Description

Technical Field

[0001] This utility model relates to lint collection and treatment technology, specifically a lint collection device for carpet processing. Background Technology

[0002] During the manufacturing process, whether machine-woven, tufted, or hand-knotted, carpet surfaces will have short pile, loose fibers, or fiber debris left over from cutting. These loose fibers will shed in large quantities during initial use and remain in the air. These airborne fibers can then enter a patient's nasal cavity or lungs through the respiratory tract.

[0003] To address this issue, air purification systems are typically added to factories. For example, Chinese Patent CN117779435A, published on March 29, 2024, discloses an air lint removal device for textile workshops. This device utilizes a flattening self-cleaning lint removal mechanism to flatten the fabric with lint adhering to it, exposing the lint hidden in folds and rolled edges. Then, it removes the lint from the fabric surface through a sweeping and adsorption process, preventing lint from remaining hidden in folds and rolled edges. It can also scrape lint adhering to the upper part of the filter screen, concentrating the lint in one location for easier collection and preventing filter clogging.

[0004] In existing technologies, including the aforementioned patents, so-called air purification essentially involves drawing airflow into a filter and then expelling the filtered air. Fibers, however, are different from dust in the air. Fibers cannot penetrate the interior of the filter media; they only adhere to the outer wall. This causes a thick layer of fiber to accumulate on the outside of the filter media very quickly, affecting airflow and reducing or ultimately eliminating its filtration effectiveness. While this problem can be solved by scheduling regular cleaning, the cleaning intervals are extremely short due to production constraints. Utility Model Content

[0005] The purpose of this invention is to provide a lint collection device for carpet processing to address the aforementioned shortcomings of the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lint collection device for carpet processing, comprising a filter inner cover, wherein a winding rod is centrally threadedly connected to the filter inner cover.

[0007] The top of the inner side of the filter element inner cover is fixedly connected to an air inlet pipe distributed in a circumferential array around the attached rod, and the air inlet pipe includes a funnel-shaped air outlet pipe.

[0008] An arc-shaped guide plate is fixedly installed on the top of the inner side of the filter element inner cover, and one end of the arc-shaped guide plate is fixedly connected to one end of the air inlet on the air inlet pipe.

[0009] The attached rod is located on the parabola of the arc-shaped guide plate.

[0010] Preferably, the filter inner cover is divided into an upper part and a lower part according to its structure, and the two are fixedly connected by a joint. The circumferential radius of the upper part is larger than that of the lower part, and a number of air holes are opened on the joint.

[0011] The cross-section of the funnel-shaped air outlet pipe is on the same horizontal plane as the junction of the lower part and the joint.

[0012] Preferably, the attached rod is provided with a number of round rods.

[0013] Preferably, the end of the attachment rod is fixedly installed with an air guide basin embedded in the bottom opening of the filter element inner cover;

[0014] The funnel-shaped air outlet duct is located inside the air guide basin, and the extension line of its outer wall is tangent to the extension line of the inner wall of the air guide basin port.

[0015] Preferably, the port of the air guide basin is a constricted opening, and the center point of the axis around the attached rod is located on the extension line of the inner wall of the constricted opening.

[0016] Preferably, a flange is threaded into the opening and abuts against the bottom of the air guide basin;

[0017] It also includes a housing, the filter element inner cover is inserted into the port of the housing, and a plurality of threaded rods fixedly disposed at the bottom of the flange extend out from the perforations opened on the housing.

[0018] Preferably, the top of the filter element inner cover is fixedly installed with a mounting flange, which covers the port of the outer shell and is fixed by bolts.

[0019] Preferably, an air cavity is formed between the inner cover of the filter element and the outer shell, and the air cavity is connected to an air outlet flange pipe that is fixedly connected to the side wall of the outer shell.

[0020] Preferably, the system also includes a gas collection hood that is fixedly installed on the top of the inner cover of the filter element. The gas collection hood is in the shape of a bowl, and the inner ring of its port is tangent to the air inlet pipe.

[0021] Preferably, the inner cover of the filter element is made of high-toughness polyethylene plastic.

[0022] In the above technical solution, the lint collection device for carpet processing provided by this utility model has the following beneficial effects: Air from the factory enters through the inlet duct and flows towards the inner cover of the filter element. A funnel-shaped outlet duct is added to the outlet of the inlet duct, thus reducing the cross-section of the outlet. This prevents the airflow from passing quickly through the funnel-shaped outlet duct, causing it to accumulate inside the inlet duct. The airflow then flows towards the attachment rod through the air outlet guided by the arc-shaped guide plate. The multiple arc-shaped guide plates guide the airflow, creating a vortex centered on the attachment rod inside the inner cover of the filter element. This causes the fibers in the airflow to adhere to the attachment rod, thereby achieving fiber collection. By adding a filter to the existing filtration system, fibers are pre-collected, reducing the fiber content in the airflow to the filter material to a minimum or zero. This allows the filter element to effectively filter dust from the air without becoming unusable due to fiber accumulation clogging the outer perimeter.

[0023] Secondly, by increasing pre-collection, the manual cleaning cycle of the entire filtration system can be extended. Attached Figure Description

Detailed Implementation

[0033] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0034] Please see Figure 1-6 This utility model provides a technical solution, including the following embodiments:

[0035] Example 1

[0036] Combination Figure 1 , Figure 2 and Figure 3 This embodiment adds a pre-filtration step, namely a lint collection device, to the original filtration system. This device pre-collects fibers in the air before they enter the main filter material by adding a lint collection device to the filtration pipeline leading to the main filter material. This allows the main filter element to focus on filtering dust in the air and avoids failure due to fiber accumulation clogging its periphery.

[0037] Specifically, the lint collection device includes an inner filter element housing 1 and an outer casing 8. The inner filter element housing 1 is centrally installed inside the outer casing 8, forming an annular air chamber 100 between the inner filter element housing 1 and the outer casing 8. The top of the inner filter element housing 1 extends to the outside of the port of the outer casing 8. A mounting flange 6 is fixed to the top of the inner filter element housing 1 and covers the port of the outer casing 8, and the two are fixedly connected by bolts.

[0038] The outer casing 8 is provided with an air outlet flange pipe 81 that communicates with the air chamber 100, which is used to connect to the downstream pipe of the original filtration system and output the airflow after pre-collection and fiber removal.

[0039] An air collection hood 9 is fixedly installed on the top of the filter inner cover 1. The air collection hood 9 is bowl-shaped and is used to connect to the upstream pipe of the original filtration system to receive air containing fibers.

[0040] Example 2

[0041] Combination Figure 4As shown, this embodiment details the structure of the filter inner cover 1. A spiral rod 2 is threadedly connected to the center of the filter inner cover 1. Multiple air inlet pipes 3 are fixedly connected to the top inner side of the filter inner cover 1, and these air inlet pipes 3 are arranged in a circular array around the spiral rod 2. Each air inlet pipe 3 has a funnel-shaped air outlet pipe 31 at its outlet end. An arc-shaped guide plate 32 is also fixedly installed on the top inner side of the filter inner cover 1, with one end of the arc-shaped guide plate 32 connected to a specific air vent on the air inlet pipe 3 (or, as can be understood, a position adjacent to the outlet of the funnel-shaped air outlet pipe 31). The axis of the spiral rod 2 is designed near the focus or a suitable position of the parabola formed by the arc-shaped guide plate 32 to ensure a guiding effect.

[0042] Furthermore, an inner tube 4 is fixedly installed inside the air inlet duct 3. The inner tube 4 is connected to the top of the filter inner cover 1, but its wall maintains a certain predetermined distance from the inner wall of the air inlet duct 3. The length of the inner tube 4 is greater than the arch height of the arc-shaped guide plate 32 (the original "thickness" refers to the vertical distance from the apex of the arc-shaped guide plate 32 to the point where it connects to the inner wall of the filter inner cover 1).

[0043] A number of round rods 21 are arranged around the attached rod 2 (combined with) Figure 5 As shown in the figure, it is used to increase the attachment points and fixation effect of fiber winding.

[0044] During operation, fiber-containing factory air enters through the air collection hood 9 (the specific guidance to the air inlet duct 3 needs to be referred to the attached diagram or supplementary explanation), and flows into the inner cover 1 of the filter element through the air inlet duct 3. The funnel-shaped air outlet duct 31 at the outlet end of the air inlet duct 3 reduces the outlet cross-sectional area, causing the airflow to accumulate to a certain extent within the air inlet duct 3. The accumulated airflow overflows from the air outlet of the air inlet duct 3 (or immediately adjacent to the funnel opening), and under the guidance of the arc-shaped guide plate 32, changes its flow direction and flows around the attached rod 2. The combined guiding effect of multiple arc-shaped guide plates 32 creates a vortex airflow inside the inner cover 1 of the filter element, with the attached rod 2 as the central axis. Under the action of centrifugal force, the fibers in the airflow are thrown towards and wrapped around the attached rod 2 and its round rod 21, achieving pre-collection of fibers. After this pre-collection process, the fiber content in the airflow is significantly reduced or even reduced to zero. The treated airflow will enter the subsequent process, and finally flow through the air chamber 100 and the air outlet flange pipe 81 to the main filter element of the original filtration system, so that it can effectively filter dust and avoid fiber clogging.

[0045] Example 3

[0046] Combination Figure 4 As shown, this embodiment is an optimization based on the filter inner cover 1 provided in Embodiment 2. The filter inner cover 1 is structurally divided into an upper part 11 and a lower part 12, which are fixedly connected by a joint 13. The circumferential radius of the upper part 11 is larger than that of the lower part 12. A number of air holes 131 are provided on the joint 13.

[0047] The plane at the outlet end (minimum cross-section) of the funnel-shaped air outlet duct 31 is at the same horizontal level as the top of the lower part 12 (i.e. the connection surface with the joint 13).

[0048] During operation, as described in Embodiment 2, the airflow forms a vortex under the guidance of the arc-shaped guide plate 32, and the fibers are collected around the attachment rod 2. The cleaner airflow after fiber separation, under the action of the vortex, mainly flows out of the filter inner cover 1 through the air hole 131 on the joint 13 and enters the air cavity 100 between the filter inner cover 1 and the outer shell 8. The airflow then gathers through the air cavity 100 and is output through the outlet flange pipe 81.

[0049] Example 4

[0050] Based on Embodiment 3, this embodiment further optimizes the fiber locking effect. An air guide basin 33 is integrally formed at the bottom end of the attached rod 2. The air guide basin 33 is embedded in the bottom opening of the lower part 12 of the filter inner cover 1. The outlet of the funnel-shaped air outlet pipe 31 extends into the interior of the air guide basin 33, and the extension line of its outer wall is approximately tangent to the extension line of the inner wall of the port of the air guide basin 33.

[0051] The port of the air guide basin 33 is an upwardly constricting constriction portion 331. The center point of the axis around the attachment rod 2 is located within the extended region of the conical surface formed by the inner wall of the constriction portion 331.

[0052] The air guide basin 33 is fixed by a flange 7. The flange 7 is threaded into the bottom opening of the lower part 12 of the filter element inner cover 1, and its disc surface is pressed against the flange structure (or flange) at the bottom of the air guide basin 33. Multiple threaded rods 71 ​​are fixedly provided at the bottom of the flange 7. These threaded rods 71 ​​extend through corresponding perforations at the bottom of the outer shell 8, which facilitates the installation and fixation of the entire lint collection device with external supports or pipes.

[0053] During vortex formation, some of the downward-flowing airflow or the airflow at the bottom of the vortex impacts the bottom of the air guide basin 33. Constrained and guided by the inner wall of the air guide basin 33 (especially the constriction portion 331), this portion of the airflow swirls upward along the inner wall. This swirling airflow forms a local wind screen or air curtain near the constriction portion 331. This wind screen helps to "lock" the fibers already wrapped around the attachment rod 2 in the attachment rod area, preventing them from being carried away or re-lifted by any possible downward or turbulent airflow, thereby enhancing the stability and effectiveness of fiber collection.

[0054] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
