Paper mill fuel conveying device with screening function

Abstract

The invention discloses a paper mill fuel conveying device with the screening function. The paper mill fuel conveying device comprises a first conveying belt, a second conveying belt and a third conveying belt. Baffles are erected on the two sides of the first conveying belt to define the first conveying belt into a containing space with an opening in the upper portion. The first conveying belt is horizontally arranged, and one end of the first conveying belt serves as an output end. The second conveying belt inclines relative to the ground by 25 degrees to 35 degrees, the lower end of the second conveying belt is overlapped below the output end of the first conveying belt, and at least one rotary thumbing handle is erected above the middle portion of the second conveying belt to thumb raw materials on the second conveying belt to be flat. The third conveying belt inclines relative to the ground by 40 degree to 50 degrees, and the lower end of the third conveying belt is arranged below the higher end of the second conveying belt to receive falling materials. Conveying and screening can be integrated, the structure is simple, the screening effect is good, and time and labor are saved. The raw materials are firstly layered while the raw materials are conveyed, fuel with the larger size is separated out firstly, then impurities and fuel are separated, and the separation effect is improved.

Description

technical field [0001] The invention relates to the field of delivery devices. More specifically, the present invention relates to a paper mill fuel delivery device with a screening function. Background technique [0002] Traditional paper mills use coal as fuel to supply energy for production lines, but some paper mills also use plant residues such as bark, straw, and bagasse as fuel for production and energy supply. Using plant residues for production and energy supply has greatly improved the crop yield. The utilization rate and the avoidance of unreasonable disposal of crops to harm the environment have great benefits to the economy and the environment. [0003] However, there are many problems to be overcome in order to utilize crop residues. One of them is that during the process of collecting and chopping crop residues, some debris such as stones and iron will be mixed in. If the debris of the crops is directly put into the boiler for combustion, a lot of dregs will...

Problems solved by technology

[0006] However, this kind of conveying equipment can only separate the sundries that are quite different from the weight of the crops. Some sundries with small volume and weight equivalent to the remains of the crops are not isolated by these parabolic separation and inertial separation. Although these sundries are small in size , but the gravity is equivalent to the larger papermaking raw materials, so when parabolic separation and inertial separation are performed, this part of debris will still be mixed with the larger crop residues and cannot be separated
