A rotating cover plate is hinged to the outer wall of the aging tank to cover the sludge outlet. The bottom end of the rotating cover plate is rotatably connected to the bottom side wall of the aging tank. A guide plate extends from the side of the rotating cover plate near the aging tank, conforming to the inner side wall of the aging tank. A drive device is fixedly installed on the top wall of the aging tank to drive the rotating cover plate to open and close. This achieves the effect of allowing sludge to be stably discharged through the sludge outlet without additional extraction and transfer processes, effectively improving the transfer efficiency of the device.

Description

Technical Field

[0001] This utility model relates to the technical field of sludge brick making, specifically to an aging device for sludge treatment. Background Technology

[0002] Sludge contains a large amount of organic matter and abundant nutrients such as nitrogen and phosphorus. Its indiscriminate discharge into water bodies will deplete oxygen, leading to water quality deterioration and severely impacting the survival of aquatic life. Furthermore, sludge contains various toxic substances, heavy metals, pathogens, parasite eggs, and other harmful substances. Improper handling can spread diseases, pollute soil and crops, and ultimately affect humans through the food chain. Therefore, the indiscriminate discharge and stockpiling of untreated sludge will inevitably cause serious pollution to the surrounding environment, preventing existing wastewater treatment plants from fully fulfilling their role in pollution control. Comprehensive utilization of sludge involves treating it to achieve volume reduction, stabilization, and harmlessness before utilizing it. Comprehensive utilization of sludge is of great significance for the rational use of resources and the reduction of environmental pollution. Examples of comprehensive sludge utilization include: use in farmland and forestry, and application in building materials.

[0003] In the existing sludge brick-making process, a very important step is to introduce the sludge into an aging tank for a period of time to age. The aging tank is generally a square structure made of concrete and buried in the ground. After aging, the sludge cannot be directly dumped and needs to be extracted and transported using other equipment. The sludge transportation efficiency after aging is low. Utility Model Content

[0004] The purpose of this invention is to provide an aging device for sludge treatment.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The aging chamber includes an opening on its top wall along the direction of gravity, a sludge outlet on a cut-off side wall, a hinged rotating cover that covers the sludge outlet on the outer wall of the aging chamber, a bottom rotatably connected to the bottom side wall of the aging chamber, a guide plate extending from the side of the rotating cover near the aging chamber that fits against the inner side wall of the aging chamber, and a drive device for opening and closing the rotating cover that is fixedly installed on the top wall of the aging chamber.

[0007] By adopting the above technical solution, the sludge outlet of the aging tank is cut off. When the rotating cover is removed, the sludge in the aging tank can flow out naturally from high to low through the sludge outlet. It is only necessary to align the subsequent equipment for receiving the aged sludge with the sludge outlet for automatic reception. There is no need for an additional extraction and transfer process, which effectively improves the set transfer efficiency. At the same time, the folding rotating cover combined with the guide plate forms a good transfer path, which plays a good guiding role in the sludge transfer process and prevents splashing and overflow that would cause waste.

[0008] Furthermore, the driving device includes a drive motor, which is fixedly mounted on the top wall of the aging tank. A winch is fixedly sleeved on the rotating shaft of the drive motor, and a winch rope is fixedly installed on the winch. The end of the winch rope is fixedly connected to the top of the rotating cover plate.

[0009] By adopting the above technical solution, when the winch is released, the rotating cover opens naturally under the push of the sludge. After the rotating cover rotates to the specified angle, the sludge flows naturally on the rotating cover and is input into the specified position. After the sludge discharge and transfer are completed, the drive motor is started to tighten the winch, which can drive the rotating cover to close again, and sludge can be filled again for aging.

[0010] Furthermore, the bottom wall of the aging box is tilted to the side, with the end of the bottom wall of the aging box away from the rotating cover being higher than the end of the bottom wall of the aging box near the rotating cover.

[0011] By adopting the above technical solution, the aging tank with its tilted bottom wall can allow the sludge to slide off automatically under gravity, preventing the sludge from sticking to the bottom and accumulating in large quantities, which helps to thoroughly drain all the sludge from the aging tank.

[0012] Furthermore, a pair of sludge baffles are fixedly connected to the outer wall of the aging box. The sludge baffles are sandwiched on both sides of the rotating cover and are attached to the side wall of the rotating cover.

[0013] By adopting the above technical solution, the sludge baffle can effectively prevent sludge from overflowing from the edge of the rotating cover when the sludge baffle is opened.

[0014] Furthermore, the sludge baffle is an arc-shaped plate, and a limiting plate is fixedly connected to the end of the sludge baffle away from the aging tank. Different sludge baffles are respectively connected to the two ends of the limiting plate.

[0015] By adopting the above technical solution, the setting of the limiting plate can effectively limit the rotation angle of the rotating cover, prevent the rotating cover from rotating too much and causing a large amount of sludge to gush out in a short time, and improve the overall strength of the equipment.

[0016] In summary, the beneficial technical effects of this utility model are as follows:

[0017] 1. It adopts a sludge outlet, rotating cover plate and guide plate, so that the sludge can be stably discharged out of the sludge outlet without the need for an additional extraction and transfer process, which effectively improves the transfer efficiency of the system.

[0018] 2. It adopts a drive motor, winch, and rope to achieve the effect of autonomously controlling the opening and closing of the rotating cover.

[0019] 3. The bottom wall is tilted to prevent sludge from sticking to the bottom and accumulating in large quantities, thus ensuring that all sludge in the aging tank is completely drained. Attached Figure Description
