Description

Technical Field

[0001] This invention relates to the field of synthetic latex production technology, and more specifically, to a synthetic latex residue extraction device and method. Background Technology

[0002] Synthetic latex is an aqueous dispersion of polymer particles synthesized by emulsion polymerization. This polymer is a homopolymer or copolymer based on a single, small, vinyl-unsaturated organic compound. Major synthetic latexes include styrene-butadiene latex, butadiene latex, butyl latex, chloroprene latex, ethylene-propylene latex, isoprene latex, nitrile latex, and acrylic latex. The main uses of synthetic latex are in the manufacture of foamed rubber products and impregnated products. It is also widely used in the carpet industry, paper industry, fiber processing, building materials, coatings, pigments, and adhesives.

[0003] Currently, most existing synthetic rubber latex residue extraction devices use filter bags for latex residue extraction. This requires disassembling and reassembling the filter bags during the long extraction process, which inevitably affects the extraction efficiency. At the same time, the latex residue located in the filter bags is inconvenient to collect, which easily leads to resource waste. Summary of the Invention

[0004] To overcome the above shortcomings, this invention provides a synthetic rubber latex residue extraction device and method, aiming to improve upon the problem that most latex residue extraction methods use filter bags. These methods require disassembling and reassembling the filter bags during the long extraction process, which unintentionally affects the extraction efficiency. Furthermore, the latex residue inside the filter bags is inconvenient to collect, easily leading to resource waste.

[0005] This invention is implemented as follows:

[0006] This invention provides a device and method for extracting synthetic rubber latex residue, including a support structure and an extraction structure.

[0007] The support structure includes a support plate and an extraction cylinder. The extraction cylinder is fixed to one side of the top surface of the support plate. The extraction structure includes an annular frame, a lifting component, and an extraction component. Vertical plates are fixed on both sides of the annular frame. The ends of the vertical plates are fixedly connected to the outer surface of the extraction cylinder. A transfer component is installed inside the annular frame. The lifting component is installed on the transfer component, and the extraction component is installed on the lifting component.

[0008] In one embodiment of the present invention, a support member is fixed to the bottom of the support plate. The support member includes a support column and a support pad. The support column is fixed to the bottom of the support plate, and the support pad is fixedly connected to the bottom of the support column. A sleeve and a collection box are also fixed to the top surface of the support plate. The collection box is located on both sides of the sleeve. An inlet pipe and an outlet pipe are respectively connected and fixed to the upper and lower ends of one side of the extraction cylinder. A control valve is installed on the outlet pipe.

[0009] In one embodiment of the present invention, the transfer member includes two threaded rods and a first servo motor. The two threaded rods are rotatably connected inside the annular frame, and one end of each threaded rod rotatably extends through the annular frame to the outside. One end of each threaded rod is connected by a transmission member. The first servo motor is mounted on one side of the annular frame, and the end of the output shaft of the first servo motor is fixed to one of the threaded rods.

[0010] In one embodiment of the present invention, the transmission component includes two transmission wheels and a transmission chain. The two transmission wheels are respectively keyed to one end of the two threaded rods, and the two transmission wheels are connected to each other by the transmission chain.

[0011] In one embodiment of the present invention, the lifting component includes a slider and a hydraulic cylinder. The slider is threadedly connected to two threaded rods, the hydraulic cylinder is mounted on the top surface of the slider, and a connecting frame is fixed to the output end of the hydraulic cylinder. A cover plate is mounted on the connecting frame.

[0012] In one embodiment of the present invention, the extraction component includes a second servo motor, two base plates and two first annular plates. The second servo motor is mounted on the top surface of the cover plate. A rotating rod is mounted at the end of the output shaft of the second servo motor. The rotating rod rotatably passes through the interior of the two base plates. A filter part is fixed between each of the two base plates and the two first annular plates. The two first annular plates are fixed together by a connecting column. The first annular plates are slidably connected to the inner surface of the extraction cylinder.

[0013] In one embodiment of the present invention, the filtration section includes two second annular plates and a filter screen, the filter screen being fixed between the two second annular plates, one second annular plate being fixedly connected to the base plate, and the other second annular plate being fixedly connected to the first annular plate, and a slag discharge pipe fitting being fixed to the bottom of the base plate.

[0014] In one embodiment of the present invention, the slag discharge pipe includes a hollow pipe and a slag discharge pipe. The hollow pipe is fixed to the inner bottom surface of the base plate. The slag discharge pipe is connected to the hollow pipe through a rotary joint. A sealing cap is threaded to the end of the slag discharge pipe.

[0015] In one embodiment of the present invention, a scraper is fixed to the surface of the rotating rod, the scraper is slidably connected to the surface of the base plate and the filter screen, and a plug-in post matching the plug sleeve is fixed to the bottom of the base plate.

[0016] This application provides a method for extracting synthetic rubber latex residue, which utilizes the aforementioned synthetic rubber latex residue extraction device and includes the following steps:

[0017] Step one: First, the produced synthetic latex is fed into the extraction cylinder through the feed pipe. The synthetic latex then passes through two filters in sequence.

[0018] Step two: After a long filtration process, latex residue will remain on the surface of the bottom plate. At this point, the hydraulic cylinder retracts upwards, lifting the two bottom plates out of the extraction cylinder. Then, the first servo motor drives one threaded rod to rotate, which, under the action of the transmission component, drives another threaded rod to rotate. This causes the slider to move on the surface of the threaded rod, simultaneously moving the hydraulic cylinder.

[0019] Step 3: When the insertion post at the bottom of the base plate is aligned with the insert sleeve, the hydraulic cylinder works again to move the extraction component downwards, inserting the insertion post into the interior of the insert sleeve for positioning.

[0020] Step 4: At this point, rotate the slag discharge pipe so that the end of the slag discharge pipe is above the collection box, and then open the sealing cap at the end of the slag discharge pipe. In this way, the latex residue on the bottom plate surface will flow into the inside of the collection box for collection.

[0021] Step 5: Here, the second servo motor drives the rotating rod to rotate, and the scraper follows the rotation to further clean the latex residue on the bottom plate and filter screen, thus completing the latex residue extraction.

[0022] The beneficial effects of this invention are as follows: The synthetic latex extraction device and method obtained by the above design involve transporting the produced synthetic latex into the extraction cylinder. The synthetic latex then passes through two filter sections sequentially. After prolonged filtration, the latex residue remains on the surface of the bottom plate. The extraction component is then removed from the extraction cylinder via a lifting device. The slag discharge pipe is then rotated so that its end is positioned above the collection box to collect the latex residue, thus completing the extraction process. This eliminates the need for repeated disassembly and assembly during latex residue extraction, saving time and improving extraction efficiency. Furthermore, the easy collection of latex residue facilitates its reuse, reducing resource waste. Attached Figure Description

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example: Please refer to Figure 1-5 The present invention provides a technical solution: a device and method for extracting synthetic rubber latex residue, comprising a support structure 100 and an extraction structure 200.

[0032] Please see Figures 1-3 The support structure 100 includes a support plate 110 and an extraction cylinder 130, with the extraction cylinder 130 fixed to one side of the top surface of the support plate 110.

[0033] A support member 120 is fixed to the bottom of the support plate 110. The support member 120 includes a support column 121 and a support pad 122. The support column 121 is fixed to the bottom of the support plate 110, and the support pad 122 is fixedly connected to the bottom of the support column 121. A sleeve 140 and a collection box 150 are also fixed to the top surface of the support plate 110. The collection box 150 is located on both sides of the sleeve 140. The upper and lower ends of one side of the extraction cylinder 130 are respectively connected and fixed to the feed pipe 131 and the discharge pipe 132. A control valve is installed on the discharge pipe 132. The feed pipe 131 and the discharge pipe 132 facilitate the input and output of raw materials.

[0034] Please see Figures 1-5 The extraction structure 200 includes an annular frame 220, a lifting component 240, and an extraction component 250. Vertical plates 210 are fixed on both sides of the annular frame 220. The ends of the vertical plates 210 are fixedly connected to the outer surface of the extraction cylinder 130. A transfer component 230 is installed inside the annular frame 220. The lifting component 240 is installed on the transfer component 230, and the extraction component 250 is installed on the lifting component 240.

[0035] The transfer component 230 includes two threaded rods 231 and a first servo motor 232. The two threaded rods 231 are rotatably connected inside the annular frame 220, with one end of each threaded rod 231 extending through the annular frame 220 to the outside. One end of each threaded rod 231 is connected via a transmission component 233. The first servo motor 232 is mounted on one side of the annular frame 220, and the end of the output shaft of the first servo motor 232 is fixed to one of the threaded rods 231. The transmission component 233 includes two transmission wheels 2331 and a transmission chain 2332. The two transmission wheels 2331 are keyed to one end of each of the two threaded rods 231, and the two transmission wheels 2331 are connected via the transmission chain 2332. The first servo motor 232 and the transmission component 233 drive the two threaded rods 231 to rotate, allowing the slider 241 to move back and forth on the surface of the threaded rods 231, thus facilitating the transfer.

[0036] The lifting component 240 includes a slider 241 and a hydraulic cylinder 242. The slider 241 is threadedly connected to two threaded rods 231. The hydraulic cylinder 242 is installed on the top surface of the slider 241. A connecting frame 243 is fixed to the output end of the hydraulic cylinder 242, and a cover plate 244 is installed on the connecting frame 243. The hydraulic cylinder 242 facilitates the removal of the extraction component 250 from the extraction cylinder 130, thereby facilitating the collection of latex residue. The extraction component 250 includes a second servo motor 251, two base plates 253, and two first annular plates 254. The second servo motor 251 is installed on the top surface of the cover plate 244. A rotating rod 252 is installed at the end of the output shaft of the second servo motor 251. The rotating rod 252 rotates through the interior of the two base plates 253. The top surface of the base plates 253 forms a frustum-shaped protrusion to facilitate... The latex residue flows through the container. A filter section 255 is fixed between each of the two bottom plates 253 and the two first annular plates 254. The two first annular plates 254 are fixed together by a connecting column 256. The first annular plates 254 are slidably connected to the inner surface of the extraction cylinder 130. The filter section 255 includes two second annular plates 2551 and a filter screen 2552. The filter screen 2552 is fixed between the two second annular plates 2551. One second annular plate 2551 is fixedly connected to the bottom plate 253, and the other second annular plate 2551 is fixedly connected to the first annular plate 254. A slag discharge pipe 260 is fixed to the bottom of the bottom plate 253. The aperture of the two filter screens 2552 decreases sequentially from top to bottom, allowing for the filtration of latex residue of different particle sizes and more thorough extraction of the latex residue.

[0037] The slag discharge pipe fitting 260 includes a hollow pipe 261 and a slag discharge pipe 263. The hollow pipe 261 is fixed inside the bottom surface of the base plate 253. The slag discharge pipe 263 is connected to the hollow pipe 261 through a rotary joint 262. The end of the slag discharge pipe 263 is threaded with a sealing cap. The rotary joint 262 allows the slag discharge pipe 263 to be rotated easily, thus extending to a more distant location for convenient collection. A scraper 2521 is fixed on the surface of the rotating rod 252. The scraper 2521 is slidably connected to the surfaces of the base plate 253 and the filter screen 2552. The bottom of the base plate 253 is fixed with a plug-in post 2531 that matches the plug sleeve 140. Here, the second servo motor 251 drives the rotating rod 252 and the scraper 2521 to rotate, thereby cleaning the filter screen 2552 and the base plate 253.

[0038] This application provides a method for extracting synthetic rubber latex residue, which utilizes the aforementioned synthetic rubber latex residue extraction device and includes the following steps:

[0039] Step one: First, the produced synthetic latex is fed into the extraction cylinder 130 through the feed pipe 131. At this time, the synthetic latex will pass through two filter screens 2552 in sequence.

[0040] Step two: After a long period of filtration, latex residue will remain on the surface of the bottom plate 253. At this point, the hydraulic cylinder 242 retracts upwards, lifting the two bottom plates 253 out of the extraction cylinder 130. Then, the first servo motor 232 drives one threaded rod 231 to rotate. Then, under the action of the transmission component 233, it drives another threaded rod 231 to rotate, so that the slider 241 will move on the surface of the threaded rod 231, while simultaneously moving the hydraulic cylinder 242.

[0041] Step 3: When the insertion post 2531 at the bottom of the base plate 253 is aligned with the insert sleeve 140, the hydraulic cylinder 242 works again to drive the extraction piece 250 to move downward, inserting the insertion post 2531 into the interior of the insert sleeve 140 for positioning.

[0042] Step 4: At this time, rotate the slag discharge pipe 263 so that the end of the slag discharge pipe 263 is above the collection box 150, and then open the sealing cover at the end of the slag discharge pipe 263. In this way, the latex residue on the surface of the bottom plate 253 will flow into the interior of the collection box 150 for collection.

[0043] Step 5: Here, the second servo motor 251 drives the rotating rod 252 to rotate, and the scraper 2521 follows suit to further clean the latex residue on the surface of the bottom plate 253 and the filter screen 2552, thereby completing the latex residue extraction.

[0044] Specifically, the working principle of the synthetic latex residue extraction device and method is as follows: During use, the produced synthetic latex is conveyed into the extraction cylinder 130 through the feed pipe 131. The synthetic latex then passes through two filter screens 2552 sequentially. After prolonged filtration, latex residue remains on the surface of the bottom plate 253. At this point, the hydraulic cylinder 242 retracts upwards, lifting the two bottom plates 253 out of the extraction cylinder 130. Then, the first servo motor 232 drives one threaded rod 231 to rotate. Then, under the action of the transmission component 233, it drives another threaded rod 231 to rotate. This causes the slider 241 to move on the surface of the threaded rod 231, simultaneously moving the hydraulic cylinder 242. When the insertion post 2531 at the bottom of the bottom plate 253 aligns with the insertion sleeve 140, the hydraulic cylinder 242 operates again, driving... The extraction component 250 moves downwards, inserting the insertion post 2531 into the insertion sleeve 140 for positioning. At this time, the slag discharge pipe 263 is rotated so that its end is above the collection box 150. Then, the sealing cap at the end of the slag discharge pipe 263 is opened, allowing the latex residue on the surface of the bottom plate 253 to flow into the collection box 150 for collection. Here, the second servo motor 251 drives the rotating rod 252 to rotate, and the scraper 2521 follows suit, further cleaning the latex residue on the surface of the bottom plate 253 and the filter screen 2552, thus completing the latex residue extraction. This eliminates the need for repeated disassembly and assembly during latex residue extraction, saving more time and improving extraction efficiency. It also facilitates the collection of latex residue, enabling its reuse and reducing resource waste.

[0045] It should be noted that the specific models and specifications of the first servo motor 232, the hydraulic cylinder 242, and the second servo motor 251 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0046] The power supply and operating principle of the first servo motor 232, the hydraulic cylinder 242, and the second servo motor 251 are clear to those skilled in the art and will not be described in detail here.

[0047] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
