specific Embodiment

[0026] like figure 1 As shown, a three-stage piston pusher centrifuge drum device according to the present invention includes a first-stage drum 1, a second-stage drum 2 and a third-stage drum, and the third-stage drum adopts Cylindrical cone structure, that is, includes a circular segment 3 and a conical segment 4 . The conical structure makes the centrifugal force of the drum stronger, and the moisture content of the material at the discharge port is lower after being dried; the front section of the third-stage drum is round and unchanged, and the rear section is changed to a cone shape. This structure not only makes the material under the centrifugal force Under the action, it automatically goes to the back section, reducing the resistance, and the material becomes thinner as it goes to the back section, thereby reducing the moisture content of the material. The circular segment 3 is fixedly connected with the third-stage drum bottom 12, and the third-stage drum bottom 12 ...

Abstract

The invention discloses a three-stage piston pushing centrifuge drum device, and relates to the technical field of mechanical pushing centrifuges. The three-stage piston pushing centrifuge drum devicecomprises a first-stage drum, a second-stage drum and a third-stage drum; the third-stage drum is of a column taper structure, screen cloths in the three-stage piston pushing centrifuge drum device are all made of full-ceramic abrasion-resisting screen cloths; the effective filtering length of the first-stage screen cloth is 300-360 mm, the effective filtering length of the second-stage screen cloth is 360-420 mm, and the effective filtering length of the third-stage screen cloth is 300-360 mm; and a material distributing part in the three-stage piston pushing centrifuge drum device is of a truncated-cone-type structure, and the cross section of a material distributing hopper is in a isosceles trapezoid shape. The three-stage piston pushing centrifuge drum device is simple in structure, capable of conducting equipment maintaining conveniently and lowering the cost, large in drum centrifugal force, good in material dehydration water, large in screen cloth filtering area, capable of prolonging the service life of the screen cloths, and applicable to separation of fine powder materials and low-concentration suspension materials.

Description

technical field [0001] The invention belongs to the technical field of mechanical pusher centrifuges, and in particular relates to a three-stage piston pusher centrifuge drum device. Background technique [0002] The piston pusher centrifuge is a filter centrifuge that uses the pusher disc to continuously push out the filter cake formed in the drum to discharge. Because it is filtered by a thick layer of filter cake, the leakage of fine particles is small, and the change of the concentration of the suspension is small. Not very sensitive, suitable for separation of various materials. In order to achieve low filter cake water content, it is desirable to lengthen the drum to increase the residence time of the separated material in the drum. However, as the length of the drum increases, the resistance to pushing the filter cake also increases, and often due to the insufficient strength of the filter cake, the filter cake is arched or piled up, thereby destroying the dehydratio...
