[0030] In the following, specific embodiments are combined with the description Figures 1-5To illustrate the technical solutions of the present application in detail.

[0031] In view of this, as Figures 1-5 shown, the present application provides a liquid draining and cleaning system, comprising: a main pipeline 1, one end of which is used to communicate with a positive pressure power source A, and the other end of which is used to communicate with an inlet end of a bin pipeline 41, and a plurality of waste liquid collection cups 42 are further communicated on the bin pipeline 41; a liquid draining device 2, comprising a waste liquid storage tank 109 and a liquid return pipeline 1090, one end of the liquid return pipeline 1090 is communicated with the waste liquid storage tank 109, and the other end is used to communicate with an outlet end of the bin pipeline 41, and the waste liquid storage tank 109 is further communicated with a negative pressure power source B, so that under the action of negative pressure provided by the negative pressure power source B, the waste liquid in the waste liquid collection cup 42 is sucked into the bin pipeline 41, and under the action of positive pressure provided by the positive pressure power source A, the waste liquid in the bin pipeline 41 is pressed into the waste liquid storage tank 109 through the liquid return pipeline 1090; a cleaning device 3, comprising a cleaning liquid storage tank 1102, which is communicated with the main pipeline 1, so that under the action of negative pressure provided by the negative pressure tool of the bin pipeline 41, the cleaning liquid in the cleaning liquid storage tank 1102 is sucked into the bin pipeline 41 through the main pipeline 1, and under the action of positive pressure provided by the positive pressure power source A, the cleaning liquid in the bin pipeline 41 is pressed into the waste liquid storage tank 109 through the liquid return pipeline 1090.

[0032] Specifically, for example, the positive pressure power source A can be a breathing machine, an air compressor, a gas source device, etc., and the positive pressure power is generated by a compressor or an air pump inside the breathing machine, the air compressor, the gas source device, etc. The negative pressure power source B can be a negative pressure device, and the negative pressure power source B is generated by components such as a motor, a transmission system and a compression system. As Figure 1As shown, the main pipeline 1 is in communication with the inlet end of the library pipeline 41, and a plurality of waste liquid collection cups 42 are also in communication with the library pipeline 41. It can be seen that the main pipeline 1 is used to collect the waste liquid in the waste liquid collection cup 42. The waste liquid return port 1093 of the waste liquid storage tank 109 in the liquid discharge device 2 is connected with one end of the waste liquid return pipeline 1090, and the other end of the waste liquid return pipeline 1090 is in communication with the outlet end of the library pipeline 41. The negative pressure power source B is connected with the interface of the negative pressure power source B. Under the action of the negative pressure provided by the negative pressure power source B, the waste liquid in the waste liquid collection cup 42 is sucked into the library pipeline 41, and under the action of the positive pressure provided by the positive pressure power source A, the waste liquid in the library pipeline 41 is pressed into the waste liquid storage tank 109 through the waste liquid return pipeline 1090. When there is waste liquid in the library pipeline 41, the waste liquid is collected under the action of the positive pressure of the positive pressure power source A, and under the cooperation of the positive pressure power source A and the negative pressure power source B, the automatic liquid discharge function of the waste liquid is realized, the manual participation is reduced, and the manpower is saved. The cleaning liquid storage tank 1102 in the cleaning device 3 is used to store cleaning liquid, and the cleaning liquid storage tank 1102 is in communication with the main pipeline 1. Under the action of the negative pressure provided by the negative pressure tool of the library pipeline 41, the cleaning liquid in the cleaning liquid storage tank 1102 is sucked into the library pipeline 41 through the main pipeline 1, and then enters the library 4 through the library pipeline 41 to clean the library 4. After cleaning, the cleaning liquid in the library 4 is sucked into the library pipeline 41 under the action of the positive pressure provided by the positive pressure power source A, the cleaning liquid in the waste liquid collection cup 42 is sucked into the library pipeline 41 under the action of the negative pressure provided by the negative pressure power source B, and the cleaning liquid in the library pipeline 41 is pressed into the waste liquid storage tank 109 through the waste liquid return pipeline 1090 under the action of the positive pressure provided by the power source. The cleaning liquid is cleaned, that is, the functions of automatically cleaning the library 4 and discharging the cleaning liquid are realized by the cleaning device 3. Through the system, the automatic liquid discharge and cleaning of the library 4 are realized, the problem of frequent human intervention is reduced, and the labor cost is saved.

[0033] In some embodiments, as shown in Figure 1 , Figure 3 and Figure 4 , under the action of the negative pressure provided by the negative pressure power source B, the waste liquid in the library pipeline 41 is sucked into the waste liquid storage tank 109. Since the waste liquid storage tank 109 is a sealed tank, air pressure is generated, so a waste liquid exhaust port 1092 is arranged on the waste liquid storage tank 109 to realize the exhaust of the gas in the waste liquid storage tank 109. Further, the system further comprises an exhaust pipeline 1051, one end of the exhaust pipeline 1051 is in communication with the top of the waste liquid storage tank 109, and the other end is connected with the waste gas treatment equipment C.

[0034] Specifically, in order to facilitate the wiring of the pipeline, and also to avoid damaging the waste liquid storage tank 109, the waste liquid exhaust port 1092 is arranged on the tank cover at the top of the waste liquid storage tank 109, so that one end of the exhaust pipeline 1051 is connected with the waste liquid exhaust port 1092 at the top of the waste liquid storage tank 109, and the other end of the exhaust pipeline is connected with the waste gas treatment device C, for exhausting the gas in the waste liquid storage tank 109 into the waste gas treatment device C, so as to ensure the stable operation of the waste liquid storage tank 109 and the safety of the environment.

[0035] In some embodiments, as shown in Figure 2 and Figure 3 to avoid frequent manual participation, the system further comprises a controller 202, the main pipeline 1 is provided with a positive pressure valve 107, the connecting pipeline between the waste liquid storage tank 109 and the negative pressure power source B is provided with a negative pressure valve 106, and the exhaust pipeline 1051 is provided with an exhaust valve 105, and the controller 202 is electrically connected with the positive pressure valve 107, the negative pressure valve 106 and the exhaust valve 105.

[0036] Specifically, in order to realize the automatic function of the system, the positive pressure valve 107, the negative pressure valve 106 and the exhaust valve 105 are all solenoid valves, and the controller 202 is used to control the on-off of the positive pressure valve 107, the negative pressure valve 106 and the exhaust valve 105. The main pipeline 1 is provided with the positive pressure valve 107, that is, the positive pressure valve 107 is used to control the positive pressure in the main pipeline 1. The connecting pipeline between the waste liquid storage tank 109 and the negative pressure power source B is provided with the negative pressure valve 106, that is, the negative pressure valve 106 is used to control the negative pressure in the waste liquid storage tank 109. The exhaust pipeline 1051 is provided with the exhaust valve 105, that is, the exhaust valve 105 is used to control the gas pressure in the waste liquid storage tank 109. Through the control of the positive pressure valve 107, the negative pressure valve 106 and the exhaust valve 105, the automatic liquid discharge function in the warehouse position 4 can be realized under the cooperation of the positive pressure power source A and the negative pressure power source B, and the discharged liquid can be discharged into the waste liquid storage tank 109, thereby avoiding frequent manual participation and saving manpower.

[0037] In some embodiments, when the waste liquid storage tank 109 is used for a long time, resulting in insufficient storage space, or when the cleaning liquid storage tank 1102 is cleaned, the system further comprises a waste liquid bucket 112, which is in communication with the waste liquid storage tank 109 and the cleaning liquid storage tank 1102, respectively. By connecting the waste liquid bucket 112 with the waste liquid storage tank 109 and the cleaning liquid storage tank 1102, the waste liquid in the waste liquid storage tank 109 and the cleaning liquid in the cleaning liquid storage tank 1102 can be discharged into the waste liquid bucket 112 for storage, thereby realizing the storage of waste liquid and cleaning liquid in two places, avoiding the problem of frequent cleaning of waste liquid and cleaning liquid, and further reducing the frequent manual participation.

[0038] Further, a liquid level sensor can also be arranged on the waste liquid barrel 112 to monitor the liquid level of the waste liquid barrel 112, the liquid level sensor is electrically connected with the controller 202, and the controller 202 can acquire the liquid level sensor signal in real time; when it is detected that the storage space of the waste liquid barrel 112 is insufficient, the controller 202 can prompt the staff to clean up through sound alarm or control the warning light 201. In the embodiment, the warning light 201 is arranged on the installation cabinet 01 of the system, and the warning light 201 is electrically connected with the controller 202; for example, the warning light 201 can be arranged on the top of the installation cabinet 01, or can be arranged on the side wall of the installation cabinet 01, which is not limited in the utility model. When the staff sees the prompt, the waste liquid in the waste liquid barrel 112 can be cleaned up through the transfer trolley 111. Figure 2 As shown, the waste liquid in the waste liquid barrel 112 can be cleaned up through the transfer trolley 111.

[0039] In some embodiments, as shown in Figure 3 and Figure 4 In order to detect the liquid storage condition of the waste liquid storage tank 109 in real time, a liquid level observation sensor 1095 is arranged on the outer side wall of the waste liquid storage tank 109; the liquid level observation sensor 1095 is electrically connected with the controller 202, the liquid level observation sensor 1095 detects the liquid storage position in the storage tank in real time, and feeds back the detected data to the controller 202, and the controller 202 can display the detected data in the form of a display screen, for example, a display screen is arranged on the end face of the installation cabinet 01, and the display screen is used for some data in the working process of the system, which includes the liquid storage position of the waste liquid storage tank 109, so as to clean the waste liquid storage tank 109.

[0040] In some embodiments, as shown in Figure 3 and Figure 4 Based on the above embodiment, the waste liquid storage tank 109 is communicated with the waste liquid barrel 112, when the storage space in the waste liquid storage tank 109 is insufficient, in order to release the storage space, the waste liquid in the waste liquid storage tank 109 is discharged into the waste liquid barrel 112, so it can be known that the valve is needed to control between the waste liquid storage tank 109 and the waste liquid barrel 112, therefore, a first control valve 1096 is arranged on the pipeline between the waste liquid storage tank 109 and the waste liquid barrel 112; the flow through of the pipeline between the waste liquid storage tank 109 and the waste liquid barrel 112 can be controlled through the first control valve 1096. In the embodiment, the first control valve 1096 can be an electromagnetic valve or a manual valve.

[0041] In some embodiments, as shown in Figure 3 and Figure 5As shown, based on the above embodiment, the cleaning liquid storage tank 1102 is communicated with the waste liquid tank 112. When the cleaning liquid storage tank 1102 is used for a long time, the cleaning liquid storage tank 1102 needs to be cleaned, or the cleaning liquid needs to be replaced when the cleaning liquid is used for a long time. The cleaning liquid in the cleaning liquid storage tank 1102 needs to be discharged into the waste liquid tank 112. Therefore, the cleaning liquid and the waste liquid tank 112 need to be controlled by a valve. Therefore, a second control valve 1106 is arranged on the pipeline between the cleaning liquid storage tank 1102 and the waste liquid tank 112. The second control valve 1106 is arranged at the cleaning liquid discharge port 1105 of the cleaning liquid storage tank 1102. The second control valve 1106 can control the pipeline flow between the cleaning liquid storage tank 1102 and the waste liquid tank 112. In this embodiment, the second control valve 1106 can be an electromagnetic valve or a manual valve.

[0042] In some embodiments, the system includes a liquid discharge device 2 and a cleaning device 3. In order to save space, the liquid discharge device 2 and the cleaning device 3 can be integrated together. Specifically, the system further includes a mounting cabinet 01. The mounting cabinet 01 includes a first mounting space 011 and a second mounting space 012 arranged adjacent to each other. The waste liquid storage tank 109, the cleaning liquid storage tank 1102, and the waste liquid tank 112 are located in the first mounting space 011. The controller 202 is located in the second mounting space 012.

[0043] Specifically, as Figure 2As shown, the exemplary installation cabinet 01 is provided with four supporting feet at the bottom, which can also be adjusted in height to adapt to different environments. When the environment is humid, the installation cabinet 01 can be adjusted to a higher position to avoid being damp. The installation cabinet 01 includes a first installation space 011 and a second installation space 012 arranged adjacent to each other. The first installation space 011 is used to install the integrated liquid discharge device 2 and the cleaning device 3, and the second installation space 012 is used to install the control system, so as to realize isolated installation of the control system and the specific devices and ensure the safety of the control system. That is, the waste liquid tank 109 of the liquid discharge device 2, the cleaning liquid tank 1102 of the cleaning device 3, and the waste liquid barrel 112 for collecting the liquid in the waste liquid tank 109 and the cleaning liquid tank 1102 are arranged in the first installation space 011, and the controller 202 is arranged in the second installation space 012. The installation cabinet 01 is provided with cabinet doors corresponding to the first installation space 011 and the second installation space 012. The cabinet door corresponding to the first installation space 011 is a cabinet door with an opening and closing structure, which facilitates the opening of the cabinet door to clean the internal waste liquid barrel 112 or observe the running state of each tank. The cabinet door corresponding to the second installation space 012 can be a fixed cabinet door, which installs the control system in the fixed cabinet door to avoid the circuit inside the control system from being damp. A plurality of notches are formed on the cabinet door, which are used to install a display screen or control switches. The display screen and the control switches are connected with the controller 202 inside to realize the control of the integrated liquid discharge device 2 and the cleaning device 3.

[0044] Further, when the waste liquid tank 109, the cleaning liquid tank 1102 of the cleaning device 3, and the waste liquid barrel 112 for collecting the liquid in the waste liquid tank 109 and the cleaning liquid tank 1102 are arranged in the first installation space 011, the pipelines between each tank and the waste liquid barrel 112 can be routed according to the specific space position. When connected with external equipment (such as the library pipeline 41, the positive pressure power source A, and the negative pressure power source B), corresponding through holes are formed on the cabinet wall of the installation cabinet 01 to facilitate the routing of each pipeline.

[0045] In some embodiments, based on the above-mentioned embodiments, the first installation space 011 is used to install the integrated liquid discharge device 2 and the cleaning device 3. In order to reasonably divide the space, a first partition frame 011a and a second partition frame 011b connected with each other are further arranged in the first installation space 011. The waste liquid tank 109 is located above the first partition frame 011a, and the cleaning liquid tank 1102 is located in the second partition frame 011b.

[0046] Specifically, as Figure 3As shown, the first partition frame 011a and the second partition frame 011b in the first installation space 011 are adjacent and staggered, the first partition frame 011a is arranged in close contact with the inner wall of the installation cabinet 01, so that the stability of the first partition frame 011a can be ensured, and the waste liquid storage tank 109 is arranged on the first partition frame 011a, so that the installation stability of the waste liquid storage tank 109 can be ensured. The second partition frame 011b is arranged adjacent to the cabinet door, and the cleaning liquid storage tank 1102 is arranged in the second partition frame 011b. Since the cleaning liquid inlet 1101 is arranged on the top of the cleaning liquid storage tank 1102, the cleaning liquid inlet 1101 is arranged adjacent to the cabinet door, so that workers can conveniently add cleaning liquid.

[0047] Further, since the cleaning liquid storage tank 1102 is a sealed tank, gas will be generated in the cleaning liquid storage tank 1102 when cleaning liquid is added, so that the cleaning liquid exhaust port 1103 is arranged on the top of the cleaning liquid storage tank 1102, the cleaning liquid exhaust port 1103 is connected with the exhaust pipeline 1051, and waste gas is discharged to the waste gas treatment equipment C.

[0048] In some embodiments, as shown in Figure 3 and Figure 5 Based on the above embodiment, the cleaning tank of the cleaning device 3 is communicated with the main pipeline 1, under the negative pressure provided by the negative pressure tooling of the storage site pipeline 41, the cleaning liquid in the cleaning liquid storage tank 1102 is sucked into the storage site pipeline 41 through the main pipeline 1, in order to avoid that the waste liquid in the storage site pipeline 41 flows into the cleaning liquid storage tank 1102, therefore, the third control valve 1107 is arranged on the pipeline between the cleaning liquid storage tank 1102 and the main pipeline 1, the third control valve 1107 is used to control the on-off between the cleaning liquid storage tank 1102 and the main pipeline 1, so as to avoid that the waste liquid in the main pipeline 1 flows back into the cleaning liquid storage tank 1102. The third control valve 1107 can be an electromagnetic valve or a manual valve.

[0049] The specific use process of the liquid drainage and cleaning system is as follows:

[0050] The waste liquid storage tank 109 is connected to the main pipeline 1, and the main pipeline 1 is connected to the library pipeline 41 of the library 4. After the connection is completed, the system can be operated on the display screen to clean and drain the library 4. When the waste liquid in the library 4 needs to be drained, the controller 202 controls the negative pressure valve 106 to open, and starts the negative pressure power source B, so that the negative pressure is formed in the waste liquid storage tank 109 to suck the waste liquid in the waste liquid collection cup 42 in the library 4 into the library pipeline 41. The negative pressure valve 106 is closed, and the positive pressure valve 107 is opened. The positive pressure power source A controls the waste liquid in the library pipeline 41 to be pressed into the waste liquid storage tank 109 through the main pipeline 1. After the positive pressure valve 107 is opened for a certain time (for example, the certain time is 5S), the exhaust valve 105 is opened to ensure that the waste liquid storage tank 109 normally receives the waste liquid, and to avoid that the pressure in the waste liquid storage tank 109 is too large to cause harm. Each library 4 can be controlled independently. Valves are added at the library pipeline 41 of each library 4 to achieve control. The specific setting is determined according to the actual situation, which is not limited in the present application. Multiple cycles of extraction can be achieved in the present application. When the library 4 needs to be cleaned, the third control valve 1107 is opened. The negative pressure tool in the library 4 provides negative pressure. Under the action of the negative pressure, the cleaning liquid in the cleaning liquid storage tank 1102 is sucked into the library 4 through the library pipeline 41 and the main pipeline 1 to clean the library 4. After the cleaning is completed, the negative pressure valve 106 is opened by the controller 202, and the negative pressure power source B is started, so that the negative pressure is formed in the waste liquid storage tank 109 to suck the cleaning liquid in the library 4 into the library pipeline 41. The negative pressure valve 106 is closed, and the positive pressure valve 107 is opened. The positive pressure power source A controls the cleaning liquid in the library pipeline 41 to be pressed into the waste liquid storage tank 109 through the main pipeline 1. After the positive pressure valve 107 is opened for a certain time (for example, the certain time is 5S), the exhaust valve 105 is opened.

[0051] When it is detected that the capacity of the waste liquid storage tank 109 is insufficient, the waste liquid in the waste liquid storage tank 109 needs to be released and drained into the waste liquid barrel 112. The first control valve 1096 is opened to drain the liquid in the waste liquid storage tank 109 into the waste liquid barrel 112.

[0052] When the cleaning device 3 needs to be cleaned, the cleaning liquid is added into the cleaning liquid storage tank 1102 through the cleaning liquid inlet 1101. During this process, the exhaust valve 105 is opened, and then the second control valve 1106 is opened after being stationary for a certain time to drain the cleaning liquid into the waste liquid barrel 112.

[0053] It should be understood by those of ordinary skill in the art that the above discussion of any embodiment is merely exemplary and is not intended to suggest that the scope (including claims) of the present application is limited to these examples; the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other changes of the aspects of the present application as described above. In order to be brief, they are not provided in detail.

[0054] It is intended that the embodiments of the application cover all such alternatives, modifications, and variations as come within the scope of the appended claims. Accordingly, all such alternatives, modifications, and variations should be included within the scope of the application.
