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 technique
According to the difference of sewage treatment situation, sewage source heat pump can be divided into be made with untreated sewage i.e. native sewage water
For heat source and using treated sewage as the sewage source heat pump of heat source[1].With treated sewage, that is, secondary effluent or middle water
Make source heat pump heat, water quality is preferable, and treatment process is fairly simple, and system only needs grade one filter[2].But due to sewage
Treatment plant is normally at city's area edge, away from heat user distance farther out, 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 system sewerage disposing[3]。
It is found using grade one filter, since some tough sludge are adhered to filter inner wall when filter works
On, plugged filter, processing capacity decline are caused for a long time.In addition, also easily causing the pollution of working environment when Treatment of Sludge.
Summary of the invention
To solve the deficiencies in the prior art, of the invention that a kind of direct heat-exchanging type sewage source heat pump pretreatment unit is provided.
It is as follows using technical solution that the present invention solves its technical problem: a kind of spiral-flow type sewage filter device, the filtering
Device is made of the cartridge filter of symmetrical two cylinder types and intermediate inlet duct, is arranged on the inlet duct of the centre
The PLC controller for having differential pressure pickup and being electrically connected with the differential pressure pickup, the PLC controller control motor, the mistake
Filter cylinder is provided centrally with rotary grate, and the rotary grate is provided centrally with rotary shaft, electricity described in the rotation axis connection
Machine, the end of the rotary grate are connected with scraper, are provided with filter screen on the side wall of the cartridge filter, the filter screen it is outer
Portion is provided with mask, and the bottom of the cartridge filter is provided with sludge outlet, is provided with solenoid valve on the sludge outlet.
Two round sealed faces of the cartridge filter are set as Transparent color.
The end of the scraper is set as curved edge, and the arc range of the edge of a knife is at 45-175 °.
The end of the rotary grate is inserted into pin shaft hole by pin shaft and is fixedly connected with the scraper.
The mask is articulated on 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, cause to import and export intracavitary generate centainly
Pressure difference after pressure sensor detection, starts motor by PLC controller, motor drives grid rotation when pressure difference reaches upper limit value
90 °, stop 0-30 seconds is then slightly done, this time is adjustable, continues to stop after being rotated by 90 °, completes the operating of a cycle.When
When rotary grate completes first 90 °, limit switch issues signal, starts sewage draining exit electromagnetism valve events, opens blowdown；Work as delay
After time arrives, blowoff electromagnetic valve is closed.Similarly, continue above-mentioned action step.
Beneficial effects of the present invention:
1, the present invention is reached using the scraper blades scrape sludge on the rotary grate in filter by solenoid valve control blowdown
Pollutant in sewage is removed, and structure is simple, low in cost.
2, it is symmetrically arranged with the mask of disassembling cleaning on cartridge filter of the invention, prevents sludge from disorderly splashing, protects work
The environment of processing is clean.
3, present invention setting arc scraper, improves scraper blades scrape sludge ability, promotes the cleaning efficiency of filter.
4, scraper of the invention and grid are connected and fixed using pin shaft, scraper removable and replaceable, adjust scrape as needed
The radian of knife reaches optimal sludge shaving effect.

Specific 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 a cylinder type and intermediate inlet duct 1 are constituted, and are provided with differential pressure pickup on the inlet duct 1 of the centre
11 and the PLC controller 12 that is electrically connected with differential pressure pickup 11, filter screen 3 is provided on 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 as Transparent color, the filter screen 3
Outside be provided with dismountable mask 4, the mask 4 is symmetrically set with two, and the mask 4 is articulated with institute
It states on cartridge filter 2, the cartridge filter 2 is provided centrally with rotary grate 5, and 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
It is inserted into pin shaft hole 14 by pin shaft and is fixedly connected with scraper 6, as shown in Fig. 2, the pin shaft of the present embodiment and pin shaft hole 14 are provided with 4
Set, in order to increase the overstrain of scraping to sludge, the end of the scraper 6 is set as curved edge 15, and the arc range of the edge of a knife 15 exists
It 45-175 °, adjusts as needed, the bottom of the cartridge filter 2 is provided with sludge outlet 7, is provided with solenoid valve on sludge outlet 7
