Technique effect of the present utility model:
The utility model compared with prior art has following characteristics: (1) the utility model structural design novelty, the filtration disc is fixing not to be rotated, and in filtration stage and backwash stage, is in static state all the time.Filtration stage filters disc and is in static state, helps the pond bottom sediments of mud.The backwash stage, the filtration disc is fixing not to be rotated, and syringe pipe directly is installed on the backwash tube, and drive motors drives backwash tube by transmission mechanism and syringe pipe slowly rotates, each position of disc can both be rinsed totally, and filtration simultaneously is not affected.(2) syringe pipe on the adjacent filtration disc is installed along backwash tube axial direction symmetry, syringe pipe position on each disc is not overlapped mutually, reduced to filter the interval between the disc, the packing density that can increase the filtration disc reduces occupation area of equipment more than 30%.(3) also be provided with the spoil disposal suction pump in the body of pond, spoil disposal suction delivery side of pump also directly links to each other with backwash tube, has save the spoil disposal pipeline, has simplified device structure.(4) energy consumption is low, and the maximum head loss of equipment itself is less than or equal to 0.25m.(5) cost is low, and operating cost is low, and management is simple.Water outlet after the processing is under the condition of equal effluent quality, and the processed in units valency is lower than other advanced treating technology.
Description of drawings
Fig. 1 is the structural representation of filter cloth filter of the present invention.
Reference numeral lists as follows:
1-pond body, the pending water inlet of 2-, the 3-filtrate (liquid, 4-filters disc, 5-filtrate collecting pipe, the 6-motor, the suction pump of 7-spoil disposal, the 8-syringe pipe, the 9-backwash tube, 10-washes suction pump, 11-level sensor.
The specific embodiment
(Fig. 1) describes the utility model below in conjunction with accompanying drawing.
The purpose of this utility model provides a kind of novel filter cloth filter---fixed disc filter cloth filter, and this equipment has simple and compact for structure, and floor space is little, and disc does not have rotation in the running, and unique backwash process filters characteristics such as effluent quality is good.
Fixed disc filter cloth filter, as shown in Figure 1, comprise pond body 1, pending water inlet 2, filtrate (liquid 3, filter disc 4 and filtrate collecting pipe 5, described filtration disc is vertically installed, and filters the disc 4 outer cut velvet filter clothes that coat as filter medium, described filtrate collecting pipe 5 links to each other with filtrate (liquid 3, the filter cloth outer surface of described filtration disc 4 is provided with syringe pipe 8, is used to filter the backwash of disc 4, and described syringe pipe 8 links to each other by the backwash tube 9 flushing suction pump 10 external with being arranged on the pond.Be at the bottom of the bucket shape pond at the bottom of the pond of described pond body 1, establish spoil disposal suction pump 7 in the pond, spoil disposal suction pump outlet links to each other with backwash tube 9, and the interior mud mixture of backwash tube draws gets back to pretreatment system for sewage.
When syringe pipe 8 is installed, install along backwash tube 9 axial directions symmetry, avoid making syringe pipe 8 positions on the adjacent filtration disc 4 to overlap, so just reduced to filter the interval between the disc 4, increased the packing density of pond body inner filtration disc 4, even when syringe pipe rotates, can not bump each other simultaneously yet, not influence the cleaning of syringe pipe to filter cloth.Be at the bottom of the bucket shape pond at the bottom of the pond of the utility model pond body, also be provided with spoil disposal suction pump 7 in the body of pond, spoil disposal suction pump outlet links to each other with backwash tube 9.Water surface is provided with level sensor 11 in the external cell body in addition.
Fixed disc filter cloth filter, comprise pond body 1, the pool wall of pond body 1 is provided with pending water inlet 2 and filtrate (liquid 3, fixing the filtration disc 4 of several outsourcing filter clothes in the cavity of pond body, filter disc 4 and be communicated with filtrate (liquid 3 by filtrate collecting pipe 5, the surface of filtering disc 4 is provided with syringe pipe 8, is provided with in the cavity of pond body 1 and passes the rotating backwash tube 9 that filters disc 4, backwash tube 9 connects syringe pipe 8 and drive unit, and links to each other with flushing suction pump 10.Syringe pipe 8 is set directly on the backwash tube 9, and is dislocatedly distributed on the surface of adjacent filtration disc 4.Also be provided with spoil disposal suction pump 7 in the pond body 1, spoil disposal suction pump outlet links to each other with backwash tube 9.Described filter cloth is the cut velvet filter cloth.Be provided with level sensor 11 in the described pond body 1.Described drive unit comprises motor 6, and motor 6 is arranged in the pond body 1, connects backwash tube 9 by transmission mechanism.
Operation principle of the present utility model is: sewage at first enters pond body 1 by pending water inlet 2, rely on hydraulic pressure effect sewage by filtering disc 4, clear water after the filtration enters the filtrate collecting pipe 5 that filters the disc both sides respectively, discharges from filtrate (liquid 3 by downflow weir then.Along with gathering of mud on the filter cloth, the filter cloth filtration resistance increases, and the filter tank water level raises gradually.By height of water level in level sensor 11 detection cells, when water level reaches the backwash setting value, offer backwash process.During backwash, filter disc 4 and maintain static, drive motors 6 drives syringe pipe 8 and backwash tube 9 slowly rotates, and relies on the swabbing action of flushing suction pump 10, and the filtration disc is rinsed totally, does not influence filtration simultaneously.Pond body 1 is provided with at the bottom of the bucket shape pond, helps the collection of pool bottom sludge, but the setting-up time section by PLC control spoil disposal suction pump 7, is discharged pool bottom sludge by spoil disposal suction pump 7.
The course of work of the present utility model comprises: static filtering process, negative pressure backwash process, spoil disposal process.
(1) static filtering process: the sewage gravity current enters filter, is provided with the baffle plate energy-dissipating installation in the filter.Sewage filters by filter cloth, and filtered fluid is collected by the filtrate collecting pipe, and gravity current is discharged the pond body by overflow launder from delivery port.Whole process is continuous.
(2) negative pressure backwash process: during filtration, the part sludge absorption forms sludge blanket gradually in the filter cloth outside.Along with gathering of mud on the filter cloth, the filter cloth filtration resistance increases, and the filter tank water level raises gradually.By the height of water level in the level sensing device detection cell.When this water level reached backwash setting value (high water level), PLC can start suction pump, the beginning backwash process.In this process, filtration is not affected, but continuous filtration.Backwash process is intermittently.
(3) spoil disposal process: the filtration disc of fixed disc filter cloth filter has at the bottom of the bucket shape pond, helps the collection of pool bottom sludge.The sludge-tank bottom sediments has reduced the sludge quantity on the filter cloth, can prolong filter process, reduces backwash process.By setting the time period of spoil disposal process, when reaching setting value, PLC starts sludge pump, by the backwash tube pipeline mud is back to pretreatment system for sewage.
Should be pointed out that the above specific embodiment can make those skilled in the art more fully understand the invention, but do not limit the present invention in any way creation.Therefore, although this specification has been described in detail the invention with reference to drawings and Examples,, it will be appreciated by those skilled in the art that still and can make amendment or be equal to replacement the invention; And all do not break away from the technical scheme and the improvement thereof of the spirit and scope of the invention, and it all is encompassed in the middle of the protection domain of the invention patent.
