Description

Technical Field

[0001] This utility model belongs to the field of waste incineration technology, and in particular relates to a sealing and adjusting device for the feed inlet of waste incineration power generation. Background Technology

[0002] Waste-to-energy incineration is a technology that incinerates municipal solid waste at high temperatures, converting the generated heat into electricity. It achieves three environmental goals: waste reduction, harmlessness, and resource recovery. Its core processes include pretreatment and incineration. Waste is fermented to increase its calorific value before being fed into the incinerator, where high temperatures thoroughly decompose pathogens and harmful substances. Energy conversion occurs when the incineration heat generates steam in a waste heat boiler, driving a steam turbine generator to produce electricity. Each ton of waste can generate 300-600 kWh of electricity. Pollution control is achieved through multi-stage purification of flue gas to ensure emissions meet national or EU standards. Leachate and slag undergo harmless treatment; the former is reused in production, while the latter can be used to make building materials. Waste-to-energy incineration can reduce waste volume by 90%, significantly saving land and replacing fossil fuels, making it highly significant for environmental protection.

[0003] Currently, the feed inlet of waste incinerators only has a simple opening and closing function. The feed hopper installed on the top of the feed inlet can only achieve two states: closed and open. At the same time, the connection between the feed hopper and the waste incinerator is not well sealed, which allows harmful gases to escape from the feed inlet during waste incineration. Therefore, it is necessary to provide a sealing adjustment device for the feed inlet of waste incineration power generation to solve the above problems. Utility Model Content

[0033] Preferably, the threaded sleeve 14 is fixedly installed on the back of the sealing plate 11. The top and bottom of the threaded sleeve 14 are flush with the top and bottom of the sealing plate 11. The sealing plate 11 is set in a movable groove opened at the lower end of the inner back of the feed hopper 2. The depth and height of the movable groove are the same as the width and height of the threaded sleeve 14, so that the threaded sleeve 14 cannot wobble in the mounting groove. The lead screw 15 is also located in the movable groove. One end of the lead screw 15 is rotatably connected to the inner wall of one side of the movable groove, and the other end of the lead screw 15 passes through a through hole opened on the right side of the feed hopper 2 and is connected to a second motor 16 fixedly installed at the bottom right side of the feed hopper 2.
