Description

Solid-liquid separating machine

The utility model relates to a kind of solid-liquid separating machine, can be widely used in the physical treatments of industry to solid and fluid separation applications such as mine industry, steel and iron industry, leather industry, fermented soy industry, paper industry, sugar industry and city B-grade sewage factory.

China's like product mainly contains thickener, chamber filter press, disc vacuum filter, band extruder or the like at present, but have three big problems not have all the time thoroughly to solve: the one, the filtrate of discharging can not directly be discharged by body, discharging reluctantly after major part adopts sedimentation basin or adds the chemical agent precipitation process.The 2nd, from going into to expect that the whole courses of work of the satisfactory filtrate of discharging can not be continuous.The 3rd, think that system's floor space is big, factory building and equipment investment are too high, and power consumption is big, uses inconvenient maintenance.

The purpose of this utility model provides a kind of solid-liquid separating machine, and equipment is finished separating of solid and liquid, and can work continuously, and investment and floor space are little.

The purpose of this utility model realizes as follows: this solid-liquid separating machine has feeding mouth on its airtight body, at internal body Filter column is set, the solid discharging opening is arranged at the bottom of body, in the body outside filtrate tanks is set also and stores the clean liquid of blowback, on filtrate tanks, be provided with and be attached thereto logical back-blowing device, connect clean liquid pipe in the outlet of back-blowing device, on the top cover of body, be set communicating pipe, the lower end of each communicating pipe links to each other with Filter column, be connected with discharging tube between the upper end of communicating pipe and the back-blowing device upper surface inlet, the most handy transparent pipe of discharging tube, be used to observe the clean level of liquid in pipe whether to determine the Filter column operate as normal, because Filter column and communicating pipe quantity more, and the negligible amounts that discharging tube can be arranged, connect a discharging tube after several communicating pipes are communicated with, on the solid discharging opening of body lower end device for discharging is set, this device for discharging can the discharging voluntarily by the pressure that detects solid material.

Have in the inner chamber of back-blowing device with power and be connected and rotatable hollow anti-blowpipe, outlet on the anti-blowpipe connecting lever can communicate with the inlet of back-blowing device upper surface, and the below of anti-blowpipe has suction pumps for the tail end that communicates with it and is inserted in pipette in the filtrate tanks inner chamber.This machine is when the Separation of Solid and Liquid course of work, if do not need to the Filter column blowback, all the inlet positions on the back-blowing device upper surface are avoided in the outlet of anti-blowpipe connecting lever, all Filter columns all participate in filtering, filtrate enters the back-blowing device inner chamber through discharging tube, makes filtrate tanks keep full liquid status and overflow to discharge through clean liquid pipe.When Filter column needs blowback, drive the anti-blowpipe rotation by power, outlet on the anti-blowpipe connecting lever communicates with the inlet of back-blowing device upper surface, by suction pumps imbibition from filtrate tanks, liquid enters into the discharging tube that communicates with this inlet through the anti-blowpipe connecting lever, the Filter column that communicates with this discharging tube is carried out blowback, and other Filter column still filters normally, so discontinuously the Filter column that is communicated with back-blowing device upper surface inlet is carried out blowback, and whole equipment is in the duty of Separation of Solid and Liquid all the time, guarantees the continuity of work.

Device for discharging is made of stator, rotor and power set.The stator of device for discharging is connected with the solid discharging opening of body, and rotor is made of several V-type grooves and is connected with power.During discharging, power drives the rotor rotation, and solid material falls into the V-type groove of rotor, leans on the gravity automatic blanking when this V-type groove forwards the outlet of device for discharging to.

If solid material needs to be squeezed to remove the liquid branch, on the discharging opening of device for discharging, be connected to pressurizing unit, this pressurizing unit can be roll form, can squeeze out the partially liq composition to solid material.

This Separation of Solid and Liquid function is worked continuously, small investment, and floor space is little, is used for the processing to liquid emission after many medium-sized and small enterprises have the ability to purchase fully, helps the development of environmental protection cause.

Below in conjunction with accompanying drawing the utility model is further described.

Accompanying drawing is the structural representation of the utility model solid-liquid separating machine.

With reference to accompanying drawing, on body 4, feeding mouth is arranged, feeding mouth is communicated with feed pump 1 by feeding pipe 3, on feeding pipe 3, be connected to Pressure gauge 2, communicating pipe 5 is set on the top cover of body 4, its lower end connects Filter column 6, the upper end is connected with discharging tube 7, filtrate tanks 9 in the annular of arranged outside of body 4, on filtrate tanks 9, be provided with and be attached thereto logical back-blowing device 8, the other end of discharging tube 7 is connected on the inlet of back-blowing device 8 upper surfaces, in the inner chamber of back-blowing device 8 is to be connected with power and rotatable hollow anti-blowpipe, and the below of anti-blowpipe has the pipette of suction pumps for the tail end that communicates with it, suction pumps is in the inner chamber of filtrate tanks 9, when anti-blowpipe rotated, the outlet of its connecting lever can communicate with the inlet of back-blowing device 8 upper surfaces, connects clean liquid pipe 12 in the outlet of back-blowing device 8.Be connected to device for discharging 10 on the solid discharging opening of body 4 lower ends, promptly the stator of device for discharging 10 is connected with the solid discharging opening, and its rotor is made of the V-type groove and is connected with power, is connected to pair roller type pressurizing unit 11 on the discharging opening of device for discharging 10.When carrying out Separation of Solid and Liquid work, enter body 4 inner chambers by feed pump 1 feeding through feeding pipe 3, liquid post 6 after filtration filters after tube connector 5 and discharging tube 7 enter back-blowing device 8 inner chambers, and partly clean then liquid enters filtrate tanks and is used for blowback, and all the other are discharged through clean liquid mouth 12.Solid then post precipitation increases when solid reaches a certain amount of back pressure by gravity fall, and device for discharging 10 and pressurizing unit 11 work are squeezed solid to remove liquid and divided the back discharge.In the time of need carrying out the blowback cleaning to Filter column 6, back-blowing device progressively carries out blowback to all Filter columns, and entire equipment keeps continuous duty.
