DETAILED DESCRIPTION

[0020] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0021] Embodiments of the present utility model: Figure 1-Figure 5 As shown, a chemical laboratory waste liquid barrel with a filtering structure comprises a barrel body 1, a turntable 2 is rotatably installed at the bottom of the barrel body 1, a mounting shaft 3 is fixedly provided at the center position of the top surface of the turntable 2, a waste liquid barrel 4 and a waste sample barrel 5 are installed on the mounting shaft 3, a filter screen 6 is provided at the bottom of the waste sample barrel 5, a liquid outlet 7 is formed on the barrel body 1, a liquid outlet hole 8 is opened on the side wall of the waste liquid barrel 4, and a barrel cover 11 is installed on the top of the waste sample barrel 5.

[0022] The cylinder 1 is a cylindrical cylinder, and a mounting column 19 is formed at the center of the bottom plate of the cylinder 1, and a bearing 20 is installed on the mounting column 19. A bearing mounting groove is formed at the center of the bottom of the turntable 2. The bearing mounting groove and the outer ring surface of the bearing 20 are interference fit, and the mounting column 19 and the inner ring surface of the bearing 20 are interference fit. The arrangement of the bearing 20 can make the turntable 2 rotate more smoothly. The filter 6 plays a filtering role, leaving the waste sample in the waste sample barrel 5, and the waste liquid leaks into the waste liquid barrel 4 for storage, realizing solid-liquid separation.

[0023] In a specific embodiment, the mounting shaft 3 is a cross-shaped shaft, that is, the cross-section of the mounting shaft 3 is a cross-shaped shape, and a cross-shaped mounting hole is provided in the center of the waste liquid barrel 4 and the waste sample barrel 5. Through such an arrangement, the mounting shaft 3, the waste liquid barrel 4 and the turntable 2 can rotate synchronously when the waste sample barrel 5 is rotated.

[0024] Furthermore, four waste liquid containing chambers 9 of equal size are formed in the waste liquid barrel 4, and a liquid outlet hole 8 is provided on the upper side wall of each waste liquid containing chamber 9. Four sealing rings 10 are fixedly provided on the outer wall of the waste liquid barrel 4, and the four sealing rings 10 are respectively coaxially arranged with the four liquid outlet holes 8. A through hole 12 is provided at the connection position between the liquid outlet nozzle 7 and the cylinder body 1, and the height of the sealing ring 10 is the same as the height of the through hole 12.

[0025] With this structural design, the waste liquid barrel 4 can be rotated to align the liquid outlet hole 8 and the sealing ring 10 on one of the waste liquid receiving chambers 9 with the through hole 12, so that the waste liquid inside can be poured out through the liquid outlet nozzle 7. Of course, if none of the four sealing rings 10 are aligned with the through hole 12, the sealing rings 10 on the four waste liquid receiving chambers 9 are in contact with the inner wall of the barrel 1, and the four waste liquid receiving chambers 9 are sealed through the inner wall of the barrel 1. The sealing ring 10 is made of rubber, and of course other elastic materials that are not prone to chemical reactions can also be used.

[0026] Furthermore, the waste liquid barrel 4 is located in the barrel 1, the top surface of the waste liquid barrel 4 is flush with the top surface of the barrel 1, the outer diameter of the waste liquid barrel 4 is slightly smaller than the inner diameter of the barrel 1, so that the waste liquid barrel 4 can rotate smoothly in the barrel 1, and the outer diameter of the waste sample barrel 5 is equal to the outer diameter of the barrel 1. Four waste sample receiving chambers 13 are formed in the waste sample barrel 5, and the four waste sample receiving chambers 13 are connected to the four waste liquid receiving chambers 9 respectively.

[0027] In this embodiment, the cross-sectional shapes and sizes of the four waste sample holding chambers 13 and the four waste liquid holding chambers 9 are exactly the same, and their cross-sectional shapes are all fan-shaped. By setting up four waste sample holding chambers 13 and four waste liquid holding chambers 9, four types of waste liquids and waste samples can be stored, which can usually meet the needs of laboratory use. This can solve the problem of large space occupied by preparing multiple waste liquid barrels in the prior art. It should be noted that setting up four waste sample holding chambers 13 and four waste liquid holding chambers 9 is only a preferred solution of this embodiment. Of course, more or fewer waste sample holding chambers 13 and waste liquid holding chambers 9 can be set according to actual needs.

[0028] Furthermore, four first connection protrusions 14 are formed on the bottom surface of the waste sample barrel 5, and the four first connection protrusions 14 are respectively plugged and connected with the top ends of the four waste liquid receiving chambers 9. Sealing rings are arranged on the outer walls of the four first connection protrusions 14, and the first connection protrusions 14 can be effectively connected to prevent liquid leakage and slow down the volatilization speed of the waste liquid.

[0029] Preferably, four upper marking arrows 15 are formed on the outer wall of the waste sample barrel 5, and one lower marking arrow 16 is formed on the outer wall of the cylinder body 1. In this embodiment, four upper marking arrows 15 are provided to correspond to four waste sample holding chambers 13 and waste liquid holding chambers 9 respectively. When the upper marking arrows 15 are aligned with the lower marking arrows 16, a sealing ring 10 on the waste liquid holding chamber 9 is aligned with the through hole 12, and the waste liquid can be poured out through the liquid outlet 7. When none of the four upper marking arrows 15 are aligned with the lower marking arrows 16, the four sealing rings 10 are in contact with the inner wall of the cylinder body 1, and the four waste liquid holding chambers 9 are in a sealed state, and the waste liquid will not spill out.

[0030] Furthermore, four second connection protrusions 17 are formed on the bottom surface of the barrel cover 11, and the four second connection protrusions 17 are plug-connected with the upper ends of the four waste sample receiving chambers 13, respectively, and a handle 18 is fixed on the top surface of the barrel cover 11. The second connection protrusions 17 also play a sealing role.

[0031] The working principle of the utility model is as follows: when in use, the barrel cover 11 is opened by the handle 18, and four labels can be correspondingly affixed on the outer wall of the waste sample barrel 5 according to the needs, marking the names of the waste samples contained in the corresponding waste sample holding chamber 13, pouring the waste samples and waste liquid after the experiment into the corresponding waste sample holding chamber 13, and the waste liquid leaks through the filter 6 to the waste liquid holding chamber 9 below for storage, and the waste samples are left in the waste sample holding chamber 13, and the barrel cover 11 is covered. When the waste samples are full, the waste sample barrel 5 can be lifted up to remove it from the mounting shaft 3, and the waste samples can be poured out for centralized treatment. When the waste liquid is full, the waste sample barrel 5 is rotated by the handle 18 so that the corresponding waste liquid holding chamber 9 is aligned with the liquid outlet 7, and whether it is aligned can be judged by whether the upper marking arrow 15 is aligned with the lower marking arrow 16. After pouring out the waste liquid, the waste sample barrel 5 is rotated so that the four upper marking arrows 15 are not aligned with the lower marking arrow 16, so as to achieve the sealing of the four waste liquid holding chambers 9 and prevent the waste liquid from volatilizing.

[0032] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
