[0034] In this embodiment, as Figure 1 and Figure 2 shown, a laboratory sink facilitating water drainage includes a sink body 1. A water drainage assembly 2 is arranged on the sink body 1. The water drainage assembly 2 is used for collecting solid impurities in the liquid. The water drainage assembly 2 includes a placement plate 21, a blanking shell 22, two filter cylinders 23, a filter screen 24, and a connecting piece 25. The placement plate 21 is inserted into the strip-shaped groove of the sink body 1. The blanking shell 22 is fixedly connected to the bottom of the placement plate 21. The two filter cylinders 23 are respectively embedded into the top card slots of the placement plate 21. Through the arrangement of the two filter cylinders 23, not only can impurities in the liquid be collected, but they can also be used alternately. The filter screen 24 is installed at the bottom of the blanking shell 22. The filter screen 24 is connected to the blanking shell 22 through the connecting piece 25. Through the arrangement of the filter screen 24, the liquid is filtered twice.

[0035] Thus, the filter cartridge 23 is inserted into the card slot at the top of the placement board 21. When using the water tank body 1, the liquid containing impurities is first poured into the filter cartridge 23. After the filter cartridge 23 filters the liquid for the first time, the liquid passes through the filter screen 24 along the material discharge shell 22 for secondary filtration, and then the liquid enters the water tank body 1. The impurities in the liquid are filtered by the filter cartridge 23 and the filter screen 24 to prevent the impurities from blocking the water tank body 1 and adhering to the inner wall of the water tank body 1. At the same time, the two filter cartridges 23 are used alternately. When one filter cartridge 23 is cleaned, the other filter cartridge 23 continues the filtration work without affecting the filtration efficiency of the liquid.

[0036] Furthermore, two filter cartridges 23 are provided for alternate use. The placement board 21 can close the water tank body 1 or be used to place liquid containers. The connecting piece 25 is a bolt. The filter holes of the filter screen 24 are smaller than the filter holes on the filter cartridge 23. After the filter screen 24 is removed, the material discharge shell 22 can be cleaned.

[0037] In some embodiments, as Figure 3 and Figure 4 shown, a driving component 3 is installed in the water tank body 1. The driving component 3 is used to adjust the position of the placement board 21 in the water tank body 1. The driving component 3 includes a transmission shaft 31, a sliding seat 32, a fixing piece 33, an auxiliary piece 34 and a turning knob 35. The transmission shaft 31 is rotatably connected to the water tank body 1 through a bearing. The sliding seat 32 is threadedly connected to the transmission shaft 31. The sliding seat 32 is connected to the placement board 21 through the fixing piece 33. When the transmission shaft 31 rotates, the placement board 21 is driven to move horizontally by the sliding seat 32. The auxiliary piece 34 is used to assist the horizontal movement of the sliding seat 32. The turning knob 35 is fixedly connected to one end of the transmission shaft 31 passing through the water tank body 1.

[0038] Furthermore, the outer wall of the transmission shaft 31 is processed with threads. The sliding seat 32 drives the placement board 21 to move through the fixing piece 33. A groove adapted to the ear plate 331 is processed at the top of the sliding seat 32. The outer wall of the turning knob 35 is processed with abrasive patterns to increase the friction with the hand. The use of the auxiliary piece 34 makes the movement of the sliding seat 32 smoother.

[0039] In some embodiments, as Figure 3 shown, the fixing piece 33 includes an ear plate 331 and a bolt 332. The ear plate 331 is inserted into the groove of the sliding seat 32. One end of the ear plate 331 away from the sliding seat 32 is fixedly connected to the placement board 21. The ear plate 331 is connected to the sliding seat 32 through the bolt 332.

[0040] Furthermore, two ear plates 331 are provided. The bolt 332 connects the ear plate 331 and the sliding seat 32. When the sliding seat 32 drives the placement board 21 to completely fit with the top edge of the water tank body 1, the tail end of the placement board 21 is separated from the strip-shaped groove of the water tank body 1. At this time, the bolt 332 is removed to disassemble and wash the placement board 21.

[0041] In some embodiments, as Figure 5 shown, the auxiliary member 34 includes a support plate 341 and a roller 342. The top end of the support plate 341 is fixedly connected to the sliding seat 32, and the roller 342 is hinged to the support plate 341 through a pin shaft.

[0042] Furthermore, there are two support plates 341. The roller 342 rotates between the two support plates 341. The use of the roller 342 makes the movement of the sliding seat 32 smoother.

[0043] In some embodiments, as Figure 5 shown, a limiting plate 11 is fixedly connected in the water tank body 1, and a limiting groove adapted to the roller 342 is machined inside the limiting plate 11.

[0044] Furthermore, the limiting groove in the limiting plate 11 is used to restrict the traveling direction of the roller 342.

[0045] In some embodiments, as Figure 4 shown, a drainage member 12 is arranged on the water tank body 1. The drainage member 12 is used to drain the accumulated water in the water tank body 1. The drainage member 12 includes a convex panel 121 and a drain pipe 122. The convex panel 121 is fixedly connected to the bottom of the water tank body 1, and the top end of the drain pipe 122 is fixedly connected to the convex panel 121.

[0046] Furthermore, a groove is machined in the convex panel 121 for collecting liquid and guiding it into the drain pipe 122. The drain pipe 122 is a telescopic flexible hose.

[0047] In some embodiments, as Figure 2 shown, a cavity with a wider top and a narrower bottom is machined in the blanking shell 22.

[0048] Furthermore, the design of the blanking shell 22 with a cavity having a wider top and a narrower bottom facilitates the collection of liquid at the bottom of the blanking shell 22 for discharging into the water tank body 1.

[0049] In some embodiments, as Figure 2 shown, the placement plate 21 is in a flat plate shape and is used for placing experimental containers.

[0050] Furthermore, the placement plate 21 is used to place laboratory containers filled with liquid or laboratory containers that have been cleaned.

[0051] The working principle of the present application will be described below with a preferred embodiment:

[0052] First, install the sink body 1 in the test bench. Pour the experimental waste liquid containing impurities into the filter cartridge 23. After the filter cartridge 23 filters the liquid for the first time, the liquid enters the blanking shell 22. After passing through the filter screen 24 for secondary filtration, the liquid enters the convex panel 121 at the bottom of the sink body 1 and is discharged through the drain pipe 122. By directly pulling the filter cartridge 23 to separate from the placement plate 21, the impurities in the filter cartridge 23 can be cleaned. The setting of two filter cartridges 23 allows for replacement and use without affecting the liquid filtration efficiency. When it is necessary to clean the impurities remaining in the blanking shell 22, rotate the connecting piece 25 to separate from the filter screen 24, and then remove the filter screen 24 from the bottom of the blanking shell 22 to clean the cavity of the blanking shell 22. When the sink body 1 is not in use, drive the transmission shaft 31 to rotate in the sink body 1 through the rotary knob 35. Then, the sliding seat 32 drives the placement plate 21 to move horizontally along the internal strip-shaped groove of the sink body 1 through the ear plate 331. The rollers 342 located at the bottom of the sliding seat 32 move along the chute of the limiting plate 11 to increase the smoothness of the sliding seat 32 during movement. The top of the sink body 1 is closed by the placement plate 21.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
