Description
Technical field
This utility model relates to technical field of sewage, particularly relates to a kind of sigma type scraper plate and scrapes mud
Machine.
Background technology
Chain type mud scraper is mainly used in rectangular sedimentation tank, especially the silt pond of sewage treatment plant, preliminary sedimentation tank,
Sand discharge, spoil disposal at the bottom of the rectangle form pool ponds such as second pond, chain type mud scraper is provided with the carrier chain of two parallel seals, defeated
Sending equipped with organizing cleaning shoe on chain, under the drive of driving means, carrier chain and cleaning shoe are upper and lower along sedimentation tank more
Do around running, when cleaning shoe is in motion at the bottom of pond, sludge scraping collection at the bottom of pond will be deposited to warp in mud drainage slot
Sludge pump is discharged；When cleaning shoe is at cell body surface motions, the scum silica frost of the water surface can be scraped again and skim in scum trough
Discharge, thus complete the purpose of first machinery water purification.
For improving its corrosion resistance, general mud scraper uses nonmetal chain and nonmetal cleaning shoe, nonmetal
Cleaning shoe is typically made up of two backplates of scraper plate and scraper plate the same side, due to its use (big for non-metallic material
It mostly is plastics or thermoplastic polyester), therefore there is following two large problems in this scraper plate: 1, poor rigidity, easily turns round
Bent；2, amount of deflection is big, reaches 1/1000, this two large problems, and not only affect mud scraper scrapes mud and skimming effect,
Scraper plate is the most easily made to be twisted off；And if by scraper plate thickening, scraper plate can be caused the most again to conduct oneself with dignity to be increased, so that
Load and running resistance when scraper plate runs increase, and make operational efficiency reduce, and impact is normal to be produced.
Utility model content
The purpose of this utility model is for technological deficiency present in prior art, and provides a kind of Sigma
Type scraper plate and mud scraper.
Be the technical scheme is that by realizing the purpose of this utility model
A kind of sigma type scraper plate, including support edge, is integrally formed in the upper and lower dual-side in support edge and is positioned at
Upper limb limit inside support limit and bottom wing limit, be formed with longitudinal extension and inwardly protruded in the middle part of described support edge
Support bending.
The described bending that supports includes the bending section of both sides, connects the circular arc type top section that two bending sections are inner, with
And the circular arc linkage section of the flat part of two bending section outer ends and the support edge described in connecting.
The perpendicular setting of bending section of described both sides.
Described upper limb limit is isometric with described bottom wing limit, and described upper limb limit inner end is formed near bottom wing
The circular arc bending section on limit.
The central angle of described circular arc bending section is 90 degree.
The inner on described bottom wing limit and outer end divide be formed near and away from the reinforcement rib on described upper limb limit.
Described bottom wing limit and the spacing being smaller than upper limb limit and bending bending supporting bending.
It is by Fiberglass-reinforced Plastics Pultrusion Technology And Its Products.
A kind of mud scraper, including nonmetal chain, and multiple compartment of terrain is fixedly installed on described nonmetal
Sigma type scraper plate described on chain.
Compared with prior art, the beneficial effects of the utility model are:
Cleaning shoe upper limb limit of the present utility model, bottom wing limit and middle angled support edge composition one are complete
Whole entirety, structural strength is higher.Support edge is at an angle of the key that bending is structure, divides according to mechanics stress
Analysis, this structural rigidity, intensity are higher.
Accompanying drawing explanation
Fig. 1 show the structural representation of sigma type scraper plate of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.Should be appreciated that
Specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
As it is shown in figure 1, sigma type scraper plate of the present utility model is Fiberglass-reinforced Plastics Pultrusion Technology And Its Products, it includes supporting
Limit 1, is integrally formed in the upper and lower dual-side in support edge and is positioned at the upper limb limit 2 inside support edge and bottom wing limit 3,
Longitudinal extension and inwardly protruded support bending 4 it is formed with, propping up of described support edge in the middle part of described support edge
Support bending upper and lower is respectively flat part, is arc transition between described flat part and upper limb limit.That is,
The cross section of this scraper plate is in " Σ " type.
Specifically, described support bending and include living apart the bending section 5,6 of upper and lower both sides, connect two bendings
The circular arc type top section that section is inner, and the flat part on two bending section outer ends described in connecting and straight support limit
Circular arc linkage section.Preferably, the perpendicular setting of bending section 5,6 of described both sides.I.e. two bending section structures
The bending angle 7 become is 90 °, and described bottom wing limit is smaller than upper limb limit and bending bending with support bending
Spacing.
Cleaning shoe upper limb limit of the present utility model, bottom wing limit, middle angularly support edge form one completely
Entirety, structural strength is higher.Support edge is at an angle of the key that bending is structure, according to mechanics force analysis,
This structural rigidity, intensity are higher.
Specifically, for improving bulk strength and scraping mud effect, described upper limb limit and described bottom wing limit etc.
Long, described upper limb limit inner end is formed with the circular arc bending section near bottom wing limit, it is preferable that described circle
The central angle of arc bending section is 90 degree.Meanwhile, described bottom wing limit is formed by near and far inner dividing with outer end
Reinforcement rib from described upper limb limit.
This utility model further simultaneously discloses a kind of mud scraper, and it includes nonmetal chain, and multiple interval
The described sigma type scraper plate that is fixedly installed on described nonmetal chain, described sigma type is scraped
The flat part of the support edge of plate and scraper plate are fixing to be connected, near bottom side, pond when bottom wing limit is for scraping mud.
Using mud scraper of the present utility model, scraper plate intensity is high, can effectively be used to strike off moisture content at the bottom of pond and be more than
The muddy water of 95%, it is ensured that operation, long-life continuously.
The above is only preferred implementation of the present utility model, it is noted that lead for this technology
For the those of ordinary skill in territory, on the premise of without departing from this utility model principle, it is also possible to make some
Improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
