Description
Technical field
The present invention relates to a kind of sludge treatment device, particularly relate to a kind of piston-type filter.
Background technology
People's door produces sewage and mud, contaminated environment in production and life process.Country advocates energetically and preserves the ecological environment.In the technical requirement of Treatment of Sludge, one is had to be that its moisture content must lower than 60%.At present conventional sludge drier is plate compression formula, and drying type two kinds, but plate and frame type filter-press, take a lot of work, and time-consuming, moisture content is higher, and the dry function of drying type solves moisture content completely compared with high problem but energy consumption is large.
Utility model content
The purpose of this utility model is to provide a kind of piston-type filter, this filter is arranged in the piston of cylinder piston rod lower end, when piston enters in press filtration cylinder, under the pressure effect of piston, in press filtration cylinder, the fluid (gas and sewage) in mud is flowed to pressure lower by pressure eminence, and flows out press filtration cylinder by piston-type filter delivery pipe, solid matter in mud is subject to filter cloth cover to be stopped and stays in press filtration cylinder, effectively reduces moisture content in mud.
A kind of piston-type filter, this filter is arranged in the sleeve-like piston of cylinder putter lower end.This filter bottom is provided with filter, and the equal level of filter upper surface, lower surface is provided with the network structure of the linear type groove composition communicated in length and breadth, and filter inside is provided with the through hole of through upper surface, lower surface, can conducting upper surface, lower surface groove.The coated one deck filter cloth of filter lower surface, fits tightly with lower surface and fixes.
Further, dividing plate is provided with above filter upper surface, dividing plate is connected with piston inner wall, dividing plate top is the load framework of vertical gusset composition, the lower partition is provided with the press filtration chamber of cavity structure as gathering ground, each press filtration chamber is at least across the groove of more than two, and upper opening place, press filtration chamber is provided with the delivery pipe extending to piston exterior.
Further, described upper surface, lower surface are also distributed with multiple ring-shaped groove equably, and described ring-shaped groove is by mutual for adjacent linear type groove conducting.
Further, be provided with retainer plate filter cloth is closely fixed on filter lower surface.Retainer plate and piston inner wall compact siro spinning technology, stop that mud oozes out from piston inner wall.
Further, described retainer plate by the mode of clip by tight for filter cloth clip on filter.
Further, the lower surface of filter cloth is provided with bottom plate, the uniform through hole of bottom plate.
Further, described bottom plate is screwed in piston bottom surface,
To work as piston enters in press filtration cylinder, under the pressure effect of piston, fluid (gas and sewage) in press filtration cylinder in mud is flowed to pressure lower by pressure eminence, by the through hole that bottom plate is uniform, because filter cloth can make the fluid in mud (gas and sewage) pass through, stop that the solid matter in mud passes through.Therefore fluid covers into filter through filter cloth, and the through hole on filter upwards flows out, and is flowed to the lower partition press filtration chamber, through delivery pipe, the fluid (gas and sewage) in mud is discharged press filtration cylinder.Solid matter in mud is subject to filter cloth cover to be stopped and stays in press filtration cylinder.Filter area due to filter is large and drainage runoff is many, and its drainage, ventilation efficiency are higher, speed, and after press filtration completes, air can enter in press filtration cylinder fast, eliminates vacuum effect and negative pressure, can improve work efficiency, reduces energy consumption.
The utility model has the advantage of: structure is simple, the filter area due to filter is large and drainage runoff is many, and its drainage, ventilation efficiency are higher, speed, can improve work efficiency, reduces energy consumption, is suitable for automation electric operation, improves work efficiency.Its drainage Be very effective, is better than plate and frame type filter-press plate.Use the pressure-filteration drying machine of piston-type filter, moisture percentage in sewage sludge can be made lower than 60%.

Detailed description of the invention
With reference to figure 1, a kind of piston-type filter, this filter is arranged in the sleeve-like piston 1 of cylinder putter lower end.This filter bottom is provided with filter 5.
With reference to figure 3,4, filter 5 upper surface 52, lower surface 53 all level are provided with the network structure of linear type groove 56 composition communicated in length and breadth, filter 5 inside is provided with the through hole 55 of through upper surface 52, lower surface 53, can conducting upper surface 52, lower surface 53 groove 56.Described upper surface 52, lower surface 53 are also distributed with multiple ring-shaped groove 51 equably, and described ring-shaped groove 51 is by the conducting mutually of adjacent linear type groove 56.
With reference to figure 5,6, the coated one deck filter cloth 9 of filter 5 lower surface 55, fits tightly with lower surface 55, retainer plate 7 by filter cloth 9 closely clip on filter 5.Retainer plate 7 and piston 1 inwall compact siro spinning technology, stop that mud 6 oozes out from piston 1 inwall.The lower surface of filter cloth 9 is provided with bottom plate 10, fixes, the uniform through hole of bottom plate 10 with screw 8 and piston bottom surface.Be provided with dividing plate 4 above filter 5 upper surface 52, dividing plate 4 top is the load framework (not drawing in Fig. 5,1) of vertical gusset composition, and dividing plate 4 has welded with piston 1 inwall strengthens structure function.Dividing plate 4 bottom is provided with the press filtration chamber 41 of cavity structure as gathering ground, and each press filtration chamber 41 is at least across the groove 56 of more than two, and upper opening place, press filtration chamber 41 is provided with the delivery pipe 2 extending to piston 1 outside.
With reference to figure 2, to work as piston 1 enters in press filtration cylinder 3, under the pressure effect of piston 1, fluid (gas and sewage) in press filtration cylinder 3 in mud 6 is flowed to pressure lower by pressure eminence, by the through hole that bottom plate 10 is uniform, because filter cloth 9 can make the fluid in mud 6 (gas and sewage) pass through, stop that the solid matter in mud 6 passes through.Therefore fluid enters filter 5 through filter cloth cover 9, and the through hole 55 on filter 5 upwards flows out, and is flowed to press filtration chamber, dividing plate 4 bottom 41, through delivery pipe 2, the fluid (gas and sewage) in mud 6 is discharged press filtration cylinder 3.Solid matter in mud 6 is subject to filter cloth cover to be stopped and stays in press filtration cylinder 3.Filter area due to filter 5 is large and drainage runoff is many, and its drainage, ventilation efficiency are higher, speed, and after press filtration completes, air can enter in press filtration cylinder fast, eliminates vacuum effect and negative pressure, can improve work efficiency, reduces energy consumption.
