Abstract

The invention relates to a sludge cleaning machine, which consists of a primary filter (1), a water inlet pipe (2), a settling tank (3), a water outlet filter screen (4), a water outlet pipe (5), a self-priming pump (6), a water spray pipe (7), a detachable reverse spray nozzle (8) and a sludge discharge outlet (9). The working principle lies in that: under the effect of the self-priming pump, sewage is preliminarily filtered by the primary filter (1) and enters the settling tank (3) through the water inlet pipe (2), substances such as mud, sand and the like with large specific gravity are settled in the settling tank, and the sewage enters the water outlet pipe (5), the self-priming pump (6) and the water spray pipe (7) through the filter screen (4) and then is sprayed by the detachable reverse spray nozzle (8). When sludge, biogas residues and the like in the settling tank are accumulated to a certain quantity, the self-priming pump is reversely connected, and water is filled into the settling tank; the sludge discharge outlet (9) is opened, and the water inlet pipe (2) is blocked; and under the pressurization effect of a water pump, the sludge, the biogas residues and the like are discharged through the sludge discharge outlet.

Description

Dredger

1. technical field: this dredger is the machinery that is used to clear up sewer mud and cleaning biogas scum liquid.On a little bases, improve the construction that can be used for bridge pier, pile tube for building and well-digging a little and from the underground machinery of taking out sand.

2. background technology: because China's building science is started late; The sewer design in longer building of some ages and city is very unreasonable; Basically all silt up terribly now, had a strong impact on resident's life and city water drainage, also normal some social concerns that cause.So be badly in need of a kind of equipment-dredger that can clear up sewer mud.And present already used dredging sewer machine is powerless to sediments such as ducted mud.

Popularizing of production and use of marsh gas engineering, but the waste residue of cleaning biomass pool has become problem.Though the instrument of many cleanings natural pond slag has been arranged now, separate owing to can not realize slag liquid, can only connect slag liquid and transport together, effect is very undesirable.

This dredger produces for addressing the above problem.

3. summary of the invention: the characteristics of this dredger are: the one, and repeated multiple times is utilized waste water work.With waste water sediment is drawn in the settling tank; With waste water sediment is flushed near the pipeline intake; Reaction force with the current of contra-injection is guided to the sewer depths with sparge pipe.The 2nd, the waste water that is being mingled with sediment and floating thing be introduced into the settling tank deposition and filter after just get in the self priming pump, avoided the damage of sand, twister to water pump, guaranteed the operate as normal of water pump.

4. description of drawings: this dredger by coarse filtration head (1) inlet channel (2) settling tank (3) go out detachable reverse shower nozzle (8) row of water screen (4) outlet conduit (5) self priming pump (6) sparge pipe (7) become silted up mouthful (9) form.Its operating principle is: under the effect of self priming pump; Sewage in coarse filtration head (1) simple filtration after inlet channel (2) get in the settling tank (3); The material that proportions such as silt are bigger precipitates in settling box, and sewage is sprayed by detachable contra-injection head (8) through filter screen (4) entering outlet conduit (5) and self priming pump (6) sparge pipe (7).When mud in the settling tank or natural pond slag etc. run up to some, again self priming pump is oppositely inserted water filling in settling tank.The row of opening becomes silted up mouthful (9), blocks inlet channel (2).Depress in adding of water pump, mud or natural pond slag etc. are through row's silt mouthful discharge.For looser material such as sand, natural pond slag in the jar, need not oppositely insert water pump pressurization also smoothly outside the drain tank, only need the row of opening silt mouth (9) just.

5. the specific embodiment: this dredger be utilize in the sewer and biomass pool in waste water work.When clearing up long sewer, adopt detachable oppositely shower nozzle.This shower nozzle utilizes reaction force to bring sparge pipe into sewer than the depths at when work water spray backward in the other direction, has solved longly all to advance not go the difficult problem that deposit cannot be cleared up apart from sewer machinery and people.Can also be through the artificial outwards action of pull repeatedly, the sediment water is flushed to the position of sewer well head, again in suction water pipe is drawn into settling tank.Also having sewage is to be introduced into settling tank just to get in the water pump after filtering, has avoided sand, twister to get in the water pump, has guaranteed the operate as normal of water pump, has improved the operating efficiency of water pump.

When clearing up the deposit in the biomass pool, can not use the contra-injection head.

This device also can be fixedly mounted on the vehicle, uses the motor on the vehicle that operation power is provided.

Claims

1. this dredger is to realize repeatedly cycle repeats utilization of water; And with the machinery of current work; Going out detachable reverse shower nozzle (8) the row silt of water screen (4) outlet conduit (5) self priming pump (6) sparge pipe (7) mouthful (9) by coarse filtration head (1) inlet channel (2) settling tank (3) forms; Its operating principle is: under the effect of self priming pump, after inlet channel (2) gets in the settling tank (3), the material that proportions such as silt are bigger precipitates in settling box sewage in coarse filtration head (1) simple filtration; Sewage gets into outlet conduit (5) and detachable contra-injection head (8) ejection of self priming pump (6) sparge pipe (7) through filter screen (4), accomplishes the circulation of primary water.

Such as right petition article one statement, the detachable contra-injection head that this dredger adopts, this detachable contra-injection head in use the angle of injection direction and the pipeline of water between zero degree to eight ten is spent.

Such as right petition article one statement, the row of this dredger is become silted up mouthful below settling tank.

Such as right petition article one statement, this dredger is established the coarse filtration head at the water inlet pipe road junction, the object that prevents to block pipeline gets in the pipeline.
