Description

Technical Field

[0001] This utility model relates to the technical field of impurity removal devices, specifically to a lyocell fiber coagulation bath impurity removal device. Background Technology

[0002] Lyocell fiber, as a highly regarded regenerated cellulose fiber, is increasingly widely used in the textile industry due to its excellent moisture absorption and breathability, high strength, and environmentally friendly biodegradable properties. In the production process of lyocell fiber, the coagulation bath stage is crucial. However, the coagulation bath is prone to contamination by various impurities. These impurities originate from fine particles and incompletely dissolved substances carried by the raw materials themselves; on the other hand, erosion and flaking from production equipment pipelines, as well as dust from the external environment, accumulate in the coagulation bath during production. Traditional methods for removing impurities from the lyocell fiber coagulation bath have significant shortcomings. When using static filters, impurities easily accumulate and clog the filter pores after prolonged operation, causing a sharp drop in filtration efficiency. Therefore, to solve these problems, improve the efficiency and quality of impurity removal in the lyocell fiber coagulation bath, and reduce losses, this utility model has been developed. Utility Model Content

[0003] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a lyocell fiber coagulation bath impurity removal device, comprising: a collection tank for collecting the removed lyocell fiber coagulation bath; a filter structure, the bottom of which is fixedly connected to the top of the collection tank, the filter structure intercepting impurities in the lyocell fiber coagulation bath by means of obstruction; a stirring structure, the bottom of which is fixedly connected to the top of the filter structure, the stirring structure fully mixing the material by rotating the lyocell fiber coagulation bath; the filter structure includes a support frame, the outer wall of which is fixedly connected to the outer wall of the collection tank, a drive motor fixedly connected to the outer wall of the support frame, a cam fixedly connected to the output shaft of the drive motor, a connecting rod rotatably connected to the outer wall of the cam, a filter plate rotatably connected to the outer wall of the connecting rod, and a spring plate fixedly connected to the outer wall of the filter plate.

[0004] Preferably, the bottom of the spring sheet is fixedly connected to the top of the support frame. The filter structure adopts a unique dynamic design, which uses a drive motor, cam, and connecting rod to drive the filter plate to move up and down reciprocally. With the spring sheet buffering and resetting, this dynamic shaking makes it difficult for impurities to accumulate on the filter plate and clog the filter holes, effectively avoiding the problem of a sharp drop in filtration efficiency caused by impurity accumulation in traditional static filters.

[0005] Preferably, the stirring structure includes a stirring tank, and a stirring device is rotatably connected to the inner wall of the stirring tank.

[0006] Preferably, the stirring device includes a rotary motor, a stirring frame is fixedly connected to the outer wall of the rotary motor, and a stirring plate is fixedly connected to the outer wall of the stirring frame.

[0007] Preferably, a stirring blade is fixedly connected to the outer wall of the stirring plate, and the stirring blade is arranged in a linear array along the outer wall of the stirring plate.

[0008] Preferably, the outer wall of the rotary motor is fixedly connected to the outer wall of the mixing tank, and the inner wall of the mixing tank is sealed to the output shaft of the rotary motor by a sealing ring.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. This utility model features a unique dynamic design for its filter structure. A drive motor, cam, and connecting rod propel the filter plate in a reciprocating motion, which is further aided by spring plates for buffering and resetting. This dynamic vibration prevents impurities from accumulating on the filter plate and clogging the filter pores, effectively avoiding the problem of a sharp drop in filtration efficiency caused by impurity accumulation in traditional static filters. It maintains a stable and efficient filtration state, reduces the time cost of frequent equipment shutdowns for filter plate cleaning, and ensures continuous production.

[0011] 2. This utility model, by setting up a stirring structure, creates a closed and stable environment for stirring operations in the stirring tank, preventing material splashing and waste and pollution; the rotary motor drives the stirring frame, stirring plate and linear array of stirring blades to rotate at high speed, which not only creates strong convection to promote material circulation and avoid impurity sedimentation, but also enhances the shearing effect, which can break up impurity agglomerates and make impurities evenly dispersed in the coagulation bath, which is conducive to the precise interception of impurities in the subsequent filtration stage, improves the accuracy of impurity removal, and ensures the purification quality of the coagulation bath.

Example

[0018] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a lyocell fiber coagulation bath impurity removal device, comprising: a collection tank 1, used to collect the lyocell fiber coagulation bath after impurity removal; a filter structure 2, the bottom of which is fixedly connected to the top of the collection tank 1, the filter structure 2 intercepting impurities in the lyocell fiber coagulation bath by means of obstruction; a stirring structure 3, the bottom of which is fixedly connected to the top of the filter structure 2, the stirring structure 3 fully mixing the material by rotating the lyocell fiber coagulation bath; the filter structure 2 includes a support frame 21, the outer wall of the support frame 21 being fixedly connected to the outer wall of the collection tank 1, a drive motor 22 being fixedly connected to the outer wall of the support frame 21, a cam 23 being fixedly connected to the output shaft of the drive motor 22, a connecting rod 24 being rotatably connected to the outer wall of the cam 23, a filter plate 25 being rotatably connected to the outer wall of the connecting rod 24, and a spring plate 26 being fixedly connected to the outer wall of the filter plate 25.

[0019] The bottom of the spring plate 26 is fixedly connected to the top of the support frame 21. During use, the coagulated bath, after being stirred evenly, flows into the filter structure 2. The support frame 21 of the filter structure 2 stands firmly on the outer wall of the collection tank 1, playing a key role in supporting and bearing the other components. The drive motor 22 starts working, and its output shaft drives the cam 23 to rotate at a constant speed. The cam 23 is connected to the connecting rod 24 by rotation, which drives the filter plate 25 to move up and down. The filter plate 25 is connected to the top of the support frame 21 by the spring plate 26. When the filter plate 25 is pulled up and down by the cam 23, the spring plate 26 plays a buffering and resetting role. In this dynamic process, the filter plate 25 effectively blocks impurities, and the shaking can also prevent impurities from clogging the filter holes, allowing impurities to remain on the top of the filter plate. The purified coagulated bath passes through the filter plate 25 and flows down into the collection tank 1.

[0020] The stirring structure 3 includes a stirring tank 31, and a stirring device 32 is rotatably connected to the inner wall of the stirring tank 31.

[0022] A stirring plate 325 is fixedly connected to the outer wall of the stirring plate 324. The stirring plate 325 is arranged linearly along the outer wall of the stirring plate 324. During use, the lyocell fiber coagulation bath containing impurities is first transported to the stirring tank 31 of the stirring structure 3. The stirring tank 31 provides a closed and stable space for the entire stirring operation, preventing material from splashing out. Its inner wall is rotatably connected to the stirring device 32 to ensure smooth stirring. The core component of the stirring device 32, the rotary motor 321, is started. The sealing ring 322 can effectively prevent the liquid inside the stirring tank 31 from leaking out. The motor drives the stirring frame 323, which is fixedly connected to it, to rotate at high speed. The stirring plate 324 fixed on the stirring frame 323 cuts into the coagulation bath over a large area, creating strong convection, promoting the circulation of materials, and preventing impurities from settling and accumulating. Moreover, the stirring plate 325 arranged linearly on the outer wall of the stirring plate 324 enhances the shearing effect on the materials by high-speed rotation, breaking up any possible impurity agglomerates, allowing the impurities to be evenly dispersed in the coagulation bath, making them fully integrated, which is beneficial for subsequent precise filtration.

[0024] Working principle:

[0025] During use, the lyocell fiber coagulation bath containing impurities is first transported to the mixing tank 31 of the mixing structure 3. The mixing tank 31 provides a closed and stable space for the entire mixing operation, preventing material from splashing out. Its inner wall is rotatably connected to the mixing device 32 to ensure smooth mixing. The core component of the mixing device 32, the rotary motor 321, is started. The sealing ring 322 can effectively prevent the liquid inside the mixing tank 31 from leaking out. The motor drives the mixing frame 323, which is fixed to it, to rotate at high speed. The mixing plate 324 fixed on the mixing frame 323 cuts into the coagulation bath over a large area, creating strong convection and promoting the circulation of materials to avoid the accumulation of impurities. Moreover, the linear array of mixing blades 325 on the outer wall of the mixing plate 324 enhances the shearing effect on the materials by high-speed rotation, breaking up any possible impurity agglomerates and allowing the impurities to be evenly dispersed in the coagulation bath, so that they can be fully integrated, which is conducive to subsequent precise filtration.

[0026] During use, the well-stirred coagulation bath flows into the filter structure 2. The support frame 21 of the filter structure 2 stands firmly on the outer wall of the collection tank 1, playing a key role in supporting and bearing the other components. The drive motor 22 starts working, and its output shaft drives the cam 23 to rotate at a constant speed. The cam 23 is connected to the connecting rod 24, which drives the filter plate 25 to move up and down. The filter plate 25 is connected to the top of the support frame 21 by the spring plate 26. When the filter plate 25 is pulled up and down by the cam 23, the spring plate 26 plays a buffering and resetting role. In this dynamic process, the filter plate 25 effectively blocks impurities, and the shaking can also prevent impurities from clogging the filter holes, leaving the impurities on the top of the filter plate. The purified coagulation bath passes through the filter plate 25 and flows down into the collection tank 1.
