Description
Technical Field
The invention relates to a high-efficiency disinfection and sterilization hemodialysis water treatment device for blood, and belongs to the field of medical instruments.
Background
The water used for hemodialysis in hospitals has very high requirements on water quality, so the requirements on the process are very high, the process of hemodialysis water treatment equipment must be strict, and tap water needs to be firstly pressurized by a south pump to ensure that the water reaches enough pressure. The raw water enters a multi-medium filter capable of removing impurities, passes through an active carbon filter capable of removing residual chlorine and a water softener capable of reducing hardness. The raw water after the pretreatment can reach the secondary reverse osmosis host to further remove heavy metal ions, bacteria and the like. The peculiar smell is purified by an ultraviolet sterilizer from a purification water tank to a pure water pump to a disinfection device, and finally the water is filtered by a precise microporous filter to be discharged.
In the conventional multi-media filter, since raw water is directly filtered in the previous stage, filter paper is easily blocked in the multi-media filter, and the filter paper needs to be frequently replaced. The multi-media filter capable of being automatically replaced is usually realized through a pressure sensor and an air cylinder, after filter paper is blocked, the water pressure in the filter rises, and after the sensor detects that the pressure is too high, the air cylinder is controlled by a control system to pull out the filter paper and push in new filter paper. Although the filter paper can be automatically replaced in the mode, two problems exist, one is that if the filter paper is replaced externally, a gap exists between the filter paper frame and the container, water leakage is easy to occur, if the filter paper is replaced internally, the filter paper is always in the water, and partial impurities attached to the filter paper can enter the water again, so that the filter paper is blocked too fast; the other is that the electric control system has high price, troublesome operation and high failure rate, and once the system makes mistakes, a large amount of filter paper is wasted or the filtration is not thorough.

The working principle and the process are as follows:
when the filter cartridge is in work, raw water is disinfected at a high temperature of 121 ℃, then enters the filter cartridge from the water inlet pipe, falls from the opening after being filtered by the filter paper, and enters the next procedure for continuous filtration. Along with the impurity on the filter paper increases, filter paper filter effect variation, lead to cartridge filter internal pressure grow, water pressure makes the piston board rise, the lift cover passes through the magnet actuation with the piston board at a distance from the cartridge filter, the lift cover also rises along with the piston board, the rack also rises thereupon simultaneously, the rack drives gear revolve, pawl and ratchet card die this moment, the gear drives the collection axle and rotates, with the filter paper roll on the collection axle, filter paper slides in the cartridge filter bottom, and then make new filter paper get into filtration region, old filter paper shifts out filtration region. After the water pressure is stable, the piston plate stops rising, the gear stops rotating, and the filter paper stops sliding along the gear. The new filter paper filters the raw water, the water pressure in the filter cartridge gradually drops, the piston plate gradually falls and resets, the rack falls along with the piston plate, the ratchet wheel cannot be clamped by the pawl at the moment, and the paper collecting shaft cannot rotate. In the sliding process of the filter paper, because the blocking condition of the filter paper is not fixed, when new filter paper enters a filtering area, the filter paper stops moving as long as the water pressure is reduced, and the stepless replacement is realized, so that the utilization rate of the filter paper can be improved to the maximum extent, the cost is reduced, and the service life of the whole roll of filter paper is prolonged. The whole device realizes automatic filter paper replacement in a mechanical mode, does not need manpower and participation of an electric control system, and has the advantages of simple structure, reliable operation and convenient maintenance.
