[0020] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0021] The following describes an anti-leakage and antibacterial container for a sludge storage and transportation system according to an embodiment of the present invention with reference to the accompanying drawings.

[0022] like Figure 1 , 2As shown, an embodiment of the present invention proposes a leak-proof and antibacterial container for a sludge storage and transportation system, comprising: a box body and a cover body, the interior of the box body is provided with a chamber, the top of the chamber is provided with a feed port, the top of the chamber is provided with an ozone generating unit 1, the side wall of the chamber is provided with an ultraviolet lamp 7 for irradiating and sterilizing the sludge, and the bottom of the chamber is paved with a copper-loaded zeolite adsorption layer 8; the cover body is pluggable and connected to the feed port, and the cover body and the feed port are sealed.

[0023] The embodiment of the present invention can improve the antibacterial function of the container by providing an ozone generating unit 1, an ultraviolet lamp 7 and a copper-loaded zeolite adsorption layer 8, avoid the risk of explosion of harmful gases such as hydrogen sulfide produced by sludge corruption, avoid secondary pollution caused by the continuous reproduction of pathogenic microorganisms during transportation, and reduce the risk of cross contamination during loading and unloading.

[0024] The anti-leakage and antibacterial container for the sludge storage and transportation system according to the embodiment of the present invention can be applied to sludge storage and transportation operations in sewage treatment plants, chemical plants and other scenarios.

[0025] Furthermore, when the ozone generating unit 1 is working, the ozone concentration in the box is controlled at 50-200 ppm.

[0026] Furthermore, the feed inlet is located at the center of the box.

[0027] In some embodiments, Figure 2 As shown, the box body is a composite layer structure, including a stainless steel corrugated plate 9, a basalt fiber reinforced epoxy resin layer 10 and an antibacterial lining layer 11. The stainless steel corrugated plate 9 is located at the outermost layer of the box body, the basalt fiber reinforced epoxy resin layer 10 is located at the middle layer of the box body, and the antibacterial lining layer 11 is located at the innermost layer of the box body.

[0028] By providing a stainless steel corrugated plate 9 on the outer layer of the box, the performance of the outer part of the box against mechanical impact can be improved. By providing a basalt fiber reinforced epoxy resin layer 10 on the middle layer of the box, a temperature deformation compensation function is provided to prevent the box from deforming due to temperature changes. By providing an antibacterial lining layer 11 on the inner layer of the box, a large number of bacteria in the sludge can be prevented from adhering to the box.

[0029] Furthermore, the stainless steel corrugated plate 9 is a 304 stainless steel corrugated plate.

[0030] In some embodiments, the lining antibacterial layer 11 includes a PTFE coating and a nano-silver antibacterial layer, and the PTFE coating is located at the innermost layer of the box. By providing the PTFE coating, the sludge can be prevented from chemically corroding the box.

[0031] In some embodiments, Figure 1As shown, the cover body includes an outer cover plate 5, an insert plate 3 and a rubber baffle plate 2. The insert plate 3 is fixedly connected between the outer cover plate 5 and the rubber baffle plate 2. The outer diameter of the outer cover plate 5 and the outer diameter of the rubber baffle plate 2 are both larger than the diameter of the feed port. When the cover body covers the feed port, the outer cover plate 5 is located outside the box body, and the rubber baffle plate 2 is located inside the chamber and closely fits the edge of the feed port. The sealing performance of the container can be improved to prevent the leakage of leachate and contamination of the transportation path.

[0032] It should be noted that the rubber baffle 2 is elastic. When the cover is inserted into the feed port, the rubber baffle 2 is squeezed. When the rubber baffle 2 completely enters the interior of the chamber, the rubber baffle 2 unfolds, returns to its original shape, and adheres to the feed port to seal it.

[0033] Furthermore, the rubber baffle 2 is a labyrinth-type rubber baffle 2, which can improve the sealing performance.

[0034] In some embodiments, Figure 1 As shown, the center of the outer cover plate 5 is fixedly connected to the handle 4, which is convenient for opening and closing the cover body.

[0035] In some embodiments, Figure 1 As shown, a sealing ring 6 is provided at the bottom of the outer cover plate 5 around the outer periphery of the plug plate 3 to improve the sealing performance of the cover body.

[0036] In some embodiments, Figure 1 As shown, the sealing ring 6 is an inflatable silicone sealing ring, and the sealing ring 6 has an inflatable cavity inside, and the inflatable cavity is connected to the inflating and deflation device, and the inflating and deflation device is installed on the outer cover plate 5. The sealing performance of the cover body can be further improved.

[0037] Furthermore, the air pressure of the inflatable silicone sealing ring 6 is adjustable, and the air pressure after inflation is 0.2-0.5 MPa.

[0038] In some embodiments, Figure 1 As shown, there are several ultraviolet lamps 7 evenly distributed on the side walls of the chamber, and the ultraviolet lamps 7 on each side wall are arranged in an array. The wavelength of the ultraviolet lamp 7 is 265nm, and the irradiation intensity is greater than or equal to 80μW / cm 2 . It can improve the sterilization effect.

[0039] In some embodiments, the copper ion loading of the copper-loaded zeolite adsorption layer 8 is greater than or equal to 3.5 wt %.

[0040] In some embodiments, the thickness of the lining antibacterial layer 11 is 2 mm, which can further improve the antibacterial and anti-chemical corrosion functions.
