Abstract
The utility model relates to a medium-speed filter for removing granular impurity suspended substances and solid substances in water in order to offer industrial water and domestic water meeting different uses. The medium-speed filter comprises a filtering tank provided with a water inlet, a water outlet, a washing outlet, a backwashing inlet, and a backwashing outlet; each inlet or outlet has the own opening and closing valve; and a double-layer filter material is installed in the filtering tank, wherein the upper layer is anthracite particle; and the lower layer is quartz sand particle. The medium-speed filter is mainly used for removing granular impurity suspended substances and solid substances in water; and the medium-speed filter has better filtering effect than that of the existing water filter, is easier to clean, and can be completely cleaned.
Description
Technical field
The utility model relates to a kind of middling speed filter, is used for removing water particulate contamination suspension, solids, so that water for industrial use and the domestic water that meets various different purposes to be provided.
Background technology
The filter effect of water filter is mainly by the decision of the quality of its filtrate, and filter material layer needs to clean in operation after a period of time, if clean thoroughly clean then can influence the later operation of filter material layer.Filter material layer is generally by just washing and backwash, and the choose reasonable of filtrate and arrange and will help to clean that therefore, the filtrate of filter is its most key part.
The utility model content
The technical problems to be solved in the utility model is: provide that a kind of this filter not only filter effect is better than the better middling speed filter of existing water filter filter effect, it is also more easy, thorough, clean to clean.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of middling speed filter, be used for removing water particulate contamination suspension, solids, so that water for industrial use and the domestic water that meets various different purposes to be provided, it includes the filtration tank body, filtering tank body is provided with water inlet, delivery port, just washes discharge outlet and backwash water inlet, backwash discharge outlet, each mouthful all has switching valve separately, in filtering tank body, be provided with double-layer filter material, the upper strata is the anthracite stratum granulosum, and lower floor is the quartz sand particle layer.
Described filtration tank body be provided with have the compressed air inlet that opens and closes valve and with the corresponding exhaust outlet in compressed air inlet.When carrying out backwash, can open intake valve and realize air water mixing backwash, to guarantee the completeness of backwash.
The floor height of described anthracite stratum granulosum is 1000～1200mm, and grain diameter is 3～4mm; The floor height of described quartz sand particle layer is 900～1100mm, and grain diameter is 0.6～1.2mm.
The double-layer filter material that anthracite particle and quartz sand particle are formed can guarantee effluent quality and maintain higher water velocity.Anthracite weight ratio quartz sand is light, big, the low weight anthracite of particle is on the upper strata, the big quartz sand of the small and dense degree of particle is in lower floor, filtering material particle is the distribution of " up big and down small " on the whole, can guarantee that like this filtrate has high retaining power, can guarantee the hold back effect of filtrate simultaneously fine suspension; And most suspended substances will be held back by the anthracite particle of big particle diameter, and the remaining short grained suspension of fraction will be held back by quartz sand, thereby the cycle of operation will be extended; Moreover this layout type of filtrate can make that when filtrate is carried out backwash the quartz sand particle layer of bottom is first by backwash, and then is backwash anthracite stratum granulosum, can prevent that like this bulky grain suspension from stopping up filtrate, guarantees the completeness of backwash.
The beneficial effects of the utility model are: this middling speed filter is mainly used in removes particulate contamination suspension, solids in the water, and filter effect is better than existing water filter, and easier cleaning, cleans more thorough, cleaner.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. filter tank body, 2. water inlet, 3. delivery port is 4. just being washed discharge outlet, 5. backwash water inlet, 6. backwash discharge outlet, 7. compressed air inlet.
The specific embodiment
Middling speed filter as shown in Figure 1, be mainly used in and remove particulate contamination suspension, solids in the water, so that water for industrial use and the domestic water that meets various different purposes to be provided, it includes and filters tank body 1, filter tank body 1 and be provided with water inlet 2, delivery port 3, just wash discharge outlet 4, backwash water inlet 5 and backwash discharge outlet 6, each mouthful all has switching valve separately, is provided with double-layer filter material in filtering tank body 1, the upper strata is the anthracite stratum granulosum, and lower floor is the quartz sand particle layer.
The floor height of anthracite stratum granulosum is 1000～1200mm, and grain diameter is 3～4mm; The floor height of quartz sand particle layer is 900～1100mm, and grain diameter is 0.6～1.2mm.
Filter locate to be provided with on the tank body 1 have the compressed air inlet 7 that opens and closes valve and with compressed air inlet 7 corresponding exhaust outlets.
The middling speed filter belongs to pressure filter, and former water relies on pressure access arrangement inside, and absorption is held back through filtrate, reaches the purpose of removing suspension.Anthracite weight ratio quartz sand is light, big, the low weight anthracite of particle is on the upper strata, the big quartz sand of the small and dense degree of particle is in lower floor, filtering material particle is the distribution of " up big and down small " on the whole, can guarantee that like this filtrate has high retaining power, can guarantee the hold back effect of filtrate simultaneously fine suspension; And most suspended substances will be held back by the anthracite particle of big particle diameter, and the remaining short grained suspension of fraction will be held back by quartz sand, thereby the cycle of operation will be extended.This middling speed filter is mainly used in removes particulate contamination suspension, solids in the water, and filter effect is better than existing water filter, and easier cleaning, cleans more thorough, cleaner.
