Description

Technical Field

[0001] The utility model relates to the technical field of ultra-high molecular weight polyethylene wet production equipment, in particular to a polymer material cleaning device. Background Art

[0002] At present, in the preparation process of polymer materials represented by ultra-high molecular weight polyethylene materials (for example, ultra-high molecular weight polyethylene fibers, ultra-high molecular weight polyethylene films, etc.), the wet process occupies the mainstream position. This process requires the use of a large amount of paraffin oil, white oil, mineral oil, kerosene, etc. as solvents during the preparation process. After the preparation of the polymer material (wire or sheet or membrane material), the solvent on the surface of the material needs to be removed. However, since the above solvents are all spinning solvents with high boiling points and are not easy to volatilize, extraction devices are often used to remove the solvent on the polymer material by extraction. After the existing extraction device extracts and removes the solvent from the polymer material, although most of the solvent on the surface of the polymer material has been removed, there will be residual extractant on its surface. The extractant is mostly toxic, harmful and easy to volatilize, which not only seriously affects the health of production personnel, but also brings great environmental and safety pressure.

[0023] In order to further understand the application content, features and effects of the present application, the following embodiments are cited and described in detail with reference to the accompanying drawings.

[0024] Reference Figure 1 , Figure 1 : is a structural schematic diagram of a polymer material cleaning device in an embodiment, and the polymer material cleaning device in this embodiment comprises an extraction mechanism 1, an extraction liquid recovery mechanism 2, a cleaning mechanism 3 and a conveying mechanism 4. The extraction mechanism 1, the extraction liquid recovery mechanism 2 and the cleaning mechanism 3 are sequentially arranged along the material conveying direction of the conveying mechanism 4. The extraction mechanism 1 has an extraction working area, the extraction liquid recovery mechanism 2 has an extraction liquid recovery area, and the cleaning mechanism 3 has an extraction liquid cleaning area. The conveying mechanism 4 conveys the material 100 sequentially through the extraction working area for extraction and removal of solvent, the extraction liquid recovery area for preliminary removal of extraction liquid and the extraction liquid cleaning area for secondary removal of extraction liquid.

[0025] The polymer material cleaning device in this embodiment is used to remove the solvent attached to the ultra-high molecular weight polyethylene material during the wet process production. The material 100 described in this embodiment is the ultra-high molecular weight polyethylene material obtained by the wet process production. The material 100 can be a wire, a sheet or a film material. The conveying mechanism 4 conveys the material 100 so that it passes through the extraction mechanism 1, the extraction liquid recovery mechanism 2 and the cleaning mechanism 3 in sequence. The extraction mechanism 1 has an extraction working area, and there is an extraction liquid in the extraction working area. When the material 100 passes through the extraction working area, the extraction liquid extracts the solvent from the material 100, thereby achieving the effect of removing the solvent. After the extraction is completed, the material 100 passes through the extraction liquid recovery area of ​​the extraction liquid recovery mechanism 2. When the material 100 passes through the extraction liquid recovery area, the extraction liquid on it is recovered by the extraction liquid recovery mechanism 2 to complete the preliminary removal of the extraction liquid. There is a cleaning liquid in the extraction liquid cleaning area. When the material 100 passes through the extraction liquid cleaning area of ​​the cleaning mechanism 3, the cleaning liquid removes the residual extraction liquid on the material 100 for a second time. In this way, the polymer material cleaning device of this embodiment can not only remove the solvent on the material 100, but also remove the extract on the material 100 through the extract recovery mechanism 2 and the cleaning mechanism 3, thereby completing the cleaning of the material 100, improving the product quality, and avoiding the harm caused by the solvent or extract residue. Specifically, the conveying mechanism 4 is an existing wire or sheet conveying mechanism, which conveys the material 100 so that the material 100 passes through the extraction mechanism 1, the extract recovery mechanism 2 and the cleaning mechanism 3 in sequence. The conveying mechanism 4 includes a feeding end and a receiving end, and the extraction mechanism 1, the extract recovery mechanism 2 and the cleaning mechanism 3 are respectively located between the feeding end and the receiving end. The conveying direction of the conveying mechanism 4 described in the present application is also the moving direction of the material 100, that is, the connecting direction from the feeding end to the receiving end.

[0026] Re-reference Figure 1Preferably, the extraction mechanism 1 includes an extraction main body 11, an extraction guide member 12 and an extraction liquid circulation member 13, the extraction guide member 12 includes a plurality of extraction guide rollers, the plurality of extraction guide rollers are sequentially arranged in the extraction main body 11 along the material conveying direction of the conveying mechanism 4, and the guide ends of two adjacent extraction guide rollers face each other, that is, a part of the extraction guide rollers are arranged at the top of the extraction main body 11, and their guide ends face downward, while another part of the extraction guide rollers are arranged at the bottom of the extraction main body 11, and their guide ends face upward, and the guide ends of one part of the extraction guide rollers are lower than the guide ends of the other part of the extraction guide rollers. It can be understood that, through the guiding effect of the plurality of extraction guide rollers, the material 100 does not move simply linearly in the extraction main body 11, but is guided by the extraction guide rollers to reciprocate up and down while moving along the material conveying direction of the conveying mechanism 4, and there is extraction liquid in the extraction main body 11, which can increase the contact time between the material 100 and the extraction liquid, and ensure that the solvent on the material 100 is fully extracted and removed. The extraction liquid circulation part 13 includes an extraction liquid purification treatment device and an extraction liquid circulation pipeline, and the extraction liquid circulation pipeline is connected to the extraction liquid purification treatment device and the extraction main body 11 respectively. That is to say, through the setting of the extraction liquid purification treatment device, the extraction liquid purification treatment device is equivalent to a liquid pump, so that the extraction liquid in the extraction main body 11 and the extraction liquid circulation pipeline can flow, and the flow direction of the extraction liquid in the extraction main body 11 is opposite to the moving direction of the material 100, so that when the material 100 moves, it can be more fully in contact with the extraction liquid, thereby improving the solvent removal effect. Furthermore, the extraction guide rollers are all active rollers, which effectively prevent the material 100 from being broken or damaged due to traction resistance. It should be particularly noted that in other embodiments, the number of extraction mechanisms 1 can be multiple, and multiple extraction mechanisms 1 are arranged in sequence along the conveying direction of the material 100. That is to say, through the setting of multiple extraction mechanisms 1, the material 100 can be extracted multiple times to remove the solvent, thereby further improving the solvent removal effect to ensure that the solvent on the material 100 is removed as cleanly as possible. Specifically, an ultrasonic generator and a temperature control device are also provided in the extraction main body 11. The temperature control device is used to adjust the temperature of the extraction liquid in the extraction main body 11. It can be personalized according to different extraction liquids and material components to improve the extraction efficiency and reduce the amount and consumption of the extraction liquid. At the same time, the ultrasonic generator can send ultrasonic waves to the material in the extraction liquid to further improve the extraction efficiency.

[0027] Refer to Figure 2 , Figure 2Schematic diagram of the structure of the extraction recovery mechanism in the embodiment. Preferably, the extraction liquid recovery mechanism 2 includes an extrusion component 21 and a collection component 22. The extraction mechanism 1, the extrusion component 21 and the cleaning mechanism 3 are sequentially arranged along the material conveying direction of the conveying mechanism 4, and the collection component 22 is connected to the extrusion component 21. When the conveying mechanism 4 conveys the material 100 through the extrusion component 21, the extrusion end of the extrusion component 21 squeezes the surface of the material 100 and squeezes the extraction liquid on the surface into the collection component 22. In specific application, after the material 100 is extracted and the solvent is removed in the extraction working area, the conveying mechanism 4 conveys the material 100 into the extraction liquid recovery mechanism 2 for preliminary removal of the extraction liquid. In this embodiment, the number of the extrusion components 21 is two, and the two extrusion components 21 are respectively arranged at the feed port and the discharge port of the extraction liquid recovery mechanism 2. That is to say, when the material 100 enters the extraction liquid recovery mechanism 2, the extrusion component 21 located at the feed port squeezes the material 100, scrapes off the extraction liquid on the material 100, and makes the extraction liquid flow back to the extraction mechanism 1. When the material 100 is ready to leave the extraction liquid recovery mechanism 2, the extrusion component 21 located at the discharge port squeezes the material 100, scrapes the extraction liquid on the material 100 and squeezes it into the collection component 22 for collection. In this way, the material 100 is squeezed twice to scrape off the extraction liquid thereon, thereby achieving preliminary removal of the extraction liquid on the material. At the same time, the extraction liquid scraped off from the material 100 flows into the extraction mechanism 1 and the collection component 22 for recycling, thereby reducing the consumption of the extraction liquid and reducing the production cost.

[0028] Re-reference Figure 2 Preferably, the extrusion assembly 21 includes a first pressing roller 211 and a second pressing roller 212, which are arranged opposite to each other. When the material 100 passes between the first pressing roller 211 and the second pressing roller 212, the first pressing roller 211 and the second pressing roller 212 jointly extrude the material 100. In specific applications, the first pressing roller 211 and the second pressing roller 212 are both active rollers. When the first pressing roller 211 and the second pressing roller 212 squeeze and scrape the extract from the material 100, the first pressing roller 211 and the second pressing roller 212 also rotate synchronously, thereby effectively preventing the material 100 from being broken or damaged due to traction resistance, and improving the transmission quality of the material 100. In this way, the extract on the material 100 is scraped off by the extrusion assembly 21, and the scraped extract is recovered by the collection assembly 22, which is substantially equivalent to forming an extract recovery area in the extract recovery mechanism 2.

[0029] Re-reference Figure 2Preferably, the collecting assembly 22 is connected to the extraction working area, and the height of the collecting assembly 22 is higher than the extraction working area. Since the height of the collecting assembly 22 is higher than the extraction working area, the extract collected in the collecting assembly 22 can naturally flow back to the extraction working area under the action of gravity, that is, the extract squeezed into the collecting assembly 22 by the squeezing assembly 21 can be returned to the extraction mechanism 1 for recycling, further reducing the consumption of the extract and reducing the production cost.

[0030] Re-reference Figure 2 Preferably, the collecting component 22 includes a collecting tank 221 and a circulation channel 222. The collecting tank 221 is connected to the extrusion component 21, and the two ends of the circulation channel 222 are connected to the collecting tank 221 and the extraction working area respectively. The extrusion end of the extrusion component 21 extrude the surface of the material 100 and squeeze the extract on the surface into the collecting tank 221, and the extract in the collecting tank 221 flows back to the extraction working area through the circulation channel 222. In specific applications, the collecting tank 221 is used to collect the extract scraped from the material 100 by the extrusion component 21, and the extract in the collecting tank 221 flows back to the extraction working area through the circulation channel 222 for recycling. Furthermore, a switch valve is provided on the circulation channel 222, and when the switch valve is opened, the extract in the collecting tank 221 can flow back to the extraction working area. When it is necessary to clean the extract recovery mechanism 2, the switch valve can be closed to disconnect the extract recovery mechanism 2 from the extraction working area.

[0031] Re-reference Figure 1-2 Preferably, the extract recovery mechanism 2 further includes a drainage component 23, one end of the drainage component 23 is close to the extrusion end of the extrusion component 21, and the other end of the drainage component 23 is close to the collection component 22. In specific applications, the number of drainage components 23 in this embodiment is two, and the two drainage components 23 are both arranged in the extract recovery mechanism 2 and are respectively close to the feed port and the discharge port of the extract recovery mechanism 2. It can be understood that when the material 100 passes through the extrusion component 21 located at the discharge port, the extract squeezed out of the material 100 by the extrusion component 21 flows into the collection pool 221 through the drainage component 23, and the drainage component 23 arranged at the feed port can drain the extract squeezed by the extrusion component 21 passing through the feed port into the collection pool 221, so as to avoid the extract remaining on the wall of the collection pool 221 and improve the recovery rate of the extract. Specifically, the drainage component 23 is a drainage inclined block, which has a drainage inclined surface, and the inclination angle of the drainage inclined surface is 15° to 25°.

[0032] Re-reference Figure 1-2Preferably, the cleaning mechanism 3 includes a cleaning body 31 and an ultrasonic component 32. The extraction liquid cleaning area is located in the cleaning body 31, and the output end of the ultrasonic component 32 faces the material 100 in the extraction liquid cleaning area. In specific applications, the cleaning body 31 is a cleaning pool, which contains cleaning liquid. When the material 100 enters the cleaning body 31, it is immersed in the cleaning liquid for cleaning to further remove the extraction liquid on the material 100. The cleaning pool is also the extraction liquid cleaning area. An ultrasonic component 32 is provided in the cleaning pool. In this embodiment, the ultrasonic component 32 is an ultrasonic generator. When the material 100 is immersed in the cleaning liquid, in addition to the cleaning effect caused by the traction of the conveying mechanism 4 to drive the material 100 to move in the cleaning liquid, the ultrasonic generator can further enhance the cleaning effect of the extraction liquid on the material 100. Furthermore, a temperature control device is provided in the cleaning pool to enhance the cleaning effect of the cleaning liquid on the extraction liquid by changing the temperature of the cleaning liquid. It should be noted that in other embodiments, the number of cleaning mechanisms 3 can be multiple, and the multiple cleaning mechanisms 3 are arranged in sequence along the conveying direction of the material 100. That is to say, through the arrangement of multiple cleaning mechanisms 3, the material 100 can be cleaned multiple times, thereby further improving the cleaning effect of the extraction liquid to ensure that the extraction liquid on the material 100 is removed as cleanly as possible.

[0033] Re-reference Figure 1-2 Preferably, the cleaning mechanism 3 further includes a cleaning guide assembly 34, which is disposed in the cleaning main body 31, and the guide end of the cleaning guide assembly 34 contacts the material 100 of the cleaning main body 31 and presses the material 100 into the extraction liquid cleaning area. In specific applications, the cleaning guide assembly 34 is a guide roller, and the number of guide rollers in this embodiment is two, and the guide end of the guide roller is immersed in the cleaning liquid, that is, when the material 100 enters the cleaning mechanism 3, the guide roller presses the material 100 into the cleaning liquid, so that the material 100 is fully immersed in the cleaning liquid for transmission, so that the cleaning liquid and the material 100 are fully in contact, thereby completing the cleaning of the extraction liquid, and the two guide rollers are active rollers, which effectively prevent the material 100 from being broken or damaged due to the traction resistance of the cleaning liquid, thereby improving the production quality.

[0034] Re-reference Figure 1-2Preferably, the polymer material cleaning device further comprises a drying mechanism 5, the feed port of the drying mechanism 5 is connected to the discharge port of the cleaning mechanism 3, the drying mechanism 5 has a drying operation area, and the conveying mechanism 4 conveys the material 100 through the drying operation area for drying and removing the cleaning liquid. In specific application, the drying mechanism 5 comprises a drying bin and a plurality of hot air blowers. When the material 100 enters the drying bin after being cleaned by the cleaning mechanism 3, the hot air blower dries the material 100 by blowing hot air, so that the residual cleaning liquid on it evaporates naturally, thereby achieving the effect of removing the cleaning liquid. Furthermore, along the conveying direction of the material 100, the drying bin can be divided into a plurality of drying zones with different temperatures, and the temperature of different drying zones can be adjusted by adjusting the output power of the hot air blower. In this way, when the material 100 passes through the drying bin for drying, the drying temperature of the material 100 when passing through different drying zones is different. The temperature of each stage is independently controlled by a multi-stage and multi-bin method, and differential drying is achieved to achieve the purpose of thorough drying, thereby improving the drying efficiency and drying effect.

[0035] Re-reference Figure 1-2 Preferably, the cleaning mechanism 3 further includes a cleaning liquid recovery component 33, which is disposed at the discharge port of the cleaning main body 31. When the material 100 passes through the discharge port of the cleaning main body 31, the cleaning liquid recovery component 33 squeezes the surface of the material 100 and squeezes the cleaning liquid on the surface into the extraction liquid cleaning area. In specific application, the cleaning liquid recovery component 33 includes a drainage bevel, a drainage channel and two relatively arranged cleaning liquid recovery rollers. The two relatively arranged cleaning liquid recovery rollers are arranged at the discharge port of the cleaning main body 31, and the drainage bevel is arranged between the cleaning main body 31 and the drying bin. The two ends of the drainage channel are respectively connected to the drainage bevel and the cleaning main body 31. It can be understood that when the material 100 is transported away from the cleaning main body 31 after cleaning, the two relatively arranged cleaning liquid recovery rollers squeeze the material 100, scrape the cleaning liquid on the material 100 and return it to the cleaning main body 31 for recycling. Moreover, when the material 100 enters the drying bin, a pressure roller is also arranged at the feed port of the drying bin to further scrape off the residual cleaning liquid on the material 100, reduce the drying pressure of the subsequent drying bin, and improve the drying effect and drying efficiency. The cleaning liquid scraped by the pressure roller at the feed port of the drying bin is drained through the drainage bevel, and then returns to the cleaning main body 31 through the drainage channel, thereby reducing the consumption of cleaning liquid and reducing production costs.

[0036] In summary, the extraction mechanism has an extraction working area, and there is an extraction liquid in the extraction working area. When the material passes through the extraction working area, the extraction liquid extracts the solvent from the material, thereby achieving the effect of removing the solvent. After the extraction is completed, the material passes through the extraction liquid recovery area of ​​the extraction liquid recovery mechanism. When the material passes through the extraction liquid recovery area, the extraction liquid on it is recovered by the extraction liquid recovery mechanism to complete the preliminary removal of the extraction liquid. There is a cleaning liquid in the extraction liquid cleaning area. When the material passes through the extraction liquid cleaning area of ​​the cleaning mechanism, the cleaning liquid removes the residual extraction liquid on the material for a second time. In this way, the polymer material cleaning device of this embodiment can not only remove the solvent on the material, but also remove the extraction liquid on the material respectively through the extraction liquid recovery mechanism and the cleaning mechanism, thereby completing the cleaning of the material, improving product quality, and avoiding the harm caused by residual solvent or extraction liquid.
