Description

The lamination cunning leaches well

The utility model relates to a kind of equipment of Separation of Solid and Liquid filtered water.

Over the past thousands of years, filtration is the conventional method that Separation of Solid and Liquid is handled water.Filtration must be used screen pack, filter membrane or filtrate, and screen pack, filter membrane and filtrate all are consumable materials, can not reuse, and is usually blocked when filtering, and liquid outlet quantity is reduced, and usually needs clearly net, changes filter membrane, changes filtrate.Device for dehydrating sladge waste has four kinds substantially: 1, vacuum filter, 2, plate and frame filter press, 3, belt filter press, 4, horizontal spiral centrifuge.First three kind all be unable to do without filter screen, and filter cycle is long, and the 4th kind exists the energy consumption height, and noise is big, the problem that dewatering efficiency is low.Municipal sewage plant's sewage disposal operation is to enter aeration tank, oxidation ditch behind grid, the desilting, enters second pond then, and floor space is big, the processing time is long, cost of water treatment is more than the running water height.

The purpose of this utility model is to propose a kind of brand-new lamination cunning to leach well, makes the Separation of Solid and Liquid filter efficiency higher, and the worry that does not have network blocking, changes film, reloads shortens treatment time of water greatly, reduces the floor space and the cost of sewage disposal of sewage treatment plant.

The technical scheme that the utility model lamination cunning leaches well is:

Slide relatively and the slip filtering surface that is staggeredly distributed with the limbers is formed one group of sliding filter unit by two maintenances, with the gap between two slip filtering surfaces is the drainage gap, the sliding of annular more than a group filtered cells overlap together, form lamination shape slip screened well, with slide filtering surface group and even number slip filtering surface group drives respectively or fixing of odd number, form stator group and moving plate group, the stator group is fixed on along in the vertical guide-track groove that is provided with of well depth, the moving plate group is driven by the drive unit that is located at well heart end, is connected with the pusher arm that promotes the motion of moving plate group on the driving shaft of drive unit.

Above-mentioned pusher arm is located at the driving shaft two ends, connects the pushing piece roller bearing between two pusher arms.

End between the above-mentioned stator is placed with cushion block.

The internal diameter of above-mentioned moving plate group is less than the internal diameter of stator group, and the external diameter of moving plate group is equal to or greater than the external diameter of stator group.

Can be provided with flocculant on the above-mentioned guide-track groove and outpour pipe.

The utility model lamination cunning leaches the principle and the course of work of well: two maintenances are slided relatively and the slip filtering surface that is staggeredly distributed with the limbers is formed one group of sliding filter unit, sewage leaches from the drainage gap, become clear water through sliding filter unit to opposite side, automatically cleaning is stopped up, filtrate is attached to the surface of sliding filter unit, can blow off with mechanical means, also can come off by deadweight.The machining accuracy of the sliding filtering surface of control and contact tightness degree can be regulated " mesh ", as long as slide filter unit speed of related movement greater than sludge blockage speed, clear water will continue to flow out.Having under the situation of pressure differential, the speed of water outlet can be accelerated with the increase of pressure differential.A plurality of drainages gap of lamination shape slip filtering surface, so water yield is big.When rotating under the driving of center rotating shaft at drive unit, pusher arm drives roller bearing and promotes the motion of moving plate group under the drive of central rotating shaft, and the lamination cunning leaches well sewage and filters through the drainage gap between the sliding filtering surface, clear water flows out from delivery port, and mud takes out through the mud mouth not timing.The lamination cunning leaches in the second pond or concentration basin that well can be located at sewage treatment plant, add a spot of flocculant, all substances except that liquid can be stopped, only discharge water and dissolved matter go out, pollutional load is alleviated greatly, through the clear water after the sliding filter from water outlet and in complete from top to bottom degree of depth water outlet, accelerated water speed greatly, this just means area and the volume that dwindles second pond greatly, do not need to wait the great circle pond build tens rice diameters, do not need to wait the circle basin irrigation is completely later water outlet again when supernatant occurring yet.Because the also water outlet simultaneously of wet well bottom, this will significantly improve the solids content of concentrate.

Advantage of the present invention is: the slip filter method has proposed sliding filter new ideas, and the efficient of Separation of Solid and Liquid filter method is improved greatly, and the worry that does not have network blocking, changes film, reloads has realized filtering without net.Be applicable to from sludge dewatering to the membrane filtration, the water treatment of molecular filtration.The lamination cunning leaches well shortens the sewage disposal time of municipal sewage plant greatly, significantly reduces the floor space and the processing cost of sewage treatment plant.The universal condition of having created for sewage treatment plant.Also can be applicable to trade effluents such as mining industry, coal, cement building material handles.
