Description

Technical Field

[0001] The utility model relates to the technical field of disinfectant preparation, in particular to a sterilization and filtering device for a disinfectant preparation machine. Background Art

[0002] Disinfectant is a liquid disinfectant, which is characterized by strong bactericidal ability and fast action speed. It is mainly used for disinfection work in various places and requirements to kill bacteria, fungi, viruses and other microorganisms. When preparing disinfectant, a disinfectant preparation machine can quickly prepare disinfectant by adding raw water and disinfectant powder into the machine body and mixing them in a certain proportion. In order to ensure the preparation quality of disinfectant, a sterilizing filter device is usually used to sterilize and filter the raw water. However, during use, some existing sterilizing filters for disinfectant preparation machines sterilize the raw water by setting a silver ion sterilizing layer on the guide plate in the device, and filter the raw water by setting a filter net in the device. However, since the guide plate is mostly fixedly installed inside the device, it is inconvenient to replace the silver ion sterilizing layer after it fails. At the same time, it is inconvenient to disassemble and clean the filter net, which is not conducive to use. Therefore, a sterilizing filter device for a disinfectant preparation machine is proposed.

[0028] When in use, raw water is injected into the interior of the treatment box 3 through the water inlet pipe 4, and in the process of flowing downward, the raw water will contact the silver ion sterilization layer 8 on the guide plate 7 to sterilize the raw water, and then the raw water will enter the interior of the installation frame 12 through the liquid collecting hopper 9, so as to be filtered through the filter screen 13, and finally the raw water after sterilization and filtration will be gathered on the inner bottom wall of the treatment box 3. At this time, the water pump 151 can be started by the external controller to transport the raw water to the interior of the disinfectant preparation machine body 2, so as to be used for the preparation of disinfectant. When the silver ion sterilization layer 8 on the guide plate 7 fails and needs to be replaced, the two first hand wheels 224 can be turned to drive the two rotating shafts 221 and the two driving bevel gears 222 to rotate, and then the two first threaded rods 19 can be driven to rotate through the two driven bevel gears 223, and the two first threaded rods 19 will drive the upper and lower first positioning rods 19 during the rotation.

When the filter screen 13 needs to be cleaned, the two second threaded rods 244 can be driven to rotate by twisting the two second hand wheels 245, so as to drive the two sliders 242 and the two second positioning blocks 243 to move back to back, so that the two second positioning blocks 243 are respectively moved out of the inside of the two second positioning grooves 23, thereby releasing the fixation between the mounting frame 12 and the processing box 3. At this time, the mounting frame 12 can be pulled out to the left from the inside of the processing box 3 by the handle 14, so as to disassemble the filter screen 13, thereby facilitating the cleaning operation of the filter screen 13.

[0029] In summary, the sterilization and filtering device for the disinfectant preparation machine drives the two rotating shafts 221 and the two driving bevel gears 222 to rotate by turning the two first hand wheels 224, and then drives the two first threaded rods 19 to rotate through the two driven bevel gears 223. The two first threaded rods 19 will drive the first positioning blocks 21 on the upper and lower sides to move relative to each other during the rotation, so that the four first positioning blocks 21 are respectively moved out from the inside of the four first positioning grooves 20, thereby releasing the fixation between the two mounting plates 6 and the processing box 3. At this time, the two mounting plates 6 can be respectively pulled out from the inside of the two through holes 5, so as to disassemble the guide plate 7, thereby facilitating the replacement of the silver ion sterilization layer 8 on the guide plate 7. Secondly, the two second threaded rods 244 are driven to rotate by turning the two second hand wheels 245, so as to drive the two sliders 242 The two second positioning blocks 243 are moved away from the inside of the two second positioning grooves 23, thereby releasing the fixation between the mounting frame 12 and the treatment box 3. At this time, the mounting frame 12 can be pulled out to the left from the inside of the treatment box 3 by the handle 14, so as to disassemble the filter screen 13, thereby facilitating the cleaning operation of the filter screen 13. This solves the problem that during use, the existing sterilization and filtration devices for some disinfectant preparation machines will sterilize the raw water by setting a silver ion sterilization layer on the guide plate in the device, and filter the raw water by setting a filter screen in the device. However, since the guide plate is mostly fixedly installed inside the device, it is inconvenient to replace the silver ion sterilization layer after it fails. At the same time, it is also inconvenient to disassemble and clean the filter screen, which is not conducive to use.
