Abstract
The utility model belongs to an environmental protection facility, which is a non free water separating device in the sludge. The utility model comprises a mixing kettle, and the middle of the mixing kettle is vertically provided with a mixing oar, and the mixing oar is formed by a connecting rod and a blade, and the upper end of the connecting rod is connected with a drive, and the lower end of the connecting rod is connected with the blade. The mixing oar makes the motor drive the connecting rod to make the blade mix the sludge in the mixing kettle, and the powder coal ash, the steel ball or the glass ball have the friction effect during mixing. The utility model can make the non free water in the waste water and sludge in the city, the river-way and the lake sludge, which is of a simple structure with high glue water efficiency and low energy consumption.
Description
Technical field
The utility model belongs to a kind of environmental protection equipment, is specifically related to a kind of device that unfree water in the mud is broken away from.
Background technology
Municipal sewage treatment is built up in each city, the whole nation and is put into operation; this has played active effect to the water pollution problems that prevents China; but the mud that forms in the sewage treatment process has brought environmental pollution again; therefore aspect the protection environment, the processing of municipal sludge is become a problem of needing solution badly again.The method of disposal of mud mainly contains soil utilization, landfill, burning, biochemical treatment and topples over and throw sea etc. at present.But the moisture percentage in sewage sludge height that in sewage treatment process, is produced, volume is big, and this brings great inconvenience for its transportation, ultimate disposal and utilization, therefore must utilize sludge dewatering, exsiccant means, and moisture is separated from mud.Practice shows that the free water in the mud removes easily, but contains a large amount of microorganisms in the mud, contain a large amount of unfree waters in the microbial cell, this part unfree water remove difficulty, when general device breaks away from this part free water, energy consumption height, cost height.
The utility model content
The purpose of this utility model is to overcome above-mentioned technical obstacle, and unfree water separation device in a kind of simple in structure, energy consumption is little, cost is low mud is provided.
The utility model is achieved in that unfree water separation device in a kind of mud, the intermediate vertical of stirring tank is provided with stirring rake, stirring rake is made up of connecting rod and blade, the upper end of connecting rod connects driving mechanism, the lower end of connecting rod connects blade, stirring rake stirs blade by the electric motor driving connecting rod to mud in stirring tank, under churned mechanically effect, pass through friction contact between friction agent and the mud, destroy mud molecule and micelle thereof, reach the purpose that removes thereby make unfree water in the mud infiltrate.
The exit of described stirring tank can be equipped with the sieve plate of perforate.
The blade of described stirring rake can be at least 2.
Driving mechanism can be motor.
Motor can be alternating current machine.
Motor can be direct-current machine.
Compare with technology is arranged mutually, thus the utility model since the alr mode that adopts machinery down and friction agent under the frictional force effect, destroy mud molecule micelle with mud in unfree water remove, obtain effect preferably.Have dehydration energy consumption height, characteristics that cost is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the perforate synoptic diagram of the utility model sieve plate.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in detail.
As shown in Figure 1, the utility model is made up of stirring tank 1, blade 7, connecting rod 3, motor 4, sieve plate 6.Stirring tank 1 is provided with opening for feed 2, discharge port 5.The centre of stirring tank 1 is equipped with stirring rake, is used for mud is stirred.Stirring rake is made up of connecting rod 3 and blade 7.Connecting rod 3 upper ends connect driving mechanism, are generally motor 4.The connecting rod lower end connects blade 7, and the quantity of general blade 7 is 3 leaves.The rotation of blade 7 is rotated by motor 4 drivening rods 3, blade 7 is stirred mud in stirring tank 1, thereby the unfree water in the mud is removed.The exit of stirring tank 1 is equipped with the sieve plate or the filter cloth 6 of perforate, its perforate as shown in Figure 2, the hole of filter cloth is littler.
The dewatering of unfree water is as follows in the mud: mud and flyash enter stirring tank by opening for feed, rotation drive mud and flyash by stirring rake in stirring tank carry out mixed friction, in the friction process in the mud microorganism cells destroyed, unfree water contained in the microorganism is removed, when whipping process can be discharged it after 5-10 minute.Before the stirring tank discharge port, mud and flyash are through a sieve plate, and by this sieve plate, fine grain mud and flyash are discharged, and coarse grained flyash continues to carry out the agitating friction auxiliary agent at stirring tank as mud.
In the above-mentioned dewatering, generally use flyash, reach changing waste into resources, save cost as stirring auxiliary agent.In addition, can also adopt metal steel ball or granulated glass sphere.If use flyash as stirring auxiliary agent, the sieve plate order is several to be determined according to processing requirement.When adopting metal steel ball or granulated glass sphere to mix auxiliary agent, the aperture of sieve plate must be less than the diameter of metal steel ball or granulated glass sphere.
