The rotation of the spiral blade can effectively realize vertical stirring of the pharmaceutical wastewater in the treatment box, and the rotation of the stirring rod can effectively realize horizontal stirring of the pharmaceutical wastewater in the treatment box, so that the pharmaceutical wastewater is in full contact reaction with the added flocculation agent, and the flocculation precipitation effect is improved; the baffle plate is arranged, so that splashing of the pharmaceutical wastewater during stirring can be reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical intermediate wastewater treatment, in particular to a precipitation device for wastewater treatment. Background Technique

[0002] Ribavirin, chemically named 1-β-D-ribofuranosyl-1H-1,2,4-triazole-3-carboxamide, is an organic compound mainly used as an antiviral drug. Ribavirin intermediates are actually some chemical raw materials or chemical products used in the synthesis process of ribavirin. Such chemical products do not require a drug production license and can be produced in ordinary chemical factories. As long as they reach a certain level, they can be used in the synthesis of ribavirin drugs. During the chemical production process of ribavirin intermediates, wastewater will be generated due to various reactions. These wastewaters contain a large amount of macromolecular organic matter. If directly discharged into the subsequent sewage treatment tank, it will cause a greater burden on the sewage treatment tank. Therefore, these wastewaters need to be pretreated before being discharged into the sewage treatment tank for treatment and purification.

[0003] Patent No. CN211004721U discloses a wastewater treatment device during the synthesis reaction of pharmaceutical intermediates, including a treatment tank. Two isolation bases are respectively arranged on both sides of the bottom of the treatment tank. The interior of the treatment tank is sequentially divided into a head buffer chamber, a flocculation precipitation chamber and a tail buffer chamber from front to back. A flocculation reagent box is arranged above the flocculation precipitation chamber. Three droppers are fixedly installed at the bottom of the front end of the flocculation reagent box. One first precipitation inclined plate and one second precipitation inclined plate are respectively fixedly installed on both sides of the bottom of the flocculation precipitation chamber. The wastewater treatment device during the synthesis reaction of pharmaceutical intermediates of the utility model flocculates and precipitates the first-stage chemical wastewater containing a large amount of macromolecular organic matter by setting a treatment tank and connecting it to the synthesis reaction process of pharmaceutical intermediates, and finally discharges it regularly through the sewage outlet, so that the treated wastewater can be directly discharged into the sewage treatment tank for treatment.

[0004] However, the above wastewater treatment device during the synthesis reaction of pharmaceutical intermediates still has the following deficiencies:

[0005] Although the above device can put flocculation reagents into the flocculation precipitation chamber through the droppers, since the positions of the droppers are fixed and the dropping range is limited, the flocculation reagents cannot contact and react well with the pharmaceutical wastewater, reducing the flocculation effect. In view of this, we propose a precipitation device for wastewater treatment. Content of the Utility Model

[0006] The purpose of the present utility model is to overcome the deficiencies of the prior art, meet the actual needs, and provide a sedimentation device for wastewater treatment, so as to solve the technical problem that although the above device can input flocculating agents into the flocculation sedimentation cavity through a dropper, due to the fixed position of the dropper and the limited dosing range, the flocculating agents cannot contact and react well with the pharmaceutical wastewater, reducing the flocculation effect.

Among them, a slot for the rotating shaft 305 to penetrate is opened in the middle of the baffle 303, and the rotating shaft 305 is fixedly connected with the spiral blade 306 and the stirring rod 307 respectively. In the present utility model, the small motor 304 effectively drives the rotation of the rotating shaft 305, thereby driving the rotation of the spiral blade 306 and the stirring rod 307 on the surface of the rotating shaft 305. The rotation of the spiral blade 306 can effectively realize the vertical stirring of the pharmaceutical wastewater inside the treatment tank 1, and the rotation of the stirring rod 307 can effectively realize the horizontal stirring of the pharmaceutical wastewater inside the treatment tank 1, so that the pharmaceutical wastewater is fully contacted and reacted with the added flocculant, improving the flocculation precipitation effect. The setting of the baffle 303 can reduce the splashing of the pharmaceutical wastewater during stirring.

[0029] It should be noted that the adjusting mechanism 2 includes a support 201. A group of supports 201 are symmetrically fixed on both sides of the top of the treatment tank 1. A multi-stage hydraulic cylinder 202 is fitted inside the support 201. The movable end of the multi-stage hydraulic cylinder 202 is connected to a limit frame 203. A lead screw 204 is installed inside the limit frame 203. The end of the lead screw 204 is connected to a driving motor 205. A positioning frame 206 is attached to the outside of the driving motor 205. A threaded block 207 is sleeved on the outside of the lead screw 204. Among them, the threaded block 207 is fixedly connected to the support 301, and the threaded block 207 is fitted and engaged inside the limit frame 203. In the present utility model, the driving motor 205 effectively drives the rotation of the lead screw 204, thereby driving the horizontal movement of the threaded block 207 sleeved on the surface of the lead screw 204, realizing the adjustment of the horizontal position of the auxiliary mechanism 3 at the lower end of the threaded block 207, facilitating the full stirring of the auxiliary mechanism 3 inside the treatment tank 1.

[0031] Working principle: Pour the pharmaceutical wastewater into the filter rack 404. The filter screen 407 at the bottom inside the filter rack 404 preliminarily filters the pharmaceutical wastewater, reducing the large particle impurities in the pharmaceutical wastewater and optimizing the flocculability of the pharmaceutical wastewater.

Then, add a flocculation agent into the treatment tank 1. Drive the rotating shaft 305 to rotate through the small motor 304, thereby driving the spiral blade 306 and the stirring rod 307 on the surface of the rotating shaft 305 to rotate. The rotation of the spiral blade 306 can realize the vertical stirring of the pharmaceutical wastewater inside the treatment tank 1, and the rotation of the stirring rod 307 can realize the horizontal stirring of the pharmaceutical wastewater inside the treatment tank 1, enabling the pharmaceutical wastewater to fully contact and react with the added flocculation agent.
