Abstract
The utility model provides a sand filter for uninterruptedly producing water. The sand filter comprises a pressure-bearing container, a material filtering layer, a supporting part, a water collecting chamber and a water outlet pipe, the pressure-bearing container consists of an elliptical head and a barrel, the supporting part supports the material filtering layer, an inner barrel extending axially is arranged between the supporting part and the upper head in the pressure-bearing container, a water distribution plate is arranged in the upper head, the pressure-bearing container is divided into a central water inlet chamber, a peripheral water inlet chamber, a corresponding central filtering chamber and a corresponding peripheral filtering chamber by the water distribution plate and the inner barrel, an individual water inlet pipe and an individual water inlet valve are arranged in each of the central water inlet chamber and the peripheral water inlet chamber, and an individual blowdown pipe and an individual blowdown valve are arranged in each of the central filtering chamber and the peripheral filtering chamber.
Description
Technical field
The utility model relates to a kind of filter, is specifically related to a kind of sand filter.
Background technology
Sand filtration is with natural siliceous sand, manganese sand and the anthracite water filtration treatment process process as filtrate; Mainly be big molecular solid particle and the colloid in the trap water, be usually used in after clarification (deposition) is handled to water treatment or the advanced treating of sewage after two stage treatment.
In use; Because filter material layer is constantly held back the impurity in the water, ever-increasing impurity can stop up the filtration channel in the filter material layer, because of its effluent characteristics descends and loss of flood peak increase; Need independent backwash equipment, prolong the service life of filter.Filtration and backwash process hocket, and have reduced operating efficiency, have increased the initial cost and the operating cost of equipment.
Summary of the invention
The technical problem that the utility model will solve provides a kind of sand filter of uninterrupted product water.
In order to solve the problems of the technologies described above, the technical scheme of the utility model is:
A kind of sand filter; The support component, collecting chamber and the outlet pipe that comprise the pressure resistant vessel that constitutes by ellipse head and cylindrical shell, filter material layer, support filter material layer; In the pressure resistant vessel; Be provided with an axially extended inner core between support component and the upper cover; Upper cover is built-in with water distributing plate, and water distributing plate and inner core are divided into center intake chamber and periphery intake chamber and corresponding filter chamber, center and periphery filter chamber, center intake chamber and periphery intake chamber with pressure resistant vessel and are respectively equipped with independent water inlet pipe and water intaking valve, and filter chamber, center and periphery filter chamber are respectively equipped with independent blow-off pipe and blowoff valve.
During use, when needing the filtrate of filter chamber, backwash center, the water intaking valve of closing center's intake chamber water inlet pipe is opened the blowoff valve of filter chamber, center blow-off pipe simultaneously, the filtrate of the filter chamber, pressure backwash center through water in the collecting chamber; During the filtrate of backwash periphery filter chamber, close the water intaking valve of periphery filter chamber water inlet pipe, open the blowoff valve of periphery filter chamber blow-off pipe simultaneously, the filtrate of the pressure backwash periphery filter chamber through water in the collecting chamber.The utility model has been realized uninterrupted product water, has improved production efficiency, has reduced the operation cost of equipment.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1, a kind of sand filter comprises support component 7, collecting chamber 9 and the outlet pipe 8 of the pressure resistant vessel 10 that is made up of ellipse head and cylindrical shell, filter material layer 6, support filter material layer.In the pressure resistant vessel; Be provided with an axially extended inner core 3 between support component and the upper cover; Upper cover is built-in with water distributing plate 13; Water distributing plate and inner core are divided into center intake chamber 15 with pressure resistant vessel and are respectively equipped with independent water inlet pipe (1 and 14) and water intaking valve with periphery intake chamber 2 and corresponding filter chamber, center 12 with periphery filter chamber 5, center intake chamber and periphery intake chamber, and filter chamber, center and periphery filter chamber are respectively equipped with independent blow-off pipe (11 and 4) and blowoff valve.
During use, when needing the filtrate of filter chamber, backwash center, the water intaking valve of closing center's intake chamber water inlet pipe is opened the blowoff valve of filter chamber, center blow-off pipe simultaneously, the filtrate of the filter chamber, pressure backwash center through water in the collecting chamber; During the filtrate of backwash periphery filter chamber, close the water intaking valve of periphery filter chamber water inlet pipe, open the blowoff valve of periphery filter chamber blow-off pipe simultaneously, the filtrate of the pressure backwash periphery filter chamber through water in the collecting chamber.The utility model has been realized uninterrupted product water, has improved production efficiency, has reduced the operation cost of equipment.
