Description
Technical field
The utility model relates to the device that a kind of filtrate that sludge vacuum filtration machine can be produced is discharged automatically, continuously, belongs to separation technology field.
Background technology
Sludge vacuum filtration machine is by the device of the filtering from water of the mud in high-concentration sewage, sludge vacuum filtration machine is generally connected in sequence by filter, gas water separation tank and vavuum pump, the negative pressure that vavuum pump produces makes sewage flow to gas water separation tank through filter, mud in sewage is inhaled on the filter cloth of filter, water, gas and a small amount of silt enter gas water separation tank through filter cloth, the gas entering gas water separation tank is inhaled into vavuum pump, and water and a small amount of silt are then stayed in gas water separation tank.
In order to enable equipment continuous service, the drainage in gas water separation tank needs constantly to discharge, but the negative pressure plumbing in gas water separation tank causes very large difficulty.At present, sludge vacuum filtration machine generally adopts automation case (see figure 1) to discharge drainage, after control system detects that gas water separation tank water is full, automatically opens blowoff valve and carries out draining, after drainage is drained, automatically close blowoff valve, wait for draining next time.But after opening blowoff valve, drainage can not be discharged immediately, only have when gas water separation tank extraneous air enters in tank, make in tank after pressure increase to atmospheric pressure, drainage could flow out.So not only destroy the subnormal ambient of vacuum filter inside, have impact on the normal operation of filter, but also the load of vavuum pump is increased suddenly, pump shaft shear stress suddenlys change, the off-axis caused thus, burning motor accident occur often, have had a strong impact on normally carrying out of production.
Utility model content
The purpose of this utility model is the drawback for prior art, provides a kind of vacuum filter self-draining arrangement, while guaranteeing that filter continues normal operation, reduces the fault rate of vavuum pump.
Problem described in the utility model realizes with following technical proposals:
A kind of vacuum filter self-draining arrangement, formation comprises gas water separation tank, transformation pipe and surge tank, described gas water separation tank is positioned at the top of surge tank, its air inlet is connected with vacuum filter by intake valve, exhaust outlet is connected with vavuum pump by air bleeding valve, and the upper end of described transformation pipe is connected with the discharge outlet of gas-water separation pot bottom, and lower end to be inserted in the middle part of surge tank and is tightly connected with the tank skin of surge tank, the bottom of described surge tank is provided with blowoff valve, and side wall upper part is provided with gap.
Above-mentioned vacuum filter self-draining arrangement, the air inlet of described gas water separation tank is positioned at the middle and lower part of tank body, exhaust outlet is positioned at the top of tank body, and the inwall of gas water separation tank is provided with the baffle plate of inclination, and described baffle plate is between the air inlet and exhaust outlet of gas water separation tank.
Above-mentioned vacuum filter self-draining arrangement, the gap of described surge tank and the difference in height of gas-water separation pot bottom are less than or equal to 10 meters; The inside of surge tank, the volume of height part between gap and transformation pipe lower end is not less than the volume of transformation pipe inside.
The external and internal pressure that the pressure that the utility model utilizes the drainage in transformation pipe to produce carrys out Balance Air water separation tank is poor, gas water separation tank is made to maintain the unobstructed of drainage channel when keeping original negative pressure, not only achieve continuous drainage, and the normal operation of filter and vavuum pump can also be guaranteed, reduce the fault rate of equipment.
The utility model scheme that possesses skills is scientific and reasonable, and simple structure is practical, does not need the features such as maintenance, is applicable to the various place needing vacuum dehydration.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the structural representation of traditional vacuum filter drainage arrangement (automation case);
Fig. 2 is structural representation of the present utility model.
In figure, mark is as follows: 1, intake valve, and 2, air bleeding valve, 3, baffle plate, 4, gas water separation tank, 5, transformation pipe, 6, gap, 7, surge tank, 8, blowoff valve, 9, control system.
Detailed description of the invention
Referring to Fig. 2, the utility model comprise intake valve 1, air bleeding valve 2, baffle plate 3, gas water separation tank 4, transformation pipe 5, with the surge tank 7 of gap 6 and blowoff valve 8.
Utility model works principle:
(1) when vacuum filter runs, water, gas and a small amount of silt are inhaled into gas water separation tank 4, larger water droplet, mud pellet directly to drop on bottom gas water separation tank 4 and flow into transformation pipe 5, and mist droplet mud pellet is also removed through baffle plate 3 collision rift major part and flows into transformation pipe 5.Baffle plate 3 has constant slope, to guarantee that mud does not deposit on baffle plate 3.
(2) transformation pipe 5 has certain (vertically) height H, need to calculate according to the size of negative pressure in gas water separation tank 4, otherwise water will be inhaled into vavuum pump, and production cannot normally be carried out during design.When equipment runs, because there is negative pressure in gas water separation tank 4, in transformation pipe 5, be sucked up the water column of certain altitude, the height h of water column
1depend on the size of vacuum in transformation pipe 5, that is determined by vavuum pump, but the vacuum that vavuum pump produces is never more than an atmospheric water-column.Therefore the height H of transformation pipe 5 is less than or equal to 10 meters.
(3), before vacuum filter starts, first surge tank 7 water-filling should be given, in case extraneous air enters gas water separation tank 4 through surge tank 7 and transformation pipe 5.After device start, along with the foundation of gas water separation tank 4 internal negative pressure, the water in surge tank 7 is inhaled into transformation pipe 5, and the drainage that filter produces afterwards also flows into transformation pipe 5, the water-column h in transformation pipe 5
1change with the change of vacuum in gas water separation tank 4, when transformation pipe 5 is without any obstruction, water-column=vacuum.The water entering gas water separation tank 4 not cracked ends transformation pipe 5 flows in surge tank 7, and flows out (pressure of gap is atmospheric pressure, and relative pressure is zero) from gap 6, this process is continuous print, in transformation pipe 5, liquid level keeps constant substantially, and surge tank water level is also constant, unnecessary spilling.This device, while realizing continuous drainage, can stop extraneous air to enter, and ensures that filter internal negative pressure is constant.
(4) during blowdown, open blowoff valve 8 and the silt bottom surge tank is discharged, but must control of sewage disposal flow, prevent surge tank water level too low and affect the sealing of gas water separation tank 4, certain water yield can be supplemented to surge tank if desired.
