Abstract
The utility model discloses a sand lifting and washing device which comprises a cylinder, wherein a water outlet and a water inlet are respectively formed in the upper part and the lower part of the cylinder; a corrugated sand washer is arranged on the top of the cylinder; a sand lifter is arranged at the bottom of the cylinder; the sand lifter is connected with a compressed air inlet pipe and is connected with the corrugated sand washer through a sand lifting conveying pipe outside the cylinder. According to the sand lifting washer, air sand lifting and hydraulic sand lifting are combined into a whole, so that an active sand filter is stable and high-efficiency in sand lifting and washing in the operating process; a corrugated sand washing sleeve is arranged inside the corrugated sand washer, dirty sand is lifted into the sand washer to form turbulent stirring through water flow of the corrugated sleeve, and the dirty sands are rubbed and collided, so that dirt attached to the sand surface drops, and the sands are fully cleaned through the corrugated sand washer and flow back into the filter.
Description
Technical field
The utility model belongs to field of Environment Protection, is specifically related to one and carries sand sand-washing device.
Background technology
Along with the pollution of expanding economy environment is also more and more serious, particularly outstanding to the pollution of water body, national requirements more large town sewage treatment plant and large enterprise's sewage disposal discharge standard need reach one-level A mark.Tradition is carried sand sand-washing device and is had following shortcoming: 1, traditional sand sand-washing device of carrying only provides source of the gas by air compressor machine, make the dirty sand of filter bottom be promoted to top sand-washing device by the sand extraction tube in equipment, because lifting process has certain altitude, making to put forward sand process, easily to occur carrying sand discontinuous unstable, causes dirty sand to can not get cleaning active sand filter water outlet timely not up to standard; 2, traditional sand-washing device cannot be completely thoroughly cleaned the dirt on sand surface, and not clean sand flows back to treatment effeciency and the treatment effect that filter interior reduced filter and causes water outlet not up to standard.
Also do not occur in the market that a kind of gas, water are carried sand jointly and with the sand-washing device of corrugated bushing, be used for better cleaning dirty sand and make filter keep higher disposal ability and treatment effect.
Summary of the invention
Goal of the invention: the purpose of this utility model is for the deficiencies in the prior art, provides one to carry sand sand-washing device.
Technical scheme: in order to reach foregoing invention object, the utility model is specifically achieved like this: one is carried sand sand-washing device, comprise cylindrical shell, it is characterized in that, cylindrical shell upper and lower is respectively equipped with delivery port and water inlet, and top is provided with ripple sand-washing device, and bottom is provided with carries sand device, the described sand device of carrying is connected with compressed air inlet pipe, and is connected with ripple sand-washing device by the sand carrier pipe of carrying outside cylindrical shell; Described ripple sand-washing device is directly connected with the washed-out sand drainpipe stretching to outside cylindrical shell.
Wherein, described water inlet is by carrying sand filling pipe and carrying sand carrier pipe and be connected outside cylindrical shell, and design can make water pressure pushing sand enter and carry sand carrier pipe like this, and is advanced into ripple sand-washing device on interior.
Wherein, be separately provided with sand distributor at the bottom of described inner barrel, make more convenient the entering of sand of cylinder body bottom carry sand device, sand distributor is preferably shaped as triangle, prismatic or taper.
Wherein, described ripple sand-washing device bottom is provided with ripple washed-out sand sleeve pipe, makes dirty sand abundant agitating friction when by sand-washing device, and sand surface dirt comes off more thorough.
Beneficial effect: the utility model is compared with conventional art, and tool has the following advantages:
1, air is put forward to sand and waterpower and carried sand and be combined as a whole, make active sand filter in running, carry sand washing sand stability and high efficiency more;
2, ripple sand-washing device inside is provided with ripple washed-out sand sleeve pipe, dirty sand is promoted to behind sand-washing device inside and forms eddy flow by corrugated bushing current and stir between dirty sand frictional impact mutually the dirt that is attached on sand surface is come off, and sand is flowing back to filter interior by the abundant afterwash of ripple sand-washing device.
Brief description of the drawings
Accompanying drawing is structural representation of the present utility model.
Detailed description of the invention
As shown in drawings, the disclosed sand sand-washing device of carrying of the utility model, comprise cylindrical shell 1, cylindrical shell 1 upper and lower is respectively equipped with delivery port 2 and water inlet 3, top is provided with ripple sand-washing device 4, bottom is provided with and carries sand device 5, described in carry sand device 5 and be connected with compressed air inlet pipe 6, and be connected with ripple sand-washing device 4 by the sand carrier pipe 7 of carrying outside cylindrical shell 1; Described water inlet 3 is by carrying sand filling pipe 8 and carrying sand carrier pipe 7 and be connected outside cylindrical shell 1; Described cylindrical shell 1 inner bottom is separately provided with prismatic sand distributor 9, makes more convenient the entering of sand of cylindrical shell 1 bottom carry sand device 5; Described ripple sand-washing device 4 bottoms are provided with ripple washed-out sand sleeve pipe, make dirty sand abundant agitating friction when by sand-washing device, and sand surface dirt comes off more thoroughly and ripple sand-washing device 4 is directly connected with the washed-out sand drainpipe 10 stretching to outside cylindrical shell 1.
In the time of specific works, constantly carry out when filtering, impurity in former water is also constantly accumulated and is trapped in filter material surface, and the dirty amount maximum of filter is the filtrate of bottom, by the sand of suspended solid pollutant, the passage forming by sand distributor 9 and the inclined plane of cylindrical shell 1, lower to carrying sand device 5, carried sand, 5 sands of collecting, deliver into and carry in sand carrier pipe 7 by the air in compressed air inlet pipe 6, carry water in sand filling pipe 8 by intake pressure and enter and carry in sand carrier pipe 7, enter the sand of carrying in sand carrier pipe 7 and jointly put on to ripple sand-washing device 4 by air, current; Contaminated sand acutely rubs with water and air in lifting process, in ripple sand-washing device 4, air separates with sand, water, sand is because gravity declines by the wavy channel of ripple sand-washing device 4, rinse water (part is filtered water outlet) flows in wavy channel from the bottom of ripple sand-washing device 4, sand is relative with rinse water to be contacted, sand is cleaned, clean sand is evenly distributed to cylindrical shell central authorities again, sewage clean sand is discharged from washed-out sand water outlet pipe 10 by drainage arrangement, and water body up to standard is discharged by delivery port 2.
