Description

Technical Field

[0001] The present invention relates to the field of phenolic resin processing, and more specifically, to an emulsifying device for phenolic resin. Background Art

[0002] Phenolic resin, also known as bakelite, was originally a colorless or yellowish-brown transparent substance. In the market, it is often added with colorants and appears in colors such as red, yellow, black, green, brown, and blue, in the form of granules or powders. It is resistant to weak acids and weak bases, decomposes when encountering strong acids, corrodes when encountering strong bases, is insoluble in water, and soluble in organic solvents such as acetone and alcohol. It is obtained by polycondensation of phenol aldehyde or its derivatives.

[0003] There is a direct emulsifying and stirring device for water-based resin on the market (Patent No.: CN214681742U). It heats the material inside the housing by means of electric heating and uses the heat conductivity of the material itself for heat transfer. Its heating efficiency for the material is slow, seriously affecting the emulsifying effect of the resin.

[0004] A Chinese patent with the publication number (CN114272779A) discloses an emulsifying device for phenolic resin. Through the coordinated setting of a hot air supply device, an air supply pipe, a connecting pipe, a driving rotation mechanism, a driving lifting mechanism, a jet pipe, and jet holes, and at the same time, through the driving rotation mechanism, the connecting pipe drives the jet pipe to rotate inside the emulsifying tank, the jet pipe can stir the resin and adjust the exhaust position of the high-temperature gas. It also adjusts the height of the jet pipe inside the emulsifying tank through the driving lifting mechanism, so that the high-temperature gas can be fully sprayed inside the resin, thereby improving the emulsifying effect of the resin. However, during the use process, the stirring process of the resin and the emulsifier is very important, which directly affects the quality of the emulsifying effect. The existing device cannot fully stir the resin and the emulsifier according to the emulsifying degree of the resin, resulting in the obtained resin emulsion not meeting the normal use requirements and having a poor use effect.

[0020] (2) By providing a heating mechanism, when emulsifying the resin, the fixedly connected flow-through plate can rotate synchronously, and at this time, hot air can be introduced from an external hot air pipe into the flow-through plate through the air guide pipe, and then into the heating pipe, and flow out from the air permeable holes of the heating pipe to fully heat the mixed liquid in the emulsifying box, improve the emulsifying efficiency, and make the use effect of the emulsified phenolic resin better.

[0021] (3) By providing a stirring mechanism and a cleaning mechanism, when stirring the resin and the emulsion in the emulsifying tank, since the top end of the support plate of the stirring mechanism is fixedly connected with the cleaning mechanism, and the clamping balls of the cleaning mechanism are stuck in the first annular groove and the second annular groove, when the threaded rod rotates, the ball nut seat will slide upward, squeezing the support plate, increasing the angle between the support plate and the first support seat, expanding the stirring range, and enabling the resin and the emulsifier in the edge area of the emulsifying tank to be fully stirred, further improving the emulsifying effect.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Please refer to Figures 1 to 8 , an emulsifying device for phenolic resin, including an emulsifying tank 1, a feed port 2 is arranged on one side of the top of the emulsifying tank 1, a first discharge pipe 3 is arranged on one side of the bottom of the emulsifying tank 1, an air valve 6 is arranged on the front side of the top of the emulsifying tank 1, a circular groove is opened in the middle of the inner top end of the emulsifying tank 1, a heating mechanism 5 is arranged in the middle of the top of the emulsifying tank 1, and a stirring mechanism 4 is arranged inside the emulsifying tank 1;

[0044] Among them, the stirring mechanism 4 includes a servo motor 41 fixedly connected to the middle of the bottom of the emulsifying tank 1, the output end of the servo motor 41 is fixedly connected with a threaded rod 42, the threaded rod 42 penetrates through the inside of the emulsifying tank 1 and is slidably connected with a ball nut seat 43, both ends of the outer circumferential surface of the ball nut seat 43 are fixedly connected with a first support block 44, the ball nut seat 43 is fixedly connected with a first support seat 45 through the first support block 44, a support plate 46 is rotatably connected inside the first support seat 45, a fixing sleeve 47 is fixedly connected to the upper end of the outer circumferential surface of the threaded rod 42, both sides of the outer circumferential surface of the fixing sleeve 47 are fixedly connected with a second support block 48, and the fixing sleeve 47 is rotatably connected with a connecting plate 49 through the second support block 48.

[0045] As Figure 3 , Figure 4 , Figure 5 shown, both ends of the connecting plate 49 are rotatably connected with a connecting seat 491, the connecting seat 491 at one end of the connecting plate 49 is fixedly connected with the connecting plate 49, and the connecting seat 491 at the other end of the connecting plate 49 is fixedly connected with the support plate 46.

[0046] By adopting the above technical solution, when emulsifying the resin, the resin can be poured into the emulsifying tank 1 from the feed port 2, and then the servo motor 41 of the stirring mechanism 4 is started, so that the threaded rod 42 rotates. The connection parts of the servo motor 41, the threaded rod 42 and the emulsifying tank 1 are in a sealed state, and there will be no liquid leakage situation, so that the ball nut seat 43 rotates synchronously, and the fixing sleeve 47 also rotates synchronously. At the same time, the first support block 44 and the second support block 48 are used to drive the support plate 46 and the connecting plate 49 to rotate synchronously respectively, and the connecting plate 49 provides a supporting force for the rotation process of the support plate 46, so that the support plate 46 fully stirs the resin in the emulsifying tank 1, so that the resin is fully emulsified, and the produced phenolic resin product meets the actual requirements and can be used normally.

[0047] As Figure 2 , Figure 3 , Figure 4 shown, the heating mechanism 5 includes a circulation disk 51 rotatably connected to the middle of the top of the emulsifying tank 1, a gas guide pipe 55 is fixedly connected to one side of the top of the circulation disk 51, a plurality of limiting plates 52 are fixedly connected to the outer circumferential surface of the circulation disk 51, and the limiting plates 52 are stuck in the circular groove in the middle of the inner top end of the emulsifying tank 1.

[0048] As Figure 3 , Figure 4 , Figure 5 shown, the inside of the floating stock 51 is in a cavity state. Two heating tubes 56 are fixedly connected to the bottom of the floating stock 51. At both ends of the outer circumferential surface of the two heating tubes 56, limit seats 54 are fixedly connected. In the middle of the limit seat 54, a limit sleeve 53 is fixedly connected. The limit sleeve 53 is sleeved on the outer circumferential surface of the threaded rod 42.

[0049] By adopting the above technical solution, when emulsifying the resin, the floating stock 51 fixedly connected to the threaded rod 42 can rotate synchronously. And at this time, hot air can be introduced into the floating stock 51 from the air duct 55 through an externally connected hot air pipe, and then enter the heating tube 56, and flow out from the air permeable holes of the heating tube 56. When the stirring mechanism 4 stirs the resin and emulsifier in the emulsifying tank 1, the heating tube 56 can rotate synchronously, so that the mixed liquid in the emulsifying tank 1 can be fully heated, the emulsifying efficiency is improved, and the use effect of the emulsified phenolic resin is better.

[0050] As Figure 2 , Figure 3 , Figure 4 shown, a cleaning mechanism 7 is arranged on the inner wall of the emulsifying tank 1. The cleaning mechanism 7 includes a first annular groove 71 and a second annular groove 72 fixedly connected to the upper and lower ends inside the emulsifying tank 1. The top end of the support plate 46 is rotatably connected to a second support seat 73. A fixing plate 74 is fixedly connected to the outside of the second support seat 73. On one side of the outer surface of the fixing plate 74, a plurality of spring telescopic rods 75 are fixedly connected. The fixing plate 74 is fixedly connected to a scraping plate 76 through the plurality of spring telescopic rods 75. At both ends of the scraping plate 76, a plurality of clamping balls 77 are fixedly connected. The clamping balls 77 are respectively rotatably connected to the inside of the first annular groove 71 and the second annular groove 72.

[0051] By adopting the above technical solution, when stirring the resin and the emulsion in the emulsifying tank 1, since the top end of the support plate 46 of the stirring mechanism 4 is fixedly connected with a second support seat 73, and one side of the second support seat 73 is fixedly connected with a spring telescopic rod 75 through a fixing plate 74, and at the same time, one end of the spring telescopic rod 75 is fixedly connected with a clamping ball 77. At this time, the clamping ball 77 is movably clamped in the first annular groove 71. At this time, one end of the support plate 46 is equivalent to being limited. Therefore, when the servo motor 41 is started, the threaded rod 42 will cause the ball nut seat 43 to slide upward under the limited condition, so that the support plate 46 is squeezed, so that the included angle between the support plate 46 and the first support seat 45 becomes larger, and the stirring range is expanded. Furthermore, the resin and the emulsifier in the edge area of the emulsifying tank can be fully stirred, further improving the emulsifying effect. At the same time, during the movement of the clamping ball 77, the fixedly connected scraper 76 will rotate synchronously, and the clamping balls 77 at both ends of the scraper 76 rotate inside the first annular groove 71 and the second annular groove 72 respectively, ensuring the stability of the scraper 76 during rotation. Thus, the scraper 76 cleans the inner wall of the emulsifying tank 1, avoiding the adhesion of the emulsifier to the inner wall of the emulsifying tank 1 during long-term emulsifying operation, resulting in waste of raw materials. At the same time, when adjusting the stirring range, the spring telescopic rod 75 can ensure that the scraper 76 is always tangent to the inner wall of the emulsifying tank 1, and the cleaning operation can be carried out normally.

[0052] As Figure 1 、 Figure 7 shown, a conveying mechanism 8 is arranged on one side of the outer circular surface of the emulsifying tank 1. The conveying mechanism 8 of the emulsifying tank 1 is fixedly connected with a treatment tank 9. The conveying mechanism 8 includes an air extraction pump 81 fixedly connected to one side of the outer circular surface of the emulsifying tank 1. The upper end of the air extraction pump 81 is fixedly connected with a first conveying pipe 82. The first conveying pipe 82 penetrates and is fixedly connected to the inner top of the emulsifying tank 1. The output end of the air extraction pump 81 is fixedly connected with a second conveying pipe 83. The air extraction pump 81 is fixedly connected to the treatment tank 9 through the second conveying pipe 83. One side of the inner bottom of the treatment tank 9 is fixedly connected with a limiting cylinder 84. A treatment pipe 85 is threadedly connected inside the limiting cylinder 84. A plurality of leakage holes 86 are circumferentially formed on the outer circular surface of the treatment pipe 85.

[0053] By adopting the above technical solution, during the emulsification process of the resin, some harmful gases will be generated, such as air pollutants such as formaldehyde, phenol, and sulfuric acid mist. At this time, the conveying mechanism 8 can be started to flow the harmful gases in the emulsifying tank 1 into the treatment tank 9 through the first conveying pipe 82 and the second conveying pipe 83. At the same time, the introduced harmful gases emerge from the leakage holes 86 of the treatment pipe 85 and are introduced into the alkaline solution inside the treatment tank 9 in the form of small bubbles, so that the harmful gases react with the alkaline solution, reducing the pollution problem of direct discharge.

[0054] As Figure 7As shown in the figure, a sealing cover 91 is threadedly connected to the top of the processing tank 9. A second discharge pipe 93 is provided at the middle of the bottom of the processing tank 9. An air outlet pipe 92 is provided on one side of the top of the sealing cover 91. A plurality of cushion blocks are fixedly connected to the middle of the inner wall of the processing tank 9. A filtering mechanism 10 is provided in the middle of the interior of the processing tank 9.

[0055] As Figure 7 shown, the filtering mechanism 10 includes a filter plate 101 placed on the upper surface of the cushion block. A fixing rod 102 is fixedly connected to the middle of the upper surface of the filter plate 101. A first adsorption cotton layer 103 is fixedly connected to the middle of the outer cylindrical surface of the fixing rod 102. A drying cotton layer 104 is fixedly connected to the upper end of the outer cylindrical surface of the fixing rod 102.

[0056] By adopting the above technical solution, after neutralizing the acidic gas generated during the emulsification process with an alkaline solution, the treated gas can be sequentially filtered, adsorbed, and dried by the filter plate 101, the first adsorption cotton layer 103, and the drying cotton layer 104, so that the treated gas meets the gas emission standard and can be directly discharged from the air outlet pipe 92 without polluting the environment. At the same time, when the waste solution in the processing tank 9 needs to be additionally treated, the valve of the second discharge pipe 93 can be opened to discharge the solution inside.

[0057] As Figure 1 、 Figure 7 、 Figure 8 shown, a feeding mechanism 11 is provided on one side of the outer cylindrical surface of the processing tank 9. The feeding mechanism 11 includes a storage tank 111 fixedly connected to one side of the outer cylindrical surface of the processing tank 9. A protective cover 112 is threadedly connected to the top of the storage tank 111. A hydraulic rod 115 is fixedly connected to one side of the top of the protective cover 112. An auxiliary plate 116 is fixedly connected to the top of the hydraulic rod 115. A pull rod 117 is fixedly connected to the bottom of the auxiliary plate 116. The pull rod 117 passes through the interior of the protective cover 112 and is fixedly connected to a support plate 118.

[0058] As Figure 1 、 Figure 7 、 Figure 8 shown, a connecting pipe 113 is fixedly connected to one side of the outer top end of the storage tank 111. The storage tank 111 is fixedly connected to the processing tank 9 through the connecting pipe 113. A control valve 114 is provided at one end of the outer cylindrical surface of the connecting pipe 113.

[0059] During the process of neutralizing the acidic gas generated during the emulsification process, since the amount of acidic gas generated is determined by the amount of resin poured in, when continuously pouring resin for emulsification operation, an appropriate amount of alkaline solution needs to be added to the treatment tank 9 accordingly. At this time, the control valve 114 can be opened, and by activating the hydraulic rod 115, it is extended, and the auxiliary plate 116 is synchronously raised, so that the fixedly connected pull rod 117 is also synchronously raised, and the support plate 118 is moved upward, thereby enabling the alkaline solution inside the storage tank 111 to flow into the treatment tank 9 through the connecting pipe 113, completing the automatic feeding operation and ensuring the normal progress of the work of treating harmful gases.

[0060] Usage method: When emulsifying the resin, the resin can be poured into the emulsifying tank 1 from the feed port 2, and then the servo motor 41 of the stirring mechanism 4 is started, causing the threaded rod 42 to rotate. As a result, the ball nut seat 43 drives the support plate 46 to rotate synchronously by means of the first support block 44, and the connecting plate 49 provides a supporting force during the rotation process, so that the support plate 46 fully stirs the resin in the emulsifying tank 1, making the resin fully emulsified. During the rotation of the threaded rod 42, the circulation plate 51 can rotate synchronously. At this time, hot air can be introduced into the circulation plate 51 from the air guide pipe 55 through an external hot air pipe, and then enter the heating pipe 56, flowing out from the air permeable holes of the heating pipe 56 to fully heat the mixed liquid in the emulsifying tank 1, improving the emulsification efficiency. At the same time, when it is necessary to adjust the stirring range, the support plate 46 can be limited by the clamping ball 77. At this time, the clamping ball 77 is movably stuck in the first annular groove 71, and one end of the support plate 46 is equivalent to being limited. Therefore, during the start of the servo motor 41, the threaded rod 42 causes the ball nut seat 43 to slide upward under the limited condition, so that the support plate 46 is squeezed, increasing the angle between the support plate 46 and the first support seat 45, thereby expanding the stirring range formed by the support plate 46 and enabling the resin and emulsifier in the edge area of the emulsifying tank 1 to be fully stirred. At the same time, the inner wall of the emulsifying tank 1 can be cleaned, for example, by a scraper 76, to avoid the emulsifier adhering to the inner wall of the emulsifying tank 1 during long-term emulsification operations, resulting in waste of raw materials. However, during the emulsification process of the resin, some harmful gases will be generated, such as air pollutants like formaldehyde, phenol, sulfuric acid mist, etc. At this time, by starting the conveying mechanism 8, the harmful gases in the emulsifying tank 1 flow into the treatment tank 9 through the first conveying pipe 82 and the second conveying pipe 83 and are introduced into the alkaline solution inside the treatment tank 9 in the form of small bubbles, causing the harmful gases to react with the alkaline solution, reducing the pollution problem of direct discharge. The treated gas can be filtered, adsorbed, and dried in sequence through the filter plate 101, the first adsorption cotton layer 103, and the drying cotton layer 104, so that the treated gas meets the gas emission standards and can be directly discharged from the air outlet pipe 92 without polluting the environment. Since the amount of acidic gas generated is determined by the amount of resin poured in, when continuously pouring resin for emulsification operations, an appropriate amount of alkaline solution needs to be added to the treatment tank 9 accordingly. At this time, the control valve 114 can be opened, and by starting the hydraulic rod 115, it is extended, and the auxiliary plate 116 rises synchronously, so that the fixedly connected pull rod 117 also rises synchronously, moving the support plate 118 upward, and then the alkaline solution inside the storage tank 111 flows into the treatment tank 9 through the connecting pipe 113, completing the automatic feeding operation and ensuring the normal operation of the work for treating harmful gases.

[0061] The above are only the preferred specific embodiments of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
