hollow and substantially cylindrical shape, and the other end opposite to the lower lid 13 side is press-fitted into the receiving portion 10. Accordingly, one end portion of the receiving portion 10 into which the press-fit portion 11 is press-fit is larger than the diameter of the press-fit portion 11 and is set to a diameter that can accept the end. The other end of the receiving portion 10 is connected and fixed, for example, by being press-fitted into the cheese 7.

  When the press-fitting part 11 is press-fitted into the receiving part 10, the inner wall surface of the receiving part 10 and the outer surface of the press-fitting part 11 are in close contact so that the compressed air flowing does not leak. In order to reduce this leakage more reliably, O-rings 20 (two in the drawing) are arranged at the press-fit end portion of the press-fit portion 11.

  When the separator 1 is actually installed, the receiving part 10 is attached to the cheese 7 attached to the pipe 3. Then, with the press-fit portion 11 attached to the lower lid 13, the press-fit portion 11 is inserted into the receiving portion 10 from above. At this time, since the separator body 4 is for compressed air and has a considerable weight, it is press-fit as it is with its own weight. As an operator, if only the alignment between the press-fitting part 11 and the receiving part 10 is performed, the connection can be made almost automatically.

  Thus, since the connection part 5 is comprised by the receiving part 10 and the press-fit part 11, both connection work becomes easy. In particular, by arranging the connection part 5 upward from the pipe 3 through which the compressed air circuit flows, the press-fitting part 11 formed in the separator body 4 is press-fitted into the receiving part 10 by its own weight due to the weight of the separator body 4. Will be. This is an effect obtained because the separator main body 4 used in the compression / pneumatic circuit is very heavy as a single body, and realizes easy connection using this weight. And by comprising the connection part 5 in this way, since connection members, such as a union joint, can be abbreviate | omitted separately, a number of parts reduces and a handleability improves.

  Here, the position where the press-fitting portion 11 is firmly press-fitted and the compressed air is press-fitted into the receiving portion 10 to the extent that the compressed air does not leak at the connection portion 5 is defined as an appropriate connection position. At this time, the mounting surface on which the separator body 4 of the gantry 17 is placed is formed at a position equal to or lower than the lower surface of the separator body 4 (the lower surface of the lower nut 16) at the proper connection position. It is preferable. This prevents the lower surface of the separator body 4 from coming into contact with the gantry 17 during press-fitting of the press-fitting part 11 into the receiving part 10 and prevents the press-fitting from being stopped halfway. The part 11 can be inserted into the receiving part 10, and leakage of compressed air from the connection part 5 can be prevented.

  In addition, as shown in FIG. 3, you may attach the connection part 5 to the upper cover 12 side. What is necessary is just to provide the cheese 22 in the piping 21 in the upper side of the separator main body 4, and attach the connection part 5 similar to the structure mentioned above here. Even with such a configuration, a simple and quick connection operation can be realized. As shown in FIG. 3, if the connecting portions 5 are provided on both the upper and lower sides of the separator 1 for the compressed pneumatic circuit, the compressed pneumatic circuit 2 can be easily formed, and the workability is further improved.
