[0033] As Figure 1 , Figure 2 , Figure 3 , andFigure 6 As shown, this embodiment proposes a high-efficiency sludge cell-wall breaking device, including a cell-wall breaking chamber 1 and a steam assembly 5. A discharge pipe 7 is installed through the side wall of the cell-wall breaking chamber 1, and a feed pipe 2 is installed through the top of the cell-wall breaking chamber 1.

[0034] The steam assembly 5 includes a steam generator 501 located on one side of the blending box 1. The steam generator 501 is connected to a conveying assembly for supplying steam to the interior of the blending box 1. The conveying assembly is installed at the bottom of the blending box 1, and the steam conveying assembly is inserted into the interior of the blending box 1. A first heat insulation box 6 is installed at the bottom of the blending box 1 on the outside of the conveying assembly. By setting the exhaust assembly 3 and the adsorption assembly 4, exhaust can be vented outward through the exhaust assembly 3 during use, so that the interior of the blending box 1 is in a negative pressure state, thereby preventing the odor in the sludge in the blending box 1 from escaping from the feed pipe 2. The odor discharged by the exhaust assembly 3 is discharged after being adsorbed by the adsorption assembly 4, which can avoid harming the health of on-site personnel and reduce environmental pollution. During the exhaust process of the exhaust assembly 3, the excess steam in the blending box 1 will be preheated by the preheating assembly 8 to the sludge passing through the feed pipe 2, thereby improving the utilization rate of steam and reducing energy waste. The first heat insulation box 6 can keep the conveyed steam warm.

[0035] The top of the blending chamber 1 is vented by an exhaust assembly 3 located on one side of the feed pipe 2. A preheating assembly 8 connected to the exhaust assembly 3 is installed on the outside of the feed pipe 2. The top of the feed pipe 2 is vented by the preheating assembly 8. An adsorption assembly 4 that cooperates with the preheating assembly 8 is installed on the top of the blending chamber 1. The adsorption assembly 4 is equipped with adsorption particles for adsorbing odors. The adsorption assembly 4 is located on one side of the preheating assembly 8. By setting up a steam generator 501 and a conveying assembly, the steam generated by the steam generator 501 can be conveyed to the sludge inside the blending chamber 1 during use. The sludge inside the blending chamber 1 is broken down by high-temperature steam. No wall-breaking agent needs to be added during the wall-breaking process, which is more environmentally friendly. At the same time, it reduces the risk of secondary pollution of the sludge and avoids affecting the subsequent treatment of the sludge.

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, in a preferred embodiment, based on the above method, the conveying assembly further includes a distribution box 502 installed at the bottom of the blending box 1. The distribution box 502 is connected to the steam outlet of the steam generator 501 through a second connecting pipe 503. The top of the steam generator 501 is equipped with a plurality of U-shaped pipes arranged in a ring. The U-shaped pipes are used to discharge the steam in the distribution box 502 into the interior of the blending box 1. The U-shaped pipe includes an extension pipe 504 installed at the top of the distribution box 502. The end of the extension pipe 504 away from the distribution box 502 is threadedly connected to an outlet pipe 505. The side wall of the outlet pipe 505 is provided with a plurality of evenly distributed through holes 506. A filter screen 507 is installed inside the through holes 506. It should be noted that during use, the steam generator 501 will deliver high-temperature steam to the inside of the distribution box 502 through the second connecting pipe 503. At this time, the high-temperature steam inside the distribution box 502 will be delivered to the inside of the exhaust pipe 505 through the extension pipe 504. The steam entering the exhaust pipe 505 will be evenly discharged into the sludge inside the blending box 1 through multiple through holes 506. The filter screen 507 can prevent sludge from entering the inside of the exhaust pipe 505. Moreover, the threaded connection between the exhaust pipe 505 and the extension pipe 504 can be easily disassembled when cleaning is required.

[0037] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in a preferred embodiment, based on the above method, the exhaust assembly 3 further includes a first exhaust pipe 301 penetrating the top of the blending chamber 1. A fan 302 is installed at one end of the first exhaust pipe 301 located outside the blending chamber 1, and a first connecting pipe 303 is connected to the fan 302. A hemispherical filter cover 304 is installed at one end of the first exhaust pipe 301 located inside the blending chamber 1. It should be noted that during use, the fan 302 can draw away the gas inside the blending chamber 1 through the first exhaust pipe 301, making the interior of the blending chamber 1 under negative pressure, preventing the odor inside the blending chamber 1 from escaping from the feed pipe 2. The first connecting pipe 303 can transport excess steam and odor heated by steam inside the blending chamber 1 to the interior of the spiral tube 803 through the third connecting pipe 802. The filter cover 304 can prevent sludge from entering the interior of the first exhaust pipe 301.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, in a preferred embodiment, based on the above method, the preheating component 8 further includes a second heat insulation box 801 installed on the top of the blending box 1. A spiral tube 803 surrounding the outside of the feed pipe 2 is installed inside the second heat insulation box 801. A third connecting pipe 802 and a fourth connecting pipe 806 are connected to both ends of the spiral tube 803, respectively. A drain pipe 804 is installed through the third connecting pipe 802, and valves 805 are installed on both the drain pipe 804 and the discharge pipe 7. It should be noted that the steam delivered from the first connecting pipe 303 and the air heated by the steam enter the interior of the spiral tube 803 through the third connecting pipe 802 to preheat the sludge passing through the feed pipe 2, reducing the waste of heat in the steam. Simultaneously, the steam gradually condenses as it passes through the spiral tube 803, at which point the odorous gas enters the interior of the adsorption component 4 through the fourth connecting pipe 806. Opening the valve 805 on the drain pipe 804 allows the condensate in the spiral tube 803 to be discharged.

[0039] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in a preferred embodiment, based on the above method, the adsorption assembly 4 further includes an adsorption box 401 installed on top of the blending box 1. A box cover 402 is threadedly connected to the top of the adsorption box 401, and a second exhaust pipe 403 is installed through the side wall of the adsorption box 401. It should be noted that the adsorption particles filled inside the adsorption box 401 can be activated carbon. During use, the fourth connecting pipe 806 will transport the cooled odor to the interior of the adsorption box 401. After being adsorbed by the activated carbon inside the adsorption box 401, the odor is discharged through the second exhaust pipe 403, which can reduce the harm of odor to on-site personnel and the environment.

[0040] Specifically, the working principle of this high-efficiency sludge cell-wall breaking device is as follows: During use, the steam generator 501 will transport high-temperature steam to the inside of the distribution box 502 through the second connecting pipe 503. At this time, the high-temperature steam inside the distribution box 502 will be transported to the inside of the exhaust pipe 505 through the extension pipe 504. The steam entering the exhaust pipe 505 will be evenly discharged into the sludge inside the cell-wall breaking box 1 through multiple through holes 506. The sludge is broken down by the high-temperature steam. During the cell-wall breaking process, the blower 302 can draw away the gas in the cell-wall breaking box 1 through the first exhaust pipe 301 to keep the inside of the cell-wall breaking box 1 under negative pressure, preventing the odor in the cell-wall breaking box 1 from escaping from the feed pipe 2. At the same time, when sludge is transported into the cell-wall breaking box 1 through the feed pipe 2, the exhaust component 3 can also be activated to maintain the negative pressure inside the cell-wall breaking box 1, preventing the odor in the sludge from escaping. Odor dissipation is achieved by using the first connecting pipe 303 to transport excess steam and steam-heated odor from the blending chamber 1 to the spiral tube 803 via the third connecting pipe 802. This preheats the sludge passing through the feed pipe 2, reducing heat waste in the steam. Simultaneously, the steam gradually condenses as it passes through the spiral tube 803. The cooled odor then enters the adsorption chamber 401 via the fourth connecting pipe 806. After being adsorbed by the activated carbon inside the adsorption chamber 401, it is discharged through the second exhaust pipe 403, reducing the harm of odor to on-site personnel and the environment. During the use of the device, the outlet pipe 505, which is threaded onto the extension pipe 504, should be disassembled periodically for cleaning of its interior and the filter screen 507. This effectively prevents blockage of the outlet pipe 505 and the through hole 506.

[0041] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
