Abstract
Description
Technical Field
[0001] This application relates to the field of live virus wastewater treatment technology, and in particular to a disinfection collection tank used in live virus wastewater drainage pipes that are P-shaped connected and coplanar. Background Technology
[0002] Wastewater from biosafety experiments is called live-virus wastewater, which refers to wastewater generated from experiments, production, and other activities involving pathogenic microorganisms. In high-level biosafety laboratory environments, the proper handling of live-virus wastewater is crucial, as leaks of pathogen-containing live-virus wastewater can pose a serious threat to human health and environmental safety.
[0003] The biosafety wastewater discharge pipe is used to transport biosafety wastewater to the biosafety wastewater treatment device. During the installation process, in order to meet the requirements of laboratory biosafety and on-site installation, in some areas, adjacent biosafety wastewater discharge pipes are directly connected by welding; while in other areas, they are connected by welding to the biosafety wastewater discharge pipes using elbows.
[0004] Because disinfectants are corrosive, leaks are highly likely to occur at elbows and welds. Safely locating these leak-prone areas and immediately disinfecting the leaked toxic wastewater to minimize harm and subsequently repair the leak has always been a pursuit of those skilled in the art.
[0005] However, the existing technology for dealing with the leakage of live toxic wastewater has the following problem: there is a lack of a device to directly disinfect the leak after detecting the location of the leak. As a result, even if the detection device detects the leak, the staff cannot deal with the leak in a timely and effective manner. Therefore, the existing live toxic wastewater drainage pipes pose a biosafety risk, especially at some bends and welds.
[0006] Based on extensive research, the applicant has proposed a high-level biosafety laboratory live virus wastewater drainage pipe leakage monitoring and spray disinfection control system, and has applied for an invention patent on the same day. The system can effectively and promptly handle leakage from live virus wastewater drainage pipes. The system involves the centralized treatment of leakage in a disinfection collection tank during operation. However, since live virus wastewater drainage pipes are often pre-installed according to production needs and geographical location, the disinfection collection tank in the aforementioned spray disinfection control system, which is installed subsequently, must be specifically adapted to the specific installation of the live virus wastewater drainage pipe.
[0007] Typically, the connection between two live toxic wastewater drainage pipes can be in the following ways: the two pipes are connected in a straight line, the two pipes are connected in a P-shape and are on the same plane, or the two pipes are connected in a P-shape but are not on the same plane, and are in an skewed shape.
[0008] Therefore, after the live toxic sewage drainage pipe is installed, how to design a corresponding disinfection collection tank according to the different connection methods of the pipe so that it can be adapted to the live toxic sewage drainage pipe to facilitate disinfection operations, and at the same time, under the premise that the disinfection collection tank is adapted to the live toxic sewage drainage pipe, how to achieve quick disassembly and assembly of the disinfection collection tank from the live toxic sewage drainage pipe so as to meet the needs of recycling are technical problems faced by those skilled in the art.

While embodiments of this application are shown in the examples, it should be understood that this application can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make this application more thorough and complete, and to fully convey the scope of this application to those skilled in the art.
[0021] like Figure 1 As shown, a disinfection collection tank for a live toxic wastewater drainage pipe connected in a P-shape and coplanar manner in this application includes a hollow hexahedral body 100, the body of which has an internal cavity; the body of the tank 100 includes a movable top plate 1 and a movable side plate 2 adjacent to the movable top plate. The movable top plate 1 includes a fixed top plate 10 and a movable top plate 11. The fixed top plate 10 has a first arc-shaped opening 12, and the movable top plate 11 has a second arc-shaped opening 13.

The movable side plate 2 includes a movable side plate body 21 and a fixed side plate body 20. The movable side plate body 21 is provided with a third arc-shaped opening 22, and the fixed side plate body 20 is provided with a fourth arc-shaped opening 23. The third arc-shaped opening 22 and the fourth arc-shaped opening 23 are arranged opposite to each other and together form a closed hole for accommodating the second live toxic sewage drain pipe. The top movable plate 11 and the side movable plate 21 are arranged adjacent to each other and perpendicularly, and the top of the side movable plate 21 abuts against the lower end face of the top movable plate 11. This application employs a specially designed movable top plate and movable side plates. The movable top plate includes a movable top plate body, and the movable side plates include movable side plate bodies. The movable top plate bodies and movable side plate bodies are adjacent to each other and arranged perpendicularly, with the top of the movable side plate body abutting against the lower end face of the movable top plate body. When the main body of the box in this application needs to be installed at the location where two live toxic wastewater drainage pipes, namely the first live toxic wastewater drainage pipe 200 and the second live toxic wastewater drainage pipe 300, are connected in a P-shape, such as... Figure 3 and Figure 5 As shown, simply open the top panel and the side panel, and then install them. After the P-shaped connection is completed, the box can be quickly closed using the top panel and the side panel.
[0022] Specifically, in this embodiment, the two live-poisoned wastewater drainage pipes, namely the first live-poisoned wastewater drainage pipe 200 and the second live-poisoned wastewater drainage pipe 300, are connected in a P-shape. (See the detailed structural diagram below.) Figure 4 As shown, in Figure 4 The first toxic wastewater drain pipe 200 and the second toxic wastewater drain pipe 300 are connected by three elbows. Of course, in actual application, after connecting with elbows 400, further welding is required at the connection point.
[0023] Furthermore, such as Figure 2 As shown, sealing strips 3 are provided at the outer circumferential surfaces of the top plate movable plate 11 and the side plate movable plate 21, at the positions of the first arc-shaped opening 12 and the fourth arc-shaped opening 23; and base strips 5 are fixedly connected to the side plate fixed body 20 and the opposite side plates on both sides of the main body of the box below the movable top plate 1, with several blind hole nuts pre-embedded in the base strips 5; the top plate movable plate 11 and the side plate movable plate 21 are fastened to the sealing strips 3 and the base strips 5 respectively through the blind hole nuts with corresponding screws 6. The above structure design can fully ensure the sealing performance between the top plate movable plate 11 and the side plate movable plate 21 and the rest of the main body of the box.
[0024] Furthermore, to improve structural stability, fastening structures 4 are provided between the fixed top plate 10 and the movable top plate 11, and between the movable side plate 21 and the fixed side plate 20. Preferably, the fastening structure 4 is an adjustable latch.
[0025] Furthermore, the main body 100 of the box is made of acrylic material. This is not only inexpensive, but also facilitates observation of the interior of the main body 100 of the box.
[0026] Furthermore, the main body 100 of the box is provided with a drain hole, a spray hole, a water leakage monitoring cable through hole, a spray disinfection exhaust hole, a gas disinfection inlet hole and a gas disinfection exhaust hole, and a connector 7 is provided for each of the drain hole, spray disinfection exhaust hole, spray hole, gas disinfection inlet hole and gas disinfection exhaust hole; a cable connector 8 is provided for each of the water leakage monitoring cable through hole.
[0027] A drain pipe with a valve is connected to the connector corresponding to the drain hole; An exhaust pipe is connected to the connector corresponding to the exhaust port of the spray disinfection system. A solenoid valve is connected to the exhaust pipe, and a high-efficiency filter is connected to the end of the exhaust pipe. Spray pipes are connected to both ends of the connector corresponding to the spray hole. The end of the spray pipe facing the inner side of the main body of the box is connected to a spray head, and the end of the spray pipe facing the outer side of the main body of the box is connected to a disinfectant storage tank. An electric ball valve, a water pump and a pre-filter are installed on the spray pipe in sequence.
[0028] The leak detection cable perforation is for the leak detection cable to pass through; Specifically, a leakage detection system is used to detect leaks in the live toxic wastewater drainage pipe. The leakage detection system includes a leakage monitoring cable and a leakage monitoring controller. The leakage monitoring cable is wound around the outer surface of the section of the live toxic wastewater drainage pipe to be monitored for leakage and is electrically connected to the leakage monitoring controller. During operation, the leakage monitoring cable feeds back the leakage signal of the detected leakage section of the live toxic wastewater drainage pipe to the leakage monitoring controller, which then feeds back the feedback signal to the network controller. Then, an audible and visual alarm unit is used to generate an audible and visual alarm signal command based on the leakage signal received by the network controller.
[0029] Maintenance personnel activate the spray control system to perform spray disinfection operations based on audible and visual alarm signals. Specifically, the spray control system includes a disinfectant storage tank, a water pump, an electric ball valve, a spray pipe, a spray head, and a solenoid valve. The disinfectant storage tank, water pump, electric ball valve, and spray pipe are connected in sequence. The spray pipe extends through one side wall of the main body of the container into the inner cavity of the container and has a spray head at the end of the extension. A solenoid valve is connected to the exhaust pipe. The water pump, solenoid valve, and electric ball valve are electrically connected to the network controller.
[0030] Furthermore, a float switch is installed in the main body of the container and is electrically connected to the network controller. When the spray control system is turned on, when the float switch reaches the preset float level, the network controller receives the float level signal and then shuts off the water pump, solenoid valve, and electric ball valve to stop the spraying. Through the above settings, quantitative spray disinfection can be achieved.
[0031] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
