Description

Technical Field

[0001] This utility model relates to the field of sludge co-firing, and in particular to a dewatering device for sludge co-firing. Background Technology

[0002] With the increase in urban sewage treatment rate, the problem of harmless sludge disposal has become increasingly serious. Sludge co-firing is a common sludge treatment method. The principle is to send sludge into a boiler and co-fire it with coal. By using sludge co-firing to treat sludge, the volume reduction, stabilization and harmlessness of sludge can be achieved to a certain extent.

[0003] The announcement number CN212610213U discloses "A dewatering device for sludge co-firing in thermal power plants", which includes a box body. The top of the left side of the box body is connected to a feed pipe. A guide plate is fixedly connected to the inner cavity of the box body. The top of the guide plate has a filter hole. A waterproof box is fixedly connected to the bottom of the inner cavity of the box body. An electric telescopic rod is fixedly connected to the bottom of the inner cavity of the waterproof box body. The top of the electric telescopic rod extends through to the top of the waterproof box body and is fixedly connected to a connecting plate. It has the advantages of being able to unclog and clean the filter holes and facilitate the transportation of sludge. It solves the problem that existing dewatering devices for sludge co-firing in thermal power plants cannot unclog and clean the filter holes during use due to their simple structure. This causes the filter holes to become clogged during the sludge dewatering process, which affects the dewatering effect and makes it inconvenient to transport the dewatered sludge, thus reducing the applicability of the dewatering device.

[0004] Although the aforementioned dewatering equipment for co-firing sludge in thermal power plants has certain advantages in dewatering capacity, the equipment has two independent drive components, which increases the complexity of the control system. Simultaneous operation increases the energy consumption of the equipment, and it is inconvenient to maintain the electric telescopic rod installed inside the equipment. Utility Model Content

[0005] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a dewatering device for sludge co-firing.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a dewatering device for sludge co-firing, comprising a shell, supporting legs, a feed hopper, a discharge port, a water outlet pipe, an inclined plate, filter holes, a transmission structure, and a drying assembly.

One end of the rotating shaft is rotatably connected to the outer shell through a bearing, and the other end of the rotating shaft is drivenly connected to the agitating structure through a pulley set. The left end face of each limiting block is installed and connected to the outer shell.

The upper end of the bracket is connected to the mounting plate, the upper end of the mounting plate is provided with an unblocking needle, and the bottom right side of the bracket is equipped with connecting rods on both the front and rear sides. The connecting rods extend out of the outer shell and are fixedly connected to the movable frame.

[0008] Optionally, the agitation structure includes a motor, a rotating shaft, and an agitator.

[0013] The beneficial effects of this utility model are:

[0014] This utility model relates to a dewatering device for sludge co-firing. By setting up a transmission structure, the motor is controlled to operate. The output end of the motor drives the rotating shaft to rotate, which in turn drives the agitator to rotate. Simultaneously, the rotating shaft drives the rotating block to rotate through a belt pulley set. The rotating shaft drives the circular block to move through a connecting rod, which in turn drives the movable frame to move.

[0028] Third, while the rotating shaft 892 drives the agitator 893 to move, the rotating shaft 892 drives the rotating shaft 87 to rotate through the belt pulley group 88. The rotating shaft 87 drives the connecting rod 86 to rotate, and the connecting rod 86 drives the circular block 85 to move. The circular block 85 pushes the movable frame 81 to move.
