Background Technology

[0002] Various waste liquids are frequently generated in laboratories. Improper handling of these waste liquids can not only pollute the environment but also pose a threat to the health of laboratory personnel. Traditional methods for handling waste liquids and solid wastes on laboratory benches are often rather crude and fail to achieve solid-liquid separation. Solid consumables such as pipette tips and filters are not effectively separated during experiments. Furthermore, ineffective measures to reduce evaporation during experiments allow harmful substances in the waste liquids to easily evaporate into the air, affecting laboratory air quality. In addition, traditional waste liquid containers are mostly fixed in one location, making them inconvenient to move. Therefore, it is necessary to develop a waste liquid container that can serve as a transport container during experiments. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a double-layer solid-liquid separation waste liquid box for laboratory desktop is provided. The waste liquid box mainly includes three parts: waste liquid box body 100, solid-liquid separation mechanism 200, and anti-volatile sealing cover 300. Its core solution is to detachably install the solid-liquid separation mechanism 200 inside the waste liquid box body 100 to form an upper and lower double-layer structure design. The lower layer is a liquid collection layer and the upper layer is a solid deposition layer. Solid-liquid separation can be achieved through the filter screen 202 at the bottom of the solid-liquid separation mechanism 200.

[0035] The top of the waste liquid box body 100 is provided with a flip-up anti-volatile sealing cover 300, and a sealing ring is provided at the connection between the cover and the anti-volatile sealing cover 300. To facilitate the installation of the solid-liquid separation mechanism 200, a limiting groove 101 is provided on the top of the left and right side plates of the waste liquid box body 100, and a limiting boss 102 is provided on the inner side wall in the middle along its circumference.

[0036] Matching the upper limit groove 101 and the limiting boss 102 of the waste liquid box body 100, the limiting ear plates 201 at the top left and right ends of the solid-liquid separation mechanism 200 and their bottoms are respectively embedded in the limiting groove 101 and the limiting boss 102, thereby stably installing the solid-liquid separation mechanism 200 in the middle position of the tank of the waste liquid box body 100.

[0037] The upper liquid collection layer and the lower solid deposition layer are separated by a filter screen 202 provided at the bottom of the solid-liquid separation mechanism 200. The filter screen 202 can be a filter cloth or a filter cover, etc., used to filter out the solid experimental consumables in the waste liquid, thereby achieving solid-liquid separation of the waste liquid.

[0038] In some of these embodiments, such as Figure 7 and Figure 8 As shown, in order to achieve the installation connection with the anti-volatile sealing cover 300, at least one set of first hinge blocks 103 is provided on the top of the back plate of the waste liquid box body 100, and the anti-volatile sealing cover 300 is hinged through the first hinge blocks 103.

[0039] As needed, a square sealing slot 104 is provided at the top center of the front plate of the waste liquid box body 100. The sealing slot 104 corresponds to the side cover plate 303 on the front side of the anti-volatile sealing cover 300. The height of the sealing slot 104 is greater than the height of the bottom filter screen 202 of the solid-liquid separation mechanism 200.

[0040] In some of these embodiments, such as Figure 7 and Figure 8 As shown, according to actual application needs, in order to facilitate the centralized collection of solid consumables separated from the solid-liquid separation mechanism 200, a consumables storage box 105 is provided on at least one side wall of the waste liquid box body 100. The bottom of the consumables storage box 105 is arranged at an angle to facilitate the placement of the collected consumables, allowing the waste liquid on the consumables to drain a second time under the action of gravity in a static manner.

[0041] As needed, a filter port 106 is provided on at least one side wall of the waste liquid container body 100, and the filter port 106 is correspondingly connected to the consumable storage box 105. The filter port 106 is a strip-shaped opening or consists of several arrayed through holes, and is located below the limiting boss 102. This allows the waste liquid from the secondary leaching of consumables stored in the consumable storage box 105 to be discharged into the bottom of the waste liquid container body 100 through the filter port 106.

[0042] In addition, such as Figure 3 , Figure 4 and Figure 6 As shown, brakeable wheels 107 are provided at the four corners of the bottom of the waste liquid box body 100. Rollers, pulleys or other moving devices can also be used to facilitate the experimenters to move the waste liquid box to the designated treatment location and improve the flexibility of use.

[0043] In some of these embodiments, such as Figure 9 and Figure 10 As shown, after use, in order to ensure the sealing between the waste liquid box body 100 and the anti-evaporation sealing cover 300, when installing the solid-liquid separation mechanism 200 in the waste liquid box body 100, the limiting ear plate 201 should be completely embedded in the limiting groove 101 and flush with the top of the waste liquid box body 100 to avoid the limiting ear plate 201 protruding and causing the evaporation and leakage of the waste liquid inside.

[0044] In some of these embodiments, such as Figure 5 and Figure 6 As shown, the rotatable configuration of the anti-volatile sealing cover 300 on the waste liquid box body 100 is installed in the following manner: a set of second hinge blocks 301 is provided on the rear end edge of the anti-volatile sealing cover 300, and the second hinge blocks 301 are hinged to the first hinge block 103 on the back plate of the waste liquid box body 100 via the central shaft 302.

[0045] By providing a sealable anti-evaporation cap 300 on the top of the waste liquid container body 100, the evaporation of harmful substances in the waste liquid into the air can be reduced to a certain extent. During use, the anti-evaporation cap 300 is flipped backward to fully expose the waste liquid container body 100 and its internal solid-liquid separation mechanism 200, facilitating the disposal of waste liquid containing solid consumables. After use, the anti-evaporation cap 300 is manually sealed on top of the waste liquid container body 100 to reduce the evaporation of the lower layer of waste liquid.

[0046] Furthermore, corresponding to the sealing groove 104 on the front panel of the waste liquid container body 100, a downwardly arranged side cover plate 303 is provided at the center of the front end edge of the anti-volatile sealing cover 300. The side cover plate 303 is correspondingly embedded in the sealing groove 104 of the waste liquid container body 100. If necessary, a handle can be installed on the side cover plate 303 for easy manual flipping of the anti-volatile sealing cover 300.

[0047] In some embodiments, the waste liquid container body 100, the solid-liquid separation mechanism 200, and the anti-volatile sealing cap 300 are all made of wear-resistant, corrosion-resistant, acid- and alkali-resistant PP polypropylene material. Acid- and alkali-resistant PP polypropylene material can withstand the corrosion of various strong acids and alkalis and has good chemical stability. This characteristic makes it particularly important in industries such as chemical engineering and environmental protection that require the handling of corrosive substances. Furthermore, acid- and alkali-resistant PP polypropylene material itself also has good heat resistance, good physical and mechanical properties, is non-toxic and odorless, and has good processability.

[0048] This invention designs the waste liquid box as a double-layer structure consisting of a waste liquid box body 100 and a solid-liquid separation mechanism 200. The lower layer is a liquid collection layer, and the upper layer is a solid deposition layer. The solid-liquid separation mechanism 200 can effectively filter out solid experimental consumables from the waste liquid. Furthermore, the anti-volatile sealing cover 300 that can be flipped on the top and the brakeable wheels 107 at the bottom can effectively reduce the volatilization of waste liquid and make it easy for experimental personnel to move the waste liquid box to the designated treatment location, making it flexible and convenient to use.

[0049] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
