Description

Technical Field

[0001] The utility model relates to biological waste processing equipment, more specifically, it relates to a waste tank for an isolator. Background Art

[0002] During the process of microbial culture, separation, identification and biological experiments, waste liquids containing microorganisms are inevitably generated. Such liquids may contain pathogenic microorganisms, genetically modified microorganisms or other biologically active microbial components, which are infectious or potentially harmful. If they are discarded at will, they may not only cause the microorganisms to spread into the environment, causing cross-infection or environmental pollution, but may also pose a threat to the health of operators and surrounding organisms. The current treatment method is mostly for operators to perform relevant operations on the operating platform. The waste liquid generated during the operation is transferred to a temporary container for temporary storage using tools such as pipettes and straws. However, during the operation, it is inevitable that some liquid will remain on the surface of the operating platform. As the operation continues, the residual waste liquid gradually accumulates. If the waste liquid cannot be cleaned up in time, it may not only be spilled due to the operator's accidental touch, but also leaked due to the liquid flowing to the edge of the operating platform, further increasing the risk of microbial spread. Utility Model Content

[0003] In view of the shortcomings of the existing technology, a waste tank for an isolator is provided, which can collect the waste liquid on the operating platform when the operator performs biological operations on the operating platform and generates waste liquid.

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom," "top," "inner," and "outer" refer to directions toward or away from the geometric center of a particular component, respectively.

[0025] Reference Figure 1-4 As shown, a waste tank for an isolator includes a shell assembly 1, a discharge device 2 installed on the shell assembly 1, a feeding device 3 installed on the shell assembly 1, a negative pressure driving device 4 for sucking air inside the shell assembly 1, and a connecting assembly 5;

[0026] The connecting assembly 5 is connected to the box for performing microbial operations and is detachably connected to the feeding device 3 through a pipeline for introducing waste liquid into the housing assembly 1;

[0027] The negative pressure driving device 4 is detachably connected to the housing assembly 1;

[0028] When microbial operations are performed in the box and waste liquid is generated, the negative pressure drive device 4 sucks the air inside the shell assembly 1, generating negative pressure suction on the channel formed between the connecting assembly 5 and the feeding device 3. The waste liquid flows into the shell assembly 1 through the connecting assembly 5 and the feeding device 3. The shell assembly 1 moves to a dischargeable location, and the waste liquid inside the shell assembly 1 is discharged through the discharge assembly.

[0029] The connecting component 5 and the feeding device 3 are detachably connected through a pipe (which can be an interference fit connection, or a threaded connection, etc.). The pipe can be a silicone hose or the like. As long as it can resist the erosion of the waste liquid and does not cause leakage, it can be used as a connection. When waste liquid is generated in the box, the negative pressure driving device 4 sucks the air inside the shell component 1 to form a negative pressure inside the shell component 1, so that the channel formed between the connecting component 5 and the feeding device 3 generates a negative pressure suction force. Under the action of negative pressure, the waste liquid continues to flow into the shell component 1 through the connecting component 5 and the feeding device 3; when discharge is required, the feeding device 3 and the negative pressure driving device 4 are removed, and the shell component 1 can be directly transferred to the discharge site, and the discharge device 2 is operated to discharge the waste liquid. This process actively attracts the waste liquid through negative pressure to collect it in real time, avoids the accumulation of residual liquid on the operating platform, and eliminates the risk of microbial leakage caused by excessive waste liquid.

[0030] Preferably, the connecting assembly 5 includes a chuck 51 , a first one-way valve 52 and a first connector 53 , and both ends of the first one-way valve 52 are respectively connected to the chuck 51 and the first connector 53 , forming a channel for the waste liquid to flow from the chuck 51 into the first connector 53 .

[0031] The chuck 51 is fixed at the liquid discharge port of the box body, and the first one-way valve 52 limits the one-way flow of liquid from the chuck 51 to the first connector 53; after the waste liquid enters through the chuck 51, the first one-way valve 52 blocks the backflow, ensuring that the liquid can only flow from the chuck 51 to the first connector 53 into the pipeline. The first one-way valve 52 can prevent the waste liquid from flowing back and contaminating the box body.

[0032] Preferably, the first connector 53 is provided with a plurality of blocking members 54 , which are sequentially connected into the pipeline to seal the connection between the pipeline and the first connector 53 .

[0033] The sealing member 54, such as a stepped sealing ring, enters the inner wall of the pipe along the axial direction of the pipe. If part of the waste liquid flows back to the connection between the pipe and the first connector 53, several sealing members 54 can step-by-step block the waste liquid. At the same time, the pipe connection is sealed and blocked by multiple layers of sealing members 54, ensuring that the negative pressure suction force is stably transmitted to the liquid discharge port of the box, avoiding a decrease in the liquid suction efficiency due to air leakage.

[0034] Preferably, the feeding device 3 includes a fixing part 31, a second one-way valve 32 and a second connector 33. The fixing part 31 is connected to the shell assembly 1, and the second connector 33 is connected to the first connector 53 through a pipeline. The two ends of the second one-way valve 32 are respectively connected to the fixing part 31 and the second connector 33, and a channel is formed for the waste liquid to flow into the shell assembly 1 through the second connector 33, the second one-way valve 32 and the fixing part 31.

[0035] After the waste liquid flows in from the second connector 33 through the pipeline, the second one-way valve 32 prevents the liquid or gas from leaking in the opposite direction, forcing the liquid to only pass through the second one-way valve 32 from the second connector 33 and enter the interior of the housing assembly 1 from the fixing part 31; the first one-way valve 52 and the second one-way valve 32 cooperate with each other to ensure the one-way flow of the waste liquid and maintain the air tightness of the system.

[0036] Preferably, the negative pressure drive device 4 includes a driver, a third connector 41 and a joint nut 42. The third connector 41 is connected to the shell assembly 1. The driver is connected to the third connector 41 through a pipe. The joint nut 42 is used to tighten the connection between the pipe and the third connector 41 so that the driver can suck the air inside the shell assembly 1.

[0037] When the driver (such as a vacuum pump, etc.) is running, one end of the pipe is connected to the driver, and the other end is connected to the third connector 41 through the joint nut 42. The driver continuously sucks the air inside the shell assembly 1. The joint nut 42 prevents the pipe from falling off by thread locking, forming a stable negative pressure environment to maintain the power to absorb waste liquid. At the same time, the detachable structure facilitates maintenance, replacement and disassembly during discharge.

[0038] Preferably, the shell assembly 1 includes a shell 11 with an opening at one end, a cover body 12 with an opening and a sealing cover 13 installed on the cover body 12. The cover body 12 is installed at the opening of the shell 11 and cooperates with the sealing cover 13 to seal the shell 11. The feeding device 3 and the third connector 41 are both installed on the sealing cover 13.

[0039] The cover body 12 can be tightly connected to the shell 11 by snaps or bolts, and the blind cover 13 can be connected to the cover body 12 by threads to achieve sealing; the fixing part 31 and the third connector 41 are both installed and integrated on the blind cover 13, which simplifies the pipeline layout and ensures that all interfaces are concentrated. At the same time, the blind cover 13 or the cover body 12 can be disassembled individually. The disassembly of the cover body 12 facilitates the overall disinfection of the shell 11, and the disassembly of the blind cover 13 facilitates the replacement of the feeding device 3 and the negative pressure drive device 4.

[0040] Preferably, the discharge device 2 includes an L-shaped water outlet pipe 21 and a handle 22 for controlling the water outlet pipe 21 , and the handle 22 is rotated to control the flow rate of the waste liquid.

[0041] The handle 22 rotates to drive the ball valve core in the L-shaped water outlet pipe 21 to adjust the on / off state or flow rate of the water outlet pipe 21; the L-shaped bending structure slows down the flow rate of the waste liquid when it is discharged to avoid liquid splashing.

[0042] Preferably, a sinking portion 111 is provided at the bottom of the shell 11 . The sinking portion 111 is provided with a through hole 112 connected to the water outlet pipe 21 . The sinking portion 111 is used to collect waste liquid to flow into the through hole 112 .

[0043] The funnel-shaped slope of the sinking portion 111 collects the waste liquid into the through hole 112 . The through hole 112 is connected to the water outlet pipe 21 , ensuring that the liquid inside the shell 11 flows to the water outlet pipe 21 through the through hole 112 .

[0044] Preferably, at least three universal wheels 14 are provided below the housing 11 , and the universal wheels 14 drive the housing 11 to move.

[0045] The universal wheels 14 are fixed to the bottom of the shell 11 through a wheel frame, so that the waste tank can be freely moved in the laboratory. When discharging, the waste tank can be pushed to the designated treatment area for discharge through the universal wheels 14, avoiding the risk of leakage caused by manual handling.
