Technical Field
The invention belongs to the recovery of long fibers of sterile seeds, is a recovery processing link of cotton processing leftovers, is used for purifying and recovering shorter fibers with textile value, and belongs to a cotton processing tail processing technology.
Background
The information in this background section is only for enhancement of understanding of the general background of the invention and is not necessarily to be construed as an admission or any form of suggestion that this information forms the prior art that is already known to a person of ordinary skill in the art.
In the process of cotton processing, seed cotton is subjected to cleaning, ginning and ginned cotton cleaning processes to generate a large amount of impurity leftovers, wherein the impurity leftovers contain a large amount of sterile seed cotton which is not fertilized and developed incompletely, long fibers with the textile value of less than 16mm grow on the surface of sterile seed kernels, and cotton processing enterprises generally install a sterile seed long fiber recovery process link in order to reduce the loss of cotton coats and leaves and increase the economic benefit.
At present, the existing sterile seed long fiber recovery process adopts a horizontal sterile seed long fiber purifying machine (a cleaning machine) as a production main machine, the main structure of the recovery process adopts a structure with one machine, two separators and two purifying rollers, two paths of material gas are separated and discharged, two paths of air suction are carried out, and two paths of impurities fall.
The schematic diagram of the currently used single machine process air network is shown in figure 1, and the recovery process flow is as follows: sterile seed leftover bits and pieces that are carried by cotton ginning workshop are responsible for 11 via defeated material, via the
Because the working host machine in the prior art is a horizontal sterile seed long fiber purification machine and has low handling capacity, most sterile seed long fiber purification production lines are provided with 4 and 6 host machines with different quantities, and materials are collected and a pipe network is arranged among all the devices in a branch pipe parallel connection mode. Because the wind power conveying systems of a plurality of devices share one fan, the number of branch pipes connected in parallel is large, the total length of the pipeline is long, the air leakage is large, and the pressure loss is large. Moreover, the air net occupies a large space and is disordered, the whole workshop layout is not attractive, the sight of a vehicle stop worker is shielded, and the safety production is not facilitated. The fan is installed at the far end of the process production line, so that almost all the air nets are in negative pressure operation.
Taking 4 production lines as an example, the process layout and the wind power transmission flow are shown in figure 2.
The problems that exist are that:
1) the fan and the working host machine are independently installed respectively in the workshop, the working host machine is installed in the workshop, the fan is installed in a special fan room outside the workshop, the distance between the fan and the special fan room is long, the pipe network is long, the pressure loss of the air network is large, air leakage is large, the required air quantity is large, therefore, the fan with a large model number needs to be selected for use to meet the use requirement, and the power consumption of the prior art is large.
2) The working main machine in the prior art, namely a horizontal sterile seed long fiber purification machine, adopts a structure of two separating devices, and air transmission pipelines coexist in series and parallel, so that the problems of complicated pipe network, more nodes, large local pressure loss at each node, large pressure loss of the air network and large air leakage are caused.
3) The fans used in the prior art mostly adopt 5-29 series common industrial fans, are limited by industrial characteristics, and cannot run efficiently, so that the air volume and the air pressure are not matched. The phenomenon that the trolley is pulled by a large horse is obvious, the power consumption is large, and in addition, the actual air volume is large, so that large operation pressure is caused for a subsequent dust removal system.
4) Because the wind power of the wind network in the prior art is relatively large, the performance of each equipment of a process system is influenced, and the equipment has high failure rate, large cotton loss and high personal accident rate.
