Description

A kind of sewage is automatically pumped wet mixing soil and is reclaimed screening machine and using method thereof

Technical field

The invention belongs to water-bearing concreae recovery technology field, be specifically related to a kind of sewage and automatically pump wet mixing soil recovery screening machine and using method thereof.

Background technology

Concrete refers to makes Binder Materials with cement, and sand, masonry gather materials; Coordinate by a certain percentage with water, through stirring, shaping, maintenance and the cement concrete that obtains, concrete is the material of architectural extensive use.

Along with the extensive use of commerical ready-mixed concrete, commodity are concrete produces a large amount of waste residues, waste water simultaneously in production for Cement Concrete Mixing.The main source of these slag and effluents is: the cleaning emission of the concrete production such as mixing plant, trucd mixer, pump truck and the unnecessary order of engineering and discarded concrete.Because these waste water and waste residue all have strong basicity, pH value can reach about 12, and containing insoluble matters such as a large amount of cement, sandstone, if do not processed, discharges arbitrarily, will bring disaster to irrigation and water conservancy, and blocking urban operating mechanism, has a strong impact on environment.

Because country, to the demand of the environmental requirement of Concrete Enterprises and enterprise self, therefore, needs to reclaim concrete.

Current concrete recycle sewage disposal system mainly reclaims the residual concrete after the cleaning of the remaining concrete of concrete mixing plant, concrete transport vehicle, concrete mixer and stirring host, and the common problem of the water-bearing concreae sandstone separation waste water recovery system of current home and abroad is as follows:

1. the screening machine in the wet concrete recovering system of current home and abroad is all use overfall to overflow sewage in screening machine.Sewage concrete is down to automobile-washing groove, go to rinse the concrete in automobile-washing groove with the water pump of 3kW to 4.5kW again, concrete is rushed in screening machine, just start screening process, the water source that the water pump of 3kW to 4.5kW is rushed out and tank car the brought water source that adds water defines inflow as huge flood, inflow as this huge flood flows into screening machine, at once just again from the spilling as the sewage overflow mouth flood outside screening machine, this just causes being difficult to water to be separated with sand, cause in cesspool and contain a large amount of sands, be unfavorable for the later use of sewage.

2. be also provided with the water pump that is rinsed screen cloth in the screening machine had at screen cloth place, add equipment investment.

3. huge inflow, although be finally back to cesspool, and the mode such as carwash, jet-bedding can be adopted to recycle, but also do not solve the problem of automatically cleaning neatly of automobile-washing groove and screen cloth completely, still need labor cleaning's automobile-washing groove and screen cloth.

4. huge inflow overflows screening machine, the fine sand of very high content can be brought into cesspool.

5., because the screen cloth of existing screening machine sewage overflow mouth is fixing position, be easy to, by sand, building fiber clogs, overfall to be cleared up every day.

6. do not arrange screen cloth inside the water-bearing concreae screening machine producer screening machine had, sandstone are unified utilizes helical blade to scrape outside screening machine.When building stones adopt helical blade to scrape this mode of screening machine, during screening machine idle running, enter a little sand material and can not there is what problem, once screening machine has entered building stones, just start the electric current affecting screening machine drive motors, because building stones are easy to the helical blade of stuck screening machine, often cause stuck problem, drive motors can be burnt time serious, even if not stuck, building stones transporting resistance also can be caused large, and then cause the starting current of drive motors large, the problems such as voltage instability pressure, power consumption is large.

7. the motor of screening machine is arranged on axle head, general comparatively large of the inner bag volume of screening machine, drives to be arranged on center axle head and to run gruelling, and required reducing motor power is comparatively large, comparatively power consumption.

8. the administrative staff of mixing plant have strong comments to the power consumption of international and domestic wet concrete recovering system, because lose more than gain, the concrete value namely reclaimed does not support the value of institute's consumes power far away.According to the head of a station of a mixing plant, a set of concrete recycle sewage disposal system, if one day does not have carwash, equipment keeps being energized for 24 hours again, and whole system must run again for 24 hours incessantly, gets off like this, wet concrete recovering system just will expend upper 1000 degree of electricity every day, when being busy with one's work, the continuous carwash of meeting, power consumption in a day more than 4000 is spent.The value of the sandstone material that concrete recycle sewage disposal system cleans out is less than the odd expending electricity and be worth.

Sewage pumps the using method that wet mixing soil reclaims screening machine automatically, includes following steps:

A. charging: add the sewage of wet mixing soil and flushing wet mixing soil in automobile-washing groove after, wet mixing soil concentrates at the bottom of automobile-washing groove automatically, sewage enters screening machine, than high bottom screening machine bottom automobile-washing groove, after sewage in screening machine exceeds 500mm height, the same with the water level bottom automobile-washing groove, sewage has flooded the water-bearing concreae in automobile-washing groove;

B. conveying is stirred in advance: the flexible helical feed of water-bearing concreae, the basal diameter of the flexible conveyor screw blade of water-bearing concreae is little, end face diameter large, and tilt upward convey materials, discharging opening is also lower than charging aperture, material is naturally transformed in order to high in and low out, carries water-bearing concreae material;

C. sewage transport: send water helix tube to tilt upward and transport the sewage come from the extraction of spiral sewage pumping device, when screening machine runs, spiral sewage pumping device is followed and is sent water helix tube to rotate, sewage natural enter spiral sewage pumping device from pumping device water inlet, enter the inside sending water helix tube from pumping device delivery port;

D. sewage and sand material and building stones screening: when screening machine runs, the rotation sending water helix tube followed by fine sand filter screen washer, sewage is along sewage transport helical blade, through the fine sand filter screen washer water inlet of each part fine sand filter screen washer, have fine sand will leak material mouth from fine sand filter screen washer fine sand to spill, leak on screen cloth, while filtering fine sand, also have water to go out, rinse screen cloth, fine sand filter screen washer fine sand leaks the sewage that material mouth has not leaked, and continues to flow out along sewage transport helical blade to send outside the pipe of water helix tube;

E. building stones and sand material screening: the concrete that screening machine splicing conveyor screw blade transports, fall on the screen cloth of screening system, follow in the rotating operation of screening machine by screening helical blade, under sewage cleaning in screening machine, sand material drops down onto in screening machine shell from screen cloth sieve, water-bearing concreae sand material, building stones, be separated with cement after, screening helical blade continues the building stones of conveying on screen cloth, and the sand material that sieve falls continues to carry outside screening machine by sand material scraping delivery helical blade; Sieved the building stones after the sand material of water-bearing concreae by screening helical blade, be delivered to building stones conveyor screw blade, building stones conveyor screw blade can keep building stones at the discharging opening of screening system frame, goes out building stones more stably;

F. sand material conveying: by sand material scraping delivery helical blade, be delivered to the sand material of sand material discharging opening, by anti-path sand material scraper helical blade, scrapes screening machine sand material and specifies in blow tank sand material blow tank.

invention course:the present invention lasts more than 1 year, the present inventor has abundant working experience at concrete mixing plant, so have clear and definite understanding to the shortcoming of modern concrete recovery system, screening system between current wet concrete recovering system both domestic and external is all the sewage that use overfall overflows in screening machine, a large amount of water resources is needed to go to rinse, sand can be made to be separated with sewage not exclusively, need manually to go to clear up overfall, so the present inventor just expects inventing a kind of automatic cleaning equipment and can be separated the recovery screening serial equipment of the water-bearing concreae of sewage and sand and stone completely.

Inspiration of the present invention is at first from conveying worm.Wherein many-sided art-recognized meanings be unableing to do without helix tube, has the sewage as flood to overflow from overfall, although there is overfall screen cloth to intercept in present screening machine.Sewage as flood can develop sand material in screening machine.Want to change this situation.What first the present invention expected carries sewage to go out screening machine by helical feed mode exactly, is exactly sewage water sending device spiral sewage water feeder of the present invention.The central point of the spiral sewage water feeder helical blade that the present inventor considers at first has axle, advance step by step along with of the present invention, just arranging its helical blade is afterwards that basal diameter is large, and end face diameter is little, and the cut surface of its helical blade remains the height of cut surface unanimous between the higher and lower levels.After and then expect fine sand filter screen washer, but being combined and just having no idea to combine with current any screening machine both domestic and external at all of these two inventions.Its can not in conjunction with reason be have no idea to be drawn into the sewage of position minimum in screening machine, at this moment, the present invention encounters first bottleneck, having taken long a period of time does not all break through, until once see the steel ring on bicycle and steel wire, suddenly inspiration has been carried out, the technology of waterwheel is dug ancient times in conjunction with us, first it is envisioned that semicircular pumping device, wiper blade is dug as waterwheel, that just can not excavate water minimum in river just, afterwards along with continuous propelling of the present invention, take into account and the ideal that profile of the present invention should tilt upward the results contrast of conveying is set.According to the technical requirement sending water system device to tilt upward of the present invention, the semicircular hydrophone that digs of feeling at that time can use reluctantly, but I am not to semicircular pumping device feeling quite pleased always, the pumping device that panesthesia is more suitable for than semicircular pumping device in addition.Considered that multiple angles was to install semicircular pumping device at that time, namely 90 degree of right angles should be formed from the installation with spiral sewage water feeder exactly, or the installation at the oblique angle of 45 degree should be kept more suitable, or should install more than 90 degree of right angles, or be arranged on angle on spiral sewage water feeder shell along with the change at the angle of inclination of spiral sewage water feeder designs semicircular pumping device.Wherein also considered a lot close to semicircular pumping device, considered use triangle, square pipe etc.Through me to continuous propelling of the present invention, to the further understanding of spiral aspect, when the external appearance characteristic that spiral sewage water feeder tilts upward, contemplate and be adapted at most tilting upward, the most suitable pumping device excavating sewage in extraction screening machine, should be just only have the pipeline of use spiral path, the present invention that Here it is extracts the helical pattern sewage digging type pumping device of sewage in screening machine.When its helical pattern sewage digging type pumping device is arranged on the extraction sewage of the shell of the sewage water feeder tilted upward, extract the sewage in screening machine than semicircular pumping device, its sewage transport angle is more smooth and easy.Its spiral path sewage digging type pumping device just need not go consideration should use which type of angle to have installed again when being installed on spiral sewage water feeder, when helical pattern sewage digging type pumping device is installed to spiral sewage water feeder shell, as long as just use the angle with spiral sewage water feeder is same to install.Contemplating helical pattern pipeline to after extracting the sewage in screening machine, extract technically not breaching again of sewage excavating, namely do not go again to consider to have or not better excavate sewage in screening machine dig hydrophone.

The present invention has had sewage transport helical blade, fine sand filter screen washer, helical pattern sewage digging type pumping device, and the present inventor just starts there has been confidence to wet concrete recovering system package unit.Sewage transport helical blade of the present invention, fine sand filter screen washer, spiral sewage dig hydrophone, and very difficult combination to be arranged on inside current any wet concrete recovering system screening machine both domestic and external and to play a role.Reason is the profile of spiral sewage water feeder of the present invention, its sewage outlet pipe, sewage outlet, must at the central point of screening machine, so the present invention encounters second time bottleneck.

According to distinctive basic outward appearance, the feature of spiral sewage water feeder of the present invention, fine sand filter screen washer, spiral sewage excavation pattern pumping device, the present inventor starts to arrange screening plant.

The present invention just expects using by screening system outer casing stand at the beginning, and screening spiral conveying blade, screen cloth, 4, sand material scraping delivery blade forms, and the blank of screening system of the present invention is the huge problem had very at the beginning.Subject matter appears at sand material discharging opening and building stones discharging opening two parts exactly.A spiral sewage water feeder has been installed in screening machine centre of the present invention.The sand material discharging opening of the blank of the restriction screening system of the present invention of its profile and all super large of building stones discharging opening, large to the stage that client should do not had to accept.Here be exactly second time bottleneck of the present invention.

The present inventor contemplated the sand material discharging opening in screening system blank of the present invention afterwards, then arranged a set of anti-path sand material scraper helical blade, and control the blow tank that sand material is being specified, discharging opening goes out sand material.Arranging the number of building stones conveyor screw blade in the present invention is (32) building stones conveyor screw blade, the helical blade bottom surface overall diameter arranged is 1060mm, bottom surface interior diameter is 860mm, end face overall diameter is 800mm, end face interior diameter is 740mm, helical cut face thickness 5mm to 10mm, the spiral number of turns 1.1 are enclosed, helix length 1100mm, pitch are 1000mm, the cut surface 100mm of building stones conveyor screw blade feed end (41), vane thickness 5mm; The cut surface 30mm to 50mm of building stones conveyor screw blade discharge end (42), vane thickness 5mm; Annular array 2; Controlling building stones can keep building stones to go out building stones in the lowermost portion position of building stones discharging opening substantially.Screening system of the present invention is just calculated and can be employed.Just almost breach to second time bottleneck of the present invention in this time.The present inventor has huge confidence to the present invention.

The time of huge confidence is had, time namely the third time of the present inventor runs into bottleneck, time namely the present inventor advances the most difficult for the present invention the present inventor.Wherein wanted to use a lot of method to do the feed system of screening machine of the present invention.Be attached among screening system of the present invention, there is no the use of the suitable the present invention of the feed system of that family's screening machine.The feed system of its other screening system is improper is arranged on the reason that screening system of the present invention does feed system, is because central point has installed spiral sewage water feeder of the present invention in screening machine of the present invention.Its problem is exactly mainly appear at charging, and with screening machine splicing, I does not find and am applicable to doing feed system of the present invention, but other mode in use.The screening machine enclosure bottom diameter that the present inventor is arranged is 2200mm, arranges sewage of the present invention and send the base diameter of water spiral case to be 900mm to 1000mm.The position diameter 2000mm that the bottommost of its screening system frame screen cloth installation site is maximum, sand material conveyor screw blade has been installed in the outside of its screening system frame, screening helical blade has been installed in the inner side of its screening system frame, the interior diameter of its screening helical blade is 1800mm, its the present invention arrange the interior diameter of screening helical blade and the bottom external diameter maximum of spiral sewage water feeder of the present invention only had about 400mm spacing, its 400mm, the feed pipe that the place of spacing is arranged also wants certain spacing can not collide with screening machine system.Its present invention designs the design tilted upward.The design tilted upward, the interior diameter of screening helical blade arranged in its present invention of the present invention and the bottom external diameter maximum of spiral sewage water feeder of the present invention have only had about 400mm.The free space tilted upward is just less, and ratio is said, the present invention uses the feed pipe of a 300mm diameter, go deep into end and go deep into, in screening machine of the present invention, also will keeping some spacing, can not collide with this screening system frame.When the non-helical conveying of pipeline, the angle that must maintain under being tilted to just can feeding.Enter the position of the spacing 400mm of screening system of the present invention.If when under screening machine is tilted to, the pipeline installing 300mm can go deep into, and does not touch shell, but the screening system tilted upward, and the spacing of its 400mm can go deep into charging feed pipe, just contrary having diminished of retainable spacing.This third time runs into bottleneck and has perplexed me for a long time.Spend good long a period of time, contemplated and use spiral to carry.Contemplate again and use spiral to carry the water-bearing concreae containing building stones to be very undesirable.Its reason is that normal spiral is easy to stuck helical blade.Again afterwards long after, contemplate and use bottom surface diameter little, end face diameter is large, and the water-bearing concreae containing building stones carried by the spiral of taper.The screw feed en-trance of taper is little, and discharging opening is large.Should be just to carry the water-bearing concreae containing building stones very easily.Until the present inventor contemplates the conveying charging of use flexible conveyor screw and arranges a base diameter in the bottom of screening system frame less, top diameter and screening system frame uniform diameters, the charging material receiving tube docked with screening system frame, the inside of charging material receiving tube, install splicing conveyor screw blade again, the talent of the present invention have passed third time of the present invention bottleneck thoroughly.Complete the design of whole system.

(3) beneficial effect:

1. can reducing when carwash draws water rinses automobile-washing groove, and material can focus on automatically bottom automobile-washing groove and be delivered into screening machine, and carwash rinses without jet-bedding pumping for water pump, and automobile-washing groove also can be kept inside and outside clean.

2. adopt the flexible feed auger charging of water-bearing concreae, when spiral inclination upwards convey materials, in general helical feed material is upwards being carried by low, the flexible feed auger of water-bearing concreae of the present invention, basal diameter little end face diameter is large, tilt upward convey materials, the water-bearing concreae of full packages, in the conveying of water-bearing concreae accommodation conveying charging helical blade, after water-bearing concreae has been transported to the discharging opening of flexible conveying feed auger, just become half materials in the tube, the water-bearing concreae of smaller part materials in the tube, water-bearing concreae is also lower than charging aperture at spiral discharging mouth, material is naturally just transformed into the transport model in order to high in and low out, carry water-bearing concreae material, water-bearing concreae can be carried easily, the mode of movement of letting nature take its course.

3. employing spiral sewage pumping device extracts the sewage in water-bearing concreae recovery screening machine, the sewage of lowest water level in screening machine can be drawn into, the sewage being applicable to any water level in screening machine extracts, sewage in water-bearing concreae screening machine uses overfall to overflow sewage and has no idea to control the sewage overflow outflow water yield, time chance screening machine inflow is large, the sewage of overfall overflow is too slow, meet in screening machine and also have water-bearing concreae not sieve totally, time in screening machine, water inlet is few, inadequate sewage will be caused to go to clean water-bearing concreae, screening machine is when carwash, sometimes two tank cars, even 3 tank cars fall sewage simultaneously and enter in screening machine, use overflow manner, the sewage water yield of super large, also can sand material huge for content in sewage to going out screening machine, the mode that extracts employing water pump extracts the sewage in water-bearing concreae screening machine, in water pump does not allow there is sewage in screening machine, continuous print goes to extract the sewage in screening machine, indirectly extract also undesirable, use overflow and water pump, overflow cleans water-bearing concreae with existing enough suitable sewage in all uncontrollable screening machine of extraction, control sewage can not diffuse out the problem outside screening machine again, spiral sewage pumping device is adopted to extract the sewage that water-bearing concreae reclaims screening machine, both can control in screening machine, there are enough sewage cleaning water-bearing concreaes, can accomplish that again the sewage in screening machine can not be crossed too full, screening machine tilts upward, spiral sewage pumping device spiral path is installed 30-60 part and is being sent on water helix tube, wastewater level in screening machine is high, sewage in screening machine can be excavated, spiral sewage pumping device will be many, extracting sewage rapidly exactly, the low spiral sewage pumping device being drawn into sewage in screening machine that can excavate of wastewater level in screening machine will lack, be exactly at extraction sewage slowly, employing spiral sewage pumping device extracts the sewage in water-bearing concreae recovery screening machine, the sewage being applicable to any water level in screening machine extracts, meet strong then strong.Meet weak then weak.

4. adopt spiral sewage water feeder conveying sewage to go out outside screening plant, can carry and adopt spiral sewage pumping device to extract the sewage in water-bearing concreae recovery screening machine, the pumping device of other profile same is pumped the sewage come and can be transferred out too outside screening machine, midway outside screening machine can be gone out to fine sand filter screen washer at conveying sewage, filter fine sand, screen cloth cleans, and provides favourable time and chance.

5. adopt fine sand filter screen washer, without pumping for water pump cleaning screen cloth, also can reach the effect of screen cloth cleaning.Effectively can reach sewage, the effect be separated with sand.Fine sand is avoided to go out outside screening machine, avoid sewage to go out screening machine and do the program that second filters fine sand outward again, the effect that its fine sand filters and screen cloth cleans and effect follow the discharging opening parameter change of fine sand filter screen washer, and quantity changes effect and changes thereupon, with strong then strong.

6. adopt anti-path sand material scraper helical blade, sand material scraping delivery helical blade can be controlled and scrape any discharge hole for discharge sent the sand material of going outside screening machine and specifying.

7. adopt building stones conveyor screw blade, building stones can be kept to transfer out the outer building stones minimum position discharging remaining on discharging opening always of screening machine.The effect of that material at discharging opening blanking of non-helical conveying discharging maintenance can be arrived.
