Description

The high-effective sewage purifying device

The utility model relates to a kind of sewage purification device, specifically be a kind of sewage that will contain a large amount of solid suspensions separate, be cleaned into mud and water purification device.

Existing sewage purification device has two kinds of pressure type integral water cleaner and high turbidity clarifiers, their structure is basic identical, by the top top cover, three parts of middle part tank body and bottom hopper dredger are formed, clear water discharge pipe and blast pipe are arranged on top cover, be provided with filter head plate in the tank body, be filter material layer below, dendritic pipe is arranged in the middle of the filter material layer, below cylindrical collection mud tube bottom a bit of for taper, be several water pipes on every side, the bottom of passing the taper whirl cylinder communicates with hopper dredger, down be taper whirl cylinder and cylindrical whirl cylinder again, cylindrical whirl cylinder passes from annular hopper dredger center, to the tank body outside, this section is revolved movably filter screen is housed in the tube that drips, the sealing of whirl cylinder bottom, the bottom is the sewage water inlet pipe that tangentially is connected with cylindrical whirl cylinder, below taper eddy flow nozzle, an annular collector pipe is arranged, be connected to straight tube and pass outside the tank body, join with the forced refluence pipe in the tank body outside, the upper end of return duct is connected with the person in charge of dendritic pipe, at annular hopper dredger inner bottom part annular sludge pipe is arranged, and reaches outside the hopper dredger by straight-run of pipe, be discharge pipeline, the entire sewage clarifier is fixed on the basis by four cylinders that are welded on the tank body.The shortcoming of this type of sewage purification device is: 1. need to fill with clear water when starting, be unsuitable for using in the place that does not have enough clear water source; 2. mud need collect mud and discharges through endless tube, is unsuitable for the big mud of viscosity, also is unfavorable for further reducing moisture percentage in sewage sludge; 3. the mud alumen ustum that proportion is bigger has the phenomenon of part toward the whirl cylinder sedimentation because sinking speed is fast, influences treatment effeciency; 4. the sewage below the filter material layer all is in the eddy flow state in tank body, and less alumen ustum is difficult to sedimentation, increases the load of filtering layer, and backwash is more frequent, influences treatment effeciency.

The purpose of this utility model is: a kind of high-effective sewage purifying device is provided, and the sewage treating efficiency height of this clarifier, discharge of sewage foot, moisture percentage in sewage sludge are low, clear water can discharge simultaneously with mud, and can long-time continuous move.

The technical solution of the utility model is: a kind of high-effective sewage purifying device, comprise the loam cake, middle cylinder, the bottom sludge bin that are provided with clear water discharge pipe and backwash water inlet pipe, the top of described middle cylinder is provided with exhaust filter pipe, screen pack, water fender from top to bottom successively; The middle part of described middle cylinder is provided with top flare, the cylindrical whirl cylinder in bottom, and being with in the whirl cylinder is top flare, bottom cylindrical collection mud tube equally, and sewage water inlet pipe is from tangentially entering the bottom of whirl cylinder; Described bottom sludge bin is tapered, and the bottom is connected with the mud discharge pipe.

The further technical scheme of the utility model is: a kind of high-effective sewage purifying device, comprise the loam cake, middle cylinder, the bottom sludge bin that are provided with clear water discharge pipe and backwash water inlet pipe, the top of described middle cylinder is provided with exhaust filter pipe, screen pack, water fender from top to bottom successively; The middle part of described middle cylinder is provided with top flare, the cylindrical whirl cylinder in bottom, and being with in the whirl cylinder is top flare, bottom cylindrical collection mud tube equally, and sewage water inlet pipe is from tangentially entering the bottom of whirl cylinder; Described bottom sludge bin is tapered, and the bottom is connected with the mud discharge pipe; The outside of described middle cylinder is provided with return duct, and the upper end of return duct is communicated with exhaust filter pipe, the lower end is communicated with the both sides of whirl cylinder; The periphery of described bottom sludge bin is provided with the cylindrical lower portion cylindrical shell.

The utility model has the advantages that:

1. the current that the screen pack of collection mud tube top and water fender can make rotation rise in the utility model stop the rotation, and become the current of rising, thereby make less alumen ustum also can precipitate discharge downwards.

2. the utility model top that will collect the mud tube changes horn mouth into, and combines with whirl cylinder, and circling water flow rate is increased, and most mud alumen ustum can enter hopper dredger with recirculation water, have improved treatment effeciency.

3. the utility model has adopted the taper sludge bin, and mud is directly discharged by the mud discharge pipe of bottom, and the mud of bottom can access better and concentrates under the gravity effect of the mud on top and water, makes the moisture percentage in sewage sludge of discharge lower.

4. the utility model is simple in structure, has alleviated the resistance that clear water makes progress, and has accelerated separating rate, and mud need not regularly discharge, and can discharge simultaneously with clear water, and can the long-time continuous operation.

The utility model will be further described below in conjunction with drawings and Examples:

Fig. 1 is a structural representation of the present utility model;

Wherein: 1 clear water discharge pipe; 2 backwash water inlet pipes; 3 loam cakes; 4 middle cylinders; 5 exhaust filter pipes; 6 bottom sludge bin; 7 screen packs; 8 water fenders; 9 whirl cylinders; 10 collection mud tubes; 11 sewage water inlet pipes; 12 mud discharge pipes; 13 return ducts; 14 bottom cylindrical shells.

Embodiment: as shown in the figure, a kind of high-effective sewage purifying device, comprise the loam cake [3], middle cylinder [4], the bottom sludge bin [5] that are provided with clear water discharge pipe [1] and backwash water inlet pipe [2], the top of described middle cylinder [4] is provided with exhaust filter pipe [6], screen pack [7], water fender [8] from top to bottom successively; The middle part of described middle cylinder [4] is provided with top flare, the cylindrical whirl cylinder in bottom [9], being with in the whirl cylinder [9] is top flare, bottom cylindrical collection mud tube [10] equally, and sewage water inlet pipe [11] is from tangentially entering the bottom of whirl cylinder [9]; The outside of described middle cylinder [4] is provided with return duct [13], and the upper end of return duct [13] is communicated with exhaust filter pipe [6], the lower end is communicated with the both sides of whirl cylinder [9]; Described bottom sludge bin [5] is tapered, and the bottom is connected with mud discharge pipe [12]; The periphery of described bottom sludge bin [5] is provided with cylindrical lower portion cylindrical shell [14].

Technological process of the present utility model is: sewage adds medicament before processing, and sewage is sent into sewage water inlet pipe by sewage pump, enter water purifier again, colourity in medicament and the sewage and a large amount of organic matters combine therebetween, forming the mud alumen ustum fast enters in the water purifier, sewage tangentially enters whirl cylinder, under pressure and action of centrifugal force, the mud alumen ustum enters collection mud tube and sinks, because the organic matter of materialization sewage is more heavy than the ratio of water, quicken down through top pressure condition, enter sludge bin fast, and clear water makes progress away after separating, because the proportion of clear water is lighter than organic matter, behind pressure, the clear water upward velocity is accelerated.

Operation principle of the present utility model is: the pressure that produces when utilizing sewage to enter and from habit power, in whirl cylinder, rotate, clear water is made progress away discharges by the clear water drainpipe, mud in collection mud tube downwards precipitation enter sludge bin and discharge.
