[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0035] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0036] In some embodiments, Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, an integrated experimental table multi-joint waste liquid collection device is provided, which mainly includes an experimental table 100, a straight drain pipe 300, a locking nut 400, a waste liquid collection bucket 600, a safety bottle cap 700 and at least one waste liquid collection pipe 900. The straight drain pipe 300 and the locking nut 400 are fixedly installed on the experimental table 100, the waste liquid collection bucket 600 is installed in the cabinet below the experimental table 100, and the safety bottle cap 700 is installed on the top of the straight drain pipe 300.

[0037] Specifically, the straight drain pipe 300 is inserted into the mounting hole 101 from above the experimental table 100, and the locking nut 400 is threadedly installed on the upper end of the straight drain pipe 300. By tightening the locking nut 400, the straight drain pipe 300 can be fixedly installed in the mounting hole 101 of the experimental table 100. The lower end of the straight drain pipe 300 is connected to the waste liquid collection bucket 600, and the top end is threadedly connected to the safety bottle cap 700; and at least one waste liquid collection pipe 900 is arranged on the top of the safety bottle cap 700, and each waste liquid collection pipe 900 is connected to the waste liquid collection funnel at different stations of the experimental table 100 through a pipeline. The installation position of the waste liquid collection funnel has a certain height, which can make the waste liquid flow to the waste liquid collection pipe 900 along the pipeline.

[0038] In some of the embodiments, Figure 2 , Figure 4 , Figure 6 , Figure 8 and Fig. 9As shown, the upper end of the straight discharge pipe 300 is fixedly mounted in the mounting hole 101 through a diffuser sleeve 200 sleeved thereon. The diffuser sleeve 200 adopts a T-shaped hollow sleeve structure design, and is mainly composed of an annular pressing sheet 201 at the upper end and a plurality of diffuser plates 202.

[0039] Specifically, a plurality of the diffuser plates 202 are arranged at annular intervals at the bottom of the annular pressing plate 201 , and an inlet groove 203 extending upward to the inner wall of the annular pressing plate 201 is formed between two adjacent diffuser plates 202 for inserting the straight drainage pipe 300 from above the diffuser sleeve 200 .

[0040] In order to quickly move the straight drain pipe 300 upward and lock it in the diffuser sleeve 200, and to prevent the straight drain pipe 300 from synchronously rotating when the locking nut 400 is tightened, a clamping groove 204 is provided at the bottom of the diffuser plate 202 near the inlet groove 203 on the same side. The plate body corner inside the top of the clamping groove 204 is arranged as an arc surface or an inclined surface, and the arc surface or the inclined surface is arranged in coordination with the top inclined surface of the inclined pressure block 303.

[0041] When in use, the inclined pressure block 303 at the lower end of the drainage straight pipe 300 is rotated from the lower end of the inlet groove 203 to the corresponding card groove 204, one hand presses the diffuser sleeve 200 to keep it still, and the other hand rotates the locking nut 400. The locking nut 400 simultaneously drives the drainage straight pipe 300 to move upward during rotation, so that the diffuser plates 202 around the diffuser sleeve 200 are squeezed outward through the inclined pressure block 303 and pressed tightly against the mounting hole 101, so that the diffuser sleeve 200 is firmly fixed on the experimental bench 100, and at the same time, the drainage straight pipe 300 is also tightly installed in the diffuser sleeve 200 through the locking nut 400, thereby ensuring the stability of the installation of the waste liquid funnel 500.

[0042] In order to ensure that the diffuser sleeve 200 can stably diffuse pressure in the mounting hole 101 of the test bench 100, the length of the diffuser plate 202 is set to be greater than the thickness of the test bench 100, so that the lower end of the diffuser plate 202 is located below the mounting hole 101, and then the lower end of the diffuser plate 202 can be tightly pressed against the bottom port of the mounting hole 101 when it bends and deforms outward, thereby preventing the locking nut 400 from shaking or falling off in the mounting hole.

[0043] The diffuser plates 202 are arc-shaped plate structures, and there are at least three of them, which are arranged in a circular shape with equal spacing. Figure 7 As shown, there are four diffuser plates 202, which are arranged in a circular shape with equal intervals.

[0044] To ensure the service life of the diffuser sleeve 200, the diffuser sleeve 200 adopts an integrated structure, and the annular pressing sheet 201 and the plurality of diffuser plates 202 at its bottom are processed as one piece. The diffuser sleeve 200 is made of elastic stainless steel or elastic aluminum alloy and has certain wear resistance and corrosion resistance.

[0045] In some of the embodiments, Figure 2 , Figure 4 , Figure 8 and Fig.10 As shown, the straight drain pipe 300 includes an upper locking screw 301, a lower drain pipe 302 and a plurality of oblique pressure blocks 303. The upper screw sleeve 301 and the lower screw sleeve 302 are an integral structure and are made of galvanized steel pipes. The plurality of oblique pressure blocks 303 are fixed to the outer peripheral body at the lower end of the upper screw sleeve 301 by welding.

[0046] The lower end of the upper locking screw 301 is coaxially connected to the lower drain pipe, and a plurality of inclined pressure blocks 303 are arranged at equal intervals along the circumference of the outer peripheral body of the lower end. The plurality of inclined pressure blocks 303 are arranged corresponding to the plurality of introduction grooves 203 and the clamping grooves 204 on the diffuser sleeve 200, and the tops thereof are arranged as inclined surfaces inclined downward.

[0047] The inclined surface at the top of the inclined pressure block 303 is interference-connected with the inclined surface at the lower end of the diffuser sleeve 200, so that when the inclined pressure block 303 is pulled upward, the lower end of the diffuser plate 202 can be obliquely squeezed to expand outward and tightly pressed against the bottom port of the mounting hole 101.

[0048] In addition, in order to facilitate the rapid insertion and placement of the straight drain pipe in the diffuser sleeve 200, the diameter of the lower drain pipe 302 is set to be smaller than the diameter of the upper locking screw pipe 301, so that there is no need to frequently bend down to install it from the bottom of the experimental table 100, and the installation is convenient and quick. And its length is set to 6-10 times the length of the upper locking screw pipe 301, so that it can directly reach the position of the waste liquid collection bucket 600 through the lower drain pipe 302, without taking another pipe to connect the upper locking screw pipe 301.

[0049] The lower end of the straight drainage pipe 300 is connected to the waste liquid collection bucket 600 through a drainage hose 500. The drainage hose 500 is an S-shaped corrugated hose that prevents air leakage, and locking nuts 501 are used at both ends to detachably connect the lower end of the straight drainage pipe 300 and the top opening of the waste liquid collection bucket 600.

[0050] In addition, as needed, a high-efficiency filter can be installed on the waste liquid collection barrel 600 to efficiently adsorb and filter the volatile waste gas produced in the waste liquid collection barrel 600 to protect the laboratory environment air from pollution.

[0051] In some of the embodiments, Figure 2 , Figure 4 and Figure 6 As shown, in order to increase the waste liquid discharge rate, maintain the pressure balance inside and outside the system, and prevent the solvent from evaporating outward at the safety bottle cap 700 where the waste liquid is collected, a one-way valve 800 is also provided at the top of the safety bottle cap 700.

[0052] Specifically, the one-way valve 800 adopts a high-sensitivity one-way air intake valve. When waste liquid is not collected, the one-way air intake valve automatically closes and seals to prevent the gas in the safety bottle cap 700 from evaporating outward, thereby protecting the laboratory environment and the health of the experimenters.

[0053] like Figure 1 , Figure 3 , Figure 5 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the installation and use of the integrated experimental table multi-connector waste liquid collection device are as follows:

[0054] Step 1, installing the diffuser sleeve 200 in the mounting hole 101 of the test bench 100, and making the bottom end of the diffuser sleeve 200 be located below the mounting hole 101;

[0055] Step 2, thread the locking nut 400 on the upper end of the drain straight pipe 300 to assemble the pipe into a whole, and insert the pipe into the diffuser sleeve 200 from the top of the test bench 100, and insert the oblique pressure block 303 into the corresponding position from the introduction groove 203; then, rotate the drain straight pipe 300, and rotate the oblique pressure block 303 at its lower end from the lower end of the introduction groove 203 to the clamping groove 204;

[0056] Step 3: Press the diffuser sleeve 200 with one hand and keep it still. Use the other hand to turn the locking nut 400 to synchronously drive the straight drain pipe to move upward. Use the oblique pressing block 303 to squeeze the diffuser plates 202 around the diffuser sleeve 200 outward and tightly press them against the mounting hole 101, so that the diffuser sleeve 200 and the straight drain pipe are firmly fixed on the experimental table 100.

[0057] Step 4, the lower end of the straight drainage pipe 300 is connected to the waste liquid collection bucket 600 through a drainage hose 500, a safety bottle cap 700 is installed on the top of the straight drainage pipe 300, and a plurality of waste liquid collection pipes 900 and a one-way valve 800 are installed on the safety bottle cap 700;

[0058] Step 5, each of the waste liquid collection tubes 900 is then connected to the waste liquid collection funnels at different workstations of the experimental table 100 through pipelines, and the waste liquid collection funnels can be moved to different experimental workstations for centralized collection of waste liquid as needed.

[0059] In summary, the waste liquid collection device installs at least one waste liquid collection tube 900 on the safety bottle cap 700 threadedly connected to the top of the liquid discharge straight tube 300. The waste liquid collection tube 900 is connected to the waste liquid collection funnels at different workstations on the experimental table through pipelines, so that a liquid discharge straight tube 300 and a waste liquid collection bucket 600 are used to realize the centralized collection of waste liquid at multiple different workstations, which greatly reduces the number of waste liquid collection equipment to be installed and the installation workload, reduces the equipment investment cost, and can move the waste liquid collection funnel to different experimental workstations as needed, thereby improving the utilization efficiency of the waste liquid collection equipment and making it flexible and convenient to use.
