Description
Technical field
The present invention relates to filter, specifically a kind of full automatic corrupt brushing backwash water filter.
Background technology
Water filter is mainly used in and is the thermal power plant; be suitable for being installed in the usefulness of doing filtration in the seawater of thermal power plant or the fresh water water system; preventing that bringing various solid particles and filthy foreign material etc. in the water into enters the water system and the watering equipment in downstream, thereby purify water and protect the safety of equipment.Also be applicable to the usefulness that the work such as water system, waste water recovery, cooling water system, agricultural irrigation, sea-farming, regional water system of various industry purifies water simultaneously.
The plugging of filthy particle foreign material or the blocking channel that prevent to be cooled tubule footpath heat exchanger tube in the power plant and plate type heat exchanger water brings into reduce cooling effect and safety in operation.As the heat exchanger of the oil cooler of power plant and aerial cooler and so on, generally need to install water filter on the cooling water pipeline.
Prevent larger-size solid particle and filthy foreign material access arrangement, particularly slewing,, guarantee reliable safety in order to avoid cause and block or damage.Prevent that block foreign material from stopping up power plant and the fountain of industrial cooling system and the nozzle of various water injection systems.Require the aquaculture and the flowers and trees plant husbandry of clean water to do the filtration of supplying water.The water rich and influential family's of steel plant water supply and sewage recovering system filter.
Because existing water filter does not have the automatic backwash function mostly, after using a period of time, just need be out of service, clean the foreign material that are adsorbed on screen surface, therefore both bothered, can have influence on normal production again.
Summary of the invention
The objective of the invention is to design a kind of full automatic corrupt brushing backwash water filter, this water filter in use for some time can be according to the pressure reduction of reality import and export, voluntarily filter screen is cleaned and backwash, thereby guaranteed the normal operation of water filter, alleviated working strength of workers, improved system and exerted oneself.
According to technical scheme provided by the invention, filter screen is arranged in housing, it is characterized in that: reductor is installed on housing, and several filter screens cylindraceous are installed on the support equably, and support and main shaft link together, and main shaft is connected with the output of reductor; In each filter screen, rotating shaft is arranged, brush is arranged in rotating shaft, the end of this brush contacts with the inwall of filter screen, filter screen is stretched out in the end of rotating shaft, and planetary gear is set in the end of rotating shaft, each planetary gear meshes with the gear wheel that is fixed in the housing respectively, in lower part of frame water inlet and delivery port and sewage draining exit is set.
Upper end at housing is equipped with supporting seat, and reductor is positioned on the supporting seat, and motor is arranged on reductor, between the output of main shaft and reductor shaft coupling is arranged.On the water inlet of housing and delivery port the filter screen measuring point is set, this filter screen measuring point utilizes instrument piping to be connected with differential pressure switch, and instrument needle-valve and Pressure gauge are set on instrument piping, between Pressure gauge and instrument piping separator tube is arranged.Brush in each filter screen is symmetrically located in the rotating shaft.
The present invention has good backwashing function, can clean filter screen easily under the normal water supply state, removes the filthy material on the influent side surface of filter screen, improves utilization rate of equipment and installations, alleviates labor cleaning's heavy work.Backwashing time is short, and water content consumption is few, energy efficient.To choose different materials and anticorrosive measure to the critical piece of crossing aquaporin according to user's use water quality fresh water or seawater in design, to guarantee the reliability service and the service life of water filter.

The specific embodiment
As shown in the figure: filter screen 3 is arranged in housing 2, it is characterized in that: reductor 9 is installed on housing 2, and several filter screens 3 cylindraceous are installed on the support equably, and support and main shaft 26 link together, and main shaft 26 is connected with the output of reductor 9; In each filter screen 3, rotating shaft 25 is arranged, brush 4 is arranged in rotating shaft 25, the end of this brush 4 contacts with the inwall of filter screen 3, filter screen 3 is stretched out in the end of rotating shaft 25, and planetary gear 5 is set in the end of rotating shaft 25, each planetary gear 5 meshes with the gear wheel 11 that is fixed in the housing 2 respectively, and water inlet 22 and delivery port 23 and sewage draining exit 24 are set in the bottom of housing 2.Drive in filter screen 3 rotating process at main shaft 26, the duty of each filter screen 3 is different, when certain filter screen 3 is rotated the filtration station, begins the water of coming in from water inlet 22 is filtered; Turn to the backwash station when the needs blowdown, dirt is discharged by sewage draining exit 24.So just can guarantee whole water filter continuous operation.
In the upper end of housing 2 supporting seat 8 is installed, reductor 9 is positioned on the supporting seat 8, on reductor 9 motor is arranged, and between the output of main shaft 26 and reductor 9 shaft coupling 10 is arranged.Actuating motor, the motor drives reductor rotates, and the output of reductor drives main shaft 26 by shaft coupling 10 and rotates.
On the water inlet 22 of housing 2 and delivery port 23, filter screen measuring point 18 is set, this filter screen measuring point 18 utilizes instrument piping 17 to be connected with differential pressure switch 15, and instrument needle-valve 16 and Pressure gauge 13 are set on instrument piping 17, at Pressure gauge 13 and 17 of instrument pipings separator tube 14 is arranged.So that filter screen is monitored in real time, the information that obtains is transported in the controller in the control cabinet 21 and handles.
During the water filter blowdown, driving main shaft 26 by reductor 9 by shaft coupling 10 rotates, main shaft 26 drives all filter screens 3 by support and rotates (5 filter screens are arranged among the figure) around main shaft 26, also rotation when the planetary gear 5 on each filter screen 3 rotates around fixing gear wheel 11 with filter screen 3, thereby the rotating shaft 25 and the brush 4 thereof that drive in every filter screen 3 rotate in filter screen 3, and filter screen 3 is scrubbed.When each filter screen 3 forwarded the delivery port of sewage draining exit 24 to, the aqueous reflux in the water filter went in the filter screen to survey, and to the filter screen flushing, took away the dirt that brushes down and discharged from sewage draining exit 24, thereby realize backwash.
Characteristics of the present invention are as follows:
A, intake-outlet adopt the design of " online " formula, and be on same center line, easy for installation. B, backwash The water yield is few, can be for carrying out continuous backwash under the water state, and constantly blowdown contains the mistake of sewage to solve height Filter. C, compact conformation, made of light design. D, adopt planetary rotation mode, make single filter core rotation extremely Assigned address carries out backwash. E, the built-in cover rotating brush of each filter core can brush the impurity on the filter core.
The present invention compares with existing product, has bigger filter area, and water-flowing amount is big, and resistance is little, and is clear The characteristics such as the cycle of washing is long, but basic installation dimension is similar to existing product with the pipe joint size, therefore suitable Be suitable for the original water filter of power plant to undergo technological transformation and equipment replacement. On mode of operation, manual operation is arranged With the semi-automatic operation dual mode, selected by the user. It is supporting and big that the present invention is suitable for newly-built power plant simultaneously The usefulness of type power plant technological transformation.
