[0002] With the development of science and technology, the demand for chemical laboratories is increasing. From the distribution of laboratories, they are mainly concentrated in schools and scientific research institutions. Chemical experiments generally produce waste and waste liquid. In the existing technology, waste and waste liquid are generally classified and stored using storage devices, and then they are processed in a centralized manner after a large amount of materials are stored.

[0003] Such treatment equipment in the prior art has many treatment methods, and each different chemical waste needs to be treated by a different treatment method, such as neutralization treatment: for acidic or alkaline waste, neutralization treatment can be carried out to make its pH value close to neutral before discharge, incineration treatment: incineration in special equipment to convert organic waste into harmless substances.

In the prior art, flocculation may be carried out when treating acidic or alkaline waste, and precipitates are often produced. In the prior art, when treating precipitates, the flocculants are deposited at the lower end of the entire treatment equipment, which is troublesome to clean up. If the flocculants are discharged through a pipeline, they are easily not discharged completely, which easily affects work efficiency. Therefore, an improved chemical experimental waste treatment device is needed to address this problem. Utility Model Content

[0023] A first motor 11 is fixedly arranged at the middle part of the lower end of the reaction tank 3 through a mounting seat, and the output shaft end of the first motor 11 is transmission-connected to the rotating shaft where the rotating rod 7 is located through a coupling, and the rotating rod 7 can be conveniently driven to rotate by the first motor 11; thereby, the scraper 8 can be driven to rotate, and at this time, due to the inclined arrangement of the reaction tank 3, all the flocculants will be deposited in the direction of the reaction tank 3 close to the discharge pipe 5 under the action of gravity; thus, as the scraper 8 rotates, the scraper 8 will drive the flocculants deposited at the oblique lower part of the reaction tank 3 to the oblique upper slag discharge port 4, and then discharge them from the slag discharge port 4, and each time the device is used to process waste liquid, the liquid level of the waste liquid should be lower than the height of the slag discharge port 4, and different amounts of waste liquid can be processed at one time according to the degree of inclination of the reaction tank 3 and the diameter of the reaction tank 3;

[0024] The upper end of the reaction tank 3 is fixedly provided with a crossbeam 12, and a stirring rod 13 is movably provided on one side of the crossbeam 12 through a rotating shaft. The stirring rod 13 can be used to stir the waste liquid when the reaction reagent is added during the treatment.

[0027] Working principle: When using this device, the waste material to be treated can be conveniently injected into the reaction tank 3 through the feed port 16, and then the corresponding reaction agent and flocculation agent can be added. Then, due to the inclined setting of the reaction tank 3, all the flocculants will be deposited in the direction of the reaction tank 3 close to the discharge pipe 5 under the action of gravity; in this way, the scraper 8 can be driven to rotate by the first motor 11. As the scraper 8 rotates, the scraper 8 will drive the flocculants deposited at the lower part of the reaction tank 3 to the upper part of the slag discharge port 4, and then discharge them from the slag discharge port 4; in this way, it is more convenient to clean the flocculants inside the reaction tank 3, and the cleaning is more thorough because the scraper 8 continuously rotates to bring out the flocculants; at the same time, the flocculant cleaning and stirring reaction can be carried out simultaneously, and the continuous rotation of the scraper 8 can not only stir the waste liquid, but also continuously carry away the flocculants.

[0028] Each time the device processes waste liquid during use, the liquid level of the waste liquid should be lower than the height of the slag discharge port 4. Depending on the inclination of the reaction tank 3 and the diameter of the reaction tank 3, different amounts of waste liquid can be processed at one time.
