Description

The present invention is an oil floating on the surface of the liquid floating in a liquid, dust, it relates suspended matter recovery device you suction recovery things such as a foreign material.

  Conventionally, a floating oil recovery device that collects floating oil containing oil, dust, etc. floating on the liquid level of used processing liquid (for example, coolant liquid, cooling oil, etc.) in a processing machine or the like stored in a storage tank A suspended matter recovery apparatus) has been proposed (see Patent Document 1). This floating oil recovery apparatus includes, for example, a suction float 90 as shown in FIG. The suction float 90 has a suction member (suction body portion) 93 formed with a suction port (not shown) that opens upward, and the suction member 93 is a substantially central portion of the plate-like frame 95. And a pair of floats 91 and 92 are fixed to both ends of the frame 95. The suction float 90 floats on the processing liquid L stored in the liquid storage tank 10 by the buoyancy of the pair of floats 91 and 92, and the suction member 93 is maintained in the processing liquid L. Although not shown, the suction member 93 is provided with a position adjustment mechanism in a direction perpendicular to the frame 95, and the suction member 93 maintained in the processing liquid L by this position adjustment mechanism. The position of the suction member 93 is adjusted so that the suction port is slightly lower than the liquid level of the processing liquid L.

  The floating oil recovery apparatus includes a hose 12 and a suction pump 11 in addition to the suction float 90 described above. One end of the hose 12 is connected to the suction member 93 of the suction float 90 by the connector 94, and the other end of the hose 12 is connected to the suction pump 11. Then, by operating the suction pump 11, the floating oil D containing oil and dust floating on the liquid surface of the processing liquid L is sucked from the suction port of the suction member 93 in the suction float 90, and the floating oil D is recovered in a recovery tank (not shown) via the suction member 93, the hose 12 and the suction pump 11.

  However, the suction float 90 in the conventional floating oil recovery apparatus as described above floats on the processing liquid L due to the buoyancy of the pair of (two) floats 91 and 92 arranged in a straight line. The posture is easily affected by the weight of the hose 12 extended from the member 93. When the hose 12 extends in the arrangement direction of the floats 91 and 92, for example, as shown in FIG. 8, when the hose 12 extends toward one float 91 and passes below the float 91, the weight of the hose 12 In order to generate a buoyancy that resists this, the float 91 sinks more and the suction float 90 tilts toward one float 91 side. Thus, when the suction float 90 is inclined to one float 91 side, the floating oil D floating on the surface of the processing liquid L will be sucked only from one direction of the suction port formed in the suction member 93, There is a possibility that the floating oil D cannot be efficiently sucked from the suction port.

  Some of the suction floats 90 of the floating oil recovery apparatus have a structure including three floats in consideration of stability, but depending on the size of the tank in which the processing liquid is stored, the three floats may be provided. There may be a case where there is not enough space to float the suction floats. In such a case, the suction float having two floats saves space and can be applied to a small tank. However, the stability of the two floats when the hose 12 is connected becomes a problem as described above.

The present invention is to provide a suspended matter recovery device capable of maintaining a more stable posture in a state in which the hose is connected.

The floating substance recovery apparatus according to the present invention includes a suction main body portion formed with a suction port, a first float body and a second float body which are arranged so as to sandwich the suction main body portion and are coupled to the suction main body portion. A cover plate arranged to cover the suction port above the suction port, and the suction body portion is maintained in the liquid by the buoyancy of the first float body and the second float body. A suction float that sucks in the liquid surface part from the suction port in a state and a suction float that is connected to the suction body and extends toward the first float body, and has suction force on the suction port. and a hose for applying a volume of said first float body is much larger than the volume of the second float body, and one or more floats constituting the first float body One or a plurality of float constituting the second float body, and the suction body portion, is characterized in that all are arranged in a straight line.

  With such a configuration, the buoyancy of the first float body having a larger volume out of the first float body and the second float body arranged with the suction body portion interposed therebetween can be larger than the buoyancy of the second float body. If the hose connected to the main body is extended toward the first float body, the larger buoyancy generated in the first float body acts on the suction main body so as to resist the weight of the hose.

  Each of the first float body and the second float body may be composed of a single float. Alternatively, the second float body may be composed of one or a plurality of floats, and the first float body may be the second float. The float body has a larger number of floats than the number of floats, and the total volume of all the floats constituting the first float body is larger than the total volume of all the floats constituting the second float body. It is also possible.

According to the present invention, the hose is connected to the suction main body part so that the suction floater extends to the first float body side of the first float body and the second float body arranged with the suction main body part interposed therebetween. In this state, a more stable posture can be maintained.

  According to the floating material collecting apparatus having such a suction float, it becomes possible to collect the matter floating on the liquid surface from any direction through the suction float that maintains a more stable posture in the liquid. As a result, it is possible to efficiently recover the matter floating on the liquid surface.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The suction float 20 according to the first embodiment of the present invention is configured as shown in FIGS.

  In FIG. 1 and FIG. 2, the suction float 20 has a suction main body 23 fixed to a central portion of a linear support plate 27, and a first float 21 (first float body) at one end of the support plate 27. Is fixed by the fastener 271, and the second float 22 (second float body) is fixed to the other end of the support plate 27 by the fastener 272. The suction body portion 23 includes a suction portion 25 and a substantially L-shaped suction pipe 24 connected thereto, and the suction pipe 24 is fixed to the support plate 27 in a state of passing through the support plate 27. As shown in FIG. 2 in particular, the suction portion 25 is formed with a suction port 25a that opens upward, and the suction receiving portion 25b extends in an annular shape surrounding the suction port 25a. Further, a cover plate 28 is provided so as to cross between the first float 21 and the second float 22, and one end portion of the cover plate 28 is fixed to the upper end portion of the first float 21 by a fastener 281, and the cover The other end of the plate 28 is fixed to the upper end of the second float 22 by a fastener 282.

  The first float 21 and the second float 22 are made of resin or the like and have a hollow structure in which air is contained. The distance between the first float 21 and the suction body 23 (suction port 25a), the second float 22 and the suction body, in the first float 21 and the second float 22 arranged with the suction body 23 interposed therebetween. The distance between the portion 23 (suction port 25a) is substantially equal. The volume (hollow volume) of the first float 21 is larger than the volume (hollow volume) of the second float 22.

  The suspended | floating matter collection | recovery apparatus provided with the suction float 20 of the structure as mentioned above has the hose 12 and the suction pump 11 (for example, diaphragm pump) similarly to the conventional one (refer FIG. 8). One end of the hose 12 is connected to the suction pipe 24 by the connecting tool 26, extends to the first float 21 side, and passes below the first float 21. The other end of the hose 12 extending in this way is connected to the suction pump 11 as in the conventional case.

  As shown in FIG. 2, the suction float 20 that is put into a used processing liquid L (for example, coolant liquid, cooling oil) in a processing machine or the like stored in a liquid storage tank includes a pair of floats 21 and 22. The suction main body 23 is maintained in the processing liquid L by floating on the processing liquid L due to buoyancy. In this state, the volume (hollow volume) of the first float 21 arranged on one side of the suction main body 23 is symmetrically arranged with the first float 21 on the other side of the suction main body 23. Therefore, even if the weight of the hose 12 acts on the first float 21 side, the larger buoyancy generated in the first float 21 resists the weight of the hose 12. It acts on the suction main body 23. As a result, as shown in FIG. 2, the inclination of the suction body portion 23 due to the weight of the hose 12 is alleviated, and the suction portion 25 (suction port 25a, suction receiving portion 25b) is slightly lowered from the liquid level of the processing liquid L. In this position, it can be kept substantially horizontal.

  Thus, according to the suction float 20 according to the first embodiment of the present invention, the volume of the first float 21 on the side where the hose 12 extends is made larger than the volume of the second float 22, Since the float 21 can generate a buoyancy greater than the buoyancy of the second float 22, the hose 12 is connected to the suction body 23 (suction pipe 24) so as to extend toward the first float 21. A more stable posture can be maintained.

  In the suspended matter recovery apparatus provided with the suction floats 20 that float on the processing liquid L in the state as described above, the suction pump 11 (see FIG. 1) is operated so that sludge or the like floating on the liquid surface of the processing liquid L can be obtained. The floating oil D including dust is sucked from the suction port 25a (see FIG. 1) along the surface of the suction receiving portion 25b of the suction main body 23, and the floating oil D passes through the suction pipe 24, the hose 12 and the suction pump 11. To the recovery tank (not shown).

  According to this floating substance recovery apparatus, as described above, the posture of the suction float 20 is more stably maintained in a state where the hose 12 is connected to the suction body 23 (suction pipe 24). Since the inclination of the formed suction port 25a with respect to the liquid level of the processing liquid L is maintained in a relatively small state (substantially horizontal), the floating oil D floating on the surface of the processing liquid L from the suction port 25a It can be collected from any direction, and efficient suction and collection of the floating oil D is possible.

In addition, when a diaphragm pump is used as the suction pump 11 in the above-described suspended matter collection device, the floating oil D sucked from the suction port 25a due to vibration of the diaphragm may be discharged from the suction port 25a. Scattering of the discharged floating oil D can be prevented by the cover plate 28 fixed to the upper ends of the first float 21 and the second float 22 and disposed above the suction port 25a.

  The suction float 30 according to the second embodiment of the present invention is configured as shown in FIGS. FIG. 3 is a side view of the suction float 30, and FIG. 4 is a plan view of the suction float 30. 3 and 4, the same reference numerals are given to the same parts as those shown in FIG. 2.

  In the suction float 30 shown in FIGS. 3 and 4, the suction main body 23 having the suction pipe 24 and the suction portion 25 is fixed to a predetermined position of the support plate 37. Two floats 31a and 31b constituting the first float body 31 are arranged side by side on one side of the suction main body 23 of the support plate 37 and fixed by fasteners 371a and 371b. In addition, a single float (referred to as a second float) 32 constituting a second float body is fixed to the end portion of the support plate 37 on the other side of the suction main body portion 23 by a fastener 372. The floats 31a and 31b (first float body 31), the suction portion 25 of the suction body portion 23, and the second float 32 are arranged on the support plate 37 in a substantially straight line (see FIG. 4).

  The floats 31a and 31b and the second float 32 constituting the first float body 31 are formed of resin or the like as in the first embodiment, and the floats 31a and 31b (first float body 31) The volume (hollow volume) is the same as the volume (hollow) of the second float 32. Therefore, the total volume of the two floats 31a and 31b constituting the first float body 31 is larger than the volume of the second float 32 (all floats constituting the second float body). If the total volume of the two floats 31a and 31b constituting the first float body 31 is larger than the volume of the second float 32 (second float body), each float constituting the first float body 31 is used. 31a, 32b and the second float 32 may not all have the same volume. As in the case of the first embodiment (see FIG. 2), the hose 12 connected to the suction pipe 24 of the suction body portion 23 extends toward the first float body 31 and floats 31a and 31b. It is passing below.

  The suction float 30 also has a float 31a (first float body 31) fixed to one end of the support plate 37, as in the case of the first embodiment (see FIGS. 1 and 2). A cover plate 38 is provided so as to cross between the second float 32 (second float body). The cover plate 38 is fastened to the upper end of the float 31a by a fastener 381a, and the fastener 381b to the upper end of the float 31b. Further, the second float 32 is fixed to the upper end portion of the second float 32 by a fastener 382.

  As shown in FIG. 3, the suction float 30 having such a structure floats on the processing liquid L by the buoyancy of the three floats 31a, 31b, and 32, and the suction main body 23 is maintained in the processing liquid L. Become. In this state, the entire volume (total amount of hollow volume) of the two floats 31 a and 31 b constituting the first float body 31 disposed on one side of the suction body 23 is disposed on the other side of the suction body 23. Since the volume of the second float 32 is larger than the volume of the second float 32 (hollow volume), even if the weight of the hose 12 acts on the first float body 31 (floats 31a, 31b) side, A buoyancy greater than the buoyancy of the second float 32 generated in the floats 31 a and 31 b acts on the suction main body 23 so as to resist the weight of the hose 12. For this reason, as shown in FIG. 3, the inclination of the suction body portion 23 due to the weight of the hose 12 is alleviated, and the suction portion 25 (the suction port 25 a and the suction receiving portion 25 b) is slightly lowered from the liquid level of the processing liquid L. In this position, it can be kept substantially horizontal.

  As described above, according to the suction float 30 according to the second embodiment of the present invention, as in the case of the first embodiment (see FIGS. 1 and 2), the first side on the side where the hose 12 extends. The volume of one float body 31 (the total volume of the two floats 31a and 31b) is made larger than the total volume of the second float 32 (second float body), and the second float 32 (second float body) is formed by the first float body 31. The buoyancy larger than the buoyancy of () can be generated, so that the hose 12 is connected to the suction main body 23 (suction pipe 24) so as to extend toward the first float body 31 and has a more stable posture. Will be able to maintain.

  In this way, according to the floating substance recovery apparatus having the suction pump 11 and the hose 12 together with the suction float 30 that floats in a stable posture in the processing liquid L, the suction float is similar to the case of the first embodiment. The floating oil D floating on the surface of the treatment liquid L can be collected from the suction port 25a of the suction body part 23 (suction part 25) in the tool 30 from any direction, and the efficient manual suction collection of the floating liquid D can be performed. It becomes possible.

  In the suction float 30 described above, the first float body 31 is composed of the two floats 31a and 31b, and the second float body is composed of the single float 32. The float body (32) can also be composed of a plurality of floats. In that case, the number of these floats and the volume (large) of each float so that the total volume of all the floats constituting the first float body 31 is larger than the total volume of all the floats constituting the second float body (32). Is set. If the total volume of all the floats constituting the first float body 31 is larger than the total volume of all the floats constituting the second float body (32), the number of floats constituting the first float 31 is the second float body (32 ) May be less than the number of floats that constitute.

  Further, the two floats 31 a and 31 b constituting the first float body 31, the suction part 25 of the suction body part 23, and the second float 32 are arranged in a substantially straight line so as to be sandwiched between the support plate 37 and the cover plate 38. However, the arrangement of the plurality of floats and the suction portions 25 is maintained such that the posture of the entire suction float 30 does not hinder the recovery of the floating oil D in the processing liquid L. As long as it is possible, for example, as shown in FIG. The floats 31a and 31b (first float body 31), the suction part 25 of the suction main body part 23, and the second float 32 are separated from the suction part 25 without causing the suction float 30 itself to roll over depending on the position of each float. It suffices if they are arranged in a substantially constant direction within a range in which a posture capable of collecting floating oil is maintained, and preferably arranged in a straight line.

  The suction float 60 according to the third embodiment of the present invention is configured as shown in FIG. In FIG. 6, the same parts as those shown in FIG.

  In the suction float 60 shown in FIG. 6, as in the case of the first embodiment (see FIG. 2), the suction body 23 is fixed at the center of the support plate 27, and resin or the like is attached to one end of the support plate 27. The first float 61 (first float body) formed by the above is fixed by the fastener 271, and the second float 62 (second float body) formed of resin or the like at the other end of the support plate 27 is the fastener 272. It is fixed with. The volume (hollow volume) of the first float 61 and the volume (hollow volume) of the second float 62 are the same. With such a structure, the suction float 60 is in a state in which the first float 61 side and the second float 62 side are substantially balanced without connecting the hose 12 to the suction body 23 (suction pipe 24). is there.

  The suction portion 25 of the suction body portion 23 fixed to the center of the support plate 27 is inclined at a predetermined angle α so as to rise from the second float 62 side toward the first float 61 side. As a result, the edge of the suction port 25a (see FIG. 1) formed in the suction portion 25 is also inclined so as to rise from the second float 62 side toward the first float 61 side.

  As in the case of each of the above-described embodiments, one end of the hose 12 is connected to the suction pipe 24 of the suction body 23 by the connection tool 26 and the other end of the hose 12 is connected to the suction pump 11. By doing so, the suspended matter recovery apparatus is configured.

  When the suction float 60 having the above-described structure is introduced into the processing liquid L stored in the liquid storage tank, the suction float 60 is caused by the buoyancy of a pair of floats 61 and 62 as shown in FIG. The suction main body 23 is floated on the processing liquid L and is maintained in the processing liquid L. In this state, since the volume of the first float 61 and the volume of the second float 62 are the same, as shown in FIG. 7, buoyancy is generated to resist the weight of the hose 12 extending to the first float 61 side. Therefore, the first float 61 sinks more greatly in the processing liquid L. As a result, the suction float 60 is inclined so as to be lowered from the second float 62 side toward the first float 61 side as a whole. In this state, the suction portion 25 of the suction body portion 23 is inclined so as to rise from the second float 62 side toward the first float 61 side so as to cancel the inclination of the entire suction float 60. The inclination of the suction portion 25 (the edge of the suction port 25a) with respect to the liquid surface of the processing liquid L becomes smaller. For example, as shown in FIG. 7, the edge of the suction port 25a is substantially the same as the suction receiving portion 25b of the suction portion 25. It will stay horizontal.

  As described above, according to the suction float 60 according to the third embodiment of the present invention, the suction portion 25 (the edge of the suction port 25a) formed in the suction main body portion 23 is first from the second float 62 side. Since it inclines so that it may go up toward the float 61 side, the hose 12 connected with the suction main-body part 23 is extended to the 1st float 61 side, and the said suction float 60 is the 1st float with the weight of the said hose 12. Even if it is inclined to the 61 side, the inclination and the inclination of the suction part 25 are offset, so that the inclination of the suction part 25 (the edge of the suction port 25a) with respect to the liquid surface is made smaller, for example, suction The part 25 can be maintained substantially horizontal.

  In this way, the suspended matter recovery apparatus having the above-described suction float 60 in which the posture in which the suction portion 25 is properly arranged with respect to the liquid surface is stably maintained in the processing liquid L with the hose 12 connected thereto. According to (including the suction pump 11 and the hose 12), the floating oil floating on the surface of the processing liquid L from the suction port 25a of the suction body 23 (suction part 25), as in the case of each of the embodiments described above. D can be collected from any direction, and efficient suction and collection of the floating oil D is possible.

  In the suction float 60 described above, the volume of the first float 61 and the volume of the second float 62 are the same, but the present invention is not limited to this. The volume of the first float 61 may be different from the volume of the second float 62. In this case, the suction portion 25 (the edge of the suction port 25a) may be tilted so as to cancel out the tilt of the suction float 60 with the hose 12 connected.
