Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, specifically to a bottom sludge drying device for sewage treatment. Background Technology

[0002] Currently, wastewater sludge drying is a process aimed at removing most of the water content from sludge, mainly achieved through processes such as percolation or evaporation. Various methods exist for sludge drying, including natural evaporation and mechanical dewatering. Mechanical dewatering is more commonly referred to as sludge dewatering, while natural evaporation is called sludge drying. Sludge drying technology also includes the use of sludge dryers, which are indirect heating, low-speed stirring dryers characterized by energy saving and high thermal efficiency.

[0003] Currently, in the process of low-temperature sludge drying, the drying efficiency is relatively low due to the high humidity, and the required cycle is long. Moreover, the moisture inside the sludge is easily blocked by the surface, and the bottom cannot come into contact with air, which further reduces the drying efficiency. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a bottom sludge drying device for sewage treatment, comprising:

[0021] A sewage frame 1 is provided, and a heating frame 2 is fixedly embedded in the inner wall of the sewage frame 1. A support rod 3 is fixedly provided at the top center of the heating frame 2.

[0022] A stable connection structure is provided on the support rod 3 and the sewage frame 1;

[0023] The stable connection structure includes a connecting sleeve 4, a main pulley 5, a fixing frame 6, and a connecting plate 7. The inner wall of the connecting sleeve 4 is rotatably fitted onto the support rod 3. One end of the fixing frame 6 is fixedly embedded in the sewage frame 1, and the other end of the fixing frame 6 is fixedly fitted onto the support rod 3. One end of the connecting plate 7 is fixedly fitted onto the support rod 3, and the other end of the connecting plate 7 is fixedly embedded into the sewage frame 1. The bottom of the outer wall of the main pulley 5 is fixedly fitted onto the connecting sleeve 4, the outer surface of the main pulley 5 is rotatably fitted into the fixing frame 6, and the inner wall of the main pulley 5 is rotatably fitted onto the support rod 3.

[0024] In this implementation plan: sewage can be stored in the sewage frame 1 and the sewage can be settled to produce sludge. By heating the inside of the heating frame 2, heat is generated in the heating frame 2, which in turn generates heat at the bottom of the sludge to evaporate the water. The fixed frame 6 and the connecting plate 7 can stably support the support rod 3 at the center, making the rotation more stable. The main pulley 5 drives the connecting sleeve 4 to rotate around the support rod 3.

[0025] Specifically, a rotating sleeve 8 is fixedly provided at the bottom of the outer wall of the connecting sleeve 4, and the inner wall of the rotating sleeve 8 is rotatably sleeved on the support rod 3.

[0026] In this embodiment, the rotating sleeve 8 is fixed on the connecting sleeve 4 and rotates with it.

[0027] Specifically, two mud-stirring plates 9 are fixedly provided on the outer wall of the rotating sleeve 8, and the two mud-stirring plates 9 are set at equal distances along the circumferential surface.

[0028] In this embodiment, two stirring plates 9 are fixed on the rotating sleeve 8 to turn the sludge over, so that the sludge at the bottom moves to the top, thereby increasing the contact area and increasing the drying efficiency.

[0029] Specifically, a control motor 10 is installed on the top of the outer wall of the sewage frame 1, and a secondary pulley 11 is fixedly fitted on the output end of the control motor 10.

[0030] In this embodiment, the output of the motor 10, when energized, drives the auxiliary pulley 11 to rotate.

[0031] Specifically, the outer wall of the auxiliary pulley 11 is rotatably embedded in the fixed frame 6.

[0032] In this embodiment, the auxiliary pulley 11 rotates within the fixed frame 6 to provide protection.

[0033] Specifically, a transmission belt 12 is wound between the auxiliary pulley 11 and the main pulley 5.

[0034] In this embodiment, the auxiliary pulley 11 and the main pulley 5 can be connected by the transmission belt 12 to provide a power connection.

[0035] In use, the wastewater frame 1 stores wastewater and allows it to settle, producing sludge. Heating the interior of the heating frame 2 generates heat, which in turn heats the bottom of the sludge, evaporating moisture. The fixed frame 6 and connecting plate 7 stably support the support rod 3 at its center, ensuring stable rotation. The main pulley 5 drives the connecting sleeve 4 to rotate around the support rod 3. The rotating sleeve 8, fixed to the connecting sleeve 4, rotates with it. Two sludge-stirring plates 9, fixed to the rotating sleeve 8, tumble the sludge, moving the bottom sludge to the top, increasing the contact area and drying efficiency. The auxiliary pulley 11 rotates within the fixed frame 6 for protection. The transmission belt 12 connects the auxiliary pulley 11 and the main pulley 5, providing a power connection and a stable structure. This ensures stable rotation around the center and tumbles the sludge, moving the bottom sludge to the top, increasing the contact area and drying efficiency.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
