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 connected in a straight line. 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. Summary of the Invention

[0009] To address or partially address the problems existing in related technologies, this application provides a disinfection collection tank for use in the straight-line connection of live toxic wastewater drainage pipes. In this application, the upper and lower tanks are detachably connected by several sets of snap-fit ​​structures located at their mating edges. Grooves are provided around the opening ends of both the upper and lower tanks for filling with sealant. This design allows for quick assembly of the disinfection collection tank at the straight-line connection of the live toxic wastewater drainage pipes. When leakage occurs at the weld of the live toxic wastewater drainage pipe, the disinfection collection tank serves as a space for spray disinfection and to collect the disinfected wastewater. After disinfecting the leaked liquid inside the collection tank, the disinfected wastewater is discharged, and the collection tank can be quickly opened to repair the leak. Once repaired, the disinfection collection tank can be quickly reinstalled on the live toxic wastewater drainage pipe.

[0010] This application discloses a disinfection collection tank for use with live-virus wastewater drainage pipes connected in a straight line. It includes a hollow, hexahedral main body with an internal cavity. The main body is formed by an upper and lower body joined together along a horizontal parting line, with grooves on the open ends of both the upper and lower bodies for filling with sealant. Several sets of fastening structures are provided along both sides of the parting line of the upper and lower bodies to secure them. A columnar horizontal through-hole extends through two opposite sides of the upper and lower bodies for the live-virus wastewater drainage pipe to pass through. When the main body is installed on the live-virus wastewater drainage pipe, the through-hole formed between the horizontal through-hole and the two opposite sides of the main body for the live-virus wastewater drainage pipe is an interference fit.

[0011] Furthermore, positioning posts are fixed at each of the four corners of the upper or lower housing.

[0012] Furthermore, the bottom of the lower box is provided with a drain hole, the upper box is provided with a spray disinfection and exhaust hole, and a spray hole is provided on either the upper or lower box. The top of the upper box is provided with a leakage monitoring cable through hole. Connectors are provided for the drain hole, disinfection and exhaust hole, and spray hole respectively. Cable connectors are provided for the leakage monitoring cable through hole. A drain pipe with a valve is connected to the connector corresponding to the drain hole; The water tank connector corresponding to the disinfection vent is connected to an exhaust pipe, 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 water tank connector corresponding to the spray hole. The end of the spray pipe facing the inner side of the tank body is connected to a spray head, and the end of the spray pipe facing the outer side of the tank body is connected to the disinfectant storage tank. A solenoid valve, a water pump, and a pre-filter are sequentially installed on the spray pipe.

[0013] Furthermore, the fastening structure is an adjustable hook and loop fastener.

[0014] Furthermore, the main body of the box is made of acrylic material.

[0015] Furthermore, the main body of the box is provided with a gas disinfection inlet and a gas disinfection outlet, and each of the gas disinfection inlet and the gas disinfection outlet is provided with a connector.

[0016] Furthermore, a float switch is provided throughout the upper housing.

[0017] Furthermore, the horizontal parting surface passes through the centerline of the horizontal through channel.

[0018] The beneficial effects of this application are: 1. The disinfection collection tank in this application has a main body consisting of an upper tank and a lower tank that are joined together along a horizontal parting surface. Several sets of fastening structures are provided along the parting surface of the upper and lower tanks. A columnar horizontal through-channel is provided through two opposite sides of the main body of the tank for the passage of a live toxic wastewater drain pipe. When the main body of the tank is installed on the live toxic wastewater drain pipe, the through hole formed between the horizontal through-channel and the two opposite sides of the main body for the live toxic wastewater drain pipe is an interference fit with the live toxic wastewater drain pipe.

[0019] By adopting the above design, on the one hand, the disinfection collection tank can be quickly installed at the point where the live toxic sewage drain pipe is connected in a straight line; on the other hand, when leakage occurs at the weld of the live toxic sewage drain pipe, the disinfection collection tank can be used as a space to provide spray disinfection and collect the disinfected wastewater. After the leaking liquid is disinfected inside the disinfection collection tank, the disinfected wastewater can be discharged, and the disinfection collection tank can be quickly opened to repair the leak. After the repair is completed, the disinfection collection tank can be quickly reinstalled on the live toxic sewage drain pipe.

[0020] Specifically, grooves are provided around the opening ends of both the upper and lower housings for filling with sealant; this design ensures good sealing performance between the upper and lower housings and the toxic wastewater drain pipe.

[0021] 2. The main body of the box in this application is formed by the upper box and the lower box being joined together along a horizontal parting surface. It is suitable for situations where the live toxic sewage drain pipes are connected in a straight line. Because of the weld at the connection of the two pipes, the probability of leakage is extremely high. When using it, the main body of the box can be assembled at the place where the live toxic sewage drain pipes are connected in a straight line.

[0022] 3. The main body of the container in this application is used to provide space for spray disinfection. Specifically, in case of leakage from the live toxic wastewater drain pipe in the main body of the container, disinfection can be carried out by spraying disinfectant liquid or blowing in disinfectant gas.

[0026] The embodiments of this application will now be described in more detail with reference to the examples. 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. Example

[0027] like Figure 1 As shown, a disinfection collection tank for use in a straight-line connection of live toxic wastewater drainage pipes includes a hollow hexahedral main body 100 with an internal cavity. The main body is formed by an upper body 1 and a lower body 2 joined together along a horizontal parting surface. Grooves 4 are provided around the opening faces of both the upper and lower bodies for filling with sealant. Here, the "parting surface" refers to the imaginary plane that contacts the two parts when the main body is divided, and "horizontal" indicates that this parting surface is horizontal. In other words, the main body is essentially cut by a horizontal plane.

[0028] Furthermore, such as Figure 2 and Figure 3 As shown, the groove 4 is formed along the opening end faces of the upper and lower boxes. In this embodiment, the groove is 3mm wide and 3mm deep. The groove 4 is used to fill sealant during the assembly of the box body 100. After the upper box 1 and lower box 2 are opened and closed, the previously filled sealant can be removed, and then the sealant can be refilled when the upper box 1 and lower box 2 are reassembled. The groove 4, together with the sealant, can prevent the leakage of toxic wastewater inside the box body 100.

[0029] Several sets of fastening structures 3 are provided on both sides of the parting surface of the upper box 1 and the lower box 2 to secure them together. The fastening structures 3 serve to secure the upper box 1 and the lower box 2, preventing them from separating due to gravity caused by the entry of disinfectant into the main body 100 of the box. Furthermore, the fastening structures 3 facilitate quick assembly. Specifically, the fastening structure 3 is an adjustable snap fastener.

[0030] Simultaneously, a columnar horizontal through-channel 200 is provided through the two opposite sides of the upper box 1 and the lower box 2 for the passage of the live toxic sewage drain pipe; when the box body 100 is installed on the live toxic sewage drain pipe, the through hole formed between the horizontal through-channel 200 and the two opposite sides of the box body 100 for the live toxic sewage drain pipe to pass through is an interference fit with the live toxic sewage drain pipe.

[0031] Furthermore, such as Figure 4 As shown, after the live toxic wastewater drain pipe 300 is installed on the main body 100 of the tank, the contact point between the live toxic wastewater drain pipe 300 and the main body 100 of the tank can be further sealed by applying solid sealant. In this way, when disinfectant is sprayed into the main body 100 of the tank to disinfect the leaked liquid, the leakage of disinfected wastewater can be prevented.

[0032] Furthermore, positioning posts 5 are fixed at each of the four corners of the upper or lower housing. The positioning posts 5 facilitate the quick positioning and connection of the upper housing 1 and the lower housing 2.

[0033] Furthermore, in order for the live toxic sewage drain pipe to fall more effectively into the horizontal through channel on the lower housing 2, the horizontal parting surface passes through the center line of the horizontal through channel 200.

[0034] Furthermore, for ease of observation and low-cost assembly, the main body 100 of the box is made of acrylic material.

[0035] Furthermore, the bottom of the lower housing 2 is provided with a drain hole, the upper housing 1 is provided with a spray disinfection and exhaust hole, a spray hole is provided on the upper housing 1, and the top of the upper housing 1 is provided with a leakage monitoring cable through hole; a connector 6 is provided corresponding to the drain hole, disinfection and exhaust hole, and spray hole; a cable connector is provided corresponding to the leakage monitoring cable through hole. 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 disinfection exhaust hole, 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.

[0036] 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.

[0037] 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.

[0038] Furthermore, a float switch 7 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 7 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.

[0039] 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.
