preparation example Construction

[0040] In the present invention, the preparation process of shaped straw and the shaped straw powder preparation process may not be in the same area, but may be separated by several kilometers, or they may be in the same area. The shaped straw storage can be set in the area where the shaped straw is prepared, or in the area where the shaped straw powder is prepared, or can be set in both areas, or neither can be set.

[0041] Various machines involved in the processing equipment of the present invention can adopt the prior art, and other powder metering and conveying equipment are equally applicable to the present invention. In the present invention, the connection between the formed straw powder burner and the decomposition furnace is not limited to one.

[0042] The process principle of the processing technology of the molded straw powder of the present invention is: when the straw is compressed and molded, due to the temperature above 70°C, the structure of the straw change...

Embodiment 1

[0045] The processing equipment for forming straw powder in this embodiment includes a straw measuring ground balance 12, a straw collecting hopper 14, a straw feeder 15, a first belt conveyor 16, a straw crusher 17, a second belt conveyor 18, and a straw forming machine. 19. The third belt conveyor 20, the formed straw unloading pit 24, the quantitative feeder 25, the fifth belt conveyor 26, the formed straw pulverizer 27, the bag dust collector 28, the exhaust fan 29, the formed straw powder screw conveyor 30 and forming straw powder storage bin 31; above-mentioned straw metering ground balance 12, straw collecting hopper 14, straw feeder 15, first belt conveyor 16, straw crusher 17, second belt conveyor 18, straw molding machine 19 and the third belt conveyor 20 are connected in turn according to the process conditions, and the materials in the third belt conveyor 20 are directly poured into the first forming straw storage warehouse 21 or transported to the second forming st...

Embodiment 2

[0051]The connection relation of the processing equipment of the molding straw powder of this embodiment and the step of process are the same as that of Embodiment 1, the difference is that the first molding straw storage house 21 is not set for the straw of this embodiment, and the molding straw is directly delivered by the transportation means (truck 13) Enter the second molding straw storage warehouse 22 or molding straw unloading pit 24. This embodiment is applicable to the situation that the molded straw storage can be arranged on the site of the cement factory.

Abstract

The invention relates to a processing device and process of formed straw powder and application. A straw metering platform scale, a straw collecting hopper, a straw feeding machine, a first rubber belt conveyor, a straw crusher, a second rubber belt conveyor, a straw forming machine and a third rubber belt conveyor are sequentially connected according to process conditions. Materials in the third rubber belt conveyor are directly poured into a first forming straw storage depot or are conveyed to a second forming straw storage depot or a forming straw unloading pit through a conveying tool. The materials in the first forming straw storage depot are also conveyed to the second forming straw storage depot or the forming straw unloading pit. The second forming storage depot and the forming straw unloading pit are connected through a fourth rubber belt conveyor. A ration feeding machine is connected to the position below the forming straw unloading pit. An outlet of the ration feeding machine is sequentially connected with a fifth rubber belt conveyor, a forming straw pulverizer and a bag dust filter. An outlet of the bag dust filter is connected with an exhaust fan through a pipeline, and a forming straw powder spiral conveyer is connected to the position below the bag dust filter.

Description

technical field [0001] The invention belongs to the technical field of cement production in agriculture and building materials industry, and in particular relates to processing equipment and technology for forming straw powder. Background technique [0002] Biomass energy is an important renewable energy source and one of the important energy sources for human survival. It ranks fourth in the world's total energy consumption after coal, oil, and natural gas. Its development and utilization can Supplementing the shortage of conventional energy sources also has significant environmental benefits. Therefore, the development and utilization of biomass energy has become a worldwide research topic. [0003] Biomass energy resources mainly come from the fields of agriculture, forestry, and animal husbandry, mainly including crop straw, forest by-products, and livestock manure. my country is very rich in biomass resources. The annual output of crop straw alone is more than 700 mil...
