Description

Technical Field

[0001] The utility model relates to the technical field of spraying, in particular to a spraying device for treating medical wastewater. Background Art

[0002] Medical wastewater contains a large number of pathogens, such as bacteria (such as Staphylococcus aureus, Escherichia coli, etc.), viruses (such as hepatitis virus, new coronavirus, etc.), fungi and parasite eggs. If these pathogens are discharged directly without effective treatment, they will cause serious pollution to the environment and threaten human health. For example, when medical wastewater containing pathogenic bacteria enters the water body, it may cause the spread of waterborne diseases and cause people who come into contact with contaminated water to be infected with intestinal diseases.

[0003] In the existing technology, when medical wastewater is treated, uneven spraying will occur. Uneven spraying will result in incomplete wastewater treatment. Wastewater in some areas may not be fully exposed to the treatment agents, resulting in residual harmful substances and substandard quality of the treated wastewater. This poses risks to environmental protection and subsequent wastewater discharge supervision. Uneven spraying may also lead to waste of agents. In areas with excessive spraying, excessive use of agents not only increases treatment costs, but may also cause other potential hazards to the environment. For example, excessive use of certain agents may have toxic effects on aquatic organisms. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the inventors have conducted in-depth research and completed the present utility model after paying a lot of creative work.

[0005] Specifically, the technical problem to be solved by the present invention is to provide a spraying device for medical wastewater treatment to solve the current technical problem of uneven spraying when treating medical wastewater.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A spray device for treating medical wastewater, comprising a housing, a top sealing plate fixedly connected to an upper edge of the housing, a liquid storage tank fixedly connected to an upper surface of the top sealing plate near the center, a spray chamber defined within the housing, a drive motor fixedly connected to a bottom of the spray chamber, a cleaning assembly fixedly connected to an output end of the drive motor near an edge, a screw fixedly connected to the output end of the drive motor, and a spray assembly slidably connected to an outer wall of the screw;

[0008] The spray assembly includes a liquid storage chamber that is slidably connected to the screw rod. Two sealing plates are fixedly connected to the liquid storage chamber near the upper and lower ends. A threaded hole is provided near the center of the sealing plate. The screw rod is rotatably connected inside the threaded hole. Spray pipes are fixedly connected to both sides of the liquid storage chamber. A plurality of nozzles are fixedly connected to the bottom of the spray pipe. The spray pipe is rotated by the drive motor. Rotating the nozzle can spray the spray liquid evenly and comprehensively to the treatment area to avoid dead corners of spraying.

[0009] As an improved technical solution, the upper end of the liquid storage chamber is fixedly connected to a lifting tube, the interior of the lifting tube is slidably connected to a guide tube, and the upper end of the guide tube is fixedly connected to the bottom of the top sealing plate.

[0010] As an improved technical solution, a plurality of liquid inlet holes are provided on the upper surface of the sealing plate near both sides.

[0011] As an improved technical solution, the cleaning assembly includes a connecting part fixedly connected to the drive motor, connecting tubes are fixedly connected on both sides of the connecting part, a connecting arm is slidably connected inside the connecting tube, and a scraper is vertically fixedly connected to the other end of the connecting arm.

[0012] As an improved technical solution, a sliding cavity is provided inside the connecting cylinder, an elastic member is fixedly connected to the bottom of the sliding cavity, and the other end of the elastic member is fixedly connected to the connecting arm.

[0013] As an improved technical solution, a sealing cover is fixedly connected to the bottom of the spray chamber near the center, and the driving motor is arranged inside the sealing cover.

[0014] After adopting the above technical solution, the beneficial effects of the utility model are:

[0015] 1. The utility model drives the motor to rotate, which drives the spray pipe to rotate, so that the nozzle can spray the spray liquid evenly and comprehensively to the treatment area, avoiding the occurrence of spray dead angles. At the same time, when the nozzle rotates, the spray liquid continuously contacts the medical wastewater at different angles and directions, increasing the contact time and frequency of the spray liquid and the wastewater. This allows the treatment agent in the spray liquid to more fully react chemically with the pollutants in the wastewater, thereby improving the treatment efficiency.

[0016] 2. The utility model drives the scraper to clean the inner wall of the spray chamber when the driving motor rotates. At the same time, due to the different accumulation time of dust on the inner wall of the spray chamber, the resistance encountered by the scraper is also different. The elastic part can play a buffering role, absorb these impact forces, reduce the instantaneous stress borne by the scraper and the connecting arm, thereby extending the service life of the scraper and the connecting arm.
