Description
Technical field
The utility model relates to disc filter, belongs to more medium filter field.
Background technology
More medium filter be rely in filter fill variety classes, different size particle as water purification medium, and by water purification medium by the impurity in water and rejection to organics in filter.But, existing more medium filter big yield just wash with backwash after, will there is random layer phenomenon in different water purification media, after random layer occurs different water purification media, more medium filter also just loses the effect of different impurities in water being filtered respectively in filter.And different water purification media, after random layer, just needs it to take out in filter, and after different water purification media is sieved by kind, just can be reinstalled in filter and use.
Summary of the invention
Problem to be solved in the utility model just there is provided a kind of disc filter, solves the problem that random layer occurs water purification medium.
For solving the problem, the utility model provides following technical scheme: disc filter, comprise housing, described housing is provided with water inlet and delivery port, described housing is provided with drainage chamber between described water inlet and described delivery port, drainage assembly is provided with in described drainage chamber, described drainage assembly comprises outlet pipe, first screen drum and the second screen drum, described first screen drum is enclosed within described outlet pipe, the first water purification medium is provided with between described first screen drum and described outlet pipe, described second screen drum is enclosed within described first screen drum, the second water purification medium is provided with between described second screen drum and described first screen drum, the end envelope of described first screen drum has the first cover plate, the end envelope of described second screen drum has the second cover plate, described outlet pipe one end extends to outside described first screen drum through described first cover plate and is connected with described delivery port, the tube wall that described outlet pipe is positioned at described first screen drum is provided with water flow hole.
In disc filter of the present utility model, drainage assembly is for removing impurity in water and organic matter, and drainage assembly comprises outlet pipe, the first screen drum and the second screen drum, and the first screen drum is enclosed within outlet pipe, and the second screen drum is enclosed within the first screen drum.The end envelope of the second sleeve has the second cover plate, second cover plate can be avoided being with the water filtered just not flowing directly in the first screen drum through the second water purification medium, so the second cover plate can avoid the second water purification medium be arranged between the first screen drum and the second screen drum to lose water purification effect.Meanwhile, the second water purification medium can be avoided after the second screen drum and the second cover plate assemble to shed in the second screen drum, thus mix with the first water purification medium.The end of the first sleeve is provided with the first cover plate, first cover plate can avoid disc filter in the process of backwash, the water that band filters just does not flow directly in the second screen drum through the first water purification medium, so the first cover plate can avoid the first water purification medium be arranged between the first screen drum and outlet pipe to lose water purification effect.Meanwhile, the first water purification medium can be avoided after the first screen drum and the first cover plate assemble to shed in the first screen drum, thus mix with the second water purification medium.The tube wall fan that outlet pipe is positioned at the first screen drum is provided with water flow hole, and water flow hole is so that the water after filtering flows in outlet pipe.
In the utility model, water to be cleaned enters the second screen drum from the sidewall of the second screen drum, and within the unit interval, discharge remains unchanged, this structure by increasing the circulation area of water, thus adds the operating efficiency of disc filter.
Further, described outlet pipe is positioned at the end of described first screen drum and described first cover plate is fixed together.This structure can be avoided between outlet pipe and the first sleeve owing to being filled with the first water purification medium, and cause outlet pipe that position skew occurs, after outlet pipe offset in place moves, outlet pipe on part direction and the gap between the first sleeve will reduce, this can cause the water flowing through this region dirtier than the water flowing through other regions, namely impurity and content of organics high.
Further, when described first screen drum is concordant with described second screen drum end, described second cover plate is the first cover plate, and described second cover plate can seal the end of described first screen drum and described second screen drum simultaneously.This structure can simplify the structure of drainage assembly, thus is convenient to the maintenance of disc filter.
Further, the bottom of described housing is provided with support column.Support column is for improving the height of delivery port, and this structure workman that is convenient to operation fetches water at water outlet.
Further, described disc filter also can be used for backwash.So-called backwash is exactly that water to be filtered is intake from delivery port, and from water inlet water outlet, this structure so that water to be filtered repeatedly filters in a disc filter, thus makes impurity in water and rejection to organics in filter assemblies.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model disc filter.
Detailed description of the invention
With reference to Fig. 1, disc filter, comprises housing 1, and the top end face of housing 1 is provided with water inlet 11, and the bottom face of housing 1 is provided with delivery port 12, is provided with drainage chamber 13 in housing 1, and water inlet 11 is communicated with drainage chamber 13 with delivery port 12.Drainage assembly is provided with in drainage chamber 13, drainage assembly comprises the second screen drum 2, first screen drum 3, outlet pipe 4, second water purification medium 5, first water purification medium 6 and the second cover plate 7, first screen drum 3 is enclosed within outlet pipe 4, second screen drum 2 is enclosed within the first screen drum 3, second water purification medium 5 is arranged between the second screen drum 2 and the first screen drum 3, first water purification medium 6 is arranged between the first screen drum 3 and outlet pipe 4, the top end face of the second screen drum 2, the top end face of the first screen drum 3 is concordant with the top end face of outlet pipe 4, and three is sealed by the second cover plate 7 simultaneously, the bottom face of the second screen drum 2 is concordant with the bottom face of the first screen drum 3, and the two is sealed by the second cover plate 8 simultaneously, the bottom of outlet pipe 4 extends to outside the first screen drum 3 through the second cover plate 8, and be connected with delivery port 12, the tube wall that outlet pipe 4 is positioned at the first screen drum 3 is provided with water flow hole.
