Abstract
The utility model discloses a low-pressure micro-resistance quartz sand filter, which has a square box body structure and mainly comprises a water inlet chamber, a quartz sand filtering layer and a rinsing chamber, wherein the quartz sand filtering layer is vertically arranged in the box body and provided with water seal plates at two sides; the water inlet chamber and the rinsing chamber are arranged at two sides of the quartz sand filtering layer in a split way; a backwashing water pipe is arranged at the bottom of the quartz sand filtering layer and a cover plate is arranged above the quartz sand filtering layer; a pollutant discharge chamber is arranged at the upper part of the cover plate; and a drain groove is arranged in the pollutant discharge chamber. The low-pressure micro-resistance quartz sand filter works in the manner that the filter water flow is horizontal and the backwashing water is vertical from the bottom up. The water inlet chamber of the low-pressure micro-resistance quartz sand filter can be provided with low pressure, therefore, the treatment amount is increased, the filtering efficiency is improved, the water is saved and the utilization rate of the backwashing water is enhanced; and the filtering layer is arranged vertically and the filtered water flows horizontally, so that the resistance of the filtered water comes from quartz sand filter material, a nylon screen and a reinforced iron pore plate, and the resistance is small, therefore, the filtering efficiency can be improved.
Description
Technical field
The utility model belongs to the water treatment facilities technical field, is specifically related to a kind of quartz sand filtration device.
Background technology
The quartz sand filtration device is mainly used in the suspension of removing in the water.This equipment cooperates with other water treatment facilities, is widely used in all kinds of engineering of water treatment such as water supply purification, recirculating water purification sewage disposal.Filtering ponds are the indispensable facilities of water treatment.In water treatment and environment-friendly engineering, various filter tanks are arranged, as rapid filter, valveless filtering pool, cylinder suction strainer pond etc.The import of these filter tank water and outlet level height difference are between 1.5-2.5 rice, and the filtering velocity of being filtered is between 15-20m/h, and this just limits treating capacity.Press the filter course resistance and distinguish, large, medium and small resistance filter tank is arranged, all these resistances all influence the efficient of filtration.Quartz sand filtration requires filter course thickness to reach 750mm, and the drainage direction in existing filter tank all is vertical form, and filtering surface all is a horizontal positioned, exists the drawback that equipment volume is big, occupation of land is many.Filter course will have backwash, and traditional backwash all is a countercurrent backwashing, has quite a few water to run away in vain before backwash, and in the backwash process, some water by filter course, is not run away with other backwash mode yet, causes the waste of water resource.
Summary of the invention
The purpose of this utility model provides a kind of little resistance quartz sand filtration of low pressure device that improves filter efficiency, reduces equipment volume.The technical solution adopted in the utility model is: the little resistance quartz sand filtration of low pressure device is a square box structure, mainly constitute by intake chamber, quartz sand filtration layer, clean water chamber, the quartz sand filtration layer is perpendicular to be put in casing, and there is water seal board on the two sides, and intake chamber and clean water chamber are separated in the filter course both sides; In the bottom of quartz sand filtration layer the backwash water pipe is arranged, cover plate is arranged above, the blowdown chamber is arranged at cover plate top, in the blowdown chamber rhone is arranged.
The working method of the little resistance quartz sand filtration of low pressure device is: filtered water stream is a level, and backwash water is vertical from bottom to top backwash.During filtration, water inlet pipe is opened, and introduces former water to sealing low pressure intake chamber, and this intake chamber can bear the 1-12M water column pressure, closes backwash pipe valve and cover plate, fetch boiling water shrouding and water outlet pipe valve, and water enters into clean water chamber by the vertically passing filtering layer.
During backwash, close into that the water pipe valve stops into water, close water seal board simultaneously, open lid and pull, open the backwash pipe valve.Under a certain amount of water yield and backwash rate, body refuse is rinsed, and enters into rhone.After finishing, stop backwashing water, close cover plate, fetch boiling water shrouding and water intaking valve begin filtration work again.
The utlity model has following advantage:
1, taking up space is about 65% of general filtering ponds, because filtering layer is vertical placement, and the corresponding increase of filter space, the ineffective occupation space is less.
2, intake chamber can have low pressure (1-12M water column), and this has just increased treating capacity, has improved filter efficiency.
3, backwashing water has not a particle of white running away, as long as the backwash water valve is opened, is exactly directly flushing.The backwashing water process be not only the thick filtering layer of 750mm, but that vertical filtering layer has is how high, how high water just flushing is, improves the backwash water utilization rate.
4, filtration resistance is exactly a filtering layer, and general does not have supporting layer, do not have the resistance of supporting layer about 0.55M.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 filters the schematic diagram of state and backwash state for the utility model.
The specific embodiment
Embodiment adopts steel plate or concrete for making to become square box, in the middle of the box house intake chamber 1 is arranged, and is connected to water inlet pipe 2 in the intake chamber 1.Intake chamber 1 two sides is the perpendicular quartz sand filtration layer of putting 3, is two water purifying chamber 4 in twice filter course 3 outsides, and scenery with hills and waters pipe 5 is arranged in the water purifying chamber 4.Backwash water pipe 6 is arranged at quartz sand filtration layer 3 bottom, and cover plate 7 is arranged above, and top is blowdown chamber 8, because it is bigger to seethe needed space at filtering layer top silt particle during backwash, so blowdown chamber 8 is widened laterally, rhone 9 arranged in that blowdown is indoor, the body refuse in-line arrangement tank of going out during backwash 9 flows away.In quartz sand filtration layer 3 both sides movably water seal board 10 is arranged.
Because filtering layer is vertical placement, drainage horizontal flow mistake places the iron orifice plate of 40 order double-layer nylon nets and reinforcing in the both sides of filtering layer, the resistance that makes drainage is exactly a quartz sand filter media itself, does not have big or middle resistance, just the nylon wire and the orifice plate of sand, resistance is small, so can improve filter efficiency.
The left side of Fig. 2 is that equipment filters working state schematic representation, and the lid among the figure above the filtering layer 3 is pulled 7 lids down, and the water seal board 10 of filtering layer 3 both sides is an open mode, and former water flows into water purifying chamber 4 by the intake chamber 1 of central authorities through filtering layer 3.The right side is the backwash view, cover plate 7 upwards opens, and filtering layer 3 both sides water seal boards 10 are closed, and backwashing water upwards washes away filter course 3 by the backwash water pipe 6 of filtering layer 3 bottoms, the water that has certain pressure upwards seethes quartz sand to enter blowdown chamber 8, and the body refuse that rises is taken away with water through rhone 9.
