Description

Technical Field

[0001] This utility model relates to sludge treatment equipment, specifically to a washing drum used in a pipeline sludge treatment system. Background Technology

[0002] With the increasing efforts in urban sewage and industrial wastewater treatment, the issue of sludge treatment and disposal has become increasingly prominent. Sludge from pipework, collected during the dredging and cleaning of drainage pipelines, contains particulate matter, impurities, road dust, garbage, and mud from construction sites. Currently, sludge is mainly disposed of by transporting it to landfills after sludge removal or mixing it with construction waste. However, this process is costly and prone to causing serious odor and secondary pollution. Simple landfilling has a significant impact on the ecological environment and occupies a large amount of land resources. Therefore, there is a need for equipment that can efficiently treat sludge from pipework to achieve sludge reduction, stabilization, harmlessness, and resource utilization. Utility Model Content

[0003] The purpose of this invention is to provide a washing drum for use in pipeline sludge treatment systems, in order to solve the problems existing in the current pipeline sludge treatment process. This washing drum is installed inclined upwards along its axis on the ground, effectively separating large particulate impurities from the sludge and achieving preliminary sludge treatment and volume reduction, thus facilitating subsequent treatment processes.

[0004] To achieve the above objectives, this utility model is implemented as follows:

[0005] A washing drum for use in a sewer sludge treatment system includes:

[0006] The sealed outer frame (1) is rectangular in shape and has an internal cavity;

[0007] A washing drum body (2) with a circular hole (21) is set in the receiving cavity of the outer frame (1). The diameter of the circular hole (21) is 10 mm. The washing drum body (2) is set on the ground with its axis inclined upward, and its inner wall is provided with a spiral structure (22).

[0008] The washing drum drive motor (3) is connected to the washing drum body (2) and is used to drive the washing drum body (2) to rotate;

[0009] A rinsing rod (4) with rinsing nozzles (41) is disposed inside the washing drum body (2) and extends along the axial direction of the washing drum body (2). A plurality of rinsing nozzles (41) are evenly distributed in a ring on the rinsing rod (4), and the spraying direction of the rinsing nozzles (41) is toward the inner wall of the washing drum body (2).

[0010] The feed inlet (6) is located at one end of the outer frame (1) and is connected to the front end of the washing drum body (2) for feeding sludge with large particles of impurities.

[0011] The discharge port (7) is located at the other end of the outer frame (1) and is connected to the rear end of the washing drum body (2) for discharging large particles of material after treatment.

[0012] The flushing water inlet (8) is set on the outer frame (1) and connected to the flushing rod (4) for inputting flushing water into the flushing rod (4);

[0013] The drain outlet (5) is located at the bottom of the outer frame (1) and is used to drain the rinsing water and the impurities that are rinsed off.

[0014] When the equipment is started, the washing drum body (2) rotates and washes the sludge with large particles of impurities that enters from the front feed port (6). Under the action of the spiral structure (22), the sludge is gradually transported to the large particle material discharge port (7). During this process, the washing nozzle (41) washes the sludge without dead angles, so that the large particles of material discharged from the discharge port (7) are clean and odorless. The washing water and the impurities washed off are discharged to the subsequent sand washing machine through the sewage outlet (5) at the bottom of the equipment. The equipment is a fully enclosed device with no odor leakage.

The inspection door (11) can be sealed and closed to facilitate equipment maintenance and repair. The observation window (12) is made of transparent corrosion-resistant material, which allows operators to observe the internal operation of the equipment in real time and ensure the safe and stable operation of the equipment. The two ends of the washing drum body (2) are connected to the outer frame (1) through bearings (9) and sealing covers (10) respectively. The bearings (9) are sealed bearings, which can effectively prevent sludge and water from entering and ensure the flexibility and stability of rotation. The sealing cover (10) adopts a multi-layer sealing structure, which further enhances the sealing performance of the equipment and prevents odor leakage and sewage seepage.

[0019] The washing drum used in the pipeline sludge treatment system has a gradually decreasing pitch of the spiral structure (22), which causes the sludge to be gradually squeezed during transportation, further reducing the water content of the material and improving the dewatering effect of the sludge, which is beneficial to subsequent treatment and disposal. The flushing nozzle (41) is an adjustable nozzle, and its spray angle and spray intensity can be adjusted according to the properties of the sludge and the treatment requirements to achieve the best flushing effect, ensuring that the impurities in the sludge can be thoroughly flushed off and improving the cleanliness of the material.

The control system is connected to the washing drum drive motor (3), the flushing nozzle (41) and related sensors. It can automatically control the operating parameters of the equipment, such as the drum speed, flushing water volume, and flushing water pressure, to achieve intelligent and automated operation, improve the operating efficiency and stability of the equipment, and reduce the intensity and error of manual operation. The sewage outlet (5) is equipped with a filter device, which can perform preliminary filtration of the discharged sewage and impurities to prevent large particles of impurities from clogging the pipes and ensure the smooth flow of sewage. It is also conducive to the normal operation of the subsequent sand washing machine and improves the efficiency and reliability of the entire sludge treatment system.

[0021] The washing drum used in the pipeline sludge treatment system described above is also provided with a support foot (13) at the bottom of the equipment. The support foot (13) is height adjustable to ensure stable placement and installation of the equipment and to adapt to different installation sites and conditions.

During this process, the washing nozzle 41 washes the sludge without dead angles, so that the large particles of material discharged from the discharge port 7 are clean and odorless. The washing water and the impurities washed off are discharged to the subsequent sand washing machine through the sewage outlet 5 at the bottom of the equipment. The entire equipment is a fully enclosed device with no odor leakage.
