Abstract

The utility model relates to a rotary type feeding plate of a centrifuge. The lower ends of an inner plate and an outer plate of the feeding plate are connected and fixed through a pin, the top end face of the inner plate is fixedly connected with the lower end of a drive shaft, a material passing interlayer space is formed between the inner plate and the outer plate, and the upper end of the drive shaft is connected with a drive motor. The rotary type feeding plate of the centrifuge has the advantages that slurry is even in distribution and is fully distributed on the whole inner wall of a rotary drum, the vibration intensity when the centrifuge operates is greatly reduced, the time for filter residue to be fully filled in the rotary drum is greatly shortened, the working efficiency of the centrifuge is improved and the like, and the rotary type feeding plate of the centrifuge is suitable for serving as the rotary feeding plate of the centrifuge.

Description

The rotary cloth tray of centrifuge

Technical field

The utility model relates to a kind of rotary cloth tray of centrifuge.

Background technology

Centrifuge is a kind of high performance centrifugal filtration separation equipment, the centrifugal force that runs up and produce that utilizes rotary drum (centrifugal basket), the filtrate of injecting in rotary drum is separated by the filter bag of lining in rotary drum, and filter residue is stayed in rotary drum, and filtrate flow to collector through liquid outlet; Be applicable to the solid phase shatter value high, granularity is moderate, and the suspension that liquid phase viscosity is little carries out the solid, liquid detached job, not only is suitable for the feed separation of the many kinds of small lot, also applicable production in enormous quantities the in enormous quantities; Be widely used in medicine, chemical industry, light industry, food, national defence and other industrial circle.

As shown in accompanying drawing one, slip to be separated flows in rotary drum 2 from feed pipe 6, in the centrifugal force field that the rotary drum High Rotation Speed produces, the liquid that slip is covered with in whole drum inner wall while slip automatically throws away rotary drum from the filter opening that the drum wall gathers, and filter residue is stayed in rotary drum.Slip is delivered in rotary drum 2 continuously, until till filter residue is full of whole rotary drum dischargeable capacity.

It is the plant equipment that runs up due to centrifuge, the dynamic balancing of rotating part must reach specification requirement, the guarantee centrifuge steadily, safely the operation, and the rotation parts that centrifuge instrument itself is joined are all through strict dynamic balancing check, and the vibrations index that has detected the operation of complete machine empty wagons before dispatching from the factory meets national standard, so the balanced degree key that centrifuge runs up is whether the slip in rotary drum distributes even, whether destroyed the dynamic balancing of empty machine after charging.

Adopt the centrifuge (seeing accompanying drawing two) of side putting type feed pipe, during charging, slip flows to position fixing in rotary drum linearly from the single mouth of pipe, impulsive force during outflow may be broken up the good filter cake layer of former cloth, if slip poor mobile performance, or solid particle wherein is difficult to be covered with very equably drum inner wall under the effect of simple centrifugal force than great; If cloth is uneven, rotary drum is inevitable produces strenuous vibration in the high speed rotary process, destroy the equipment traveling comfort, even leads to equipment breakdown.

Summary of the invention

The purpose of this utility model is to provide a kind of high efficiency, the safe and reliable rotary cloth tray that is used for centrifuge.

The utility model is achieved in the following ways:

The rotary cloth tray of centrifuge, the inner disc of cloth tray and the lower end of outer disk are connected and fixed through pin, and the inner disc top end face is affixed with the driving shaft lower end, punishment in advance mezzanine space between inner disc and outer disk, the driving shaft upper end connects drive motors; It is charging aperture and following for discharging opening above the punishment in advance mezzanine space of entry table.

When the rotary cloth tray of this centrifuge is used, slip evenly is covered with whole drum inner wall, and the time that filter residue is full of rotary drum is shortened in the vibrations earthquake intensity when greatly reducing the centrifuge running simultaneously, improves the operating efficiency of centrifuge.

Description of drawings

The rotary cloth tray of Fig. 1 centrifuge is arranged on the structural representation on machine;

The centrifuge structure schematic diagram of the side putting type feed pipe that Fig. 2 commonly uses.

The specific embodiment

As shown in Figure 1: rotary cloth tray is formed by outer disk 5, inner disc 4, pin 3, driving shaft 10 assembly weldings, and endoporus and drive motors 9 with keyway by driving shaft 10 upper ends link; Drive motors is fixed on pedestal 11 with screw 8, driving shaft 10 relies on deep groove ball bearing 7 to be positioned in the dead eye of pedestal 11, and can turn round flexibly under the driving of motor, the mouth of pipe of feed pipe 6 is made Flat-mouth type, and insert between outer disk 5 and inner disc 4, a whole set of distribution device is fixed on centrifuge cover 1 with screw 12.

During the centrifuge charging, rotary drum 2 High Rotation Speeds, slip flows between outer disk 5 and inner disc 4 from feed pipe 6, and circumferentially throwing away from the discharging opening 15 between internal and external disk under the driving of drive motors 9, the plane that slip throws away be one from the rotary drum inner chamber upper left corner the oval tapered plane to the rotary drum inner chamber lower right corner, so just can guarantee that slip is covered with whole drum inner wall equably.

The rotating speed of drive motors 9 is faster, the cloth tray speed that throws away slip is also just faster, just can allow slip more, flow in centrifuges and can not increase the vibrations earthquake intensity of centrifuge from feed pipe 6 quickly, charging rate is fast, the centrifuge high efficiency has improved the output of centrifuge.
