Detailed Description

The invention is further described with reference to the accompanying drawings and the detailed description below:

as shown in fig. 2 to 6, the strong pressure pump suction type sludge dewatering machine comprises a conveying draining device 1 and a water extruding device 2 which are communicated with each other in a front-back mode, wherein sludge 3 which is initially driven in falls on the conveying draining device 1 firstly, and falls on an inlet of the water extruding device 2 from an outlet of the conveying draining device 1 after natural draining.

The extrusion water outlet device 2 is provided with two mesh belts 4, sludge 3 is clamped between the two mesh belts 4, the extrusion water outlet device 2 is provided with two primary rollers 5 and 5 secondary rollers, and the sludge 3 is extruded at the two primary rollers 5 and the 5 secondary rollers to be discharged.

5 secondary cylinder include one be located the preceding position cylinder 8 in the place ahead, two little cylinders 7 and two big cylinders 6, little cylinder 7 stagger the distribution from top to bottom with big cylinder 6 and big cylinder 6 is located the below of little cylinder 7, and the vertical distance b between the center of little cylinder 7 and big cylinder 6 is 45 ~ 55cm, through increaseing this vertical distance for it is better to go out water effect.

The mesh belt 4 between the small roller 7 and the large roller 6 is vertical, the vertical mesh belt 4 is easier to discharge water, and meanwhile, the wrapping and winding area of the large roller 6 and the small roller 7 on the mesh belt 4 reaches 60% -70% of the surface area of the mesh belt 4, so that the arrangement of increasing the wrapping area of the mesh belt 4 and promoting the vertical water discharge of the mesh belt 4 is favorable for improving the dewatering performance of the whole machine.

Every 6 big cylinders on the cladding guipure 4 department support to press have two to press to pump the device, every pass presses to pump the length of device and surpasss half of the width of guipure 4 and two pass and press to pump the device front and back stagger, make single pressure cylinder 13 quality lighter (the pressure cylinder 13 length is shorter) like this, can place more quantity of pressure cylinder 13, can guarantee that whole guipure 4 all can extrude simultaneously, can not leave the dead angle that can not extrude.

The high pressure pumping means comprises a push plate 9 driven by pneumatic means 14 to move up and down, the pneumatic means 14 pushing the push plate 9 and the high pressure roller 13 against the large roller 6.

The two sides of the push plate 9 are provided with push plate side panels 11, two ends of the push plate 9 are provided with push plate end panels 15, the push plate end panels 15 are provided with forced pressure rollers 13, the number of the forced pressure rollers 13 on each forced pressure pump suction device is 2-4, the forced pressure rollers 13 are all rollers with small sizes, the rollers with small sizes are adopted in the prior art to carry out one-to-one forced pressure, and a one-to-many mode cannot be adopted due to the fact that the rollers are small in size.

And the side sealing gasket 12 attached to the mesh belt 4 is arranged on the side plate 11 of the push plate, and the side sealing gasket 12 is molded on the side plate 11 of the push plate through a vulcanization process.

Be equipped with the sealed 17 of tip that laminates with guipure 4 on the push pedal end panel 15, the cross-section of the sealed 17 of tip is the L type, and the space between push pedal end panel 15 and the guipure 4 is inserted in the one side compression of the sealed 17 of tip, and the opposite side laminating of the sealed 17 of tip is at the outer wall of push pedal end panel 15.

The center of the push plate 9 is provided with a suction hole 10 connected with an external suction pump in a penetrating way. The sealing between the whole strong pressure pump suction device and the mesh belt 4 is realized through the side sealing gasket 12 and the end sealing gasket 17, so that water pressed down by strong pressure can be directly sucked away through an external suction pump, and the whole dehydration performance is very good.

And a bearing 16 is arranged on the push plate end surface plate 15, and the two ends of the strong pressure roller 13 are tightly matched with the bearing 16 in a pressing manner.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
