[0044] The following is a description with reference to the accompanying drawings and a specific embodiment.

[0045] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention.

[0046] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in the subsequent drawings.

[0047] See also Figures 1 to 3 The clean bench-specific experimental waste liquid collection device described in this embodiment includes a classification delivery pipe 200 and a waste collection box. Obviously, the waste collection box is provided with a box door or a box cover so that the waste can be taken out or poured out. The first end of the classification delivery pipe 200 is connected to a waste classification tray 100, and the second end of the classification delivery pipe 200 is connected to a waste bin. When in use, the waste classification tray 100 is placed in the clean bench, and the waste bin is placed on the ground.

[0048] See also Figure 1 In this embodiment, the garbage classification plate 100 is a hollow platform, and a liquid classification port 101 is arranged on the upper surface of the hollow platform. The liquid classification port 101 is connected to the third conveying pipe 230 through the third pipe port 231, and the third conveying pipe 230 is detachably connected to the third garbage bin 320. In order to facilitate the solid-liquid separation of experimental garbage, a screen (not shown in the drawings) is installed on the liquid classification port 101, and solid garbage (including dry garbage and solid hazardous garbage) is retained on the screen, and liquid garbage flows down from the screen and enters the third conveying pipe 230 from the third pipe port 231. In order to prevent the garbage on the garbage classification plate 100 from falling onto the clean bench, a baffle 102 is arranged at the edge of the garbage classification plate 100. The baffle 102 is arranged at the edge of the garbage classification plate 100, which also facilitates the delivery of dry garbage and solid hazardous garbage into the corresponding conveying pipe. In this embodiment, the front section of the third conveying pipe 230 is a rectangular tube or a flat tube, which is convenient for placing and fixing the classification conveying pipe 200. After the third conveying pipe 230 is separated from the combined pipe section, it gradually transitions to a circular tube and is finally connected to the third garbage bin 320.

[0049] See also Figure 3In this embodiment, the classification delivery pipe 200 includes a first delivery pipe 210, a second delivery pipe 220 and a third delivery pipe 230. The classification delivery pipe 200 is a hose, which is convenient for adjusting the position and angle of the garbage classification plate 100; of course, the classification delivery pipe 200 can also be set as a hard pipe, and the garbage classification plate 100 is set horizontally or at an elevation to ensure that the waste liquid does not overflow onto the clean bench. The first delivery pipe 210 and the second delivery pipe 220 are connected to a negative pressure trash bin 310, which is a trash bin connected to a vacuum pump, that is, dry garbage and solid hazardous garbage are sucked into the corresponding space by negative pressure suction, and negative pressure is formed at the first pipe mouth 211 and the second pipe mouth 221 to ensure the clean air in the clean bench. The negative pressure trash bin 310 is provided with a vacuum pump connection hole 311. When in use, the vacuum pump connection hole 311 is connected to a vacuum pump (not shown in the figure), and the switch of the vacuum pump can be set below the clean bench, which is convenient for the experimental operator to control the vacuum pump switch with his feet.

[0050] See also Figure 2 In this embodiment, a middle partition 312 is provided in the negative pressure trash bin 310, and the middle partition 312 divides the internal space of the negative pressure trash bin 310 into a first trash bin and a second trash bin. The first conveying pipe 210 is connected to the first trash bin, and the second conveying pipe 220 is connected to the second trash bin. The vacuum pump connection hole 311 is provided above the middle partition 312. This arrangement enables the vacuum pump connection hole 311 to simultaneously connect the first trash bin and the second trash bin, making it convenient to use the same vacuum pump to simultaneously pump the first trash bin and the second trash bin into negative pressure. It should be noted that as long as the first trash bin and the second trash bin are connected, the vacuum pump connection hole can be set at any position on the top of the trash bin. Moreover, the first trash bin and the second trash bin can even be connected through a pipeline.

[0051] As an alternative but not recommended solution, the first trash bin and the second trash bin are two independent trash bins, each of which is connected to a vacuum pump; or, the first trash bin and the second trash bin are two independent trash bins, and the two trash bins are connected to the same vacuum pump via a three-way valve.

[0052] The front section of the classification delivery pipe 200 is a combined pipe section of the first delivery pipe 210, the second delivery pipe 220 and the third delivery pipe 230. The rear section of the classification delivery pipe 200 is a separated pipe section of the first delivery pipe 210, the second delivery pipe 220 and the third delivery pipe 230. The combined pipe section is provided to facilitate the setting of the garbage classification plate 100, thereby facilitating the experimental garbage classification, and at the same time, it can also keep the clean bench surface clean and tidy without affecting the experimental operation. The first delivery pipe 210 is provided with a first pipe opening 211, and the second delivery pipe 220 is provided with a second pipe opening 221. The first pipe opening 211 and the second pipe opening 221 are arranged side by side, and valves 201 are installed on the first pipe opening 211 and the second pipe opening 221. The first pipe opening 211 and the second pipe opening 221 are 1 / 4 fan-shaped pipe openings of equal size, and the first pipe opening 211 and the second pipe opening 221 constitute a semicircular pipe opening.

[0053] In this embodiment, in the combined pipe section, the first conveying pipe 210 is a 1 / 4 sector-shaped pipe, and the second conveying pipe 220 is a 1 / 4 sector-shaped pipe that is equal in size to the first conveying pipe 210 and is symmetrically arranged in a plane. The first conveying pipe 210 and the second conveying pipe 220 share the same partition, which divides a semicircular pipe into two equal-sized 1 / 4 sector-shaped pipes.

[0054] See also Figure 1 In this embodiment, only one valve 201 is provided, and the valve is provided on the first pipe opening 211 and the second pipe opening 221. The valve 201 is a 1 / 4 sector plate, and a rotating shaft connection assembly is provided between the fixed point of the sector plate and the center of the semicircular pipe opening. The valve 201 is provided with a toggle rod 2011, and the rotation of the valve 201 is controlled by the toggle rod 2011. The valve 201 can only close and open one of the first pipe opening 211 and the second pipe opening 221 at the same time. When the first pipe opening 211 is in a closed state, the second pipe opening 221 is in an open state; when the first pipe opening 211 is in an open state, the second pipe opening 221 is in a closed state.

[0055] During the experimental operation, after the garbage is generated, the liquid garbage can be directly poured into the liquid classification port 101 and flow into the third garbage bin through the third conveying pipe 230. After the dry garbage or solid hazardous garbage is generated, the operator turns on the vacuum pump with his foot, and the first garbage bin and the second garbage bin are both pumped to negative pressure. The first pipe port 211 is opened, the second pipe port 221 is closed, and the dry garbage is placed at the first pipe port 211. Under the action of negative pressure suction, the dry garbage is collected into the first garbage bin through the first conveying pipe 210; or the first pipe port 211 is closed, the second pipe port 221 is opened, and the solid hazardous garbage is placed at the second pipe port 221. Under the action of negative pressure suction, the solid hazardous garbage is collected into the second garbage bin through the second conveying pipe 220. After completing the garbage collection, the operator can turn off the vacuum pump switch with his foot.
