Referring to fig. 1-7, the present invention provides a technical solution: a continuous flowing sand filtering device comprises a filtering tank 1, wherein the upper part of the filtering tank 1 is cylindrical, the lower part of the filtering tank is conical, quartz sand used for filtering impurities in sewage is arranged in the filtering tank 1, the quartz sand can filter the sewage, a sand lifting pipe 2 is vertically arranged in the middle of the filtering tank 1 and provides a moving channel for the quartz sand, a sand washer 3 used for separating the quartz sand and flocculates is installed at the upper end of the sand lifting pipe 2, a conical sand separator 4 is arranged on the side wall of the sand lifting pipe 2 so as to be beneficial to the continuous downward flowing of the quartz sand, an air lifting pump 5 is fixedly connected with the lower end of the filtering tank 1 and is positioned under the sand lifting pipe 2, a water distributor 6 is arranged in the filtering tank 1 and is positioned above the sand separator 4, the outer end of the water distributor 6 is connected with a water inlet pipe 7, a water pump 701 is connected on the side wall of the water inlet pipe 7 in series, a water outlet pipe 8 used for discharging filtered water is arranged on the upper side in the filtering tank 1, the sand washer 3 is connected with a drain pipe 10 for discharging sand-washing sewage.
When filtering sewage, in order to wash quartz sand in succession, specifically speaking, sand washer 3 is including washing sand box 301, washes sand box 301 fixed mounting at the top of filter tank 1, carry the inside that the upper end of sand pipe 2 extends to washing sand box 301, wash the below of sand box 301 and be located to carry and open around sand pipe 2 and have ripple chamber 302, ripple chamber 302 is continuous S-shaped shakeout passageway, makes quartz sand can the striking swing at the in-process of whereabouts, more does benefit to the flocculate of separation and breaks away from quartz sand, wash sand box 301 upper end and be equipped with the blast pipe 303 that is used for outside exhaust air for the air that exhaust air lift pump 5 bloated, wash sand box 301 and blow off pipe 10 intercommunication, quartz sand density is bigger for sewage, after discharging from carrying sand pipe 2 top, can drop to ripple chamber 302 along with the air current from the discharge quartz sand of blast pipe 303, later fall back, because the whole water flow direction in the filter tank 1 is upward, and the corrugated cavity 302 is communicated up and down, upward water flow also exists in the corrugated cavity 302, and the water flow enters the sand washing tank 301 and is discharged through the sewage discharge pipe 10 after impacting and washing the falling quartz sand.
In order to reduce the loss of the quartz sand, the upper end of the corrugated cavity 302 is higher than the bottom of the sand washing box 301, the quartz sand lifted to the inside of the sand washing box 301 by the sand lifting pipe 2 will fall back downwards after being concentrated at the upper end of the corrugated cavity 302 due to the large self weight, and finally fall back to the inside of the filter tank 1.
In order to enable the sewage distribution to be more uniform, specifically, the water distributor 6 is horizontally distributed in the filtering tank 1 in a spiral shape, a plurality of water holes 601 are uniformly distributed below the water distributor 6, the water holes 601 are distributed below the water distributor 6, and quartz sand falling from the upper side can be effectively prevented from entering the inside of the water distributor 6 from the water holes 601 to cause blockage.
In order to facilitate the dosing treatment of sewage, for example, the flocculation capacity of suspended particles in the sewage is increased, a dosing device 9 is connected in series between the water distributor 6 and the water inlet pipe 7, the dosing device 9 comprises a through pipe 901, a water channel 902 is formed inside the through pipe 901, a medicine pipe 903 is arranged inside the water channel 902, the outer end of the medicine pipe 903 is inserted into a medicine tank containing medicine liquid outside, and the medicine tank can convey the medicine liquid into the water channel 902 through a conveying pump (not shown in the figure).
In addition, the chemicals can be added by utilizing the power of water flow, specifically, one side of the water channel 902 close to the water distributor 6 is a conical water outlet, and the chemical outlet of the chemical tube 903 is located at the conical water outlet, as shown in fig. 6, when sewage flows into the conical water outlet, the water flow becomes relatively rapid due to the fact that the conical water outlet is narrow, negative pressure is formed at the conical water outlet according to bernoulli equation, then the chemicals in the chemical tank can be pumped into the sewage through the chemical tube 903, the chemicals are automatically added into the sewage through the flowing of the sewage, the faster the flow speed of the sewage, the higher the negative pressure is, the more the chemicals are sucked, and the chemicals are favorably added to the sewage.
As shown in fig. 6, in order to realize the uniform mixing of the liquid medicine and the sewage, specifically, a uniformly mixing device 11 is connected in series between the medicine adding device 9 and the water distributor 6, a blade 12 is fixedly installed on the inside of the uniformly mixing device 11, and after the liquid medicine and the sewage are mixed and flow into the inside of the uniformly mixing device 11, the liquid medicine and the sewage are impacted on the blade 12 through the liquid medicine and the sewage, so that the liquid medicine and the sewage can be uniformly mixed, the liquid medicine and the sewage can be fully reacted, and the sewage treatment effect can be improved through flocculation.
The working principle is as follows: when the water distributor is used, the water pump 701 is started, so that sewage enters the water distributor 6 through the water inlet pipe 7, the sewage uniformly flows into the filtering tank 1 from the inside of the water holes 601, the quartz sand in the filtering tank 1 filters the sewage at the moment, the filtered sewage flows upwards and finally flows out through the water outlet pipe 8;
meanwhile, the air lift pump 5 is started, so that the air lift pump 5 injects air into the sand lifting pipe 2, partial quartz sand and water at the bottom of the filter tank 1 are lifted upwards from the inside of the sand lifting pipe 2 to the inside of the sand washing box 301, the quartz sand falls downwards into the inside of the filter tank 1 from the inside of the corrugated cavity 302 in the inside of the sand washing box 301, and the water flows upwards (in the direction of an arrow shown in fig. 2) in the inside of the corrugated cavity 302, so that the separation of the quartz sand from impurities in the sewage, such as flocculate, suspended particles and the like is realized (the quartz sand moves downwards, the suspended particles flow upwards along with the water flow), the suspended particles are discharged through the sewage discharge pipe 10, the quartz sand returns to the inside of the filter pipe 1 again, and the purification of the whole sewage and the cleaning cycle of the sand are realized.
