Description

Technical Field

[0001] This utility model relates to a fiber washing equipment, and more particularly to a washing module and a hollow fiber washing and drying equipment. Background Technology

[0002] Hollow fiber is a type of chemical fiber characterized by its axially arranged tubular cavity structure. Its main materials include polyester, PTT (polypropylene terephthalate), and other high-molecular polymers. This material forms cavities through special processes (such as slot spinnerets or weaving techniques), giving products lightweight, warm, breathable, and highly efficient separation properties, making it widely used in textiles, medical devices, water treatment, and other fields.

[0003] Hollow fiber typically requires washing and drying processes during production. Like conventional fibers, hollow fibers are prone to clumping during the washing stage, causing large particles of impurities to become trapped inside the fibrous material and difficult to remove. Existing cleaning equipment has introduced agitation mechanisms to address this issue, using mechanical stirring to enhance the cleaning effect. However, this significantly increases the degree of fiber breakage. Summary of the Invention

[0004] This invention provides a cleaning module and a hollow fiber washing and drying equipment, which solves the problem in the prior art that fibers easily clump together during the washing process, making it difficult to remove large particles of impurities.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a cleaning module, comprising:

[0006] The base is formed by sealing the upper cover and the bottom plate together. A water injection cavity is defined between the upper cover and the bottom plate. A water injection pipe communicating with the water injection cavity is provided on the base. A number of evenly distributed water outlet holes are provided on the upper cover.

[0007] The foaming unit is located inside the water outlet and consists of an air injection core and a refining sheet. The air injection core is a hollow tubular structure with a hollow disc at its upper end. Several water-blocking protrusions are arranged in a circular array on the bottom surface of the disc. The outer side wall of the water-blocking protrusions is provided with an exhaust port that runs through the inside and outside. The refining sheet covers the upper side of the air injection core.

[0008] The air injection tube assembly consists of a main air tube and branch air tubes connected together. The main air tube passes through the base and extends into the water injection chamber, and the branch air tubes are connected to the bottom of all the air injection cores.

[0009] In this invention, the main air pipe is connected to the air pump, which continuously supplies air to the air injection core in the foaming unit, while the water injection pipe is connected to the water supply line for continuous water supply. When water enters the outlet hole at a high pressure, the water flow velocity increases sharply due to the small hole diameter. After the high-speed water flow impacts the bottom surface of the disc, the water flow diffuses outward and is dispersed into multiple streams under the action of the water-blocking protrusion. The space for water flow begins to increase sharply, the water pressure decreases, and at the same time, a large amount of gas is sent out from the exhaust port. This gas mixes into the water and passes through the refining plate at high speed, completely refining the bubbles. A large number of bubbles are ejected from the foaming unit with the water flow.

[0010] This utility model also provides a hollow fiber washing and drying device, including a washing and drying box. The washing module is provided at the bottom of the inner cavity of the washing and drying box, and an overflow pipe is provided on the upper side of the inner cavity of the washing and drying box. A filter is provided at the inner opening of the overflow pipe. The washing and drying box in this hollow fiber washing and drying device is a conventional structure. By introducing the washing module and the overflow pipe, the hollow fibers can be subjected to a water flow impact effect in the washing mode. The high-speed water flow ejected from the washing module is mixed with a large number of fine bubbles, which can impact the clumped fibers. The continuously rising large number of bubbles also continuously provide a disturbance effect to the fibers in the water, which can not only prevent the fibers from clumping, but also carry away the light impurities adsorbed on the fibers. The light impurities will be discharged from the overflow pipe with the water flow.

[0011] Therefore, this utility model has the following characteristics compared with the prior art: 1. By impacting the clumped fibers with high-speed water flow, the fibers can be fully and continuously agitated, improving the cleaning effect and also playing a certain role in preventing clumping; 2. A large number of air bubbles in the water flow will mix into the fibers, playing a role in preventing clumping and also carrying away light impurities adsorbed on the fibers.

[0017] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0019] Example 1: See Figure 1 and Figure 2 A cleaning module, comprising:

[0020] The base 100 is formed by sealing the upper cover 110 and the bottom plate 120 together. The upper cover and the bottom plate define the water injection cavity 130. The base is provided with a water injection pipe 140 that communicates with the water injection cavity. The upper cover is provided with several evenly distributed water outlet holes 150. The spacing between adjacent water outlet holes is controlled between 15 and 20 cm.

[0021] See Figure 3 The foaming unit 200 is located inside the water outlet and consists of an air injection core 210 and a refining sheet 220. The air injection core is a hollow tubular structure with a hollow disc 230 at its upper end. Several water-blocking protrusions 240 are arranged in a circular array on the bottom surface of the disc. An exhaust port 241 that runs through the inside and outside is provided on the outer side wall of the water-blocking protrusions. The refining sheet covers the upper side of the air injection core.

[0022] The air injection tube assembly 300 is composed of a main air tube 310 and a branch air tube 320. The main air tube passes through the base and extends into the water injection chamber, while the branch air tubes are connected to the bottom of all the air injection cores.

[0023] In this embodiment, the main air pipe is connected to the air pump, providing a continuous air supply to the air injection core within the foaming unit. The water injection pipe is connected to the water supply line for a continuous water supply. When water enters the outlet at a high pressure, the flow velocity increases dramatically due to the small orifice diameter. After the high-speed water flow impacts the bottom surface of the disc, it diffuses outward and is dispersed into multiple streams by the water-blocking protrusions. The space for water flow increases dramatically, the water pressure decreases, and a large amount of gas is emitted from the exhaust port. This gas mixes with the water and passes through the refining plate at high speed, completely refining the bubbles. A large number of bubbles are ejected from the foaming unit along with the water flow. By adjusting the water pressure, the final ejection velocity of the water flow is maintained between 5 and 8 meters per second.

[0024] See Figure 3Specifically, the water outlet is divided into an upper section 151, a middle section 152, and a lower section 153, with the diameter decreasing step by step. The finer plate is installed in the upper section, and the disc is located in the middle section. A limiting plate 211 and a retaining spring 212 are fixed on the air injection core. A spring 213 is connected between the limiting plate and the upper cover. The spring is in a compressed state, and the water-blocking protrusion abuts against the stepped part of the middle section.

[0025] See Figure 4 Specifically, a concentric ring 214 is fitted on the gas injection core. The outer wall of the concentric ring is coaxially fitted with the lower segment, and several through holes 215 are formed on the concentric ring.

[0026] Specifically, the thinning sheet is divided into a first thinning sheet 221 and a second thinning sheet 222. A first pressing ring 223, a second pressing ring 224 and an end cap 225 are stacked sequentially in the upper segment. The first thinning sheet is clamped between the first pressing ring and the second pressing ring, and the second thinning sheet is clamped between the second pressing ring and the end cap. The end cap is fixedly connected to the upper cover.

[0027] This embodiment also discloses a hollow fiber washing and drying device (see...). Figure 5 The device includes a washing and drying chamber 10, with the aforementioned cleaning module located at the bottom of its inner cavity. An overflow pipe 20 is located on the upper side of the inner cavity, and a filter 30 is located at the inner opening of the overflow pipe. The washing and drying chamber in this hollow fiber washing and drying equipment is a conventional structure. By introducing the cleaning module and overflow pipe, the hollow fibers can be subjected to a water flow impact effect during the washing mode. The high-speed water jet from the cleaning module, mixed with a large number of fine bubbles, can impact clumped fibers. The continuously rising bubbles also continuously provide a disturbance effect to the fibers in the water, which not only prevents fiber clumping but also carries away light impurities adsorbed on the fibers. These light impurities are discharged from the overflow pipe with the water flow.

[0028] This invention can be modified in many ways, as will be apparent to those skilled in the art, and such modifications are not considered to depart from the scope of this invention. All such modifications that are obvious to those skilled in the art are included within the scope of these claims.
