Technical field
The present invention relates to the sewage water filtration technical field, especially a kind of anti-freeze type filter.
Background technology
Filtering ponds all have very critical role in the fields such as town water supply processing, industrial water supply processing, industrial cycle water treatment, sewage disposal.Current the most frequently used filtering ponds, mostly by the pond body, the filtrate filtering layer, filtrate bearing device and for the compositions such as water dispensing apparatus of backwash filtrate, filtrate generally adopts quartz sand, the various materials such as anthracite or fiber filtering, the Chinese invention patent " a kind of fibrous filtering pool " that is ZL200510049755.1 (publication number is CN1712096A) as the patent No. discloses a kind of filtering ponds that adopt fiber filtering, it includes filter chamber, the intake chamber of top, filter chamber and the backwash water dispensing apparatus of filter chamber's one side, this filter chamber comprises the gear filtering device from top to bottom successively, filtering layer, the gentle hydroecium of filtrate bearing device, wherein, be furnished with uniformly strainer head toward contact on the filtrate bearing device between the gentle hydroecium of filtering layer, this backwash water dispensing apparatus comprises the channel of upper and lower two-layer setting, be that upper strata is the backwash rhone adjacent with the gear filtering device, the air water distributing channel of lower floor for being connected with the air water chamber.These filtering ponds are when backwash, air water in the air water distributing channel is from the intercommunicating pore of itself and air water chamber, be air distribution hole and distributing hole, enter the air water chamber, then rinse filtrate by the strainer head on the filtrate bearing device, current overflow through the gear filtering device above filtering layer, thereby flow into the backwash rhone of a side.
The structure of existing filtering ponds can spring back over the problem in the blowdown district by the water in water inlet pipe in back flushing process.
Summary of the invention
The technical problem to be solved in the present invention is: carry the disadvantage that enters lower water into water when the backwash for existing filter tank.
The technical solution adopted for the present invention to solve the technical problems is: a kind of anti-freeze type filter, there are two cylindrical shells, and by connecting communicating pipe, be arranged on the middle part of cylinder body outer wall communicating pipe between two cylindrical shells, communicating pipe is for the hydraulic pressure between two cylindrical shells of balance.Be provided with soil chamber in cylindrical shell, water-purifying cavity and adapter cavity, soil chamber, water-purifying cavity is separated by filter course and adapter cavity, soil chamber is in water-purifying cavity, the delivery port of soil chamber is in filter course, the water inlet of water-purifying cavity adapter cavity in filter course is arranged on the bottom of cylindrical shell, be outside equipped with water feed apparatus at cylindrical shell, water feed apparatus has a house steward, both sides house steward are connected with outlet pipe, be connected with water inlet pipe on outlet pipe, be provided with control valve on the pipeline between house steward and water inlet pipe, be provided with control valve on water inlet pipe, the outlet pipe of water feed apparatus is connected with the soil chamber in cylindrical shell.
Be provided with blow-off pipe at adapter cavity in the present invention, be provided with control valve on blow-off pipe.
In the bottom of filter course, the resistance filter cap is installed in the present invention.
The invention has the beneficial effects as follows, of the present invention self realize antifreeze: therefore between two filter tanks, be interconnected, the water between filter tank circulates mutually, utilizes the heat of filter flowing water can realize that self is antifreeze; Designs simplification, reliable: back with water inlet line and backwash water pipeline unite two into one, and only need 2 valve auto-alternates just can realize filtering and backwash; Water saving: its water inlet in backwash process of traditional filter tank does not stop, but, along with backwash water is drained, this filter tank is to cut off water inlet when backwash.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is schematic top plan view of the present invention;
Fig. 2 is that the A of Fig. 1 is to schematic diagram;
Fig. 3 is B-B generalized section in Fig. 1.
In figure 1, cylindrical shell, 11, soil chamber, 12, water-purifying cavity, 13, adapter cavity, 14, filter course, 2, communicating pipe, 3, water feed apparatus, 32, outlet pipe, 33, water inlet pipe.
The specific embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
Anti-freeze type filter as shown in FIG., have between 1, two cylindrical shell 1 of two cylindrical shells and connect by communicating pipe 2, and communicating pipe 2 is arranged on the middle part of cylindrical shell 1 outer wall, and communicating pipe is for the hydraulic pressure between two cylindrical shells 1 of balance.Be provided with soil chamber 11 in cylindrical shell 1, water-purifying cavity 12 and adapter cavity 12, soil chamber 11, water-purifying cavity 12 is separated by filter course 14 and adapter cavity 13, soil chamber 11 is in water-purifying cavity 12, the delivery port of soil chamber 11 is in filter course 14, the water inlet of water-purifying cavity 12 is in filter course 14, adapter cavity 13 is arranged on the bottom of cylindrical shell 1, be outside equipped with water feed apparatus 3 at cylindrical shell 1, water feed apparatus has a house steward, be connected with outlet pipe 32 in house steward's both sides, be connected with water inlet pipe 33 on outlet pipe 32, be provided with control valve on the pipeline between house steward and water inlet pipe 33, be provided with control valve on water inlet pipe 33, the outlet pipe 32 of water feed apparatus 3 is connected with the soil chamber 11 in cylindrical shell 1.Top at cylindrical shell 1 is provided with drainpipe, for discharging water-purifying cavity 12 back warps, crosses the clear water of twice filtration.Be provided with blow-off pipe at adapter cavity 13, blow-off pipe is provided with control valve.The filter controlling system adopts the integrated control mode of operating room PLC.
