Description

Technical Field

[0001] The present invention relates to the technical field of sludge dewatering equipment, and particularly to a spiral sludge dewatering machine. Background Art

[0002] Sludge dewatering is a sludge treatment method that removes water from fluid raw, concentrated or digested sludge and converts it into semi-solid or solid sludge blocks. The spiral sludge dewatering machine can be widely used in municipal sewage treatment projects and water treatment systems in industrial sectors such as petrochemical, light industry, chemical fiber, papermaking, pharmaceutical, and leather industries.

[0003] During the use of the existing spiral sludge dewatering machine, although the sludge and flocculant can be stirred by a stirring device, due to the relatively single stirring method, the stirring speed cannot be automatically adjusted according to the amount of sludge, thus reducing the mixing effect. In order to improve the stirring efficiency, some spiral sludge dewatering machine equipment uses a servo motor to drive the stirring device to stir the sludge and flocculant. Although the stirring speed can be changed, the energy consumption will increase and the cost is also relatively high.

[0004] Therefore, in order to solve the above-mentioned technical problems, a spiral sludge dewatering machine is needed. Summary of the Invention

[0056] Among them, the pumping - out pump 51 is arranged on the workbench 1 through a mounting bracket.

A discharging bin 542 communicated with its interior is arranged on the lower surface at the upper end of the sleeve 54. The first pipe 52 and the second pipe 53 are respectively arranged at the feeding end and the discharging end of the pumping - out pump 51. One end of the first pipe 52 is arranged in the discharging hole, and one end of the second pipe 53 extends into the interior of the lower end of the sleeve 54. The second driving motor 55 is arranged on the upper end of the sleeve 54 through a mounting bracket, and the driving end of the second driving motor 55 extends into the sleeve 54.

The water - collecting tank 57 is arranged on the workbench 1 through a support rod and is attached to the lower surface of the sleeve 54, and a plurality of filtering holes 541 are respectively located in the water - collecting tank 57.

[0057] Preferably, a valve (not marked in the figure) is arranged on the discharging pipe 571 to facilitate controlling the discharge of the water in the water - collecting tank 57.

[0058] Specifically, when the present invention needs to be used, first, an external discharging device and a blending device are respectively connected to the feeding pipe and the blending pipe, and then sludge and flocculant are discharged into the mixing barrel 2. Secondly, the first driving motor 33 is started, and the first stirring member 35 and a plurality of second stirring members 321 are driven to rotate by the first driving motor 33, so as to stir and mix the sludge and the flocculant. Thirdly, the pumping pump 51 and the second driving motor 55 are started. The sludge in the mixing barrel 2 is pumped into the sleeve 54 by the pumping pump 51, and the screw rod 56 is driven to rotate by the second driving motor 55, thereby driving the sludge to move. During the moving process, the sludge is subjected to spiral extrusion, so as to separate the sludge and water. The separated water flows out through the filter holes 541, finally falls into the water collecting tank 57, and is discharged from the discharging pipe 571. The sludge is finally discharged through the discharging bin 542, thereby realizing the dehydration work of the sludge.

[0059] It should be noted that the first driving motor 33 works and drives the guide rod 34, the first stirring member 35 and a plurality of driving gears 311 to rotate in sequence, so as to drive a plurality of driven gears 314 meshing therewith to rotate, thereby driving a plurality of transmission rods 313 to rotate, and then driving a plurality of linkage blocks 324 engaged therewith to rotate in sequence, thereby driving a plurality of linkage rods 323 and a plurality of second stirring members 321 to rotate, so as to stir the sludge and the flocculant.

[0060] It should be noted that during the process of adding sludge and flocculant, due to gravity, the pressure plate 411 is driven to descend, thereby driving the telescopic end of the first telescopic rod 412 to contract, and causing the second spring 413 to be compressed. At the same time, the pressure plate 411 drives the first rod 414 and multiple second rods 4141 to descend in sequence. During the descent of the second rod 4141, the second rod 4141 descends along the limiting plate 423, and the limiting plate 423 and the clamping plate 424 move away from the second rod 4141 respectively, thereby driving the telescopic end of the second telescopic rod 422 to contract. At the same time, the third spring 425 is compressed. When the limiting plate 423 stops moving, at this time, the clamping plate 424 completely disengages from the third plate 4161, and the upper second rod 4141 contacts the third plate 4161. The second rod 4141 continues to descend, and drives the third plate 4161 and the second plate 416 to rotate in sequence, thereby driving the third rod 433 and the connecting wheel 434 to rotate in sequence, driving one end of the main rope 437 to wind around the connecting wheel 434, and driving multiple auxiliary ropes 438 to rise through the other end of the main rope 437, thereby driving multiple linkage blocks 324 and multiple linkage rods 323 to rise in sequence. When multiple linkage blocks 324 rise and are limited in multiple limiting holes 3131 at the top, at this time, due to the resilience of the third spring 425 itself, the limiting plate 423 and the clamping plate 424 are driven to move, so that the limiting plate 423 moves between the two second rods 4141, and the third plate 4161 is inserted into the clamping plate 424. And at this time, the second rod 4141 does not contact the third plate 4161.

[0061] It should be noted that the greater the gravity received by the pressure plate 411, the higher the rising height of the linkage block 324, so that it is limited in a higher limiting hole 3131, and the rotation speed of multiple second stirring members 321 is accelerated.

[0062] In summary, for a spiral screw sludge dewatering machine according to an embodiment of the present invention, on the one hand, through the cooperation between the pressure device 41, the transmission device 43 and the stirring device 3, it is convenient to change the rising height of the linkage block 324 through the gravity received by the pressure plate 411, so as to automatically adjust the rotation speed of multiple second stirring members 321. On the other hand, through the cooperation between the limiting device 42 and the pressure device 41, it is convenient to limit the third plate 4161 by the clamping plate 424, thereby avoiding the linkage block 324 being located between the two driven gears 314, and avoiding the situation that the second stirring member 321 stops rotating.
