Description

Technical Field

[0001] The present invention relates to the technical field of horizontal screw sedimentation centrifuges, and particularly to a horizontal screw sedimentation centrifuge with an automatic feeding and discharging module. Background Art

[0002] A horizontal sedimentation screw centrifuge consists of components such as a high-speed rotating drum, a screw with the same rotation direction as the drum and a slightly higher or lower rotational speed than the drum, and a differential. The material is pushed by the blades on the screw pusher to the slag discharge port at the small end of the drum for discharge, while the liquid phase overflows through the overflow holes at the large end of the drum. This cycle continues to achieve the purpose of continuous separation.

[0003] When using a horizontal sedimentation screw centrifuge to separate sewage, the flocculant needs to be mixed with the sewage and then the mixed liquid is introduced into the centrifuge. The centrifugal force is used to separate the solid and liquid phases in the sewage. When separating high-viscosity sewage, due to the high viscosity of the sewage, the sewage may become blocked during separation inside the drum. When blockage occurs, the screw pusher will generate abnormal vibrations. During the sewage separation process, there is a lack of timely monitoring and response to vibrations. When abnormal vibrations are detected, manual operation is required to close the feed valve. At the same time when the feed valve is closed, some sewage will still be introduced into the centrifuge, increasing the blockage pressure of the centrifuge. Also, when blockage occurs, accumulation is likely to occur at the feed inlet and the solid discharge outlet of the centrifuge. At this time, it is difficult for the centrifuge to perform normal feeding and discharging, and some of the solids inside the drum of the centrifuge are not fully squeezed and dehydrated. When the solids are discharged, their water content is high and it is difficult to remove the water, so the overall use effect needs to be further improved. Summary of the Invention

[0021] In the present invention, a feeding treatment mechanism is provided. When a blockage occurs inside the drum, the feeding valve closes, and the sewage stops entering. Through the cooperation of the lifting seat, the diversion housing, the first plug, the inner connecting pipe, the second plug, the diversion pipe, and the sealing pipe, the sewage that enters the feeding pipe during this period can be diverted to the diversion pipe and discharged through an external pipe, avoiding the sewage entering and aggravating the blockage degree at the feeding port and inside the drum. At the same time, through the cooperation of the cam, the synchronous plate, and the impact plate, while switching the sewage feeding direction, continuous vibration is generated at the feeding pipe through impact to vibrate and dredge the blocked sewage at the feeding port, preventing the accumulation of materials at the feeding port and affecting subsequent treatment work.

[0022] In the present invention, an extrusion and vibration mechanism is provided. When an abnormal vibration and material blockage occur inside the drum, the inner connecting cylinder, the first overflow screen, the four dehydration plates, and the second overflow screen can assist in extruding and dehydrating the incompletely dehydrated solid phase discharged during the blockage, avoiding excessive water content in the solid phase. At the same time, through the cooperation of the driving disk mounting cover frame, the vibrating plate, and the vibrating block, continuous impact vibration is carried out at the feeding pipe when a blockage occurs to accelerate the dredging and discharge of the solid phase, preventing the accumulation of materials at the feeding pipe when the drum is blocked and affecting the discharge of the solid phase.

[0023] In the present invention, a detection and deceleration mechanism is provided. When separating sewage, the abnormal vibration of the connecting shaft can be detected by the detection block cooperating with the contact sensor. If abnormal vibration is detected, the detection stops. At the same time, the deceleration plate and the connecting piece are used to assist in decelerating the high-speed rotating connecting shaft, avoiding the problem that the blockage degree is aggravated due to the continuous high-speed rotation of the connecting shaft and the screw pusher when blocked.

[0043] When the present invention is in use and during separation, the sewage mixed with the flocculant is introduced from the feed pipe 13. After the sewage enters the interior of the feed pipe 13, it is then introduced into the coupling shaft 17, and then through the coupling shaft 17 into the interior of the screw feeder 14, and is discharged through the discharge pipe 16 into the interior of the drum 11. The drum 11 and the screw feeder 14 rotate at different speeds. Under the action of centrifugal force, the solid-phase particles with a larger density are settled to the inner wall of the drum 11, and are continuously pushed out of the small-end side of the drum 11 by the screw feeder 14 rotating at different speeds for extrusion dehydration and then discharged through the blanking pipe 18 on the small-end side. The liquid phase with a relatively smaller density has a smaller centrifugal force, and the liquid phase forms a liquid ring layer and overflows outwards through the overflow holes 15 on one side of the drum 11;

[0044] During the normal separation process of the sewage, the screw feeder 14 and the coupling shaft 17 keep rotating normally. Once there is a situation of material accumulation and blockage inside the drum 11, the screw feeder 14 and the coupling shaft 17 generate abnormal vibrations. When the coupling shaft 17 vibrates, it contacts the detection block 241. The detection block 241 is extruded by the vibration of the coupling shaft 17 and slides inside the movable box 24. When the detection block 241 slides, it drives the contact shaft 242 to contact the contact sensor 243. At this time, the contact sensor 243 feeds back a contact signal to the system. When the system receives the contact signal, it indicates that there is an abnormal blockage inside the drum 11;

[0045] When there is an abnormal blockage inside the drum 11, control the drum 11 to reduce its rotational speed until it stops rotating. Synchronously, control the hydraulic telescopic rod to drive the movable box 24 to move away from the coupling piece 22. At this time, under the action of the meshing of the rack and the two gears, drive the deceleration plates 25 on both sides to move closer to the coupling piece 22 and contact the coupling piece 22 to reduce the rotational speeds of the coupling shaft 17 and the screw feeder 14. Subsequently, control the rotational speed of the screw feeder 14 to be reduced through the control system;

[0046] Synchronously, close the feed valve, control the hydraulic telescopic rod to drive the lifting seat 41 to descend and drive the redirecting housing 42 to descend until the position of the diversion inlet 421 is opposite to that of the inner connecting pipe 131, and the position of the diversion outlet 422 is opposite to that of the closed pipe 51. While the feed valve is closed, the sewage entering the interior of the feed pipe 13 is discharged through the inner connecting pipe 131, the diversion inlet 421, the redirecting housing 42, and the diversion outlet 422. At this time, the plugging block 433 moves downward under the pressure of the sewage. The sewage flows out through the diversion outlet 422 and is introduced into the diversion pipe 5 through the closed pipe 51 and then exported through the diversion pipe 5 to the external pipeline;

[0047] Synchronous. When controlling the servo motor to drive two gears to rotate meshing with each other, the cam 411 rotates and contacts and presses the synchronous plate 61 at the lower position to make it slide. When the synchronous plate 61 slides, it drives the impact plate 62 to impact the mounting box 6 and the extension pipe 4, driving the mounting cover 3 and the extension pipe 4 to generate continuous vibration to accelerate the dredging of the materials at the feeding place;

[0048] After the sewage flowing into the inside of the feed pipe 13 is discharged instantaneously when the feed valve is closed, the lifting seat 41 moves back to its original position. At this time, the drive shaft 43 keeps rotating continuously and drives the stirring frame 44 to rotate at the feed port to dredge the sewage. At the same time, the cam 411 keeps pressing the synchronous plate 61 at the upper position to drive the impact plate 62 to impact the mounting box 6 and the extension pipe 4, so that the mounting cover 3 and the extension pipe 4 generate continuous vibration;

[0049] After the rotating drum 11 stops rotating completely, clear water is injected inward from the feed pipe 13 through the clear water inlet pipe to dilute the blocked sewage;

[0050] The spiral pusher 14 keeps rotating at a low speed, the drive disk 7 rotates regularly under the drive of the servo motor, controls the double-acting hydraulic telescopic rod to drive the extension block 731 to extend to both sides. After the extension block 731 extends in place, it can contact and press the vibration plate 81 to drive it to move. The vibration plate 81 makes irregular shaking under the action of the moving block 82 and the extrusion of the extension block 731. When the vibration plate 81 shakes, it can drive the vibration block 83 to impact at the discharge pipe 18 to generate continuous vibration at the discharge pipe 18 to accelerate the discharge of the solid phase;

[0051] The solid phase blocked and discharged inside the rotating drum 11 is discharged downward in the discharge pipe 18 and falls between the first dewatering plate 72 and the second dewatering plate 72. At this time, the liquid in the solid phase that has not been completely dewatered first leaks through the first overflow net 711 and is discharged through the inside of the inner connecting cylinder 71 and other first overflow nets 711. Subsequently, control the hydraulic telescopic rod to drive the drive plate 74 to move closer to the middle position. The first dewatering plate 72 and the second dewatering plate 72 move closer to each other and squeeze the solid phase. At this time, the squeezed-out liquid is discharged through the first dewatering plate 72 and the second overflow nets 721 on both sides of the second dewatering plate 72. At the same time, control the drive disk 7 to rotate 90° to switch to the middle area between the second dewatering plate 72 and the third dewatering plate 72 to align with the solid phase discharge position. The solid phase discharged from the discharge pipe 18 slowly and continuously falls into the corresponding extrusion area between the four dewatering plates 72 to assist in the dehydration work of the solid phase that has not been completely dehydrated;

[0052] After the blocked materials inside the rotating drum 11 are completely discharged, clear water is continuously introduced into the spiral pusher 14 and the inside of the rotating drum 11 through the clear water inlet pipe at the feed pipe 13 to clean the machine body. After the machine body is cleaned, subsequent normal separation work can be carried out.
