Description

Technical Field

[0001] The utility model relates to the technical field of hospital sewage treatment, in particular to a hospital sewage treatment device with a disinfection function. Background Art

[0002] In addition to general domestic sewage, hospital sewage also contains chemical substances, radioactive wastewater and pathogens. Therefore, it must be treated before it can be discharged, especially sewage discharged from infectious disease wards such as hepatitis, which must be disinfected before it can be discharged. Hospitals without centralized sewage treatment equipment must disinfect infectious feces separately to render them harmless. Commonly used disinfectants include chlorine dioxide, bleaching powder, liquid chlorine, sodium hypochlorite, and ozone. Sewage containing radioactive isotopes should be treated according to isotope treatment requirements. During the treatment of hospital sewage, the precipitated sludge contains a large number of bacteria, viruses and parasite eggs, and must be disinfected (usually disinfected with slaked lime) or high-temperature composting before it can be used as fertilizer.

[0003] Announcement No. CN218910055U discloses a hospital sewage treatment device with a disinfection function, including sewage treatment equipment, a sewage discharge device and a stirring device. The sewage discharge device is fixedly installed on the outer wall of one end of the sewage treatment equipment, and the stirring device is fixedly installed inside the other end of the sewage treatment equipment. The sewage discharge device uses the power of mud and dirt discharge to reduce the size of the discharged mud and dirt, and the stirring device is used to expand the contact area between the disinfectant and the sewage. The utility model can utilize the water flow generated by the rotation of the blades to achieve full contact between the disinfectant and the internal sewage, increase the contact area between the two, speed up the disinfection speed, and improve the disinfection effect, but the above device has disadvantages.

[0004] When the disinfectant is put into the sewage treatment equipment, the disinfectant is condensed as a whole and enters the sewage in the sewage treatment equipment. As a result, after the disinfectant enters the sewage, a stirring device is required to stir the disinfectant in the sewage for a long time to break up the disinfectant that has been condensed in the sewage, which reduces the efficiency of the disinfectant in disinfecting the sewage. The disinfectant cannot be quickly broken up and mixed with the sewage. For this reason, we propose a hospital sewage treatment device with a disinfection function to solve the above problems.

[0023] See also Figure 1-6 The utility model provides an embodiment: a hospital sewage treatment device with a disinfection function, comprising a sewage treatment device 1,

[0024] A control panel 2 is provided on the front side of the sewage treatment equipment 1, a treatment tank 3 is provided in the sewage treatment equipment 1, a first water pipe 4 is provided at the left end of the sewage treatment equipment 1, the first water pipe 4 is connected with the treatment tank 3, a motor 5 is installed at the upper end of the sewage treatment equipment 1, a stirrer 6 is rotatably installed in the treatment tank 3, the stirrer 6 is fixedly connected to the output shaft of the motor 5, a dispersion component is installed on the upper end of the stirrer 6, an injection ring 13 is installed in the treatment tank 3, the injection ring 13 is sleeved on the stirrer 6, a second water pipe 14 is fixedly installed at the rear end of the injection ring 13, and the rear end of the second water pipe 14 is inserted in the sewage treatment equipment 1. The device injects disinfectant into the treatment tank 3 through the injection ring 13 and the second water pipe 14, and then the motor 5 drives the stirrer 6 to rotate while driving the dispersion component to break up the disinfectant flowing into the treatment tank 3, so as to facilitate the rapid mixing of the disinfectant and sewage.

[0025] Further, the dispersion assembly includes a sleeve 7, which is rotatably mounted on the agitator 6, a first bevel gear 8 is fixedly mounted on the upper end of the agitator 6, a second bevel gear 9 is mounted in the upper end of the sewage treatment equipment 1, a third bevel gear 10 is mounted on the upper end of the sleeve 7, the first bevel gear 8, the second bevel gear 9 and the third bevel gear 10 are meshed with each other, a turntable 11 is fixedly mounted on the lower end of the sleeve 7, a plurality of groups of grooves 12 are annularly arranged on the upper end of the turntable 11, the turntable 11 is located below the injection ring 13, and the two groups of fans on the agitator 6 The blades are fixedly connected to the stirrer 6 and the lower end of the turntable 11 respectively, and the fan blades at the lower end of the turntable 11 are sleeved on the stirrer 6. The rotation of the stirrer 6 drives the sleeve 7 and the turntable 11 to rotate through the first bevel gear 8, the second bevel gear 9 and the third bevel gear 10, and the disinfectant is broken up and mixed into the sewage through the rotation of the turntable 11. The fan blades at the lower end of the turntable 11 and the fan blades on the stirrer 6 rotate separately, thereby generating two sets of stirring vortices when stirring the sewage of the sewage treatment equipment 1, further accelerating the mixing efficiency of the sewage and the disinfectant.

[0026] Furthermore, two groups of ring blocks 15 are fixedly installed in the sleeve 7, and the two groups of ring blocks 15 are movably inserted on the outer wall of the agitator 6. Multiple groups of balls 16 are annularly installed on the inner walls of the two groups of ring blocks 15, and the multiple groups of balls 16 slide on the outer wall of the agitator 6. When the sleeve 7 with this structure rotates on the agitator 6, it slides on the outer wall of the agitator 6 through the two groups of ring blocks 15 and the multiple groups of balls 16, thereby increasing the smoothness of the rotation of the sleeve 7 on the agitator 6 and avoiding jamming of the sleeve 7 when rotating on the agitator 6.

[0027] Furthermore, two groups of ultraviolet lamps 17 are fixedly installed on the upper side of the treatment tank 3, and the two groups of ultraviolet lamps 17 are located on the left and right sides of the agitator 6. This structure uses the two groups of ultraviolet lamps 17 to disinfect the sewage with ultraviolet light, and the disinfectant and the two groups of ultraviolet lamps 17 are used to disinfect the sewage synchronously, thereby improving the disinfection speed of the sewage.

[0028] Furthermore, two groups of protective plates 18 are fixedly installed on the upper inner wall of the treatment tank 3, and the two groups of protective plates 18 are located on the left and right sides of the agitator 6.

[0029] Furthermore, the two groups of protective plates 18 are transparent as a whole, and the two groups of ultraviolet lamps 17 are located inside the two groups of protective plates 18. This structure allows the two groups of ultraviolet lamps 17 to irradiate the sewage through the two groups of protective plates 18 because the two groups of protective plates 18 are transparent, and will not hinder the disinfection effect of the two groups of ultraviolet lamps 17 on the sewage.

[0030] Working principle: When disinfecting sewage, Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, sewage is first injected into the sewage treatment equipment 1 through the first water pipe 4, and then the motor 5 drives the stirrer 6 to rotate in the treatment tank 3 to stir the sewage. The stirrer 6 drives the first bevel gear 8 to rotate while rotating. The first bevel gear 8 rotates to drive the second bevel gear 9 and the third bevel gear 10 to rotate. The third bevel gear 10 rotates to drive the sleeve 7 and the turntable 11 on the stirrer 6. Then the disinfectant is injected into the treatment tank 3 through the injection ring 13 and the second water pipe 14, and the disinfectant drips on the turntable 11. When the turntable 11 rotates, the disinfectant is thrown out in the multiple groups of grooves 12, and the turntable 11 drives The moving fan blades rotate, and the agitator 6 drives the fan blades at the lower end to rotate. When the disinfectant drips onto the turntable 11, the turntable 11 rotates to break up the disinfectant, so that the disinfectant thrown out by the turntable 11 falls into the sewage in the treatment tank 3, so that the fan blades at the lower end of the turntable 11 and the agitator 6 rotate synchronously, and the two groups of rotation speeds and directions are different, so that the two groups of fan blades rotate in opposite directions, generating two groups of relatively stirring vortices, the agitator 6 and the fan blades on the turntable 11 rotate to quickly mix the sewage and the disinfectant, and the two groups of ultraviolet lamps 17 irradiate and disinfect the sewage in the treatment tank 3. The above is the entire working principle of the utility model.
