Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to resin production and processing equipment technical field, concretely relates to a resin production and processing reaction kettle. BACKGROUND
[0002] Resin processing is a composite modification process system with synthetic resin as the core base material, and the raw material ratio directly determines the thermal stability, mechanical strength and processing performance of the finished product. The resin powder as the main matrix needs to be combined with wood powder (to improve impact toughness), glass fiber (to enhance tensile modulus), nano pigment (to give color stability) and antioxidants, plasticizers and other processing aids to form an accurate formula combination. The mixing process needs to use special equipment such as high-speed mixer and double-screw extruder, and through processes such as segmented feeding, gradient heating and dynamic shearing in a constant temperature and humidity environment, the transformation of multi-phase materials from macroscopic mixing to microscopic dispersion is realized, especially the directional distribution of glass fiber in the resin matrix needs to be ensured to avoid stress concentration defects caused by agglomeration, and a uniform raw material system with physical and chemical properties is provided for subsequent hot pressing or injection molding.
[0003] The current mainstream reaction kettle mixing equipment has jacket heating and high-speed stirring functions, but there are significant design defects when processing high-viscosity resin systems. For example, when the mixed materials enter the external pipeline through the discharge valve, due to the influence of the resin melt viscoelasticity and the pipe wall boundary layer effect, the straight cylinder type discharge pipe with a diameter of more than 50mm is prone to form a millimeter level stagnation layer on the pipe wall due to the large length-diameter ratio. With the increase of continuous production batches, the stagnant materials repeatedly undergo thermal oxidation aging on the pipe wall, gradually carbonizing into hard coking, not only causing the effective pipe diameter to be reduced and periodic blockage to occur, but also causing black spot pollution in subsequent batches of products.
[0004] Based on this, the utility model provides a resin production and processing reaction kettle to solve the problems existing in the prior art. UTILITY MODEL CONTENTS

[0035] As per the instruction manual Figures 1-6 As shown, this utility model provides a technical solution:
[0036] A resin production and processing reactor includes a reactor body 1 and a fixed support 2. The reactor body 1 is fixedly mounted on the fixed support 2, and a stirring mechanism and an anti-obstruction discharge mechanism are provided on the reactor body 1. The stirring mechanism is located inside the reactor body 1 and is used to stir the resin raw materials added into the reactor body 1 through the feeding pipe 6. The anti-obstruction discharge mechanism is located on one side of the reactor body 1 and works in conjunction with the discharge pipe 3 installed at the bottom of the reactor body 1 to assist in the discharge of the processed resin and clean the internal cavity of the reactor body 1.
[0037] In the above description, the feeding pipe 6 is located at the upper end of the reactor body 1 and is used to add the resin raw material to be processed into the reactor body 1 during use.
[0038] In a preferred embodiment, such as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the anti-obstruction discharge mechanism includes an inner discharge pipe 13 that is slidably disposed inside the outer discharge pipe 3. A valve is provided inside the inner discharge pipe 13, and the top of the inner discharge pipe 13 extends to the inner side of the vessel body 1. During use, it can slide along the inner wall of the outer discharge pipe 3 and slide to the bottom of the lower side of the outer discharge pipe 3 to avoid the problem of incomplete discharge during the discharge process.
[0039] Specifically, such as Figure 3 and Figure 4As shown, a connecting rod 14 is provided on one side of the inner discharge tube 13, and a first movable port 15 is provided on one side of the outer discharge tube 3. The connecting rod 14 is slidably connected in the first movable port 15, so that the outer discharge tube 3 can be installed and disassembled by the guiding effect of the first movable port 15 during installation.
[0040] Specifically, such as Figure 3 and Figure 4 As shown, a mounting plate 4 is fixedly installed on the fixed bracket 2. A limiting rod 5 is fixedly connected to one side of the mounting plate 4. A movable groove 20 is opened on one side of the limiting rod 5. A wedge-shaped positioning block 19 is slidably connected to the inner wall of the movable groove 20. A positioning groove 21 is opened at the end of the connecting rod 14. The positioning block 19 is adapted to the positioning groove 21. A second spring 22 is also installed on the inner side of one side of the movable groove 20. One end of the second spring 22 is connected to the outer wall of one side of the positioning block 19.
[0041] In the above description, after the inner discharge tube 13 is cleaned, it is installed into the outer discharge tube 3. At this time, the connecting rod 14 moves upward in the first movable port 15. When the end of the connecting rod 14 contacts the positioning block 19, it squeezes the positioning block 19 until the positioning groove 21 at the end of the connecting rod 14 moves to one side of the positioning block 19. At this time, under the action of the second spring 22, the positioning block 19 can be pushed into the positioning groove 21 to achieve the positioning function of the connecting rod 14, thereby completing the positioning and installation of the inner discharge tube 13, making the outer discharge tube 3 easy to disassemble and install.
[0042] Specifically, such as Figure 5 and Figure 6 As shown, a second movable opening 23 is provided on one side of the limiting rod 5. A push-pull block 24 is slidably connected in the second movable opening 23, and the push-pull block 24 is fixedly connected to the outer wall of one side of the positioning block 19, so that the positioning block 19 can be moved by the push-pull block 24 during use.
[0043] Specifically, such as Figure 5 and Figure 6 As shown, a telescopic sleeve 16 is also fixedly connected to the bottom outer wall of the limiting rod 5. A support plate 17 is fixedly connected to the bottom telescopic end of the telescopic sleeve 16. A first spring 18 is installed on the top of the support plate 17. The top of the first spring 18 is connected to the telescopic sleeve 16, and the first spring 18 is sleeved on the telescopic end of the telescopic sleeve 16.
[0044] In the above description, the support plate 17 is used in conjunction with the discharge inner tube 13 to support the discharge inner tube 13 during material discharge. Simultaneously, the first spring 18 facilitates the reset of the discharge inner tube 13 during use and provides a buffering effect in case of obstructed resin material flow, impacts, or movement of the discharge inner tube 13 during discharge.
[0045] In use, after the materials in the vessel 1 are mixed, the push-pull block 24 is pulled to move, and the push-pull block 24 drives the positioning block 19 to move, so that the positioning block 19 is disengaged from the positioning groove 21. After the positioning block 19 is disengaged from the positioning groove 21, the connecting rod 14 slides down along the first movable port 15, so that the connecting rod 14 drives the discharge inner tube 13 to move down until the bottom of the connecting rod 14 contacts the top of the support plate 17. At this time, the discharge inner tube 13 can seal the first movable port 15. Then the valve of the discharge inner tube 13 is opened, so that the mixed materials can be discharged through the discharge inner tube 13. After the discharge is completed, pressure is applied to the connecting rod 14, causing the connecting rod 14 to move the inner discharge tube 13 to the bottom outside of the outer discharge tube 3, thereby allowing the inner discharge tube 13 to be disassembled from the outer discharge tube 3. After disassembly, the inner discharge tube 13 can be cleaned, making it easy for staff to clean the inner discharge tube 13 and avoid the occurrence of unsmooth discharge or even blockage during discharge. At the same time, the detachable inner discharge tube 13 also facilitates the cleaning of the vessel body 1 after use and the discharge of internal residues.
[0046] In a preferred embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the stirring mechanism includes a rotating shaft 8 rotatably mounted inside the vessel body 1. A first stirring blade 9 is fixedly connected to the outer side of the rotating shaft 8 at equal intervals, and a second stirring blade 10 is fixedly connected to the outer wall of the bottom end of the rotating shaft 8 at equal intervals. A stirring rod 11 is fixedly connected to the bottom of the second stirring blade 10. The stirring rod 11 is arranged around the outer side of the discharge inner pipe 13. A feeding pipe 6 is provided at the top of the vessel body 1. A mounting shell 7 is installed at the top of the vessel body 1. A drive motor 12 is installed inside the mounting shell 7. The output shaft of the drive motor 12 is connected to the top end of the rotating shaft 8 via a coupling.
[0047] In the above description, the materials required for resin processing are added into the reactor body 1 through the feeding pipe 6 according to the proportion. After the materials are added, the drive motor 12 is started to drive the rotating shaft 8 to rotate. The rotating shaft 8 drives the first stirring blade 9, the second stirring blade 10 and the stirring rod 11 to rotate, so as to achieve thorough mixing of the materials.
[0048] The implementation principle of the resin production and processing reactor described in this embodiment is as follows:
[0049] In practical use, the materials required for resin processing are added to the vessel body 1 through the feeding pipe 6 according to the specified ratio. After the materials are added, the drive motor 12 is started to drive the rotating shaft 8 to rotate. The rotating shaft 8 drives the first stirring blade 9, the second stirring blade 10, and the stirring rod 11 to rotate, thereby achieving mixing of the materials. After the materials are mixed, the push-pull block 24 is pulled to move, which moves the positioning block 19, causing the positioning block 19 to disengage from the positioning groove 21. After the positioning block 19 disengages from the positioning groove 21, the connecting rod 14 is moved downward through the first movable port 15, causing the connecting rod 14 to move the inner discharge pipe 13 downward until the bottom of the connecting rod 14 contacts the top of the support plate 17. At this time, the inner discharge pipe 13 can seal the first movable port 15. Then, the valve of the outer discharge pipe 3 is opened, allowing the mixed materials to be discharged through the inner discharge pipe 13. After the discharge is completed, Then, pressure is applied to the connecting rod 14, causing the connecting rod 14 to move the inner discharge tube 13 to the bottom outside of the outer discharge tube 3, thereby allowing the inner discharge tube 13 to be disassembled from the outer discharge tube 3. After disassembly, the inner discharge tube 13 and the inside of the vessel 1 can be cleaned, making it easy for staff to clean the inner discharge tube 13 and avoid the phenomenon of uneven discharge or even blockage during discharge. After the inner discharge tube 13 is cleaned, it is installed into the outer discharge tube 3. At this time, the connecting rod 14 moves upward in the first movable port 15. When the end of the connecting rod 14 contacts the positioning block 19, it squeezes the positioning block 19 until the positioning groove 21 opened at the end of the connecting rod 14 moves to one side of the positioning block 19. At this time, under the action of the second spring 22, the positioning block 19 can be pushed into the positioning groove 21, realizing the positioning function of the connecting rod 14, thereby completing the positioning and installation of the inner discharge tube 13.
