Abstract
Description
Technical Field
[0001] This utility model relates to the field of laboratory waste liquid treatment technology, and in particular to a leak-proof laboratory waste liquid collection device. Background Technology
[0002] In fields such as testing and inspection, and laboratory analysis, various types of testing waste liquids (such as chemical reagent waste liquids and sample rinsing waste liquids) are generated daily. If these waste liquids are not collected properly, they are prone to dripping and splashing, which can not only corrode laboratory surfaces and floors, but also cause environmental pollution and even pose safety risks to personnel. Currently, most devices lack targeted leak-proof structures, and waste liquids can easily splash from the edges of containers during pouring or transfer. Moreover, some devices do not have spare leak-proof components, so once the main storage container leaks, it cannot be intercepted in time. Furthermore, most devices are fixed structures and cannot be flexibly moved to different experimental areas. For small-diameter drainage pipes of small experimental equipment, there is a lack of dedicated fixing and liquid guiding structures, which can easily lead to pipe misalignment and waste liquid dripping during drainage.
[0003] Therefore, there is an urgent need to design a leak-proof waste liquid collection device to solve the above-mentioned technical problems. Summary of the Invention
[0004] In order to overcome the shortcomings of the prior art, the present invention provides a drip-proof test waste liquid collection device.
[0005] Technical Solution: A leak-proof test waste liquid collection device includes a movable base frame, a collection frame, an outlet pipe, a support frame, a collection tray, a placement component, a collection bucket, an exhaust pipe, an inlet pipe, a valve, an inlet component, and a gas filter. The collection frame is located on the top of the movable base frame, with an outlet pipe connected to the bottom of the collection frame. A ball valve is installed on the outlet pipe. A support frame is located on the top right side of the movable base frame, with a collection tray on the upper left side of the support frame. A guide hole is opened on the bottom right side of the collection tray, and the guide hole is located above the right side of the collection frame. A placement component for fixing the collection bucket is placed on the collection frame. An exhaust pipe is connected to the top of the collection bucket, and a gas filter is installed on the exhaust pipe. An inlet pipe is connected to the center of the top of the collection bucket, and a valve is installed on the inlet pipe. An inlet component that cooperates with the collection bucket is installed on the collection tray.
[0006] Optionally, the placement assembly includes a rectangular ring frame, a first hydrophobic plate, and a placement frame. The inner sidewall of the collection frame is provided with a rectangular ring frame, the first hydrophobic plate is placed on the rectangular ring frame, and the placement frame for placing the liquid collection tank is provided in the middle of the first hydrophobic plate.
[0007] Optionally, the liquid inlet assembly includes a threaded tube, a hose, a funnel, and a second hydrophobic plate. The threaded tube is detachably installed at the center of the liquid collection tray. The lower end of the threaded tube is connected to a hose, and the lower end of the hose is connected to the liquid inlet tube. The upper part of the threaded tube is screwed with a funnel, and the second hydrophobic plate is installed inside the funnel.
[0008] Optionally, it also includes retaining rings, with retaining rings spaced apart on the inner sidewall of the funnel.
[0009] Optionally, it also includes an elastic retaining sleeve, with an elastic retaining sleeve provided on the upper part of the placement frame.
[0010] Optionally, it also includes a card plate and a collection bucket. Card plates are symmetrically arranged on the left side wall of the placement frame. A circular hole is opened in the center of the card plate, and the card plate is used to limit the position of the collection bucket.
[0011] Compared with the prior art, the present invention has the following advantages: 1. This device, through a multi-layered anti-drip and secondary interception structure, precisely solves the core problems of existing devices, such as easy splashing and dripping during waste liquid pouring and transfer, and lack of interception for main container leakage. The second hydrophobic plate of the liquid inlet assembly disperses the impact force of the waste liquid and guides its directional flow, preventing the waste liquid from splashing along the container edge or dripping along the outer wall; the collection tray and collection frame form double protection, so even if the waste liquid is spilled out misaligned, it can be quickly collected and further buffered and dispersed by the guide holes and the first hydrophobic plate, completely eliminating dripping and splashing. It effectively prevents the waste liquid from corroding the experimental platform and ground, and also blocks the environmental pollution path at the source, significantly reducing the safety risks of personnel directly contacting the waste liquid.
[0012] 2. This device overcomes the pain points of existing devices, such as inconvenient fixation and lack of a fixed liquid guiding structure for small-diameter drainage pipes, thanks to its flexible mobility and specialized adaptable structure. The mobile base can flexibly move between different experimental areas, breaking the limitations of fixed devices and adapting to the waste liquid collection needs of various scenarios; the fixing ring on the inside of the funnel can stably fix the small-diameter drainage pipe, and together with the limiting effect of the elastic fixing sleeve and the placement frame, it effectively avoids leakage caused by pipe misalignment during drainage.

Detailed Implementation

The collection frame 2 is mounted on the top of the movable base frame 1, and the outlet pipe 3 is connected to the bottom of the collection frame 2. A ball valve is mounted on the outlet pipe 3. The support frame 4 is mounted on the top right side of the movable base frame 1, and the collection tray 5 is mounted on the upper left side of the support frame 4. A guide hole 6 is opened on the bottom right side of the collection tray 5. A placement component 7 for fixing the collection bucket 8 is placed on the collection frame 2. The placement component 7 includes a rectangular ring frame 71 and a first hydrophobic plate. 72 and a placement frame 73, a rectangular ring frame 71 is provided on the inner side wall of the collection frame 2, a first hydrophobic plate 72 is placed on the rectangular ring frame 71, a placement frame 73 for placing the collection tank 8 is provided in the middle of the first hydrophobic plate 72, the top of the collection tank 8 is connected to an exhaust pipe 9, a gas filter 13 is installed on the exhaust pipe 9, the top center of the collection tank 8 is connected to an inlet pipe 91, a valve 92 is provided on the inlet pipe 91, the collection tray 5 is installed with an inlet assembly 10 that cooperates with the collection tank 8, the inlet assembly 10 includes a threaded pipe 101, a hose 102, a funnel 103 and a second hydrophobic plate 11, the threaded pipe 101 is detachably installed at the center of the collection tray 5, the lower end of the threaded pipe 101 A flexible hose 102, made of food-grade PV material, is connected to the inlet pipe 91 via a threaded connector (G1 / 2 specification) at its lower end. A nitrile rubber sealing ring (2mm cross-sectional diameter) is fitted at the connector to ensure a leak-proof seal. A funnel 103 is screwed onto the upper part of the threaded hose 101. A second hydrophobic plate 11 is installed inside the funnel 103. The system also includes a fixing ring 12, an elastic fixing sleeve 14, a retaining plate 15, and a collection bucket 16. Fixing rings 12 are spaced apart on the inner wall of the funnel 103. An elastic fixing sleeve 14, made of medical-grade silicone material (Shore hardness 40-50), is installed on the upper part of the placement frame 73. HA (elongation ≥300%), inner diameter adapted to the outer diameter of collection tank 8 (adaptation range 15-20cm), the collection tank is fixed by interference fit to prevent displacement, and a clamping plate 15 is symmetrically arranged on the left side wall of the placement frame 73. The clamping plate 15 has a round hole in the center and is used to limit the collection tank 16. The first hydrophobic plate 72 and the second hydrophobic plate 11 are both made of polytetrafluoroethylene and coated with a nano-silica hydrophobic coating (coating thickness 5-8μm, water contact angle ≥120°). Circular through holes are evenly opened on the plate body. The hole diameter is 2-3mm and the hole spacing is 5mm. They are arranged in an equilateral triangle to disperse the impact force of waste liquid and guide directional flow.
[0021] After the test is completed, waste liquid is collected. Depending on the amount of waste liquid generated, either collection tank 8 or collection bucket 16 is selected. When a large amount of waste liquid is generated in a large-scale experiment, the hose 102 is connected to the inlet pipe 91 of collection tank 8 through a threaded joint with a nitrile rubber sealing ring. The valve 92 is opened, and the waste liquid is injected through funnel 103. The second hydrophobic plate 11 isolates the waste liquid. The perforated second hydrophobic plate 11 first catches the falling waste liquid and disperses the impact force to avoid splashing. The edge of the plate is tightly attached to the wall of funnel 103 to form a sealed channel, guiding the waste liquid to flow downward along the plate surface and preventing dripping along the outer wall of funnel 103. The waste liquid enters the collection tank 8 through the hose 102. As the waste liquid rises, the gas in the collection tank 8 is discharged through the exhaust pipe 9. The gas filter 13 filters the discharged gas before it is discharged. When the waste liquid is poured into funnel 103 and spills out in a staggered manner, it first flows into the collection tray 5, then drips through the guide hole onto the first hydrophobic plate 72, further dispersing the impact force to prevent splashing, and finally flows into the collection frame 2. To dispose of the waste liquid in collection frame 2, simply open the ball valve, and the waste liquid in collection frame 2 will flow out through the outlet pipe 3 for collection. When a large amount of waste liquid is generated in a small experiment, the drain pipe can be clamped onto the fixing ring 12, and the flexible tube 102 can be inserted into the collection bucket 16 for collection. This device has a simple structure and is easy to operate.
