Detailed description of the invention
Accompanying drawing discloses the structural representation of preferred embodiment involved in the present invention without limitation; Technical scheme of the present invention is explained below with reference to accompanying drawing.
As shown in Figure 1, a kind of sludge filtering pressing dehydrator, containing underframe 1, supporting cell guide 5, machine footstock 7, oil cylinder 8, upper pressure seat 6, down pressing seat 4, press filtration car, filter press plate, filter press cloth 11 and jacking apparatus 3.Supporting cell guide 5 is arranged on the middle part of underframe 1, machine footstock 7 is arranged on the top of supporting cell guide 5, oil cylinder 8 is arranged on machine footstock 7, upper pressure seat 6 is arranged on the piston rod 9 of oil cylinder 8, down pressing seat 4 is arranged on jacking apparatus 3, and this jacking apparatus 3 is arranged on underframe 1, underframe 1 is provided with guide rail 2.Press filtration car is made up of bearing plate 12 and wheel 13, and wheel 13 is arranged on bearing plate 12, and wheel 13 is positioned on guide rail 2.Described filter press plate 10 comprises upper surface 15 and lower surface 16, and as shown in Figures 2 and 3, upper surface 15 is provided with several annular grooves 14, and each annular groove 14 interlinks with adjacent cylindrical groove 14.Due to several annular grooves 14 on filter press plate 10 upper surface 15, each annular groove 14 interlinks with adjacent cylindrical groove 14, so not only can in extrusion process, prevent stress from concentrating and cause the problem that filter press plate 10 damages, and the resistance to sliding that can increase filter press cloth 11, be conducive to filtering press-dehydrating.Experiment shows, if the upper surface of filter press plate 10 15 is smooth plane, not only filter press-dehydrating uneven, and filter press plate 10 easily damages; If the upper surface 15 of filter press plate 10 is provided with several rectangle grooves, and several rectangle grooves each and adjacent rectangle groove interlink, such filter press plate 10 is concentrated because the junction between rectangle groove easily produces stress in extrusion process, thus causes the damage of filter press plate 10.For improving dewatering efficiency, the lower surface 16 of described filter press plate 10 is provided with several annular grooves, and each annular groove and adjacent cylindrical groove interlink.Several annular grooves that the lower surface 16 of described filter press plate 10 is provided with and described upper surface 15 are provided with several annular grooves 14 and are staggeredly arranged in position, as shown in Figure 2.The external diameter that the upper surface 15 of described filter press plate 10 and lower surface 16 are provided with some individual annular grooves 14 is 40 to 80 millimeters, internal diameter is 32 to 65 millimeters, and the degree of depth of annular groove 14 is 3.5 to 8 millimeters, and described filter press plate 10 is 25 to 45 millimeters.Described filter press plate 10 is made up of nylon material.When using above-mentioned sludge filtering pressing dehydrator, first one piece of filter press plate 11 is placed on the bearing plate 12 of press filtration car, then material frame for subsequent use is placed on filter press plate 10, again the mid portion of filter press cloth 11 is laid in material frame, then by water content be 80% mud put into material frame filter press cloth 11 on, then the remainder of filter press cloth 11 is wrapped on mud, repeat above-mentioned operation procedure, make heap on the bearing plate 12 of press filtration car have some filter press plates 10, and between adjacent two filter press plates 10, be all placed with the filter press cloth 11 being surrounded by dirty filter.Press filtration car 2 moves to above down pressing seat 4 on guide rail, down pressing seat 4 is upwards pushed up and is moved by jacking apparatus 3, make wheel 13 getaway 2 of press filtration car, at this moment oil cylinder 8 drives upper pressure seat 6 to move down by piston rod 9, extrude the some filter press plates 10 be positioned in down pressing seat 4, through reaching the extruding of a period of time, the water content of the mud in the filter press cloth 10 between adjacent two filter press plates 10 lower than 30%, thus overcome prior art cannot be by water content 80% sludge dewatering to water content be the mud of less than 30%.Last jacking apparatus 3 moves down, and the wheel 13 of press filtration car is positioned at guide rail 2, and oil cylinder 8 drives piston rod 9 to make upper pressure seat 6 is moved back into original position simultaneously, and press filtration car is drawn out, and successively takes off mud in filter press cloth 11.Test shows, when suitable intensified pressure and extrusion time, can be that sludge dewatering to the water content of 80% is the mud of less than 25% by water content.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to right.
