Description

Technical Field

[0001] The utility model relates to the technical field of EDI ultra-pure water equipment, in particular to EDI ultra-pure water equipment. Background Technique

[0002] The EDI ultra-pure water equipment is a device for extracting ultra-pure water. In the water quality treatment technology, the pretreatment process plays a role in maintaining the equipment. When using the EDI ultra-pure water system to produce pure water, the raw water must be pretreated because there are many impurities in the raw water. If it is discharged into the EDI ultra-pure water device without treatment, it will cause damage to the equipment and affect the water production quality. In the production of pure water, the EDI module and the membrane separation technology are combined. These two technologies also have corresponding requirements for the incoming water quality during the operation of the equipment. The membrane element has the characteristic of extremely small micropores. If there are many large-particle impurities in the water quality entering the reverse osmosis device, it will directly cause the membrane element to be blocked and affect the operation of the whole set of equipment. The EDI module belongs to the most core technology in the current ultra-pure water production device. It purifies the water quality by the way of electro-deionization. If the module is accumulated with pollutants, it will not only affect the normal operation of the ion exchange process, but also directly damage the EDI module. The EDI module is the most advanced technology in the current ultra-pure water production, so it is more expensive than other accessories. If the raw water is not pretreated, it will shorten the service life of the equipment and bring economic burden to users. During the filtration process, it is often necessary to filter the water in the equipment. The filter screen will accumulate a lot of impurities and the filter screen cannot be replaced. Therefore, an EDI ultra-pure water equipment is particularly needed.

The filter screen will accumulate a lot of impurities. If the filter screen is not cleaned frequently, it will affect the filtration quality. Ultraviolet rays cannot sterilize the water comprehensively. At the same time, there will be residues remaining on the inner wall of the equipment after filtration, and the residues need to be cleaned, otherwise the filtration quality will be affected, which will affect the quality of ultra-pure water.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution: an EDI ultra-pure water device, including a device housing 1, a water inlet pipe 2 is fixedly connected to the upper surface of the device housing 1, a filtering mechanism 3 is arranged on the inner surface of the device housing 1, and a cleaning mechanism 4 is arranged on the lower surface of the device housing 1;

[0021] The filtering mechanism 3 includes a multi-media filter 301, a rotating plate 302, a first card slot 303, a first activated carbon filter screen 304, a motor 305, a stirring column 306, an ultraviolet lamp 307, a guiding pipe 308, a filter housing 309, a second card slot 310, a second activated carbon filter screen 311, a filtering material 312, and a water intake pipe 313. The lower surface of the water inlet pipe 2 is fixedly connected to the multi-media filter 301. One side surface of the equipment housing 1 is provided with the rotating plate 302.

The inner surface of the second activated carbon filter screen 311 is provided with the filtering material 312. One side surface of the filter housing 309 is fixedly connected to the water intake pipe 313. Through the settings of the multi-media filter 301, the rotating plate 302, the first card slot 303, the first activated carbon filter screen 304, the motor 305, the stirring column 306, the ultraviolet lamp 307, the guiding pipe 308, the filter housing 309, the second card slot 310, the second activated carbon filter screen 311, the filtering material 312, and the water intake pipe 313, when in use, when it is necessary to filter the water inside the equipment housing 1, first, the water is injected into the multi-media filter 301 through the water inlet pipe 2 for primary filtration. Then, the water flows out of the multi-media filter 301 into the equipment housing 1, and the water inside the equipment housing 1 is secondarily filtered by the first activated carbon filter screen 304. Then, the water penetrates through the first activated carbon filter screen 304 to the bottom of the equipment housing 1. The motor 305 is started, and the motor 305 drives the stirring column 306 to stir the water. The ultraviolet lamp 307 thus uniformly sterilizes the stirred water. At the same time, the sterilized water flows through the guiding pipe 308 to the filter housing 309. Then, the water penetrates through the second activated carbon filter screen 311 on the second card slot 310 inside the filter housing 309, and the filtering material 312 inside the second activated carbon filter screen 311 thus filters the water for the third time. Thus, the filtered water flows out from the water intake pipe 313. When a lot of impurities accumulate on the first activated carbon filter screen 304, the rotating plate 302 is opened, and the first activated carbon filter screen 304 is removed from the first card slot 303, and a new first activated carbon filter screen 304 is replaced, so as to filter the water inside the equipment housing 1.

[0022] Furthermore, the cleaning mechanism 4 includes a chute 401, an electric brush 402, a high-pressure water pipe 403, a high-pressure nozzle 404, an annular pipe 405, a water pipe 406 and a high-pressure water pump 407. The inner surface of the equipment housing 1 is provided with the chute 401, and the inner side surface of the chute 401 is slidably connected with the electric brush 402. One side surface of the equipment housing 1 is fixedly connected with the high-pressure water pipe 403, and one side surface of the high-pressure water pipe 403 is fixedly connected with the high-pressure nozzle 404. An annular pipe 405 is installed on one side surface of the high-pressure water pipe 403, and one side surface of the annular pipe 405 is fixedly connected with the water pipe 406, and one side surface of the water pipe 406 is fixedly connected with the high-pressure water pump 407. Through the chute 401, the electric brush 402, the high-pressure water pipe 403, the high-pressure nozzle 404, the annular pipe 405, the water pipe 406 and the high-pressure water pump 407, when in use, when cleaning the inner wall of the equipment housing 1, first suck water into the high-pressure water pump 407, then the high-pressure water pump 407 guides the water into the water pipe 406, and then the water pipe 406 flows the water into the annular pipe 405. At the same time, the water in the annular pipe 405 flows to various places, and the annular pipe 405 guides the water to the high-pressure water pipe 403, and then the high-pressure nozzle 404 sprays the water inside the high-pressure water pipe 403 onto the inner wall of the equipment housing 1. At the same time, start the electric brush 402, and the electric brush 402 slides on the chute 401, so that the electric brush 402 brushes the inner wall of the equipment housing 1, thereby cleaning the inner wall of the equipment housing 1.

[0023] Furthermore, the rotating plate 302 and the first activated carbon filter screen 304 form a rotating structure, and the first activated carbon filter screen 304 is symmetrically arranged with respect to the central axis of the rotating plate 302. Through the setting of the first activated carbon filter screen 304, the water inlet pipe 2 can inject water into the multi-media filter 301 for the first filtration. Then the water flows out of the multi-media filter 301 into the interior of the equipment housing 1, and the first activated carbon filter screen 304 performs secondary filtration on the water inside the equipment housing 1. Then the water penetrates through the first activated carbon filter screen 304 to the bottom of the equipment housing 1.

[0024] Furthermore, the motor 305 and the stirring column 306 form a rotating structure, and the ultraviolet lamp 307 is symmetrically arranged with respect to the central axis of the motor 305. Through the setting of the stirring column 306, the motor 305 can drive the stirring column 306 to stir the water, and the ultraviolet lamp 307 can thus uniformly sterilize the stirred water.

[0025] Further, the second card slots 310 are equally spaced on the inner surface of the filter housing 309, and the second activated carbon filter meshes 311 are equally spaced on the inner surface of the filter housing 309. Through the arrangement of the second activated carbon filter meshes 311, the sterilized water flows through the guiding pipe 308 to the filter housing 309, and then the water penetrates the second activated carbon filter meshes 311 on the second card slots 310 inside the filter housing 309, and the filtering material 312 inside the second activated carbon filter meshes 311 thus filters the water three times, and then the filtered water flows out from the water intake pipe 313.

[0026] Further, the sliding groove 401 and the electric brush 402 form a sliding structure, and the electric brush 402 is symmetrically arranged with respect to the central axis of the annular pipe 405. Through the arrangement of the electric brush 402, the electric brush 402 slides on the sliding groove 401, so that the electric brush 402 brushes the inner wall of the equipment housing 1.

[0027] Further, the high-pressure water pipes 403 are equally spaced on one side surface of the annular pipe 405, and the high-pressure nozzles 404 are equally spaced on one side surface of the high-pressure water pipes 403. Through the arrangement of the high-pressure water pipes 403, water is first sucked into the high-pressure water pump 407, and the water is introduced into the flowing water pipe 406 through the high-pressure water pump 407, and then the flowing water pipe 406 allows the water to flow into the annular pipe 405. At the same time, the water in the annular pipe 405 flows to various places, and the annular pipe 405 guides the water to the high-pressure water pipes 403, and then the high-pressure nozzles 404 spray the water inside the high-pressure water pipes 403 onto the inner wall of the equipment housing 1.

[0028] Working principle: First, when in use and when it is necessary to filter the water inside the device housing 1, water is first injected into the multi-media filter 301 through the water inlet pipe 2 for the first filtration. Then the water flows out of the multi-media filter 301 into the device housing 1, and the water inside the device housing 1 is secondarily filtered by the first activated carbon filter screen 304. Then the water penetrates through the first activated carbon filter screen 304 to the bottom of the device housing 1. The motor 305 is started, and the motor 305 drives the stirring column 306 to stir the water, and the ultraviolet lamp 307 thus uniformly sterilizes the stirred water. At the same time, the sterilized water flows through the guiding pipe 308 to the filter housing 309. Then the water penetrates through the second activated carbon filter screen 311 on the second card slot 310 inside the filter housing 309, and the filtering material 312 inside the second activated carbon filter screen 311 thus conducts a third filtration on the water, so that the filtered water flows out from the water extraction pipe 313. When a lot of impurities accumulate on the first activated carbon filter screen 304, the rotating plate 302 is opened, and the first activated carbon filter screen 304 is removed from the first card slot 303, and a new first activated carbon filter screen 304 is replaced, so as to filter the water inside the device housing 1. When cleaning the inner wall of the device housing 1, water is first sucked into the high-pressure water pump 407, and the water is introduced into the flowing water pipe 406 through the high-pressure water pump 407. Then the flowing water pipe 406 makes the water flow into the annular pipe 405. At the same time, the water in the annular pipe 405 flows to various places, and the water in the annular pipe 405 is guided to the high-pressure water pipe 403. Then the high-pressure nozzle 404 sprays the water inside the high-pressure water pipe 403 on the inner wall of the device housing 1. At the same time, the electric brush 402 is started, and the electric brush 402 slides on the chute 401, so that the electric brush 402 scrubs the inner wall of the device housing 1, thus cleaning the inner wall of the device housing 1.
