Abstract

The utility model relates to a spiral bulk type fluidized screening device which is used for treating complicated material and particularly is used for treating urban refuse. A screening water tank (2) is provided with a spiral drum screen (3) which is provided with internal threads (4), and the cylinder wall of the spiral drum screen (3) is acted as a screen surface. The spiral drum screen rotates and drives refuse. One side of the spiral drum screen forwards pushes, and the other side of the spiral drum screen screens. The screened object becomes fluid and flows out. The screened and left object automatically is divided into floats floated on the water and sinks sunk to the bottom of the screen. The floats and the sinks are respectively outputted by two conveying belts (10) (9) which are vertically crossed along the propelling of the threads. The utility model is suitable for treating obsolete materials with large quantity and complicated ingredient, such as refuse, etc. The utility model has the advantages of less investment, high work efficiency, categorized recovery, large treatment quantity and continuous operation.

Description

Fluidized screening device with spiral drum screen

The utility model belongs to the screening washing facility, is used to handle the solid material of complicated component, especially for the device of handling municipal refuse.

Existing screening plant (as horizontal screen, drum sieve etc.) can sorting purer material (as ore, vegetable seeds etc.); A spot of material existing washing facility (as washing machine) can wash (as clothing etc.).For composition complexity, quantity material (as municipal refuse) how, existing screening, washing facility are powerless.

The purpose of this utility model just provides the particularly treating apparatus of municipal refuse of solid material that a kind of confession handles the composition complexity in a large number, and can come out according to the characteristics classifying screen of rubbish so that recycle, small investment, and treating capacity is big, and program is simple.

The purpose of this utility model reaches by following scheme: have a top that faucet, overfall are arranged, the tank of agitating auger slurry and apopore is arranged at the bottom, in tank, crouch adorn one have internal thread, barrel is covered with the cylindrical shape spiral rotary screen of sieve aperture, the discharging opening of spiral rotary screen has two conveyer belts of upper and lower grade separation.

The embodiment that provides below in conjunction with accompanying drawing further introduces the content of utility model:

Fig. 1 is the utility model plane (vertical view);

Fig. 2 is the front view (partial cutaway) of tank and helix drum screen sections in the utility model;

Fig. 3 is an A-A cutaway view among Fig. 1;

Fig. 4 is a B-B cutaway view among Fig. 1.

As shown in drawings, the right-hand member of spiral rotary screen (3) has charging aperture (1), and left end has discharging opening (8), and hypostasis conveyer belt (9) and floating thing conveyer belt (10) are arranged before the discharging opening.Tank (2) bottom is useful on the screw (11) of stirring below rotary screen (3), bottom of gullet has osculum (6).All there is certain gradient the bottom of tank so that screenings is discharged to osculum (6) with water to the osculum direction.Cylinder spiral rotary screen (3) is crouched by cylinder roller (13) supporting and is contained in the tank with the power driven rotary, barrel is covered with sieve aperture (5), internal thread in the spiral rotary screen (3) is used for carrying is is while stirring sieved and washed material, internal thread (4) is higher, and flank generally is welded on the inwall with steel plate forming.For making the charging aperture continuous feed, reinforced available conveyer belt transmits; For ease of into and out of material, the internal thread at rotary screen two ends generally should adopt involute shape (12).There is the upper and lower grade separation that is of floating thing conveyer belt (10) and hypostasis conveyer belt (9) to arrange before the discharging opening of spiral rotary screen.Floating thing such as floating on the water paper, plastics, bamboo wood chip is exported by floating thing conveyer belt (10) after spiral rotary screen (3) tails over; Weights such as stone, brick and tile, glass and metal are exported by hypostasis conveyer belt (9).The going out dried up and locate all to have tap (14) the flushing output that discharges water of two conveyer belts, this water flows into the sieve and wash water of tank as spiral rotary screen.Screenings after sieving and washing is a fine grained, enters the sedimentation basin fermentation can be used as organic fertilizer and use after osculum (6) is discharged becoming fluid under the stirring of screw (11) in water.The restricted overfall (7) of sieving and washing water level in the top of tank.

Progressive effect of the present utility model and advantage:

One, the utility model is particularly suitable for processing discarded object, municipal refuse can be become the clean raw material of industry and become farmland organic fertilizer easy to use to reclaim. All refuses all utilize, and have both processed municipal refuse, can obtain enormous wealth from reclaim again;

Two, continuous productive process, treating capacity is big, and the work efficiency height is particularly suitable for processing the municipal refuse that pile up like a mountain;

Three, use the utility model to handle municipal refuse, cost is low, small investment, and last detective is particularly suitable for China's national situation;

With Shanghai City daily output rubbish is example for 40000 tons, and the utility model technology is as shown in the table with " burning method " technological investment economic benefits indicator:

	Plant layout (day output)	Investment	The technique device number	Gross investment	Throwing volume ratio
						Waste incineration factory technology	300 ton per days	4,310 ten thousand yuan/	133	5,732,300,000 yuan	358
The utility model device technique	1000 ton per days	400,000 yuan/	40	1,600 ten thousand yuan	1

Four, it is few to use the utility model to handle the municipal refuse secondary pollution, compares with landfill, compost treatment rubbish method, does not fall into disuse the soil.
