Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of can onlinely sweep the self-cleaning sand filter of stream at above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this online stream automatically cleaning sand filter of sweeping, include cylindrical shell, be arranged on the water inlet pipe on cylindrical shell top, inlet valve, be positioned at the filter material layer at cylindrical shell middle part, be positioned at the captation and the delivery port of cylindrical shell bottom, it is characterized in that also including the eddy flow water knockout drum that can produce the rotary water current water outlet and can produce rotation and sweep and flow out tangentially sweeping of water and spread water pipe, the eddy flow water knockout drum is arranged in the top of cylindrical shell and with the water inlet pipe of cylindrical shell and is connected, tangentially sweep and spread water pipe and be arranged on filter material layer top, near the filter material layer upper surface.
Described water inlet eddy flow water knockout drum includes at least two distributive pipes that are radial arrangement, and the water inlet end of each distributive pipe all is communicated with the water inlet pipe of cylindrical shell, the water side of each distributive pipe all have same rotation towards apopore, thereby make water outlet form eddy flow.Certainly, water inlet eddy flow water knockout drum also can adopt other various prior aries, as long as its water outlet forms eddy flow.
Described tangentially sweeping spread water pipe ringwise, and is provided with at least two nozzles thereon, each nozzle all have same rotation towards apopore, thereby make water outlet form eddy flow.Certainly, tangentially sweep and spread water pipe and also can adopt other various prior aries, as long as its water outlet forms and tangentially sweeps stream.
Described tangentially sweeping spread water pipe and can be had independently tangentially to sweep and flow to water pipe, but for integrated, and it is tangentially swept and flows to water pipe and can be connected with the water inlet pipe of cylindrical shell through a booster pump.
In order more effectively to collect and discharge the trapped substance that concentrates on filter material layer conical surface central authorities, also can be provided with the sewage collecting cover at the central part of cylindrical shell, it is spread between water pipe and the water inlet rotary return device tangentially sweeping, and its outlet communicates with the sewage outlet pipe that recoils; In order to prevent when recoiling, filtrate to be taken out of, also can be provided with sand separator in the described sewage collecting cover.
Compared with prior art, the utility model substitutes traditional water inlet water knockout drum with water inlet eddy flow water knockout drum, and set up tangentially to sweep and spread water pipe, the online stream of tangentially sweeping intermittently, realize that thus the current in the filter rotate the filter cycle that prolongs filter material layer, do not influencing under the situation of filtering operation, cleaning filter material layer surface filtration passage, the discharging high-concentration sewage, the distribution of filter material layer in filter simultaneously becomes taper seat by disk, increased the filter area of filter material layer, prolongs filter cycle, reduce the backwash water consumption, improve the filter operating efficiency.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As Fig. 1～shown in Figure 3, this is online sweeps stream automatically cleaning sand filter and includes cylindrical shell 1, is arranged on water inlet pipe 11, the inlet valve 12 on cylindrical shell 1 top, the filter material layer 2 that is positioned at cylindrical shell 1 middle part, the captation 3 that is positioned at cylindrical shell 1 bottom and delivery port 13, eddy flow water knockout drum 4 and tangentially sweeps and spread water pipe 5, referring to Fig. 1;
Described eddy flow water knockout drum 4 can produce the rotary water current water outlet, be arranged in the top of cylindrical shell 1 and and be connected with the water inlet pipe 11 of cylindrical shell 1, this eddy flow water knockout drum 4 includes four distributive pipes 41 that are radial arrangement, the water inlet end of each distributive pipe 41 all is communicated with the water inlet pipe 11 of cylindrical shell 1, the water side of each distributive pipe 41 all have same rotation towards apopore 42, thereby make water outlet form eddy flow, referring to Fig. 1, Fig. 2;
Described tangentially sweeping spread water pipe 5 and can be produced rotation and sweep outflow water, be arranged on filter material layer 2 tops, near filter material layer 2 upper surfaces, this is tangentially swept and spreads water pipe 5 ringwise, and is provided with four nozzles 51 thereon, each nozzle 51 all have same rotation towards apopore 52, thereby make water outlet form eddy flow, and tangentially sweep and spread water pipe 5 and have independently tangentially to sweep and flow to water pipe 53, this is tangentially swept and flows to water pipe 53 and be connected with the water inlet pipe 11 of cylindrical shell 1 through a booster pump 6, referring to Fig. 1, Fig. 3;
Central part at cylindrical shell 1 also is provided with sewage collecting cover 7, and it is spread between water pipe 5 and the eddy flow water knockout drum 4 tangentially sweeping, and the outlet of sewage collecting cover 7 communicates with recoil sewage outlet pipe 8, also is provided with sand separator 9 in this sewage collecting cover 7, referring to Fig. 1.
During normal the operation, water to be filtered is from water inlet pipe 11, the inlet valve 12 of flowing through, after 4 distributions of eddy flow water knockout drum, tangentially enter in the cylindrical shell 1, and water to be filtered rotates in the same direction, the current of rotation drive the also rotation in the same direction of trapped substance of the upper surface of filter material layer 2, constantly be enriched in the middle of the stream of rotation, thereby recovered the most filtration channel of filter material layer 2 upper surfaces, under the effect of tangential current, the distribution of filter material layer 2 in cylindrical shell 1 becomes taper seat by disk simultaneously, increase the filter area of filter material layer 2, and then prolonged filter cycle; Water passes filter material layer 2 backs from top to bottom and gets the back from delivery port 13 outflows by captation 3 collection simultaneously.
For further recovering the filtration channel of filter material layer 2 upper surfaces, turn down inlet valve 12, after startup booster pump 6 draws water supercharging from water inlet pipe 11 side direction, flow to water pipe 53 and enter cylindrical shell 1 at a high speed through tangentially sweeping, form tangential current, the part filtrate that these tangential current drive filter material layer 2 tops rotates in the same direction, and the trapped substance on filter material layer 2 surfaces has been swept, be rotated classification by the quality weight, the lightweight trapped substance is concentrated on the rotary water current center.Open recoil sewage outlet pipe 8 this moment, with this strand sewage from sewage collecting cover 7, behind sand separator 9 parting sand filtrates, discharge from recoil sewage outlet pipe 8, thereby realize slowing down trapped substance and stop up filter material layer 2 upper surface filtration channels, increase the filter area of filter material layer 2, prolong the filter cycle of filter material layer 2.
