Description

Technical Field

[0001] This utility model relates to the field of modified phenolic resin reaction technology, specifically a modified phenolic resin mixing reaction vessel. Background Technology

[0002] Modified phenolic resins are produced by introducing other components or modifying the original structure to improve the physical properties of phenolic resins, such as brittleness, electrical properties, alkali resistance, and mechanical properties, as well as to improve the bonding performance with fiber-reinforced materials and improve the molding process conditions of composite materials. Modified phenolic resin reactors are comprehensive reaction vessels used for the production of modified phenolic resins.

[0003] When producing modified phenolic resin using a reaction vessel, it is necessary to control the temperature inside the reaction vessel. When the temperature inside the reaction vessel is raised, the requirements for heat preservation performance are high. Poor heat preservation performance will lead to rapid internal temperature dissipation, which will affect the heating reaction. Therefore, we propose a modified phenolic resin mixing reaction vessel to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a modified phenolic resin mixing reactor to solve the problem mentioned in the background art that when using a reactor to produce modified phenolic resin in the current market, it is necessary to control the temperature inside the reactor. When the temperature inside the reactor is raised, the requirements for heat preservation performance are high. Poor heat preservation performance will lead to rapid internal temperature dissipation, which will affect the heating reaction.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modified phenolic resin mixing reactor, comprising a reactor body, an inlet connected to the upper right end of the reactor body, a discharge port connected to the lower end of the reactor body, a motor installed at the upper end of the reactor body, a rotating rod connected to the output end of the motor, and a stirring rod installed at the lower end of the rotating rod;

[0006] The outer side of the reactor body is covered with an insulation sleeve, and an infusion pipe is connected to the inner wall of the insulation sleeve. One end of the infusion pipe is connected to a connecting pipe one, and the other end of the infusion pipe is connected to a connecting pipe two. The upper end of the infusion pipe is connected to an inlet pipe, and the lower end of the infusion pipe is connected to an outlet pipe.

[0007] Preferably, the side of the insulation sleeve has a through groove, and the side of the insulation sleeve is rotatably connected to an adjustment plate via a hinge.

[0008] Preferably, the stirring rod has a "U" shaped structure, and the stirring rod is distributed at equal angles with respect to the longitudinal centerline of the rotating rod.

[0009] Preferably, infusion tubes are evenly distributed on the inner wall of the insulation sleeve, and the insulation sleeves are fixed together by bolts.

[0010] Preferably, the infusion pipe is in close contact with the outer wall of the reactor body, and the infusion pipes are interconnected by interleaved connecting pipe one and connecting pipe two.

[0011] Preferably, the adjusting plate is initially locked in the through groove, and the position of the through groove is staggered with the position of the infusion tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) The modified phenolic resin mixing reactor uses a rotating rod to control the rotation of the stirring rod, which stirs and mixes the materials in the reactor, accelerates the contact reaction, and prepares modified phenolic resin, thereby improving its preparation efficiency.

[0014] (2) The modified phenolic resin mixing reactor uses a flexible and detachable insulation sleeve to keep the reactor warm. At the same time, by supplying hot water into the infusion pipe, the heating and insulation effect of the reactor is improved, so as to avoid the temperature drop inside the reactor from affecting the reaction effect and reduce energy waste.

[0015] (3) The modified phenolic resin mixing reactor can help cool down the reactor by supplying cold water into the infusion pipe and recover and utilize the heat. At the same time, the regulating plate can be rotated to open the through groove, which is more conducive to heat dissipation and cooling of the reactor. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 The present invention provides the following technical solution: a modified phenolic resin mixing reactor, including a reactor body 1, a feed inlet 2 connected to the upper right end of the reactor body 1, a discharge outlet 3 connected to the lower end of the reactor body 1, a motor 4 installed at the upper end of the reactor body 1, a rotating rod 5 connected to the output end of the motor 4, and a stirring rod 6 installed at the lower end of the rotating rod 5.

[0025] Furthermore, the stirring rod 6 has a "U" shaped structure, and the stirring rod 6 is distributed at equal angles about the longitudinal center line of the rotating rod 5. By driving the stirring rod 6 to rotate, the material in the reaction vessel 1 is stirred and reacted.

[0026] The outer side of the reactor body 1 is fitted with a heat insulation sleeve 7. A liquid delivery pipe 8 is connected to the inner wall of the heat insulation sleeve 7. One end of the liquid delivery pipe 8 is connected to a connecting pipe 9, and the other end of the liquid delivery pipe 8 is connected to a connecting pipe 10. The upper end of the liquid delivery pipe 8 is connected to an inlet pipe 11, and the lower end of the liquid delivery pipe 8 is connected to an outlet pipe 12.

[0027] Furthermore, infusion tubes 8 are evenly distributed on the inner wall of the insulation sleeve 7, and the insulation sleeves 7 are fixed together by bolts, which can easily fix the insulation sleeves 7 to the reactor body 1 to keep the reactor body 1 warm, and facilitate the disassembly and assembly of the insulation sleeves 7.

[0028] Furthermore, the infusion pipe 8 is in close contact with the outer wall of the reactor body 1, and the infusion pipes 8 are interconnected by the staggered connecting pipe 1 9 and connecting pipe 2 10, which allows water to circulate in the infusion pipe 8, and hot and cold water are used to assist in heat preservation and cooling of the reactor.

[0029] Furthermore, a through groove 13 is provided on the side of the insulation sleeve 7, and an adjustment plate 14 is rotatably connected to the side of the insulation sleeve 7 via a hinge. The through groove 13 can be exposed by rotating the adjustment plate 14, which facilitates the cooling of the reactor body 1.

[0030] Furthermore, the adjusting plate 14 is initially locked in the through groove 13. The position of the through groove 13 and the position of the infusion pipe 8 are staggered, so that the adjusting plate 14 surrounds the through groove 13 and the heat insulation sleeve 7 can keep the reactor warm.

[0031] Specifically, when using this modified phenolic resin mixing reactor, the sealing cap at the end of the feed port 2 is opened, and the material can be put into the reactor body 1 to react. The motor 4 is powered on, and the rotating rod 5 connected to the output end is rotated, thereby controlling the stirring rod 6 installed at the end of the rotating rod 5 to rotate, stirring and mixing the material in the reactor body 1, so that it comes into contact and reacts to prepare modified phenolic resin. After preparation, the material can be taken out simply by opening the sealing cap at the end of the discharge port 3.

[0032] When the modified phenolic resin reacts inside the reactor body 1, an insulation sleeve 7 is fitted over the outside of the reactor body 1. Two insulation sleeves 7 are fixed with bolts, ensuring that the temperature of the insulation sleeves 7 is maintained on the reactor body 1. The inlet pipe 11 is connected to an external water source. When heating and insulation are required, hot water can be supplied into the inlet pipe 11, then diverted to the delivery pipe 8. Through connecting pipe 1 9 and connecting pipe 2 10, the hot water fills the delivery pipe 8, and finally discharges from the outlet pipe 12, achieving heat treatment. The water circulation system uses hot water and the insulation jacket 7 to keep the reactor body 1 warm, preventing the temperature inside the reactor body 1 from dropping. When it is necessary to cool down the reactor body 1, the hot water supply can be stopped and cold water can be supplied to the infusion pipe 8 to assist in cooling the reactor body 1. At the same time, the regulating plate 14 is pulled, so that the regulating plate 14 rotates and opens on the insulation jacket 7, which facilitates the heat dissipation of the reactor body 1 through the through groove 13. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
