[0002] Laboratory sewage refers to wastewater generated in various laboratory activities such as scientific research, teaching, testing, and analysis. These wastewaters may contain various chemical substances, biological agents, heavy metals, etc. If they are discharged without proper treatment, they will pose a serious threat to the environment and human health. Laboratory sewage cannot usually be discharged directly into the public sewer system due to its complex composition and needs to undergo special treatment to meet discharge standards.

[0003] At present, when treating laboratory wastewater, the wastewater is added into a treatment cylinder, and a treatment agent is added, and then the wastewater is stirred and mixed with a stirring structure inside the treatment cylinder to achieve reaction treatment of the wastewater. However, the wastewater inside the existing treatment cylinder is stirred by the stirring structure in a single direction, which makes it difficult to quickly and evenly mix the reaction, and the treatment efficiency is low.

[0035] Among them, see Figure 3 As shown, the stirring structure includes a stirring rod 15 and a plurality of stirring blades 16. One end of the stirring rod 15 is installed on the output end of the first motor 7, and the plurality of stirring blades 16 are installed outside the stirring rod 15. After the first motor 7 is started by the controller 3, the stirring rod 15 can be driven to rotate by the output end of the first motor 7, and then the stirring blades 16 can be used to stir the laboratory sewage inside the treatment cylinder 2 to speed up the treatment efficiency.

[0036] See also Figure 1 and Figure 2 As shown, the lifting components are symmetrically provided with two groups, and each group of lifting components includes:

[0037] A telescopic rod 4, which is installed on one side of the upper end surface of the processing table 1. The telescopic rod 4 can be an electric telescopic rod, a hydraulic cylinder or a pneumatic cylinder;

[0038] The convex plate 6 is fixed to the side of the cylinder cover 5 , and the top end of the telescopic rod 4 is installed on the lower end surface of the convex plate 6 .

[0039] Specifically, by starting the telescopic rod 4 using the controller 3 , the telescopic rod 4 can be extended and retracted, thereby causing the cylinder cover 5 to rise or fall.

[0040] In addition, see Figure 1 as well as Figure 4-Figure 5 As shown, a rotating assembly is provided between the processing cylinder 2 and the processing table 1, and the rotating assembly includes a passive rotating part and an active rotating part. The active rotating part is used to drive the processing cylinder 2 to rotate in the direction opposite to the rotation direction of the stirring structure, and the passive rotating part includes a fixed annular bar 13 and a movable annular bar 17.

[0041] Among them, in the specific implementation of the present utility model, refer to Figure 1 As shown, the active rotating part includes:

[0042] A second motor 10, the second motor 10 is mounted on the lower end surface of the processing table 1;

[0043] Gear 11, gear 11 is mounted on the shaft at the output end of the second motor 10;

[0044] The annular rack 12 is fixed to the outside of the processing tube 2 and is located at the lower end surface of the processing table 1 . The gear 11 is meshed and connected to the annular rack 12 .

[0045] Based on the above technical solutions:

[0046] During specific use, the laboratory sewage and the treatment agent can be poured into the sewage bucket 9 first, and then guided into the treatment tube 2 through the water pipe 8. Subsequently, the controller 3 can be used to start the first motor 7 and the second motor 10, and the first motor 7 can be used to drive the stirring structure for stirring. The output end of the second motor 10 can be used to drive the gear 11 to rotate, and then drive the meshing annular rack 12 to rotate, thereby driving the treatment tube 2 to rotate. By utilizing the opposite movement of the treatment tube 2 and the stirring structure, the uniformity of the mixing of the sewage and the treatment agent inside the treatment tube 2 can be effectively improved, and the treatment efficiency can be improved. When the stirring structure is stirring, the controller 3 can be used to control the orderly lifting and lowering of the telescopic rod 4, that is, the sewage and the treatment agent can be driven to surge up and down while the stirring structure rotates and stirs, which can further improve the sewage treatment efficiency.

[0047] When the processing cylinder 2 rotates, the movable annular bar 17 rotates in the annular slide groove 18, so as to prevent the processing cylinder 2 from moving up and down.

[0048] In addition, when it is necessary to clean the floccules generated after the reaction inside the treatment tube 2, the controller 3 can be used to completely separate the stirring structure from the treatment tube 2, thereby facilitating quick cleaning without obstruction.

[0049] Also, see Figure 4 As shown, a filter element 14 is detachably arranged inside the dirty water hopper 9 .

[0050] See also Figure 6 As shown, the filter element 14 includes:

[0051] A funnel 141 is arranged inside the sewage bucket 9, and a filter screen 142 is arranged at the bottom opening of the funnel 141;

[0053] Specifically, when pouring laboratory sewage into the sewage bucket 9, the filter net 142 at the bottom of the funnel 141 can be used to filter out suspended solids, grease and other large particles in the sewage. By lifting the pull ring 144 at the top of the pull rod 143, the funnel 141 can be removed to clean the solid matter inside.

[0054] In addition, the following explanation can be made for adding sewage and treatment agent from the sewage bucket 9: to avoid obstruction by solid matter in the sewage, the treatment agent can be poured in first; or when pouring the treatment agent, the filter element 14 can be removed, and when pouring the sewage, the filter element 14 can be installed.
