Description
Technical field
The invention belongs to sewage source heat pump field of water treatment equipment, and in particular to a kind of spiral-flow type sewage filter device.
Background technology
According to the difference of sewage disposal situation, sewage source heat pump can be divided into be made with untreated sewage i.e. native sewage water
The sewage source heat pump of thermal source is used as thermal source and using the sewage after processing[1].It is secondary effluent or reclaimed water with the sewage after processing
Make source heat pump heat, preferably, processing procedure is fairly simple, and system only needs grade one filter for water quality[2].But, due to sewage
Treatment plant is normally at city's area edge, distant away from heat user, if heated pump station is located in sewage treatment plant, heat supply pipeline compared with
Long, heat loss is larger, and also increases the investment cost of heat pump sewerage disposing[3]。
Found using grade one filter, because some tough sludge stick to filter inwall when filter works
On, plugged filter is caused for a long time, and disposal ability declines.In addition, during Treatment of Sludge, also easily causing the pollution of working environment.
The content of the invention
To solve the deficiencies in the prior art, a kind of direct heat-exchanging type sewage source heat pump pretreatment unit of offer of the invention.
It is as follows using technical scheme that the present invention solves its technical problem：A kind of spiral-flow type sewage filter device, the filtering
Device is made up of the cartridge filter and middle inlet duct of symmetrical two cylinder types, is set on the inlet duct of the centre
There are differential pressure pickup and the PLC electrically connected with the differential pressure pickup, the PLC controlled motor, the mistake
Filter cylinder is provided centrally with rotary grate, and the rotary grate is provided centrally with rotary shaft, and the rotary shaft connects the electricity
Machine, the end of the rotary grate, which is connected with scraper, the side wall of the cartridge filter, is provided with screen pack, outside the screen pack
Portion is provided with mask, and the bottom of the cartridge filter, which is provided with sludge outlet, the sludge outlet, is provided with magnetic valve.
Two round sealed faces of the cartridge filter are set to Transparent color.
The end of the scraper is set to curved edge, and the arc range of the edge of a knife is at 45-175 °.
The end of the rotary grate is inserted in pin shaft hole by bearing pin and is fixedly connected with the scraper.
The mask is articulated with the cartridge filter, and the mask is detachable.
The number of the rotary grate is 6-12.
The mask is symmetrically set with two.
Rotary grate operating principle of the present invention：When build up of dirt in rotary grate, import and export intracavitary is caused to produce necessarily
Pressure difference, when pressure difference reaches higher limit, after pressure sensor detection, motor is started by PLC, motor drives grid rotation
90 °, stop 0-30 seconds is then slightly done, this time can be adjusted, continue to stop after being rotated by 90 °, complete the operating of a cycle.When
When rotary grate completes first 90 °, limit switch sends signal, starts sewage draining exit electromagnetism valve events, opens blowdown；Work as delay
After time arrives, blowoff electromagnetic valve is closed.Similarly, above-mentioned action step is continued.
Beneficial effects of the present invention：
1st, the present invention, by solenoid valve control blowdown, is reached using the scraper blades scrape sludge on the rotary grate in filter
Pollutant in sewage is removed, simple in construction, with low cost.
2nd, the mask of disassembling cleaning is symmetrically arranged with cartridge filter of the invention, prevents sludge from disorderly splashing, work is protected
The environment of processing is clean.
3rd, the present invention sets arc scraper, improves scraper blades scrape sludge ability, lifts the cleaning efficiency of filter.
4th, scraper and grid of the invention are connected using bearing pin, scraper removable and replaceable, and regulation as needed is scraped
The radian of knife reaches optimal sludge shaving effect.

Embodiment
Below in conjunction with drawings and examples, the present invention is described in further detail.
As shown in figure 1, a kind of spiral-flow type sewage filter device, including filter, the filter is by symmetrical two
The cartridge filter 2 of individual cylinder type and middle inlet duct 1 are constituted, and differential pressure pickup is provided with the inlet duct 1 of the centre
11 and the PLC 12 that is electrically connected with differential pressure pickup 11, screen pack 3 is provided with the side wall of the cartridge filter 2, in order to aobvious
Show and observe rotary grate internal operation situation, two round sealed faces 16 of cartridge filter 2 are set to Transparent color, the screen pack 3
Outside be provided with dismountable mask 4, the mask 4 is symmetrically set with two, and the mask 4 is articulated with institute
State on cartridge filter 2, the cartridge filter 2 is provided centrally with rotary grate 5, the rotary grate 5 is provided centrally with rotary shaft
13, the rotary shaft 13 connects the motor 9, and the number of the rotary grate 5 is 6-12,5 ends of the rotary grate
