As a further improvement of the above technical scheme:
Dirt discharge groove is set in rotary drum inner upper, backwash mechanism, the spray of backwash mechanism are set in filter tank top of the box Shower pipe is arranged above rotary drum, and bath import is connected to spray tube, and import of washing by water is connected to rotary drum filter tank case by suction channel In vivo.
In the filter cloth of rotary drum periphery package plain weave.
In filter tank, sewage pipe is arranged in cabinet front plate or back plate, and the dirt discharge groove is connect with sewage pipe, sewage pipe and evacuated tube It connects and in communication.
In filter tank, upper liquid level sensor and lower liquid level sensor is arranged in box house, and upper liquid level sensor is lower than dirt discharge groove Minimum point, lower liquid level sensor is below rotary drum.
Several spray heads are set on spray tube, and backwash mechanism pumps driving spray by suction irrigation.
In filter tank, overflow hole is arranged in box house, and overflow hole is below dirt discharge groove.
The beneficial effects of the utility model are as follows:
The filter tank cabinet of the utility model includes the front and rear panels that left plate, right side plate and bottom bend inwards, filter Pond cabinet is set on the base, and the front and rear panels to bend inwards can reduce the volume of filter tank cabinet, reduces the water-filling stage Water consumption avoids the waste of water resource.In the filter cloth of rotary drum periphery package metal material, filter cloth uses plain weave, filter cloth bullet Property it is small stretching be unlikely to deform, wearability is good, and filter opening is evenly distributed, filtering accuracy stablize, can efficiently go water removal in suspended matter, filtering Precision can achieve 10um or less.
In filter tank top of the box, backwash mechanism is set, the spray tube of backwash mechanism is horizontally set on right above rotary drum, The setting bath import on left plate is connected to spray tube, bath import is connected in the cabinet of filter tank by suction channel, is sprayed Several spray heads are set on pipe, and backwash mechanism pumps driving spray by suction irrigation.Backwashing water is recycled using filtered clear water It uses, water consumption greatly reduces, and filter process is still carrying out at this time, and backwash process and filter process carry out simultaneously, reduces The working time of filter improves working efficiency.
Detailed description of the invention
Fig. 1 is the main view of the utility model.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the left view of Fig. 1.
In figure: 1, import of washing by water;2, rotary drum driving device;3, filter tank cabinet;4, water outlet;5, pedestal;6, evacuated tube;7, Water inlet;8, sewage pipe;9, drain.
Specific embodiment
With reference to the accompanying drawing, illustrate specific embodiment of the present utility model.
As shown in Figure 1, the filter tank cabinet 3 of the utility model includes before left plate, right side plate and bottom bend inwards Plate and back plate, filter tank cabinet 3 are arranged on pedestal 5, and the front and rear panels to bend inwards can reduce the volume of filter tank cabinet 3, The water consumption for reducing the water-filling stage, avoids the waste of water resource.In filter tank, water inlet 7 is arranged in 3 right side plate middle and lower part of cabinet, on a left side Water outlet 4 is arranged in side plate bottom, is connected to inside water outlet 4 and filter tank cabinet 3.The setting of water inlet 7 is corresponded to inside filter tank cabinet 3 It is connected to inside horizontal rotary drum, water inlet 7 and rotary drum, the position setting rotary drum that 3 left plate of cabinet corresponds to rotary drum in filter tank drives Device 2, rotary drum driving device 2 is for driving drum rotating.In the filter cloth of rotary drum periphery package metal material, filter cloth uses plain weave Braiding, the small stretching of filter cloth elasticity are unlikely to deform, and wearability is good, and filter opening is evenly distributed, and filtering accuracy is stablized, and can efficiently go in water removal Suspended matter, filtering accuracy can achieve 10um or less.
It is arranged in an axially parallel mode dirt discharge groove in rotary drum inner upper and rotary drum, 3 foreboard of cabinet is arranged close to right side plate in filter tank Vertical sewage pipe 8, dirt discharge groove are connect with sewage pipe 8, and evacuated tube 6 that is normal thereto and being connected to is arranged in 8 bottom of sewage pipe, preceding Sewage pipe 8 is arranged in board bottom portion, and sewage pipe 8 passes through piping connection to evacuated tube 6.It is set inside the filter tank cabinet 3 of 7 side of water inlet Liquid level sensor and lower liquid level sensor are set, upper liquid level sensor is lower than the minimum point of dirt discharge groove, when foreign matter Severe blockage is filtered When cloth, when the water level in rotary drum is increased to contact liquid level sensor, upper liquid level sensor issues full level alarm.Lower level sensing Device is below rotary drum, close to rotary drum minimum point.
Backwash mechanism is set at the top of filter tank cabinet 3, the spray tube of backwash mechanism is horizontally set on right above rotary drum, The setting bath import 1 on left plate is connected to spray tube, bath import 1 is connected in filter tank cabinet 3 by suction channel, is sprayed Several spray heads are set in shower pipe, and backwash mechanism pumps driving spray by suction irrigation.
When utility model works, the water-filling first into filter tank cabinet 3, water-filling can reduce the influent load in rotary drum, When the bottom that water-filling water level reaches rotary drum contacts lower liquid level sensor, lower level sensor contact closure, starting rotary drum driving Device 2, rotary drum start to rotate, and sewage slowly enters in rotary drum from water inlet 7, and the water level in rotary drum remains at rotary drum axis 100 ~ 150mm under line.Through the filter-cloth filtering being wrapped on rotary drum into the sewage in rotary drum, a large amount of impurity are attached in filter cloth Surface, open suction irrigation pump, suction irrigation pump the clear water filtered is constantly aspirated out of filter tank outside rotary drum, from rinse into The spray head that mouth enters through spray tube is sprayed on filter cloth, the impurity on filter cloth is inwardly washed from removing, impurity falls into dirt discharge groove It is discharged afterwards from sewage pipe 8, backwashing water is recycled using filtered clear water, and water consumption greatly reduces, at this time filter process It is still carrying out, backwash process and filter process carry out simultaneously, reduce the working time of filter, improve working efficiency.
Above description is the explanation to the utility model, is not the restriction to utility model, without prejudice to the utility model In the case where spirit, the utility model can make any type of modification.Such as it can be not provided with liquid level sensor, it is intaking Overflow hole is set on the filter tank cabinet 3 of 7 positions of mouth, overflow hole is below dirt discharge groove, close to dirt discharge groove minimum point, overflow hole and row Dirty pipe 8 connects, and when water level is excessively high, sewage flows directly into sewage pipe 8, guaranteed water level safety.Sewage pipe 8 and evacuated tube 6 can also To be arranged in back plate, the purpose of blowdown equally may be implemented.
