Cotton processing dust-removing machine set

Abstract

The invention relates to a cotton processing dust-removing machine set. A dust-removing chamber is arranged on an auxiliary support, and is divided into a first chamber and a second chamber; a second-stage dust-removing device is arranged between the first chamber and the second chamber; the second chamber is connected to the outside of the dust-removing chamber through a third-stage dust-removingdevice; the lower side of the second chamber is connected to a second impurity discharging device through a second impurity collecting hopper; an air inlet passage and a pressure relief valve are arranged on the side surface of the first chamber respectively; the lower side of the first chamber is connected to a first impurity discharging device through a first impurity collecting hopper; a first-stage dust-removing partition board is arranged on the side surface of the air inlet passage and on the inner side of the first chamber; a fan is arranged on the auxiliary machine set; the fan is connected with the second-stage dust-removing device through a first pipe; the fan is connected with the third-stage dust-removing device through a second pipe. The cotton processing dust-removing machine set has large processing capacity, achieves multi-stage filtration, has low resistance, low energy consumption, high dust-removing efficiency and a relatively small volume, reduces pollution, can treat high-concentration impurity dust and can automatically fall the dust.

Description

technical field [0001] The invention relates to the technical field of cotton processing equipment, in particular to a cotton with large processing capacity, multi-stage filtration, small resistance, low energy consumption, high dust removal efficiency, small relative volume, reduced pollution, capable of handling high-concentration dust, and automatic dust reduction Processing dust removal unit. Background technique [0002] As a large country in the textile industry, my country has a high cotton output; after cotton is planted and harvested, it needs to be ginned before it can be used as a semi-finished cotton product to flow to downstream processing enterprises. After the raw cotton is harvested, the seed cotton and lint contain a lot of impurities, such as cotton seeds, cotton shells, sand, sand, etc., so a lot of sand and dust will be generated during the ginning process, which will pollute the environment very much.

AI Technical Summary

Problems solved by technology

[0003] Now the corresponding research and development of dust removal equipment, but generally speaking, there are still the following problems: 1. Insufficient dust removal processing capacity; the dust processing capacity of dust removal equipment needs to be greatly improved to adapt to air purification with high dust concentration, such as: external cotton suction process, cashmere collection The process, especially the machine-picked cotton process, has a lot of dust; 2. The energy saving is poor, and the energy consumption of the processing equipment is large; the phenomenon of large horse-drawn carts is very common, especially the energy waste of the gas delivery system is very serious, and the actual wind speed is not calculated The wind speed is much higher, so it is difficult to accurately calculate the required air volume and the size of the pipeline, as long as there is no traffic jam; the resistance of Shacron 500-1000Pa is much higher than that of high-efficiency dust removal units, and the total pressure of the fan can be reduced, thereby reducing consumption; 3. Effective The fiber recovery rate is low; it is difficult to effectively separate the fibers by using Shacron and other equipment, or applying the similar principle of the Shacron, resulting in low recovery efficiency; Difficult, simply choose not to recycle, resulting in low cotton production rate and waste of resources; 4. Poor equipment reliability; because the dusty air is generated in a large amount, and the air volume and pressure are high, the equipment processing capacity and its own processing performance are required. If a more complex structural design is adopted in order to improve the dust removal efficiency, it will inevitably increase the number of monitoring equipment and reduce the reliability; and as a cotton processing industry with a huge daily processing capacity, once the equipment fails, it will inevitably bring huge economic losses to the enterprise. , so it is necessary to improve the reliability of the operation of the dust removal unit
