Solid waste one-way self-closing feeding device

Abstract

The invention discloses a solid waste one-way self-closing feeding device which comprises a feeding barrel assembly, a one-way self-closing and opening device, a lateral positioning linkage device anda power fixed-axis rotating assembly. The feeding barrel assembly is provided with an outer barrel body, an inner barrel body, an outer side reinforcing bar board and a positioning bearing pedestal.The outer side reinforcing bar board is fixed to the outer side of the outer barrel body. The positioning bearing pedestal is installed on a left protruding saddle at the bottom of the outer side reinforcing bar board. A boss region is arranged at the inner side of the inner barrel body. The one-way self-closing and opening device is installed at the boss region. The one-way self-closing and opening device is provided with a tongue-shaped one-way door. The tongue-shaped one-way door is installed at the boss region and can be opened or closed along a boss region installing portion. The power fixed-axis rotating assembly is provided with a transmission shaft. One end of the transmission shaft is installed on the positioning bearing pedestal, and the other end of the transmission shaft is connected with the lateral positioning linkage device. It is ensured that solid waste enters a high-temperature incineration furnace from one direction, and the solid waste can be sufficiently preheatedbefore complete incineration.

Description

technical field [0001] The invention relates to the field of high-temperature kiln components for recycling solid waste, and specifically belongs to a one-way self-closing feeding device for solid waste. [0002] technical background [0003] In recent years, as governments at all levels have higher and higher requirements for environmental protection. The treatment of solid waste has changed from the usual landfill treatment to high-temperature incineration for resource utilization. Now the country strongly recommends adding appropriate raw and auxiliary materials to solid waste, some hazardous waste, stale solid-liquid mixed waste, and solid waste from industrial enterprises through high-temperature incineration to make new environmentally friendly building materials. When incinerating solid waste into new environmentally friendly building materials and realizing resource utilization, it is necessary to add solid waste into the high-temperature kiln for resource utilizatio...

Problems solved by technology

[0004] However, the feeding device at the feed inlet of a common high-temperature kiln has the following problems in actual use: 1) the design of the opening and closing blanking door of some feeding devices is unreasonable, and this opening and closing blanking door is usually bidirectional. Opening and closing, in the actual blanking process, when the high-temperature dust in the high-temperature kiln enters the kiln, due to the large temperature difference between the inside and the outside, it often happens that the high-temperature material in the kiln rushes out of the material inlet in reverse, which seriously affects normal production and use. ;2) When the solid waste enters the kiln, the feeding device at the inlet of the ordinary high-temperature kiln opens the inlet door, and the high-temperature heat in the kiln rushes out of the inlet in reverse, and a large amount of heat will be taken away at this time. The temperature fluctuation range of the high-temperature kiln is relatively large, which will cause a lot of energy to be wasted, and will also seriously affect the overall performance of the production of new environmentally friendly building materials; There are only two situations of fully open and fully closed. There is no buffer opening and closing degree, and it is impossible to preheat part of the solid waste entering the kiln, which makes the heat utilization rate of the high incineration kiln low.
