Abstract
The invention relates to a plate-frame pressure filtration dewatering machine for sludge dewatering equipment used in a sewage treatment plant, in particular to a filter plate for the dewatering machine. The invention aims to provide a novel filter plate for the dewatering machine, which can shorten the discharge route of pressure filtrate of a pressure filter, reduce liquid discharge resistance, realize quick discharge of pressure filtrate, reduce the dewatering time of the pressure filter and improve the dryness of the pressure filter sludge cakes. For fulfilling the aim, the invention adopts a technical scheme that the novel filter plate of the sludge dewatering machine is characterized that: the filter plate is formed by connecting front and rear plate bodies into a whole by circumferential parts; pores are distributed on at least one of the front and rear plate bodies; the pores are communicated with an empty cavity between the front and rear plate bodies; and the empty cavity are communicated with through holes formed on the edge of the plate body to form liquid discharge passages.
Description
Technical field
The present invention relates to the plate compression dewaterer of sludge of sewage treatment plant dehydration equipment, specifically is exactly the filter plate that uses on the dewaterer.
Background technology
At present domestic sludge dewatering treatment technology and the common plate and frame filter press in the equipment, diaphragm type plate and frame filter press and deeply dehydrating sludge filter press, in the process of mud, can press filtration go out a large amount of pressing filtering liquids by the lower mud cake of filter press dehydration back formation moisture content, and in present sludge press filtration dewaterer, the discharge of filtrate is only discharged by one or several aperture of monoblock filter plate bottom in the mud, and the plate face of so-called filter plate is plain plate face, the pressing filtering liquid that can form like this in the monoblock mud need overcome the longer route of mud and resistance discharge greatly, be unfavorable for the discharge of pressing filtering liquid in the mud, influence the mass dryness fraction of time of filter pressing and mud cake.
Summary of the invention
Purpose of the present invention just provides a kind of filter press pressing filtering liquid that can shorten and discharges route, reduces the discharge opeing resistance, the novel filter plate of sludge dewatering equipment of mud cake mass dryness fraction after can realizing discharging pressing filtering liquid fast, shorten the dewatering time of filter press and improving press filtration.
For achieving the above object, the present invention has adopted following technical scheme: the novel filter plate of a kind of sludge dewatering equipment, it is characterized in that: filter plate is connected as one along peripheral position by forward and backward plate body, be distributed with aperture at least one plate body in the forward and backward plate body, this aperture is communicated with cavity between the forward and backward plate body, and the through hole that is provided with on cavity and the plate body edge is communicated with and constitutes the discharge opeing path.
Be provided with during normal the use on the plate face of aperture and arrange filter cloth, mud is transported in the cavity between stripper plate and the filter cloth, stripper plate is driven to extruding of filter cloth one side and then extruding mud by actuating unit, moisture process filter cloth in the mud and aperture enter the cavity between the forward and backward plate body, and the through hole discharge opeing through being provided with on the plate body edge.Because aperture is to distribute to be arranged on the plate body, the mud in the sheet frame can be realized discharge opeing, leach from a plurality of apertures fast in pressurized process like this, and the liquid that leaches concentrates in the middle cavity of filter plate, and is discharged by the through hole that is provided with on the plate body edge.Mud pressing filtering liquid in pressure-filtering process can be discharged at nearest aperture, pressing filtering liquid short via the path, efflux time is short, the discharge opeing resistance is little, the mass dryness fraction of mud cake after can shortening the dewatering time of filter press and improving press filtration.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the local enlarged diagram of Fig. 1;
Fig. 4 is the local enlarged diagram of the present invention when using.
The specific embodiment
As Fig. 1,2, the novel filter plate of a kind of sludge dewatering equipment, filter plate 10 is connected as one along peripheral position by forward and backward plate body 11,12, be distributed with aperture 113 at least one plate body in the forward and backward plate body 11,12, this aperture is communicated with cavity 13 between the forward and backward plate body 11,12, and the through hole 14 that is provided with on cavity 13 and the plate body edge is communicated with and constitutes the discharge opeing path.During normal the use, through hole 14 should be placed into lowest part, to make things convenient for discharge opeing.
Aperture is provided with dual mode, all can be provided with on the plate face of promptly forward and backward plate body 11,12, and concrete scheme is exactly: evenly lay aperture 113 on the plate face of the preceding plate body 11 of the described filter plate 10 of the first, described cavity 13 is a strip; It two is evenly to lay aperture 113 on the plate face of forward and backward plate body 11,12 of described filter plate 10, and described cavity 13 is a strip.Preferred version is that described cavity 13 is the bar shaped cavity of netted layout.Like this, the filtrate in the mud is discharged from the shortest path, and less effectively flow resistance, dewatering time shorten greatly.
As shown in Figure 1, the inner and outer plates face of described preceding plate body 11 is concordant, and the peripheral position welding of groove 121, two plate bodys of the perforation that the outer panel face of rear plate body 12 is concordant, the interior plate face is provided with netted layout constitutes filter plate 10.This structure helps the independent processing of forward and backward plate body 11,12, and welding manner connects also very convenient realization, in addition, groove 121 constitutes the draining path, lug boss 122 between groove 121 and the groove 121 plays the effect of similar gusset, plate body is implemented supporting role, in conjunction with Fig. 3.We can say that also filter plate 10 is that Welding Structure is formed a kind of hollow double-deck filter plate.
The inner and outer plates face middle part large tracts of land of plate body 11 is concordant before described, the edge 111 of side plate face be basin along shape, this basin is positioned at the side at extrusion chamber A, B, C place along the edge 111 of shape, in conjunction with shown in Figure 4.
Shown in figure 1,4, described before plate body 11 middle parts offer through hole 112 UNICOM of aliging with the perforate at rear plate body 12 middle parts, through hole 112 makes things convenient for mud to inject with mud carrying path or pipeline connection, edge 111 has the effect that retrains mud of collecting.
Below in conjunction with description of drawings use principle of the present invention.
When sludge dewatering equipment when carrying out filter-press dehydration, cylinder thrust acts on the pressing plate 1, pressing plate 1 promotes piston plate 2 makes compression spring 3 produce compression, cavity A, B between the polylith filter plate of sludge dewatering, the mud in the C are squeezed, the filtrate that press filtration goes out is in time discharged from aperture 113 by filter cloth 5, the filtrate of discharging enters in the cavity 13 that is made of groove 121, discharges the drainage system that is delivered to outside the equipment through the through hole 14 of bottom again.
Like this, mud pressing filtering liquid in pressure-filtering process can be discharged at nearest aperture, and the pressing filtering liquid efflux time is short, the discharge opeing resistance is little, mud cake mass dryness fraction after can shortening the dewatering time of filter press and improving press filtration.
