Abstract
The invention discloses a slag removal net in a blow-down pipeline. An upper filter net and a lower filter net are arranged on the inner wall of the blow-down pipeline, wherein the upper filter net is connected by virtue of a filter net handle; the cross section of the upper filter net is in a w-shaped form; a middle convex rib of the upper filter net faces a water incoming direction; two sides of the middle convex rib sink backwards, so that a slag accumulating part is formed; an inclined well is arranged on the joint of the filter net handle of a sewage pipeline; the inclined well is inclined towards the water incoming direction; clamping grooves are formed in two sides of the inclined well; the lower filter net is equal to the clamping grooves in inclination degree; two sides of the filter net handle are clamped in the clamping grooves; an active carbon layer is fixedly arranged on the middle lower part of the upper filter net; a pebble layer is fixedly arranged on the middle upper part of the lower filter net; and the pebble layer is connected to the wall of the blow-down pipe by virtue of a hoop. The slag removal net disclosed by the invention can relieve blockage, and since the cross section of the upper filter net is in the w-shaped form, the middle convex rib faces the water incoming direction and the sides of the middle convex rib sink backwards to form the slag accumulating part, the slag removal net can keep a filtering effect; and by virtue of the pebble layer and the active carbon layer, impurities are filtered and adsorbed, so that water quality is guaranteed.
Description
Technical field
The invention belongs to filter plant technical field, be specifically related to the slagging-off net in a kind of blow-off line.
Background technology
Gutter adds other auxiliary agent by high density polyethylene (HDPE) (HDPE) and the external form that formed is the undulatory novel water drainage plastics tubing that oozes, and permeable bellows is by groove punching, manages outer surrounding outsourcing needle-punched geotextiles and processes.The permeable bellows of single wall and the permeable bellows of double-walled can be divided into according to bellows type.Because the pore of this product is in trough and be strip, effectively overcome plane circular hole product easily blocked and affect the drawback of drainage effect, for different drainage requirements, the size of pore can be 10mm × 1mm-30mm × 3mm, and can be uniformly distributed in the scopes such as 360 degree, 270 degree, 180 degree, 90 degree, be widely used in the draining fields such as the higher side slope protection caused of highway, railway bed, subway engineering, Landfills, tunnel, greenbelt, sports ground and water content, and agricultural, the sub-irrigation of gardening, drainage system.It and flexible porous tube, plastic blind-ditch have become three large major products in China's civil engineering construction (seep water, draining).Municipal drainage pipe network looks discharge pressure size, can select both arms bellows and straight wall pipe.Straight wall pipe pressure ability to bear is comparatively strong, can be used for the pipe special of large-scale draining blowdown pipe network.Grease in building sewage conduct mostly is animal fat, these animal fats are the saturated fats being very easy to solidify, winter temperature once reduction will solidify, can connect the rubbish incidentals such as other hair while solidifying and form the strong design being similar to steel concrete, this structure is very easy to cause the blocking of building soil pipe.And once grease solidifies and blocks, usually need workman or automatic robot to enter building sewage conduct and clear up, time-consuming.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide the slagging-off net in a kind of blow-off line.
The technical scheme that the present invention takes is:
Slagging-off net in a kind of blow-off line, the top of blow-off line is provided with water inlet, the bottom of blow-off line is provided with delivery port, inwall is provided with screen pack and lower screen pack, upper screen pack is connected by screen pack handle, the cross section of upper screen pack becomes w shape, convex stupefied towards inflow direction in the middle part of it, convex stupefied both sides, middle part are recessed to form accumulated slag portion backward, the screen pack handle junction of sewage conduct is provided with inclined shaft, inclined shaft tilts to inflow direction, the both sides of inclined shaft are provided with draw-in groove, lower screen pack is identical with the gradient of draw-in groove, screen pack handle both sides are connected in draw-in groove, activated carbon layer is fixed in the middle and lower part of upper screen pack, gravelstone sublayer is fixed in the middle and upper part of lower screen pack, gravelstone sublayer by clamp connection on blowdown tube wall.
Further, the front of described upper screen pack be provided with tilt upward except slag plate, be provided with filter bores except on slag plate, except the height of slag plate is higher than wastewater level.
Further, the mesh spacing of described upper screen pack is the mesh spacing being greater than lower screen pack.
Beneficial effect of the present invention is:
The present invention arranges inclined shaft in sewage conduct junction, and the both sides of inclined shaft are provided with draw-in groove, and scarfing cinder net both sides are connected in draw-in groove, and the sewage that such sewage conduct is come can go up screen pack and lower filter screen filtration, reduces blocking; The cross section of upper screen pack becomes w shape, convex stupefied towards inflow direction in the middle part of it, convex stupefied both sides, middle part are recessed to form accumulated slag portion backward, convex stupefied position, middle part can not form dregs extruding under the washing away of current, thus maintenance filter effect, gravelstone sublayer, activated carbon layer can be adsorbed filtering foreign, ensure that the quality of water.
Detailed description of the invention
Slagging-off net in a kind of blow-off line, the top of blow-off line is provided with water inlet, the bottom of blow-off line is provided with delivery port, inwall is provided with screen pack and lower screen pack, upper screen pack is connected by screen pack handle, the cross section of upper screen pack becomes w shape, convex stupefied towards inflow direction in the middle part of it, convex stupefied both sides, middle part are recessed to form accumulated slag portion backward, the screen pack handle junction of sewage conduct is provided with inclined shaft, inclined shaft tilts to inflow direction, the both sides of inclined shaft are provided with draw-in groove, lower screen pack is identical with the gradient of draw-in groove, screen pack handle both sides are connected in draw-in groove, activated carbon layer is fixed in the middle and lower part of upper screen pack, gravelstone sublayer is fixed in the middle and upper part of lower screen pack, gravelstone sublayer by clamp connection on blowdown tube wall.
