Technical Field

[0001] The utility model belongs to the technical field of municipal engineering, and in particular relates to a municipal sludge treatment device. Background Art

[0002] With the continuous development of urbanization in my country, the discharge of urban industrial wastewater and domestic sewage is increasing day by day. A large amount of sludge will be generated in urban sewage rivers, underground pipes and sewage treatment plants. A huge amount of sludge needs to be further treated. The sludge contains rich organic matter and nutrients such as N, P, and K. If it is not handled properly, it will not only easily cause environmental pollution, but also waste resources. At present, when treating municipal sludge, the sewage is generally piled up and naturally dehydrated, and then transported for utilization. In the process of sludge treatment, many sludges will contain large and difficult-to-decompose garbage. Because the sludge is relatively viscous, the garbage contained in it is not easy to be separated, resulting in a time-consuming and labor-intensive garbage removal work. In the process of filtering the garbage, the sludge is very easy to clog the filtering mechanism, resulting in low efficiency in removing the garbage in the sludge. Utility Model Content

[0003] The utility model provides a municipal sludge treatment device, which can filter sludge, disperse and dilute the sludge during the filtering process, so as to avoid the sludge being too thick and wrapping garbage inside it. During the treatment process, the sludge and garbage cannot be separated, resulting in greater difficulty in sludge treatment, causing clogging of the filter plate during the filtering process, affecting the treatment effect and efficiency.

[0005] Wherein, a material guide platform is arranged inside the material outlet, one end of the material guide platform is connected to one end of the filter plate, and the top of the material guide platform is arranged as an inclined structure.

[0006] Wherein, a connecting shaft is arranged at one end of the rotating drum, and one end of the connecting shaft passes through one side of the outer shell and is connected to the output end of the driver.

[0018] In this embodiment: the new type is provided with an outer shell 1, a top plate 11, and a liquid inlet pipe 12 to form an external frame structure of this device, and a rotating drum 2 is provided, and a plurality of filter screens 21 are provided on the edges thereof. When the sludge enters the inner cavity of the outer shell 1 through the liquid inlet pipe 12, it first falls on the top of the rotating drum 2, and the rotating drum 2 is driven to rotate by the driver 22. During the rotation process, the plurality of filter screens 21 disperse the sludge, so that the sludge with greater viscosity is dispersed, and the garbage wrapped in the sludge can be exposed after the sludge is dispersed. The dispersed sludge continues to fall on the filter plate 3, and starts to slide from the higher end of the filter plate 3 to the lower end. During the sliding process of the sludge, the stepped filter plate 3 causes the sludge to have multiple downward impact forces during the sliding process. Through the downward force, each time the sludge passes through a screen 31, the effect of the screen 31 on filtering impurities inside the sludge is increased, and the sludge is prevented from entraining the garbage through the screen. 31 slides directly to the lower end. By setting a cleaning pipe 4, in the process of filtering the garbage inside the sludge through the filter plate 3, the cleaning pipe 4 is used to spray the sludge to dilute it, so as to prevent the sticky sludge from blocking the screen 31, so that the garbage in the sludge is filtered out, and the filtered garbage moves to the discharge port 14 after passing through one end of the filter plate 3, and falls to the outside of the outer shell 1 through the guide platform 15 set in the discharge port 14. The sludge diluted by the water flushed out by the cleaning pipe 4 falls to the bottom of the inner cavity of the outer shell 1 through the screen 31, and is discharged through the drain pipe 16, thereby completing the effect of the garbage process inside the sludge, so that the new type can filter the sludge, disperse and dilute the sludge during the filtration process, so as to prevent the sludge from being too thick and wrapping the garbage inside it. During the treatment process, the sludge and the garbage cannot be separated, resulting in greater difficulty in sludge treatment, clogging the filter plate during the filtration process, affecting the treatment effect and efficiency.

[0019] A material guide platform 15 is provided inside the discharge port 14, one end of the material guide platform 15 is connected to one end of the filter plate 3, and the top of the material guide platform 15 is set as an inclined structure; by setting the material guide platform 15, the garbage filtered out of the filter plate 3 is guided, so that the garbage moves along the inclined surface of the top of the material guide platform 15 to the outside of the outer shell 1.

[0020] A connecting shaft 23 is provided at one end of the rotating drum 2, and one end of the connecting shaft 23 passes through one side of the outer shell 1 and is connected to the output end of the driver 22; by providing the connecting shaft 23, the rotating drum 2 is connected to the output end of the driver 22, and the rotating drum 2 is driven by the driver 22.

[0021] The filter plate 3 is arranged in a stepped shape, and a plurality of screens 31 are arranged at equal intervals from top to bottom, and protrusions 32 are arranged at both ends of the filter plate 3, and limit blocks 33 for limiting the protrusions 32 are arranged on the inner walls of both sides of the outer shell 1; by arranging the filter plate 3 in a stepped shape, the sludge is subjected to a downward impact force multiple times during the sliding process, and the downward force increases the effect of the screen 31 on filtering impurities inside the sludge every time the sludge passes through a screen 31.

[0022] A drain pipe 16 is provided at one end of the outer shell 1, and one end of the drain pipe 16 is connected to the bottom of the inner cavity of the outer shell 1; by providing the drain pipe 16, it is convenient to discharge the filtered sludge in the inner cavity of the outer shell 1, so that the sludge and garbage are separated and discharged.

[0023] The working principle and use process of the utility model are as follows: when in use, the sludge is discharged into the interior of the outer shell 1 through the liquid inlet pipe 12. When the sludge enters the inner cavity of the outer shell 1 through the liquid inlet pipe 12, it first falls on the top of the rotating drum 2, and the rotating drum 2 is driven to rotate by the driver 22. During the rotation process, a plurality of filter screens 21 disperse the sludge, so that the sludge with greater viscosity is dispersed, and the garbage and the like wrapped in the sludge can be exposed after the sludge is dispersed. The dispersed sludge continues to fall onto the filter plate 3, and starts to slide from the higher end of the filter plate 3 to the lower end. During the sliding process of the sludge, the stepped filter plate 3 causes the sludge to impact downward multiple times during the sliding process, and the downward force causes the sludge to flow downward each time. When passing through a screen 31, the effect of the screen 31 on filtering impurities inside the sludge is increased, and the sludge is prevented from sliding directly to the lower end through the screen 31 with the garbage. By setting a cleaning pipe 4, in the process of filtering the garbage inside the sludge through the filter plate 3, the sludge is sprayed through the cleaning pipe 4 to dilute it, and the sticky sludge is prevented from blocking the screen 31, so that the garbage in the sludge is filtered out, and the filtered garbage moves to the discharge port 14 after passing through one end of the filter plate 3, and falls to the outside of the outer shell 1 through the guide table 15 set in the discharge port 14. The sludge diluted by the water flushed out by the cleaning pipe 4 passes through the screen 31 and falls to the bottom of the inner cavity of the outer shell 1, and is discharged through the drain pipe 16, thereby completing the effect of the garbage process inside the sludge.
