If stopping water purifying producing, only need rotating operation handle 13 that it is returned to close stance and get final product.
Three, by interior pressure mode back flushing filter core working order
Filter core will be held back some dirts in its outside surface when producing water purification by the external pressure mode, for anti-blocking right in the end, should in time carry out counterflush to filter core, only need this moment operation handle arm 13 is clockwise rotated, just the utility model can be placed by interior pressure mode and produce the working order that water purification removes the back flushing filter core; The moving plate 12 of ceramic cartridge concerns shown in figure seven with the position of stator 11 at this moment; Be a sidewalk for visually impaired people 12-J on the moving plate 12 (figure four), be communicated with the water inlet duct 11-A and the multichannel ceramic cartridge external pressure water outlet duct 11-D of the multichannel ceramic cartridge on the stator 11 (figure three) with its ditch shape structure; Another sidewalk for visually impaired people 12-H on the moving plate 12 is then with multichannel ceramic cartridge external pressure water inlet duct 11-B and multichannel ceramic cartridge water outlet duct 11-C on its ditch shape structure connection stator 11; Tap water was flowed through successively to filter by running water pipe 9 and was covered 1 water inlet duct 4 this moment, the water inlet duct 11-A of stator 11, the blind logical 12-H of moving plate 12 imports multichannel ceramic cartridge external pressure water outlet duct 11-D on the stator 11 with its ditch shape structure with tap water, enter in the cavity of filter core 3 through the water outlet duct 8 of filter core 3, by himself pressure, tap water is flowed and enters filter cylinder 2 to its outside surface by the filter core internal surface, then by the external pressure of the multichannel ceramic cartridge on the stator 11 water inlet duct 11-B, import the water outlet duct 11-C of multichannel ceramic cartridge by the sidewalk for visually impaired people 12-J of moving plate 12, and flow out by thrust-augmenting nozzle, meanwhile the dirt attached to the filter core outside surface is backwashed and outflow thereupon; Only needing rotating operation handle 13 to make it be returned to close stance when stopping to recoil gets final product.
By as can be known above-mentioned: present embodiment is for directly to be connected on running water pipe and family expenses refining plant that can recoil filter core at any time, and it is in normally off during use; After operation handle arm is rotated counterclockwise, just there is the water purification of producing by the external pressure mode to flow out, meanwhile not only the dirt in the tap water is retained in the filter core outside surface, also the dirt of filter core internal surface is washed away simultaneously; After operation handle arm turned clockwise, just there is the water purification of producing by interior pressure mode to flow out, meanwhile not only the dirt in the tap water is retained in the filter core internal surface, while is also washed away the dirt of filter core outside surface, that is to say that interior the pressure with the external pressure working order all has the function of cutting dirty and dirt removal, how do we obtain water purification so? here used the theory of " very slight dirt just can recoil totally with water seldom "; One day about 100-200 litre water purification of using in the kitchen, the dirt pettiness that is retained down, and degree of adhesion is very light, and just can be clean with the 5-10 premium on currency its recoil, and this 5-10 rises the formed dirt of water purification more less, just can recoil it completely up hill and dale with the 0.5-1 premium on currency.We stipulate following using priciple in view of the above:
1. produce water purification with the external pressure mode of operation, recoil with interior pressure mode of operation;
2. the cycle of recoiling is different and different according to various places water quality, recoils once after generally using 100-200 litre (about 20-40 basin) water purification;
3. mode recoils: when the first step goes recoil to produce 100-200 litre water purification with the external pressure mode of operation with the water purification of pressing mode of operation to produce in the 5-10 litre (about 1-2 basin) earlier, remain in the dirt on the filter core outside surface; Second step is with the water purification that 0.5-1 (about 2-4 cup) external pressure mode of operation produces, and go to recoil to remaining in dirt on the filter core internal surface when producing 5-10 litre water purification with interior pressure mode of operation, thereby the cleaning of assurance filter core as before.
The utility model can be applicable on commercial husky filter or the active carbon filtering device fully in order to the back flushing filtrate, and is different with the described duct type family expenses refining plant that recoils only on the structure of filter core; The filter material of household water filter filter core is cast into body, and the filter material of commercial sand filter is bulk cargos such as quartz sand, manganese sand; The cavity structure die cast of household water filter filter core, commercial sand filter then are as cavity with a pipeline that has an aproll device.
