Abstract
Description
Technical Field
[0001] This application relates to the technical field of liquid discharge equipment, and more particularly, to a liquid drainage system. Background Art
[0002] During the industrial production process, it is usually necessary to transport the waste liquid generated after the production of the machine to the collection machine for collection. Moreover, in order to improve production efficiency, multiple identical liquid drainage machines and collection machines are usually set up in the workshop.
[0003] However, since the interfaces of each liquid drainage machine and collection machine are the same, during actual operation, it is easy for the operator to mix up the connectors, resulting in the chemicals in the collection machine being mixed, which is not convenient for later maintenance. Summary of the Utility Model
[0004] Based on the above deficiencies, this application provides a liquid drainage system to improve the problem of easy mixing of connectors in related technologies.
[0005] This application is implemented as follows:
[0006] An example of this application provides a liquid drainage system, including at least two groups of corresponding liquid drainage machines and collection machines, a first anti-misconnection joint assembly, and a second anti-misconnection joint assembly. Each liquid drainage machine is provided with a discharge interface flange, and each collection machine is provided with a collection interface flange. The first anti-misconnection joint assembly includes a first anti-misconnection male joint respectively connected to one of the discharge interface flanges and a first anti-misconnection female joint connected to one of the collection interface flanges. The first anti-misconnection male joint and the first anti-misconnection female joint are detachably connected through a first fitting, so that the waste liquid of one of the liquid drainage machines can flow into one of the collection machines through the first anti-misconnection joint assembly; the second anti-misconnection joint assembly includes a second anti-misconnection male joint respectively connected to the other of the discharge interface flanges and a second anti-misconnection female joint connected to the other of the collection interface flanges. The second anti-misconnection male joint and the second anti-misconnection female joint are detachably connected through a second fitting, so that the waste liquid of the other liquid drainage machine can flow into the other collection machine through the second anti-misconnection joint assembly; the first fitting and the second fitting are different.
[0007] In the above implementation process, a first anti-fool male connector and a first anti-fool female connector are respectively connected to the discharge interface flange of a set of corresponding liquid discharge machine platforms and the collection interface flange of the collection machine platform. When the first anti-fool male connector is connected to the first anti-fool female connector, the waste liquid in the liquid discharge machine platform can flow into the collection machine platform through the first anti-fool connector assembly. Similarly, a second anti-fool male connector and a second anti-fool female connector are respectively connected to the discharge interface flange of another set of corresponding liquid discharge machine platforms and the collection interface flange of the collection machine platform. When the second anti-fool male connector is connected to the second anti-fool female connector, the waste liquid in the liquid discharge machine platform can flow into the collection machine platform through the second anti-fool connector assembly. Since the first fitting in the first anti-fool connector assembly is different from the second fitting in the second anti-fool connector assembly, the first anti-fool male connector cannot be connected to the second anti-fool female connector, and the first anti-fool female connector cannot be connected to the second anti-fool male connector. Therefore, during the operation, the liquid discharge machine platform containing the first type of waste liquid will not be connected to the collection machine platform for receiving the second type of waste liquid, and misconnection will not occur.
[0008] In an alternative embodiment, a first disc is provided at one end of the first anti-fool male connector away from the discharge interface flange, and a second disc is provided at one end of the first anti-fool female connector away from the collection interface flange; the first fitting includes a first connecting member provided at the first disc and a first connection hole provided at the second disc, and the first connecting member is detachably connected to the first connection hole; a third disc is provided at one end of the second anti-fool male connector away from the discharge interface flange, and a fourth disc is provided at one end of the second anti-fool female connector away from the collection interface flange; the second fitting includes a second connecting member provided at the third disc and a second connection hole provided at the fourth disc, and the second connecting member is detachably connected to the second connection hole; the second connecting member cannot be connected to the first connection hole, and the first connecting member cannot be connected to the second connection hole.
[0009] In the above implementation process, by providing a first disc at one end of the first anti-fool male connector away from the discharge interface flange and a second disc at one end of the first anti-fool female connector away from the collection interface flange, the first connection hole at the second disc can be used to cooperate with the first connecting member at the first disc to realize the connection between the first anti-fool male connector and the first anti-fool female connector. Similarly, by providing a third disc at one end of the second anti-fool male connector away from the discharge interface flange and a fourth disc at one end of the second anti-fool female connector away from the collection interface flange, the second connection hole at the fourth disc can be used to cooperate with the second connecting member at the third disc to realize the connection between the second anti-fool male connector and the second anti-fool female connector. Moreover, since the second connecting member cannot be connected to the first connection hole and the first connecting member cannot be connected to the second connection hole, it is possible to avoid misconnection between the first anti-fool assembly and the second anti-fool assembly, for example, to prevent the first anti-fool male connector from being connected to the second anti-fool female connector and the first anti-fool female connector from being connected to the second anti-fool male connector.
[0010] In an alternative embodiment, the first connecting member and the second connecting member are the same, and the first connecting hole and the second connecting hole are the same; a plurality of first connecting holes are evenly spaced in the circumferential direction of the second disk, and there is a first interval angle between every two adjacent first connecting holes; a plurality of second connecting holes are evenly spaced in the circumferential direction of the fourth disk, and there is a second interval angle between every two adjacent second connecting holes; the first interval angle is different from the second interval angle and is not an even multiple of the second interval angle.
[0011] In the above implementation process, the first connecting member and the second connecting member can be set to the same structure, and the first connecting hole and the second connecting hole can be set to the same structure. To avoid misconnection, a plurality of first connecting holes can be evenly spaced in the circumferential direction of the second disk, and a plurality of second connecting holes can be evenly spaced in the circumferential direction of the fourth disk. Since the first interval angle between every two adjacent first connecting holes is different from the second interval angle between every two adjacent second connecting holes and is not an even multiple of the second interval angle, the interval distance between the first connecting members corresponding to the first connecting holes is different from the interval distance between the second connecting members corresponding to the second connecting holes and is not an even multiple of the second interval angle, so that the plurality of first connecting members at the first disk cannot be simultaneously connected to the plurality of second connecting holes at the fourth disk one by one, and similarly, the plurality of second connecting members at the third disk cannot be simultaneously connected to the plurality of first connecting holes at the second disk one by one, thus avoiding misconnection.
[0012] In an alternative embodiment, the first interval angle between two adjacent first connecting holes is 60°, and the second interval angle between two adjacent second connecting holes is 90°.
[0013] In the above implementation process, if the first interval angle between two adjacent first connecting holes is 60°, the interval angle between two adjacent first connecting members at the first disk is also 60°; if the second interval angle between two adjacent second connecting holes is 90°, the interval angle between two adjacent second connecting members at the third disk is also 90°. If the first disk is to be connected to the fourth disk, the plurality of first connecting members with an interval angle of 60° at the first disk cannot be simultaneously inserted into the second connecting holes with an interval angle of 90° at the fourth disk one by one, so they cannot be connected. The second disk and the third disk cannot be connected either.
[0014] In an alternative embodiment, the first connecting member and the second connecting member are the same, and the first connecting hole and the second connecting hole are the same; a plurality of first connecting holes are unevenly spaced in the circumferential direction of the second disk, and a plurality of second connecting holes are unevenly spaced in the circumferential direction of the fourth disk, and the first interval angle between two adjacent first connecting holes is different from the second interval angle between two adjacent second connecting holes.
[0015] In the above implementation process, since the first connecting hole at the second disk and the second connecting hole at the fourth disk are arranged at non-uniform intervals along the circumferential direction, and the first spacing angle between two adjacent first connecting holes is different from the second spacing angle between two adjacent second connecting holes, even if the first connecting member and the second connecting member are the same and the first connecting hole and the second connecting hole are the same, the second disk cannot be connected to the third disk and the first disk cannot be connected to the fourth disk, thereby avoiding mixed connection.
[0016] In an optional embodiment, the first connecting member extends into the first connecting hole and fits with the first connecting hole, and the second connecting member extends into the second connecting hole and fits with the second connecting hole; the diameter of the first connecting hole is different from the diameter of the second connecting hole.
[0017] In the above implementation process, since the diameter of the first connecting hole is different from the diameter of the second connecting hole, the outer diameter of the first connecting member is different from the outer diameter of the second connecting member, so the first connecting member cannot be extended into the second connecting hole and fit with the second connecting hole, and the second connecting member cannot be extended into the first connecting hole and fit with the first connecting hole, thereby avoiding mixed connection.
[0018] In an optional embodiment, the first connecting hole and the second connecting hole are both threaded holes, and the first connecting member and the second connecting member are both studs.
[0019] In the above implementation process, the detachable connection of the corresponding anti-foolproof male connector and anti-foolproof female connector can be achieved by utilizing the cooperation of the stud and the threaded hole.
[0020] In an optional embodiment, the first anti-foolproof joint assembly and the second anti-foolproof joint assembly both include a quick-change male joint and a quick-change female joint; the quick-change male joint has a first flange and a first tube body connected to the first flange, the first flange is connected to the discharge interface flange, the first tube body is arranged on the side of the first flange away from the discharge interface flange, the first anti-foolproof male joint and the second anti-foolproof male joint are connected to the first tube bodies of the two quick-change male joints in a one-to-one manner; the quick-change female joint has a second flange and a second tube body connected to the second flange, the second flange is connected to the collection interface flange, the second tube body is arranged on the side of the second flange away from the collection interface flange, the first anti-foolproof female joint and the second anti-foolproof female joint are connected to the second tube bodies of the two quick-change female joints in a one-to-one manner.
[0021] In an alternative embodiment, the first anti-fool male connector has a third flange and a first disc. The third flange and the first disc are connected by a first bracket, and the third flange is connected to the first flange of one of the quick-change male connectors; the first anti-fool female connector has a fourth flange and a second disc. The fourth flange and the second disc are connected by a second bracket, and the fourth flange is connected to the second flange of one of the quick-change female connectors; when the first disc is connected to the second disc, the first pipe body extends into the second pipe body and is hermetically connected to the second pipe body; and / or, the second anti-fool male connector has a fifth flange and a third disc. The fifth flange and the third disc are connected by a third bracket, and the fifth flange is connected to the first flange of the other quick-change male connector; the second anti-fool female connector has a sixth flange and a fourth disc. The sixth flange and the fourth disc are connected by a fourth bracket, and the sixth flange is connected to the second flange of the other quick-change female connector; when the third disc is connected to the fourth disc, the first pipe body extends into the second pipe body and is hermetically connected to the second pipe body.
[0022] In the above implementation process, a quick-change male connector can be connected to each of the two discharge interface flanges, so that the waste liquid of the liquid discharge machine table can flow into the first pipe body. Similarly, a quick-change female connector is connected to each of the two collection interface flanges, so that the waste liquid in the second pipe body of the quick-change female connector can flow into the collection machine table. When the first anti-fool male connector at the quick-change male connector is connected to the first anti-fool female connector at the quick-change female connector, the first pipe body can extend into the second pipe body to convey the waste liquid from the discharge machine table to the second pipe body through the first pipe body and then flow into the corresponding collection machine table. Similarly, when the second anti-fool male connector at the quick-change male connector is connected to the second anti-fool female connector at the quick-change female connector, the first pipe body can extend into the second pipe body to convey the waste liquid from the discharge machine table to the second pipe body through the first pipe body and then flow into the corresponding collection machine table. Different first anti-fool components and second anti-fool components are provided between the two groups of quick-change male connectors and quick-change female connectors, which can prevent misconnection.
[0023] In an alternative embodiment, the discharge interface flange is connected to the liquid discharge machine table through a hose; and / or, the collection interface flange is connected to the collection machine table through a hose.
[0024] In the above implementation process, the discharge interface flange is connected to the liquid discharge machine table through a hose, or the collection interface flange is connected to the collection machine table through a hose, so as to facilitate the connection between the liquid discharge machine table and the collection machine table.

[0040] In the industrial production process, it is usually necessary to transport the waste liquid generated after the machine production to the collection machine for collection. Moreover, in order to improve production efficiency, multiple identical liquid discharge machines and collection machines are usually set up in the workshop. However, since the interfaces of each liquid discharge machine and collection machine are the same, during the actual operation, the operator is prone to mix up the connectors, resulting in the chemicals in the collection machine being mixed, which is not convenient for later maintenance.
[0041] Therefore, this application provides a liquid discharge system, which can, to a certain extent, improve the problem of waste liquid mixing caused by the wrong connection of connectors. To make the purpose, technical solutions and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the drawings in the embodiments of this application.
[0042] Please refer to Figure 1, the drainage system provided by the example of this application includes at least two sets of corresponding drainage machine platforms 10 and collection machine platforms 20.
[0043] Among them, each drainage machine platform 10 is provided with a discharge interface flange, and each collection machine platform 20 is provided with a collection interface flange.
[0044] Furthermore, for the convenience of connection, in some possible embodiments, the discharge interface flange can be connected to the drainage machine platform 10 through a hose.
[0045] Furthermore, the collection interface flange is connected to the collection machine platform 20 through a hose.
[0046] Hereinafter, for the convenience of distinction, the two sets of corresponding drainage machine platforms and collection machine platforms are respectively named the first drainage machine platform and the first collection machine platform, the second drainage machine platform and the second collection machine platform. As Figure 1 shown, the first drainage machine platform is provided with a first discharge interface flange 11, and the second drainage machine platform is provided with a second discharge interface flange 12; the first collection machine platform is provided with a first collection interface flange 21, and the second collection machine platform is provided with a second collection interface flange 22.
[0047] The drainage system provided by the example of this application further includes a first anti-fooling joint assembly 30 and a second anti-fooling joint assembly 40.
[0048] Among them, please refer to Figure 2 and Figure 3 , the first anti-fooling joint assembly 30 includes a first anti-fooling male joint 31 respectively connected to the first discharge interface flange 11, and a first anti-fooling female joint 32 connected to the first collection interface flange 21. The first anti-fooling male joint 31 and the first anti-fooling female joint 32 are detachably connected through a first fitting 33, so that the waste liquid of the first drainage machine platform can flow into the first collection machine platform through the first anti-fooling joint assembly 30.
[0049] Among them, please refer to Figure 2 and Figure 4 , the second anti-fooling joint assembly 40 includes a second anti-fooling male joint 41 respectively connected to the second discharge interface flange 12, and a second anti-fooling female joint 42 connected to the second collection interface flange 22. The second anti-fooling male joint 41 and the second anti-fooling female joint 42 are detachably connected through a second fitting 43, so that the waste liquid of the second drainage machine platform can flow into the second collection machine platform through the second anti-fooling joint assembly 40.
[0050] Since the first fitting 33 and the second fitting 43 are different, the first anti-fooling male joint 31 cannot be connected to the second anti-fooling female joint 42, and the waste liquid of the first drainage machine platform cannot be discharged into the second collection machine platform. Similarly, the second anti-fooling male joint 41 cannot be connected to the first anti-fooling female joint 32, and the waste liquid of the second drainage machine platform cannot be discharged into the first collection machine platform.
[0051] Furthermore, in order to facilitate the connection between the first foolproof joint assembly 30 and the second foolproof joint assembly 40 and the corresponding machine, in some possible embodiments, the drainage system is further provided with two sets of quick-change male joints and quick-change female joints. For the sake of distinction, they are hereinafter referred to as the first quick-change male joint 51, the first quick-change female joint 52, the second quick-change male joint 53, and the second quick-change female joint 54.

The second flange 57 is connected to the collection interface flange. The second tube body 58 is arranged on the side of the second flange 57 away from the collection interface flange. The first fool-proof female connector 32 and the second fool-proof female connector 42 are connected to the second tube bodies 58 of the two quick-change female connectors in a one-to-one correspondence.
[0055] For further information, please refer to Figure 3 A first disc 311 is provided at one end of the first anti-foolproof male connector 31 which faces away from the discharge interface flange, and a second disc 321 is provided at one end of the first anti-foolproof female connector 32 which faces away from the collection interface flange; the first mating piece 33 includes a first connecting hole 331 provided at the second disc 321 and a first connecting piece 332 provided at the first disc 311, and the first connecting piece 332 is detachably connected to the first connecting hole 331.

[0057] Further, in order to facilitate the connection between the anti-fool connector assembly and the quick-release connector, in some possible embodiments, please refer to Figure 5 , the first anti-fool male connector 31 has a third flange 312 and a first disc 311, the third flange 312 and the first disc 311 are connected by a first bracket 313, and the third flange 312 is connected to the first flange 55 of the first quick-release male connector 51. The first anti-fool female connector 32 has a fourth flange 322 and a second disc 321, the fourth flange 322 and the second disc 321 are connected by a second bracket 323, and the fourth flange 322 is connected to the second flange 57 of the first quick-release female connector 52. When the first disc 311 is connected to the second disc 321, the first pipe body 56 extends into the second pipe body 58 and is hermetically connected to the second pipe body 58 to convey the waste liquid of the first liquid discharge machine to the first collection machine.
[0058] Further, please refer to Figure 7 , the second anti-fool male connector 41 has a fifth flange 412 and a third disc 411, the fifth flange 412 and the third disc 411 are connected by a third bracket 413, and the fifth flange 412 is connected to the first flange 55 of the second quick-release male connector 53. The second anti-fool female connector 42 has a sixth flange 422 and a fourth disc 421, the sixth flange 422 and the fourth disc 421 are connected by a fourth bracket 423, and the sixth flange 422 is connected to the second flange 57 of the second quick-release female connector 54. When the third disc 411 is connected to the fourth disc 421, the first pipe body 56 extends into the second pipe body 58 and is hermetically connected to the second pipe body 58 to convey the waste liquid of the second liquid discharge machine to the second collection machine.
[0059] Exemplarily, the first bracket 313, the second bracket 323, the third bracket 413, and the fourth bracket 423 each include a plurality of spaced connecting plates, and both ends of the connecting plates are respectively connected to the corresponding flange and disc.
[0060] Exemplarily, for the convenience of connection, the first connecting member 332 and the second connecting member 432 can both be set as studs, and the first connection hole 331 and the second connection hole 431 can both be set as threaded holes.
[0061] In order to avoid misconnection, in the liquid discharge system provided by the example of the present application, the second connecting member 432 cannot be connected to the first connection hole 331, and the first connecting member 332 cannot be connected to the second connection hole 431.
[0062] Exemplarily, refer to Figure 6 , a plurality of first connection holes 331 may be provided at circumferentially uniform intervals on the second disk 321, and there is a first interval angle α1 between every two adjacent first connection holes 331. Then, a plurality of first connection members 332 are provided at circumferentially uniform intervals on the first disk 311, and the interval angle between every two adjacent first connection members 332 is the first interval angle α1.
[0063] Refer to Figure 8 , a plurality of second connection holes 431 are provided at circumferentially uniform intervals on the fourth disk 421, and there is a second interval angle α2 between every two adjacent second connection holes 431. Then, a plurality of second connection members 432 are provided at circumferentially uniform intervals on the third disk 411, and the interval angle between every two adjacent second connection members 432 is the second interval angle α2. The first interval angle α1 is different from the second interval angle α2 and is not an even multiple.
[0064] Since the first interval angle α1 is different from the second interval angle α2 and is not an even multiple, therefore, no first connection hole 331 is provided at the position of the second connection member 432 of the third disk 411 corresponding to the second disk 321. So, the plurality of second connection members 432 of the third disk 411 cannot extend into the first connection holes 331 of the second disk 321 one by one, and the second disk 321 and the third disk 411 cannot be connected.
[0065] Similarly, no second connection hole 431 is provided at the position of the fourth disk 421 corresponding to the first connection member 332 of the first disk 311. So, the plurality of first connection members 332 of the first disk 311 cannot extend into the second connection holes 431 of the fourth disk 421 one by one, and the fourth disk 421 and the first disk 311 cannot be connected.
[0066] Exemplarily, the first interval angle α1 is 90° and the second interval angle α2 is 60°.
[0067] Or, in some other possible embodiments, a plurality of first connection holes 331 are provided at circumferentially uniform intervals on the second disk 321, and a plurality of second connection holes 431 are provided at circumferentially uniform intervals on the fourth disk 421, and the diameter of the first connection hole 331 is different from the diameter of the second connection hole 431.
[0068] Exemplarily, the inner diameter of the first connection hole 331 is 10 mm, then the outer diameter of the first connection member 332 is 10 mm; the inner diameter of the second connection hole 431 is 20 mm, then the outer diameter of the second connection member 432 is 20 mm.
[0069] Alternatively, in some other possible embodiments, a plurality of first connection holes 331 may be provided at non-uniform circumferential intervals on the second disc 321, and a plurality of second connection holes 431 may be provided at non-uniform circumferential intervals on the fourth disc 421, and a first interval angle α1 between two adjacent first connection holes 331 is different from a second interval angle α2 between two adjacent second connection holes 431.
