Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to a sludge treatment and sludge washing device. Background Art

[0002] During the sludge treatment process, sludge typically contains a large amount of water, impurities, and harmful substances. Direct treatment is not only inefficient but may also cause secondary pollution to the environment. Therefore, preliminary cleaning of sludge is a critical step in the sludge treatment process. Preliminary cleaning can remove most impurities and excess dirt from the sludge, providing cleaner and more uniform sludge for subsequent treatment steps (such as dehydration, incineration, or landfill), thereby improving overall treatment efficiency and effectiveness.

[0003] Traditional sludge cleaning devices often use simple stirring or immersion methods, which have limited cleaning effects and are difficult to completely remove impurities and harmful substances in the sludge.

[0004] Due to the relatively primitive cleaning method, the processing time is long and the efficiency is low, which cannot meet the needs of large-scale sludge treatment. Utility Model Content

[0005] The utility model aims at the technical problems existing in the prior art and provides a sludge treatment and sludge washing device to solve the problems of poor cleaning effect and low efficiency of the above-mentioned traditional sludge cleaning devices.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the mud washing cage includes a frame cage body and a mud net arranged around the frame cage body.

[0012] A motor drive connected to the drive shaft.

[0013] Furthermore, the load-bearing wheels are provided in two groups, upper and lower, along the mud inlet of the mud washing cage. The load-bearing wheels of the upper group cooperate with the inner ring of the frame cage, and the load-bearing wheels of the lower group cooperate with the outer ring of the frame cage.

[0014] Furthermore, the mud washing cage body is hinged with a cage door and a door lock for locking the cage door.

[0015] Furthermore, the spray assembly includes water supply pipes arranged opposite to each other on both sides, a plurality of spray pipes are connected between the two groups of water supply pipes, and a plurality of nozzles facing the mud washing cage are provided on the spray pipes.

[0016] Furthermore, the motor drive component is assembled from a motor and a reducer, the output end of the motor is connected to the input end of the reducer, and the output end of the reducer is connected to the drive shaft.

[0017] Moreover, the sludge treatment and washing device provided by the present invention has at least the following beneficial effects compared with the prior art:

[0018] This sludge treatment and washing device utilizes a rotating sludge washing cage and spray assembly within a top-opening sludge washing tank to achieve uniform sludge distribution, comprehensive cleaning, and dehydration. Sludge enters the sludge washing cage through the sludge inlet, where it is driven by a rotating mechanism and simultaneously rinsed with cleaning water from the spray assembly. The cleaned sludge and water are discharged through a sludge discharge tank and drain pipe.

[0019] The mud washing cage is composed of a frame cage and a mud net, which provides strength and stability and loads the sludge; the rotating mechanism includes a load-bearing wheel, a drive shaft and a motor drive, which drives the mud washing cage to rotate smoothly by reducing speed and increasing torque; the spray assembly consists of a water supply pipe, a spray pipe and a nozzle, and the cleaning water is sprayed onto the rotating sludge in the form of mist or column to achieve comprehensive cleaning.

[0025] It should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integrated structures. Those skilled in the art will understand the specific meanings of such terms in this patent based on specific circumstances.

[0026] like Figure 1 and Figure 2 As shown, the sludge treatment and mud washing device of the present utility model comprises a mud washing box 1 with an opening at the top, wherein a mud washing cage 2 and a rotating mechanism 3 connected to the mud washing cage 2 are arranged in the mud washing box 1; a mud inlet is reserved on one side of the mud washing cage 2; a mud discharge box 4 is connected to the bottom of the mud washing box 1, and a discharge pipe 5 is arranged at one end of the mud discharge box 4; a spray assembly 6 is also mounted on the mud washing box 1 and located directly above the mud washing cage 2.

[0027] Sludge enters the top-opening mud washing tank 1 through the mud inlet and into the mud washing cage 2. The cage 2 is rotated by a connected rotating mechanism 3, evenly distributing the sludge within the cage and subjecting it to centrifugal force. Simultaneously, a spray assembly 6 located directly above the cage 2 sprays cleaning water onto the sludge, flushing it. The cleaned sludge and water fall through the gaps in the mud washing cage 2 into the bottom of the mud washing tank 1, where they are then discharged through the mud discharge box 4 and the drain pipe 5 at one end, completing the cleaning and dehydration of the sludge.

[0028] As an embodiment, the mud washing cage 2 includes a frame cage body and a mud net arranged around the frame cage body. The frame cage body serves as the supporting structure of the mud washing cage 2, providing the necessary strength and stability, while the mud net plays a key role in loading sludge and allowing washing water to pass through.

[0034] Specifically, the cage body of the mud washing cage 2 is further hinged with a cage door 2.1 and a door lock for locking the cage door 2.1, so as to facilitate cleaning of residual impurities after cleaning.

[0035] Specifically, the motor drive component 3.3 is assembled from a motor and a reducer, the output end of the motor is connected to the input end of the reducer, and the output end of the reducer is connected to the drive shaft 3.2, driving the mud washing cage 2 to rotate smoothly by reducing speed and increasing torque.

[0036] As an embodiment, the spray assembly 6 includes water supply pipes arranged opposite to each other on both sides, a plurality of spray pipes are connected between the two groups of water supply pipes, and a plurality of nozzles facing the mud washing cage 2 are provided on the spray pipes.

[0037] The cleaning water flows from the water supply pipe into the spray pipe and is sprayed onto the rotating sludge in a mist or column form through the nozzle. Due to the rotation of the mud washing cage 2, the sludge is continuously washed by the cleaning water from different directions and angles, thereby achieving comprehensive cleaning of the sludge.
