Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a flocculant mixing device for wastewater treatment experiments. Background Technology

[0002] With rapid economic development, a large amount of wastewater is generated in both daily life and production processes. As times progress, wastewater treatment is becoming increasingly important, requiring not only more advanced treatment equipment but also more advanced treatment technologies, all of which rely on continuous wastewater treatment experiments.

[0003] Flocculants are a very important wastewater treatment agent. Each flocculant needs to be tested in the laboratory before it is put into use, or when treating wastewater with different components, in order to find the most suitable flocculant and to provide technical support for the development of new flocculants.

[0004] In laboratory wastewater treatment, the wastewater volume is often small, but the experimental samples are numerous. When mixing flocculants with wastewater, it is necessary to use a mixer to mix a large number of samples in batches. Since the existing mixers can only mix one sample at a time, it is often necessary to use multiple mixers simultaneously, which still consumes a lot of time and affects the experimental progress. This needs to be improved. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a flocculant mixing device for wastewater treatment experiments, which solves the problem that existing mixers in laboratory wastewater treatment can only mix one sample at a time, resulting in significant time consumption and impacting experimental progress.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A flocculant mixing device for wastewater treatment experiments includes a cantilever mixer. An extension plate is fixedly installed on the base of the cantilever mixer. Support feet are installed on the bottom of both the extension plate and the base. A guide column is vertically fixed on the upper surface of the extension plate. A support plate is installed on the extension plate and slidably sleeved on the guide column. The support plate is movably installed on the guide column by a locking mechanism.

[0008] A bracket is provided above the support plate, and a damper is installed on the bracket. The lower end of the bracket movably passes through the support plate and is fixed on the extension plate. Multiple crankshafts are rotatably installed on the bracket, and the multiple crankshafts are connected by a connecting rod transmission. A stirring shaft that is inserted into the container placed on the support plate is detachably installed at the lower end of the crankshaft.

[0009] The bracket is also rotatably connected to a rotating shaft that is driven by the drive shaft of the cantilever mixer. A rotating wheel is fixedly installed on the surface of the rotating shaft, and an eccentric shaft is fixed at the bottom of the rotating wheel. The connecting rod is installed on the eccentric shaft.

[0010] Preferably, four guide posts are respectively arranged at the four corners of the support plate. The locking mechanism includes four pins. The pins are C-shaped and movably engaged at both ends of the support plate. The upper part of the pin is horizontally movably inserted into the guide sleeve fixed on the support plate. The lower part of the pin is horizontally inserted into the positioning hole at the corresponding position on the guide post. A handle is fixed between two pins on the same side of the support plate.

[0011] Preferably, a stop block is fixed at the upper end of the guide post, and a compression spring is movably sleeved on the guide post between the stop block and the support plate.

[0012] Preferably, the damper includes a housing and a counterweight disposed inside the housing, wherein the top and bottom of the counterweight are connected to the top and bottom of the inner wall of the housing by traction springs.

[0013] Preferably, the dampers are symmetrically installed on both sides of the bracket near the top.

[0014] Preferably, the drive shaft and the rotating shaft, as well as the stirring shaft and the crankshaft, are connected by quick-release clamps.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention installs a rotating wheel on a shaft connected below the drive shaft of an existing cantilever mixer. Multiple crankshafts are driven by an eccentric shaft and connecting rod. These crankshafts are connected to a mixing shaft, allowing for simultaneous and uniform mixing of multiple wastewater samples and flocculants. This not only reduces the cost of purchasing mixing equipment but also saves a significant amount of time and improves mixing efficiency. It solves the problem in existing technologies where existing mixers can only mix one sample at a time during laboratory wastewater treatment, resulting in significant time consumption and impacting experimental progress.

[0026] Four guide posts 4 are respectively set at the four corners of the support plate 5. The locking mechanism 6 includes four pins 601. The pins 601 are C-shaped and are movably engaged at both ends of the support plate 5. The upper part of the pin 601 is horizontally movably inserted into the guide sleeve 16 fixed on the support plate 5. The lower part of the pin 601 is horizontally inserted into the positioning hole at the corresponding position on the guide post 4. A handle 602 is fixed between two pins 601 on the same side of the support plate 5.

[0027] A bracket 7 is provided above the support plate 5. A rotating shaft 13, which is rotatably connected to the drive shaft 102 of the cantilever mixer 1, is also rotatably connected to the bracket 7. A rotating wheel 14 is fixedly installed on the surface of the rotating shaft 13. An eccentric shaft 15 is fixed at the bottom of the rotating wheel 14. A connecting rod 10 is installed on the eccentric shaft 15.

[0028] A damper 8 is installed on the bracket 7. The damper 8 includes a housing 801 and a counterweight 802 set inside the housing 801. The top and bottom of the counterweight 802 are connected to the top and bottom of the inner wall of the housing 801 by traction springs 803. The damper 8 is symmetrically installed on both sides of the bracket 7 near the top.

[0029] The lower end of the bracket 7 moves through the support plate 5 and is fixed on the extension plate 2. Multiple crankshafts 9 are rotatably mounted on the bracket 7, and the multiple crankshafts 9 are connected to each other by a connecting rod 10.

[0030] Working principle:

[0031] By removing the locking mechanism 6, the support plate 5 can be moved downwards for placing and removing containers 11 containing sewage. After the support plate 5 is fixed by the locking mechanism 6, flocculant is added to the container 11. The cantilever mixer 1 drives the rotating shaft 13 and the rotating wheel 14 to rotate via a drive shaft 102. The rotating wheel 14 can drive multiple sets of crankshafts 9 to rotate simultaneously via an eccentric shaft 15 and a connecting rod 10. The multiple sets of crankshafts 9 can mix the sewage and flocculant in the multiple sets of containers 11 respectively through the corresponding stirring shaft 12, shortening the time of repeated mixing and improving efficiency.
