Fully-automatic waste recycling device of intelligent coal sampling machine

Abstract

The invention discloses a fully-automatic waste recycling device of an intelligent coal sampling machine. According to the fully-automatic waste recycling device disclosed by the invention, a rotary feeder is arranged underneath a discharge hole of a hopper; an accelerating chamber is arranged below the rotary feeder; a material transmission pipeline is arranged at one side of the rotary feeder; the material transmission pipeline is connected with a combined material-gas separator; the combined material-gas separator is connected with a gas conveying pipeline; the combined material-gas separator is connected with the gas conveying pipeline and a pipeline which communicates with a roots vacuum pump; the roots vacuum pump is connected with a programmed control system through a network; and the roots vacuum pump is electrically connected with an electrical control cabinet through an electric control unit. The hopper is arranged above the rotary feeder, a material level meter is arranged at one side of the hopper, and a waste collecting valve is arranged at the other side of the hopper. The material level meter is connected with an input end A1 of the programmed control system. The fully-automatic waste recycling device has the beneficial effects that: the whole device is stable in conveying, is suitable for medium-distance and long-distance conveying, is wide in scope of application, is low in energy consumption, is less in investment, is convenient to maintain, and is low in maintenance cost.

Description

technical field [0001] The invention relates to the field of mechanical devices for recovering fuel and energy waste materials in power plants, in particular to an automatic waste material recovery device for an intelligent coal prototyping machine. Background technique [0002] my country's electric power is based on coal-fired, mainly thermal power, and coal power accounts for 80% of the total power generation. A 1800MW thermal power plant burns more than 15,000 tons of standard coal a day and night (standard coal refers to low-level calorific value of 29307.6KJ / Kg of coal). Coal converts chemical energy into thermal energy through combustion, and thermal energy is converted into mechanical energy through boilers and steam turbines, and finally converted into electrical energy through generators. Therefore, thermal power plants are essentially energy conversion factories. At present, power fuels, especially coal quality, have been researched and developed from three aspe...

Problems solved by technology

At present, the production of coal samples is to send the coarsely broken coal samples (13mm particle size) to the sample preparation process, crush the coal to 6mm coal samples with a ring hammer crusher, shrink the coal samples, and put the coal samples into the oven Dry it, use a roller crusher to grind the coal sample into a coal sample below 2 mm, use a splitter to shrink the coal sample, and then pass it through a pulverizer and a sieve to sieve, and finally pour the coal sample under the sieve The coal sample bottle is put into the coal sample bottle, but there will be discarded samples in the process, and the recovery of discarded samples depends on manual regular cleaning, which is not only time-consuming and laborious, but also has low work efficiency, or the belt is used for short-distance straight-line recovery, that is, the conveyor belt is mainly used to carry objects , using the friction between each other to transfer objects from one position to another, not only has high requirements for the installation of the site, but also the cost of the conveyor belt equipment itself is high, neither of which can realize automatic recycling, resulting in automatic sample preparation and It is not "automatic" in the true sense, and at the same time, the safety of discarded samples cannot be effectively controlled
