Detailed Description
The present utility model is described in further detail below with reference to the drawings to enable those skilled in the art to practice the utility model by referring to the description.
As shown in fig. 1 and 2, an embodiment of the present utility model provides a sludge treatment apparatus including: an outer cylinder 1 which is disposed obliquely; the screen body 2 is rotatably arranged inside the outer cylinder body 1, an annular space is formed between the screen body 2 and the outer cylinder body 1, the screen body 2 is obliquely arranged in a mode that a first end 8 is high and a second end is low by 9, the screen body 2 comprises a plurality of sectional screen bodies which are sequentially connected from the first end 8 to the second end 9, the sectional screen bodies are all in a cylindrical structure, and the diameters of the sectional screen bodies are sequentially reduced along the direction from the first end 8 to the second end 9; a first rotary motor connected to a second end of the screen 2 to drive the screen 2 to rotate; the pushing mechanism is arranged in the screen body 2; the feeding mechanism is connected to the higher end of the outer cylinder body 1 and is communicated with the screen body 2; the discharging mechanism is connected to the lower end of the outer cylinder body 1 and is communicated with the screen body 2; and a drain port 10 provided at a lower portion of the outer cylinder 1.
When the silt treatment device provided by the utility model is used for treating silt, the silt firstly enters the inside of the screen body 2 through the feeding mechanism, flows from the first end 8 to the second end 9 under the conveying action of the pushing mechanism, and along with the rotation of the screen body 2, the moisture in the silt is separated between the screen body 2 and the outer cylinder body 1 under the extrusion and centrifugal actions of the screen body 2, and finally the silt is discharged by the discharging mechanism, and the moisture is discharged by the water outlet 10. Because the diameter of the sectional screen body is gradually reduced, the flow is instantaneously reduced in the process that the sludge enters the next sectional screen body from the last sectional screen body, the born external pressure is increased, and the water in the sludge is accelerated to be discharged. Moreover, since the plurality of segment screens are all cylindrical, the bottom wall of the last segment screen will be connected to the side wall of the next segment screen, i.e. the bottom wall of the last segment screen forms a step surface (e.g. step surface 16 between segment screen 3 and segment screen 12). When the sludge flows to the position of the step surface, the sludge can bear larger external pressure, and the water in the sludge is further promoted to be discharged. Therefore, the utility model improves the water discharging efficiency in the sludge by designing the sectional screen body, thereby improving the treatment efficiency for dewatering the sludge.
In addition, the utility model also provides a mode of arranging the outer cylinder body and the screen body in an inclined mode. Based on this setting, silt flows not only relies on pushing equipment's power to the second end from the first end of screen frame, still relies on its own gravity, based on this, can impel silt to flow to the second end from the first end of screen frame, and then helps improving the treatment effeciency to silt dehydration.
The outer cylinder 1 may be mounted on a bracket.
The feeding mechanism is a feeding port 6 for feeding the sludge into the screen 2. The discharging mechanism can be a discharging hole 7 which is communicated with the sludge collecting device. The water outlet 10 is provided at the lower portion of the outer tub 1, and may be provided at a position near the lower end of the side wall of the outer tub 1 so that water is discharged under the action of gravity.
In a preferred embodiment, the sludge treatment apparatus comprises three segmented screens 3,12,13, the three segmented screens 3,12,13 increasing in length in sequence in the direction from the first end 8 to the second end 9.
As the diameters of the three segmented screens 3,12,13 decrease in sequence in the direction from the first end 8 to the second end 9, the length of the lower segmented screen is increased to reduce the volume difference between the next and the last segmented screen. Preferably, the volume of the next segmented screen is smaller than the volume of the previous segmented screen.
In a preferred embodiment, in the sludge treatment apparatus, the diameter of the next one of the three section screens 3,12,13 is 3/4 of the diameter of the previous section screen in the direction from the first end 8 to the second end 9.
Based on the arrangement, the flow is instantaneously reduced in the process that the sludge enters the next section screen from the last section screen, the born external pressure is increased, and the water in the sludge is accelerated to be discharged. Moreover, when the sludge flows to the position of the step surface formed by the bottom wall of the last sectional screen body, the sludge is subjected to larger external pressure, and the water in the sludge is further promoted to be discharged. Therefore, the utility model improves the water discharging efficiency in the sludge by designing the sectional screen body, thereby improving the treatment efficiency for dewatering the sludge.
In a preferred embodiment, in the sludge treatment apparatus, the pushing mechanism includes a screw pushing rod 4 and a second rotating motor, the screw pushing rod 4 is rotatably disposed inside the screen body 2, and the first rotating motor is connected to one end of the screw pushing rod 4 to drive the screw pushing rod 4 to rotate.

Specifically, both ends of the screw pushing rod 4 protrude from both ends of the outer cylinder 1, and the second rotary electric machine is connected to one end of the screw pushing rod 4. The screw ejector pin 4 has a spiral-shaped ejector pad.
One end of the spiral pushing rod is provided with a rolling bearing, the second end of the screen body is connected with a screen body supporting rod, the screen body supporting rod is connected to the rolling bearing, and the first rotating motor is connected to the rolling bearing through a gear set or a rotating transmission member, so that the screen body is driven to rotate.
