Description
Technical field
The utility model relates to the purification apparatus of a kind of water and other feed liquid, particularly a kind of sand filter that is used to handle the higher feed liquid of fermentation recirculated water and viscosity.
Background technology
In existing filtration art, filter, filter type are varied, but study carefully its essence is nothing but to make water or other feed liquid by various filtering layers, remove wherein impurity particle, organic substance etc., make it further reach clarification and purify, reach the requirement of recycle-water or create good conditions for next process.Sand filter is one of present widely used filter plant, and it is usually used in utilizing the filtering material of being adorned in it to remove the suspension that contains in the water to carrying out preliminary treatment early stage, and the cohesion tablet makes water outlet reach as clear as crystal.For fermentation recirculated water, its water yield is big, and is exposed to outdoorly, and various impurity, content of organics are very high, are directly used in the quality that other operation can have a strong impact on product, therefore need carry out preliminary treatment to it.Existing pretreated method is a lot, but cost is very high mostly, and is not suitable for big flow processing.It is all multifactor to take all factors into consideration water treatment effect, operating cost and environmental protection etc., handling fermentation recirculated water with sand filter is the normal water treatment mode that adopts, but the sand filter of prior art exists the water treatment amount few, the water treatment facilities filtering layer is few, the water treatment weak effect, and it is serious to leak the sand phenomenon, and backwash effect is poor, defectives such as media regeneration weak effect.
The utility model content
At the above-mentioned defective that exists in the prior art, the utility model provides a kind of new type sand filter, and its water treatment is effective, the water treatment amount is big, cost of water treatment is low, media regeneration is effective.
The utility model is achieved by the following technical solution: a kind of new type sand filter, comprise that the bottom has the cylindrical shell of discharge outlet, the corresponding discharge outlet of the bottom inside of cylindrical shell is provided with the domes that have osculum, be provided with the gradually little layer of sand of two-stage at least of grit size in the cylindrical shell from the bottom to top successively, the top of layer of sand is provided with the water inlet water-locator that communicates with water inlet pipe, bottom in the cylindrical shell is provided with the backwash and regeneration water-locator that communicates with the backwash pipeline, and the backwash drainpipe is located at cylindrical shell top and communicates with the pond.
The utility model is to carry out water distribution by the water inlet water-locator that is located at top, by the multistage layer of sand that is located in the cylindrical shell former water is filtered, and the water after the filtration is discharged through discharge outlet.The structure of filtering layer that layer of sand in the utility model adopts grit size from the bottom to top successively to reduce can effectively filter former water on the one hand, and water treatment is effective, can prevent effectively that on the other hand the less sand grains of granularity from spilling cylindrical shell.The effect that is located at the domes of cylindrical shell bottom in the utility model is draining and anti-leak-stopping sand.The osculum of water after the filtration on domes enters the space that is formed by domes and cylindrical shell bottom, discharges from discharge outlet, and in draining, domes have effectively stoped the sand grains in the cylindrical shell to be discharged with water, have prevented leakage sand.Backwash and regeneration water-locator in the utility model is used for the backwash and regeneration of filtrate, backwash liquor can enter in the cylindrical shell through the backwash and regeneration water-locator, from bottom to top layer of sand is carried out backwash, make its regeneration, backwash water can enter the pond by the drainpipe on cylindrical shell top, through the post precipitation reusable edible, reach the purpose of cleaner production.
Layer of sand in the utility model can be made up of multistage layer of sand, considers filter effect and water treatment amount, and it can be made of supporting layer that is positioned at the bottom and superposed level Four filter sand layer, and the grit size maximum of supporting layer plays support top filter sand layers at different levels.
For anti-leak-stopping sand, the backwash and regeneration water-locator in the utility model can be arranged on the supporting layer.During backwash, be positioned at the supporting layer of backwash and regeneration water-locator bottom owing to be not subjected to the influence of backwash current, thereby the layer of sand of bottom is relatively stable, can stop effectively during filtration that granularity less sand grains loss in upper strata enters outlet conduit, influences the normal operation of water pump.
Influence pump operation for further anti-leak-stopping sand enters outlet conduit, also the secondary leak-proof device can be set on outlet conduit, this leak-proof device can adopt y-type filter, and sand grains is trapped through y-type filter the time.
In order to improve backwash effect, the backwash and regeneration water-locator in the utility model can be connected with pressing vacant duct, and during backwash, backwash liquor enters the backwash and regeneration water-locator simultaneously with pressing sky, can effectively improve the backwash effect.
The utility model compared with the prior art, and is simple in structure, and it can effectively remove the suspended particulate in the fermentation recirculated water by novel water distribution mode that is provided with and the multiple filtration layer of sand of arranging by gradient, has improved the water treatment effect greatly; Leak-proof devices at different levels can effectively be prevented leak-stopping sand, both improved the stability and the filter effect of filter bed, have guaranteed the reliable running of water pump etc. again; Novel backwash regeneration can guarantee the treatment effect of sand filter, improves the period treatment amount of sand filter, and cost of water treatment is low, and the utility model filter process is simple, and is easy to operate, is fit to the purified treatment of big flow water and the higher feed liquid of other viscosity.
