Abstract

PROBLEM TO BE SOLVED: To provide a compact sedimentator capable of sufficiently separating foreign substances regardless of magnetic or non-magnetic from a liquid. SOLUTION: In the case that foreign substances (grinding and cutting swarf) 20 sedimentated in a bottom part of a sedimentation tank 16 are pushed in a cylindrical member 30 by a pushing head 32 moved up and down by an air cylinder 66, based on the movement resistance at the time of passing the mutually entangled and solidified foreign substances 20 through a foreign substance discharge pipe 34, the liquid component flows inversely to the sedimentation tank 14 side through a gap between the pushing head 32 and the cylindrical member 30 and only the foreign substances 20 are pushed into the cylindrical member 30 and pressurized. Consequently, the density of the foreign substances 20 is heightened and the foreign substances 20 are repeatedly pushed into the cylindrical member 30 by the pushing head 32, so that highly dense foreign substances 20 are gradually discharged outside through the foreign substance discharging pipe 34.

However, in the former apparatus using a belt conveyor, it is necessary to arrange a belt conveyor equipped with a raking blade in a sedimentation tank. Space is needed. In the latter device, in which a foreign substance is pulled out from the center of the bottom of the sedimentation tank by using a drawing tube and removed, a large amount of liquid is contained in the drawn foreign substance, so that a sufficient separation effect cannot be obtained and the liquid is recycled. When used, the yield is poor. As a device for removing chips from the coolant, a device utilizing a magnet as described in Japanese Utility Model Publication No. 63-23962 has been proposed. However, non-magnetic materials such as abrasives coming out of a grinding tool have been proposed. Foreign matter cannot be removed.

In the sedimentation / separation apparatus of the first invention, when foreign matter settled at the bottom of the sedimentation tank is pushed into the cylindrical member by the pushing head together with the liquid, the foreign matter passes through the foreign matter discharge pipe and is discharged. The liquid component is compressed on the basis of gravity at the time of being pushed up above the liquid level and movement resistance due to a bent portion of the foreign matter discharge pipe, and the liquid component flows backward from the gap between the pushing head and the cylindrical member to the settling tank side. As a result, the density of the foreign matter increases, and the foreign matter is repeatedly pushed into the tubular member by the pushing head.
The high-density foreign matter gradually passes through the foreign matter discharge pipe and is discharged to the outside. Since the foreign matter discharge pipe has reached a level higher than the liquid level of the liquid in the sedimentation tank, the liquid component is not discharged from the foreign matter discharge pipe as it is, but adheres to or is contained in high-density foreign matter. Only a small amount of liquid is discharged from the foreign matter discharge pipe together with the foreign matter.

As described above, according to the sedimentation / separation apparatus of the first invention, foreign matter in a liquid can be satisfactorily separated regardless of whether it is magnetic or non-magnetic. Further, in the present invention, the foreign matter is pushed into the cylindrical member by the pushing head to be compressed, and the foreign matter is passed through the foreign matter discharge pipe to be discharged. The apparatus can be configured to be more compact as compared with the case where the apparatus is arranged in a settling tank. Furthermore, since foreign matter is compressed, plastically deformable things such as chips, for example, become entangled with each other and solidified, and subsequent handling becomes easy.

According to a third aspect of the present invention, the air is supplied to the head body when the pushing head is raised, and the valve plate is opened against the elastic force, whereby the air is blown out from the lower end opening of the head body. Foreign matter that has entered the gap between the cylinder and the cylindrical member is returned to the sedimentation tank together with air bubbles, and the foreign matter is prevented from adhering to the outer peripheral surface of the pushing head and the inner wall surface of the cylindrical member, thereby preventing the gap from becoming narrower. . As a result, a predetermined gap is secured between the push head and the tubular member, and when the push head is inserted into the tubular member, the push head cannot be inserted due to biting of a foreign substance or a backflow of the liquid component occurs. Inconveniences such as impairment of the separation performance of the liquid and the foreign matter due to hindrance are avoided.

The foreign matter pushed into the cylindrical member is compressed based on gravity when the liquid is pushed up above the liquid surface through the foreign matter discharge pipe, and movement resistance due to a bent portion of the foreign matter discharge pipe, and the like. The liquid component is caused to flow backward from the gap between the cylindrical member and the pushing head to the sedimentation tank side, and the radius of curvature of the bent portion is set so as to obtain a predetermined movement resistance, that is, a compressed state of the foreign matter. When sufficient movement resistance is imparted only by gravity, the foreign matter discharge pipe does not necessarily need to have a bent portion, but may be merely curved upward with a large radius of curvature. The compression of foreign matter means that the liquid component is reduced and the density of the foreign matter is increased, and the foreign matter itself is elastically compressed,
This includes not only the case where the liquid component contained in the foreign matter is extruded, but also the case where the density of the foreign matter increases due to plastic deformation of the foreign matter. In addition, it is also possible to provide a movement resistance imparting portion such as a throttle portion having a smaller flow cross-sectional area than the cylindrical member, if necessary. The throttle portion may be provided only partially on a foreign matter discharge pipe. Alternatively, the entire foreign matter discharge pipe may have a smaller sectional area than the cylindrical member.

Since the foreign matter is brought into a predetermined compressed state, the foreign matter is brought into close contact with the inner wall surface of the foreign matter discharge pipe. Therefore, when the pushing head is moved to the extraction position based on the friction, the foreign matter inside the foreign matter discharge pipe is removed. Of the foreign matter is suppressed from moving back to the cylindrical member side, but a step is provided so that the flow cross-sectional area of the foreign matter discharge pipe becomes large in the middle, and the foreign matter cylinder is formed by engagement of the step with the foreign matter. You may make it prevent return movement to the shape member side.

This is a pressing position at which the height is substantially the same as the lower end. When the pushing head 32 is repeatedly moved back and forth between the extraction position and the pushing position, the foreign matter 20 settled at the bottom of the sedimentation tank 14 when the pushing head 32 is moved from the extraction position to the pushing position as shown in FIG. As shown in FIG. 7 and FIG. 7, the solidified material 70 composed of the compressed high-density foreign matter 20 is sequentially pushed into the cylindrical member 30 and compressed.
And is discharged from the discharge port 34a. A guide plate 71 is provided in the vicinity of the discharge port 34a.
Although the solidified material 70 extruded from 4a is guided so as to enter a disposal box (not shown), since the discharge port 34a protrudes above the liquid surface of the coolant liquid 16,
The solidified substance 70 put into the disposal box hardly contains the liquid component of the coolant liquid 16. The air cylinder 66 corresponds to a head driving unit.

Here, the foreign material 20 is mainly composed of spirally curled grinding chips having a large specific gravity.
When it is pushed in and gets stuck in the foreign matter discharge pipe 34,
Gravity when the coolant liquid 16 is pushed up to a level higher than the liquid level or the bent portions 34b, 3
The movement resistance occurs at 4c. Therefore, the pushing head 3
When the foreign matter 20 is pushed into the cylindrical member 30 together with the liquid component of the coolant liquid 16 in the step 2, the liquid component of the coolant liquid 16 is separated from the pushing head 32 and the cylindrical member 30 based on the movement resistance. Then, the foreign matter 20 is returned to the sedimentation tank 14 side, and the foreign matter 20 is mainly pushed into the cylindrical member 30 and compressed. Since the foreign matter 20 is curled grinding chips, when it is compressed and plastically deformed, it is entangled with each other and solidified, and the movement resistance at the bent portions 34b and 34c increases. In other words, the solidified material 70 in a predetermined compressed state is obtained, and the solidified material 70 is bent so that the solidified material 70 is discharged through the foreign matter discharge pipe 34.
The curvature radii of b and 34c are set. The dimension of the gap d between the pushing head 32 and the tubular member 30 is determined based on the movement resistance of the solidified material 70 when the pushing head 32 is inserted into the tubular member 30. The liquid component of the coolant liquid 16 is determined in consideration of the moving speed of the pushing head 32, the viscosity of the coolant liquid 16, and the like so that the liquid component flows backward to the settling tank 14 side. The foreign matter 20
It is desirable to set comprehensively in consideration of other conditions, such as that the pushing head 32 cannot be inserted due to biting of the pressing head.

FIG. 6 shows a state in which the pushing head 32 is being lowered, and the solidified material 70a is one in which the foreign matter 20 newly pushed into the tubular member 30 is being compressed. The liquid component contained is flowing backward from the gap d into the sedimentation tank 14. FIG. 7 shows a state in which the pressing head 32 is lowered to the pressing position, and the solidified material 70b is substantially solidified and is newly pushed into the foreign matter discharge pipe 34, and the solidified material 70 is reduced by that much. The inside of the foreign matter discharge pipe 34 is moved toward the discharge port 34a. The solidified matter 70 is further compressed on the basis of the movement resistance even in the process of being moved in the foreign matter discharge pipe 34.

When air is supplied into the air chamber 44 when the pushing head 32 is raised, the valve plate 60 at the lower end is compressed by the compression coil spring 64 as shown in FIG.
The air is ejected by being separated downwardly against the urging force and the water pressure, and the valve plate 60 is pressed against the solidified material 70 while entering the gap d between the pressing head 32 and the cylindrical member 30. The foreign matter 20 is returned into the sedimentation tank 14 together with the bubbles 88, and the foreign matter 20 is prevented from adhering to the outer peripheral surface of the pushing head 32 and the inner wall surface of the cylindrical member 30, and the gap d is prevented from becoming narrow. As a result, a predetermined gap d is secured between the pushing head 32 and the tubular member 30, and when the pushing head 32 is inserted into the tubular member 30, it becomes impossible to insert the pushing head 32 due to biting of the foreign matter 20 or the like. In addition, it is possible to avoid such a problem that the backflow of the liquid component of the coolant liquid 16 is hindered and the performance of separating the liquid and the foreign matter 20 is impaired. Further, when the valve plate 60 reaches the moving end and can be raised together with the pushing head 32, the jetted air enters the lower side of the valve plate 60, and the solidified material 7
