Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to an auxiliary device for sludge unloading. Background Technology

[0002] Sludge is a byproduct of wastewater treatment, containing large amounts of water and organic matter. Improper handling can have negative environmental impacts. Sludge drying is a technology that reduces the water content of sludge through physical or chemical methods, reducing volume, facilitating transportation, and creating conditions for subsequent resource utilization. The core objective of sludge drying is to remove moisture, typically reducing the water content from around 80% to below 30%. Current conventional drying methods involve a conveyor transporting wet sludge to a sludge drying tank. Canvas bags are attached to the conveyor outlet as a connecting component, and the bags are cut to the required height from the conveyor outlet to the drying tank. The wet sludge then enters the drying tank through these canvas bags. This entire operation is time-consuming and cumbersome. In practical applications, it has been found that the lid of the sludge drying tank easily rubs against the canvas bags, causing damage. During feeding, leakage of wet sludge may also occur, requiring dedicated personnel to monitor and promptly clean up any significant leaks. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an auxiliary device for sludge unloading.

[0004] The objective of this utility model is achieved through the following technical solution: A sludge unloading auxiliary device includes a liner plate installed at the unloading port. A retractable canvas connecting assembly is connected to the liner plate through a sealing cover. The canvas connecting assembly includes a canvas channel with upper and lower openings connected together. A telescopic component is connected to the inner side of the canvas channel. The telescopic component is electrically connected to a PLC control component.

[0005] Preferably, the telescopic assembly includes a telescopic support steel column, the upper end of which is connected to a sealing cover.

[0006] Preferably, the telescopic support steel column consists of a sleeve-type steel column and a pulley system placed between the steel columns, and the telescopic support steel column extends or retracts to drive the canvas channel to unfold or fold.

[0007] Preferably, the canvas channel is a three-proof canvas channel.

[0008] Preferably, the liner and the discharge port are connected by a snap-fit ​​connection.

[0009] The beneficial effects of this invention are as follows: the height of the canvas channel can be adjusted according to the height between the discharge port of different drying tanks and conveyors, thus having higher adaptability. Because the canvas channel is stably supported by supporting steel columns, wear is reduced, leakage of wet sludge is minimized, service life is extended, and sludge treatment costs are saved. Attached Figure Description

[0010] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0013] This utility model discloses a sludge unloading auxiliary device, combined with Figure 1 and Figure 2 As shown, the device is used to assist sludge in smoothly entering the drying tank during the treatment process. The device is typically connected to the discharge port of the conveyor, serving as the connecting channel for the sludge to enter the drying tank from the conveyor. Using this device avoids the need for continuous manual modification of the canvas bags in existing technologies.

[0014] The sludge unloading auxiliary device includes a liner 21 installed at the discharge port 11 of the conveyor 1, and a retractable canvas connecting assembly is connected to the liner 21 below it via a sealing cover 22. In this embodiment, the liner 21 and the discharge port are connected by a snap-fit ​​connection.

[0015] The canvas connecting assembly includes a canvas channel 24 with upper and lower openings connected together. A telescopic component is connected to the inner side of the canvas channel 24, and the telescopic component is electrically connected to the PLC control component. The telescopic component can switch the canvas channel 24 between unfolding and folding by extending and retracting.

[0016] In this embodiment, the telescopic assembly includes a telescopic support steel column 23 composed of a sleeve-type steel column 24 and a pulley system 25 placed between the steel columns. The upper end of the telescopic support steel column 23 is connected to the sealing cover 22. The outer side of the telescopic support steel column 23 is connected to the canvas channel 24. For better sealing and improved service life, the canvas channel is made of three-proof canvas.

[0017] Of course, the telescopic component can also take other forms, such as a cross-type telescopic steel rod.

[0018] When sludge unloading is required, auxiliary device 2 is tightly connected to the unloading port via liner 21. The PLC control unit activates the retractable canvas connecting assembly, extending the canvas channel until its outlet reaches the inlet of the sludge drying tank 3. During unloading, once the canvas channel is fully extended, its outer wall presses tightly against the inner wall of the inlet of the drying tank 3, ensuring no exhaust gas leakage. Simultaneously, the telescopic support steel columns ensure the canvas channel remains stable during use, preventing continuous friction with the inlet of the sludge drying tank 3 and reducing damage. After unloading is complete, the PLC control unit receives a signal and controls the retraction of the canvas connecting assembly, folding and retracting the canvas channel for the next unloading operation.
