Piston pushing centrifuge push rod capable of conveying materials

Technical Field

The utility model relates to a push away material centrifuge, the piston that can transport the material pushes away material centrifuge push rod specifically says so.

Background

A conventional piston pusher centrifuge is a continuously operating, pulse discharge, filter centrifuge. In the case of high speed operation, the material is continuously fed through a feed pipe at the open end of the drum and flows along a feed distributor onto the screen of the drum. The filtrate passes through the filter screen and is continuously discharged through the filtrate outlet, and filter residue accumulated on the inner surface of the filter screen is pushed out along the inner wall surface of the rotary drum by a pusher reciprocating relative to the rotary drum.

Because the material is fed in from the inlet pipe that is located the open end of rotary drum, the support of the main shaft of above-mentioned piston pusher centrifuge can only be made into unilateral support, and the bearing structure is that two bearings of main shaft are located the same side of rotary drum. The supporting structure of the rotary drum belongs to a cantilever structure, one end of the rotary drum is fixed on the main shaft or the push rod, and the other end of the rotary drum is a free end (capable of generating force parallel to the axial direction and force perpendicular to the axial direction). The axial feeding end of the rotary drum wall is connected with the main shaft or the push rod through the rotary drum bottom (a supporting structure) to support the rotary drum, and the axial discharging end of the rotary drum wall is not provided with a supporting structure and is connected with the main shaft or the push rod to support the rotary drum.

The cantilever structure of unilateral support leads to the free end of rotary drum to lead to shaking under the combined action of the power that is on a parallel with axial and perpendicular to axial, and the rotary drum bottom at rotary drum stiff end splits when serious, causes serious accident.

On the other hand, the mechanical characteristics of the unilateral support and the cantilever structure limit the increase of the diameter, the rotating speed, the length of a filtering area and the stage number of the rotary drum, so that the piston pusher centrifuge has a series of defects of easy vibration, small separation factor, short material filtering time, high material water content, large energy consumption for drying unit products, large washing water equivalent, large difficulty in treatment of used washing water, environmental protection cost increase, few stage numbers of the rotary drum, small production capacity, no large scale and the like.

SUMMERY OF THE UTILITY MODEL

To the above problem, an object of the utility model is to provide a piston that can transport the material pushes away material centrifuge push rod, send into the mode of rotary drum through changing the material, the support of having avoided piston to push away material centrifuge's main shaft can only be made unilateral support, the piston that causes pushes away material centrifuge's easy vibrations, the separation factor is little on the right side, material filter time is short excessively, material moisture content is too high, the dry energy consumption of unit product is big, wash water equivalent is too big, the washing water treatment degree of difficulty after using is big, the rotary drum progression is little on the right side, the productivity capacity is little on the right side, can not a series of shortcomings such as ups.

The utility model adopts the technical proposal that: the piston pushing centrifuge push rod capable of conveying materials is characterized by comprising a hollow push rod, a material channel and a washing water channel, wherein the material channel and the washing water channel are located on the push rod, the left end of the push rod is provided with a feed inlet, the right end of the push rod is provided with a washing water port, and a partition plate for separating the material channel and the washing water channel is arranged in the push rod.

Further, the material channel is a through hole or a circular seam arranged on the push rod; when the circular seam is adopted, two ends of the circular seam are connected through a connecting structure.

Furthermore, the washing water channel is a through hole or a circular seam arranged on the push rod; when the circular seam is adopted, two ends of the circular seam are connected through a connecting structure.

Further, the connecting structure is a combination of one or more of a plate, a column, a pipe and a fastener, or a combination of one or more of them and a fastener.

The utility model has the advantages and the characteristics that: the inside passageway that can supply material and wash water to carry that sets up of push rod, through the mode that changes the material and send into the rotary drum, make the support of the main shaft of piston pusher centrifuge who cooperates with it can make bilateral bearing structure, make the diameter big, the rotational speed is fast, filtering area length is long, the rotary drum that the progression is many becomes possible, make the piston pusher centrifuge who is equipped with this push rod possess and be difficult to shake, the separation factor is big, filtering area length increases the extension of material filter time, the filter residue moisture content is low, wash water equivalent is little, the productivity is big, large-scalization, and the while has the safety and stability, ton product power consumption low advantage.
