Description

Technical Field

[0001] The utility model relates to the technical field of medical wastewater treatment, in particular to a novel high-efficiency and environmentally friendly medical wastewater treatment equipment. Background Art

[0002] Hospital sewage refers to sewage discharged from hospitals (general hospitals, specialized hospitals and other types of hospitals) into the natural environment or urban pipelines. Its water quality varies with the nature, scale and location of different hospitals. The amount of sewage discharged per bed per day is about 200-1000L. The main pollutants contained in hospital sewage are: pathogens (parasite eggs, pathogenic bacteria, viruses, etc.), organic matter, floating and suspended matter, radioactive pollutants, etc. Medical wastewater needs to be treated with wastewater treatment equipment before it can be discharged.

[0003] For example, a medical wastewater treatment equipment with the authorization announcement number "CN220715139U" has an S-shaped loop between the first filter chamber and the second filter chamber. When the water passes through the first filter chamber, the second filter chamber and the filter screen, the water is intercepted and filtered in multiple stages to ensure that the subsequent water treatment is faster. However, in this medical wastewater treatment equipment, solid impurities and floccules will be present in the waste collection box, but the wastewater will also flow into the waste collection box, which requires the operator to remove the solid impurities and floccules and then send the wastewater back to the wastewater treatment equipment, which reduces the working efficiency of the medical wastewater treatment equipment. At the same time, the medical wastewater treatment equipment uses a stirring rod to initially intercept solid impurities, but when the hospital's drainage pipe is connected to the water inlet pipe, the operator cannot remove the stirring rod for cleaning, which causes the water inlet pipe to be blocked, which also reduces the working efficiency of the medical wastewater treatment equipment. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that wastewater will also flow into the waste collection box, which requires the operator to take out the solid impurities and floccules and then send the wastewater back to the wastewater treatment equipment, which reduces the working efficiency of the medical wastewater treatment equipment and the initial interception of solid impurities by the stirring rod. However, when the hospital's drainage pipe is connected to the water inlet pipe, the operator cannot remove the stirring rod for cleaning, which causes the water inlet pipe to be blocked, which also reduces the working efficiency of the medical wastewater treatment equipment. A new type of high-efficiency and environmentally friendly medical wastewater treatment equipment is proposed.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] Preferably, the outer wall of the drum is rotatably connected to the box body via a bearing, and the surface of the cleaning roller is in contact with the inner wall of the box body.

[0009] Preferably, the impurity interception mechanism includes a second motor, the outer wall of the second motor is fixedly connected to the first shell through a bracket, the output shaft of the second motor is fixedly connected to the first bevel gear, the first bevel gear is meshed with two second bevel gears, the outer walls of the two second bevel gears are respectively fixedly connected to two cams, the outer wall of one of the cams is tightly pressed against the knocking block, and the outer wall of the knocking block is fixedly connected to the first filter.

[0010] Preferably, the outer walls of the two cams are rotatably connected to the first shell via a pin, and the outer wall of the first filter screen is slidably engaged with the water inlet.

[0011] Preferably, the inner wall of the box body is fixedly connected to the first partition, the outer wall of the first partition is fixedly connected to the second filter screen, the inner wall of the box body is fixedly connected to the second partition, and the outer wall of the second partition is fixedly connected to the third filter screen.

[0012] The utility model proposes a novel high-efficiency and environmentally friendly medical waste water treatment equipment, which has the beneficial effects that: through the cooperation of the box body and the impurity discharge mechanism, the first motor drives the worm to rotate, the worm drives the worm wheel to rotate, the worm wheel drives the drum to rotate, the drum drives the slider to move through the slide groove on the surface, and the slider drives the cleaning roller to move. Since the lower end of the cleaning roller is in close contact with the box body, the cleaning roller brings the solid impurities and flocs at the bottom of the box body to the first sliding door, and the operator opens the first sliding door to clean the inside of the box body. The above method can prevent the waste water in the box body from being discharged from the box body together with the solid impurities and flocs, thereby improving the working efficiency of the medical waste water treatment equipment.

[0013] Through the cooperation of the first shell and the impurity interception mechanism, the second motor drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, the second bevel gear drives the cam to rotate, the two cams knock on the knocking block in turn, and the knocking block drives the first filter to vibrate to prevent the first filter from being blocked. Through the above method, larger solid impurities and flocs can be intercepted by the first filter, and there is no need to wait until the discharge is completed before cleaning, which also improves the working efficiency of the medical waste water treatment equipment.
