Abstract

The utility model relates to a centrifugal solid-liquid separator which comprises a rotary drum arranged inside a machine shell, wherein, the rotary drum is formed by the combination of a screen-lined conical part and a screen-lined cylindrical part; the conical part of which the diameter changes from small to large is near to one end of a rotary shaft, and the cylindrical part is arranged at the other end; the end face of the cylindrical part of the rotary drum is also provided with a baffle plate with adjustable clearance. The rotary drum is driven by the rotary shaft to separate hydrous dregs pumped into the rotary drum in the conical part of the rotary drum under the action of centrifugal force, when the dregs slide to the cylindrical part of the rotary drum and damped by the adjusting baffle plate, the dregs are separated again under the action of centrifugal force. The utility model has the advantage of favorable dewatering effect, and the clearance can be adjusted to control the water content of the dregs.

Description

A kind of centrifugal solid-liquid separating machine

The utility model relates to a kind of centrifugal solid-liquid separating machine that outside flow filtration is arranged that is used for.

At existing industry and the poor slag sewage of food service industry discharging, the ight soil of livestock and poultry etc., for the ease of transportation, storage and utilization again, all should carry out processed, this is the effective way of protection environment and resource reutilization.And present dehydration generally has following several method: the one, and extrusion dehydration is as pressafiner, plate and frame type filter-press etc.; The 2nd, filtering means dehydration filters as aqueduct, and gravity freely filters etc.; The 3rd, centrifugal dehydration is as tripod type centrifuge, helical-conveyer centrifugal, conical barrate centrifugal machine etc.In numerous dewaterings, the highest with the plate and frame type filter-press dehydration rate, but it can only intermittent work, because will feed and discharging.In the dewaterer of continuous operation, higher with the conical barrate centrifugal engine efficiency, moisture poor slag is pumped to rotary drum (cone-element), under action of centrifugal force, to big end, water is dished out from screen cloth from the small end slippage of rotary drum (cone-element), and poor slag is then dished out from the rotary drum large end face, but the dehydration rate of conical barrate centrifugal machine is not high, and the dehydration rate of the poor slag of difference is difficult to control.

The purpose of this utility model is: provide a kind of special-shaped rotary drum also can control a kind of centrifugal solid-liquid separating machine of poor slag dehydration rate.

In order to achieve the above object, the technical solution adopted in the utility model is: it comprises by rotating shaft and drives the rotary drum be contained in the casing, inserts the feed pipe in the rotary drum.Described rotary drum by change from small to big near rotating shaft one end diameter, the conical portion of liner screen cloth and the cylindrical part that the other end is the liner screen cloth combine; The bottom surface of the cylindrical part of rotary drum, be equipped with by controllable register mechanism controls gap, and the controllable register that can rotate with rotary drum; Toroidal membrane is equipped with at the end face extended line place of rotary drum cylindrical part, and housing is separated, and forms cinder notch and delivery port.

The useful effect that the utlity model has is:

1, employing makes the long and generation extruding in the time that rotary drum stops of poor slag by the rotary drum that conical portion and cylindrical portion are grouped into, and dehydrating effect is good;

2, controllable register is equipped with in the rotary drum side of cylindrical part, and the available adjustment baffle mechanism is adjusted the gap length between them, can control the moisture content of poor slag.

Below in conjunction with accompanying drawing, the utility model will be further described.

Description of drawings:

Fig. 1 is first kind of structural representation of the present utility model;

Fig. 2 is second kind of structural representation of the present utility model;

Fig. 3 is the third structural representation of the present utility model;

Fig. 4 is the 4th a kind of structural representation of the present utility model.

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, be contained in the casing 2 rotary drum by change from small to big near rotating shaft 1 one end diameters, the conical portion 3 of liner screen cloth 4 and the other end be that cylindrical part 5 by liner screen cloth 6 combines.The bottom surface of the cylindrical part 5 of rotary drum, be equipped with by controllable register mechanism 7 control gaps, and the controllable register 8 that can rotate with rotary drum.Outside the end face extended line of rotary drum cylindrical part 5, toroidal membrane 10 is housed, housing 2 is separated, form cinder notch 11 and delivery port 12.

Above-described controllable register 8 is that disc controllable register (as shown in Figure 1 and Figure 2) or side bus are the conical controllable register (as shown in Figure 3) of straight line or the conical controllable register (as shown in Figure 4) that side bus is camber line.

Above-described controllable register mechanism 7 is with regulating bolt (as Fig. 1, Fig. 3, shown in Figure 4), or in be with the bolt (as shown in Figure 2) of spring.

Feed pipe 9 is through housing 2, controllable register 8 put in always to rotary drum near the bottom, rotary drum is rotation at a high speed under the drive of rotating shaft 1, after moisture poor slag pumps into rotary drum from feed pipe 9, under action of centrifugal force, shed and be lined with on the rotatory drum wall of screen cloth, and with screen cloth 4 between produce higher relative sliding velocity, shed the casing 2 from delivery port 12 outflows from the water that screen cloth 4 is separated, poor slag is piled up at the rotary drum cylindrical wall to big end from the small end slippage of rotary drum, be pressed against the rotary drum port gradually, and be subjected to controllable register 8 dampings, being extruded the water of separating with centrifugal force again dishes out from the cylindrical screen 6 of rotary drum, poor slag after the dehydration is emitted by slag notch 11 after then being extruded the slit between rotary drum cylindrical shape part end face and controllable register and dishing out.

Adjust the gap of controllable register and rotary drum end face, can control the water content of poor slag.Change into stage clip and bolt with the bolt controllable register, can realize the automatic adjusting of poor slag moisture content.
