Description

Technical Field

[0001] This utility model relates to the technical field of integrated dewatering and drying devices for municipal sludge, and in particular to an integrated dewatering and drying device for municipal sludge. Background Technology

[0002] With the acceleration of urbanization and the continuous improvement of sewage treatment capacity, the production of municipal sludge is also showing a rapid growth trend. Municipal sludge is a byproduct of sewage treatment, characterized by high water content, high organic matter content, easy decomposition, easy emission of foul odor, and the presence of pathogenic microorganisms and heavy metals. If not properly treated, it will cause serious secondary pollution to water bodies, soil, and the atmosphere. Therefore, the reduction, harmlessness, and resource utilization of sludge have become important issues in urban environmental governance. In the municipal sludge treatment process, dewatering and drying are two key steps. Currently, commonly used sludge treatment equipment mainly includes plate and frame filter presses, belt filter presses, centrifugal dewatering machines, paddle dryers, and drum dryers. Although these methods have achieved sludge reduction to a certain extent, most current sludge treatment systems treat dewatering and drying as two independent steps, configuring different equipment for each. This results in a complex system process, a large number of devices, and the need for transportation, increasing construction and operating costs.

[0003] Therefore, it is necessary to design an integrated municipal sludge dewatering and drying device to solve the above problems. Utility Model Content

A support frame 15 is fixedly connected to the bottom of the drying tank 14 by bolts. A hot cavity 16 is opened inside the drying tank 14. Heaters 17 are fixedly connected to the left and right sides of the hot cavity 16 by bolts. A discharge pipe 181 is fixedly connected to the front of the drying tank 14, and a pump body 18 is installed on the discharge pipe 181. A second motor 22 is fixedly connected to the top of the drying tank 14 by bolts. A stirring shaft 23 is fixedly connected to the bottom output shaft of the second motor 22. The stirring shaft 23 is located inside the drying tank 14.

[0022] like Figure 1 and Figure 3 As shown, it also includes a water storage tank 9, and the bottom of the collection frame 6 is fixedly connected to the water storage tank 9.

[0023] like Figure 3As shown, it also includes a discharge pipe 10, a second filter screen 11, and a filter box 12. The discharge pipe 10 is fixedly connected to the front side of the water storage tank 9, the second filter screen 11 is fixedly connected to the rear inner side of the discharge pipe 10, and the filter box 12 is fixedly connected to the front inner side of the discharge pipe 10.

[0024] like Figure 1 and Figure 4 As shown, it also includes an annular frame 19 and an inlet pipe 20.

[0027] When this device is needed to dewater and dry municipal sludge, the first motor 4 is started, driving the compression shaft 3 to rotate, initiating the mechanical pressing and dewatering process of the sludge. The sludge is fed through the inlet pipe 5 and enters the dewatering tank 1, where it is squeezed by the compression shaft 3. Water flows through the outlet trough into the collection frame 6. The first filter screen 7 and filter cotton 8 in the collection frame 6 perform secondary purification of the filtrate before it enters the storage tank 9.

The second motor 22 is started, and the stirring shaft 23 rotates under the drive of the second motor 22, causing the stirring shaft 23 to agitate the sludge, ensuring even heating and accelerating water evaporation. The scraper 24 scrapes off the attached material. Sludge is scraped off the inner wall of the drying barrel 14 to prevent it from adhering to the inner wall and ensure smooth operation of the equipment. Evaporated water vapor rises into the annular frame 19 and then enters the water storage tank 9 through the inlet pipe 20. The fixing frame 21 fixes the inlet pipe 20 to make it more stable. After drying, the container can be placed directly below the discharge pipe 181. The pump body 18 on the discharge pipe 181 is started to discharge the dried material into the container. Then the pump body 18 is turned off. Throughout the process, harmful gases in the liquid in the water storage tank 9 are purified by the second filter screen 11 and the filter box 12 on the front side and then discharged. The operator then connects the discharge pipe 10 to extract the liquid in the water storage tank 9 for treatment. After the sludge is treated, the first motor 4, heater 17 and second motor 22 are turned off.
