Description

Technical Field

[0001] The utility model belongs to the field of 2,3-dichloropyridine production, in particular to wastewater treatment equipment, and relates to wastewater treatment equipment used for 2,3-dichloropyridine production. Background Art

[0002] 2,3-Dichloropyridine is a white powdery solid. 2,3-Dichloropyridine is a key intermediate in the synthesis of chlorantraniliprole. With the gradual promotion of chlorantraniliprole, the demand for 2,3-dichloropyridine will increase significantly. The synthesis method of 2,3-dichloropyridine has also attracted much attention. The synthesis process of 2,3-dichloropyridine will produce wastewater that is harmful to water bodies. The wastewater needs to be treated according to the standards, and 2,3-dichloropyridine production wastewater treatment equipment needs to be used.

[0003] A Chinese patent with publication number CN220034172U discloses a wastewater treatment device for the production of 2,3-difluoro-5-chloropyridine, comprising a treatment box, wherein two filter plates distributed left and right are installed inside the treatment box, and the two filter plates divide the treatment box into a sedimentation chamber and two decontamination chambers. The wastewater after the production of 2,3-difluoro-5-chloropyridine is first passed into the interior of the sedimentation chamber, and then a flocculant is added to the interior of the sedimentation chamber to precipitate impurities and large particles in the wastewater. At this time, the two filter plates filter the wastewater, and the filtered wastewater flows into the interior of the two decontamination chambers respectively through the two filter plates. When the two filter plates need to be cleaned, by starting two first water pumps and simultaneously starting two electric push rods, the two movable plates can be pushed to drive the two flushing pipes to move, so that the two flushing pipes are backwashed along the two filter plates, so as to achieve the effect of automatically cleaning the impurities in the filter plate mesh and avoid clogging of the filter plates.

[0004] When cleaning the filter plate in the above-mentioned comparative document, it is necessary to suspend the sedimentation treatment of the wastewater before cleaning the filter plate. The process wastes a lot of time and easily leads to the problem of low wastewater treatment efficiency. After the sediment is filtered, it enters the sewage pipe from the sedimentation chamber. The sediment is mixed with the water flow in the sewage pipe for cleaning the filter plate, and the solid and liquid are discharged together, which easily leads to the problem of clogging the sewage pipe.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0044] The application of one aspect of this embodiment is as follows: the cavity inside the box body 1 is divided into an upper sedimentation chamber and a lower sewage discharge chamber. After the wastewater in the sedimentation chamber is precipitated, sediment and water flow are generated. The sediment and water flow fall onto the baffle plate 3 and the filter plate 2. The baffle plate 3 can prevent the wastewater from flowing along the inner wall of the box body 1 to the discharge port 4, and prevent the wastewater from flowing out of the discharge port 4. The filter plate 2 can filter the sediment and water flow. The sediment is retained on the filter plate 2, and the water flows through the filter plate 2 and falls under the filter plate 2. The sediment retained on the filter plate 2 is easily blocked by the filter hole. The motor 2 602 is limited by the limit hole 5. The motor 2 602 can only move along the limit hole 5. The limit hole 5 is inclined. The vertical distances from the two sides of the limit hole 5 to the motor 1 601 are different. When the motor 2 602 slides in the limit hole 5, the distance from the motor 2 602 to the motor 1 601 changes. Therefore, when the motor 2 602 slides in the limit hole 5, it will drive the telescopic rod 603 to extend and retract.

[0045] By starting the motor 1 601 to drive the telescopic rod 603 to rotate, the telescopic rod 603 drives the motor 2 602 to rotate, and the motor 2 602 slides in the limit hole 5 after receiving the force of the telescopic rod 603, and the motor 2 602 applies a reverse force to the telescopic rod 603, and the telescopic rod 603 rotates and retracts at the same time, and the motor 2 602 slides in the limit hole 5 to drive the cleaning shaft 604 to slide along the top surface of the filter plate 2, and the cleaning shaft 604 can rub the top surface of the filter plate 2. Looking from the direction of the cleaning shaft 604 to the motor 2 602, the motor 2 602 is started counterclockwise, and the motor 2 602 drives the cleaning shaft 60 4 rotates counterclockwise, the outside of the cleaning shaft 604 is a brush structure, the sediment on the top surface of the filter plate 2 can be adsorbed on the cleaning shaft 604, the filter plate 2 can be cleaned to prevent the filter plate 2 from being blocked, the cleaning shaft 604 drives the sediment to reach the discharge port 4 and squeezes the sediment against the teeth of the sawtooth 301, when the motor 2 602 drives the cleaning shaft 604 to rotate counterclockwise, the teeth of the sawtooth 301 are inserted into the brush structure outside the cleaning shaft 604, the sawtooth 301 can remove the sediment adsorbed on the cleaning shaft 604, the sediment falls out from the discharge port 4, and the water flow and sediment can be classified and processed for discharge. It should be noted that all electrical equipment involved in this application can be powered by batteries or external power supplies.
