Abstract
The invention discloses an anti-spill sludge filtering and squeezing dewatering belt. A lower belt is formed by a lower squeezing belt and a lower filtering belt which are mutually sleeved, and an upper belt is formed by an upper filtering belt and an upper squeezing belt which are mutually sleeved. The lower belt and a roll shaft are in matching transmission, and the two sides of the upward face of the lower filtering belt in the lower belt are provided with edge sealing belts along the length direction. An opening cavity formed by the edge sealing belts and the lower filtering belt is used for accommodating sludge to be dewatered. When the lower belt and the upper belt which are in transmission cooperation to carry out sludge dewatering, the lower belt and the upper belt simultaneously clamp the edge sealing belts at the two sides, and the clamped edge sealing belts are deformed along with the increase in the clamping force of the filtered and squeezed sludge. The pressed sludge is plugged by the edge sealing belts at the two sides and can not spill over, therefore, the pressure applied to the sludge is increased, the drainage and decompression of the pressed sludge are accelerated, and the purpose of effectively dewatering is achieved. Water filtered out from the sludge is drained from through holes which are uniformly distributed on the surfaces of the upper filtering belt and lower filtering belt. The anti-spill sludge filtering and squeezing dewatering belt has a simple anti-spill structure and is reliably sealed, so that the production efficiency of filtering and squeezing sludge is improved, and the dryness of sludge cakes are improved simultaneously.
Description
Technical field
The present invention relates to a kind of dewatering bands, specifically, the present invention relates to a kind of filter press for extracting juice dewatering bands that stops the excessive structure of mud that is provided with.
Background technology
Inevitable residual mud after sewage work disposes of sewage, the mud that from settling tank, comes out clearly is many because of water cut, in the pasty state.The sludge volume of pasty state is big, and both difficulty was deposited, also inconvenience transportation, more be unfavorable for follow-up recycling.In order further to reduce the water cut of mud, adopt dehydration equipment to make sludge dewatering treatment usually in the engineering.The belt filter pressing dehydrator is to use maximum a kind ofly in the existing device for dehydrating sladge waste, and this kind equipment can effectively dewater, but dehydration rate is not high, and the sludge cake water cut of being produced does not still reach the mass dryness fraction condition that recycling sludge utilizes about 80%.Now, mud reduces discharging has become one of sewage work's difficult point problem.Transition band is the key part of belt filter pressing dehydrator, and its performance quality directly influences dewatering rate.The transition band of prior art is a two dimensional structure, and its xsect is a rectangle, and pasty state mud bulk property is poor, is prone to excessively from both sides during roll shaft spreading that the mud that is placed in one is matched, and a small amount of remaining mud is by normal spreading dehydration.The transition band of two dimensional structure is taken pasty state mud ability in, is the subject matter of restriction belt filter pressing dehydrator production efficiency, does not solve the excessive problem of mud, just can not improve dewatering efficiency, can not effectively improve the mass dryness fraction of sludge cake.
Summary of the invention
The present invention is primarily aimed at a large amount of excessive deficiencies of existing slab construction transition band mud in pressure-filtering process, proposes a kind of flowover-proof type mud filter and presses dewatering bands.On the transition band of this structure in the district is pressed in filter edge bonding belt is set, clamps edge bonding belt by the transition band of two synchrodrive up and down, excessive to stop behind the mud pressurized, greatly improve mud filter press for extracting juice dewatering efficiency.
The present invention realizes technical object through following technical proposals.
It is flexible circumferential that dewatering bands is pressed in flowover-proof type mud filter, and it is nested with following transition band by the following expelling belt of dull and stereotyped band structure and sets up band down jointly, and the last transition band that is similarly the flat rubber belting structure is nested to set up jointly upward with last expelling belt and is with.Said going up on transition band and the following transition band zone face is uniformly distributed with through hole.Its improvements are: length direction is provided with whippy edge bonding belt along both sides between the following band of the superimposed transmission of support roll shaft and the last band.
Edge bonding belt in the said structure is a tubular member, makes with the rubber material.The edge bonding belt xsect is processed circular rings and is had good structural elasticity and elastic properties of materials, and edge bonding belt is along with the filter power that squeezes of sludge dewatering increases and is out of shape.It is straight-flanked ring, trilateral ring and special-shaped ring that edge bonding belt also can be made into xsect, as long as have elastic deformability's body, can both lean on mutually with the sealing of transition band up and down after the distortion, excessive when stoping pasty state mud to be pressed.
The present invention compared with prior art has following positively effect:
1, the tubulose edge bonding belt is simple in structure, easy to manufacture;
2, transition band folds edge bonding belt up and down, reliable installation, and the anti-overflow ability is strong;
3, edge bonding belt is an elastomerics, and both anti-overflow did not influence pasty state mud yet and filtered and press dehydration;
4, pasty state mud to be drained off is not excessive, effectively improves filter and presses production efficiency.

Fig. 1 is a lateral cross section structural representation of the present invention.
Embodiment
According to accompanying drawing and combine embodiment, the present invention is described further below.
It is a kind of flexible circumferential that dewatering bands is pressed in flowover-proof type mud shown in Figure 1 filter, and it is nested with following transition band 2 by the following expelling belt 1 of dull and stereotyped band structure and sets up band down jointly, and the last transition band 3 that is similarly dull and stereotyped band structure is nested to set up jointly upward with last expelling belt 4 and is with.Be uniformly distributed with through hole A on last transition band 3 and following transition band 2 zone faces.Following band directly cooperates transmission with roll shaft 7, and the following transition band 2 in the following band is provided with edge bonding belt 6 in the one side both sides up along its length.The spacious chamber of being made up of edge bonding belt 6 and following filtration 2 holds mud to be drained off, and the following band of transmission cooperates with last band when doing pasty state sludge dewatering, clamps the edge bonding belt 6 on both sides synchronously, and the edge bonding belt 6 that is pressed from both sides along with the feasible quilt of clamping force increase of filtering press for extracting juice mud is out of shape thereupon.The pasty state mud of pressurized can not be excessive by 6 shutoff of both sides edge bonding belt, increases the pressure to pasty state mud thus, and the pasty state mud of pressurized then quickens the draining decompression, thereby reach the purpose of high-efficiency dehydration.The water that leaches in the pasty state mud is from last transition band 3, the through hole A that is uniformly distributed with of transition band 2 zone faces discharges down.Edge bonding belt 6 adopts the rubber materials to process the pipe shape in the present embodiment, and play band folds the sealed structure that forms band edge with last band, and filter does not take place excessive when pressing pasty state mud, and the production efficiency that makes filter press mud improves, and the while is also improved the mass dryness fraction index after the sludge dewatering.
