Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to a reliable new dust removal device for textiles. Background Technology

[0002] In the textile production process, processes such as carding, spinning, and weaving generate a large amount of fiber dust and impurities. This dust not only pollutes the production environment but may also harm the health of operators. Furthermore, dust adhering to the surfaces of textile equipment components or within the yarn can affect the stability of equipment operation and the quality of textiles. Therefore, dust removal devices have become an indispensable key piece of equipment in textile workshops. Among them, baghouse dust collectors are widely used in dust purification in the textile industry due to their advantages such as high filtration efficiency, simple structure, and wide applicability.

[0003] The core working principle of existing baghouse dust collectors is to filter dust-laden airflow through filter bags, trapping dust on the outer surface of the filter bags to achieve gas-solid separation. As the filtration process continues, dust gradually accumulates on the filter bag surface, forming a dust layer. This increases filtration resistance and affects dust collection efficiency, necessitating the use of a pulse-jet dust collector for cleaning. The cleaning method of a pulse-jet dust collector typically involves releasing a high-pressure airflow instantaneously through a pulse valve, creating a pulse jet that impacts the filter bag, causing it to vibrate violently and thus removing the dust adhering to its surface.

[0004] However, existing pulse jet cleaning methods have significant technical drawbacks: during the cleaning process, a large amount of dust dislodged by the pulse jet floats in the airflow around the filter bags. Since textile production typically requires continuous operation, the dust collection system must remain running. Before the floating dust can settle or be collected, it is re-adsorbed by the filter bags. This phenomenon prevents dust from effectively detaching from the dust collection system, significantly reducing the actual cleaning efficiency, increasing the operating frequency of the pulse jet dust collector, accelerating filter bag wear, shortening filter bag lifespan, and affecting the overall dust collection efficiency and operational stability of the system. Consequently, it fails to meet the textile industry's actual needs for efficient and reliable dust collection. Utility Model Content

[0011] A removable and cleanable filter assembly is installed between the baffle and the bottom of the dust removal chamber.

[0012] Furthermore, it also includes two third gas collecting pipes, both of which are installed on the side wall of the equipment body. The positions of the two third gas collecting pipes are adapted to the left and right chambers of the baffle. The output end of each third gas collecting pipe is connected to several evenly distributed pipes.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] The design adopts "alternating dust removal + directional airflow guidance". During dust removal, the valves of the corresponding output pipe and input pipe are closed and the valve of the third air collection pipe is opened. The airflow is delivered downward through the uniform distribution pipe, carrying the shaken dust and precisely guiding it to the filter screen. This completely avoids the floating dust being adsorbed by the filter side bag again, and the dust removal efficiency is significantly improved.

[0021] The dust filter is designed to intercept dust only during the dust removal stage, avoiding ineffective losses during normal filtration. At the same time, it accurately captures suspended dust generated during dust removal, further improving the overall dust removal accuracy and dust collection rate.

[0022] The two chambers can switch operation independently, and the other side maintains normal filtration during the dust removal process without stopping the machine. This is fully adapted to the continuous production needs of textile workshops and ensures that production efficiency is not affected.

[0023] The uniform distribution pipe and the third gas collecting pipe work together to form a directional downward airflow, which accelerates the movement of the shaken dust towards the filter screen, shortens the dust residence time in the chamber, reduces the secondary wear of dust on the bag assembly, and extends the service life of the bag.

[0024] The filter assembly adopts a detachable sliding structure, combined with a sealing and limiting design, which not only ensures airflow sealing during dust removal, but also facilitates filter cleaning and maintenance, reducing equipment operation and maintenance costs.

[0025] The electrically controlled valve enables rapid switching between the dust removal side and the filtration side, making operation convenient and improving the degree of automation, thereby enhancing the stability and intelligence of the equipment operation. Attached Figure Description

[0099] The working principle of this utility model is as follows:

[0100] The core of this novel dust removal device for textiles adopts a "synchronous filtration + alternating dust removal" working mode, which is specifically divided into two stages:

[0101] 1. Normal Filtration Stage: All valves 14 on the output pipes 12 and 14 on the input pipes 8 are open, while valve 14 on the third collecting pipe 15 is closed. The dust-laden airflow generated during textile production is diverted through the air supply pipe and the first collecting pipe 9 to the input pipes on both sides of the baffle 6, entering the dust removal chambers on both sides of the baffle 6. Under the pressure difference generated by the fan, the dust-laden airflow flows upward. After being filtered by the bag assembly 3, the dust is trapped on the surface of the bag, and the purified gas enters the upper chamber of the partition 2 through the bag assembly 3, and then exits through the output pipe 12, the second collecting pipe 13, and the exhaust pipe. At this time, the filter assembly below the baffle 6 does not play a major role, and both chambers simultaneously achieve efficient filtration.

[0102] 2. Alternating Dust Removal Stage: When one side of the bag assembly 3 needs dust removal, close the valve 14 of the output pipe 12 and the valve 14 of the input pipe 8 on that side, open the valve 14 of the corresponding third air collection pipe 15, and start the pulse dust removal mechanism 4. The pulse dust removal mechanism 4 releases high-pressure pulse airflow to the bag assembly 3 on that side through the pulse pipe and nozzle 5, shaking off the dust adhering to the surface of the bag. At the same time, part of the dust-laden airflow is diverted to the distribution pipe 16 through the third air collection pipe 15, and a directional airflow is sprayed downward through the air outlet 17 at the bottom of the distribution pipe 16, carrying the shaken-off suspended dust downwards towards the baffle 6. When the dust passes through the filter assembly under the guidance of the airflow, it is intercepted by the dust filter screen 21 and settles into the corresponding side ash hopper 10, and finally discharged by the screw conveyor mechanism 11. During this process, the other chamber maintains normal filtration and does not need to be stopped. After the dust removal on this side is completed, switch the state of valve 14 to restore its filtration function, and then perform the above dust removal process on the other side of the bag assembly 3 to achieve cyclical alternating dust removal, which ensures the dust removal effect without affecting the continuity of textile production.

[0103] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
