Abstract
Description
Technical Field
[0001] This application relates to the field of cotton spinning technology, for example to a dust control device for organic cotton spinning. Background Technology
[0002] Currently, cotton spinning refers to the process of processing cotton fibers into cotton yarn and thread. During harvesting, transportation, and storage, cotton raw materials can become contaminated with various impurities, such as cotton leaves, cottonseed hulls, and sand. These impurities gradually detach and break down during the spinning process, forming dust. Short fibers in cotton are also easily airborne and generate dust during opening and carding processes. The dust generated during organic cotton spinning can negatively impact workers.
[0003] A related technology includes a dust removal device for spinning mills, comprising a filter box, a fan, and a filter screen. The filter box has an air inlet and an air outlet. The fan is located at the air outlet, and the filter screen is placed inside the filter box to filter the airflow. When the fan rotates, it draws airflow from the workshop into the filter box through the air inlet, filters the airflow through the filter screen, and then discharges the filtered airflow through the air outlet, thereby reducing and controlling dust and minimizing its impact on workers.
[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:
[0005] Filters are more likely to become clogged after prolonged use, which will affect their filtration efficiency.
[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content
[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.
[0008] This disclosure provides a dust control device for organic cotton spinning, which simultaneously cleans the filter element, reduces the risk of filter element clogging, improves the service life of the filter element, and ensures the filtration effect.
[0009] In some embodiments, the dust control device for organic cotton spinning includes: a housing, a fan, a filter element, and a dust collection bag. The housing has a filter chamber and a back-flushing chamber, and has a filter inlet and a filter outlet communicating with the filter chamber, as well as a back-flushing inlet and a back-flushing outlet communicating with the back-flushing chamber; one end of the fan is connected to the filter outlet, and the other end is connected to the back-flushing inlet; the filter element is rotatably disposed in the housing and has multiple filter zones; the dust collection bag is installed at the back-flushing outlet for collecting dust; wherein, part of the multiple filter zones is located in the filter chamber, and another part is located in the back-flushing chamber.
[0010] Optionally, the flow rate of the backflush chamber is less than or equal to the filtration capacity of the filter chamber.
[0011] Optionally, the backflushing outlet is connected to one end of the connecting pipe, the other end of the connecting pipe is connected to the dust collection bag, and the connecting pipe is fixedly connected to the housing.
[0012] Optionally, a spray element is rotatably provided inside the connecting pipe, and the spray element extends into the dust collection bag.
[0013] Optionally, the spraying component includes: a fixed pipe, a fixed box, a spray pipe, and spray heads. The fixed pipe passes through the connecting pipe; the fixed box is disposed inside the connecting pipe and communicates with the fixed pipe; the spray pipe is rotatably connected to the fixed box and communicates with the fixed box; multiple spray heads are provided and disposed on the spray pipe.

[0016] Optionally, an air inlet pipe is provided on the side wall of the enclosure, and a sealing plug is provided inside the air inlet pipe.
[0017] The dust control device for organic cotton spinning provided in this embodiment can achieve the following technical effects:
[0018] The fan starts, drawing air from outside the housing into the filter chamber through the filter inlet. The filter element filters the airflow, removing dust particles. The filtered airflow then flows through the filter outlet, the fan, and the back-flushing inlet into the back-flushing chamber. Inside the back-flushing chamber, the airflow is reversed, blowing dust off the filter surface and into the dust collection bag. This simultaneous cleaning of the filter element reduces the risk of clogging, extends its lifespan, and ensures effective filtration.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.
[0036] Combination Figures 1-2As shown in the figure, this embodiment of the present disclosure provides a dust control device for organic cotton spinning, comprising: a housing 100, a fan 200, a filter element 300, and a dust collection bag 400. The housing 100 is provided with a filter chamber 110 and a back-blowing chamber 120, and is provided with a filter inlet 111 and a filter outlet 112 communicating with the filter chamber 110, and a back-blowing inlet 121 and a back-blowing outlet 122 communicating with the back-blowing chamber 120; one end of the fan 200 is connected to the filter outlet 112, and the other end is connected to the back-blowing inlet 121; the filter element 300 is rotatably disposed in the housing 100 and is provided with multiple filter zones; the dust collection bag 400 is installed in the back-blowing outlet 122 for collecting dust; wherein, part of the multiple filter zones is located in the filter chamber 110, and the other part is located in the back-blowing chamber 120.
[0037] The dust control device for organic cotton spinning provided in this embodiment starts the fan 200, drawing air from outside the housing 100 into the filter chamber 110 of the housing 100 through the filter inlet 111. The filter element 300 filters the airflow in the filter chamber 110, thereby filtering out dust. The filtered airflow enters the back-blowing chamber 120 through the filter outlet 112, the fan 200, and the back-blowing inlet 121. The airflow in the back-blowing chamber 120 blows in the opposite direction towards the filter element 300, blowing away the dust on the filter surface of the filter element 300 and blowing the dust into the dust collection bag 400. This achieves simultaneous cleaning of the filter element 300, reducing the risk of clogging, increasing the service life of the filter element 300, and ensuring the filtration effect. The dust can be collected in the dust collection bag 400, making dust handling more convenient.
[0038] Understandably, the dust collection bag 400 is breathable; the filter element 300 performs filtration in part of the filtration area of the filter chamber 110, and the filter element 300 is in part of the filtration area of the back-blowing chamber 120, where it is cleaned by back-blowing.
[0039] Specifically, the backflushing outlet 122 and the filter inlet 111 are located at the top of the housing 100. This results in a relatively high filter inlet 111, leading to a relatively high adsorption height and a relatively large adsorption range. The relatively high height of the backflushing outlet 122 facilitates the replacement of the dust collection bag 400.
[0040] Optionally, multiple filter inlets 111 are provided, and filter inlets 111 are also provided on multiple outer side walls of the housing 100. In this way, the number of filter inlets 111 is relatively large, and the distribution area is relatively large, resulting in a relatively large adsorption range.
[0041] Combination Figure 3 As shown, optionally, the housing 100 is provided with a cover plate 113, which is used to cover the filter inlet 111. In this way, when the machine is turned off and not in use, the filter inlet 111 can be covered by the cover plate 113 for protection.
[0042] Optionally, a guide plate 130 is fixedly provided inside the housing 100, and the guide plate 130 is located on one side of the filter inlet 111. In this way, the airflow is guided towards the filter element 300 by the guide plate 130.
[0043] Optionally, the flow rate of the backflush chamber 120 is less than or equal to the filtration capacity of the filter chamber 110. In this case, when the flow rate of the backflush chamber 120 is less than the filtration capacity of the filter chamber 110, the air pressure inside the backflush chamber 120 is relatively high, which can better backflush away dust from the surface of the filter element 300, and the filtration area inside the filter chamber 110 is relatively large, resulting in a relatively good filtration effect. When the flow rate of the backflush chamber 120 is equal to the filtration capacity of the filter chamber 110, the airflow inside the backflush chamber 120 and the filter chamber 110 is more uniform.
[0044] Optionally, the flow rate of the filter chamber 110 is greater than or equal to the flow rate of the backflushing chamber 120, and less than or equal to four times the flow rate of the backflushing chamber. In this way, when the flow rate of the filter chamber 110 is less than the flow rate of the backflushing chamber 120, the air pressure in the backflushing chamber 120 is relatively low, and the backflushing effect is relatively poor.
[0045] Optionally, the filtration capacity of the filter chamber 110 is three times the flow rate of the backflushing chamber 120. In this way, the air pressure in the backflushing chamber 120 is relatively high, which can better blow away the dust on the surface of the filter element 300, and the filtration area in the filter chamber 110 is relatively large, resulting in a relatively good filtration effect.
[0046] Optionally, the backflushing outlet 122 is connected to one end of the connecting pipe 140, and the other end of the connecting pipe 140 is connected to the dust collection bag 400, and the connecting pipe 140 is fixedly connected to the housing 100. In this way, the length of the connecting pipe 140 is relatively long, and the risk of dust in the dust collection bag 400 flowing back into the housing 100 is relatively low.
[0047] Specifically, the connecting pipe 140 is a U-shaped pipe. This reduces the risk of dust in the dust collection bag 400 flowing back into the housing 100.
[0048] Optionally, the dust collection bag 400 is detachably connected to the connecting pipe 140. In this way, if there is a lot of dust in the dust collection bag 400, a new dust collection bag 400 can be installed, or the old dust collection bag 400 can be removed, cleaned, and then reinstalled.
[0049] Understandably, detachable connections can be secured by clamps or other common detachable structures.
[0050] Optionally, the connecting pipe 140 is fixedly connected to one end of the support rod 141, and the other end of the support rod 141 is fixedly connected to the outer wall of the housing 100. In this way, the stability of the connecting pipe 140 is increased by the support rod 141, reducing the risk of the connecting pipe 140 shaking.
[0051] Optionally, a spray element 500 is rotatably installed inside the connecting pipe 140, extending into the dust collection bag 400. In this way, when there is a large amount of dust in the dust collection bag 400 and it needs to be replaced, disassembling the dust collection bag 400 could easily cause dust to disperse. By installing the spray element 500, dust is sprayed into the dust collection bag 400 and the connecting pipe 140 in advance, reducing the risk of dust dispersion and minimizing the impact on operators.
[0052] Combination Figure 4 and Figure 5 As shown, optionally, the spray component 500 includes: a fixed pipe 510, a fixed box 520, a spray pipe 530, and spray heads 540. The fixed pipe 510 passes through the connecting pipe 140; the fixed box 520 is disposed inside the connecting pipe 140 and communicates with the fixed pipe 510; the spray pipe 530 is rotatably connected to and communicates with the fixed box 520; multiple spray heads 540 are provided and disposed on the spray pipe 530. In this way, water is injected into the fixed box 520 through the fixed pipe 510, and the water is then sprayed from the spray pipe 530 and the spray heads 540 into the dust collection bag 400 and the connecting pipe 140, reducing the risk of dust dispersion and minimizing the impact on operators. Furthermore, the spray pipe 530 can rotate relative to the fixed box 520, allowing the spray heads 540 to rotate while spraying, resulting in more uniform spraying and better effect.
[0053] Optionally, a first motor 550 is provided on the fixing box 520, and the output end of the first motor 550 passes through the fixing box 520 and is connected to the spray pipe 530. In this way, the first motor 550 provides power for the spray pipe 530 to rotate relative to the fixing box 520.
[0054] Combination Figure 6 and Figure 7 As shown, optionally, a sealing plate 150 is provided on the outer side of the filter element 300. The sealing plate 150 is fixedly connected to the inner side wall of the housing 100, and the filter element 300 is rotatably disposed on the inner side of the sealing plate 150. In this way, by cooperating with the sealing plate 150 and the filter element 300, the risk of dust on the filter surface of the filter element 300 reaching the opposite side of the filter element 300 is reduced.
[0055] Specifically, a partition plate 160 is fixedly installed inside the housing 100, which divides the space inside the housing 100 into a filter chamber 110 and a backflushing chamber 120.
[0056] Specifically, the partition 160 has an L-shaped plate structure.
[0057] Optionally, a connecting frame 170 is fixedly installed inside the housing 100, and the connecting frame 170 is rotatably connected to the filter element 300. In this way, the filter element 300 and the connecting frame 170 are rotatably connected, and the connection stability is relatively high.
[0058] Specifically, the connecting bracket 170 is L-shaped. In this way, the shape of the connecting bracket 170 corresponds to the shape of the partition plate 160.
[0059] Optionally, two partition plates 160 are provided, located on both sides of the filter element 300; two connecting brackets 170 are provided, located on both sides of the filter element 300, with the two partition plates 160 abutting against the two connecting brackets 170 respectively. In this way, the abutting between the partition plates 160 and the connecting brackets 170 provides a relatively good sealing effect, reducing the risk of air mixing between the filter chamber 110 and the backflush chamber 120.
[0060] Specifically, filter element 300 has a circular plate-like structure.
[0061] Optionally, the connecting frame 170 is located between the partition plate 160 and the filter element 300, and the filter element 300 has four sealing strips 310 on its side, with the included angle between adjacent sealing strips 310 being a right angle, and two of the sealing strips 310 being located between the filter element 300 and the connecting frame 170 and abutting against the connecting frame 170. In this way, the partition plate 160 and the connecting frame 170 abut against each other, and the sealing strips 310 abut against the connecting frame 170, resulting in a relatively good sealing effect and reducing the risk of air mixing between the filter chamber 110 and the backflush chamber 120.
[0062] Understandably, the four sealing strips 310 divide the filter element 300 into four filtration zones, one of which is located in the backflushing chamber 120, and the other three are located in the filtration chamber 110. After the filter element 300 in the backflushing chamber 120 has finished backflushing, the filter element 300 rotates to backflush the next filtration zone.
[0063] Optionally, the connecting frame 170 is equipped with a gearbox 171, and the gearbox 171 is equipped with a second motor 172. The output end of the second motor 172 is connected to the filter element 300 through the gearbox 171. In this way, the second motor 172 provides power for the rotation of the filter element 300 through the gearbox 171.
[0064] Specifically, the filter element 300 has a filter element 300 shaft in the middle, the filter element 300 shaft is rotatably connected to the connecting frame 170, and the filter element 300 shaft is connected to the output end of the second motor 172 through the gearbox 171.
[0065] Optionally, an air inlet pipe 180 is provided on the side wall of the housing 100, and a sealing plug 181 is provided inside the air inlet pipe 180. In this way, the adsorption range and area can be increased through the air inlet pipe 180, and the adsorption effect can be increased by extending the pipe and setting it in the cotton spinning processing area.
[0066] Optionally, multiple air inlet ducts 180 are provided. This allows for the connection of multiple extension ducts.
