Technical Field

[0001] The utility model relates to the technical field of wastewater sedimentation, and particularly relates to a sedimentation device for laboratory wastewater. Background Art

[0002] When conducting chemical experiments in the laboratory, a large amount of experimental wastewater will be generated. In order to reduce the pollution of the wastewater, it is necessary to carry out sedimentation treatment on the wastewater before discharging it. Wastewater sedimentation is to use physical, chemical, and biological methods to treat the wastewater, purify the wastewater, reduce pollution, so as to achieve wastewater recycling and reuse and make full use of water resources;

[0003] In the patent application No. 202121891534.X, a sedimentation device for laboratory wastewater is disclosed. "A fixed rod is fixedly connected to the left outer wall of the primary sieve cylinder, the left side of the fixed rod is fixedly connected to the left inner wall of the sedimentation cylinder, a primary filter ring net is fixedly connected to the bottom inner wall of the primary sieve cylinder, the primary filter ring net is located below the water inlet pipe, the right bottom end of the primary sieve cylinder is fixedly sleeved with a primary sieve pipe, the top end of the primary sieve pipe is located between the outer wall of the primary filter ring net and the inner wall of the primary sieve cylinder, the bottom end of the primary sieve pipe is located above the reaction cylinder, and a fixed rod is also fixedly connected to the rear side wall of the reaction cylinder." "The wastewater discharged through the primary sieve pipe enters the reaction cylinder, and then a flocculant is added into the feeding hopper.

At the lower end of the reaction cylinder 6 and inside the sedimentation cylinder 1, a liquid receiving hopper 9 is provided. A drain pipe 10 with a switch valve is connected to the lower end face of the liquid receiving hopper 9. A support frame 12 is connected to the outside of the sedimentation cylinder 1.

[0027] Specifically, first, the laboratory wastewater is injected into the sedimentation cylinder 1 through the water adding pipe 3. The wastewater flows into the sieve frame 7 in the primary sieve cylinder 5 through the water adding pipe 3. The wastewater preliminarily filtered by the sieve frame 7 is discharged from the outlet at the bottom end of the primary sieve cylinder 5. Through the sieve frame 7, the large particles in the laboratory wastewater are effectively pre-filtered, thereby effectively improving the sedimentation efficiency of the laboratory wastewater. After the wastewater enters the reaction cylinder 6, then a flocculant is added into the feeding pipe 4. The flocculant enters the reaction cylinder 6 through the feeding pipe 4 and mixes with the wastewater for reaction. Under the action of the flocculant, the suspended particles in the wastewater begin to coagulate and settle. After the reaction is completed, the switch valve is opened by rotating the knob, so that the sedimented wastewater in the reaction cylinder 6 is discharged. The discharged wastewater falls into the liquid receiving hopper 9. Finally, the switch valve is opened, and the wastewater finally discharges from the drain pipe 10 out of the sedimentation cylinder 1.

[0028] The present utility model provides a sedimentation device for laboratory wastewater as shown in Figures 2 - 4 the figure.

[0029] The fastening part includes a connecting block 811, an empty slot 812, an elastic block 813, an outer plate 814, a clamping block 815 and a clamping slot 816. The connecting block 811 is connected to the outer wall of the reaction cylinder 6. The empty slot 812 is opened inside the connecting block 811. The elastic block 813 is connected inside the empty slot 812. The outer plate 814 is connected to the free end of the elastic block 813. The clamping block 815 is connected to the side of the outer plate 814 close to the annular block 81. The clamping slot 816 is opened inside the annular block 81.

After the wastewater is discharged, first, hold and pull the outer plate 814 outward. At this time, the clamping block 815 moves out of the clamping groove 816, and the elastic block 813 moves backward. Finally, pull up the ring block 81, and the funnel 82 containing the agglomerated particles can be taken out, and the agglomerated particles can be quickly cleaned out without reaching into the reaction cylinder 6 to clean the agglomerated particles, enhancing the convenience of cleaning the reaction cylinder 6, and also avoiding the drawback that the agglomerated particles remain at the corners of the reaction cylinder 6, ensuring the thorough cleaning of the reaction cylinder 6 and not affecting the subsequent wastewater treatment. After cleaning, install the funnel 82 into the reaction cylinder 6 according to the above operation, which is convenient for subsequent wastewater treatment.

[0033] The present utility model provides a sedimentation device for laboratory wastewater as shown in Figure 2 and Figure 5 The sedimentation cylinder 1 is provided with an adjustable connection structure 11, and the adjustable connection structure 11 includes a main driving part and a limiting part.

[0034] The main driving part includes a first fixing block 111, a threaded block 113, a lead screw 114 and a positive and negative motor 115.

[0036] Through the above technical solution:

[0037] When picking up and placing the funnel 82, turn on the forward and reverse motor 115. The forward and reverse motor 115 drives the lead screw 114 to rotate counterclockwise. At this time, the threaded block 113 is in threaded cooperation with the lead screw 114, driving the threaded block 113 to move upward. At the same time, the limit block 116 moves upward on the outside of the limit rod 117, and then the primary sieve cylinder 5 can be driven to rise. This operation can adjust by increasing the distance between the reaction cylinder 6 and the primary sieve cylinder 5, thereby increasing the picking and placing space of the funnel 82, avoiding the situation that the picking and placing space is insufficient due to the fixed value of the distance, resulting in difficult picking and placing of the funnel 82, ensuring the picking and placing effect of the funnel 82, and improving the use effect of the sedimentation device. In addition, by rotating the lead screw 114 clockwise, the primary sieve cylinder 5 can be lowered to reduce the distance from the reaction cylinder 6.
