Description
Technical field
The utility model belongs to swimming pool water treatment facilities manufacturing technology field, particularly a kind of vertical sand filter.
Background technology
Swimming pool water must could utilize after treatment once more.Strainer is an imperative equipment during the swimming pool water circulation is handled, and by the filtrate effect in the strainer, removes suspension in anhydrating, organic matter etc., thereby reduces the turbidity of water, makes the water after the filtration reach the purpose of utilizing once more.Present swimming pool strainer comprises cylindrical shell, and cylindrical shell is provided with water inlet, delivery port, outlet valve, loads filtrate in the cylindrical shell, and is after swimming pool water enters cylindrical shell, through the effect of filtrate, external by the outlet pipe expelling tube then.But, the existing strainer difficulty of catchmenting.Therefore, be necessary existing swimming pool is improved with the structure of sand filter and innovates, to overcome the above-mentioned defective that exists.
Summary of the invention
Of the present utility model disclose a kind of catchment simple and easy, install, change the vertical sand filter of swimming pool convenient, that intensity is big and the life-span is long.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted: the vertical sand filter of a kind of swimming pool, comprise cylindrical shell, outlet valve is established at the cylindrical shell top, cylinder lateral wall has water inlet, delivery port, load filtrate in the cylindrical shell, the part that catchments is established in the filtrate below, and the part that catchments is threaded by filter stick and forms.
The vertical sand filter of described swimming pool is respectively established the filtrate bed course in the filtrate and the part that catchments, catchment part and the cylindrical shell at the end.
The vertical sand filter of described swimming pool, filtrate adopt quartzy extra large sand, and particle diameter is 0.5-0.7mm.
The vertical sand filter of described swimming pool, the uniform slit of filter stick, filter stick is made by the ABS engineering plastics.
Swimming pool is a swimming pool water circulation cleaning equipment with vertical sand filter, is widely used in the circulating water treatment in all kinds of swimming pools, leisure pond.Swimming pool of the present utility model with the part that catchments of vertical sand filter catchment evenly, resistance is little, its installation, change convenient; The filter stick that constitutes the part that catchments adopts the ABS engineering plastics to make, and intensity is big, the life-span is long.Filtrate of the present utility model adopts quartzy extra large sand, has that abrasion resistance is good, an advantage of uniform particles, easy cleaning.Delivery turbidity after These characteristics has guaranteed to filter is low, water quality is excellent and good stability, has prolonged the backwashing period of sand filter simultaneously, has reduced maintenance rate and cost.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As shown in Figure 1, cylindrical shell 1 is supported by leg, and automatic air valve 4, hanger 2 are established in cylindrical shell 1 top, and cylinder lateral wall offers water inlet 6, delivery port 7 and setting pressure instrument board 3, and water inlet 6, delivery port 7 feed water inlet pipe, outlet pipe respectively.In addition, cylindrical shell is also established top manhole 5 and side manhole 8.Inner barrel is loaded filtrate bed course 9 from the bottom up successively, the part 10 that catchments, filtrate bed course 21, filtrate 22, and the part 10 that catchments is made of many groups filter stick 16, and every group of filter stick adopts the screw thread serial connection to form, and every group of filter stick is spirally connected with outlet pipe 17 again, as shown in Figure 2.
Shown in Fig. 3,4,5, filter stick 16 is circular, vertically evenly outwards protrudes 4 reinforcing ribs 19, and filter stick 16 32 slits 18 that vertically also evenly distribute make the water after the filtration infiltrate filter stick.Water after the filtration infiltrates the slit of filter stick, is collected by the part that catchments, and under the effect of water pump, flows out outside cylindrical shell by outlet pipe.
The filtrate of sand filter adopts high grade quartz sea sand, and particle diameter is 0.5～0.7mm, and nonuniformity coefficient is less than 1.4; Filtrate bed course 9 is a high grade quartz sea sand, and particle diameter is 2～8mm; Filtrate bed course 11 is a cobble, and particle diameter is 8～20mm.
Be illustrated in figure 6 as valve arrangement figure of the present utility model.
Sand filter is as follows from the concrete operations that dead ship condition switches to the normal filtration state:
1, closes all valves, open circulating water pump;
2, open filtered water inlet valve 11;
3, open and filter out water valve 14, and control valve, sand filter enters the normal filtration state.
4, filter end, close and filter out water valve 14;
5, close filtered water inlet valve 11;
6, close circulating water pump.
In operating process, enter in the sand filter for avoiding air, should open filtered water inlet valve 11 earlier, open again and filter out water valve 14; During parking, close earlier and filter out water valve 14, after close filtered water inlet valve 11, close circulating water pump at last.
Along with the accumulation of normal filtration time, the contamination thing on sand filter filter bed surface increases gradually, and filtration resistance increases, and influences filter effect, and need carry out backwash this moment.
Sand filter can not directly switch to the backwash state from the filtration state, and the switching concrete operations are as follows:
1, closes and filter out water valve 14;
2, close filtered water inlet valve 11;
3, close circulating water pump;
4, treat that equipment shut down 2-3 minute after, restart circulating water pump;
5, open backwash water intaking valve 13;
6, open sewage backwash valve 12, regulate sewage backwash valve 12, the control back washing strength;
7, backwashing time continues 5～7 minutes, and intensity is between 12～15L/Sm2;
8, on the blow-off pipe in the backwash observation port current be cleaning, transparent after, close sewage backwash valve 12;
9, close backwash water intaking valve 13, backwash finishes.
After the backwash, the part dirt also accumulates on filtering layer and the pipeline, does not enter swimming pool for making dirt, should just wash when backwash finishes, and just can switch to the normal filtration state thereafter.It is as follows to switch to the concrete operations of just washing state from the backwash state:
1, closes sewage backwash valve 12;
2, close backwash water intaking valve 13;
3, open filtered water inlet valve 11;
4, open and just wash blowoff valve 15;
5, continue 1～2 minute;
6, close and just wash blowoff valve 15;
7, close filtered water inlet valve 11, just washing end.
After just washing end, can not switch off the pump, be directly switch to the filtration state.
