DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0025] Referring to Figures 1-4 , the medical wastewater treatment device comprises:

[0027] The feed pipe 2 is used to pass the medical wastewater into the processing tank 1, the dosing pipe 7 is used to pass the flocculating agent into the processing tank 1, and the discharge pipe 3 is used to discharge the treated wastewater.

[0028] The stirring assembly is connected to the processing tank 1 and has a working end sealingly penetrating into the inside of the processing tank 1.

[0029] The stirring assembly comprises a stirring motor 4 installed on the processing tank 1 and having an output end coaxially fixedly connected with a stirring shaft 5, and the stirring shaft 5 has an end away from the stirring motor 4 sealingly penetrating into the inside of the processing tank 1 and coaxially fixedly connected with a stirring blade 6.

[0030] The stirring motor 4 works, and its output end drives the stirring shaft 5 to rotate, the stirring shaft 5 drives the stirring blade 6 to rotate, and the medical wastewater and the flocculating agent in the processing tank 1 are stirred and mixed, so that the treatment effect of the wastewater is improved.

[0031] The stirring motor 4 is a motor with reversible output, and the output direction of the stirring blade 6 is arranged along the axial direction of the stirring shaft 5.

[0032] When the output end of the stirring motor 4 rotates forward, the stirring blade 6 rotates forward, and the wastewater near the stirring blade 6 is pushed to flow upward. When the output end of the stirring motor 4 rotates reversely, the stirring blade 6 rotates reversely, and the wastewater near the stirring blade 6 is pushed to flow downward. The stirring effect of the wastewater and the flocculating agent in the treatment tank 1 is improved, and power is provided for subsequent treatment.

[0033] The treatment mechanism includes a plurality of circulating pipes 8, the top ends of the circulating pipes 8 are communicated with the top of the treatment tank 1, and the bottom ends are communicated with the bottom of the treatment tank 1. The bottom of the circulating pipe 8 is communicated with a filtering bin 9, and the top is communicated with a purification bin 13.

The inner bottom of the purification bin 13 is fixedly connected with a glass plate 14, and the inner top is installed with an ultraviolet lamp 15.

[0034] When the water in the treatment tank 1 flows, part of the wastewater flows through the circulating pipe 8. When the wastewater passes through the filtering bin 9, it is filtered by the filter screen 11, and the intercepted waste residue falls into the inner bottom of the filtering bin 9, so that after the medical wastewater treatment is completed, the waste residue is discharged through the residue discharge pipe 12. When the wastewater passes through the purification bin 13, the ultraviolet lamp 15 works, and the ultraviolet light emitted by the ultraviolet lamp 15 transmits through the glass plate 14 and irradiates on the wastewater, forming an ultraviolet light irradiation treatment effect on the wastewater, and improving the treatment effect of the medical wastewater.

[0035] The inner top of the filtering bin 9 is fixedly connected with a rotating frame 10, the filter screen 11 is rotatably connected to the bottom of the rotating frame 10, and a torsional spring is fixedly connected between the filter screen 11 and the rotating frame 10.

[0037] When the stirring blade 6 rotates forward and pushes the wastewater near it to flow upward, the wastewater flows from the top end to the bottom end of the circulating pipe 8, and under the pushing action of the water flow, the filter screen 11 rotates and abuts against the side wall of the filtering bin 9, overcoming the elastic force of the torsional spring. When the stirring blade 6 rotates reversely and pushes the wastewater near it to flow downward, the wastewater flows from the bottom end to the top end of the circulating pipe 8, and finally the filter screen 11 rotates reversely and abuts against the other side wall of the filtering bin 9. Thus, while maintaining the filtering effect of the filter screen 11, the wastewater can be driven bidirectionally and alternately for multiple times, so that the backwashing effect of the filter screen 11 can be achieved, the service life of the filter screen 11 is improved, and the work burden of the staff replacing the filter screen 11 is reduced.

[0039] The purification cavity is in a flat rectangular shape, so as to reduce the depth of the wastewater and facilitate the comprehensive irradiation treatment of the wastewater in the purification cavity by the ultraviolet lamp 15.

[0040] A plurality of guide plates 16 are fixedly connected to the top and bottom of the treatment tank 1, the guide plates 16 are in an arc shape, the plurality of guide plates 16 correspond to the two ends of the plurality of circulating pipes 8 one by one, and the center of the arc is located on one side close to the middle of the treatment tank 1, and the two ends of the circulating pipe 8 are located between the corresponding two guide plates 16.

[0041] In the water flow driven by the stirring blade 6, the water flow is splashed to the circulating pipe 8 along the guide plate 16, so as to improve the flow power of the water flow entering the circulating pipe 8, facilitate the rotation of the filter screen 11 to overcome the elastic force of the torsion spring, and improve the stability of the filter screen 11 during work.

[0042] Valves 17 are installed on the feeding pipe 2, the discharging pipe 3, the dosing pipe 7 and the slag discharge pipe 12.
