Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an adsorption-type oil-water separation apparatus in which an adsorption tank is installed in a divided casing. In particular, it efficiently replaces the adsorbent such as activated carbon in the adsorption tank.

[0002]

In the conventional adsorption-type oil / water separation apparatus, the adsorbent must be replaced because the adsorbent deteriorates as the adsorbent approaches a saturated state. In such a case, the suction tube is often covered with a casing, and since the adsorbent is generally pulled out upward for replacement, it is necessary to provide a drawer space above. In addition, there is a disadvantage that the upper plate of the adsorption cylinder must be removed and opened when the adsorbent is replaced. The present invention has been made in view of the drawbacks of the related art, and has as its object to provide a structure that allows easy replacement of the adsorbent and does not require a special drawer space in the apparatus.

[0003]

That is, the present invention comprises a suction cylinder disposed in a casing, a mount for vertically supporting the suction cylinder at one end, and a suction cylinder provided at the other end of the suction cylinder. Normally, it has a leg for horizontally supporting, and a suction type provided with a stopper for locking the rotation of the suction cylinder in front of the rotation direction of the center of gravity of the suction cylinder in front of the gantry in the rotation direction. This object is achieved by an oil-water separator. Claim 2
The invention of the above is an adsorption type oil / water separator provided with a return prevention stopper between the back side of the adsorption cylinder and the casing wall in consideration of the case where the center of gravity of the adsorption cylinder is later.

[0004]

In the improved structure of the suction device according to the present invention, since the lower end of the suction tube located on the door side is supported via the gantry, the suction tube rotates in the vertical direction with that portion as a fulcrum. Since the stopper is arranged so that the vertical line of the center of gravity of the suction tube is located closer to the fulcrum when rotated, the suction tube is locked in an inclined state. Therefore, the worker can exchange the adsorbent by extracting the adsorbent to the door side without maintaining the inclination of the adsorption cylinder. According to the second aspect of the present invention, the position of the center of gravity of the adsorption cylinder after the adsorbent is removed is adjusted at a predetermined angle via a stopper to prevent the adsorption cylinder from falling backward when the adsorption cylinder is moved to the rear. It can be maintained in an inclined state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the illustrated embodiments. 1 and 2 are longitudinal sectional views of an apparatus according to the present invention. In a room covered with a casing 1, an adsorption tank 2 and a separation tank 3 are installed from a door side (left side in the figure). An inverted L-shaped base 4 is located below the suction tube 2.
At the door-side end of the base 4
It is supported through. The gantry 5 and the pedestal 4 support the suction tube 2 horizontally in a normal state. A handle 6 for tilting the suction tube 2 forward is mounted on a side surface of the suction tube 2. In this embodiment, the stand 4 is provided with a stopper 7 provided continuously. The locking relationship between the stopper 7 and the casing base is configured so as to be located below the center of gravity G of the suction tube 2 and forward of the fulcrum of the support.

FIGS. 3 and 4 show a second embodiment of the present invention. On an inverted L-shaped table 4, an adsorption cylinder 2 and a separation tank 3 are placed on the door side. I have. The base 4 is supported via a base 5, and a stopper 7 is provided in front of the base 5 on the door side to maintain the base 4 at a predetermined angle.
Are joined. As with the first embodiment, the position of the gantry 5 supporting the table 4 is such that the position of the fulcrum is located at the rear of the casing with respect to the vertical line of the position of the center of gravity of the entirety of the adsorption cylinder 2 and the separation tank 3 mounted on the table 4. Designed to be located. In this embodiment, one end of a rod-shaped stopper 8 is pivotally attached to the back of the separation tank 3 in consideration of the fact that the position of the center of gravity of the entirety moves backward when the adsorbent in the adsorption cylinder 2 is removed. The other end of the stopper 8 is configured to be able to be locked on the inner wall surface inside the casing. As a locking method, as shown in FIG. 2, the other end of the stopper 8 is bent into an L-shape, and the bent portion is fitted into a tubular hook 9 in a casing.

FIG. 5 is a partially enlarged view specifically showing the mounting positions of the base 4 and the gantry 5 and the structure of the stopper 7 provided on the gantry 4. In FIG. The table 4 has a horizontal member 10 on the door side.
It consists of what was connected continuously. FIG. 5 (2) shows an example in which the L-shaped member 11 is joined to the front end of the table 4 on the door side.
A rectangular parallelepiped block 12 is joined to a lower portion of the rear end of the suction tube 2 so that the suction tube 2 can be kept horizontal in a normal state. 5 (3) is the same as that of the embodiment shown in FIG. 2 except that the support of the suction tube 2 by the gantry 5 is formed on the gantry 5 so that the suction tube 2 can be attached and detached.
4 and the shaft 16 is placed in the groove 14.
In this embodiment, the horizontal groove portion is grooved toward the rear of the gantry 5 so that the fulcrum position is located behind the center of gravity of the entire suction tube 2 when the suction tube 2 is inclined.

In the improved structure of the apparatus according to the present invention having the structure described above, since the suction tube 2 pivotally supported via the table 4 can swing vertically, the handle is held when exchanging the adsorbent. The suction tube 2 is manually pulled out to the front.
Then, the vertical position of the center of gravity of the suction tube 2 is located on the door side (front side) of the fulcrum of the gantry 5.
Is irreversible. When the suction tube 2 is further inclined, the stopper 7 provided at the tip of the table 4 is locked to the floor of the gantry 5, so that the swinging position is restricted.

Next, in the embodiment shown in FIG. 3, when the adsorbent is removed while the adsorption cylinder 2 is inclined, the center of gravity of the entire adsorption cylinder 2 moves forward. Then, in some cases, the position of the center of gravity is located behind the fulcrum, so that the adsorption cylinder 2 tries to move backward, which hinders the operation of replacing the adsorbent. For this reason, the suction tube 2 is prevented from falling backward by previously engaging the hook portion of the casing 1 via the rod-shaped stopper.

In the case of (3) of the embodiment shown in FIG. 5, the table 4 on which the suction tube 2 is mounted is fitted into the L-shaped groove 14 of the frame 5 via the shaft 16. If the suction tube 2 is lifted up together with the shaft 16 along the vertical groove 14 along the vertical groove, the suction tube 2 can be removed, and when the suction tube 2 is inclined for replacement of the adsorbent, first, After moving the table toward the front along the horizontal groove of the gantry 5, the suction tube 2 is rotated in the vertical direction about the end of the groove 14. Then, since the center of gravity G of the inclined suction tube 2 is located considerably behind the fulcrum, the suction tube 2 is replaced when the adsorbent is replaced.
Is extremely unlikely to fall backward, and the operator can safely perform the operation of replacing the adsorbent.

[0011]

As described above, the improved structure of the apparatus according to the present invention is such that the casing itself can be removed even when the suction filter is taken out when replacing the adsorbent in the suction cylinder because the suction cylinder can swing. However, it does not become a hindrance, the drawing-out space of the filter can be simplified, and the casing can be made compact as compared with the conventional one in which the adsorption tube is fixed.
