DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0025] like Figure 1 and Figure 2 As shown, the present application provides a waste liquid collection device for a detector, comprising: a waste liquid collection barrel 1, a support plate 2 and a fastening unit.

[0026] The waste liquid collection barrel 1 is placed on the support plate 2 , and a waste liquid guide pipe 110 is movably connected to the top of the waste liquid collection barrel 1 . The fastening unit is also arranged on the support plate 2 and movably abuts against the waste liquid collection barrel 1 .

[0027] The fastening unit includes a telescopic motor 310, a telescopic rod 320, an arc-shaped fastening clamp 330 and a positioning plate 340 that are symmetrical about the center of the waste liquid collection barrel 1. The telescopic motor 310 is fixedly arranged on the support plate 2. One end of the telescopic rod 320 is fixedly connected to the telescopic motor 310, and the other end of the telescopic rod 320 is connected to the outer center of the arc-shaped fastening clamp 330. The inner side of the arc-shaped fastening clamp 330 faces the bottom outer wall of the waste liquid collection barrel 1, and the telescopic rod 320 passes through the positioning plate 340. A handle 210 is arranged on one side of the support plate 2, and a roller 220 is arranged at the bottom of the support plate 2.

[0028] Specifically, the present application takes a liquid chromatograph as an example to explain the principle of the waste liquid collection device for the detector provided by the present application, and the present application is also applicable to the waste liquid collection of other detection instruments. A waste liquid guide tube 110 is movably connected to the top of the waste liquid collection barrel 1, and the end of the waste liquid guide tube 110 away from the waste liquid collection barrel 1 is connected to the waste liquid outlet of the liquid chromatograph, and the waste liquid is transported to the waste liquid collection barrel 1, and then the waste liquid collection barrel 1 is transported to the waste liquid treatment unit through the support plate 2 for waste liquid treatment.

[0029] The fastening unit is used to fasten the waste liquid collection barrel 1 placed on the support plate 2 to prevent the waste liquid collection barrel 1 from tipping over or shifting when being transported on the support plate 2, thereby improving the safety of the waste liquid collection process. The fastening unit includes a telescopic motor 310, a telescopic rod 320, an arc-shaped fastening clamp 330 and a positioning plate 340 that are symmetrical about the center of the waste liquid collection barrel 1. The telescopic motor 310 causes the telescopic rod 320 to extend and retract while rotating. When the waste liquid collection barrel 1 needs to be fastened, the two symmetrically arranged telescopic motors 310 are turned on to extend the telescopic rod 320, and the telescopic rod 320 is connected to the outer center of the arc-shaped fastening clamp 330. In this way, the two telescopic rods 320 are extended to push the arc-shaped fastening clamps 330 connected thereto to move toward the waste liquid collection barrel 1. The two arc-shaped fastening clamps 330 gradually approach the waste liquid collection barrel 1 until they abut against the outer wall of the waste liquid collection barrel 1, and the telescopic motor 310 is turned off. The waste liquid collection barrel 1 is fastened by the arc-shaped fastening clamp 330, so that the waste liquid collection barrel 1 and the support plate 2 are also more fastened. During the transportation of the waste liquid collection barrel 1 after collecting the waste liquid, the shaking and displacement of the waste liquid collection barrel 1 are avoided, the safety of the waste liquid collection barrel 1 during transportation is improved, and the collection and transportation efficiency of the waste liquid is improved.

[0030] The telescopic rod 320 passes through the positioning plate 340, and the positioning plate 340 is used to limit the direction of the telescopic rod 320 during the telescopic process, which is beneficial for the telescopic rod 320 to be telescopic in a straight direction, and at the same time makes the abutment between the arc-shaped fastening clamp 330 and the telescopic rod 320 more stable, which is beneficial to improve the abutment force of the arc-shaped fastening clamp 330 on the waste liquid collection barrel 1, thereby improving the stability of the waste liquid collection barrel 1.

[0031] A handle 210 is provided on one side of the support plate 2 to facilitate pushing the support plate 2 , and a roller 220 is provided at the bottom of the support plate 2 to make the transportation process of the waste liquid collection barrel 1 more time-saving and labor-saving.

[0032] The present application realizes the efficient collection and transportation of liquid chromatograph waste liquid through the above scheme. By connecting the waste liquid guide tube between the liquid chromatograph and the waste liquid collection barrel, it is convenient to collect the waste liquid of the liquid chromatograph. By setting a fastening unit, the waste liquid collection barrel placed on the support plate is fastened to prevent the waste liquid collection barrel from tipping over or shifting when being transported on the support plate, thereby improving the safety during the waste liquid collection process. The fastening unit includes a telescopic motor, a telescopic rod arc-shaped fastening clamp and a positioning plate symmetrical about the center of the waste liquid collection barrel. The telescopic motor extends the telescopic rod, so that the two telescopic rods can extend and respectively push the arc-shaped fastening clamps abutting therewith to move in the direction of the waste liquid collection barrel until they abut against the outer wall of the waste liquid collection barrel. The waste liquid collection barrel is fastened by the arc-shaped fastening clamp, so that the waste liquid collection barrel and the support plate are also more fastened. In the process of transporting the waste liquid collection barrel after collecting the waste liquid, the shaking and displacement of the waste liquid collection barrel are avoided, thereby improving the safety during the transportation of the waste liquid collection barrel, and at the same time improving the collection and transportation efficiency of the waste liquid.

[0033] like Figure 1 As shown, optionally, a high-position stabilizing plate 350 is disposed in the middle of the top of the arc-shaped fastening clamp 330 .

[0034] Specifically, the high-position stabilizing plate 350 is disposed in the middle of the top of the arc-shaped fastening clamp 330. In this way, during transportation, if the height of the waste liquid collection barrel 1 is relatively high, the high-position stabilizing plate 350 can enable the fastening center of the fastening unit on the waste liquid collection barrel 1 to move upward, thereby further avoiding the tipping or displacement of the waste liquid collection barrel 1 and improving the transportation stability of the waste liquid collection barrel 1.

[0035] like Figure 2 As shown, optionally, a limiting groove 331 is provided at the location where the outer center of the arc-shaped fastening clamp 330 is connected to the telescopic rod 320 .

[0036] Specifically, the end of the telescopic rod 320 is located in the limiting groove 331 , and this arrangement makes the telescopic rod 320 more stable during the process of pushing the arc-shaped fastening clamp 330 .

[0037] like Figure 3 As shown, optionally, a shock absorbing plate 4 is provided between the waste liquid collecting barrel 1 and the supporting plate 2 .

[0038] Specifically, the provision of the shock-absorbing plate 4 further improves the stability of the waste liquid collection barrel 1 , avoids contact between the waste liquid collection barrel 1 and the support plate 2 , and reduces friction on the bottom of the waste liquid collection barrel 1 .

[0039] like Figure 3As shown, optionally, the waste liquid collection barrel 1 is also connected to a negative pressure unit, which includes an exhaust pipe 510, a negative pressure pump 520 and a gas processor 530. The top of the waste liquid collection barrel 1 is connected to the gas processor 530 via the exhaust pipe 510 via the negative pressure pump 520.

[0040] Specifically, the waste liquid generated by the liquid chromatograph usually contains a large amount of organic solvents, which are easy to volatilize. During the waste liquid collection process, the volatile organic solvent in the waste liquid collection barrel 1 will escape from the waste liquid collection barrel 1. The volatile organic solvent gas is pumped into the gas processor 530 through the gas pipe 510 by the negative pressure pump 520, thereby avoiding the escape of waste gas and keeping the pressure in the waste liquid collection barrel 1 stable.

[0041] like Figure 3 As shown, optionally, a waste liquid valve 120 is provided on the waste liquid diversion pipe 110 , and a liquid level meter 130 is provided in the waste liquid collection barrel 1 .

[0042] Specifically, the liquid level meter 130 is used to detect the liquid level in the waste liquid collection barrel 1, and controls whether to input the waste liquid into the waste liquid collection barrel 1 by controlling the opening and closing of the waste liquid valve 120. At the same time, through the liquid level indication of the liquid level meter 130, the waste liquid transport into the waste liquid collection barrel 1 is timely closed to avoid overflow of the waste liquid in the waste liquid collection barrel 1.

[0043] Optionally, a filter screen 140 is provided in the waste liquid collection barrel 1 .

[0044] Specifically, the filter screen 140 can filter the solids in the waste liquid to achieve solid-liquid separation, which is beneficial for separate treatment of the waste liquid and solid waste.

[0045] The technical solution of the present application is described in detail below with reference to specific embodiments.

[0046] The operation flow of the waste liquid collection device for the detector in this embodiment during specific operation is as follows:

[0047] The waste liquid guide pipe 110 transfers the waste liquid in the liquid chromatograph to the waste liquid collection barrel 1. During the waste liquid collection process, the filter screen 140 filters the waste liquid entering the waste liquid collection barrel 1, and at the same time, the volatile organic solvent gas is pumped to the gas processor 530 through the air pipe 510 by the negative pressure pump 520, thereby preventing the escape of waste gas. Through the liquid level indication of the liquid level meter 130, the waste liquid transport to the waste liquid collection barrel 1 is promptly closed to prevent the waste liquid in the waste liquid collection barrel 1 from overflowing. Then, the waste liquid collection barrel 1 is placed on the support plate 2, and the waste liquid collection barrel 1 is fastened by the fastening unit, and finally, the waste liquid collection barrel 1 is transported to the waste liquid treatment unit through the support plate 2 for waste liquid treatment.

[0048] The two symmetrically arranged telescopic motors 310 are turned on to extend the telescopic rods 320, which are connected to the outer center of the arc-shaped fastening clamps 330. The two telescopic rods 320 are extended to push the arc-shaped fastening clamps 330 connected thereto to move toward the waste liquid collection barrel 1. The two arc-shaped fastening clamps 330 gradually approach the waste liquid collection barrel 1 until they abut against the outer wall of the waste liquid collection barrel 1, and the telescopic motors 310 are turned off. The waste liquid collection barrel 1 is fastened by the arc-shaped fastening clamps 330 and the high-position stabilizing plate 350, so that the waste liquid collection barrel 1 and the support plate 2 are also more fastened, thereby preventing the waste liquid collection barrel 1 from shaking and displacement.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, 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 application.
