The gravity type valveless filter comprises a water inflow distribution box, a tank body, a water draining groove and various types of pipelines. The various types of pipelines comprises a compulsory flushing water pipe, a siphon auxiliary pipe, a siphon pipe series, a water cleaning pipe, a water inlet pipe and a water outlet pipe. The siphon pipe series comprises a siphon rising pipe and a siphon dropping pipe. The interior of the tank body is divided into a water cleaning region, a filtering region and a water gathering region. The water cleaning pipe is a channel between the water cleaning region and the water gathering region. The filtering region and the water gathering region are provided with multi-hole water distribution plates, and a drainage pipe and a water outlet are arranged in the tank body. The gravity type valveless filter is simple in structure, and filtering all can be carried out automatically without valve control, so that attending of a worker is not needed, and the cost is saved. Due to the fact that a flow stabilizing plate is arranged, water distribution of back washing water is even. The section of the top portion of the water outlet is ladder-shaped, so that the water discharging speed is accelerated, and efficiency is improved.
Description
Technical field
The utility model relates to the filter in cooling tower, says more specifically a kind of gravity type valveless water filter device.
Background technology

The specific embodiment
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing in the present embodiment, the technical scheme in the utility model embodiment is carried out clear, complete description.
as Fig. 1, shown in Figure 2, the utility model discloses a kind of gravity type valveless water filter device, comprise into water distributor box 2, tank body 1, rhone 4 and pipelines, water inlet distributor box 2 is arranged in tank body 1 top, rhone 4 is arranged in tank body 1 outside and is close to tank body 1, pipelines comprises forces wash tub pipe 5, auxiliary siphon tube 7, siphon piping 6, clear water pipe 18, water inlet pipe 11 and drainpipe 20, siphon piping 6 comprises siphon tedge 12, siphon down-comer 13, siphon tedge 12 and auxiliary siphon tube 7 stretch into tank body 1 inside, water inlet pipe 11 communicates with siphon tedge 12, tank body 1 inside is divided into clear water zone 16, filtering area 10 and gathering ground 15, clear water pipe 18 is the passage between clear water zone 16 and gathering ground 15, filtering area 10 is provided with porous water distributing plate 9 with gathering ground 15, tank body 1 inside is provided with drainage tube 17 and delivery port 3.Be provided with stabilier 8 between clear water zone 16 and filtering area 10.Auxiliary siphon tube 7 bottoms are provided with the siphon destructive bucket mouth of pipe 14.Siphon piping 6 tops are provided with inverted u-shaped pipe 19, force wash tub pipe 5 to connect siphon pipings 6 and inverted u-shaped pipe 19 tops.The cross section at drainage tube 17 tops is trapezoidal.
During work, former water enters the valveless water filter device from water inlet pipe 11 under Action of Gravity Field or under pressure-acting, then enters filtering area 10 by stabilier 8, filtering area 10 inside are provided with filter course, enter gathering ground 15 by filter course, this moment is owing to existing stabilier 8, so the backwashing water even water distribution again.The turbidity such as suspension in former water are trapped and are adsorbed in the surface and filter material layer of filter material layer, and the water that enters gathering ground 15 is the clear water after filtering.Clear water before filter with filter after under two liquid level potential difference effects or under former effect of water pressure, 15 enter clear water zone 16 from bottom to top along being communicated with clear water pipe 18 from the gathering ground, overflow into again the drainage tube 17 at top from clear water zone 16, flow to outlet pipe along drainage tube 17 by delivery port 3 and flow out the valveless water filter device with gravity current, because drainage tube 17 top cross-section are trapezoidal, so greatly accelerated water speed.Along with continuing of filtering carries out, the suspension equal turbidity matter of holding back in filter material layer and adsorbing increases gradually, turbid matter also penetrates successively filter course and enters gathering ground 15 and clear water zone 16, the resistance of media filtration also increases gradually simultaneously, the rate of filtration also reduces gradually, the liquid level of former water in siphon tedge 12 also rises gradually, when reaching the highest water surface, when namely allowing resistance maximum, if continue to filter product water, after filter, the turbidity of water is with defective, and also just at this moment, the valveless water filter device enters backwash process immediately automatically.
former water constantly enters siphon tedge 12 from water inlet pipe 11, upper orifice place at auxiliary siphon tube 7, enter auxiliary siphon tube 7 and fall along this pipe, pass through to force wash tub pipe 5 in dropping process, and take away and manage interior air, to connect siphon piping 6 and inverted u-shaped pipe 19 tops and force wash tub pipe 5, like this, just aspirated siphon piping 6, air in the top of inverted u-shaped pipe 19 and siphon down-comer 13, because the lower nozzle of siphon down-comer 13 is lived the mouth of pipe by water seal in drain water seal, so form gradually negative pressure in inverted u-shaped pipe 19 tops and siphon down-comer 13, and vacuum increases gradually, former water at the liquid level of siphon tedge 12 from " before backwash, the highest water surface in pipe " continue to rise rapidly, and cross inverted u-shaped pipe 19 tops, fall along siphon down-comer 13, so backwash has begun, clear water from top to bottom enters gathering ground 15 from clear water zone 16 along clear water pipe 18, again from the gathering ground 15 by filtering area 10 filtrate that recoils from bottom to top, make filtering area 10 be in expansion, filtrate rubs mutually, collision, the dirts such as suspension that are trapped and are adsorbed in filter course pass through filtering area 10 with current, enter siphon piping 6, along siphon tedge 12, siphon down-comer 13 also discharges by rhone 4.In backwash process, the waters surface in clear water zone 16 descend rapidly, and the clear water of another chamber that is separated by with one just enters indoor in backwash, participates in backwash, to guarantee enough washing times.When the water surface in clear water zone 16 was down to the siphon destructive bucket mouth of pipe 14, air entered the top of inverted u-shaped pipe 19 and siphon piping 6 from the siphon destructive bucket mouth of pipe 14, so siphon is destroyed, and the backwashing water cutout in siphon piping 6, backwash finishes.Simultaneously, the filtrate that is in the filter course of swelling state falls, and former water still enters filtering area 10, so begun again the filtration of one-period.
