Abstract

The utility model relates to a filtering-assisting rotating drum of a centrifuge. The filtering-assisting rotating drum of the centrifuge is arranged in a centrifuge shell. The filtering-assisting rotating drum of the centrifuge comprises a rotating drum bottom, a rotating drum cylinder and filtering cloth, wherein the rotating drum cylinder is arranged on the rotating drum bottom, the filtering cloth is arranged on the inner wall of the rotating drum cylinder, a plurality of filtering-assisting holes are formed in the rotating drum bottom, a filtering sheet is arranged on each filtering-assisting hole, and each filtering-assisting hole is communicated with the centrifuge shell. By the adoption of the filtering-assisting rotating drum of the centrifuge, filtering-assisting separation can be conducted on materials which are difficult to separate through the centrifuge, the moisture content of filtering residues meets the standard, the drying effect of the filtering residues is good, the separation time is shortened, the separation can be quickly completed, and therefore work efficiency is improved.

Description

A kind of centrifuge drainage rotary drum

Technical field

the utility model relates to a kind of centrifuge, is specifically related to a kind of centrifuge drainage rotary drum.

Background technology

centrifuge is that the centrifugal inertial force that utilizes drum rotating to produce is realized the separation of suspension, emulsion and other heterogeneous material or concentrated machine.

according to separate mode, centrifuge can be divided into filtering type, decanter type and separate type three basic forms of it; According to solid phase discharge way, centrifuge can be divided into gravity dumping, artificial top discharging, manually descend the types such as discharging, centrifugal discharge, scraper discharging, vacuum intake and screw unloading.

perforated wall centrifuge rotary drum is mainly made up of high-revolving rotary drum, the filter cloth that covers in rotatory drum wall; operation principle is: when the suspension that will separate enters after bowl; the rotary drum of High Rotation Speed produces powerful centrifugal force and solid phase particles is deposited on the filter cloth of drum inner wall; liquid phase is thrown in casing and is discharged by the aperture on filter cloth and rotatory drum wall simultaneously; when the de-liquid of the high speed of solid phase by certain hour reaches after the index request of water capacity, shut down the discharge process of finishing the work.

in actual production, due to the characteristic difference of various materials, so the characteristic of the filter residue producing through separation is also different, the relative tack of most materials is little, solid particle size is large, can filtrate successfully be drawn off by filter cloth, and have the saturating filter of partial material bad, when partial material enters after rotary drum, the mesh of filter cloth may be stopped up, make the material adding be difficult to separate below, cause the liquid in material in rotary drum to get more and more, sometimes within several hours, just can complete possibly separation, and in causing disengaging time to increase, because liquid phase concentrates on carrier ring shape inside rotary drum, form relative motion with solid phase, cause the vibration of centrifuge to strengthen, affect the result of use of centrifuge, sometimes even cannot thoroughly filter.

Summary of the invention

technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, a kind of centrifuge drainage rotary drum is provided, by offer multiple drainages hole at the bottom of rotary drum, drainage is provided with filter disc on hole, drainage hole communicates with casing, and in the time of needs filter liquide, liquid is isolated by casing and discharged from drainage hole, reduce disengaging time, increase work efficiency.

for solving above technical problem, the utility model is taked following technical scheme:

a kind of centrifuge drainage rotary drum, be arranged in centrifuge casing, the rotary drum at the bottom of comprising rotary drum, on being arranged at the bottom of rotary drum and be arranged on the filter cloth on rotary drum inwall, offers multiple drainages hole at the bottom of rotary drum, drainage is provided with filter disc on hole, and drainage hole communicates with casing.

preferably, at the bottom of rotary drum, be circular.

preferably, drainage hole is along the circumferential direction uniformly distributed at the bottom of rotary drum.

preferably, drainage hole is kidney-shaped.

preferably, on filter disc is fixed at the bottom of rotary drum by pressure ring.

the utility model compared with prior art tool has the following advantages:

the utility model can carry out drainage separation to the material by the more difficult separation of centrifuge, when material stops up filter cloth when not easily separated, liquid can flow out in the drainage hole from the bottom of rotary drum, and the liquid flowing out by drainage hole enters casing and discharges, the utility model by most liquid after process in drainage hole, all the other liquid are deviate from through rotary drum filter cloth, can make the water capacity of filter residue up to standard, filter residue and drying is effective, can also comparatively fast complete separation process, reduce disengaging time, improved operating efficiency.

Detailed description of the invention

below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.

as shown in Figure 1, centrifuge drainage rotary drum of the present utility model, be arranged in centrifuge casing 1, comprise at the bottom of circular rotary drum 2, be arranged at the bottom of rotary drum the rotary drum 3 on 2 and be arranged on the filter cloth 4 on rotary drum 3 inwalls, at the bottom of rotary drum, offer the drainage hole 5 of multiple kidney-shapeds on 2, drainage hole 5 is along the circumferential direction being uniformly distributed on 2 at the bottom of rotary drum, on drainage hole 5, be provided with filter disc 6, filter disc 6 is fixed at the bottom of rotary drum on 2 by pressure ring 7, drainage hole 5 communicates with casing 1, in the time that needs pass through drainage hole 5 filter liquide, liquid is separated from drainage hole 5 and is discharged by casing 1.

the course of work of the present utility model is: when centrifuge work, the utility model rotary drum High Rotation Speed, joins not segregative suspension rotary drum from feed arrangement, and liquid flows out from the drainage hole 52 at the bottom of rotary drum, enter casing and discharge, by after most liquid handling, all the other liquid are deviate from through rotary drum filter cloth 4, and the water capacity of filter residue is up to standard, the de-liquid of filter residue is effective, reduce disengaging time simultaneously, comparatively fast complete separation process, improved operating efficiency.

in sum, the utility model can carry out drainage separation to not segregative material, makes the water capacity of filter residue up to standard, and filter residue and drying is effective, can also comparatively fast complete separation process, reduces disengaging time, has improved operating efficiency.

above the utility model is described in detail, but the utility model is not limited to the above embodiments.All equivalences of doing according to Spirit Essence of the present utility model change or modify, and all should be encompassed in protection domain of the present utility model.
