[0002] Environmental engineering chemical wastewater refers to wastewater containing chemical substances generated in industrial, agricultural and medical production activities. If these wastewaters are discharged directly into the natural environment without treatment, they will cause serious water pollution problems. Chemical wastewater is mainly generated by chemical production, experimental activities, and daily life.

[0003] In the traditional technical context, chemical wastewater treatment usually involves adding chemical wastewater and reactants into a reaction barrel, and then carrying out a chemical reaction under the stirring of a stirring rod. However, since the unsealed reaction barrel is easily splashed with liquid on the workers when stirred with a stirring rod, wastewater treatment is dangerous.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 4 A chemical sewage treatment device for environmental engineering includes a bottom plate 1, a pair of support frames 2 are fixedly connected to the top of the bottom plate 1, the same treatment barrel 3 is fixedly connected to the opposite side walls of the two support frames 2, an outlet pipe 4 is fixedly installed on the treatment barrel 3, and a matching sealing cover 5 is arranged above the treatment barrel 3; the outlet pipe 4 is used to discharge the treated water, and the design of the sealing cover 5 ensures that the chemical reaction is carried out in a closed environment, thereby avoiding possible pollution and danger.

[0023] The sealing cover 5 is provided with a stirring structure for stirring the material in the processing barrel 3, and the support frame 2 is provided with a moving structure for moving the sealing cover 5. The stirring structure is specially designed for stirring the material in the processing barrel 3 to ensure that the material can fully react and improve the processing efficiency; the moving structure is used to move the sealing cover 5, thereby realizing the opening, closing and sealing of the processing barrel 3.

[0024] The moving structure includes a slide groove 6 provided on the opposite side walls of the two support frames 2, and the same sliding seat 7 is slidably connected to the two slide grooves 6, and the bottom of the sliding seat 7 is fixedly connected to the top of the sealing cover 5. When the sliding seat 7 moves up and down along the slide groove 6, the sealing cover 5 can move synchronously to achieve the sealing or opening of the processing barrel 3. This design ensures the simplicity of operation and the closedness of the reaction environment.

[0025] The stirring structure includes a rotating shaft 8 rotatably connected to the bottom of the sealing cover 5, a motor 9 for driving the rotating shaft 8 to rotate is fixedly connected to the top of the sealing cover 5, a sieve plate 12 is rotatably provided at the bottom of the rotating shaft 8, a rotating shaft 2 15 is rotatably provided at the bottom of the sieve plate 12, a bevel gear 16 is fixedly sleeved on the rotating shaft 8, a bevel gear 2 17 is fixedly sleeved on the rotating shaft 2 15, a through opening is opened on the sieve plate 12, a rotating rod 18 is rotatably provided in the through opening, a bevel gear 3 19 is fixedly connected to the rotating rod 18, the bevel gear 3 19 is meshed with the bevel gear 16 and the bevel gear 2 17, a plurality of triangular scraping rods 10 are fixedly connected to the rotating shaft 8, and the triangular ends of the triangular scraping rods 10 are in contact with the vertical inner wall of the processing barrel 3; the setting of the bevel gear 3 19 makes the rotation directions of the rotating shaft 8 and the rotating shaft 2 15 opposite, so that there are two stirring directions in the processing barrel 3, which further improves the stirring efficiency.

[0026] A limiting member for limiting the position of the sieve plate 12 is arranged in the processing barrel 3 .

[0027] The limiting member includes a ring platform 11 provided in the processing barrel 3, the ring platform 11 corresponds to the sieve plate 12, a plurality of slots 13 are provided on the ring platform 11, and a plug rod 14 corresponding to the slots 13 is fixed to the bottom of the sieve plate 12. The function of the ring platform 11 is to serve as a support and positioning structure for the sieve plate 12; the plug rod 14 is accurately inserted into the slot 13, thereby achieving accurate positioning and stable fixation of the sieve plate 12. This design not only ensures the stability of the sieve plate 12 during the mixing process, but also makes the installation and removal of the sieve plate 12 simple and quick.

[0028] The triangular scraper bars 10 are respectively arranged above and below the screen plate 12 .

[0029] The sieve plate 12 and the vertical inner wall of the treatment barrel 3 slide vertically against each other. The close-fitting design ensures the stability of the sieve plate 12 during the lifting process, and also prevents solid particles from escaping from the edge of the sieve plate 12, ensuring the cleanliness and safety of the sewage treatment process.

[0030] The functional principle of the utility model can be explained through the following operation modes:

[0031] When using the device, first, the user needs to hold the sliding seat 7 with his hands and move it vertically upward, and then introduce the chemical sewage and the reactant into the treatment barrel 3. Then, loosen the grip of the sliding seat 7, so that the sealing cover 5 and the treatment barrel 3 are sealed together, ensuring that the chemical reaction is carried out in a closed environment.

[0032] At this time, the insertion rod 14 is inserted into the slot 13, which realizes the limit fixation of the sieve plate 12 to prevent it from moving during the stirring process. Next, the motor 9 is started, and the motor 9 drives the rotating shaft 8 to rotate, and the rotation of the rotating shaft 8 drives the triangular scraper 10 to rotate. The design of the triangular scraper 10 allows its rotation to improve the uniformity of stirring, ensure that the chemical sewage and the reactant react fully, and thus improve the treatment effect.

[0033] At the same time, the rotation of shaft 1 8 drives bevel gear 1 16 to rotate, bevel gear 1 16 drives bevel gear 3 19 and rotating rod 18 to rotate together, bevel gear 3 19 drives bevel gear 2 17 to rotate, bevel gear 2 17 drives shaft 2 15 to rotate, and shaft 2 15 drives the triangular scraper 10 thereon to rotate and stir; the rotation directions of shaft 1 8 and shaft 2 15 are opposite, so that the directions of rotation of the liquid above and below the sieve plate 12 are opposite, further improving the stirring efficiency.

[0034] After sufficient reaction, the treated water is discharged through the outlet pipe 4, completing the sewage treatment process. When the inside of the treatment barrel 3 needs to be cleaned, cleaning liquid is added to the treatment barrel 3. The triangular scraper rod 10 rotates under the action of the motor 9 to scrape off the residual substances on the inside of the treatment barrel 3, thereby realizing automatic cleaning of the treatment barrel 3.

[0035] Finally, after the sieve plate 12 is moved vertically upward, the large particles of debris on the sieve plate 12 can be uniformly collected for subsequent processing. Through the above steps, the device realizes the effective treatment and cleaning of chemical wastewater, and improves the wastewater treatment efficiency and quality.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
