Description

Technical Field

[0001] The utility model belongs to the technical field of volatile organic matter extraction, and in particular relates to a device for extracting volatile organic matter from solid waste. Background Art

[0002] Solid waste leaching toxicity usually refers to the harm caused by the migration and transformation of harmful substances leached from solid wastes when they come into contact with water, polluting the environment. In the newly promulgated "Identification of Leaching Toxicity of Hazardous Wastes Identification Standard" (GB5085.3-2007), the leaching toxicity index of volatile organic compounds has been added, among which 12 VOCs are hazardous components for leaching toxicity identification. If the content of any hazardous component in the solid waste leachate exceeds the concentration limit of the leaching toxicity identification standard specified in the "Identification of Leaching Toxicity of Hazardous Wastes Identification Standard (GB5058.3-2007)", the solid waste is judged to be a hazardous waste with leaching toxicity characteristics.

[0003] At present, the container and the top cover of the existing device for extracting volatile organic compounds from solid waste are mostly installed with bolts, and the bolts are embedded in the top cover through a shaft sleeve. Since the screw holes are directly opened on the top of the container, multiple bolts need to be screwed at the same time during the installation process, otherwise the top cover will be tilted, making it very inconvenient to open and close the top cover, and the thread groove is prone to damage. For this reason, we propose a device for extracting volatile organic compounds from solid waste. Utility Model Content

[0004] The purpose of the utility model is to provide a device for extracting volatile organic matter from solid wastes, so as to solve the existing problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for extracting volatile organic compounds from solid waste, comprising a container body, a top cover and a movable plate, wherein through holes are opened around the top of the container body, a top cover is provided on the top of the container body, bolts are screwed on the top of the top cover through threaded sleeves, and a movable connecting seat is provided around the outside of the top cover at positions corresponding to the bolts, a movable plate is provided on the outside of the movable connecting seat, and the movable plate is of an L-shaped structure. The movable plate is movably connected to the outer periphery of the top cover through the movable connecting seat, and a nut matched with the bolt is provided on one side of the bottom end of the movable plate, and the outer periphery of the nut is fixedly connected to the movable plate by welding.

[0006] Preferably, a knob is provided on the top of the bolt, and the knob is fixedly mounted on the top periphery of the bolt by means of a sleeve connection.

[0007] Preferably, a gas injection port is provided at the top of the top cover, and the gas injection port extends to the bottom of the top cover and is sealed and connected with the interior of the container body.

[0008] Preferably, a base is provided at the bottom of the container body, and the base is fixedly mounted on the bottom of the container body by welding.

[0009] Preferably, an exhaust port is provided on an outer side of the base, and the exhaust port is communicated with the interior of the container body.

[0010] Preferably, a negative pressure gauge is provided on an outer side of the base, and a sensing end of the negative pressure gauge extends to the interior of the container body.

[0011] Preferably, the outside of the exhaust port and the gas injection port are both equipped with a valve body, and the valve body is placed inside the exhaust port and the gas injection port and connected to an external lever.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The movable plate is installed around the outside of the top cover by using a movable connecting seat, and a nut is set on one side of the bottom end thereof, and the bolts that are spirally connected through the threaded sleeve on the top of the top cover are matched to achieve fixed installation of the top cover. In the process of disassembly and assembly, there is no need to screw too many bolts at the same time, which greatly reduces the difficulty of installing the top cover.

[0014] 2. By setting a reversible movable plate, the position of the nut can be reversed to avoid obstruction when installing the top cover. Such a design can also prevent the nut from being lost, thereby ensuring the normal installation and use of the top cover. BRIEF DESCRIPTION OF THE DRAWINGS
